A kind of rising core rotary vibration extrusion forming pipe making machine

Abstract

The invention provides a core-lifting rotary type vibrating extrusion forming tubing machine. According to the core-lifting rotary type vibrating extrusion forming tubing machine, an automatic core lifting mode is adopted to an inner die, a special forklift demoulding mechanism is adopted to outer dies for quick die opening and die assembly, the outer dies can be quickly arranged in place through a rotary platform, and production efficiency is improved. The core-lifting rotary type vibrating extrusion forming tubing machine comprises a rack, a feeding mechanism, a rolling plate, the rotary platform, the outer dies, a rotary material uniforming mechanism, a vibrating mandrel and the inner die. The outer dies are arranged on the rotary platform which drives the outer dies to rotate, and the rotary platform is located above the inner die. The rotary material uniforming mechanism is arranged on the top of the inner die, the vibrating mandrel is arranged in the inner die, the inner die ascends and descends relative to the rack through a lifting mechanism, and the inner die enters the outer dies to form a tube cavity. The feeding mechanism is used for feeding materials to the tube cavity, the rolling plate is arranged on the rack and ascends and descends, and the rolling plate is used for rolling concrete products on the upper portion of the tube cavity. By means of the core-lifting rotary type vibrating extrusion forming tubing machine, auxiliary procedure time consumed in the production process is shortened, and work efficiency is improved.

Description

technical field [0001] The invention relates to pipe-making and forming production equipment for concrete structure pipelines, in particular to a pipe-making machine for core-raising rotary vibration extrusion forming. Background technique [0002] At present, the domestic production equipment for reinforced concrete drainage pipes mainly includes vertical vibrating pipe forming pipe molds, suspension roller pipe making machines, centrifugal pipe making machines, common mandrel vibration pipe making machines and vertical radial extrusion pipe making machines. Several kinds of machines. Among them, the vertical vibrating pipe forming pipe mold, suspension roller pipe making machine, and centrifugal pipe making machine have defects such as low production efficiency, high labor intensity, high labor cost, and high energy consumption, and are not suitable for large-scale mass production. ; The production efficiency of the ordinary mandrel vibration pipe making machine has been ...

AI Technical Summary

Problems solved by technology

Among them, the vertical vibrating pipe forming pipe mold, suspension roller pipe making machine, and centrifugal pipe making machine have defects such as low production efficiency, high labor intensity, high labor cost, and high energy consumption, and are not suitable for large-scale mass production. ; The production efficiency of the ordinary mandrel vibration pipe making machine has been improved, but the improvement is not large, and there are certain defects in the appearance of the product, which needs to be repaired later; the production efficiency of the vertical radial extrusion pipe making machine has been greatly improved, but the equipment The manufacturing cost is high, and the cost of changing the product specification is high at the same time. It is necessary to replace the dynamic rolling head according to the inner diameter of the pipe, and the socket part of the produced concrete pipe is not easy to be dense, and it is prone to cracks, which will bring trouble to subsequent production. The production has higher requirements for concrete raw materials, and the particle size and fineness modulus of sand and stone have higher requirements, resulting in increased manufacturing costs
