Spring center reinforcing forming device

Abstract

The invention relates to the technical field of spring manufacturing, in particular to a spring center reinforcing forming device. A stamping platform is fixedly connected to the outer surface of a supporting frame, pressure cylinders are fixedly connected to the two sides of the outer surface of the stamping platform, and piston plates are slidably connected to the interiors of the pressure cylinders; a first push rod is fixedly connected to one end of each piston plate, a second push rod is fixedly connected to one end of each first push rod, a third push rod is fixedly connected to one end of each second push rod, and extrusion plates are fixedly connected to the positions, located at one ends of the third push rods, of the outer surface of the stamping platform; and the third push rods drive rack plates to slide on the outer surface of limiting plates only in one direction, and the rack plates cannot move in the opposite direction, so that the phenomenon that the extrusion plates do not clamp a steel plate any more along with reduction of the temperature of the steel plate is prevented, stamping deformation of the steel plate in the early stage is avoided, and meanwhile workers are protected against injuries when working in the high-temperature environment.

Description

technical field [0001] The invention relates to the technical field of spring manufacturing, in particular to a spring center reinforcement forming device. Background technique [0002] Springs are generally made of steel. The types of springs are complex and diverse. The installation shapes mainly include coil springs, arc springs, scroll springs, leaf springs and special-shaped springs. Leaf springs are made of multiple pieces of steel with different lengths and the same width. The sheets are superimposed, and each sheet of steel is superimposed into an inverted triangle leaf spring shape. The uppermost steel plate is the longest, and the lowermost steel plate is the shortest. The number of steel plates is related to the weight of the supporting bus. The greater the rigidity. [0003] Leaf springs are generally stamped and shaped by hydraulic presses, but during the stamping process, they are usually clamped and positioned by manual control of mechanical arms or limit cla...

AI Technical Summary

Problems solved by technology

[0003] Leaf springs are generally stamped and shaped by hydraulic presses, but during the stamping process, they are usually clamped and positioned by manual control of mechanical arms or limit clamps, so that the position of the steel plate is relatively close, and the steel plate with a high temperature of about 700 degrees Celsius is placed on the stamping platform. Second, before stamping, some impurities or small objects may fall on the outer surface of the high-temperature steel plate and burn to ashes. If these ashes are not cleaned up, they will be tight after continuous stamping. Therefore, those skilled in the art provide a spring center strengthening forming device to solve the problems raised in the above-mentioned background technology
