Abstract
The utility model discloses a material containing square basket for preventing heat treatment deformation of thin-wall gears. The material containing square basket structurally comprises a material containing basket body and partition plates, wherein the material containing basket body is in the shape of an uncovered rectangular box; the partition plates are in the shape of rectangular plates; and the material containing basket body and the partition plates are made of stainless steel wires. The annual output of motorcycles of China is the highest in the world, and various specifications of thin-wall gears occupy a large proportion. The heat treatment quenching deformation of thin-wall gears is a common phenomenon of manufacturers. Due to the difference of material containing equipment and part placement modes, the proportion of quenching deformation is greatly different for same heat treatment furnaces and same technical parameters. Without special equipment for avoiding over-large heat treatment quenching deformation, thin-wall gear products are difficult to process and manufacture. As special equipment for different specifications of thin-wall gear products with high suitable layers, the material containing square basket can ensure the effective utilization of the volumes of heat treatment furnaces and facilitate the quality control on heat treatment products.
Description
Technical field
The present invention relates to the thermal processing equipment of thin-walled gear, is a kind of for the charge side's basket that improves thin-walled gear thermal treatment quality specifically.
Background technology
Along with the raising of living standards of the people, motorcycle has become a kind of important vehicles in people's daily life, and China's motorcycle annual production leaps to the first in the world, and wherein all size thin-walled gear occupies larger proportion.Described thin-walled gear adopts medium carbon alloy steel or low-carbon alloy steel to make, and requires necessary carburizing or nitriding in order to satisfy hardness and wear resistance, can improve wear resistance and the fatigue resistance of thin-walled gear part.At present, the distortion of thin-walled gear heat-treatment quenching is manufacturer's universal phenomenon, identical heat treatment furnace, same technical parameter, because the difference of charge equipment, part disposing way, the ratio difference of its quenching strain is very big, put if pile up arbitrarily, after the quenching, can cause most of defective; Gear takes the punching axle to quench (wearing sugared ball formula), and when the useful volume that mandrel takies the thermal treatment burner hearth influenced output, defective ratio also reached 3 percent.Because the equipment in order to the thermal treatment charge mostly is simple welding charge basket, do not avoid excessive heat-treatment quenching distortion at the gear product design charge equipment of differing materials different size, brought difficulty for the processing and manufacturing of thin-walled gear product.It is a kind of for the charge side's basket specific equipment that improves thin-walled gear thermal treatment quality that the present invention can provide, and reached comparatively desirable effect.
Summary of the invention
The present invention is directed to the technological deficiency that existing thermal treatment charge equipment exists, a kind of charge side's basket that improves thin-walled gear thermal treatment quality is provided.
The present invention is achieved through the following technical solutions:
A kind of charge side's basket that prevents thin-walled gear heat treatment deformation, its structure comprises charge basket and dividing plate; It is rectangular box-like that described charge basket is shaped as uncovered; Described dividing plate is the rectangle sheet; Charge basket and dividing plate adopt Stainless Steel Wire.China's motorcycle annual production occupies first place in the world, and wherein all size thin-walled gear occupies larger proportion.At present, the distortion of thin-walled gear heat-treatment quenching is manufacturer's universal phenomenon, identical heat treatment furnace, same technical parameter, because the difference of charge equipment, part disposing way, the ratio difference of its quenching strain is very big, put if pile up arbitrarily, after the quenching, can cause most of defective; Gear takes the punching axle to quench, and when the useful volume that mandrel takies the thermal treatment burner hearth influenced output, defective ratio also reached 3 percent.Because the equipment in order to the thermal treatment charge mostly is simple welding charge basket, do not have producer to avoid excessive heat-treatment quenching distortion at the gear product design charge specific equipment of differing materials different size, brought difficulty for the processing and manufacturing of thin-walled gear product.It is a kind of for the charge side's basket specific equipment that improves thin-walled gear thermal treatment quality that the present invention can provide, can design charge side's basket size at the thin-walled gear product of the suitable floor height of different size, guarantee that the heat treatment furnace volume effectively utilizes, the temperature that charge basket and dividing plate adopt Stainless Steel Wire to have and be suitable for heat treated article is controlled and quality-guarantee.
Beneficial effect of the present invention is:
A kind of charge side's basket that prevents thin-walled gear heat treatment deformation, its structure comprises charge basket and dividing plate; It is rectangular box-like that described charge basket is shaped as uncovered; Described dividing plate is the rectangle sheet; Charge basket and separator material adopt Stainless Steel Wire.China's motorcycle annual production occupies first place in the world, and wherein all size thin-walled gear occupies larger proportion.At present, the distortion of thin-walled gear heat-treatment quenching is manufacturer's universal phenomenon, identical heat treatment furnace, same technical parameter, because the difference of charge equipment, part disposing way, the ratio difference of its quenching strain is very big, put if pile up arbitrarily, after the quenching, can cause most of defective; Gear takes the punching axle to quench, and when the useful volume that mandrel takies the thermal treatment burner hearth influenced output, defective ratio also reached 3 percent.Because the equipment in order to the thermal treatment charge mostly is simple welding charge basket, do not avoid excessive heat-treatment quenching distortion at the gear product design specialized charge equipment of differing materials different size, brought difficulty for the processing and manufacturing of thin-walled gear product.The present invention can provide a kind of can design charge side's basket size at the suitable floor height that stacks of different size gear product for the charge side's basket specific equipment that improves thin-walled gear thermal treatment quality, and favourable heat treatment furnace volume effectively utilizes; Charge basket and separator material adopt Stainless Steel Wire, guarantee being heated evenly simultaneously of heat treated article, are of value to the quality control of product.Adopt the technology of the present invention can guarantee that the defective scale dimension of heat-treatment quenching product is held in more among a small circle, has reached comparatively desirable effect.
