SDX-155 Split-Type Crimping Machine

　　The SDX-155 (dual-speed single-bevel model) crimping machine is a new, unique model in the SDX series that incorporates cutting-edge composite cylinder technology with independent intellectual property rights, perfectly aligning with 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 the careful consideration of quality feedback received from a broad spectrum of users. It features a mold base that boasts an exceptionally wide speed ratio—allowing for both fast and slow speeds—during the entire 50-millimeter expansion and contraction cycle. This design significantly extends the slow-speed segment of the entire contraction stroke, thereby increasing the effective force-bearing section (i.e., the crimping section) 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 advanced 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 exceptional service life.
　　Features of this model: (1) The mold remains stationary front to 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 take on an elliptical shape. (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 regulate the crimping dimensions. This allows the scale values indicated by the dial to correspond exactly 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 this model 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 straightforward.

Smart Crimping Machine Performance Features: 1. Multiple processing modes available: manual, automatic, and custom crimping modes. 2.

Real-time monitoring and uploading of processing data for convenient subsequent management and traceability of tubing quality. 4. Intelligent setting for crimping rebound compensation. 5. Remote control of the crimping equipment. 6. Smart digital caliper connection for automatic calculation of compensation to account for machining errors. 7. Automatic detection of whether the connector is fully crimped. 8. Intelligent data recognition to prevent incorrect input. 9. No need to manually enter matching crimping parameters. 10. Self-diagnosing equipment with fault 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 die-casting process data, automatically synchronized in real time to all company-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 during crimping are collected and detected. 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 numbers, and other relevant data, 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.
