Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy pipe demoulding devices, in particular to a demoulding device for seamless pipes extruded by a forward extruder. Background Art

[0002] Aluminum alloy forward extruders are generally suitable for the production of extruded profiles, bars and seamed pipes, with high production efficiency and short auxiliary time. Seamless pipes are generally extruded using reverse extruders, which require long auxiliary time for upper and lower dies.

[0003] At present, the existing pipe demoulding device can effectively and quickly realize the demoulding of the extruded pipe, speed up the demoulding efficiency, avoid scratching the surface of the membrane material, and realize efficient, rapid and complete demoulding. The pipe demoulding device adopts hydraulic control, and the opposing clamping jaws can quickly and accurately reach the working position under the drive of the clamping cylinder. There is no shaking during the movement, which avoids scratching the pipe. The working process is more stable, and the opposing clamping jaws are prevented from being misaligned with each other, which causes the pipe to deform under the action of extrusion. At the same time, the cylinder is smaller and does not take up too much space. The pipe demoulding device adopts opposing clamping jaws to realize demoulding of the pipe, reduces manual workload, and improves production efficiency. After the opposing clamping jaws clamp the pipe, the demoulding cylinder drives the bottom plate forward to realize demoulding of the pipe.

[0004] For example, the authorization announcement number CN220804989U discloses a demoulding device for extruding seamless pipes from a forward extruder, which includes: a bracket, which is mounted at the discharge port of the front beam of the extruder; a base plate, which is slidably mounted on the bracket; a clamping cylinder, which has two clamping cylinders mounted on the base plate, and the two clamping cylinders are respectively arranged on the left and right sides of the discharge port; a clamping jaw, with a clamping jaw mounted on the output end of each clamping cylinder, and the clamping jaw is used to clamp the extruded pipe; a demoulding cylinder, which is parallel to the axis of the discharge port, the cylinder body of the demoulding cylinder is mounted on the bracket, the cylinder rod head of the demoulding cylinder is connected to the base plate, and the demoulding cylinder is used to drive the base plate closer to or away from the discharge port to achieve the demoulding function. However, in such a demoulding device for extruding seamless pipes from a forward extruder, the clamping jaws press the two sides of the aluminum alloy pipe, which easily causes the two sides of the aluminum alloy pipe to be squeezed and deformed, and the telescopic length of the demoulding cylinder is limited, resulting in a short demoulding length of the aluminum alloy pipe.

Therefore, the existing technology needs to be improved. Utility Model Content
