Pressure gauge laser welding machine main features

This customized pressure gauge laser welding machine which we specially designed for famous Germany WIKA company, it adopts imported golden plating laser cavity, 6KW dual pulse Xe-lamp.Wave current can control the switch power supply,high power.Pulse programmable and intellectualized system management, industrial PC control(three or four axis).Configuration precision X and Y axis, the two mobile platforms and high into the elevator, you can manually and do focus .customer can choose the optional rotary working table(φ80mm or φ125mm).

CCD Monitor system and 3P water cooling system.

1,  Application background.

Automatic pressure gauge laser welding machine is mainly applied to the instrument industry case automatic welding.
At present we have hard light path and optical fiber transmission type two kinds of laser welding machine for this application.

2,  System introduction

This scheme is the table for the instrument industry or in need of special welding trajectory and the development of special fixture, with automatic control system.

3, We developed the specal laser welding fixtures for different diameter pressure gauges, exact picture as follows:

4, Full automatic laser welding for 8 sides of pressure gauge total time less than 90 seconds, high precision, beautiful welding, no need for secondary polishing, high efficiency, the real pressure gauge laser welded pictures as follows:

5, This laser welding machine is easy to operate, the rought working flow as follows:

5.1, the equipment is energized, the power indicator light.

5.2, open the software, set the relevant parameters and trajectory;

5.3, manual products will be clamped;

5.4, "Running" button, workbench automatically according to the trajectory, the top sleeve press, welding gasket and the case of four sides, four sides after welding, automatic recovery of the top sleeve, four edges welded gasket and header;

5.5, the welding is completed, table back to the feeding point;

5.6, manually removed after welding products;

5.7, the next product according to the process 3 to 6 cycle.

6, Interface

Data input: Computer interface: WINDOWS.
