Description

Technical Field

[0001] This utility model relates to the field of core mold processing, and in particular to a socket positioning processing device. Background Technology

[0002] In recent years, the scale of cities in my country has expanded rapidly, and urban water supply and drainage projects have become an important part of urban infrastructure.

[0003] A significant feature of the core mold vibration process is its versatility; a single mold can produce cores with different interface types, such as flat-mouth, flexible tongue and groove, and FB jacking pipes. All of these use a working method where the socket is at the bottom and the spigot is at the top. After the material is laid out, the rotating gantry of the core mold host moves from a non-working position to a working position and locks itself before forming the spigot end. The working surface size of the concrete core spigot is achieved by using one hydraulic cylinder and two rubbing cylinders. After forming, the spigot body is detached from the formed core by a lifting cylinder, allowing for immediate demolding.

[0004] However, with urban development and the widespread application of FA-type jacking pipe cores, the A-type, due to its concave spigot body, cannot be formed by rolling and molding like the B-type. As a result, for a long time, the core mold process adopted a wait-and-see attitude towards this type of interface core. Small-sized A-type jacking pipes use the suspension roller process, while large-diameter ones use vertical vibration production. Both of these processes require a large number of molds and steam curing to achieve mass production, which increases the user's finished product quality and reduces user efficiency, making them unsuitable for the needs of a rapidly developing era.

[0005] Therefore, the applicant filed a utility model patent application in 2021 with application number CN202120466456.2, entitled "Steel Socket Type A Pipe Forming Mold". This invention provides a mechanical improvement for producing FA jacking pipe cores using a core mold process. It changes the conventional mold production method, achieving a new production method with the spigot at the bottom and the socket at the top, ensuring the smooth forming of FA jacking pipe cores, which has been well received by customers.

[0006] However, as its use became more widespread, we discovered new problems. The production method of placing the steel socket and spigot at the bottom ensured the spigot's forming, but it could not guarantee the size and position of the steel ring in the socket, thus reducing reliability.

[0007] Currently, such as Figure 3 As shown, the market adopts a method of making a simulation template 10. First, the steel cage 8 and the socket steel ring 3 are fixed in position on the template 10 and then welded. Then, the core is put into the mold to produce the tube. Since different specifications of molds require different specifications of simulation templates, it not only increases the labor intensity of workers, but also increases costs and reduces production efficiency.
