Abstract

The invention relates to an automatic cooling system after pipe extrusion, which is characterized by comprising a pipe support seat, a pipe support roller, a guide rail and a water cooling mechanism; the automatic cooling system after pipe extrusion in the present invention adopts the outer end of the extruder. The movable pipe support seat is set up, and the spray of the water cooling mechanism is used to realize the cooling of the pipe material on the pipe support seat. In addition, the pipe support roller set on the pipe support seat can make the pipe material roll in multiple directions during spraying. angle for cooling.

Description

Automatic cooling system of pipe extrusion die

Technical Field

The invention relates to the field of pipe cooling, in particular to an automatic cooling system for a pipe extrusion die.

Background

The polyethylene plastic steel pipe is a novel non-pressure drainage pipe, which is a structural wall drainage pipe formed by processing a composite strip material by using High Density Polyethylene (HDPE) or Medium Density Polyethylene (MDPE) plastic and a carbon structural steel cold-rolled steel strip (such as Q195) as raw materials in a continuous extrusion mode, and then winding and plastic welding. The composite pipe has the advantages of corrosion resistance, light weight, simple and convenient installation, large flow, long service life (50 years) and the like, can replace the pipe made of high-energy-consumption materials (cement, cast iron, ceramic and the like), and belongs to an environment-friendly green product.

The general pipe adopts when extruding that the mouth of extruding sets up the water jet and the scope of water jet is little, and the cooling effect is poor, leads to the big easy deformation of internal stress of pipe after extruding.

Disclosure of Invention

The technical problem to be solved by the invention is to provide an automatic cooling system for a pipe extrusion die, which can solve the problem of small water spray range and poor cooling effect caused by cooling a general pipe at the pipe orifice of an extruder.

In order to solve the technical problems, the technical scheme of the invention is as follows: the utility model provides a tubular product automatic cooling system after extruding which innovation point lies in: the device comprises a pipe supporting seat, a pipe supporting roller, a guide rail and a water cooling mechanism;

the bottom end face of the pipe supporting seat is provided with a pulley, the guide rail is arranged below the winding roller supporting seat and matched with the pulley of the winding roller supporting seat, and the bottom end of the winding roller supporting seat is driven by a gear-chain pair driven by a motor to move along the guide rail in the horizontal direction;

the pipe supporting roller comprises a fixed block and a movable roller; the fixed blocks are arranged on two side edges of the top end of the pipe supporting seat, and round roller mounting holes are formed in the fixed blocks; the movable roller is formed by three round rollers in a triangular shape, two ends of each round roller are respectively connected by a triangular connecting plate, the round rollers can rotate around the triangular connecting plates, and one round roller is connected with a round roller mounting hole on the fixed block and rotates around the round roller mounting hole;

the water cooling mechanism comprises a servo motor, a hydraulic pump, a spray pipe, a liquid storage tank and a liquid pumping pipe; the output end of the servo motor is connected with a hydraulic pump, one end of the liquid pumping pipe extends into the liquid storage tank, and the other end of the liquid pumping pipe is connected to the hydraulic pump; the spray pipe is horizontally arranged and extends to the upper part of the pipe supporting seat, a high-pressure spray head is arranged at one end of the spray pipe, and the other end of the spray pipe is connected to the output end of the hydraulic pump.

The invention has the advantages that:

1) in the automatic cooling system after the pipe is extruded, the movable pipe supporting seat is arranged at the outer end of the extruder, the pipe is cooled on the pipe supporting seat by spraying of the water cooling mechanism, and in addition, the pipe supporting roller arranged on the pipe supporting seat can roll the pipe in the spraying process, so that the pipe can be cooled in multiple directions and multiple angles.

Drawings
