Description

Technical Field

[0001] The present invention relates to the field of stamping machines, and specifically to a die with precise alignment of upper and lower dies. Background Technique

[0002] A stamping machine is one of the metal material processing machines. It uses stamping technology to form, shear or punch metal sheets and other materials. The classification of stamping machines can be divided according to two aspects: operation mode and processing method. Stamping machines can be divided into manual stamping machines, mechanical stamping machines, hydraulic stamping machines, pneumatic stamping machines, and numerical control stamping machines, etc. And according to the processing method, stamping machines can be divided into multiple types such as fitting, shearing, stretching, punching, and bending. Generally, when using a stamping machine for operations such as shearing and punching, in order to punch accurately, a die with precise alignment of upper and lower dies needs to be used to improve its production quality.

[0003] For existing stamping machines, when using a die with precise alignment of upper and lower dies, if the processed material is a soft material, during punching and shearing, it may cause residual material to adhere to the lower die. If not noticed and processed again, it may cause the material residue to affect the processing of the next soft material. Therefore, when designing a die with precise alignment of upper and lower dies, it is necessary to consider a cleaning mechanism that can automatically clean the lower pressing die after each punching and shearing to avoid the above situation. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a die with precise alignment of upper and lower dies to solve the technical problem that traditional dies with precise alignment of upper and lower dies have residual adhered materials when processing soft materials.

[0005] To achieve the above object, the present invention provides the following technical solution: A die with precise alignment of upper and lower dies, including a machine body and a mounting seat. Cleaning mechanisms are provided on both sides of the mounting seat. The cleaning mechanism includes two mounting plates. A connecting rod is rotatably connected inside the two mounting plates. First gears are provided at both ends of the connecting rod. A cleaning roller is rotatably connected to the outer surface of the connecting rod. A hydraulic press is provided at the top of the machine body.

[0006] By adopting the above technical solution, since cleaning mechanisms are provided on both sides of the mounting seat, and the cleaning mechanism includes two mounting plates, and a connecting rod is rotatably connected inside the two mounting plates, the connecting rod can be effectively installed through the mounting plates and it can be ensured that the connecting rod can rotate.

[0007] Further, a hydraulic pressure rod is provided at the output end of the hydraulic press. The bottom of the hydraulic pressure rod is detachably connected to an upper pressing die. Mounting rods penetrate through both sides of the upper pressing die. Second gears are rotatably connected to both ends of the mounting rods. The second gears are meshed with the first gears.

[0008] By adopting the above technical solution, since the mounting rods penetrate through both sides of the upper pressing die, and both ends of the mounting rods are rotatably connected with second gears, and the second gears are meshed with the first gears, during the telescopic process of the hydraulic rod, the second gears will rotate, and then the second gears will drive the first gears to rotate.

[0009] Furthermore, the lower pressing die is detachably connected to the middle of the top of the mounting base, and a plurality of round holes are formed inside the lower pressing die. There are a plurality of the round holes, and the plurality of round holes are arranged equidistantly and uniformly.

[0010] By adopting the above technical solution, since the lower pressing die is detachably connected to the middle of the top of the mounting base, the raw material plate can be effectively placed through the lower pressing die, which is also beneficial to the subsequent punching operation.

[0011] Furthermore, a plurality of positioning pins are arranged on the top of the lower pressing die, and the plurality of positioning pins are arranged in a rectangular array.

[0012] By adopting the above technical solution, since a plurality of positioning pins are arranged on the top of the lower pressing die, when positioning holes are formed in the soft plate to be processed in advance, and then the positioning holes are inserted onto the positioning pins, the raw materials can be effectively and accurately positioned, so as to achieve the purpose of accurate alignment of the upper and lower dies and the materials.

[0013] Furthermore, a storage box is arranged at the bottom of the lower pressing die, and a handle is arranged on the outer surface of the storage box.

[0014] By adopting the above technical solution, since a storage box is arranged at the bottom of the lower pressing die, the processed materials can be effectively stored through the storage box, and it is convenient for workers to transport them to the next processing site, so as to play a role in transportation.

[0015] Furthermore, the upper pressing die and the lower pressing die are of the same size and are adapted to each other.

[0016] By adopting the above technical solution, since the upper pressing die and the lower pressing die are of the same size, it is more convenient to process the upper pressing die and the lower pressing die.

[0017] Furthermore, a control console is welded to the front end of the top of the mounting base, and an emergency stop button and two control buttons are arranged on the control console.

[0018] By adopting the above technical solution, since a control console is welded to the front end of the top of the mounting base, the operation position of the operation console is more convenient for workers to operate, and it will not cause any trouble to the workers during operation.

[0019] Furthermore, a distribution box is arranged on one side of the machine body, a distributor is arranged inside the distribution box, and the distributor is electrically connected to an external power supply.

[0020] By adopting the above technical solution, since a distribution box is provided on one side of the machine body, the oil press can operate normally through the distribution box.

[0021] Furthermore, both the machine body and the cleaning mechanism are made of stainless steel, and the cleaning roller is made of sponge.

[0022] By adopting the above technical solution, since both the machine body and the cleaning mechanism are made of stainless steel, the machine body and the cleaning mechanism have high hardness and antioxidant effects, thereby ensuring a relatively long service life of both the machine body and the cleaning mechanism.

[0023] Furthermore, a display screen is provided on the outer surface of the upper pressing die, and the display screen, the oil press, and the control console are electrically connected.

[0024] By adopting the above technical solution, since a display screen is provided on the outer surface of the upper pressing die, the pressure value of the oil press can be displayed through the display screen.

[0025] In summary, the present invention mainly has the following beneficial effects:

[0026] 1. By setting up a cleaning mechanism in the present invention, when the oil press moves, the oil pressure rod will move vertically, so that the upper pressing die and the lower pressing die are fitted together to achieve the purpose of punching and cutting holes. After the upper pressing die is lifted, since two second gears are installed on both sides of the upper pressing die through mounting rods, and the second gears are engaged with the first gear, at this time the second gears will drive the first gears to rotate. Subsequently, the first gears will flatten the connecting rods, allowing the cleaning rollers to perform cleaning operations on the lower pressing die to sweep away the attached materials. And after the upper pressing die presses down again, the second gears will be flipped, and then the first gears will lift the connecting rods to avoid the connecting rods interfering with the processing of materials by the machine body. Through the above settings, it can effectively and quickly and automatically clean the attachments on the lower pressing die, and at the same time can effectively avoid cleaning interfering with processing;

[0027] 2. By setting positioning pins in the present invention, since multiple positioning pins are provided on the lower pressing die, and positioning holes are provided on the soft plate to be processed in advance, when the positioning holes are inserted into the positioning pins, the raw materials can be accurately positioned effectively, so as to achieve the purpose of accurate alignment of the upper and lower dies and the materials, and can also effectively avoid the situation that the raw materials shift laterally during processing, resulting in product damage.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0034] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0035] A mold for accurate alignment of upper and lower dies, as Figures 1-4 shown, includes a body 1, a mounting seat 9. Cleaning mechanisms 7 are provided on both sides of the mounting seat 9. The cleaning mechanism 7 includes two mounting plates 701. A connecting rod 702 is rotatably connected to the inner sides of the two mounting plates 701. First gears 703 are provided at both ends of the connecting rod 702. A cleaning roller 706 is rotatably connected to the outer surface of the connecting rod 702. A hydraulic press 2 is provided at the top of the body 1. Since cleaning mechanisms 7 are provided on both sides of the mounting seat 9 and the cleaning mechanism 7 includes two mounting plates 701 and a connecting rod 702 is rotatably connected to the inner sides of the two mounting plates 701, the connecting rod 702 can be effectively mounted through the mounting plate 701 and it can be ensured that the connecting rod can rotate. Since first gears 703 are provided at both ends of the connecting rod 702 and a cleaning roller 706 is rotatably connected to the outer surface of the connecting rod 702, the top of the lower die 4 can be cleaned by the cleaning roller 706.

[0036] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, an oil pressure rod 13 is provided at the output end of the hydraulic press 2. The bottom of the oil pressure rod 13 is detachably connected to the upper pressing die 3. Installation rods 705 penetrate through both sides of the upper pressing die 3. Second gears 704 are rotatably connected to both ends of the installation rods 705. The second gears 704 are meshed with the first gears 703. Since the oil pressure rod 13 is provided at the output end of the hydraulic press 2, the oil pressure rod 13 can be telescoped when the hydraulic press 2 is started. Since the installation rods 705 penetrate through both sides of the upper pressing die 3 and the second gears 704 are rotatably connected to both ends of the installation rods 705 and the second gears 704 are meshed with the first gears 703, during the telescoping process of the oil pressure rod 13, the second gears 704 will rotate, and then the second gears 704 will drive the first gears 703 to rotate.

[0037] Refer to Figure 1 , Figure 2 , Figure 3 , a lower pressing die 4 is detachably connected to the middle of the top of the mounting seat 9. A plurality of round holes 14 are formed inside the lower pressing die 4. There are a plurality of round holes 14, and the plurality of round holes 14 are arranged equidistantly and uniformly. Since the lower pressing die 4 is detachably connected to the middle of the top of the mounting seat 9, the raw material plate can be effectively placed through the lower pressing die 4, which is also beneficial to subsequent punching operations. Since a plurality of round holes 14 are formed inside the lower pressing die 4 and there are a plurality of round holes 14 arranged equidistantly and uniformly, a plurality of processed round pieces can be punched through the round holes 14.

[0038] Refer to Figure 1 , Figure 2 , Figure 3 , a plurality of positioning pins 15 are provided on the top of the lower pressing die 4, and the plurality of positioning pins 15 are arranged in a rectangular array. Since the plurality of positioning pins 15 are provided on the top of the lower pressing die 4, when positioning holes are formed in the soft plate to be processed in advance, and then the positioning holes are inserted onto the positioning pins 14, the raw materials can be effectively and accurately positioned, so as to achieve the purpose of accurate alignment of the upper and lower dies and the materials. Since the plurality of positioning pins 15 are arranged in a rectangular array, the positioning of the positioning pins 15 is relatively accurate.

[0039] Refer to Figure 1 , Figure 2 , Figure 3 , a storage box 5 is provided at the bottom of the lower pressing die 4. A handle 6 is provided on the outer surface of the storage box 5. Since the storage box 5 is provided at the bottom of the lower pressing die 4, the processed materials can be effectively stored through the storage box 5, and it can ensure that the materials can be safely and effectively transported to the next processing site. Since the handle 6 is provided on the outer surface of the storage box 5, the storage box 5 can be pulled out or inserted through the handle 6.

[0040] Refer to Figure 1 , Figure 2 , Figure 3, the upper pressing die 3 is the same size as the lower pressing die 4, and the upper pressing die 3 is adapted to the lower pressing die 4. Since the upper pressing die 3 and the lower pressing die 4 are the same size, it is relatively convenient to process the upper pressing die 3 and the lower pressing die 4. Since the upper pressing die 3 is adapted to the lower pressing die 4, after the upper pressing die 3 is pressed down, it can well process the raw materials on the lower pressing die 4.

[0041] Refer to Figure 1 , Figure 2 , Figure 3 , a control console 8 is welded to the front end of the top of the mounting base 9. An emergency stop button 16 and two control buttons 10 are arranged on the control console 8. Since the control console 8 is welded to the front end of the top of the mounting base 9, the operating position of the operating console 8 is relatively convenient for workers to operate. Since the emergency stop button 16 and the two control buttons 10 are arranged on the control console 8, the hydraulic press 2 can be instantly stopped by the emergency stop button 16, and to start the hydraulic press 2, the two control buttons 10 need to be pressed simultaneously to prevent the worker's hand from not leaving the lower pressing die 4 and being squeezed.

[0042] Refer to Figure 1 , Figure 2 , Figure 3 , a distribution box 12 is arranged on one side of the machine body 1. A distributor is arranged inside the distribution box 12, and the distributor is electrically connected to an external power supply. Since the distribution box 12 is arranged on one side of the machine body 1, the normal operation of the hydraulic press 2 can be ensured through the distribution box 12. Since the distributor is arranged inside the distribution box 12 and the distributor is electrically connected to the external power supply, the hydraulic press 2 can be safely powered through the distributor.

[0043] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , both the machine body 1 and the cleaning mechanism 7 are made of stainless steel. The cleaning roller 706 is made of sponge. Since both the machine body 1 and the cleaning mechanism 7 are made of stainless steel, the service life of the machine body 1 and the cleaning mechanism 7 is relatively long. Since the cleaning roller 706 is made of sponge, the attached substances can be wiped off through the sponge.

[0044] Refer to Figure 1 , Figure 2 , Figure 3 , a display screen 11 is arranged on the outer surface of the upper pressing die 3. The display screen 11, the hydraulic press 2, and the control console 8 are electrically connected. Since the display screen 11 is arranged on the outer surface of the upper pressing die 3, the pressure value of the hydraulic press 2 can be displayed through the display screen 11. Since the display screen 11, the hydraulic press 2, and the control console 8 are electrically connected, the display screen 11, the hydraulic press 2, etc. can be effectively controlled through the control console 8.

[0045] The implementation principle of this embodiment is as follows: First, the machine body 1 needs to be installed and connected to an external power supply through the distribution box 12. Subsequently, before use, different upper pressing dies 3 and lower pressing dies need to be installed according to the materials and requirements. Then, since there are multiple positioning pins 15 on the lower pressing die 4, and positioning holes are provided on the soft plate that needs to be processed in advance. At this time, inserting the positioning holes onto the positioning pins 14 can effectively position the raw materials accurately, so as to achieve the purpose of precise alignment of the upper and lower dies and the materials. After placing the materials on the lower pressing die 3, two control buttons 10 can be pressed simultaneously with both hands. At this time, the hydraulic press 2 can be started. Subsequently, the hydraulic rod 13 will press down to process the raw materials. During the processing, the hydraulic rod 13 will move vertically, so that the upper pressing die 3 is attached to the lower pressing die 4 to achieve the purpose of punching and cutting holes. After the upper pressing die 3 is lifted, since two second gears 704 are installed on both sides of the upper pressing die 3 through the mounting rods 705, and the second gears 704 are engaged with the first gear 703, at this time, the second gears 704 will drive the first gear 703 to rotate. Subsequently, the first gear 703 will flatten the connecting rod 702, so that the cleaning roller 706 can perform cleaning operations on the lower pressing die 4 to sweep away the attached materials. After the upper pressing die 3 presses down again, the second gears 704 will flip, and then the first gear 703 will lift the connecting rod 702 to prevent the connecting rod 702 from affecting the processing of the materials by the machine body 1.
