Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific embodiment:

[0020] According to the production process of circular machine ring-cutting velvet needles in the present invention, a set of matching molds is firstly designed according to the shape, structure and parameters of the knife needles to be processed and formed. After the molds are installed on the punching machine, the raw materials will be divided into multiple steps once. Sexual stamping into the required needle blank, figure 1 It is a knife needle that is processed and formed. The needle hook 1 and the chamfered part 11 of the needle hook 1, the needle knife 2 and the blade part 21 of the needle knife 2, and the needle body 3 (formed by stamping) are stamped and formed on a punching machine at one time. There is no need for hooking, pressing, milling, planing, etc., only subsequent heat treatment is required. The specific stamping process is divided into the following proce...

Abstract

The invention relates to a production process of a Boa-plush cutting needle for a circular knitting machine. The cutting needle is of a sheet body and mainly comprises a hook, a blade and a needle body. Barbs are formed on two opposite sides of the hook; cutting edges are formed on two opposite sides of the blade. The barbs of the hook and the cutting edges of the blade of the cutting needle are formed at one step by a punch and then subjected to heat treatment. Since the cutting needle is formed by punching directly, the individual bending process is omitted; since the barbs of the hook and the cutting edges of the blade are subjected to the punching process directly, metal density of the corresponding positions of the cutting needle is high, and service life of the cutting needle is prolonged. The conventional process of bending to form barbs at hooks through needle making equipment by multiple steps is changed, basic processing of the cutting needle is completed by the punch at one step, only the heat treatment is needed, and multiple manual operation steps are omitted, so that labor force is saved, production efficiency is increased greatly and product quality is guaranteed further.

Description

technical field [0001] The invention relates to the field of knitting machine accessories, in particular to the production process of cutting loop pile and knife needles for circular jacquard machines. Background technique [0002] Circular knitting needles are used for pulling and cutting wool during the weaving process. Such as figure 1 As shown, it is in the shape of a flat sheet as a whole, and is usually composed of a needle hook 1, a needle knife 2, and a needle body 3. The head of the needle hook 1 is a round or oval cross-section, and the needle knife 2 is in an oblique triangle structure, which has a blade Section 21. The production process of the prior art about the knife needle includes: stamping out the metal sheet figure 2 As shown in the needle blank 10, the front end of the needle blank 10 is straight, and then the needle blank is planed, milled or even headed, and the head is processed in turn to initially form a smooth needle body, and then the needle is...
