Abstract

The invention discloses a device for adjusting the roller type punching distance. The device comprises two guide press rollers in up-and-down compression joint, two punching press rollers in up-and-down compression joint and two correction press rollers in up-and-down compression joint. A plate sequentially penetrates the guide press rollers, the punching press rollers and the correction press rollers. Pressing rollers are arranged on the two sides of the punching press rollers correspondingly. A speed measurement roller is arranged between the punching press rollers and the correction press rollers. Convex molds are evenly arranged on the surface of the punching press roller located on the upper portion. Concave molds in one-to-one correspondence to the convex molds are arranged on the surface of the punching press roller located on the lower portion. Cutting strips are arranged at the tops of the convex molds. Rubber outer edges are fixed to the outer sides of the cutting strips. Thecutting strips and the rubber outer edges are attached to the inner side walls of the concave molds in a sliding manner. Rubber flanges are arranged at the tops of the concave molds. A groove is formed in the top of each rubber flange. Multiple annular rubber pieces are arranged on the inner wall of each groove. According to the device, the defects in the prior art can be overcome, and the punching position accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a device and a method for adjusting the pitch of roller punching holes. Background technique [0002] The roll punching process is to install multiple pairs of punches and dies on the rolls, and the rolls are synchronized and rotated in opposite directions to achieve the purpose of high-speed continuous punching. It has the advantages of high production efficiency, low punching force, low noise, small footprint and small investment. It is suitable for metal coils with a thickness of less than 3.0mm, and can realize punching, blanking, edge trimming and incision. It shows broad application prospects in the fields of construction, storage, packaging and automobiles. [0003] Checking the existing literature, it can be known that the strip relies on the friction between it and the roll to move forward, so the strip advance speed is the same as the roll rotation speed. T...
