Die for forming needle bed insert blank

Abstract

The invention discloses a die for forming a needle bed insert blank and belongs to the technical field of dies. The die comprises an upper die mechanism and a lower die mechanism, wherein the upper die mechanism comprises an upper die plate frame with at least one pair of guide sleeves, an upper die plate, insert male stamping dies and a pressing plate; the lower die mechanism comprises a lower die plate frame and a lower die plate; the pressing plate is connected with one side of the upper die plate; die guiding holes are formed in the pressing plate. The die is characterized in that a group of thin steel strip guiding and limiting mechanisms are formed on one side, which faces the pressing plate, of the lower die plate; guide rod holes are formed on one side, which faces the lower die plate, of the pressing plate; thin steel strip guiding and limiting mechanism assembling holes are formed in the lower die plate opposite to the thin steel strip guiding and limiting mechanisms; each thin steel strip guiding and limiting mechanism comprises a guide rod and a spring; and guide grooves are formed at one end, which stretches out of the lower die plate, of the guide rod. Besides, the die has the advantages that the stamping quality can be guaranteed; and unqualified products cannot be manufactured, so that materials are saved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a mold for forming a needle bed insert body. Background technique [0002] As known to manufacturers of computerized flat knitting machines and manufacturers using computerized flat knitting machines to produce fabrics, the knitting needles of the knitting mechanism of the flat knitting machine extend out of the needle grooves of the needle bed when transferring and receiving needles. The distance is much longer than the distance extending out of the needle bed during normal knitting, so a needle bed insert is required on the needle bed, and the needle bed insert can protect the knitting needles and prevent the knitting needles from performing operations such as transfer and stitching. During the stitching process, tampering and / or deflection occur due to protruding from the needle bed, and finally avoid broken needles and missed stitches to ensure fabric quality. Thi...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there are mainly problems of high defect rate and / or reject rate in the process of punching the needle bed insert body by punching machine (punching machine), because When the thin steel strip is introduced into the lower mold mechanism, it is easy to deviate due to the lack of guiding tube bundles, and even the thin steel strip moves when the upper mold touches the thin steel strip on the lower mold, resulting in defective products or even scrapping

[0005] In view of the deficiencies in the above-mentioned prior art, the applicant has made an in-depth search of patent literature and non-patent literature, but none of them has found any technical inspiration that can be used for reference
