Anti-deformation device for flame cutting

Abstract

The invention discloses a flame cutting deformation preventive device which comprises a fixing platform (1), supporting devices and clamping devices arranged on the fixing platform (1). Each clamping device comprises a horizontal cylinder (3), a rotary cylinder (4) and a clamping block (5), the horizontal cylinder (3) is fixedly arranged on the fixing platform (1), the rotary cylinder (4) is fixedly arranged on a piston rod A (6) of the horizontal cylinder (3), and the clamping block (5) is fixedly connected with a piston rod B (9) of the rotary cylinder (4). The flame cutting deformation preventive device has the advantages that grooves on two surfaces of each of four edges of a plate can be machined after the plate is clamped at one step, the production efficiency is high, the labor intensity of operators is reduced, and requirements of batch production can be met; the machining precision is high, and the quality of the plate is guaranteed; and deformation of the plate due to repeated clamping is prevented.

Description

technical field [0001] The invention relates to a clamping device for cutting, in particular to an anti-deformation device for flame cutting. Background technique [0002] When cutting plates, clamps are usually used to clamp and position the plates at present, and after marking and aligning, the flame cutting machine performs cutting and beveling processing. After straightening, the flame cutting machine is used to cut the second edge. For the plate that needs to be cut on all four edges, it needs to be clamped four times, and every time it needs to be straightened, the production efficiency is low, and the labor intensity of the operator is high. , and due to repeated clamping, the processing error of the plate is large, the pass rate is low, and the repeated clamping will also cause deformation of the plate. Therefore, the existing fixtures cannot meet the needs of high-precision and mass production, which restricts the improvement of production efficiency. Contents of ...

[0002] When cutting plates, clamps are usually used to clamp and position the plates at present, and after marking and aligning, the flame cutting machine performs cutting and beveling processing. After straightening, the flame cutting machine is used to cut the second edge. For the plate that needs to be cut on all four edges, it needs to be clamped four times repeatedly, and it needs to be straightened every time. The production efficiency is low and the labor intensity of the operator is high. , and due to repeated clamping, the processing error of the plate is large, the pass rate is low, and the repeated clamping will also cause deformation of the plate. Therefore, the existing fixtures cannot meet the needs of high-precision and mass production, which restricts the improvement of production efficiency.
