The concrete pile mould is one of important pile production equipment, it is not only a forming mold but also is a device to bear tensioning force. Pile mould is easy to be broken and deformed because the mould needs bearing centrifugal force, vibration force, heat force, fatigue stress during the production, so when designing the mould, the mould need to be with enough strength and rigidity except for precise size, simple structure, convenient for disassembly and assembly.


1. The cylinder of pile moulds is made to order according to different piles, the longest cylinder is 6m with less welding seam and reduce influence of welding distortion and error of manual joining, the material is Q235B or Q345B. 2. The material of mould wheels is hammer or cast steel, wheels are made by automatic Panasonic welding robot, high welding strength and less welding stress. 3. Our moulds adopt intermittent welding technology, welding method is CO2 gas shield welding, we also use Panasonic welding machine and mixture gas to weld moulds, a solid solder joint appearance, there is no brittle fracture caused by manual welding, oxidation, solder false. 4. Our company has introduced 18m heavy duty lathe, the mould below 12m adopts whole lathe machining to improve concentricity of moulds. 5. Our customers can choose different types of steel plates and flanges. 6. The processing equipment of join plate is from the previous planer processing technology to the milling machine processing technology, improved production efficiency, saving labor costs.

The working principle of concrete pile spinning machine is transmitting the power of the motor to the driving wheels by the belt transmission, drive the rotation of the steel mould by the friction between the driving wheel and the running wheel of steel mould, so as to achieve the purpose of centrifugal shaping of concrete. Our spinning machine has advantages like firm structure, safe and energy-saving.


Concrete pile steel cage welding machine is divided to General type and Automatic type. General type is controlled by traditional speed regulator with easy maintenance which is mostly used in old concrete pile plants; automatic type is frequency variable controlling decreasing the depending on the experienced staff which is easy to be operated by learners. Automatic end encryption pitch, adjusting length with digital calibration which guarantees the quality of concrete pile steel cage.

The automatic clamp for steel mold adopts compressed air to push the cylinder. The closed self-locking performance of fixture is good, safe and reliable; Multi-purpose machine meets the requirements of automatic clamping and releasing of pile dies and steel cages for various processes in the pile production line.
The design principle for automatic clamp for steel mould:
1. Hanging beam: Need to consider the inhomogeneity of force due to the deformation of the pile mold, even sometimes only 3 force happen when there are four force points, the hanging beam design must reach enough rigidity. At the same time, since the hoisting speed of the crane generally reaches 13m/min, the dynamic load factor is relatively large.
