SDX-150 Crimping Machine

The SDX-150 (dual-speed single-bevel model) crimping machine is a member of the SDX series, featuring a brand-new, unique composite cylinder technology with independent intellectual property rights, and perfectly integrates current international trends.
　　This model is a large-caliber, ultra-large-opening, and ultra-wide-application crimping machine meticulously designed through our company’s extensive and long-term production experience, coupled with comprehensive feedback on quality information gathered from a wide range of users. It features a mold base with a significantly enhanced two-speed ratio—fast and slow—throughout the entire 50-millimeter expansion and contraction cycle. This design increases the duration of the slow-speed phase during the entire contraction stroke, thereby expanding the effective force-bearing segment (i.e., the crimping segment) and enabling a broader range of crimping size control. Moreover, the mold base adopts a basin-shaped contact with the front cover, resulting in minimal frictional resistance. This makes it a powerful and highly efficient crimping machine. Throughout the entire manufacturing process, we have not only employed digital machining technologies but also utilized high-quality alloy steel materials combined with a unique heat treatment process, pushing beyond the conventional limits of wear resistance and load-bearing capacity typically achieved by domestically produced alloy steels after heat treatment. Only by meeting these comprehensive conditions and achieving breakthroughs in heat treatment technology can we design and manufacture this first-class series of crimping machines that simultaneously enhance crimping force and ensure extended service life.
　　Features of this model: (1) The mold remains stationary front and back, employing planar extrusion. As a result, after crimping, it is less likely to develop taper—commonly referred to as "large end, small end." (2) The mold base operates via a guided sliding mechanism that compensates for the deformation of the support springs caused by long-term fatigue, thereby eliminating the need for frequent readjustment due to uneven spacing between adjacent crimping dies. Consequently, after crimping, the lines remain uniform and do not become elliptical. (3) Since the mold base’s linked crimping dies undergo only radial expansion and contraction without axial movement, it becomes easier to precisely control the crimping position during product crimping. (4) In terms of crimping dimension control, the displacement control principle is employed, with an imported scale-adjusting dial used to precisely set the crimping dimensions. This allows the scale values indicated on the dial to correspond directly to the actual crimping dimensions, achieving an accuracy of up to 0.01 mm. The crimping control section is equipped with a selectable manual or automatic operating mode. (5) The main unit and body adopt a split design, with a lower center height for the locking mechanism, making it particularly suitable for on-site mobile crimping operations—ideal for crimping special products such as automotive shock-absorbing airbags, large-flange components, and large-diameter oil pipelines. (6) Mold changes are convenient and quick.

Performance features of the intelligent crimping machine: 1. Multiple processing modes available, including manual, automatic, and custom crimping methods. 2. Three intelligent crimping modes (simultaneous control of size, pressure, and force). 3. Real-time monitoring and uploading of processing data, facilitating subsequent management and traceability of tubing quality. 4. Intelligent setting for compensating crimping rebound. 5. Remote control of the crimping equipment. 6. Smart digital caliper connection for automatic calculation of compensation to correct processing errors. 7. Automatic detection of whether the connector is fully crimped. 8. Intelligent data recognition to prevent erroneous input. 9. No need to manually enter accompanying crimping parameters. 10. Self-diagnosing fault alerts and alarms.

All-Chinese human-computer interaction interface:

Lower the operational threshold, reduce operational errors, and get started with simple training.

Cloud Clamping Process Data:

Cloud-based management of process data, automatically synchronized in real time to all directly operated processing locations.

Visual Quality Monitoring of Displacement/Pressure Curves:

It replaces Finbo’s original ICC4 graphic quality control and Youli IPC pressure curve detection. It can detect differences between pipe fittings from different batches and immediately halt processing while issuing an alert.

The processing compensation system collects in real time the pressure and displacement generated during the pressing machine’s machining process, enabling continuous monitoring and detection of each machining step. It can also immediately correct any operations where the machining dimensions fall short, thereby reducing the error rate in machining.

Processing monitoring is performed every 50 milliseconds, during which the pressure and displacement generated by the crimping process are collected and analyzed. If either the maximum or minimum crimping range is exceeded, the equipment will immediately sound an alarm, alerting the user that there may be a problem with this particular processing operation.

Smart Traceability:

The QR code tracks the compression molding process, processing parameters, production batch, and other relevant information, complying with the standards of the smart industrial component quality traceability system. It also collects statistics on batch numbers, output volume, pass rates, completion times, and production efficiency.

Manufacturing Process Management:

Record over-limit alarms for pressure/displacement, machining parameters, crimping process, and production results.
