Description

A method and apparatus for manufacturing a cable tray Technical Field

[0001] This invention relates to the field of cable tray manufacturing technology, specifically to a method and apparatus for manufacturing cable trays. Background Technology

[0002] Cable trays are rigid structural systems that closely support cables, consisting of straight sections, bends, tees, and crosses in trough, tray, or ladder configurations, as well as brackets and hangers. They can be categorized into ladder-type cable trays, tray-type cable trays, trough-type cable trays, long-span cable trays, and combined cable trays. They can support, protect, and manage cables and are widely used in power, metallurgy, chemical, construction, and public utility projects. Different types and specifications of cable trays are used in different scenarios.

[0003] Depending on the application scenario, cable trays often require curved structures during manufacturing. When assembling curved cable trays, cold-rolled steel plates that have been punched and bent are typically welded at the bends. In practice, these cold-rolled steel plates are usually first cold-pressed and punched, then transported to a painting station for anti-corrosion paint application, and finally transported to a bending station for bending. This process is quite cumbersome, resulting in low overall manufacturing efficiency. Therefore, we propose a cable tray manufacturing method and apparatus to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a method and apparatus for manufacturing cable trays to solve the problems mentioned in the background art.

A bearing is fixedly mounted on the side of the rotating seat away from the guide belt. A rotating cylinder is fixedly mounted in the middle of the bearing.

[0008] As a preferred embodiment of the present invention, a U-shaped rotating frame is fixedly installed at the end of the inner sliding shaft away from the limiting cylinder.

The ball bearings in the rotating mechanism corresponding to the bending area position contact the reduction-pitch diagonal bar. The ball bearings in the rotating mechanism corresponding to the unloading area position contact the second U-shaped rod.

[0012] As a preferred embodiment of the present invention, the adjusting mechanism includes two symmetrically distributed guide slides, which are fixedly installed on the top of the base. Two symmetrically distributed guide slide seats are slidably engaged on the top of each guide slide. A mounting base is fixedly installed on the top of the guide slide seats on the same side of both guide slides. Adjusting longitudinal frames are fixedly installed at both ends of each guide slide. Double-ended screws are rotatably installed on the top of each of the two adjusting longitudinal frames. The double-ended screws are threaded into the middle of the two mounting bases. A pulley drive assembly is fixedly sleeved on the ends of the two double-ended screws. The pulley drive assembly includes two pulleys and a drive belt movably sleeved on the outside of the two pulleys. The pulleys are respectively fixedly sleeved on the ends of the corresponding double-ended screws. A second motor is fixedly installed on the top of one of the adjusting longitudinal frames, and the drive end of the second motor is coaxially fixedly installed with the end of the corresponding double-ended screw.

[0013] As a preferred embodiment of the present invention, the material guiding mechanism is fixedly installed at the bottom end of the material guiding side frame and the top end of the corresponding mounting base frame.

[0014] A method for manufacturing a cable tray includes the following steps:

[0015] Step 1: Adjust the distance between the two guiding mechanisms according to the different widths of cold-rolled steel sheets, control the start of the second motor, and use the belt pulley transmission group to drive the double-headed screws on both sides to rotate synchronously, drive the two mounting bases to move towards each other or away from each other, drive the two guiding mechanisms to move towards each other or away from each other, thereby flexibly adjusting the distance between the two guiding mechanisms to adapt to the processing of cold-rolled steel sheets of different widths.

[0016] Step 2: Control the start of the first motor to drive the transmission gear to rotate the crown gear, thereby driving the corresponding guide shaft and guide wheel to rotate, which in turn drives the guide belt to drive, thereby driving multiple rotating and stationary mechanisms to drive synchronously, and automatically transporting from the feeding area A1 to the processing area A2, bending area A3 and unloading area A4 in sequence.

[0017] Step 3: When the rotating mechanism moves to the feeding area A1, the first U-shaped rod abuts against the ball bearing, placing the cold-rolled steel plate between the positioning plate and the positioning frame. The electric telescopic rod is activated to drive the positioning plate to move, clamping and positioning the cold-rolled steel plate.

[0018] Step 4: The cold-rolled steel sheet is moved to processing area A2. The positioning crossbar abuts against the ball bearing, and the rotating gear and transmission rack mesh. As the rotating mechanism and the cold-rolled steel sheet continue to be transported, the transmission rack drives the transmission rack to rotate, which in turn drives the rotating cylinder to rotate, drives the inner sliding shaft to rotate synchronously, and drives the U-shaped rotating frame and the cold-rolled steel sheet that is clamped and positioned to rotate, so that the cold-rolled steel sheet transported to processing area A2 can be rotated and dried by the spraying mechanism and the drying mechanism.

[0019] Step 5: After processing, the cold-rolled steel sheet is moved to the bending area A3. The reduction-pitch diagonal bar abuts against the ball bearings, and the annular slide limits the rotation of the rotating gear to prevent it from rotating on its own. As the rotating mechanism continues to transmit power, the reduction-pitch diagonal bar drives the ball bearings and limiting cylinders in the rotating mechanism on both sides of the material guide mechanism to move towards each other. This, in turn, drives the inner sliding shaft rods in the rotating mechanism on both sides of the material guide mechanism to slide towards each other in the rotating cylinder, automatically bending the cold-rolled steel sheet between them. At the same time, the positioning frame rotates on one side of the U-shaped rotating frame, and the torsion spring is compressed.

[0020] Step Six: After the cold-rolled steel sheet is automatically bent, it is moved to the unloading area A4. The second U-shaped rod abuts against the ball bearing, keeping the automatically bent cold-rolled steel sheet in a bent state, making the bending process more thorough until the cold-rolled steel sheet is bent into shape. Then, the electric telescopic rod is activated again to drive the positioning plate to move in the opposite direction. The cold-rolled steel sheet loses its clamping and positioning and is automatically unloaded from the rotating mechanism.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. By setting up a material guiding mechanism, and using multiple turning and bending mechanisms, the cold-rolled steel sheet is clamped and positioned, and multiple cold-rolled steel sheets are automatically transported from the feeding area A1 to the processing area A2, bending area A3 and unloading area A4 for feeding, automatic rotary spraying, drying, automatic bending and unloading.

[0023] 2. By setting an adjustable distance mechanism, the two guiding mechanisms can be driven to move towards each other or away from each other, thereby flexibly adjusting the distance between the two guiding mechanisms to adapt to the processing of cold-rolled steel plates of different widths, thus improving the flexibility of the entire device.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example: As shown in Figures 1-11, the present invention provides a cable tray manufacturing apparatus, including a base 1. A spacing adjustment mechanism 2 is fixedly installed at the top of the base 1. Two symmetrically distributed material guiding mechanisms 3 are fixedly installed at the top of the spacing adjustment mechanism 2. Each material guiding mechanism 3 is provided with a plurality of uniformly distributed rotating mechanisms 4. The manufacturing apparatus is divided into a feeding area A1, a processing area A2, a bending area A3, and a unloading area A4, for feeding, processing, bending, and unloading cold-rolled steel plates for cable tray manufacturing. A processing mechanism 5 is fixedly installed at the top of the base 1 at the processing area A2. The processing mechanism 5 is specifically a spraying mechanism and a drying mechanism. The spraying mechanism and the drying mechanism perform anti-corrosion paint spraying and drying processing on the cold-rolled steel plates. A bending mechanism 6, which works in conjunction with the rotating mechanisms 4, is fixedly installed on the opposite side of the material guiding mechanism 3.

[0039] The adjusting mechanism 2 includes two symmetrically distributed guide slides 21, which are fixedly installed on the top of the base 1. Two symmetrically distributed guide slide seats 22 are slidably engaged on the top of each guide slide 21. Mounting bases 23 are fixedly installed on the top of the guide slide seats 22 on the same side of each guide slide 21, facilitating sliding. Adjusting longitudinal frames 24 are fixedly installed at both ends of each guide slide 21. Double-ended screws 25 are rotatably installed on the top of each of the two adjusting longitudinal frames 24. The double-ended screws 25 are threaded into the middle of the two mounting bases 23. Rotation of the double-ended screws 25 on both sides drives the two... The mounting base 23 can move towards each other or away from each other. The ends of the two double-headed screws 25 are fixedly fitted with a pulley drive assembly 26. The pulley drive assembly 26 includes two pulleys and a drive belt that is movably fitted around the outside of the two pulleys. The pulleys are respectively fixedly fitted around the ends of the corresponding double-headed screws 25. A second motor 27 is fixedly installed at the top of one of the adjustable longitudinal frames 24. The drive end of the second motor 27 is coaxially fixedly installed with the end of the corresponding double-headed screw 25. In use, the second motor 27 is turned on and, in conjunction with the drive of the pulley drive assembly 26, synchronously drives the double-headed screws 25 on both sides to rotate.

[0040] The material guiding mechanism 3 includes a material guiding side frame 31. The material guiding mechanism 3 is fixedly installed through the bottom end of the material guiding side frame 31 and the top end of the corresponding mounting base 23. By moving the two mounting bases 23 towards each other or away from each other, the two material guiding mechanisms 3 can be driven to move towards each other or away from each other, thereby flexibly adjusting the distance between the two material guiding mechanisms 3 to adapt to the processing of cold-rolled steel plates of different widths, thereby improving the flexibility of the entire device.

[0041] The two ends of the guide side frame 31 are rotatably mounted with guide shafts 32. The ends of the guide shafts 32 are fixedly mounted with guide wheels 33. Guide belts 34 are movably sleeved on the outer sides of the two guide wheels 33. A crown gear 35 is fixedly mounted on one end of the guide shaft 32 away from the guide wheel 33. A first motor 36 is fixedly mounted on the side of the guide side frame 31 near the crown gear 35. A transmission gear 37 is fixedly mounted on the drive end of the first motor 36. The transmission gear 37 and the crown gear 35 are meshed and connected. In use, the first motor 36 is turned on to drive the transmission gear 37 to rotate the crown gear 35, thereby driving the corresponding guide shaft 32 and guide wheel 33 to rotate, and then driving the guide belt 34 to perform transmission, which facilitates the automatic transportation of multiple cold-rolled steel plates in the subsequent process. The cold-rolled steel plates are automatically transported from the feeding area A1 to the processing area A2, bending area A3 and unloading area A4 in sequence.

[0042] The rotating mechanism 4 includes a rotating seat 41, which is fixedly installed on the outside of the guide belt 34. The guide belt 34 drives the multiple rotating mechanisms 4 to drive synchronously.

[0043] A bearing 42 is fixedly mounted on the side of the rotating seat 41 away from the guide belt 34. A rotating cylinder 43 is fixedly mounted in the middle of the bearing 42. The rotating cylinder 43 is easy to rotate. An inner sliding shaft 44 is movably inserted in the middle of the rotating cylinder 43. A sliding strip 431 is integrally formed on the inner wall of the rotating cylinder 43. A sliding groove 441 is opened on the outer wall of the inner sliding shaft 44 to cooperate with the sliding strip 431. The sliding strip 431 is movably engaged in the corresponding sliding groove 441, which facilitates the inner sliding shaft 44 to slide in the rotating cylinder 43. When the rotating cylinder 43 rotates, it drives the inner sliding shaft 44 to rotate synchronously. A limiting cylinder 45 is fixedly sleeved on one end of the inner sliding shaft 44. A first spring 451 is provided between the limiting cylinder 45 and the rotating cylinder 43. The first spring 451 is movably sleeved on the outside of the inner sliding shaft 44. When the inner sliding shaft 44 slides in the rotating cylinder 43, it compresses the first spring 451, and the first spring 451 contracts.

[0044] A U-shaped rotating frame 46 is fixedly installed at one end of the inner sliding shaft 44 away from the limiting cylinder 45. A positioning frame 47 is movably engaged on the side of the U-shaped rotating frame 46 away from the inner sliding shaft 44. A positioning plate 471 is slidably engaged on the side of the positioning frame 47 away from the U-shaped rotating frame 46. An electric telescopic rod 472 is fixedly installed on the side of the positioning frame 47 away from the U-shaped rotating frame 46. The driving end of the electric telescopic rod 472 extends into the positioning frame 47. The driving end of the electric telescopic rod 472 and the positioning plate 471 are fixedly installed. Protective pads 473 are fixedly installed between the positioning plate 471 and the inner wall of the positioning frame 47. When the rotating mechanism 4 moves to the feeding area A1, the cold-rolled steel plate is placed between the positioning plate 471 and the positioning frame 47. The electric telescopic rod 472 is activated to drive the positioning plate 471 to move, clamping and positioning the cold-rolled steel plate, thereby improving the stability of subsequent transportation, rotation, and bending processing.

[0045] When the inner sliding shaft 44 rotates, it drives the U-shaped rotating frame 46 and the cold-rolled steel plate that is clamped and positioned to rotate, thereby facilitating the rotary spraying and drying of the cold-rolled steel plate transported to the processing area A2 through the spraying mechanism and the drying mechanism, further improving the processing effect of the cold-rolled steel plate.

[0046] When the rotating mechanism 4 and the processed cold-rolled steel sheet move to the unloading area A4, the electric telescopic rod 472 is activated again to drive the positioning plate 471 to move in the opposite direction. The cold-rolled steel sheet loses its clamping and positioning and is automatically unloaded from the rotating mechanism 4.

[0047] A rotating shaft 48 is fixedly inserted into the side of the positioning frame 47 near the U-shaped rotating frame 46. A rotating outer cylinder 481 that cooperates with the rotating shaft 48 is fixedly installed on the side of the U-shaped rotating frame 46 near the positioning frame 47. Two rotating outer cylinders 481 are symmetrically distributed. The two ends of the rotating shaft 48 extend into the rotating outer cylinder 481 respectively. A torsion spring 482 is provided between the end of the rotating shaft 48 and the inner wall of the corresponding rotating outer cylinder 481. By setting the rotating shaft 48, the positioning frame 47 can rotate on one side of the U-shaped rotating frame 46. At the same time, the torsion spring 482 is compressed, which facilitates the subsequent rotation and reset of the positioning frame 47 between the U-shaped rotating frames 46.

[0048] A rotating gear 49 is fixedly installed at one end of the rotating cylinder 43 near the limiting cylinder 45. An annular slide 492, which cooperates with the rotating gear 49, is provided on the outer side of the guide side frame 31. The rotating gear 49 is slidably engaged with the outer side of the annular slide 492, which limits the rotation of the rotating gear 49 to prevent it from rotating on its own. A first frame 493 is fixedly installed on the inner side of the annular slide 492, and the first frame 493 is fixedly installed on the outer side of the guide side frame 31. The annular slide 492 at the processing area A2 is equipped with a transmission rack 491 that works with the rotating gear 49. The rotating gear 49 and the transmission rack 491 are meshed in the rotating mechanism 4 corresponding to the processing area A2. When the rotating mechanism 4 and the cold-rolled steel plate move to the processing area A2, the rotating gear 49 and the transmission rack 491 mesh. As the rotating mechanism 4 and the cold-rolled steel plate continue to transport, the transmission rack 491 drives the transmission rack 491 to rotate, thereby driving the rotating cylinder 43 to rotate on its own.

[0049] The bending mechanism 6 includes a positioning crossbar 61 and a reducing angle diagonal bar 62. Each of the positioning crossbar 61 and the reducing angle diagonal bar 62 has two symmetrically distributed vertically. The two positioning crossbars 61 are located at the processing area A2, and the two reducing angle diagonal bars 62 are located at the bending area A3. The reducing angle diagonal bars 62 in the two bending mechanisms 6 have an eight-shaped structure. The positioning crossbar 61 and the corresponding reducing angle diagonal bar 62 are fixedly installed. A second frame 65 is fixedly installed on the inner side of both the positioning crossbar 61 and the reducing angle diagonal bar 62. The second frame 65 is fixedly installed on the side end of the guide side frame 31.

[0050] The first U-shaped rod 63 is fixedly installed at the end of the positioning crossbar 61 away from the reduction distance inclined rod 62. The first U-shaped rod 63 is located in the feeding area A1. The second U-shaped rod 64 is fixedly installed at the end of the reduction distance inclined rod 62 away from the positioning crossbar 61. The second U-shaped rod 64 is located in the unloading area A4.

[0051] The limiting cylinder 45 is provided with a rolling ball 452 on the side away from the inner sliding shaft rod 44, which works in conjunction with the positioning crossbar 61, the reduction pitch inclined bar 62, the first U-shaped rod 63, and the second U-shaped rod 64. The ball 452 in the rotating mechanism 4 corresponding to the feeding area A1 is in contact with the first U-shaped rod 63. When the rotating mechanism 4 is transported to the feeding area A1, the first U-shaped rod 63 abuts against the ball 452.

[0052] In the rotating mechanism 4 at the location of processing area A2, the ball 452 and the positioning crossbar 61 are in contact. When the rotating mechanism 4 is transported to processing area A2, the positioning crossbar 61 abuts against the ball 452.

[0053] At the bending zone A3, the ball bearing 452 and the reducing angle rod 62 in the rotating mechanism 4 come into contact. When the rotating mechanism 4 is transported to the bending zone A3, the reducing angle rod 62 abuts against the ball bearing 452. As the rotating mechanism 4 continues to drive, the reducing angle rod 62 drives the ball bearing 452 and the limiting cylinder 45 in the rotating mechanism 4 on both sides of the material guide mechanism 3 to move towards each other. This drives the inner sliding shaft rod 44 in the rotating mechanism 4 on both sides of the material guide mechanism 3 to slide towards each other in the rotating cylinder 43, thus automatically bending the cold-rolled steel plate between them. At the same time, the positioning frame 47 rotates on one side of the U-shaped rotating frame 46, and the torsion spring 482 is compressed.

[0054] At the location of the unloading zone A4, the ball bearing 452 in the rotating mechanism 4 contacts the second U-shaped rod 64. When the rotating mechanism 4 is transported to the unloading zone A4, the second U-shaped rod 64 abuts against the ball bearing 452, keeping the automatically bent cold-rolled steel sheet in a bent state, making the bending process of the cold-rolled steel sheet more thorough.

[0055] A method for manufacturing a cable tray includes the following steps:

[0056] Step 1: Adjust the distance between the two guiding mechanisms 3 according to the different widths of cold-rolled steel sheets, control the start of the second motor 27, and use the belt pulley transmission group 26 to drive the double-headed screws 25 on both sides to rotate synchronously, drive the two mounting bases 23 to move towards each other or away from each other, drive the two guiding mechanisms 3 to move towards each other or away from each other, thereby flexibly adjusting the distance between the two guiding mechanisms 3 to adapt to the processing of cold-rolled steel sheets of different widths;

[0057] Step 2: Control the start of the first motor 36 to drive the transmission gear 37 to rotate the crown gear 35, thereby driving the corresponding guide shaft 32 and guide wheel 33 to rotate, which in turn drives the guide belt 34 to perform transmission, thereby driving multiple rotating and stationary mechanisms 4 to drive synchronously, and automatically transporting the material from the feeding area A1 to the processing area A2, bending area A3 and unloading area A4 in sequence.

[0058] Step 3: When the rotating mechanism 4 moves to the feeding area A1, the first U-shaped rod 63 abuts against the ball 452, placing the cold-rolled steel plate between the positioning plate 471 and the positioning frame 47. The electric telescopic rod 472 is activated to drive the positioning plate 471 to move, clamping and positioning the cold-rolled steel plate.

[0059] Step 4: The cold-rolled steel sheet is moved to processing area A2. The positioning crossbar 61 abuts against the ball bearing 452, and the rotating gear 49 and the transmission rack 491 mesh. As the rotating mechanism 4 and the cold-rolled steel sheet continue to be transported, the transmission rack 491 drives the transmission rack 491 to rotate, which in turn drives the rotating cylinder 43 to rotate, drives the inner sliding shaft rod 44 to rotate synchronously, and drives the U-shaped rotating frame 46 to rotate the cold-rolled steel sheet that is clamped and positioned, so that the cold-rolled steel sheet transported to processing area A2 can be rotated and dried by the spraying mechanism and the drying mechanism.

[0060] Step 5: After processing, the cold-rolled steel sheet is moved to the bending area A3. The reducing angle bar 62 abuts against the ball bearing 452. The annular slide 492 limits the rotation of the rotating gear 49 to prevent the rotating gear 49 from rotating on its own. As the rotating mechanism 4 continues to transmit power, the reducing angle bar 62 drives the ball bearing 452 and the limiting cylinder 45 in the rotating mechanism 4 on both sides of the material guide mechanism 3 to move towards each other. This drives the inner sliding shaft 44 in the rotating mechanism 4 on both sides of the material guide mechanism 3 to slide towards each other in the rotating cylinder 43, automatically bending the cold-rolled steel sheet between them. At the same time, the positioning frame 47 rotates on one side of the U-shaped rotating frame 46, and the torsion spring 482 is compressed.

[0061] Step Six: After the cold-rolled steel sheet is automatically bent, it moves to the unloading area A4. The second U-shaped rod 64 abuts against the ball bearing 452, keeping the automatically bent cold-rolled steel sheet in a bent state, making the bending process more thorough until the cold-rolled steel sheet is bent into shape. Then, the electric telescopic rod 472 is activated again to drive the positioning plate 471 to move in the opposite direction. The cold-rolled steel sheet loses its clamping and positioning and disengages from the rotating mechanism 4 for automatic unloading.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

6. A method for manufacturing a cable tray using the manufacturing apparatus of claim 5, characterized in that, The process includes the following steps: Step 1: Adjust the distance between the two guiding mechanisms according to the different widths of cold-rolled steel sheets. Control the second motor to start, and use the belt pulley drive group to synchronously drive the double-headed screws on both sides to rotate, causing the two mounting bases to move towards or away from each other, and thus causing the two guiding mechanisms to move towards or away from each other, thereby flexibly adjusting the distance between the two guiding mechanisms to adapt to the processing of cold-rolled steel sheets of different widths; Step 2: Control the first motor to start, drive the transmission gear to rotate the crown gear, thereby driving the corresponding guide shaft and guide wheel to rotate, and then driving the guide belt to perform transmission, thereby... Multiple rotating and fixing mechanisms are synchronously driven, automatically transporting the cold-rolled steel plate from the feeding area (A1) to the processing area (A2), bending area (A3), and unloading area (A4) in sequence. Step three: When the rotating and fixing mechanism moves to the feeding area (A1), the first U-shaped rod abuts against the ball bearing, placing the cold-rolled steel plate between the positioning plate and the positioning frame. The electric telescopic rod is activated to drive the positioning plate to move, clamping and positioning the cold-rolled steel plate. Step four: The cold-rolled steel plate moves to the processing area (A2), the positioning crossbar abuts against the ball bearing, and the rotating gear and transmission rack mesh. As the rotating and fixing mechanism and the cold-rolled steel plate continue to transport, the transmission rack drives the transmission... The rack rotates, which in turn drives the rotating cylinder to rotate, causing the inner sliding shaft to rotate synchronously. This, in turn, drives the U-shaped rotating frame and the clamped and positioned cold-rolled steel sheet to rotate, facilitating the rotary spraying and drying of the cold-rolled steel sheet transported to the processing area (A2) via the spraying and drying mechanisms. In step five, after processing, the cold-rolled steel sheet is moved to the bending area (A3). The reduced-pitch inclined rod abuts against the ball bearings, and the annular slide limits the rotation of the rotating gear to prevent it from rotating on its own. As the rotating mechanism continues to transmit power, the reduced-pitch inclined rod drives the ball bearings and the limiting cylinder in the rotating mechanism on both sides of the material guide mechanism to move towards each other. Meanwhile, the inner sliding shaft rods in the rotating mechanism of the two guide mechanisms slide in opposite directions within the rotating cylinder, automatically bending the cold-rolled steel plates. At the same time, the positioning frame rotates on one side of the U-shaped rotating frame, and the torsion spring is compressed. In step six, after the cold-rolled steel plates are automatically bent, they move to the unloading area (A4). The second U-shaped rod abuts against the ball bearings, keeping the automatically bent cold-rolled steel plates in a bent state, making the bending process more thorough until the cold-rolled steel plates are bent into shape. Then, the electric telescopic rod is activated again to drive the positioning plate to move in the opposite direction, and the cold-rolled steel plates lose their clamping and positioning and are automatically unloaded from the rotating mechanism.
