Detailed Description
The present invention will be described in further detail with reference to the drawings and examples. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
Referring to fig. 1, a specific embodiment of a knitting needle for a warp knitting machine and a processing method thereof according to the present invention includes a knitting needle for a warp knitting machine, the knitting needle includes a needle body 1, a butt 2, a hook 3 and a needle seat 4 are formed on the needle body 1, the needle body 1 is connected to the hook 3 through the butt 2, the needle seat 4 is located at one end of the needle body 1 far away from the hook 3, the needle seat 4 is located at the same side as the hook 3, and a bevel angle is formed between the butt 2 and the needle body 1.
The forming process method for forming the knitting needle comprises the following specific steps:
s1: conveying the steel strip subjected to heat treatment to a primary stamping station, and stamping for one time to form a first blank;
s2: continuously conveying the steel strip to a secondary stamping station, and carrying out secondary stamping on the first blank to form a second blank;
s3: continuously conveying the steel strip to a third stamping station, and stamping the second blank for three times to form a third blank;
s4: and continuously conveying the steel strip to a fourth stamping station, and stamping a third blank for four times to form the needle body 1.
The first blank formed in the step S1 comprises a blank hook and a blank, the blank hook is D in length, the thickness and the shear strength are D, the stamping pressure of the stamping machine is as follows, and the formed blank hook is a part which is not subjected to hooking treatment, so that the integral structure keeps certain strength, and the blank hook is not easy to bend and damage under the stamping force during the subsequent stamping forming of the blank.
The second blank formed in the step S2 is a butt 2 in the needle body 1, the length of the butt 2 is D1, the thickness of the butt 2 is D1, the shearing strength is, and the stamping pressure of the stamping machine is as follows: the utility model discloses a forming machine, including the embryo body, the embryo body is formed with 2 parts of butt, the butt 2 is formed with the bent angle with the junction punching press of embryo hook, the effect of letting out the power effect can also play improvement butt 2 in the joint strength of embryo hook when not only playing the punching press under the effect of this bent angle for knitting needle after the shaping is connected at butt 2 and needle hook 3 and is enough to keep stable structural strength, it is impaired to make the embryo hook more difficult appearance buckle when stamping forming under the effect of letting out the power of bent angle.
The third blank formed in the step S3 is the needle body 1 and the needle seat 4 in the needle body 1, the length of the needle body 1 is D1, the thickness is D1, the shear strength is, and the pressure of the punch is: the completion is to needle body 1's punching press when stamping forming for the third time, and needle body 1 and butt 2 department form the bevel for overall structure remains stable during the punching press under the effect of bevel, is difficult for appearing the perk, and the width of needle body 1 is greater than the width of butt 2, thereby makes when stamping forming, and increase punching press face reduces the whole condition that appears the punching press perk and buckle.
Step S4 is right during the step S4 the embryo hook carries out stamping forming, and the shaping of embryo hook is the hook needle 3 through step S4, the shaping is the stamping pressure of hook needle 3, and the stamping forming is buckled to the tip of embryo hook at last, because the tip department of buckling of embryo hook is the weakest, can avoid the crotch to appear impaired when carrying out the shaping at last, and the shaping pressure of crotch is minimum pressure for the condition of brittle failure is difficult to appear after the shaping, and the pressure size relation of punching press when punching press many times is: the pressure of the punch forming needle body 1 part is the largest, so that the whole punch damage condition can be reduced by rapid forming.
The needle hook 3 forms a straight hook part and a hook, the length of the hook is as follows, the length of the straight hook part is as follows, the length of the hook is 0.05-0.06 times of the length of the hook, the length of the straight hook part is the length of the hook minus the length of the hook, the length of the butt 2 is 1.35-1.48 times of the length of the straight hook part, the length of the needle body 1 is 3.14-3.18 times of the length of the butt 2, the needle body 1 comprises a slope body and a body, the slope angle is formed between the slope body and the butt 2, the length of the slope body is 0.18-0.22 times of the length of the needle body 1, the length of the body is 0.82-0.78 times of the length of the needle body 1, the butt 2 and the hook 3, and the length between the slope body 1, the butt 2 and the hook 3 keeps a proportional relation under the corresponding length relation, so that the overall structural strength is kept in the most stable state, and the length is associated with the stamping forming pressure, the proportional relation is kept under the most stable length basis, and the pressure ratio relation is kept, thereby the stamping yield is not easy to improve the stamping yield.
The working principle and the effect are as follows:
the integral knitting needle is formed in a multi-time punch forming mode, the blank part of the needle hook 3 is formed firstly during forming, so that the influence on the needle hook 3 is not easily caused in the subsequent punching process, in addition, when secondary forming is carried out, the blank part of the butt 2 and the blank connecting part of the needle hook 3 are not easily formed to form edge warping wrinkles, the blanks of the needle body 1 and the needle seat 4 are formed during the third forming, the integral forming process is almost finished, the most fragile part of the needle hook 3 is subjected to hook forming during the fourth forming, the damaged condition of the needle hook 3 is not easily caused during the last step of hook forming, the convenience in forming the knitting needle is realized, the damaged condition of the knitting needle forming is not easily caused during the forming, and the yield of the knitting needle is improved.
