Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a workpiece processing equipment. Background Technology

[0002] Currently, components such as levers inside circuit breakers on the market are made of sheet metal, which are generally manufactured through a multi-stage stamping process using stamping dies. In this technology, the actual production involves multiple sets of stamping dies, from rough to fine, equipped with punches of corresponding precision. The sheet metal or blank is sequentially passed through these dies for stamping, ultimately producing the desired workpiece. Firstly, the manufacturing cost of multiple sets of dies is high. Furthermore, the process involves multiple transfer steps between the sheet metal and the workpiece blank, requiring significant manpower and resources for coordination and operation, which increases production costs, reduces work efficiency, and lengthens the manufacturing cycle.

The blanking gap between the N sets of contour punches and the workpiece contour decreases progressively, and the contour of the blanking punch is identical to that of the workpiece, indicating that the material plate undergoes multiple blanking processes from rough to fine. Finally, the blanking punch performs the final blanking of the material plate to obtain a workpiece of the required size. This workpiece processing equipment performs multiple blanking processes from rough to fine, exhibiting strong functionality and integration. The material plate processing does not require the transfer of multiple sets of molds or the operation of any steps, saving manpower and resources, increasing processing efficiency, and effectively shortening the preparation cycle.

[0057] This embodiment provides a workpiece 4 processing device. (Refer to...) Figures 1 to 9 As shown, the workpiece 4 processing equipment includes a lower die mechanism 1 and an upper die mechanism 2. The lower die mechanism 1 includes a lower template 11, on which the material plate 3 is supported and conveyed along a first direction. The upper die mechanism 2 includes an upper template 21 positioned above the lower template 11. The upper template 21 can move up and down relative to the lower template 11. N sets of outer contour punches and one blanking punch 25 are sequentially arranged along the first direction on the end face of the upper template 21 facing the lower template 11, where N > 1. Along the conveying direction of the material plate 3, the material plate 3 is sequentially processed into workpiece 4 by the N sets of outer contour punches and the blanking punch 25. The blanking gap between the N sets of outer contour punches and the outer contour of the workpiece 4 decreases sequentially, and the outer contour of the blanking punch 25 is the same as the outer contour of the workpiece 4.

[0058] In this embodiment, the workpiece 4 processing equipment integrates N sets of contour punches with progressively increasing precision. During use, the material plate 3 is supported on the lower template 11 and conveyed along a first direction at a predetermined speed and step distance. In coordination with the conveying step distance, the upper template 21 descends and engages with the lower template 11 at a fixed frequency, thus performing fixed-frequency mold closing. During the conveying process, the material plate 3, corresponding to each part of the workpiece 4, sequentially passes through the N sets of contour punches and the blanking punch 25. The blanking gap between the N sets of contour punches and the contour of the workpiece 4 decreases progressively, indicating that the material plate 3 undergoes multiple blanking processes from rough to fine. Finally, the blanking punch 25 performs the final blanking of the material plate 3 to obtain the workpiece 4 of the required size. This workpiece processing equipment performs multiple blanking processes from rough to fine on the workpiece 4, exhibiting strong functionality and integration. During the processing of the material plate 3, there is no need to transfer multiple sets of molds or operate any steps, saving manpower and resources, resulting in high processing efficiency and effectively shortening the preparation cycle.

[0059] Specifically, in this embodiment, N=3, and along the conveying direction of the material plate 3, the three outer contour punch groups are respectively designated as the first outer contour punch group, the second outer contour punch group, and the third outer contour punch group. Wherein,

[0060] The material plate 3 is sequentially processed by the first outer contour punch group, the second outer contour punch group, the third outer contour punch group, and the blanking punch 25 to form the workpiece 4. The first outer contour punch group has a first blanking gap with the contour of the workpiece 4, which is 20%t-30%t; the second outer contour punch group has a second blanking gap with the contour of the workpiece 4, which is 5%t-7%t; and the third outer contour punch group has a third blanking gap with the contour of the workpiece 4, which is 0.5%t-1%t. The outer contour of the blanking punch 25 is the same as the outer contour of the workpiece 4.

[0061] As the material plate 3 is conveyed, each part corresponding to the workpiece 4 is sequentially punched by the first outer contour punch group, the second outer contour punch group, and the third outer contour punch group. The first outer contour punch group has a first punching gap of 20%t-30%t between itself and the contour of the workpiece 4; the second outer contour punch group has a second punching gap of 5%t-7%t; and the third outer contour punch group has a third punching gap of 0.5%t-1%t. The decreasing punching gaps during the punching process indicate that the material plate 3 undergoes multiple punching passes from rough to fine, culminating in the final punching by the blanking punch 25 to obtain the workpiece 4 of the required size.

[0062] In this embodiment, the first direction is specifically indicated as shown in the attached drawings. The first direction is preferably set as the length direction of the material plate 3, which is also the conveying direction of the material plate 3 on the lower template 11.

[0063] Optionally, the lower template 11 is provided with a conveying device specifically for conveying the material plate 3. The conveying device can be a conveyor belt.

[0064] Optionally, t can be the thickness of workpiece 4 or the single-sided gap of workpiece 4.

[0065] In this embodiment, the first outer contour punch group includes a first outer punch 221 and a first inner punch 222. The first outer punch 221 punches the material plate 3 to form a first outer contour blank surface 301 corresponding to the two opposite ends of the workpiece 4 in the second direction. The first inner punch 222 punches the material plate 3 to form a second outer contour blank surface 302 corresponding to the two opposite ends of the workpiece 4 along the first direction. Both the first outer contour blank surface 301 and the second outer contour blank surface 302 have a first punching gap with the workpiece 4. The second outer contour punch group includes a second outer punch 231 and a second inner punch 232. The second outer punch 231 punches the material plate 3 to form a third outer contour blank surface 303 corresponding to the two opposite ends of the workpiece 4 in the second direction. The second inner punch 232 punches the material plate 3 to form a fourth outer contour blank surface 304 corresponding to the two opposite ends of the workpiece 4 along the first direction. Both the third outer contour blank surface 303 and the fourth outer contour blank surface 304 have a second punching gap with the workpiece 4. The third outer contour punch group includes a third outer punch 241, which punches the material plate 3 to form a fifth outer contour blank surface 305 corresponding to the opposite ends of the workpiece 4 in the second direction. The fifth outer contour blank surface 305 and the workpiece 4 have a third punching gap.

[0066] In this embodiment, the second direction is specifically indicated as shown in the accompanying drawings, and the second direction is preferably set as the width direction of the material plate 3.

[0067] Specifically, the material plate 3 is divided into multiple punching areas along the first direction, and each punching area corresponds to a workpiece 4 that can be ultimately processed. To more clearly describe the processing, exemplarily, the material plate 3 is sequentially divided into a first punching area, a second punching area, and a third punching area along the first direction, with the first punching area facing the side where the blanking punch 25 is located. Specifically, during the movement of the material plate 3 along the first direction on the lower die plate 11, when the first punching area reaches the position of the first outer punch 221 and the first inner punch 222, the movement pauses, the upper die plate 21 and the lower die plate 11 close, and the first outer punch 221 and the first inner punch 222 punch on the material plate 3 to obtain a first outer profile blank surface 301 and a second outer profile blank surface 302. Both the first outer profile blank surface 301 and the second outer profile blank surface 302 have a first punching gap with the workpiece 4, the first punching gap being referenced to... Figure 6As shown at point A, the first blanking clearance is 20%t-30%t. At this time, there is a large machining allowance between the first outer blank surface 301 and the second outer blank surface 302 and the corresponding edge of the workpiece 4. Taking t as the thickness of the workpiece 4 as an example, the machining allowance between the first outer blank surface 301 and the second outer blank surface 302 and the corresponding edge of the workpiece 4 is 20%-30% of the thickness of the workpiece 4. It is worth mentioning that at this time, the second and third blanking areas have not yet performed any blanking work. Subsequently, the upper die 21 and the lower die 11 separate, the material plate 3 continues to move, and the first blanking area stops moving when it reaches the position of the second outer punch 231 and the second inner punch 232. At this time, the second blanking area also moves to the position of the first outer punch 221 and the first inner punch 222. The upper template 21 and the lower template 11 are closed. The second outer punch 231 and the second inner punch 232 punch on the material plate 3 to further obtain the third outer contour blank surface 303 and the fourth outer contour blank surface 304. Both the third outer contour blank surface 303 and the fourth outer contour blank surface 304 have a second punching gap with the workpiece 4. The second punching gap is referenced to... Figure 6 As shown at point B, the second blanking clearance is 5%t-7%t. At this time, the machining allowance between the third outer blank surface 303 and the fourth outer blank surface 304 and the corresponding edge of the workpiece 4 decreases. Taking t as the thickness of the workpiece 4 as an example, the machining allowance between the third outer blank surface 303 and the fourth outer blank surface 304 and the corresponding edge of the workpiece 4 is 5%-7% of the thickness of the workpiece 4. It is worth mentioning that at this time, the second blanking area performs blanking work through the first outer punch 221 and the first inner punch 222, while the third blanking area has not yet performed any blanking work. Subsequently, the upper die plate 21 and the lower die plate 11 separate, and the material plate 3 continues to move. When the first blanking area moves to the position of the third outer punch 241 and the third inner punch, it pauses its movement. At this time, the second blanking area also moves to the position of the second outer punch 231 and the second inner punch 232, and the third blanking area also moves to the position of the first outer punch 221 and the first inner punch 222. The upper template 21 and the lower template 11 close together, and the third outer punch 241 punches on the material plate 3 to further obtain the fifth outer contour blank surface 305. The fifth outer contour blank surface 305 and the workpiece 4 have a third punching clearance, which is referenced... Figure 6As shown at point C, the third blanking clearance is 0.5%t-1%t. At this time, the machining allowance between the fifth outer blank surface 305 and the corresponding edge of the workpiece 4 is further reduced. Taking t as the thickness of the workpiece 4 as an example, the machining allowance between the fifth outer blank surface 305 and the corresponding edge of the workpiece 4 is 0.5%-1% of the thickness of the workpiece 4. It is worth mentioning that at this time, the second blanking area performs blanking work through the second outer punch 231 and the second inner punch 232, and the third blanking area performs blanking work through the first outer punch 221 and the first inner punch 222. Subsequently, the upper die plate 21 and the lower die plate 11 separate, and the material plate 3 continues to move. When the first blanking area moves to the position of the blanking punch 25, it pauses its movement. At this time, the second blanking area also moves to the position of the third outer punch 241, and the third blanking area also moves to the position of the second outer punch 231 and the second inner punch 232. The upper die 21 and lower die 11 close together, and the blanking punch 25 performs blanking on the material plate 3 to obtain the workpiece 4. Simultaneously, the second blanking area performs blanking through the third outer punch 241, and the third blanking area performs blanking through the second outer punch 231 and the second inner punch 232. This process integrates multiple blanking operations from roughing to finishing, effectively improving the integration and functionality of the processing equipment and ensuring efficient processing of the workpiece 4.

[0068] Furthermore, the upper template 21 is provided with a first outer punch 221, a second outer punch 231, and a third outer punch 241 on opposite sides along the second direction. At least two first inner punches 222 and at least two second inner punches 232 are spaced apart along the second direction. The material plate 3 is cut by the first outer punch 221 and the closest first inner punch 222 on the same side to form a first connecting portion 34. The material plate 3 is cut by two adjacent first inner punches 222 to form a second connecting portion 35. The first connecting portion 34 is cut by the second outer punch 231 and the closest second inner punch 232 on the same side to form a third connecting portion 36. The second connecting portion 35 is cut by two adjacent second inner punches 232 to form a fourth connecting portion 37. The third connecting portion 36 is cut by the third outer punch 241 to form a fifth connecting portion 38. Specifically, the first connecting part 34 and the second connecting part 35 ensure that the material plate 3 can be reliably and effectively connected between two adjacent workpiece 4 blanks after one stamping by the first outer contour punch group. The third connecting part 36 and the fourth connecting part 37 ensure that the material plate 3 can be reliably and effectively connected between two adjacent workpiece 4 blanks after a second stamping by the second outer contour punch group. The fifth connecting part 38, in conjunction with the fourth connecting part 37, ensures that the material plate 3 can be reliably and effectively connected between two adjacent workpiece 4 blanks after a third stamping by the third outer contour punch group.

[0069] Specifically, there are two first outer punches 221 spaced apart along the second direction, two second outer punches 231 spaced apart along the second direction, and two third outer punches 241 spaced apart along the second direction. There are two first inner punches 222 spaced apart along the second direction, and two second inner punches 232 spaced apart along the second direction.

[0070] Furthermore, the end face of the upper template 21 facing the lower template 11 is also provided with multiple positioning punches 29, which are used to punch positioning holes 33 on the material plate 3. During the mold closing process of the upper template 21 and the lower template 11, the positioning punches 29 punch positioning holes 33 at the corresponding positions on the material plate 3. This arrangement ensures that the positioning punches 29 and the positioning holes 33 are in an inserted positioning state during the mold closing process, thereby achieving effective positioning of the material plate 3 and preventing the material plate 3 from moving arbitrarily.

[0071] Furthermore, the end face of the upper template 21 facing the lower template 11 is also provided with a plurality of positioning blocks 217. The positioning blocks 217 can abut against the edge of the material plate 3, thereby also serving to position the material plate 3. For example, Figure 6 In the embodiment shown, the positioning blocks 217 are distributed on both sides of the material plate 3 along the second direction, and the positioning blocks 217 abut against the third outer contour blank surface 303 on the corresponding side.

[0072] Furthermore, the lower mold mechanism 1 also includes a bottom support plate 12, and the lower mold plate 11 is fixedly supported on the bottom support plate 12. The bottom support plate 12 has a support end face 121, and the lower mold plate 11 is provided with a first through hole 111, a second through hole 112, a third through hole 113, a fourth through hole 114, a fifth through hole 115 and a sixth through hole 116. Specifically, the scrap cut by the first outer punch 221 falls onto the support end face 121 through the first through hole 111; the scrap cut by the first inner punch 222 falls onto the support end face 121 through the second through hole 112; the scrap cut by the second outer punch 231 falls onto the support end face 121 through the third through hole 113; the scrap cut by the second inner punch 232 falls onto the support end face 121 through the fourth through hole 114; the scrap cut by the third outer punch 241 falls onto the support end face 121 through the fifth through hole 115; and the workpiece 4 cut by the blanking punch 25 falls onto the support end face 121 through the sixth through hole 116. In particular, the scrap cut from the material plate 3 eventually falls onto the bottom support plate 12, where it is reliably collected.

[0073] Specifically, the lower template 11 is fixedly supported on the bottom support plate 12 by multiple support heads 124.

[0074] Furthermore, the lower template 11 is provided with air blowing holes 117 that connect to the first through hole 111, the second through hole 112, the third through hole 113, the fourth through hole 114, the fifth through hole 115, and the sixth through hole 116. Specifically, by providing air blowing holes 117, an external air blowing device can be connected to blow air into the first through hole 111, the second through hole 112, the third through hole 113, the fourth through hole 114, the fifth through hole 115, and the sixth through hole 116, ensuring that the punched waste material can fall effectively.

[0075] Furthermore, the bottom support plate 12 has a water groove 122 surrounding the support end face 121, and the side of the bottom support plate 12 has a water outlet 123 communicating with the water groove 122. Specifically, the first outer punch 221, the first inner punch 222, the second outer punch 231, the second inner punch 232, the third outer punch 241, and the feeding punch 25 are all provided with water outlet gaps (not shown) between them and the upper template 21. The upper template 21 has a water inlet 213, which communicates with the water outlet gap. Specifically, the inlet 213 is connected to a water source, which flows out through the outlet gap. During the punching process, water passes over the outer edges of the first outer punch 221, the first inner punch 222, the second outer punch 231, the second inner punch 232, the third outer punch 241, and the blanking punch 25. This lubricates and cools the punching contact surfaces, promotes the falling and separation of the punched waste, and prevents the punched waste from sticking together. After flowing downwards, the water falls onto the support end face 121 of the bottom support plate 12 and eventually flows into the water tank 122, where it is discharged through the outlet 123.

[0076] In this embodiment, the end face of the upper template 21 facing the lower template 11 is sequentially provided with a first punch 26, a second punch 27, and a chamfering punch 28 along a first direction, and a third punch 251 is provided on the blanking punch 25. The first punch 26 is used to punch the material plate 3 once to form a first blank 31, and there is a fourth punching gap between the first blank 31 and the machining hole 41 on the workpiece 4. The second punch 27 is used to punch the first blank 31 a second time to form a second blank 32, and there is a fifth punching gap between the second blank 32 and the machining hole 41, the fourth punching gap being larger than the fifth punching gap. The chamfering punch 28 is used to chamfer the second blank 32. The third punch 251 protrudes outward from the blanking punch 25 and is used to punch the chamfered second blank 32 a third time to form the machining hole 41 on the workpiece 4.

[0077] Specifically, in this embodiment, the fourth blanking gap is 20%t-30%t, and the fifth blanking gap is 1%t-3%t.

[0078] By setting the first hole punch 26, the second hole punch 27, the chamfering punch 28, and the third hole punch 251, multiple processing steps from roughing to finishing can be achieved for the machining hole 41, ultimately producing the corresponding machining hole 41 on the workpiece 4. Specifically, during the movement of the material plate 3 along the first direction on the lower template 11, the movement is paused when the target opening position on the material plate 3 moves to the position directly opposite the first hole punch 26. The upper template 21 and the lower wooden board are closed, and the first hole punch 26 punches out the first hole blank 31 on the material plate 3. The fourth punching gap between the first hole blank 31 and the machining hole 41 on the workpiece 4 is 20%t-30%t, indicating that the machining allowance between the first hole blank 31 and the target machining hole 41 is relatively large. Subsequently, the upper mold plate 21 and the lower mold plate 11 separate, and the material plate 3 continues to move until the first hole blank 31 moves to the position directly opposite the second hole punch 27, at which point the movement stops. The upper mold plate 21 and the lower mold plate 11 then close, and the second hole punch 27 further punches the first hole blank 31 to obtain the second hole blank 32. The fifth punching clearance between the second hole blank 32 and the machining hole 41 is 1%t-3%t, and the machining allowance between the second hole blank 32 and the target machining hole 41 is further reduced. Subsequently, the upper mold plate 21 and the lower mold plate 11 separate, and the material plate 3 continues to move until the second hole blank 32 moves to the position directly opposite the chamfering punch 28, at which point the movement stops. The upper mold plate 21 and the lower mold plate 11 then close, and the chamfering punch 28 processes a chamfer on the second hole blank 32. Then the upper template 21 and the lower template 11 separate, and the material plate 3 continues to move until the third hole punch 251 is directly facing the second hole blank 32. At this time, the blanking punch 25 is also directly facing the workpiece 4 to be punched on the material plate 3. At this time, the blanking punch 25 descends. Before the blanking punch 25 contacts the material plate 3, the third hole punch 251 punches the second hole blank 32 and obtains the target machining hole 41.

[0079] Specifically, the lower template 11 has a seventh through hole, an eighth through hole, and a ninth through hole. Among them, the scrap material punched by the first punch 26 falls onto the support end face 121 through the seventh through hole; the scrap material punched by the second punch 27 falls onto the support end face 121 through the eighth through hole; the scrap material punched by the chamfering punch 28 falls onto the support end face 121 through the ninth through hole; and the workpiece 4 punched by the third punch 251 falls onto the support end face 121 through the sixth through hole 116.

[0080] Specifically, the air blowing hole 117 is also connected to the seventh through hole, the eighth through hole, and the ninth through hole. The air blowing hole 117 is connected to an external air blowing device, thereby blowing air into the seventh through hole, the eighth through hole, and the ninth through hole to ensure that the punched waste can fall effectively.

[0081] Specifically, the first hole punch 26, the second hole punch 27 and the chamfering punch 28 are all provided with water outlet gaps (not shown) between them and the upper template 21, and the water inlet 213 of the upper template 21 is connected to the water outlet gap.

[0082] Furthermore, a scrap punch 216 is provided on the end face of the upper template 21 facing the lower template 11, and the scrap punch 216 is located downstream of the blanking punch 25. By providing the scrap punch 216, the scrap of the material plate 3 that has been punched by the blanking punch 25 can be punched, so that the scrap finally falls onto the bottom support plate 12 for collection.

[0083] In this embodiment, an elastic reset member 13 is further included between the upper template 21 and the lower template 11. The elastic reset member 13 ensures that the upper template 21 always tends to move away from the lower template 11. By providing the elastic reset member 13, the upper template 21 and the lower template 11 can always tend to open, ensuring effective separation between the upper template 21 and the lower template 11.

[0084] In this embodiment, one of the upper mold plate 21 and the lower mold plate 11 is provided with a guide post 14, and the other is provided with a guide cylinder 210. The guide cylinder 210 is slidably sleeved on the guide post 14. Specifically, the guide post 14 is provided on the lower mold plate 11, and the guide cylinder 210 is provided on the upper mold plate 21. The sliding cooperation between the guide cylinder 210 and the guide post 14 can provide a reliable and effective guiding effect for the lifting and lowering movement between the upper mold plate 21 and the lower mold plate 11, further ensuring the reliability and effectiveness of the mold closing and opening actions.

[0085] Specifically, the elastic reset element 13 is configured as a spring, which is sleeved on the guide post 14. One end of the spring abuts against the lower template 11, and the other end abuts against the guide cylinder 210. This configuration provides a reliable installation space for the spring and prevents it from accidentally popping out.

[0086] In this embodiment, the lower mold mechanism 1 further includes a lower lifting head 15 disposed on the side end of the lower template 11, and the upper mold mechanism 2 includes an upper lifting head 211 disposed on the side end of the upper template 21. Specifically, the lower template 11 has multiple lower lifting heads 15 at both opposite ends along the first direction, and the upper template 21 has multiple upper lifting heads 211 at both opposite ends along the first direction. The arrangement of the upper lifting heads 211 and lower lifting heads 15 facilitates the lifting of the upper mold mechanism 2 and the lower mold mechanism 1, thereby facilitating the transportation of the entire equipment.

[0087] In this embodiment, an upper limit head 212 is provided on the side of the upper mold plate 21 facing the lower mold plate 11, and a lower limit head 16 is correspondingly provided on the side of the lower mold plate 11 facing the upper mold plate 21. The upper limit head 212 and the lower limit head 16 are correspondingly provided. Specifically, when the upper mold plate 21 and the lower mold plate 11 are in the mold closing position, the upper limit head 212 abuts against the lower limit head 16, thereby playing a role in abutting and limiting.

[0088] In this embodiment, the upper mold plate 21 has an upper locking groove 214 on its edge, and the lower mold plate 11 has a lower locking groove 17 on its edge. The upper locking groove 214 and the lower locking groove 17 are correspondingly provided. By providing the upper locking groove 214 and the lower locking groove 17, when the upper mold plate 21 and the lower mold plate 11 are in the mold-closed position, by simultaneously inserting the locking member into the upper locking groove 214 and the lower locking groove 17, the upper mold plate 21 and the lower mold plate 11 can be locked, thereby keeping the upper mold plate 21 and the lower mold plate 11 in the mold-closed state.

[0089] Alternatively, the locking element can be a bolt assembly.

[0090] In this embodiment, one of the upper mold plate 21 and the lower mold plate 11 is provided with a guide head 215, and the other is provided with a guide hole 18. Specifically, multiple guide heads 215 are provided on the upper mold plate 21, and multiple guide holes 18 are provided on the lower mold plate 11. The multiple guide heads 215 and multiple guide holes 18 are provided in a one-to-one correspondence. The guide heads 215 are slidably inserted into the corresponding guide holes 18. The corresponding cooperation between the guide heads 215 and the guide holes 18 can further provide a guiding effect between the upper mold plate 21 and the lower mold plate 11, ensuring reliable and stable mold closing and opening operations.
