Needle bed inlaid piece and method of processing the same

Abstract

The invention discloses a neilsbed splice piece and a processing method thereof, belonging to the technical field of computer glove knitting machine spare and accessory parts. The neilsbed splice piece comprises a body, the upper end of which is provided with a groove with straight flanges; furthermore, the body is made by using SK5 carbon tool steel. The processing method of the neilsbed splice piece comprises the following steps of: blanking, stamping, notching, punching, wheel head grinding and head decorating. The neilsbed splice piece has high precision and high quality, the processing method of the neilsbed splice piece has simple working procedure, high work efficiency, low cost, and high product precision and quality.

Description

technical field [0001] The invention discloses a needle bed insert and a processing method thereof, and belongs to the technical field of spare parts of a computer glove machine. Background technique [0002] The needle bed insert processing method of the existing computer glove machine is relatively complicated. The whole process is: blanking→stamping→punching→rough grinding→levelling→heat treatment→hardness inspection→finishing→finishing two sides→grinding head→polishing decorated. At the same time, there are still the following problems in the whole process: ①Due to the insufficient hardness and toughness of the mold steel material, it is not wear-resistant, and it is easy to jump when punching the product, which affects the service life of the mold; ②The needle bed insert after punching There are a lot of burrs in the product, and the burrs need to be cleaned by rough grinding before proceeding to the next process; ③The material of the needle bed insert needs to be heat...

Problems solved by technology

[0002] The needle bed insert processing method of the existing computer glove machine is relatively complicated. The whole process is: blanking→stamping→punching→rough grinding→levelling→heat treatment→hardness inspection→finishing→finishing two sides→grinding head→lightening decorated

At the same time, there are still the following problems in the whole process: ①Due to the insufficient hardness and toughness of the mold steel material, it is not wear-resistant, and it is easy to jump when punching the product, which affects the service life of the mold; ②The needle bed insert after punching There are a lot of burrs in the product, and the burrs need to be cleaned by rough grinding before proceeding to the next process; ③The material of the needle bed insert needs to be heat-treated to reach the hardness required by the product, and the needle bed insert is very hard during the heat treatment process. It is easy to deform, and it is necessary to increase the leveling process to make the needle bed insert straight, and the leveling process will cause great damage to the surface of the needle bed insert; ④ use a grinding machine to finely grind the two sides of the needle bed insert After the process, it will leave traces on the surface of the product, which has a great impact on the appearance and quality of the product

In addition, the existing needle bed insert also has certain defects in structure: as figure 1 As shown, the 60-degree inclined edge groove 2 at the upper end of the needle bed insert 1 is not easy to adjust the gap, and there will be many defective products when punching products, which increases the product cost; at the same time, the head 3 of the needle bed insert 1 is too bulky. Large, that is, the contact area between the head 3 and other parts is too large
