DETAILED DESCRIPTION OF THE EMBODIMENTS

[0046] The present disclosure is described in detail below with reference to the accompanying drawings.

[0047] In order to make the objective, the technical solutions, and advantages of the disclosure clearer, the present disclosure is further described in conjunction with the accompanying drawings and the embodiments. It should be understood that, the specific embodiments described herein are only used to explain the disclosure, rather than to limit the disclosure.

[0048] As shown in FIG. 1 and FIG. 2, a multidirectional synchronous punch-forming forging machine is provided. The multidirectional synchronous punch-forming forging machine includes an upper mold 1 and a lower mold 2, and the lower mold 2 is provided with multiple punching mechanisms at a side surface. This is different from a traditional arrangement, in which the punching mechanism is provided in the upper mold 1 or the lower mold 2 to realize forming of a product with a vertical punching manner. In the disclosure, the punching mechanism is provided at the side surface, which can solve the problem of inadequate material filling because a stiffening rib or a limit block is far from the center, thereby improving the finished product ratio of the product. Further, multiple punching mechanisms are provided in the disclosure. That is, when a multi-channel valve body piece is produced and processed, multiple channels can be processed and formed at the same time. Compared with a traditional forging machine, in which a single punching mechanism is provided to process and form the channels one by one, the processing efficiency is improved in the disclosure. A support 3 is rotatably provided at the lower mold 2, and at least one punching mechanism is mounted on the support 3. The punching mechanism mounted on the support 3 rotates about a lower mold cavity of the lower mold 2. In the disclosure, a rotatable punching mechanism is provided, which can form channels at different angles and adapt multi-channel valves of different structures.

[0049] For existing forging machines, a punching angle is fixed, is obtained by performing customization for a certain finished product, and is specialized. However, structures of the multi-channel valves usually are different according to different usage environments, and angles of internal channels thereof are different. If one forging machine is designed for each of the structures of the multi-channel valves, the cost is high.

[0050] In a further preferred solution of the disclosure, the upper mold 1 is provided with an upper mold cavity, and the lower mold 2 is provided with a lower mold cavity, the upper mold cavity and the lower mold cavity constituting a mold cavity of a product to be formed.

[0051] As shown in FIG. 2, the lower mold 2 is provided with a needle sleeve 4 which is provided below the lower mold cavity of the lower mold 2, and the support 3 is provided at a rear side of the lower mold cavity and is rotatably connected to the needle sleeve 4. The needle sleeve 4 is provided therein with a push needle 5 which is connected to a power mechanism 6. The power mechanism 6 drives the push needle 5 to move upwards, and the push needle 5 goes into the cavity of the lower mold 2 to act on the product to be formed and may push the product out. At least one punching mechanism is mounted in the support 3, and the support 3 rotates to drive the punching mechanism therein to move synchronously. If only one punching mechanism is required to be rotatable, one support 3 is provided for mounting of the punching mechanism. If multiple punching mechanisms are required to be rotatable, multiple supports 3 are provided for mounting of the punching mechanisms.

[0052] As shown in FIG. 5, the support 3 includes two sleeve plates 3a, i.e., an upper sleeve plate 3a and a lower sleeve plate 3a, which are sleeved outside the needle sleeve 4 and are connected to each other. The needle sleeve 4 in the disclosure is a structural component in a shape of a circular tube. The sleeve plates 3a are sleeved outside the needle sleeve 4, and the needle sleeve 4 serves as a shaft member for rotation of the support 3, so that the support 3 is rotatable about the needle sleeve 4. The support 3 in the disclosure is used for mounting of the punching mechanism, and the punching mechanism mounted on the support 3 is rotatable relative to the lower mold 2.

[0053] As shown in FIG. 2 and FIG. 5, the punching mechanism includes a guiding rail 7, a movable block 8, and a punch needle 9. The guiding rail 7 is horizontally provided, and is provided along a radial direction of the needle sleeve 4. The punch needle 9 is mounted on the movable block 8. The movable block 8 is mounted on the guiding rail 7, and moves along a length direction of the guiding rail 7. The movable block 8 mounted on the guiding rail 7 can only move along the length direction of the guiding rail 7. That is, the movable block 8 moves along the radial direction of the needle sleeve 4.

[0054] As shown in FIG. 3 and FIG. 4, an axial direction of the punch needle 9 is provided to be along the radial direction of the needle sleeve 4. The needle sleeve 4 is provided at a position right below a position of an intersection point of multiple channels in a multi-channel valve component. That is, all channels go through the position of the intersection point. The radial direction of the needle sleeve 4 goes through the intersection point. Further, the punching mechanism is provided to be mounted on the support 3, and a direction in which the movable block 8 moves is in a ray from the position of the intersection point. An angle of the movable support 3, i.e., an angle of the ray, is adjustable, so as to satisfy forming of channels in different directions.

[0055] In the disclosure, three punching mechanisms are provided, two of which are provided fixedly, and a remaining one is movably provided and mounted on the support 3. For each of the punching mechanisms provided fixedly, the guiding rail 7 is fixedly mounted at the lower mold 2, and the movable block 8 thereof moves along the guiding rail 7 fixedly mounted. For the punching mechanism mounted on the support 3, the guiding rail 7 thereof is mounted on the support 3, specifically on the upper sleeve plate 3a. The lower mold 2 is provided at a surface with several arc-shaped limiting grooves 10, and the several arc-shaped limiting grooves 10 are provided concentrically. The support 3 is mounted in a limiting groove 10, and moves along the limiting grooves 10.

[0056] As shown in FIG. 5, the punching mechanism includes a swing arm 11, which is connected to the movable block 8 via an upper connecting element 12. One end of the upper connecting element 12 is rotatably connected to the swing arm 11, and the other end of the upper connecting element 12 is rotatably connected to the movable block 8. The upper connecting element 12 is of a connecting arm structure. Specifically, the upper connecting element 12 has a Y shape. One end of the upper connecting element 12 covers an upper end portion of the swing arm 11 and is rotatably connected to the swing arm 11, and the other end of the upper connecting element 12 goes into the movable block 8 to rotatably connect to the movable block 8.

[0057] The swing arm 11 has an L-shaped structure. A middle portion of the swing arm 11 is rotatably connected to a frame 15 or the support 3 via a rotation shaft 14. A structure of the frame 15 of the forging machine is fixed. That is, the swing arm 11 mounted on the frame 15, when receiving force, rotates and swings about the rotation shaft 14. The swing arm 11 which is rotating and swinging drives the movable block 8 to move on the guiding rail 7 via the upper connecting element 12. The support 3 is rotatable around the lower mold 2 or the cavity of the lower mold 2, and the swing arm 11 mounted on the support 3 follows the support 3 and rotates synchronously. Meanwhile, swinging of the swing arm 11 due to received force is not affected, and the swing arm 11 also rotates and swings about the rotation shaft 14. The swing arm 11 which is rotating and swinging drives the movable block 8 to move on the guiding rail 7 via the upper connecting element 12.

[0058] In the disclosure, the frame 15 is also included. As shown in FIG. 3, the frame 15 is provided at the bottom with an eccentric wheel mechanism 16. The eccentric wheel mechanism 16 is connected to each punching mechanism, and the eccentric wheel mechanism 16 moves and drives multiple punching mechanisms to move synchronously.

[0059] Traditional punch presses and forging machines use a linear drive component, such as an oil cylinder, to drive punching. However, if multiple punching actions are involved in the forging machine, it is required to equip multiple oil cylinders to drive punching, and the problem of consistency of multiple punching actions is involved. In the disclosure, the eccentric wheel mechanism 16 is provided, and movement of the eccentric wheel mechanism 16 synchronously drives the multiple punching mechanisms to move, so that the problem of inconsistent movement is solved.

[0060] Specifically, a motor and a gear are provided in the disclosure. The motor drives the gear to rotate, and the gear is connected to the eccentric wheel mechanism 16. The eccentric wheel mechanism 16 converts rotating movement to vertical linear movement.

[0061] The eccentric wheel mechanism 16 is provided at the top with an adjustment shaft 17. The adjustment shaft 17 is provided vertically, and the adjustment shaft 17 is rotatable about an axis thereof. A lower end portion of the swing arm 11 mounted on the support 3 is rotatably connected to the adjustment shaft 17 via a first lower connecting element 131. Specifically, the adjustment shaft 17 in the disclosure is rotatable on the eccentric wheel mechanism 16, and the adjustment shaft 17 only rotates horizontally and can adapt to rotation adjustment of the support 3.

[0062] The eccentric wheel mechanism 16 operates to drive the adjustment shaft 17 to move vertically, and the adjustment shaft 17 which is moving vertically drives the swing arm 11 to rotate and swing about the rotation shaft 14 via the first lower connecting element 131. The first lower connecting element 131 has an H-shaped structure. An upper end of the first lower connecting element 131 covers the lower end portion of the swing arm 11 and is rotatably connected to the swing arm 11. A lower end of the first lower connecting element 131 covers the adjustment shaft 17 and is rotatably connected to adjustment shaft 17.

[0063] The eccentric wheel mechanism 16 is connected with a horizontal shaft 19 which goes through the eccentric wheel mechanism 16 and is connected to a U-shaped movement plate 18, and the lower end portion of the swing arm 11 mounted on the frame 15 is rotatably connected to the U-shaped movement plate 18 via a second lower connecting element 132. An upper end of the second lower connecting element 132 is rotatably connected to the swing arm 11, and a lower end of the second lower connecting element 132 goes into the U-shaped movement plate 18 and is rotatably connected to the U-shaped movement plate 18.

[0064] The present disclosure has been described in detail above. Specific examples are used herein to explain the principle and implementation of the present disclosure. The description of the above embodiments is only for understanding the present disclosure and the core idea. It should be noted that for those of ordinary skill in the art, several improvements and modifications can be made to the present disclosure without departing from the principle of the present disclosure, and these improvements and modifications also fall within the protection scope of the claims of the present disclosure.
