technical field

The utility model relates to a forming structure, in particular to a spring-type forming structure applied to electrical component pins.

Background technique

With the development of science and technology, the application of electrical components is becoming more and more ubiquitous. The common ones are pin components and patch components. Commonly, patch components will be more widely used in production with a higher degree of automation, but in the relative degree of automation In the lower production process, the application degree of pin components will be higher.

The stitches of pin components are straight when they leave the factory, especially the pins of multi-pin components are often very small. In pcb design, in order to facilitate soldering or routing, the pitch of the pin holes on the pcb will be relatively enlarged. Therefore, before inserting the pin components into the pcb, the pins of the components need to be shaped to fit the pin holes. Processing facilitates the pins of the components to enter the pin holes of the pcb, and maintains a unified and coordinated posture of the components.

Now commonly used component pin forming is very common, single pin is sequentially formed in multiple steps, and a set of equipment can only process one pin pitch of one component, the effect is low, and the scope of application of the equipment is small.

The moving shaft can only slide axially, the push block group can only slide axially along the moving shaft, the moving shaft passes through the push block group, and the push block group can be connected with the moving shaft Relative movement occurs in the axial direction of the moving shaft. The spring group is a compression spring. One end of the spring group is fixed on the push block group and the other end is fixed on the moving shaft. It consists of a shaft and a limit block, and the limit block is fixed on the fixed shaft.

Further, the push block group is composed of push block 1 and push block 2, the spring group is composed of spring 1 and spring 2, the spring 1 is connected to the push block 1, and the spring 2 is connected to the push block Two, the limit block is composed of a limit block one and a limit block two, the limit block is limited to the push block one, and the limit block two is limited to the push block two .

Further, the push block group is composed of push block 1 and push block 2, the spring set is spring 1, the spring 1 connects the push block 1 and the moving shaft, and the push block 2 is connected to the On the moving shaft, the limit block is a limit block one, and the limit block is limited to the push block one.

The beneficial effects of the utility model are as follows:

1. The spring of the utility model cooperates with the push block to form a flexible push block. Only one transmission shaft is required to input thrust to multiple groups of flexible push blocks, and cooperate with multiple limit blocks to realize various working strokes of different distances, and then realize multiple Stitches with different degrees of bending are formed at one time, which improves the forming efficiency and reduces the processing procedures;

2. The power of the push block in the utility model comes from the spring, but the travel displacement of the push block is determined by the corresponding limit block. As long as the compression stroke of the spring is greater than the target stroke of the corresponding push block, the entire push group does not need to be changed, only the limit block needs to be adjusted. The limit block in the bit group can simply adjust the target stroke of the push block, so as to adapt to the different molding requirements of more components with lower cost and high efficiency.
