A kind of stretching mechanism with buffer protection structure for spring production

Abstract

The invention discloses a stretching mechanism with a buffer protection structure for spring production, relates to the technical field of spring production, specifically a base and a box body, a support is fixed above the base, and a connecting turntable is installed on the front of the support , the front of the connecting turntable is connected with a backboard, the upper and lower sides of the box are provided with chutes, and the box is located on the front of the backplane, the inner side of the chute is equipped with a translation door, and the side of the translation door There is a transparent toughened glass window in the middle, a handle is installed on the front of the translation door, and a fixed frame is installed on the inside of the box. The spring production uses a stretching mechanism with a buffer protection structure, which can perform a tensile test on the spring. The main test structure of the device is installed in the box, and the back plate on the back of the box can be rotated on the support by connecting the turntable to adjust the inclination angle of the box. The spring placed vertically in the box also tilts with the box. It is convenient to carry out tensile tests on springs under different inclination angles.

Description

technical field [0001] The invention relates to the technical field of spring production, in particular to a stretching mechanism with a buffer protection structure for spring production. Background technique [0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under the action of an external force, and returns to its original shape after the external force is removed. Since the spring generally gathers a large amount of energy when it is working, when the mass of the spring is less than When the spring is closed or exceeds the working limit of the spring, the spring is prone to cracking, deformation and damage in an instant, which is more dangerous. Therefore, after the spring is produced, it is generally necessary to perform a tensile or compression test to test the structural strength and working performance of the spring. [0003] The general spring tension detection mechanism is an open structure. During the spring...

Problems solved by technology

[0003] The general spring tension detection mechanism is an open structure. During the spring tension test, the spring is easy to break to the outside of the device, hurting the user, and the safety is low, and the ordinary spring tension detection device is generally a vertical structure. , only the vertical spring test can be performed, the detection range is small, and the flexibility of use is low. At the same time, the spring tension detection device does not have a buffer structure. When the spring test breaks, it is easy to cause damage to the device.

[0004] A kind of spring member repeated stretching device disclosed in Chinese invention patent application publication specification CN106197991A, although this stretching device is provided with the fixed plate and the load plate that are used to fix the two ends of the spring, it can test several springs at the same time, thereby testing The result is more accurate. However, the stretching device needs to place a certain weight of weight in the load slot on the load plate for detection, which has the disadvantages of low numerical accuracy, too simple structure and inconvenient adjustment.
