Description

Technical Field

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

[0002] The template usually needs to be punched with a pin hole so that the two templates can be connected by a pin. During the punching process of the template, due to the high pressure of the punch on the template, after the punch passes through the template, the remaining material of the template adheres to the punch and is difficult to fall off, thus affecting the subsequent punching of the template. Summary of the invention

[0003] In view of this, it is necessary to provide a punching device that can reduce the adhesion of excess material to the punch.

[0004] An embodiment of the present application provides a punching device, including a frame, a driving mechanism arranged on the frame, a plurality of punches connected to the driving mechanism, and an oil guide member. The plurality of punches are arranged at intervals along the first direction, and the driving mechanism is used to drive the punches to move along the second direction to punch the template. The oil guide member is located on one side of the driving mechanism, and the oil guide member is provided with a plurality of through holes penetrating the opposite sides and a plurality of oil guide holes, each of the oil guide holes is connected to one of the through holes, and the oil guide holes are used to add lubricating oil. The punch is slidably arranged in the through hole, and has a punching end for punching the template. When the punch is in the standby position, the oil guide hole is located above the punching end along the third direction, and the third direction is perpendicular to the first direction and the second direction.

[0005] In the punching device of the above embodiment, the lubricating oil can flow to the through hole through the oil guide hole and drip onto the punching end, thereby maintaining the lubricity of the punch, thereby reducing the situation where the residual material of the template adheres to the punch when the punch punches the template. In addition, part of the lubricating oil can flow to the hole wall of the through hole, which can reduce the friction between the punch and the through hole, making it easier for the driving mechanism to drive the punch to move.

[0006] In at least one embodiment, the oil guide member is further provided with an oil groove, which extends along the first direction and is connected to the plurality of oil guide holes.

[0007] In the punching device of the above embodiment, the lubricating oil is injected into the oil groove so that the lubricating oil can flow along the oil groove and flow into different oil guide holes respectively. It is not necessary to inject the lubricating oil into different oil guide holes respectively, thereby improving the oil injection efficiency.

[0008] In at least one embodiment, the oil tank includes a main path and a plurality of branch paths connected to the main path, the branch paths are located on one side of the main path, and each of the branch paths is connected to one of the oil guide holes.

[0009] In the punching device of the above embodiment, lubricating oil is introduced into the main path, and the lubricating oil can flow from the main path into the branch path and reach the oil guide hole. Since the branch path is located on one side of the main path, the lubricating oil flowing in the main path will flow into different branch paths respectively, so that the lubricating oil can flow into each branch path evenly.

[0010] In at least one embodiment, an annular hole is formed on the hole wall of the through hole, the annular hole is connected to the oil guide hole, and the annular hole coincides with the projection of the oil guide hole along the third direction.

[0011] In the punching device of the above embodiment, since the projections of the annular hole and the oil guide hole along the third direction coincide, part of the lubricating oil passing through the oil guide hole enters the annular groove, so that the annular groove can collect the lubricating oil, thereby reducing the occurrence of the lubricating oil flowing out of the through hole and contaminating the frame.

[0012] In at least one embodiment, the punch includes a mother punch, a sub-punch, a supporting member and a first elastic member. The mother punch is connected to the driving mechanism and is provided with a punch hole extending along the second direction and penetrating the mother punch. The sub-punch is arranged in the punch hole, and the blanking end is located in the sub-punch. The supporting member is connected to the mother punch. The first elastic member is arranged in the punch hole, and one end of the first elastic member is supported by the sub-punch, and the other end of the first elastic member is supported by the supporting member.

[0013] In the punching device of the above embodiment, the first elastic member can be compressed by the pressing of the supporting member and the sub-punch, so that the first elastic member can push the sub-punch out of the punch hole, so that the residual material adhering to the sub-punch is separated from the sub-punch. And because the sub-punch can slide relative to the punch hole, during the telescopic movement of the sub-punch, lubricating oil will be driven into the punch hole to reduce the friction between the sub-punch and the mother punch.

[0014] In at least one embodiment, a guide surface is provided at one end of the female punch away from the driving mechanism, and the guide surface is inclined relative to the axis of the female punch.

[0015] In the punching device of the above embodiment, the guide surface is inclined relative to the axis, which can reduce the contact area between the template and the female punch, thereby reducing the situation where excess material adheres to the female punch.

[0016] In at least one embodiment, the driving mechanism includes a driving member and a stamping plate, wherein the driving member is disposed on the frame, the stamping plate is slidably disposed on the frame and connected to the driving member, the punch is disposed on the stamping plate, and the driving member drives the stamping plate to move along the second direction.

[0017] In the punching device of the above embodiment, the driving member drives the punching plate to move along the second direction, so that the punching plate can drive the punch to extend and retract to punch the template.

[0018] In at least one embodiment, the frame is provided with a guide portion, the guide portion is provided with a die that cooperates with the punch, and the side plate of the template is provided between the guide portion and the oil guide member. The oil guide member is connected to the stamping plate and is used to move along the second direction so as to cooperate with the guide portion and press the opposite sides of the side plate of the template, and the punch can be inserted into the through hole to punch the template and extend into the die.

[0019] In the punching device of the above embodiment, the guide part can cooperate with the oil guide member to clamp the opposite sides of the template, and the punch cuts the template and extends into the die to separate the template from the punch in the die.

[0020] In at least one embodiment, a connecting member and a second elastic member are provided between the stamping plate and the oil guiding member, the connecting member is fixedly connected to one of the stamping plate or the oil guiding member, and is slidably connected to the other so that the stamping plate and the oil guiding member can move relative to each other, and one end of the second elastic member abuts against the stamping plate, and the other end abuts against the oil guiding member.

[0021] In the punching device of the above embodiment, the punching plate and the oil guide member can move relative to each other through the connecting member, and the oil guide member can stably abut against the template by compressing the second elastic member.

[0022] In at least one embodiment, it further includes a lubrication pump and an oil guide pipe, wherein the lubrication pump is located on one side of the frame, one end of the oil pipe is connected to the lubrication pump, and the other end is connected to the oil tank.

[0023] In the punching device of the above embodiment, the lubrication pump can extract lubrication oil at a regular time and make the lubrication oil flow through the oil guide pipe into the oil tank, so that the lubrication oil can be automatically added to the punch.

[0024] The punching equipment of the present application injects lubricating oil into the oil guide hole so that the lubricating oil drips onto the punching end, thereby maintaining the lubricity of the punch, so that after the punch punches the template, the remaining material of the template can be separated from the punch, thereby improving the punching quality.

[0087] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0088] Some embodiments of the present application provide a punching device, including a frame, a driving mechanism disposed on the frame, a plurality of punches connected to the driving mechanism, and an oil guide member. The plurality of punches are arranged at intervals along the first direction, and the driving mechanism is used to drive the punches to move along the second direction to punch the template. The oil guide member is located on one side of the driving mechanism, and the oil guide member is provided with a plurality of through holes penetrating the opposite sides and a plurality of oil guide holes, each of the oil guide holes is connected to one of the through holes, and the oil guide holes are used to add lubricating oil. The punch is slidably disposed in the through hole, and has a punching end for punching the template. When the punch is located in the standby position, the oil guide hole is located above the punching end along a third direction, and the third direction is perpendicular to the first direction and the second direction.

[0089] In the punching device of the above embodiment, the lubricating oil can flow to the through hole through the oil guide hole and drip onto the punching end, thereby maintaining the lubricity of the punch, thereby reducing the situation where the residual material of the template adheres to the punch when the punch punches the template. In addition, part of the lubricating oil can flow to the hole wall of the through hole, which can reduce the friction between the punch and the through hole, making it easier for the driving mechanism to drive the punch to move.

[0090] 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.

[0091] See also Figure 1 and Figure 2 In one embodiment, a punching device 100 is provided, and the punching device 100 includes a frame 10, a driving mechanism 50, a punch 40, and an oil guide 20. The driving mechanism 50 is disposed on the frame 10, and the number of the punches 40 is multiple and is arranged at intervals along the first direction X. The driving mechanism 50 is connected to the punch 40 and can drive the punch 40 to move along the second direction Y so that the punch 40 punches the template 200 (such as Figure 7 As shown), wherein the first direction X is perpendicular to the second direction Y.

[0092] See also Figure 2 and Figure 3 The oil guide member 20 is located on one side of the driving mechanism 50. The oil guide member 20 is provided with a plurality of through holes 22 extending along the second direction Y and penetrating the oil guide member 20. The plurality of through holes 22 are arranged at intervals along the first direction X, and each through hole 22 corresponds to a punch 40, and the punch 40 can be slidably penetrated through the through hole 22. The oil guide member 20 is also provided with a plurality of oil guide holes 21, which are arranged at intervals along the first direction X, extend along the third direction Z, and each oil guide hole 21 is connected to a through hole 22. The third direction Z is perpendicular to the first direction X and the second direction Y.

[0093] See also Figure 3 and Figure 4 The punch 40 has a cutting end 421, which is the end that contacts the template 200 when cutting the template 200. When the punch 40 is in the standby position, the oil guide hole 21 is located above the cutting end 421 along the third direction Z. By adding lubricating oil to the oil guide hole 21, the lubricating oil can drip to the cutting end 421 along the oil guide hole 21, so that after the cutting end 421 cuts the template 200, the residual material of the template 200 will be separated from the cutting end 421. The standby position of the punch 40 is the position where the punch 40 is in standby when the driving mechanism 50 drives the cutting end 421 to retract so that the cutting end 421 does not contact the template 200. The residual material is the material produced by the template 200 after the pin hole is formed in the cutting template 200.

[0094] Optionally, in some embodiments, an oil groove 23 is formed on the oil guide member 20, and the oil groove 23 extends along the first direction X, so that the oil groove 23 is connected with the plurality of oil guide holes 21. By adding lubricating oil to the oil groove 23, the lubricating oil can be introduced into the oil guide holes 21 along the oil groove 23.

[0095] The oil tank 23 includes a main channel 231 and a branch channel 232 (such as Figure 6 ), the number of the branch roads 232 is multiple and they are arranged at intervals along the first direction X, the branch roads 232 are located on one side of the main road 231 and are connected to the main road 231. Along the third direction Z, the branch roads 232 are located above the oil guide holes 21, and each branch road 232 is connected to an oil guide hole 21. The projections of the main road 231 and the oil guide holes 21 in the third direction Z do not overlap, and compared with the overlap of the projections, the lubricating oil can be more evenly distributed to each oil guide hole 21 along the main road 231.

[0096] Optionally, in some embodiments, an annular groove 25 is formed on the wall of the through hole 22, the annular groove 25 is connected to the oil guide hole 21, and the through hole 22 and the annular groove 25 overlap in the projection of the third direction Z. Part of the lubricating oil enters the annular groove 25 along the oil guide hole 21 and is collected, thereby reducing the lubricating oil from leaking out of the through hole 22 and contaminating the frame. When the driving mechanism 50 drives the punch 40 to extend along the second direction Y, the lubricating oil can reduce the friction between the punch 40 and the wall of the through hole 22.

[0097] Please refer to Figure 1 and Figure 2 Optionally, in some embodiments, the punching device 100 further includes a lubrication pump 30 and an oil pipe 31. The lubrication pump 30 is located on one side of the frame. One end of the oil pipe 31 is connected to the lubrication pump 30, and the other end is connected to the main channel 231. The lubrication pump 30 supplies lubricating oil to the main channel 231 through the oil pipe 31 at a regular time, so that the lubricating oil flows along the main channel 231, the branch channel 232, and the oil guide hole 21 in sequence, and falls on the blanking end 421 to maintain the lubricity of the punch 40.

[0098] Optionally, in some embodiments, a guide mechanism 60 is provided on the frame, and the guide mechanism 60 includes a guide plate 61 and a guide wheel 62. The guide plate 61 is fixed to the frame and has a fixing hole 611. Along the third direction Z, the fixing hole 611 is located above the main track 231, and the oil pipe 31 is passed through the fixing hole 611 to supply oil to the main track 231. The oil pipe 31 is positioned through the fixing hole 611 to keep the position of the oil pipe 31 stable. The guide wheel 62 is rotatably provided on the guide plate 61 to guide the template 200 to move along the first direction X.

[0099] Optionally, in some embodiments, a cylinder 63 is also fixed on the guide plate 61 . The cylinder 63 is located on one side of the guide wheel 62 and is used to cooperate with the frame to press against the opposite sides of the template 200 to fix the template 200 .

[0100] See also Figures 3 to 5 When the template 200 is fixed, the punch 40 punches the template 200. The punch 40 includes a mother punch 41, a sub-punch 42, a support member 44 and a first elastic member 43. The mother punch 41 is connected to the driving mechanism 50 and is provided with a punch hole 411. The punch hole 411 extends along the second direction Y and passes through the opposite ends of the mother punch 41. The support member 44, the first elastic member 43 and the sub-punch 42 are all arranged in the punch hole 411. The sub-punch 42 can slide along the punch hole 411, and the punching end 421 is located at the end of the sub-punch 42. The first elastic member 43 is located between the support member 44 and the sub-punch 42, and one end of the first elastic member 43 is supported by the support member 44 and the other end of the first elastic member 43 is supported by the sub-punch 42. The first elastic member 43 can be compressed by the abutment of the sub-punch 42 and the abutment member 44, so that the first elastic member 43 generates thrust and causes the punching end 421 of the sub-punch 42 to protrude out of the punch hole 411. Optionally, the first elastic member 43 is a spring.

[0101] When punching the template 200, the driving mechanism 50 drives the punch 40 to extend, and the punching end 421 of the sub-punch 42 first contacts the template 200 and temporarily keeps the position fixed, and the mother punch 41 continues to move toward the template 200, so that the sub-punch 42 compresses the first elastic member 43, and then the sub-punch 42 and the mother punch 41 punch the template 200 together. The residual material is separated from the template 200 and adheres to the punch 40, and the first elastic member 43 recovers and pushes the sub-punch 42 to extend, so as to push the residual material to separate from the punch 40. In addition, the lubricating oil drips on the punching end 421, and through the telescopic movement of the sub-punch 42 in the punch hole 411, the sub-punch 42 and the mother punch 41 can be lubricated to reduce the friction between the sub-punch 42 and the mother punch 41.

[0102] Optionally, in some embodiments, a guide surface 413 is provided at one end of the female punch 41 away from the driving mechanism 50, and the guide surface 413 is inclined relative to the axis of the female punch 41, so that the female punch 41 is formed into a truncated cone shape, which can reduce the contact area with the template 200 compared with the end of the female punch 41 being a plane, thereby reducing the situation where the residual material of the template 200 adheres to the female punch 41. It can be understood that the guide surface 413 can be a straight inclined surface to make the female punch 41 truncated cone shape, and the guide surface 413 can also be a curved surface to make the end of the female punch 41 hemispherical, etc.

[0103] Optionally, in some embodiments, the punch 40 further includes a protective cover 45 , which is connected to the driving mechanism 50 and is sleeved on the female punch 41 , so that the protective cover 45 and the female punch 41 can move together.

[0104] The driving mechanism 50 includes a driving member 51 and a punching plate 52. The driving member 51 is disposed on the frame 10. The punching plate 52 is connected to the driving member 51 and is slidably disposed on the frame 10. The driving member 51 can drive the punching plate 52 to move along the second direction Y. The punching plate 52 is provided with a first mounting hole. The protective cover 45 is installed in the first mounting hole so that the punch 40 as a whole can move with the punching plate 52. Optionally, the driving member 51 is a rotary hydraulic cylinder.

[0105] Optionally, in some embodiments, the stamping plate 52 is further provided with a second mounting hole, and the second mounting hole is located on the side of the punch 40 close to the driving member 51. A pressing assembly 70 is installed in the second mounting hole, and the pressing assembly 70 includes a fixing member 71, a pressing elastic member 72, and a pressing member 73. The fixing member 71 is fixed to the second mounting hole, one end of the pressing elastic member 72 is pressed against the fixing member 71, and the other end is pressed against the pressing member 73, the pressing member 73 is slidably arranged in the second mounting hole, and one end of the pressing member 73 away from the pressing elastic member 72 is pressed against the pressing member 44, so as to push the punch 40 to move along the second direction Y.

[0106] Optionally, in some embodiments, the frame 10 is provided with a guide portion 11, and the guide portion 11 and the driving mechanism 50 are located on opposite sides of the oil guide member 20. The template 200 includes a plate body 210 and side plates 220 disposed on both sides of the plate body 210. When punching the template 200, the side plates 220 are disposed between the guide portion 11 and the oil guide member 20, and the side plates 220 are punched by the punch 40 to form a pin hole in the side plates 220. The guide portion 11 is provided with a third mounting hole corresponding to the punch 40, and a die 46 is installed in the third mounting hole. After the sub-punch 42 and the mother punch 41 punch the side plate 220, they can extend into the die 46. At this time, the sub-punch 42 extends from the punch hole 411 of the mother punch 41 and pushes the residual material of the template 200 to separate the residual material from the sub-punch 42.

[0107] Optionally, in some embodiments, the oil guide member 20 is connected to the stamping plate 52, and the stamping plate 52 can drive the oil guide member 20 to move so that the oil guide member 20 can resist the side plate 220 of the template 200 and cooperate with the guide part 11 to press the opposite sides of the side plate 220.

[0108] Optionally, in some embodiments, a connecting member 24 and a second elastic member 80 are provided between the oil guide member 20 and the stamping plate 52, one end of the connecting member 24 is fixedly connected to the stamping plate 52, a guide hole extending along the second direction Y is provided on the oil guide member 20, and the other end of the connecting member 24 is slidably provided in the guide hole of the oil guide member 20, so that the stamping plate 52 and the oil guide member 20 can move relative to each other. One end of the second elastic member 80 abuts against the stamping plate 52, and the other end abuts against the oil guide member 20, so that the oil guide member 20 can more stably abut against the side plate 220 of the template 200. It is understandable that the connecting member 24 can also be fixedly connected to the oil guide member 20, and the guide hole is provided on the stamping plate 52, so that the connecting member 24 is slidably connected to the stamping plate 52.

[0109] See also Figure 7 Optionally, in some embodiments, the punching device 100 is a double-sided punching device 100, which can punch holes on both sides of the template 200 at the same time. The frames 10 are respectively a first frame 10a frame 10 and a second frame 10b frame 10. The first frame 10a frame 10 and the second frame 10b frame 10 are respectively provided with an oil guide 20, a punch 40, a guide mechanism 60 and a driving mechanism 50.
