Abstract
Description
Technical Field
[0001] The utility model relates to the field of stamping dies, and particularly relates to a workpiece taking mechanism for a stamping and stretching die. Background Technique
[0002] At present, with the rapid development of the automobile manufacturing industry, the types and structures of dies are becoming more and more complex. At present, the die positioning method mostly uses the surface positioning. However, the surface positioning often causes the formed parts to adhere to the lower die, and workers still need to forcefully remove them, which is likely to cause difficulties for operators to take the parts and lead to low work efficiency. In addition, at present, many programmed stamping dies work at a fixed frequency. With the progress of technology, the workpiece taking mostly relies on the manipulator to automatically unload the material.
[0003] When the existing workpiece taking mechanism takes the material, most of them need to wait for a certain distance between the upper die and the lower die to separate before taking the workpiece. The waiting process wastes a lot of time, affects the subsequent feeding steps, and thus affects the work efficiency and production capacity. Further improvement is needed. For this reason, a workpiece taking mechanism for a stamping and stretching die is proposed. Content of the Utility Model
[0004] The main purpose of the utility model is to provide a workpiece taking mechanism for a stamping and stretching die, which can effectively solve the problems in the background technique.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A workpiece taking mechanism for a stamping and stretching die includes a workbench. A lower die is installed in the middle of the upper end of the workbench. An L-shaped plate is installed at the rear of the upper end of the workbench. A stamping groove is opened at the upper end of the lower die. A blank holding component is installed on the inner wall of the lower die. A concave plate is arranged behind the stamping groove. A hydraulic cylinder is installed at the upper end of the L-shaped plate. The output end of the hydraulic cylinder movably penetrates through the L-shaped plate and is installed with an upper die. After stamping is completed, the blank holding component pushes the workpiece away from the stamping groove, and then the concave plate pushes the workpiece forward.
[0007] Preferably, an L-shaped frame is installed at the rear end of the lower die. A cylinder is installed at the upper end of the L-shaped frame. The output end of the cylinder is fixedly connected to the rear end of the concave plate.
[0008] Preferably, the blank holding component includes springs. There are several springs. All the springs are installed on the lower inner wall of the lower die. A transverse plate is jointly installed at the upper ends of the several springs. Several ejector pins are installed at the upper end of the transverse plate. The ejector pins movably penetrate into the stamping groove.
[0009] Preferably, an electric cylinder is installed at the lower end of the workbench, a through groove is formed at the lower end of the lower die, and the output end of the electric cylinder extends into the through groove.
[0010] Preferably, a sliding plate is installed at the front end of the lower die, a U-shaped plate is jointly installed at the left and right ends of the sliding plate, and a plurality of rubber strips are installed on the upper inner wall of the U-shaped plate and are distributed in a linear array.
[0011] Preferably, a collection box is installed at the front part of the upper end of the workbench, and the front end of the sliding plate extends into the collection box.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. By setting the concave plate, the air cylinder, the material positioning component and the electric cylinder to cooperate with each other, the unloading efficiency can be improved. After stamping is completed, when the upper die and the lower die are separated, control the output end of the electric cylinder to extend and push the cross plate upward. The cross plate drives the ejector pin upward, and the ejector pin pushes the stamped workpiece above the stamping groove. Then control the output end of the air cylinder to drive the concave plate forward, and the concave plate pushes the workpiece away from above the ejector pin. Due to inertia, the workpiece moves forward, and the unloading can be completed during the separation of the upper die and the lower die, reducing the waste of time, improving the work efficiency and production capacity, and facilitating subsequent rapid feeding;
[0014] 2. By setting the U-shaped plate, the sliding plate and the rubber strips to cooperate with each other, the moving direction of the workpiece can be guided. When the workpiece flies away from the ejector pin and moves forward, the rubber strips can block the workpiece. The blocking of the rubber strips can accurately control the movement path of the workpiece, avoid the workpiece flying in an uncertain direction due to inertia, improve the accuracy of workpiece collection, make the workpiece fall above the sliding plate and slide into the collection box, reduce the workload of manual intervention and sorting, and improve the efficiency of the overall production line.

[0024] As Figures 1-4As shown in the figure, a workpiece taking mechanism for a stamping and stretching die includes a workbench 1. In the middle of the upper end of the workbench 1, a lower die 4 is installed. At the rear of the upper end of the workbench 1, an L-shaped plate 7 is installed. A stamping groove 14 is opened at the upper end of the lower die 4. A blank holding component 13 is installed on the inner wall of the lower die 4. At the upper end of the L-shaped plate 7, a hydraulic cylinder 8 is installed. The output end of the hydraulic cylinder 8 movably penetrates through the L-shaped plate 7 and is installed with an upper die 9. The upper die 9 is located above the lower die 4. During use, the plate to be stamped is placed into the stamping groove 14. Control the output end of the hydraulic cylinder 8 to drive the upper die 9 to move downward so that the upper die 9 contacts the lower die 4, and stamping can be completed. After stamping, control the output end of the hydraulic cylinder 8 to drive the upper die 9 away from the lower die 4. After leaving a certain distance, the blank holding component 13 pushes the workpiece upward so that the workpiece moves away from the stamping groove 14. Finally, the stamped workpiece is taken out by a manipulator. However, during the process when the manipulator waits for the upper die 9 and the lower die 4 to separate, a lot of time is wasted, which affects the subsequent feeding steps.
[0025] In order to improve the above situation, through the joint cooperation of the concave plate 12, the air cylinder 11, the blank holding component 13 and the electric cylinder 2, the workpiece can be taken out during the process of the separation of the upper die 9 and the lower die 4. For this reason, a concave plate 12 is arranged behind the stamping groove 14. The concave plate 12 is of a concave structure to avoid the center ejector pin 131. At the rear end of the lower die 4, an L-shaped frame 10 is installed. At the upper end of the L-shaped frame 10, an air cylinder 11 is installed. The output end of the air cylinder 11 is fixedly connected to the rear end of the concave plate 12 by bolts. The blank holding component 13 includes a spring 133. A plurality of springs 133 are provided. A plurality of springs 133 are all installed on the lower inner wall of the lower die 4. A cross plate 132 is jointly installed at the upper ends of the plurality of springs 133. A plurality of ejector pins 131 are installed at the upper end of the cross plate 132. The spring 133 is used to drive the ejector pin 131 to reset. The ejector pin 131 movably penetrates into the stamping groove 14. An electric cylinder 2 is installed at the lower end of the workbench 1. A through groove 5 is opened at the lower end of the lower die 4. The output end of the electric cylinder 2 extends into the through groove 5. After stamping, during the time when the upper die 9 and the lower die 4 are separated, control the output end of the electric cylinder 2 to extend and push the cross plate 132 upward. The cross plate 132 drives the ejector pin 131 to move upward. The ejector pin 131 pushes the stamped workpiece above the stamping groove 14. Then control the output end of the air cylinder 11 to quickly drive the concave plate 12 to move forward. The concave plate 12 pushes the workpiece away from above the ejector pin 131. Due to inertia, the workpiece moves forward, and unloading can be completed during the separation of the upper die 9 and the lower die 4, reducing the waste of time, improving the work efficiency and production capacity, and facilitating subsequent rapid feeding. After unloading, control the output end of the electric cylinder 2 to reset, and control the output end of the air cylinder 11 to drive the concave plate 12 to move backward.
[0026] In addition, when the workpiece after stamping is pushed forward by the concave plate 12, it is necessary to slow down the forward movement speed of the workpiece and make the workpiece accurately fall into the collection box 3 to prevent the workpiece from flying in an uncertain direction due to inertia. Therefore, a slide plate 6 is installed at the front end of the lower die 4. The slide plate 6 is of a concave structure. A U-shaped plate 15 is jointly installed at the left end and the right end of the slide plate 6. A plurality of rubber strips 16 distributed in a linear array are installed on the upper inner wall of the U-shaped plate 15. The rubber strips 16 have a certain weight to facilitate offsetting the inertia of the forward movement of the workpiece. When the workpiece flies forward above the ejector pin 131, the rubber strips 16 can block the workpiece. The blocking of the rubber strips 16 can accurately control the movement path of the workpiece, prevent the workpiece from flying in an uncertain direction due to inertia, improve the accuracy of workpiece collection, make the workpiece fall above the slide plate 6 and slide into the collection box 3, reduce the workload of manual intervention and sorting, and improve the efficiency of the overall production line.
[0027] To collect the workpiece, a collection box 3 is installed at the front part of the upper end of the workbench 1, and the front end of the slide plate 6 extends into the collection box 3.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
