Two-position sectional material welding machine

Abstract

The invention relates to a two-position sectional material welding machine. The sectional material two-position welding machine comprises a machine body, machine heads, an operation cabinet and an electric control cabinet, wherein a translation guide rail is arranged at the upper end of the machine body and the machine heads are slidingly mounted on the translation guide rail; at least two machine heads are arranged; a front upper pressing clamp, a welding plate and a rear upper pressing clamp are sequentially arranged on a working platform of each machine head; the front upper pressing clamps are fixedly arranged on the upper surfaces of the corresponding working platforms from front to back and the rear upper pressing clamps are slidingly arranged on the upper surfaces of the corresponding working platforms; a rear positioning back plate is fixedly arranged on the upper surface of each rear upper pressing clamp and a vertical positioning back plate is fixedly arranged on the upper surface of each front upper pressing clamp; the rear positioning back plates and the corresponding vertical positioning back plates are vertical mutually; the outer end surfaces of the rear positioning back plates are leveled with the outer side surfaces of the vertical positioning back plates; the upper parts of the machine heads are connected with double-piston-rod air cylinders for driving the welding plates to lift up and fall by flange plates; and adjusting screw rods are further connected with the tops of the double-piston-rod air cylinders and screw sleeves are arranged outside the adjusting screw rods. The two-position sectional material welding machine has the advantages that the operation is simple and convenient, the structure is compact and is not complicated, the fault rate is relatively low, the safety performance is reliable, and the like.

Description

technical field [0001] The invention relates to a welding machine, in particular to a profile two-position welding machine. Background technique [0002] With the country's increasing energy-saving requirements, how to more effectively enhance the energy-saving performance of doors and windows has become a problem that many door and window companies need to solve. As an important component of the strength and sealing of doors and windows, corner joints play an important role in energy-saving indicators. At present, domestic general plastic steel doors and windows use ordinary welding equipment to weld their corners, that is, the common structure of 45° top welding type is used, which leads to relatively not fine and high-end production of doors and windows, poor style, weak aesthetics and low efficiency. . [0003] At the same time, when the profile is made of plastic steel and other materials, the welding requirements for the corners of the profile are higher. In order to...

Problems solved by technology

At present, domestic general plastic steel doors and windows use ordinary welding equipment to weld their corners, that is, the common structure of 45° top welding type is used, which leads to relatively not fine and high-end production of doors and windows, poor style, weak aesthetics and low efficiency.

[0003] At the same time, when the profile is made of plastic steel and other materials, the welding requirements for the corners of the profile are higher. In order to protect the appearance of the composite material, it is necessary to precisely control the welding time and welding feed. At present, door and window manufacturers When welding the corners of profiles, there is less protection for the splicing surface, and the delivery accuracy of the welding equipment is low, which cannot meet the production of new doors and windows
