Based on the above reasons, laser cutting technology emerged in sheet metal workshop. The biggest characteristic of laser cutting technology is that it can be processed without mould. The use of laser cutting and blanking saves the use of a large number of molds, thus shortening the production time and reducing the product cost. Laser processing technology has better advantages in the market. It is very conducive to the production of a variety of small batch products and subsequent large-scale production of products.
The laser of sheet metal workshop is a kind of coherent light source with high brightness, precise direction, monochromatic and parallel, and its energy density is very high. When the focused laser beam can produce high temperature on the irradiated material. Under the action of tens of thousands of degrees of high temperature, no matter how hard the material is, it will immediately melt and evaporate, generate shock wave, melt and remove the material. In the process of laser material processing, local heating is essentially melting to form vaporized material.
The laser cutting technology of sheet metal workshop can process the parts which are difficult to be realized by traditional methods. For example, for steel parts with large boxes, many holes of different sizes need to be machined, which is impossible for traditional machining methods, and laser cutting technology can meet these requirements. Even if the same parts are processed, laser cutting technology has the advantages of high precision and short time, so the products have strong market competitiveness.
Laser cutting in sheet metal workshop has a strong flexibility in two-dimensional plane. When in use, the cutting head of the workpiece fixed cutting machine is in the moving state, which will not cause the dead angle of processing. Accordingly, the utilization rate of processing materials is improved, the micro connection of the equipment can be omitted, and the laser cutting processing equipment is simpler. The computer control system of laser cutting equipment is controlled as a whole, which can be processed without controlling parts, setting mould and designing processing route. Therefore, the preparation time of laser cutting technology can be greatly shortened. Laser cutting equipment has the advantages of fast processing speed, short processing time and high production efficiency.
The processing steps of sheet metal processing parts include: product preliminary test, product trial production and product batch production. In the trial production stage of product processing, the customer shall be contacted in time, and the batch production of the product shall be carried out after obtaining the corresponding processing evaluation.
The sheet metal workshop shall communicate and discuss with customers in a timely manner, and the determined contents include the technical objectives required by the product, the contract of technical confidential contents, product patents, the management of design schemes and drawings, the treatment of relevant technologies and the specific time limit for product delivery. The contract shall be made accordingly to clarify the technical authority and respective rights. The sheet metal workshop shall keep confidential the technical content of customers in the process of processing, so as to avoid the damage of its products due to infringement.
After the technicians accept the Commission of batch trial production or production, they shall process according to the standard required by the contract. In order to ensure the professional quality of the technicians in the sheet metal workshop, the work should be completed in a fast way to meet the needs of customers.
The technicians in the sheet metal workshop should be familiar with the characteristics of the laser cutting and processing equipment, understand the status of the laser cutting and processing equipment, and do a good job in equipment maintenance. The device is operating at its best. In the process of laser cutting, visual inspection should be carried out in time, including macro observation and micro observation, observing the section shape of laser cutting, and making corresponding information records. In the laser cutting center of the laser cutting generator, in the laser cutting area, the computer control area, the raw material feeding area, the finished product blanking area and the working area of the material conversion device, it is necessary to arrange technicians to operate in the raw material feeding area and the finished product blanking area, and other working areas can be automatically controlled by the computer.
