Custom constant force spiral spring for tobacco shelf pusher

정력 스프링 설계 시 고려해야 할 두 가지 측면

Time:2022-9-15

The constant force spring is made of stainless steel strip. The high strength steel strip is shaped by specific spring production equipment. When the external force is straightened, the hair strip will naturally roll back and produce elastic force. However, to achieve our goal, we can return to the designated starting point after displacement.     Constant force spring has the characteristics of maintaining constant force in a long stroke. Its function can be applied to the adjustment of lifting doors and windows, computer monitors and fans, shopping mall display shelves or motor carbon brush motors and other products that require linear motion such as round trip, sliding, stretching, homing, balance or force saving. So how to design the constant force spring in line with product performance ? We generally need to consider from two aspects :     1. Performance of constant force spring    The two most important properties of the constant force rod are elastic value and life. The thicker the elastic               material, the wider the width, the higher the elastic force. Among the materials with the same size, the smaller the     crimp diameter is, the higher the elasticity is, and vice versa. On the contrary, under the same manufacturing             conditions, the thinner the material is, the better the life is. In the same size of the material, the smaller the coil diameter is, the shorter the life is, and vice versa.     2. Installation space of constant force spring    Generally, the outer diameter of the spring...

Application of variable force spring in electric roller shutter

시간:2022-9-14

The electric roller shutter has many advantages, such as beautiful and simple appearance, firm and durable structure, etc. the roller shutter is suitable for a variety of places, such as business office buildings, hotels, restaurants, offices and homes (used as gauze curtain), especially for large-area glass curtain walls. When the roller shutter fabric is put down, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good sunshade effect. When the roller shutter is raised, its volume is so small that it is not easy to be detected. Have you ever thought about why the roller shutter will automatically rise and fall, and can freeze at any position without running up or down? You may not have an in-depth understanding, because the addition of variable force spring makes the electric roller shutter achieve this effect. The electric roller shutter extends from the longest to the shortest, and the weight of the lower beam changes from light to heavy. Therefore, the elastic force of the variable force spring needs to gradually increase from small to large, reaching the full stroke and gravity balance. So that the curtain can stop and hover at any position. Many variable force springs on the market can not reach the variable force spring whose force is changing at any section, so many electric roller blinds will add some components (deceleration device, damping device, gear device, limit device, etc.) to achieve the effect of perfect lifting, free positioning and free pause. Qianye often contacts with some foreign curtain industries, especially in cordless curtains and roller blinds, which...

The QY spring mechanism of manual cordless blinds is very different from ordinary wire springs

Time:2023-3-6

The QY spring mechanism of manual cordless blinds is very different from ordinary wire springs, and its core component is the need for a spring with negative gradient. Cordless blinds are usually designed to encounter the problem that when the blinds is pulled to the top it will sag and when it is pulled to the bottom it will return to a certain height of the spring. The main purpose of Qianye Precision is to provide a control system for cordless curtains to hover freely, so that the lifting and lowering of the cordless curtains can stop at any position desired by the user. At the same time, there will not be a situation where the internal elastic element is fatigued and cannot be kept fully open.

Add constant force spring in the mechanical arm to make it more stable

시간:2022-9-14

Adjustable mechanical arms are commonly used in offices, laboratories, studios and other locations to support objects at various angles and heights, such as lights, computer screens, laboratory instruments, microphones, etc.   The adjustable manipulator consists of a base member and two connecting rods connected through a pivot joint, which are held in place by friction in the joint. By using spring assisted balancing devices that compensate for most of the weight, the amount of friction required to keep the equipment in place is reduced.   The pivot is a connecting ring that can rotate around an axis set at the pivot point, and a way to attach a spring to the pivot point to reduce the amount of force required. Apply to the arm to place the supported object in the desired position. The auxiliary balance device uses a constant force spring, because the constant force spring provides a smooth range of motion and a constant load in the extension or retraction direction. This can provide smooth motion and force requirements that predict the smallest detail, and the force applied by the constant force spring is more constant over the entire range of motion of the two arms of the device. If coil spring balance is used, a constant force may not be applied to the supported object at all positions of the upper arm part and the lower arm part. For example, at the far end of the range of motion, usually, the force applied to the supported object is insufficient or too large, making it difficult and troublesome to place the...
