Embodiment Construction
[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0035] See figure 1 , The present invention provides a steel bar welding device, including an operating platform 1 , a propeller 2 , a first clamp 3 , a hollow shaft 4 , a second clamp 5 and a driving device 6 . The pusher 2 is fixed on the operating platform, and the first steel bar 7 to be welded is inserted through the hole of the pusher 2 , and the pusher 2 is used to push the first steel bar 7 during the welding process. In order to fine-tune the position of the first steel bar 7 conveniently, an adjuster 8 is arranged at the front end of the pusher 2 . The first clamp 3 is fixed on the operating platform 1 downstream of the pusher 2 through a first support. In this embodiment, the first supporting member includes a hollow first steel casing 9 arranged in parallel on the operating platform 1 . The first steel casing 9 is fixed on the o...

The invention provides a steel bar welding device and a welding method. The steel bar welding device comprises a thruster, a first fixture, a hollow rotating shaft, a second fixture and a driving device, wherein the thruster is arranged on an operating platform; the first fixture is arranged on the operating platform by virtue of a first support piece; a bearing sleeves the hollow rotating shaft,the bearing is arranged on the operating platform by virtue of a second support piece, and the first support piece and the second support piece are oppositely arranged; the second fixture is connectedwith the hollow rotating shaft and is used for clamping and connecting a second steel bar which passes through the hollow rotating shaft with the hollow rotating shaft, the thruster, the first support piece and the second support piece are arranged in sequence, and the axis of the hollow rotating shaft coincides with that of the first support piece and the second support piece; and the driving device is connected with the hollow rotating shaft by virtue of a transmission mechanism. The welding method comprises a method for welding the steel bar by using the welding device. The steel bar welding device and the welding method have the advantages of low welding cost and high welding speed, the influence of the experience of operating personnel and human factors on the welding quality is less, obvious outer convex welding seams do not exist on the welded steel bar, and the diameter and the shape of the whole steel bar are consistent after welding.
Description
technical field [0001] The present invention relates to the technical field of welding, and more specifically, to a steel bar welding device and a welding method. Background technique [0002] Rebar as the main support structure has been widely used in modern bridges, tunnels, and construction projects. In actual use, the steel bars are mainly bound or welded to form a steel bar skeleton and placed in the joint hole or at the position of the precast concrete. According to the construction situation, it is sometimes necessary to weld the steel bars to increase the length of the steel bars or to weld multiple short steel bars to utilize the short steel bars, thereby saving steel and reducing costs. [0003] There are many welding methods for steel bars, generally there are six welding methods: flash butt welding, arc welding, electroslag pressure welding, submerged arc pressure welding, resistance spot welding and gas pressure welding. However, traditional welding methods re...
