Description

Technical Field

[0001] This invention relates to the field of cable tray cutting technology, and more specifically, to a cable tray cutting platform and a cutting method thereof. Background Technology

[0002] Cable trays are important structural components composed of key parts such as supports, covers, and connecting accessories. Their main function is to support and lay various cables. They are widely used in power engineering, communication engineering, and industrial automation. In actual laying and installation, in order to adapt to the specific dimensions and wiring requirements of the construction site, the cable trays often need to be precisely cut to ensure that they can perfectly fit the installation requirements of different sites.

[0003] According to patent document CN118616799A, a cable tray cutting platform is disclosed, including a workbench and a punching mechanism. The punching mechanism includes a bracket mounted on a support base, a base at the bottom of the bracket, a hydraulic cylinder on the upper part of the bracket, a sliding plate connected to the lower part of the hydraulic cylinder, a blade holder fixedly connected to the lower part of the sliding plate, and a blade mounted on the lower part of the blade holder. The base has outer top plates on both sides, the inner surface of which abuts against the outer surface of the cable tray. The blade holder has sleeves symmetrically arranged on both sides, with telescopic rods fitted inside the sleeves. A second spring is provided at the upper end of the telescopic rod, and inner support blocks are provided on both sides of the lower part of the telescopic rod, with the outer end face of the inner support block flush with the inner surface of the cable tray. This invention, by providing outer top plates on both sides of the base to support the outer surface of the cable tray and inner support blocks on both sides of the blade to support the inner surface of the cable tray, avoids deformation during cable tray cutting and ensures the quality of cable tray cutting.

[0004] When processing cable trays, the flat patch is usually placed on the processing platform and shaped by step punching. Then the excess is cut off. However, traditional cutting equipment usually only supports the outer side of the cable tray when cutting, and lacks the limiting and fixing of the inner side wall. During the cutting process, the impact force of the tool may cause the cut of the cable tray to be concave and deformed inward, which not only affects the flatness of the cut, but also damages the structural stability of the cable tray. Subsequent additional shaping and correction processing is required, which greatly reduces the processing efficiency. Summary of the Invention

[0015] In addition, the present invention also relates to a cutting method for a cable tray cutting platform, comprising the following steps: Step 1: Pre-processing of sheet material feeding: Pass the raw sheet material to be processed through the through groove of the rectangular plate and insert it into the gap between the two conveyor rollers to complete the feeding. Adjust the position of the sheet material to make it parallel to the conveying direction to complete the feeding positioning. Step 2: Automatic conveying of sheet metal: Start the motor, and the motor drives the horizontal convex transmission rod to rotate. The horizontal convex transmission rod drives the fourth transmission disc, the columnar transmission crossbar, the second gear, the first gear, and the bottom conveyor roller transmission rod to rotate in sequence through the third track. Then, the transmission disc and the track drive the top conveyor roller transmission rod to rotate synchronously. The two conveyor rollers rotate in opposite directions, driving the sheet metal to be conveyed at a uniform speed to the punching station. Step 3: Plate reciprocating flatness correction: During the rotation of the transverse convex transmission rod, the second track drives the columnar rotating crossbar, the columnar rotating crossbar and the tapered blocks at both ends to rotate synchronously. The rotation of the tapered blocks, combined with the elastic force of the spring, pushes the columnar push-pull rod to drive the push-pull plate to move back and forth periodically along the guide groove of the side plate. When the push-pull plate moves forward, the inclined surface of the abutment pushes the abutment block down, driving the columnar push-pull rod down along the slide block. Through the pressure roller connecting block, the pressure roller moves downward, rolling the plate that has passed the top of the step punch plate segment by segment to correct the flatness of the plate and remove the stress deformation of the plate. Step 4: Plate punching and bending positioning: After the plate is completely conveyed to the top of the punching tray, turn off the conveying power and start the electric push rod to push the H-shaped lower pressure plate downward. The H-shaped lower pressure plate drives the L-shaped lifting plates on both sides to slide down along the inner wall of the guide block, compressing the third spring to accumulate the reset elastic force. During the downward movement of the L-shaped lifting plate, the rotating rod hinge block moves down synchronously. The rotating rod hinge block pushes the rotating rod to rotate, which in turn pushes the expansion side rod and expansion side plate to move outward. The expansion side plate drives the columnar transverse push rod to move outward. The columnar push block at the end of the columnar transverse push rod pushes the flipping block to flip inward, finally driving the convex side pressure plate to rotate upward, punching and bending the left and right edges of the plate to ninety degrees and pressing it. At the same time, the L-shaped lifting plate drives the bottom I-shaped pressure plate to move downward, pressing down and fixing it from the top of the middle of the plate. Together with the convex side pressure plates on both sides, the overall punching and positioning locking of the cable tray is completed. Step 5: Sheet material limiting conveying and cutting: After the step punch positioning is completed, the sheet material lock is released, and the processed bridge tray blank is pushed forward to move the part to be cut to the middle area of ​​the concave guide plate. During the conveying process, the two cutting wheels are always in close contact with the two sides of the sheet material under the elastic force of the fourth spring. The expansion and contraction positions are automatically adjusted according to the width of the sheet material to maintain the contact and limiting of the sheet material edge. The cutting tool cuts along the gap between the two cutting wheels to complete the straight and regular fixed length cutting operation. Step Six: Unloading and Resetting: After cutting, control the electric push rod to retract, and the third spring releases its elastic force to drive the L-shaped lifting plate, H-shaped lower pressure plate, I-shaped pressure plate and side pressure positioning structure to reset as a whole. The convex side pressure plate and I-shaped pressure plate release the processed workpiece, and the finished cable tray can be taken out to complete the entire processing process.

[0016] The beneficial effects of this invention are as follows: This invention, by setting up a feeding rack and a processing platform, realizes the periodic automatic flatness correction during the conveying of sheet metal, the synchronous internal and external clamping and fixing during step punching and bending, and the internal and external bidirectional support and limiting of the cable tray cut position during the cutting process, effectively solving the problem of inward concave deformation of the cut caused by the impact force of the tool during the traditional cutting process. On the one hand, the periodic reciprocating downward pressure of the pressure roller during the conveying process can correct the flatness of the sheet material before the step punching, avoid the warping of the sheet material caused by storage or transportation affecting the subsequent processing accuracy, reduce the shape error caused by the unevenness of the sheet material during the step punching and shaping process, and improve the initial processing qualification rate of the cable tray. On the other hand, the structure of moving the H-shaped lower pressure plate downwards and driving the convex side pressure plate upwards to squeeze, while punching and bending the edge of the plate to ninety degrees, directly presses and fixes it from the inner wall of the bent cable tray. With the top pressing down of the middle I-shaped pressure plate, it achieves synchronous fixation in multiple positions inside and outside, avoiding the displacement of the plate edge during the step punching and shaping process. It does not require additional manual adjustment of the fixing position, which greatly improves the efficiency and shape accuracy of step punching. Furthermore, during the cutting process, the two cutting wheels remain in close contact with the inner and outer sides of the cable tray to be cut. This not only guides the cutting tool but also provides synchronous support and restraint to the inner and outer walls of the cut, offsetting the impact force when the cutting tool descends. This prevents the cut from deforming inward due to the impact force, ensuring the flatness of the cut and protecting the structural stability of the cable tray after cutting. No additional shaping or correction processing is required afterward, further improving the overall processing efficiency of the cable tray and reducing the processing cost of subsequent finishing.

On one hand, the transverse convex transmission rod 1124 drives the fourth transmission disc 1131 to rotate through the third track 1130, which in turn drives the columnar transmission crossbar 1118 and the second gear 1119 to rotate. The second gear 1119 meshes with and drives the gear 118 to rotate. The gear 118 carries... The bottom conveyor roller transmission rod 115 rotates, and the bottom conveyor roller transmission rod 115 drives the top conveyor roller transmission rod 115 to rotate synchronously through the transmission disc 117 and the crawler 119. The two conveyor rollers 116 rotate in coordination to convey the plate forward. On the other hand, the transverse convex transmission rod 1124 drives the second transmission disc 1127 to rotate through the second crawler 1125. The second transmission disc 1127 drives the columnar rotating crossbar 1126 and the conical abutments 1128 at both ends to rotate. As the conical abutments 1128 rotate, they push the two columnar push-pull rods 16 forward. The movement, coordinated with the rotation of spring 18 and conical abutment block 1128, enables the columnar push-pull rod 16 to drive the push-pull plate 110 to periodically reciprocate along the side upright plate guide groove 13. When the push-pull plate 110 moves forward, the chamfered surface of the abutment plate 111 and the abutment block 1115 come into contact, and the abutment plate 111 pushes the abutment block 1115 down along the chamfered surface, causing the columnar push-pull rod 1113 to slide down along the slide block 1112. This, in turn, drives the pressure roller 1117 to move downward through the pressure roller connecting block 1116, conveying the material to the top of the step punch plate 21116. The top of the sheet metal is stamped to correct its flatness again. When the push-pull plate 110 moves backward to reset, the abutment plate 111 disengages from the abutment block 1115. The second spring 1114 releases its elastic potential energy to drive the columnar push-pull rod 1113 to reset upward. The pressure roller 1117 rises simultaneously to release the pressure on the sheet metal, ensuring that the sheet metal can be conveyed forward normally. This cycle repeats. After each conveying cycle, the pressure roller 1117 will press and correct the sheet metal once to prevent the sheet metal from warping due to its own deformation, which would affect the subsequent processing and cutting accuracy.

Cutting wheels 238 are rotatably connected to the tops of both sets of left and right cutting wheel connecting blocks 237. When the sheet metal is fully conveyed to the top of the punching support plate 21116, the electric push rod 222 is activated to move the H-shaped lower pressure plate 223 downward. As the H-shaped lower pressure plate 223 moves, it causes the L-shaped lifting plates 224 on both sides to slide downward along the inner wall of the guide block 215, compressing the third spring 226 and accumulating reset force. Simultaneously, as the L-shaped lifting plates 224 move downward, they also drive the rotating rod hinge block 21121 connected to their outer side to move downward. When the rod moves downward, it pushes the rotating rod 21120 to rotate, which in turn pushes the retractable side rod 21119 and the retractable side plate 21118 connected to it to move outward. The retractable side plate 21118 drives the columnar transverse push rod 21111 to move outward. The columnar push block 21112 at the end of the columnar transverse push rod 21111 slides in the hinge block groove 2119 and the inverted L-shaped groove block 21113, pushing the flipping block 21114 to flip inward, and finally driving the convex side pressure plate 21115 to rotate upward. The extrusion process presses the left and right edges of the sheet metal to a 90-degree angle and clamps them in place. At the same time, the L-shaped lifting plate 224 moves the bottom I-shaped pressure plate 227 downwards, pressing it down again from the middle of the top of the sheet metal. This, combined with the convex side pressure plates 21115 on both sides, completes the overall shape of the cable tray sheet metal through punching and positioning. After the sheet metal is positioned, the punched sheet metal is pushed forward, moving the part of the sheet metal to be cut to the middle of the concave guide plate 231. During the movement, the two cutting wheels 238 will be pressed against the two sides of the sheet metal by the elastic force of the fourth spring 234, automatically adjusting their opening and closing positions according to the width of the sheet metal to maintain the fit and limit of the sheet metal edges. When cutting, the cutting blade cuts down along the gap between the two cutting wheels 238 to complete the neat cutting operation. After the cutting is completed, the electric push rod 222 retracts, the third spring 226 releases its elastic force to drive the overall structure to reset, and the convex side pressure plate 21115 and the I-shaped pressure plate 227 release the sheet metal, allowing the processed cable tray workpiece to be removed.

[0023] In addition, the present invention also relates to a cutting method for a cable tray cutting platform, comprising the following steps: Step 1: Pre-processing of sheet material feeding: Pass the original sheet material to be processed through the through groove 14 of the rectangular plate 11 and insert it into the gap between the two conveying rollers 116 to complete the feeding. Adjust the position of the sheet material to make it parallel to the conveying direction to complete the feeding positioning. Step 2: Automatic conveying of sheet metal: Start motor 1123. Motor 1123 drives the horizontal convex transmission rod 1124 to rotate. The horizontal convex transmission rod 1124 drives the fourth transmission disc 1131, the columnar transmission crossbar 1118, the second gear 1119, the first gear 118, and the bottom conveyor roller transmission rod 115 to rotate in sequence through the third track 1130. Then, through the transmission disc 117 and the track 119, the top conveyor roller transmission rod 115 rotates synchronously. The two conveyor rollers 116 rotate in opposite directions, driving the sheet metal to be conveyed at a uniform speed to the punching station. Step 3: Plate reciprocating flatness correction: During the rotation of the transverse convex transmission rod 1124, the second track 1125 drives the columnar rotating crossbar 1126, the columnar rotating crossbar 1126 and the tapered blocks 1128 at both ends to rotate synchronously. The rotation of the tapered blocks 1128, in conjunction with the elastic force of the spring 18, pushes the columnar push-pull rod 16 to drive the push-pull plate 110 to move back and forth periodically along the side plate guide groove 13. When the push-pull plate 110 moves forward, the inclined surface of the abutment plate 111 pushes the abutment block 1115 down, driving the columnar push-pull rod 1113 down along the slide block 1112. Through the pressure roller connecting block 1116, the pressure roller 1117 moves downward, rolling the plate that has passed the top of the step punch plate 21116 segment by segment to correct the flatness of the plate and remove the stress deformation of the plate. Step 4: Sheet metal bending and positioning: After the sheet metal is fully conveyed to the top of the bending support plate 21116, turn off the conveying power and start the electric push rod 222 to push the H-shaped lower pressure plate 223 downward. The H-shaped lower pressure plate 223 drives the L-shaped lifting plates 224 on both sides to slide down along the inner wall of the guide block 215, compressing the third spring 226 to accumulate the reset elastic force. During the downward movement of the L-shaped lifting plate 224, it drives the rotating rod hinge block 21121 to move down synchronously. The rotating rod hinge block 21121 pushes the rotating rod 21120 to rotate, which in turn pushes the expansion and contraction side rod 21119 and the expansion and contraction side plate 211129. 118 moves outward, the expanding side plate 21118 drives the columnar transverse push rod 21111 to move outward, the columnar push block 21112 at the end of the columnar transverse push rod 21111 pushes the flipping block 21114 to flip inward, and finally drives the convex side pressure plate 21115 to rotate upward, punching and bending the left and right edges of the plate to ninety degrees and pressing it. At the same time, the L-shaped lifting plate 224 drives the bottom I-shaped pressure plate 227 to move downward, pressing down and fixing it from the top of the middle of the plate. Together with the two convex side pressure plates 21115, the overall step punching and positioning locking of the cable tray is completed. Step 5: Plate limiting conveying and cutting: After the step punch positioning is completed, the plate locking is released, and the processed bridge tray blank is pushed forward to move the part to be cut to the middle area of ​​the concave guide plate 231. During the conveying process, the two cutting wheels 238 are always in close contact with the two sides of the plate under the elastic force of the fourth spring 234. The expansion and contraction positions are automatically adjusted according to the width of the plate to maintain the contact and limiting of the plate edge. The cutting tool cuts along the gap between the two cutting wheels 238 to complete the straight and regular fixed length cutting operation. Step Six: Unloading and Resetting: After cutting, control the electric push rod 222 to retract, and the third spring 226 releases its elastic force to drive the L-shaped lifting plate 224, H-shaped lower pressure plate 223, I-shaped pressure plate 227 and side pressure positioning structure to reset as a whole. The convex side pressure plate 21115 and I-shaped pressure plate 227 release the processed workpiece, and the finished cable tray can be taken out to complete the entire processing process.

[0024] The working principle of this invention is as follows: During the forming process of cable trays, the required sheet material is first passed through the through-slot 14 in the rectangular plate 11 to the inner side of the two conveyor rollers 116. Then, the motor 1123 is started. The rotation of the motor 1123 drives the transverse convex transmission rod 1124 to rotate synchronously. On one hand, the transverse convex transmission rod 1124 drives the fourth transmission disc 1131 to rotate via the third track 1130, which in turn drives the columnar transmission crossbar 1118 and the second gear 1119 to rotate. The second gear 1119 meshes with and drives the gear 118 to rotate. The gear 118 drives the bottom conveyor roller transmission rod 115 to rotate. The bottom conveyor roller transmission rod 115 drives the top conveyor roller transmission rod 115 to rotate synchronously via the transmission disc 117 and the track 119. The two conveyor rollers... 116, in conjunction with rotation, conveys the plate forward. Meanwhile, the transverse convex transmission rod 1124 drives the second transmission disc 1127 to rotate via the second track 1125. The second transmission disc 1127 drives the columnar rotating crossbar 1126 and the conical abutments 1128 at both ends to rotate. As the conical abutments 1128 rotate, they push the two columnar push-pull rods 16 forward. Combined with the rotation of the spring 18 and the conical abutments 1128, the columnar push-pull rods 16 drive the push-pull plate 110 to periodically reciprocate along the side plate guide groove 13. When the push-pull plate 110 moves forward, the chamfered surface of the abutment plate 111 contacts the abutment block 1115. The abutment plate 111 pushes the abutment block 1115 down along the chamfered surface, causing the columnar push-pull rod 1113 to move along the slide block 111. 2. Slide downwards, and then drive the pressure roller 1117 downwards via the pressure roller connecting block 1116, pressing the top of the sheet material conveyed to the top of the step punching plate 21116, and correcting the flatness of the sheet material again. When the sheet material is completely conveyed to the top of the step punching plate 21116, the electric push rod 222 is activated to drive the H-shaped lower pressure plate 223 downwards. When the H-shaped lower pressure plate 223 moves, it will drive the L-shaped lifting plates 224 on both sides to slide downwards along the inner wall of the guide block 215, compressing the third spring 226 to accumulate the reset elastic force. At the same time, during the downward movement of the L-shaped lifting plate 224, it will synchronously drive the rotating rod hinge block 21121 connected to its outer side to move downwards. When the rotating rod hinge block 21121 moves downwards, it will push the rotating rod 21120 to rotate, and then... The expansion and retraction side rod 21119 and the connected expansion and retraction side plate 21118 are pushed outward. The expansion and retraction side plate 21118 drives the columnar transverse push rod 21111 to advance outward. The columnar push block 21112 at the end of the columnar transverse push rod 21111 slides in the hinge block groove 2119 and the inverted L-shaped groove block 21113, pushing the flipping block 21114 to flip inward. Finally, the convex side pressure plate 21115 rotates upward and squeezes, pressing the left and right edges of the plate to ninety degrees and fixing it. At the same time, the L-shaped lifting plate 224 drives the bottom I-shaped pressure plate 227 to move downward, pressing down again from the middle position of the top of the plate to fix it. Together with the convex side pressure plates 21115 on both sides, the overall shape of the cable tray plate is completed by punching and positioning.After the plate is positioned, the plate, which has been punched, is pushed forward, moving the part of the plate to be cut to the center of the concave guide plate 231. During the movement, the two cutting wheels 238, under the elastic force of the fourth spring 234, are pressed tightly against the two edges of the plate, automatically adjusting their opening and closing positions according to the width of the plate to maintain contact and limit with the edges of the plate. During cutting, the cutting blade cuts along the gap between the two cutting wheels 238, thus completing a neat cut. After cutting, the electric push rod 222 retracts, the third spring 226 releases its elastic force, driving the overall structure to reset. The convex side pressure plate 21115 and the I-shaped pressure plate 227 release the plate, allowing the processed cable tray workpiece to be removed.

6. The cutting method of a cable tray cutting platform according to claim 5, characterized in that: Includes the following steps: Step 1: Pre-processing of plate feeding: Pass the original plate to be processed through the through groove (14) of the rectangular plate (11) and insert it into the gap between the two conveying rollers (116) to complete the feeding. Adjust the position of the plate to make it parallel to the conveying direction to complete the feeding positioning. Step 2: Automatic conveying of sheet metal: Start the motor (1123). The motor (1123) drives the horizontal convex transmission rod (1124) to rotate. The horizontal convex transmission rod (1124) drives the fourth transmission disc (1131), the columnar transmission crossbar (1118), the second gear (1119), the first gear (118), and the bottom conveyor roller transmission rod (115) to rotate in sequence through the third track (1130). Then, through the transmission disc (117) and the track (119), the top conveyor roller transmission rod (115) rotates synchronously. The two conveyor rollers (116) rotate in opposite directions, driving the sheet metal to be conveyed at a uniform speed to the punching station. Step 3: Plate reciprocating flatness correction: During the rotation of the transverse convex transmission rod (1124), the second track (1125) drives the columnar rotating crossbar (1126), the columnar rotating crossbar (1126) and the conical blocks (1128) at both ends to rotate synchronously. The rotation of the conical blocks (1128) cooperates with the elastic force of the spring (18) to push the columnar push-pull rod (16) to drive the push-pull plate (110) along the side plate guide groove (13). The push-pull plate (110) moves forward periodically back and forth. When the push-pull plate (110) moves forward, the inclined surface of the abutment plate (111) pushes the abutment block (1115) down, which drives the columnar push-pull upright (1113) down along the slide block (1112). Through the pressure roller connecting block (1116), the pressure roller (1117) moves down and rolls the plate passing the top of the step punch plate (21116) segment by segment to correct the flatness of the plate and remove the stress deformation of the plate. Step 4: Plate bending and positioning: After the plate is completely conveyed to the top of the step bending support plate (21116), turn off the conveying power and start the electric push rod (222) to push the H-shaped lower pressure plate (223) downward. The H-shaped lower pressure plate (223) drives the two L-shaped lifting plates (224) to slide down along the inner wall of the guide block (215), compressing the third spring (226) to accumulate the reset elastic force. During the downward movement of the L-shaped lifting plate (224), it drives the rotating rod hinge block (21121) to move down synchronously. The rotating rod hinge block (21121) pushes the rotating rod (21120) to rotate, thereby pushing the expansion and retraction side rod (21119) and the expansion and retraction side plate. (21118) Move outward, the expansion side plate (21118) drives the columnar transverse push rod (21111) to move outward, the columnar push block (21112) at the end of the columnar transverse push rod (21111) pushes the flipping block (21114) to flip inward, and finally drives the convex side pressure plate (21115) to rotate upward, punching and bending the left and right edges of the plate to ninety degrees and pressing it. At the same time, the L-shaped lifting plate (224) drives the bottom I-shaped pressure plate (227) to move downward, pressing down and fixing from the top of the middle of the plate, and cooperating with the two convex side pressure plates (21115) to complete the overall step punching and positioning locking of the cable tray; Step 5: Plate limiting conveying and cutting: After the step punch positioning is completed, the plate locking is released, and the processed bridge blank is pushed forward to move the part to be cut to the middle area of ​​the concave guide plate (231). During the conveying process, the two cutting wheels (238) are always close to the two sides of the plate under the elastic force of the fourth spring (234). The expansion and contraction positions are automatically adjusted according to the width of the plate to maintain the fit and limit of the plate edge. The cutting tool cuts along the gap between the two cutting wheels (238) to complete the straight and regular fixed length cutting operation. Step Six: Unloading and Resetting: After cutting, control the electric push rod (222) to retract, and the third spring (226) releases its elastic force to drive the L-shaped lifting plate (224), H-shaped lower pressure plate (223), I-shaped pressure plate (227) and side pressure positioning structure to reset as a whole. The convex side pressure plate (21115) and I-shaped pressure plate (227) release the processed workpiece, and the finished cable tray can be taken out to complete the entire processing process.
