    Share a combined drain steel moldShare a combined drain steel mold

    At present, the steel mold of the drain pipe for the production of the drain pipe is composed of the outer mold, or the inner mold and the outer mold are connected together. The interface part of the mold is integral with the pipe body part, so it is a mold with an integral structure, and each mold can only produce a drainage pipe with a specification interface form. In the pipeline engineering of the drainage system, the concrete pipe and reinforced concrete pipe used include a tongue and groove pipe with a flexible interface

    There are many knowledge points about the cement inspection well mold, mainly focusing on the use of template thickness, production details and specific uses of several links. In the production of cement inspection wells, most are prefabricated. However, if the project requires on-site casting operations, only the holes at the bottom of the mold can meet the production requirements.

    1. After the inner diameter of the cement pipe mold is clamped, use calipers or steel rulers and a steel tape to measure the inner diameters of both ends of the mold cylinder, the closing direction and the vertical direction. The inner diameter of the same section of the mold is larger than the vertical size. 2-4, and the transition should be smooth. 2. The nominal length is measured with a steel tape measure, and the upper limit deviation of the nominal length of the mold + 4 /-3. 3. The clearance between the end mold and the cylinder

    1 When the cement pipe machine is running, there are regular knocking sounds, and the sound is very loud. Some of the liner bolts are not tightened. During rotation, the liner strikes the mill barrel. Judge the liner part according to the sound, find out the loose bolt and tighten it separately. {{1}}, the temperature of the machine and motor bearings has risen, exceeding the regulations. If you try to touch the bearing by hand or the temperature is too high, check and handle it from the following items. (1) Check the lubricating points of each part, whether the brand of lubricating oil used is the same as the manufacturer's manual.

    How to choose cement pipe mouldHow to choose cement pipe mould

    Due to the expansion of production scale, many customers need to buy more cement pipe molds every day. So how to choose high-quality and low-cost molds from many manufacturers? Qingzhou Sanlong Building Material Equipment Factory will show you how to select molds. The editor believes that customers who produce cement pipes know that there are differences in the appearance and quality of cement pipes produced by certain molds. Some of the cement pipes produced with the mold are smooth and tidy, and some are cracked with the release mold. When the mold is soiled with cement, etc., once the product fails, the production cost will rise. These problems need to be resolved from several aspects:

    1. Before starting the construction of cement culvert equipment, the construction site must be hardened, including the sand and stone material storage site, pipe joint production and storage site, etc. Before starting the construction, the concrete mix ratio and the mechanical properties of the steel bars should be tested. 2. Reinforcing steel production must be carried out in strict accordance with the construction drawings and specifications. Since the construction process of pipe joint forming is centrifugal forming, the steel reinforcement must be spot welded, and the reinforcement thickness of the protective layer should be spot welded outside the steel cage. Only after passing the inspection can the next procedure be entered.

    Cement concrete refers to the general name of engineering composite materials that are mixed by cement, sand, stone and other water. At present, most of the water supply and drainage pipes in most cities in China use cement concrete pipes as culverts. Concrete is the main contemporary civil engineering material. one. It is made of cemented material, aggregate and water in a certain proportion, formed by stirring and vibrating, and cured under certain conditions. Concrete has the characteristics of abundant raw materials, low price and simple production process.

    Cement pipe is a kind of prefabricated pipe made of cement and steel bar using the principle of centrifugal force of electric pole. In recent years, with the frequent occurrence of urban waterlogging, the demand for cement pipelines has continued to increase, and the market prospects are considerable. This has also attracted many companies who want to invest and set up factories. According to the principle of saving investment, talk about which cement pipe equipment is suitable for the initial investment and production of cement pipes? 1. Cement pipe machine Cement pipe making machine is the main machine for producing cement pipes, and it is very important production equipment. According to the production process, it can be divided into vertical extrusion tube making machine, centrifugal tube making machine, suspension roller tube making machine, radial extrusion tube making machine and mandrel vibrating tube making machine.

    The cement pipe mold is a steel mold, and the glass steel mold can also be split or split to facilitate the lifting of the mold. Mould (müJù), a variety of molds and tools used in industrial production, used for injection molding, blow molding, extrusion, die casting or forging, melting, stamping and other methods to obtain the desired product. In short, a mold is a tool for forming objects. This tool is composed of different parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the forming material.

    In highway construction, the quality of the culvert used is high, mainly reflected in the design of the steel bar is double-layer spiral steel bar, and the diameter of the steel bar is large, the main bar diameter is 8 ~ 12 mm, protection Layer thickness {{2}} cm. The inner diameter of the culvert is 8 0 ~ 1 8 0cm, and the length is {{2}} m. The allowable error is: pipe length 0mm, -10mm, inner and outer diameters 10 mm, -10mm, pipe wall thickness 10 mm, -5mm. From the structure, it can be seen that there are two main difficulties in prefabricated culvert: one is to design a qualified cement culvert mold for easy folding; the other is to ensure that the manufactured spiral steel cage meets the design requirements and can accurately drop the mold.
