Embodiment

[0022] Based on the existing riveting device, the present invention mainly changes the outer circular shape of the head of the stripping plate, so that the head of the stripping plate has a convenient solution in the case of parts interference, and can promptly eliminate product quality problems generated during the production process. And the changed shape of the outer circle of the head of the release plate does not affect its function. The invention solves the method of quickly finding the cause of the failure.

[0023] Specific structure:

[0024] A riveter with a stripping plate of a specific shape head. The rivet includes a stripping plate, a guide post and a stamping unit connected in sequence. A protrusion 4 is provided in the middle of the side of the stripping plate that contacts the stripping part, such as figure 1 As shown, the raised shape is half arc-shaped, half of which is formed by two symmetrical arcs. If the radius of the arc-shaped half of the raised arc i...

Abstract

The invention relates to a press riveter with a special-shaped head stripping plate. The press riveter comprises the stripping plate, a guide column and a stamping unit which are connected in sequence. A protrusion is arranged in the middle of the face, making contact with a stripping part, of the stripping plate. One half of the protrusion is in a circular-arc shape, and the other half of the protrusion is composed of two sections of symmetrical circular arcs. A square stamping hole is formed in the middle of the protrusion, and a total of four screw holes are formed in the periphery of the stripping plate. The press riveter further comprises damping nails which are arranged on the side faces of the protrusion in an embedded mode, and the stamping unit comprises an upper air chamber and astamping rod connected to the upper air chamber. During stripping, the protrusion and the to-be-stripped part are attached, the stamping unit conducts stamping, and the stripping process of the specific part is completed. Compared with the prior art, the press riveter has the advantages that the press riveter adapts to stripping of the specific part, the shape and functions of an original stripping plate are not changed, and the product quality problem is eliminated in time.

Description

technical field [0001] The invention relates to a riveting device, in particular to a riveting device with a head stripping plate of a specific shape. Background technique [0002] During the riveting (stamping nut) process, there is a problem of not taking off the waste material, and the waste material blocks the nut hole. As a result, every part must be inspected during the production process, which seriously affects the quality and output. Because the stripping plate has a hole in the middle and is equipped with damping nails, in order to enhance the strength of its mechanical parts, the outer circle size of the stripping plate head is guaranteed. This type of stripping plate is only suitable for use without interfering with the parts. The actual outer circle (shape) of the stripping plate head has the disadvantage of being interfered by parts. Contents of the invention [0003] The object of the present invention is to provide a riveter with a stripping plate with a ...
