The present invention is characterized by the process comprising the steps of securing a metal plate by pinching both sides thereof with a clamping device, or securing a metal rod by pinching at least two opposite-facing portions on the periphery thereof with a clamping device; splitting longitudinally by slitting or cleaving the metal plate, or the metal rod, by pressing a slitting punch or a cleaving punch against the face of one end of the metal plate, or the metal rod; and advancing the splitting further by repeating the same operation of pressing the same punch stated above against the cleft of the splitting; and is characterized further in that, in each time of the press-splitting operation, the position of the clamping device on at least one side is moved in advance of the next pressing by a stroke corresponding to the distance from one end of the metal plate, or the metal rod, to the distal end of a split-desired portion.

A multifunctional engineering accessory with 6-bar mechanism comprising: a 6-link rod clamping device, a shear-fork separation device, a shearing device and locking device. Motion and lock of the 6-link rod group are implemented through a swing hydraulic cylinder of the 6-link rod clamping device to implement extending and withdrawing processes of a clamping paw. The shear-fork separation device can separate an accessory holder to meet the lateral dimension requirement of the multifunctional accessory. The shearing device can implement shearing and crushing function of multifunctional accessory, and the motion location of the accessory holder is confirmed by locking device while at the same time it sustains counterforce generated when the multifunctional accessory is working. The hydraulic ram is the power supply of the whole device. The present disclosure combines shearing, crushing and clamping on one accessory, and the structure design is a novelty, the driven pattern is reasonable, and the manufacturing technology is simple and easy to operate. The device can implement the crushing and moving processes of ruins better, while at the same time improving the economic efficiency.

The various embodiments disclosed and pictured illustrate a hammer for comminuting various materials. The embodiments pictured and described herein are primarily for use with a rotatable hammermill assembly. The hammer includes a connector end having a rod hole therein, a contact end for delivery of energy to the material to be comminuted, and a neck affixing the connector end to the contact end. The neck is formed with at least one neck recess therein. In other embodiments, one or more shoulders are positioned around the periphery of the rod hole for added strength. In still other embodiments, the contact end is configured with more than one contact surface.

After a connecting rod for an engine is formed, it is broken or fractured at a fracture point to allow the connecting rod to assemble around a portion of a crankshaft. However, before fracturing the connecting rod, the connecting rod is provided with a layer of paint across the eventual fracture point such that when the connecting rod is fractured the paint extends across both sides of the fracture point. Also before fracturing the connecting rod, serial numbers or symbols are etched into the paint on either side of the eventual fracture point. These serial numbers are unique to that connecting rod, and have similar indicia on either side of the connecting rod. The combination of the paint and serial numbers increase the ability of an assembly worker to assure matching parts of an original connecting rod are re-attached during assembly about the crankshaft.

A height adjustment apparatus that can reduce a load to trim a can body is provided. The height adjustment apparatus 1 is adapted to adjust a height of a can body to a desired height by trimming one of opening ends of the can body. The height adjustment apparatus comprises: mandrels on which the can body is individually mounted and which revolve along a predetermined orbit while rotating; outer blades arranged around the revolution orbit of the mandrels; an inner blade fitted onto each mandrel to trim the opening end of the can body together with the outer blade; and a vertical reciprocator that gradually changes a level of the opening end of the can body with respect to a level at which the outer blade and the inner blade are situated from an upstream side toward a downstream side in a revolution direction of the mandrel.

A method for combined shearing of a steel plate adopts a combination of unrolling and pendulum shearing with laser cutting, wherein after a steel roll is cut by unrolling and pendulum shearing to obtain sheets having a specified length, a part or all of the sheets are directly conveyed to a stack as finished sheet materials and the other part or all of the sheets are transferred to a laser cutting line by means of lateral material discharge from a unrolling and pendulum cutting line, and are picked up by a loading robot and moved to a laser cutting position to subject to a secondary cutting, so as to finally obtain profiled sheet materials which are picked up by a discharged material handling and stacking robot for an operation of stacking the finished products. By a method and system for combined shearing of a steel plate, the present invention achieves laser cutting of a profiled material by lateral material discharge from a blanking from a pendulum cutting line, and can share other functional segments of a production line; meanwhile, two blanking methods are combined to achieve cutting of a sheet of any shape, optimizing and improving the function of the production line and reducing the footprint and equipment investment costs.

A method and device provides for alternately cutting off material by back-and-forth movement of multiple vehicles. Specifically, the device is a cut-off machine for alternately cutting off material by back-and-forth movement of multiple vehicles. The cut-off machine is at least provided with two cutter vehicles, wherein these vehicles are installed on tracks parallel to material. The tracks are arranged around the material side by side. Each vehicle moves back and forth in accordance with a set sequence. Cutters on the vehicles alternately cut off the material in accordance by a set length. The larger the number of vehicles, the longer the possible stroke of each vehicle can be, such that the cutters have more time to cut off the material. Accordingly, the cut-off machine can be adapted to higher material forming speeds in a production line.
