The Perfect Embodiment of Craftsman Spirit: Yajie X Series High Security Lock Core Products

Recently, the German Craftsman's Spirit has been a hot topic in Chinese manufacturing industry. In fact, the Chinese people have never lacked the craftsman spirit since ancient times, but some enterprises and practitioners are unwilling to abandon the short-sighted behavior of impetuosity and pursuing immediate interests, and lack the perseverance of excellence in their products. Craftsman spirit refers to the working concept of craftsmen who are full of emotion for their products, and who are meticulous in carving and excellence in their products. Craftsmen like to constantly improve the product itself and the production process of the product to strive for perfection.

Yajie X series high security anti-theft lock core, which lasted three years of development and continuous improvement. From the beginning of the design, the project team positioned accurately and strived for perfection. Whether it is structural design or process production, they dared to challenge the technical difficulties of the industry and their own perseverance. After hundreds of discussions and improvements, they created the peak work that amazed foreign counterparts. The following is an analysis of the spirit of craftsmen embodied in X series from eight aspects.

Craftsman Spirit 1 (Structural Design): 113 mechanical parts were designed and installed in a 28-cubic-centimeter product space (slightly larger than a 2-yuan-1 lighter) in order to solve the technical opening and maximize the improvement of key performance indicators (key volume).

Craftsman Spirit 2 (Processing Accuracy): For the sake of product performance consideration, the internal structural parts (such as chucks and other key parts) of the product are abandoned, and the manganese steel is usually used in the industry. Stainless steel 304 is selected to overcome the difficult production methods such as stamping die technology, deformation processing technology and batch front processing technology. The deviation of the parts does not exceed +/-0.02mm.

Craftsman Spirit 3 (Unique Groove): In order to ensure that the key can not be copied uncontrollably, so as to maximize the safety of customers, Yajie X Series specially designed a unique key groove, in order to meet its own strength, effectively prevent illegal elements from using screw batches and other violent rotation to open. Although the processing of key groove and locus groove on the key is doubly more difficult, through the development of special machines such as precise numerical control equipment, high-precision technology finally achieves the design effect.

Yajie X Series Unique Key Slot Type

Craftsman Spirit 4 (Device Installation): Compared with other blade locks and marble locks, X series adopts multiple rotating blades superimposed assembly, each blade thickness is only 0.7mm, which can effectively solve the technical opening and vibration opening of the one-by-one breaking method. However, overlapping blade assembly needs to solve such difficult problems as cumulative error and coordinated positioning. After dozens of discussions and innovative experiments, Yajie developers have finally effectively solved this industry problem.

Patent Technology for Blade Overlapping and Location of X Series

Craftsman Spirit 5 (Space Track Slot): Plane Track Slot technology is the mainstream of the market at present, but it is easy to be opened by technology and the key is easy to be illegally duplicated. Aiming at this disadvantage, Yajie X series designed space track groove technology. In the production of CNC processing and other aspects, special CNC equipment is developed for batch production. Its accuracy is required within +/0.03mm.

Craftsman Spirit 6 (Shape Processing): Even on the outer surface of the parts, precision processing technology is used to control the accuracy of the shape size within 0.05 mm, to ensure the positioning and clamping accuracy of the follow-up process. The following is a high-precision photograph of the extrusion process before and after comparison. Common products on the market do not use this high-precision process.

Yajie X Series adopts high precision profile processing technology

Craftsman Spirit 7 (Material): Yajie X series keys are made of high-performance brass, not brass, which is widely used in the market. Although the processing difficulty and cost have increased significantly, for the performance of products, X series keys and other key parts under stress are all made of brass, and their mechanical properties are slightly higher than stainless steel materials. These parts are processed by precision profile technology.

Use more high quality material to strive for higher performance

Craftsman Spirit 8 (Key Quantity): In order to maximize the key parameters of the lock core product, "Key Quantity", the Yajie X series installs as many encoders as possible in a limited space, and the whole lock head can be up to 62 stainless steel blade parts. In order to ensure that the technology of three space trajectory slots is not opened by illegal personnel, 48 coded blades are divided into three angles and six directions to move, so that the methods of tool provocation opening and vibration opening are completely invalid. Its key volume also reached a record 100 million, becoming an industry record.

The precision of X series core components is beyond imagination.

After successful development in early 2015, Yajie X series has undergone several rounds of open technology testing for more than a year. It has not been opened up in the open testing activities so far. It proves that the eight craftsmen'spirit has almost perfect technical performance. China's industrial enterprises need more craftsmen' spirit in pursuit of excellence.
