Overhang roll overturning vertical demolding pipe manufacturing equipment

Abstract

The invention relates to overhang roll overturning vertical demolding pipe manufacturing equipment in the field of cement machinery. A pit is further arranged on the ground where the equipment is mounted in a cooperation manner and is used for mounting of a lifting platform, and an equipment body sequentially comprises a feeding machine, an overhang roll machine used in cooperation with the feeding machine and the lifting platform arranged in cooperation with the overhang roll machine and mounted in the pit. A positioning shifting fork is arranged at an outlet of the overhang roll machine in a cooperation manner, a ground guide rail is mounted on the ground at the rear end of the positioning shifting fork, a conveying trolley is correspondingly arranged on the ground guide rail, and lifting overturning machines are mounted on the two sides of the ground guide rail in a cooperation manner. The equipment body is further provided with overhang roll molds in a cooperation manner, and each overhang roll mold is correspondingly provided with a bottom tray. According to the equipment, the number of the overhang roll molds can be reduced, the auxiliary process time in the production process can be reduced, so that the production process becomes smooth, meanwhile, a vertical demolding process is adopted, immediate demolding is achieved after production of products is completed, the products can be naturally cured, the molds can be recycled, the production efficiency is improved, batch production of concrete pipelines is realized, and meanwhile the product quality is improved.

Description

technical field [0001] The invention relates to the field of cement machinery, in particular to a pipe making equipment. Background technique [0002] At present, domestic production equipment for reinforced concrete drainage pipes mainly includes vertical vibrating pipe forming pipe molds, hanging roller pipe making machines, centrifugal pipe making machines, mandrel vibration pipe making machines, and vertical radial extrusion pipe making machines. , There are several kinds of core rotary tube making machines. Among them, the vertical vibrating pipe forming pipe mold, hanging roller pipe making machine, and centrifugal pipe making machine have defects such as low production efficiency, high labor intensity, and high labor cost, and are not suitable for large-scale mass production; The production efficiency of the pipe machine has been improved, but the increase is not large, and there are certain defects in the product appearance quality, which need to be repaired later; ...

AI Technical Summary

Problems solved by technology

Among them, the vertical vibrating pipe forming pipe mold, hanging roller pipe making machine, and centrifugal pipe making machine have defects such as low production efficiency, high labor intensity, and high labor cost, and are not suitable for large-scale mass production; The production efficiency of the pipe machine has been improved, but the increase is not large, and there are certain defects in the product appearance quality, which need to be repaired later; the production efficiency of the vertical radial extrusion pipe machine has been greatly improved, but the equipment manufacturing cost is high, and at the same time The cost of changing the product specification is high, and the dynamic rolling head needs to be replaced 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. At the same time, pipe production has high requirements for concrete raw materials Higher, the particle size and fineness modulus of sand and stone have higher requirements, resulting in increased manufacturing costs. In addition, the impermeability and external pressure load of radial extrusion are not very good; The molding of the machine socket is not easy to control, the cost of equipment manufacturing is relatively high, and the appearance quality is not easy to control

At present, the most used pipe making equipment is the hanging roller pipe making machine. The product quality and appearance quality of the hanging roller pipe making machine have been recognized by the majority of users. The comprehensive product quality is in the forefront of all pipe making equipment, but due to the production efficiency Low level of automation, high labor cost and mold cost, so some users choose new equipment such as mandrel vibration pipe making machine, vertical radial extrusion pipe making machine, and rising core rotary pipe making machine; at the same time, there are The suspension roller pipe making process of the advanced suspension roller pipe making machine only has the main body of the suspension roller pipe making machine and the supporting mold and feeder. Usually the number of molds is determined according to the output. In normal production, more than 10 sets of molds are required. After the suspension roller is formed, the mold needs to be Put it together with the product in the steam curing pit for a period of time. After the concrete is initially solidified, the formwork can be removed. The utilization rate of the mold is low and the production efficiency is low.
