Summary of the invention
The technical problem that the utility model will solve provides the flexible positioning and clamping mechanism of a kind of hot former lower platform; The positioning and clamping mechanism that should stretch is not only simple in structure; Hot forming workbench good stability, secondary difficult inefficacy of slide block; And improved the positioning accuracy of initial point of withdrawing, and reliable and stable branch die drawing power is provided.
For overcoming the above problems; The concrete technical scheme of the utility model is following: a kind of hot former lower platform positioning and clamping mechanism that stretches; Comprise hydraulic press lathe bed, guide rail, slide block, lifting cylinder and lower platform; Between lower platform and hydraulic press lathe bed, carry out transmission, on the lifting cylinder, be provided with the side leading truck, the gathering sill sliding-contact of the other end of side leading truck and guide rail through hydraulic motor, reductor, gear and tooth bar; Catercorner direction is provided with two positional cylinders in the hydraulic press lathe bed, on lower platform, is provided with two circular holes, and its position is corresponding respectively with the position of two positional cylinders; In the hydraulic press lathe bed, become four rotary oil cylinders of distributed rectangular, on lower platform, be provided with four strip holes, its position is corresponding respectively with the position of two rotary oil cylinders.
The flexible positioning and clamping mechanism of this hot former lower platform has adopted positional cylinder, and locating accuracy is improved, and can play corrective action to the deflection of lower platform simultaneously; Adopted rotary oil cylinder, can compress the lower platform base plate, applied downward active force to lower platform, with balance withdrawing pattern pulling force, lower platform just can provide enough branch die drawing power like this.
