Abstract
The utility model discloses a hydraulic driving control loop for upper and lower rollers of forging and pressing equipment. The hydraulic driving control loop comprises two sets of motor driving loops which are singly supplied with oil, wherein each set of motor driving loops is connected with an oil pump, a check valve and a reversing valve in turn through an oil pipe; a hydraulic control check valve for respectively controlling the two sets of motor driving loops is connected between the two sets of motor driving loops; and the hydraulic control check valve is connected with a solenoid directional valve. The problems of the prior art are solved by the hydraulic driving control loop provided by the utility model; the upper and lower rollers of the forging and pressing equipment are hydraulically gang controlled to work; the control is flexible and the operation is simple; and the hydraulic driving control loop is suitable for wide application in related industries.
Description
Technical field
The up-down rollers hydraulic-driven control loop in the utility model metal forming machinery field, particularly forging equipment.
Background technology
Forging equipment is an imperative equipment in the commercial production, and the type of drive of original four-roll plate bending machine is a Mechanical Driven, and the Mechanical Driven control method is single, and accuracy is not high.
The utility model content
The purpose of utility model: for addressing the above problem, the utility model provides a kind of control up-down rollers hydraulic-driven control loop of forging equipment flexibly.
Technical scheme: for achieving the above object, the utility model is taked following technical scheme:
A kind of up-down rollers hydraulic-driven control loop of forging equipment; The motor driving loop that comprises two groups of independent fuel feeding; All be connected with oil pump, check valve and reversal valve in turn through oil pipe on said every group of motor driving loop; Be connected with the hydraulic control one-way valve of controlling two groups of loops respectively between two groups of motor driving loop, said hydraulic control one-way valve all is connected with solenoid directional control valve.
Through the utility model, that has realized four-roll plate bending machine up-down rollers fluid motor-driven can and can divide the control pattern, when up-down rollers to drive simultaneously; Hydraulic control one-way valve is opened in the work of hydraulic control one-way valve control loop, and two oil pumps merge fuel feeding; Two roller rotating speeds adapt to automatically, drive as only needing top roll, the reversal valve Yv3 or the Yv4 work that can let the control top roll drive; Control Yv7 electricity condition, can let an independent fuel feeding of oil pump, also can let two oil pumps fuel feeding simultaneously.Change the electric combination that gets of electromagnet, can realize multiple duty, conveniently satisfy the needs of various roll bending technologies.
Beneficial effect: through using the up-down rollers work of the utility model through fluid pressure linkage control forging equipment, control flexibly, and is simple to operate, is fit to being widely used of relevant industries.
Description of drawings
