Description

Gas cutting device for cutting a testing sample}

The present invention relates to a gas cutting device in the cutting step after the rolling work of the plate, in particular to a specimen cutting device for improving the efficiency of the specimen cutting operation by easily cutting and transporting the specimen for the material test of the heavy plate will be.

In general, the heavy plate with a thickness of 45mm or more is used for various purposes, such as shipbuilding drying, industrial equipment manufacturing, various structures, etc., and strict quality control is required for each production process.

The heavy plate produced in the rolling process cuts the cropped portion, which is the front end, in the width direction after the cooling process, cuts the side surface of the heavy plate in the longitudinal direction, and then cuts it to the length required by the consumer.

Here, the cutting process is divided into a mechanical cutting process using a knife and a gas cutting process using a gas torch. In the cutting process, specimen cutting is performed for each process for material testing.

Looking at the specimen cutting operation of the cutting process as described above, in the mechanical cutting process, the specimen cutting operation is cut by automatic equipment, but in the gas cutting process, the operator cuts the specimen by manually operating the gas cutting device. The process is as follows.

First, when the heavy plate conveyed by the gas cutting process using a crane is aligned on the bed, the operator manually moves the torch mounted on the gas cutting device to the working position, and then cut the side surface of the heavy plate in the longitudinal direction.

Then, the front end portion of the heavy plate, that is, the cropped portion is cut in the width direction, and the width direction of the heavy plate is cut in accordance with the instructions to produce a plurality of products.

After the cutting process as described above, the operator manually adjusts the gas cutting device to cut the specimen to a certain size from the cropped crop part, and then places the cut specimen on the product using a lever or the like, and mounts it on the crane. The electromagnet is used to transfer to the specimen loading site.

However, in the process of placing the heavy specimens on the product by the operator, there is a case in which the specimen falls to the lower part of the bed, or there is a problem that the worker's safety accident occurs by the operator carrying the specimen on the bed.

In addition, it takes excessive working time due to manual work, and in the process of separating and transporting the specimen mounted on the upper surface of the product by using a crane, the product surface is damaged by the friction of the surface of the product and the quality of the product is reduced. In case of incurring or removing the flaw, there is a problem that additional work is required and the work efficiency is lowered.

Accordingly, the present invention is to solve the above problems, by installing a device that can cut and transport the specimen in the existing gas cutting device, by easily cutting and safely transport the specimen of various sizes, the safety of the operator The purpose is to provide a specimen cutting device that prevents accidents and increases work efficiency.
