Description

Technical Field

[0001] The invention relates to the technical field of quenching equipment, and in particular to a machine tool guide rail quenching equipment and method. Background Art

[0002] Machine tool guides need to be quenched during processing. Machine tool guides are large and small. Large machine tool guides are mostly quenched with intelligent quenching equipment, and small machine tool guides are generally quenched manually. Most of the quenching is done by heating first and then quenching with coolant. The existing quenching methods are mostly divided into two types: one is to directly flush the heated machine tool guide with coolant, and the other is to quench in pool water.

[0003] When quenching small machine tool guide rails: 1. If the quenching is carried out by flushing with coolant, the coolant-related devices are generally installed on the quenching equipment, and basically the quenching is carried out by flushing while heating. In actual use, part of the flushing coolant will splash onto the heating coil, causing the heating coil part to cool down due to moisture, which will further cause uneven heat in the heating coil, and further cause uneven heating of the machine tool guide rails, which may not only cause cracks or even breakage of the machine tool guide rails during the quenching process, but also cause uneven hardness of the machine tool guide rails. This hardness difference may affect the performance and service life of the machine tool guide rails, causing deformation and outer wall quality problems of the machine tool guide rails during use; 2. If the machine tool guide rails are directly placed in a water pool for quenching, the operator is usually required to accurately control the placement speed. If the operation volume is large, it will not only cause mental and physical fatigue of the operator, but also the high surrounding temperature of the heating will cause the operator to be baked by the heat.

[0004] In addition, the heating coils and heating pipelines in the existing machine tool guide rail quenching devices are basically exposed to the outside. Operators may be easily burned by the heat generated by the heating pipelines and heating coils, splashing coolant during the flushing process, or accidental touch during the quenching operation.

[0005] More importantly, when heating the machine tool guide rails, a clamp with a small machine tool guide rail is usually held and placed in a heating coil for heating. However, during the operation, if the operator makes an operating error and causes the machine tool guide rail to contact the heating coil, it will cause damage to both the machine tool guide rail and the heating coil. There is also a certain danger for the operator. Therefore, the applicant proposed a machine tool guide rail quenching equipment and method to solve the above-mentioned problems.

10. A quenching method for a machine tool guide rail quenching device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. First, the machine body starts to work, which will then heat up the heating pipeline and the heating coil. This is a prior art and will not be described in detail here. After reaching the temperature, one end of the machine tool guide rail is placed on the platform plate and moved forward, so that it enters the first fixed cylinder (521). During the movement, the first grinding strip (522) is deformed during the extrusion, and the first grinding strip (522) also performs a first grinding on the outer wall of the machine tool guide rail. When the machine tool guide rail passes through the second fixed cylinder (531) and moves, the second grinding strip (532) is deformed during the extrusion, and the second grinding strip (532) also performs a second grinding on the outer wall of the machine tool guide rail. S2, the machine tool guide rail that has been polished twice will enter the sliding cavity, thereby causing the second elastic sheet (514) and the first elastic sheet (513) to deform, and the bottom support platform plate (512) will support the bottom of the machine tool guide rail, and further contact the wiping pad, and the wiping pad will wipe off the polishing dust, and the dust will fall onto the bottom support platform plate (512) and slide through the bottom support platform plate (512) into the C-shaped heat insulation cover (33) for storage; S3. Subsequently, the machine tool guide rail enters the heating coil for heating. The machine tool guide rail is further moved so that it contacts the top of the support plate (414). At the same time, the external water supply device is turned on, and the coolant enters the water injection pipe through the hose. The water injection pipe then enters the U-shaped pipe (423), further enters the annular pipe (421), and is then ejected from the ejection pipe (422). When the machine tool guide rail enters the water storage ring groove (412), the machine tool guide rail is fully quenched and cooled. The used coolant remains in the water storage ring groove (412) and is discharged from the drain pipe (413).
