A nut mold

Abstract

The invention provides a nut mold, which includes a mold body, the mold body includes a first boss, a fixing seat, and a second boss, a groove is arranged in the middle of the first boss, and the groove A cylinder is arranged inside, and a first through hole is arranged inside the cylinder, and the first through hole extends downward to the bottom of the fixing seat, and a step is provided at the bottom of the first through hole, and the first through hole is provided with a step. The bottom of the first through hole is provided with a second through hole, the bottom of the first boss is vertically provided with a fixing seat, the upper and lower sides of the described fixing seat are provided with several positioning holes, and the first The center of the boss is on the same axis as the center of the second boss, the second through hole is located in the second boss, and the outer wall of the second boss is evenly provided with several air holes around the circumference, the The vent hole communicates with the second through hole. The nut mold of the present invention has simple structure, convenient manufacture, convenient installation and disassembly, convenient transportation and reduced freight cost.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a nut mold. Background technique [0002] In the process of nut processing, the wire is usually selected first. After pickling and cold drawing, one end of the wire is connected to the feeding place of the cold heading machine. According to the mold in the cold heading machine, a hexagonal blank of the corresponding size will be punched out. The shape of the hole is the same as that of a general hexagonal nut. The old-fashioned cold heading machine cannot form the hexagonal blank at one time. At present, in the process of nut processing, it is generally forged into a rectangle first, and then it is manufactured into the required shape by sawing or grinding. Nut mold, but there is a problem of positioning deviation of the punch during processing. Such a manufacturing method not only has low production efficiency, but also produces poor performance of the finished product, which...

Problems solved by technology

[0002] In the process of nut processing, the wire is usually selected first. After pickling and cold drawing, one end of the wire is connected to the feeding place of the cold heading machine. According to the mold in the cold heading machine, a hexagonal blank of the corresponding size will be punched out. The shape of the hole is the same as that of ordinary hexagonal nuts. The old-fashioned cold heading machine cannot be formed at one time, and the hexagonal blank is formed

At present, in the process of nut processing, it is generally forged into a rectangle first, and then it is manufactured into the required shape by sawing or grinding. Nut mold, but there is a problem of positioning deviation of the punch during processing. Such a manufacturing method not only has low production efficiency, but also produces poor performance of the finished product, which leads to unstable quality of the finished nut product; the existing nut mold Poor air permeability, which affects the product quality when processing products

[0003] In order to solve the above problems, the present invention provides a simple structure, reduces vibration, solves the problem of positioning deviation of the punch during processing, improves productivity, ensures product quality, simplifies the process, effectively controls costs, and reduces Nut molds with human labor intensity
