Auto parts stamping is a process for manufacturing auto parts. By using stamping dies and stamping machines, metal sheets are processed into the required shape and size.

[0003] In the current automobile parts stamping equipment and technology, a punch is used to punch onto a die, and the metal sheet is stamped and formed by extrusion. In this process, the loading and unloading of the metal sheet is carried out by a suction cup robot arm, and suction cup robot arms are equipped on both sides of the stamping equipment. The suction cup robot arms on both sides respectively load and unload the metal sheet. The metal sheet needs to be adsorbed by the suction cup during loading and unloading. Since the loading and unloading structure of the suction cup robot arm is an external device of the stamping equipment and is not integrated with the stamping die, the suction cup robot arm occupies a large space on both sides of the stamping die, which will directly lead to a reduction in the available space in the production workshop. At the same time, after each stamping is completed, the stamping equipment needs to pause to reserve time for the suction cup robot arm to load and unload, resulting in problems such as extended stamping time and reduced stamping efficiency.

The push-pull assembly 10 includes a U-shaped movable plate 101 connected to the top right side of the lifting plate 3, and the U-shaped movable plate 101 is slidably connected to the outer wall of the mounting frame 7 through a slide groove. The front and rear sides of the U-shaped movable plate 101 are hinged with connecting plates 102, and a push-pull rod 103 is rotatably connected between the lower parts of the two connecting plates 102. The push-pull rod 103 is fixedly connected to the push plate 9, and a telescopic rod 11 is installed at the bottom of the workbench 1, and a telescopic rod 11 is connected to the telescopic rod 11 for moving the inner surface of the die 6 The ejector frame 12 for ejecting the stamped parts includes a connecting block 121 connected to the telescopic rod 11, and two U-shaped connecting rods 122 are symmetrically connected to the connecting block 121 in the front and rear directions. The top of the U-shaped connecting rod 122 on the rear side is connected to a U-shaped ejector rod I 123, and the U-shaped ejector rod I 123 passes through the workbench 1 and the die 6. The U-shaped connecting rod 122 on the front side is slidably connected to a U-shaped ejector rod II 124 that can move up and down, and the U-shaped ejector rod II 124 passes through the workbench 1 and the die 6. The U-shaped connecting rod 122 on the front side is symmetrically sleeved with two compression springs 125, and the compression springs 125 are in contact with the U-shaped connecting rod 122 and the U-shaped ejector rod II 124 on the front side. The inner top of the workbench 1 is connected to a limiting block 126, and the U-shaped ejector rod II 124 can move upward with the limiting block 126. The lifting plate 3 moves downward and contacts the contact plate 142. A tension spring 143 is connected between the contact plate 142 and the L-shaped pull plate 141. A push plate 15 is connected to the left side of the top of the frame 2. The push plate 15 is located above the contact plate 142. The contact plate 142 moves upward and contacts the push plate 142. The top of the contact plate 142 is an inclined surface. A positioning component 16 for positioning the metal sheet is provided on the die 6.The positioning assembly 16 includes a guide rod 161, a positioning block 162 and a support spring 163. The left and right sides and the front and rear sides of the die 6 are slidably connected with positioning blocks 162 that can move up and down. The bottom of the positioning block 162 passes through the top of the workbench 1. The lower part of the positioning block 162 is slidably connected with the guide rod 161. The guide rod 161 is fixedly connected to the inner top of the workbench 1. The guide rod 161 is sleeved with a support spring 163. The support spring 163 is connected to the guide rod 161 and the positioning block 162. The sides of the left and right positioning blocks 162 facing away from each other and the sides of the front and rear positioning blocks 162 facing away from each other are all inclined surfaces.

[0027] The metal sheet to be stamped is placed in the storage frame 8, and the metal sheet then falls into the receiving groove 91 on the push plate 9. The hydraulic cylinder 4 is controlled to drive the lifting plate 3 to move up and down. The up and down reciprocating movement of the lifting plate 3 drives the U-shaped movable plate 101 to move up and down. The U-shaped movable plate 101 moves up and pulls the push-pull rod 103 to the left through the connecting plate 102, thereby causing the push plate 9 to move left through its upper receiving groove 91 to push the metal sheet to the die 6 to realize automatic loading. Since the depth of the receiving groove 91 on the push plate 9 is smaller than the metal sheet The thickness of the metal sheet, the height difference between the bottom of the storage frame 8 and the ungrooved position of the top of the push plate 9 is less than the thickness of the metal sheet, and the depth of the discharge port 71 on the mounting frame 7 is greater than the thickness of the metal sheet, so it can ensure that the metal sheets are pushed one by one, and can avoid squeezing and deforming the metal sheets when pushing them, which is beneficial to the subsequent stamping of the metal sheets. The U-shaped movable plate 101 moves downward and pushes the push-pull rod 103 to the right through the connecting plate 102, thereby causing the push plate 9 to move to the right and disengage from the die 6, avoiding affecting the subsequent stamping of the metal sheet by the punch 5. When the lifting plate 3 moves down to contact the inclined surface at the top of the contact plate 142, the lifting plate 3 continues to move down to squeeze the inclined surface at the top of the contact plate 142, so that the contact plate 142 moves to the left, and the tension spring 143 is stretched accordingly. When the lifting plate 3 passes over the contact plate 142, the contact plate 142 moves to the right and resets under the restoring action of the tension spring 143. Then the lifting plate 3 drives the punch 5 to continue to move down and cooperate with the die 6 to punch the metal sheet into automotive parts. After the automobile parts are stamped, the lifting plate 3 drives the punch 5 to move up and separate from the die 6, and the lifting plate 3 moves up to contact the contact plate 142 and push the contact plate 142 to move up. The contact plate 142 moves up to drive the L-shaped pull plate 141 to move up, thereby pulling the connecting block 121 with the U-shaped ejector rod Ⅰ123 and the U-shaped ejector rod Ⅱ124 to move up to eject the stamped parts in the die 6. When the U-shaped ejector rod Ⅱ124 moves up to contact the limit block 126, the U-shaped ejector rod Ⅱ124 is limited by the limit block 126 and cannot continue to move up, so that the front U-shaped connecting rod 122 continues to move up to compress the spring 1 25 is compressed, while the U-shaped ejector rod Ⅰ123 continues to move upward so that the part is in an inclined state with a low front and a high back after being ejected, so that the part slides forward along the U-shaped ejector rod Ⅰ123 and the U-shaped ejector rod Ⅱ124 to realize automatic unloading; when the contact plate 142 moves upward and contacts the push plate 15, the push plate 15 squeezes the inclined surface on the top of the contact plate 142 so that the contact plate 142 moves to the left and separates from the lifting plate 3, and the tension spring 143 is stretched accordingly, so that the entire ejection frame 12 and the pulling frame 14 move downward and reset under the action of their own gravity to avoid affecting the next round of stamping work.When the metal sheet moves to the left onto the die 6, the metal sheet squeezes the inclined surface on the right positioning block 162, so that the right positioning block 162 moves downward, and the right supporting spring 163 is compressed accordingly, ensuring that the metal sheet moves smoothly to the left onto the die 6. When the metal sheet passes over the right positioning block 162 to the left, the right supporting spring 163 resets the right positioning block 162 to move up and block the metal sheet. In this way, the metal sheet can be positioned by the positioning block 162 to prevent the push plate 9 from moving to the right and taking the metal sheet away from the die 6. The inclined surface on the front positioning block 162 can guide the stamped parts, so that when the parts are ejected from the die 6 and are in an inclined state with low front and high back, they can slide forward along the inclined surface on the front positioning block 162. In this way, the loading and unloading structure of the equipment is closely integrated with the stamping die, which greatly reduces the occupied space of the production workshop and increases the available space in the production workshop. With the increase of available space, the production workshop can more flexibly adjust the production line and layout, optimize the space utilization of the production workshop, and improve the space utilization rate of the workshop. In addition, when the punch 5 moves down, the equipment pushes the metal sheet to the die 6 to complete the loading, and when the punch 5 moves up, the parts stamped in the die 6 are ejected, and the parts are ejected to a state of being low in front and high in the back and sliding forward to complete the unloading. There is no need to pause to reserve time for loading and unloading, and the parts can be stamped continuously to improve the stamping efficiency. This solves the problem that the structure for loading and unloading the metal sheet in the prior art is not integrated with the stamping die, occupies a large space on both sides of the stamping die, and directly leads to a reduction in the available space in the production workshop. After each stamping is completed, the stamping equipment needs to pause to reserve time for loading and unloading, resulting in extended stamping time and reduced stamping efficiency.

[0028] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.
