[0024] 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.
[0025] Please see Figure 1-5 The present invention provides the following technical solution:
[0026] A positioning and measuring device for free forging punching includes a base plate 1, a material positioning component 2 is provided on the top of the base plate 1, a material platform 3 is provided inside the material positioning component 2, a material to be punched 4 is placed on the top of the material platform 3, and a die positioning component 5 is provided on the right side of the top of the base plate 1.
[0027] The die positioning assembly 5 includes a telescopic rod 51, the bottom of which is bolted to the top of the base plate 1. A horizontal block 52 is bolted to the top of the telescopic rod 51. A sliding groove 53 is provided inside the horizontal block 52. A first slider 54 and a second slider 55 are slidably arranged inside the sliding groove 53. A telescopic clamping rod 56 is bolted to the top of both the first slider 54 and the second slider 55. An anti-slip clamping block 57 is bolted to the left side of the opposite side of the two telescopic clamping rods 56. A punching die 58 is clamped between the two anti-slip clamping blocks 57. The bottom of the punching die 58 is in contact with the top of the material 4 to be punched.
[0028] In this embodiment: First, the substrate 1 is placed stably on the ground of the processing area. The substrate 1 serves as the basic support component of the entire device, providing a stable platform for subsequent material positioning and die positioning. Next, the material platform 3 is placed inside the material positioning component 2, and then the material 4 to be punched is placed on the top of the material platform 3. After the material positioning component 2 positions the material, the die positioning component 5 is operated. The bottom of the telescopic rod 51 is bolted to the top of the substrate 1. On the horizontal block 52 at the top of the telescopic rod 51, the first slider 54 and the second slider 55 slide in the sliding groove 53. By adjusting the distance between the first slider 54 and the second slider 55, the anti-slip clamps 57 on the two telescopic clamping rods 56 are brought closer together, clamping the punching die 58. Finally, the height of the telescopic rod 51 is adjusted, and the length of the telescopic clamping rod 56 is adjusted so that the bottom of the punching die 58 contacts the top of the material 4 to be punched, completing the positioning before punching.
[0029] Specifically, such as Figure 3 As shown, the material positioning assembly 2 includes four telescopic hydraulic cylinders 21 arranged in a ring, with the bottom of the telescopic hydraulic cylinders 21 bolted to the top of the base plate 1.
[0030] Specifically, such as Figure 3 As shown, a positioning ring 22 is bolted between the tops of the four telescopic hydraulic cylinders 21, and four mounting blocks 23 are bolted to the top of the positioning ring 22 in a ring shape.
[0031] Specifically, such as Figure 3 As shown, the mounting block 23 is equipped with telescopic electric cylinders 24 inside, and the telescopic ends of the four telescopic electric cylinders 24 respectively contact the surface of the material 4 to be punched.
[0032] In this embodiment: after the material 4 to be punched is placed on the material table 3, the material positioning component 2 is used for positioning and measurement. The bottoms of the four circularly distributed telescopic hydraulic cylinders 21 are firmly bolted to the top of the base plate 1. When the telescopic hydraulic cylinders 21 are activated, they extend upwards, causing the positioning ring 22 to rise. The four mounting blocks 23, which are circularly bolted to the top of the positioning ring 22, also rise to a suitable height to accommodate the size of the material 4 to be punched. Subsequently, the telescopic electric cylinders 24 inside the mounting blocks 23 begin to work, and the extension of the four telescopic electric cylinders 24... The retractable ends extend and contact the surface of the material to be punched 4. By precisely controlling the extension and retraction of the telescopic electric cylinders 24, the material to be punched 4 is pushed from different directions. For example, if the material to be punched 4 is positioned to the left on the material table 3, the extension of the telescopic electric cylinder 24 on the left side is smaller than that on the right side, thus pushing the material to the right until the material to be punched 4 is centered at the top of the material table 3. At the same time, based on the extension and retraction of the four telescopic electric cylinders 24, the size of the material to be punched 4 can be accurately determined, providing accurate data support for subsequent punching operations.
[0033] Specifically, such as Figure 4 As shown, a positive and negative threaded rod 6 is threaded between the interior of the first slider 54 and the second slider 55. The positive and negative threaded rod 6 is rotatably connected to the horizontal block 52 on the side near the inner wall of the horizontal block 52. The right side of the positive and negative threaded rod 6 extends to the right side of the horizontal block 52 and is bolted to the first turntable 7.
[0034] Specifically, such as Figure 4 As shown, a limiting groove 8 is provided on the surface of the telescopic rod 51, a positioning slip ring 9 is slidably sleeved on the surface of the telescopic rod 51, a positioning pin 10 is bolted to the bottom of the positioning slip ring 9, a positioning hole 11 is provided inside the telescopic rod 51, and the surface of the positioning pin 10 contacts the inner wall of the positioning hole 11.
[0035] In this embodiment: After the punching die 58 is installed on the device, in order to ensure the accurate positioning of the punching die 58, it is necessary to operate the components related to the first slider 54, the second slider 55, and the telescopic rod 51. The worker rotates the first turntable 7. Since the first slider 54 and the second slider 55 are internally connected by a threaded rod 6, and the side of the threaded rod 6 near the inner wall of the horizontal block 52 is rotatably connected to the horizontal block 52, the rotation of the first turntable 7 drives the threaded rod 6 to rotate. According to the thread characteristics of the threaded rod 6, the first slider 54 and the second slider 55 move towards or away from each other in the sliding groove 53 of the horizontal block 52. When it is necessary to clamp the punching die 58, the worker rotates the first turntable 7 clockwise, and the first slider 54 and the second slider 55 move towards each other and are installed on the telescopic clamping rod 56. The anti-slip clamp 57 tightly clamps the punching die 58. When the die needs to be changed, the first turntable 7 is rotated counterclockwise, the first slider 54 and the second slider 55 move in opposite directions, and the anti-slip clamp 57 releases the die. Then, in order to make the horizontal angle of the telescopic clamp 56 aligned with the center of the material table 3, the worker slides the positioning slip ring 9 fitted on the surface of the telescopic round rod 51. The limiting groove 8 opened on the surface of the telescopic round rod 51 provides guidance for the sliding of the positioning slip ring 9 and enables the positioning slip ring 9 to rotate when the telescopic end of the telescopic rod rotates. When the positioning slip ring 9 slides to the appropriate position, the positioning pin 10 at the bottom of the positioning slip ring 9 is inserted into the corresponding positioning hole 11 inside the telescopic round rod 51, so that the telescopic clamp 56 is accurately aligned with the center of the material table 3, thereby ensuring the accurate positioning of the clamped punching die 58.
[0036] Specifically, such as Figure 4 As shown, the material platform 3 has a demolding hole 12 inside, and four support legs 13 are bolted to the bottom of the material platform 3. The bottom of the support legs 13 is in contact with the top of the substrate 1.
[0037] Specifically, such as Figure 1 , Figure 5As shown, a first bubble level observation block 14 is bolted to the front side of the top of the substrate 1, and a second bubble level observation block 15 is bolted to the right side of the top of the substrate 1. Threaded holes 16 are provided on the front and rear sides of both sides inside the substrate 1. An adjustment column 17 is threadedly connected inside the threaded hole 16, and a second turntable 18 is bolted to the top of the adjustment column 17.
[0038] In this embodiment: During the installation and debugging of the device, the adjustment of the level of the material platform 3 and the substrate 1 is very important. The bottom of the material platform 3 is in contact with the top of the substrate 1 through four support feet 13. The material platform 3 has a demolding hole 12 inside, which facilitates the discharge of waste material and the removal of the punching die 58 during the punching process. In order to ensure that the substrate 1 is in a level state, the worker observes the first bubble level observation block 14 on the front side of the top of the substrate 1 and the second bubble level observation block 15 on the right side. If the bubble in the first bubble level observation block 14 is biased to one side, it means that the substrate 1 is not level in the front-back direction; if the bubble in the second bubble level observation block 15 is biased to one side, it means that the substrate 1 is not level in the front-back direction. If plate 1 is not horizontal in the left-right direction, the worker rotates the second turntable 18 on the top of the adjusting column 17. Since the adjusting column 17 is threadedly connected to the threaded holes 16 on the front and rear sides of the inner side of the substrate 1, rotating the second turntable 18 will cause the adjusting column 17 to move up and down in the threaded holes 16. For example, if the front end of the substrate 1 is low, the worker rotates the second turntable 18 on the adjusting column 17 at the front end clockwise to raise the adjusting column 17, thereby raising the front end of the substrate 1 until the bubbles in the first bubble level observation block 14 and the second bubble level observation block 15 are in the center position, ensuring that the substrate 1 is in a horizontal state, thus ensuring the accurate operation of the entire free forging punching positioning and measuring device.
[0039] Working principle: First, the substrate 1 is placed stably on the processing area floor, serving as the basic support component of the entire device. The levelness of the substrate 1 is determined by observing the first bubble level observation block 14 on the front side of the top of the substrate 1 and the second bubble level observation block 15 on the right side. If the bubble in the first bubble level observation block 14 is biased to one side, it indicates that the substrate 1 is not level in the front-to-back direction; if the bubble in the second bubble level observation block 15 is biased to one side, it indicates that it is not level in the left-to-right direction. At this time, the second turntable 18 on the top of the adjusting column 17 is rotated. Since the adjusting column 17 is threadedly connected to the threaded holes 16 on the front and rear sides of the substrate 1, rotating the second turntable 18 allows the adjusting column 17 to move up and down within the threaded holes 16, thereby adjusting the substrate. 1. Horizontally, until both bubble levels are centered. Then, place the material platform 3 inside the material positioning assembly 2 on top of the substrate 1 via four bottom support feet 13. The demolding hole 12 inside the material platform 3 facilitates waste material discharge and mold removal during punching. Place the material to be punched 4 on top of the material platform 3, and then activate the material positioning assembly 2 for positioning and measurement. Four telescopic hydraulic cylinders 21, arranged in a ring and firmly bolted to the top of the substrate 1 at the bottom, extend upwards, driving the positioning ring 22 and four mounting blocks 23, bolted in a ring at the top of the positioning ring 22, to rise to a suitable height to accommodate the material size. The telescopic electric cylinders 24 inside the mounting blocks 23 operate, and the telescopic ends of the four telescopic electric cylinders 24 extend towards the material surface. The material is pushed from different directions by precisely controlling the extension and retraction amount. If the material is biased to the left, the extension amount of the left telescopic cylinder 24 is less than that of the right side, pushing the material to the right until it is centered on the top of the material platform 3. At the same time, the size of the material is judged based on the extension and retraction amount of the telescopic cylinder 24. Then, the hole mold positioning component 5 is operated. The bottom of the telescopic round rod 51 is bolted to the top of the base plate 1. The first slider 54 and the second slider 55 on the top horizontal block 52 slide in the sliding groove 53. The worker rotates the first turntable 7, which drives the positive and negative threaded rod 6, which is threaded to the first slider 54 and the second slider 55 and is rotatably connected to the horizontal block 52, to rotate, so that the first slider 54 and the second slider 55 move towards or away from each other in the sliding groove 53 of the horizontal block 52. When the first turntable 7 is rotated clockwise, the first slider 54 and the second slider 55 move towards each other, and the anti-slip clamp 57 on the telescopic clamp 56 clamps the punching die 58; rotating counterclockwise releases the die. To align the telescopic clamp 56 horizontally with the center of the material table 3, the worker slides the positioning slip ring 9 fitted on the surface of the telescopic round rod 51. The limiting groove 8 on the surface of the telescopic round rod 51 guides its sliding and allows it to rotate when the telescopic end of the telescopic rod rotates. After the positioning slip ring 9 slides to the appropriate position, the bottom positioning pin 10 is inserted into the corresponding positioning hole 11 of the telescopic round rod 51. Finally, the height of the telescopic round rod 51 and the length of the telescopic clamp 56 are adjusted so that the bottom of the punching die 58 contacts the top of the material 4 to be punched, completing the positioning before punching.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
