Compact closed type pressurized hydraulic system profile extruding machine

Abstract

The invention relates to a compact closed type pressurized hydraulic system profile extruding machine. The compact closed type pressurized hydraulic system profile extruding machine comprises a fixedbase, an extrusion part, an oil supply part and a main electric cabinet, wherein the extrusion part, the oil supply part and the main electric cabinet are arranged on the fixed base, the oil supply part comprises a pressurized oil cylinder, an oil way plate, a cooling mechanism, a motor pump set, a hydraulic loop and a liquid filling valve, the pressurized oil cylinder is composed of an oil storage cylinder barrel and a pressurization cylinder, the oil way plate is a control assembly of all the oil cylinders of the extruding machine, the cooling mechanism is used for cooling hydraulic oil, themotor pump set is used for generating high-pressure system pressure of the hydraulic oil when the extruding machine works, the hydraulic loop comprises a pump oil suction pipe, an oil delivery pipe I, an oil delivery pipe II, a working oil pipe I, a working oil pipe II and an oil return pipe, and the liquid filling valve is arranged on the main oil cylinder and communicates with the oil storage cylinder barrel. According to the compact closed type pressurized hydraulic system profile extruding machine, when the extruding machine is used, the use amount of the hydraulic oil is small, the temperature of the hydraulic oil can be effectively controlled during working, the service life of the hydraulic oil is effectively prolonged, and the use cost of equipment is also saved.

Description

technical field [0001] The invention belongs to the field of profile forming equipment and relates to a profile extrusion machine. Background technique [0002] The traditional extrusion machine consists of a fixed base and a mold on the fixed base, the ingot cylinder, the main cylinder, the auxiliary cylinder, the extrusion rod, the oil storage tank, the oil supply pipeline and the main electrical cabinet. The structure of the extrusion machine There are the following technical problems: 1. The oil tank in the hydraulic system is placed above the extrusion machine, and the oil storage capacity is more than 3-4 times the working oil volume, so the hydraulic oil consumption is large and the input cost is high; 2. The traditional extrusion The cooling of the hydraulic oil when the machine is in use requires cooling oil pumps, plate exchangers, cooling water pumps, and cooling towers for heat exchange. This is a secondary heat exchange, so the power consumption is high and the ...

Problems solved by technology

[0003] The purpose of the present invention is to solve the above-mentioned technical problems existing in the existing profile extruder, adopting a closed pressurized hydraulic system, which replaces the large-capacity open oil tank required by the current extruder, and only needs to configure one The oil storage and pressurization cylinder matching the capacity of the working cylinder of the machine is enough. The amount of hydraulic oil used is small when used, which completely isolates external pollutants, increases the operating time of the equipment, and saves the cost of equipment use.
