Description

Technical Field

[0001] The present invention relates to the technical field of stamping devices, and in particular to a component stamping device and a method for using the same. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. For machine production, it includes the transportation and storage of raw materials, preparation for production, manufacturing of blanks, processing and heat treatment of parts, etc. Among them, parts and components are the units that constitute the overall equipment processing and the products that serve the processing of equipment accessories. They are the foundation of the mechanized industry. Most of the existing parts and components are made by combining stamping equipment and molds. Stamping is a common processing and shaping method for metal accessories. Stamping is an important metal forming process. It is based on the principle of metal plastic deformation. It uses molds and stamping equipment to apply pressure to metal sheets to cause plastic deformation, thereby obtaining parts with certain shapes, sizes and performances. When performing metal stamping, metal processing equipment needs to be applied.

[0003] After searching, the existing patent (Announcement No.: CN220497547U) discloses a parts stamping equipment, including a punch, a base and a fixed seat installed in parallel on the upper end of the base, and a limiting frame is symmetrically arranged on the base between the two fixed seats. In the patent document, the plate to be processed is placed between the baffles. During the contact between the punch and the plate to be processed, the first workbench and the second workbench are hinged at the connection to limit the plate to be processed. After the stamping is completed, the support structure resets the second workbench and the first workbench, which can constrain the plate to be processed during stamping and improve the stamping quality.

[0004] However, in the above scheme, after the stamping of the processed sheet is completed, manual unloading is required, which not only has low work efficiency, but also has the safety hazard of hand injury. After searching, the existing patent (Announcement No.: CN118577685A) discloses a mechanical parts stamping equipment and method. When the stamping equipment is used, the worker uses his hands to place the blank in the cavity of the half-die, and starts the die to press the blank through the controller. After the die stamping is completed, the die is lifted up by the controller to reset the die. The first cylinder pulls the half-die to both sides of the workbench to move the two half-dies away from each other to realize the demolding of the stamped parts. Under the action of gravity, the stamped parts fall into the collection trough through the through slot of the workbench for collection, and the stamped parts are taken out.

[0005] In the above solution, although it is possible to avoid manually grasping and discharging the workpiece formed by stamping, during its operation, the cylinder needs to be driven by a controller, and the separation and combination of the half die are realized by the push and pull of the cylinder. The operation is rather troublesome, and manual electric control operation is required. The equipment has a high usage cost and poor linkage. It cannot automatically constrain and limit the workpiece to be die-cast during the lower die-casting process to improve the die-casting quality, and it cannot realize the automatic discharging of the workpiece after die-casting.

[0006] In view of this, the present invention proposes a parts stamping equipment and its usage method. Summary of the Invention

[0016] Preferably, the blanking mechanism further includes a cross bar. The cross bar is slidably sleeved inside the track groove. The two ends of the cross bar are respectively fixedly connected to the outer walls of the lifting blocks on the two blanking mechanisms. A pushing plate is fixedly connected to the middle of the cross bar. T-shaped grooves for the sliding of the T-shaped sliding table are opened inside the first fixing table and the second fixing table. A return spring is fixedly connected between the T-shaped sliding table and one end of the T-shaped groove.

[0017] Preferably, the linkage mechanism includes a connecting shaft rotatably connected to the outer wall of the U-shaped frame. One end of the triangular frame hinged to the U-shaped frame is fixedly connected to the connecting shaft. A first pulley is fixedly sleeved on the outer wall of the end of the connecting shaft close to the U-shaped frame. An installation block is fixedly connected to the side wall of the U-shaped frame. A second pulley is rotatably connected to the outer wall of the installation block. A transmission belt is connected between the second pulley and the first pulley for transmission.

[0018] Preferably, the linkage mechanism includes a connecting shaft fixedly connected to the outer wall of the second pulley. Winding disks are fixedly sleeved at both ends of the connecting shaft. A traction rope is wound inside the winding disk. The traction rope extends into the T-shaped groove and is connected to the T-shaped sliding table.

[0019] Preferably, the linkage mechanism further includes a rope bundling member. The traction rope slidably penetrates through the rope bundling member. An L-shaped block is fixedly connected to the port of the T-shaped groove. The rope bundling member fixedly penetrates through the L-shaped block.

[0020] A method for stamping parts includes the following steps:

[0021] Step 1: Place the workpiece to be pressed on the upper ends of the first fixed table and the second fixed table between two guiding and limiting plates. Limit and constrain two ends of the workpiece to be pressed through the two guiding and limiting plates. Then, turn on the power supply and start the electro-hydraulic device. The electro-hydraulic device moves the push rod downward through its hydraulic rod. The push rod presses the stamping head downward, so as to stamp and form the workpiece to be pressed.

[0022] Step 2: During the downward movement of the push rod, the push rod drives the sleeve block to move downward. The sleeve block pushes two triangular frames through two connecting rods, so that the triangular frames turn outward on the outer wall of the U-shaped frame. Under the guiding and constraining of the connecting plate, the triangular frames push the swing plates, so that the two swing plates move downward and approach each other, so that the two clamping components move downward and approach each other.

[0023] Step 3: When the rollers at the bottom of the rear seat frame move downward and contact the first fixed table and the second fixed table, with the assistance of the rollers, drive the rear seat frame to move on the upper sides of the first fixed table and the second fixed table. As the two swing plates continue to approach, the swing plates extend into the inner side of the rear seat frame. Compress the top support spring through the limiting strip. The mutually approaching clamping components can move between the two guiding and limiting plates through the two front plates to push and center and limit the other two ends of the workpiece to be pressed.

[0024] Step 4: During the downward movement of the push rod, while the triangular frame flips outward, it drives the coupling shaft to rotate clockwise. The coupling shaft drives the first pulley to rotate, and the first pulley drives the second pulley to rotate through the transmission belt. It should be noted that the diameter of the first pulley is larger than that of the second pulley, so that the rotational speed of the second pulley is greater than that of the first pulley. The second pulley drives the two winding disks to rotate synchronously clockwise through the series connection shaft, and the two winding disks synchronously pull the two traction ropes, so that the traction ropes quickly pull the T-shaped slide table to move rightward;

[0025] Step 5: During the rightward movement of the T-shaped slide table, the return spring can be stretched. The T-shaped slide table drives the lifting block to move, and the lifting block drives the cross bar to move rightward. Under the action of the track groove opened inside the guiding and limiting plate, the cross bar drives the pushing plate to move along the trajectory of upward movement → translational movement → downward movement → translational movement. The lifting block slides up and down adaptively inside the T-shaped slide table through balls, and moves the pushing plate to the rightmost area of the workbench. The purpose of setting the track groove is that when the pushing plate moves rightward, it will not push the workpiece to be pressed placed between the two guiding and limiting plates, so that the position of the workpiece to be pressed is shifted;

[0026] Step 6: After the punching head presses down and finishes punching the workpiece to be pressed, the electro-hydraulic device drives the push rod to move upward through its hydraulic rod. Under the action of the sleeve block and the connecting rod, the triangular frame is pulled, so that the two triangular frames flip inward, thereby causing the coupling shaft to rotate counterclockwise and releasing the traction rope. At this time, under the action of the return spring, the T-shaped slide table is pulled to move leftward and reset. When the pushing plate moves to the left half section of the guiding and limiting plate, the pushing plate can push the workpiece folded by punching to the left, so that the punched and formed workpiece falls into the blanking frame through the material leakage cavity for guiding blanking;

[0027] Step 7: Then place the workpiece to be pressed between the two guiding and limiting plates and continue the next round of punching work.

[0028] The working principle and beneficial effects of the present invention are as follows:

[0029] 1. In the present invention, by providing a guiding and limiting plate at the upper ends of the first fixed table and the second fixed table respectively, the two ends of the workpiece to be pressed can be limited and constrained. By providing a transmission and limiting mechanism, during the process of pressing the die-casting by the push rod, under the combined action of the sleeve block, two connecting rods, two triangular frames, a U-shaped frame, a connecting plate and a swing plate, the two clamping components move downward and approach each other. When the rollers at the bottom of the rear seat frame move downward to contact the first fixed table and the second fixed table, with the assistance of the rollers, the rear seat frame is driven to move on the upper sides of the first fixed table and the second fixed table, and the swing plate extends towards the inside of the rear seat frame, and can move between the two guiding and limiting plates through the two front plates to push and center-align the other two ends of the workpiece to be pressed. It realizes the automatic centering and limiting of the workpiece to be pressed during the die-casting process, prevents the position of the workpiece from shifting, and improves the forming quality of the parts;

[0030] 2. In the present invention, a linkage mechanism is provided on one side of the transmission and limiting mechanism. A blanking mechanism is provided on each of the first fixed table and the second fixed table. A material leakage cavity is jointly opened between the first fixed table and the second fixed table. The first fixed table and the second fixed table are jointly fixedly connected with a blanking frame at the bottom. During the process of the punching head punching the workpiece to be pressed, the transmission and limiting mechanism can drive the linkage mechanism, so that the two winding discs on the linkage mechanism rotate synchronously clockwise. The two winding discs synchronously pull the two traction ropes, so that the traction ropes quickly pull the T-shaped sliding table to move rightward. Under the guidance of the track groove, the cross bar drives the pushing plate to quickly move rightward along the trajectory of moving upward → translating → moving downward → translating, which will not cause the position of the workpiece to be pressed placed between the two guiding and limiting plates to shift, and will not affect the die-casting work of the push rod and the punching head;

[0031] 3. In the present invention, when the punching head moves downward and finishes punching the workpiece to be pressed, when the electro-hydraulic device drives the push rod to move upward through its hydraulic rod, under the action of the sleeve block and the connecting rod, the triangular frames are pulled, so that the two triangular frames turn inward, thereby causing the coupling shaft to rotate counterclockwise and release the traction rope. At this time, under the action of the return spring, the T-shaped sliding table is pulled to move leftward to reset. When the pushing plate moves to the left half section of the guiding and limiting plate, the pushing plate can push the workpiece folded by punching to the left, so that the punched and formed workpiece falls into the blanking frame through the material leakage cavity for guiding blanking, realizing the automatic blanking work of the formed workpiece during the punching process, improving the punching efficiency, avoiding the safety hazard of being injured by hand during blanking, and having high use value.

[0060] Embodiment 2

[0061] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8 , a component stamping device and its usage method, including all the contents of Embodiment 1. In addition, a linkage mechanism 4 is arranged on one side of the transmission and limit mechanism 5, and a blanking mechanism 6 is arranged on each of the first fixed platform 81 and the second fixed platform 82. A blanking cavity 86 is jointly opened between the first fixed platform 81 and the second fixed platform 82 for blanking the workpiece formed by stamping with the stamping head 22. A blanking frame 84 is jointly fixed at the bottoms of the first fixed platform 81 and the second fixed platform 82 for receiving the workpiece falling from the blanking cavity 86. During the process of the stamping head 22 stamping the workpiece to be pressed 9, the transmission and limit mechanism 5 can drive the linkage mechanism 4, so that the linkage mechanism 4 can drive the blanking mechanism 6, and then the formed workpiece can be pushed into the blanking cavity 86.

[0062] Specifically, the blanking mechanism 6 includes a T-shaped sliding table 63. An elevating block 62 is slidably sleeved inside the T-shaped sliding table 63. A ball 68 is rotatably sleeved on each side of the elevating block 62. A ball groove 69 for the ball 68 to move is opened inside the T-shaped sliding table 63. A guide rod 61 is vertically fixed inside the T-shaped sliding table 63. The guide rod 61 slidably penetrates through the inside of the elevating block 62. A support spring 65 is sleeved on the outer side of the guide rod 61 above the elevating block 62.

[0063] Further, the blanking mechanism 6 further includes a cross bar 67. The cross bar 67 is slidably sleeved inside the track groove 71. The two ends of the cross bar 67 are respectively fixedly connected to the outer walls of the lifting blocks 62 on the two blanking mechanisms 6. A pushing plate 66 is fixedly connected to the middle of the cross bar 67. T-shaped grooves 85 for the T-shaped sliding table 63 to slide are provided inside both the first fixing platform 81 and the second fixing platform 82. A return spring 64 is fixedly connected between the T-shaped sliding table 63 and one end of the T-shaped groove 85.

[0064] Specifically, the linkage mechanism 4 includes a connecting shaft 41 rotatably connected to the outer wall of the U-shaped frame 1. One end of the triangular frame 53 hinged to the U-shaped frame 54 is fixedly connected to the connecting shaft 41. A first belt pulley 42 is fixedly sleeved on the outer wall of the end of the connecting shaft 41 close to the U-shaped frame 1. An installation block 45 is fixedly connected to the side wall of the U-shaped frame 1. A second belt pulley 43 is rotatably connected to the outer wall of the installation block 45. A transmission belt 44 is connected between the second belt pulley 43 and the first belt pulley 42 for transmission.

[0065] Further, the linkage mechanism 4 includes a series connection shaft 47 fixedly connected to the outer wall of the second belt pulley 43. Reel discs 46 are fixedly sleeved at both ends of the series connection shaft 47. A traction rope 48 is wound inside the reel disc 46. The traction rope 48 extends into the T-shaped groove 85 and is connected to the T-shaped sliding table 63.

[0066] Furthermore, the linkage mechanism 4 further includes a rope bundling member 49. The traction rope 48 slidably penetrates through the inside of the rope bundling member 49. An L-shaped block is fixedly connected to the port of the T-shaped groove 85. The rope bundling member 49 fixedly penetrates through the inside of the L-shaped block.

[0067] In this embodiment, during the downward movement of the push rod 21, while the triangular frame 53 flips outwards, it will drive the connecting shaft 41 to rotate clockwise. The connecting shaft 41 drives the first belt pulley 42 to rotate. The first belt pulley 42 drives the second belt pulley 43 to rotate through the transmission belt 44. It should be noted that the diameter of the first belt pulley 42 is larger than that of the second belt pulley 43, so that the rotation speed of the second belt pulley 43 is greater than that of the first belt pulley 42. The second belt pulley 43 drives the two reel discs 46 to rotate synchronously clockwise through the series connection shaft 47. The two reel discs 46 synchronously pull the two traction ropes 48, so that the traction ropes 48 quickly pull the T-shaped sliding table 63 to move rightwards.

[0068] In this embodiment, during the rightward movement of the T-shaped slide 63, the return spring 64 can be stretched. The T-shaped slide 63 drives the lifting block 62 to move, and the lifting block 62 drives the cross bar 67 to move rightward. Under the action of the track groove 71 formed inside the guiding and limiting plate 7, the cross bar 67 drives the pushing plate 66 to move along the trajectory of upward movement → translational movement → downward movement → translational movement. The lifting block 62 slides up and down adaptively inside the T-shaped slide 63 through the balls 68, and moves the pushing plate 66 to the rightmost area of the workbench 8. The purpose of setting the track groove 71 is that when the pushing plate 66 moves rightward, it will not push the workpiece 9 to be pressed placed between the two guiding and limiting plates 7, so as to prevent the position of the workpiece 9 to be pressed from shifting. After the punching head 22 presses down to complete the punching of the workpiece 9 to be pressed, the electro-hydraulic device 2 drives the push rod 21 to move upward through its hydraulic rod. Under the action of the sleeve block 51 and the connecting rod 52, the triangular frame 53 is pulled, so that the two triangular frames 53 are turned inward, thereby causing the coupling shaft 41 to rotate counterclockwise and releasing the traction rope 48. At this time, under the action of the return spring 64, the T-shaped slide 63 is pulled to move leftward and reset. When the pushing plate 66 moves to the left half section of the guiding and limiting plate 7, the pushing plate 66 can push the punched and folded workpiece to the left, so that the punched and formed workpiece falls into the blanking frame 84 through the material leakage cavity 86 for guiding blanking.

[0069] Working principle and usage process: First, place the workpiece 9 to be pressed on the upper ends of the first fixed table 81 and the second fixed table 82 between the two guiding and limiting plates 7, and limit and constrain two ends of the workpiece 9 to be pressed through the two guiding and limiting plates 7. Then, turn on the power supply and start the electro-hydraulic device 2. The electro-hydraulic device 2 drives the push rod 21 to move downward through its hydraulic rod, and the push rod 21 presses down the punching head 22, so as to punch and form the workpiece 9 to be pressed.

[0070] During the downward movement of the push rod 21, the push rod 21 drives the sleeve block 51 to move downward. The sleeve block 51 pushes the two triangular frames 53 through the two connecting rods 52, so that the triangular frames 53 are turned outward on the outer wall of the U-shaped frame 54. Under the guiding constraint of the connecting plate 55, the triangular frames 53 push the swing plates 56, so that the two swing plates 56 move downward and approach each other, thereby causing the two clamping assemblies 57 to move downward and approach each other. When the rollers 575 at the bottom of the rear seat frame 571 move downward to contact the first fixed table 81 and the second fixed table 82, with the assistance of the rollers 575, the rear seat frame 571 is driven to move on the upper sides of the first fixed table 81 and the second fixed table 82. As the two swing plates 56 continue to approach, the swing plates 56 extend into the inner side of the rear seat frame 571, compress the top support spring 577 through the limiting strip 576. The mutually approaching clamping assemblies 57 can move between the two guiding and limiting plates 7 through the two front plates 572, and push and center-align the other two ends of the workpiece 9 to be pressed for limiting.

[0071] Moreover, during the downward movement of the push rod 21, while the triangular frame 53 flips outwards, it drives the coupling shaft 41 to rotate clockwise. The coupling shaft 41 drives the first pulley 42 to rotate. The first pulley 42 drives the second pulley 43 to rotate through the transmission belt 44. It should be noted that the diameter of the first pulley 42 is larger than that of the second pulley 43, so that the rotational speed of the second pulley 43 is greater than that of the first pulley 42. The second pulley 43 drives the two winding disks 46 to rotate synchronously clockwise through the series connection shaft 47. The two winding disks 46 synchronously pull the two traction ropes 48, so that the traction ropes 48 quickly pull the T-shaped slide 63 to move rightward. During the rightward movement of the T-shaped slide 63, the return spring 64 can be stretched. The T-shaped slide 63 drives the lifting block 62 to move. The lifting block 62 drives the cross bar 67 to move rightward. Under the action of the track groove 71 opened in the guiding and limiting plate 7, the cross bar 67 drives the pushing plate 66 to move along the trajectory of upward movement → translational movement → downward movement → translational movement. The lifting block 62 slides up and down adaptively inside the T-shaped slide 63 through the balls 68, and moves the pushing plate 66 to the rightmost area of the workbench 8. The purpose of setting the track groove 71 is that when the pushing plate 66 moves rightward, it will not push the workpiece to be pressed 9 placed between the two guiding and limiting plates 7, so that the position of the workpiece to be pressed 9 is shifted.

[0072] After the stamping head 22 presses down to complete the stamping of the workpiece to be pressed 9, the electro-hydraulic device 2 drives the push rod 21 to move upward through its hydraulic rod. Under the action of the sleeve block 51 and the connecting rod 52, the triangular frame 53 is pulled, so that the two triangular frames 53 flip inwards, thereby causing the coupling shaft 41 to rotate counterclockwise and releasing the traction rope 48. At this time, under the action of the return spring 64, the T-shaped slide 63 is pulled to move leftward and reset. When the pushing plate 66 moves to the left half of the guiding and limiting plate 7, the pushing plate 66 can push the stamped and folded workpiece to the left, so that the stamped and formed workpiece falls into the blanking frame 84 through the blanking cavity 86 for guiding blanking. Then, the workpiece to be pressed 9 is placed between the two guiding and limiting plates 7 to continue the next round of stamping work.

10. A method for stamping parts, using any one of the parts stamping devices as claimed in claims 1-9, characterized in that, It includes the following steps: Step 1: Place the workpiece to be pressed (9) on the upper ends of the first fixed platform (81) and the second fixed platform (82) between the two guiding and limiting plates (7). Limit and restrain two ends of the workpiece to be pressed (9) through the two guiding and limiting plates (7). Then, turn on the power supply and start the electric hydraulic actuator (2). The electric hydraulic actuator (2) moves down the push rod (21) through its hydraulic rod. The push rod (21) presses down the punching head (22), so as to punch and form the workpiece to be pressed (9). Step 2: During the process of the push rod (21) pressing down, the push rod (21) drives the sleeve block (51) to move down. The sleeve block (51) pushes the two triangular frames (53) through the two connecting rods (52), so that the triangular frames (53) are turned outwards on the outer wall of the U-shaped bracket (54). Under the guiding and restraint of the connecting plate (55), the triangular frames (53) push the swing plates (56), so that the two swing plates (56) move downwards and approach each other, so that the two clamping assemblies (57) move downwards and approach each other. Step 3: When the roller (575) at the bottom of the rear seat frame (571) moves downward to contact the first fixed platform (81) and the second fixed platform (82), with the assistance of the roller (575), the rear seat frame (571) is driven to move on the upper sides of the first fixed platform (81) and the second fixed platform (82). As the two swing plates (56) continue to approach, the swing plates (56) extend into the inner side of the rear seat frame (571), and the top support spring (577) is compressed by the limiting strip (576). The mutually approaching clamping assemblies (57) can move between the two guide limiting plates (7) through the two front plates (572) to push, center, and limit the other two ends of the workpiece to be pressed (9). Step 4: During the downward movement of the push rod (21), while the triangular frame (53) flips outward, it drives the coupling shaft (41) to rotate clockwise. The coupling shaft (41) drives the first pulley (42) to rotate. The first pulley (42) drives the second pulley (43) to rotate through the transmission belt (44). It should be noted that the diameter of the first pulley (42) is larger than that of the second pulley (43), so that the rotational speed of the second pulley (43) is greater than that of the first pulley (42). The second pulley (43) drives the two winding discs (46) to rotate synchronously clockwise through the series connection shaft (47). The two winding discs (46) synchronously pull the two traction ropes (48), so that the traction ropes (48) quickly pull the T-shaped slide (63) to move rightward. Step 5: During the rightward movement of the T-shaped slide (63), the return spring (64) can be stretched. The T-shaped slide (63) drives the lifting block (62) to move. The lifting block (62) drives the cross bar (67) to move rightward. Under the action of the track groove (71) opened inside the guide limiting plate (7), the cross bar (67) drives the push plate (66) to move along the trajectory of upward movement → translational movement → downward movement → translational movement. The lifting block (62) slides up and down adaptively inside the T-shaped slide (63) through the balls (68), and moves the push plate (66) to the rightmost area of the workbench (8). The purpose of setting the track groove (71) is that when the push plate (66) moves rightward, it will not push the workpiece to be pressed (9) placed between the two guide limiting plates (7), so as to prevent the position of the workpiece to be pressed (9) from shifting. Step Six: After the stamping head (22) presses down to complete the stamping of the workpiece to be pressed (9), the electro-hydraulic device (2) drives the push rod (21) to move upward through its hydraulic rod. Under the action of the sleeve block (51) and the connecting rod (52), the triangular frame (53) is pulled, causing the two triangular frames (53) to flip inward, thereby causing the coupling shaft (41) to rotate counterclockwise and releasing the traction rope (48). At this time, under the action of the return spring (64), the T-shaped sliding table (63) is pulled to move leftward for reset. When the pushing plate (66) moves to the left half section of the guiding and limiting plate (7), the pushing plate (66) can push the workpiece folded by stamping to the left, enabling the stamped workpiece to fall into the blanking frame (84) through the blanking cavity (86) for guiding blanking; Step Seven: Then, place the workpiece to be pressed (9) between the two guiding and limiting plates (7) and continue the next round of stamping work.
