Description

Technical Field

[0001] This utility model relates to the field of metal stamping feeding technology, specifically an automatic metal stamping feeding device. Background Technology

[0002] A stamping device is a piece of equipment used in metal processing. It is mainly used to apply external force to sheet metal, strip metal, tube metal, and profile metal through a press and a die, so as to cause the material to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size. The automatic feeding device for metal stamping is an automated device used in the metal stamping production process. Its main function is to automatically feed raw materials (such as metal sheets, coils, etc.) to the stamping die for processing without manual feeding, thereby improving production efficiency, reducing labor intensity and production costs, and ensuring the stability of the production process and the consistency of product quality.

[0003] The existing metal stamping equipment requires manual feeding, which has a low safety factor and is not conducive to production.

[0004] Therefore, we propose an automatic feeding device for metal stamping that can automatically feed metal materials, facilitate stamping, and improve the production safety factor. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic feeding device for metal stamping to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for metal stamping, comprising a stamping table, a support leg fixedly installed at the bottom of the stamping table, a metal workpiece body disposed on the top surface of the stamping table, an ejection mechanism disposed below the metal workpiece body, a pushing mechanism disposed above the ejection mechanism, a stamping mechanism disposed above the pushing mechanism, and a processing component disposed outside the metal workpiece body, the processing component including a feeding component disposed outside the metal workpiece body, and a positioning component disposed on the side of the feeding component.

[0007] Preferably, the feeding assembly includes a bracket fixedly installed on the outer wall of the stamping table, a motor fixedly installed on the top surface of the bracket, a threaded rod fixedly installed on the output end of the motor, a sleeve block sleeved on the outer wall of the threaded rod, a retaining frame fixedly installed on the outer wall of the sleeve block, a limit groove opened on the inner side of the retaining frame, a limit block slidably arranged inside the limit groove, a centering plate fixedly installed on the outer wall of the limit block, a spring fixedly installed on the outer wall of the centering plate, an extension plate fixedly installed on the outer wall of the retaining frame on the side away from the centering plate, a hopper provided above the stamping table, and a sliding groove opened on the top surface of the stamping table.

[0008] Preferably, the positioning component includes a slot formed on the top surface of the stamping table, a magnetic block is fixedly installed on the inner wall of the slot, a magnetic rod is engaged inside the slot, a baffle is fixedly installed at the end of the magnetic rod, a screw is threadedly connected inside the baffle, and a positioning plate is rotatably connected to the end of the screw.

[0009] Preferably, the outer wall of the centering plate is inclined, and there are two centering plates symmetrically distributed around the center line of the frame. Under the constraint of the inclined centering plates, they are smoothly snapped onto the outer wall of the hardware workpiece.

[0010] Preferably, the bottom surface of the extension plate is slidably disposed with the top surface of the stamping table, and the bottom surface of the card frame is slidably disposed with the top surface of the stamping table. Under these constraints, the rotating threaded rod can stably drive the card frame and the extension plate to move through the sleeve block.

[0011] Preferably, one end of the spring is fixedly installed on the side of the centering plate away from its inclined surface, and the other end of the spring away from the centering plate is fixedly installed on the inner side of the clamping frame. Under the elastic action of the spring, the centering plate is pushed, so that the centering plate clamps the metal workpiece body in the center, so as to move it precisely to the bottom of the stamping mechanism.

[0012] Preferably, the outer wall of the sleeve block is slidably disposed with the inside of the sliding groove, and the threaded rod is threadedly sleeved with the sleeve block. Under the sliding restriction between the sleeve block and the sliding groove, the rotating threaded rod drives the sleeve block to move.

[0013] Preferably, the magnetic block and the magnetic rod are magnetically attracted to each other, and the magnetic rod is fitted and engaged with the slot. Under the constraint of magnetic attraction, the baffle can be stably installed on the top surface of the stamping table.

[0014] Preferably, the outer wall of the positioning plate is slidably disposed with the top surface of the stamping table, and the outer wall of the positioning plate is rotatably connected to the end of the screw. Under its constraint, the rotating screw can push the positioning plate to finely adjust the distance between the positioning plate and the hardware workpiece body.

[0015] Preferably, there are two magnetic rods, symmetrically distributed around the center line of the bottom of the baffle. With the support and constraint of the two magnetic rods, the baffle is positioned and installed on the top surface of the stamping table.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This automatic feeding device for metal stamping consists of a feeding assembly. When stamping a metal workpiece, the workpiece body needs to be fed into the hopper. The workpiece body is placed inside the hopper and stacked. The motor is then started, and a threaded rod fixedly installed at its output end rotates. Due to the sliding groove between the outer wall of the sleeve block and the top surface of the stamping table, the rotating threaded rod drives the sleeve block on its outer wall to move. The sleeve block drives the clamping frame to move, causing the clamping frame to engage with the outer wall of the metal workpiece body being fed from the hopper. When the inclined surface of the centering plate contacts and presses against the outer wall of the metal workpiece body, the centering plate moves the limiting... The positioning block slides inside the limiting groove and compresses the spring. Under the elastic action of the spring, the centering plate clamps the outer wall of the metal workpiece. At this time, the moving clamping frame pushes the metal workpiece body unloaded from the hopper, causing the metal workpiece body to slide against the top surface of the stamping table and push the metal workpiece body directly below the stamping mechanism. Under the restriction of the two centering plates, the metal workpiece body is centered and clamped inside the clamping frame. When the metal workpiece body contacts the positioning component, the extension plate contacts the bottom of another metal workpiece body in the hopper, preventing the other metal workpiece body from contacting the top surface of the stamping table. At this time, the motor stops working. Under the constraint of the stamping mechanism, the conveyed metal workpiece body can be stamped. After stamping is completed, the ejection mechanism is activated to lift the stamped workpiece, and the pusher mechanism is activated to push out the scrap and workpiece. When the pusher plate in the pusher mechanism contacts the outer wall of the metal workpiece body, the motor is activated to drive the threaded rod to reverse, moving the sleeve block away from the support leg. The top surface of the extension plate slides into contact with the bottom of another metal workpiece body in the hopper. When the center plate inside the clamping frame is no longer in contact with the outer wall of the metal workpiece body, the pusher mechanism can push the stamped metal workpiece body. When the clamping frame and the extension plate slide into contact, the pusher mechanism can push out the stamped metal workpiece body. When the plate no longer supports the metal workpiece body in the hopper, the metal workpiece body falls under the action of gravity. The motor is restarted, causing the threaded rod to drive the clamping frame to fit the outer wall of the metal workpiece body and push the metal workpiece body directly below the stamping mechanism. This reciprocating motion realizes automatic feeding. This structure only requires the operator to add the metal workpiece body into the hopper, and does not require the operator to position the metal workpiece body directly below the stamping mechanism, thereby improving the overall safety factor of the stamping operation (the ejection mechanism, the pushing mechanism, and the stamping mechanism are existing public technologies, so their structures are not fully described in this case).

[0018] 2. This automatic feeding device for metal stamping consists of a positioning component. When a metal workpiece needs to be stamped, the feeding component pushes the workpiece directly below the stamping mechanism. Under the constraint of the positioning plate, the workpiece is prevented from shifting. When positioning workpieces of different sizes, the baffle is pulled to disengage the magnetic rod from the slot and engage it with another slot on the top surface of the stamping table. Under the magnetic attraction between the magnetic rod and the magnetic block, the baffle is stably installed on the top surface of the stamping table. At this time, the screw is rotated. Due to the sliding arrangement of the positioning plate and the top surface of the stamping table, the rotating screw drives the positioning plate to move, finely adjusting the distance between the baffle and the workpiece to accurately position the workpiece on the top surface of the stamping table.

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] Example 1: A preferred embodiment of the automatic feeding device for metal stamping provided by this utility model Figures 1 to 6 As shown: An automatic feeding device for metal stamping includes a stamping table 1;

[0028] The bottom of the stamping table 1 is fixedly equipped with support legs 2;

[0029] The top surface of the stamping table 1 is provided with a metal workpiece body 3;

[0030] An ejection mechanism 5 is provided below the hardware workpiece body 3;

[0031] A pushing mechanism 6 is provided above the ejection mechanism 5;

[0032] A stamping mechanism 7 is provided above the pushing mechanism 6;

[0033] The processing component 4 is located outside the hardware workpiece body 3. The processing component 4 includes a feeding component 41 located outside the hardware workpiece body 3. The feeding component 41 includes a bracket 411 fixedly installed on the outer wall of the stamping table 1. A motor 412 is fixedly installed on the top surface of the bracket 411. A threaded rod 413 is fixedly installed at the output end of the motor 412. A sleeve block 414 is sleeved on the outer wall of the threaded rod 413. A frame 415 is fixedly installed on the outer wall of the sleeve block 414. A limit groove 416 is opened on the inner side of the frame 415. A limit block 417 is slidably arranged inside the limit groove 416. A centering plate 418 is fixedly installed on the outer wall of the limit block 417. A spring 419 is fixedly installed on the outer wall of the centering plate 418. An extension plate 420 is fixedly installed on the outer wall of the frame 415 away from the centering plate 418. A hopper 421 is provided above the stamping table 1. A sliding groove 422 is opened on the top surface of the stamping table 1.

[0034] In this embodiment, when stamping the metal workpiece body 3, the metal workpiece body 3 needs to be loaded and stacked inside the unloading hopper 421. At this time, the motor 412 is started, and the threaded rod 413 fixedly installed at its output end rotates accordingly. Since the outer wall of the sleeve block 414 is slidably set with the sliding groove 422 opened on the top surface of the stamping table 1, under its restriction, the rotating threaded rod 413 drives the sleeve block 414 on its outer wall to move. The sleeve block 414 drives the clamping frame 415 to move, so that the clamping frame 415 is engaged with the outer wall of the metal workpiece body 3 unloaded from the unloading hopper 421. When the inclined surface of the centering plate 418 contacts and presses against the outer wall of the metal workpiece body 3, the centering plate 418 drives the limiting block 417 in the limiting groove 4. The internal sliding mechanism 16 compresses the spring 419. Under the elastic action of the spring 419, the centering plate 418 clamps the outer wall of the metal workpiece body 3. At this time, the moving clamping frame 415 pushes the metal workpiece body 3 unloaded from the hopper 421, causing the metal workpiece body 3 to slide against the top surface of the stamping table 1, pushing the metal workpiece body 3 directly below the stamping mechanism 7. Under the restriction of the two centering plates 418, the metal workpiece body 3 is centered and clamped inside the clamping frame 415. When the metal workpiece body 3 contacts the positioning component 43, the extension plate 420 contacts the bottom of another metal workpiece body 3 in the hopper 421, preventing the other metal workpiece body 3 from contacting the top surface of the stamping table 1. At this time, the motor 412 no longer... Under the constraint of the stamping mechanism 7, the conveyed metal workpiece body 3 can be stamped. After stamping is completed, the ejection mechanism 5 is activated to lift the stamped workpiece, and the pusher mechanism 6 is activated to push out the scrap and workpiece. When the pusher plate in the pusher mechanism 6 contacts the outer wall of the metal workpiece body 3, the motor 412 is activated to drive the threaded rod 413 to reverse, moving the sleeve block 414 away from the support leg 2. The top surface of the extension plate 420 slides into contact with the bottom of another metal workpiece body 3 in the hopper 421. When the centering plate 418 inside the clamping frame 415 is no longer in contact with the outer wall of the metal workpiece body 3, the pusher mechanism 6 can push the stamped metal workpiece body 3. When the extension plate 420 no longer supports the metal workpiece body 3 in the hopper 421, the metal workpiece body 3 falls under the action of gravity. The motor 412 is restarted, and the threaded rod 413 drives the clamping frame 415 to fit the outer wall of the metal workpiece body 3, pushing the metal workpiece body 3 directly below the stamping mechanism 7. This reciprocating action realizes automatic feeding. This structure only requires the operator to put the metal workpiece body 3 into the hopper 421. It does not require the operator to position the metal workpiece body 3 directly below the stamping mechanism 7, thereby improving the overall safety factor of the stamping operation (the ejection mechanism 5, the pushing mechanism 6 and the stamping mechanism 7 are existing public technologies, so their structures are not fully described in this case).

[0035] Among them, the outer wall of the center plate 418 is set with an sloping surface. There are two center plates 418, which are symmetrically distributed around the center line of the frame 415. Under the restriction of the sloping center plates 418, they are smoothly snapped onto the outer wall of the hardware workpiece body 3.

[0036] The bottom surface of the extension plate 420 is slidably disposed with the top surface of the stamping table 1, and the bottom surface of the frame 415 is slidably disposed with the top surface of the stamping table 1. Under their restriction, the rotating threaded rod 413 can stably drive the frame 415 and the extension plate 420 to move through the sleeve block 414.

[0037] One end of the spring 419 is fixedly installed on the side of the centering plate 418 away from its inclined surface, and the other end of the spring 419 away from the centering plate 418 is fixedly installed on the inner side of the frame 415. Under the elastic action of the spring 419, the centering plate 418 is pushed, so that the centering plate 418 clamps the metal workpiece body 3 in the center, so as to accurately move it to the bottom of the stamping mechanism 7.

[0038] The outer wall of the sleeve 414 is slidably disposed with the inside of the slide groove 422, and the threaded rod 413 is threadedly sleeved with the sleeve 414. Under the sliding restriction between the sleeve 414 and the slide groove 422, the rotating threaded rod 413 drives the sleeve 414 to move.

[0039] Example 2: Based on Example 1, a preferred embodiment of the automatic feeding device for metal stamping provided by this utility model is as follows: Figures 1 to 6 As shown: The positioning component 43 includes a slot 431 formed on the top surface of the stamping table 1. A magnetic block 432 is fixedly installed on the inner wall of the slot 431. A magnetic rod 433 is engaged inside the slot 431. A baffle 434 is fixedly installed at the end of the magnetic rod 433. A screw 435 is threadedly connected inside the baffle 434. A positioning plate 436 is rotatably connected to the end of the screw 435.

[0040] In this embodiment, when it is necessary to stamp the metal workpiece body 3, the metal workpiece body 3 is fed by the feeding component 41 and pushed to the bottom of the stamping mechanism 7. Under the restriction of the positioning plate 436, the metal workpiece body 3 is prevented from moving out of place. When positioning the metal workpiece body 3 of different sizes, the baffle 434 is pulled so that the magnetic rod 433 is no longer engaged with the slot 431, and the magnetic rod 433 is engaged with another slot 431 opened on the top surface of the stamping table 1. Under the restriction of the magnetic attraction between the magnetic rod 433 and the magnetic block 432, the baffle 434 is stably installed on the top surface of the stamping table 1. At this time, the screw 435 is rotated. Since the positioning plate 436 is slidably set with the top surface of the stamping table 1, under its restriction, the rotating screw 435 drives the positioning plate 436 to move, and the distance between the baffle 434 and the metal workpiece body 3 is finely adjusted so as to accurately position the metal workpiece body 3 on the top surface of the stamping table 1.

[0041] Among them, the magnetic block 432 and the magnetic rod 433 are magnetically attracted to each other, and the magnetic rod 433 is adapted to be engaged with the slot 431. Under the restriction of magnetic attraction, the baffle 434 can be stably installed on the top surface of the stamping table 1.

[0042] The outer wall of the positioning plate 436 is slidably disposed with the top surface of the stamping table 1, and the outer wall of the positioning plate 436 is rotatably connected with the end of the screw 435. Under its constraint, the rotating screw 435 can push the positioning plate 436 to finely adjust the distance between the positioning plate 436 and the metal workpiece body 3.

[0043] There are two magnetic rods 433, which are symmetrically distributed around the bottom center line of the baffle 434. With the support and constraint of the two magnetic rods 433, the baffle 434 is positioned and installed on the top surface of the stamping table 1.

[0044] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
