Technical Field

[0001] The present invention relates to the technical field of stamping machines, and specifically relates to a stamping machine with a clamping function. Background Art

[0002] A stamping machine is a mechanical device used to form, cut, bend, and process workpieces. It is very common in the manufacturing industry and is used to produce and process various parts and products.

[0003] The patent with the patent publication number CN29445267U relates to a cardboard opening stamping machine provided with a material pushing mechanism, including a workbench body. A placing groove is opened at the top of the workbench body, and two groups of placing grooves are provided. A pulley is slidably connected inside the placing groove, and two groups of pulleys are provided. A groove is also opened at the top of the workbench body, and two groups of grooves are provided. A material pushing mechanism is further provided inside the workbench body. The material pushing mechanism includes a first motor fixedly connected inside the workbench body. The output end of the first motor is fixedly connected with a driving roller, and two groups of driving rollers are provided. Through the settings of the first motor, the first lead screw, the electric push rod, the fixed block, and the threaded block, the function of material pushing processing without manual labor is realized, saving manpower, and solving the problem that most existing stamping machines have a single function and usually require manual placement of materials on the processing table when processing the processing materials, wasting manpower and affecting work efficiency.

[0004] In the above patent, it has the function of automatic material pushing. Through the combination of the first motor, the first lead screw, the electric push rod, the fixed block, and the threaded block, it solves the problem that existing stamping machines usually require operators to manually place materials on the processing table when processing the processing materials, saving manpower. However, in the automatic material pushing operation, if the positioning of the workpiece is inaccurate, it may cause the workpiece to be pushed into the processing area at an inappropriate position, and then the operator needs to intervene to reposition the workpiece, which will reduce the production efficiency. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a stamping machine with a clamping function, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A stamping machine with a clamping function includes a machine table, and a stamping mechanism is fixedly installed on the top of the machine table. It also includes a material pushing device; wherein, the material pushing device includes a base, a driving motor and a push plate, so that the output end of the driving motor moves towards the stamping mechanism, and the movement of the output end of the driving motor drives the push plate to move towards the stamping mechanism. The base is fixedly installed on the top of the machine table, the driving motor is fixedly installed on the top of the base, the push plate is fixedly installed on the output end of the driving motor, a support plate is fixedly penetrated through the bottom of the inner wall of the push plate, a contact block slides through the inner and outer walls of the top of the support plate, a rotating plate is rotatably installed on the inner wall surface of the support plate, the top of the contact block is subjected to pressure, so that the contact block moves downward, and the downward movement of the contact block drives the end of the rotating plate close to the contact block to rotate downward. A portal plate slides through the top of the support plate. A rectangular groove is formed on the surface of the push plate close to the driving motor, and a limiting groove is formed on the top of the base. Through the support of the support plate, the workpiece will not be scratched on the surface by the particles remaining on the surface of the machine table during movement, improving the processing quality.

[0007] According to the above technical solution, the bottom of the support plate contacts the surface of the machine table, and a first spring is arranged between the contact block and the support plate. The first spring is deformed under extrusion. The bottom of the contact block contacts the top of the rotating plate. Through the elasticity of the first spring itself, the extruded first spring automatically restores, thereby driving the clamping block to reset.

[0008] According to the above technical solution, a first volute spring is arranged between the rotating plate and the support plate. An arc surface one is formed at one end of the portal plate close to the rotating plate, and the arc surface one contacts the top of the rotating plate. The upward rotation of the rotating plate drives the portal plate to move upward. The surface of the portal plate contacts the inner wall of the rectangular groove, and one end of the portal plate close to the base contacts the inner wall of the limiting groove. Through the first volute spring, the rotating plate can be smoothly reset to the initial position after rotation, preparing for the next processing.

[0009] According to the above technical solution, a demoulding device and a positioning device are provided. The demoulding device includes a fixed table, a rotating rod and a rectangular plate. The rotation of the rotating rod deforms the second volute spring, and at the same time, the rotation of the rotating rod drives the rectangular plate to move. The fixed table is fixedly installed on the top of the machine table, the rotating rod is rotatably installed on the inner wall surface of the fixed table, the rectangular plate is fixedly installed on the surface of the rotating rod, an inclined surface one is formed on the surface of the fixed table close to the push plate, a docking groove is formed on the inclined surface one of the fixed table, and a hole groove is formed on the top of the fixed table. By the force of the upward movement of the rectangular plate to push the workpiece, the workpiece can be automatically separated from the stamping point after processing is completed, improving work efficiency.

[0010] According to the above technical solution, a T-shaped plate is hinged to the top of the rectangular plate, a sleeve is fixedly installed at the bottom of the inner wall of the fixed table, and a elastic sheet is fixedly installed on the inner wall surface of the sleeve. When the T-shaped plate moves downward, the surface of the T-shaped plate contacts the elastic sheet, causing the elastic sheet to deform. When the T-shaped plate continues to move and separates from the elastic sheet, the elastic sheet automatically resets due to its own elasticity. A linkage plate slides through the inner and outer walls of the sleeve. By the intermittent contact between the elastic sheet and the T-shaped plate, the moving speed of the T-shaped plate can be reduced, preventing damage to the workpiece caused by too fast speed when the T-shaped plate resets upward.

[0011] According to the above technical solution, a second scroll spring is provided between the rotating rod and the fixed table, and the second scroll spring deforms. The surface of the rectangular plate contacts the inner wall of the hole groove. A second spring is provided between the linkage plate and the sleeve. Due to the elasticity of the second spring itself, the deformed second scroll spring automatically resets, thereby driving the rotating rod to rotate and reset to the initial position, ensuring the stability during work.

[0012] According to the above technical solution, a second inclined surface is provided at the bottom of the T-shaped plate, and the elastic sheet has elasticity. When the elastic sheet deforms, the T-shaped plate continues to move and separates from the elastic sheet, and the elastic sheet automatically resets due to its own elasticity. An arc surface two is provided on the side of the linkage plate close to the sleeve. Due to the elasticity of the elastic sheet itself, the elastic sheet can be smoothly restored after deformation, extending the service life of the elastic sheet, thereby reducing the production cost.

[0013] According to the above technical solution, the positioning device includes a cylinder, a lifting table and a rubber ring. The moving end of the stamping mechanism drives the rubber ring to move downward, and the downward movement of the rubber ring drives the lifting table to move downward. The cylinder is fixedly installed on the top of the machine table, the lifting table is slidably installed on the surface of the cylinder, the rubber ring is fixedly installed on the top of the lifting table, and a round hole is provided on the lifting table. By the downward movement of the lifting table to contact the top of the workpiece, the top of the workpiece is subjected to pressure, ensuring that the workpiece does not shift during the processing.

[0014] According to the above technical solution, a short block slides through the bottom of the lifting table, a pressing plate is rotatably installed on the inner surface of the lifting table, and a moving block slides through the bottom of the lifting table. When the pressing plate rotates upward, the deformed fifth spring starts to reset, and the reset of the fifth spring drives the moving block to move upward. A button is fixedly installed at the bottom of the moving block, and the button is electrically connected to the control end of the stamping mechanism. By retracting the button into the interior of the lifting table when the positioning is successful, it is avoided that the button is accidentally triggered during the stamping operation.

[0015] According to the above technical solution, a spring three is arranged between the lifting platform and the cylinder, a spring four is arranged between the short block and the lifting platform, the spring four is deformed by being squeezed, a scroll spring No. 3 is arranged between the support plate and the lifting platform, and a spring five is arranged between the moving block and the lifting platform. Through the elasticity of the spring four itself, the deformed spring four can be automatically reset, thereby driving the short block to reset smoothly, ensuring that the short block is in the initial position during the next processing.

[0016] The present invention provides a punching machine with a clamping function, which has the following beneficial effects:

[0017] (1) In the punching machine with a clamping function, the output end of the driving motor moves to drive the push plate to move toward the punching mechanism, and the movement of the push plate drives the support plate to move toward the punching mechanism. By placing the workpiece on the support plate for pushing, it is prevented that the solid particles remaining in the machine table scratch the bottom of the workpiece during the pushing process, thereby affecting the processing appearance. The rotating plate rotates upward to drive the gate plate to move upward, and the gate plate moves upward and separates from the limit groove on the base, so that the base releases the movement limit of the gate plate, ensuring that the workpiece can be pushed only when it is fully in contact with the contact blocks on both sides, thereby ensuring the accurate positioning of the workpiece and reducing the risks to operators and equipment caused by incorrect workpiece position.

[0018] (2) In the punching machine with a clamping function, the rotating rod rotates upward to drive the rectangular plate to move upward. The rectangular plate moves upward and contacts the bottom of the workpiece, so that the rectangular plate moves upward and drives the workpiece to move upward, preventing the workpiece from being difficult to remove after the punching is completed. At the same time, the workpiece is effectively unloaded and automatically separated from the punching area, reducing the contact between the operator and the mechanical equipment and improving the safety of the work. When the T-shaped plate moves downward, the surface of the T-shaped plate contacts the spring sheet, causing the spring sheet to deform. The T-shaped plate continues to move and separates from the spring sheet. The elasticity of the spring sheet itself is used to limit the speed of the T-shaped plate moving up and down, ensuring that the speed of the T-shaped plate resetting upward is properly regulated, which helps to reduce the impact on the workpiece and reduces the possibility of damage to the workpiece.

[0019] (3) In the punching machine with a clamping function, the movement of the moving block drives the button to move downward, so that the top of the linkage plate contacts the button. After the button is triggered, the operation of the punching mechanism is stopped to prevent the punching mechanism from being accidentally started when the fixed table does not receive the workpiece, thereby avoiding unnecessary punching operations and helping to extend the life of the punching mechanism. The support plate rotates upward to allow the deformed spring five to begin to reset. The reset of the spring five drives the moving block to move upward. The moving block moves upward and drives the button to move upward. After the positioning is successful, the button automatically retracts into the interior of the lifting table, which can prevent the button from being accidentally triggered, thereby reducing the safety risks of operators and equipment.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-8, an embodiment of the present invention is: a stamping machine with a clamping function, including a machine table 1, a stamping mechanism 2 is fixedly installed on the top of the machine table 1, and a material pushing device is further included; wherein, the material pushing device includes a base 31, a driving motor 32 and a pushing plate 33. When the driving motor 32 is started, the output end of the driving motor 32 moves towards the stamping mechanism 2. The movement of the output end of the driving motor 32 drives the pushing plate 33 to move towards the stamping mechanism 2. The base 31 is fixedly installed on the top of the machine table 1, the driving motor 32 is fixedly installed on the top of the base 31, the pushing plate 33 is fixedly installed on the output end of the driving motor 32, a support plate 34 is fixedly penetrated through the bottom of the inner wall of the pushing plate 33, a contact block 35 is slidably penetrated through the inner and outer walls of the top of the support plate 34, a rotating plate 36 is rotatably installed on the inner wall surface of the support plate 34. When the workpiece is placed on the top of the support plate 34, the bottom of the workpiece contacts the top of the contact block 35. The top of the contact block 35 receives pressure, causing the contact block 35 to move downward. The downward movement of the contact block 35 drives the end of the rotating plate 36 close to the contact block 35 to rotate downward. A portal plate 37 is slidably penetrated through the top of the support plate 34. A rectangular groove is opened on the surface of the pushing plate 33 close to the driving motor 32, and a limiting groove is opened on the top of the base 31. Through the support of the support plate 34, the surface of the workpiece will not be scratched by the particles remaining on the surface of the machine table 1 during movement, improving the processing quality.

[0031] The bottom of the support plate 34 contacts the surface of the machine table 1. A first spring is arranged between the contact block 35 and the support plate 34. When the contact block 35 moves, the first spring is compressed and deformed. The bottom of the contact block 35 contacts the top of the rotating plate 36. Through the elasticity of the first spring itself, the compressed first spring automatically restores, thereby driving the clamping block to reset.

[0032] A first volute spring is arranged between the rotating plate 36 and the support plate 34. An arc surface 1 is opened at one end of the portal plate 37 close to the rotating plate 36. The arc surface 1 contacts the top of the rotating plate 36. The upward rotation of the end of the rotating plate 36 away from the contact block 35 drives the portal plate 37 to move upward. The surface of the portal plate 37 contacts the inner wall of the rectangular groove, and one end of the portal plate 37 close to the base 31 contacts the inner wall of the limiting groove. Through the first volute spring, the rotating plate 36 can be smoothly reset to the initial position after rotation, preparing for the next processing.

[0033] During the operation of this embodiment, manually place the workpiece on the top of the support plate 34, start the drive motor 32, and move the output end of the drive motor 32 towards the stamping mechanism 2. The movement of the output end of the drive motor 32 drives the push plate 33 to move towards the stamping mechanism 2, and the movement of the push plate 33 drives the support plate 34 to move towards the stamping mechanism 2. Through the support of the support plate 34, the surface of the workpiece will not be scratched by the particles remaining on the surface of the machine table 1 during movement, improving the processing quality. When the workpiece is placed on the top of the support plate 34, the bottom of the workpiece contacts the top of the contact block 35. The top of the contact block 35 is subjected to pressure, causing the contact block 35 to move downward. The downward movement of the contact block 35 drives the end of the rotating plate 36 close to the contact block 35 to rotate downward, and the end of the rotating plate 36 away from the contact block 35 rotates upward to drive the gantry plate 37 to move upward. The upward movement of the gantry plate 37 separates from the limiting groove on the base 31, releasing the movement limit of the base 31 on the gantry plate 37. By limiting the push plate 33, if an unexpected situation occurs when the workpiece is placed and the push plate 33 cannot move normally, the stability during work is improved.

[0034] Please refer to Figures 1-8 , on the basis of the above embodiment, in another embodiment of the present invention, it further includes a demoulding device and a positioning device. The demoulding device includes a fixed table 41, a rotating rod 42, and a rectangular plate 43. The movement of the support plate 34 drives the rotation of the rotating rod 42. The rotation of the rotating rod 42 deforms the second volute spring. At the same time, the rotation of the rotating rod 42 drives the movement of the rectangular plate 43. The fixed table 41 is fixedly installed on the top of the machine table 1. The rotating rod 42 is rotatably installed on the inner wall surface of the fixed table 41. The rectangular plate 43 is fixedly installed on the surface of the rotating rod 42. A first inclined surface is provided on one side of the fixed table 41 close to the push plate 33. A docking groove is provided on the first inclined surface of the fixed table 41. A hole groove is provided on the top of the fixed table 41. By the force of the upward movement of the rectangular plate 43 to push the workpiece, the workpiece can be automatically separated from the stamping point after processing, improving work efficiency.

[0035] A T-shaped plate 44 is hinged to the top of the rectangular plate 43. A sleeve 45 is fixedly installed at the bottom of the inner wall of the fixed table 41. A elastic piece 46 is fixedly installed on the inner wall surface of the sleeve 45. The rectangular plate 43 drives the T-shaped plate 44 to move downward. When the T-shaped plate 44 moves downward, the surface of the T-shaped plate 44 contacts the elastic piece 46, causing the elastic piece 46 to deform. The T-shaped plate 44 continues to move and separates from the elastic piece 46. The elastic piece 46 automatically resets due to its own elasticity. A linkage plate 47 slides through the inner and outer walls of the sleeve 45. Through the intermittent contact between the elastic piece 46 and the T-shaped plate 44, the moving speed of the T-shaped plate 44 can be reduced, preventing damage to the workpiece caused by the too fast upward reset speed of the T-shaped plate 44.

[0036] A second scroll spring is provided between the rotating rod 42 and the fixed table 41. When the rotating rod 42 rotates, the second scroll spring deforms. The surface of the rectangular plate 43 contacts the inner wall of the hole groove. A second spring is provided between the linkage plate 47 and the sleeve 45. Through the elasticity of the second spring itself, the deformed second scroll spring is automatically reset, thereby driving the rotating rod 42 to rotate and reset to the initial position, ensuring stability during operation.

[0037] The bottom of the T-shaped plate 44 is provided with a second inclined surface. The elastic piece 46 is elastic. The surface of the T-shaped plate 44 contacts the elastic piece 46, causing the elastic piece 46 to deform. The T-shaped plate 44 continues to move and separates from the elastic piece 46. The elastic piece 46 automatically resets due to its own elasticity. An arc-shaped surface two is provided on the side of the linkage plate 47 close to the sleeve 45. Through the elasticity of the elastic piece 46 itself, the elastic piece 46 can be smoothly restored after deformation, extending the service life of the elastic piece 46, thereby reducing production costs.

[0038] The positioning device includes a cylinder 51, a lifting table 52 and a rubber ring 53. When the moving end of the stamping mechanism 2 moves downward, it contacts the top of the rubber ring 53, causing the moving end of the stamping mechanism 2 to drive the rubber ring 53 to move downward. The downward movement of the rubber ring 53 drives the lifting table 52 to move downward. The cylinder 51 is fixedly installed on the top of the machine table 1. The lifting table 52 is slidably installed on the surface of the cylinder 51. The rubber ring 53 is fixedly installed on the top of the lifting table 52. A circular hole is provided on the lifting table 52. By moving the lifting table 52 downward to contact the top of the workpiece, the top of the workpiece is subjected to pressure, ensuring that the workpiece does not shift during processing.

[0039] A short block 54 slidably penetrates through the bottom of the lifting table 52. A resisting plate 55 is rotatably installed on the inner surface of the lifting table 52. A moving block 56 slidably penetrates through the bottom of the lifting table 52. The upward movement of the short block 54 drives the resisting plate 55 to rotate upward. The upward rotation of the resisting plate 55 causes the deformed fifth spring to start resetting. The resetting of the fifth spring drives the moving block 56 to move upward. A button 57 is fixedly installed at the bottom of the moving block 56. The button 57 is electrically connected to the control end of the stamping mechanism 2. By retracting the button 57 into the interior of the lifting table 52 when the positioning is successful, it is avoided that the button 57 is accidentally triggered during the stamping operation.

[0040] A third spring is provided between the lifting table 52 and the cylinder 51. A fourth spring is provided between the short block 54 and the lifting table 52. When the short block 54 moves, the fourth spring is squeezed and deformed. A third scroll spring is provided between the resisting plate 55 and the lifting table 52. A fifth spring is provided between the moving block 56 and the lifting table 52. Through the elasticity of the fourth spring itself, the deformed fourth spring can be automatically reset, thereby driving the short block 54 to reset smoothly, ensuring that the short block 54 is in the initial position during the next processing.

[0041] When the present embodiment is working, when the support plate 34 moves towards the stamping mechanism 2, the support plate 34 passes through the docking groove and moves into the interior of the fixed table 41. The support plate 34 continues to move and contacts the surface of the rotating rod 42, causing the support plate 34 to drive the rotating rod 42 to rotate. The rotation of the rotating rod 42 deforms the second scroll spring. At the same time, the rotation of the rotating rod 42 drives the rectangular plate 43 to move. As soon as the workpiece on the top of the support plate 34 contacts the inclined surface of the fixed table 41, the workpiece is pushed to move to the top of the fixed table 41. After stamping is completed, the support plate 34 moves in the direction of the driving motor 32 to reset. When the support plate 34 moves, it separates from the rotating rod 42, causing the rotating rod 42 to rotate upward to reset under the influence of the second scroll spring. The upward rotation of the rotating rod 42 drives the rectangular plate 43 to move upward. When the rectangular plate 43 moves upward and contacts the bottom of the workpiece, the bottom of the workpiece is subjected to a thrust, causing the rectangular plate 43 to move upward and drive the workpiece to move upward. By the force of the upward movement of the rectangular plate 43, the workpiece is pushed, enabling the workpiece to automatically separate from the stamping point after processing, improving work efficiency. While the rectangular plate 43 moves downward, the rectangular plate 43 drives the T-shaped plate 44 to move downward. When the T-shaped plate 44 moves downward, the surface of the T-shaped plate 44 contacts the elastic piece 46, causing the elastic piece 46 to deform. The T-shaped plate 44 continues to move and separates from the elastic piece 46, and the elastic piece 46 automatically resets due to its own elasticity. At the same time, the second inclined surface at the bottom of the T-shaped plate 44 contacts the second arc surface of the linkage plate 47, causing the T-shaped plate 44 to move downward and drive the linkage plate 47 to move away from the sleeve 45. Through the intermittent contact between the elastic piece 46 and the T-shaped plate 44, the moving speed of the T-shaped plate 44 can be reduced, preventing damage to the workpiece caused by the too-fast upward reset speed of the T-shaped plate 44;

[0042] Start the stamping mechanism 2 for positioning. When the mobile end of the stamping mechanism 2 moves downward, it contacts the top of the rubber ring 53, causing the mobile end of the stamping mechanism 2 to drive the rubber ring 53 to move downward. The downward movement of the rubber ring 53 drives the lifting platform 52 to move downward. When the lifting platform 52 moves downward, it drives the short block 54 to move downward. When the linkage plate 47 has moved away from the sleeve 45, the downward movement of the short block 54 contacts the top of the linkage plate 47. When the linkage plate 47 has not moved, the downward movement of the lifting platform 52 drives the moving block 56 to move downward. The movement of the moving block 56 drives the button 57 to move downward, causing the top of the linkage plate 47 to contact the button 57. After the button 57 is triggered, the operation of the stamping mechanism 2 stops. Through the movement of the linkage plate 47, when there is no workpiece on the fixed table 41, the stamping mechanism 2 cannot operate, reducing potential dangers and improving safety during work. After the top of the linkage plate 47 contacts the bottom of the short block 54, the lifting platform 52 continues to move, causing the bottom of the short block 54 to be resisted by the linkage plate 47, making the short block 54 move upward. The upward movement of the short block 54 drives the abutting plate 55 to rotate upward. The upward rotation of the abutting plate 55 causes the deformed spring five to start resetting. The resetting of spring five drives the moving block 56 to move upward. The upward movement of the moving block 56 drives the button 57 to move upward. By retracting the button 57 into the interior of the lifting platform 52 when the positioning is successful, the accidental triggering of the button 57 during the stamping operation is avoided, thereby improving the stamping efficiency.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
