Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding devices, and particularly relates to an automatic feeding device for stamping die processing. Background Technique

[0002] A stamping die is a special process equipment used in cold stamping processing for processing metal materials into parts or semi-finished products. Generally, it consists of an upper die and a lower die. By placing a metal sheet into the lower die, the upper die extrudes the metal sheet under the action of a hydraulic cylinder, so that the metal sheet forms the required shape. An automatic feeding device is an important part used in stamping die processing. It can improve production efficiency, reduce costs and reduce human resources, avoid workers feeding materials in person, and increase safety. Currently, it is widely used.

[0003] For the existing automatic feeding device, generally, the metal sheet is sucked and moved in position for feeding. Most of the fixing methods for the metal sheet are magnetic attraction or air pressure suction, etc., to fix the metal sheet for conveying in the air for feeding. For example, a stamping die for automatic feeding with the publication number of CN220444889U adopts the magnetic attraction method. However, only relying on this magnetic attraction method to fix the metal sheet without setting a limiting mechanism may cause the position of the metal sheet to shift or rotate.

[0004] When stamping a non-circular metal sheet, since the length and width of the metal sheet are different, the metal sheet generally needs a corresponding angle when placed in the die. When the position of the metal sheet shifts or the angle changes, it is easy to cause the metal sheet to not be able to be placed in the die, which is not convenient for use. To solve this technical problem, the utility model proposes an automatic feeding device for stamping die processing. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide an automatic feeding device for stamping die processing, which can effectively solve the problems mentioned in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An automatic feeding device for stamping die processing, including a base, above which a stamping mechanism is arranged, and a power mechanism is also arranged above the base. One end of the power mechanism is provided with a fixed box, and a fixing plate is installed on the lower surface of the fixed box. A positioning plate is slidably connected to the outer surfaces of the fixing plate and the fixed box. A rebound mechanism is arranged outside the positioning plate. An electromagnet and a first telescopic rod are installed inside the fixed box. The bottom end of the electromagnet is flush with the fixing plate, and the extending end of the first telescopic rod is slidably connected to the fixing plate. A conveyor belt is installed on one side of the base, and metal sheets are arranged on the conveyor belt. A die is installed on the upper surface of the base.

[0008] Preferably, the stamping mechanism includes a support plate, the lower surface of the support plate is fixedly connected to the base, and a second telescopic rod is installed at the upper end of the support plate. A stamping plate is installed at the extending end of the second telescopic rod.

[0009] Preferably, the power mechanism includes a motor, the lower surface of the motor is installed on the base, and the output end of the motor is connected to a connecting plate.

[0010] Preferably, a third telescopic rod is installed at the end of the connecting plate away from the motor, and the extending end of the third telescopic rod is fixedly connected to the fixed box.

[0011] Preferably, the rebound mechanism includes a first fixing block, one side surface of the first fixing block is fixedly connected to the positioning plate, and a sliding rod is fixedly connected to the upper surface of the first fixing block.

[0012] Preferably, a second fixing block is slidably connected to the outer surface of the sliding rod, and one side surface of the second fixing block is fixedly connected to the fixed box.

[0013] Preferably, a spring is sleeved on the outer surface of the sliding rod. One end of the spring is fixedly connected to the first fixing block, and the other end of the spring is fixedly connected to the second fixing block.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, by setting components such as the positioning plate and the die, the inner wall of the positioning plate guides the metal sheet, making the metal sheet move closer to the middle, so that the metal sheet is vertically flush with the fixing plate, achieving the effect of positioning the metal sheet and preventing the metal sheet from shifting when being sucked. The inner wall of the positioning plate fits with the outer surface of the die, enabling the metal sheet to enter the die. The inner wall of the die limits the metal sheet to prevent the metal sheet from shifting or rotating when falling, achieving the effect of preventing the metal sheet from shifting when being placed, thus solving the problem that when the position or angle of the metal sheet changes, it is easy to cause the metal sheet to be unable to be placed into the die, which is not convenient for use.

[0016] In the present utility model, by providing components such as a spring-back mechanism, a spring gives a downward elastic force to the first fixing block, causing the first fixing block to move away from the second fixing block, enabling the positioning plate to move downward. By providing two electromagnets, rotation of the metal sheet is prevented. The shape of the stamping plate is adapted to the interior of the mold. The second telescopic rod drives the stamping plate into the interior of the mold, and the metal sheet inside the mold can be stamped. Description of the Drawings

Detailed Embodiments

[0023] To make the technical means, creative features, achieved purposes, and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1-5 shown, an automatic loading device for stamping die processing includes a base 1. Above the base 1, there is a stamping mechanism 2. The stamping mechanism 2 includes a support plate 201. The lower surface of the support plate 201 is fixedly connected to the base 1. The upper end of the support plate 201 is equipped with a second telescopic rod 202, and the extending end of the second telescopic rod 202 is equipped with a stamping plate 203.

[0025] Above the base 1, a power mechanism 3 is also provided. One end of the power mechanism 3 is provided with a fixed box 4. The power mechanism 3 includes a motor 301. The lower surface of the motor 301 is mounted on the base 1. The output end of the motor 301 is connected to a connecting plate 302. The connecting plate 302 can be driven to rotate by the motor 301. One end of the connecting plate 302 away from the motor 301 is mounted with a third telescopic rod 303. The extended end of the third telescopic rod 303 is fixedly connected to the fixed box 4. The fixed box 4 can be driven to move up or down by the third telescopic rod 303.

[0026] A fixed plate 5 is mounted on the lower surface of the fixed box 4. A positioning plate 6 is slidably connected to the outer surfaces of the fixed plate 5 and the fixed box 4. A rebound mechanism 7 is arranged outside the positioning plate 6. The rebound mechanism 7 includes a first fixed block 701. One side surface of the first fixed block 701 is fixedly connected to the positioning plate 6. A sliding rod 702 is fixedly connected to the upper surface of the first fixed block 701. A second fixed block 703 is slidably connected to the outer surface of the sliding rod 702. One side surface of the second fixed block 703 is fixedly connected to the fixed box 4. A spring 704 is sleeved on the outer surface of the sliding rod 702. One end of the spring 704 is fixedly connected to the first fixed block 701. The other end of the spring 704 is fixedly connected to the second fixed block 703. A downward elastic force is given to the first fixed block 701 by the spring 704, so that the first fixed block 701 moves away from the second fixed block 703, and the positioning plate 6 can move downward.

[0027] An electromagnet 8 and a first telescopic rod 9 are installed inside the fixed box 4. The bottom end of the electromagnet 8 is flush with the fixed plate 5. The extended end of the first telescopic rod 9 is slidably connected to the fixed plate 5. A conveyor belt 10 is installed on one side of the base 1. Metal sheets 11 are arranged on the conveyor belt 10. A mold 12 is mounted on the upper surface of the base 1. The shape of the stamping plate 203 is adapted to the inside of the mold 12. The stamping plate 203 can be driven by the second telescopic rod 202 to enter the inside of the mold 12, and the metal sheet 11 inside the mold 12 can be stamped. The shape of the positioning plate 6 is rectangular, and openings penetrating up and down are provided in the middle. The inner wall has a certain slope. The upper part of the opening is the same as the shape of the fixed plate 5 and is the same size as the fixed plate 5, and can slide closely along the outer surface of the fixed plate 5. The lower part of the opening is larger than the upper part, and the overall shape is a frustum of a pyramid. The outer surface of the mold 12 has a certain slope, which is adapted to the slope of the inner wall of the positioning plate 6. The positioning plate 6 can be sleeved on the outside of the mold 12. The lower surface of the fixed plate 5 is the same size and shape as the metal sheet 11. At the same time, the shape and size of the inner wall of the mold 12 are also the same as those of the metal sheet 11.

[0028] It should be noted that during the actual use of the device, the conveyor belt 10 conveys the metal sheet 11, causing the metal sheet 11 to move to the lower part of the positioning plate 6. Then the conveyor belt 10 stops conveying, and the third telescopic rod 303 extends to drive the fixed box 4 to move downward. The fixed box 4 drives the fixed plate 5 and the positioning plate 6 to move downward. The positioning plate 6 sleeves the metal sheet 11 inside. After the lower surface of the positioning plate 6 contacts the conveyor belt 10, under the influence of the reaction force of the conveyor belt 10, the position of the positioning plate 6 remains unchanged, and the fixed plate 5 continues to move downward. At the same time, the second fixed block 703 compresses the spring 704. After the lower surface of the fixed plate 5 contacts the metal sheet 11, the electromagnet 8 is powered on, thereby sucking the metal sheet 11. Then it slowly rises. The electromagnet 8 drives the metal sheet 11 to move upward. At the same time, under the action of the spring 704, the positioning plate 6 moves downward relative to the metal sheet 11. The inner wall of the positioning plate 6 guides the metal sheet 11 to move closer to the middle, so that the metal sheet 11 is vertically flush with the fixed plate 5, achieving the effect of positioning the metal sheet 11 and preventing the metal sheet 11 from shifting when being sucked. By setting two electromagnets 8, the metal sheet 11 is fixed at two positions to prevent the metal sheet 11 from rotating, thereby increasing the stability of the metal sheet 11.

[0029] The motor 301 drives the connecting plate 302 to rotate 180 degrees, causing the metal sheet 11 to rotate above the mold 12. The third telescopic rod 303 extends to drive the positioning plate 6 to move downward close to the mold 12, so that the positioning plate 6 sleeves onto the mold 12. The inner wall of the positioning plate 6 fits with the outer surface of the mold 12, enabling the metal sheet 11 to enter the interior of the mold 12. The electromagnet 8 is powered off, causing the metal sheet 11 to move downward. The inner wall of the mold 12 limits the metal sheet 11 to prevent the metal sheet 11 from shifting or rotating during the fall, achieving the effect of preventing the metal sheet 11 from shifting during the lowering process. At the same time, the first telescopic rod 9 pushes the metal sheet 11 downward to prevent the metal sheet 11 from having too much friction with the inner wall of the mold 12 and being unable to reach the bottom.
