[0025] As an implementation method in this embodiment, Figure 2 , Figure 3 and Figure 4As shown, the pushing assembly includes a push rod 7, the top end of the push rod 7 is inserted into the pushing groove 501, the bottom end of the push rod 7 is located at the top end of the moving slider 602, the outer end of the push rod 7 is fixedly connected to the limiting block 702, the outer side of the push rod 7 is sleeved with a spring 701, the bottom end of the spring 701 is fixedly connected to the inner top end of the lower die base 1, the positioning mechanism includes a first connecting rod 8, the first connecting rod 8 is fixedly connected to the side end of one group of moving sliders 602, the side end of the first connecting rod 8 is fixedly connected to the second connecting rod 801, the second connecting rod 801 penetrates into the interior of the mounting groove 504, the side end of the second connecting rod 801 is fixedly connected to the moving block 802, the side end of the moving block 802 is fixedly connected to the positioning pin 803, so that the positioning pin 803 can be moved to the left to position the workpiece 4, the inner side end of the mounting groove 504 is fixedly connected to the guide rail 804, the moving block 802 is slidably connected to the side end of the guide rail 804, and the moving block 802 can slide left and right through the guide rail 804.

[0026] During implementation, when the electric push rod 601 retracts and pulls the movable slider 602 to move to the left, it drives the push rod 7 and the limit block 702 to move downward along the arc setting on the top of the movable slider 602. At this time, the spring 701 drives the push rod 7 to move down and reset. At the same time, when the movable slider 602 moves to the left, it drives the first connecting rod 8 and the second connecting rod 801 to move to the left. At this time, the movable block 802 is driven to slide to the left on the side end of the guide rail 804. The movable block 802 drives the positioning pin 803 to move to the left, so that the positioning pin 803 presses the lower end of the workpiece 4 against the limit groove 503, thereby positioning the workpiece 4, effectively avoiding the accuracy deviation of the finished product due to strong vibration, and reducing the production cost.

At this time, the pressure spring 701 contracts, so that the ejector rod 7 is inserted through the ejection groove 501, and the top end of the ejector rod 7 is pressed against the bottom end of the workpiece 4 to eject it to complete the discharge, thereby removing the workpiece 4, avoiding the bending part from sticking to the mold, causing difficulty in discharging the workpiece 4, and improving work efficiency.

[0028] As an implementation method in this embodiment, Figure 1 and Figure 5As shown, the bending assembly includes a fixed pad 2, which is fixedly connected to the bottom end of the upper die base 102, and a plurality of support columns 201 are fixedly connected to the bottom end of the fixed pad 2. A bending pressing plate 202 is fixedly connected between the bottom ends of the plurality of support columns 201. A punching hole 203 is provided at the top of the bending pressing plate 202. A punch 301 is fixedly installed at the top of the upper die base 102. A punch 301 is installed at the bottom end of the punch 3. A waste groove 103 is provided on the outer side of the lower die base 1. A drawer 9 is slidably connected to the waste groove 103. Since the upper die base 102 and the bending pressing plate 202 are fixedly connected through the support columns 201, when the cylinder 101 is started to drive the upper die base 1 02 moves downward, and the bending pressing plate 202 also moves downward, at this time driving the punching machine 3 to move downward as well, and the punching machine 3 drives the punch 301 to move downward through the punching hole 203, and the cylinder 101 drives the bending pressing plate 202 to press the workpiece 4 against the top 5 of the edge bending block, and the punch 301 presses the workpiece 4 and moves downward into the stamping groove 502, so that the workpiece 4 can be stamped and bent. After the workpiece 4 is stamped and bent, the cylinder 101 drives the upper die seat 102 and the bending pressing plate 202 to reset, and the punching machine 3 drives the punch 301 to move upward, and the waste generated by the punch 301 stamping the workpiece 4 falls into the drawer 9 through the waste slot 103, and the operator can open the drawer 9 to pour out the waste.

[0029] Working principle: Place the workpiece 4 on the top of the edge bending block 5, and the lower end of the workpiece 4 is inserted into the limit groove 503. When the electric push rod 601 retracts and pulls the moving slider 602 to move to the left, it drives the push rod 7 and the limit block 702 to move downward along the arc setting on the top of the moving slider 602. At this time, the spring 701 drives the push rod 7 to move down and reset. At the same time, when the moving slider 602 moves to the left, it drives the first connecting rod 8 and the second connecting rod 801 to move to the left. At this time, it drives the moving block 802 to slide left on the guide rail 804. The moving block 802 drives the positioning pin 803 to move to the left, so that the positioning pin 803 presses the lower end of the workpiece 4 into the limiting groove 503 to position the workpiece 4, effectively avoiding the deviation of the precision of the finished product caused by strong vibration, and reducing the production cost. When the cylinder 101 is started to drive the bending pressing plate 202 and the punch 3 to move downward to press the workpiece 4 against the top 5 of the edge bending block, the punch 301 presses the workpiece 4 and moves downward into the stamping groove 502, so that the workpiece 4 can be stamped and bent. After the workpiece 4 is stamped and bent, the cylinder 101 drives the upper die seat 102 and the bending press plate 202 to reset. When the electric push rod 601 is extended, the movable slide block 602 is pushed to move to the right, driving the first connecting rod 8 and the second connecting rod 801 to move to the right. At this time, the second connecting rod 801 drives the movable block 802 to slide to the right on the side end of the guide rail 804, and the movable block 802 drives the positioning pin 803 to move to the right, so that the positioning pin 803 is away from the lower end of the workpiece 4, so that the workpiece 4 is out of position. At the same time, the movable slide block 602 moves to the right. The push rod 7 and the limit block 702 are driven to move upward along the arc setting on the top of the movable slider 602. At this time, the pressure spring 701 contracts, allowing the push rod 7 to pass through the ejection groove 501, and the top of the push rod 7 is pressed against the bottom end of the workpiece 4 to eject it to complete the discharge, thereby removing the workpiece 4, avoiding the bending part from sticking to the mold, causing difficulty in discharging the workpiece 4, and improving work efficiency. The waste generated by stamping the workpiece 4 falls into the drawer 9 through the waste slot 103, and the operator can open the drawer 9 to pour out the waste.
