[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] like Figure 1 to Figure 14 As shown, it shows an integrated trimming and punching device for electric hardware in one embodiment of the present disclosure, comprising: a fuselage 1 is placed on the ground; a trimming punch 2 is lifted and arranged on the fuselage 1; a punching punch 3 is lifted and arranged on the fuselage 1, and is located on one side of the trimming punch 2; a trimming and blanking table 4 is arranged on the fuselage 1, and is located below the trimming punch 2; a punching lower die 5 is arranged on the fuselage 1, and is located on one side of the trimming and blanking table 4 and below the punching punch 3; a pusher 6 is movably arranged on the fuselage 1, and the moving direction of the pusher 6 is perpendicular to the lifting direction of the trimming punch 2, and the pusher 6 is used to push the electric hardware 7 on the trimming and blanking table 4 onto the punching lower die 5.

[0026] In some examples, in order to solve the technical problem in the related technology that trimming and punching are completed by different equipment, resulting in low production and processing efficiency, the trimming and punching processes are integrated into one, which reduces the process conversion time and the waiting time caused by the transfer, and greatly improves the processing efficiency; avoids the positioning deviation caused by the conversion of multiple processes, ensures the dimensional accuracy of the electrical fittings, and improves the product quality; reduces the number of equipment purchased, reduces the equipment maintenance cost and the floor space occupied, thereby effectively reducing the production cost of the enterprise.

[0027] For example, Figure 2 , 3 As shown, first, the electric hardware to be processed is placed on the trimming and blanking table 4. The fuselage 1 is stably placed on the ground to provide solid support for the entire equipment.

[0028] After starting the equipment, the trimming punch 2 descends to trim the electric hardware. After trimming is completed, the pusher 6 starts to move. The pusher 6 moves on the guide rail of the machine body 1 through a driving method such as an electric screw or a pneumatic push rod. Its moving direction is perpendicular to the lifting direction of the trimming punch 2, and accurately pushes the electric hardware 7 that has completed trimming on the trimming and blanking table 4 to the punching lower die 5.

[0029] When the electric fitting 7 is pushed to the designated position on the punching lower die 5, the punching punch 3 descends to punch the electric fitting. The whole processing process is continuous and orderly, and there is no need to transfer the electric fittings between different equipment, which greatly improves production efficiency.

[0030] like Figure 1 to Figure 14 As shown, it shows an integrated trimming and punching device for electric hardware in another embodiment of the present disclosure, further comprising: an upper trimming die 8 is arranged on the trimming punch 2; a lower trimming die 9 is arranged on the body 1, and is located between the trimming punch 2 and the trimming blanking table 4, a gap 10 is left between the lower trimming die 9 and the trimming blanking table 4, an end of the pusher 6 is located in the gap 10, the lower trimming die 9 has a positioning through hole 11, the positioning through hole 11 is connected to the gap 10, the positioning through hole 11 is used to position the electric hardware 7, the upper trimming die 8 and the lower trimming die 9 are used to cooperate in cutting off the flash of the electric hardware 7.

[0031] In some examples, through the cooperation of the trimming upper mold 8 and the trimming lower mold 9, and the precise positioning of the positioning through hole 11, the trimming size and shape of the electric hardware 7 can be ensured to be accurate and consistent, thereby improving the trimming quality; the design of the gap 10 facilitates the falling and collection of trimming waste, thereby avoiding the accumulation of waste that affects the processing progress; the pushing piece 6 can timely and accurately push the trimming-completed electric hardware 7 to the punching lower mold 5, thereby closely connecting the trimming and punching processes, thereby improving the continuity and efficiency of production; precise positioning and stable trimming process reduce the generation of waste due to trimming errors, thereby reducing production costs; the integrated mold design and automated pushing process reduce the difficulty of operation, reduce manual intervention, and improve production efficiency and safety.

[0032] For example, Figure 8 As shown, when the trimming and punching integrated device is used, the electric power fitting 7 to be processed is first placed at the positioning through hole 11 of the trimming lower mold 9. The size and shape of the positioning through hole 11 match the electric power fitting 7, and it can be accurately positioned.

[0033] Then, the trimming punch 2 descends, driving the trimming upper die 8 to press down together. The trimming upper die 8 cooperates with the trimming lower die 9 to cut off the flash of the power fitting 7. The waste generated during the cutting process falls through the gap 10 between the trimming lower die 9 and the trimming blanking table 4.

[0034] After the trimming operation is completed, the pusher 6 located in the gap 10 starts to move, pushes the trimmed power fitting 7 out of the positioning through hole 11, and pushes it smoothly along the gap 10 to the punching lower die 5, ready for the punching process.

[0035] like Figure 1 to Figure 14 As shown, it shows an integrated device for trimming and punching electric hardware in another embodiment of the present disclosure, further comprising: an upper punching die 12 is arranged on the punching punch 3, and is located above the lower punching die 5, and the lower punching die 5 has a gap 2 13, and the gap 2 13 is located on one side of the gap 10, and is used to receive the electric hardware 7 pushed from the trimming and blanking table 4.

[0036] In some examples, the cooperation between the punching upper die 12 and the punching lower die 5 can quickly and accurately complete the punching process and improve the punching efficiency; the gap 13 can accurately receive the electric hardware pushed from the trimming process to ensure the accuracy of the punching position; the trimming and punching processes are seamlessly connected through reasonable structural design, which reduces the time for intermediate adjustment and positioning and further improves production efficiency; this structural design can adapt to the processing of electric hardware of different specifications and shapes, and improves the versatility and flexibility of the equipment; accurate punching positioning and stable punching process help improve the punching quality and reduce the product failure rate caused by punching deviation. .

[0037] For example, Figure 8 , 9 As shown, when the trimming of the electric hardware is completed, the push piece 6 is pushed out from the positioning through hole 11 of the trimming lower die 9, and moves along the gap 10 to the gap 2 13 of the punching lower die 5. At this time, the punching punch 3 drives the punching upper die 12 to descend, and the punching upper die 12 cooperates with the punching lower die 5 to perform a punching operation on the electric hardware located at the gap 2 13.

[0038] During the whole process, various components work together to complete the trimming and punching processes in an orderly manner.

[0039] like Figure 1 to Figure 14 As shown, it shows an integrated device for trimming and punching electric hardware in another embodiment of the present disclosure, the punching lower die 5 also has an avoidance through hole 14, the avoidance through hole 14 is connected to the gap 2 13, the gap 2 13 has a waste discharge hole 15, the fuselage 1 has an inclined guide groove 16, the inclined guide groove 16 is located below the waste discharge hole 15 and is connected to it, the inclined guide groove 16 is used to guide the waste discharged from the waste discharge hole 15 to the outside of the fuselage 1.

[0040] In some examples, the avoidance through hole 14, the waste discharge hole 15 and the inclined guide groove 16 cooperate to realize the automatic discharge of waste, without the need for frequent manual cleaning, thereby improving production efficiency; timely discharge of waste can effectively avoid the accumulation of waste inside the equipment, keep the inside of the equipment clean, and reduce the impact of waste accumulation on processing accuracy; the automatic export of waste to the outside of the fuselage 1 helps to improve the working environment and reduce safety hazards; it avoids problems such as poor equipment operation and failure due to waste accumulation, thereby improving the stability and reliability of the equipment; it reduces the wear and damage to the equipment caused by waste residues, thereby reducing the maintenance cost of the equipment.

[0041] For example, Fig.10 As shown, when the punching upper die 12 and the punching lower die 5 perform a punching operation on the electrical fittings, the generated waste will fall into the gap 2 13 through the avoidance through hole 14 on the punching lower die 5. The waste in the gap 2 13 will fall into the waste discharge hole 15 under the action of gravity. The waste will fall from the waste discharge hole 15 to the inclined guide slot 16 of the fuselage 1. Since the inclined guide slot 16 has a certain inclination angle, the waste will automatically slide out of the fuselage 1 along the inclined guide slot 16 and be collected in the designated waste collection area.

[0042] In this way, during the entire punching process, the waste generated can be discharged from the equipment in a timely and orderly manner and will not accumulate inside the equipment, thus ensuring the continuity and stability of the processing.

[0043] like Figure 1 to Figure 14As shown, it shows an integrated device for trimming and punching electric hardware in another embodiment of the present disclosure, further comprising: a material guide plate 17 is arranged on the fuselage 1, located on one side of the gap 2 13, and the material guide plate 17 is used to guide out the punched electric hardware 7; a conveying device 18 is located on one side of the fuselage 1, and is used to receive and transport the electric hardware 7 guided out from the material guide plate 17.

[0044] In some examples, the cooperation of the guide plate 17 and the conveying device 18 realizes the automatic discharge of the electrical fittings after punching, reduces manual handling, and improves the degree of automation of production; the processed electrical fittings are quickly and smoothly discharged and transported, shortening the production cycle and improving the overall production efficiency; the bumps and damages to the products caused by manual handling are avoided, and the product quality is ensured; the space is reasonably used to make the connection between the equipment and the conveying device 18 more compact, which is convenient for the overall planning and layout of the production line; workers do not need to directly participate in the handling of products, which reduces labor intensity and improves working conditions.

[0045] For example, Figure 2 As shown, when the electric hardware completes the punching process at the gap 13 of the punching lower die 5, the guide plate 17 comes into play. The guide plate 17 is fixedly installed at an appropriate position of the fuselage 1, and its inclination angle and position are carefully designed. The electric hardware after punching slides down along the guide plate 17 by its own gravity, and the conveying device 18 located on one side of the fuselage 1 is in a ready state. The conveying device 18 can be in the form of a conveyor belt, a conveyor chain, etc. When the electric hardware slides down from the guide plate 17, it falls accurately on the conveying device 18, and the conveying device 18 is started to transport the electric hardware that has completed trimming and punching to the next process or a designated storage area for subsequent processing or packaging.

[0046] like Figure 1 to Figure 14 As shown, it shows an integrated device for trimming and punching electric hardware in another embodiment of the present disclosure, wherein the contour of the positioning through hole 11 is larger than the outer contour of the electric hardware 7 after trimming, and also includes: an avoidance hole 20 is provided on the trimming upper mold 8, and the contour of the avoidance hole 20 is the same as the contour of the positioning through hole 11, and a pusher 19 is lifted and arranged in the avoidance hole 20; one end of an elastic member 21 acts on the inner wall of the avoidance hole 20, and the other end acts on the pusher 19, for providing a force for the pusher 19 to move toward the positioning through hole 11; a limit member 22 is lifted and arranged in a gap 10, and the limit member 22 is used to limit the electric hardware 7 falling from the positioning through hole 11.

[0047] In some examples, the pusher 19 can automatically push the trimming-completed electrical fittings out of the positioning hole 11 under the action of the elastic member 21, thereby realizing automatic unloading and improving production efficiency; the special design of the positioning hole 11 and the limiting function of the limiting member 22 ensure the position accuracy of the electrical fittings during the unloading and transfer process, which is conducive to the smooth progress of subsequent processes; the automated unloading process reduces manual operation, reduces labor intensity and the possibility of human error; the coordinated work between the various components makes the unloading and transfer process after the trimming process is completed smoother, reducing pauses and waiting time in production; the design of the pusher 19 avoids the possibility that the electrical fittings may be stuck between the trimming upper mold 8 and the trimming lower mold 9 after trimming is completed, thereby protecting the mold and extending the service life of the mold.

[0048] For example, Figure 4 As shown, when the integrated equipment for trimming and punching electric hardware is in operation, before the trimming process begins, the electric hardware to be processed is placed at the positioning through hole 11, and the trimming punch 2 drives the trimming upper die 8 to press down to perform the trimming operation. After the trimming is completed, the pusher 19 extends from the avoidance hole 20 under the action of the elastic member 21, pushing the trimmed electric hardware to move downward. Since the contour of the positioning through hole 11 is larger than the outer contour of the electric hardware after trimming, the electric hardware can smoothly pass through the positioning through hole 11. During the falling process of the electric hardware, the limiter 22 set in the gap 10 plays a limiting role to ensure that the electric hardware accurately falls on the trimming blanking table 4. Subsequently, the pusher 6 pushes the electric hardware to the punching lower die 5 for the punching process.

[0049] like Figure 1 to Figure 14As shown, it shows an integrated device for trimming and punching electric hardware in another embodiment of the present disclosure, which also includes: a gap 10 has a receiving groove 23, a limiting member 22 is located in the receiving groove 23, the limiting member 22 has a convex edge 24, and the convex edge 24 is located directly below the positioning through hole 11, and also includes: a limiting column 25 is arranged on the limiting member 22, located in the receiving groove 23, the limiting column 25 has an extrusion surface 26 and a clamping surface 27; one end of the elastic member 28 acts on the inner wall of the receiving groove 23, and the other end acts on the extrusion surface 26, so as to provide a force for the limiting column 25 to move toward the positioning through hole 11; the clamping member 29 has an extrusion surface 30, and a groove 31 is provided on the side wall of the receiving groove 23, the clamping member 29 is movably arranged in the groove 31, and the moving direction of the clamping member 29 is parallel to the moving direction of the pushing member 6. After the limiting column 25 descends, the extrusion Surface 1 26 squeezes extrusion surface 2 30 so that the card 29 retracts and then pops out and is stuck on the clamping surface 1 27; one end of the elastic member 32 acts on the inner wall of the groove 1 31, and the other end acts on the card 29, which is used to provide a force for the card 29 to move toward the accommodating groove 1 23; the reset member 33 is lifted and arranged on the limit column 25, located above the clamping surface 1 27, and the reset member 33 has an extrusion surface 34 and an extrusion surface 4 35. After the card 29 is stuck on the clamping surface 1 27, the limit column 25 continues to descend, and the extrusion surface 34 squeezes the extrusion surface 2 30 so that the card 29 retracts and then pops out and abuts against the extrusion surface 4 35. The extrusion surface 4 35 squeezes the card 29 and retracts so that the limit column 25 moves toward the positioning through hole 11 and resets; one end of the elastic member 4 36 acts on the clamping surface 1 27, and the other end acts on the reset member 33, which is used to provide a force for the reset member 33 to move toward the clamping surface 1 27.

[0050] In some examples, through the coordinated action of components such as the limit piece 22, the limit column 25 and the clamp 29, the falling electrical hardware can be accurately limited to ensure its accurate position, which is beneficial to the subsequent pushing and punching process of the push piece 6; the cooperation of the reset piece 33 and the relevant elastic parts enables the limit column 25 to automatically reset after completing the limiting effect, prepare for the next limiting, and improve the working efficiency and stability of the equipment; it can adapt to electrical hardware of different sizes and weights, and ensure the reliability of the limiting effect through the adjustment of the elastic parts and the cooperation of the components; precise limiting helps to improve the processing accuracy of the electrical hardware in the process of trimming and punching, and reduce the scrap rate; the complex and sophisticated structural design ensures the stability and reliability of the limiting function, reduces the probability of equipment failure, and improves the overall performance of the equipment.

[0051] For example, Figure 6As shown, when the equipment is running, after the trimming process is completed, the electric hardware falls from the positioning through hole 11, and the limiting member 22 is initially located in the gap 10. When it is necessary to clean the debris accumulated in this part of the space of the gap 10, there is no need to manually remove the limiting member 22. It is only necessary to let the pushing member 19 press down the convex edge 24 of the limiting member 22 to push the limiting member 22 into the accommodating groove 23. At this time, the extrusion surface 26 of the limiting column 25 located at the bottom of the limiting member 22 will squeeze the extrusion surface 230 of the clamping member 29, and push the clamping member 29 back into the groove 31 until the extrusion surface 26 and the extrusion surface 230 are separated. The second surface 30 is stuck on the clamping surface 27 of the limiting column 25. At this time, the clamping piece 29 clamps the limiting piece 22, making it unable to reset. At this time, the gap 10 can be quickly cleaned. After the cleaning is completed, when the limit needs to be released, the pushing piece 19 continues to press down the convex edge 24 of the limiting piece 22, and the extrusion surface 230 of the clamping piece 29 contacts the extrusion surface 34 of the reset piece 33. The reset piece 33 pushes the clamping piece 29 back into the groove 31 again until the clamping piece 29 contacts the extrusion surface 435 of the reset piece 33. At this time, under the action of the elastic piece 28, the extrusion surface squeezes the clamping piece 29 back into the groove 31 again, contacts the limit, and the limiting column 25 is reset.

[0052] like Figure 1 to Figure 14 As shown, it shows an integrated device for trimming and punching electric hardware in another embodiment of the present disclosure, the lower punching die 5 has a second accommodating groove 37, and also includes: a second limiting member 38 is lifted and arranged in the second accommodating groove 37, located on one side of the waste discharge hole 15; a mounting plate 39 is arranged in the second accommodating groove 37, located below the second limiting member 38; a rotating member 40 is rotatably arranged on the mounting plate 39, the second limiting member 38 has a second groove 41, and a convex portion 42 is provided on the side wall of the second groove 41, the rotating member 40 extends into the second groove 41, and a spiral extrusion portion 43 is provided on the side wall of the rotating member 40, and the extrusion portion 43 rotates and squeezes the convex portion 42 to make the second limiting member 38 rise and fall; one end of the elastic member 44 acts on the mounting plate 39, and the other end acts on the second limiting member 38, located on the periphery of the rotating member 40, and the elastic member 44 is used to provide a force for resetting the second limiting member 38.

[0053] For example, Fig.10As shown, during the operation of the electric hardware trimming and punching integrated device, the second limiting member 38 can play a role in limiting the electric hardware 7. After the punching is completed, the electric hardware 7 needs to be sent to the guide plate 17. At this time, the second limiting member 38 will hinder the electric hardware 7. It is relatively cumbersome to remove the second limiting member 38. At this time, it is only necessary to start the rotation of the rotating member 40. The extrusion portion 43 of the rotating member 40 contacts the convex portion 42 on the side wall of the second groove 41 as it rotates. Since the extrusion portion 43 is spiral, it will squeeze the convex portion 42 during the rotation process, thereby pushing the second limiting member 38 to overcome the elastic force of the fifth elastic member 44 and move downward, completing the concealment of the second limiting member 38, and no longer hindering the electric hardware 7 from moving out of the second gap 13. After the electric hardware 7 is moved out, the rotating member 40 stops rotating. Under the action of the fifth elastic member 44, the second limiting member 38 is reset upward to continue to play a limiting role.

[0054] like Figure 1 to Figure 14 As shown, it shows an integrated device for trimming and punching electric hardware in another embodiment of the present disclosure, which also includes: a rack 45 is arranged on the punching upper mold 12; a transmission gear set 46 is arranged in the accommodating groove 37, and the rack 45 is meshed with the transmission gear set 46 after being raised and lowered; a worm 47 is arranged on the transmission gear set 46 and rotates accordingly; a worm wheel 48 is arranged on the rotating member 40 and meshes with the worm 47.

[0055] In some examples, through the cooperation of the rack 45, the transmission gear set 46, the worm 47 and the worm wheel 48, the lifting and lowering action of the punching upper mold 12 and the lifting and lowering action of the limit member 38 are linked, without the need for an additional power source and control system, thereby simplifying the equipment structure and improving the synchronization and accuracy of the control; utilizing the movement of the punching upper mold 12 to drive the action of the limit member 38 saves energy consumption and improves the operating efficiency of the equipment; reducing the errors and failure risks caused by independent driving components and improving the overall stability and reliability of the equipment; reducing additional driving devices and control systems and reducing the manufacturing cost and maintenance cost of the equipment.

[0056] For example, Figure 11-Figure 14 As shown, when the equipment is running, when the punching upper die 12 descends for punching, the rack 45 arranged on the punching upper die 12 also descends accordingly. After the rack 45 descends to a certain position, it meshes with the transmission gear set 46 in the accommodating groove 37, driving the transmission gear set 46 to rotate. The rotation of the transmission gear set 46 causes the worm 47 connected thereto to rotate, and the worm 47 in turn drives the worm wheel 48 meshing therewith to rotate. The worm wheel 48 is installed on the rotating member 40, thereby driving the rotating member 40 to rotate. The spiral extrusion portion 43 on the rotating member 40 squeezes the convex portion 42 on the side wall of the groove 41 on the limiting member 38, causing the limiting member 38 to rise and fall.

[0057] According to one aspect, at least one embodiment of the present disclosure provides a power fitting trimming and punching process, using a power fitting trimming and punching integrated device, further comprising the following steps: S1, loading: placing the electric fitting 7 to be processed at the positioning through hole 11 of the trimming lower mold 9, and using the positioning through hole 11 to accurately position the electric fitting 7; S2, trimming operation: start the trimming punch 2, so that it drives the trimming upper die 8 to move downward, and closely cooperates with the trimming lower die 9 to cut off the flash of the power fitting 7. After the trimming is completed, the trimming punch 2 drives the trimming upper die 8 to rise; S3, pushing: the pushing piece 1 6 is started to push the electric hardware 7 that has completed trimming on the trimming blanking table 4 into the gap 2 13 of the lower punching die 5 along the direction perpendicular to the lifting direction of the trimming punch 2; S4, punching operation: start the punching punch 3, drive the punching upper die 12 to move downward, cooperate with the punching lower die 5, and perform punching operation on the power fitting 7. After the punching is completed, the punching punch 3 drives the punching upper die 12 to rise; S5, waste discharge: the waste generated during the punching process is discharged to the outside of the fuselage 1 through the waste discharge hole 15 of the punching lower die 5 and the inclined guide groove 16 of the fuselage 1; S6, discharging: the guide plate 17 discharges the punched electrical fittings 7, and the conveying device 18 receives and transports the electrical fittings 7 discharged from the guide plate 17.

Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.
