Extrusion-type cement pipe making machines are a type of cement pipe making equipment, selected and used according to actual needs. Operators of the pipe making machine are required to be familiar with the equipment's structure and understand the relevant operating methods. How much do you know about the production process of extrusion-type pipe making machines? Let's take a look together.

Introduction to the Reinforcing Steel Cage Fabrication Production Process of Extrusion-Type Cement Pipe Making Machines:

1. On the reinforcing steel cage forming frame, according to the reinforcement requirements in the drawings, use a horizontal cement pipe-making machine to adjust the outer diameter of the forming frame according to the actual inner diameter of the circumferential reinforcement of the reinforcing steel cage to be produced. Mark the equidistant points on the support frame according to the pitch of the circumferential reinforcement.

2. Rotate the forming frame and wind the circumferential reinforcement onto the forming frame according to the pitch marks. Ensure the accuracy of the number of loops and the pitch. The lap length of the circumferential reinforcement at both ends of the reinforcing steel cage should not be less than 300mm and should be welded.

3. Place the pre-straightened and cut longitudinal reinforcement bars in the design sequence, welding the ends to the circumferential reinforcement. Note that the distance between the edge circumferential reinforcement at both ends and the end of the longitudinal reinforcement should not exceed 10mm.

4. When using manual arc welding to reinforce the reinforcing steel cage, the longitudinal and circumferential reinforcement bars should be pre-pressed together. Use a thinner welding rod and adjust the arc welding machine to a lower welding current. While ensuring welding quality, try to avoid severe ablation of the reinforcement bars. If necessary, take samples from the welded area to test its tensile strength, ensuring it is not lower than that of the base material.

5. Reinforcement points are concentrated at both ends of the reinforcing steel cage and at locations with interlayer stirrups.

6. Precast stirrups are used to support the double layers of reinforcing steel. The stirrups are positioned on the longitudinal bars at both ends of the cage, with 3-5 stirrups placed every other longitudinal bar.

When the extrusion-type cement pipe-making machine uses manual tying to form the reinforcing steel cage, the longitudinal bars must be made of cold-rolled ribbed steel bars, and the tongue and groove ends must be reinforced with manual arc welding to prevent the circumferential reinforcing bars from shifting due to the impact of falling concrete.
