Qianye Precision’s design on industrial doors

As the building access door of modern plant, the industrial door must be familiar to everyone. The industrial door has a variety of lifting door modes. It slides upward according to the track installed on the wall, which is fast and stable. At present, the industrial door mainly uses the torsion spring balance system to stabilize the industrial door in the process of operation, so that it can be opened quickly.

  Principle of torsion spring balance system: torsion spring balance is the principle that the weight of the door body is balanced by the torsion torque of the torsion spring. The torsion spring balance system of industrial doors is mainly composed of supporting seat shaft, spring, wire hub, steel wire rope and other components, in which the material of torsion spring is more important. Generally speaking, the torsion spring of the torsion spring balance system needs to be made by computer-aided design and professional equipment.

  Industrial door balance system analysis what are the small problems of torsion spring balance?
  1. In practice, it is difficult to meet the standard requirements due to the influence of spring material and manufacturing process.
  2. When the area and weight of the door are increased, the diameter of the torsion spring and the diameter of the steel wire will be thickened, which will affect the sensitivity of the balance of the torsion spring and increase the difficulty in adjustment.
  3. The installation of torsion spring balance on the door opening with large height width ratio increases the difficulty in designing the torsion spring balance due to the limitation of width. The required torsion spring size is also difficult to manufacture, which greatly increases the cost.
  4. In large industrial doors, several torsional spring groups or transmission shafts are usually used, which will increase friction and reduce balance effect.
  5. After a long time of work, the torsion spring balance will produce a certain degree of fatigue force loss, which will make the original balance state with the door body unbalanced, and increase the working load of the motor.
  As a professional spring manufacturer, Qianye precision will replace the torsion spring with the constant force spring.

  The constant force spring produced by our self-developed spring coiler can achieve extremely high elastic output in a very small device space.

  Moreover, Qianye also strengthened from two aspects, so that the constant force spring can give better play to its elastic effect under the condition of the same size, and it is not easy to loosen the ring. When using materials for constant force spring, we will select suitable spring materials through product design to produce and process spring materials.

  In production, we will also carry out deep processing technology: the clockwork with the same surface size has different processes. In the process of using the constant force spring, the service life of the spring will be too short. The constant force spring produced by Qianye has greatly improved the service life of the spring. Each spring has a certain life cycle. Like the spring force, they are all related to materials and processing technology. If ordinary materials and immature production technology are selected, the service life of products will be greatly reduced.

Shenzhen Qianye Precision Metal Co., Ltd. was established in 2006 to supply high-quality stainless steel springs for many fields. The company designs and manufactures a wide range of power springs, constant force springs, constant torsion springs, variable force springs and motor brush spring. Qianye works in close partnership with its customers in developing bespoke solutions to meet their individual needs.Quality is of the utmost importance and Qianye are certified to ISO9001, ISO14001 and national high-tech enterprise with a big emphasis on the training of its employees. Its spirit is “treat people with sincerity and create things with sincerity” to ensure it strives for excellence.

A power spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after the external force is removed. Also known as "winding spring". The production process of the clockwork spring manufacturer can be completed at one time from simple procedures to complex procedures, and...
