Description

A kind of well formula tempering stove

Technical field

The utility model relates to five metals raw material disposal field, and in particular, the utility model relates to well formula tempering stove.

Background technology

Equipment for Heating Processing very widely applied by tempering stove, when tempering stove is applied in fastening piece manufacture field, be generally used for and small-sized fastening piece is processed, and when carrying out the process of disposable great quantity of small part, be easy to occur that section components is heated inequality, effect is caused not add, overcome the above problems and generally have two thinkings, one be each position in tempering stove is heated evenly, two is directly carry out temper to starting material, relative to the former, the latter has with low cost, the advantage that production efficiency improves.

In Investment in fastener industry, starting material are generally the coil of metal material, due to the shape of coil itself, be easy to the thermally equivalent realizing each several part, and can a large amount of coil of disposable process, greatly improving production efficiency, reduce the number of times that goes into operation of tempering stove, realize the saving of resource, on this basis, the inter-process chamber of tempering stove is larger, more can realize above beneficial effect.

Tempering stove can be divided into well formula and Che Shi two kinds, the former application is comparatively extensive, and well formula tempering stove is according to its volume size, large-scale and small-sized tempering stove two class can be divided into, for large-scale tempering stove, its greater weight body of heater correspond to the very large bell of weight, and the bell of large quality can only carry out folding with arm, in prior art, also there is following problem in well formula tempering stove:

Arm is generally placed in tempering stove side, and during opening and closing bell, fixed pulley for supporting can be subject to oblique power, for a long time in the past, the generation of whole suspension arm mechanism just can be made to the sidesway in bell direction, when sidesway once produce, stay cord just can not keep vertically when folding, make oblique pulling force become large, further, increase the degrees of offset of arm at faster speed, have a strong impact on the work-ing life of tempering stove.
