Description

Technical Field

[0001] This utility model relates to the field of disc stamping technology, specifically to an automatic stamping equipment for disc products. Background Technology

[0002] Stamping equipment, also known as a press, stamping machine, hydraulic press, or oil press, is a special type of equipment that uses a hydraulic system to drive a die to apply pressure to metal materials to achieve plastic forming. In stamping equipment, the upper die and lower die are the core components. The sheet metal is placed between the upper and lower dies. When the upper die presses down, the sheet metal will undergo plastic deformation or separation under enormous pressure. The main function of the lower die is to support the material and provide precise forming space or shearing edge.

[0003] Currently, patent publication number CN118699162B discloses a stamping die for cylindrical stamping parts, including a frame and a moving die and a fixed die disposed at the top and bottom of the frame. The fixed die includes a die base and a lifting assembly, with a rotating assembly mounted on the lifting assembly, and an ejector plate on the top of the rotating assembly. By using the rotating assembly and ejector plate, the traditional stamping die requires the entire bottom die to be rotated 180 degrees for demolding, reducing the complexity of the rotating mechanism and simplifying the structure. After the workpiece is ejected by the lifting plate, the rotation of the rotating assembly further facilitates better demolding of the workpiece.

[0004] In the aforementioned patent, the upper die and lower die work together to cut the sheet metal into circular blocks. These circular blocks then fall out through the hollow part of the lower die. However, the diameter of the hollow part of the lower die is the same as the diameter of the cut circular blocks. This can lead to the circular blocks getting stuck in the hollow part of the lower die, hindering their normal discharge, affecting subsequent operations, and reducing processing efficiency. Therefore, we propose an automatic stamping equipment for disc products to solve the aforementioned problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide an automatic stamping equipment for disc products, which solves the problem that the hollow part of the lower die has the same diameter as the iron sheet to be cut into a circular block, which may cause the circular iron sheet to get stuck in the hollow part of the lower die.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic stamping equipment for disc products, comprising: a worktable, a transmission roller rotatably connected to the surface of the worktable, a motor fixedly connected to the surface of the worktable, a support platform fixedly connected to the top of the worktable, a hydraulic cylinder fixedly connected to the top of the worktable, an upper die fixedly connected to the end of the piston rod of the hydraulic cylinder, a lower die control assembly disposed on the worktable, and a cleaning assembly disposed on the worktable; the lower die control assembly includes a pressing guide seat fixedly connected to the surface of the piston rod of the hydraulic cylinder, two half-dies symmetrically inserted into the surface of the worktable, two pairs of limiting rods fixedly connected to the surface of the worktable, two limiting sleeves fixedly connected to the surface of the half-dies, and springs sleeved on the surface of the limiting rods.

[0007] Furthermore, the end of the motor shaft is fixedly connected to the end of the transmission roller, and the piston rod of the hydraulic cylinder passes through the support platform.

[0008] Furthermore, the limiting rod passes through the limiting sleeve, and the spring is located between the limiting sleeve and the opposite surface of the worktable.

[0009] Furthermore, the cleaning assembly includes a rack fixedly connected to the surface of the pressure guide seat, a bracket fixedly connected to the surface of the worktable, a first transmission rod rotatably connected to the bracket, a first gear fixedly connected to the surface of the first transmission rod, a second bevel gear fixedly connected to the surface of the first transmission rod, a second transmission rod rotatably connected to the surface of the bracket, a third bevel gear fixedly connected to the surface of the second transmission rod, a fourth gear fixedly connected to the surface of the second transmission rod, a bearing fixedly connected to the surface of the bracket, an annular brush fixedly connected to the inner ring surface of the bearing, and a fifth gear fixedly connected to the inner ring surface of the bearing.

[0010] Furthermore, the rack and the first gear are meshed together, and the third bevel gear and the second bevel gear are meshed together.

[0011] Furthermore, the outer ring of the bearing is fixedly connected to the surface of the bracket, and the fourth gear and the fifth gear are meshed together.

[0012] Furthermore, the diameter of the inner ring of the bearing is larger than the diameter of the upper mold, and the upper mold moves through the annular brush.

[0013] Furthermore, the surface of the worktable has a square hole, and the rack is located directly above the square hole.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. By setting up a lower die control component, when the upper die is pressed down, the two lower die halves will move closer to each other under the action of the pressing guide seat to form a complete lower die, which will cooperate with the upper die to cut the sheet metal into round pieces. When the upper die is lifted, the two lower die halves move away from each other, which provides sufficient space for the round pieces to be discharged, making it easy for the round pieces between the two lower die halves to fall smoothly without being stuck by the lower die halves. This eliminates factors that interfere with the normal falling of the round pieces, thereby improving the processing efficiency of the round pieces.

[0016] Second, by setting up a cleaning component, when the upper mold moves up or down, it will drive the ring brush to rotate, which achieves the effect of cleaning metal debris on the upper mold and prevents the metal debris adsorbed on the upper mold from affecting the accuracy of cutting the disc.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described in detail below with reference to the embodiments.

[0026] Example 1, refer to Appendix Figure 1-5 As shown, in this embodiment, in order to solve the problem in the prior art where the hollow part of the lower die has the same diameter as the sheet metal to be cut into a circular shape, which may cause the circular sheet metal to get stuck in the hollow part of the lower die, this utility model discloses an automatic stamping equipment for disc products, including: a worktable 1, a transmission roller 2 rotatably connected to the surface of the worktable 1, which can place the sheet metal on the transmission roller 2 and transmit the sheet metal by rotating the transmission roller 2, a motor 3 fixedly connected to the surface of the worktable 1, which drives the transmission roller 2 to rotate, a support platform 6 fixedly connected to the top of the worktable 1, which serves as a support for the components, a hydraulic cylinder 4 fixedly connected to the top of the worktable 1, which drives other components to press down and cut, and an upper die 5 fixedly connected to the piston rod end of the hydraulic cylinder 4, which, through the cooperation of the upper die 5 and the hydraulic cylinder 4, can press down the sheet metal or other metal sheets.

[0027] Among them, the lower mold control component 8 set on the worktable 1 can facilitate the smooth falling of the cut circular pieces without them getting stuck, and the cleaning component 9 set on the worktable 1 can clean the debris remaining on the upper mold 5.

[0028] The lower die control component 8 includes a pressing guide seat 82 fixedly connected to the piston rod surface of the hydraulic cylinder 4. The pressing guide seat 82 acts as a guide for the two half-die 81 symmetrically inserted into the surface of the worktable 1 as the upper die 5 presses down and moves up. By merging the two half-die 81, a complete lower die can be formed, which can cooperate with the pressing upper die 5 to cut sheet metal into round pieces. The pressing guide seat 82 can press down to drive the two half-die 81 to merge, and the pressing guide seat 82 can move up to make the two half-die 81 move away from each other. To facilitate the falling of the disc, two pairs of limiting rods 83 are fixedly connected to the surface of the worktable 1. The limiting rods 83 can limit the direction of movement of the lower half mold 81. Two limiting sleeves 84 are fixedly connected to the surface of the lower half mold 81. The limiting sleeves 84 can limit the distance of movement of the lower half mold 81. A spring 85 is sleeved on the surface of the limiting rods 83. The spring 85 and the limiting sleeves 84 abut against the worktable 1 and the limiting sleeves 84, so that the two lower half molds 81 automatically move away from each other when the guide seat 82 is lifted, thus expanding the space for the disc to fall.

[0029] The end of the rotating shaft of the motor 3 is fixedly connected to the end of the transmission roller 2, so that the transmission roller 2 can be rotated by the motor 3. The piston rod of the hydraulic cylinder 4 passes through the support platform 6, so that the hydraulic cylinder 4 can drive the upper mold 5 to move up and down.

[0030] The limiting rod 83 passes through the limiting sleeve 84, allowing the limiting sleeve 84 to move in a fixed direction on the limiting rod 83. The spring 85 is located between the opposing surfaces of the limiting sleeve 84 and the worktable 1, so that the spring 85 can push the limiting sleeve 84 and the lower mold 81 against the worktable 1.

[0031] The cleaning assembly 9 includes a rack 91 fixedly connected to the surface of the pressing guide seat 82, which moves downward with the pressing guide seat 82; a bracket 92 fixedly connected to the surface of the worktable 1, which supports other components; a first transmission rod 93 rotatably connected to the bracket 92, which provides transmission; a first gear 94 fixedly connected to the surface of the first transmission rod 93, which rotates with the rack 91 as it moves downward; a second bevel gear 95 fixedly connected to the surface of the first transmission rod 93, which rotates with the first transmission rod 93; and a second transmission rod 96 rotatably connected to the surface of the bracket 92. 6 serves as a transmission mechanism. The third bevel gear 97 is fixedly connected to the surface of the second transmission rod 96. The second bevel gear 95 can drive the third bevel gear 97 and the second transmission rod 96 to rotate. The fourth gear 98 is fixedly connected to the surface of the second transmission rod 96. The second transmission rod 96 can drive the fourth gear 98 to rotate. The bearing 99 is fixedly connected to the surface of the bracket 92. The annular brush 991 is fixedly connected to the inner ring surface of the bearing 99. The annular brush 991 can clean the surface debris of the upper mold 5. The fifth gear 992 is fixedly connected to the inner ring surface of the bearing 99. The fourth gear 98 can drive the fifth gear 992 and the inner ring of the bearing 99 to rotate simultaneously, thereby achieving the effect of cleaning the surface debris of the upper mold 5.

[0032] Among them, the rack 91 and the first gear 94 are meshed and connected, so that the rack 91 can drive the first gear 94 to rotate when it moves up and down. The third bevel gear 97 and the second bevel gear 95 are meshed and connected, so that the rotation of the second bevel gear 95 can drive the third bevel gear 97 to rotate.

[0033] The outer ring of the bearing 99 is fixedly connected to the surface of the bracket 92, so that the outer ring of the bearing 99 cannot rotate, and only the inner ring of the bearing 99 can rotate. The fourth gear 98 and the fifth gear 992 are meshed and connected, so that when the fourth gear 98 rotates, it can drive the fifth gear 992, the inner ring of the bearing 99 and the annular brush 991 to rotate.

[0034] The inner ring of bearing 99 has a larger diameter than the upper mold 5, allowing the upper mold 5 to pass smoothly through the inner ring of bearing 99. The upper mold 5 moves through the annular brush 991, enabling the annular brush 991 to clean the upper mold 5 while facilitating its smooth passage through the annular brush 991.

[0035] The workbench 1 has a square hole 7 on its surface, which facilitates the insertion of the rack 91. This ensures that the workbench 1 does not obstruct the path of the rack 91. The rack 91 is located directly above the square hole 7, which facilitates the rack 91 passing through the workbench 1.

[0036] It should be noted that both motor 3 and hydraulic cylinder 4 are existing technologies.

[0037] Working principle: Place sheet metal or other material on workbench 1, start the transmission roller 2 to drive workbench 1 forward, start the hydraulic cylinder 4 to press down the upper mold 5. At this time, the annular brush 991 rotates as the upper mold 5 is pressed down until the upper mold 5 reaches the bottom and stops rotating; the two half lower molds 81 approach each other until they merge as the upper mold 5 and the lower guide seat 82 are pressed down.

[0038] When the guide seat 82 is pressed down, it drives the rack 91 to press down, which causes the first gear 94 to drive the first transmission rod 93 and the second bevel gear 95 to rotate, thereby driving the third bevel gear 97 and the fourth gear 98 to rotate, which causes the fifth gear 992 to drive the annular brush 991 to rotate. When the upper mold 5 passes through the bearing 99, the annular brush 991 cleans the surface of the upper mold 5.

[0039] When the limit rod 83 is pressed down, the inclined surface of the pressure guide seat 82 drives the two half-lower molds 81 to move closer to each other, so that the limit sleeve 84 squeezes the spring 85 until the two half-lower molds 81 merge together to form a complete lower mold, which cooperates with the upper mold 5 to cut the sheet metal into round pieces.

[0040] When the hydraulic cylinder 4 drives the lower guide seat 82 and the upper mold 5 to move upward, the two lower mold halves 81 move away from each other under the action of the spring 85 pushing the limit sleeve 84, which facilitates the falling of the disc. The lower guide seat 82 will drive the rack 91 to move upward together, so that the annular brush 991 rotates to clean the surface of the upper mold 5 passing through the bearing 99 again.
