The invention discloses a feeding and discharging device for a punching process. The feeding and discharging device comprises a clamp bottom plate, a pull rod making reciprocating movement, a first connecting rod hinged with the pull rod, and a second connecting rod hinged with the first connecting rod, wherein the pull rod is connected onto the clamp bottom plat through a first pushing column to form a first fulcrum, and a feeding top block is arranged at the end of the pull rod; the second connecting rod is connected onto the clamp bottom plate through a second pushing column to form a second fulcrum, and a discharging pushing block is arranged at the end of the second connecting rod; and an adaptive feeding pushing block, a discharging pushing block and a positioning block for placing a punching workpiece are arranged on the clamp bottom plate. The reciprocating movement of the pull rod on the same horizontal plane meets the requirements of feeding and discharging in the punching process, accordingly, the production efficiency is improved, the safety of production is ensured, the structure is simple, the manufacturing cost is low, and the requirements of actual production are better met.
Description
technical field [0001] The invention relates to a feeding and retracting device, in particular to a feeding and retracting device used in a punching process. Background technique [0002] In the traditional punching process, the operators are completely free-handed. This method is labor-intensive and low in production efficiency. Moreover, due to the large force at the moment of punching, if the positioning is not accurate, the safety of employees is often difficult to obtain. ensure. [0003] The Chinese patent discloses a utility model patent with the announcement number of "CN 202180151U" and the name is "linked material feeding and withdrawing device". It is connected with the punch conveyor belt and the lower die of the punch press; the feeding plate and the feeding plate are arranged at the upper part of the feeding channel, and the feeding plate is arranged at the lower part of the feeding channel, and The length of the feeding plate is greater than the length of th...
