DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0023] A pre-bending and shaping device for steel cage steel bars, see Figure 1-Figure 6 As shown, it includes a support frame 1, a limit block 2, a first connecting rod 3, a wheel 4, a hinge door 5, a first motor 6, a disc 7, a support rod 8, a first nut 801, a support plate 9, a sliding plate 10, a sliding rod 11, a second nut 1101, a connecting plate 12 and a rotating shaft 13. Four limit blocks 2 are evenly spaced on the rear side of the support frame 1 by welding, the front and rear sides of the support frame 1 are both welded with a first connecting rod 3, the left and right ends of the first connecting rod 3 are rotatably provided with wheels 4, the front side of the support frame 1 is rotatably provided with a hinge door 5, a storage slot 501 is opened on the front side of the support frame 1, the rear side of the support frame 1 is embedded with a first motor 6, the output shaft of the first motor 6 is welded with a disc 7, and the inside of the disc 7 is evenly spaced with sliding A support rod 8 is dynamically provided, and a first nut 801 is threadedly provided at the rear end of the support rod 8. A support plate 9 is provided on the support frame 1 by bolt connection, and a sliding plate 10 is provided on the rear side of the support plate 9 by welding. Three sliding rods 11 are slidably provided inside the sliding plate 10, and a second nut 1101 is threadedly provided at the front end of the sliding rod 11. A connecting plate 12 is sleeved on the outermost sliding rod 11, and a rotating shaft 13 is rotatably provided on the upper end of the connecting plate 12. It also includes a connecting block 14, a support column 15 and a screw 16. The connecting blocks 14 are slidably provided on both the front and rear sides of the support frame 1, and support columns 15 for fixing the support frame 1 are welded on both the left and right sides of the connecting block 14, and screws 16 are threadedly provided on both the front and rear sides of the support frame 1.

[0024] When the device is needed, the staff moves the support frame 1. When the support frame 1 moves, the wheels 4 rotate to reduce the friction between the support frame 1 and the ground, making it easier for the staff to move the support frame 1. When the support frame 1 moves to a suitable location, the staff stops moving the support frame 1, and then the staff rotates the screw 16 downward, thereby causing the connecting block 14 to drive the support column 15 to move downward and contact the ground, so that the wheels 4 are in a suspended state and disengage from the ground, and the support frame 1 is fixed on the ground, thereby preventing the wheels 4 from rotating to cause the support frame 1 to move, thereby improving the stability of the support frame 1 and facilitating the staff to operate the device to pre-bend and shape the steel bars. When the steel bars need to be pre-bent and shaped, the staff rotates the first nut 801 outward to loosen the support rod 8, and the staff moves the support rod 8 to a suitable position, and the staff rotates the first nut 801 inward to fix the support rod 8 on the disc 7, and then the staff rotates the second nut 1101 outward, and the staff takes the sliding rod 11 out of the sliding plate 10 and disengages it from the connecting plate 12. The staff puts the connecting plate 12 on the appropriate sliding rod 11. After putting it on, the staff puts the sliding rod 11 back into the sliding plate 10, so that the position of the connecting plate 12 corresponds to the position of the support rod 8. The staff turns the second nut 1101 inward to fix the sliding rod 11 on the sliding plate 10, thereby achieving the effect of adjusting the position of the support rod 8 and the connecting plate 12 according to the diameter of the steel bar that needs to be pre-bent and shaped, thereby improving the applicability of the device. Then the staff inserts one end of the steel bar into between any two support rods 8 to contact the rotating shaft 13, the staff turns on the first motor 6, and the output shaft of the first motor 6 rotates to drive the disc 7 to rotate, thereby making the steel bar be pre-bent and shaped around the support rod 8. During the pre-bending and shaping process, the rotating shaft 13 plays a guiding role, so that the steel bar can be better wrapped around the support rod 8. When the steel bar is pre-bent and shaped, the staff turns off the first motor 6, and the staff uses a welding gun to weld the connection of the steel bar. After welding is completed, the staff uses a cutting tool to cut the steel bar. The staff repeats the above steps to pre-bend and shape the steel bar. Example

[0025] Based on Example 1, see Figure 1 and Figure 4 As shown, it also includes a mounting frame 17, a translation cylinder 18 and an automatic electric welding gun 19. The mounting frame 17 is arranged on the front side of the support frame 1 by welding, and the translation cylinder 18 is arranged on the upper end of the mounting frame 17 by welding. The automatic electric welding gun 19 for welding steel bars is arranged on the telescopic rod of the translation cylinder 18 by key connection.

[0026] After the pre-bend of the steel bar is finalized, the staff turns on the translation cylinder 18, controls the extension of the telescopic rod of the translation cylinder 18, and then drives the automatic welding gun 19 to move downward and contact the connection of the steel bar. The staff controls the telescopic rod of the translation cylinder 18 to stop extending, and then turns on the automatic welding gun 19 to weld the connection of the steel bar, thereby facilitating the welding operation of the steel bar. After the welding is completed, the staff turns off the automatic welding gun 19, controls the shortening of the telescopic rod of the translation cylinder 18, and then drives the automatic welding gun 19 to move upward, and the staff turns off the translation cylinder 18.

[0027] See also Figure 1 and Figure 5 As shown, it also includes a fixed block 21, a second connecting rod 22, a guide plate 23, a support block 24, a second motor 25, a baffle 29, a second rotating rod 27, a blade 28 and a belt 26. The front side of the support frame 1 is symmetrically provided with a fixed block 21 by welding, and the second connecting rod 22 is welded inside the fixed block 21. A guide plate 23 is slidably arranged between the two second connecting rods 22, and a support block 24 is welded on the guide plate 23. The second motor 25 is bolted on the support block 24, and a baffle 29 is welded on the rear side of the second motor 25. The second rotating rod 27 is rotatably arranged inside the baffle 29. A blade 28 for cutting steel bars is welded on the left end of the second rotating rod 27, and a belt 26 is connected between the output shaft of the second motor 25 and the second rotating rod 27.

[0028] When the steel bar welding is completed, the staff moves the guide plate 23 backward to make the blade 28 contact the welding part of the steel bar, and then the staff turns on the second motor 25. The output shaft of the second motor 25 rotates to drive the rotating rod 27 to rotate through the belt 26, and then drives the blade 28 to rotate to cut the welding part of the steel bar, thereby facilitating the steel bar cutting operation. During the cutting process, the baffle 29 acts as a material blocking role to prevent iron filings from splashing and injuring the staff. After the steel bar cutting is completed, the staff turns off the second motor 25 and moves the guide plate 23 forward to reset it.

[0029] See also Figure 5 As shown, a first protective shell 30 is also included. The first protective shell 30 for protection is provided on the right side of the second motor 25 by welding, and the belt 26 is located inside the first protective shell 30 .

[0030] The first protective shell 30 plays a protective role and prevents the belt 26 from being exposed to the outside and being damaged.

[0031] See also Figure 1 and Figure 4 As shown, a rubber sleeve 31 is also included, and the wheel 4 is covered with a rubber sleeve 31 for anti-skid.

[0032] When the wheel 4 rotates, the rubber sleeve 31 plays an anti-skid role, increases the friction between the wheel 4 and the ground, prevents the wheel 4 from rotating too fast, and enables the staff to move the support frame 1 smoothly.

[0033] See also Figure 1 and Figure 3 As shown, a second protective shell 32 is also included. The rear side of the support frame 1 is provided with a second protective shell 32 for protection by welding, and the first motor 6 is located inside the second protective shell 32 .

[0034] The second protective shell 32 plays a protective role, preventing the first motor 6 from being exposed to the outside and being damaged.
