Description

Technical Field

[0001] This invention relates to the field of metal sheet processing technology, specifically to stamping equipment and stamping methods for metal sheet processing. Background Technology

[0002] Stamping equipment for metal sheet processing is mainly used for forming and processing metal sheets. Common applications include stainless steel end cap stretching, stainless steel cover plate forming, stainless steel louver stamping, automotive exhaust pipe radiator cover, stainless steel centrifugal fan stretching, etc. Its advantages include rapid stretching, flexible and convenient mold replacement, low noise, fast stretching speed, high efficiency, low energy consumption, low operating noise, adjustable stretching speed, and multi-purpose functionality.

[0003] Currently, most metal sheet stamping equipment uses manual feeding, where the metal sheet to be stamped is placed in the stamping area and then stamped by the equipment. However, manual feeding is inefficient and time-consuming, making it difficult to meet the demand for stamping large quantities of metal sheets.

[0004] Chinese Patent Publication No. CN113953366A discloses a stamping device and method for metal sheet processing, relating to the field of metal sheet processing technology.

[0019] A rack is fixed on the guide frame, and the rack engages with a gear ring.

[0020] Preferably, the material feeding buffer mechanism includes:

[0025] Preferably, the side wall of the load-bearing plate adjacent to the load-bearing platform is provided with a chamfered slope, and the inner side wall of the guide frame is provided with a chamfered arc surface.

[0026] The stamping equipment for metal sheet processing includes the following steps:

[0027] S1. When stamping a metal plate, first stack the metal plates flat in the bearing frame and ensure that the stacked metal plates are neatly placed. Driven by the servo motor, the mounting sleeve rotates, which drives the connecting rod to rotate synchronously. Utilizing the hinge transmission between the hinge seat and the push plate, and with the sliding action of the first guide sleeve on the guide rod, the push plate moves within the movement trajectory of the guide rod after being subjected to force. Utilizing the elasticity of the first spring, it is ensured that the push plate can always be in contact with the bottom surface of the metal plate when sliding in the channel, so that the push plate contacts the bottom surface of the bottom metal plate while sliding in the channel. The push rod contacts the metal plate and pushes it, so that the bottom metal plate is pushed along the discharge groove to the bearing platform after being pushed by the push rod.

[0028] S2. When the push rod finishes pushing the bottom metal plate, the mounting sleeve continues to rotate. The elasticity of the first spring causes the push plate to move downward along the surface of the first guide rod after being subjected to force. At this time, the push plate separates from the channel. When the mounting sleeve has rotated one full revolution, the servo motor stops rotating. At this time, the push plate is located in the channel, preparing for the next push of the metal plate.

[0029] S3. After being pushed by the feeding unit, the metal plate falls onto the support platform. The staff will fine-tune the position of the metal plate according to the actual stamping work requirements. After the position of the metal plate is adjusted, the metal plate on the support platform will be stamped by the stamping machine body. After the stamping of the metal plate is completed, the pushing unit will push the metal to the processing area.

[0030] S4. Driven by the cylinder, the sliding block moves along the guide rail after being subjected to force, causing the connecting plate to move synchronously after being subjected to force. This, in turn, drives the second guide rod and the second guide sleeve to move synchronously, causing the sliding rod to move along the guide frame after being subjected to force. This causes the pusher bar to contact the load-bearing platform, and the pusher bar pushes the stamped metal plate to the outside of the processing area. Utilizing the transmission action of the connecting rod, the brush roller moves synchronously along the guide frame after being subjected to force. When the brush roller moves in translation, the toothed ring and the rack mesh to achieve the rotation of the brush roller during translation, and the brush roller cleans the waste on the top surface of the load-bearing platform.

[0031] S5. The metal plate is pushed by the pusher bar and falls into the hopper. The receiving plate provides a blocking effect for the metal plate. By pressing down the handle, the receiving plate is rotated along the axis of the rotating rod after being subjected to force, making it easy to pick up the metal plate after the stamping process is completed.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] This invention, through the design of the feeding unit, changes the traditional method of feeding metal sheet in stamping. This not only significantly improves the safety performance of metal sheet stamping, but also effectively avoids potential safety hazards such as accidental injury during operation. Furthermore, the improved feeding method enables a single metal sheet to be pushed into the processing area at a uniform speed in one go, thereby significantly improving the efficiency of metal sheet stamping. This not only enhances production safety but also further optimizes the production process, making the entire metal sheet stamping process more efficient and smooth, and greatly improving production efficiency and product quality.

[0034] This invention, through the design of the feeding unit, enables the cutting of metal sheets with extremely high efficiency and stability. It not only ensures that the metal sheets are cut quickly and accurately after the stamping process, but also significantly improves the overall production speed of metal sheet stamping. The efficient cutting method can easily handle the cutting needs of large quantities of stamped metal sheets, ensuring the smooth operation of the metal sheet stamping production process. At the same time, it improves production efficiency and economic benefits, making the entire production process more efficient and economical. By changing the cutting method after metal sheet stamping, it successfully solves the common problem of metal sheet retention in traditional cutting methods. This not only increases the production speed of metal sheet stamping but also reduces potential losses caused by retention, thereby further improving overall production efficiency and economic benefits.

[0035] This invention, through the coordinated design of the waste removal component and the feeding unit, ensures that the brush roller can move smoothly along the inside of the guide frame when subjected to external force. This allows the brush roller to rotate while performing translational movement. The combination of rotation and movement of the brush roller can effectively and thoroughly clean the stamping residue on the top surface of the support platform. This directly avoids the situation where stamping residue left on the support platform will adversely affect the next stamping effect. In this way, not only is the efficiency of metal sheet stamping improved, but the stability and reliability of stamping quality are also ensured, further enhancing the overall metal sheet stamping effect and making the entire production process smoother and more efficient.

Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1

[0050] Please see Figure 1 - Figure 11The metal sheet stamping equipment shown in the figure includes a stamping machine body 1 and a support platform 2 fixed on the stamping machine body 1, as well as a support plate 5 fixed on the stamping machine body 1. The side wall of the support plate 5 adjacent to the support platform 2 is set with a chamfered slope. The chamfered slope on the support plate 5 allows the metal sheet to be pushed onto the support platform 2 more smoothly. A support frame 4 is fixed on the support plate 5, and the support frame 4 contains neatly arranged metal sheets. A feeding unit 3 that cooperates with the metal sheet is set on the support plate 5, and the feeding unit 3 is used to push the metal sheet placed in the support frame 4 to the processing area. A pushing unit 6 is set on the support platform 2, and the pushing unit 6 pushes the metal sheet out of the processing area. A dropping buffer mechanism 7 that cooperates with the metal sheet is set on the support platform 2, and the dropping buffer mechanism 7 is used to buffer the metal sheet to avoid damage when it is being dropped.

[0051] It should be noted that the stamping plate body is an existing product. The stamping machine body 1 mainly includes a frame, a slide mechanism, a die, a control system, and a lubrication system. The slide mechanism is the core component of the stamping machine body 1. Its movement applies pressure to the metal parts and completes processing methods such as punching, cutting, stretching, and bending. The die is an important tool in stamping processing. In stamping processing, it plays the role of bearing the force of the workpiece and plastically deforming the shape of the workpiece. According to the shape and quantity of the processed parts, the die can be divided into single-station, continuous multi-station, and precision stamping dies. The function of the lubrication system is to ensure the movement accuracy and life of the slide mechanism and the die and the workpiece. It can reduce metal healing phenomenon and workpiece burr effect to achieve precise control of metal plate stamping. This is a conventional setting in this field, so it will not be described in detail here.

[0052] It should also be noted that the dimensions of the supporting frame 4 are the same as the dimensions of the metal plate. When stamping the metal plate, the metal plate needs to be neatly stacked and placed inside the supporting frame 4. When the bottom metal plate is pushed into the processing area by force, the weight of the upper metal plate will cause the metal plate to fall automatically and contact the inner wall of the bottom end of the supporting frame 4, thereby achieving the purpose of automatic unloading of the metal plate.

[0053] In this solution, the stamping method for metal sheet processing includes the following steps:

[0054] S1. When the metal plate needs to be stamped, the metal plate is first stacked flat in the bearing frame 4, and the stacked metal plates are placed in a neat position. Driven by the servo motor 32, the mounting sleeve 33 rotates, which drives the connecting rod 34 to rotate synchronously. Using the hinge transmission between the hinge seat 35 and the push plate 37, and with the sliding action of the first guide sleeve 310 on the guide rod 39, the push plate 37 moves within the movement trajectory of the guide rod 39 after being subjected to force. Using the elastic action of the first spring 36, it is ensured that the push plate 37 can always be in contact with the bottom surface of the metal plate when sliding in the channel 312, so that the push plate 37 contacts the bottom surface of the metal plate placed at the bottom while sliding in the channel 312. The push rod 313 contacts the metal plate and pushes it, so that the metal plate placed at the bottom is pushed along the discharge groove 314 to the bearing platform 2 after being pushed by the push rod 313.

[0055] S2. After the pusher rod 313 completes the push of the bottom metal plate, when the mounting sleeve 33 continues to rotate, the pusher plate 37 is forced to move downward along the surface of the first guide rod 311 by the elastic action of the first spring 36. At this time, the pusher plate 37 is separated from the channel 312. After the mounting sleeve 33 has rotated one full revolution, the servo motor 32 stops rotating. At this time, the pusher plate 37 is located in the channel 312, preparing for the next push of the metal plate.

[0056] S3. After being pushed by the feeding unit 3, the metal plate falls onto the support platform 2. The staff will finely adjust the position of the metal plate according to the actual stamping work requirements. After the position adjustment of the metal plate is completed, the metal plate on the support platform 2 will be stamped by the stamping machine body 1. After the stamping of the metal plate is completed, the pushing unit 6 will push the metal plate out of the processing area.

[0057] S4. Driven by cylinder 63, sliding block 62 moves along guide rail 9 under force, causing connecting plate 64 to move synchronously under force, which in turn drives second guide rod 65 and second guide sleeve 68 to move synchronously, causing slide rod 69 to move along guide frame 610 under force, causing push bar 611 to contact the load-bearing platform. Push bar 611 pushes the stamped metal plate to the outside of the processing area. Using the transmission action of connecting rod 82, brush roller 81 moves synchronously along guide frame 610 under force. When brush roller 81 moves in translation, toothed ring 83 meshes with rack 84 to make brush roller 81 rotate during translation, and brush roller 81 cleans waste from the top surface of the load-bearing platform.

[0058] S5. The metal plate is pushed by the pusher bar 611 and falls into the hopper 71. The receiving plate 73 provides a blocking effect for the metal plate. By pressing down the handle 12, the receiving plate 73 is subjected to force and flips along the axis of the rotating rod 72, making it easy to pick up the metal plate after the stamping process is completed.

[0059] Example 2: Based on Example 1, according to Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown, it is worth noting that the feeding unit 3 includes a support plate 31 fixed on the load-bearing plate 5. The support plate 31 and the load-bearing plate 5 are set at a right angle. A servo motor 32 is fixed on the support plate 31. A mounting sleeve 33 is fixed on the output shaft of the servo motor 32. The axis of the mounting sleeve 33 is collinear with the axis of the output shaft of the servo motor 32. The mounting sleeve 33 is rectangular in shape, and a connecting rod 34 slides through the mounting sleeve 33. A hinge seat 35 is fixed at the end of the connecting rod 34 away from the mounting sleeve 33. A first spring 36 is sleeved on the connecting rod 34. The two ends of the first spring 36 are fixed to the mounting sleeve 33 and the hinge seat 35, respectively. A pusher plate 37 is hinged to the hinge seat 35, and the pusher plate 37 is rotatably connected to the hinge seat 35. Two mounting seats 38 are fixed on the load-bearing plate 5. A guide rod 39 is fixed on the seat 38. A first guide sleeve 310 is slidably sleeved on the guide rod 39. A first guide rod 311 is fixed on the first guide sleeve 310 and slides through the pusher plate 37. A limiting ring 13 is fixed on the first guide rod 311. The diameter of the limiting ring 13 is larger than the diameter of the first guide rod 311. The limiting ring 13 limits the first guide rod 311 and prevents the first guide rod 311 from falling off the pusher plate 37 due to excessive movement. A channel 312 is opened on the load-bearing plate 5, and the pusher plate 37 is slidably connected to the channel 312. Two pusher rods 313 are fixed on the pusher plate 37. A discharge groove 314 that cooperates with the metal plate is opened on the load-bearing frame 4. The thickness of the discharge groove 314 is the same as the thickness of the metal plate to ensure that the metal plate can be smoothly pushed out.

[0060] It should be noted that the servo motor 32 is equipped with a servo controller. When the servo motor 32 drives the output shaft to rotate one revolution, it will automatically stop. By receiving the control signal from the servo controller, the servo motor 32 can precisely control the rotation angle and speed of the output shaft. By adjusting the number of pulses or the pulse frequency of the control signal, the servo motor 32 can be controlled to rotate a specific angle or number of revolutions, so that the output shaft of the servo motor 32 will automatically stop rotating after one revolution. This achieves the goal of keeping the metal plate feeding speed constant, and the metal plate feeding operation can be performed according to actual needs.

[0061] It should also be noted that the setting of the feeding unit 3 has successfully changed the traditional metal sheet stamping feeding method. This innovative measure not only significantly improves the safety performance of metal sheet stamping, but also effectively avoids potential safety hazards of accidental injury during operation. In addition, this improved feeding method can realize the single and uniform pushing of a single metal sheet into the processing area, thereby significantly improving the working efficiency of metal sheet stamping. This improvement not only improves production safety, but also further optimizes the production process, making the entire metal sheet stamping process more efficient and smooth.

[0062] Example 3: Please refer to Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, this embodiment further illustrates other embodiments. Specifically, the pushing unit 6 includes a mounting frame 61 fixed to the support platform 2. A guide rail 9 is fixed inside the mounting frame 61. A guide groove 10 cooperating with the guide rail 9 is provided on the sliding block 62. By sliding the sliding block 62 on the guide rail 9, the stability and smoothness of the sliding block 62 when moving under force can be greatly improved, effectively preventing displacement of the sliding block 62 during movement, thereby improving the stability of pushing the metal plate. The length of the guide rail 9 is the same as the length of the mounting frame 61, and the length of the mounting frame 61 is greater than the length of the support platform 2. The sliding block 62 is slidably connected to the mounting frame 61, and the length of the mounting frame 61 is the moving length of the sliding block 62, thus ensuring that the metal plate can be completely pushed away from the support platform 2. A cylinder 63 fixed to the sliding block 62 is mounted on the mounting frame 61, and a protective outer casing is fixed on the cylinder 63. The protective shell 11 provides effective protection for the cylinder 63, thereby significantly improving the service life of the cylinder 63. The protective shell 11 is fixed to the mounting frame 61, and the maximum stroke of the cylinder 63 is greater than the length of the mounting frame 61, thus ensuring the normal translation distance of the sliding block 62. A connecting plate 64 is fixed on the sliding block 62, and a second guide rod 65 slides through the connecting plate 64. A second spring 66 is sleeved on the second guide rod 65, and a connecting ring 67 is fixed on the second guide rod 65. The two ends of the second spring 66 are fixed between the connecting ring 67 and the connecting plate 64, respectively. A second guide sleeve 68 is fixed on the second guide rod 65, and a sliding rod 69 is rotatably connected inside the second guide sleeve 68. A guide frame 610 is fixed on the support platform 2 to allow the sliding rod 69 to slide. A pusher bar 611 is fixed on the sliding rod 69, and a waste cleaning component 8 that cooperates with the sliding rod 69 is provided inside the guide frame 610.

[0063] It should be noted that the pusher unit 6 enables the efficient and stable cutting of metal sheets. This process not only ensures that the metal sheets can be cut quickly and accurately after the stamping process, but also greatly improves the overall production speed. This makes it easy to meet the cutting needs of a large number of metal sheets after stamping, ensuring the smooth operation of the metal sheet stamping production process, while also improving production efficiency and economic benefits. By changing the cutting method of the metal sheets after stamping, the problem of metal sheet retention and its impact on work efficiency caused by the traditional cutting method is solved.

[0064] Further as Figure 4 and Figure 11 As shown, it is worth noting that the waste cleaning assembly 8 includes a brush roller 81 that is slidably connected to the guide frame 610, a connecting rod 82 that is hinged between the brush roller 81 and the slide rod 69, a toothed ring 83 that is fastened to the brush roller 81, and a rack 84 that is fixed to the guide frame 610, and the rack 84 cooperates with the toothed ring 83.

[0065] It should be noted that the linkage between the waste cleaning component 8 and the pushing unit 6 ensures that the brush roller 81 can move smoothly along the inside of the guide frame after being subjected to external force. This allows the brush roller 81 to generate the necessary rotation effect while performing translational movement. The combination of the rotation and movement of the brush roller 81 can effectively clean the waste residue left on the top surface of the support platform 2. This directly avoids the situation where the waste residue left on the support platform 2 will have an adverse effect on the next stamping effect. In this way, not only is the efficiency of metal sheet stamping improved, but the stability and reliability of stamping quality are also ensured, thereby further improving the overall metal sheet stamping effect.

[0066] Example 4: Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 11 As shown, this embodiment further illustrates other embodiments. It is worth noting that the material feeding buffer mechanism 7 includes a feeding hopper 71 fixed on the support platform 2. A rotating rod 72 is rotatably connected inside the feeding hopper 71. A receiving plate 73 is fixed on the rotating rod 72. A handle 12 is fixed on the receiving plate 73. An mounting frame 74 fixed to the feeding hopper 71 is fixed on the support platform 2. A rotating seat 75 is fixed between the receiving plate 73 and the mounting frame 74. A spring damper 76 is fixed between the two rotating seats 75.

[0067] It should be noted that during the stamping process of the metal sheet, the receiving plate 73 plays a crucial role in the material feeding buffer mechanism 7, providing a sturdy barrier and buffering effect. This effectively prevents the metal sheet from falling to the ground after processing, thus avoiding potential damage. This buffering effect not only ensures the safety of the metal sheet during the production process but also provides additional protection, ensuring that it remains intact during subsequent handling and storage.

[0068] In this solution, when metal sheet stamping is required, the working principle of the metal sheet stamping process is as follows:

[0069] First, the mounting sleeve 33 is rotated by the servo motor 32, which in turn rotates the connecting rod 34. The hinge seat 35 and the pusher plate 37 are hinged together, and the first guide sleeve 310 slides on the guide rod 39. This ensures that the pusher plate 37 moves within the movement trajectory defined on the guide rod 39 after being subjected to force. The elasticity of the first spring 36 ensures that the pusher plate 37 can fit against the bottom surface of the metal plate when sliding in the channel 312. The pusher rod 313 moves synchronously with the pusher plate 37, so that the bottom metal plate can be pushed out of the discharge trough 314 and fall onto the support platform 2. When the bottom metal plate is pushed onto the support platform 2, the weight of the stacked metal plates causes the upper metal plate to fall automatically. This achieves the purpose of pushing a metal plate onto the support platform 2 with each rotation of the mounting sleeve 33.

[0070] Secondly, the metal plate is stamped by the press body 1. After the stamping of the metal plate is completed, the slide is driven by the cylinder 63 to move along the guide rail 9 after being subjected to force, which in turn drives the connecting plate 64 to move synchronously. This causes the slide rod 69 to move along the guide frame 610 after being subjected to force, and the pusher bar 611 contacts the metal plate, thereby pushing the metal plate into the hopper 71.

[0071] Then, while the slide bar 69 moves, the connecting rod 82 drives the brush roller 81 to move synchronously along the guide frame 610. The toothed ring 83 and the rack 84 engage to drive the brush roller 81, which rotates while being subjected to force. The brush roller 81 removes the waste residue left by the stamping at the load-bearing platform.

[0072] Finally, the metal plate pushed by the pusher bar 611 falls into the hopper 71, and the receiving plate 73 provides a blocking effect for the metal plate. In conjunction with the damping spring, it effectively provides a buffer when the metal plate comes into contact with the receiving plate 73. By pulling the handle 12, the receiving plate 73 is subjected to force and flips along the axis of the rotating rod 72, making it easy to pick up the stamped metal plate.

7. A stamping method for metal sheet processing, applied to the stamping equipment for metal sheet processing as described in claim 6, characterized in that, Includes the following steps: S1. When stamping a metal plate, first stack the metal plates flat in the support frame (4) and ensure that the stacked metal plates are neatly placed. Driven by the servo motor (32), the mounting sleeve (33) rotates, which drives the connecting rod (34) to rotate synchronously. Utilizing the hinge transmission between the hinge seat (35) and the pusher plate (37), and in conjunction with the sliding action of the first guide sleeve (310) on the guide rod (39), the pusher plate (37) is subjected to force and moves on the guide rod (39). The pusher plate (37) moves within the movement trajectory. The elastic action of the first spring (36) ensures that the pusher plate (37) can always be in contact with the bottom surface of the metal plate when sliding in the channel (312). This allows the pusher plate (37) to slide along the channel (312) and contact the bottom surface of the metal plate placed at the bottom. The pusher rod (313) contacts the metal plate and pushes it, causing the metal plate placed at the bottom to be pushed along the discharge groove (314) to the support platform (2) after being pushed by the pusher rod (313). S2. When the push rod (313) finishes pushing the bottom metal plate, the mounting sleeve (33) continues to rotate. The elasticity of the first spring (36) causes the push plate (37) to move downward along the surface of the first guide rod (311) after being subjected to force. At this time, the push plate (37) separates from the channel (312). After the mounting sleeve (33) has rotated one full revolution, the servo motor (32) stops rotating. At this time, the push plate (37) is located in the channel (312) to prepare for the next push of the metal plate. S3. After being pushed by the feeding unit (3), the metal plate falls onto the support platform (2). The staff will finely adjust the position of the metal plate according to the actual stamping work requirements. After the position adjustment of the metal plate is completed, the metal plate on the support platform (2) is stamped by the stamping machine body (1). After the stamping of the metal plate is completed, the pushing unit (6) pushes the metal plate to the outside of the processing area. S4. After the sliding block (62) driven by the cylinder (63) is subjected to force, it moves along the guide rail (9) and the connecting plate (64) moves synchronously after being subjected to force. Then, it drives the second guide rod (65) and the second guide sleeve (68) to move synchronously, so that the sliding rod (69) moves along the guide frame (610) after being subjected to force, causing the push bar (611) to contact the load-bearing platform. The push bar (611) pushes the stamped metal plate to the outside of the processing area. Using the transmission action of the connecting rod (82), the brush roller (81) moves synchronously along the guide frame (610) after being subjected to force. When the brush roller (81) moves in translation, the toothed ring (83) and the rack (84) mesh to realize the rotation of the brush roller (81) when it moves in translation. The brush roller (81) cleans the waste on the top surface of the load-bearing platform. S5. The metal plate is pushed by the push bar (611) and falls into the hopper (71). The receiving plate (73) provides a blocking effect for the metal plate. By pressing down the handle (12), the receiving plate (73) is subjected to force and flips along the axis of the rotating rod (72), making it easy to pick up the metal plate after the stamping process is completed.
