The present invention relates to a conveying accuracy related fault detectable integrated sheet body punching and grinding assembly, including frame, conveying trough seat and processing frame. The processing frame is provided with a punching device and a grinding device, the frame is provided with a feed motor and feed screw. The feed screw is sleeved with a movable feed block; the movable feed block is fixedly connected with a movable feed seat, and the movable feed seat is provided with a feed lift cylinder, the feed lift cylinder is provided with a feed lift block. The feed lift block is evenly disposed with feed blocks that are capable of passing through the feed conveying trough, and a vertically oriented beam emitter is disposed on the portion that the feed lift block corresponds with the grinding device. A beam receiver is embedded in the lower surface of the grinding component of the grinding device; the present invention provides a beam emitter capable of emitting a vertical beam on the feed block corresponding to the grinding device, matching with the beam receiver disposed under the grinding head of the grinding device, which may accurately detect the feeding position of the feed block, thereby improves the punching and grinding precision of sheet bodies.

The present invention relates to a fault detectable sheet body fixed distance conveying and punching assembly, which may include a rack, a conveying trough seat, a feeding trough, a processing rack and a punching device. On the rack is provided a feed motor and a feed screw. The movable feeding block is sleeved on the feed screw and the movable feeding seat is fixedly connected to the movable feeding seat. On the movable feeding seat is provided a feed lifting cylinder and on the feed lifting cylinder is provided a feed lifting block. On the feed lifting cylinder are equally provided feed blocks which may go through the feeding trough. On the processing rack is also provided a position detecting device which may include a detecting lifting cylinder provided on the processing rack. Under the detecting lifting cylinder is connected the detecting block. On the both sides of the detecting block is provided an acoustic wave range finder. The present invention includes a position detecting device, which may measure the position of the feeding block on the processing station by lifting the acoustic wave range finders on the position detecting device, and conduct integrity check to the fixed distance feeding part and maintain the entire assembly.

The present invention relates to an automatic fault diagnosable integrated sheet body punching and grinding assembly, including a frame and a conveying slot seat, a processing frame is provided on the conveying slot seat, the processing frame is sequentially provided with a punching device and a grinding device; the frame is provided with a feeding motor and a feeding screw cooperating with each other, the feeding screw is sleeved with a movable feeding block, and the movable feeding block is fixedly connected with a movable feeding seat, the movable feeding seat is provided with a feeding lift cylinder, the feeding lift cylinder is provided with a feeding lift block; the feeding lift block is evenly disposed with feeding blocks that can pass through the feeding slot, and the distance between the processing portion of the punching device and the grinding device is the same as that between the adjacent two feeding blocks. In the present invention, the conveying slot seat cooperates with the fixed distance feeding part to realize the fixed distance feeding of the sheet bodies, the punching device and the grinding device are provided sequentially on the conveying slot seat, which enables continuous automatic punching and grinding of sheet bodies, thereby greatly improves the efficiency of punching and grinding of the sheet bodies.

To provide a pipe drilling tool for forming, in a pipe, a hole for injecting a non-oxidizing gas such as nitrogen, when joining pipes such as refrigerant pipes by brazing, wherein the pipe drilling tool has a compact configuration allowing work thereof to be performed by the drilling tool being gripped by the hand of a user, does not readily generate burrs, and prevents cutting residue and burr residue from remaining in the pipe.

The present invention relates to an electrode shaping apparatus having a sheet transfer unit, a fixing unit, a punch unit including a center punching unit and a side punching unit, wherein the center punching unit includes a hole punching member and a notching pilot pin, the electrode shaping apparatus configured to reduce a step that may occur during notching of an electrode, and an electrode shaping method using the same.

A method for disposing of a slug produced in a hole punching operation on a hollow profile is provided. The method includes the steps of providing a hollow profile; cutting at least one predeterminable hole or slug contour path into the hollow profile by means of a cutting device; leaving a residual web of the hole or slug contour path; moving a receiving device into the hollow profile; moving a punch from a first position into a residual-web-removing second position in such a way that the slug thereby produced is received by the receiving device; and moving the receiving device out of the hollow profile.
