Abstract
Description
Technical Field
[0001] This utility model relates to an automated production line, and more particularly to an automated production line for connecting boiler shell and lining with Y-shaped clamps. Background Technology
[0002] Y-shaped catch studs are components used to connect integral refractory linings, precast components, fiber felt, and furnace shells. Their main function is to fix the lining connected to the furnace shell to resist static loads, thermal stress, mechanical rotation, or vibration. Y-shaped catch studs are made by cutting steel strips. The existing manufacturing method involves using multiple presses to assemble different molds and manually feeding the flat steel strips, which are then punched, cut, and split by the presses. This manual feeding and separate manual control method has drawbacks such as low work efficiency, high labor intensity, and serious raw material loss, resulting in high energy and equipment costs for the production plant. Overcoming these problems has become a difficult issue that the production plant needs to solve. Summary of the Invention
[0003] This utility model provides an automated production line for Y-type catch studs used to connect boiler shell and lining, which solves the technical problems of low manufacturing efficiency, high labor intensity and serious raw material loss of existing Y-type catch studs.
[0004] This utility model solves the above technical problems through the following technical solution:

Steel strip coils are mounted on the support, and steel strip conveying rollers are spaced apart on the processing table. Roller drive sprockets are located at the ends of the conveying rollers. A servo drive motor is mounted on the ground between the support and the processing table, and a drive sprocket is connected to the output shaft of the servo drive motor. A ring drive chain is positioned between the drive sprocket and the roller drive sprockets. Inter-roller drive chains are positioned between adjacent conveying rollers. The ends of the flat steel strips on the coils pass sequentially from left to right through the conveying rollers. The processing table is located on the right side of the conveying table. On the table, from left to right, punching and transverse cutting dies, bifurcation separation dies, and longitudinal cutting dies are arranged in sequence. The flat steel strip being conveyed passes through the punching and transverse cutting dies, bifurcation separation dies, and longitudinal cutting dies in sequence.

[0006] The punching tool and the cross-cutting tool are arranged on the bottom surface of the tool mounting base in the left and right directions. The punching tool is arranged on the left side and the cross-cutting tool is arranged on the right side. After the punching tool is stamped and fitted with the punching and cross-cutting die, it punches three equally spaced holes on the clamped flat steel strip.
[0007] After the longitudinal cutting tool and the longitudinal cutting die are stamped together, the longitudinal cutting edge is punched out between the three punch holes.
[0008] After the forked splitting cutter and the forked splitting die are stamped together, the ends of the clamped flat steel strip are separated into a Y-shape along the longitudinal cutting edge.

Steel strip coils 2 are mounted on the steel strip coil support 1. Steel strip conveying rollers 5 are spaced apart on the steel strip conveying processing table 4, with upper and lower rollers clamping flat steel strips 3. Rotation of the rollers enables automatic left-right conveying of the flat steel strips 3. Roller drive sprockets 9 are located at the ends of the steel strip conveying rollers 5. A servo drive motor 7 is mounted on the ground between the steel strip coil support 1 and the steel strip conveying processing table 4. An active drive mechanism is connected to the output shaft of the servo drive motor 7. A sprocket 8 is connected to a drive chain 10 between the drive sprocket 8 and the roller drive sprocket 9. An inter-roller drive chain 6 is connected between adjacent steel strip conveying rollers 5. A servo drive motor 7 drives each steel strip conveying roller 5 on the steel strip conveying processing table 4 to rotate via the sprocket 10, thereby completing the automatic conveying of the flat steel strip 3 on the steel strip conveying processing table 4. The ends of the flat steel strip 3 on the steel strip coil 2 pass sequentially from left to right through each steel strip conveying roller 5. Punches are sequentially arranged on the right side of the steel strip conveying processing table 4 from left to right. The flat steel strip 3 is sequentially conveyed through the punching and transverse cutting die 17, the bifurcation splitting die 18, and the longitudinal cutting die 19. A punching and transverse cutting press 11 is positioned directly above the punching and transverse cutting die 17. A tool mounting seat 14 is positioned on the downward telescopic head of the punching and transverse cutting press 11. A punching tool 20 and a transverse cutting tool 21 are respectively positioned on the lower bottom surface of the tool mounting seat 14. A bifurcation splitting press 19 is positioned directly above the bifurcation splitting die 18. 12. A forked cutting tool 15 is provided on the downward telescopic head of the forked punch 12, and a longitudinal cutting punch 13 is provided directly above the longitudinal cutting die 19. A longitudinal cutting tool 16 is provided on the downward telescopic head of the longitudinal cutting punch 13. The corresponding punch tools cooperate with the die below to realize punching, transverse cutting and longitudinal cutting of the flat steel strip 3. Transverse cutting refers to the cutting edge being set to cut along the left and right direction, and longitudinal cutting refers to the cutting edge being set to cut along the front and back direction. The punching and transverse cutting punch 11, the forked punch 12 and the longitudinal cutting punch 13 are all controlled by hydraulic cylinders.
[0016] The punching cutter 20 and the cross-cutting cutter 21 on the lower bottom surface of the tool mounting base 14 are arranged in the left and right directions. The punching cutter 20 is arranged on the left side of the lower bottom surface of the tool mounting base 14, and the cross-cutting cutter 21 is arranged on the right side of the lower bottom surface of the tool mounting base 14. After the punching cutter 20 is stamped and fitted with the punching and cross-cutting die 17, it punches three equally spaced holes 23 on the clamped flat steel strip 3.
[0017] After the longitudinal cutting tool 16 is stamped and fitted with the longitudinal cutting die 19, a longitudinal cutting edge 24 is punched out between the three punch holes 23.
[0018] After the forked splitting cutter 15 and the forked splitting die 18 are stamped together, the longitudinal cutting edge 24 at the end of the clamped flat steel strip 3 is split open, making it into a Y-shape.
[0019] After the punching tool 20 and the cross-cutting tool 21 are stamped and fitted with the punching and cross-cutting die 17, the formed Y-shaped grab nail 22 is separated from the flat steel strip 3, and at the same time, a second set of punches 25 is punched out at the left end of the flat steel strip 3 at the separation point.
[0020] The following is in conjunction with the appendix Figure 3 The automated production process of the Y-type grappling nail 22 is described in detail below:
[0021] First, place the end 27 of the steel strip coil 2 between the two steel strip conveying rollers 5 at the leftmost end of the steel strip conveying processing table 4. Start the servo drive motor 7, which drives the steel strip conveying rollers 5 to rotate, conveying the end 27 of the flat steel strip 3 on the steel strip coil 2 from left to right. At the same time, the steel strip coil 2 rotates, following the rightward conveying of the end 27 of the flat steel strip 3, releasing the flat steel strip 3. When the end 27 passes through the punching and transverse cutting die 17, the servo drive motor 7 stops. The program in the controller controls the downward telescopic head of the punching and transverse cutting punch 11 to punch downward. The punching cutter 20 punches three holes 23 at the end of the flat steel strip 3. At the same time, the transverse cutting cutter 21 cuts a transverse cut 26 at the end of the flat steel strip 3. After cutting off the end 27 on the right side of the three punches 23, the punching cutter 20 and the transverse cutting cutter 21 are lifted upward.
[0022] The servo drive motor 7 is restarted, and the flat steel strip 3 continues to be conveyed to the right. When the end of the flat steel strip 3 with three punches 23 is conveyed to the underside of the longitudinal cutting punch 13, the servo drive motor 7 stops. The program in the controller controls the downward extension head of the longitudinal cutting tool 16 to punch downward, punching out the longitudinal cutting edge 24 along the direction of the three punches 23, cutting the end of the flat steel strip 3 into two halves along the direction of the three punches 23.
[0023] The servo drive motor 7 is started in reverse, and the flat steel strip 3 is conveyed from right to left in reverse. When the ends of the flat steel strip 3, which have been cut into two halves, are conveyed to the bottom of the forked punch 12, the servo drive motor 7 stops. The program in the controller controls the downward telescopic head of the forked cutter 15 to punch downward. The forked cutter 15 cooperates with the forked die 18 to fork the ends of the flat steel strip 3 into a forked body 27 with one half facing upward and the other half facing downward.
[0024] The servo drive motor 7 is restarted in reverse, and the flat steel strip 3 is conveyed from right to left. When the left side of the end of the flat steel strip 3 with the forked body 27 is conveyed back to directly below the control punching and cross-cutting punch 11, the servo drive motor 7 stops. The program in the controller controls the punching cutter 20 and the cross-cutting cutter 21 to punch down, punch out the second set of punches 25 on the flat steel strip 3, and cut out the transverse cut 26. The end with the forked body 27 on the right side of the transverse cut 26 is cut off from the flat steel strip 3 to form the formed Y-shaped grab nail 22. After the Y-shaped grab nail 22 falls, it enters the material box, and the punching cutter 20 and the cross-cutting cutter 21 are lifted up.
[0025] The servo drive motor 7 is started in the forward direction, and the flat steel strip 3 with the second set of punches 25 is conveyed from left to right. When it is conveyed to the bottom of the longitudinal cutting punch 13, the servo drive motor 7 stops. The above process is repeated to complete the processing of the second Y-shaped gripper 22. The above process is repeated so that the flat steel strip 3 on the steel strip roll 2 is conveyed to the steel strip conveying processing table 4 in sequence, and the Y-shaped gripper 22 is automatically processed and formed.
[0026] The time relay, in conjunction with the servo drive motor 7, controls the forward and reverse rotation of the steel strip to achieve the effect of adjusting the forward and backward movement of the steel strip. Based on the forward and reverse rotation time, the length of the Y-shaped gripper is precisely controlled. Infrared sensors are installed next to the hydraulic cylinders of the punching and cross-cutting punch 11, the forking punch 12, and the longitudinal cutting punch 13, which output switch signals based on the forward and backward movement of the steel strip. The hydraulic system receives the signals from the sensors and relays, and controls the lifting and lowering movements of the cylinders of the punching and cross-cutting punch 11, the forking punch 12, and the longitudinal cutting punch 13 according to the process requirements, thereby realizing the punching, longitudinal cutting, forking, and cutting processes of the flat steel strip.
