Description

Technical Field

[0001] The present application relates to the technical field of automation equipment, and in particular to a punching mechanism and device. Background Art

[0002] Punching is a key step in some production processes. Common punching methods include punching, laser punching, drilling, etc.

[0003] Punching is often used to punch holes in thin workpieces, such as sheet metal and plastic parts. The punching mechanism in related technologies includes a cylinder and a punch head connected to one end of the cylinder's piston rod. When a hole is needed, the cylinder drives the punch head to punch the desired hole in the thin workpiece.

[0004] In order to ensure stamping accuracy, it is generally necessary to set up an additional fixed structure on the stamping platform to fix the workpiece, which makes the overall structure complicated and the operation cumbersome; and because the workpiece is a thin plate, local stamping can easily cause deformation, affecting the structure around the process hole, and the quality of the formed process hole does not meet expectations. Utility Model Content

[0005] The present application provides a punching mechanism and device to solve the current technical problems of inaccurate punching and poor forming quality.

[0006] In the first aspect, the present application provides a punching mechanism having a first direction, comprising: a bracket; a driving member, arranged on the bracket, the driving member having a moving part that moves back and forth along the first direction; a stamping assembly, arranged on the moving part, the stamping assembly including a base and a pressing head arranged on the base, the pressing head having a stamping surface facing away from the base; and a limiting assembly, arranged on the base, the limiting assembly including a limiting member and an elastic member, the limiting member is slidably sleeved on the outside of the pressing head along the first direction, and in the first direction, the elastic member is arranged between the limiting member and the base; wherein, in the natural state of the elastic member, the limiting member is partially located on the side of the stamping surface away from the base, and in the compressed state of the elastic member, the limiting member is located on the side of the stamping surface close to the base.

[0007] To implement the above technical solution, the stamping process is as follows: the driving member drives the stamping assembly to move toward the workpiece along the first direction, and the limiting assembly moves with the base, so that the limiting member first contacts the workpiece, and as the driving member drives the base to continue to move, the base compresses the elastic member so that the limiting member is pressed against the workpiece, and the above process realizes the preliminary fixation of the workpiece through the limiting assembly; then the driving member drives the ram to continue to move until the ram punches a process hole on the workpiece. In the solution of the embodiment of the present application, the workpiece is preliminarily fixed by the limiting assembly before the ram contacts the workpiece, thereby ensuring the stability of the workpiece and improving the accuracy of the punching hole; and, since the limiting member is sleeved on the outside of the ram, the position where the limiting member is pressed is near the area to be punched, achieving more accurate compaction and shaping, thereby making the deformation of the part of the workpiece to be punched smaller, further improving the accuracy of the punching, and the limiting member shields the influence of the ram on the workpiece in the area around the ram when punching, further ensuring the quality of the punching hole.

[0008] As an optional embodiment of the present application, it also includes a fixing member, which is fixedly arranged on the base; wherein, the outer wall of the limiting member has a protrusion, and the fixing member has a stop portion, and in the first direction, the stop portion is arranged on the side of the protrusion away from the base; one end of the elastic member abuts the limiting member, and the other end of the elastic member abuts the base.

[0009] To implement the above technical solution, the two ends of the elastic part in this embodiment have no fixed connection with the limit part and the base, which is conducive to the disassembly and maintenance of the elastic part, etc. However, when the first direction is from top to bottom, that is, when the first direction is the direction of gravity, this connection method will cause the limit part to slide from the outside of the pressure head, causing the limit part to contact the workpiece, etc., resulting in inconvenience in operation. Therefore, a fixed sleeve is designed to limit the displacement of the limit part along the first direction. At this time, the elastic part can choose to abut the limit part and the base at both ends respectively, instead of being fixedly connected. At this time, the elastic part only plays the role of providing elastic force, reducing fatigue damage to the elastic part and improving its service life.

[0010] As an optional embodiment of the present application, the fixing member is provided with a through groove extending along the first direction and passing through the fixing member, and the stop portion is protruded from the inner wall of the through groove at one end away from the base; the limiting member includes a first set and a second set connected to each other along the first direction, the outer diameter of the first set is larger than the outer diameter of the second set, and the protruding portion of the first set forms a convex portion compared to the protruding portion of the second set; the first set is slidably arranged in the through groove.

[0012] By implementing the above technical solution, the fixing part can be removed from the base, and the elastic part and the limit part can also be removed from the base, which is convenient for modular disassembly and assembly of the components. In particular, after a certain period of use, the elasticity of the elastic part may be fatigue-damaged. At this time, the elastic part can be easily replaced to ensure the accuracy of the crimping force on the workpiece.

[0013] As an optional embodiment of the present application, one end of the elastic member is fixedly connected to the base, and the other end of the elastic member is fixedly connected to the limiting member.

[0014] To implement the above technical solution, a specific structure for connecting the limiter and the base is proposed. The limiter is fixedly connected to the base through an elastic member. The elastic member not only provides elastic force in the first direction to make the limiter move elastically in the first direction, but also the elastic member connects the limiter and the base at the same time, thereby ensuring that the base can drive the limiter away from the workpiece when it is away from the workpiece.

[0015] As an optional embodiment of the present application, a mounting hole extending and passing through along a first direction is provided on the base, and the pressure head is plugged into and installed in the mounting hole; wherein, a fastening groove is recessed in the outer wall of the pressure head, and a fastening screw is threadedly provided on the base, and one end of the fastening screw is plugged into and fitted with the fastening groove.

[0016] To implement the above technical solution, the design of the fastening groove and the fastening screw makes the pressure head and the base detachable, which is convenient for the maintenance and replacement of the pressure head; and this structural design is also convenient for installation, which is conducive to the overall modular assembly design of the punching mechanism.

[0017] As an optional embodiment of the present application, an air duct is provided in the pressure head, one end of the air duct passes through the stamping surface and communicates with the outside world, and the other end of the air duct is connected to the air inlet connector.

In the first direction, the bracket has a relative top plate and bottom plate, and the guide assembly is arranged between the bottom plate and the base. The guide assembly includes a guide sleeve arranged on the base, a guide rod arranged on the bottom plate, and a buffer member arranged on the outer wall of the guide rod. The guide sleeve is slidably mounted on the guide rod.

[0020] By implementing the above technical solution, the guide assembly can provide the base with precise limiting and guiding functions, so that the stamping position is more accurate and the quality of the stamping hole is guaranteed.

[0021] As an optional embodiment of the present application, the waste collecting assembly comprises a collecting sleeve and a collecting bag connected to the collecting sleeve, the collecting sleeve is arranged on the side of the bottom plate away from the base, and the bottom plate is provided with a material falling through hole in communication with the collecting sleeve, and the collecting sleeve is detachably connected to the bottom plate.

[0022] The collecting sleeve and the collecting bag can timely collect impurities, and the scraps, separated burrs and stamping waste can directly fall into the collecting bag from the material falling through hole along the collecting sleeve, so that the processing environment is kept clean, and the impurities are prevented from polluting the product.

Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0049] In the description of this application, it should be noted that, unless otherwise specified or limited, the term "and / or" herein is merely a description of an association relationship between associated objects, indicating that three possible relationships exist.

[0050] Punching is a key step in many production processes. Common punching methods include stamping, laser drilling, drilling, and so on. For example, in the field of consumer electronics, precise punching operations are required in the battery production process of electronic devices such as tablets and laptops. Stamping is mostly used to perform punching operations on thin plate workpieces. For example, sheet metal parts, plastic parts, etc. The punching mechanism in the related art includes a cylinder and a punch head connected to one end of the cylinder piston rod. When punching is required, the cylinder is operated to drive the punch head to punch out the required process holes on the thin plate product. In order to ensure the stamping accuracy, it is generally necessary to set an additional fixed structure on the stamping platform to fix the workpiece, which makes the overall structure complicated and the operation cumbersome; and because the workpiece is a thin plate, local stamping can easily lead to problems such as deformation of the area surrounding the process hole, and the quality of the formed process hole is average.

[0051] The following is combined with Figures 1-8 Further explain the application plan.

[0052] First, refer to Figure 1 and Figure 2 The present application provides a punching mechanism having a first direction Z, and the punching mechanism includes a bracket 1, a driving member 2, a punching assembly 3 and a limiting assembly 4.

[0053] The bracket 1 includes a top plate 11, an intermediate plate 13, and a bottom plate 12, which are sequentially arranged along a first direction Z. Specifically, the thickness directions of the top plate 11 and the bottom plate 12 are parallel to the first direction Z, and the top plate 11 and the bottom plate 12 are arranged facing each other in the first direction Z; the thickness direction of the intermediate plate 13 is perpendicular to the first direction Z, and the intermediate plate 13 is arranged between the top plate 11 and the bottom plate 12. The top and bottom ends of the intermediate plate 13 are fixedly connected to the top plate 11 and the bottom plate 12, respectively, and can be bolted to facilitate modular assembly and disassembly, processing, and maintenance.

[0054] The driving member 2 is arranged on the support 1, and the driving member 2 has a moving part 20 reciprocating along the first direction Z. Specifically, the driving member 2 is arranged as a cylinder, and the driving member 2 is fixedly arranged on the side of the top plate 11 away from the bottom plate 12, the piston rod of the driving member 2 penetrates the top plate 11 and points to the bottom plate 12, and the moving part 20 is fixedly connected to the piston rod of the driving member 2.

[0055] With reference to Figure 2 and Figure 3 , the punching assembly 3 includes a base 31 and a punch 32 arranged on the base 31, and the punching assembly 3 is fixedly arranged on the moving part 20. Specifically, the base 31 is arranged in a block shape, and the punch 32 is arranged in a long rod shape and extends along the first direction Z. The moving part 20 is arranged in a block shape, the top end of the moving part 20 is fixedly connected to the end of the piston rod of the driving member 2, and the bottom end of the moving part 20 is detachably connected to the base 31. Specifically, the surface of the base 31 is provided with a connecting block 15 arranged in a T shape, and the moving part 20 is provided with a clamping groove matched with the clamping of the connecting block 15. Moreover, the connecting block 15 is bolted on the base 31 to achieve detachable connection, further realizing the design idea of overall modular disassembly. Above all, the driving member 2 drives the moving part 20 to reciprocate along the first direction Z, thereby driving the punching assembly 3 to reciprocate along the first direction Z, thereby realizing the punching process of the workpiece.

[0056] With reference to Figure 2 and Figure 4 , the limiting assembly 4 is arranged on the base 31, and the limiting assembly 4 includes a limiting member 41 and an elastic member 42. The limiting member 41 is slidably arranged outside the punch 32 along the first direction Z, and the elastic member 42 is arranged between the limiting member 41 and the base 31 along the first direction Z. The punch 32 has a punching surface 320 away from the base 31, wherein, in the natural state of the elastic member 42, the limiting member 41 is partially located on the side of the punching surface 320 away from the base 31, and in the compressed state of the elastic member 42, the limiting member 41 is located on the side of the punching surface 320 close to the base 31.

[0057] Wherein, in the natural state of the elastic member 42, the limiting member 41 is partially located on the side of the punching surface 320 away from the base 31, which means that, in the natural state of the elastic member 42, the limiting member 41 is closer to the workpiece than the punch 32, which makes the limiting member 41 contact the workpiece first, thereby providing a predetermined pressing force to fix the workpiece in advance; in the compressed state of the elastic member 42, the limiting member 41 is located on the side of the punching surface 320 close to the base 31, which means that the punch 32 can be lowered further than the limiting member 41, thereby performing the punching process on the workpiece.

[0058] The stamping process is as follows: the workpiece is placed flat on the surface of the bottom plate 12, the driving member 2 drives the stamping assembly 3 to move along the first direction Z towards the workpiece, the limiting assembly 4 moves together with the base 31, and then the limiting member 41 first contacts the workpiece. As the driving member 2 drives the base 31 to continue to move, the base 31 compresses the elastic member 42 to tightly press the limiting member 41 against the workpiece, thereby achieving the preliminary fixation of the workpiece by the limiting assembly 4. Then the driving member 2 drives the punch 32 to continue to move until the punch 32 punches a process hole on the workpiece. In the scheme of the embodiment of the application, the workpiece is preliminarily fixed by the limiting assembly 4 before the punch 32 contacts the workpiece, which ensures the stability of the workpiece and improves the accuracy of the punching process. Moreover, since the limiting member 41 is sleeved outside the punch 32, the position of the limiting member 41 is near the area to be punched, which realizes more accurate compression and shaping, thereby reducing the deformation of the workpiece in the area to be punched and further improving the accuracy of the punching process.

[0059] With reference to Figure 2 and Figure 4 , the base 31 is provided in a block shape, and the punch 32 is provided in a long rod shape and extends along the first direction Z. As an optional embodiment of the application, the base 31 is provided with a mounting hole 310 extending along the first direction Z and penetrating through, and the punch 32 is inserted and mounted in the mounting hole 310. The outer wall of the punch 32 is provided with a fastening groove 71, and the base 31 is provided with a fastening screw 72 in threaded cooperation, and one end of the fastening screw 72 is inserted and cooperated with the fastening groove 71. Through the design of the fastening groove 71 and the fastening screw 72, the punch 32 and the base 31 are detachably connected, which facilitates the maintenance and replacement of the punch 32. Moreover, this structure design is also convenient for installation and beneficial for the overall modular assembly design of the punching mechanism.

[0060] As an optional embodiment of the present application, a fixing member 5 is fixedly arranged on the base 31; wherein the outer wall of the limiting member 41 has a protruding portion 61, and the fixing member 5 has a stop portion 62, which is arranged on the side of the protruding portion 61 away from the base 31 in the first direction Z; one end of the elastic member 42 abuts against the limiting member 41, and the other end of the elastic member 42 abuts against the base 31. In the above embodiment, the two ends of the elastic member 42 are not fixedly connected with the limiting member 41 and the base 31, which is beneficial to the disassembly and maintenance of the elastic member 42. However, when the first direction Z is from top to bottom, that is, the first direction Z is the direction of gravity, the above connection mode will cause the limiting member 41 to slide from the outer side of the pressure head 32 and contact the workpiece, which will cause inconvenience in operation. Therefore, the fixing sleeve is designed to limit the displacement of the limiting member 41 along the first direction Z. At this time, the elastic member 42 can be selected to abut against the limiting member 41 and the base 31 at the two ends, instead of being fixedly connected. At this time, the elastic member 42 only provides elastic force, reduces fatigue damage of the elastic member 42, and improves the service life.

[0061] With reference to Figure 2 And Figure 5 More specifically, the fixing member 5 is arranged in a sleeve shape, a through groove 50 extending along the first direction Z is formed in the fixing member 5, the stop portion 62 is protruded on the inner wall of the end of the through groove 50 away from the base 31, and the stop portion 62 is integrally connected with the fixing member 5; the limiting member 41 comprises a first sleeve 411 and a second sleeve 412 connected with each other along the first direction Z, the outer diameter of the first sleeve 411 is larger than that of the second sleeve 412, and the protruding portion 61 is formed by the first sleeve 411 protruding compared with the second sleeve 412; the first sleeve 411 is slidingly arranged in the through groove 50, and the second sleeve 412 is slidingly arranged in the inner side of the stop portion 62.

[0062] When the driving member 2 drives the stamping assembly 3 to move towards the workpiece, the limiting assembly 4 moves together with the base 31, the limiting member 41 first contacts the workpiece, and then the base 31 continues to move under the driving of the driving member 2, so that the base 31 compresses the elastic member 42 to abut the limiting member 41 against the workpiece. The above process realizes the preliminary fixing of the workpiece through the limiting assembly 4. Then, the driving member 2 drives the pressure head 32 to continue to move, until the pressure head 32 stamps out the process hole on the workpiece. The limiting member 41 slides in the through groove 50, so that the limiting member 41 is limited by the fixing member 5, which further improves the stability of the limiting member 41, thereby improving the reliability and accuracy of the fixing of the workpiece.

[0063] As an optional embodiment of the present application, the fixing member 5 is detachably connected to the base 31. Specifically, the fixing member 5 is provided with a fixing lug 51 at the top in the first direction Z, the fixing lug 51 is integrally connected with the fixing member 5, and the fixing lug 51 is bolted to the side surface of the base 31.

[0064] In the above solution, the fixing member 5 can be removed from the base 31, and the elastic member 42 and the limit member 41 can also be removed from the base 31, which facilitates modular assembly and disassembly of the components. In particular, after a certain period of use, the elasticity of the elastic member 42 may be fatigued. In this case, the elastic member 42 can be easily replaced to ensure the accuracy of the pressing force on the workpiece. The pressure head 32 and the base 31 are also detachably connected, which makes the entire limit assembly 4 and the stamping assembly 3 removable and compatible, facilitating modular assembly and disassembly.

[0065] It should be noted that the connection structure between the limiting member 41 and the base 31 is not limited to the above structure. For example, in one example, referring to Figure 7 , one end of the elastic member 42 is fixedly connected to the base 31, and the other end of the elastic member 42 is fixedly connected to the limit member 41. A specific structure for the connection between the limit member and the base 31 is proposed, in which the limit member 41 is fixedly connected to the base 31 through the elastic member 42. The elastic member 42 not only provides an elastic force in the first direction Z so that the limit member 41 moves elastically in the first direction Z, but also the elastic member 42 connects the limit member 41 to the base 31, thereby ensuring that the base 31 can drive the limit member 41 away from the workpiece when it is away from the workpiece. It can be understood that in this embodiment, the elastic member 42 connects the limit member 41 to the base 31, and limits the position of the limit member 41 along the first direction Z. For example, when the first direction Z is the direction of gravity, the elastic member 42 prevents the limit member 41 from completely detaching from the outside of the pressure head 32. In this embodiment, the shape of the limit member 41 is not limited.

[0066] Back to Figure 2 and Figure 5 As an optional embodiment of the present application, an air duct 321 is provided in the pressure head 32, one end of the air duct 321 passes through the stamping surface 320 and is connected to the outside world, and the other end of the air duct 321 is connected to the air inlet connector. Specifically, a channel is also opened on the connecting block 15 to connect with the air duct 321, and the air inlet connector is connected to the connecting block 15. In implementing the above technical solution, impurities such as debris may be generated during the stamping process, affecting the product quality. The provision of the air duct 321 can spray air at the area of ​​the stamping hole, thereby removing impurities in a timely and rapid manner, thereby improving product quality. At the same time, it provides a more convenient assembly structure, which is convenient for modular installation.

[0067] Back to Figure 2 and Figure 3As an optional embodiment of the present application, the support 1 has opposite top plate 11 and bottom plate 12 in the first direction Z, and the guide assembly 8 is arranged between the bottom plate 12 and the base 31. The guide assembly 8 includes a guide sleeve 81 arranged on the base 31, a guide rod 82 arranged on the bottom plate 12, and a buffer 83 sleeved on the outer wall of the guide rod 82. The guide sleeve 81 and the guide rod 82 are in sliding sleeve fitting. The above technical solution can provide accurate limiting and guiding effect for the base 31, so that the punching position is more accurate, and the quality of the punched hole is ensured. It should be noted that two guide rods 82 are used in the embodiment of the present application, which can further improve the accuracy of the movement of the base, so that the punching is more accurate. The guide rod 82 is a hexagonal fixed screw rod, that is, the cross section of the guide rod 82 is hexagonal, which has higher accuracy when sliding with the guide sleeve 81. The buffer 83 is designed as a spring to improve the accuracy of punching.

[0068] With reference to Figure 1 and Figure 6 As an optional embodiment of the present application, the support 1 has opposite top plate 11 and bottom plate 12 in the first direction Z, and the guide assembly 8 is arranged between the bottom plate 12 and the base 31. The guide assembly 8 includes a guide sleeve 81 arranged on the base 31, a guide rod 82 arranged on the bottom plate 12, and a buffer 83 sleeved on the outer wall of the guide rod 82. The guide sleeve 81 and the guide rod 82 are in sliding sleeve fitting. The above technical solution can provide accurate limiting and guiding effect for the base 31, so that the punching position is more accurate, and the quality of the punched hole is ensured. It should be noted that two guide rods 82 are used in the embodiment of the present application, which can further improve the accuracy of the movement of the base, so that the punching is more accurate. The guide rod 82 is a hexagonal fixed screw rod, that is, the cross section of the guide rod 82 is hexagonal, which has higher accuracy when sliding with the guide sleeve 81. The buffer 83 is designed as a spring to improve the accuracy of punching.

[0069] In addition, the blanking hole 1000 is also designed in a certain structure. For example, in one example macro, a hole extending along the first direction Z and penetrating through is formed on the bottom plate 12, and a blanking die 10 is embedded in the hole. The blanking hole 1000 is formed in the blanking die 10 and penetrates through along the first direction Z. In the first direction Z, the diameter of the blanking hole 1000 gradually expands from the direction of the collecting sleeve 91 to the collecting bag 92, so as to facilitate the smooth flow of the waste, which is then collected by the waste collecting assembly 9.

[0071] The punching device can realize displacement in each direction of the spatial position, so as to better adapt to the punching operation of the workpiece. Moreover, due to the overall modular assembly design of the punching mechanism, the maintenance can be facilitated. In some optional scenarios, the pressure head can be disassembled and replaced by a die-cutting or other process machining module, so as to realize multi-scene application.

[0072] The above is only some of the embodiments of the present application, and does not limit the application in any form.
