Description

Technical Field

[0001] The utility model relates to the technical field of cement pipe production, and more specifically, to a forming die for cement pipe production. Background Art

[0002] Cement pipe, also known as concrete working pressure pipe or reinforced concrete pipe, is a prefabricated pipe made of cement and steel bars as the main materials. Its manufacturing process usually includes mixing cement, lime, sand and other materials, putting them into a mold, and making them through processes such as centrifugal, pressing, molding or hanging composite molding.

[0003] The existing forming mold for cement pipe production has certain disadvantages during use. First, during the operation of the existing cement pipe production mold, the pre-mixed cement mortar is usually poured directly into the mold, and then it is waited for to solidify naturally. However, this direct pouring method often inevitably brings in air, especially during the flow of cement mortar, the air is easily entrained into the mold, and then forms air and bubbles in the corners of the mold and between the cement slurry. These bubbles cannot escape during the cement solidification process and will eventually remain inside the cement pipe, resulting in a significant decrease in the density and strength of the cement pipe. The reduction in density and strength means that the bearing capacity and impermeability of the cement pipe will also decrease. For cement pipes that need to withstand external pressure or are exposed to water environments for a long time, this is undoubtedly a huge safety hazard. Once these cement pipes are used in important infrastructure construction, their potential quality problems may threaten the safety and stability of the entire project. Secondly, the existing production method cannot effectively accelerate the hydration reaction in cement. The hydration reaction is a key process in the solidification and hardening of cement, which determines the conversion speed and curing time of the cement pipe from liquid to solid. However, under the existing production mode, the hydration reaction of cement mainly depends on the temperature and humidity under natural conditions, which makes the solidification and hardening process of cement relatively slow. This not only increases the curing time of cement pipes and reduces production efficiency, but also may cause internal stress in cement pipes due to temperature changes during the curing process, further affecting the quality and stability of cement pipes. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a forming die for cement pipe production, which has the advantage of good cement pipe production forming effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a forming mold for cement pipe production, comprising a workbench and a forming mold, a hollow column movably installed on the top of the workbench, two hollow columns are distributed on both sides of the forming mold, a sleeve is fixedly installed inside the hollow column and the sleeve extends to both ends, a push rod is movably installed inside the sleeve, a back plate is fixedly installed at one end of the push rod, a hinge block is fixedly installed at the bottom of the other end of the push rod, a support plate is fixedly installed on the side of the hollow column, a motor 1 is arranged on the top of the support plate, a disc is fixedly installed on the output shaft of the motor 1, a fixed shaft is fixedly installed on one side of the disc, and an articulated rod is hingedly connected between the fixed shaft and the articulated block.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model uses the power of a motor to rotate the fixed axis on the surface of the disc. Due to the hinge of the hinged rod, the disc drives the hinge block to move back and forth while rotating, and the push rod moves back and forth inside the sleeve, and continuously strikes the forming mold through the abutment plate. Compared with the traditional device, this device can make the concrete inside the cement pipe more compact and reduce gaps and bubbles by knocking, thereby improving the density and overall strength of the cement pipe, which helps to improve the bearing capacity and impermeability of the cement pipe, and at the same time can accelerate the hydration reaction in the cement, so that the cement condenses and hardens faster, which helps to shorten the curing time of the cement pipe and improve production efficiency. In addition, by knocking, the steel bars inside the cement pipe can be better combined with the concrete to form a more stable structure, which helps to improve the seismic resistance and durability of the cement pipe.

[0013] 2. The utility model uses the power of motor 2 to rotate the bidirectional screw rod, and then the two sets of socket blocks movably installed on the surface of the bidirectional screw rod move relatively, thereby adjusting the distance between the two sets of hollow columns. Compared with the traditional device, this device can adapt to the production needs of cement pipes of different lengths and sizes, so that the same set of equipment can handle more types of cement pipes, improving the adaptability and production efficiency of the production line, and at the same time ensuring that the two sets of abutment plates have more uniform striking force and frequency on both ends of the cement pipe, thereby helping to ensure the overall quality and consistency of the cement pipe and reduce quality problems caused by uneven striking.
