Problems solved by technology

[0003] The stamping dies of the prior art have the following defects: each time a screw is punched, five steps of mold opening, loading, stamping mold clamping, mold opening, and demoulding need to be carried out separately, and as many screws as needed to be stamped need to be repeated as many times as necessary. The speed is slow and the efficiency is low, and continuous stamping and forming cannot be performed; secondly, because the round bar is placed between the upper mold and the lower mold when discharging, in this way, if the mold opening range is too small before discharging and when the mold is opened, two The distance between the molds is not enough, it is difficult for people to put the round rod in, but if the mold opening range is too large, the stroke of the punch will be increased when the mold is opened and closed, which will consume more time and further reduce the efficiency. There is a certain risk of feeding between the two molds. In case the punch is accidentally started, it may hurt the hands; moreover, because the opening of the lower mold is upward, the demoulding process is too inconvenient; in addition to the above defects, the prior art There is still a huge defect in the stamping die of the company. A set of stamping dies can only be punched once and processed to form a screw of one shape. In the actual production process, the screw often needs to punch out the screw head and punch out the small inner part of the screw head. Multiple processes such as hexagonal holes, enlarged inner hexagonal holes, and chamfering can be finally formed. Then, it is necessary to use multiple sets of stamping dies to repeat the process of mold opening, loading, stamping mold clamping, mold opening, and demoulding. , so it is quite cumbersome and inefficient

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 , figure 2 , image 3 As shown, the continuous composite stamping die of the present invention includes an upper die 1 and a lower die 2, and the upper die 1 is connected with punching equipment such as a punching machine. The lower mold 2 includes two lower supports 3 , a lower main shaft 4 , a lower transmission gear 5 driven by an electric motor and a lower turntable 6 . Specifically, the lower transmission gear 5 is directly meshed with the output gear of the motor output shaft or meshed via a belt. The two ends of the lower main shaft 4 are respectively fixed with the two lower supports 3 . The lower transmission gear 5 and the lower turntable 6 limit the position in the circumferential direction, that is, the end surface of the lower turntable 6 close to the lower transmission gear 5 is evenly distributed alon...

Abstract

The invention discloses a continuous composite stamping die. The continuous composite stamping die comprises an upper die (1) and a lower die (2). Two ends of a lower spindle (4) are fixed with two lower supports (3) respectively, a lower transmission gear (5) and a lower rotation disc (6) are rotatably sleeved on the lower spindle (4), a plurality of radial through holes (7) are formed in the lower rotation disc (6), and a nozzle is arranged on the lower die (2). Two ends of an upper spindle (11) of the upper die (1) are fixed with two upper supports (7) respectively, and an upper transmission gear (12) and an upper rotation disc (13) are limited circumferentially and are ratatably sleeved on the upper spindle (11). Three stamping columns (14) are arranged on the upper rotation disc (13), and a hexagonal hole stamping punch (15), a hexagonal hole expansion punch (16) and a chamfering punch (17) are arranged successively on the three stamping columns (14). By means of the stamping die, the punching process is fast in speed, high in efficiency, safe and convenient.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a continuous compound stamping die for stamping screws. Background technique [0002] The stamping die of the traditional stamping screw includes a lower die and an upper die. The upper end of the lower die is provided with a blind hole that matches the shape of the screw, that is, the lower die cavity. The lower end of the upper die is provided with cylindrical pits. The top is provided with hexagonal prism protrusions, and the cavity between the cylindrical recess and the hexagonal prism protrusions constitutes an upper die cavity that matches the shape of the head of the hexagon socket head screw, and the centerlines of the upper and lower die cavities coincide. Fix the lower mold, and put a round rod into the lower mold cavity. The length of the round rod is greater than the height of the lower mold cavity, and the upper mold and the punch are fixed. Drive the punch to make the ...
