Description

Technical Field

[0001] This application relates to the field of metal stamping technology, specifically to a material conveying device for stamping equipment. Background Technology

[0002] In automated metal stamping production, the precise and stable conveying of continuous strip is crucial. During the conveying process, the strip is prone to lateral deviation (deviation) due to factors such as uneven tension, guide gaps, and equipment vibration.

[0003] Slight misalignment can lead to inaccurate stamping position and produce scrap; severe misalignment may damage the mold or equipment.

[0004] In existing technologies, commonly used correction devices mostly employ photoelectric sensors to detect offsets, and then use servo motors to drive the correction mechanism for adjustment. This results in complex structures, high costs, and relatively cumbersome maintenance. For small and medium-sized stamping equipment or applications requiring moderate precision (±0.1mm), a simpler and more reliable conveying positioning and correction solution is needed. Summary of the Invention

[0005] Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this application provides a material conveying device for stamping equipment, which has a simple structure and high reliability in conveying positioning and correction functions, thus solving the problems mentioned in the background technology.

[0007] To achieve the above objectives, this application provides the following technical solution: a material conveying device for a stamping equipment, comprising an equipment body, a material conveying assembly, and a stamping assembly. The material conveying assembly includes a base plate fixedly connected to one side of the equipment body. Conveying rollers are installed on both sides of the upper surface of the base plate. A sprocket is fixedly connected to one end of each of the two conveying rollers. A chain and a servo motor are provided above the base plate. The two sprockets are connected by chain drive. The output shaft end of the servo motor is fixedly connected to the rotating shaft end of the corresponding conveying roller.

[0008] A bracket is fixedly connected to the upper surface of the base plate, and cylinders are fixedly connected to both sides of the inner wall of the bracket. V-shaped guide grooves are fixedly connected to the output ends of the two cylinders, and movable pressure rollers are provided on both sides of the bracket.

[0009] The above scheme utilizes symmetrically arranged V-shaped guide grooves with their inclined surface structure to automatically apply a reverse force for mechanical correction when the material belt deviates, ensuring that the material belt is conveyed in the center. At the same time, the lower pressure rollers, which are set in the mounting grooves and flexibly supported, press the material belt to ensure effective traction of the conveyor rollers and ensure stable conveying of the material belt. In addition, the conveyor roller group, which is precisely driven by a servo motor and driven by sprockets and chains, ensures the accuracy of the material belt step conveying. The overall structure is composed of basic mechanical components, and the convenient adjustment of the position of the V-shaped guide grooves by the cylinder significantly improves the stability and reliability of the device. Ultimately, it realizes a material belt conveying system that is simple in structure, low in cost, and has efficient automatic correction and precise positioning functions.

[0010] Furthermore, the two V-shaped guide grooves are symmetrically distributed on both sides above the base plate, and the two V-shaped guide grooves are located between the two conveying rollers.

[0011] The above scheme defines the position of the V-shaped guide groove. When the material belt deviates, the inclined surface of the V-shaped guide groove on the deviated side will generate a reverse force on the edge of the material belt, forcing the material belt to move towards the center line of the V-shaped guide groove, thereby achieving the effect of automatic centering and correction and providing good self-centering capability.

[0012] Furthermore, connecting plates are fixedly connected to both sides of the bracket, and two telescopic rod assemblies are fixedly connected to the bottom surface of each connecting plate. Each connecting plate has a mounting groove at its bottom, and the upper surfaces of the two mounting grooves are fixedly connected to the bottom ends of the four telescopic rod assemblies respectively.

[0013] The above solution allows the installation groove to move slightly in the vertical direction via the telescopic rod assembly, thus enabling flexible adaptation to the conveying operation of the material belt.

[0014] Furthermore, each of the mounting grooves has a lower pressure roller rotatably mounted on its inner wall, and the positions of the two lower pressure rollers correspond to the positions of the two conveying rollers, respectively.

[0015] The above scheme uses a pressure roller to flatten and convey the material belt, thus optimizing the actual conveying quality of the material belt.

[0016] Furthermore, each of the telescopic rod assemblies is fitted with a telescopic spring on its exterior, and the two ends of the four telescopic springs are respectively fixedly connected to the outer surfaces of the two connecting plates and the two mounting grooves.

[0017] The above solution allows the lower pressure roller to move flexibly by means of a telescopic spring, and when combined with the conveyor roller, it enables more stable conveying of the material belt.

[0018] Furthermore, a diagonal brace is fixedly connected to one side of the outer surface of the device body, and the top of the diagonal brace is fixedly connected to the bottom surface of the base plate.

[0019] The above solution improves the stability of the base plate installation by using inclined bracing plates, thereby ensuring stable operation of the conveyor belt.

[0020] Furthermore, the stamping assembly includes a stamping machine body installed on top of the equipment body, an upper die installed at the bottom end of the stamping machine body, a base fixedly connected to the inner wall of the equipment body, and a lower die corresponding to the upper die installed on the upper surface of the base.

[0021] The above solution allows for stable stamping of the conveyor belt by the conveyor belt assembly through the setting of a stamping component, which is convenient to use.

[0022] Furthermore, a waste discharge plate is installed at the output end of the stamping assembly, and a controller is installed on the outer surface of the equipment body. The electrical components inside the equipment body, the material conveying assembly, and the stamping assembly are all electrically connected to the controller.

[0023] The above scheme allows for convenient directional conveying of the waste strip after stamping via a waste discharge plate, and the controller enables easy control of the electrical components in the equipment to operate one by one, making it more practical.

[0024] Beneficial effects

[0025] This stamping equipment's strip conveyor device utilizes symmetrically arranged V-shaped guide grooves with their inclined structure to automatically apply a reverse force for mechanical correction when the strip deviates, ensuring the strip is conveyed in the center. Simultaneously, a lower pressure roller, flexibly supported by a telescopic spring and positioned within an installation groove, presses the strip to ensure effective traction on the conveyor rollers while maintaining stable conveying. A conveyor roller assembly, precisely driven by a servo motor and transmitted via sprockets and chains, ensures the accuracy of the strip's step-by-step conveying. The overall structure comprises basic mechanical components, and the convenient adjustment of the V-shaped guide groove position using cylinders significantly improves the device's stability and reliability. Ultimately, this achieves a simple, low-cost strip conveyor with efficient automatic correction and precise positioning functions. Attached Figure Description

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Please see Figure 1 , Figure 4 and Figure 5 This embodiment of a stamping equipment includes a material conveying device for a stamping machine, comprising a machine body 1, a material conveying assembly 2, and a stamping assembly 3. The material conveying assembly 2 includes a base plate 201 fixedly connected to one side of the machine body 1. Conveying rollers 202 are installed on both sides of the upper surface of the base plate 201. A sprocket 203 is fixedly connected to one end of each of the two conveying rollers 202. A chain 204 and a servo motor 205 are provided above the base plate 201. The two sprockets 203 are connected by the chain 204. The output shaft end of the servo motor 205 is fixedly connected to the rotating shaft end of the corresponding conveying roller 202. When the servo motor 205 starts, it will first drive the corresponding conveying roller 202 to rotate, and then drive the sprocket 203 on the corresponding conveying roller 202 to rotate. Then, the chain 204 drives the sprocket 203 on the other side to rotate, and finally realizes that the two conveying rollers 202 rotate in the same direction, thus completing the conveying of the material belt.

[0035] Please see Figure 3 , Figure 4 and Figure 5A bracket 206 is fixedly connected to the upper surface of the base plate 201. Cylinders 207 are fixedly connected to both sides of the inner wall of the bracket 206. V-shaped guide grooves 208 are fixedly connected to the output ends of the two cylinders 207. The two V-shaped guide grooves 208 are symmetrically distributed on both sides above the base plate 201 and are located between the two conveying rollers 202, which limits the position of the V-shaped guide grooves 208. When the material belt deviates, the inclined surface of the V-shaped guide groove 208 on the deviated side will generate a reverse force on the edge of the material belt, forcing the material belt to move towards the center line of the V-shaped guide groove 208, realizing the effect of automatic centering and correction, and providing good self-centering capability. When the cylinder 207 is started, the position of the V-shaped guide groove 208 can be adjusted. By adjusting the position of the two V-shaped guide grooves 208, the centering and conveying requirements of different material belts can be met.

[0036] Please see Figure 3 , Figure 4 and Figure 5 The bracket 206 has movable lower pressure rollers 212 on both sides, and connecting plates 209 are fixedly connected to both sides of the bracket 206. Two telescopic rod assemblies 210 are fixedly connected to the bottom surface of each connecting plate 209. Each connecting plate 209 has a mounting groove 211 at its bottom. The upper surfaces of the two mounting grooves 211 are fixedly connected to the bottom ends of the four telescopic rod assemblies 210 respectively. The telescopic rod assemblies 210 can make the mounting grooves 211 move slightly in the vertical direction, so as to flexibly adapt to the conveying of the material belt. The inner wall of each mounting groove 211 is rotatably fitted with a lower pressure roller 212. The positions of the two lower pressure rollers 212 correspond to the positions of the two conveying rollers 202 respectively. The lower pressure rollers 212 can flatten and convey the material belt, thus optimizing the actual conveying quality of the material belt.

[0037] Please see Figure 3 , Figure 4 and Figure 5 Each telescopic rod assembly 210 is fitted with a telescopic spring 213. The two ends of the four telescopic springs 213 are fixedly connected to the outer surfaces of the two connecting plates 209 and the two mounting grooves 211, respectively. The telescopic springs 213 enable the lower pressure roller 212 to move flexibly and, in conjunction with the conveying roller 202, enable more stable conveying of the material belt. A diagonal brace 214 is fixedly connected to one side of the outer surface of the equipment body 1. The top of the diagonal brace 214 is fixedly connected to the bottom surface of the base plate 201. The diagonal brace 214 improves the stability of the base plate 201 installation, thereby enabling stable conveying of the material belt.

[0038] Please see Figure 1 , Figure 2 and Figure 3The stamping assembly 3 includes a stamping machine body 301 installed on top of the equipment body 1. An upper mold 302 is installed at the bottom of the stamping machine body 301. A base 303 is fixedly connected to the inner wall of the equipment body 1. A lower mold 304 corresponding to the upper mold 302 is installed on the upper surface of the base 303. By setting the stamping assembly 3, the material belt conveyed by the material belt conveying assembly 2 can be stably stamped, which is convenient to use. A waste discharge plate 4 is installed at the output end of the stamping assembly 3. A controller 5 is installed on the outer surface of the equipment body 1. The electrical components inside the equipment body 1, the material belt conveying assembly 2 and the stamping assembly 3 are all electrically connected to the controller 5. The waste discharge plate 4 can be used to conveniently convey the waste material belt after stamping. The controller 5 can be used to conveniently control the electrical components in the equipment to work one by one, which is more practical.

[0039] In this embodiment, a material conveying device for a stamping equipment utilizes symmetrically arranged V-shaped guide grooves 208 with their inclined surface structure to automatically apply a reverse force for mechanical correction when the material belt deviates, ensuring that the material belt is conveyed in the center. At the same time, in conjunction with the lower pressure roller 212, which is set in the mounting groove 211 and flexibly supported by the telescopic spring 213, the material belt is pressed to ensure the effective traction force of the conveying roller 202 while ensuring stable material belt conveying. The conveying roller 202 group, precisely driven by the servo motor 205 and transmitted through the sprocket 203 and chain 204, ensures the accuracy of the material belt step conveying. The overall structure consists of basic mechanical components such as the base plate 201, bracket 206, connecting plate 209, telescopic rod assembly 210, and inclined support plate 214. Combined with the convenient adjustment of the position of the V-shaped guide grooves 208 by the cylinder 207, the stability and reliability of the device are significantly improved, ultimately realizing a material belt conveying device with simple structure, low cost, and efficient automatic correction and precise positioning functions.

[0040] The working principle of the above embodiment is as follows: The material belt first enters between the V-shaped guide grooves 208 symmetrically arranged on both sides above the base plate 201. When the material belt deviates laterally during the conveying process, its edge will contact the inclined surface of the V-shaped guide groove 208 on the deviated side. The reverse force generated by the inclined surface automatically pushes the material belt back to the center line, realizing mechanical correction and centering guidance. After initial centering, the material belt is then conveyed by the conveyor roller 202, which is precisely driven by the servo motor 205 and rotated through the sprocket 203 and chain 204. The upper surface of the material belt is flexibly held by the lower pressure roller 212, which is installed in the mounting groove 211 and can float. The lower pressure roller 212 is connected by a connecting plate. 209. The telescopic rod assembly 210 is connected to the bracket 206 and relies on the telescopic spring 213 sleeved on the outside of the telescopic rod assembly 210 to provide downward pressure. This ensures that there is sufficient friction between the pressed material belt and the conveyor roller 202 for stable conveying. Then, the material belt can be precisely conveyed to the stamping assembly 3 and stamped through the stamping machine body 301, upper die 302, base 303 and lower die 304. The stamped waste is discharged through the waste discharge plate 4. The entire working process, including the start and stop of the servo motor 205 and its speed, the action of the cylinder 207 and other electrical components, is coordinated and controlled by the controller 5 to ensure the reliability of operation.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
