[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] Example: Figures 1-3As shown in the figure, the utility model provides a hot stamping and drawing die, which includes a support table 1. At the top edge of the support table 1, an L-shaped frame 11 is fixedly installed. The top of the L-shaped frame 11 is fixedly penetrated by a cylinder 12. The driving end of the cylinder 12 is fixedly installed with a first moving plate 13. The bottom of the first moving plate 13 is provided with an upper die 14. On the upper surface of the support table 1, there is a turntable 15. At the top of the turntable 15, a number of lower die assemblies 16 evenly distributed in a ring are fixedly installed. At the bottom of the support table 1, a U-shaped frame 2 is fixedly installed. The bottom of the U-shaped frame 2 is rotatably penetrated by a first rotating shaft 21. The first rotating shaft 21 is rotatably clamped on the support table 1. On the outside of the first rotating shaft 21, a half-face gear 22 is fixedly installed. At the bottom of the turntable 15, a second rotating shaft 23 is fixedly installed. The second rotating shaft 23 is rotatably penetrated by the support table 1. On the outside of the second rotating shaft 23, a gear 24 that cooperates with the half-face gear 22 is fixedly installed. The second rotating shaft 23 is rotatably clamped on the U-shaped frame 2.
[0016] On one side of the top of the support table 1 away from the turntable 15, a fixed block 30 is fixedly installed. The top of the fixed block 30 is fixedly penetrated by a hydraulic telescopic rod 3. The driving end of the hydraulic telescopic rod 3 is fixedly installed with a second moving plate 31. At the top of the second moving plate 31, two symmetrically distributed fixed seats 32 are fixedly installed. The fixed seats 32 are fixed at the edge of the second moving plate 31. The top of the fixed seat 32 is rotatably penetrated by a double-headed screw 33 with opposite threads at both ends. On the outside of the double-headed screw 33, two symmetrically distributed clamping plates 34 are threadedly connected.
[0017] At the top of the fixed seat 32, a limiting rod 4 is fixedly installed. The two clamping plates 34 are slidably sleeved on the outside of the limiting rod 4. By setting the limiting rod 4, the clamping plates 34 are limited to prevent the clamping plates 34 from rotating with the rotation of the double-headed screw 33, which affects the clamping of the drawn parts by the clamping plates 34.
[0018] At the bottom of the second moving plate 31, two symmetrically distributed sliders 5 are fixedly installed. The sliders 5 are located at the edge of the second moving plate 31. At the position of the second moving plate 31 on the top of the support table 1, a chute 51 that cooperates with the sliders 5 is opened. By setting the sliders 5 and the chute 51, when the second moving plate 31 moves, it is more stable. At the same time, when the sliders 5 move from one side of the inner wall of the chute 51 to the other side of the inner wall of the chute 51, it means that the second moving plate 31 cannot move anymore, and at this time, the clamping plates 34 are exactly at the position where they can clamp the drawn parts.
[0019] At the top of the support table 1, an empty slot 7 is penetrated below the clamping plates 34. By setting the empty slot 7, a collection box is placed below the empty slot 7, and then through the clamping and loosening of the clamping plates 34, the drawn parts fall into the collection box from the empty slot 7, so as to collect the drawn parts.
[0020] At the bottom end of the support table 1, an L-shaped plate 8 is fixedly installed at the edge of the empty slot 7. By setting the L-shaped plate 8, when it is necessary to place the receiving box below the empty slot 7, the outer wall of the receiving box is attached to the L-shaped plate 8, and then pushed forward to make the collection box located below the empty slot 7, so as to facilitate the alignment of the collection box with the empty slot 7.
[0021] At the bottom end of the U-shaped frame 2, a first motor 25 is fixedly installed. The driving end of the first motor 25 is fixedly installed at the end of the first rotating shaft 21. By setting the first motor 25, when the first motor 25 is started, it drives the first rotating shaft 21 to rotate, thereby driving the half-face gear 22 to rotate.
[0022] On one side of one of the fixed seats 32, a second motor 35 is fixedly installed. The driving end of the second motor 35 is fixedly installed at the end of the double-headed screw 33. By setting the second motor 35, when the second motor 35 is started, it drives the double-headed screw 33 to rotate, thereby driving the two clamping plates 34 to move towards the middle or move towards both sides.
[0023] Working principle: During actual use, the collection box is placed below the empty slot 7, and then the heated parts are placed on the lower die assembly 16 opposite the L-shaped frame 11 and on the lower die assembly 16 opposite the clamping plates 34 through other fixtures. Subsequently, by starting the first motor 25, the first rotating shaft 21 and the half-face gear 22 are driven to rotate, so that the half-face gear 22 meshes with the gear 24, thereby driving the second rotating shaft 23, the turntable 15, and the lower die assembly 16 on the turntable 15 to rotate. When the lower die assembly 16 opposite the clamping plates 34 and the heated parts are located below the upper die 14, exactly the half-face gear 22 is not meshed with the gear 24. Subsequently, the air cylinder 12 is started to drive the first moving plate 13 and the upper die 14 to move downward to draw the heated parts. When the drawing is completed, exactly the half-face gear 22 meshes with the gear 24 again, causing the turntable 15 and the lower die assembly 16 to rotate;
[0024] Then when the drawn parts are located at the position of the clamping plates 34, exactly the half-face gear 22 is not meshed with the gear 24. At this time, the hydraulic telescopic rod 3 is started to drive the second moving plate 31 to move towards the drawn parts. When it moves to the position where it can clamp the drawn parts, the second motor 35 is started to drive the double-headed screw 33 to rotate, thereby driving the two clamping plates 34 to move towards the middle to clamp the drawn parts. After clamping, the second motor 35 is turned off, and the hydraulic telescopic rod 3 is started again to make the second moving plate 31, the components on the second moving plate 31, and the clamped drawn parts move in the opposite direction of the turntable 15. Subsequently, the second motor 35 is started to drive the double-headed screw 33 to rotate in the reverse direction, not clamping the drawn parts, so that the drawn parts fall from below the empty slot 7 into the collection box. While clamping the drawn parts, exactly the next part to be drawn is located below the upper die 14 for drawing;
[0025] Subsequently, the gears 24 and the half-face gear 22 mesh again, causing the turntable 15 to rotate again. Then, when the lower die assembly 16 without parts is exactly opposite the L-shaped frame 11, the gears 24 and the half-face gear 22 are disengaged. Then, the heated parts are placed on the lower die assembly 16 without parts. At the same time, the second moving plate 31 is moved, and the clamping plate 34 clamps the drawn parts, and the operation is repeated.
[0026] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
