Description

Technical Field

[0001] This invention relates to the field of metal stamping technology, and in particular to a continuous stamping production process for metal parts. Background Technology

[0002] Hardware refers to tools made of metals such as gold, silver, copper, iron, and tin through processing and casting. They are used to fix things, process things, and decorate. In the production and processing of hardware, special stamping equipment is required to process the hardware. Hardware stamping is divided into multiple steps, such as punching, stamping and forming, and blanking.

[0003] Existing stamping equipment has structures such as a die base, a stamping head, and a drive device. The metal parts to be stamped are placed on the die base, and the corresponding die base and stamping head can be used to perform operations such as punching, stamping and blanking on the metal parts.

[0004] In the current stamping equipment, during the punching process of hardware parts, the scrap material that falls off the punch is guided into a special scrap collection box by a guide plate. The guide plate is usually set at an angle directly below the punching hole of the die base. The scrap material will fall onto the guide plate and may accumulate on the guide plate, making it impossible for the scrap material to slide down smoothly. Due to the accumulation of scrap material, the current stamping equipment cannot make the scrap material slide down the guide plate smoothly. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the fact that the current stamping equipment in the prior art cannot allow the waste to slide smoothly down the guide plate due to the accumulation of waste.

[0006] To solve the above-mentioned technical problems, the present invention provides a continuous stamping production process for hardware parts, comprising the following steps:

[0007] S1: Select a standard rectangular hardware component and stack it neatly on one side of the stamping equipment so that the hardware component is in the pick-up position of the suction cup. When the suction cup is not working, it is in the middle standby position.

[0008] S2: The suction cup can be driven to the picking position by the driving device. The suction cup can pick up a single hardware part. Then, the suction cup is driven by the driving device to place the hardware part in the punching position. After the placement is completed, the suction cup returns to the middle standby position.

[0009] S3: Start the punching equipment. The punching equipment can punch holes in the hardware parts. The waste material that falls off during punching is collected in the waste box.

[0010] S4: After punching is completed, the punched metal parts are transported to the next processing station, namely the stamping station, by the drive device to drive the suction cup.

[0011] S5: Starting the stamping forming equipment can stamp the hardware parts located at the stamping position, and then use the drive equipment to drive the suction cup to transport the stamped hardware parts to the next processing position, namely the blanking position.

[0012] S6: Starting the punching equipment can trim the edges of the hardware parts located at the punching position, removing excess waste. The drive equipment then drives the suction cup to remove the punched hardware parts, thus completing the continuous punching of the hardware parts.

[0013] In one embodiment of the present invention, the stamping equipment in S1 includes a base plate, a horizontal drive structure fixedly connected to the top of the base plate, a connecting column slidably connected to the horizontal drive structure, a vacuum suction cup mounted on the connecting column, the vacuum suction cup being used to pick up hardware parts, the horizontal drive structure being used to drive the vacuum suction cup to move in the horizontal direction, a support column fixedly connected to the top of the base plate, and a mold base fixedly connected to the top of the four support columns, the three mold bases being, from left to right, a punching mold, a stamping forming mold, and a blanking mold, the three mold bases having stamping grooves, the leftmost mold base having a stamping hole, a vertical drive structure mounted on the horizontal drive structure, and a stamping head mounted on the vertical drive structure, the three stamping heads being respectively adapted to the mold bases below.

[0014] In one embodiment of the present invention, two first fixing plates are fixedly connected to the top of the base plate, and a feeding plate is rotatably connected between the two first fixing plates by a pin. A fence is provided on the top of the feeding plate, and the feeding plate is inclined.

[0015] In one embodiment of the present invention, a connecting rod is fixedly connected to one of the connecting columns, a first semicircular block is fixedly connected to the bottom end of the connecting rod, a connecting plate is fixedly connected to one end of the feed plate, a second semicircular block is fixedly connected to the top of the connecting plate, the second semicircular block is located on the trajectory of the first semicircular block moving with the vacuum suction cup, and two first springs are fixedly connected to the top of the bottom plate, the top of the first springs contacting the bottom of the feed plate.

[0016] In one embodiment of the present invention, an impact block is fixedly connected to the top of the connecting plate, and a rubber pad is fixedly connected to the bottom of the feeding plate, with the rubber pad located above the impact block.

[0017] In one embodiment of the present invention, a draining rod is fixedly connected to the feeding plate, the top end of the draining rod is set to be arc-shaped, the draining rod is located below the punching hole, and the vertical surface of the draining rod is close to the inner wall of the punching hole.

[0018] In one embodiment of the present invention, a second fixing plate is fixedly connected to the unblocking rod, and a unblocking plate is rotatably connected to the second fixing plate via a pin. A second spring is fixedly connected between the unblocking plate and the unblocking rod.

[0019] In one embodiment of the present invention, a third fixing plate is fixedly connected to the side wall of the feeding plate, a guide rod is slidably inserted into the third fixing plate, a movable plate is fixedly connected to one end of the guide rod, a third spring is fixedly connected between the movable plate and the third fixing plate, the third spring is sleeved on the outside of the guide rod, a rack is fixedly connected to the movable plate, a plurality of rotating rollers are rotatably connected to the feeding plate via bearings, a gear is fixedly connected to one end of the rotating rollers, the rack meshes with the plurality of gears, a fixing rod is fixedly connected to one end of the rack, an arc-shaped rod is fixedly connected to one end of the fixing rod, a vertical plate is fixedly connected to the top of the bottom plate, a fixing column is fixedly connected to the vertical plate, and the fixing column is located on the trajectory of the arc-shaped rod rotating around the pin shaft.

[0020] In one embodiment of the present invention, a plurality of rotating teeth are fixedly connected to the surface of the rotating roller, the tip of the top rotating tooth faces the feeding point of the feeding plate, the feeding plate is provided with sponge blocks located on both sides of the rotating roller, the rotating teeth are provided with slots, a fourth spring is fixedly connected in the slots, a fourth fixing plate is fixedly connected to the top of the fourth spring, and a roller is rotatably connected to the fourth fixing plate through a bearing.

[0021] In one embodiment of the present invention, a circular hole is provided on the third fixing plate, and the guide rod slides through the circular hole.

[0022] The technical solution of the present invention has the following advantages compared with the prior art:

[0023] This invention, by setting up a blanking plate and a first spring, allows scrap material to fall from the stamping hole onto the blanking plate during the stamping process. During the movement of the vacuum suction cup, the connecting column drives the first semicircular block to move. The first semicircular block contacts the second semicircular block and presses it downwards. The second semicircular block drives the connecting plate and the blanking plate to rotate around the pin, compressing the first spring. When the vacuum suction cup leaves, the first and second semicircular blocks no longer contact each other. Under the action of the first spring, the blanking plate suddenly rotates upwards and vibrates back and forth. The blanking plate drives the impact block to impact the mold base, generating vibration. This vibration is transmitted to the blanking plate, allowing the accumulated scrap material to slide off, thus solving the problem in current stamping equipment where scrap accumulation prevents the scrap material from smoothly sliding off the guide plate.

[0024] This invention utilizes a rotating roller. During the reciprocating vibration of the feeding plate, the feeding plate drives the arc-shaped rod to move. The arc-shaped rod contacts the fixed column, which in turn compresses the arc-shaped rod, causing it to move back and forth. The arc-shaped rod drives the fixed rod and rack to move back and forth. The rack drives multiple gears to rotate reciprocally, which in turn drives the rotating roller to rotate reciprocally. When the rotating roller rotates counterclockwise, the rotating teeth on the roller push the waste material downwards along the feeding plate. When the rotating roller rotates clockwise, the roller contacts and rotates with the waste material, thus preventing the excessive friction between the rotating teeth and the waste material from pushing the waste material upwards.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0036] Reference Figures 1-8 As shown, a continuous stamping production process for hardware parts includes the following steps:

[0037] S1: Select a standard rectangular hardware component and stack it neatly on one side of the stamping equipment so that the hardware component is in the pick-up position of the suction cup. When the suction cup is not working, it is in the middle standby position.

[0038] S2: The suction cup can be driven to the picking position by the driving device. The suction cup can pick up a single hardware part. Then, the suction cup is driven by the driving device to place the hardware part in the punching position. After the placement is completed, the suction cup returns to the middle standby position.

[0039] S3: Start the punching equipment. The punching equipment can punch holes in the hardware parts. The waste material that falls off during punching is collected in the waste box.

[0040] S4: After punching is completed, the punched metal parts are transported to the next processing station, namely the stamping station, by the drive device to drive the suction cup.

[0041] S5: Starting the stamping forming equipment can stamp the hardware parts located at the stamping position, and then use the drive equipment to drive the suction cup to transport the stamped hardware parts to the next processing position, namely the blanking position.

[0042] S6: Starting the punching equipment can trim the edges of the hardware parts located at the punching position, removing excess waste. The drive equipment then drives the suction cup to remove the punched hardware parts, thus completing the continuous punching of the hardware parts.

[0043] Furthermore, such as Figure 1 As shown, the stamping equipment in S1 includes a base plate 1. A horizontal drive structure 2 is fixedly connected to the top of the base plate 1. A connecting column 3 is slidably connected to the horizontal drive structure 2. A vacuum suction cup 4 is installed on the connecting column 3. The vacuum suction cup 4 is used to pick up hardware parts. The horizontal drive structure 2 is used to drive the vacuum suction cup 4 to move in the horizontal direction. A support column 5 is fixedly connected to the top of the base plate 1. A mold base 6 is fixedly connected to the top of the four support columns 5. The three mold bases 6, from left to right, are a punching mold, a stamping forming mold, and a blanking mold. The three mold bases 6 have stamping grooves 7. The leftmost mold base 6 has a stamping hole 8. A vertical drive structure 9 is installed on the horizontal drive structure 2. A stamping head 10 is installed on the vertical drive structure 9. The three stamping heads 10 are respectively adapted to the mold bases 6 below. The hardware parts to be processed are neatly stacked on the left side of the equipment, so that the hardware parts are in the picking position. The horizontal drive structure 2 is activated, which drives the vacuum suction cup 4 to move, so that the vacuum suction cup 4 reaches the picking position and picks up the hardware parts. The horizontal drive structure 2 transports the hardware parts to the stamping groove 7 of the leftmost mold base 6 through the vacuum suction cup 4. The vertical drive structure 9 is activated, which drives the stamping head 10 to punch the hardware parts below. The waste material from punching enters the stamping hole 8. After punching is completed, the vacuum suction cup 4 transports the punched hardware parts to the next processing position. The stamping head 10 stamps the hardware parts to form them. Then, the excess edges of the hardware parts are punched off at the rightmost processing position. The three processes can be carried out simultaneously to form a production line stamping, thereby realizing continuous stamping of hardware parts.

[0044] Furthermore, such as Figure 3 As shown, two first fixing plates 11 are fixedly connected to the top of the base plate 1. A feed plate 12 is rotatably connected between the two first fixing plates 11 by a pin. A fence is provided on the top of the feed plate 12. The feed plate 12 is inclined. The waste material from punching falls from the punching hole 8 onto the feed plate 12 and slides down along the feed plate 12.

[0045] Furthermore, such as Figure 2 and Figure 4As shown, a connecting rod 13 is fixedly connected to one of the connecting columns 3. A first semicircular block 14 is fixedly connected to the bottom end of the connecting rod 13. A connecting plate 15 is fixedly connected to one end of the feed plate 12. A second semicircular block 16 is fixedly connected to the top of the connecting plate 15. The second semicircular block 16 is located on the trajectory of the first semicircular block 14 as it moves with the vacuum suction cup 4. Two first springs 17 are fixedly connected to the top of the bottom plate 1. The top of the first springs 17 contacts the bottom of the feed plate 12. Waste material may accumulate on the feed plate 12 and cannot slide down. During the operation, the connecting column 3 will drive the connecting rod 13 to move, and the connecting rod 13 will drive the first semicircular block 14 to move, so that the first semicircular block 14 and the second semicircular block 16 come into contact. The first semicircular block 14 will press the second semicircular block 16 to move, and the second semicircular block 16 will drive the connecting plate 15 and the feeding plate 12 to rotate around the pin. The first spring 17 is compressed. When the vacuum suction cup 4 moves back, the first semicircular block 14 and the second semicircular block 16 will not come into contact. Under the action of the first spring 17, the feeding plate 12 will rotate back and forth around the pin, so that the waste material can slide down smoothly.

[0046] Furthermore, such as Figure 4 As shown, an impact block 18 is fixedly connected to the top of the connecting plate 15, and a rubber pad 19 is fixedly connected to the bottom of the feeding plate 12. The rubber pad 19 is located above the impact block 18. During the reciprocating rotation of the feeding plate 12, the feeding plate 12 drives the impact block 18 to impact the rubber pad 19 on the mold base 6. The impact generates vibration, which can be transmitted to the feeding plate 12, which is beneficial for the downward movement of waste material.

[0047] Furthermore, such as Figure 5 As shown, a draining rod 20 is fixedly connected to the feeding plate 12. The top end of the draining rod 20 is arc-shaped. The draining rod 20 is located below the punching hole 8, and the vertical surface of the draining rod 20 is close to the inner wall of the punching hole 8. When one end of the feeding plate 12 rotates upward, the feeding plate 12 drives the draining rod 20 to be inserted into the punching hole 8. The draining rod 20 can push against the waste material stuck in the punching hole 8, causing the waste material to fall down quickly.

[0048] Furthermore, such as Figure 5 As shown, a second fixing plate 21 is fixedly connected to the unblocking rod 20. A unblocking plate 22 is rotatably connected to the second fixing plate 21 via a pin. A second spring 23 is fixedly connected between the unblocking plate 22 and the unblocking rod 20. During the process of inserting the unblocking rod 20 into the punching hole 8, the unblocking plate 22 will be pressed by the waste material, and the second spring 23 will be compressed. After the unblocking plate 22 passes over the waste material, it will return to its original position under the action of the second spring 23. The unblocking plate 22 can help to hook out the waste material.

[0049] Furthermore, such as Figure 3 and Figure 4As shown, a third fixing plate 24 is fixedly connected to the side wall of the feeding plate 12. A guide rod 25 is slidably inserted on the third fixing plate 24. A movable plate 26 is fixedly connected to one end of the guide rod 25. A third spring 27 is fixedly connected between the movable plate 26 and the third fixing plate 24. The third spring 27 is sleeved on the outside of the guide rod 25. A rack 28 is fixedly connected to the movable plate 26. Multiple rotating rollers 29 are rotatably connected to the feeding plate 12 via bearings. A gear 30 is fixedly connected to one end of each rotating roller 29. The rack 28 meshes with the multiple gears 30. A fixing rod 31 is fixedly connected to one end of the rack 28. One end of the fixed rod 31 is fixedly connected to an arc-shaped rod 32, and the top of the base plate 1 is fixedly connected to a vertical plate 33. A fixed column 34 is fixedly connected to the vertical plate 33. The fixed column 34 is located on the trajectory of the arc-shaped rod 32 rotating around the pin shaft. During the reciprocating rotation of the feeding plate 12, the feeding plate 12 drives the arc-shaped rod 32 to move. The arc-shaped rod 32 will contact the fixed column 34, and the fixed column 34 will press the arc-shaped rod 32. With the cooperation of the third spring 27, the rack 28 can be made to reciprocate. The rack 28 drives multiple gears 30 to reciprocate. The gears 30 drive the rotating roller 29 to reciprocate. The rotating roller 29 can make the waste material slide down quickly.

[0050] Furthermore, such as Figure 6 and Figure 7 As shown, the surface of the rotating roller 29 is fixed with a plurality of rotating teeth 35. The tips of the top rotating teeth 35 face the feeding point of the feeding plate 12. The feeding plate 12 is provided with sponge blocks 36 located on both sides of the rotating roller 29. The rotating teeth 35 are provided with slots 37. A fourth spring 38 is fixedly connected in the slots 37. A fourth fixing plate 39 is fixedly connected to the top of the fourth spring 38. A roller 40 is rotatably connected to the fourth fixing plate 39 through a bearing. When the rotating roller 29 rotates counterclockwise, the rotating teeth 35 can push the waste material and accelerate the downward movement of the waste material. When the rotating roller 29 rotates clockwise, the roller 40 on the rotating teeth 35 will contact the waste material to prevent the friction between the rotating teeth 35 and the waste material from being too large and thus preventing the waste material from falling.

[0051] Furthermore, such as Figure 8 As shown, the third fixed plate 24 has a circular hole 41, and the guide rod 25 slides through the circular hole 41. During the movement of the moving plate 26 and the rack 28, the guide rod 25 slides in the circular hole 41, limiting the moving plate 26 and the rack 28 in the horizontal direction.

[0052] Working Principle: During operation, the hardware parts to be processed are neatly stacked on the left side of the equipment, positioned at the pick-up point. The horizontal drive structure 2 is activated, driving the vacuum suction cup 4 to move to the pick-up point. The vacuum suction cup 4 then holds the hardware parts, and the horizontal drive structure 2, via the vacuum suction cup 4, transports the hardware parts to the stamping groove 7 of the leftmost mold base 6. The vertical drive structure 9 is then activated, driving the stamping head 10 to punch holes in the hardware parts below. The waste material from the punching process enters the stamping hole 8. After punching, the vacuum suction cup 4 transports the punched hardware parts to the next processing position, where the stamping head 10 stamps and shapes the hardware parts. Finally, the hardware parts are processed at the rightmost processing position. Excess edges of the metal parts are punched off. These three processes can be performed simultaneously, forming an assembly line stamping system, thus achieving continuous stamping of the hardware parts. Scrap material from punching falls from the punching hole 8 onto the blanking plate 12. This scrap material may accumulate on the blanking plate 12 and fail to slide off. During the movement of the vacuum suction cup 4, the connecting column 3 drives the connecting rod 13, which in turn drives the first semicircular block 14, causing it to contact the second semicircular block 16. The first semicircular block 14 compresses the second semicircular block 16, causing it to move. The second semicircular block 16 then drives the connecting plate 15 and the blanking plate 12 to rotate around the pin, compressing the first spring 17. When the vacuum suction cup 4 moves back, the first semicircular block 14 and the second semicircular block 16 no longer contact each other. Under the action of the first spring 17, the feed plate 12 will reciprocate around the pin, allowing the scrap to slide down smoothly. During the reciprocating rotation of the feed plate 12, the feed plate 12 drives the impact block 18 to impact the rubber pad 19 on the mold base 6. The impact generates vibration, which can be transmitted to the feed plate 12, which is beneficial to the sliding of the scrap. When one end of the feed plate 12 rotates upward, the feed plate 12 drives the unblocking rod 20 to be inserted into the punching hole 8. The unblocking rod 20 can push against the scrap stuck in the punching hole 8, causing the scrap to fall down quickly. During the process of the unblocking rod 20 being inserted into the punching hole 8, the unblocking plate 22 will be pressed by the scrap, and the second spring 23 will be compressed. After the unblocking plate 22 passes over the scrap, it will return to its original position under the action of the second spring 23. In its original position, the unblocking plate 22 can assist in hooking out the waste. During the reciprocating rotation of the feeding plate 12, the feeding plate 12 drives the arc rod 32 to move. The arc rod 32 will contact the fixed column 34, and the fixed column 34 will press the arc rod 32. With the help of the third spring 27, the rack 28 can reciprocate. The rack 28 drives multiple gears 30 to reciprocate. The gears 30 drive the rotating roller 29 to reciprocate. The rotating roller 29 can make the waste slide down quickly. When the rotating roller 29 rotates counterclockwise, the rotating teeth 35 can push the waste and accelerate the slide down. When the rotating roller 29 rotates clockwise, the roller 40 on the rotating teeth 35 will contact the waste to prevent the friction between the rotating teeth 35 and the waste from being too large and thus preventing the waste from sliding down.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
