[0005] The disadvantage of the above scheme is that it only introduces which welding method is used to weld the root band, and the overall introduction is not comprehensive; Welded together, annealing and sandblasting the weld, and finally forming a circle of saw blades, called the root band; the shape of the root band is basically fixed after butt welding, so in the process of butt welding, how to ensure its shape stability and How to effectively position the root zone during welding and assist in improving the quality of root zone welding is extremely important

Embodiment Construction
[0050] Below in conjunction with accompanying drawing and embodiment of description, specific embodiment of the present invention is described in further detail:
[0051] refer to Figure 1 to Figure 13 The welding equipment for a bimetallic saw blade shown includes a gantry 1. The welding equipment includes a laser generator 1a, a forming fixture 2, an auxiliary forming device and two positioning devices arranged symmetrically. The forming fixture 2 is a cylindrical structure , and it is vertically fixedly installed on the front side of the gantry 1, the laser generator 1a, one of the positioning devices, the auxiliary forming device and the other positioning device are distributed along the circumferential interval of the forming jig 2 in the forming Around the fixture 2, the laser generator 1a is upside down and installed vertically above the molding fixture 2 through the cross servo driver 1b. The outer peripheral surface of the molding fixture 2 is provided with a welding...

Abstract
The invention relates to the field of duplex metal saw blade machining, in particular to a welding equipment and method of a duplex metal saw blade. The welding equipment of the duplex metal saw bladecomprises a portal frame, a laser generator, an auxiliary forming device, two positioning devices and a cylindrical molding jig. The forming jig is arranged on the front side of the portal frame, theauxiliary forming device is arranged below the forming jig, and the two positioning devices are symmetrically arranged on the periphery of the forming jig; the laser generator can vertically and movably arranged above the forming jig, a limiting plate is arranged on the back side of the forming jig, and a plurality of limiting blocks are arranged on the outer periphery surface of the forming jig;and a movable limiting device is arranged on the back surface of the portal frame, the limiting plate and the inner sides of all the limiting blocks form a limiting material channel, and a preformingdevice is arranged between the auxiliary forming device and the forming jig. The welding equipment of the duplex metal saw blade can enable a pre-welding root zone to be automatic formed and effective positioned, the stability in the welding process is accelerated, and thus, the welding quality is improved.
Description
technical field [0001] The invention relates to the field of bimetallic saw blade processing, in particular to a welding device and a welding method for a bimetallic saw blade. Background technique [0002] Bimetallic band saw blades mainly refer to metal cutting band saw blades in which the tip material is high-speed steel or other high-performance steel, and the saw band material is low-alloy spring steel. [0003] In the production process of bimetallic band saw blades, root band butt welding is an important process in the band saw blade production process. At present, the root band butt welding of bimetallic band saw blades is mostly carried out on imported CNC butt welding machines. The single price is 100 More than ten thousand yuan, the welding effect is good, but the price is expensive, and it is not suitable for batch use on the production line. It is not expensive to buy a domestic bimetallic butt welding machine, but the company has many product specifications, a...
