Description

Technical Field

[0001] The utility model relates to the technical field of sinker processing for computer flat knitting machines, and particularly relates to a heat treatment device for sinker processing. Background Art

[0002] At present, sinkers have been widely used on computer flat knitting machines at home and abroad. The sinkers are arranged between two knitting needles and are located in the sinker grooves at the tooth openings of the needle beds. The sinkers on the two needle beds are arranged opposite to each other, and the sinker heels are controlled by cams to swing the sinkers back and forth. When the knitting needles rise to doff the loops, the sinkers in the front and rear needle beds close. When the knitting needles descend to bend the yarn into loops, the front and rear sinkers open. It can well control the old loops and new yarns on each knitting needle and help the knitting needles smoothly complete operations such as tucking, doffing, and purling.

[0003] Since the thickness of the sinker is only about 1 mm, it is easy to generate a basin shape during stamping. The sinker with a basin-shaped structure often needs to be ground flat by a grinding machine in the front and back directions later. In order to cope with the subsequent grinding, the thickness of the original stamping blank needs to be increased. This processing method is not only inefficient but also causes great material waste.

[0004] The existing sinkers need to be heat-treated after stamping to improve the product performance and quality. The hardness and wear resistance of the sinkers are improved by heating and quenching. However, the existing heat treatment devices have great limitations and are single-functional and cannot meet the requirements. The current heat treatment devices do not have the function of reshaping. In order to reshape the sinker with a basin-shaped structure, it often needs to be reheated, resulting in great energy waste. Summary of the Invention

[0005] The utility model designs a heat treatment device for sinker processing to solve the above problems. A stamping station is arranged between the heating station and the quenching station. The heated sinker can be reshaped through the cooperation of the stamping upper die and the stamping lower die. By adopting this design, not only the functions of the heat treatment device are increased, but also the cost can be greatly reduced and the production efficiency can be improved.
