Description
Technical Field
The invention relates to the technical field of forging piece polishing, in particular to a polishing device for high-strength forging piece production and preparation.
Background
Forging is a process in which a forging machine is used to apply pressure to a metal blank to plastically deform it to obtain a forging having specific mechanical properties, shape and size. The forging process generally includes forging, reheating, and heat treatment, wherein the forging is to apply pressure to a metal blank by using a forging hammer, a die forging hammer, a hydraulic press, or the like, so as to cause plastic deformation. Forging can be classified into free forging, which is forging performed on a planar or simple profile anvil surface, and die forging; swaging is forging in a die having a shape and size.
The forging process can be used to manufacture a variety of metal articles such as automotive parts, aerospace parts, mechanical parts, engineering mechanical parts, and the like. The forging not only can manufacture the forge piece with complex appearance and accurate size, but also can optimize the internal structure of metal, eliminate cast structure and segregation, refine grains, thereby remarkably improving the mechanical properties of the forge piece, such as strength, plasticity, toughness and the like.
In the production and preparation process of the high-strength forging piece, polishing is an important process, and has an important effect on improving the surface quality and precision of the forging piece. The polishing is a processing method for removing surface burrs, oxide scales and other defects and improving surface finish and dimensional accuracy by using an abrasive material or a grinding tool to conduct micro-cutting and plastic deformation on the surface of a workpiece. After forging, the surface of the forging piece is usually provided with a certain amount of defects such as oxide skin, burrs, folds and cracks, and the defects need to be removed by polishing. In addition, some forgings require further improvement in surface accuracy and finish, and also require grinding.
At present, the forging piece is polished mainly by adopting two modes of manual polishing and mechanical polishing. The manual polishing mainly comprises the steps of polishing the surface of a forging piece by using an operator to hold a grinding tool such as a grinding wheel, and has the problems of high labor intensity, poor working environment, low polishing efficiency, poor product consistency and the like, and is gradually replaced by mechanical polishing. The mechanical polishing adopts special polishing equipment to automatically polish the forge piece, so that the production efficiency and the consistency of product quality can be greatly improved, and the mechanical polishing becomes a main polishing mode of modern forging enterprises.
However, the existing mechanical polishing equipment still has some defects when polishing the forged piece:
a large amount of metal dust is generated in the polishing process, and most of the dust is tiny particles and is easy to diffuse into the air. The diffused dust in the workshop not only pollutes the environment, but also can be inhaled into the respiratory tract by workers, thereby causing harm to the health. Prolonged contact and inhalation of metal dust can lead to occupational diseases such as pneumoconiosis.
Dust generated by polishing can also cause certain damage to equipment. When a large amount of dust enters the fit clearance of moving parts such as a bearing, a gear and a screw rod, abrasion is increased, the service life of parts is shortened, and even equipment is blocked and cannot operate. In addition, dust build-up can also cause equipment failure and safety hazards.
When forging piece volume is great, the shape is complicated, current equipment of polishing is difficult to carry out even, comprehensive polishing to its each surface, especially to special positions such as some indent curved surfaces, narrow recess, and the blind area of polishing is more, influences the effect of polishing.
Most mechanical polishing equipment is not perfect in protective measures, and hidden danger of dust leakage exists. Even if some simple dustproof devices are arranged on the equipment, in actual use, part of dust can not overflow from the gaps, and the workshop environment is polluted.
Effective cleaning measures are lacking for dust collected in the polishing process. Some devices, although equipped with dust removal devices, fail to clean the collected dust in time, resulting in dust build-up in the dust collector. When the capacity of the dust remover is saturated, secondary diffusion of dust is caused.
