[0026] A stamping machine for sheet metal processing comprises the following steps:

[0027] S1. When stamping is required for metal plates, first stack the metal plates and place them flat in the bearing frame, and ensure that the stacked metal plates are in a neatly placed state. The servo motor drives the mounting sleeve to rotate, driving the connecting rod to rotate synchronously. The hinged transmission effect between the hinge seat and the push plate is utilized, and the sliding effect of the first guide sleeve on the guide rod is cooperated, so that the push plate moves within the moving track of the guide rod after being subjected to force. The elastic effect of the first spring is utilized to ensure that the push plate can always fit with the bottom surface of the metal plate when sliding in the channel, so that the push plate contacts the bottom surface of the metal plate placed at the bottom while sliding along the channel, and the push rod contacts the metal plate to push it, so that the metal plate placed at the bottom is pushed along the discharge chute to the load-bearing platform after being subjected to the thrust from the push rod;

[0028] S2. When the push rod completes the work of pushing the metal plate at the bottom, the installation sleeve continues to move in a circle. The elastic effect 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 is separated from the channel. When the installation sleeve rotates completely for one circle, 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. The metal plate falls onto the load-bearing platform after being pushed by the loading unit. The staff fine-tunes 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 load-bearing platform is stamped by the stamping machine body. After the stamping of the metal plate is completed, the pushing unit pushes the metal to the processing area.

[0030] S4, the sliding block driven by the cylinder moves horizontally along the slide rail after being stressed, so that the connecting plate moves synchronously after being stressed, and then drives the second guide rod and the second guide sleeve to move synchronously, so that the sliding rod moves along the guide frame after being stressed, so that the pusher bar contacts the load-bearing platform, and the metal plate after stamping is pushed out of the processing area by the pusher bar. The transmission effect of the connecting rod is used to make the brush roller move synchronously along the guide frame after being stressed. When the brush roller moves horizontally, the gear ring is meshed with the rack to realize the self-rotation of the brush roller during translation, and the brush roller cleans the waste chips on the top surface of the load-bearing platform;

[0031] S5. The metal plate is pushed by the push bar and falls into the lower hopper. The receiving plate provides a blocking effect for the metal plate. By pressing the handle downward, the receiving plate is turned along the axis of the rotating rod after being subjected to force, which makes it convenient to take the metal plate after the stamping process.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] (1) The present invention changes the traditional metal plate stamping feeding method through the setting of the feeding unit, which not only significantly improves the safety performance of the metal plate stamping processing work, but also can effectively avoid the potential safety hazards of accidental injury during the operation process. In addition, through the improved feeding method, it is possible to push a single metal plate into the processing area at a single time and at a uniform speed, thereby significantly improving the work efficiency of the metal plate stamping processing. It not only improves production safety, but also further optimizes the production process, making the entire metal plate stamping process more efficient and smooth, greatly improving production efficiency and product quality.

[0034] (2) The present invention can complete the unloading of metal plates with extremely high efficiency and stability through the setting of the pushing unit, which not only ensures that the metal plates can be unloaded quickly and accurately after the stamping process, but also significantly improves the overall production speed of the metal plate stamping process. The efficient unloading method can easily cope with the unloading needs of a large number of metal plates after stamping, ensuring the smooth progress of the metal plate stamping production process. At the same time, it also improves the production efficiency and economic benefits, making the entire production process more efficient and economical. By changing the unloading method of the metal plate after stamping, the common problem of metal plate retention in the traditional unloading method is successfully solved, which not only improves the production speed of the metal plate stamping process, but also reduces the potential losses caused by retention, thereby further improving the overall production efficiency and economic benefits.

[0035] (3) The present invention ensures that the brush roller can move smoothly along the inside of the guide frame when subjected to external force through the linkage arrangement of the waste cleaning component and the pushing unit, so that the brush roller can rotate while performing a translational movement. The combination of the self-rotation and movement of the brush roller can effectively and thoroughly clean the waste chips remaining from the stamping on the top surface of the load-bearing platform, and can directly avoid the situation where the next stamping effect is adversely affected by the stamping waste chips remaining on the load-bearing platform. In this way, not only the efficiency of the metal plate stamping work is improved, but also the stability and reliability of the stamping quality are ensured, and the overall metal plate stamping work effect is further improved, making the entire production process smoother and more efficient.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Example 1

[0050] See also Figure 1-Figure 11The stamping equipment for metal plate processing shown in the figure includes a stamping machine body 1 and a load-bearing platform 2 fixed on the stamping machine body 1, and also includes a load-bearing plate 5 fixed on the stamping machine body 1. One side wall adjacent to the load-bearing plate 5 and the load-bearing platform 2 is set with a chamfered slope. The chamfered slope on the load-bearing plate 5 allows the metal plate to be pushed onto the load-bearing platform 2 more smoothly. A bearing frame 4 is fixed on the load-bearing plate 5, and metal plates arranged in an even manner are placed in the bearing frame 4. A loading unit 3 matched with the metal plate is arranged on the load-bearing plate 5, and the loading unit 3 is used to push the metal plate placed in the bearing frame 4 to the processing area, and a pushing unit 6 is arranged on the load-bearing platform 2, and the pushing unit 6 is used to push the processed metal plate to the processing area. A blanking buffer mechanism 7 matched with the metal plate is arranged on the load-bearing platform 2, and the blanking buffer mechanism 7 is used to buffer the metal plate when it is blanked to avoid damage;

[0051] It should be noted that the stamping plate body is an existing product, and the stamping machine body 1 mainly includes a frame, a slider mechanism, a mold, a control system and a lubrication system. The slider 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 mold is an important tool for stamping processing. It plays a role in bearing the force of the workpiece and plastic deformation of the workpiece shape during stamping processing. According to the shape and number of the workpieces, the mold can be divided into a single-station, continuous multi-station, precision stamping mold, etc. The role of the lubrication system is to ensure the movement accuracy and life between the slider mechanism and the mold and the workpiece, and can reduce the metal healing phenomenon and the 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 size of the supporting frame 4 is consistent with the size of the metal plate. When the metal plate is stamped, the metal plates need to be neatly stacked and placed in the supporting frame 4. When the bottom metal plate is pushed into the processing area by force, the gravity of the upper metal plate is used to make the metal plate automatically fall down and contact the inner wall of the bottom end of the supporting frame 4, thereby achieving the purpose of automatic blanking of the metal plate.

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

[0054] S1. When stamping is required on metal plates, first stack the metal plates and place them flat in the supporting frame 4, and ensure that the stacked metal plates are in an orderly placed state. Driven by the servo motor 32, the mounting sleeve 33 rotates, driving the connecting rod 34 to rotate synchronously, utilizing the hinged transmission effect between the hinge seat 35 and the push plate 37, and cooperating with the sliding effect of the first guide sleeve 310 on the guide rod 39, so that the push plate 37 moves within the moving trajectory of the guide rod 39 after being subjected to force, utilizing the elastic effect of the first spring 36 to ensure that the push plate 37 can always fit with the bottom surface of the metal plate when sliding in the channel 312, so that the push plate 37 slides along the channel 312 and contacts the bottom surface of the metal plate placed at the bottom, and 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 chute 314 to the load-bearing platform 2 after being pushed by the push rod 313;

[0055] S2. After the push rod 313 completes the work of pushing the metal plate at the bottom, the mounting sleeve 33 continues to move in a circular motion. The push plate 37 is forced to move downward along the surface of the first guide rod 311 by the elastic effect of the first spring 36. At this time, the push plate 37 is separated from the channel 312. When the mounting sleeve 33 rotates completely for one circle, the servo motor 32 stops rotating. At this time, the push plate 37 is located in the channel 312, preparing for the next push of the metal plate.

[0056] S3, the metal plate is pushed by the feeding unit 3 and falls onto the load-bearing platform 2. The staff fine-tunes 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 load-bearing platform 2 is stamped by the punching machine body 1. After the stamping of the metal plate is completed, the pushing unit 6 pushes the metal to the processing area;

[0057] S4, the sliding block 62 driven by the cylinder 63 moves along the slide rail after being stressed, so that the connecting plate 64 moves synchronously after being stressed, and then 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 stressed, so that the pusher bar 611 contacts the load-bearing platform, and the metal plate after stamping is pushed out of the processing area by the pusher bar 611, and the brush roller 81 moves synchronously along the guide frame 610 after being stressed by the transmission effect of the connecting rod 82, and when the brush roller 81 moves in translation, the gear ring 83 is meshed with the rack 84, so that the brush roller 81 rotates when it moves in translation, and the brush roller 81 cleans the waste chips on the top surface of the load-bearing platform;

[0058] S5. The metal plate is pushed by the pushing bar 611 and falls into the lower hopper 71. The receiving plate 73 provides a blocking effect for the metal plate. By pressing the handle 12 downward, the receiving plate 73 is turned over along the axis of the rotating rod 72 after being subjected to force, so that the metal plate after the stamping process is conveniently taken out.

[0059] Embodiment 2: Based on Embodiment 1, according to Figure 3 , Figure 4 , Figure 7 , Figure 8 and Fig. 9 As shown, it is worth explaining in detail that the feeding unit 3 includes a support plate 31 fixed on the load-bearing plate 5, the angle between the support plate 31 and the load-bearing plate 5 is set at a right angle, and a servo motor 32 is fixed on the support plate 31, and a mounting sleeve 33 is fixed on the output shaft of the servo motor 32, the axis of the mounting sleeve 33 and the axis of the output shaft of the servo motor 32 are set in a colinear manner, the mounting sleeve 33 is set in a rectangular shape, and a connecting rod 34 slides through the mounting sleeve 33, and an articulated seat 35 is fixed at one end of the connecting rod 34 away from the mounting sleeve 33, a first spring 36 is sleeved on the connecting rod 34, and the two ends of the first spring 36 are respectively fixed to the mounting sleeve 33 and the articulated seat 35, as well as a push plate 37 hinged to the articulated seat 35, and the push plate 37 is rotatably connected to the articulated seat 35, and two mounting seats 38 are fixed on the load-bearing plate 5. A guide rod 39 is fixed on the mounting seat 38, and a first guide sleeve 310 is slidably sleeved on the guide rod 39. A first guide rod 311 that slides through the push plate 37 is fixed on the first guide sleeve 310, and 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 setting of the limiting ring 13 plays a role in limiting the first guide rod 311, so as to avoid the first guide rod 311 from falling off due to excessive movement and the push plate 37. There is also a channel 312 on the load-bearing plate 5, and the push plate 37 is slidably connected with the channel 312. Two push rods 313 are fixed on the push plate 37. A discharge groove 314 that matches the metal plate is provided on the bearing frame 4. The thickness of the discharge groove 314 is consistent with the thickness of the metal plate, so as to ensure that the metal plate can be smoothly pushed and discharged.

[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 circle, it stops automatically. The servo motor 32 can accurately control the rotation angle and speed of the output shaft by receiving the control signal of the servo controller. 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 circles, so that the output shaft of the servo motor 32 stops rotating automatically after rotating one circle, so as to keep the feeding speed of the metal plate at a constant speed, and the metal plate can be fed according to actual needs;

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

[0062] Example 3: Please refer to Figure 2 , Figure 6 , Figure 7 , Figure 8 and Fig.10 As shown, this embodiment further explains other embodiments. It is worth specifically explaining that the pushing unit 6 includes a mounting frame 61 fixed on the load-bearing platform 2, and a guide rail 9 is fixed in the mounting frame 61. A guide groove 10 matching the guide rail 9 is provided on the sliding block 62. The sliding block 62 slides on the guide rail 9, which can greatly improve the stability and smoothness of the sliding block 62 when it moves after being forced, and effectively avoids the displacement of the sliding block 62 when it moves, thereby improving the stability of the metal plate pushing effect. The length of the guide rail 9 is consistent with the length of the mounting frame 61, and the length of the mounting frame 61 is greater than the length of the load-bearing 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, so as to ensure that the metal plate can be completely pushed and separated from the load-bearing platform 2, and a cylinder 63 fixed to the sliding block 62 is installed on the mounting frame 61, and a protective outer The shell 11 can provide effective protection for the cylinder 63 through the setting of the protective shell 11, thereby significantly improving the service life of the cylinder 63, and 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, thereby ensuring the normal translation distance of the sliding block 62, and a connecting plate 64 is fixed on the sliding block 62, and a second guide rod 65 is slidably penetrated on the connecting plate 64, and 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, and the two ends of the second spring 66 are respectively fixed between the connecting ring 67 and the connecting plate 64, and a second guide sleeve 68 is fixed on the second guide rod 65, and a sliding rod 69 is rotatably connected in the second guide sleeve 68, and a guide frame 610 for sliding the sliding rod 69 is fixed on the load-bearing platform 2, and a pusher strip 611 is fixed on the sliding rod 69, and a waste chip cleaning component 8 matching the sliding rod 69 is provided in the guide frame 610;

[0063] It should be noted that, through the setting of the pushing unit 6, the task of unloading metal plates can be completed with high efficiency and stability. This process not only ensures that the metal plates can be unloaded quickly and accurately after the stamping process, but also greatly improves the overall production speed. In this way, it can easily cope with the unloading needs of a large number of metal plates after stamping processing, ensure the smooth progress of the metal plate stamping production process, and also improve production efficiency and economic benefits. By changing the unloading method of the metal plate after stamping, the problem of metal plate retention caused by the traditional unloading method affecting work efficiency is solved.

[0064] Further Figure 4 and Fig.11 As shown, it is worth to explain in detail that the waste cleaning assembly 8 includes a brush roller 81 slidably connected to the guide frame 610, a connecting rod 82 is hinged between the brush roller 81 and the slide bar 69, a gear ring 83 is fastened and sleeved on the brush roller 81, and a rack 84 is fixed on the guide frame 610, and the rack 84 cooperates with the gear ring 83;

[0065] It should be noted that, through the linkage between the waste chip cleaning assembly 8 and the pushing unit 6, it is ensured that the brush roller 81 can move smoothly along the inside of the guide frame after being acted upon by external force, so that the brush roller 81 can produce the necessary rotation effect while performing the translational movement. The combination of the rotation and movement of the brush roller 81 can effectively and thoroughly clean the waste chips remaining from the stamping on the top surface of the load-bearing platform 2. In this way, it is possible to directly avoid the situation where the next stamping effect is adversely affected by the stamping waste chips remaining on the load-bearing platform 2. In this way, not only the efficiency of the metal plate stamping work is improved, but also the stability and reliability of the stamping quality are ensured, thereby further improving the overall metal plate stamping work effect.

[0066] Example 4: Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.11 As shown, this embodiment further illustrates other embodiments. It is worth specifically explaining that the material drop buffer mechanism 7 includes a lower hopper 71 fixed on the load-bearing platform 2, a rotating rod 72 is rotatably connected in the lower hopper 71, a material receiving plate 73 is fixed on the rotating rod 72, a handle 12 is fixed on the material receiving plate 73, and an additional frame 74 fixed to the lower hopper 71 is fixed on the load-bearing platform 2, a rotating seat 75 is fixed between the material receiving plate 73 and the additional frame 74, and a spring damper 76 is fixed between the two rotating seats 75;

[0067] It should be noted that in the process of completing the stamping process of the metal plate, the setting of the blanking buffer mechanism 7, in which the receiving plate 73 plays a vital role, provides a solid blocking and buffering effect, and effectively prevents the metal plate from falling to the ground due to pushing after the processing is completed, thereby avoiding possible damage. This buffering effect not only ensures the safety of the metal plate during the production process, but also provides it with additional protection to ensure that it remains intact during subsequent transportation and storage.

[0068] In this scheme, when metal plates need to be stamped, the working principle of metal plate stamping is as follows:

[0069] First, the servo motor 32 is driven to rotate the mounting sleeve 33, driving the connecting rod 34 to rotate, and the hinged effect of the hinge seat 35 and the push plate 37 is utilized, and the setting of the first guide sleeve 310 sliding on the guide rod 39 is cooperated to ensure that the push plate 37 is translated within the moving trajectory defined on the guide rod 39 after being subjected to force, and the elastic effect of the first spring 36 is utilized to ensure that the push plate 37 can fit with the bottom surface of the metal plate when sliding in the channel 312, and the push rod 313 is utilized to move synchronously with the push plate 37, so that the lowest metal plate can be pushed out of the discharge chute 314 and dropped onto the load-bearing platform 2. When the lowest metal plate is pushed onto the load-bearing platform 2 by force, the gravity of the stacked metal plates is utilized to make the upper metal plate automatically fall, so that the mounting sleeve 33 can push a metal plate onto the load-bearing platform 2 every time it rotates one circle.

[0070] Secondly, the punching machine body 1 punches the metal plate. After the punching process is completed, the cylinder 63 drives the slider to move along the guide rail 9 after receiving force, and then drives the connecting plate 64 to move synchronously, so that the slide bar 69 moves along the guide frame 610 after receiving force, and the push bar 611 contacts the metal plate, thereby pushing the metal plate into the lower hopper 71;

[0071] Then, while the slide bar 69 is moving, the brush roller 81 is driven to move synchronously along the guide frame 610 by the transmission effect of the connecting rod 82, and the toothed ring 83 is in contact with the rack 84 to generate meshing transmission effect, so that the brush roller 81 is subjected to force and performs translational movement and self-rotation at the same time, and the brush roller 81 achieves the purpose of stamping the waste chips remaining on the load-bearing platform;

[0072] Finally, the metal plate pushed by the pushing bar 611 falls into the lower hopper 71, and the receiving plate 73 provides a blocking effect for the metal plate, and cooperates with the damping spring to effectively provide a buffering effect for the metal plate when the metal plate contacts and collides with the receiving plate 73. By pulling the handle 12, the receiving plate 73 is subjected to force and flipped along the axis of the rotating rod 72, which makes it convenient to take the metal plate after the stamping is completed.

[0073] The servo motor 32 and the cylinder 63 can both be purchased from the market and equipped with a separate power supply, which is a mature technology in this field and has been fully disclosed, so they will not be repeated in the specification.

When stamping is required on metal plates, the metal plates are first stacked and placed flat in the supporting frame (4), and the stacked metal plates are ensured to be neatly placed. The servo motor (32) is driven to rotate the mounting sleeve (33), driving the connecting rod (34) to rotate synchronously. The hinged transmission effect between the hinge seat (35) and the push plate (37) is utilized, and the sliding effect of the first guide sleeve (310) on the guide rod (39) is cooperated, so that the push plate (37) is subjected to force and moves on the guide rod (39). The push plate (37) moves within the moving track, and the elastic effect of the first spring (36) is used to ensure that the push plate (37) can always fit with the bottom surface of the metal plate when sliding in the channel (312), so that the push plate (37) slides along the channel (312) and contacts the bottom surface of the metal plate placed at the bottom, and the push rod (313) contacts the metal plate to push it, so that the metal plate placed at the bottom is pushed along the discharge chute (314) to the load-bearing platform (2) after receiving the thrust from the push rod (313); S2. When the push rod (313) completes the work of pushing the metal plate at the bottom, the mounting sleeve (33) continues to move in a circular motion. The push plate (37) is subjected to force and moves downward along the surface of the first guide rod (311) by utilizing the elastic action of the first spring (36). At this time, the push plate (37) is separated from the channel (312). When the mounting sleeve (33) rotates completely for one circle, 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, the metal plate is pushed by the loading unit (3) and falls onto the load-bearing platform (2). The staff fine-tunes 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 load-bearing 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 to the processing area; S4, the driving sliding block (62) of the cylinder (63) moves along the slide rail after being stressed, so that the connecting plate (64) moves synchronously after being stressed, and then 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 stressed, so that the pushing bar (611) contacts the load-bearing platform, and the pushing bar (611) pushes the stamped metal plate out of the processing area, and the transmission effect of the connecting rod (82) is used to make the brush roller (81) move synchronously along the guide frame (610) after being stressed. When the brush roller (81) moves in translation, the toothed ring (83) is meshed with the rack (84), so that the brush roller (81) rotates when it moves in translation, and the brush roller (81) cleans the waste chips on the top surface of the load-bearing platform; S5. The metal plate is pushed by the pushing bar (611) and falls into the lower hopper (71). The receiving plate (73) provides a blocking effect for the metal plate. By pressing the handle (12) downward, the receiving plate (73) is turned along the axis of the rotating rod (72) after being subjected to force, so that the metal plate after the stamping process is conveniently taken out.
