Example Embodiment

[0009] The present invention will be further explained below in conjunction with the accompanying drawings:

[0010] Such as figure 1 The middle is a specific embodiment of the present invention. A square hole 6 is provided in the punch fixing seat 5, and a permanent magnet 7 is installed in the hole. A punch 1 is fixed under the punch fixing seat 5. Because the punch holder 5 receives the action of the permanent magnet 7 and concentrates the magnetic force on the end of the punch 1. The cutting core 2 used for positioning during cutting is placed at the end of the punch 1 and is attracted to the punch 1 by magnetic force. On the work surface of the punch press, a lower die holder 4 is installed. The middle of the lower die holder 4 is a square counterbore with a shape corresponding to the shape of the workpiece, which is used to place the workpiece. The workpiece is formed by stamping, but the upper end also has Riser. At this time, the punch 2 is just above the square counterbo...

Abstract

The invention belongs to the punch device of machinery processing area, which applies the new punch pin for cutting the feeder head of punch element. The inventive method comprises a punch pin, a punch-pin holder and a cutting core matched said punch head, whose main improved point is that at least one of said punch pin or cutting core has a magnetic device. The invention can be used in the punch process to absorb the cutting core via magnetic force to be inserted and drawn from the processed element. And the invention can save labor and improve efficiency in the manufacture process.

Description

【Technical field】 [0001] The invention belongs to the field of stamping equipment in mechanical processing, and is especially suitable for a novel punch that is sheared by a riser of a stamping part. 【Background technique】 [0002] In the field of mechanical processing, punching machine is a kind of processing equipment with wide application and relatively high processing efficiency. However, in the processing of some stamping parts, it is necessary to cut off the riser of the stamping part. The more common method used in the current stamping industry is mainly to locate the shear position by setting a shear core in the stamping part, especially when stamping some container-shaped stamping parts, most of them use the above-mentioned processing method , For example: processing mobile phone battery casings, especially steel containers. However, this processing method has the following disadvantages. Before stamping, the shear core needs to be manually loaded into the stamped...
