[0001] The present application relates to the technical field of template punching, and in particular to a punching guide mechanism and a punching machine. Background Art

[0002] Aluminum templates usually need to be punched to form pin holes so that pins can pass through the pin holes to connect two adjacent aluminum templates. At present, the punching guide mechanism for punching is usually a linear guide, or a matching guide column and guide sleeve, or both of these punching guide mechanisms are used at the same time. Such punching guide mechanisms have large sliding friction resistance, resulting in a less smooth relative movement process. Summary of the invention

[0003] In view of this, it is necessary to provide a punching guide mechanism and a punching machine with small friction resistance and smooth relative movement.

[0004] An embodiment of the present application provides a punching guide mechanism, including a stamping plate and a plurality of guide plates. The stamping plate includes a stamping portion and two sliding portions, the stamping portion is used to connect with the punch, the two sliding portions are arranged on both sides of the stamping portion, the sliding portion has a first surface, a second surface and a third surface connected in sequence, the first surface and the third surface are arranged opposite to each other, the second surface is located on the side away from the stamping portion, the first surface is provided with a first lubrication groove, the second surface is provided with a second lubrication groove, and the third surface is provided with a third lubrication groove, the first lubrication groove, the second lubrication groove and the third lubrication groove are used to store grease. A plurality of guide plates are respectively arranged on the first surface, the second surface and the third surface, the grease in the first lubrication groove, the second lubrication groove and the third lubrication groove is used to lubricate the corresponding guide plates, and the plurality of guide plates cooperate with each other to guide the movement of the stamping plate.

[0005] In the punching guide mechanism of the above embodiment, since the guide plate is in plane contact with the surface of the sliding part, it requires lower processing precision and a simpler structure than the contact of the guide pin, guide sleeve and other curved surfaces. In addition, the guide plates are in contact with different surfaces respectively, which can limit the circumference of the sliding part so that the sliding part can move stably. The guide plate is then lubricated by the grease in the lubrication groove to reduce the friction resistance between the guide plate and the sliding part, thereby improving the smoothness of punching.

[0006] In at least one embodiment, the first lubrication groove, the second lubrication groove, and the third lubrication groove all have length directions that are parallel to each other, and the length directions are parallel to the sliding direction of the stamping plate.

[0007] In the punching guide mechanism of the above embodiment, the length direction of the lubrication groove is parallel to the sliding direction of the punching plate, which can increase the area of ​​grease lubrication of the guide plate and the sliding part, thereby further reducing the friction resistance between the guide plate and the sliding part.

[0008] In at least one embodiment, an oil injection channel is opened on the stamping plate, and the oil injection channel is connected to the first lubrication groove, the second lubrication groove and the third lubrication groove.

[0009] In the punching guide mechanism of the above embodiment, by injecting lubricating oil from the oil injection channel, the grease can flow into the lubrication groove along the oil injection channel, so that when adding grease, there is no need to remove the guide plate, which makes adding grease more convenient.

[0010] In at least one embodiment, the oil injection channel includes a first oil injection hole communicating with the first lubrication groove, a second oil injection hole communicating with the second lubrication groove, and a third oil injection hole communicating with the third lubrication groove.

[0013] In the punching guide mechanism of the above embodiment, the aperture of the first connecting part is equal to the groove width of the first lubrication groove, so that the grease in the first connecting part can smoothly enter the first lubrication groove. The aperture of the first oil injection part is larger than the first connecting part, and the injection of grease can be easier.

[0016] In at least one embodiment, the guide plate includes a fixed portion and a guiding portion, wherein the guiding portion is arranged on the fixed portion, and the guiding portion is used to contact with one of the first surface, the second surface and the third surface to guide the movement of the stamping plate, and the surface roughness of the guiding portion is smaller than the surface roughness of the fixed portion.

[0017] In the punching guide mechanism of the above embodiment, the guide plate includes two parts: a fixed part and a guide part. The surface roughness of the guide part is smaller than that of the fixed part, so that the friction resistance between the guide part and the sliding part is small, and the entire guide plate does not need to be processed, which can reduce the processing cost.

[0018] In at least one embodiment, the guide portion is made of high-strength brass and graphite.

[0019] In the punching guide mechanism of the above embodiment, high-strength brass and graphite can effectively reduce the surface roughness of the guide part, so that the friction resistance between the guide part and the sliding part is low.

[0021] In the punching machine of the above embodiment, the driving mechanism drives the punching plate of the guide mechanism to slide, and the punching plate drives the punch to move under the guidance of the guide plate to stably punch the template.

[0022] In at least one embodiment, a plurality of adjusting parts are further included, wherein the adjusting parts include a first adjusting bolt and a second adjusting bolt, wherein the first adjusting bolt is passed through the fuselage and is threadedly connected to the guide plate, and the second adjusting bolt is threadedly connected to the fuselage and is supported on a side of the guide plate away from the stamping plate.

[0074] Some embodiments of the present application provide a punching guide mechanism, including a stamping plate and a plurality of guide plates. The stamping plate includes a stamping portion and two sliding portions, the stamping portion is used to connect with the punch, the two sliding portions are arranged on both sides of the stamping portion, the sliding portion has a first surface, a second surface and a third surface connected in sequence, the first surface and the third surface are arranged opposite to each other, the second surface is located on the side away from the stamping portion, the first surface is provided with a first lubrication groove, the second surface is provided with a second lubrication groove, and the third surface is provided with a third lubrication groove, the first lubrication groove, the second lubrication groove and the third lubrication groove are used to store grease. A plurality of guide plates are respectively arranged on the first surface, the second surface and the third surface, the grease in the first lubrication groove, the second lubrication groove and the third lubrication groove is used to lubricate the corresponding guide plates, and a plurality of guide plates cooperate with each other to guide the movement of the stamping plate.

[0075] In the punching guide mechanism of the above embodiment, since the guide plate is in plane contact with the surface of the sliding part, it requires lower processing precision and a simpler structure than the contact of the guide pin, guide sleeve and other curved surfaces. In addition, the guide plates are in contact with different surfaces respectively, which can limit the circumference of the sliding part so that the sliding part can move stably. The guide plate is then lubricated by the grease in the lubrication groove to reduce the friction resistance between the guide plate and the sliding part, thereby improving the smoothness of punching.

[0076] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0077] In order to more clearly describe the technical solutions of the embodiments of the present application, Figure 1 and Figure 2 The coordinate system is established in the following, and the subsequent description of the various positions of the punching machine is based on this coordinate system. Figure 1 and Figure 2 , the X-axis is the first direction, and the stamping plate can slide along the first direction. The Y-axis is the second direction, and the first direction is perpendicular to the second direction in the horizontal plane. The Z-axis is the third direction, and the third direction is perpendicular to the plane formed by the first direction and the second direction. In the description of this application, the terms "above", "below", "upward", and "downward" are all relative to the third direction.

[0078] See also Figure 1 and Figure 2In some embodiments, a punching machine 100 is provided, including a body 10, a driving mechanism 20 and a punching guide mechanism 40. The driving mechanism 20 and the punching guide mechanism 40 are both arranged on the body 10. The punching guide mechanism 40 includes a punching plate 42 slidably arranged on the body 10 and a plurality of punches 41 arranged on the punching plate 42. The driving mechanism 20 is used to drive the punching plate 42 so that the punches 41 on the punching plate 42 punch the template 200.

[0079] The following mainly introduces the structure of the driving mechanism 20 and the connection of the driving mechanism 20. Figure 1 is a three-dimensional diagram of the overall structure of the punching machine 100. Figure 2 is a top view of the punching machine 100 and the template 200, Figures 3 to 5 1 and 2 are top views of the driving mechanism 20, the punching guide mechanism 40 and the body 10 in different embodiments.

[0080] See also Figure 3 The driving mechanism 20 includes a driving member 21, a first transmission member 22 and a first pushing member 23. The driving member 21 is disposed on the body 10. The first transmission member 22 is rotatably connected to the body 10, and one end of the first transmission member 22 is connected to the driving member 21. The other end of the first transmission member 22 is connected to the first pushing member 23. The first pushing member 23 is also connected to the punching plate 42. The driving member 21 drives the first transmission member 22 to rotate, so that the first pushing member 23 moves with the first transmission member 22, and drives the punching plate 42 to slide along the first direction X, so that the punch 41 approaches and punches the template 200, or moves away from the template 200.

[0081] The first transmission member 22 is set to rotate around the first rotation point 201, the connection position between the driving member 21 and the first transmission member 22 is the driving point 202, the connection position between the first transmission member 22 and the first pushing member 23 is the first pushing point 203, the distance between the first rotation point 201 and the driving point 202 is the first distance L1, the distance between the second rotation point 206 and the second connecting member 25 is the second distance L2, and the first distance L1 is greater than the second distance L2.

[0082] Since the torque on the first transmission member 22 is equal and the first distance L1 is greater than the second distance L2, the first transmission member 22 can amplify the driving force generated by the driving member 21, that is, the force of the first transmission member 22 on the first push member 23 is greater than the force generated by the driving member 21 on the first transmission member 22. Therefore, the punch 41 on the punching plate 42 has a large punching force when punching the template 200, and the punching is more stable. Further, a larger number of punches 41 can be set on the punching plate 42, and the punch 41 can also stably punch the template 200 and reduce the number of times the template 200 is punched. Specifically, the number of punches 41 can be set to 23, and 23 pin holes can be generated by punching the template 200 once, while the number of punches 41 of the conventional punching machine 100 is only 8.

[0083] The following describes the connection between the driving member 21 and the body 10 , and the connection between the driving member 21 and the first transmission member 22 .

[0084] See also Figure 3 In some embodiments, one end of the driving member 21 is rotatably connected to the fuselage 10, and the other end is rotatably connected to the first transmission member 22. By extending and retracting the end of the driving member 21 close to the first transmission member 22, the first transmission member 22 can be driven to rotate. Optionally, the driving member 21 is a hydraulic cylinder, the cylinder body of the hydraulic cylinder is rotatably connected to the fuselage 10, and the piston rod of the hydraulic cylinder is rotatably connected to the first transmission member 22 through a U-shaped joint.

[0085] It is understandable that the way the driving member 21 connects the fuselage 10 and the first transmission member 22 is not limited to a rotational connection, and may be other ways. For example, one end of the driving member 21 is fixedly connected to the fuselage 10, and the other end is connected to the first transmission member 22 through a guide groove and a guide block, the guide block can slide on the guide groove, the guide block is set on the driving member 21 or the fuselage 10, and the guide groove is set on the other. When the driving member 21 is extended or retracted, the guide block moves relative to the guide groove and drives the first transmission member 22 to rotate. Similarly, it can also be set that one end of the driving member 21 is connected to the fuselage 10 through the guide block and the guide groove, and the other end is fixedly connected to the first transmission member 22.

[0086] The positions of the first transmission member 22 and the driving point 202 , the first transmission member 22 and the first pushing point 203 are described below.

[0087] The first transmission member 22 is driven to rotate around the first rotation point 201 by the driving member 21, and the first pushing member 23 is used to drive the stamping plate 42 to slide along the first direction X during the rotation of the first transmission member 22. In addition, since the first distance L1 from the driving point 202 of the driving member 21 and the first transmission member 22 to the first rotation point 201 is greater than the second distance L2 from the first pushing point 203 of the first transmission member 22 and the first pushing member 23 to the first rotation point 201, the punching force of the stamping plate 42 to punch the template 200 is greater, and the punching process is more stable. Optionally, the size of the first distance L1 is 430 mm, and the length of the second distance L2 is 135 mm.

[0088] See also Figure 4 In some embodiments, in the same plane, the straight line where the first distance L1 is located coincides with the straight line where the second distance L2 is located, and the first transmission member 22 is a sheet metal member in the shape of a long rod.

[0089] Please refer to Figure 3In some embodiments, in the same plane, the straight line where the first distance L1 is located is perpendicular to the straight line where the second distance L2 is located, and the first transmission member 22 is a sheet metal member having a substantially triangular shape. Compared with the above-mentioned first distance L1 and second distance L2 being on the same straight line, the length of the first transmission member 22 can be reduced, thereby improving space utilization, and the strength of the first transmission member 22 can be improved, so as to stably drive the first push member 23 to move.

[0090] The first pushing member 23 is described below.

[0091] In some embodiments, one end of the first push piece 23 is rotatably connected to the first transmission member 22, and the other end is rotatably connected to the stamping plate 42. It is understandable that the connection method of the first push piece 23 with the first transmission member 22 and the stamping plate 42 is not limited to this, and can also be other. For example, the first push piece 23 is fixedly connected to the first transmission member 22, and the first push piece 23 is connected to the stamping plate 42 by a guide block, a guide groove, etc. It is understandable that when the first push piece 23 is connected to the first transmission member 22 by a guide block and a guide groove, the position of the first push point 203 is the position of the guide block, and is not fixed relative to the first transmission member 22.

[0092] See also Figure 5 In some embodiments, the driving mechanism 20 further includes a second transmission member 24, a connecting member 25 and a second pushing member 26. The second transmission member 24, the connecting member 25 and the second pushing member 26 are introduced below.

[0093] The connecting member 25 extends along a second direction Y perpendicular to the first direction X. One end of the connecting member 25 is rotatably connected to the first transmission member 22, and the connection position is the first connection point 204. The other end is connected to the second transmission member 24, and the connection position is the second connection point 205. The distance between the first connection point 204 and the first rotation point 201 is a third distance L3. Optionally, the connecting member 25 is a sheet metal member in the shape of a long rod. Optionally, the driving point 202, the first connection point 204 and the first rotation point 201 are located on the same straight line.

[0094] The second transmission member 24 and the first transmission member 22 are spaced apart along the second direction Y. The second transmission member 24 is connected to the fuselage 10 by rotation around the second rotation point 206. The distance between the second rotation point 206 and the second connection point 205 is the fourth distance L4. In order for the first transmission member 22 and the second transmission member 24 to rotate synchronously in the same direction, the third distance L3 is equal to the fourth distance L4.

[0095] The second pushing member 26 and the first transmission member 22 are spaced apart along the second direction Y, one end of the second pushing member 26 is connected to the second transmission member 24, and the connection position is the second pushing point 207, and the other end is connected to the stamping plate 42. In order to ensure that the first pushing member 23 and the second pushing member 26 can move synchronously, the first pushing member 23 and the second pushing member 26 have the same shape, and the distance between the second rotation point 206 and the second pushing point 207 is the fifth distance L5, the fifth distance L5 is the same as the second distance L2, and the straight line where the first pushing point 203 and the second pushing point 207 are located is parallel to the second direction Y.

[0096] In some embodiments, the third distance L3 is greater than the second distance L2 to increase the force applied by the second push member 26 to the punching plate 42. Optionally, the second distance L2 is 135 mm, and the third distance L3 is 225 mm.

[0097] In some embodiments, the second push member 26 is connected to the second transmission member 24 and the stamping plate 42 in the same manner as the first push member 23 is connected to the first transmission member 22 and the stamping plate 42. That is, when the two ends of the first push member 23 are rotatably connected to the first transmission member 22 and the stamping plate 42, the two ends of the second push member 26 are also rotatably connected to the second transmission member 24 and the stamping plate 42. When the first push member 23 is fixedly connected to the first transmission member 22, the second push member 26 is also fixedly connected to the second transmission member 24.

[0098] See also Figure 6 In some embodiments, in order to improve the motion stability of the driving mechanism 20, a crank pin 30 is provided at each connection position of the driving mechanism 20. Each connection position of the driving mechanism 20 specifically includes the position where the driving member 21 is rotatably connected to the fuselage 10, the driving point 202, the first rotation point 201, the first pushing point 203, the position where the first pushing member 23 is connected to the stamping plate 42, the first connection point 204, the second connection point 205, the second rotation point 206, the second pushing point 207, and the position where the second pushing member 26 is connected to the stamping plate 42. The crank pin 30 is fixed to the fuselage 10, and each component of the driving mechanism 20 rotates around the crank pin 30 at the corresponding position. The structure of the crank pin 30 is introduced below.

[0099] The crank pin 30 may be an integrally formed structure and fixed to the fuselage 10 by bolts, welding, etc. In some embodiments, each crank pin 30 includes a pin shaft portion 31 and a stop plate 32, the pin shaft portion 31 is inserted through the fuselage 10, and the components of the drive mechanism 20 rotate around the pin shaft portion 31 at the corresponding position. A protrusion structure is formed at the end of the pin shaft portion 31, the stop plate 32 is detachably fixed to the fuselage 10, and a groove structure is formed to cooperate with the protrusion structure, and the protrusion structure is arranged in the groove structure to prevent the pin shaft portion 31 from rotating. It is understandable that the protrusion structure can also be arranged on the stop plate 32, and the groove structure is arranged on the pin shaft portion 31.

[0100] In some embodiments, a lubrication channel 311 is provided on the pin shaft portion 31, and the lubrication channel 311 is a curved channel that passes through the end and the side wall of the pin shaft portion 31, respectively. Grease is injected from the opening of the lubrication channel 311 at the end of the pin shaft portion 31, and the grease can flow along the lubrication channel 311 to the drive mechanism 20 for lubrication. Optionally, the lubrication channel 311 also passes through a raised structure on the pin shaft portion 31. Optionally, the lubrication channel 311 includes a first hole opened from the end of the pin shaft portion 31 and a second hole opened from the side wall of the pin shaft portion 31, and the first hole is connected to the second hole. Optionally, a ferrule joint is provided at the opening of the lubrication channel 311 at the end of the pin shaft portion 31, which is used to block the opening of the lubrication channel 311 to reduce dust contamination of the lubrication channel 311.

[0101] The driving mechanism 20 can drive the punching plate 42 to move along the first direction X to punch the template 200 . The punching guide mechanism 40 is mainly introduced below.

[0102] See also Figure 7 The punching guide mechanism 40 includes a punching plate 42, a plurality of guide plates 43 and a plurality of punches 41. The punching plate 42 includes a punching portion 421 and two sliding portions 422. The plurality of punches 41 are arranged at intervals on the punching portion 421 along the second direction Y. The punching portion 421 is connected to the first abutting member and the second abutting member of the driving mechanism 20 so that the punching portion 421 can slide along the first direction X to drive the punch 41 to punch the template 200.

[0103] See also Figure 8, the punch 41 can be directly fixed on the stamping plate 42 to directly punch the template 200. In some embodiments, a plurality of placement grooves 4211 are provided on the stamping portion 421, and the placement grooves 4211 are arranged at intervals along the second direction Y, and each punch 41 is arranged on a placement groove 4211. A pad 80 is also arranged in the placement groove 4211, and the pad 80 abuts against the punch 41 so that the punch 41 is stably arranged in the placement groove 4211. Optionally, the size of the pad 80 along the first direction X has multiple specifications, and the pads 80 of different specifications are located in different placement grooves 4211, so that the ends of the multiple punches 41 away from the pad 80 are not in the same straight line. During the punching process, the punches 41 corresponding to the pads 80 of different specifications punch the template 200 successively, and at the same time, the punches 41 for punching the template 200 are reduced to reduce the punching force required for punching, and the punching process is more stable. Optionally, there are five sizes of the pad 80.

[0104] See also Figure 8 and Fig. 9 , two sliding parts 422 are arranged at opposite ends of the stamping part 421 along the second direction Y. The peripheral side of each sliding part 422 has a first surface 423, a second surface 424 and a third surface 425 connected to each other. The first surface 423 and the third surface 425 are arranged opposite to each other, and the second surface 424 is between the first surface 423 and the third surface 425 and is located on the side away from the stamping part 421. A first lubrication groove 46 is provided on the first surface 423, a second lubrication groove 47 is provided on the second surface 424, and a third lubrication groove 48 is provided on the third surface 425. The first lubrication groove 46, the second lubrication groove 47 and the third lubrication groove 48 can store grease. A plurality of guide plates 43 are fixed to the fuselage 10 and are respectively located on the first surface 423, the second surface 424 and the third surface 425, so that the grease on the first lubrication groove 46, the second lubrication groove 47 and the third lubrication groove 48 can lubricate the corresponding guide plate 43 to reduce the friction between the guide plate 43 and the sliding part 422. A plurality of guide plates 43 are disposed around the sliding portion 422 , so that the plurality of guide plates 43 cooperate with each other to guide the stamping plate 42 to move along the first direction X and to limit positions in the second direction Y and the third direction Z.

[0105] Optionally, each sliding portion 422 is provided with three guide plates 43, and each guide plate 43 is correspondingly provided on a surface of the sliding portion 422. It is understandable that the number of guide plates 43 is not limited thereto, and each sliding portion 422 may be provided with four or five guide plates 43, etc., and each surface of the sliding portion 422 may be provided with one or more guide plates 43.

[0106] The guide plate 43 is lubricated by the grease in the lubrication groove, which can reduce the friction between the guide plate 43 and the sliding part 422, and the sliding between the guide plate 43 and the sliding part 422 is smoother. In addition, the guide plate 43 and the sliding part 422 are in plane contact, which is lower than the curved surface contact between the guide column and the guide sleeve or the linear slide, and has a simpler structure.

[0107] In some embodiments, the first lubrication groove 46, the second lubrication groove 47 and the third lubrication groove 48 all have a length direction, and the length direction of the lubrication groove is parallel to the first direction X, that is, the sliding direction of the sliding portion 422 is parallel to the length direction of the lubrication groove. In order to increase the area of ​​the sliding portion 422 in contact with the grease in the sliding direction, thereby improving the lubrication effect. Optionally, the length direction of the lubrication groove is not limited to being parallel to the first direction X, and can also be inclined relative to the first direction X or parallel to the second direction Y, etc.

[0108] In some embodiments, the first surface 423 is further provided with a plurality of first connecting grooves 461, which are arranged at intervals along the first direction X, and the first connecting grooves 461 are connected to the first lubricating groove 46, and the grease in the first lubricating groove 46 can flow into the first connecting groove 461 to increase the contact area between the grease and the guide plate 43 on the first surface 423, thereby reducing the friction between the guide plate 43 on the first surface 423 and the sliding portion 422. Compared with increasing the contact area between the grease and the guide plate 43 by increasing the groove width of the first lubricating groove 46, the addition of the first connecting groove 461 can not only maintain the overall strength of the sliding portion 422, but also ensure that the width direction of the guide plate 43 is fully in contact with the grease without excessive grease causing waste. Optionally, the first connecting groove 461 has a length direction, and the length direction of the first connecting groove 461 is parallel to the second direction Y, so that the length direction of the first connecting groove 461 is perpendicular to the length direction of the first lubricating groove 46.

[0109] In some embodiments, a plurality of second communicating grooves 471 are formed on the second surface 424, and a plurality of third communicating grooves 481 are formed on the third surface 425, and the plurality of second communicating grooves 471 and the plurality of third communicating grooves 481 are arranged at intervals along the first direction X. Moreover, the first communicating groove 461, the second communicating groove 471, and the third communicating groove 481 have the same shape and corresponding positions.

[0110] See also Fig.10 In some embodiments, an oil injection channel 50 is opened on the stamping plate 42, and the oil injection channel 50 is connected to the first lubrication groove 46, the second lubrication groove 47 and the third lubrication groove 48. By injecting grease into the oil injection channel 50, the grease can flow into the lubrication groove. The method of adding grease is simple and there is no need to disassemble the guide plate 43.

[0111] Optionally, the oil injection channel 50 includes a first oil injection hole 51, a second oil injection hole 52 and a third oil injection hole 53, wherein the first oil injection hole 51 is connected to the first lubrication groove 46, the second oil injection hole 52 is connected to the second lubrication groove 47, and the third oil injection hole 53 is connected to the third lubrication groove 48. Thus, according to actual needs, grease can be injected into different oil injection holes to lubricate the guide plate 43 at the corresponding position. The orifices for injecting grease in the multiple oil injection holes are all opened on the stamping part 421 to reduce the interference of the guide plate 43 when injecting grease.

[0112] Optionally, the first oil injection hole 51 includes a first oil injection portion 511 and a first connecting portion 512. The opening of one end of the first oil injection portion 511 is located on the stamping portion 421, and the other end of the first oil injection portion 511 is connected to one end of the first connecting portion 512. The other end of the first connecting portion 512 is connected to the first lubrication groove 46. By injecting grease into the opening of the first oil injection portion 511, the grease can flow into the first lubrication groove 46 along the first oil injection portion 511 and the first connecting portion 512.

[0113] In some embodiments, the aperture of the first oil injection portion 511 is larger than the aperture of the first connecting portion 512, and the aperture of the first connecting portion 512 is equal to the slot width of the first lubrication slot 46. Since the aperture of the first oil injection portion 511 is larger, it is convenient to inject grease. Optionally, the first oil injection portion 511 can be a hole with a constant aperture, or a tapered hole with a gradually decreasing aperture.

[0114] Optionally, the second oil injection hole 52 includes a second oil injection portion 521 and a second connecting portion 522 communicating with the second oil injection portion 521, the opening of the second oil injection portion 521 is located on the stamping portion 421, and the second connecting portion 522 is connected to the second lubricating groove 47 at one end away from the second oil injection portion 521. The third oil injection hole 53 includes a third oil injection portion 531 and a third connecting portion 532 communicating with the third oil injection portion 531, the opening of the third oil injection portion 531 is located on the stamping portion 421, and the third connecting portion 532 is connected to the third lubricating groove 48 at one end away from the third oil injection portion 531. By injecting grease into the openings of different oil injection portions, the grease can flow into the corresponding lubricating groove to lubricate the guide plate 43 and reduce the friction between the guide plate 43 and the sliding portion 422.

[0115] See also Fig.11, the guide plate 43 may be an integral structure and directly contact the sliding portion 422. In some embodiments, the guide plate 43 includes a fixing portion 431 and a guide portion 432, and the guide portion 432 is fixed to a side close to the sliding portion 422. The guide portion 432 is used to contact the surface of the sliding portion 422 to guide the sliding portion 422 to slide along the first direction X. The surface roughness of the guide portion 432 is less than the surface roughness of the fixing portion 431, which can not only make the friction between the guide portion 432 and the sliding portion 422 smaller, but also the overall machining accuracy requirement of the guide plate 43 is not high.

[0116] In some embodiments, the guide portion 432 and the sliding portion 422 are both finely ground to reduce the surface roughness of both and reduce the friction therebetween.

[0117] In some embodiments, the material of the guide portion 432 includes high-strength brass and graphite, which can effectively reduce the surface roughness of the guide portion 432, and the material of the sliding portion 422 is a metal alloy. Since the material of the guide portion 432 includes graphite, the sliding portion 422 will rub against the guide portion 432 during movement, causing the graphite to wear. If the material of the guide portion 432 and the sliding portion 422 both include graphite, during long-term use, it is difficult to adjust the positional relationship between the sliding portion 422 and the guide portion 432 at both ends of the stamping portion 421 due to the wear of the guide portion 432 and the sliding portion 422, thereby affecting the guidance of the sliding portion 422 by the guide portion 432. However, if only the guide portion 432 includes graphite, the position of the worn guide portion 432 can be adjusted accordingly after the guide portion 432 is worn, so that the guide portion 432 can stably guide the sliding portion 422 to move.

[0118] Optionally, the guide portion 432 is detachably connected to the fixing portion 431 by a fastener, so that the guide portion 432 can be replaced with another guide portion 432 after being scrapped, without having to replace the entire guide plate 43, which is conducive to cost saving. Optionally, the fastener is a bolt.

[0119] In some embodiments, the punching machine 100 further includes a plurality of adjusting members 70, the adjusting members 70 including a first adjusting bolt 71 and a second adjusting bolt 72, the first adjusting bolt 71 being disposed through the body 10 and being threadedly connected to the fixing portion 431 of the guide plate 43. The second adjusting bolt 72 is threadedly connected to the body 10 and abuts against the fixing portion 431. The position between the guide plate 43 and the sliding portion 422 can be adjusted by rotating the first adjusting bolt 71, and the second adjusting bolt 72 abuts against the guide plate 43 to prevent the guide plate 43 from moving away from the sliding portion 422. Thus, the first adjusting bolt 71 and the second adjusting bolt 72 can be used to adjust the position of the guide plate 43 and keep the position of the guide plate 43 stable.

[0120] In summary, a punching machine 100 is provided in the embodiment of the present application, wherein a lubrication groove is provided on the sliding portion 422, so that the grease on the lubrication groove lubricates the guide portion 432 of the guide plate 43 to reduce the friction between the guide portion 432 and the sliding portion 422. The material of the guide portion 432 includes high-strength brass and graphite, which can further reduce the surface roughness of the guide portion 432, and then the position of the guide portion 432 is adjusted by the adjusting member 70, so that the guide portion 432 can stably guide the sliding portion 422 to move.

[0121] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
