Abstract

The utility model relates to special equipment of using laser for surface quenching to a corrugated roller. The utility model comprises a lathe bed, a main shaft driving construction, a clamping tool, a numerical control servo-system, and a top rest. The top rest is fixedly provided with a laser head platform; a light guiding focusing device are fixed on the platform; the utility model also comprises a laser generator fixed on the lathe bed and a light guiding movable joint; the light guiding focusing device comprises a reflecting lens and a convex lens. The equipment has convenient operation and quick processing speed. The surface of the processed corrugated roller has high hardness. The utility model is suitable for processing light energy beaten down on part of large complicated work pieces, groove, hole, etc.

Description

With laser the corrugation roller is carried out hard-faced specific equipment

The utility model relates to a kind of quenching apparatus, particularly a kind ofly with laser the corrugation roller is carried out hard-faced specific equipment.

Metal parts is done in the surperficial process of thermal treatment, quenching is a very important procedure, improve hardness of metal materials by quenching, but deal with more time-consuming with quenching apparatus in the past, material hardness is also not really desirable, some large complicated part is handled restricted, therefore, is necessary to provide a kind of specific equipment of quenching.

The purpose of this utility model provides a kind ofly makes the specific equipment of surperficial quench treatment to the corrugation roller, and this operation of equipment is easy, and speed is fast, and is effective.

For achieving the above object, the utility model is by the following technical solutions: the corrugation roller is made hard-faced specific equipment comprise lathe bed, worktable, spindle drive and jig, digital control servo system, upper slide rest, be fixed with the laser head platform on the described upper slide rest, fix a leaded light, focuser on the platform, also comprise the laser generator that is fixed on the lathe bed, with the leaded light active section that leaded light focuser, laser generator join, described leaded light focuser comprises speculum, convex lens.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1: the utility model structural representation

Fig. 2: leaded light, focuser structural representation among Fig. 1

The vertical view of Fig. 3: Fig. 2

Among Fig. 1,6 for being positioned at the worktable on the lathe bed, and corrugation roller 5 is supported on the jig 7, the corrugation roller is driven by spindle drive and rotates, and 3 for being positioned at the laser head platform on the upper slide rest, fixes a leaded light, focuser 2 on the platform, 1 is laser generator, and it is fixed on the lathe bed, generally adopts Nd ³⁺YAG Solid State Laser producer, on sale on the market, about 1 kilowatt-5 kilowatts of its power also can adopt CO ₂Laser generator, 4 is laser source.

8 is speculum in leaded light, the focuser among Fig. 2, the laser that produces from laser generator passes through leaded light active section 10, and (also available photoconductive fiber) arrives speculum, and laser beam directive convex lens 9 after reflection focuses on, laser after the focusing is laser source 4, and it is used for the corrugation roller is made quench treatment.Change the convex lens position and regulate the laser facula size, the hot spot scope is between 0.1-6mm.The laser head platform is driven by spindle drive and makes vertically (X-axis) and laterally (Y-axis) motion, and processing mode has: laser head is done the straight line back and forth movement, Workpiece Rotating certain angle behind the stroke; Laser head is done the straight line back and forth movement, and workpiece rotates; Motion and workpiece that laser head is done X-axis, Y-axis rotate.

The course of processing is to control with digital control servo system (SCK-350), be that servomotor dragged upper slide rest and drives laser head and moves along X-axis after computer sent X-axis walking instruction, the pulse encoder feedback system and instruction that is positioned at the servomotor rear side compares, after reaching requirement, the X-axis stop motion.In like manner, the rotation of workpiece is also by computer control.Machined material can be carbon steel, steel alloy, also can be used for pottery processing, for example depiction etc.Laser beam is the hot spot local heating to workpiece surface in the laser processing heat treatment process, temperature is very high at the position, processing district, and it is little to position, non-processing district temperature effect, can make the metallic surface realize the consolidation process rapidly like this, thereby obtain more thinner needle type martensites in the metallic surface, so just improved metal skin hardness and wear resistance greatly.

The utility model advantage: it is very fast to adopt laser that part is made surperficial Quenching Treatment firing rate, produces effect The rate height can be realized self-quench hardening, does not need the hardening medias such as oil or water, and cost is low, easily realizes numerical control etc., can Regulate as required the spot size of leaded light focalizer, and select watt level, this equipment applied range, For at the bottom of the cell wall, the privileged sites such as aperture, blind hole, deep hole and chamber tube inwall, as long as light beam can shine The place all can process, can carry out the sclerosis of heavy parts local surfaces and the sclerosis of complex-shaped part Process.
