Description

Technical Field

[0001] The present invention relates to the technical field of flat-top chain processing, and specifically to a processing device for flat-top chain plates. Background Art

[0002] The processing process of flat-top chains generally includes four processes: blanking, edge covering, bending, and curling. Blanking is to use a mold to form a metal sheet into the shape required for a flat-top chain. Edge covering is to shape and deburr the edges of the formed metal sheet. Bending is to first bend the metal sheet at a small angle, and curling is to continue bending the bent area of the metal sheet to the maximum extent so that a circular shape is formed at the bending position. Since the burrs on the edges of the metal sheet after blanking are not conducive to stacking and transportation, blanking and edge covering are generally processed continuously. After retrieval, a Chinese invention patent with the application number CN202211025462.X discloses a processing method for flat-top chain plates, which performs edge chamfering and pre-curling through an edge chamfering die and a pre-curling stamping die, and finally, when the pin hole forming die is closed, the inclined wedge acts on the slider.

[0003] The above device requires two molds for bending and curling the flat-top chain, which not only increases the cost of the molds, but also requires re-calibration and fixation when transferring the flat-top chain to a new mold, and it is easy to have a situation where the curling position does not correspond to the bending position. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a processing device for flat-top chain plates, which solves the technical problems that it is difficult for existing flat-top chain plate processing equipment to continuously complete the two processes of bending and curling with one mold, reduces the time consumed when replacing the mold, and at the same time reduces the possibility of non-corresponding bending and curling positions.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A processing device for flat-top chain plates includes a punching press main body, on which an operating table and a first hydraulic cylinder are installed. The bottom of the first hydraulic cylinder is installed with a gradient stamping assembly, and the top of the operating table is installed with a second hydraulic cylinder facing the gradient stamping assembly;

[0007] The gradient stamping assembly includes a mounting plate, a telescopic tube, a pressing and limiting assembly, and a bending part. The mounting plate is connected to the output end of the first hydraulic cylinder. The telescopic tube is installed at the bottom of the mounting plate. The pressing and limiting assembly is installed at the bottom of the telescopic tube. The bending parts are located on both sides of the mounting plate. A trapezoidal groove is opened at the top of the operating table, and the side surface of the bending part has the same radian as the side surface of the trapezoidal groove;

[0008] A first water storage tank is opened inside the bending part, a second water storage tank is opened inside the pressing and limiting assembly, and a wear-resistant hose is connected between the bending part and the pressing and limiting assembly.

[0009] Furthermore, the pressing and limiting component includes an intermediate plate and two cylinders. The intermediate plate is fixedly connected to the bottom of the telescopic tube. The two cylinders are respectively installed on both sides of the intermediate plate, and a square block is fixedly connected to the connection between the cylinder and the top of the intermediate plate.

[0010] Furthermore, a sealing frame penetrating to its interior is provided at the bottom of the pressing and limiting component. A heat conducting block is slidably connected inside the sealing frame. An annular groove is formed at the bottom of the heat conducting block, and a heat insulating frame is installed inside the annular groove.

[0011] Furthermore, the telescopic tube includes an outer tube, a slider and a spring. The outer tube is fixedly connected to the bottom of the mounting plate. The slider is fixedly connected to the top of the pressing and limiting component. One end of the slider extends into the outer tube movably, and the spring is installed inside the outer tube.

[0012] Furthermore, a belt conveyor extending into the trapezoidal groove movably is installed on one side of the operating table, and a buffer component is installed at the connection between the belt conveyor and the trapezoidal groove.

[0013] Furthermore, the buffer component includes a rotating rod and rubber sheets. Both ends of the rotating rod are rotatably connected to the inner wall of the trapezoidal groove, and the rubber sheets are installed on the outside of the rotating rod at equal intervals.

[0014] Furthermore, a feeding frame is installed on the top of the operating table. The top of the feeding frame is open, and a plurality of metal sheets are installed inside the feeding frame. A notch for putting the metal sheets is formed on one side of the feeding frame away from the operating table.

[0016] By means of the above technical solution, the present invention provides a processing device for flat-top chain plates, which has at least the following beneficial effects:

[0017] 1. By means of the gradient stamping component provided in the present invention, two working states of one die are used to continuously complete the two processes of bending and curling the flat-top chain plate, without the need to replace the die, reducing the time consumed for replacing the die and also reducing the possibility that the bending and curling positions do not correspond due to inaccurate positioning after replacing the die.

[0018] 2. By means of the first water storage tank, the second water storage tank and the wear-resistant hose provided in the present invention, the heat generated during the bending process can be absorbed when bending the metal sheet, and then the heat is transferred during the conversion process of different processes of metal sheet processing, and the heat is transferred to the area that has not been bent during the next bending of the metal sheet, so that the heat generated at the bent position of the metal sheet is evenly dispersed, reducing the possibility of damage caused by heat concentration in some areas during the processing of the flat-top chain plate.

[0019] 3. Through the heat-conducting block and heat-insulating frame provided in the present invention, heat generated during the bending process can be continuously dissipated into the surrounding air without bending the metal sheet, reducing the temperature of the water inside the first water storage tank, thereby maintaining the cooling effect on the bent position of the metal sheet. At the same time, when bending the metal sheet, the heat transferred to the unbent area in the middle of the metal sheet is controlled, reducing the possibility of excessive heat continuously transferred to the metal sheet.

[0020] 4. Through the buffer assembly provided in the present invention, not only the process of transferring the metal sheet from the belt conveyor to the trapezoidal groove is made smoother, but also the dust on the lower surface of the metal sheet can be cleaned during the feeding process of the metal sheet. At the same time, the dust in the trapezoidal groove near the rubber sheet area is cleaned by using air flow, reducing the influence of the dust settled inside the trapezoidal groove on the bending of the metal sheet.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] In order to continuously complete the two processes of bending and curling the flat-top chain link plate using a single mold, please refer to Figures 1 - 4 , this embodiment proposes a processing device for the flat-top chain link plate, which includes a punch press main body 1. An operating table 2 and a first hydraulic cylinder 3 are installed on one side of the punch press main body 1. Two second hydraulic cylinders 4 are installed on the top of the operating table 2. The output end of the first hydraulic cylinder 3 is installed with a gradient stamping assembly 5. The gradient stamping assembly 5 includes a mounting plate 51, a telescopic tube 52, a pressing and limiting assembly 53 and a bending part 54. The mounting plate 51 is connected to the output end of the first hydraulic cylinder 3. The telescopic tube 52 is installed at the bottom of the mounting plate 51. The pressing and limiting assembly 53 is installed at the bottom of the telescopic tube 52. The bending part 54 is located on both sides of the pressing and limiting assembly 53 and is fixed to the mounting plate 51 through a bracket. A trapezoidal groove 6 with an arc-shaped side surface is opened on the top of the operating table 2. The side of the bending part 54 away from the telescopic tube 52 has the same radian as the side surface of the trapezoidal groove 6. The height of the bending part 54 is within the telescopic range of the telescopic tube 52.

[0032] During use, one side of the operating table 2 is used for loading, which is the first station. The area between the gradient stamping assembly 5 and the operating table 2 when it moves downward is the second station. The area where the second hydraulic cylinder 4 extends horizontally to the trapezoidal groove 6 is the third station. The weight of the pressing and limiting assembly 53 pulls the telescopic tube 52 to extend downward to the maximum extent, so that the pressing and limiting assembly 53 drops to the lowest position. The metal sheet is moved from the first station along the trapezoidal groove 6 to directly below the gradient stamping assembly 5, and then the second station and the third station work in sequence to complete the processes of bending and curling the metal sheet in sequence, where:

[0033] The working process of the second station is as follows: The first hydraulic cylinder 3 pushes the gradient stamping assembly 5 downward until the pressing limit component 53 contacts the middle area of the metal sheet inside the trapezoidal groove 6, pressing the metal sheet and fixing it within the trapezoidal groove 6. The first hydraulic cylinder 3 continues to push the gradient stamping assembly 5 downward. At this time, the pressing limit component 53 has abutted against the inner wall of the trapezoidal groove 6, and the reaction force of the pressing limit component 53 pushes the telescopic tube 52 to shorten. The bending part 54 continues to descend until the bending part 54 presses the edge of the metal sheet against the arc surface on the side wall of the trapezoidal groove 6, squeezing the edge of the metal sheet into an arc with the same curvature as the side surface of the trapezoidal groove 6. The edge of the metal sheet extends along the side surface of the trapezoidal groove 6 to the outside of the trapezoidal groove 6, completing the process of bending the metal sheet.

[0034] The working process of the third station is as follows: The first hydraulic cylinder 3 drives the gradient stamping assembly 5 to rise a certain distance to ensure that the pressing limit component 53 continues to press the metal sheet tightly within the trapezoidal groove 6, while the bending part 54 rises above the pressing limit component 53. Then, the second hydraulic cylinder 4 extends, pushing the area of the metal sheet that extends outside the trapezoidal groove 6 after being bent towards the inside of the trapezoidal groove 6. During the bending process of the metal sheet, it is blocked by the pressing limit component 53 and finally adheres to the outside of the pressing limit component 53, causing the bent part of the metal sheet to bend into a shape that fits both sides of the pressing limit component 53, completing the process of curling the bent area of the metal sheet.

[0035] Finally, the second hydraulic cylinder 4 returns to the starting point, and the first hydraulic cylinder 3 drives the gradient stamping assembly 5 to rise until the pressing limit component 53 no longer presses tightly against the trapezoidal groove 6. Then, the metal sheet that has been curled and sleeved on the pressing limit component 53 is taken away horizontally. By repeating the above process, the bending and curling processes of the metal sheet are continuously completed. Using the operating table 2 as the lower die and the gradient stamping assembly 5 as the upper die, the bending and curling of the flat-top chain link plate are continuously completed using two working states of one die, eliminating the need to replace the die, reducing the time consumed for die replacement, and also reducing the possibility of inaccurate positioning after die replacement resulting in misalignment of the bending and curling positions.

[0036] In order to use one die to perform the two processes of bending and curling on the metal sheet, refer to Figure 3, the pressing limit component 53 includes an intermediate plate 531 and two cylinders 532. The intermediate plate 531 is fixedly connected to the bottom of the telescopic tube 52. The two cylinders 532 are respectively installed on both sides of the intermediate plate 531. A square block 533 is fixedly connected to the connection between the cylinder 532 and the top of the intermediate plate 531. During use, the pressing limit component 53 presses the metal sheet against the trapezoidal groove 6 to complete the fixation of the metal sheet. Then, after the bending part 54 is driven to descend, the edge of the metal sheet is squeezed against the trapezoidal groove 6 to bend the edge of the metal sheet. Then, the bending part 54 is driven to rise, and the hydraulic cylinder two 4 pushes the bent area of the metal sheet to continue to bend towards the trapezoidal groove. During the process of the metal sheet being pushed and bent by the hydraulic cylinder two 4, it is blocked by the cylinder 532, and then gradually adheres to the outside of the cylinder 532. Finally, due to the limitation of the cylinder 532, it is curled, completing the two processes of bending and curling the flat-top chain link plate. Finally, the curled flat-top chain link plate can be taken away from the pressing limit component 53.

[0037] In order to enable the gradient stamping component 5 to have two different working states, corresponding to the two processes of bending and curling the flat-top chain link plate, refer to Figure 4 , the telescopic tube 52 includes an outer tube 521, a slider 522 and a spring 523. The outer tube 521 is fixedly connected to the bottom of the mounting plate 51. The slider 522 is fixedly connected to the top of the pressing limit component 53. One end of the slider 522 extends into the outer tube 521 movably. The spring 523 is installed inside the outer tube 521.

[0038] During use, the weight of the pressing limit component 53 and the slider 522 drives the slider 522 to descend along the outer tube 521 to the lowest position, stretching the spring 523 to the maximum extent. At this time, the height of the pressing limit component 53 is lower than the height of the bending part 54. During the process of the hydraulic cylinder one 3 driving the gradient stamping component 5 to descend, the pressing limit component 53 first contacts the metal sheet in the trapezoidal groove 6 and presses the metal sheet in the trapezoidal groove 6 for fixation. Then, the hydraulic cylinder one 3 drives the gradient stamping component 5 to continue to descend, driving the mounting plate 51 and the outer tube 521 to descend, squeezing and bending the spring 523. The force of the spring 523 pushing the pressing limit component 53 downward increases, increasing the firmness of the metal sheet being pressed in the trapezoidal groove 6 until the bending part 54 gradually squeezes the edge of the metal sheet into the trapezoidal groove 6 to complete the bending process by squeezing the edge of the metal sheet into the arc of the side of the trapezoidal groove 6, forming the effect that the pressing limit component 53 and the bending part 54 contact the flat-top chain link plate successively, and using the gradient stamping component 5 to achieve two different working states to meet the requirements of the two processes of bending and curling the flat-top chain link plate.

[0039] Embodiment Two

[0040] Since the edge position of the flat-top chain link plate is always bent during processing, when the bent portion 54 and the edge position of the metal sheet are squeezed and bent, they will move relative to each other, resulting in the bent portion 54 and the metal sheet rubbing for a certain distance. Since the rubbing position is concentrated on the edge of the bent portion 54 and the metal sheet, the heat generated by the friction is relatively concentrated. In order to reduce the possibility of damage caused by heat concentration in some areas during the processing of the flat-top chain link plate, referring to Figures 1 - 4 , on the basis of the first embodiment, a first water storage tank 7 is provided inside the bent portion 54, a second water storage tank 8 is provided inside the pressing and limiting component 53, and a wear-resistant hose 9 is communicated between the bent portion 54 and the pressing and limiting component 53.

[0041] During use, the pressing and limiting component 53 is filled with water to ensure that the water does not completely submerge the square 533. The pressing and limiting component 53 first contacts the metal sheet inside the trapezoidal groove 6, presses the middle area of the metal sheet against the inner wall of the trapezoidal groove 6. At this time, the bent portion 54 is located diagonally above the pressing and limiting component 53. According to the principle of the communicating vessel, all the water is in the pressing and limiting component 53 with a lower position. Then the bent portion 54 is driven by the first hydraulic cylinder 3 to continue to descend until the bent portion 54 contacts the metal sheet and squeezes the metal sheet against the inner wall of the trapezoidal groove 6. At this time, the bent portion 54 and the pressing and limiting component 53 are at the same height. A part of the water inside the pressing and limiting component 53 flows into the inside of the bent portion 54 through the wear-resistant hose 9. The heat generated during the process of the bent portion 54 squeezing and bending the metal sheet is transferred to the water inside the bent portion 54, achieving the cooling effect on the bent portion 54 that squeezes the metal sheet to bend. When the second hydraulic cylinder 4 pushes the bent metal sheet to be curled, the edge of the metal sheet will be pushed and pressed against the cylinder 532, squeezing the wear-resistant hose 9 against the cylinder 532. The deformation ability of the wear-resistant hose 9 itself after being squeezed reduces the influence on the curling of the metal sheet.

[0042] After the metal sheet is bent and rolled, the hydraulic cylinder 1-3 drives the gradient stamping assembly 5 to rise, removes the processed metal sheet, and then places the metal sheet to be processed again at the position below the gradient stamping assembly 5 in the trapezoidal groove 6. The bending part 54 returns to the position diagonally above the pressing and limiting assembly 53 again. The water heated inside the bending part 54 flows back into the pressing and limiting assembly 53 again, and conveys the heat generated during the process of the bending part 54 squeezing the metal sheet to bend into the pressing and limiting assembly 53, so that the water inside the pressing and limiting assembly 53 is heated until the hydraulic cylinder 1-3 pushes the gradient stamping assembly 5 to descend again. When the pressing and limiting assembly 53 contacts the metal sheet inside the trapezoidal groove 6, the heat in the heated water inside the pressing and limiting assembly 53 is transferred to the middle area of the metal sheet, so that the heat of the water inside the pressing and limiting assembly 53 is dissipated more quickly, and it can absorb the heat generated during the bending process when bending the metal sheet, and then transfer the heat by using the conversion process of different processes of metal sheet processing, and transfer the heat to the unbent area when bending the metal sheet next time, so that the heat generated at the bent position of the metal sheet is evenly dispersed, reducing the possibility of damage caused by heat concentration in some areas during the processing of the flat-top chain link plate.

[0043] Embodiment III

[0044] In order to accelerate the heat dissipation rate of the water in the water storage tank 1-7 and maintain the cooling effect of the water on the position where the bending part 54 squeezes and bends the metal sheet, referring to Figures 1 - 5 , on the basis of Embodiment I, a sealing frame 10 penetrating through its interior is provided at the bottom of the pressing and limiting assembly 53. A heat conducting block 11 is slidably connected inside the sealing frame 10. An annular groove is formed at the bottom of the heat conducting block 11, and a heat insulating frame 12 is installed inside the annular groove.

[0045] During use, part of the heat generated during the process of the bending part 54 squeezing and bending the metal sheet is transferred to the water inside it, and then flows into the water storage tank 1-7 through the wear-resistant hose 9. Other heat remains at the bending part 54 and the bent position of the metal sheet, and the heat of the water in the water storage tank 1-7 is transferred to the heat conducting block 11.

[0046] Before the heat conducting block 11 presses the metal sheet, the heat conducting block 11 descends to the lowest position along the sealing frame 10 under its own gravity. At this time, a small part of the top of the heat conducting block 11 is in contact with the water inside the water storage tank 1-7. The heat in the water is transferred to the heat conducting block 11, and then the heat is dissipated into the air outside the pressing and limiting assembly 53 from one end extending out of the bottom of the heat conducting block 11 to the outside of the pressing and limiting assembly 53, continuously dissipating the heat of the water in the water storage tank 1-7 to the outside of the pressing and limiting assembly 53 when the metal sheet is not bent and rolled.

[0047] After the heat conduction block 11 extrudes the metal sheet, the heat conduction block 11 is blocked by the metal sheet and is completely pushed into the pressing limit component 53. At this time, a small part of the top area of the heat conduction block 11 rises above the water surface inside the first water storage tank 7. The area of the outer side of the heat conduction block 11 wrapped by the heat insulation frame 12 contacts the water in the first water storage tank 7. At this time, the heat in the water in the first water storage tank 7 cannot be transferred to the heat conduction block 11 through the heat insulation frame 12. The heat conduction block 11 can only transfer the heat accumulated when it contacted the water before to the metal sheet in contact with its bottom until the first hydraulic cylinder 3 drives the gradient stamping component 5 to rise to the starting point. The lower half area of the heat conduction block 11 drops outside the pressing limit component 53 again. A small part of the top area of the heat conduction block 11 is again inside the first water storage tank 7 and contacts the water, and can continuously dissipate the heat generated during the bending process to the surrounding air without bending the metal sheet, reducing the temperature of the water inside the first water storage tank 7, thereby maintaining the cooling effect on the bent position of the metal sheet, and at the same time controlling the heat transferred to the non-bent area in the middle of the metal sheet during the bending of the metal sheet, reducing the possibility of excessive heat continuously transferred to the metal sheet.

[0048] Since the heat conduction block 11 and the heat insulation frame 12 continuously rise and fall along the sealing frame 10 during the working process, there is a possibility of water leakage at the joint after long-term use. The water in the first water storage tank 7 slowly drips from the gap between the heat conduction block 11, the heat insulation frame 12 and the sealing frame 10 to the lower trapezoidal groove 6 and the metal sheet below. The heat in the water in the water storage tank is also transferred to the outside of the gradient stamping component 5 in the same way, playing a role in assisting the gradient stamping component 5 to dissipate heat. And the amount of water dripping from the gradient stamping component 5 is small and easy to volatilize, having a small impact on the processing of the flat-top chain link plate. It only requires the staff to actively replenish water into the gradient stamping component 5 at regular intervals. Therefore, the bending part 54 can select an opening position at the top for convenient water replenishment.

[0049] Embodiment Four

[0050] In order to make the feeding more stable during the processing of the flat-top chain link plate, referring to Figures 1 - 6 , on the basis of Embodiment One, a belt conveyor 13 that extends into the trapezoidal groove 6 is installed on one side of the operating table 2. A buffer component 14 is installed at the connection between the belt conveyor 13 and the trapezoidal groove 6. The buffer component 14 includes a rotating rod 141 and a rubber sheet 142. Both ends of the rotating rod 141 are rotatably connected to the inner wall of the trapezoidal groove 6. The rubber sheets 142 are equidistantly installed outside the rotating rod 141.

[0051] During use, the metal sheet is conveyed by the belt conveyor 13 directly below the gradient stamping assembly 5. When the metal sheet is conveyed from the belt conveyor 13 into the trapezoidal groove 6, the bottom of the metal sheet is supported by the rubber sheet 142, and the rubber sheet 142 is squeezed and bent for buffering, making the process of transferring the metal sheet from the belt conveyor 13 to the trapezoidal groove 6 smoother. At the same time, the metal sheet moving directly below the gradient stamping assembly 5 drives the rotating rod 141 to rotate through the rubber sheet 142. The slowly rotating rotating rod 141 and the rubber sheet 142 not only frictionally clean the lower surface of the metal sheet and the area of the trapezoidal groove 6 directly below the rubber sheet 142, but also drive the surrounding air to flow slowly, blowing away the dust inside the trapezoidal groove 6. This not only makes the process of transferring the metal sheet from the belt conveyor 13 to the trapezoidal groove 6 smoother, but also can clean the dust on the lower surface of the metal sheet during the feeding process of the metal sheet. At the same time, the air flow is used to clean the dust in the area of the trapezoidal groove 6 near the rubber sheet 142, reducing the impact of the dust settling inside the trapezoidal groove 6 on the bending of the metal sheet.

[0052] To realize the automatic feeding process for the flat-top chain link plate processing, referring to Figure 6 , a material placing frame 15 is installed on the top of the operating table 2. The top of the material placing frame 15 is open, and a plurality of metal sheets 16 are installed inside the material placing frame 15. A notch for placing the metal sheet 16 is provided on one side of the material placing frame 15 away from the operating table 2. A cross frame 17 is fixedly connected to one side of the operating table 2, and bending plates 18 are fixedly connected to both sides of the material placing frame 15. Bolts are installed between the bending plates 18 and the cross frame 17.

[0053] During use, the metal sheets 16 are stacked in the material placing frame 15, and the lowermost metal sheet 16 is in contact with the belt conveyor 13. The belt conveyor 13 continuously conveys the lowermost metal sheet 16 in the material placing frame 15 directly below the gradient stamping assembly 5. When there are fewer metal sheets inside the material placing frame 15, it is only necessary to put another stack of metal sheets into the material placing frame 15 again, and the automatic feeding process for the flat-top chain link plate processing can be completed.
