Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, and more specifically, to a blanking structure for sheet metal processing. Background Technology

[0002] In sheet metal processing, stamping is a crucial step in forming the sheet metal. Currently, the problem of excess material getting stuck in the stamping hole is a prominent and urgent issue that needs to be addressed. During stamping, the punch rapidly impacts the sheet metal, causing it to plastically deform and separate under pressure, thus forming the desired shape. However, due to the difficulty in achieving an absolutely precise match between the punch and the stamping hole, and factors such as the elastic deformation and recovery of the sheet metal material during stamping, excess material generated during stamping is easily stuck in the stamping hole. Once the excess material is stuck in the stamping hole, it first severely interferes with subsequent stamping operations. When the punch continues to stamp, it needs to overcome the resistance of the excess material, which causes the pressure on the punch to far exceed its normal working load, further increasing the risk of burns. Wear and tear on the punch can lead to chipping, breakage, and other damage, significantly shortening its lifespan and increasing equipment maintenance and replacement costs. Furthermore, excess material stuck in the punching holes can affect the normal opening and closing of the die. Prolonged abnormal stress can cause loosening and deformation of the die's guiding mechanism and positioning components, leading to decreased die precision. Ultimately, this results in increased dimensional deviations in the produced sheet metal parts, making it difficult to guarantee product quality and significantly increasing the scrap rate. Moreover, to clean the excess material stuck in the punching holes, operators must frequently stop the machine and manually remove it using tools. This not only consumes a lot of time and manpower but also greatly reduces production efficiency, failing to meet the demands of efficient and continuous production in modern industry. Therefore, improvements are needed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 7 As shown, this utility model provides a blanking structure for sheet metal processing, comprising:

[0027] The fixing frame 1 has a sliding groove 2 on its outer surface;

[0028] The motion mechanism is located at the bottom of the fixed frame 1;

[0029] The motion mechanism includes a base frame 3, the top of which is fixedly connected to the bottom of a fixed frame 1. A drive motor 4 is fixedly installed at the bottom of the base frame 3. A rotating shaft 5 is fixedly sleeved at the other end of the output shaft of the drive motor 4. A rotating block 6 is fixedly sleeved on the outer surface of the rotating shaft 5. A fixed block 7 is abutted on the outer surface of the rotating block 6. A moving mold 8 is fixedly installed at the top of the fixed block 7. Movable blocks 29 are fixedly installed on both the left and right sides of the moving mold 8. The outer surface of the movable blocks 29 is slidably connected to the inside of the slide groove 2. Limit rods 9 are movably sleeved on the inside of both the left and right sides of the back of the moving mold 8. A spring 11 is fixedly installed at the front end of the limit rod 9. The front end of the spring 11 is fixedly connected to the inside of the moving mold 8. A stationary mold 10 is fixedly installed at the rear end of the limit rod 9. The front of the stationary mold 10 is in contact with the back of the moving mold 8. The outer surface of the stationary mold 10 is fixedly connected to the outer surface of the fixed frame 1.

[0030] When the drive motor 4 runs, the rotating shaft 5 will drive the rotating block 6 to rotate. Due to the elliptical design of the rotating block 6, the rotating block 6 will gradually release the squeezing and pushing of the fixed block 7 when it rotates. Due to the design of the spring 11, the moving mold 8 will move under the elastic force of the spring 11. Due to the limitation of the movable block 29 inside the slide 2, the moving mold 8 will drive the two movable blocks 29 to move forward along the inside of the two slide 2. At the same time, the moving mold 8 will move forward along the outer surface of the two limit rods 9. Due to the design of the two limit rods 9, the movement of the moving mold 8 will be more stable. When the moving mold 8 moves forward, the distance between it and the stationary mold 10 will increase, so that the excess material stuck between the stationary mold 10 and the moving mold 8 can fall down, thereby preventing the sheet metal excess material from getting stuck in the stamping hole. When the rotating block 6 continues to rotate, it will squeeze and push the fixed block 7 again, so that the moving mold 8 will move backward to reset.

[0031] The bracket 12 is fixedly installed on the outer surface of the fixed frame 1, the top of the bracket 12 is fixedly installed with a cylinder 13, and the output end of the cylinder 13 is fixedly installed with a punch 14.

[0032] When the cylinder 13 is running, it will drive the punch 14 to move up and down. When the punch 14 moves down and comes into contact with the sheet metal part, it will cooperate with the moving mold 8 and the stationary mold 10 to perform punching operations on the sheet metal part.

[0033] The bottom of the fixing frame 1 is fixedly installed with a base 15, and a reinforcing rod 16 is provided on the base 15.

[0034] Due to the design of the base 15, it will provide good support for the entire fixed frame 1, and due to the design of the reinforcing rod 16, it will enhance the structural strength of the base 15.

[0035] The bottom of the static mold 10 is fixedly installed with a fixed box 17, and a collection box 18 is movably connected inside the fixed box 17.

[0036] Thanks to the design of the collection box 18, it will be able to collect the scrap material from the sheet metal punching.

[0037] The fixed frame 1 has a double-acting screw 19 inside, and a driven wheel 20 is fixedly sleeved at the rear end of the double-acting screw 19. A slider 21 is threadedly sleeved on the outer surface of the double-acting screw 19. The slider 21 is slidably connected to the inside of the fixed frame 1. A clamping plate 22 is fixedly installed on the outer surface of the slider 21. There are two clamping plates 22. The bottom ends of the two clamping plates 22 are respectively attached to the top ends of the moving mold 8 and the stationary mold 10.

[0038] When the driven wheel 20 rotates, it will drive the bidirectional screw 19 to rotate. Since the slider 21 is threadedly connected to the outer surface of the bidirectional screw 19, when the bidirectional screw 19 rotates, it will drive the two sets of sliders 21 to move towards each other along the inside of the fixed frame 1. At this time, the two clamping plates 22 will move towards each other under the drive of the two sets of sliders 21. Then, the two clamping plates 22 will clamp and fix the sheet metal parts in the opposite direction.

[0039] The mounting bracket 1 has a mounting plate 23 fixedly installed on its back side. The mounting plate 23 has a power motor 24 fixedly installed on its back side. The other end of the output shaft of the power motor 24 is fixedly sleeved with a rotating shaft 25. The front end of the rotating shaft 25 is fixedly installed with a drive wheel 26. The drive wheel 26 is connected to the driven wheel 20 through a transmission belt 27.

[0040] When the power motor 24 is running, the rotating shaft 25 will drive the drive wheel 26 to rotate. At this time, the drive wheel 26 will drive the two driven wheels 20 to rotate through the transmission belt 27.

[0041] The outer surface of the transmission belt 27 is tensioned with a tensioning wheel 28, and the front of the tensioning wheel 28 is fixedly connected to the back of the fixing frame 1.

[0042] Due to the design of the tensioner 28, the contact area between the transmission belt 27 and the drive wheel 26 can be increased, thereby ensuring the stability of the transmission belt 27.

[0043] Working principle and usage process of this utility model:

[0044] First, the operator places the sheet metal part on top of the moving mold 8 and the stationary mold 10. Then, the operator starts the power motor 24. At this time, the rotating shaft 25 drives the drive wheel 26 to rotate. Subsequently, the drive wheel 26 drives the two driven wheels 20 to rotate through the transmission belt 27. At this time, the two driven wheels 20 are driven by the two bidirectional screws 19 to rotate inside the fixed frame 1. Since the outer surface of the bidirectional screws 19 is threaded with the inner thread of the slider 21, when the two bidirectional screws 19 rotate, they will drive the two sets of sliders 21 to move. Since the outer surface of the two sets of sliders 21 is slidably connected to the inside of the fixed frame 1, the two sets of sliders 21 will move towards each other along the inside of the fixed frame 1 under the drive of the two bidirectional screws 19. At this time, the two clamping plates 22 will move towards each other under the drive of the two sets of sliders 21. Then, the two clamping plates 22 will contact the sheet metal part during the opposite movement, and the two clamping plates 22 will fix the sheet metal part, thus realizing the function of conveniently clamping and fixing the sheet metal part.

[0045] The operator then activates cylinder 13, causing punch 14 to move downwards. When the bottom of punch 14 contacts the sheet metal part, it works with moving die 8 and stationary die 10 to punch the sheet metal part. During this process, excess sheet metal material falls through the gap between moving die 8 and stationary die 10 and eventually falls into the collection box 18 for collection. After the punching operation is completed, the operator activates cylinder 13 again to reset punch 14 upwards. If excess sheet metal material gets stuck between moving die 8 and stationary die 10, the operator activates drive motor 4. The rotating shaft 5 then drives rotating block 6 to rotate. Because rotating block 6 has an elliptical design, when rotating block... When rotating, the squeezing and pushing action on the fixed block 7 will be gradually released. Due to the elastic force of the spring 11, the moving mold 8 will move under the drive of the spring 11. At this time, the moving mold 8 will drive the two movable blocks 29 to move forward along the inside of the two sliding grooves 2. During this process, the distance between the moving mold 8 and the stationary mold 10 will increase, so that the excess material stuck in the gap between the stationary mold 10 and the moving mold 8 can fall under the action of gravity, thereby realizing the function of preventing the sheet metal excess material from getting stuck in the stamping hole. When the rotating block 6 continues to rotate, the rotating block 6 will squeeze and push the fixed block 7 again, so that the moving mold 8 will be reset backward, so that the back of the moving mold 8 is in contact with the front of the stationary mold 10.
