Description

Technical Field

[0002] Steel belt refers to a conveyor belt made of carbon steel, used as the traction and carrying component of a belt conveyor, and also for bundling goods. It is a narrow and long steel plate produced by various steel rolling mills to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. It is characterized by high output, wide application, and numerous varieties. The punching and conveying linkage device of the steel belt punching fixture is responsible for continuously feeding the steel belt into the punching area and sending it out after punching. This is typically achieved through components such as stepper motors, guide rails, drive pulleys, and driven pulleys to ensure uniform speed conveying of the steel belt.

[0003] Operators, wearing work clothes and protective gear, proceed to the feeding station, inspect the motor drive, and, after confirming it is functioning normally, place and verify the parts in the loading area according to the production plan. When manually intervening in the feeding process, parts are carefully selected to prevent damage before being placed on the conveyor belt or guide rail. The device is activated as needed, and adjustments are made as necessary. The process is repeated after each batch is completed until the target is met.

[0004] In existing technologies, the punching devices of some steel strip punching fixtures require manual feeding during use. Operators manually push the steel strip during the punching interval, which is labor-intensive and poses safety hazards, including the risk of hands entering the die area, thus reducing the safety factor. Therefore, to address the above shortcomings, a punching and conveying linkage device for steel strip punching fixtures is proposed to solve the above problems. Utility Model Content

[0014] Through the above technical solution: the buffer assembly transmits the punching force through the connection between the fixed column and the slider, the sleeve slides along the fixed column to achieve buffering guidance, the spring provides elastic buffering force, and the components work together to absorb the punching impact, ensuring punching accuracy and equipment stability, while extending the service life of the device.

[0015] As a further description of the above technical solution:

[0016] Both of the guide components include guide plates, with adjacent sides of the two guide plates fixedly connected to the left and right sides of the slider, respectively. Guide frames are slidably connected to the outside of the guide plates, and the inside of the two guide frames are fixedly connected to the left and right ends of the processing table by bolts.

[0017] The above technical solution achieves the guidance and stable control of the slider movement by having the guide plate and slider move synchronously, the guide frame fixed to the processing table to provide a sliding track, and bolts to ensure the stability of the installation. The components work together to ensure the vertical accuracy and smooth operation of the stamping process.

[0018] As a further description of the above technical solution:

[0020] Through the above technical solution: the gears achieve synchronous rotation of the two shafts through meshing connection, and the coordinated work of each component ensures synchronous conveying of the feeding roller, while maintaining the stability and continuity of the steel strip feeding.

[0021] As a further description of the above technical solution:

[0022] The limiting mechanism includes a limiting frame, the rear side of which is fixedly connected to the front side of the support platform. A driving component is fixedly connected to the bottom side of the limiting frame. A limiting plate is fixedly connected to the bottom side of the limiting frame. A gear is rotatably connected to the right end of the limiting plate. Two connecting plates are slidably connected to the bottom side of the limiting frame. A connecting frame is fixedly connected to the outside of the connecting plate. A rack is fixedly connected to the top side of the connecting plate. A convex plate is fixedly connected to the opposite side of each of the two racks.

[0023] The above technical solution provides an installation base through a limiting frame, drives the connecting plate to move through a drive assembly, achieves transmission by meshing gear two with a rack, fixes the position of gear two with a limiting plate, enhances the structural strength of the connecting frame, restricts the displacement of the steel strip, and the coordinated work of each component achieves precise positioning and stable conveying of the steel strip, while ensuring the accuracy of the punching position and the processing quality.

[0024] As a further description of the above technical solution:

[0025] The drive assembly includes a support block, the top side of which is fixedly connected to the bottom side of the limiting frame. A hydraulic cylinder is fixedly connected to the left side of the support block. A transmission block is fixedly connected to the drive end of the hydraulic cylinder. The rear side of the transmission block is fixedly connected to the front side of one of the racks. Limit openings are provided at both the left and right ends of the limiting frame.

[0026] Through the above technical solution: the drive component is fixed on the limit frame by the support block, the hydraulic cylinder provides the driving force, the transmission block connects to the rack to realize linear motion, the limit opening guides the movement trajectory of the rack, and the components work together to realize the positioning and automatic limit of the steel strip, while ensuring the stability and continuity of the punching process.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the ratchet and ratchet are tightly engaged. Under the push of the rotating plate, the ratchet causes the ratchet to rotate in one direction. When the ratchet rotates, it drives the connected rotating shaft to rotate. The rotating shaft then causes the gear on the right end to rotate. When the two gears mesh with each other, the power is transmitted to another rotating shaft and the feeding roller. When the feeding roller rotates, the steel strip is fed forward smoothly. This achieves automatic feeding during the stamping process without the need for manual feeding, thereby improving the safety of the operation.

[0032] 2. In this utility model, the rotation of gear two drives another rack that meshes with it to move together. The two racks slide on the bottom side of the limiting frame, carrying the connecting plate and the connecting frame respectively. Finally, the clamping plate on the convex plate moves along with it, thereby achieving the function of restricting the transportation of steel strips of different widths, avoiding steel strip deviation and improving the scope of use.

[0040] 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.

[0041] Reference Figures 1 to 3This utility model provides an embodiment of a punching conveying linkage device for a steel strip punching fixture, including a processing table 1 and a support plate 4. A punching mechanism 2 is fixedly connected to the top of the processing table 1. The processing table 1 serves as the basic support structure of the entire device, providing a stable installation platform for the punching mechanism 2. The main function of the punching mechanism 2 is to perform punching operations on the steel strip to meet actual production needs. The punching mechanism 2 includes a cylinder 21, which is the power source of the punching mechanism 2. Driven by compressed air, it can generate linear motion. The top of the cylinder 21 is fixedly connected to the top of the processing table 1 and fixed by welding process to ensure that the cylinder 21 can be stably installed on the processing table 1 during operation, avoiding shaking or displacement. A slider 22 is fixedly connected to the driving end of the cylinder 21. When the cylinder 21 works, its driving end will generate linear motion, thereby driving the slider 22 to move together. Two guide components 23 are fixedly connected to the outside of the slider 22.

[0042] The function of the guide assembly 23 is to guide and restrict the movement of the slider 22. Both guide assemblies 23 include guide plates 2301. The adjacent sides of the two guide plates 2301 are fixedly connected to the left and right sides of the slider 22, so that the slider 22 drives the two guide plates 2301 to slide synchronously during the sliding process. The guide frame 2302 is slidably connected to the outside of the guide plate 2301. The guide frame 2302 provides a sliding track for the guide plate 2301. The inside of the two guide frames 2302 is fixedly connected to the left and right ends of the processing table 1 by bolts. The use of bolts for fixed connection not only ensures the connection strength between the guide frame 2302 and the processing table 1, but also facilitates installation and disassembly, and makes it convenient to maintain and replace the guide frame 2302. Two buffer assemblies 24 are fixedly connected to the bottom side of the slider 22. The main function of the buffer assembly 24 is to absorb and buffer the impact force during the stamping process, reduce damage to the equipment, and extend the service life of the equipment.

[0043] Both buffer components 24 include fixed posts 2401. The top sides of the two fixed posts 2401 are fixedly connected to the left and right ends of the bottom side of the slider 22, respectively, and are fixed by welding. This allows the slider 22 to drive the fixed posts 2401 to slide synchronously. A sleeve 2402 is slidably connected inside the fixed post 2401, so that the fixed post 2401 can slide inside the sleeve 2402 during the stamping process. A spring 2403 is sleeved on the outside of the sleeve 2402. When the fixed post 2401 slides inside the sleeve 2402, the spring 2403 will be compressed or stretched, thereby absorbing and buffering the impact force. The bottom ends of the two sleeves 2402 are fixedly connected to the left and right ends of the bottom of the processing table 1, respectively, and are fixed by welding, thereby providing support for the sleeves 2402. The bottom side of the slider 22 is fixedly connected to the stamping plate 26 through two connecting blocks 25. The connecting blocks 25 serve to connect the slider 22 and the stamping plate 26, so that the movement of the slider 22 can be accurately transmitted to the stamping plate 26.

[0044] Specifically, the main stamping is achieved by a slider 22 driven by a cylinder 21 mounted on a processing table 1. The double guide assembly 23 ensures the verticality of the stamping through the sliding cooperation between the guide plate 2301 and the guide frame 2302. The buffer assembly 24 adopts an elastic shock-absorbing structure composed of a fixed column 2401 and a spring 2403, which effectively absorbs the impact force when the stamping plate 26 is working. This device forms a collaborative working mechanism of "pneumatic drive plus mechanical guidance plus elastic buffer", which not only ensures the punching accuracy but also extends the service life of the equipment.

[0045] Reference Figure 1 , Figure 3 and Figure 4 A transmission mechanism 3 is fixedly connected to the left side of the processing table 1. The main function of the transmission mechanism 3 is to convert the motion of the stamping mechanism 2 into the conveying motion of the steel belt, realizing the linkage between punching and conveying. The transmission mechanism 3 includes a rotating plate 31 and a support platform 34. The support platform 34 provides support and a mounting platform for the transmission mechanism 3. The rear end of the rotating plate 31 is rotatably connected to the left side of the slider 22 and rotates through a pin, so that the rotating plate 31 can rotate under the drive of the slider 22. The front end of the rotating plate 31 is rotatably connected to a pawl 33 through a rotating plate 32. The rotating plate 32 serves to connect the rotating plate 31 and the pawl 33, allowing the pawl 33 to move as the rotating plate 31 rotates. The pawl 33 plays a unidirectional transmission role during the transmission process. The front side of the processing table 1 is fixedly connected to the rear side of the support table 34 by welding, thereby providing support for the support table 34. The middle part of the rotating plate 32 is rotatably connected to the left side of the support table 34 through a fixed shaft. The fixed shaft provides a center of rotation for the rotating plate 32, allowing the rotating plate 32 to rotate smoothly on the support table 34.

[0046] A gear 36 is fixedly connected to the right end of the rotating shaft 35. The two gears 36 are meshed, allowing them to transmit power and motion to each other, thus achieving the purpose of transmission. Inside the support platform 34, two feeding rollers 37 are rotatably connected via the two rotating shafts 35. The function of the feeding rollers 37 is to convey the steel belt. When the rotating shafts 35 rotate, they drive the feeding rollers 37 to rotate, thereby conveying the steel belt. The surface of the feeding rollers 37 is covered with a polyurethane rubber layer. This polyurethane rubber layer has good wear resistance and elasticity, increasing the friction between the feeding rollers 37 and the steel belt, ensuring stable conveying of the steel belt, and reducing damage to both the feeding rollers 37 and the steel belt. One of them... A ratchet 38 is fixedly connected to the left side of the rotating shaft 35. The ratchet 38 is an important one-way transmission mechanism in the transmission mechanism 3. It works in conjunction with the pawl 33 to achieve the function of one-way transmission. The ratchet 38 is made of 40Cr alloy steel and has been quenched. 40Cr alloy steel has high strength and toughness. After quenching, its hardness and wear resistance are further improved, which can meet the requirements of the ratchet 38 in the working process. The ratchet 38 has 24 teeth per revolution to ensure the conveying speed and accuracy of the steel belt. The ratchet 38 and the pawl 33 are meshed. This meshing connection allows the pawl 33 to slide unidirectionally on the ratchet 38, thereby achieving the function of one-way transmission and ensuring the one-way conveying of the steel belt.

[0047] Specifically, the transmission mechanism 3 achieves the linkage between stamping and conveying through unidirectional transmission of ratchet 38 and pawl 33. The rotating plate 31 converts the reciprocating motion of slider 22 into the swing of pawl 33, driving the 40Cr quenched ratchet 38 to rotate intermittently. The meshing structure of double gear 36 synchronously drives the polyurethane feeding roller 37 to achieve quantitative feeding of steel strip, forming a composite transmission of "crank slider 22 plus ratchet 38". The conveying step distance is controlled by the 24-tooth ratchet 38. With the high friction characteristics of polyurethane roller surface, it is ensured that the steel strip moves precisely one station after each stamping, realizing the automated collaborative operation of punching and conveying.

[0048] Reference Figure 1 , Figure 2 and Figure 5A limiting mechanism 5 is fixedly connected to the front side of the transmission mechanism 3. The main function of the limiting mechanism 5 is to limit and adjust the conveying of steel strips of different widths, ensuring that the steel strips can be accurately conveyed to the punching position. The limiting mechanism 5 includes a limiting frame 51, the rear side of which is fixedly connected to the front side of the support platform 34 by welding, thereby providing support for the limiting frame 51. A drive assembly 53 is fixedly connected to the bottom side of the limiting frame 51, which is the power source of the limiting mechanism 5. A limiting plate 54 is fixedly connected to the bottom side of the limiting frame 51 by welding, thereby providing support for the limiting plate 54. The right end of the frame is rotatably connected to a second gear 55, which is restricted by a pin, so that the limiting plate 54 provides support for the rotation of the second gear 55. The bottom side of the limiting frame 51 is slidably connected to two connecting plates 56. The limiting frame 51 restricts the connecting plates 56 so that they slide stably. The outside of the connecting plate 56 is fixedly connected to a connecting frame 57, which is fixed by welding so that the connecting plate 56 and the connecting frame 57 form an integral unit. The top side of the connecting plate 56 is fixedly connected to a rack 58. The rack 58 works with the second gear 55 to convert linear motion into rotational motion, thereby limiting and adjusting the steel belt. The drive component 53 includes a support block 5301.

[0049] The top side of the support block 5301 is fixedly connected to the bottom side of the limiting frame 51 by welding, thus providing support for the support block 5301. A hydraulic cylinder 5302 is fixedly connected to the left side of the support block 5301. The hydraulic cylinder 5302 is the power source for the drive assembly 53. Through hydraulic drive, it can generate linear motion power, thereby driving the transmission block 5303 to move. The drive end of the hydraulic cylinder 5302 is fixedly connected to the transmission block 5303. The transmission block 5303 can transmit the power of the hydraulic cylinder 5302 to the rack 58, thereby driving the connecting plate 56 to move. The rear side of the transmission block 5303 is fixedly connected to the front side of one of the racks 58. The motion of 5303 can be accurately transmitted to the rack 58. Limit openings 52 are opened at both ends of the limiting frame 51, so that the interior of the limiting frame 51 forms an active space. A convex plate 59 is fixedly connected to the far side of the two racks 58. The convex plate 59 works in conjunction with the limiting opening 52 to limit the left and right position of the steel strip. The outside of the convex plate 59 is slidably connected to the inside of the limiting opening 52, so that the convex plate 59 can slide smoothly within the limiting opening 52, thereby achieving the limiting effect on the steel strip. A clamping plate is fixedly connected to the top side of the convex plate 59. The clamping plate can clamp the steel strip and further ensure the stability of the steel strip during the conveying process.

[0050] Specifically, the steel strip is positioned by means of the limiting mechanism 5 through hydraulic drive and linkage with the gear rack 58. The hydraulic cylinder 5302 pushes the transmission block 5303 to drive the rack 58 to move linearly. Through the meshing transmission of the gear 2 55, the synchronous reverse movement of the double-sided connecting plates 56 is realized. The sliding pair formed by the convex plate 59 and the limiting opening 52 ensures that the clamping plate opens and closes in parallel, forming a coordinated adjustment of "hydraulic drive plus gear rack 58 plus bidirectional limiting". The adjustable clamping structure adapts to steel strips of different widths, realizing the positioning and stable conveying of materials during the stamping process.

[0051] Working principle: The steel strip to be processed is placed flat on the feeding roller 37. Then the stamping mechanism 2 is started, the cylinder 21 works, and then the slider 22 moves downward. Then, through the two connecting blocks 25, the stamping plate 26 is driven to stamp the steel strip. At the same time, the fixed column 2401 is driven to slide along the sleeve 2402 and squeeze the spring 2403, so that the spring 2403 can store elastic potential energy and absorb the impact force during the stamping process.

[0052] During the stamping process, the downward movement of the slider 22 also drives the rotating plate 31 to rotate. Then, the rotating plate 32 drives the pawl 33 to rotate. The pawl 33 and the ratchet 38 are tightly engaged. Under the push of the rotating plate 31, the pawl 33 causes the ratchet 38 to rotate in one direction. When the ratchet 38 rotates, it drives the connected rotating shaft 35 to rotate as well. The rotating shaft 35 then causes the right-end gear 36 to rotate. The two gears 36 mesh with each other, and the power is transmitted to another rotating shaft 35 and the feeding roller 37. When the feeding roller 37 rotates, the steel strip is fed forward smoothly. This achieves automatic feeding during the stamping process without the need for manual feeding, thereby improving the safety of the operation.

[0053] When conveying steel belts, if it is necessary to accommodate steel belts of different widths, the hydraulic cylinder 5302 is activated. The hydraulic cylinder 5302 will drive the transmission block 5303 to move. The transmission block 5303 will drive the connected rack 58 to move. The rack 58 and the second gear 55 interact to convert the linear motion into the rotation of the second gear 55. The rotation of the second gear 55 will drive another rack 58 that meshes with it to move together. The two racks 58, respectively, carry the connecting plate 56 and the connecting frame 57 to slide on the bottom side of the limiting frame 51. Finally, the clamping plate on the convex plate 59 moves along with it, so as to realize the function of restricting the transportation of steel belts of different widths, avoiding steel belt deviation and improving the scope of use.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
