SDX-90Z Crimping 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-line connections, 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 features are as follows: (1) During the crimping process, the die holder drives the crimping die to perform only radial movement without axial movement, enabling precise control over the crimping position. When the hose assembly is fitted, 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—the die holder—adopts a guided sliding structure, which compensates for the uneven spacing of the dies caused by fatigue deformation of the support springs over prolonged use, thus eliminating the need for frequent replacement or adjustment of the springs. (3) Since the die holder is equipped with two inclined surfaces of different slopes, it achieves two distinct speeds during its expansion and contraction movements. This not only increases the crimping force but also enhances the crimping speed and extends the travel range of the die holder. (4) The die installation utilizes a T-slot structure, and the die positioning now employs long-life spring-loaded ball bearings. This not only ensures reliable operation but also allows the operator to first insert the hose assembly connector into the die before proceeding with the crimping process, thereby meeting the requirements for crimping ultra-large, specially shaped bends and non-standard connectors. (5) In terms of crimping dimension control, the machine employs the principle of displacement control, using a scale-adjuster to precisely regulate the crimping dimensions. The scale values indicated by the adjuster correspond directly to the actual crimping dimensions, achieving an accuracy of up to 0.02 mm. (6) The SDX-90Z crimping machine incorporates imported insert-type hydraulic check valves and relief valves in its hydraulic system, and the pump flow rate and motor power have been increased. As a result, the crimping speed of the machine has been significantly boosted. The electrical control section features both automatic and semi-automatic crimping functions, fully satisfying the extensive needs of the automotive parts and hydraulic industries.
