Abstract
Description
Technical Field
[0001] This application relates to the field of sheet metal stamping equipment technology, and more specifically, to a stamping equipment for manufacturing sheet metal parts that facilitates mold replacement. Background Technology
[0002] Sheet metal stamping equipment is a machine used to process metal sheets into various shapes through stamping, bending and other processes. It mainly consists of a machine body, crankshaft slider mechanism, punch die and pressing device. According to the driving method, it can be divided into mechanical, hydraulic and pneumatic types. This equipment is highly efficient and precise, and is suitable for mass production.
[0003] In related technologies, when a sheet metal is bent downwards under pressure at both ends simultaneously, the middle of the sheet metal is prone to bulging due to stress. To prevent this bulging, patent CN217798233U provides a sheet metal stamping device. This device uses the cooperation between a fixed die and a movable die. The sheet metal is placed on the upper surface of the fixed die. The user opens the stamping assembly, causing the stamping assembly to drive the mounting base downwards. This causes the lower surface of the movable die to press the sheet metal, bending it into a U-shape with the opening facing downwards. When the movable die contacts the upper surface of the sheet metal, the lower surface of the upper pressure plate also contacts the upper surface of the sheet metal. During the bending process of the sheet metal by the movable die, the upper pressure plate abuts against the middle of the sheet metal, preventing bulging in the middle of the sheet metal. The sheet metal bulges due to bending at both ends. When the lower surface of the movable mold contacts the lower surface of the forming cavity, the electric telescopic rod drives the movable mold to slide on the mounting base, causing the movable mold to move towards the fixed mold. This allows the movable mold to bend and attach the vertical sheet metal sheet to the surface of the fixed mold, completing the stamping of the sheet metal part. When the lower end of the movable mold first contacts the sheet metal surface, it bends the sheet metal. To prevent the upper end of the vertical plate from bulging due to the bending at the bottom, the upper pressure block moves down and squeezes the lower pressure block when the mounting base moves down. The lower pressure block is squeezed and moves away from the fixed mold, thereby causing the connecting block to pull out the piston. This creates a negative pressure on the suction cup surface and fixes it to the sheet metal surface, so that the upper end of the sheet metal is fixedly attached to the side wall of the fixed mold, reducing the possibility of bulging and improving the quality of the stamped sheet metal part.
[0004] Although the existing technical solutions mentioned above have solved the problem that the middle of the sheet metal is prone to bulging when both ends of the sheet metal are subjected to pressure and bent downwards, some sheet metal manufacturing molds are fixed by bolts, which requires manual operation by the staff when replacing them. In addition, some stamping molds are heavy, and it is very difficult for the staff to rotate the bolts while supporting the mold with their hands, making it inconvenient for the staff to replace them manually.
[0005] In view of this, we propose a stamping equipment for manufacturing sheet metal parts that facilitates mold replacement. Utility Model Content

[0031] The present application will be further described in detail below with reference to the accompanying drawings.
[0032] Reference Figure 1 , Figure 3 and Figure 4 This application discloses a stamping equipment for manufacturing sheet metal parts with easy mold replacement, including an operating table 1. An upper mold 2 is provided on one side of the operating table 1. An mounting plate A21 is fixedly provided on the top of the upper mold 2, and the upper mold 2 is installed and removed through the mounting plate A21. A lower mold 3 is provided at the bottom of the upper mold 2. An mounting plate B31 is fixedly provided at the bottom of the lower mold 3, and the lower mold 3 is installed and removed through the mounting plate B31. A replacement mechanism 4 is provided at the top of the upper mold 2 and the bottom of the lower mold 3 for installing and removing the upper mold 2 and the lower mold 3.
[0033] When the equipment is in use, the upper mold 2 and the lower mold 3 work together to stamp sheet metal parts. When it is necessary to replace the upper mold 2 and the lower mold 3, the replacement mechanism 4 first releases the fixing of the mounting plate A21 and the mounting plate B31, thereby releasing the fixing of the upper mold 2 and the lower mold 3. Then, the replacement mechanism 4 fixes the new upper mold 2 and the lower mold 3, completing the replacement process of the upper mold 2 and the lower mold 3, which makes it convenient for the staff to replace the upper mold 2 and the lower mold 3.
[0034] Reference Figure 1 - Figure 6Both replacement mechanisms 4 include four fixing plates 41. All eight fixing plates 41 move under external force, fixing mounting plates A21 and B31 onto two mounting blocks 42 respectively. The bottom mounting block 42 is fixedly mounted on one side of the operating table 1, and the top of the top mounting block 42 is equipped with a hydraulic push rod B5. The output end of the hydraulic push rod B5 is fixedly mounted to the top of the mounting block 42. Specifically, the eight fixing plates 41 move under the drive of eight hydraulic push rods A48. Two device slots B421 are opened on the side of each mounting block 42 that are close to each other. A drive motor 43 is fixedly mounted inside each of the four device slots B421. A threaded rod A44 is fixedly mounted at the output end of each of the four drive motors 43. A connecting rod 45 is fixedly mounted at one end of each of the four threaded rods A44, and a threaded rod B46 is fixedly mounted at one end of each of the four connecting rods 45. One end of the threaded rod B46 is rotatably mounted to the inner side of the corresponding device slot B421. Threaded moving blocks 47 are threaded onto the outer sides of the four threaded rods A44 and B46. The eight threaded moving blocks 47 drive the eight fixed plates 41 to move. Slide grooves 422 are provided on the inner sides of the four device slots B421. The four slide grooves 422 are slidably mounted with the eight threaded moving blocks 47. The operating table 1 includes two device slots A11. The two device slots A11 are located on one side of the operating table 1. The sides of the two device slots A11 that are close to each other are provided with a placement slot 12 that matches the mounting plate A21. A placement opening 13 is provided on the inner side of the placement slot 12. Four support columns 121 are fixedly mounted on the inner side of the placement slot 12. A slider 6 is fixedly mounted on the top of the hydraulic push rod B5. The slider 6 is slidably mounted on the inner side of the slide rail 61. The slide rail 61 is fixedly mounted to one side of the operating table 1.
[0035] When replacing the lower mold 3, four hydraulic push rods A48 drive four fixed plates 41 to move, releasing the fixing effect on the mounting plate B31. Two drive motors 43 drive the corresponding two threaded rods A44 to rotate, thereby driving the two connecting rods 45 and their connected threaded rods B46 to rotate. The two threaded rods A44 and B46 drive the threaded moving block 47 to move, thereby driving the hydraulic push rods A48 and fixed plates 41 to move, so that the lower mold 3 can be removed. Then, the new lower mold 3 is placed on the side of the corresponding mounting block 42. The above steps are reversed to complete the replacement process of the lower mold 3.
[0036] When replacing the upper mold 2, the slider 6 is driven by external force to slide inside the slide rail 61, so that the mounting plate A21 moves to the top of the placement slot 12. The upper mold 2 is then lowered into the placement opening 13 by the hydraulic push rod B5. The mounting plate A21 is supported by four support columns 121. Then, the four fixed plates 41 are moved by the four hydraulic push rods A48 to release the fixing effect on the mounting plate A21. The two drive motors 43 drive the corresponding two threaded rods A44 to rotate, thereby driving the two connecting rods 45 and their connected threaded rods B46 to rotate. The two threaded rods A44 and B46 drive the threaded moving block 47 to move, thereby driving the hydraulic push rods A48 and the fixed plate 41 to move, so that the upper mold 2 can fall into the placement opening 13. The mounting block 42 is moved by the hydraulic push rod B5 to move the replacement mechanism 4 away from the upper mold 2, so that the upper mold 2 can be taken out. Then, the new upper mold 2 is placed into the placement opening 13. The above steps are reversed to complete the replacement of the upper mold 2.
[0037] When the upper mold 2 falls into the placement port 13, the device slot A11 provides operating space for 4. When the upper mold 2 is taken out from the placement port 13, the operator can reach into the device slot A11 to take out the upper mold 2.
[0038] In summary, the sheet metal manufacturing stamping equipment disclosed in this application, which facilitates mold replacement, uses hydraulic push rod B5 to drive mounting block 42 to move downward, thereby driving upper mold 2 to move downward and cooperate with lower mold 3 to complete the stamping process of the equipment.
[0039] When replacing the lower mold 3, four hydraulic push rods A48 drive four fixed plates 41 to move, releasing the fixing effect on the mounting plate B31. Two drive motors 43 drive the corresponding two threaded rods A44 to rotate, thereby driving the two connecting rods 45 and their connected threaded rods B46 to rotate. The two threaded rods A44 and B46 drive the threaded moving block 47 to move, thereby driving the hydraulic push rods A48 and fixed plates 41 to move, so that the lower mold 3 can be removed. Then, the new lower mold 3 is placed on the side of the corresponding mounting block 42. The above steps are reversed to complete the replacement process of the lower mold 3.
[0040] When replacing the upper mold 2, the slider 6 is driven by external force to slide inside the slide rail 61, causing the mounting plate A21 to move to the top of the placement slot 12. The upper mold 2 is then lowered into the placement opening 13 by the hydraulic push rod B5. The mounting plate A21 is supported by four support columns 121. Then, the four fixed plates 41 are moved by the four hydraulic push rods A48 to release the fixing effect on the mounting plate A21. The two drive motors 43 drive the corresponding two threaded rods A44 to rotate, thereby driving the two connecting rods 45 and their connected threaded rods B46 to rotate. The two threaded rods A44 and B46 drive the threaded moving block 47 to move, thereby driving the hydraulic push rods A48 and the fixed plates 41 to move, so that the upper mold 2 can fall into the placement opening 13. The mounting block 42 is moved by the hydraulic push rod B5 to move the replacement mechanism 4 away from the upper mold 2, so that the upper mold 2 can be removed. Then, the new upper mold 2 is placed into the placement opening 13. The above steps are reversed to complete the replacement of the upper mold 2.
