Description

Technical Field

[0001] The utility model relates to the technical field of punch press blanking, and specifically relates to a punch press blanking sorting device. Background Art

[0002] A punch press is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to make products that cannot be achieved by mechanical processing through various mold applications compared to traditional mechanical processing. Therefore, its use is becoming more and more extensive. After the lathe processes the workpiece, it is necessary to collect and sort the processed workpiece. Generally, the collection device is set at the lower hopper of the punch press for collection. However, when the collection device is full of processed workpieces, a new collection device needs to be replaced at the lower hopper. However, the punch press is generally continuously produced and processed during use, so the workpieces at the lower hopper are also continuously unloaded. If the punch press is stopped to replace the collection device, it will have a certain impact on the overall processing efficiency of the punch press. If the punch press is not stopped, the lower hopper that continuously unloads will cause some workpieces to fall when the collection device is replaced, and people need to collect the scattered workpieces again, which reduces the overall unloading and collection efficiency of the punch press.

[0003] After searching, China disclosed a punch press material unloading and sorting device with patent publication number CN220295714U on January 5, 2024. It is roughly described as including a punch press body, a material unloading hopper is arranged in the middle of one side of the punch press body, a fixed groove is opened in the middle of the bottom end of the inner wall of the lower hopper, and a unloading hole is opened through the bottom end of the inner wall of the fixed groove. A movable baffle is rotatably installed on the edge of one side of the inner wall of the fixed groove, and a limiting card slot is symmetrically opened on one side of the movable baffle. A placement slot is opened in the middle of the front and rear ends of the material unloading hopper, and a limiting baffle is movably installed inside the placement slot, and a material blocking mechanism is also provided at the bottom of the fixed slot.

[0004] Although the above-mentioned prior art solution solves the problem that the workpieces fall along the lower hopper and are inconvenient to collect due to the replacement of the collection device, thereby improving the overall processing efficiency of the punching machine body, the device requires manual control when opening and closing the control baffle, so it is easy for the hands to be injured by the continuously falling workpieces, resulting in low safety of the equipment.
