Description

Technical Field

[0001] This technical solution relates to the field of stamping die technology, specifically to a side-bending punching die. Background Technology

[0002] Currently, a typical oven consists of an inner cavity, an outer shell, and a control panel. To facilitate the connection and assembly of the control panel and the inner cavity, the bottom edge of the inner cavity needs to be bent, specifically processed into a U-shaped edge. Furthermore, some inner cavity bottom edge flanges require punching to accommodate sealing rings. The existing processing methods for inner cavity bottom edge flanges have the following problems:

[0003] 1. Bending and punching processes need to be carried out on two separate machines. Multiple machines not only occupy a large space and have high costs, but also require manual transfer of the inner liner bottom plate between machines, resulting in low production efficiency. At the same time, after the transfer, the inner liner bottom plate needs to be repositioned, which can easily lead to production errors and reduce the product yield.

[0004] 2. Traditional inner liner bottom plate bending is usually performed vertically. The material is placed vertically into the mold of the processing equipment, and the upper end is bent into an inverted U-shape using two molds. When unloading, the inner liner bottom plate must be lifted and then removed horizontally. Due to the limited stroke height of the stamping equipment, product handling is inconvenient, affecting production efficiency. Furthermore, because the inner liner bottom plate must be loaded or unloaded vertically, it cannot be fitted with robotic arms for loading or unloading, relying on manual operation, resulting in poor usability, low production efficiency, and inability to achieve production automation. Utility Model Content

[0005] The purpose of this technical solution is to provide a side bending and punching mold, which uses an upper pressing device and a feeding table to fix the material, a bending device to bend the material edge, and a punching device to punch the material edge. This improves the problem of large space occupation and low production efficiency caused by the need for multiple machines to operate separately for bending and punching the inner liner bottom plate.

[0006] The purpose of this technical solution is achieved as follows:

[0009] Preferably, the bending device is provided with a side pressing mechanism, the bending die is provided with an avoidance notch, and the side pressing mechanism is movably placed within the avoidance notch; the side pressing mechanism includes: a side pressing plate, which is slidably connected to the front end of the bending slide and movably placed within the avoidance notch; and a side pressing elastic element, which is installed between the side pressing plate and the bending slide; when the bending slide moves toward the direction close to the feeding table, the side pressing elastic element undergoes elastic deformation, causing the side pressing plate to press the material against the bending part two.

[0010] Preferably, the bending device includes: at least one reset mechanism mounted on the base plate and connected to the bending slide, the reset mechanism being used to drive the bending slide to move away from the unloading platform; the reset mechanism includes: a reset fixing plate mounted on the upper end of the base plate and located behind the bending slide; a reset connecting rod slidably disposed on the reset fixing plate, the front end of the reset connecting rod being connected to the bending slide, and the rear end of the reset connecting rod being provided with a reset anti-detachment part; and a reset elastic member sleeved on the reset connecting rod, the front end of the reset elastic member abutting against the rear end of the reset fixing plate, and the rear end of the reset elastic member abutting against the reset anti-detachment part.

[0011] Preferably, the bending slide includes: a sliding seat slidably disposed on the base plate, and the upper end of the sliding seat is provided with a fixing groove one and a fixing groove two; a mounting seat mounted on the upper end of the sliding seat, and the lower end of the mounting seat is provided with a fixing protrusion one, the fixing protrusion one being inserted into the fixing groove one; and a bending die mounted on the upper end of the sliding seat, and the lower end of the bending die is provided with a fixing protrusion two, the fixing protrusion two being inserted into the fixing groove two.

[0012] Preferably, the punching device includes: at least one punching pin, which is mounted on the bending slide of the bending device, and the punching pin is located at the clearance notch of the bending die; the end of the second bending part of the feeding table is provided with a punch clearance groove corresponding to the punching pin; when the bending device moves toward the feeding table, the punching pin is inserted into the punch clearance groove and punches the material located on the punch clearance groove.

[0014] A demolding template is installed on the drive end of the demolding drive component; a clearance opening is provided on the feeding platform, allowing the rear end of the material to extend out of the upper end of the feeding platform; after the demolding drive component drives the demolding template to move toward the feeding platform, the demolding template abuts against the rear end of the material, causing the front end of the material to move toward the bending part two away from the feeding platform, thereby realizing that the folded edge of the front end of the material is separated from the bending part two.

[0015] Preferably, a demolding limiting member is provided at the upper end of the base plate. The demolding limiting member is located beside the feeding platform, and the distance between the end of the demolding limiting member and the demolding template is less than the distance between the clearance opening and the demolding template. The demolding limiting member abuts against the demolding template to limit the range of movement of the demolding template.

[0016] Preferably, the upper pressing device includes: an upper mounting plate; an upper pressing plate slidably disposed at the lower end of the upper mounting plate; and an upper pressing elastic element connected between the upper pressing plate and the upper mounting plate. When the upper pressing device moves toward the upper end of the feeding platform, the upper pressing elastic element undergoes elastic deformation, causing the upper pressing plate to press the material against the upper end of the feeding platform.

[0017] Preferably, the upper mounting plate is provided with an upper inclined wedge mounting groove, and the upper end of the upper inclined wedge of the upper pressing device is installed in the upper inclined wedge mounting groove.

[0018] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0019] 1. This technical solution uses an upper pressing device and a feeding platform to fix the material, a bending device to bend the material edges, and a punching device to punch the material edges. This integrated approach to fixing, bending, and punching the material improves production efficiency. The integrated design reduces the number of devices, lowers space requirements and equipment costs. It also avoids manual material handling between multiple devices, shortens operation time, and increases production efficiency. Furthermore, since repositioning is not required, it reduces positioning errors and improves product yield.

[0020] 2. This technical solution places the material horizontally on the feeding platform, and uses the upper pressing device and the feeding platform to press and fix the material from the top and bottom. After the material is placed horizontally, it is easy to remove it from the feeding platform. It can be used with a robot to load or unload the material, so it can be connected and coordinated with the equipment of the previous production station. There is no need for manual loading or unloading, which improves production efficiency and production automation.

[0021] 3. This technical solution changes the vertical force of the upper pressing device to a horizontal force through the cooperation between the upper and lower inclined wedges. This allows the upper pressing device to approach the unloading table, driving the bending slide and bending die to approach the unloading table, thus realizing the bending operation of the material. Only one drive source is needed to drive the upper pressing device to move downward, which can complete the fixing and bending operation of the material, thereby improving production efficiency.

[0022] 4. This technical solution sets punching pins on the bending slide of the bending device. When the bending slide moves to make the bending die cooperate with the feeding table to realize the bending operation of the material edge, the punching pins cooperate with the punching avoidance holes of the bending part two of the feeding table to punch the material edge. No additional production steps and equipment are required, thus improving production efficiency. Attached Figure Description

[0046] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-15 .

[0047] Combination Figure 1 , Figure 7 and Figure 14 A side-bending punching die includes: a base plate 1, a feeding platform 2, an upper pressing device 3, a bending device 4, a punching device 5, and a demolding device 6; the feeding platform 2 is installed on the upper end of the base plate 1, and a feeding groove 21 is formed on the upper end of the feeding platform 2. The shape of the feeding groove 21 is adapted to the shape of the material 100, and the feeding groove 21 of the feeding platform 2 is used to place the material 100 to be bent; the upper pressing device 3 is installed above the base plate 1, and the upper pressing device 3 is used to press the material 100 on the upper end of the feeding platform 2, that is, the upper pressing device 3 presses the material 100 on the feeding platform 2 in the vertical direction. The upper pressing device 3 is used to be installed on the frame of the bending equipment and connected to the drive source on the frame to realize the movement operation of the upper pressing device 3 towards or away from the feeding platform 2; the bending device 4 is installed on the base plate 1 and located on one side of the feeding platform 2. The bending device 4 can move towards or away from the side end of the feeding platform 2, that is, as shown in the figure. Figure 1As shown, the bending device 4 can move left and right on the base plate 1. The bending device 4 is used to bend the folded edge 101 of the material 100 on the feeding table 2. The punching device 5 is installed on the bending device 4 and moves with the bending device 4. The punching device 5 is used to punch the folded edge 101 of the material 100. When the bending device 4 approaches the feeding table 2 and bends the folded edge 101 of the material 100, the punching device 5 moves towards the feeding table 2 simultaneously and punches the folded edge 101 of the material 100, improving production efficiency and eliminating the need for additional punching equipment, thus saving production costs. The demolding device 6 is installed on the base plate 1 and located on the other side of the feeding table 2. The bending device 4 and the demolding device 6 are arranged opposite each other on both sides of the feeding table 2. The demolding device 6 is used to remove the bent and punched material 100 from the feeding table 2, thereby facilitating the mechanical gripper to unload the material 100 and realize production automation.

[0048] Combination Figure 2 , Figure 4 , Figure 7 and Figure 8The bending device 4 includes: a bending slide 41, a bending die 42, and at least one reset mechanism 43; the bending slide 41 is slidably mounted on the base plate 1, and the bending slide 41 is provided with at least one lower inclined wedge 44, and a guide surface 441 is provided on the rear side of the upper end of the lower inclined wedge 44, the guide surface 441 being inclined away from the bending die 42; the bending die 42 is mounted on the bending slide 41, and the bending die 42 is provided with a bending part 421; a bending part 22 is provided on the side end of the feeding table 2, and at least one upper inclined wedge 31 corresponding to the lower inclined wedge 44 is provided at the lower end of the upper pressure device 3, the upper inclined wedge 31 is provided on the side near the upper pressure plate 33, the guide surface 311 is inclined towards the upper pressure plate 33, and the horizontal projection of the lowermost end of the guide surface 311 on the plane where the bending device 4 moves is located at the uppermost end of the guide surface 441 on the bending device 4. The horizontal projection of the moving direction on the plane allows the guide surface 311 to slide on the guide surface 441. When the upper pressing device 3 moves toward the direction of the feeding platform 2, the upper wedge 31 slides against the lower wedge 44, and the guide surface 441 slides on the guide surface 311, causing the bending slide 41 to move toward the feeding platform 2 on the base plate 1. This allows the bending part 22 to cooperate with the bending part 421 to bend the folded edge 101 of the material 100. That is, the bending part 421 abuts against the outer edge of the folded edge 101 of the material 100 and bends the outer edge of the folded edge 101 toward the direction of the bending part 22, so that the material 100 changes from an L-shaped cross section to a U-shaped cross section. The reset mechanism 43 is installed on the base plate 1 and connected to the bending slide 41. The reset mechanism 43 is used to drive the bending slide 41 to move away from the feeding platform 2, thereby resetting the bending slide 41.

[0049] Combination Figure 2 , Figure 10 The bending slide 41 includes a sliding seat 45 and a mounting seat 46. The sliding seat 45 is slidably mounted on the base plate 1, and the upper end of the sliding seat 45 is provided with a first fixing groove 451 and a second fixing groove 452, which are distributed on the sliding seat 45 along a direction perpendicular to the sliding direction of the sliding seat 45. The mounting seat 46 is bolted to the upper end of the sliding seat 45 and is located at the rear end of the bending die 42, and the lower end of the mounting seat 46 is provided with a fixing protrusion. A first fixing protrusion 461 is inserted into a first fixing groove 451; a bending die 42 is installed on the upper end of a sliding seat 45, and a second fixing protrusion 422 is provided at the lower end of the bending die 42. The second fixing protrusion 422 is inserted into the second fixing groove 452 to improve the connection strength between the bending die 42 and the sliding seat 45, and to prevent the reaction force exerted by the folded edge 101 of the material 100 on the bending die 42 from causing the connection between the bending die 42 and the sliding seat 45 to loosen.

[0050] Combination Figure 9 and Figure 10 The sliding seat 45 has sliding parts 453 at both ends. A sliding limit block 11 is provided on the base plate 1. The sliding limit block 11 and the upper end of the base plate 1 form a sliding groove 111. The two ends of the sliding seat 45 are placed in the sliding groove 111 to realize the sliding of the sliding seat 45 on the base plate 1. A mounting seat guide rod 462 is connected to the mounting seat 46. A mounting seat guide block 12 is provided on the base plate 1. A mounting seat guide sleeve 121 is provided on the mounting seat guide block 12. The mounting seat guide rod 462 is slidably inserted into the mounting seat guide sleeve 121.

[0051] Combination Figures 9-12 The upper rear side of the mounting base 46 is provided with a lower inclined wedge mounting groove 463, and the lower inclined wedge 44 is installed in the lower inclined wedge mounting groove 463 by bolts. The guide surface 441 is inclined towards the upper rear side of the mounting base 46.

[0052] Combination Figure 2 , Figure 9 and Figure 10 The bending device 4 is equipped with a side pressing mechanism 7, and the upper middle part of the bending die 42 is provided with a clearance notch 423. When the bending die 42 and the feeding table 2 are bending, the side pressing mechanism 7 is movably placed in the clearance notch 423. The side pressing mechanism 7 presses the folded edge 101 of the material 100 against the end of the bending part 22. The bending part 22 of the feeding table 2 can be placed in the clearance notch 423, and the outer wall of the bending part 22 and the inner wall of the clearance notch 423 respectively press against the two sides of the folded edge 101 of the material 100, thereby realizing the bending of the folded edge 101 of the material 100.

[0053] Combination Figures 9-12 The side-pressing mechanism 7 includes a side-pressing plate 71 and a side-pressing elastic element 72. The side-pressing plate 71 is slidably connected to the front end of the bending slide 41 and is movably positioned within the clearance notch 423. The side-pressing plate 71 is provided with a side-pressing plate guide rod 711, and a side-pressing plate guide sleeve 464 is provided on the mounting base 46 of the bending slide 41. The side-pressing plate guide rod 711 is slidably inserted into the side-pressing plate guide sleeve 464. The side-pressing elastic element 72 is a nitrogen spring, and the side-pressing elastic element 72 is installed between the side-pressing plate 71 and the bending slide 41. Between the bending slide 41; when the bending slide 41 moves toward the direction of the feeding table 2, the side pressing elastic member 72 undergoes elastic deformation, so that the side pressing plate 71 presses the material 100 against the bending part 22. The side pressing elastic member 72 ensures the force of the side pressing plate 71 pressing against the folded edge 101 of the material 100. At the same time, when the bending slide 41 moves away from the feeding table 2 to reset, the side pressing elastic member 72 realizes that the side pressing plate 71 moves on the bending slide 41 to the set position, that is, the side pressing plate 71 is reset.

[0054] Combination Figure 1 , Figure 2 , Figure 11 and Figure 12 This technical solution provides several reset mechanisms 43, which are distributed along the length of the bending slide 41. That is, several reset mechanisms 43 are arranged on the base plate 1 and connected to the rear end of the bending slide 41 in a direction perpendicular to the movement of the bending slide 41. Each reset mechanism 43 includes: a reset fixing plate 431, a reset connecting rod 432, and a reset elastic element 433. The reset fixing plate 431 is installed on the upper end of the base plate 1 by bolts and is located behind the bending slide 41. The reset connecting rod 432 is slidably disposed on the reset fixing plate 431, and the front end of the reset connecting rod 432 is connected to the bending slide 41. The rear end of the reset connecting rod 432 is provided with a reset anti-detachment part 4321. The reset elastic element 433 is a spring. The reset elastic element 433 is sleeved on the reset connecting rod 432, and the front end of the reset elastic element 433 abuts against the rear end of the reset fixing plate 431. The rear end of the reset elastic element 433 abuts against the reset anti-detachment part 4321. The mounting base 46 of the bending slide 41 is provided with a reset guide rod 465. The reset fixing plate 431 is provided with a reset guide sleeve 4311. The end of the reset guide rod 465 is slidably placed in the reset guide sleeve 4311. The reset elastic element 433 undergoes elastic deformation, causing the reset connecting rod 432 to move away from the reset fixing plate 431, thereby causing the reset connecting rod 432 to drive the bending slide 41 to move away from the feeding table 2.

[0055] Combination Figures 9-11 The punching device 5 includes at least one punching pin 51, which is mounted on the bending slide 41 of the bending device 4 and is located in the clearance notch 423 of the bending die 42. The end of the bending section 22 of the feeding table 2 is provided with a punch clearance groove 221 corresponding to the punching pin 51. When the bending device 4 moves toward the feeding table 2, the front end of the punching pin 51 passes through the folded edge 101 of the material 100 and is inserted into the punch clearance groove 221, thereby realizing the punching operation on the material 100 located in the punch clearance groove 221 of the bending section 22.

[0056] The side pressure plate 71 is provided with a punch clearance hole 712, which passes through the front and rear ends of the side pressure plate 71. The front end of the punching punch 51 passes through the side pressure plate 71 through the punch clearance hole 712, thereby realizing the punching operation on the folded edge 101 of the material 100 on the bending part 22.

[0057] Combination Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8The demolding device 6 includes at least one demolding drive 61 and a demolding template 62. In this technical solution, the driving ends of several demolding drive 61s are connected to the same demolding template 62. The demolding drive 61 is a cylinder, and it is mounted on the base plate 1. The demolding template 62 is mounted on the driving end of the demolding drive 61. A clearance opening 211 is provided on the feeding platform 2, allowing the rear end of the material 100 to extend beyond the upper end of the feeding platform 2, thus allowing the rear end of the material 100 to extend beyond the feeding groove 21. After the bending device 4 completes the bending operation, the reset mechanism 43 causes the bending slide 41 to face away from the feeding platform. After the platform 2 moves in the direction, the demolding drive 61 drives the demolding template 62 to move towards the direction of the feeding platform 2. The demolding template 62 abuts against the rear end of the material 100, driving the folded edge 101 at the front end of the material 100 to move away from the bending part 22 of the feeding platform 2. This causes the front end of the material 100 to extend out of the feeding groove 21, realizing that the U-shaped folded edge 101 at the front end of the material 100 is separated from the bending part 22. This allows the bent material 100 to move up and down in the feeding groove 21, which facilitates the unloading of the bent material 100. It can be adapted to the robot for unloading, improving production automation.

[0058] Combination Figure 7 and Figure 8 A demolding limiter 13 is provided at the upper end of the base plate 1. The demolding limiter 13 is located beside the clearance opening 211 of the feeding platform 2, and the distance between the end of the demolding limiter 13 and the demolding template 62 is less than the distance between the clearance opening 211 and the demolding template 62. The demolding limiter 13 abuts against the demolding template 62 to limit the range of movement of the demolding template 62, and to prevent the demolding template 62 from driving the material 100 to move a distance on the feeding platform 2 greater than the set value, which would cause the folded edge 101 of the material 100 to abut against the bending device 4, thereby preventing the folded edge 101 of the material 100 from deforming and being damaged.

[0059] Combination Figures 14-15 The upper pressing device 3 includes an upper mounting plate 32, an upper pressing plate 33, and an upper pressing elastic element 34. The upper pressing plate 33 is slidably disposed at the lower end of the upper mounting plate 32. The upper pressing plate 33 is provided with an upper pressing plate guide sleeve 331, and the upper mounting plate 32 is provided with an upper pressing plate guide rod 321. The end of the upper pressing plate guide rod 321 is slidably disposed within the upper pressing plate guide sleeve 331. The upper pressing elastic element 34 is a nitrogen spring. The upper pressing elastic element 34 connects the upper pressing plate 33 and the upper mounting plate 32, allowing the upper pressing plate 33 to move toward or away from the upper mounting plate 32. When the upper pressing device 3 moves toward the upper end of the discharge platform 2, the upper pressing elastic element 34 undergoes elastic deformation, causing the upper pressing plate to press the material 100 against the upper end of the discharge platform 2. The elastic deformation of the upper pressing elastic element 34 ensures the force of the upper pressing plate 33 pressing against the material 100.

[0060] like Figure 15The upper mounting plate 32 has an upper inclined wedge mounting groove 322. The upper end of the upper inclined wedge 31 is inserted into and installed in the upper inclined wedge mounting groove 322. The side wall of the upper inclined wedge mounting groove 322 abuts against the side wall of the upper inclined wedge 31 to ensure that the upper inclined wedge 31 is installed securely.

[0061] The lower end of the upper mounting plate 32 is provided with a positioning post 323 and a limiting post 324. The upper end of the feeding platform 2 is provided with a positioning hole 23. The upper end of the base plate 1 is provided with a limiting post 15. The positioning post 323 corresponds to the positioning hole 23, and the limiting post 324 corresponds to the limiting post 15. When the upper pressing device 3 moves toward the feeding platform 2 and the base plate 1 to press the material, the positioning post 323 is inserted into the positioning hole 23, and the lower end of the limiting post 324 abuts against the upper end of the limiting post 15.

[0062] A stamping guide mechanism 16 is provided between the upper mounting plate 32 and the base plate 1. The specific stamping guide mechanism 16 can be found in the stamping guide device disclosed in Chinese Patent CN201921987801.6, which will not be described in detail here.
