Tube bending machine applied to steel tube production

Abstract

The invention discloses a tube bending machine applied to steel tube production. The tube bending machine comprises a machine frame and a working table. The working table is located on the machine frame. A bent guide rail and a bent table are arranged on the working table. A clamping device is connected between the bent table and the bent guide rail and comprises clamping control chambers and clamping bases. The clamping control chambers comprise the inner clamping control chamber and the outer clamping control chamber. The clamping bases comprise the inner clamping base and the outer clamping base. A bent sliding block is arranged on the bent guide rail, the upper end of the bent sliding block is connected with the outer clamping control chamber, and the outer clamping control chamber is fixedly installed on the bent sliding block. The inner clamping base is connected with an inner arc inclined rail. The outer clamping base is connected with an outer arc inclined rail. A rotating shaft is arranged at the lower end of the bent table and connected with a power driving device. Through the clamping device, the inner clamping base and the outer clamping base cooperate to clamp a tube to be bent so as to make preparations for bending the tube to be bent; through the bent guide rail and the bent sliding block, the outer clamping chamber can work along with the outer clamping base in the process of bending the tube to be bent.

Description

technical field [0001] The invention relates to a pipe bending processing equipment, in particular to a pipe bending machine used in the production of steel pipes. Background technique [0002] Pipe bending machines can be roughly divided into CNC pipe bending machines, hydraulic pipe bending machines and so on. Pipe benders are mainly used for bending steel pipes and other materials, and play an important role in the laying and repair of pipes in boilers, bridges, ships, furniture, decoration, etc. Due to the limitation of the mold, the arc cannot be bent at will. For example, if it is a perfect circular mold, the curved arc can only be a perfect circle, but not an elliptical arc. If you want to bend other arcs, you can only change the mold. It causes the waste of materials and the increase of cost, and also reduces the production efficiency. In addition, due to the influence of the structure, the traditional pipe bending machine can only process flat products, the effici...

Pipe benders are mainly used for bending steel pipes and other materials, and play an important role in the laying and repair of pipes in boilers, bridges, ships, furniture, decoration, etc. Due to the limitation of the mold, the arc cannot be bent at will. For example, if it is a perfect circular mold, the curved arc can only be a perfect circle, but not an elliptical arc. If you want to bend other arcs, you can only change the mold. It causes waste of materials and increases in cost, and also reduces production efficiency.

In addition, due to the influence of the structure, the traditional pipe bending machine can only process flat products, the efficiency is low, the product quality is unstable, and it is not suitable for mass production; the scope of use is small, and it cannot meet the existing diversified products, such as steel pipes and clamping devices. The contact point with the bending table is prone to slipping, which affects the normal bending and bending accuracy of the steel pipe
