Problems solved by technology
Existing rectangular spring forming equipment using rectangular steel wire as raw material usually uses extrusion blocks to fix the steel wire raw material on the forming roller during the forming and preparation of the rectangular spring. In this way, when the forming roller rotates, extrusion The relative sliding friction between the block and the steel wire material will affect the winding shape of the rectangular spring; at the same time, the fixed force on the initial winding end of the rectangular spring is not uniform. springback deformation

The invention discloses a rectangular spring forming equipment, which relates to the technical field of rectangular spring production equipment, comprising a frame body, a drive motor is installed on one side of the frame body, and a drive shaft is fixedly connected to the output end of the drive motor. The driving shaft is coaxially fixedly connected with a forming roller, the forming roller is rotatably connected in the frame body, and a spiral forming groove is opened on the outer peripheral side, and a pressing mechanism is arranged in the frame body, and the pressing mechanism includes a pressing wheel, The spiral pressure groove, the tension wheel and the transmission toothed belt, the present invention adjusts the contact pressure between the spiral pressure groove on the pressure wheel and the steel wire in the spiral forming groove on the forming roller by rotating the adjusting bolt, and drives it through the driving motor and the transmission toothed belt The pressing wheel and forming roller rotate in opposite directions synchronously, and the spiral pressing groove keeps squeezing the rectangular spring winding working end in the whole process of the spiral forming groove, which greatly improves the traction force of the steel wire raw material winding and ensures the processing quality of the rectangular spring.
Description
technical field [0001] The invention relates to the technical field of rectangular spring production equipment, in particular to a rectangular spring forming equipment. Background technique [0002] Rectangular spring material has a rectangular cross-section, which is very suitable for occasions with high load and very limited space, and meets the needs of high-speed compression and super-heavy load. Existing rectangular spring forming equipment using rectangular steel wire as raw material usually uses extrusion blocks to fix the steel wire raw material on the forming roller during the forming and preparation of the rectangular spring. In this way, when the forming roller rotates, extrusion The relative sliding friction between the block and the steel wire material will affect the winding shape of the rectangular spring; at the same time, the fixed force on the initial winding end of the rectangular spring is not uniform. Rebound deformation occurs after processing. Conte...
