DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0030] With reference to Figure 1 and Figure 2 An embodiment provided by the present application is welding equipment for cold-rolled ribbed steel bar mesh for concrete buildings, which comprises a shell 1, a material receiving frame 2 fixedly connected to one side of the shell 1 and used for receiving and storing processed steel bars, a welding electrode 3 arranged inside the shell 1, the welding electrode 3 being made of high-performance aluminum copper oxide, which is a dispersion strengthening type powder metallurgy, the biggest feature of which is excellent pitting corrosion self-healing property, excellent thermal fatigue resistance caused by thermal shock, higher electrical conductivity, higher strength, less bonding and plastic deformation during operation, and a service life 5 to 10 times that of traditional chromium zirconium copper, a feeding belt 4 fixedly connected to one side of the shell 1, the feeding belt 4 being used to convey the steel bars from the feeding end to the welding area and ensure the continuity and stability of the steel bars during processing, and a straightening device arranged on the surface of the feeding belt 4 and used for preliminarily straightening the steel bars.

[0031] The straightening device comprises a support plate 5 fixedly connected to the upper surface of the feeding belt 4, a motor 6 fixedly connected to one side of the support plate 5, the motor 6 being a power source for driving the operation of the whole straightening device, a transmission wheel 7 fixedly connected to the output end of the motor 6, a transmission belt 8 rotatably connected to the outer wall of the transmission wheel 7, a rotating wheel 9 rotatably connected to the inside of the transmission belt 8, and an extrusion wheel 10 fixedly connected to one side of each of the transmission wheel 7 and the rotating wheel 9, the extrusion wheel 10 having a certain groove structure and being used for clamping and correcting the steel bars, the steel bars being kept in a straight line state by the friction force and the correction force when the steel bars pass through the straightening device, so that the steel bars are prevented from deviating or irregularly bending during conveying.

[0032] Specifically, in the production process of cold-rolled ribbed steel bars, although a series of rolling processes are carried out, due to factors such as equipment precision and process parameter fluctuation, part of the steel bars will have a certain degree of bending deformation when leaving the factory. When the steel bars are transported on the feeding belt 4, the motor 6 drives the transmission wheel 7 to rotate through its output end, so that the transmission wheel 7 drives the transmission belt 8 to move. The transmission belt 8 forces the rotating wheel 9 to rotate synchronously through its cooperation with the rotating wheel 9, and in turn drives the synchronous rotation of the extrusion wheel 10. The surface of the extrusion wheel 10 is provided with grooves, which can effectively prevent the steel bars from deviating or sliding during the transmission process, and ensure the stable movement of the steel bars. The synchronous movement between the two extrusion wheels 10 produces a bidirectional clamping action on the steel bars, forming a combined action of friction and correction force, and uniformly pressing the bent steel bars. Through this physical action, the steel bars are gradually corrected to a straight line form, avoiding the influence of the subsequent processing or machining due to the bending of the steel bars during the conveying process.

[0033] With reference to Figure 3 The limiting assembly includes a fixed rod 11 and a support frame 12. The fixed rod 11 is fixedly connected to the upper surface of the feeding belt 4 and serves as a stable support. The fixed rod 11 ensures that it can stably bear the weight of the entire limiting assembly and provides the required support force to ensure that the feeding belt 4 does not deviate or shake during operation. The support frame 12 is fixedly connected to the inside of the fixed rod 11 at the bottom. A transmission block 14 is slidingly connected inside the support frame 12. A spring 13 is arranged inside the support frame 12 and serves as a buffer and a limiting device. The spring 13 is fixedly connected to the upper surface of the fixed rod 11 at one end and to the bottom of the transmission block 14 at the other end.

[0034] Specifically, during welding, the electrode will exert pressure on the intersection of the steel bars. At the same time, the impact force generated by the electric current and the vibration of the welding equipment itself will cause the steel bars to have the risk of displacement. When the steel bars enter the inside of the fixed wheel one 17, the entry of the steel bars will generate a certain extrusion force, which will cause the transmission block 14 and the fixed wheel two 18 to move simultaneously. While the transmission block 14 moves downward, it forces the spring 13 to elastically deform. The deformation of the spring 13 stores part of the energy, allowing the system to have a certain buffering effect, preventing excessive impact force from damaging the structure. Through the movement of the transmission block 14, the two fixed blocks 16 on the sides are further offset. The two fixed blocks 16 interact with each other to form a stable clamping force on both sides of the steel bars, ensuring that the steel bars do not deviate or vibrate during processing.

[0035] With reference to Figure 3The support frame 12 is internally rotatably connected with a fixed block 16, the fixed block 16 is rotatably connected with the inner wall of the support frame 12 through a pair of bearing devices, so that the fixed block 16 can freely rotate in the support frame 12, the fixed block 16 is internally rotatably connected with a roller 15, the rolling of the roller 15 can effectively drive the fixed block 16 to move along the track of the transmission block 14, the roller 15 rolls on the outer wall of the transmission block 14, the fixed block 16 is internally rotatably connected with a fixed wheel one 17, the surface of the fixed wheel one 17 has smaller friction with the outer wall of the reinforcing bar, which can reduce the resistance generated in the transmission process, the transmission block 14 is internally rotatably connected with a fixed wheel two 18, the outer wall of the transmission block 14 is slidably connected with a limiting block 19, which is used to limit the movement of the transmission block 14 and prevent it from moving off, and the limiting block 19 is fixedly connected with the inner side of the support frame 12 on one side.

[0036] Specifically, at the same time, the special shape design of the transmission block 14 enables it to drive the roller 15 to roll on the outer wall, the roller 15 plays a more precise transmission role under the driving of the transmission block 14, further transmits the force to the fixed block 16 to make it move synchronously, thereby ensuring that the reinforcing bar is accurately centered during entering the fixed wheel one 17, avoiding the problem of inaccurate reinforcing bar form caused by deviation, through the action of the fixed block 16, the reinforcing bar changes its form in the direction of the correction force applied by the straightening component, thereby ensuring the stability and straightness of the reinforcing bar, the fixed block 16 and the transmission block 14 work together to ensure that the reinforcing bar is firmly fixed during centering, limiting the lateral and longitudinal displacement of the reinforcing bar, in this way, during the welding process, the reinforcing bar can always be kept in the correct position, so that the welding parts such as electrodes of the welding equipment can accurately act on the welding point of the reinforcing bar, avoiding the position deviation of the welding point caused by the displacement of the reinforcing bar, thereby improving the welding quality and welding efficiency.

[0037] Working principle: in use, the device is used to weld the steel bar, the steel bar is conveyed to the welding area by the feeding belt 4, and the steel bar is welded by the welding electrode 3 when it reaches the welding area, the welding electrode 3 is a high-performance aluminum oxide copper, as the welding electrode 3, when the feeding belt 4 conveys the steel bar, the transmission wheel 7 is driven to rotate by the motor 6 output, the transmission belt 8 is further driven to move under the rotation of the transmission wheel 7, the rotation wheel 9 is forced to move synchronously by the movement of the transmission belt 8, the extrusion wheel 10 is synchronously rotated under the driving of the transmission belt 8 and the rotation wheel 9, the surface of the extrusion wheel 10 is provided with a groove to prevent the steel bar from deviating in it, the steel bar is straightened by the extrusion of the two extrusion wheels 10, the steel bar will enter the fixed wheel one 17 after being straightened, the transmission block 14 and the fixed wheel two 18 will move simultaneously when the steel bar enters, the spring 13 will be elastically deformed when the transmission block 14 moves downward, the two side fixed blocks 16 will be offset by the movement of the transmission block 14, the roller 15 will roll on the outer wall of the transmission block 14 by the special shape of the transmission block 14, so that the force is further transmitted to the fixed block 16 to make it move synchronously, the function of automatically centering and fixing the steel bar to be welded is realized, the transverse and longitudinal displacement of the steel bar is firmly limited, so that it can only change its shape according to the correction force applied by the straightening part, and the electrode and other welding parts of the welding equipment can accurately act on the corresponding position for welding, avoiding the position deviation of the welding point caused by the displacement of the steel bar.

[0038] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
