[0002] Cable trays are usually installed in computer rooms and hoisted on the roof of the room. They are used to lay optical fibers or electrical wires. There are also cable trays installed outdoors, which are also mainly used for wiring.

[0003] At present, the frame part of the wiring rack is mostly a U-shaped steel structure, and the U-shaped steel is mostly formed by punching a straight sheet into a U-shaped structure with the help of a stamping equipment.

After the sheet is stamped, manual labor or a material-picking mechanism is also required to remove the stamped sheet from the stamping table. However, it is difficult for manual labor or a material-picking mechanism to coordinate the loading and taking of the sheet with the action of the stamping equipment, resulting in relatively low stamping efficiency.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0031] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0032] See also Figure 1 as well as Figure 2 The present embodiment provides a fully automatic forming device for a cable rack, comprising a bottom plate 10, a limit block 20, a bending assembly 30, an elastic support assembly 40, a driving assembly 50, a magnetic assembly 60 and a hydraulic cylinder 70. The upper edge of the bottom plate 10 is fixedly provided with a top plate 102 by a plurality of vertical rods 101. The upper center position of the bottom plate 10 is fixedly provided on a support seat 103. The limit blocks 20 are provided in two groups. The two groups of limit blocks 20 are arranged above the support seat 103 and are relatively distributed. The bottoms of the two groups of limit blocks 20 are fixed by a group of elastic supports. The component 40 is connected to the base plate 10, and the magnetic component 60 is provided with four groups. The four groups of magnetic components 60 are arranged between the two groups of limit blocks 20. The hydraulic cylinder 70 is installed at the bottom of the top plate 102. The bending component 30 is arranged above the two groups of limit blocks 20 and is controlled by the hydraulic cylinder 70 to move up and down. The driving component 50 is arranged on the side of the two groups of limit blocks 20. When the elastic support component 40 pushes the two groups of limit blocks 20 to move upward, the driving component 50 is used to drive the four groups of magnetic components 60 to rotate 90°.

[0033] When it is necessary to perform continuous stamping on the U-shaped frame of the wiring rack, several frame sheets can be placed on the upper part of the support seat 103 so that the several sheets are stacked vertically. Then, the hydraulic cylinder 70 drives the bending assembly 30 to move downward. When the bending assembly 30 moves downward, it acts on the two groups of limit blocks 20 so that the two groups of limit blocks 20 and the four groups of magnetic assemblies 60 move downward as a whole. At this time, the two groups of elastic support assemblies 40 are compressed. When the group of magnetic assemblies 60 located below moves downward, it acts on the uppermost sheet material on the upper part of the support seat 103, thereby adsorbing the uppermost sheet material. Then, the hydraulic cylinder 70 drives the bending assembly 30 to move upward, and the elastic support assembly 40 drives the two groups of limit blocks 20 and the four groups of magnetic assemblies 6 0 moves up, and the magnetic attraction component 60 at the bottom attracts the uppermost sheet material to move up synchronously when it moves up. After the uppermost sheet material moves up a certain distance, the driving component 50 drives the four groups of magnetic attraction components 60 to rotate 90 degrees as a whole, and the lowermost magnetic attraction component 60 transfers the uppermost sheet material it has attracted to the side position of the limit block 20. Then the hydraulic cylinder 70 drives the bending component 30 to move down again, and the bending component 30 acts on the two groups of limit blocks 20 and then drives the two groups of limit blocks 20 and the four groups of magnetic attraction components 60 to move down again. At this time, the magnetic attraction component 60 rotated to the bottom acts on the second upper sheet material and adsorbs the second upper sheet material. Then the hydraulic cylinder 70 drives the bending component 30 to move up again, and the elastic support component 40 pushes the two groups of limit blocks 2 0 and the four groups of magnetic components 60 move up again, the magnetic component 60 located at the bottom attracts the second upper sheet material to move up, and when the second upper sheet material moves up a certain distance, the driving component 50 drives the four groups of magnetic components 60 to rotate 90 degrees again, and the uppermost sheet material that was previously transferred to the side is transferred to the position above the two groups of limit blocks 20, and the second upper sheet material is transferred to the side of the two groups of limit blocks 20, and then the hydraulic cylinder 70 drives the bending component 30 to move down again. At this time, the bending component 30 moves down to act on the uppermost sheet material, and the uppermost sheet material is pressurized and drives the two groups of limit blocks 20 to move down again. When the two groups of limit blocks 20 move down a certain distance, the uppermost sheet material forms a U-shaped structure on the outside of the two groups of limit blocks 20, and is located at The lower group of magnetic components 60 again absorbs the group of sheet materials above the support seat 103, and then the hydraulic cylinder 70 drives the bending component 30 to move upward again, the elastic support component 40 pushes the two groups of limit blocks 20 to move upward again, and the driving component 50 drives the four groups of magnetic components 60 to rotate 90° again, and the second upper layer of sheet materials is transferred to the top of the two groups of limit blocks 20, and the sheet materials punched into a U-shaped structure are transferred from the top of the two groups of limit blocks 20 to the other side along with the corresponding magnetic components 60; the above-mentioned hydraulic cylinder 70 drives the bending component 30 to move up and down, and cooperates with the setting of the elastic support component 40, the driving component 50 and the four groups of magnetic components 60, to achieve continuous automatic stamping of several frame sheets.

[0034] See also Figure 1In one embodiment, the bending assembly 30 includes a bending rod 301 and a support plate 302. The support plate 302 is installed at the output end of the hydraulic cylinder 70. The bending rod 301 is provided with two groups. The two groups of bending rods 301 are installed at the bottom of the support plate 302 and are distributed relative to each other. The two groups of bending rods 301 are respectively arranged on the opposite sides of the two groups of limit blocks 20.

[0035] When a group of sheet materials is transferred to the top of the two groups of limit blocks 20, the hydraulic cylinder 70 drives the support plate 302 to move downward, and then drives the two groups of bending rods 301 to move downward. When the two groups of bending rods 301 move downward, they act on the upper part of the sheet materials and apply pressure to the sheet materials. When the sheet materials are under pressure, their two ends bend and fit onto the side walls of the two groups of limit blocks 20, thereby forming a U-shaped structure.

[0036] See also Figure 1 In one embodiment, the elastic support assembly 40 includes a first guide sleeve 401, a first elastic member 402 and a first support rod 404. The first guide sleeve 401 is fixedly arranged on the upper part of the base plate 10. The upper end of the first support rod 404 is fixedly connected to the bottom of the limit block 20, and the lower end extends to the inside of the first guide sleeve 401 and is telescopically matched with the first guide sleeve 401. The first support rod 404 is located on the rod body outside the first guide sleeve 401 and is fixedly provided with a ring block 403. One end of the first elastic member 402 is connected to the first guide sleeve 401, and the other end is connected to the ring block 403, which is used to provide elastic support for the ring block 403.

[0037] When the hydraulic cylinder 70 drives the support plate 302 and the two sets of bending rods 301 to move downward, the two sets of bending rods 301 act on the upper part of the sheet, thereby driving the sheet and the two sets of limit blocks 20 to move downward synchronously. At this time, the first support rod 404 moves toward the inside of the first guide sleeve 401, and the first elastic member 402 is compressed. When the lower end of the first support rod 404 acts on the inner bottom of the first guide sleeve 401, the two sets of limit blocks 20 no longer move downward, and the two sets of bending rods 301 drive the sheet to bend between the two sets of limit blocks 2 0 side wall, thereby forming a U-shaped structure; after the current sheet is stamped and bent, the hydraulic cylinder 70 drives the support plate 302 and the two sets of bending rods 301 to move upward, the first elastic member 402 pushes the ring block 403 and then drives the first support rod 404 to move upward, and the first support rod 404 drives the limit block 20 to move upward. When the limit block 20 moves up to the original height, as the two sets of bending rods 301 continue to move upward, the two sets of bending rods 301 are removed from the opposite sides of the two sets of limit blocks 20 and separated from the sheet of the U-shaped structure.

[0038] See also Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4504 , the gear 502 is fixed to the bottom plate 10 at the bottom end, and the upper end is connected to the gear 502 at the bottom end.

[0039] When the hydraulic cylinder 70 drives the support plate 302 and the two sets of bending rods 301 to move downward, the two sets of bending rods 301 act on the sheet material above the two sets of limit blocks 20 to enter and drive the two sets of limit blocks 20 to move downward. When the two sets of limit blocks 20 move downward, the rotating shaft 501 and the gear 502 move downward synchronously. At this time, the gear 502 pushes the several bevel gear pieces 504 and then drives the several bevel gear pieces 504 to deflect in the direction of the fixed rod 503 in sequence. The gear 502 and the several bevel gear pieces 504 cannot mesh. After the gear 502 separates from the lowest set of bevel gear pieces 504, as the limit block 20 continues to move downward, the lower end of the first support rod 404 acts on the inner bottom of the first guide sleeve 401, and the two sets of bending rods 301 drive the sheet material to bend and stick to the side walls of the two sets of limit blocks 20, thereby forming a U-shaped structure. At the same time, the magnetic suction component 60 located below acts on the upper part of the support seat 103 The first set of limit blocks 20 is driven by the first elastic member 402, which pushes the first support rod 404 and then drives the two sets of limit blocks 20 to move upward. The two sets of limit blocks 20 drive the rotating shaft 501, the gear 502 and the four sets of magnetic components 60 to move upward. When the magnetic component 60 at the bottom attracts the sheet and drives the sheet to move upward, after the sheet moves up a certain distance, the gear 502 acts on the lowest set of beveled teeth 504. The beveled teeth 504 push the gear 502 and then drive the gear 502 to rotate. The subsequent beveled teeth 504 push the gear 502 in turn, causing the gear 502 and the rotating shaft 501 to rotate 90°, thereby driving the four sets of magnetic components 60 to rotate 90°. The magnetic component 60 at the bottom is connected to transfer the adsorbed sheet to one side of the two sets of limit blocks 20.

[0040] See also Figure 1 、 Figure 2 as well as Figure 4In one embodiment, the magnetic attraction component 60 includes a second support rod 601, a magnet 602, a third elastic member 603 and a second guide sleeve 604. The second guide sleeve 604 is fixedly arranged on the shaft of the rotating shaft 501 between the two groups of limit blocks 20. One end of the second support rod 601 extends to the outside of the two groups of limit blocks 20 and is fixedly connected to the magnet 602, and the other end extends to the inside of the second guide sleeve 604 and is connected to the inner wall of the second guide sleeve 604 through the third elastic member 603. The third elastic member 603 is used to provide elastic support for the second support rod 601.

[0041] When the hydraulic cylinder 70 drives the support plate 302 and the two sets of bending rods 301 to move downward, the two sets of bending rods 301 act on the sheet material above the two sets of limit blocks 20, thereby driving the two sets of limit blocks 20, the rotating shaft 501 and the gear 502 to move downward. When the rotating shaft 501 moves downward, a group of magnets 602 located below the two sets of limit blocks 20 move downward and act on a group of sheet material on the upper part of the support seat 103, thereby adsorbing the sheet material. After the sheet material is adsorbed, as the two sets of bending rods 301 continue to move downward, the lower end of the first support rod 404 acts on the inner bottom of the first guide sleeve 401, and the two sets of limit blocks 20 stop moving downward. The two sets of bending rods 301 apply pressure to the sheet material above the two sets of limit blocks 20, so that the magnet 602 located above the two sets of limit blocks 20 moves downward. When the magnet 602 moves downward, it drives the corresponding second support rod 601 to move toward the inside of the corresponding second guide sleeve 604, so that the corresponding third elastic When the two sets of bending rods 301 are pressed and bent, the hydraulic cylinder 70 drives the support plate 302 and the two sets of bending rods 301 to move upward, and the first elastic member 402 pushes the two sets of limit blocks 20, the rotating shaft 501 and the gear 502 to move upward. When the two sets of bending rods 301 are removed from the sides of the two sets of limit blocks 20, the upper group of magnets 602 is pushed by the corresponding third elastic member 603 and then moves toward the upper part of the two sets of limit blocks 20 to push the U-shaped sheet away from the outside of the two sets of limit blocks 20. Subsequently, several oblique teeth 504 engage with the gear 502 to push the rotating shaft 501 and the four groups of magnets 602 to rotate 90°. The upper group of magnets 602 drives the U-shaped sheet to rotate 90°.

[0042] See also Figure 4In one embodiment, the four groups of magnets 602 are all electromagnets, and a C-shaped conductive sheet 201 is fixedly provided on the side wall of one group of limit blocks 20 facing the other group of limit blocks 20. The C-shaped conductive sheet 201 is electrically connected to an external power supply (not shown in the figure). A group of conductive rods 605 is fixedly provided on the side wall of each group of second guide sleeves 604. The end of the conductive rod 605 away from the corresponding second guide sleeve 604 can contact the C-shaped conductive sheet 201. Each group of conductive rods 605 is connected to the corresponding magnet 602 through a group of conductive rods 606.

[0043] When the rotating shaft 501 drives the four sets of guide sleeves 604 to rotate from bottom to top, the conductive rods 605 on the side walls of the four sets of guide sleeves 604 are in contact with the C-shaped conductive sheet 201. During this process, the external power supply can be used to supply power to the magnet 602 through the C-shaped conductive sheet 201, the conductive rod 605 and the wire 606, so that the magnet 602 generates magnetism to adsorb the sheet material so that the sheet material can be transferred smoothly. When the sheet material above the two sets of limit blocks 20 is stamped and bent into a U-shaped structure, as the rotating shaft 501 drives the four sets of guide sleeves 604 to rotate from bottom to top, the conductive rods 605 on the side walls of the four sets of guide sleeves 604 are in contact with the C-shaped conductive sheet 201. The second guide sleeve 604 rotates further, and the U-shaped sheet material is rotated to the side of the two sets of limit blocks 20 by the corresponding magnet 602 and the corresponding guide sleeve 604. At this time, the conductive rod 605 on the side wall of the second guide sleeve 604 rotates to the opening of the C-shaped conductive sheet 201 and then separates from the C-shaped conductive sheet 201. The magnet 602 is powered off and demagnetized, and no longer adsorbs the U-shaped sheet material. The U-shaped sheet material falls off from the outside of the magnet 602 by itself, thereby realizing automatic unloading of the U-shaped sheet material after stamping and bending.

[0044] In one embodiment, the first elastic member 402 , the second elastic member 505 and the third elastic member 603 may be springs or metal springs, which are not limited here.

At this time, the two groups of elastic support assemblies 40 are compressed, and when the group of magnetic assemblies 60 located below moves downward, it acts on the uppermost sheet material on the upper part of the support seat 103, and then adsorbs the uppermost sheet material, and then the hydraulic cylinder 70 drives the bending assembly 30 to move upward, and the elastic support assembly 40 drives the two groups of limit blocks 20 and the four groups of magnetic assemblies 60 to move upward, and the lower When the upper magnetic component 60 moves up, it attracts the uppermost sheet material and moves up synchronously. When the uppermost sheet material moves up a certain distance, the driving component 50 drives the four groups of magnetic components 60 to rotate 90 degrees as a whole. The lowermost magnetic component 60 transfers the uppermost sheet material it has attracted to the side position of the limit block 20. Then the hydraulic cylinder 70 drives the bending component 30 to move down again. The bending component 30 acts on the two groups of limit blocks 20 and then drives the two groups of limit blocks 20 and the four groups of magnetic components 60 to move down again. At this time, the magnetic component 60 rotated to the bottom acts on the second upper sheet material and adsorbs the second upper sheet material. Then the hydraulic cylinder 70 drives the bending component 30 to move up again, and the elastic support component 40 pushes the two groups of limit blocks 20 and the four groups of magnetic components 60 to move up again, and is located at the bottom The magnetic component 60 on the right attracts the second upper sheet material to move upward. After the second upper sheet material moves up a certain distance, the driving component 50 drives the four groups of magnetic components 60 to rotate 90 degrees again. The uppermost sheet material that was previously transferred to the side is transferred to the position above the two groups of limit blocks 20, and the second upper sheet material is transferred to the side of the two groups of limit blocks 20. Then the hydraulic cylinder 70 drives the bending component 30 to move downward again. At this time, the bending component 30 moves downward to act on the uppermost sheet material. The uppermost sheet material is pressurized and drives the two groups of limit blocks 20 to move downward again. When the two groups of limit blocks 20 move down a certain distance, the uppermost sheet material forms a U-shaped structure on the outside of the two groups of limit blocks 20. At the same time, a group of magnetic components 60 located below again adsorbs a group of sheets above the support seat 103 , then the hydraulic cylinder 70 drives the bending assembly 30 to move up again, the elastic support assembly 40 pushes the two groups of limit blocks 20 to move up again, and the driving assembly 50 drives the four groups of magnetic assemblies 60 to rotate 90° again, and the second upper sheet material is transferred to the top of the two groups of limit blocks 20, and the sheet material punched into a U-shaped structure is transferred from the top of the two groups of limit blocks 20 to the other side along with the corresponding magnetic assembly 60; the above-mentioned hydraulic cylinder 70 drives the bending assembly 30 to move up and down, and cooperates with the arrangement of the elastic support assembly 40, the driving assembly 50 and the four groups of magnetic assemblies 60, to realize continuous automatic stamping of several frame sheets.
