Description

Technical Field

[0001] The present invention relates to the technical field of automated processing, and particularly to an automated production line for arch supports. Background Art

[0002] Section steel is a bar-shaped steel with a certain cross-sectional shape and size, and is one of the four major types of steel (plate, pipe, section, wire). According to the cross-sectional shape, section steel is divided into simple cross-section section steel and complex cross-section section steel (special-shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beam, channel steel, rail, window frame steel, bent section steel, etc.

[0003] In the production process of existing arch-shaped section steel supports, a systematic continuous automated production cannot be formed, continuous feeding cannot be carried out, many processes in the production process still require manual assistance, the degree of automation is not high, the labor intensity of workers is large, the production efficiency is not high, and the demand for short-time large-volume production in the market cannot be met; at the same time, after the arch support is produced and processed, it needs to be manually stacked. This not only has a large workload and high labor intensity, but also reduces the production efficiency of the arch support; and when the arch support is stacked and palletized, it is generally simply stacked on the trolley. When the trolley transports the stacked arch supports, the arch supports are prone to looseness and shaking, affecting the neat stacked state of the arch supports, and it is not convenient for the staff to load, unload and transfer them later.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0020] Example 1: Refer to Figure 1-19 , an automated production line for arched brackets, including a press and a frame 1 distributed along the processing line, further including: A loading conveyor roller path 2, which is arranged at the front end of the frame 1 and is used for conveying steel sections for loading; A moving fixed-length part 3, which is arranged at the end of the loading conveyor roller path 2 and is used for positioning the cutting position of the steel section. A cutting machine is arranged on the side of the moving fixed-length part 3; A stepping transfer part 4, which is arranged on the side of the moving fixed-length part 3 and is perpendicular to the moving fixed-length part 3. It is used to realize the stepping transverse movement of the cut steel section. A first auxiliary conveyor roller path 28 is arranged between the stepping transfer part 4 and the moving fixed-length part 3; A pinch roller mechanism 30, which is arranged at the feeding end of the stepping transfer part 4 and is used for clamping and conveying the steel section. The press is placed on the upper side of the pinch roller mechanism 30. A second auxiliary conveyor roller path 29 is arranged between the pinch roller mechanism 30 and the stepping transfer part 4; A clamping and pulling-out part 5, which is placed at the end of the stepping transfer part 4 and is used for clamping and pulling out the steel section on the pinch roller mechanism 30; A tilting part 6, which is placed at the end of the clamping and pulling-out part 5 and is used for tilting and laying flat the arched and vertically placed steel section due to pressing; A receiving and detecting conveyor roller path 7, which is placed beside the tilting part 6 and is arranged parallel to the tilting part 6; A collecting bench 8, which is arranged at the end of the frame 1 and is used for stacking the steel sections and pushing and translating the neatly stacked steel sections onto the feeding trolley 17.

[0021] Specifically, the feeding conveyor roller table 2 transports a section steel to the moving fixed-length part 3, and the plasma cutting machine (the cutting machine is a prior art) cuts according to the adjusted section steel trajectory. After cutting, the first auxiliary conveyor roller table 28 transports the cut section steel to the stepping transfer part 4. The stepping transfer part 4 repeatedly transports the cut section steel to the second auxiliary conveyor roller table 29 according to the stepping rhythm. When the section steel reaches the pinch roller mechanism 30, the pinch roller mechanism 30 clamps and feeds the section steel into the press die, and the press starts to press down to press the section steel. Since the length of the section steel is greater than the length of the die, it needs to be pressed three times to be formed. When the pinch roller mechanism 30 feeds the material for the second time and the third time, the pinch roller is not sufficient for feeding conditions, and it is necessary to cooperate with the clamping and pulling-out part 5 to pull out the remaining part. The clamping and pulling-out part 5 clamps the completed arched steel support and pulls it out of the press die and pulls it to the tipping part 6. The tipping part 6 tips and lays flat the section steel that is arched and standing upright due to pressing. The receiving and detecting roller table 7 receives and conveys the laid-flat arched steel support, and detects it during the conveying process of the arched steel support. The qualified arched steel support is fed to the collecting bench 8 for stacking. The neatly stacked arched steel supports are pushed to the feeding trolley 17 by the stepping transfer method. The feeding trolley 17 transports the arched steel support outside the site and is unloaded manually. After unloading, the feeding trolley 17 is manually controlled to return to the collecting station.

[0022] In this application, by reasonably arranging the production process of the steel arch frame 19 and through various automatic mechanisms, the continuous conveying and processing of the section steel are realized, so that the section steel raw material is processed into an arched support. It has a high degree of automation, reduces the labor intensity of workers, reduces the waste of raw materials, has a high production efficiency, and has good practicability.

[0023] Embodiment 2: Refer to Figure 1-3 , an automatic operation production line for an arched support. On the basis of Embodiment 1, further, the structures of the first auxiliary conveyor roller table 28, the second auxiliary conveyor roller table 29, the feeding conveyor roller table 2, and the receiving and detecting roller table 7 are the same. The first auxiliary conveyor roller table 28, the second auxiliary conveyor roller table 29, the feeding conveyor roller table 2, and the receiving and detecting roller table 7 all include a first bench seat 9 fixed on the frame 1. A plurality of conveyor roller bodies 901 are rotatably connected to the first bench seat 9. A sprocket 902 is arranged at the end of each conveyor roller body 901. A chain 903 is also arranged between the plurality of sprockets 902. A base 10 is fixed on one side of the first bench seat 9. A conveyor motor 1001 is arranged on the base 10. Synchronous pulleys 1002 are arranged on the conveyor motor 1001 and one of the conveyor roller bodies 901 respectively. A synchronous belt is arranged between the two synchronous pulleys 1002.

[0024] Specifically, when the roller table is working, the conveying motor 1001 is controlled to operate. The output shaft of the conveying motor 1001 drives one of the conveying roller bodies 901 on the first frame seat 9 through a synchronous pulley 1002 and a synchronous belt. During the rotation of the conveying roller body 901, other conveying roller bodies 901 are driven through a sprocket 902 and a chain 903, thereby realizing the conveying and transfer of the profiled steel.

[0025] Embodiment 3: Refer to Figure 1-3 , an automated production line for arch supports. On the basis of Embodiment 2, further, a detection component 904 is further provided on the first frame seat 9 of the receiving and detecting roller table 7. The detection component 904 includes a laser sensor and a laser camera, and the laser sensor and the laser camera are electrically connected to the background terminal.

[0026] Specifically, when the profiled steel pressed into an arch support is conveyed on the receiving and detecting roller table 7, the pressed workpiece is scanned and detected by a laser or infrared detection instrument, and the calculation result is compared and analyzed with the drawing parameters of the workpiece through a formula. The background terminal finally determines whether the pressed profiled steel is qualified.

[0027] Embodiment 4: Refer to Figure 4-5 , an automated production line for arch supports. On the basis of Embodiment 3, further, the moving and sizing part 3 includes a second frame seat 11 fixed on the frame 1 and arranged in parallel with the first frame seat 9 of the feeding and conveying roller table 2. A scale 111 and a moving motor 112 are fixed on the second frame seat 11. A first lead screw 113 connected to the output shaft of the moving motor 112 is rotatably connected to the second frame seat 11. A nut seat 114 is threadedly connected to the first lead screw 113. A hydraulic lifting arm 115 is fixed on the top of the nut seat 114, and a limit stop 116 is arranged on the hydraulic lifting arm 115.

[0028] Specifically, according to the size and length of the profiled steel to be cut, the moving motor 112 is controlled to operate. The output shaft of the moving motor 112 drives the first lead screw 113 to rotate. When the first lead screw 113 rotates, the nut seat 114 threadedly connected to the outer side thereof drives the hydraulic lifting arm 115 to move along its axis. The hydraulic lifting arm 115 moves to the end of the profiled steel and the limit stop 116 is controlled to move down to limit the end of the profiled steel to ensure the stop position of the profiled steel. Then, the cutting machine is controlled to cut the profiled steel at the dimension corresponding to the scale 111.

[0029] Embodiment 5: Refer to Figure 6, An automated production line for arched supports. Further, on the basis of Embodiment 4, the step transfer part 4 includes a third pedestal 12 fixedly arranged on the frame 1 and perpendicular to the second pedestal seat 11. A positioning baffle 121 opposite to the moving sizing part 3 is fixedly arranged on the side of the third pedestal 12. A transfer oil cylinder 122 is fixedly arranged on the third pedestal 12. The piston rod of the transfer oil cylinder 122 is connected with a pushing cross beam frame 123. The pushing cross beam frame 123 slides on the third pedestal 12. A number of first pawls 124 that are movably abutted against the profiled steel are arranged on each cross beam of the pushing cross beam frame 123. A first torsion spring is arranged between the first pawl 124 and the cross beam of the pushing cross beam frame 123.

[0030] Specifically, after the profiled steel is cut, the hydraulic lifting arm 115 lifts the limit block 116, and the profiled steel is continuously conveyed and conveyed to the third pedestal 12 by the second auxiliary conveying roller path 29 until its movement is restricted by the positioning baffle 121 on the third pedestal 12. When the transfer oil cylinder 122 works, it controls its piston rod to pull the pushing cross beam frame 123 back and forth. The pushing cross beam frame 123 step-conveys the profiled steel on the third pedestal 12 by relying on the first pawl 124. When the pushing cross beam frame 123 moves back, the first pawl 124 is resisted by the profiled steel subsequently conveyed to the third pedestal 12, and the first pawl 124 is forced to flip to avoid the profiled steel. When the pushing cross beam frame 123 continues to push, the first pawl 124 resets and continues to push the profiled steel placed on the third pedestal 12.

[0031] Embodiment 6: Refer to Figure 7 、 Figure 8 、 Figure 9 and Figure 18 , An automated production line for arched supports. Further, on the basis of Embodiment 5, the clamping and pulling-out part 5 includes a fourth pedestal 13 fixedly arranged on the frame 1. A transverse movement motor 131 is fixedly arranged on the fourth pedestal 13. The output shaft of the transverse movement motor 131 is connected with a first screw rod 132 that is rotatably connected to the fourth pedestal 13. A first sleeve 133 is threadedly connected to the first screw rod 132. A transverse movement frame 134 that is slidably connected to the fourth pedestal 13 is fixedly arranged on the first sleeve 133. A longitudinal movement motor 135 is fixedly arranged on the transverse movement frame 134. The output shaft of the longitudinal movement motor 135 is connected with a second screw rod 136 that is rotatably connected to the transverse movement frame 134. A second sleeve 137 is threadedly connected to the second screw rod 136. A longitudinal movement frame 138 that is slidably connected to the transverse movement frame 134 is fixedly arranged on the second sleeve 137. A rotary motor 139 is fixedly arranged on the longitudinal movement frame 138. The output shaft of the rotary motor 139 is connected with a rotary seat 14. A clamping member is arranged on the rotary seat 14.

[0032] Further, the clamping member includes clamping cylinders 141 fixedly arranged on both sides of the rotating base 14. A connecting plate 142 is connected to the piston rod of each clamping cylinder 141. A clamping claw 143 is arranged at the end of the connecting plate 142. A guiding rod 144 is fixedly arranged on the rotating base 14, and the connecting plate 142 is slidably connected to the guiding rod 144.

[0033] Further, the pinch roller mechanism 30 includes a sixth pedestal 3001 fixedly arranged on the frame 1. An upper bearing seat 3002 and a lower bearing seat 3003 are arranged on the sixth pedestal 3001. A conveying wheel 3004 is rotatably connected in both the upper bearing seat 3002 and the lower bearing seat 3003. A driving motor 3005 for driving the conveying wheel 3004 in the lower bearing seat 3003 is fixedly arranged on the sixth pedestal 3001. A hydraulic cylinder 3006 for driving the upper bearing seat 3002 to lift is fixedly arranged on the sixth pedestal 3001. A lifting cylinder 3007 is fixedly arranged on the sixth pedestal 3001, and a pneumatic baffle 3008 is connected to the piston rod of the lifting cylinder 3007.

[0034] Specifically, the hydraulic cylinder 3006 drives the upper bearing seat 3002 to move to adjust the distance between the two conveying wheels 3004. The lifting cylinder 3007 drives the pneumatic baffle 3008 to move, which plays a role in positioning the incoming material in place and aligning the heads, limits the end of the profiled steel, controls the operation of the driving motor 3005, so that the driving motor 3005 drives the conveying wheel 3004 on the lower bearing seat 3003 to rotate, and cooperates with the conveying wheel 3004 in the upper bearing seat 3002 to convey the profiled steel. When the profiled steel reaches the pinch roller mechanism 30, the conveying wheel 3004 clamps and feeds the profiled steel into the press die (the press is a prior art). The press starts to press down to press the profiled steel. Since the length of the profiled steel is greater than the length of the die, it needs to be pressed three times to be formed. When the pinch roller feeds the material for the second time and the third time, the pinch roller no longer meets the feeding conditions, and it is necessary to cooperate with the clamping and pulling-out part 5 to pull out the remaining part for pressing. According to different radii of the profiled steel, the grabbing points are different. Control the transverse movement motor 131 and the longitudinal movement motor 135 to work, so that the clamping member on the rotating base 14 moves to the designated position to grab the profiled steel. The clamping claw 143 is in the open state, and then control the clamping cylinder 141 to work, so that the clamping cylinder 141 drives the clamping claw 143 to clamp and pull the profiled steel through the connecting plate 142. The guiding rod 144 can improve the stability of the connecting plate 142 when it moves. Subsequently, control the transverse movement motor 131 to work, so that the first sleeve 133 moves along the axial direction of the first screw rod 132, and then cooperate with the press to pull out the remaining part of the profiled steel for pressing. Then, the clamping claw 143 clamps the pressed steel arch 19 and disengages it from the die through the flipping angle. The clamping claw 143 pulls the pressed steel arch 19 out to the tipping part 6 through the feeding movement.

[0035] Example 7: Refer to Figure 10-12, An automated production line for arch supports. Further, on the basis of Embodiment 6, the tilting part 6 includes a fifth pedestal 15 fixed on the frame 1. A tilting oil cylinder 151 is arranged on the fifth pedestal 15. The piston rod of the tilting oil cylinder 151 is movably connected to a tilting frame 16. The tilting frame 16 is rotationally connected to the fifth pedestal 15 through a pin shaft. The tilting frame 16 includes a connecting seat 161 rotationally connected to the fifth pedestal 15, a transverse seat 162 fixedly connected to the connecting seat 161, a plurality of vertical plates 163 fixed on the transverse seat 162, and a support plate 164 arranged on the vertical plates 163.

[0036] Specifically, after the clamping and pulling-out part 5 moves the pressed steel arch support 19 to the tilting part 6, the steel arch support 19 is placed on the support positions of the vertical plates 163 and the support plates 164 on the transverse seat 162. Subsequently, the tilting oil cylinder 151 is controlled to operate. The tilting oil cylinder 151 drives the transverse seat 162 to flip around the pin shaft connected to the fifth pedestal 15 through the connecting seat 161, so that the vertically placed steel arch support 19 lies flat on the receiving and detecting roller table 7.

[0037] Embodiment 8: Refer to Figure 13-14 , An automated production line for arch supports. Further, on the basis of Embodiment 7, the collecting pedestal 8 is arranged beside the end of the receiving and detecting roller table 7. A limiting plate that abuts against the section steel movably is fixed at the end of the first pedestal 9 of the receiving and detecting roller table 7. The collecting pedestal 8 includes collecting seats 801 and pushing seats 802 fixed on both sides of the receiving and detecting roller table 7. Pushing oil cylinders 803 are fixed on both the collecting seats 801 and the pushing seats 802. A pushing plate 8031 is fixed on the piston rod of the pushing oil cylinder 803. A second claw 8032 is rotationally connected to the pushing plate 8031 through a pin shaft. A second torsion spring for the second claw 8032 to reset and rotate is sleeved on the pin shaft.

[0038] Specifically, after the receiving and detecting roller table 7 finishes detecting the steel arch support 19 during transportation, the steel arch support 19 continues to move until it reaches the end of the receiving and detecting roller table 7 and is limited by the limiting plate. At this time, the pushing oil cylinder 803 on the pushing seat 802 works, and the section steel moved to the end of the receiving and detecting roller table 7 is pushed one by one to the collecting seat 801 for stacking. After a certain number of steel arch supports 19 are stacked on the collecting seat 801, the pushing oil cylinder 803 on the collecting seat 801 is controlled to work. The pushing oil cylinder 803 uses the second claw 8032 on the pushing plate 8031 to horizontally push the neatly stacked steel arch support 19 to the feeding trolley 17.

[0039] Embodiment 9: Refer to Figure 15, An automated production line for arched supports. Further, on the basis of Embodiment 8, it further includes a walking track 18 provided on one side of the collection bench 8. A feeding trolley 17 slides on the walking track 18. On the side of the top of the feeding trolley 17 away from the collection bench 8, a side plate 171 is fixedly provided. On the side of the feeding trolley 17 away from the side plate 171, a groove 172 is provided. A limiting block 173 is slidably connected in the groove 172. An extrusion inclined surface is provided on the side of the limiting block 173 close to the collection bench 8. A first elastic element 174 is provided between the limiting block 173 and the inner wall of the groove 172.

[0040] Specifically, during the process of pushing the steel arched support 19 from the collection bench 8 onto the feeding trolley 17, the steel arched support 19 exerts a thrust on the extrusion inclined surface of the limiting block 173. The limiting block 173 contracts into the groove 172 under the force to avoid the movement of the steel arched support 19 until one side of the neatly stacked steel arched support 19 abuts against the side plate 171, and the other side crosses the limiting block 173. The limiting block 173 is reset under the push of the first elastic element 174 and cooperates with the side plate 171 to limit the other side of the steel arched support 19, preventing the neatly stacked steel arched support 19 from loosening due to shaking during the movement of the feeding trolley 17 along the walking track 18, thereby ensuring the neatly stacked state of the steel arched support 19.

[0041] Embodiment 10: Refer to Figure 16-17 , An automated production line for arched supports. Further, on the basis of Embodiment 8, a receiving groove 20 is provided on the limiting block 173. A first rotating rod 21 is fixedly provided in the receiving groove 20. A first torsion spring is provided between the first rotating rod 21 and the limiting block 173. A first swinging plate 22 is rotatably connected to the outside of the first rotating rod 21. A second rotating rod 23 is rotatably connected to the first swinging plate 22. A second torsion spring is provided between the second rotating rod 23 and the first swinging plate 22. A second swinging plate 24 is fixedly provided on the second rotating rod 23. An angle limiting component is provided at the position of the second swinging plate 24 and the first swinging plate 22.

[0042] Further, the angle limiting component includes a rubber pad 25 fixedly provided on the second swinging plate 24. A cavity 251 is provided in the rubber pad 25. Two pneumatic cavities 26 are provided on the first swinging plate 22. The cavity 251 and the pneumatic cavities 26 are connected by air pipes. A piston body 261 is slidably connected in each pneumatic cavity 26. A second elastic element 262 is fixedly provided on the piston body 261. One end of the second elastic element 262 away from the piston body 261 is connected to a limiting rod 263 that is slidably connected to the first swinging plate 22. A number of limiting holes 264 that are circular and cooperate with the limiting rod 263 are provided on both the first rotating rod 21 and the second rotating rod 23.

[0043] Specifically, initially, the second swing plate 24 is in the same plane with the first swing plate 22 under the action of the second torsion spring, and the first swing plate 22 is tilted with the limit block 173 under the action of the first torsion spring. When the limit block 173 moves down and enters the groove 172, the first swing plate 22 moves down synchronously and is pressed by the side wall of the groove 172. The first swing plate 22 drives the second swing plate 24 to move into the accommodating groove 20. After the stacked steel arch frame 19 passes over the limit block 173 and abuts against the side plate 171, the limit block 173 moves upward under the elastic force of the first elastic element 174, and the first swing plate 22 resets and swings under the action of the first torsion spring. During this period, the second swing plate 24 at the upper end of the first swing plate 22 will abut against the steel arch frame 19, and the second swing plate 24 will abut against the steel arch frame 19 through the rubber pad 25 at the end. The air squeezed in the internal cavity 251 is introduced into the two pneumatic chambers 26 of the first swing plate 22 through the air pipe. The piston bodies 261 in the two pneumatic chambers 26 are pushed by the air. The piston body 261 drives the limiting rod 263 to move through the second elastic element 262, so that the limiting rods 263 in the two pneumatic chambers 26 are respectively inserted into the limiting holes 264 of the first rotating rod 21 and the second rotating rod 23, so as to achieve the position fixation between the first swing plate 22 and the first rotating rod 21, and the position fixation between the first swing plate 22 and the second rotating rod 23, thereby maintaining the second swing plate 24 at this time. The abutment state of the steel arch frame 19 is prevented, and when the feeding trolley 17 moves along the walking track 18 to feed materials, the neatly stacked steel arch frames 19 are prevented from loosening due to shaking during movement, thereby ensuring the neat stacking state of the steel arch frames 19, which is convenient for the subsequent operation of the staff.

[0044] Example 11: Reference Figure 16-17 , an arch bracket automated production line, based on Example 8, further, a pull rope 27 is fixed on the limit rod 263, and one end of the pull rope 27 away from the limit rod 263 passes through the first swing plate 22 and extends outward, and the pull rope 27 is placed in the rodless cavity of the pneumatic cavity 26.

[0045] Specifically, when it is necessary to release the movement restriction on the steel arch frame 19, the staff only needs to pull the pull rope 27 so that the pull rope 27 pulls the limit rod 263, and the limit rod 263 squeezes the second elastic element 262 and shrinks into the pneumatic cavity 26, so that the limit rod 263 releases the movement restriction between the second rotating rod 23 and the first swing plate 22, and then moves the second swing plate 24 to make the second swing plate 24 away from the steel arch frame 19, so as to facilitate the removal of the steel arch frame 19.
