Problems solved by technology
In the diameter reducing process, the device mainly adopts the conical traveling mandrel to cooperate with the traveling mandrel, and the conical traveling mandrel is blocked by the cooperation of the conical traveling mandrel and the fixed mold box, so as to realize the control of the traveling mandrel. Positioning to achieve the purpose of stretch forming; in the process of forming aluminum tubes, the forming and eye-catching are carried out separately, and are completed on two chain machines respectively. The processing method is as follows: the processing raw material is a fixed-length round aluminum The aluminum tube sleeve passes through the outer mold on the fixed core, and the tube head is clamped by the jaws of the trolley on the chain drawing machine and pulled through the forming outer mold to become a square tube. This processing method is intermittent production, and the yield is low. The labor intensity is high, the production efficiency is low, and it affects the forming quality of the aluminum tube, so it is difficult to realize the automatic control of the equipment

Embodiment Construction
[0018] According to attached figure 1 It can be seen that the present invention specifically introduces a continuous molding method for hollow aluminum spacers, which is characterized in that the steps of the molding method are as follows:
[0019] a. Continuous molding of aluminum tubes: the free end of the round aluminum tube 1 to be processed penetrates the swimming core 2, so that the round aluminum tube 1 penetrates the outer mold 3, and is continuously processed and formed by the forming machine 4 to form a square hollow Aluminum tube;
[0020] b. Continuous piercing of the aluminum tube: the square hollow aluminum tube is pulled by a tractor and enters the piercing machine 9, and the upper surface of the square hollow aluminum tube is continuously pierced;
[0021] c. Continuous straightening of aluminum tubes: The square hollow aluminum tubes after being pierced are pushed into the straightening machine 13 by the tractor, and the curved parts are continuously straight...

The invention discloses a hollow aluminium division bar continuous moulding method. A round aluminium tube sequentially passes through a moulding machine, a traction machine, a hole punching machine, a straightening machine and a cutting machine, and four-step processing, namely continuous moulding, continuous hole punching, continuous straightening and cutting based on a specified length is completed, thus the hollow aluminium division bar meeting the demands of engineering can be processed, and continuous production can be completed while only one power driver is required in the entire process. By applying the method disclosed by the invention, continuous production on the hollow aluminium division bar can be realized, the production speed is fast, the yield is high, the processing efficiency is improved, the labour intensity of workers is reduced, the product quality is stable, and automatic control can be realized.
Description
technical field [0001] The invention belongs to the technical field of metal plastic processing and molding, in particular to a continuous molding method for hollow aluminum spacers. Background technique [0002] In the prior art, aluminum tubes are subjected to diameter reduction processing and continuous drawing, and the swimming core drawing method is mainly used to realize processing such as diameter reduction, wall thickness reduction, and forming of aluminum tubes. In the diameter reducing process, the device mainly adopts the conical traveling mandrel to cooperate with the traveling mandrel, and the conical traveling mandrel is blocked by the cooperation of the conical traveling mandrel and the fixed mold box, so as to realize the control of the traveling mandrel. Positioning to achieve the purpose of stretch forming; in the process of forming aluminum tubes, the forming and eye-catching are carried out separately, and are completed on two chain machines respectively....
