Current：
At present, our products and services have been deployed in the automotive industry, rail transportation, new energy and other fields . Through technological innovation, we realize three core values: improving connection reliability and reducing the risk of loosening in extreme environments; improving assembly efficiency and reducing manual intervention and repetitive work; and enhancing operational safety and avoiding process hazards in traditional assembly. We strive to bring revolutionary breakthroughs to the global fastening industry.
The core of bolt connection quality depends on the preload , and the key to ensuring the uniformity of the bolt connection system quality lies in achieving uniform control of the preload of each bolt. Currently, the mainstream bolt assembly methods can be divided into three categories, and their technical characteristics are compared as follows:
Installation Method | Control methods | Core Content | Dispersibility |
Tightening method | Torque control | Calculate the installation torque required for a specific preload | high |
Corner control | Specify the twist angle and monitor the torque simultaneously | middle | |
Torque-angle control | Coordinated control of torque and angle to achieve assembly | Medium-low | |
Yield point control | By detecting the change in the slope of the torque-angle curve | Lower | |
Preload control | Real-time monitoring of preload change value | Low | |
Stretching method | Axial force control | Directly stretch the bolts through the tensioning device | Low |
Heating method | Temperature control | Heat the bolt to the specified temperature through the heating device | middle |
The following problems are common in the current industry:
1. Insufficient preload control accuracy: Due to fluctuations in the friction coefficient, the traditional torque assembly method results in a dispersion of actual preload of more than ±30%, resulting in poor connection consistency.
2. Lack of process data support: The assembly process lacks real-time and accurate data records, making it impossible to trace problems, and quality control relies on post-process testing.
3. The connection status is not visible: the changes in the preload of the bolts during service cannot be monitored, and the risk of potential loosening or fatigue fracture is difficult to be warned in advance.
In response to market pain points, Horycon has developed and launched an integrated solution of "smart tools + data system". With "precise control of preload" as the core, it achieves a "dimensionality reduction attack" on traditional torque control tools and provides a reliable solution for industrial-grade high-precision fastening needs.
1) Ultrasonic Axial Force Wrench
①Manual Ultrasonic Axial Force ②Wrench Electric Ultrasonic Axial Force Wrench ③Hydraulic Ultrasonic Axial Force Wrench
Core advantages:
1. Three-parameter fusion control : real-time synchronous acquisition and control of the three core parameters of preload, torque, and angle , to achieve multi-dimensional precision assurance and eliminate the limitations of single parameter control;
2. Flexible selection of multiple measuring ranges : A variety of specifications and ranges are available to cover bolt assembly requirements from small and medium-sized to large and heavy-duty specifications, adapting to different industry scenarios;
3. Ultra-high control accuracy : The control accuracy of the preload mode reaches ±5%, fundamentally eliminating the error caused by the torque installation method ;
4. Intelligent temperature compensation : built-in high-precision temperature sensor can automatically identify ambient temperature changes, compensate for the impact of temperature on the mechanical properties of the bolt in real time, and ensure accuracy and stability under different working conditions;
5. Digital intelligent management : supports wireless transmission of installation result data and is equipped with dedicated visualization software to realize functions such as real-time data viewing, historical record tracing, and report generation, facilitating intelligent production management;
Note*: This tool must be used with a "patch-type smart fastener” (a piezoelectric ceramic sensor is bonded to the bolt end face , as shown below). The sensor and the wrench work together to achieve direct control of the preload.
1) Electromagnetic ultrasonic axial force wrench
Core advantages:
The core breakthrough of the electromagnetic ultrasonic axial force wrench lies in:
• No need to modify fasteners :It does not require grinding the bolt end face, applying a coupling agent, or attaching sensors; it can be directly adapted to common standard fasteners on the market;
• More convenient operation : simplify the preliminary preparation process, shorten the assembly cycle, and reduce equipment maintenance costs;
• Wider compatibility : It can quickly switch to different specifications and types of bolt assembly scenarios, with greater adaptability.
