Steel grating plate press welder

Abstract

The invention discloses a steel grating plate press welder which comprises an oil tank (1), an upper cross beam (2), upright posts (3), a main oil cylinder (4), transformers (5), diode rectifying assemblies (6), slide blocks (7), an upper clamping plate (11), upper clamping cylinders (12), guide posts (13), a lower clamping plate (14), a lower cross beam (15), limiting plates (16), a bottom electrode (17), lower clamping plate cylinders (18), a servo motor (23), a ball screw (24) and a bottom electrode seat (26). The steel grating plate press welder is characterized in that: the upper end of the ball screw (24) is connected with a feeding frame (19); the lower sides at the two ends of the feeding frame (19) are connected with straight guide rail bottom plates (21) through straight guide rails (20); the lower ends of the straight guide rail bottom plates (21) are connected with the lower cross beam (15); the middle part at the upper end of the feeding frame (19) is connected with the lower clamping plate cylinder (18), and the two ends of the feeding frame (19) are connected with the guide posts (13); and the upper ends of the guide posts (13) are connected with the lower clamping plate (14). Therefore, the press welder is simple in structure, high in welding speed, high in feeding accuracy, convenient to use and particularly suitable for pressing steel grating plates.

Description

Technical field: [0001] The invention relates to a welding device, in particular to a steel grid plate pressure welding machine. Background technique: [0002] The steel grating is composed of load flat steel and cross bars perpendicular to the load flat steel, each arranged at a certain interval, and each intersection point of the load flat steel and the cross bar is welded and fixed by a pressure welding machine. At present, the production The countries of the steel grid plate pressure welding machine mainly include the United States, Japan, Australia and South Korea. The imported equipment has been imitated in China since 2000. The feeding mechanism of the steel grid plate pressure welding machine is a stepping trolley, and the feeding guide mechanism adopts a dovetail guide rail , The feeding and clamping mechanism adopts hydraulic clamping, which has defects such as large volume, complex structure, poor precision, and slow feed speed.
