Embodiment Construction

[0020] combine Figure 1 to Figure 7 The manufacturing process of the pin grid of the present invention will be further described.

[0021] A needle grid manufacturing process, comprising the steps of:

[0022] a. Use a punching machine to punch out a pin-grid-shaped blank from the raw material;

[0023] b. Use the stamping device to stamp the head of the blank, that is, flatten it, make it thinner and reach the required size;

[0024] c. Use a punching device to punch the edge of the blank head to cut off the waste edge at the edge of the blank head, that is, the pin grid head will be deformed during the stamping process of step b, and The waste edge is generated at the head of the needle grid, so the waste edge can be cut off by the punching device to make the head of the needle head reach the required size;

[0025] d. The billet is processed by heat treatment technology, and the pin grid is completed.

[0026] The stamping device includes an upper die 13, a lower die 1...

Abstract

The invention discloses a needle bar making process. The process comprises following steps of a, blank obtaining, wherein a punching machine is used for punching the blank in a needle bar shape from the raw material; b, blank punching, wherein a stamping device is used for punching the head of the blank, and the head becomes thinner; c, blank punching, wherein a blanking device is used for blanking the edge of the head of the blank, and the waste side of the head edge of the blank is cut off; d, blank heat treatment, wherein the blank is treated through the heat treatment process. The needle bar making efficiency is improved, and the smoothness of the needle bar head can be ensured.

Description

technical field [0001] The invention relates to a needle grid manufacturing process. Background technique [0002] In order to drive the knitting needles to form a loop, the grid sheet in the glove machine needs to be polished at the head of the grid so that the thickness of the head of the grid is smaller than the thickness of the needle body. [0003] There are defects in the method of thinning the head of the needle grid by grinding, 1, the efficiency of grinding is low; 2, after the head of the needle grid is polished, the head is relatively rough. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a needle grid production process, which can not only improve the production efficiency of the needle grid, but also ensure the smoothness of the needle grid head. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] A needle grid manufacturing process, co...
