Description

Technical Field

[0001] The utility model relates to the field of punching machines, in particular to a metal mechanical punching device. Background Art

[0002] Stamping is a forming processing method, which specifically refers to applying external force to plates, strips, tubes and profiles through presses and dies to cause them to undergo plastic deformation or separation, thereby obtaining workpieces (stampings) of the desired shape and size. The stamping blanks are mainly hot-rolled and cold-rolled steel plates and strips. This processing method is often used to manufacture various metal products, such as automobile bodies, chassis, fuel tanks, radiators, boiler drums, container shells, iron core silicon steel sheets for motors and electrical appliances, etc.

[0003] Stamping processing depends on the mold. The mold is a special tool for batch processing of materials (metal or non-metal) into the required stamping parts. During the stamping process, the sheet metal is directly subjected to deformation force and deformed in the mold, thereby obtaining product parts with a certain shape, size and performance. According to the stamping temperature, it can be divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity, while the latter is carried out at room temperature and is a commonly used stamping method for thin plates.

A stamping protrusion 22 is fixedly installed on the upper surface of the first stamping seat 2 away from the stamping machine housing 1. A first groove body 23 is opened on one side of the upper surface of the first stamping seat 2, and an air gun 24 is fixedly installed inside the first groove body 23. A first pressure sensor 25 and a second pressure sensor 26 are fixedly installed on the upper surface of the first groove body 23, and the first pressure sensor 25 is electrically connected to the air gun 24. A support seat 7 is fixedly installed on one side of the stamping machine housing 1, and a plate 73 is slidably clamped on the upper surface of the support seat 7. A motor 71 is fixedly installed on one side of the upper surface of the support seat 7, and a transmission wheel 72 is fixedly installed on the driving end of the motor 71. The side surface of the transmission wheel 72 is tightly fitted with the plate 73, and the motor 71 is electrically connected to the second pressure sensor 26.

[0032] When in actual use, first energize the device, then slide the plate 73 into the upper end of the support seat 7, start the motor 71, the motor 71 drives the transmission wheel 72 to rotate, and then under the action of friction, the transmission wheel 72 drives the plate 73 to transmit, so that the plate 73 gradually moves to the bottom of the hydraulic cylinder 6, and the motor 71 works in a cycle. Each cycle of the motor 71 will drive the plate 73 to move a unit length toward the hydraulic cylinder 6. When the plate 73 moves to the bottom of the hydraulic cylinder 6, the hydraulic cylinder 6 drives the punching head 8 to descend. The descent of the punching head 8 will press the second punching seat 3 toward the direction of the first punching seat 2, and then the punching protrusion 22 will enter the third groove Inside the body 32, the punching protrusion 22 squeezes the plate 73 into the inside of the punching groove 81, and punches the workpiece into a box-shaped workpiece. At this time, the punching block 82 will punch the plate 73 into the inside of the second groove body 31 to form the edge of the box-shaped workpiece. The punching block 82 also punches and shears the plate 73. At this time, the processing of the box body is completed. When the punching head 8 descends, it will drive the punching block 83 to descend together. The punching block 83 cooperates with the punching groove 33 to realize the punching and shearing effect, and the completed plate 73 is cut into scraps, which is convenient for the subsequent removal of scraps. Considering the cost issue, the width of the punching block 83 and the plate 73 is reduced as much as possible to reduce material waste.

[0033] When the second punching seat 3 descends, the sliding ring 34 and the matching sliding column 35 will also descend accordingly. When the sliding ring 34 descends, it squeezes all the spring telescopic rods 27. At this time, the fourth gear rod 351 is blocked by the third gear rod 281, and then the fourth gear rod 351 rotates around the rotating rod 352. When the third gear rod 281 continues to rise, the third gear rod 281 is separated from the support of the fourth gear rod 351. At this time, the fourth gear rod 351 is driven to rotate in the opposite direction under the action of the torsion spring 353 until it is blocked by the block 354. At this time, if the hydraulic cylinder 6 retracts the punching head 8, the second punching seat 3 loses the pushing When the force is applied, the second punching seat 3 will move upward under the drive of the spring telescopic rod 27. At this time, the third gear rod 281 contacts the upper surface of the fourth gear rod 351, and the fourth gear rod 351 is blocked by the block 354. The matching sleeve 28 is fixedly installed on the punching machine housing 1. Then, under the continuous push of the spring telescopic rod 27, the matching slide column 35 will drive the second punching seat 3 to rotate, and drive the workpieces and scraps that have been processed thereon to rotate together. At this time, the next group of second trough bodies 31 and third trough bodies 32 will be rotated to the bottom of the hydraulic cylinder 6, so as to facilitate the machine to carry out the next cycle of work.

[0034] When the second punching seat 3 descends, it will squeeze the first pressure sensor 25 and the second pressure sensor 26. When the first pressure sensor 25 is squeezed, it will drive the air gun 24 to work. The air gun 24 will blow out compressed air to blow the completed box-shaped workpiece out of the second trough body 31. When the second pressure sensor 26 is squeezed and released, it will drive the motor 71 to work in a cycle. The motor 71 will transmit the plate 73 to realize automatic loading.

[0035] A first unloading member 4 and a second unloading member 5 are fixedly installed on the side surface of the first stamping seat 2 away from the stamping machine housing 1. The first unloading member 4 is used to unload the workpiece, and the second unloading member 5 is used to unload the scraps. The first unloading member 4 includes a first sleeve 41, and a first slide bar 42 is slidably clamped inside the upper end of the first sleeve 41. A first spring 43 is fixedly installed between the first slide bar 42 and the first sleeve 41, and a first stop bar 44 is fixedly installed on the top of the first slide bar 42. A first clamping rod 45 is fixedly installed in the middle of the first slide bar 42. The second stamping seat 3 is located between the first stop bar 44 and the first clamping rod 45, and there is a gap between the first stop bar 44 and the second stamping seat 3. The gap is not higher than the height of the workpiece, the first clamping rod 45 is in close contact with the lower surface of the second punching seat 3, the second unloading member 5 includes a second sleeve 51, and the second sleeve 51 has a second slide bar 52 slidably clamped inside the upper end, a second spring 53 is fixedly installed between the second slide bar 52 and the second sleeve 51, a second stop bar 54 is fixedly installed at the top of the second slide bar 52, and a second clamping rod 55 is fixedly installed in the middle of the second slide bar 52, the second punching seat 3 is located between the second stop bar 54 and the second clamping rod 55, the second stop bar 54 and the second clamping rod 55 are respectively attached to the upper and lower surfaces of the second punching seat 3, and the second stop bar 54 can be used to remove scraps when the second punching seat 3 rotates.

[0036] When the second stamping seat 3 descends, it will have a pushing effect on the first clamping rod 45 and the second clamping rod 55. At this time, the first spring 43 and the second spring 53 are compressed, so that the positions of the first baffle rod 44 and the second baffle rod 54 relative to the second stamping seat 3 remain almost unchanged. Because there is a gap between the first spring 43 and the second stamping seat 3, the box-shaped workpiece will be blocked by the first baffle rod 44, and the scraps will rotate from the inside of the gap to the position where the second unloading piece 5 is located. At this time, the scraps will be blocked by the second baffle rod 54. When the first baffle rod 44 and the second baffle rod 54 are both placed at an angle, the box-shaped workpiece and the scraps are respectively blocked by the first baffle rod 44 and the second baffle rod 54 and slide out of the surface of the second stamping seat 3 under the continuous rotation of the second stamping seat 3, thereby realizing the unloading of the workpiece and the scraps at different positions.

[0037] Working principle: first energize the device, then slide the plate 73 into the upper end of the support seat 7, start the motor 71, the motor 71 drives the transmission wheel 72 to rotate, and then the transmission wheel 72 drives the plate 73 to transmit under the action of friction, so that the plate 73 gradually moves to the bottom of the hydraulic cylinder 6, and the motor 71 works in a cycle. Each cycle of the motor 71 will drive the plate 73 to move a unit length toward the hydraulic cylinder 6. When the plate 73 moves to the bottom of the hydraulic cylinder 6, the hydraulic cylinder 6 works to drive the punch head 8 to descend, and the descent of the punch head 8 will move the second punch seat 3 toward the first punch seat 2 The punching block 82 presses the sheet 73 into the second slot 31 to form the edge of the box-shaped workpiece. The punching block 82 punches and shears the sheet 73 at the same time. The processing of the box body is completed at this time. When the punching head 8 descends, the punching block 83 is driven to descend together. The punching block 83 cooperates with the punching slot 33 to realize the punching and shearing effect, and the completed sheet 73 is cut into scraps.

[0038] When the second punching seat 3 descends, the sliding ring 34 and the matching sliding column 35 will also descend accordingly. When the sliding ring 34 descends, it squeezes all the spring telescopic rods 27. At this time, the fourth gear rod 351 is blocked by the third gear rod 281, and then the fourth gear rod 351 rotates around the rotating rod 352. When the third gear rod 281 continues to rise, the third gear rod 281 is separated from the support of the fourth gear rod 351. At this time, the fourth gear rod 351 is driven to rotate in the opposite direction under the action of the torsion spring 353 until it is blocked by the block 354. At this time, if the hydraulic cylinder 6 retracts the punching head 8, the second punching seat 3 loses the pushing When the force is applied, the second punching seat 3 will move upward under the drive of the spring telescopic rod 27. At this time, the third gear rod 281 contacts the upper surface of the fourth gear rod 351, and the fourth gear rod 351 is blocked by the block 354. The matching sleeve 28 is fixedly installed on the punching machine housing 1. Then, under the continuous push of the spring telescopic rod 27, the matching slide column 35 will drive the second punching seat 3 to rotate, and drive the workpieces and scraps that have been processed thereon to rotate together. At this time, the next group of second trough bodies 31 and third trough bodies 32 will be rotated to the bottom of the hydraulic cylinder 6, so as to facilitate the machine to carry out the next cycle of work.

[0039] When the second punching seat 3 descends, it will squeeze the first pressure sensor 25 and the second pressure sensor 26. When the first pressure sensor 25 is squeezed, it will drive the air gun 24 to work. The air gun 24 will blow out compressed air to blow the completed box-shaped workpiece out of the second trough body 31. When the second pressure sensor 26 is squeezed and released, it will drive the motor 71 to work in a cycle. The motor 71 will transmit the plate 73 to realize automatic loading.

[0040] When the second stamping seat 3 descends, it will have a pushing effect on the first clamping rod 45 and the second clamping rod 55. At this time, the first spring 43 and the second spring 53 are compressed, so that the positions of the first baffle rod 44 and the second baffle rod 54 relative to the second stamping seat 3 remain almost unchanged. Because there is a gap between the first spring 43 and the second stamping seat 3, the box-shaped workpiece will be blocked by the first baffle rod 44, and the scraps will rotate from the inside of the gap to the position where the second unloading piece 5 is located. At this time, the scraps will be blocked by the second baffle rod 54. When the first baffle rod 44 and the second baffle rod 54 are both placed at an angle, the box-shaped workpiece and the scraps are respectively blocked by the first baffle rod 44 and the second baffle rod 54 and slide out of the surface of the second stamping seat 3 under the continuous rotation of the second stamping seat 3, thereby realizing the unloading of the workpiece and the scraps at different positions.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
