[0022] As Figure 1 , Figure 4 shown, a welding and bending machine includes a base plate 1, a welding torch 31, a limiting member for fixing the steel bar 8, and a conveying frame for conveying the steel bar 8. A column 2 is fixedly connected to the base plate 1, a motor 12 is fixedly installed on the column 2, a turntable 3 is installed on the output end of the motor 12, an annular plate 4 is fixed on the edge of the turntable 3 for one week, an installation plate 10 is arranged on the column 2, a circular slideway 9 is arranged on the edge of the installation plate 10, and the slideway 9 and the annular plate 4 are arranged with the same rotation center; the slideway 9 is connected with a cross plate 5 rotating along the slideway 9, a cylinder 6 is installed on the cross plate 5, the welding torch 31 is installed on the output end of the cylinder 6, and the welding torch 31 is aligned with the annular plate 4; a locking member for locking the rotation of the cross plate 5 is arranged on the installation plate 10.

[0023] In the existing welding and bending machines, the steel bar 8 is clamped on the limiting member of the welding and bending machine, and the steel bar 8 is bent by rotating the turntable 3. After the rear end of the bent steel bar 8 contacts the front end of the next steel bar 8, the welding machine of the welding and bending machine is used to weld the end of the steel bar 8. The current problem is that the position of the welding machine is fixed, and the length of the assembled steel bar 8 is limited, and only steel bars 8 of a specific length can be assembled.

[0024] The improvement of the present invention lies in that: a circular slideway 9 is arranged on the installation plate 10, the slideway 9 is connected with a cross plate 5 rotating along the slideway 9, and the welding torch 31 is installed on the cross plate 5 through the cylinder 6. The cross plate 5 can rotate along the slideway 9, so as to adjust the position aligned by the welding torch 31, and is fixed by the locking member, so that steel bars 8 of different lengths can be welded on the welding and bending machine. Moreover, the welding torch 31 is installed on the cylinder 6, and the distance between the welding torch 31 and the steel bar 8 can be adjusted by telescoping the cylinder 6, thereby improving the welding accuracy.

[0025] Further, the locking member includes a plurality of first screw holes 11 provided on the mounting plate 10. The first screw holes 11 are arranged in an equidistant circular pattern around the rotation center of the slideway 9. A fastening bolt 13 is provided on the first screw hole 11 to lock the cross plate 5. When the cross plate 5 rotates to different positions along the slideway 9, the cross plate 5 can be fixed by inserting the fastening bolt 13 into the first screw hole 11 corresponding to the position of the cross plate 5.

[0026] As Figure 3 shown, further, the conveying frame includes a support housing 14. A vertical central groove 15 and side grooves 18 are provided on the support housing 14. A sleeve 16 for conveying steel bars is horizontally penetrated through the support housing 14. A moving block 29 is slidably connected to the side groove 18, and the moving block 29 is fixedly connected to the sleeve 16; a reinforcing bolt 30 is installed on the moving block 29; an electric saw 17 is installed on the support housing 14, and the electric saw 17 is located in the outlet direction of the sleeve 16. The conveying frame is a component for conveying the steel bar 8 into the welding and bending machine. The steel bars 8 transmitted from the rear have differences in height. According to the different heights of the steel bars 8, the height of the conveying part of the conveying frame needs to be adjusted. The sleeve 16 is used for sleeving the steel pipe to limit the steel bar 8, and the height of the sleeve 16 is adjusted according to the position of the moving block 29 on the side groove 18. After adjustment, the fixing is completed by using the reinforcing bolt 30, thereby completing the height adjustment of the steel bar 8.

[0027] Further, there are two side grooves 18 and moving blocks 29. The two side grooves 18 are respectively arranged on the left and right sides of the central groove 15, and the two moving blocks 29 are respectively fixedly installed on the left and right ends of the sleeve 16. Having two side grooves 18 and moving blocks 29 can increase the stability during the adjustment process.

[0028] Further, a support rod 20 is fixedly installed on the base plate 1. The upper end of the support rod 20 is slidably sleeved with a socket 19. The upper end of the socket 19 is fixedly installed at the bottom of the support housing 14. A plurality of equally spaced second screw holes 21 are provided on the support rod 20 in the vertical direction. A positioning bolt 22 is installed on the socket 19 for locking the second screw hole 21. The height adjustment range of the support rod 20 is relatively large. Compared with the fine adjustment of the moving block 29, the height adjustment of the support rod 20 is used for the overall height adjustment before use, and cooperates with the height adjustment of the sleeve 16 and the moving block 29 to complete the high-gradient and low-gradient adjustments.

[0029] As Figure 2As shown in the figure, further, the limiting member includes two limiting tubes 23 provided on the annular plate 4 for the steel bar 8 to pass through. The axial direction of the limiting tube 23 is the same as the tangent of the limiting tube at the annular plate 4. The distances of the two limiting tubes 23 from the center of the turntable 3 are equal and are spaced at a certain angle. On the side of the limiting tube 23 close to the inside of the turntable 3, a pushing block 24 is provided, and the pushing block 24 fits against the steel bar 8. The pushing block 24 is connected to a lead screw 25, and the turntable 3 is provided with threads, and the lead screw 25 passes through the turntable 3 and is threadedly connected. The moving directions of the lead screw 25 and the pushing block 24 are perpendicular to the axial direction of the limiting tube 23, and are used to press the steel bar 8 in the limiting tube 23. Conventional welding and bending machines all require a limiting member to limit the steel bar 8 to ensure the smooth progress of the bending of the steel bar 8. The limiting member of the present utility model is composed of a limiting tube 23 and a pushing block 24. The pushing block 24 is connected to a lead screw 25. By rotating the lead screw 25, the position of the pushing block 24 is adjusted, and then the steel bar 8 is pressed or released to complete the limitation of the steel bar 8.

[0030] Further, two adjusting grooves 26 are provided on the turntable 3, and the positions of the adjusting grooves 26 are correspondingly arranged at the positions of the limiting tubes 23. One end of the lead screw 25 away from the pushing block 24 is fixedly connected with a slider 27, and the slider 27 is slidably connected in the adjusting groove 26. After the adjusting groove 26 and the slider 27 are provided, the position of the lead screw 25 and the pushing block 24 can be adjusted by rotating the slider 27 at the adjusting groove 26, which is convenient for operation.

[0031] Further, scale lines 28 are provided on the adjusting groove 26, and the scale lines 28 are arranged along the moving direction of the lead screw 25. The limiting member includes two limiting tubes 23, and the steel bar 8 needs to be restricted at both positions. The best effect is achieved when the squeezing degrees of the pushing blocks 24 in the two limiting tubes 23 are the same. The scale lines 28 can be used to observe the squeezing degree of the pushing block 24, and then the steel bar 8 is locked to prevent it from shaking during bending or welding.
