In addition, in the description of the present application, it should be noted that the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0070] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication, it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0071] The following is a further description of the embodiments of the present application in conjunction with the accompanying drawings. Figure 1 , define the first direction as the X-axis direction, the second direction as the Z-axis direction, and the third direction as the Y-axis direction.

[0072] See also Figure 1 and Figure 2 The present application embodiment provides a material pulling mechanism 100, which is used in conjunction with a stamping mechanism 200 to feed materials to the stamping mechanism 200. Please refer to Figure 3 The material pulling mechanism 100 includes a base 10 , a material guiding plate 20 , a material pulling member 30 and a driving assembly 40 .

[0073] Specifically, the base 10 may be a plate-shaped structure, which may support the guide plate 20, the driving assembly 40, etc. more stably.

[0074] See also Figure 2 and Figure 4 The guide plate 20 is slidably disposed above the base 10 for carrying the material belt 2000 . The material belt 2000 is disposed on the guide plate 20 along the X-axis direction.

[0075] Please also read Figure 5 and Figure 6The material pulling member 30 is elastically arranged in the material guide plate 20 along the Z-axis direction. The material pulling member 30 is provided with an inserting portion 31, and the inserting portion 31 is used to insert the material belt 2000. The inserting portion 31 is provided with a first inclined surface 32, and the distance between the first inclined surface 32 and the material guide plate 20 along the X-axis direction gradually increases. It can be understood that the material guide plate 20 can be provided with a receiving groove 21 inside to accommodate the material pulling member 30, and a spring or the like can be arranged between the material pulling member 30 and the material guide plate 20 to elastically push the material pulling member 30 to move along the Z-axis direction.

[0076] In some other embodiments, the material pulling member 30 is provided with a limiting portion 33, and the limiting portion 33 protrudes from the body 34 of the material pulling member 30, so that when the material pulling member 30 moves along the Z-axis direction, the limiting portion 33 can abut against other structures to limit the moving distance of the material pulling member 30 in the Z-axis direction. The material pulling member 30 is provided with a bearing surface 35 near the plug-in portion 31, and the bearing surface 35 is parallel to the XY plane, and the area is larger than the cross-sectional area of ​​the plug-in portion 31 in the XY plane, and the bearing surface 35 is connected to the first inclined surface 32, so that when the plug-in portion 31 is plugged into the material belt 2000, the material belt 2000 can be supported by the bearing surface 35 to prevent the material belt 2000 from moving to the body 34 of the material pulling member 30, resulting in the material pulling member 30 being unable to move to the lower side of the material belt 2000 through the first inclined surface 32 when the material pulling member 30 moves in the opposite direction of the X-axis direction.

[0077] The driving component 40 is arranged on the base 10 and connected to the guide plate 20, and is used to drive the guide plate 20 to reciprocate in the X-axis direction. When the driving component 40 drives the guide plate 20 to move in the opposite direction of the X-axis direction, the plug-in portion 31 moves to the lower side of the material belt 2000 through the first inclined surface 32. When the driving component 40 drives the guide plate 20 to move in the X-axis direction, it drives the material belt 2000 to move in the X-axis direction through the pulling member 30.

[0078] For related technologies, see Figure 1 , Figure 3 and Figure 6When the punching mechanism 200 punches the material strip 2000, the desired product 2001 is formed on the material strip 2000, and the product 2001 is attached to the material strip 2000. In the subsequent punching operation, the product 2001 is punched out from the material strip 2000. When the punching mechanism 200 punches the material strip 2000, a punching hole 2002 and a side groove 2003 are formed on the material strip 2000. The plug-in portion 31 of the material drawing member 30 is inserted into the punching hole 2002 of the material strip 2000, and then the material drawing member 30 can be driven by the material guide plate 20 to pull the material strip 2000 to move. When the material drawing member 30 moves in the opposite direction of the X-axis direction, the plug-in portion 31 of the material drawing member 30 is guided by the first inclined surface 32 to move to the lower side of the material strip 2000 until the material drawing member 30 corresponds to the next punching hole 2002. The material drawing member 30 is inserted into the next punching hole 2002 under the action of elastic force, and the next material drawing can be performed. When the punching holes 2002 are formed in pairs on the material strip 2000, a pair of the material drawing members 30 can be provided to simultaneously insert into the paired punching holes 2002 to improve the stability when drawing materials.

[0079] When the material pulling mechanism 100 provided in the embodiment of the present application is used in conjunction with the stamping mechanism 200, the material pulling mechanism 100 is arranged on one side of the stamping mechanism 200, the material strip 2000 is placed on the material guide plate 20 after being stamped by the stamping mechanism 200, the plug-in portion 31 of the material pulling member 30 is inserted into the material strip 2000, and the driving component 40 drives the material guide plate 20 to move along the X-axis direction, thereby pulling the material strip 2000 to move, so as to feed the stamping mechanism 200, and the driving component 40 drives the material guide plate 20 to move along the X-axis direction. After the material guide plate 20 moves one step, the driving assembly 40 drives the material guide plate 20 to move in the opposite direction of the X-axis direction. At this time, the material pulling piece 30 moves in the opposite direction of the X-axis direction with the material guide plate 20, and the first inclined surface 32 of the plug-in portion 31 abuts the material belt 2000, thereby causing the material pulling piece 30 to gradually move to the lower side of the material belt 2000, until the material pulling piece 30 moves one step, and the material pulling piece 30 is inserted into the material belt 2000 again, and the driving assembly 40 can drive the material guide plate 20 to pull the material along the X-axis direction. The material pulling mechanism 100 of the present application, through the cooperation between the material guide plate 20, the material pulling piece 30 and the driving assembly 40, can accurately control the moving step of the material when used in conjunction with the stamping mechanism 200, reduce the probability of misalignment of the feeding, and improve production efficiency.

[0080] In some embodiments, see Figure 3 , Figure 5 and Figure 6, the material pulling mechanism 100 also includes a first adjustment component 50 and a pressure plate 60. The first adjustment component 50 includes a first floating member 51, the first floating member 51 is elastically connected to the material guide plate 20 along the Z-axis direction, and one end of the first floating member 51 away from the material guide plate 20 is arranged corresponding to the material pulling member 30, and is used to cooperate with the material pulling member 30 to clamp the material belt 2000. It can be understood that the first floating member 51 is arranged in the receiving groove 21 of the material guide plate 20, and the first floating member 51 can be connected to the material guide plate 20 by a spring. The first floating member 51 can be provided with a limit block 511, so that when the first floating member 51 moves along the Z-axis direction, the limit block 511 can abut against other structures to limit the first floating member 51. A protrusion 512 may be provided at one end of the first floating member 51 away from the material guide plate 20, and the protrusion 512 corresponds to the position of the pulling member 30, so that when the plug-in portion 31 of the pulling member 30 is inserted into the stamping hole 2002 of the material strip 2000, the protrusion 512 of the first floating member 51 may cooperate with the bearing surface 35 of the pulling member 30 to clamp the material strip 2000.

[0081] Please also read Figure 1 The pressing plate 60 is connected to the external stamping device and is arranged above the guide plate 20, and is used to abut against the first floating member 51 during stamping, thereby driving the material strip 2000 to move downward. The external stamping device can be the stamping mechanism 200 mentioned below. It can be understood that the stamping mechanism 200 includes an upper die 210 and a lower die 220. During stamping, the upper die 210 moves toward the lower die 220 to close the die, thereby stamping the material strip 2000. Before stamping, the material strip 2000 is mounted above the lower die 220. During stamping, the upper die 210 first contacts the material strip 2000, and then pushes the material strip 2000 to the lower die 220 to stamp the material strip 2000. Therefore, the first floating member 51 can elastically support the material strip 2000 that is moved out of the stamping mechanism 200, so that the material strip 2000 is always in the same plane, thereby avoiding the material strip 2000 from being misaligned during stamping or pulling. It can be understood that the pressure plate 60 is connected to the upper mold 210. When the upper mold 210 moves toward the lower mold 220 and then closes the mold, the pressure plate 60 moves synchronously with the upper mold 210 and then abuts against the first floating part 51, so that the first floating part 51 cooperates with the pulling part 30 to clamp the material strip 2000 and move synchronously with the pressure plate 60.

[0082] In some embodiments, see Figure 2 , Figure 5 and Figure 6The first adjustment component 50 also includes a sensor 52, which is disposed in the first floating member 51 and corresponds to the material pulling member 30, and is used to detect the material pulling member 30. The sensor 52 can be a proximity switch, and the sensor 52 can be disposed in the protrusion 512 of the first floating member 51, and corresponds to the position of the material pulling member 30, and is used to detect the position of the plug-in portion 31 of the material pulling member 30. The specific detection method is that when the plug-in portion 31 is inserted into the punching hole 2002 of the material belt 2000, the plug-in portion 31 protrudes upward from the material belt 2000, and at this time, the sensor 52 can identify the plug-in portion 31, and then determine that the plug-in portion 31 has been inserted into the material belt 2000, and the material can be pulled. After the driving assembly 40 drives the material guide plate 20 and the material pulling member 30 to move a step distance along the X-axis direction, it then drives the material guide plate 20 and the material pulling member 30 to move a step distance in the opposite direction of the X-axis direction. During this process, the plug-in portion 31 of the material pulling member 30 first moves to the lower side of the material belt 2000, until it moves to the next punching hole 2002, and then inserts into the punching hole 2002 and is recognized by the sensor 52, at which time the material can be pulled again. If the material pulling member 30 does not move to correspond to the next punching hole 2002 during this process, resulting in the plug-in portion 31 not being inserted into the punching hole 2002, the sensor 52 cannot sense the plug-in portion 31, the sensor 52 sends a signal, the driving assembly 40 stops moving, and the operator performs maintenance.

[0083] In some embodiments, see Figure 1 , Figure 7 and Figure 8 The material pulling mechanism 100 also includes a second adjustment component 70, which is arranged on the upper side of the base 10 and is arranged on the rear side of the first adjustment component 50 along the X-axis direction, that is, the second adjustment component 70 is arranged on the side close to the lower mold 220. The second adjustment component 70 includes a second floating member 71, and the material strip 2000 passes through the second floating member 71. The second floating member 71 is used to elastically support the material strip 2000 along the Z-axis direction. The second floating member 71 can be elastically connected to the base 10 through a spring. The pressing plate 60 abuts against the second floating member 71 during stamping, thereby driving the material strip 2000 supported by the second floating member 71 to move downward. The second floating member 71 includes a supporting portion 711 and a holding portion 712, and a gap is left between the supporting portion 711 and the holding portion 712, and the material strip 2000 passes through the gap. The support portion 711 is used to support the material strip 2000. It can be understood that when the support portion 711 supports the material strip 2000, the position of the material strip 2000 is located in the same plane as the position of the material strip 2000 supported by the material pulling member 30. When the mold is closed, the pressing plate 60 moves with the upper mold 210 and abuts against the first floating member 51 and the second floating member 71 at the same time, so as to synchronously push the first floating member 51 and the second floating member 71 to move, thereby making the entire material strip 2000 always in the same plane during stamping.

[0084] In some embodiments, see Figure 7 and Figure 8 The second adjustment assembly 70 further includes a stopper 72, which includes a connection end 721, a stopper end 722 and a second inclined surface 723. The connection end 721 is rotatably connected to the second floating member 71, the stopper end 722 is elastically connected to the second floating member 71 and abuts against the material strip 2000, and the second inclined surface 723 is disposed between the connection end 721 and the stopper end 722. When the material strip 2000 moves along the X-axis direction, the stopper 72 abuts against the second inclined surface 723 and then pushes the stopper end 722 to retract. The stopper 72 may be a sheet-like structure, and a spring may be disposed on the side of the stopper end 722 of the stopper 72 away from the material strip 2000, or a torsion spring may be disposed at the connection end 721 of the stopper 72, so that the stopper end 722 can elastically abut against the material strip 2000. The stop end 722 can be inserted into the side groove 2003 of the material belt 2000 to prevent the material belt 2000 from moving in the opposite direction of the X-axis direction. When the material belt 2000 moves in the X-axis direction, the material belt 2000 abuts against the second inclined surface 723 to retract the stop end 722 until the next side groove 2003 corresponds to the stop end 722, and the stop end 722 is inserted into the side groove 2003. At this time, the driving component 40 drives the guide plate 20 and the pulling member 30 to move in the opposite direction of the X-axis direction, and the material belt 2000 is clamped by the stop member 72, and the material belt 2000 will not move in the opposite direction of the X-axis direction.

[0085] In some embodiments, see Figure 4 and Figure 5 The first adjustment assembly 50 further includes a first adjustment seat 53, which is adjustably connected to the material guide plate 20 along the Y-axis direction, and the first floating member 51 is elastically arranged in the first adjustment seat 53. The first adjustment seat 53 is used to adjust the position of the material pulling member 30. It can be understood that the first adjustment seat 53 is arranged in the receiving groove 21 of the material guide plate 20 and can be adjusted along the Y-axis direction. The first adjustment seat 53 can be provided with a waist-shaped groove arranged along the Y-axis direction, and connected to the material guide plate 20 by bolts, etc., so that the position of the first adjustment seat 53 in the Y-axis direction can be adjusted, and then the position of the first floating member 51 and the material pulling member 30 in the Y-axis direction can be adjusted to adapt to the material strips 2000 of different widths, thereby improving the applicable range of the material pulling mechanism 100. It can be understood that two first adjustment seats 53 can be provided, and they are symmetrically arranged in the receiving groove 21 to support two first floating members 51 and two material pulling members 30.

[0086] Please also read Figure 7The second adjustment assembly 70 further includes a second adjustment seat 73, which is adjustably connected to the base 10 along the Y-axis direction, and a second floating member 71 is elastically arranged in the second adjustment seat 73, and the second adjustment seat 73 is used to adjust the position of the stopper 72. The second adjustment seat 73 may be provided with a waist-shaped groove arranged along the Y-axis direction, and connected to the base 10 by bolts, etc., so that the position of the second adjustment seat 73 in the Y-axis direction can be adjusted. The second floating member 71 is arranged in the second adjustment seat 73, and can be elastically connected to the second adjustment seat 73 by a spring, etc., to adjust the position of the second adjustment seat 73 in the Y-axis direction, that is, to synchronously adjust the positions of the second floating member 71 and the stopper 72 in the Y-axis direction, so that the second floating member 71 can support the material strips 2000 of different widths, and the stopper 72 can correspondingly clamp the material strips 2000 of different widths, so as to improve the use range of the material pulling mechanism 100. It can be understood that two second adjustment seats 73 can be provided, symmetrically arranged on both sides of the material belt 2000 to support the two second floating members 71, and then support both sides of the material belt 2000 to improve the support stability. One or two stoppers 72 can be provided. When only one side of the material belt 2000 is provided with a side groove 2003, one stopper 72 can be provided and arranged on the first floating member 51 corresponding to the side groove 2003. When both sides of the material belt 2000 are provided with side grooves 2003, one or two stoppers 72 can be provided.

[0087] In some embodiments, see Figure 4 and Figure 7 A slide groove 731 extending along the Y-axis direction is provided on one side of the second adjustment seat 73 close to the base 10, and a slide rail 12 matching the slide groove 731 is provided on the base 10. The slide groove 731 is used to cooperate with the slide rail 12 to limit the second adjustment seat 73. In this way, when adjusting the position of the second adjustment seat 73 in the Y-axis direction, the second adjustment seat 73 can be prevented from being offset in the X-axis direction, thereby improving the accuracy of adjusting the second adjustment seat 73.

[0088] In some embodiments, see Figure 1 A limiting column 11 extending along the X-axis direction is provided on the upper side of the base 10, and the guide plate 20 is sleeved on the limiting column 11 and can slide along the limiting column 11. The limiting column 11 is used to limit the position of the guide plate 20. In this way, the stability of the moving position of the guide plate 20 can be improved. In one embodiment, two limiting columns 11 can be provided to further improve the stability of the guide plate 20 when it moves.

[0089] In some embodiments, see Figure 1 and Fig. 9The driving assembly 40 includes a driving member 41, a transmission member 42, a linkage member 43 and a lead screw 44. The lead screw 44 is fixedly connected to the guide plate 20, and the linkage member 43 is threadedly connected to the lead screw 44. The driving member 41 is fixedly connected to the base 10. The output end of the driving member 41 is connected to the linkage member 43 through the transmission member 42. The driving member 41 is used to drive the linkage member 43 to rotate through the transmission member 42, and then drive the lead screw 44 to move to drive the guide plate 20 to move. The driving member 41 can be a rotary cylinder, a stepping motor, etc., the output end of the driving member 41 can be connected to a gear, etc., the transmission member 42 can be an internal toothed belt, a transmission chain, etc., the linkage member 43 can be a gear, etc., and the linkage member 43 is provided with an internal thread inside, and the lead screw 44 is provided with an internal thread that matches the linkage member 43. The driving member 41 drives the linkage member 43 to rotate clockwise or counterclockwise through the transmission member 42 to guide the lead screw 44 to move along the X-axis direction or the opposite direction of the X-axis direction, thereby driving the guide plate 20 to move along the X-axis direction or the opposite direction of the X-axis direction. It can be understood that the driving assembly 40 can adjust the rotation speed of the driving member 41, thereby adjusting the reciprocating speed of the lead screw 44, thereby adapting the speed of the stamping mechanism 200 when stamping different material strips 2000, and has strong applicability.

[0090] The working process of the material pulling mechanism 100 provided in the embodiment of the present application is roughly as follows:

[0091] First, the material strip 2000 can be preliminarily punched, and the punched material strip 2000 has a punching hole 2002 and a side wall groove, and then the material strip 2000 is moved toward the material pulling mechanism 100, so that the material strip 2000 passes through the second floating member 71 of the second adjustment assembly 70 and the first floating member 51 of the first adjustment assembly 50, and the material is inserted into the punching hole 2002, so that the stopper 72 abuts against the side groove 2003. The first floating member 51 and the second floating member 71 support the material strip 2000 so that the part of the material strip 2000 and the part of the material strip 2000 located in the punching mechanism 200 are located in the same plane to prevent the material strip 2000 from bending.

[0092] Then the stamping mechanism 200 performs stamping, during which the upper die 210 and the lower die 220 are closed, the upper die 210 abuts against the material strip 2000 and moves downward for stamping, and at the same time, the pressing plate 60 synchronously abuts against the first floating member 51 and the second floating member 71 as the upper die 210 moves, thereby driving the material strip 2000 to move downward synchronously, so that the material strip 2000 is always in the same plane. After the stamping is completed, the upper die 210 moves away from the lower die 220, and the pressing plate 60 synchronously moves away from the first floating member 51 and the second floating member 71.

[0093] Then the driving member 41 drives the lead screw 44 to move along the X-axis direction through the transmission member 42 and the linkage member 43, thereby driving the guide plate 20 to move along the X-axis direction, the guide plate 20 drives the first adjustment seat 53, the first floating member 51 and the material pulling member 30 to move along the X-axis direction, and the material pulling member 30 pulls the material belt 2000 to move along the X-axis direction to realize the material pulling function. At this time, the material belt 2000 located in the second floating member 71 pushes against the second inclined surface 723 of the stopper 72 to make the stopper 72 retract. After moving a step, the stopper 72 is inserted into the next side groove 2003 to clamp the material belt 2000 to prevent the material belt 2000 from moving in the opposite direction of the X-axis direction. At this time, the driving member 41 drives the lead screw 44 to move in the opposite direction of the X-axis direction, thereby driving the guide plate 20 to move in the opposite direction of the X-axis direction, and the guide plate 20 drives the first adjustment seat 53, the first floating member 51 and the material pulling member 30 to move in the opposite direction of the X-axis direction. At this time, the material pulling member 30 is gradually moved to the lower side of the material strip 2000 under the guidance of the first inclined surface 32 until it corresponds to the next punching hole 2002, and the plug-in portion 31 of the material pulling member 30 can be inserted into the next punching hole 2002. At this time, the sensor 52 works to detect whether the plug-in portion 31 is inserted into the punching hole 2002. If the plug-in portion 31 is inserted into the punching hole 2002, the next step of punching and material pulling can be carried out. If the plug-in portion 31 is not inserted into the punching hole 2002, it is necessary to check and adjust.

[0094] After the inserting portion 31 of the material drawing piece 30 is inserted into the punching hole 2002, the next punching and material drawing can be carried out, and the above-mentioned actions can be repeated continuously.

[0095] When the width of the punched material strip 2000 is changed, the positions of the first adjustment seat 53 and the second adjustment seat 73 in the Y-axis direction are adjusted, which is easy to operate and has strong applicability.

[0096] When the lengths of the products 2001 on the material strip 2000 in the X-axis direction are different, that is, the distances between adjacent punching holes 2002 and adjacent side grooves 2003 are different, the moving distance of the driving member 41 driving the lead screw 44 in a single time can be adjusted. The operation is simple, and the applicability of the material pulling mechanism 100 is further improved.

[0097] See also Figure 1 The embodiment of the present application also provides a stamping device 1000, which is used to stamp a material strip 2000. The stamping device 1000 includes a stamping mechanism 200 and a material pulling mechanism 100 as described in the above technical solution. The stamping mechanism 200 is used to stamp the material strip 2000, and the material pulling mechanism 100 is arranged on one side of the stamping mechanism 200. The material pulling mechanism 100 is used to pull the material strip 2000 to move so as to feed the stamping mechanism 200. Among them, Figure 1 The stamping mechanism 200 shown is for illustration only and is not intended to limit the embodiments of the present application.

[0098] In one embodiment, the stamping mechanism 200 includes an upper die 210 and a lower die 220 , the base 10 is connected to the lower die 220 , and the pressing plate 60 is connected to the upper die 210 .

[0099] When the above-mentioned stamping equipment 1000 is in use, the material pulling mechanism 100 is used in conjunction with the stamping mechanism 200. The material pulling mechanism 100 is arranged on one side of the stamping mechanism 200. The material strip 2000 is placed on the material guide plate 20 after being stamped by the stamping mechanism 200. The plug-in portion 31 of the material pulling member 30 is inserted into the material strip 2000. The driving component 40 drives the material guide plate 20 to move along the X-axis direction, thereby pulling the material strip 2000 to move, so as to feed the stamping mechanism 200. After the material plate 20 moves a step, the driving assembly 40 drives the material guide plate 20 to move in the opposite direction of the X-axis direction. At this time, the material pulling piece 30 moves in the opposite direction of the X-axis direction with the material guide plate 20, and the first inclined surface 32 of the plug-in portion 31 abuts the material belt 2000, so that the material pulling piece 30 gradually moves to the lower side of the material belt 2000, until the material pulling piece 30 moves a step, and the material pulling piece 30 is inserted into the material belt 2000 again, and the driving assembly 40 can drive the material guide plate 20 to pull the material along the X-axis direction. The stamping equipment 1000 of the present application, through the cooperation between the material guide plate 20, the material pulling piece 30 and the driving assembly 40 of the material pulling mechanism 100, the material pulling mechanism 100 can accurately control the moving step of the material when used in conjunction with the stamping mechanism 200, reduce the probability of misalignment of the feeding, and improve production efficiency.
