Problems solved by technology

There are more than ten steel grating manufacturers in China, but the pressure welding machines are basically imported equipment. A certain company in Yantai is a manufacturer of self-developed and designed pressure welding machines, but the pressure welding machine is AC power supply, single twist steel welding, And only flat steel grating below 50mm can be welded, and the welding appearance quality is poor
There are many countries in the world that can produce pressure welding machines, such as Japan, South Korea, Australia, and the United States, but the specific models are different, but most of them have some shortcomings, mainly in low efficiency, high failure rate, and cannot produce more than 60mm large size steel grating

Embodiment Construction

[0013] The present invention is made up of pressure welding machine 2, intermediate feeding roller table 16 and head cutting machine. As shown in Figures 1 and 2, a flat steel stepping trolley 5 and a flat steel fixture 6 sit under the front end of the pressure welding machine base 7, and a twist steel feeding trolley 3 and a twist steel lifting mechanism 4 are fixed on the top, and the flat steel stepper There is a code disc automatic positioning device on the trolley 5, which can ensure the stepping accuracy of the flat steel. Fix the pallet 8 on the pressure welding machine base 7 at the rear end of the flat steel fixture 6, fix the receiving platform 11 on the pallet 8, and hinge through the four connecting rods 9 on the pressure welding machine base 7 close to the rear end of the receiving platform 11 , The flush baffle plate 10 controlled by the hydraulic cylinder. Above the receiving platform 11 is the positive and negative electrode row 12, the positive and negative e...

Abstract

The present invention relates to a steel checkered plate pressure welding machine. It is formed from pressure welding machine, intermediate feeding roller way and head-cutting machine. Said pressure welding machine can utilize heavy current to make twist steel and flat steel be instantaneously stitched, then the progressively stitched steel checkered plate can be passed through the intermediate feeding roller way and fed into the head-cutting machine, said head-cutting can be used for cutting off the excess twist steel.

Description

(1) Technical field [0001] The invention relates to a welding technology, in particular to a pressure welding machine which press-welds flat steel and cross bars arranged and positioned between the positive and negative electrodes in a certain way to form a steel grating by direct current welding. (two), background technology [0002] Steel grating is an indispensable economical engineering material in modern industry. There are more than ten steel grating manufacturers in China, but the pressure welding machines are basically imported equipment. An enterprise in Yantai is a manufacturer of self-developed and designed pressure welding machines, but the pressure welding machine is AC power supply, single twist steel welding, And only flat steel grating below 50mm can be welded, and the welding appearance quality is poor. There are many countries in the world that can produce pressure welding machines, such as Japan, South Korea, Australia, and the United States, but the spec...
