Example Embodiment

[0013] The fast hydraulic press system is mainly composed of main engine, lubrication system, hydraulic system, electrical control system and other auxiliary parts, protection system and so on. Wherein, the part other than the mainframe refers to and quotes the prior art, and will not be described in detail here. The main improvement part of the technology of the present invention revolves around the host part, and the following is combined with the attached figure 1 , 2 and the embodiment further illustrate the host part.

[0014] The main engine is a combined frame type tie rod pre-tightening structure, and the fuselage is a split frame structure, which is composed of an upper beam 2, a lower beam 4, a slider 3, a column 1, a tie rod 12, and a lock nut 13. The upper beam 2, the lower beam 4, and the column 1 of the main engine are tensioned by pull rods 12, and are pre-tightened and fixed with lock nuts 13 to form a closed force-bearing frame. The main oil cylinder 6 and ...

Abstract

The invention discloses a rapid hydraulic press system used for hot-stamping forming of a high-strength steel plate. The technical scheme adopted by the invention is as follows: the rapid hydraulic press system comprises a main machine, a lubricating system, a hydraulic system, an electrical control system, auxiliary parts and a protective system. The main machine comprises a stand column, an upper beam, a sliding block, a lower beam, a movable workbench, a main oil cylinder, a sliding block plunger cylinder, a hydraulic cushion piston cylinder, hydraulic cushion plunger cylinders, a displacement monitoring device and a PLC (programmable logic controller) control system, wherein the main oil cylinder is connected with the center of the sliding block, the sliding block plunger cylinder is fixedly connected with four corners of the sliding block, the center of the movable workbench is matched with the hydraulic cushion piston cylinder, the two hydraulic cushion plunger cylinders are symmetrically arranged at two sides, and the displacement monitoring device is installed on the stand column. The rapid hydraulic press system can be used for solving the technical problems existing in the prior art, and realizing both rapid die assembly and pressure maintaining in the stamping process of the steel plate.

Description

technical field [0001] The invention relates to a hydraulic press system for hot stamping, in particular to a rapid hydraulic press system for hot stamping of high-strength steel plates. Background technique [0002] With the continuous development of society and the continuous enhancement of people's awareness of environmental protection, energy saving, environmental protection and safety have become an inevitable trend in the development of the automobile industry. The use of high-strength steel plate hot stamping forming technology is an effective means to reduce the weight of automobiles and improve safety. The core of the hot stamping forming technology is to stretch the high-strength steel plate in the hot state and quench it at the same time, so that the steel plate changes from austenite structure to martensite structure, so as to achieve high tensile strength of the steel plate. This technology requires a press that can close the mold quickly and maintain the corres...
