introduction

This technology is based on the principle of thin-plate automatic welding machine and is designed and developed for the characteristics of thin plates. In the technology development, the cylinder-driven double-link double-slide synchronous scissors device was independently designed and designed to reduce the space size and reduce the investment cost of hydraulic shearing. At the same time, the new conductive structure of the resistance seam welding head was innovatively designed to simplify The conductive structure reduces energy consumption, and the innovative design reduces the amount of copper used, saving users the cost of purchasing.

First, the market situation

The thin plate automatic narrow lap welding machine is mainly used in the continuous production line of deep processing of metallurgical enterprises. It is to join the rolled steel strips by welding, or to connect the narrower steel sheets into wider steel sheets. The cold rolled sheet must be subjected to deep processing to obtain galvanized sheet, tin plate, chrome plate, color steel plate, silicon steel plate, automobile plate, and the like. In order to meet the continuous production requirements, various processing units use a coiled steel strip for continuous production. The product can also be used for wide-panel splicing of automotive skinning production lines;

At present, the thin and plate automatic narrow lap welding machine at home and abroad is divided into high and low grade welding machines: the domestic welding price of the automatic welding machine (high-grade welding machine) is about 2 million yuan, the price of imported welding machine is about 12 million yuan; the semi-automatic welding machine ( Low-grade welding machine) is mainly used by small and medium-sized enterprises in China and Asia, and the domestic price is about 500,000 yuan.

Second, technical background analysis

Domestic thin-plate automatic narrow lap welding machine has a high market share, including Chengdu Welding Research Technology and Wuhan. Most domestic enterprises mainly use the imitation imported equipment structure in the manufacture of such welding machines. Based on the deep technical development of state-level high-tech enterprises, Chengdu Welding Research Technology has independently developed a new type of thin-plate automatic narrow-lap automatic welding with independent intellectual property rights to adapt to domestic production lines on the basis of learning, understanding, active research and digestion. machine.

Third, equipment analysis

The existing automatic welding machines are currently costly, affecting the use of some customers, and a large number of private enterprises use simple welding machines with lower cost. Although the weld quality is poor, the price advantage makes it have the largest market share. As the manufacturer's requirements for product quality continue to increase, the speed of the production line is required to be higher and higher, and the requirements for the welding machine are also increased. The customer hopes that there is a welding machine between the high end and the low end, which has a higher cost performance. The fully automatic welding machine, the new thin plate automatic narrow lap welding machine developed by the welding research technology is the thin plate production line that satisfies such customer groups.
