The device comprises a laser cutting mechanism which is configured to cut a wire slot to form a wire slot notch; the roller supporting mechanism comprises a first roller supporting part and a second roller supporting part which are oppositely arranged on the two sides of the notch of the wire slot, the first roller supporting part is used for supporting the slot edge at the notch of the wire slot main body section, and the second roller supporting part is used for supporting the slot edge at the notch of the wire slot cutting section; in the process that the laser cutting mechanism cuts the wire groove, the first roller supporting part and the second roller supporting part provide supporting force for the groove edges on the two sides of the notch of the wire groove correspondingly so that the groove edges on the two sides of the notch of the wire groove can be flush. The wire slot cutting device is mainly used for wire slot cutting.

Description

Technical Field

[0001] The invention belongs to the field of metal machining, and in particular relates to laser cutting equipment for wire groove machining. Background Art

[0002] A laser cutting machine uses a laser beam emitted from a laser source and focused into a high-power-density laser beam through an optical system. The laser beam strikes the surface of a metal workpiece, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the beam and the workpiece shift relative to each other, a slit is eventually formed on the workpiece's surface, achieving the desired metal cutting effect. Wire ducts, also known as routing ducts, distribution ducts, and routing ducts, are typically extruded from high-quality aluminum alloy sheet material. Extruded aluminum alloy wire ducts guarantee dimensional accuracy and surface smoothness. Aluminum alloy wire ducts are typically approximately 6 meters in length and need to be cut to varying lengths to meet specific needs.

[0003] When cutting the wire trough, the pre-cut section at the front is suspended in the air, while the remaining section is supported by a bracket. After the front section is cut, the feed mechanism advances the wire trough to cut the next section. For thinner-walled U-shaped wire troughs, the side walls of the U-shaped wire trough have less support force, so during laser cutting, the impact of the laser cutting may cause uneven cuts on both sides of the U-shaped wire trough. At the same time, since the pre-cut section of the wire trough is suspended in the air, the cut of the wire trough may also be deformed under the action of gravity during cutting, affecting the quality of the cut wire trough. Summary of the Invention

[0004] In view of this, the present invention provides a laser cutting device for wire groove processing, which can support the groove edges on both sides of the wire groove incision to ensure the flatness of the wire groove incision.

[0005] To achieve the above objectives, the present invention provides the following technical solutions.

[0006] 1. Laser cutting equipment for wire groove processing, including: a laser cutting mechanism configured to cut the wire groove to form a wire groove cut; The roller support mechanism includes a first roller support portion and a second roller support portion which are arranged opposite to each other on both sides of the wire trough incision, wherein the first roller support portion is used to support the groove edge at the incision of the wire trough main section, and the second roller support portion is used to support the groove edge at the incision of the wire trough cutting section; During the process of cutting the wire groove by the laser cutting mechanism, the first roller support portion and the second roller support portion respectively provide support forces to the groove edges on both sides of the wire groove cut, so that the groove edges on both sides of the wire groove cut are flush.

[0007] The first roller support part and the second roller support part are used to support the groove edges on the left and right sides of the wire groove incision respectively. In this way, during the cutting process of the laser cutting mechanism, the extrusion force of the laser cutting mechanism on the groove edges on both sides of the wire groove incision can be resisted, thereby avoiding the unevenness of the wire groove incision and ensuring the quality of the wire groove cutting section.

[0008] 2. Based on Technical Solution 1, the roller support mechanism also includes: a hinge connection portion connecting the first roller support portion and the second roller support portion; A locking assembly that can lock the hinge connection portion during the wire groove cutting process so that the first roller support portion and the second roller support portion can support both sides of the wire groove cut; Unlock the trigger assembly, unlock the locking assembly after the wire groove is cut, and the second roller support part turns down to allow the wire groove cutting section to slide off.

[0009] 3. On the basis of technical solution 2, the hinged connection part is provided with a locking block, which can flip along with the second roller support part; the locking assembly includes a locking cylinder, which is provided with a locking piston rod, which can extend out of the locking cylinder to abut against the locking block during the wire groove cutting process to prevent the second roller support part from flipping down; the locking piston rod can be retracted into the locking cylinder to disengage from the locking block after the wire groove is cut, so that the second roller support part flips down.

[0010] 4. Based on technical solution 3, the unlocking trigger assembly includes a trigger slider, a first air inlet channel and a second air inlet channel. The trigger slider is installed on the second roller support part and can move up and down. A trigger air channel is provided on the trigger slider. The second air inlet channel is connected to the locking cylinder, and the first air inlet channel is connected to the air source. When the wire groove cutting section presses down the trigger slider due to gravity, the trigger slider moves downward, and the trigger air channel is connected to the first air inlet channel and the second air inlet channel, so that the gas enters the locking cylinder and squeezes the locking piston rod to retract the locking cylinder.

[0011] 5. Based on Technical Solution 3, the roller support mechanism also includes: The power-assisted pushing component can drive the wire trough cutting section to slide outward after the wire trough cutting is completed, so as to accelerate the sliding speed of the wire trough cutting section.

[0012] 6. Based on technical solution 5, the power-assisted pushing component includes a power-assisted roller, a power-assisted fan blade and a power-assisted air pipe. The power-assisted fan blade is installed on one side of the axial direction of the power-assisted roller, and the power-assisted roller contacts and squeezes the inner wall of the wire groove cutting section; the power-assisted air pipe blows air to the power-assisted fan blade, and the power-assisted roller rotates, so that the power-assisted roller drives the wire groove cutting section to move outward.

[0013] 7. Based on Technical Solution 6, the roller support mechanism also includes: The guide positioning assembly includes a lateral positioning wheel and an anti-hanging roller. There are two lateral positioning wheels. The two lateral positioning wheels are rollingly installed on the end of the second roller support part away from the first roller support part. The anti-hanging roller is installed above the two lateral positioning wheels. The two lateral positioning wheels support the groove edges on both sides of the wire groove to position the outward-moving wire groove.

[0014] 8. Based on Technical Solution 1, the first roller support portion and the second roller support portion each include a roller bracket, a support roller, and a locking slider. The support rollers are provided in three groups, and the three groups of support rollers respectively support the three groove edges of the wire groove cutout; each support roller corresponds to a locking slider and can be slidably installed in the roller bracket via the locking slider; The roller support mechanism also includes a roller locking assembly for locking the support roller. During the wire trough feeding process, the roller locking assembly unlocks the support roller so that the support roller can be retracted into the roller bracket after being squeezed by the wire trough.

[0015] 9. Based on technical solution 8, the roller locking assembly includes a locking cylinder and an unlocking elastic member. The locking cylinder is provided with a locking piston rod that can extend or retract into the locking cylinder. The unlocking elastic member is arranged in the locking cylinder and is used to reset the locking piston rod. When air is ventilated into the locking cylinder, the locking piston rod overcomes the elasticity of the unlocking elastic member and extends out of the locking cylinder. The locking piston rod squeezes the locking slider and does not move, thereby locking the support roller. When the locking cylinder is deflated, the unlocking elastic member rebounds, so that the locking piston rod retracts into the locking cylinder and unlocks the support roller.

[0016] 10. Based on technical solution 1, the first roller support part and the second roller support part each include three groups of rotatable support rollers, which respectively support the three groove edges of the wire groove incision, and a gas isolation cover is arranged between the support rollers and the wire groove incision; during the wire groove cutting process, the gas isolation cover ejects air to form an air curtain between the support rollers and the wire groove incision to isolate the welding slag.

DETAILED DESCRIPTION

[0028] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figure 1 and Figure 2The laser cutting equipment for wire groove processing in this embodiment uses the laser emitted by the laser to cut the wire groove 7 to obtain the target length of the wire groove 7 to meet the customer's use needs. It includes a support platform 1, a roller support mechanism 2, a laser cutting mechanism 3, a wire groove feeding mechanism 4, a wire groove clamping mechanism 5 and a discharge chute 6. Figure 1 , the wire trough feeding mechanism 4, the wire trough clamping mechanism 5 and the discharge chute 6 are installed on the support platform 1 in sequence along the feeding direction of the wire trough 7. The wire trough feeding mechanism 4 is used for feeding the wire trough 7 to achieve continuous loading. The wire trough clamping mechanism 5 is used to clamp and flip the wire trough 7 to achieve cutting of different trough edges of the wire trough 7. The laser cutting mechanism 3 is installed on the support platform 1 and is directly above the wire trough incision a, and is used to cut the wire trough 7. The discharge chute 6 is used to receive the cut wire trough cutting section 72. The roller support mechanism 2 is installed on the wire trough clamping mechanism 5, and is used to support the trough edges on both sides of the wire trough incision a. The laser cutting mechanism 3 is started and moves down to the position directly above the cut of the wire trough 7 to be cut and performs the cutting task. After one side of the wire trough 7 is cut, the wire trough clamping mechanism 5 flips the wire trough 7 so that the laser cutting mechanism 3 cuts the other side of the wire trough 7. During the wire trough 7 cutting process, the roller support mechanism 2 always supports the two sides of the wire trough cut a to ensure that the groove edges at the wire trough cut a are flush after cutting. When the wire trough 7 is cut, the cut wire trough section 72 falls into the discharge chute 6 and is transported to the next process. The wire trough feeding mechanism 4 drives the wire trough 7 to feed so that the laser cutting mechanism 3 cuts the next section of the wire trough 7, thereby achieving continuous cutting of the wire trough 7.

[0030] See also Figure 3 The roller support mechanism 2 of this embodiment includes a support cylinder 21, a first roller support portion 22, a second roller support portion 23, and a support link 210. The first roller support portion 22 and the second roller support portion 23 are both disposed within the wire trough 7 and located on either side of the wire trough cutout a. The first roller support portion 22 is used to support the three groove edges on the left side of the wire trough cutout a, namely, the groove edges at the cutout of the wire trough main section 71. The second roller support portion 23 is used to support the three groove edges on the right side of the wire trough cutout a, namely, the groove edges at the cutout of the wire trough cutting section 72. The cylinder body of the support cylinder 21 is mounted on the wire trough clamping mechanism 5. The piston rod of the support cylinder 21 is connected to the support link 210. The support link 210, the first roller support portion 22, and the second roller support portion 23 are connected in sequence. In this way, when the wire trough clamping mechanism 5 flips the wire trough 7, the first roller support portion 22 and the second roller support portion 23 can flip along with the wire trough 7 and continue to provide support for the wire trough 7.

[0031] Among them, see Figure 4 、 Figure 5 and Figure 6The first roller support portion 22 and the second roller support portion 23 each include a roller bracket 221 and three groups of support rollers 222. The roller bracket 221 is provided with first mounting grooves 2211 on both sides and the top side. The three groups of support rollers 222 are respectively installed in the first mounting grooves 2211 of the roller bracket 221. The three groups of support rollers 222 can support the three groove edges of the wire groove 7 respectively. Two support rollers 222 are provided in each group, and the support rollers 222 can rotate, which facilitates the feeding and removal of the wire groove 7. During the cutting process of the wire groove 7, the groove edges on the left and right sides of the wire groove incision a will be subjected to the impact force of the laser cutting mechanism 3. The three groups of support rollers 222 of the first roller support portion 22 and the second roller support portion 23 respectively generate support forces to resist the impact force on the groove edges on the left and right sides of the wire groove incision a, thereby preventing the groove edges of the wire groove incision a from being uneven due to the force, thereby affecting the quality of the wire groove 7. When the wire trough 7 is cut, only the end of the wire trough cutting section 72 at the cut is supported by the second roller support part 23, and the other end of the wire trough cutting section 72 is suspended in the air. At this time, the center of gravity of the wire trough 7 is unstable and it flips down, thereby breaking away from the second roller support part 23 and falling into the discharge trough 6.

[0032] In order to prevent the wire groove cutting section 72 from being stuck in the second roller support portion 23 and unable to be separated normally. Figures 3 to 8 The roller support mechanism 2 of this embodiment further includes a hinge connection 24, a locking assembly 25, and an unlocking trigger assembly 26. The hinge connection 24 connects the first roller support portion 22 and the second roller support portion 23, allowing the second roller support portion 23 to flip freely. The locking assembly 25 is used to lock the hinge connection 24 to prevent the second roller support portion 23 from flipping during the cutting of the wire groove 7. The unlocking trigger assembly 26 is used to unlock the locking assembly 25, allowing the second roller support portion 23 to flip downward after the wire groove 7 is cut, facilitating the sliding of the wire groove cutting section 72.

[0033] Specifically, see Figure 4 、 Figure 6 and Figure 8 The hinge connection part 24 of this embodiment includes a left hinge connection part 241, a right hinge connection part 242, a locking block 243 and a return spring 244. The left hinge connection part 241 is connected to the first roller support part 22, and the right hinge connection part 242 is connected to the second roller support part 23. The left hinge connection part 241 and the right hinge connection part 242 are rotatably connected via a pin shaft, thereby realizing the hinge connection between the first roller support part 22 and the second roller support part 23. Figure 6 and Figure 8, the locking block 243 is installed on the right hinge connection 242, and can be flipped along with the second roller support part 23, and the reset spring 244 is installed between the left hinge connection 241 and the right hinge connection 242, and is used for resetting the left hinge connection 241 and the right hinge connection 242. The locking assembly 25 of this embodiment includes a locking cylinder 251 and an elastic reset member (not shown in the figure). The locking cylinder 251 is installed on the left hinge connection 241. The locking cylinder 251 is provided with a locking piston rod 2511 that can extend or retract the locking cylinder 251. The elastic reset member is installed in the locking cylinder 251 and is used for resetting the locking piston rod 2511. The elastic reset member is preferably a spring. The upper cavity of the locking cylinder 251 is provided with an exhaust hole (not shown in the figure) for exhausting the locking cylinder 251. Combined with Figure 8 and Figure 10The unlocking trigger assembly 26 of this embodiment includes a trigger roller 261, a trigger slider 262, a guide post 263, a return spring 264, a first air inlet channel 265, and a second air inlet channel 266. The trigger roller 261 is rotatably mounted on the top of the trigger slider 262. The roller bracket 221 is provided with a second mounting slot 2212. The trigger slider 262 is slidably mounted within the second mounting slot 2212 of the roller bracket 221 via two guide posts 263. Each guide post 263 is fitted with a return spring 264 to reset the trigger slider 262. The trigger slider 262 is provided with a U-shaped trigger air channel 2621, with both ends located on the inner end surface of the trigger slider 262. One end of the second air inlet channel 266 communicates with the upper chamber of the locking cylinder 251, while the other end extends through the second mounting slot 2212 of the roller bracket 221 and faces the inner end surface of the trigger slider 262. One end of the first air inlet channel 265 is connected to the air source, while the other end extends through the second mounting slot 2212 of the roller bracket 221 and faces the inner end surface of the trigger slider 262. During the wire groove 7 cutting process, the locking piston rod 2511 extends out of the locking cylinder 251 and abuts against the upper end surface of the locking block 243. The second roller support portion 23 and the locking block 243 cannot be turned over due to the position restraint of the locking piston rod 2511. Both the first roller support portion 22 and the second roller support portion 23 support the groove edges on both sides of the wire groove cutout a. After the wire groove 7 is cut, the wire groove cutting section 72 tilts forward under the action of gravity. At this time, the wire groove cutting section 72 squeezes the trigger roller 261, and the trigger roller 261 drives the trigger slider 262 to move downward. When the trigger slider 262 moves down to the right position, the two end ports of the trigger air channel 2621 are respectively opposite to the ports of the first air inlet channel 265 and the second air inlet channel 266. At this time, the trigger air channel 2621 connects the first air inlet channel 265 and the second air inlet channel 266, and continuously ventilates the first air inlet channel 265. The gas enters the upper cavity of the locking cylinder 251 through the trigger air channel 2621 and the second air inlet channel 266. The gas overcomes the elastic force of the elastic return member and squeezes the locking piston rod 2511 to retract the locking cylinder 251. When the locking piston rod 2511 disengages from the upper end surface of the locking block 243, it no longer restricts the second roller support portion 23 and the locking block 243. Under the action of its own gravity, the second roller support portion 23 overcomes the elastic force of the return spring 244 and flips downward. The wire groove cutting section 72 flips downward along with the second roller support portion 23 and accelerates downward under the action of its own gravity, preventing the wire groove cutting section 72 from getting stuck in the second roller support portion 23 and being unable to properly disengage. After the wire groove cutting section 72 disengages from the second roller support portion 23, the return spring 264, under its own rebound force, presses the trigger slider 262 and the trigger roller 261 upward and resets, and the trigger airway 2621 no longer connects to the first air inlet channel 265 and the second air inlet channel 266.At the same time, the return spring 244 squeezes the right hinge connection part 242 to flip and reset under its own restoring force. When the right hinge connection part 242 drives the second roller support part 23 to reset, the elastic return part squeezes the locking piston rod 2511 to extend the locking cylinder 251, and the gas in the upper cavity of the locking cylinder 251 is squeezed out from the exhaust hole, thereby realizing the re-locking of the first roller support part 22 and the second roller support part 23, so that the next section of the wire groove cutting section 72 can be supported.

[0034] Furthermore, in order to speed up the sliding speed of the wire groove cutting section 72, see Figure 8 and Figure 10 The roller support mechanism 2 of this embodiment further includes a power-assisting component 27 , which can drive the wire groove cutting section 72 to slide outward after the wire groove 7 is cut, so as to accelerate the sliding speed of the wire groove cutting section 72 .

[0035] Specifically, see Figure 8 and Figure 10 The power-assisted pushing assembly 27 of this embodiment includes a power-assisted roller, a power-assisted blade 271, and a power-assisted air pipe 272. To reduce the number of rollers and pipes, the power-assisted roller and the trigger roller 261 are identical. The power-assisted blade 271 is mounted on one side of the trigger roller 261 axially. Under the elastic force of the return spring 264, the trigger roller 261 can always contact and press the inner wall of the cable trough 7. One end of the power-assisted air pipe 272 is connected to the trigger air channel 2621, and the other end is aligned with the power-assisted blade 271. When the trigger air channel 2621 is connected to the first air inlet channel 265 and the second air inlet channel 266, the gas introduced into the first air inlet channel 265 flows through the trigger air channel 2621 to the power-assisting air pipe 272, and the power-assisting air pipe 272 blows air to the power-assisting fan blade 271, and the power-assisting fan blade 271 drives the trigger roller 261 to rotate right, and the trigger roller 261 drives the wire groove cutting segment 72 to slide outward through the friction between the trigger roller 261 and the wire groove cutting segment 72, thereby accelerating the sliding speed of the wire groove cutting segment 72 and improving production efficiency.

[0036] Furthermore, in order to avoid the premature triggering of the auxiliary pushing assembly 27 when the wire trough 7 is not cut, causing the wire trough cutting section 72 to deflect to one side, increasing the difficulty of unloading. Figure 4 、 Figure 5 and Figure 6 The roller support mechanism 2 of this embodiment further includes a guide positioning component 28, which can position the moving direction of the wire groove cutting segment 72 to avoid deviation in the angle of the wire groove cutting segment 72.

[0037] Specifically, see Figure 6The guide positioning assembly 28 of this embodiment includes a support block 281, a lateral positioning wheel 282 and an anti-hanging roller 283. The support block 281 is rotatably mounted on one end of the second roller support portion 23 away from the first roller support portion 22. Two lateral positioning wheels 282 are provided. The two lateral positioning wheels 282 are rotatably mounted on both sides of the support block 281 and contact the groove edges on both sides of the wire groove 7. The anti-hanging roller 283 is rotatably mounted between the two lateral positioning wheels 282. During the cutting process of the wire groove 7, if the power-assisting pushing assembly 27 is triggered in advance, the two lateral positioning wheels 282 can position the wire groove 7 to prevent the wire groove 7 from deflecting to one side. When the wire groove 7 is cut and slides down, the anti-hanging roller 283 can prevent the end of the wire groove cutting section 72 from hanging on the support block 281.

[0038] In addition, during the feeding process of the wire groove 7, in order to prevent the support roller 222 from expanding due to heat caused by laser cutting, the resistance to the feeding of the wire groove 7 is increased. Figure 8 and Figure 9 In this embodiment, the support rollers 222 can be squeezed by the wire trough 7 during feeding, and retracted into the first mounting slots 2211 of the roller bracket 221. This prevents the support rollers 222 from exerting a forced squeezing force on the wire trough 7, which could cause deformation of the wire trough 7. The roller support mechanism 2 also includes roller locking assemblies 29, each of which corresponds to a group of support rollers 222. During the cutting process of the wire trough 7, the roller locking assemblies 29 can lock the support rollers 222, allowing them to stably support the two sides of the wire trough cutout a.

[0039] Specifically, see Figure 8 and Figure 9 In this embodiment, a locking slider 223 and a return spring 224 are respectively provided at both ends of the support roller 222. A sliding groove is provided in the roller bracket 221 for the support roller 222 to move in and out. The support roller 222 is slidably connected to the sliding groove of the roller bracket 221 via the locking slider 223. The return spring 224 is installed in the sliding groove to reset the support roller 222. When the wire groove 7 is cut, the wire groove feeding mechanism 4 pushes the wire groove main section 71 forward. The inner wall of the wire groove main section 71 generates an extrusion force on the support roller 222. The support roller 222 overcomes the elastic force of the return spring 224 and retracts into the roller bracket 221, thereby preventing the support roller 222 from generating a forced support force on the wire groove main section 71 and causing the wire groove 7 to deform. Figure 8 and Figure 9The roller locking assembly 29 includes an air intake duct 291, a locking cylinder 292, and an unlocking elastic member 293. The locking cylinder 292 is mounted on one side of the slideway of the roller bracket 221. The locking cylinder 292 is equipped with a locking piston rod 2921 that can be extended or retracted. The unlocking elastic member 293 is disposed within the locking cylinder 292 and is preferably a spring that resets the locking piston rod 2921. One end of the air intake duct 291 is connected to an air source, and the other end is connected to the locking cylinder 292. During the wire groove 7 cutting process, air is supplied to the locking cylinder 292, causing the locking piston rod 2921 to overcome the elastic force of the unlocking elastic member 293 and extend out of the locking cylinder 292. The end of the locking piston rod 2921 presses against the locking slider 223, keeping it stationary. The locking slider 223 then locks the support roller 222, which can stably support the edge of the wire groove cutout a, ensuring a flush cutout a. Before the main section 71 of the wire groove is fed, the locking cylinder 292 is deflated, the unlocking elastic member 293 rebounds and drives the locking piston rod 2921 to retract into the locking cylinder 292. At this time, the locking piston rod 2921 no longer squeezes the locking slider 223, the locking slider 223 and the supporting roller 222 are unlocked, and the supporting roller 222 can retract under the squeezing of the main section 71 of the wire groove.

[0040] In addition, in order to prevent the welding slag from splashing onto the surface of the support roller 222 when the wire groove 7 is cut, causing the rolling resistance of the support roller 222 to be too large and scratching the inner wall of the wire groove 7. Figure 4 、 Figure 5 and Figure 6 In this embodiment, a gas isolation cover 8 is provided between the support roller 222 and the wire groove cutout a. During the wire groove 7 cutting process, the gas isolation cover 8 sprays air and forms an air curtain between the support roller 222 and the wire groove cutout a, so that the welding slag will be isolated by the air curtain to prevent the welding slag from splashing on the support roller 222.

[0041] Specifically, see Figure 4 、 Figure 5 and Figure 6 The gas isolation hood 8 of this embodiment includes two square air tubes 81, which are mounted on the roller brackets 221 of the first roller support portion 22 and the second roller support portion 23, respectively. Each square air tube 81 has closely connected air holes 811 along its extension direction. During the wire slot 7 cutting process, air is continuously ventilated into the two square air tubes 81, and the gas is discharged through the air holes 811, thereby forming an air curtain to isolate the welding slag.

[0042] Since the wire trough 7 needs to be clamped and fed continuously during the processing, in order to achieve continuous processing of the wire trough 7, see Figure 2The wire trough clamping mechanism 5 of this embodiment includes four circumferentially arranged clamping sections 51. Each clamping section 51 is primarily composed of a clamping cylinder 511 and a clamping roller 512. The clamping roller 512 is mounted on the end of the piston rod of the clamping cylinder 511. This design allows the wire trough clamping mechanism 5 to consistently clamp the lead trough 7 without affecting the feeding of the wire trough 7.

[0043] The working process of the present invention is further described below to further demonstrate the working principle and advantages of the present invention: S1, lock the support roller 222: ventilate the locking cylinder 292, the locking piston rod 2921 overcomes the elasticity of the unlocking elastic member 293 and extends out of the locking cylinder 292, and the end of the locking piston rod 2921 squeezes the locking slider 223 to keep the locking slider 223 stationary. At this time, the locking slider 223 locks the support roller 222.

[0044] S2, cutting of the wire groove 7: start the laser cutting mechanism 3, the laser cutting mechanism 3 moves down to the top of the incision of the wire groove 7 to be cut and cuts the wire groove 7. The left and right sides of the wire groove incision a will be subjected to the impact force of the laser cutting mechanism 3. The three groups of supporting rollers 222 of the first roller support part 22 and the second roller support part 23 respectively support the left and right sides of the wire groove incision a to prevent the wire groove incision a from being uneven due to the force. After the groove edge of one side of the wire groove 7 is cut, the wire groove clamping mechanism 5 flips the wire groove 7 so that the laser cutting mechanism 3 cuts the groove edge of the other side of the wire groove 7 until all three groove edges of the wire groove 7 are cut. S3, unloading of the wire groove cutting section 72: After the wire groove 7 is cut, the wire groove cutting section 72 tilts forward under the action of gravity. At this time, the wire groove cutting section 72 squeezes the trigger roller 261 downward, and the trigger roller 261 drives the trigger slider 262 to move downward. When the trigger slider 262 moves down to the right position, the two end ports of the trigger air channel 2621 are respectively opposite to the ports of the first air inlet channel 265 and the second air inlet channel 266. At this time, the trigger air channel 2621 connects the first air inlet channel 265 and the second air inlet channel 266, and continuously ventilates the first air inlet channel 265. The gas enters the upper cavity of the locking cylinder 251 through the trigger air channel 2621 and the second air inlet channel 266. The gas overcomes the elastic force of the elastic reset part and squeezes the locking piston rod 2511 to retract the locking cylinder 251. The locking piston rod 2511 no longer limits the second roller support portion 23 and the locking block 243. Under the action of its own gravity, the second roller support portion 23 overcomes the elastic force of the return spring 244 and flips downward, and the wire groove cutting segment 72 flips downward along with the second roller support portion 23. At the same time, the gas introduced into the first air inlet channel 265 flows through the trigger air channel 2621 into the power-assisting air pipe 272. The power-assisting air pipe 272 blows air to the power-assisting fan blade 271, which drives the trigger roller 261 to rotate clockwise. The friction between the trigger roller 261 and the wire groove cutting segment 72 drives the wire groove cutting segment 72 to slide outward, thereby accelerating the sliding speed of the wire groove cutting segment 72. After separating from the second roller support portion 23, the wire groove cutting segment 72 falls into the discharge chute 6 and is transported to the next process.

[0045] S4, the second roller support 23 is reset: After the wire groove cutting section 72 is separated from the second roller support 23, the return spring 264, under its own resilience, squeezes the trigger slider 262 and the trigger roller 261 upward and resets them, and the trigger air channel 2621 is no longer connected to the first air inlet channel 265 and the second air inlet channel 266. At the same time, the return spring 244, under its own restoring force, squeezes the right hinge connection 242 to flip and reset it. When the right hinge connection 242 is reset, the elastic reset member squeezes the locking piston rod 2511 to extend out of the locking cylinder 251, and the gas in the upper chamber of the locking cylinder 251 is squeezed out from the exhaust hole, thereby achieving the reset of the first roller support 22 and the second roller support 23, so that the next wire groove cutting section 72 can be supported.

[0046] S5, feeding of the main section 71 of the wire trough: the locking cylinder 292 is deflated, the unlocking elastic member 293 rebounds and drives the locking piston rod 2921 to retract into the locking cylinder 292. At this time, the locking piston rod 2921 no longer squeezes the locking slider 223, and the locking slider 223 and the supporting roller 222 are unlocked; the wire trough feeding mechanism 4 drives the main section 71 of the wire trough to feed, and the supporting roller 222 can retract under the squeezing of the main section of the wire trough 71, thereby avoiding the support roller 222 from generating a forced squeezing force on the main section of the wire trough 71 and causing the wire trough 7 to deform; when the wire trough 7 is fed into place, the locking cylinder 292 is continued to be ventilated, and the supporting roller 222 supports both sides of the wire trough incision a, so that the laser cutting mechanism 3 cuts the next section of the wire trough 7.

[0047] It can be seen from this that the laser cutting equipment for processing the wire groove 7 in this embodiment can not only use the roller support mechanism 2 to strongly support the groove edges on both sides of the wire groove cut a during cutting, to ensure the flatness of the wire groove cut a and the quality of the wire groove cut segment 72, but also can accelerate the sliding of the wire groove cut segment 72 and improve processing efficiency.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention 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 invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
