Problems solved by technology

Due to the high brittleness of tungsten metal, the tungsten rod is not straight enough. When the electrode seat and the electrode clamp block clamp the tungsten rod, the clamping force is too large, which leads to the direct fracture of the tungsten rod.
The patent with the notification number CN203887383 U is a tungsten rod welding device based on screw connection technology. It is heated first, preheated, and then connected and welded by electrode clamps. However, this process needs to be moved by mechanical clamps. There are clamping and lifting during the process, which may cause the relatively brittle tungsten rod to break, and there is a risk

Embodiment 1

[0017] Such as Figure 1-2 As shown, a tungsten rod welding device based on screw connection technology includes a guide rail 1, the guide rail 1 is set as two left and right, and electrode holders and heaters are installed on the two guide rails 1, and the two electrode holders are located on two heating surfaces. The inner side of the device, the heater can be equipped with a torch head, which can be heated by gas combustion. These are all included in the reference materials, which are not the focus of this device, so they will not be described in detail. The guide rail 1 is fixed on the lower bottom plate through the support rod. , and the middle part of the inner cavity of the guide rail 1 is provided with a downwardly penetrating slot, and two upper and lower pressure plates 2 are arranged in the slot, and the outer ends of the two pressure plates 2 are provided with a vertically outward lower threaded rod 3, and the lower threaded rod The outer end of 3 is connected with...

Abstract

The invention discloses a tungsten rod welding device based on the screw connecting technology. The tungsten rod welding device comprises guide rails. The two guide rails are arranged left and right.A T-shaped sliding block is arranged at the front end of the middle of a connecting pipe. Sliding grooves in cooperation connection with the sliding block are formed in the rear ends of the guide rails. Tungsten rods are arranged in the guide rails and penetrate corresponding heaters and electrode seats. The contact ends of the two tungsten rods are connected through an electrode clamp. The tungsten rods are placed between two press plates from the front side, due to the fact that two upper threaded rods are connected through the same spring, the extrusion force of the press plates to the tungsten rods is constant, and too large pressure cannot be generated; if the two press plates slide on the tungsten rods, even though the tungsten rods are bent, the diameter of each tungsten rod is basically unchanged, and therefore even though sliding happens, the force between the two press plates cannot be changed; the manner is different from common spring extrusion, the force is guaranteed, meanwhile, the tungsten rods can be moved by pushing a handle, ascending and descending cannot be generated, and greater safety is achieved; and the extrusion force can be adjusted through a rotating handle.

Description

technical field [0001] The invention relates to a welding device, in particular to a tungsten rod welding device based on screw rod connection technology, which belongs to the field of tungsten rod welding. Background technique [0002] Tungsten is a metal with a high melting point, and general gas welding cannot perform welding between tungsten rods. When the resistance welding machine welds the tungsten rods, first clamp the tungsten rods through the electrode holder and the electrode clamp block, and then connect the two tungsten rods. When the tungsten rods are connected, a voltage is applied between the electrode holders, so that a large current is generated on the docking surface Generate high heat to melt the tungsten on the butt surface of the two tungsten rods, and quickly apply forging force to the two tungsten rods to weld the two tungsten rods into one tungsten rod. Due to the high brittleness of tungsten metal, the tungsten rod is not straight enough. When the ...
