s3: a third section of punching, namely, transferring the workpiece from the second section of punching station to the third section of punching station while keeping the workpiece relatively static, fixing the workpiece in an indexing groove at the bottom of the third section of punching station, fastening an upper die and a lower die to fix the workpiece, adjusting the height of a punching needle arranged on the side of the die to a preset position, and starting a telescopic device to drive the punching needle to perform third section punching on the side wall of the workpiece;
s4: and continuously punching a plurality of sections, wherein the side surface of the workpiece is sequentially punched by the punching needle by adjusting the rotating angle n of the index plate, the height h of the punching needle is adjustable, and the rotating angle n and the height h are set according to the processing parameters.
Furthermore, each station is provided with a positioning assembly, so that the workpiece is accurately positioned when moving among the stations.
Furthermore, the punching needle comprises one or more combined fixed devices arranged at one end of the telescopic device.
The working principle of the invention is as follows: and (4) carrying out a punching process on the side wall of the pipe body through continuous multiple times of single-side punching. The hole punching device is characterized in that the hole punching device punches holes through the matching of a punching needle arranged on one side of the pipe body and a driving part by rotating the pipe body by a specified angle every time through an index plate arranged in the lower die. The distribution of punching needles and the rotation angle of the dividing plate are set according to the size and the requirement of the product. Go up the lower mould lock, through the matching location of locating lever and constant head tank avoid the body dislocation phenomenon to appear in the mould die cavity, still be equipped with the support column simultaneously in the inside of body for the support body is not by the pressure extrusion deformation that the needle of punching a hole was applyed, treats that the die cavity punches a hole again after fixing the body.
The invention has the beneficial effects that: through continuous and repeated drilling, the impact force caused by punching multiple holes simultaneously at a single time on the pipe body is reduced, the deformation of the pipe body is avoided, and the success rate of product production is effectively ensured.
