Abstract
The utility model discloses an improved spring needle. A spring needle main body comprises a needle body front end, tail-end sawtooth clamping part of the needle body, and a middle connecting part, which are integrally formed by punching, wherein the lower end of the part of the middle connecting part, close to the needle body front end, is connected with a butt for loop transfer; a limiting groove is arranged at the lower end of the part of the middle connecting part, close to the tail-end sawtooth clamping part of the needle body; and an elastic part in sliding contact with the bottom in a needle groove of a flat knitting machine is arranged at the upper part of the part of the tail-end sawtooth clamping part of the needle body, connected with the middle connecting part. According to the improved spring needle, a new spring needle processing mode is created, and the production efficiency of the spring needle is improved.
Description
Technical field
The utility model relates to the flat machine technical field, particularly relates to a kind of improved spring needle.
Background technology
At present, the processing technology of conventional springs pin is a body acupuncture, forms with the steel band punching out, and is high to the punch die requirement, extremely low towards the material utilization rate, variable row during hot-working is handled, and the product flatness is not high, causes phenomenons such as waste of material easily.
Summary of the invention
The problem that the utility model need solve is, traditional spring needle requires high in process to punch die, extremely low towards the material utilization rate, variable row during hot-working is handled, and the product flatness is not high, causes the problem of waste of material easily.
In order to address the above problem; The utility model provides a kind of improved spring needle; This spring needle main body comprises needle body front end, needle body tail end sawtooth screens portion, middle interconnecting piece; The interior slip of needle tray that said spring needle is configured in straight-bar machines is provided with; Said middle interconnecting piece is between said needle body front end and needle body tail end sawtooth screens portion, and said needle body front end, middle interconnecting piece and needle body tail end sawtooth screens portion integrated punching form, and uses the pin bell at said middle interconnecting piece near the lower end connection barring-on at the position of said needle body front end; Said connecting portion is provided with place's limited impression near the lower end at the position of said needle body tail end sawtooth screens portion; Connect the elastomeric element that is provided with on the position of middle interconnecting piece with the needle tray inner bottom part sliding-contact of straight-bar machines in said needle body tail end sawtooth screens portion, the part of said elastomeric element and spring needle main body are connected to and are welded to connect, and remainder is arranged on outside the spring needle main body.
The further improvement of the utility model is: being welded to connect of said elastomeric element and spring needle main body.
The further improvement of the utility model is: the elastomeric element of telling is to be processed by steel wire.
The further improvement of the utility model is: said elastomeric element and spring needle main body are connected to laser weld.
The further improvement of the utility model is: said elastomeric element separates with the spring needle main body to be processed.
Spring needle is in process, and elastomeric element and spring needle main body are not that the one punching out processes, and elastomeric element and spring needle main body are to be welded to connect; Thereby started a kind of new spring needle processing mode, it is high that spring needle after the improvement is had towards the material rate, greatly reduces material cost; Solved in the heat treatment process variable capable shortcoming; Obtain good product flatness, guaranteed consistency of product, improved production efficiency of products.
Description of drawings
Fig. 1 is the side view of the utility model.
Wherein: 1-needle body front end, 2-sawtooth screens portion, 3-connecting portion, 4-barring-on are used the pin bell.5-elastomeric element.
The specific embodiment
The utility model discloses a kind of improved spring needle; Make the spring needle that becomes with the traditional handicraft integrated punching originally improve the spring needle that becomes split processing; Its purpose be to solve traditional spring needle in process, punch die is required high, extremely low towards the material utilization rate, variable row during hot-working is handled; The product flatness is not high, causes the problem of waste of material easily.
The spring needle main body comprises needle body front end 1, needle body tail end sawtooth screens portion 2, middle interconnecting piece 3; It is characterized in that; Its configuration with in the needle tray of straight-bar machines, slide to be provided with, said middle interconnecting piece 3 between said needle body front end 1 and needle body tail end sawtooth screens portion 2, said needle body front end 1, middle interconnecting piece 3 and the 2 integrated punchings formation of needle body tail end sawtooth screens portion; This spring needle is arranged in the knitting needle; The tail end and the stop wire in the pin main body of pin main body of a side that is arranged at needle tray is chimeric each other, and sawtooth screens portion 2 increases the resistance that spring needle slides up and down at work, and pin body front end 1 forms with sawtooth screens portion 2 integrated punchings of pin main body; Middle interconnecting piece 3 connects barring-on with pin bell 4 and sawtooth screens portion 2; Between said connecting portion 3 and sawtooth screens portion 2, being provided with the elastomeric element 5 with the needle tray inner bottom part sliding-contact of straight-bar machines, particularly is not that integrated punching forms between this spring needle main body and the described elastomeric element 5, and this elastomeric element and spring needle main body are to be welded.
Said elastomeric element 5 is to be processed by steel wire.
Said elastomeric element 5 is connected to laser weld with the spring needle main body.
Said elastomeric element 5 is to separate to process with the spring needle main body.
