Problems solved by technology

[0004] At present, when tapping the nut through hole, the nut blank is not fixed, and it is easy to shake, resulting in the separation or random buckling of the processed thread teeth, and the waste generated by processing is not recovered in time and falls randomly, and the efficiency is low.

Embodiment Construction

[0038] The processing technology of the nut is further described with reference to the accompanying drawings.

[0039] The processing technology of above-mentioned a kind of nut, as figure 1 shown, including the following steps:

[0040] S1. Pretreatment: Spheroidizing and annealing the blank, heating the pre-blank to 700~750°C and keeping it warm for 3~4 hours, and then performing cooling treatment, and the temperature is controlled between 650~700°C and kept for 4~6 hours. Take out of the oven and air cool to room temperature.

[0041] S2. Forming processing: put the pre-blank after the pretreatment in S1 into the cold heading machine 11 for processing and forming, and obtain a nut body with full and consistent corners and a through hole punched in the center.

[0042] S3, deoiling treatment: a deoiling pool 1 is provided at the outlet of the cold heading machine 11, combined with figure 2 As shown, in the deoiling tank 1, there is a conveying device 2 that is inclined u...

Abstract

The invention discloses a nut machining process, and relates to the technical field of nut machining. The nut machining process comprises the following steps: pretreatment, forming and machining, deoiling treatment, tapping, cleaning treatment and surface treatment. Nut bodies which are collected by an unloading device are placed in a collecting hopper, a discharging opening of the collecting hopper is connected with a conveying flow channel for conveying the nut bodies, conveying plates are arranged below the conveying flow channel at interval, a tapping device for tapping the nut bodies between the conveying flow channel and each conveying plate is arranged on one side of the conveying plate, a pushing device which is used for pushing out the tapped nut bodies to the other side of the conveying plate is arranged at one end of each conveying plate, and a collecting device for receiving the tapped nut bodies is arranged on the side, which is away from the corresponding pushing device,of each conveying plate. The nut machining process has the effects of stable machining, capability of improving the quality of nut machined products and high efficiency.

Description

technical field [0001] The invention relates to the technical field of nut processing, more specifically, it relates to a nut processing technology. Background technique [0002] A nut is a part that is screwed together with a bolt or a screw for fastening. It is used for threaded connection with studs and bolts. It is often used in various precision parts, chassis, cabinets, and automotive components; according to the material The difference is divided into: carbon steel, stainless steel, non-ferrous metals and other major types. [0003] The processing technology of the existing nut is as follows: 1. The nut body is shaped, and the blank is formed by upsetting the blank with a cold heading machine. Generally, continuous cold heading is required for 2 to 3 times, mainly for the four diagonal corners of the nut body to be full and consistent; 2. Pulling Corner, use a cold heading machine to upset a welding point with a consistent height at the edge of the end face of the fo...
