Embodiment Construction

[0012] figure 1 , 2 The shown clamp for butt welding includes a cylinder 1 , a pressing arm 2 , a sheet positioning block 3 , two pressing plates 4 , a bracket 5 , and a slide rail 6 . The top of the support 5 is a platen 7, and the bottom of the support 5 is slidably arranged on the slide rail by rollers 11. The pressing arm is hinged on the bracket through the shaft 8 near the middle part; the two pressing plates 4 are hinged at the front end of the pressing arm through the shaft 9; the rear end of the pressing arm is hinged with the piston rod of the cylinder 1. The cylinder block of cylinder 1 is connected on the bracket 5 . A copper plate 10 is inlaid on the platen opposite to the pressing plate; a copper strip is arranged at the bottom of the pressing plate.

[0013] Pushing and pulling up and down the cylinder 1, the pressing arm 2 swings around the axis 8, and the pressing plate 4 installed on the pressing arm 2 also moves up and down, thereby pressing the workpiece...

Abstract

The invention provides a clamp for butt welding, which can flatten a material plate so as to perform the butt welding on material plates conveniently. The clamp comprises a bracket and two pressure plates, wherein the bracket is provided with a bedplate; and the pressure plates are parallel with the bedplate, provided with gaps and connected with a transmission mechanism which can drive the pressure plates to move towards the bedplate. When the clamp is in use, the two pressure plates are driven to move towards the bedplate by the transmission mechanism, so that two material plates can be compressed between the pressure plate and the bedplate and prevented from warping and convenience is brought to welding.

Description

technical field [0001] The invention relates to a fixture for butt welding. Background technique [0002] In the production of stainless steel welded pipe, since the stainless steel material plate is a roll of a coil, the length is certain, while the welded pipe is produced continuously, the material plate needs to be welded between the material plates, and the two material plates that need to be welded If there is warping, you need to use a jig to flatten them before welding. After welding, the weld seam needs to be ground. [0003] There is a kind of fixture in the German welded pipe production line, cutting, welding and grinding are placed on the same equipment. The way of double-cylinder pressing plate is adopted, and the material plate is cut and then welded and polished. The fixture does not have a cooling device; due to space constraints during welding, it is inconvenient to use and the equipment cost is relatively high. Contents of the invention [0004] The pu...
