Abstract
Description
Technical Field
[0001] This utility model relates to a rebar guiding device in the field of rebar cage welding machine manufacturing technology. Background Technology
[0002] The main reinforcing bars of the steel cage are manually fixed by passing them through the corresponding holes in the template of the fixed rotating plate of the welding machine to the corresponding holes in the moving rotating plate. The ends of the coiled bars (wound bars) are pulled out from the winding plate and welded to a main reinforcing bar, ensuring the coiled bars are in close contact with the welding plate. Then, the coiled bars are wound around the main reinforcing bars by rotating the fixed and moving rotating plates (the moving plate moves backward while rotating). Simultaneously, the welding plate presses and welds the reinforcing bars onto the main reinforcing bars according to a set rhythm, thus forming the finished steel cage. However, when the main reinforcing bars are intermittently welded onto the welding plate, the reinforcing bars may sway left and right on the surface of the welding plate due to the winding and pulling of the rotating plates. Utility Model Content
[0003] The purpose of this invention is to provide a rebar guiding device that ensures that the rebar does not swing left and right during the welding process, so that the rebar can be accurately welded in the set position.
[0004] To achieve the above objectives, this utility model provides a rebar guiding device, including a frame, a welding plate on the upper part of the frame, a limiting structure at the lower end of the welding plate, a guiding mechanism in conjunction with the limiting structure, and the guiding mechanism being located at the lower part of the frame.
[0005] Compared with the prior art, the beneficial effect of this utility model is that after the end of the steel bar is pulled out and passes through the guiding mechanism and the limiting structure, it is vertically attached to the welding plate and the end is welded to the main bar. The rolling welding machine is started, and the fixed rotating disk and the moving rotating disk rotate to wrap the steel bar around the main bar. The welding plate intermittently presses the steel bar onto the main bar, which can ensure that the steel bar will not swing left and right during the welding process, so that the steel bar can be accurately welded in the set position.
[0006] As a further improvement of this utility model, the limiting structure includes a limiting block, a limiting groove is opened on the front of the limiting block, and the limiting block is fixedly connected to the bottom of the welding plate by bolts.
[0007] In this way, when the reinforcing bar is inserted into the limiting groove, its left and right sides are restricted by the limiting groove during the welding process, preventing it from moving left and right, thus ensuring that the reinforcing bar will not swing left and right.
[0008] As a further improvement of this utility model, the guiding mechanism includes a guide plate, the rear side of which is fixedly connected to the lower part of the frame, and multiple sets of pulley structures are installed on the front side of the guide plate, with the pulley structures cooperating with the limiting groove.
[0009] After the steel bar shaft is pulled out of the winding reel, it follows the multiple pulley structure and is inserted into the limiting groove of the limiting block from bottom to top along the front edge of the guide plate. This ensures that the steel bar can be continuously pulled out along a fixed line during the welding process and will not deviate.
[0010] As a further improvement of this utility model, the front edge of the guide plate is machined into an arc shape.
[0011] This allows the pulley structure to be arranged in an arc shape, so that the steel bars pulled out from the winding reel still maintain their original curvature, thus ensuring a smoother and less strenuous extraction process.
[0012] As a further improvement of this utility model, the pulley structure is provided with three sets, namely a lower pulley, a middle pulley and an upper pulley. The lower pulley is assembled and connected to the lower waist groove via the lower shaft. The lower waist groove is opened at the lower front part of the guide plate. The middle pulley is assembled and connected to the middle waist groove via the middle shaft. The middle waist groove is opened at the middle front part of the guide plate. The upper pulley is assembled and connected to the upper waist groove via the upper shaft. The upper waist groove is opened at the upper front part of the guide plate.
[0013] By adjusting the positions of the three pulleys on the corresponding three grooves, the bending range of the rebar can be adapted to be suitable for extraction, thereby further ensuring a smooth and unobstructed extraction process.
[0014] As a further improvement of this utility model, the limiting groove is provided on the limiting block with multiple grooves, each corresponding to a steel bar of different specifications.
[0015] By welding steel bars of different diameters in this way, it is possible to select and insert them into the corresponding sized limiting groove, thus avoiding the failure of the limiting groove to limit the steel bars due to its size being too large or too small. Attached Figure Description

Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings:
[0021] like Figure 1-3The rebar guiding device shown includes a frame 10, a welding plate 1 is provided on the upper part of the frame 10, a limiting structure is provided at the lower end of the welding plate 1, and a guiding mechanism is provided in conjunction with the limiting structure. The guiding mechanism is located at the lower part of the frame 10.
[0022] The limiting structure includes a limiting block 2, with a limiting groove 11 on its front side. The limiting block 2 is fixedly connected to the bottom of the welding plate 1 by bolts. Multiple limiting grooves 11 are formed on the limiting block 2, each corresponding to a steel bar of different specifications. The guiding mechanism includes a guide plate 7, the rear of which is fixedly connected to the lower part of the frame 10. Multiple sets of pulley structures are installed on the front of the guide plate 7, and these pulley structures cooperate with the limiting grooves 11.
[0023] The front of the guide plate 7 is machined into an arc shape. The pulley structure has three sets: a lower pulley 9, a middle pulley 6, and an upper pulley 4. The lower pulley 9 is connected to the lower waist groove 8 via the lower axle. The lower waist groove 8 is located at the lower front of the guide plate 7. The middle pulley 6 is connected to the middle waist groove 5 via the middle axle. The middle waist groove 5 is located at the middle front of the guide plate 7. The upper pulley 4 is connected to the upper waist groove 3 via the upper axle. The upper waist groove 3 is located at the upper front of the guide plate.
[0024] In this invention, the pulleys are arranged according to the arc-shaped front surface of the guide plate 7, and the positions of the three pulleys on the corresponding three waist grooves are adjusted to suit the bending amplitude when the steel bar is extracted, thereby ensuring a smooth and unobstructed extraction process.
[0025] The reinforcing bar passes through the limiting groove 11 of the limiting block 2 from bottom to top along the front edge of the guide plate 7, and then vertically upwards to fit against the welding plate 1. Because the reinforcing bar is inserted into the limiting groove 11, its left and right sides are restricted by the limiting groove 11 during welding, preventing it from moving left or right. This ensures that the reinforcing bar will not swing left or right, allowing it to be continuously extracted along a fixed path during welding without deviation. For welding reinforcing bars of different diameters, the corresponding limiting groove 11 can be inserted, avoiding the limitation effect of the limiting groove 11 being too large or too small. Furthermore, since there are many sizes of reinforcing bars, multiple limiting blocks 2 can be manufactured, each with a different sized limiting groove 11, allowing the selection of the appropriate limiting block 2 according to the different specifications of the reinforcing bars.
[0026] During welding, after the end of the reinforcing bar is pulled out from the winding reel, it goes down the lower pulley 9, the middle pulley 6 and the upper pulley 4, and then passes through the corresponding size of the limiting groove 11 on the limiting hole from bottom to top. After that, it is vertically attached to the welding plate 1 and the end is welded to the main reinforcing bar. The rolling welding machine is started, and the fixed rotating disk and the moving rotating disk rotate to wrap the reinforcing bar around the main reinforcing bar. The welding plate 1 intermittently presses the reinforcing bar onto the main reinforcing bar.
[0027] This invention ensures that the reinforcing bars do not sway left and right during the welding process, allowing them to be precisely welded to the designated positions.

Based on the technical solutions disclosed herein, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
