Needle bed insert blank body punching mould

Abstract

A needle bed insert blank body punching mould belongs to the technical field of moulds. The needle bed insert blank body punching mould comprises an upper mould mechanism and a lower mould mechanism, wherein the upper mould mechanism comprises an upper mould plate rack, an upper mould plate and an insert embossing mould; a lower mould mechanism comprises a lower mould plate rack and a lower mould plate; the needle bed insert blank body punching mould is characterized in that: one end of the insert embossing mould facing to one side of the lower mould plate is higher than the other end thereof; the height difference between the higher end and the lower end is equal to the thickness of a needle bed insert blank body to be punched and moulded; the upper mould mechanism also comprises a material pressing plate; the material pressing plate is connected with one side of the upper mould plate; a guiding mould hole is formed on the material pressing plate; a group of thin steel strip guiding and limiting mechanisms is arranged on one side of the lower mould plate; a material guiding rod hole is formed on one side of the material pressing plate; thin steel strip guiding and limiting mechanism installing holes are formed on the lower mould plate; each of the thin steel strip guiding and limiting mechanisms comprises a material guiding rod and a spring; and a material guiding groove is formed at one end of the material guiding rod. The needle bed insert blank body punching mould has the advantages that: the quality of the needle bed insert blank body is ensured; equipment investment can be reduced; and deviation of a thin steel strip can be avoided.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a mold for stamping 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. Th...

Problems solved by technology

In addition, there are still the following technical problems in the punching dies for the needle bed insert body in the prior art. When the step-by-step automatic feeding mechanism sends the steel strip to the lower die plate, it is easy to drift and shift, thus affecting the punching effect and even appearing scrap and wasted material
