AI Technical Summary
In the existing technology, unloading is difficult during the pipe shrinking process, which leads to increased friction, increased unloading difficulty, affects production efficiency and product quality, and easily damages the pipe fittings.
A tube shrinking device including a mold base, a drive assembly, a shrinking device, and an unloading device is designed. The unloading device enables automated unloading. The unloading pipe and pusher push the tube out of the shrinking device. Combined with the cooperation of the drive assembly and the moving assembly, a fast and accurate unloading operation is achieved.
It achieves a fast and automated unloading process, reduces pipe damage, improves production efficiency and product quality consistency, reduces labor intensity and scrap rate, and extends the service life of the equipment.
