Description

Technical Field

[0001] This invention relates to the field of metal composite processing equipment technology, and in particular to a continuous composite cutting equipment for stepped grooves in copper blocks. Background Technology

[0002] Due to its excellent thermal conductivity, electrical conductivity, and ductility, copper is widely used in electronics, electrical engineering, heat dissipation, and precision machinery. T-shaped copper blocks are often used in high-current busbars, switchgear conductive busbars, transformer terminals, etc., as their T-shaped cross-section design can provide a larger conductive cross-sectional area within a limited space.

[0003] In some applications, it is often necessary to machine a stepped groove structure at one end of the T-shaped copper block, as shown in the attached figure. Figure 12 As shown, the processing of this stepped groove requires removing a portion of both the horizontal and vertical plates of the T-shaped copper block, and the resulting scrap block also has a T-shaped cross-section. Currently, the processing of stepped grooves in this type of T-shaped copper block typically employs a step-by-step processing method, first cutting horizontally and then vertically. First, the bottom vertical plate is cut horizontally, and then the top horizontal plate and part of the vertical plate are cut vertically, ultimately forming the stepped groove.

[0004] In the prior art, separate horizontal and vertical cutting devices are usually used to perform two cuts. For example, a steel structure cutting device disclosed in patent CN214770294U includes a cutting platform and a cutting machine. The surface of the cutting platform is provided with slide rails and a material trough. The slide rails include a first slide rail and a second slide rail. The ends of the first and second slide rails are provided with a first cylinder. The output end of the first cylinder is connected to the cutting machine. The cutting machine is slidably connected to the first and second slide rails and is provided with a cutting torch. A rotating motor is provided on the side. The output end of the rotating motor is provided with a grinding disc. The surface of the material trough is provided with a third slide rail. A platform is provided on the third slide rail, and a second cylinder is provided at its end.

[0005] The cutting machines on the first and second slide rails of this device can perform transverse and longitudinal cutting respectively to process stepped grooves on the metal block. The metal block can also be ground after cutting to achieve composite processing. However, this device only has a structure for clamping and positioning the main body of the metal block, and lacks a structure for clamping and positioning the portion to be cut off.

[0006] If this equipment is used to machine stepped grooves on a copper block, after the horizontal cut, the portion to be removed from the copper block is only connected to the parent material through the uncut area. During the second vertical cut, the scrap piece to be removed is suspended in mid-air, connected only to the main body of the copper block by its vertical sidewall, lacking effective positioning and rigid support. As the vertical cut progresses, the connecting area gradually decreases. Under the influence of cutting force and its own weight, the scrap piece will tilt or wobble relative to the main body of the copper block. This affects the quality of the vertical cut surface, resulting in noticeable ripples, tears, and even uneven stepped surfaces and excessive verticality. The dimensional accuracy and surface quality of the stepped groove are also affected. Summary of the Invention

[0007] This invention provides a continuous composite cutting equipment for stepped grooves on copper blocks to solve the technical problem that existing composite processing equipment used to cut stepped grooves on copper blocks cannot support the waste block used to form the stepped grooves during the secondary cutting process, and the waste block is prone to tilting and shaking, affecting the forming quality of the cut surface.

[0008] To solve the above problems, the present invention provides a continuous composite cutting equipment for stepped grooves in copper blocks, which adopts the following technical solution: A continuous composite cutting equipment for stepped grooves of copper blocks includes a main positioning mechanism for clamping and positioning the main body of a T-shaped copper block, a transverse cutting mechanism for primary cutting, and a longitudinal cutting mechanism for secondary cutting. It also includes a waste block positioning mechanism for clamping and positioning the T-shaped scrap blocks to be cut. The waste block positioning mechanism includes a vertical positioning structure and a lateral positioning structure. The vertical positioning structure supports the T-shaped scrap block from bottom to top during the secondary cutting process, while the lateral positioning structure laterally limits the T-shaped scrap block along the travel direction of the longitudinal cutting mechanism during the secondary cutting process. The waste block positioning mechanism can move up and down. During the primary cutting process, the waste block positioning mechanism is located below the transverse cutting mechanism. Before the secondary cutting, the waste block positioning mechanism rises to a set position so that the vertical positioning structure supports the T-shaped scrap block and the lateral positioning structure blocks the T-shaped scrap block in the travel path of the longitudinal cutting mechanism.

[0009] By adopting the above technical solution, a scrap block positioning mechanism that can move up and down is set up. Before the secondary cutting, the scrap block rises to a predetermined position. A vertical positioning structure supports the T-shaped scrap block from bottom to top, while a lateral positioning structure provides lateral restraint along the cutting direction. This ensures that the scrap block receives rigid support and reliable positioning throughout the vertical cutting process, effectively preventing skewing or shaking caused by cutting force and its own weight. This improves the flatness and verticality of the vertical cut surface, ensures the dimensional accuracy and surface quality of the stepped groove, reduces subsequent secondary finishing processes, and increases processing efficiency. The scrap block positioning mechanism can move up and down, remaining at a lower position during the first cutting process, exposing the area of ​​the T-shaped copper block to be cut and avoiding interference with the cutting process.

[0010] Furthermore, the vertical positioning structure includes two horizontally arranged horizontal positioning plates, which are spaced apart in the horizontal direction. When the waste block positioning mechanism rises to the set position, the two horizontal positioning plates are respectively supported on the two bottom surfaces of the horizontal plate in the T-shaped waste block located on both sides of the vertical plate.

[0011] By adopting the above technical solution, two horizontally spaced positioning plates are set up and placed on the two bottom surfaces of the T-shaped waste block where the horizontal plate is located on both sides of the vertical plate after the waste block positioning mechanism rises. This achieves symmetrical support for the bottom of both sides of the waste block, resulting in high support stability and uniform force distribution. It avoids the tilting of the waste block caused by single-point support, further ensuring the stability of the waste block's posture during the secondary cutting process and facilitating the acquisition of a high-quality cutting surface.

[0012] Furthermore, the lateral positioning structure includes two vertically arranged side baffles, which are horizontally arranged opposite each other. During the upward movement of the waste block positioning mechanism, the T-shaped waste block is inserted between the two side baffles, and the two side baffles are respectively fixedly positioned on the two side walls of the horizontal plate of the T-shaped waste block located on both sides of the vertical plate.

[0013] By adopting the above technical solution, two horizontally arranged side baffles are set up so that the T-shaped waste block is inserted between the two plates during the upward movement of the waste block positioning mechanism. The T-shaped waste block is blocked on the two side walls of the horizontal plate located on both sides of the vertical plate, thereby realizing bidirectional limiting of the waste block along the cutting direction. This effectively restricts the lateral movement or twisting of the waste block that may occur during the vertical cutting process. It complements the vertical positioning structure and further enhances the positioning reliability.

[0014] Furthermore, the two side baffles are respectively connected to the two horizontal positioning plates and are located above the horizontal positioning plates.

[0015] By adopting the above technical solution, the two side baffles are respectively connected to the two horizontal positioning plates and located above the horizontal positioning plates, so that the lateral positioning structure and the vertical positioning structure are integrated into one, which simplifies the overall structure of the waste block positioning mechanism, reduces the number of parts, and ensures the relative positional accuracy between the side baffles and the horizontal positioning plates. During the rising process, it can simultaneously achieve support and lateral limiting, with good action coordination and strong positioning consistency.

[0016] Furthermore, the main positioning mechanism includes a bracket, a positioning seat, a positioning baffle, and a clamping drive. The positioning seat is fixed on the bracket and has a horizontally penetrating positioning groove for the T-shaped copper block to slide through. The positioning baffle is arranged vertically and is elastically slidably connected to the bracket along the extension direction of the positioning groove. The positioning baffle is used to press against the T-shaped end face of the T-shaped copper block on the processing side. An adjusting bolt is also threaded onto the bracket. The adjusting bolt is located on the side of the positioning baffle facing away from the positioning seat, and there is a horizontal gap between the adjusting bolt and the positioning seat. The clamping drive has a drive output end that can extend and retract along the extension direction of the positioning groove. The clamping drive can drive the T-shaped copper block to move toward the positioning baffle and push the positioning baffle to press against the adjusting bolt.

[0017] The above technical solution adopts a structure that combines a positioning seat, a positioning groove, an elastically sliding positioning baffle, and an adjusting bolt. Under the action of the clamping drive, the T-shaped copper block is pushed against the positioning baffle and finally the positioning baffle is pressed against the adjusting bolt, thus achieving stable clamping of the main body of the copper block in the processing direction. The adjusting bolt can adjust the clamping position to meet various size requirements.

[0018] Furthermore, the waste block positioning mechanism is elastically slidably mounted on the bracket along the extension direction of the positioning groove. A locking structure is provided between the waste block positioning mechanism and the positioning baffle. The locking structure has a locked state and an unlocked state. When the locking structure is in the locked state, the waste block positioning mechanism can move synchronously with the positioning baffle pushed by the T-shaped copper block. When the locking structure is in the unlocked state, the waste block positioning mechanism and the positioning baffle are disengaged from synchronous movement. The locking structure remains locked during the process of the positioning baffle being driven by the T-shaped copper block to move towards the adjusting bolt, so that the waste block positioning mechanism is driven to move synchronously by the positioning baffle. After the secondary cutting is completed, the locking structure switches to the unlocked state, so that the waste block positioning mechanism and the positioning baffle are disengaged from synchronous movement and elastically reset. The top of both horizontal positioning plates is provided with a first polishing layer, and the opposite side of both side baffles is provided with a second polishing layer.

[0019] By adopting the above technical solution, the waste block positioning mechanism is elastically slidably installed on the bracket and a locking structure is set to cooperate with the positioning baffle. When the positioning baffle is moved by the T-shaped copper block, the waste block positioning mechanism can move synchronously with it. After the secondary cutting is completed, the mechanism is unlocked and elastically reset. The waste block positioning mechanism and the T-shaped copper block slide relative to each other. Grinding layer one and grinding layer two grind the cut area, integrating the positioning support and grinding functions into one, reducing the additional grinding process.

[0020] Furthermore, the waste block positioning mechanism also includes two vertically arranged connecting plates. The two connecting plates are respectively connected to two horizontal positioning plates and located below the horizontal positioning plates. The two connecting plates are used to be set on both sides of the vertical plate in the T-shaped copper block. The opposing side of the two connecting plates is provided with a polishing layer.

[0021] By adopting the above technical solution, two connecting plates are set below the horizontal positioning plate, and a grinding layer three is set on the opposite side of the two connecting plates, so that it abuts against the outer wall of the vertical plate in the T-shaped copper block. During the reset process of the waste block positioning mechanism, the grinding layer three can be used to grind the cut seam on the vertical plate. There is no need to arrange a separate grinding station, which realizes the online trimming of the cut surface of the vertical plate, further improves the overall surface quality of the stepped groove, and shortens the auxiliary processing time.

[0022] Furthermore, a horizontal top plate is connected to the waste block positioning mechanism. When the horizontal positioning plate supports the waste block, the bottom surface of the horizontal top plate is flush with the top surface of the waste block. A grinding layer is provided at the bottom of the horizontal top plate.

[0023] By adopting the above technical solution, a horizontal top plate is connected to the waste block positioning mechanism, and the bottom surface of the horizontal top plate is flush with the top surface of the waste block in the supporting state. At the same time, a grinding layer four is set at the bottom of the horizontal top plate. The horizontal top plate forms an auxiliary limit on the upper part of the waste block, and the cutting marks on the top surface of the T-shaped copper block can be ground by relative movement after cutting, which is beneficial to improving the overall surface quality of the workpiece after processing.

[0024] Furthermore, the waste block positioning mechanism has a limiting plate, and the positioning baffle is provided with a locking plate that can move up and down. When the locking plate moves down to be horizontally opposite to the limiting plate and located on the side of the limiting plate away from the adjusting bolt, the locking structure is in a locked state. When the locking plate moves up to be offset from the limiting plate, the locking structure is in an unlocked state.

[0025] By adopting the above technical solution, the locking structure is set to cooperate with the limiting plate and the locking plate that can move up and down. When the locking plate moves down to be horizontally opposite to the limiting plate and located on the side of the limiting plate away from the connecting bolt, the locking is achieved by the interference between the limiting plate and the locking plate in the horizontal direction. The structure is simple and highly reliable. When the locking plate moves up to be offset from the limiting plate, it can be quickly unlocked. The switching action is simple and efficient.

[0026] Furthermore, rubber layers are provided on the opposing sidewalls of the two side panels.

[0027] Using the above technical solution, the rubber layer can generate greater resistance to the T-shaped waste block. After the cutting is completed, the positioning baffle resets and pushes the T-shaped copper block to fall. The rubber layer on the side baffle prevents the T-shaped waste block from moving synchronously with the main body of the T-shaped copper block, thus separating the T-shaped waste block from the main body of the T-shaped copper block and avoiding adhesion.

[0028] The beneficial effects of the continuous composite cutting equipment for stepped grooves of copper blocks provided by this invention are as follows: By setting up a waste block positioning mechanism that can move up and down, the waste block rises to a set position before secondary cutting. A vertical positioning structure provides rigid support from bottom to top, and a lateral positioning structure provides reliable limiting along the cutting direction. This solves the problem of swaying and shaking caused by the suspended waste block and lack of positioning support in existing equipment, improving the flatness and verticality of the stepped groove cutting surface and ensuring dimensional accuracy and surface quality. Simultaneously, after cutting, the cut marks can be polished, reducing secondary finishing processes and achieving highly efficient continuous composite cutting of T-shaped copper block stepped grooves.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] The following is one embodiment of a continuous composite cutting equipment for stepped grooves of copper blocks provided by the present invention: like Figures 1-12 As shown, a continuous composite cutting equipment for stepped grooves in copper blocks is used for cutting such... Figure 12A T-shaped scrap block 8 is cut from the T-shaped copper block 7 shown, thus forming a stepped groove.

[0033] The continuous composite cutting equipment for stepped grooves of copper blocks includes a frame 1, a main positioning mechanism, a waste block positioning mechanism, a locking structure, a transverse cutting mechanism 3, and a longitudinal cutting mechanism 4.

[0034] like Figure 1 As shown, the frame 1 is arranged on a horizontal ground, and the frame 1 is provided with a sliding seat 2 that can slide in the front-back direction.

[0035] The main positioning mechanism is installed on the aforementioned sliding seat 2, such as Figure 2 As shown, the main positioning mechanism includes a bracket 6, a positioning seat 5, a positioning baffle 11, an adjusting bolt 13, and a clamping drive component.

[0036] like Figure 1 , Figure 2 As shown, the bracket 6 is mounted on the sliding seat 2. The bracket 6 includes a left bracket 601 and a right bracket 602. The left bracket 601 has a receiving cavity 603, and a lifting drive component 23 is provided in the receiving cavity 603. The lifting drive component 23 is a lifting cylinder, and the lifting cylinder has a lifting output end that can move up and down. Figure 9 As shown, a lifting plate 10 extending in the left-right direction is connected to the lifting output end of the lifting cylinder.

[0037] like Figure 4 As shown, guide rod 14 and guide rod 25, both extending in the left-right direction, are fixedly connected to the right-side frame 602. Guide rod 14 and guide rod 25 are distributed at intervals from top to bottom. Figure 2 As shown, the right side frame 602 is also provided with a guide groove 604 extending in the vertical direction, and the right end of the lifting plate 10 slides through the guide groove 604.

[0038] like Figure 2 , Figure 3 As shown, the positioning seat 5 is fixedly installed on the top of the left side frame 601. The positioning seat 5 is integrally formed with the left side frame 601. The positioning seat 5 includes two vertical plates 502 and two horizontal plates 501. The two vertical plates 502 are spaced apart in the front-back direction and remain parallel. The two horizontal plates 501 are respectively connected to the top of the two vertical plates 502. A positioning groove 503 extending left and right is formed between the two vertical plates 502. The groove width of the positioning groove 503 is adapted to the thickness of the vertical plate in the T-shaped copper block 7 so that the vertical plate in the T-shaped copper block 7 can be inserted. The two horizontal plates 501 are respectively used to support the two parts of the horizontal plate in the T-shaped copper block 7 located on both sides of the vertical plate.

[0039] like Figure 2 , Figure 4 , Figure 5As shown, the positioning baffle 11 extends vertically and is guided and slidably mounted on the right side frame 602 in the left-right direction, and is slidably fitted onto the aforementioned guide rod 14. An elastic element 16, which is a tension spring, is connected between the positioning baffle 11 and the left side frame 601 and is fitted on the outside of the guide rod 14. When the elastic element 16 is in a free state, the positioning baffle 11 is located at the left end of the right side frame 602.

[0040] The adjusting bolt 13 is arranged horizontally and is located on the right side of the positioning baffle 11. The thread of the adjusting bolt 13 is screwed onto the right side bracket 602. The end of the adjusting bolt 13 is set to the left. There is a horizontal gap between the adjusting bolt 13 and the positioning seat 5.

[0041] The clamping drive component employs a horizontally arranged drive cylinder. The right side of the drive cylinder has a drive output end capable of extending and retracting left and right, which is positioned opposite the positioning slide groove 503. When the drive output end of the drive cylinder extends to the right, it moves the T-shaped copper block 7 within the positioning slide groove 503 to the right. The T-shaped copper block 7 contacts the positioning baffle 11 and moves the positioning baffle 11 to the right. When the positioning baffle 11 contacts the adjusting bolt 13, it is stopped by the adjusting bolt 13 and no longer moves to the right. At this point, the T-shaped copper block 7 is clamped by the drive cylinder and the positioning baffle 11. When the drive output end of the drive cylinder retracts, the positioning baffle 11 resets to the left under the action of the elastic element 16, pushing the T-shaped copper block 7 to the left.

[0042] By turning the adjusting bolt 13, the position of the left end of the adjusting bolt 13 in the horizontal direction can be changed, thereby changing the limit position that the positioning baffle 11 can move to the right. In this way, without changing the position of the cutting mechanism, the horizontal position of the cut on the T-shaped copper block 7 can be adjusted, thereby changing the size of the cut waste block in the left and right direction, which is suitable for processing stepped grooves of different sizes.

[0043] The waste block positioning mechanism is installed on the main positioning mechanism. The waste block positioning mechanism includes a vertical positioning structure, a lateral positioning structure, a connecting plate 21, a bottom connecting plate 22, a mating plate 18, and a horizontal top plate 24.

[0044] like Figure 2 , Figure 3 , Figure 7 , Figure 9 As shown, the vertical positioning structure includes two horizontal positioning plates 20 arranged symmetrically with a front-to-back gap. The two horizontal positioning plates 20 are respectively used to support the bottom of the two parts of the horizontal plate in the cut T-shaped waste block 8 located on the front and back sides of the vertical plate. The top of the horizontal positioning plate 20 is provided with a polishing layer 1, which has a rough frosted outer surface. When the horizontal positioning plate 20 supports the bottom of the horizontal plate in the T-shaped waste block 8, the polishing layer 1 is in contact with the bottom surface of the horizontal plate in the T-shaped waste block 8.

[0045] The lateral positioning structure includes two side baffles 9 arranged at a distance from each other, vertically aligned and parallel. The two side baffles 9 are connected to two horizontal positioning plates 20, located at opposite ends of the horizontal positioning plates 20. The horizontal positioning plates 20 and their corresponding side baffles 9 are integrally formed. A second polishing layer is provided on the side of each side baffle 9 facing the other side baffle 9. This second polishing layer has a rough, frosted outer surface. When the two side baffles 9 are positioned on the front and rear sides of the horizontal plate in the T-shaped waste block 8, the second polishing layer on each side adheres to the front and rear sidewalls of the horizontal plate in the T-shaped waste block 8. A rubber layer is also provided on the inner side of each side baffle 9. The second polishing layer and the rubber layer are distributed sequentially from left to right, and both can adhere to the outer sidewall of the horizontal plate in the T-shaped waste block 8.

[0046] Two connecting plates 21 are provided, which are vertically extending strip plates. The two connecting plates 21 are arranged at intervals and parallel to each other, and are respectively connected to the bottom of the two horizontal positioning plates 20, and are respectively located at the two opposite ends of the two horizontal positioning plates 20. Figure 9 As shown, both connecting plates 21 have vertical grooves 211 on their opposite sides. Both connecting plates 21 also have a grinding layer 3 on their opposite sides. The grinding layer 3 is located on the top of the connecting plates 21. The vertical dimension of the grinding layer 3 is larger than the length of the cut extending vertically on the vertical plate of the T-shaped copper block 7, so that the grinding layer 3 can grind the cut on the vertical plate of the T-shaped copper block 7.

[0047] like Figure 2 , Figure 3 , Figure 9 As shown, the bottom connecting plate 22 is horizontally positioned and connected between the bottom ends of the two connecting plates 21. The bottom connecting plate 22, connecting plates 21, horizontal positioning plate 20, and side baffle 9 are integrally formed. The bottom connecting plate 22 is slidably mounted on the lifting plate 10 in the left-right direction. When the lifting plate 10 is driven to move up and down, it can drive the bottom connecting plate 22 to move up and down, thereby driving the entire waste block positioning mechanism to move up and down.

[0048] The mating plate 18 is installed between the two connecting plates 21 by sliding up and down through the vertical slide groove 211. The mating plate 18 can move synchronously with the entire waste block positioning mechanism in the left and right direction. A limiting plate 25 is provided on the right side of the top of the mating plate 18.

[0049] like Figure 5 , Figure 6As shown, the mating plate 18 is slidably fitted onto the guide rod 15 in the left-right direction, so that the position of the mating plate 18 in the up-down direction is fixed, and the integrally formed structure containing the connecting plate 21 can slide up and down relative to the mating plate 18. An elastic element 17, which is a tension spring, is provided between the mating plate 18 and the left side frame 601, and is fitted onto the outside of the guide rod 15. When the elastic element 17 is in a free state, the entire waste block positioning mechanism is located at the left end of the right side frame 602.

[0050] The horizontal top plate 24 is connected between the tops of the two side baffles 9 and is located on the right half of the side baffles 9. The bottom of the horizontal top plate 24 is provided with a polishing layer four, which has a rough frosted bottom surface. The polishing layer four is used to abut against the top surface of the T-shaped copper block 7 to polish the cuts on the top surface of the T-shaped copper block 7.

[0051] like Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the locking structure includes a locking drive 12 and a locking plate 19. The locking drive 12 is fixedly installed on the positioning baffle 11. The locking drive 12 is a miniature cylinder with an output end that can extend and retract vertically. The locking plate 19 is connected to the output end of the locking drive 12, and the locking drive 12 can drive the locking plate 19 to move up and down.

[0052] When both the first elastic element 16 and the second elastic element 17 are in a free state, the waste block positioning mechanism and the positioning baffle 11 are located at the left end of the right side frame 602. At this time, the locking plate 19 is located to the left of the upper limit plate 25 of the mating plate 18. The locking drive 12 drives the locking plate 19 to move down, so that the bottom end of the locking plate 19 can move to the left side of the limit plate 25, thereby locking the positioning baffle 11 and the waste block positioning mechanism, so that when the positioning baffle 11 moves to the right, it can drive the waste block positioning mechanism to move to the right synchronously.

[0053] Both the transverse cutting mechanism 3 and the longitudinal cutting mechanism 4 are mounted on the frame 1. Both the transverse cutting mechanism 3 and the longitudinal cutting mechanism 4 adopt sawing mechanisms. The transverse cutting mechanism 3 has a horizontally arranged saw blade for making a first horizontal cut on the T-shaped copper block 7. The longitudinal cutting mechanism 4 has a vertically arranged saw blade for making a second vertical cut on the T-shaped copper block 7. The longitudinal cutting mechanism 4 is located in front of the transverse cutting mechanism 3.

[0054] In use, the transverse cutting mechanism 3 and the longitudinal cutting mechanism 4 are first adjusted to suitable positions. Initially, the locking structure is in a locked state. The vertical plate 502 of the T-shaped copper block 7 is inserted into the positioning groove 503 on the positioning seat 5 from left to right. The clamping drive is activated, pushing the T-shaped copper block 7 to the right, so that the right side wall of the T-shaped copper block 7 contacts the positioning baffle 11, and pushing the positioning baffle 11 to continue moving to the right. When the positioning baffle 11 contacts the left end of the screw in the adjusting bolt 13, the T-shaped copper block 7 is clamped, and the area to be cut in the T-shaped copper block 7 is located between the positioning seat 5 and the positioning baffle 11. During the movement of the positioning baffle 11 to the right, the locking structure drives the waste block positioning mechanism to move to the right synchronously, so that the waste block positioning mechanism is always kept at the right end of the T-shaped copper block 7. During the movement of the positioning baffle 11 and the waste block positioning mechanism to the right, the elastic element 16 and the elastic element 2 17 are both stretched and stored energy.

[0055] Then, the sliding seat 2 is driven to move from back to front, which in turn drives the T-shaped copper block 7 to move from back to front. After passing through the horizontal cutting mechanism 3, the T-shaped copper block 7 completes one cut, and a horizontally extending cut is generated on the vertical plate of the T-shaped copper block 7. At this time, the lifting drive 23 is activated, which drives the lifting plate 10 to move upward. The lifting plate 10 drives the waste block positioning mechanism to move upward, so that the left half of the two horizontal positioning plates 20 supports the bottom of the horizontal plate of the T-shaped waste block 8 that is about to be cut off. At the same time, the left half of the two side baffles 9 are stuck on the front and rear sides of the horizontal plate of the T-shaped waste block 8. The waste block positioning mechanism provides vertical and front-back support and positioning for the T-shaped waste block 8 that is about to be cut off.

[0056] The sliding seat 2 continues to move forward, and the T-shaped copper block 7 is cut a second time by the longitudinal cutting mechanism 4, and the T-shaped waste block 8 is cut off, forming a stepped groove on the T-shaped copper block 7. At this time, the locking drive 12 is activated, which drives the locking plate 19 to move upward. The locking plate 19 moves higher than the limit plate 25, and the positioning baffle 11 and the waste block positioning mechanism are unlocked. The positioning baffle 11 will not move to the left due to the obstruction of the T-shaped copper block 7. The mating plate 18 moves to the left and resets under the action of the elastic element 2 17, which drives the entire waste block positioning mechanism to move to the left and reset. During the process of the waste block positioning mechanism moving to the left, the first polishing layer on the horizontal positioning plate 20, the second polishing layer on the side baffle 9, the third polishing layer on the connecting plate 21, and the fourth polishing layer on the horizontal top plate 24 pass through the cut between the T-shaped copper block 7 and the T-shaped waste block 8, and polish the burrs generated at the cut.

[0057] After the waste block positioning mechanism is reset, the entire waste block positioning mechanism moves to the left side of the slit on the T-shaped copper block 7. The drive output end of the control clamping drive retracts to the left. At this time, the left side of the T-shaped copper block 7 is infinitely positioned. The positioning baffle 11 moves to the left and resets under the action of the elastic element 16. The positioning baffle 11 pushes the T-shaped copper block 7 to the left. The slit on the T-shaped copper block 7 passes through the waste block positioning mechanism from right to left. The slit is polished again by the first polishing layer, the second polishing layer, the third polishing layer, and the fourth polishing layer, realizing secondary polishing. This polishing process can also remove the burrs that were pushed to the left and bent but did not fall off during the first polishing process, thus improving the polishing effect.

[0058] During the aforementioned secondary polishing process, the inner side of the side baffle 9 is equipped with a polishing layer and a rubber layer, which will generate significant resistance to the T-shaped waste block 8. When the T-shaped waste block 8 passes the side baffle 9, it is subjected to the resistance of the polishing layer and the rubber layer on the side baffle 9. Furthermore, since there is no other driving force source on the T-shaped waste block 8, it can no longer move to the left synchronously with the main body of the T-shaped copper block 7. This allows the T-shaped waste block 8 to separate from the main body of the T-shaped copper block 7, preventing adhesion and facilitating the subsequent removal of the T-shaped waste block 8 from the main body of the T-shaped copper block 7.

[0059] In the process of cutting the stepped groove of the T-shaped copper block 7, the present invention can support and position the T-shaped waste block 8 that is about to be cut off after the first cut, so as to avoid the T-shaped waste block 8 shaking during the second cut and affecting the forming quality of the cut surface.

[0060] In this embodiment, the vertical positioning structure includes two horizontal positioning plates 20. In other embodiments, the vertical positioning structure includes two vertically extending positioning rods, which are respectively supported on the two parts of the horizontal plate of the T-shaped waste block 8 located on both sides of the vertical plate.

[0061] In this embodiment, the lateral positioning structure includes two side baffles 9. In other embodiments, the lateral positioning structure includes two uprights, which are respectively positioned on the two wall surfaces of the horizontal plate of the T-shaped waste block 8 located on both sides of the vertical plate.

[0062] In this embodiment, the locking structure uses a locking plate 19 and a limiting plate 25 to lock the positioning baffle 11 and the waste block positioning mechanism. In other embodiments, a locking hole can be provided on the waste block positioning mechanism. By inserting the locking plate 19 into the locking hole, the positioning baffle 11 and the waste block positioning mechanism can be locked.
