Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an automatic stamping device for multi-material belt feeding. Background Technology

[0002] The multi-strip feeding automatic stamping device is a high-efficiency production equipment that integrates mechanical structure, automated control and metal processing technology. It can simultaneously and accurately transport different types of strips to the stamping station through multiple independent feeding mechanisms (including strip support components, drive rollers or clamping units and guide positioning components), and complete the processing in conjunction with the integrated stamping execution mechanism composed of stamping dies, power output devices and frame.

[0003] Existing multi-material strip feeding automatic stamping devices use hook-type feeding devices, which rely on the pulling hook to pull the process overlap to achieve automatic feeding. Its structure is simple and low cost. However, this conveying method cannot be used for materials without overlap (such as precision parts and irregularly shaped parts), and the overlap strength is insufficient, which will cause problems such as overlap tearing and material deformation. Existing technology uses a clamping feeding device, which uses the reciprocating motion of the slider mechanism to feed materials. However, the clamping feeding needs to complete the cycle of "clamping-feeding-releasing-resetting", which has an unavoidable empty stroke (no material is conveyed during the reset phase). The inertia of the slider will cause the action response to be delayed, resulting in unstable feeding or positioning deviation. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an automatic stamping device for multi-material belt feeding, which aims to improve the existing technology where clamping feeding requires completing a cycle of "clamping-feeding-releasing-resetting", which inevitably results in empty strokes (no material is conveyed during the reset phase). The inertia of the slider will cause the action response to be delayed, resulting in unstable feeding or positioning deviation.

A rotating shaft is fixedly connected to the middle of the worm wheel. A double gear is fixedly connected to the other end of the outer wall of the rotating shaft. The left and right sides of the outer wall of the rotating shaft are rotatably connected to the inner wall of the support frame. A double rack is installed on the front side of the outer wall of the double gear, and the front side of the outer wall of the double gear meshes with the rear side of the outer wall of the double rack.

The front side of the outer wall of the rotating frame is fixedly connected to the rear side of the outer wall of the stamping plate.

[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the first drive motor is turned on, which drives the active roller to rotate inside the support frame at both ends. The rotating adjustment turntable causes the worm gear to rotate, which in turn drives the centrally welded shaft to rotate inside the support frame. The double gear at the other end of the shaft rotates accordingly, which in turn drives the double rack to slide inside the support frame. The movement of the double rack drives the driven roller welded at the bottom to slide inside the support frame. The distance between the roller and the active roller is adjusted to accommodate different materials. The material is conveyed by the friction between the two pressure rollers and the material, which achieves zero-empty-stroke conveying of the material while ensuring the stability and accurate positioning of the material conveying.

[0022] 2. In this utility model, the second drive motor is started, and its output end drives the reciprocating plate to rotate, causing the rotating frame on the top of the reciprocating plate to move accordingly. Due to the restriction of the upper part of the limiting frame, the front end of the rotating frame always maintains a linear motion. Since the front side of the rotating frame is welded to the stamping plate, it drives the stamping plate to move on the slide rod through the slide groove. Through the reciprocating motion of the stamping plate, the stamped workpiece can be quickly collected, improving the stamping efficiency of the device on materials. Attached Figure Description

[0033] 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.

[0034] Reference Figure 4 , Figure 5 and Figure 6This utility model provides an embodiment of an automatic stamping device with multi-material belt feeding, comprising a machine body 1. Multiple conveying mechanisms 2 are installed at the outer front end of the machine body 1, each conveying mechanism 2 being used to convey materials. Multiple collecting mechanisms 3 are installed at the rear end of the machine body 1, each collecting mechanism 3 being used to remove workpieces. Each of the multiple conveying mechanisms 2 includes a drive roller 201, which is installed at the outer front end of the machine body 1. A first drive motor 202 is fixedly connected to the outer wall of each drive roller 201. The model of the first drive motor 202 is... The 130ST-M15015 receives external commands through a driver, while the encoder acquires the actual rotor state. If there is a deviation between the actual state and the command, the driver adjusts the stator current and changes the rotational magnetic field speed or direction until the deviation is eliminated, achieving high-precision control. Support frames 204 are installed on both the left and right ends of the outer wall of the drive roller 201. The bottom ends of multiple support frames 204 are rotatably connected to the outer wall of the drive roller 201. A driven roller 203 is installed on the top outer side of the drive roller 201. The driven roller 203 has support frames 204 on both the left and right ends of its outer wall. The support frame 204 is internally slidably connected to the support frame 204. An adjustment assembly 205 is installed in the middle of the support frame 204. The adjustment assembly 205 includes an adjustment turntable 2051, which is installed in the middle of the support frame 204. A worm gear 2052 is fixedly connected to the rear side of the outer wall of the adjustment turntable 2051. The outer wall of the worm gear 2052 is rotatably connected to the front end of the support frame 204. A worm wheel 2053 is installed at the bottom of the outer wall of the worm gear 2052, and the bottom of the outer wall of the worm gear 2052 meshes with the top of the outer wall of the worm wheel 2053. A rotating shaft 2054 is fixedly connected to the middle of 2053. A double gear 2055 is fixedly connected to the other end of the outer wall of the rotating shaft 2054. The left and right sides of the outer wall of the rotating shaft 2054 are rotatably connected to the inner wall of the support frame 204. A double rack 2056 is installed on the front side of the outer wall of the double gear 2055. The front side of the outer wall of the double gear 2055 is meshed with the rear side of the outer wall of the double rack 2056. The outer wall of the double rack 2056 is slidably connected to the inside of the support frame 204. The bottom of the outer wall of the double rack 2056 is fixedly connected to the outer wall of the driven roller 203.

[0035] Specifically, turning on the first drive motor 202 causes the drive roller 201 to rotate inside the support frames 204 at both ends. Rotating the adjusting turntable 2051 allows the worm gear 2052 on its outer wall to mesh with the worm wheel 2053 under the support of the internal space at the front end of the support frame 204. This causes the worm wheel 2053 to drive the rotating shaft 2054 in the middle to rotate inside the support frame 204. The double gear 2055 at the other end of the rotating shaft 2054 rotates accordingly. Through the meshing action of the double gear 2055 and the double rack 2056, the double rack 2056 can be driven to rotate within the support frame 204. The rack 2056 slides inside the support frame 204. The short shaft inside the rack 2056 is fixed inside the support frame 204, providing stable support for the movement of the rack 2056 and preventing deviation during sliding. The movement of the rack 2056 can drive the driven roller 203 at its bottom to slide inside the support frame 204, thereby adjusting the distance between it and the driving roller 201 to adapt to the size of different materials. It conveys the material through the friction between the two pressure rollers and the material, so that the material is subjected to uniform force, realizing the material conveying without empty stroke while ensuring the stability and accurate positioning of the material conveying.

[0036] Reference Figure 3 , Figure 7 and Figure 8 Each of the multiple receiving mechanisms 3 includes a stamping plate 301, which is installed at the rear end of the machine body 1. Multiple sliding grooves 302 are formed at the bottom of each stamping plate 301, and sliding rods 303 are slidably connected inside each groove 302. The bottom of the outer wall of each sliding rod 303 is fixedly connected to the inner wall of the machine body 1. A reciprocating assembly 304 is installed on the rear side of the outer wall of the stamping plate 301. The reciprocating assembly 304 includes a second drive motor 3041, model 130ST-M15015, which receives external commands through a driver and simultaneously acquires the actual rotor state through an encoder. If there is a deviation between the actual state and the command, the driver adjusts the stator current and changes the speed or direction of the rotating magnetic field until the deviation is eliminated, thus achieving high-precision control. The second drive motor 3041 is installed on the rear side of the outer wall of the machine body 1. The output end of the second drive motor 3041 is rotatably connected to the reciprocating disk 3042. The top of the outer wall of the reciprocating disk 3042 is fixedly connected to the rotating frame 3043. The front end of the outer wall of the rotating frame 3043 is installed with a limit frame 3044. The upper middle inner wall of the limit frame 3044 is slidably connected to the outer wall of the rotating frame 3043. The front side of the outer wall of the rotating frame 3043 is fixedly connected to the rear side of the outer wall of the stamping plate 301.

[0037] Specifically, starting the second drive motor 3041 causes the reciprocating disc 3042 to rotate, which in turn causes the rotating frame 3043 on top of the reciprocating disc 3042 to move. The upper part of the limit frame 3044 restricts the movement of the front end of the rotating frame 3043, ensuring that it always moves in a straight line. Since the front side of the rotating frame 3043 is connected to the stamping plate 301, it can drive the stamping plate 301 to move on the slide rod 303 through the slide groove 302. The slide rod 303 provides guidance and support for the movement of the stamping plate 301. Through the reciprocating motion of the stamping plate 301, the stamped workpiece can be quickly collected, improving the stamping efficiency of the device.

[0038] Reference Figure 1 , Figure 2 and Figure 3 Multiple conveyor belts 7 are installed on the front side of the outer wall of the machine body 1. Multiple conveying mechanisms 2 are installed on the top of the conveyor belts 7. Multiple stamping machines 4 are installed on the top of the machine body 1. Stamping dies 5 are installed on the output end of the multiple stamping machines 4. A heat sink 6 is fixedly connected to the rear side of the bottom of the machine body 1. Multiple rectangular slots are opened on the heat sink 6. A bracket 8 is fixedly connected to the bottom of the outer wall of the first drive motor 202. The outer wall of the bracket 8 is fixedly connected to the outer wall of the conveyor belt 7.

[0039] Specifically, the front of the machine body 1 is equipped with multiple conveyor belts 7, which can continuously transport the same or different materials to be stamped to the processing area. Two conveying mechanisms 2 are respectively installed on the conveyor belts 7 to accurately transfer the materials on the conveyor belts 7 to the stamping position. The top of the machine body 1 has multiple stamping machines 4, which provide power for the stamping operation. The output end of each of the multiple stamping machines 4 has a stamping die 5. Different stamping dies 5 can be used according to processing requirements, and the power of the stamping machines 4 can be used to stamp the materials. The bottom rear of the machine body 1 has a heat dissipation plate 6, which can dissipate the heat generated inside the machine body 1 to avoid the temperature from being too high and affecting the performance of the equipment. The bottom of the outer wall of the first drive motor 202 has a bracket 8. The bracket 8 is welded to the outside of the conveyor belts 7 to provide stable support for the first drive motor 202 and ensure its stability during operation. All components work together to ensure the orderly and efficient completion of the stamping operation.

[0040] Working principle: When the first drive motor 202 is turned on, the active roller 201 can rotate inside the support frames 204 at both ends. Rotating the adjusting turntable 2051, the worm gear 2052 welded to its outer wall can mesh with the worm wheel 2053 under the support of the internal space at the front end of the support frame 204. This causes the worm wheel 2053 to drive the rotating shaft 2054 welded in the middle to rotate inside the support frame 204. The double gear 2055 at the other end of the rotating shaft 2054 rotates accordingly. Through the meshing action of the double gear 2055 and the double rack 2056, the double gear can be driven... The rack 2056 slides inside the support frame 204. The short shaft inside the rack 2056 is fixed inside the support frame 204, providing stable support for the movement of the rack 2056. The movement of the rack 2056 can drive the driven roller 203 welded to its bottom to slide inside the support frame 204, thereby adjusting the distance with the driving roller 201 to adapt to different materials. It conveys the material through the friction between the two pressure rollers and the material, which can make the material evenly stressed and realize the material conveying without empty stroke while ensuring the stability and accurate positioning of the material conveying.

[0041] The second drive motor 3041 is started, and its output end can drive the reciprocating plate 3042 to rotate, thereby causing the rotating frame 3043 on the top of the reciprocating plate 3042 to move accordingly. Through the restriction of the upper part of the limit frame 3044, the front end of the rotating frame 3043 always maintains a linear motion. Since the front side of the rotating frame 3043 is welded to the stamping plate 301, it can drive the stamping plate 301 to move on the slide rod 303 through the slide groove 302. Through the reciprocating motion of the stamping plate 301, the stamped workpiece can be quickly collected, improving the stamping efficiency of the device.

[0042] 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.
