AI Technical Summary

Technical Problem

The existing horizontal needle straightening machines fail to effectively control the thermal stress of the metal needle after heat treatment, affecting its shape and dimensional stability, thereby reducing processing accuracy and product quality.

Method used

A straightening machine for horizontal needle processing is designed, equipped with a cooling device, which effectively controls the heat generated during the straightening process through the bellows and fans, and reduces the thermal deformation of the metal needle.

Benefits of technology

Through the setting of the cooling device, heat accumulation is effectively controlled, and processing accuracy is maintained, ensuring that the size and shape of the horizontal needle meet the precise requirements and improving product quality.

Abstract

The utility model belongs to the technical field of flat knitting machine needle correction, and particularly relates to a straightening machine for flat knitting machine needle processing. A moving device is arranged at the top of the bottom plate, a fixing block is fixedly connected to the top of the moving device, a clamping groove is formed in one side of the fixing block, a clamping device is connected to the top of the fixing block in a penetrating mode, a stand column is arranged on the back face of the clamping device, and a cross beam is fixedly connected to the top of the front face of the stand column. An electric telescopic rod is arranged at the bottom of the cross beam, a pressing head is fixedly connected to the bottom of the electric telescopic rod, a supporting plate is fixedly connected to the middle of the top of the moving device, and a cooling device is arranged on the front face of the supporting plate. Through the arrangement of the cooling device, heat generated in the straightening process can be effectively controlled, thermal deformation of the metal needle is reduced, and therefore higher machining precision is kept, it can be guaranteed that the size and the shape of the flat knitting machine needle meet the precision requirement, and the product quality is improved.
