[0032] When the above scheme is put into actual use, the raw material to be stamped is placed from above the upper clamping part 7 into the clamping part 7, and the bottom end of the raw material is inserted into the lower clamping part 7, and then the first driving component is started to drive the mold 2 to move to the side close to the raw material, and the two molds 2 will cooperate to stamp the raw material. After stamping and forming, the first driving component will drive the mold 2 to move outward; the stamped parts will also be between the two clamping parts; the mold 2 will drive the second driving component to work while moving, and the second driving component will drive the first slider 4 and the fixed block 6 to move downward synchronously, the fixed block 6 will drive the two clamping parts 7 to move downward synchronously, and the clamping part 7 will drive the formed parts to move downward synchronously. When the bottom end of the part contacts the conveying component, the second driving component will The first slide is driven to drive the clamping part 7 below to move to the side away from the part, so that the clamping part 7 below slowly disengages from the clamping of the part, and then the part will fall onto the conveying assembly, and then the conveying assembly can convey the part to the collection position; the present invention arranges the clamping part 7, the second driving assembly and the conveying assembly, so that the formed part can be clamped by the clamping part 7, which can avoid the part from falling directly and causing damage to the part. At the same time, during the process of the mold 2 moving outward, the second driving assembly can drive the clamping part 7 to drive the part to move downward, until the part moves to contact with the conveying assembly, and the clamping part 7 below will move outward and disengage from the part, so that the part can fall stably onto the conveying assembly, which can avoid the part from falling and better ensure the quality of the part.

[0033] As a further solution of the present invention, the second driving assembly includes a first traction rope 10 and a second traction rope 11; one end of the first traction rope 10 is fixedly connected to the first slider 4, the other end of the first traction rope 10 passes through the top of the base plate 1 and is fixedly connected to a winding roller 12, the winding roller 12 is rotatably connected to the base plate 1, and a first gear 13 is fixedly connected to the rotating shaft of the winding roller 12, the first gear 13 is connected to the second gear 14 through a speed change assembly, the second gear 14 is rotatably connected to the base plate 1, the second gear 14 is meshed with a first rack rod 15, and the first rack rod 15 is connected to the mold 2; one end of the second traction rope 11 is fixedly connected to the first slide plate 8, the other end of the second traction rope 11 passes through the side wall of the fixed block 6 and is fixedly connected to an arc-shaped slide plate 16, the arc-shaped slide plate 16 is rotatably connected to the fixed block 6, the arc-shaped slide plate 16 is fixedly connected to a slide bar 17, and the slide bar 17 is slidably connected to the first mounting plate 3.

The first gear 13 will drive the winding roller 12 to rotate synchronously. The winding roller 12 will wind up the first traction rope 10. The first traction rope 10 will drive the first slider 4 to move downward. The first slider 4 will drive the fixed block 6 to move downward synchronously. The fixed block 6 will drive the arc-shaped slide plate 16 to move downward synchronously. The arc-shaped slide plate 16 will drive the slide bar 17 to slide downward on the first mounting plate 3. When the bottom end of the part contacts the conveying component, the part will drive the fixed block 6 to rotate around the first slider 4. At this time, the arc-shaped slide plate 16 will be fixed relative to the fixed block 6. When the fixed block 6 drives the lower clamping part 7 and the first slide plate 8 to rotate synchronously, the second traction rope 11 will pull the first slide plate 8 to move towards the side close to the fixed block 6. The first slide plate 8 will drive the clamping part 7 to move synchronously. The clamping part 7 will slowly separate from the part, and then the part can fall onto the conveying component.

[0035] As a further solution of the present invention, the speed-changing component includes a third gear 18.

The fifth gear 20 will drive the fourth gear 19 to rotate. The fourth gear 19 will drive the third gear 18 to rotate. The third gear 18 will drive the first gear 13 to rotate.

[0037] As a further solution of the present invention, the first driving assembly includes a cylinder 21 and a second mounting plate 22; the fixed end of the cylinder 21 is rotatably connected with a mounting block 23, the mounting block 23 is fixedly connected to the base plate 1, the output end of the cylinder 21 is rotatably connected to the mold 2, the second mounting plate 22 is fixedly connected to the base plate 1, and the second mounting plate 22 is provided with a first slide groove 24 and a second slide groove 25, the second slide groove 25 is composed of a transverse groove 251 and an arc groove 252, the transverse groove 251 is connected to the arc groove 252, the first slide groove 24 and the second slide groove 25 are respectively movably connected with a first slide column 26 and a second slide column 27, the first slide column 26 and the second slide column 27 are respectively fixedly connected to the top and bottom ends of the mold 2; the first rack rod 15 is rotatably connected to the first slide column 26, and the first rack rod 15 is slidably connected to the second mounting plate 22.

[0038] When the first driving assembly is actually working, during stamping, the cylinder 21 drives the mold 2 to move toward the side close to the raw material, and the mold 2 drives the first slide post 26 and the second slide post 27 to move synchronously. The second slide post 27 moves first into the transverse groove 251 in the circular arc groove 252. At this time, the mold is in a vertical state, and then the cylinder 21 pushes the mold 2 to move horizontally. The first slide post 26 and the second slide post 27 slide in the first slide groove 24 and the transverse groove 251 respectively. By setting the first slide groove 24 and the second slide groove 25, the mold can be in a state such as Figure 2 The tilted state shown can make the debris left on the die due to stamping fall off automatically. At the same time, the trapezoidal shape of the two dies, which is small at the top and large at the bottom, can also leave enough space for the parts to move downward.

[0039] As a further solution of the present invention, the conveying assembly includes a third mounting plate 40, a first belt roller 28, a second belt roller 29 and a conveyor belt 30; the third mounting plate 40 is fixedly connected to the base plate 1, the first belt roller 28 and the second belt roller 29 are installed on the third mounting plate 40, and the conveyor belt 30 is transmission-connected to the first belt roller 28 and the second belt roller 29.

[0040] A second slider 31 is rotatably connected to the second belt roller 29. The second slider 31 is slidably connected to the third mounting plate 40. A third spring 32 for resetting it is fixedly connected to the second slider 31. The third mounting plate 40 is slidably connected to a third slider 33 in the vertical direction. A third belt roller 34 is rotatably connected to the third slider 33. The third belt roller 34 is in transmission connection with the conveyor belt 30. A third traction rope 35 is fixedly connected to the third slider 33. The top end of the third traction rope 35 passes through the side wall of the bottom plate 1 and is fixedly connected to a second rack bar 36. The second rack bar 36 is slidably connected to the bottom plate 1. The second rack bar 36 meshes with a sixth gear 37. The sixth gear 37 is rotatably connected to the bottom plate 1. The sixth gear 37 is in transmission connection with a seventh gear 39 through a chain 38. The seventh gear 39 is fixedly connected to the rotating shaft of the winding roller 12.

[0041] When the above solution is put into actual use, as Figure 2 and Figure 8 shown, when the winding roller 12 rotates, it will drive the sixth gear 37 to rotate synchronously through the seventh gear 39 and the chain 38. The sixth gear 37 will drive the second rack bar 36 to move to the left. The second rack bar 36 will drive the third slider 33 to slide upward through the third traction rope 35. The third slider 33 will drive the third belt roller 34 to move upward synchronously. At this time, the third belt roller 34 will drive the top of the conveyor belt 30 to move upward synchronously. The conveyor belt 30 will drive the second belt roller 29 and the second slider 31 to move to the side close to the third belt roller 34. The second slider 31 will stretch the third spring 32. At this time, the conveyor belt 30 is in a triangular shape. After the bottom end of the part contacts the inclined surface of the triangular conveyor belt 30, it will slide down obliquely along the conveyor belt 30. At this time, the fixed block 6 will rotate, and then the lower clamping part 7 will move away from the part. Then the part can slide down the inclined surface of the conveyor belt 30 and completely slide onto the conveyor belt 30. Through the settings of the third belt roller 34, the third slider 33, the third traction rope 35, the second rack bar 36, the sixth gear 37, the chain 38 and the seventh gear 39, the present invention can make the third traction rope 35 drive the third slider 33 and the third belt roller 34 to move upward when the clamping part 7 drives the formed part to move downward, so that the conveyor belt 30 presents a triangular shape. Then, after the part contacts the inclined surface of the conveyor belt 30, it will slide obliquely downward. While the bottom end of the part moves downward along the conveyor belt 30, the fixed block 6 will rotate under the action of the part. The fixed block 6 can drive the part to be close to the conveyor belt 30, which can better ensure that the part will not fall on the conveyor belt and cause defects. During the stamping process, when the conveyor belt 30 is in a horizontal state, the conveyor belt 30 can be in a non-tight state, which can increase the service life of the conveyor belt 30.

[0043] Step 1: Place the raw material (metal plate) between the clamping parts 7 from above the clamping parts 7 and adjust the position of the raw material.

[0044] Step 2: Then start the first driving component to drive the die 2 to stamp the raw material.

[0045] Step 3: After stamping is completed, make the first driving component drive the die 2 to move back to the initial position, and then the first driving component will drive the clamping parts 7 and the stamped part to move downward through the second driving component.

[0046] Step 4: After the part falls onto the conveying component, the conveying component will convey the part to the collection position.

[0047] Working principle: Place the raw material to be stamped between the upper clamping parts 7 from above the upper clamping parts 7, and make the bottom end of the raw material snap into the lower clamping parts 7. Then start the first driving component to drive the die 2 to move towards the side close to the raw material. The two dies 2 will cooperate to stamp the raw material into shape. After stamping is completed, make the first driving component drive the die 2 to move outward; the stamped part will still be between the two clamping parts; while the die 2 is moving, it will drive the second driving component to work. The second driving component will drive the first slider 4 and the fixed block 6 to move downward synchronously. The fixed block 6 will drive the two clamping parts 7 to move downward synchronously. The clamping parts 7 will drive the formed part to move downward synchronously. When the bottom end of the part contacts the conveying component, the second driving component will drive the first sliding plate to drive the lower clamping part 7 to move away from the part, so that the lower clamping part 7 slowly disengages from clamping the part. Then the part will fall onto the conveying component, and then the conveying component can convey the part to the collection position; through the settings of the clamping parts 7, the second driving component and the conveying component, the formed part can be clamped by the clamping parts 7, which can avoid damage to the part caused by the direct fall of the part. At the same time, during the process of the die 2 moving outward, the second driving component can drive the clamping parts 7 to drive the part to move downward until the part moves to contact the conveying component and then the lower clamping part 7 will move outward to disengage from the part, which can make the part fall stably onto the conveying component and can avoid the situation of the part being smashed down, and can better ensure the quality of the part.
