Description

Technical Field

[0001] This application relates to the field of gasket manufacturing technology, and in particular to a gasket punching and cutting equipment. Background Technology

[0002] A washer is a part placed between a connected component and a nut. It is generally a flat metal ring used to protect the surface of the connected component from scratches by the nut and to distribute the pressure of the nut on the connected component. Washers are stamped by punching equipment during the production process.

[0003] Existing gasket punching and cutting equipment has safety hazards during use: on the one hand, metal splattering is likely to occur when punching metal sheets; on the other hand, during operation, workers need to frequently reach under the punching head to place metal sheets and remove finished parts. This working method lacks effective protection for the personal safety of operators. Therefore, an improvement is now being made to a gasket punching and cutting equipment. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a gasket punching and cutting device, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: a gasket punching and cutting device, comprising a worktable, a positioning seat fixedly installed at the center of the upper surface of the worktable, a punching die slidably inserted inside the positioning seat, a storage slot for placing metal sheets on the upper surface of the punching die, a handle fixedly connected to the front side of the punching die, a mounting frame fixedly installed on the upper surface of the worktable behind the positioning seat, a cylinder fixedly installed on the top of the mounting frame, a mounting block fixedly connected to the lower end of the cylinder passing through the mounting frame, a punching head fixedly installed on the lower surface of the mounting block, a circular hole penetrating the upper surface of the mounting block, a cylinder slidably inserted inside the circular hole, a pressure plate fixedly connected to the lower end of the cylinder, a spring sleeved on the outer wall of the cylinder, the pressure plate fixedly connected to the mounting block via the spring, and a through hole penetrating the upper surface of the pressure plate for the punching head to pass through.

[0006] By adopting the above technical solution, the cylinder moves the mounting block downwards through telescopic motion, adjusting the position of the punching head and the pressure plate. A linkage structure is formed through the cooperation between the round hole, cylinder, spring and pressure plate. During punching, the pressure plate contacts the metal sheet first and applies stable pressure to avoid material displacement or splashing. The punching head passes through the through hole to complete precise punching. The covering effect of the pressure plate significantly reduces the risk of metal fragments scattering. The punching die can be slid and pulled out through the handle. The operator can place the metal sheet and take out the finished product without putting his / her hands into the punching area. The plug-in design of the punching die and the positioning seat ensures that the processing position is fixed and completely eliminates the need for hand intervention in the dangerous area.

[0007] As a preferred technical solution of this application, an anti-detachment ring is fixedly connected to the upper end of the cylinder, and the diameter of the anti-detachment ring is larger than the diameter of the circular hole.

[0008] By adopting the above technical solution, the cylinder is prevented from detaching from the hole by setting an anti-detachment ring.

[0009] As a preferred technical solution of this application, the number of the circular holes, cylinders, springs and anti-detachment rings are all four and correspond one-to-one, and the four circular holes are evenly distributed in a linear array on the upper surface of the mounting block.

[0010] By adopting the above technical solution, the stability and accuracy of the pressure plate's movement are ensured, and the pressure plate is prevented from shifting during movement, so that the pressure plate can descend vertically and adhere to the metal sheet, making the metal sheet bear force evenly.

[0011] As a preferred technical solution of this application, the pressure plate is located directly above the punching die, and the external dimensions of the pressure plate are adapted to the internal space dimensions of the storage slot.

[0012] By adopting the above technical solution, it is ensured that the pressure plate can completely cover the metal sheet and apply stable pressure during stamping, thus avoiding material displacement or splashing.

[0013] As a preferred technical solution of this application, a magnet is embedded and installed inside the positioning seat on the rear side of the punching die, and an iron block is embedded and installed on the rear wall of the punching die, and the iron block is magnetically attracted to the magnet.

[0014] By adopting the above technical solution, when the punching die is pushed into the positioning seat, the magnet and the iron block are automatically attracted, so that the storage slot and the axis of the punching head are instantly aligned.

[0015] As a preferred technical solution of this application, the upper surface of the storage slot is provided with a punching groove for inserting a punching head, and the number of punching grooves is the same as the number of punching heads and they correspond one-to-one.

[0016] By adopting the above technical solution, the punching head is slidably inserted into the punching groove during punching, avoiding contact between the punching head and the bottom wall of the storage groove and thus protecting the punching head.

[0017] As a preferred technical solution of this application, the two outer walls of the positioning seat are symmetrically provided with track grooves, and the two outer walls of the punching die are symmetrically connected with limit rods. The outer wall of the limit rod is rotatably sleeved with a track wheel inside the track groove, and the track wheel slides inside the track groove.

[0018] By adopting the above technical solution, the track wheel rolls in the track groove, replacing the traditional sliding friction, which reduces the coefficient of friction and ensures that there is no jamming or deviation during the pulling process of the punching die. In addition, the existence of the track groove can limit the limit rod and prevent the punching die from detaching from the positioning seat during the pulling process.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, the cylinder moves the mounting block downwards through telescopic motion, adjusting the position of the punching head and the pressure plate. A linkage structure is formed by the cooperation between the round hole, the cylinder, the spring and the pressure plate. During punching, the pressure plate contacts the metal sheet first and applies stable pressure to prevent material displacement or splashing. The punching head passes through the through hole to complete precise punching. The covering effect of the pressure plate significantly reduces the risk of metal fragments scattering. The punching die can be slid and pulled out through the handle. The operator can place the metal sheet and take out the finished product without putting their hands into the punching area. The plug-in design of the punching die and the positioning seat ensures that the processing position is fixed, completely eliminating the need for hand intervention in the dangerous area.

[0020] 2. In this utility model, when the punching die is pushed into the positioning seat, the magnet and the iron block are automatically attracted, so that the storage groove and the axis of the punching head are instantly aligned; the punching head slides into the punching groove during punching, avoiding contact between the punching head and the bottom wall of the storage groove and thus protecting the punching head.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 - Figure 4 As shown, this embodiment provides a washer punching device, including a workbench 1. A positioning seat 2 is fixedly installed at the center of the upper surface of the workbench 1. A punching die 3 is slidably inserted into the positioning seat 2. A storage slot 4 for placing metal sheets is opened on the upper surface of the punching die 3. A handle is fixedly connected to the front side of the punching die 3. A mounting bracket 6 is fixedly installed on the upper surface of the workbench 1 behind the positioning seat 2. A cylinder 7 is fixedly installed on the top of the mounting bracket 6. A mounting block 8 is fixedly connected to the lower end of the cylinder 7 through the mounting bracket 6. A punching head 9 is fixedly installed on the lower surface of the mounting block 8. A circular hole 10 is opened through the upper surface of the mounting block 8. A cylinder 11 is slidably inserted into the circular hole 10. The lower end of the cylinder 11 is fixedly connected to... There is a pressure plate 12, and a spring 14 is sleeved on the outer wall of the cylinder 11. The pressure plate 12 is fixedly connected to the mounting block 8 through the spring 14. The upper surface of the pressure plate 12 has a through hole 13 for the punching head 9 to pass through. In use, the cylinder 7 moves the mounting block 8 downward by telescopic movement, and the position of the punching head 9 and the pressure plate 12 is adjusted. The linkage structure is formed by the cooperation between the round hole 10, the cylinder 11, the spring 14 and the pressure plate 12. During punching, the pressure plate 12 first contacts the metal sheet and applies stable pressure to avoid material displacement or splashing. The punching head 9 passes through the through hole 13 to complete the precise punching. The punching die 3 can be slid and pulled out by the handle. The operator can complete the placement of the metal sheet and the removal of the finished product without putting his / her hand into the punching area.

[0026] In this embodiment, as Figure 2 As shown, an anti-detachment ring 15 is fixedly connected to the upper end of the cylinder 11. The diameter of the anti-detachment ring 15 is larger than the diameter of the circular hole 10. During use, the anti-detachment ring 15 is set to ensure that the cylinder 11 will not detach from the inside of the circular hole 10.

[0027] In this embodiment, as Figure 2As shown, the number of round holes 10, cylinders 11, springs 14 and anti-detachment rings 15 are all set in four and correspond one to one. The four round holes 10 are evenly distributed in a linear array on the upper surface of the mounting block 8. During use, this ensures the stability and accuracy of the movement of the pressure plate 12, prevents the pressure plate 12 from shifting during movement, and allows the pressure plate 12 to descend vertically and adhere to the metal sheet, so that the metal sheet is subjected to uniform force.

[0028] In this embodiment, as Figure 1 , 2 As shown in Figure 3, the pressure plate 12 is located directly above the punching die 3, and the external dimensions of the pressure plate 12 are adapted to the internal space dimensions of the storage slot 4. During use, it is ensured that the pressure plate 12 can completely cover the metal sheet and apply stable pressure during punching to avoid material displacement or splashing.

[0029] In this embodiment, as Figure 4 As shown, a magnet 5 is embedded inside the positioning seat 2 on the rear side of the punching die 3, and an iron block is embedded in the rear wall of the punching die 3. The iron block and the magnet 5 are magnetically attracted to each other. When the punching die 3 is pushed into the positioning seat 2, the magnet 5 and the iron block are automatically attracted to each other, so that the storage slot 4 and the axis of the punching head 9 are instantly aligned.

[0030] In this embodiment, as Figure 1 and 3 As shown, the upper surface of the storage slot 4 is provided with a punching groove 16 for inserting the punching head 9. The number of punching grooves 16 is the same as the number of punching heads 9 and they correspond one-to-one. During use, the punching head 9 slides into the punching groove 16 during punching to avoid contact between the punching head 9 and the bottom wall of the storage slot 4 and cause damage, thus protecting the punching head 9.

[0031] In this embodiment, as Figure 3 As shown, the outer walls of the positioning seat 2 are symmetrically provided with track grooves 17, and the outer walls of the punching die 3 are symmetrically connected with limit rods 18. The outer wall of the limit rod 18 is rotatably sleeved with a track wheel 19 inside the track groove 17. The track wheel 19 slides inside the track groove 17. In use, the track wheel 19 rolls inside the track groove 17 to replace the traditional sliding friction, thereby reducing the coefficient of friction and ensuring that the punching die 3 is not stuck or deviated during the pulling process. In addition, the existence of the track groove 17 can limit the limit rod 18 and prevent the punching die 3 from detaching from the inside of the positioning seat 2 during the pulling process.

[0032] The working principle of this utility model is as follows: When using the gasket punching equipment of this application, the operator pulls the handle to overcome the magnetic force between the iron block and the magnet 5 and pulls the punching die 3 out from the inside of the positioning seat 2. After placing the metal sheet in the storage groove 4, the punching die 3 is pushed into the positioning seat 2. At this time, the magnet 5 and the iron block automatically attract each other, so that the storage groove 4 and the axis of the punching head 9 are instantly aligned. Then, the cylinder 7 is started to perform a telescopic movement to drive the mounting block 8 to move downward, which drives the punching head 9 and the pressure plate 12 to move downward to perform the punching work. During the punching, the pressure plate 12 first contacts the metal sheet and applies stable pressure to avoid material displacement or splashing. Then, the punching head 9 passes through the through hole 13 to punch the metal sheet.
