A new process of laser cladding live column processing

Abstract

The invention discloses a new machining technology for a laser-cladding movable column. The new machining technology comprises the following steps that firstly, a central hole is repaired, specifically, the original deformed central hole is firmly welded through gas shielded welding, a plane is formed after simple surface polishing, and a new central hole is re-drilled on the plane; and secondly,laser cladding is conducted, specifically, dirt on the surface of the movable column is scrubbed through anhydrous ethanol, then the length of the movable column and the to-be-clad thickness are measured, focused red light of a laser is focused on the surface of the movable column, and then light opening for cladding is conducted. The new machining technology for the laser-cladding movable columnhas the economic benefits that material input of round steel with the diameter of 30 mm is reduced, the technological steps are reduced, the labor intensity of staff is lowered, the machining speed isfurther increased, the production progress is accelerated, and the economic benefits are increased; and the new machining technology for the laser-cladding movable column has the safety benefits thatno supporting seat is used in the new technology, hidden safety hazards are eradicated, and thus the safety benefits are increased.

Description

technical field [0001] The invention relates to the technical field of laser cladding, in particular to a new laser cladding live column processing technology. Background technique [0002] Laser cladding, also known as laser cladding or laser cladding, is a new surface modification technology. It adds cladding materials on the surface of the substrate and uses a high-energy-density laser beam to fuse it with the thin layer on the surface of the substrate to form a cladding layer that is metallurgically combined with it on the surface of the substrate; In the processing technology of the cladding column, the center point correction of the ordinary car is the first process, and it is also the most important process, which directly affects the processing quality of the laser coating and the CNC lathe and the quality of the finished product. Since the original center hole of the column head has already been deformed and deviated after the column was put into use underground, t...

Problems solved by technology

[0003] The original center hole correction process is guided by the factory. A round steel with a diameter of 30mm and a length of 30mm is welded on the column head as a support seat, and a new center hole is re-drilled at the center of the support seat. When installing the seat, firstly find the welding position of the support seat. If there is a slight deviation in the welding, the support seat and the live column are not concentric, and the center hole drilled will deviate from the center position of the support seat. The support seat is easy to be damaged during laser external application and CNC lathe processing. , and even cause the center hole to crack, and the workpiece will fall and be thrown out directly, causing the workpiece to be scrapped and the workpiece to hurt people.

Moreover, the process of welding the support seat is cumbersome, and it is necessary to process the round steel material with a diameter of 30mm and a length of 30mm in advance

After laser cladding the finished product, the support seat must be cut off with oxyacetylene to facilitate production and use, waste materials, many process steps, and potential safety hazards
