Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Example 1, a copper bar blanking apparatus based on a punch press as shown in fig. 1-3, comprising
The punch 1 comprises a cylindrical punch rod 11, a flange 12 is fixedly connected to the upper end of the punch rod 11, the end face of the lower end of the punch rod 11 serves as a movable cutting edge, and the flange 12 is fixedly connected with an actuating mechanism for vertical displacement of the punch press.
The middle part of the punch seat 2 is provided with a matching hole 21 which is in clearance fit or transition fit with the punch rod 11 and penetrates through the upper end surface and the lower end surface, one side of the punch seat 2 is provided with a feeding hole 22 which is axially orthogonal to the matching hole 21 and is communicated with the matching hole 21, and the inner diameter of the feeding hole 22 is larger than the outer diameter of the copper rod 10; the intersection of the feeding hole 22 and the matching hole 21 is used as a fixed blade; the matching hole 21 at the opposite side of the feeding hole 22 extends outwards to form a vertical groove 23 with the width larger than the outer diameter of the copper bar 10; the vertical groove can increase the blanking length of the copper bar 10 and provide a turning space for the cut-off materials.
The upper end of the base 3 is fixedly connected with the lower end of the punch holder 2, the lower end of the base is fixedly connected with a workbench of a punch press, and the middle part of the base is provided with a discharge chute 31 with the width more than or equal to the inner diameter of the matching hole 21 and an opening at the front end.
