Problems solved by technology

It takes time to start and stop the product, mold lifting and cooling process, resulting in low product output and high processing cost
And every time there are waste products (head material) during the start-up and shutdown process, causing unnecessary loss
[0003] Secondly: the traditional carat tube production process is complicated, natural gas heating, start-up winding forming, cutting and repairing, fan cooling, trimming, cloth and other processes, the labor cost of starting up a production line is relatively large
Moreover, natural gas is needed to heat the mold. In some places where natural gas is inconvenient, electric heating with a power of tens of kilowatts is used, and the cost of power loss is high.
[0004] Thirdly, the product quality is not stable, and each process is mainly manual operation. Cutting is to control the size of the bearing and socket of the carat tube product. The electric fuse is mainly heated to melt the raw materials to achieve the fusion of the socket interface. The number of electric heating wire cloth and the effect of embedding determine the quality of product connection

Embodiment 1

[0043] A new continuous production process of helically wound carat tubes, the detailed steps are:

[0044] The first step is to set the production process temperature of the main engine. The barrel process temperature of the main engine is set to 165°C, and the mold process temperature of the runner machine of the main engine is set to 175°C. The mixing and heating extrusion operations are performed, and the mold of the runner machine is used to Extruded round tube;

[0045] The second step is to start the auxiliary machine to extrude the flat belt, and wrap the flat belt on the forming drum mold to complete the winding of the round tube, and then complete the winding of the socket and the socket. According to different specifications, the width and thickness of the flat belt are inconsistent, and the flat belt The belt mainly plays the role of inner and outer walls during the winding process;

[0046] The third step is to observe whether the product pitch meets the required...

Abstract

The invention relates to a novel spiral wound krah pipe continuous production technology and device. The novel spiral wound krah pipe continuous production technology comprises the following technological steps of material stirring operation, heating extrusion, extrusion of circular pipes, extrusion of flat strips, winding of the flat strips, winding of the circular pipes, winding of bells and spigots, cooling, cutting, shape modification of the bells and the spigots, inspection and storage. The impact resistance of spiral wound krah pipes produced through the novel spiral wound krah pipe continuous production technology and device is improved, and continuous production is achieved.

Description

technical field [0001] The invention relates to the technical field of pipe production, in particular to a novel continuous production process and equipment for spirally wound carat pipes. Background technique [0002] The traditional winding reinforced structure wall tube (carat tube) is wound and formed by a 6-meter-long mold. Every time a 6-meter-long carat tube is produced, the extruder (production equipment) needs to be stopped, and then the mold is lifted to the cooling rack. , using fan cooling, when the ambient temperature reaches 35 degrees in summer, the cooling speed of the product is very slow, and the power loss is also large. Cooling a mold requires 4 cooling fans. It takes time to start and stop the product, mold lifting and cooling process, resulting in low product output and high processing cost. And every time there are waste products (head material) in the process of starting and stopping, causing unnecessary loss. [0003] Secondly: the traditional cara...
