Abstract

The invention discloses a one-step forming device for coil springs. The one-step forming device comprises a coiling mechanism. The coiling mechanism comprises an upper cutting block and a lower cutting block which are fixed onto a fixing plate of a framework, one end of the lower cutting block is mounted on the fixing plate via cylindrical pins, the upper cutting block is mounted on the fixing plate with an elongated slot, the other end of the lower cutting block is connected with a cylinder connecting block by cylindrical pins, the cylinder connecting block is fixedly connected with a cylinder, the cylinder is connected with a cylinder frame by cylindrical pins, the cylinder frame is fixedly connected with the framework, and a lower cutting block adjusting screw is arranged above the lower cutting block. A spring steel band is bent by the aid of the upper cutting block and the lower cutting block so as to be coiled and formed, and the coiling diameter of the spring steel band can be conveniently and precisely adjusted by adjusting the positions of the upper cutting block and the lower cutting block.

Description

technical field [0001] The invention relates to a spring steel strip forming device, in particular, a device for rolling and forming a spring steel strip material used for making coil springs. Background technique [0002] Found through literature retrieval to prior art, existing spring steel strip coiling device is to use three rollers or roller structure mostly, promptly has two rollers or roller on one side of steel strip, and the other side of steel strip There is a roller or roller on one side, and then one roller or roller moves to squeeze the steel strip in the direction of two rollers or rollers, so that the steel strip is bent and deformed, and at the same time, the three rollers or rollers rotate together to complete the coiling of the steel strip forming. Its disadvantage is that it is very troublesome to adjust the coiling diameter of the steel strip, and the diameter of the roller or roller must be changed according to the thickness of the steel strip and the r...
