Punching machine sliding block guide structure with temperature compensation function

Abstract

The invention relates to a punching machine sliding block guide structure with a temperature compensation function. The punching machine sliding block guide structure with the temperature compensation function comprises a guide mechanism, a guide sleeve and a sliding block, wherein the sliding block and the guide sleeve are fixed. The punching machine sliding block guide structure with the temperature compensation function is characterized in that the guide mechanism comprises a guide rod and a limiting stopper, wherein the guide sleeve is movably arranged on the guide rod in the vertical direction; and the guide rod is movably arranged on the limiting stopper in the left-right direction. The guide mechanism can realize the temperature compensation function, and the guide rod can correspondingly move along with expansion and contraction of the sliding block, so that the problem of interference between the guide rod and the guide sleeve is avoided. In addition, the problem of part interference caused by thermal expansion and cold contraction of the sliding block is solved through the design of a mechanical structure, and compared with an existing punching machine provided with a heat conduction system, the manufacturing cost and the manufacturing difficulty of a punching machine can be effectively controlled.

Description

technical field [0001] The invention relates to the field of punching machines, in particular to a sliding block guide structure of a punching machine with a temperature compensation function. Background technique [0002] Punching machine, that is, stamping press, in production, the stamping process saves materials and energy compared with traditional machining, has high efficiency, does not require high technical requirements for operators, and can make mechanical processing through various mold applications. These advantages of the products achieved, so the use of punching machines is becoming more and more extensive. [0003] The stamping operation of the punch press is usually realized by moving up and down the slider, and in order to guide the moving direction of the slider, a guide mechanism is generally provided on the punch press. However, during the stamping process and after the stamping is completed, the temperature of the slider will change greatly, and due to ...

Problems solved by technology

[0005] However, the structure of the heat conduction system itself is relatively complicated, and setting up the heat conduction system will inevitably lead to a significant increase in the manufacturing cost of the punch press

In addition, in addition to setting up a heat conduction system, accurate calculations must be made in conjunction with the thermal conductivity of each part to ensure that the degree of thermal expansion and contraction of the whole machine remains consistent, which is difficult to achieve
