A leaf spring hydraulic quenching forming device

Abstract

The invention provides a hydraulic forming and quenching device for plate springs, and the hydraulic forming and quenching device comprises a support pillar, a disc, an annular oil groove, a center valve, a forming fixture, a supporting roller, a driving and braking hydraulic oil cylinder, a plunger pump motor set, and a PLC (programmable logic controller)-based control system, wherein the forming fixture is provided with a fixture oil cylinder, and the control system comprises an induction plate and a proximity switch. The length of a stokehold rotating conveying chain required by the device disclosed by the invention is just 5 meters, and the forming fixture is annularly arranged, so that the hydraulic forming and quenching device for the plate springs disclosed by the invention is small in land-occupied area and small in application amount of a quenching medium, therefore, the hydraulic forming and quenching device for the plate springs is low in cost for putting into operation and high in production efficiency, the positions of operators are fixed, and the implementation of mechanized operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of leaf spring processing, in particular to a hydraulic quenching and forming device for leaf springs. Background technique [0002] In the heat treatment and forming process of leaf spring, a larger quenching oil tank is often used, about 50 tons of quenching oil. The steel plate to be processed is delivered to six sets of 3-cylinder quenching fixtures through a nearly 60-meter-long transport chain. The operator goes back and forth to the quenching fixture to manually load the material. After forming, the 60-meter-long oil chain plate in the oil tank is used to transport the quenched steel plate. [0003] The existing equipment has a total of 2 conveyor chains, 6 sets of quenching hydraulic systems, and a 50-ton oil tank; 2 transmission conveyor chains, covering a large area of ​​nearly 60 square meters; the cost of primary equipment investment is high; more than 50 tons are required for operation The quen...
