Advantages of the Second-Generation SDX Series Crimping Machine (Pipe Locking Machine)

The SDX-90Z (dual-speed single-bevel model) is a crimping machine that incorporates composite cylinder technology with independently owned intellectual property rights. This technology overcomes the drawbacks of conventional crimping machines that rely on multiple auxiliary small cylinders—namely, complex structural designs, inability to achieve independent operation of various systems due to numerous oil lines, short service life of sealing rings, and frequent oil leaks. Thanks to the composite cylinder technology, the crimping head, hydraulic system, and electrical control box—the three major systems—can operate independently from one another. Moreover, this design facilitates easy separation of each system for return to the factory, where they can enjoy long-term warranties.

Its characteristics:

(1) During the crimping process, the mold base drives the crimping die to perform only radial movement, with no axial movement. This allows for precise control of the crimping position when crimping hose assemblies. Once installed, the positioning device works in conjunction with both automatic and semi-automatic operating modes, making it particularly suitable for large-scale crimping operations.

(2) The die pressing seat—also known as the die seat—employs a guided sliding structure in its operation. This design compensates for the uneven spacing of the dies caused by fatigue deformation of the support springs within the die seat over prolonged use, thereby eliminating the need for frequent replacement or adjustment of the springs.

(3) Since the mold base is equipped with two inclined surfaces of different slopes, during the mold’s opening and closing operation, it achieves two distinct speeds—fast and slow. This not only increases the clamping force during the pressing process but also enhances the pressing speed and expands the mold’s opening and closing stroke.

(4) The mold installation adopts a T-slot structure, and the mold positioning has been upgraded to a long-life spring-loaded ball mechanism. This not only ensures reliable operation but also allows the operator to first insert the hose assembly connector to be crimped into the mold before proceeding with the crimping process, thereby meeting the requirements for crimping ultra-large-sized, specially-shaped elbows and non-standard connectors.

(5) In terms of clamping dimension control, the principle of displacement control is utilized, and a graduated adjuster is employed to precisely regulate the clamping dimensions. This allows the clamping dimensions to be directly correlated with the scale readings indicated by the graduated adjuster, achieving an accuracy of 0.01 mm.

(6) The SDX-90Z crimping machine incorporates imported insert-type hydraulically controlled check valves and relief valves in its hydraulic system, and it also increases the pump flow rate and motor power. As a result, the crimping speed of the machine has been significantly improved. The electrical control section is equipped with automatic or semi-automatic crimping functions, fully meeting the extensive needs of the automotive parts and hydraulic industries.
