Die laser welding machine with operating rod control laser head

Abstract

The invention relates to a laser welding machine for maintain a die by horizontally moving a laser head. The laser welding machine comprises a mainframe box arranged on a main machine frame, an operating panel and a laser arm with a vertical-motion support. A laser generator and a laser reflection cavity are installed in an optical bench, and a working mainframe is arranged in the mainframe box. The laser welding machine for maintain the die by horizontally moving the laser head further comprises a laser head moving operating panel and an optical bench horizontal-motion device installed on the vertical-motion support of the laser arm. The optical bench with the laser generator and the laser reflection cavity is fixed on the optical bench horizontal-motion device, and the optical bench horizontal-motion device is connected with the laser head moving operating panel, can be an X-Y axis plane moving device and can also be other devices such as a rotating shaft sliding block moving device. By conveniently controlling and moving the laser head, die restoring efficiency can be improved and working strength of a working stable is reduced.

Description

technical field [0001] The invention relates to the technical field of mold welding equipment, in particular to a laser welding machine which increases the horizontal movement function of a laser head to facilitate the repair of molds other than workbenches.

[0002] Mold has the title of "mother of industry". The production of almost all products is inseparable from the mold. During the process of making and using the mold, it is inevitable that there will be modification and wear. In order to save costs, it is usually remedied to save it. Expensive production and modification costs. The traditional mold repair methods include argon arc welding, cladding welding and sheet cold welding, etc., but these methods have their own defects: the temperature of argon arc welding is too high, which is easy to cause mold deformation; Overlay welding and repair welding are loose and easy to fall off; although the temperature of sheet cold welding is low, it cannot repair the cavity surface and the finish is not enough. These methods cannot meet the repair of precision molds

[0003] The laser repair that has just emerged recently can effectively avoid the above-mentioned defects. The laser repair mold process originated in Germany. After the related equipment was introduced from China, the industry developed rapidly. A small number of domestic laser manufacturers have also carried out imitation production, and the products are mainly for The "hard optical path laser welding machine" for small and medium-sized precision mold repairs, the common mold welding machines in the market, all have mobile workbenches, which belong to the mold mobile repair technology. Usually, the limit load-bearing capacity of the workbench of the laser welding machine is relatively light, and at most it can only bear 100kg, the load-bearing capacity of the workbench is quite limited. When the weight of the mold is close to or exceeds the load-bearing capacity of the workbench, it will often cause the workbench to be overstressed and deformed. There are many problems: 1. The life of the workbench is greatly reduced; 2. The positioning accuracy and smoothness become worse during welding; 3. Due to the movement of the X and Y axes, the handle needs to be rotated separately to operate, and there are many handwheels for manual rotation in both directions. The time is inconvenient, and the complicated operation leads to low processing efficiency; 4. Because the worktable moves independently on the two axes of X and Y, it is impossible to go obliquely. Limited, it is necessary to manually move the mold to adjust the position, which is time-consuming and laborious, resulting in a complicated laser repair process and difficult repair work
