Embodiment approach

[0018] As a preferred embodiment of the present invention, there are multiple fixing holes 10 and screw holes, and the size and structure of the fixing holes 10 and the screw holes are the same. Multiple identical screw holes and fixing holes ensure the stability and consistency of the connection.

[0019] As a preferred embodiment of the present invention, the sealing ring 7 and the limiting ring 9 are both made of rubber material and integrally formed by fusion. The rubber material has a certain degree of flexibility and has the effect of an oil seal.

[0020] As a preferred embodiment of the present invention, both the forging body 1 and the fixing pin 2 are made of titanium alloy. Through the composition of titanium alloy material, it can withstand strong punching force and improve the life of the mold.

[0021] As a preferred embodiment of the present invention, the locking thread 6 at one end of the connecting column 5 matches the thread structure of the locking hole a...

Abstract

The invention discloses an oil seal bolt processing die. The oil seal bolt processing die is composed of a forging body and a fixing pin, wherein a female die is arranged at one end of the forging body, fixing holes are formed in the other end of the forging body, a connecting column is arranged at one end of the fixing pin, one end of the connecting column and one end of the fixing pin are forgedinto a whole, the other end of the connecting column is provided with locking threads, and the locking threads are locked and fixed to the fixing holes in the bottom of the forging body; and a die hole is formed in the female die, a sealing ring is arranged outside the die hole, a steel ring is arranged inside the sealing ring, a limiting ring is arranged at the bottom of the sealing ring, fixation holes are formed in the sealing ring, and the fixation holes are fixed to screw holes in the female die in the mode that screws penetrate through the fixation holes. Through the design of the sealing ring, the stamping friction between a male die and the female die is effectively reduced; and meanwhile, the sealing ring is made of a rubber material, a certain oil sealing effect is achieved, lubricating oil in a stamping device is largely prevented from entering the female die, and thus the sealing performance of a stamping process is enhanced.

Description

technical field [0001] The invention relates to the technical field of bolt processing equipment, in particular to an oil seal bolt processing mold. Background technique [0002] Various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] Since the lubricating oil on the stamping die easily enters the die when the bolt die is stamped, if there is too much oil in the die, it will easily lead to stamping misalignment and inaccurate stamping. In order to solve the above problems, therefore, we propose an oil seal bolt processing die. Contents of the invention ...
