Abstract

The invention provides a strip puncher pin connecting structure for powder forming equipment. The strip puncher pin connecting structure consists of a puncher pin stand, a strip puncher pin and threaded rods; a dovetail groove is formed in one end, in contact with the strip puncher pin, of the puncher pin stand; one end, in contact with the puncher pin stand, of the strip puncher pin is designed to be the shape fit with that of the dovetail groove; the puncher pin stand is in clearance fit with the strip puncher pin; and the puncher pin stand and the strip puncher pin are fixed by the threadedrods. The strip puncher pin connecting structure for the powder forming equipment does not need to adopt a welding fixing mode in the prior art, so that welding deformation is avoided, the perpendicularity and the parallelism of the strip puncher pin are ensured better; and damage to a material structure of the strip puncher pin due to high-temperature welding is avoided so that the life of the puncher pin is prolonged. In addition, when the strip puncher pin is damaged and is required to be replaced, an operator simply replaces the strip puncher pin with a new one, without replacing the strip puncher pin and the puncher pin stand at the same time, so that materials are saved and the production cost is lowered.

Example Embodiment

[0018] In order to make the technical problems, technical solutions, and beneficial effects solved by the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0019] Please refer to Figure 1 to Figure 6 An embodiment of the present invention provides a long strip punch connection structure for powder molding equipment, which is composed of a punch seat, a long strip punch and a screw. The end of the punch holder contacting the long punch is designed with a dovetail groove, the end of the long punch contacting the punch holder is designed to match the shape of the dovetail groove, and the punch holder and the long punch are gaps Match and fix by screw. The assembly of the punch holder and the long punch is a clearance fit, and is fixed by two screws.

[0020] The connecting structure of the strip punch using the prior art is usually fixed by welding, such as figure 1 As mentioned, welding deformation is often unavoidable, and the perpendicularity and parallelism of the punch cannot be guaranteed; high-temperature welding itself affects the structure of the punch material and reduces the service life of the punch. At the same time, when the punch is damaged and needs to be replaced, the punch and the punch holder need to be replaced together, resulting in waste.

[0021] The long-strip punch connection structure for powder molding equipment provided by the present invention is composed of a punch seat, a long-strip punch and a screw, adopts a dovetail groove tight-fitting connection mode, does not need to adopt the welding fixing method in the prior art, and avoids The welding deformation is improved, the perpendicularity and parallelism of the long strip punch are better guaranteed; the damage to the punch material structure due to high temperature welding is avoided, and the service life of the punch is extended. In addition, when the punch is damaged and needs to be replaced, there is no need to replace the long punch and the punch holder together, and only the punch needs to be replaced, thereby saving materials and reducing production costs. Since there is no need for welding, the surface of the punch will not be oxidized and discolored, which increases the aesthetic appearance of the mold.

[0022] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection of the present invention. Within range.
