Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] refer to figure 1 The improved type shown is a closed pressurized oil supply profile extrusion machine, including a fixed seat 1, an extrusion mechanism 2 and an oil supply system 3, and the extrusion mechanism 2 includes a main cylinder 21 and an auxiliary cylinder 22 and pressure beam 23; the oil supply system 3 includes an oil pump group 31 and an oil storage tank 32, the oil storage tank 32 supplies oil to the master cylinder 21 through a filling valve 4, and the oil storage tank 32 is composed of a A sealed pressurized oil cylinder 321 and a sealed return oil tank 322 are formed. The pressurized oil cylinder 321 is fixed at one end of the master cylinder 21 and fixed as one with the master cylinder 21. The return oil tank 322 is located above the pressurized oil cylinder 321. A hydraulic oil flow channel 5 is provided between the oil return tank ...

Abstract

The present invention relates to an improved profile extruder adopting closed pressurized oil supply, which includes a fixed seat, an extrusion mechanism and an oil supply system. The extrusion mechanism includes a main cylinder, an auxiliary cylinder and a pressure beam; The oil supply system includes an oil pump group and an oil storage tank, the oil storage tank supplies oil to the main cylinder through a filling valve, and the oil storage tank is composed of a pressurized oil cylinder and a return oil tank, both of which are sealed. The pressurized oil cylinder is set at one end of the main cylinder and fixed as one with the main cylinder, the oil return tank is located above the pressurized oil cylinder, and a hydraulic oil flow channel is provided between the oil return tank and the pressurized oil cylinder, and the channel functions Because the hydraulic oil flows back and forth between the oil return tank and the pressurized oil cylinder; part of the filling valve is fixed on the main cylinder, and the other part is located in the pressurized oil cylinder, so that the hydraulic oil in the pressurized oil cylinder directly passes through the filled valve Supply oil to the master cylinder. The invention simplifies the oil supply system of the extruder, greatly reduces the hydraulic oil quantity of the extruder, reduces production and use costs, and makes the structure more reasonable and compact.

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 structure of the traditional extrusion machine is relatively complicated, the cost is high, the stroke is long, the working efficiency is low, and the upper open oil tank is used, which consumes a lot of oil, so it has: 1. When the main engine is in standby, it will produce useless work; 2. The oil pump The service life will be shortened when working or idling for a long time; 3. The hydraulic oil will generate heat when the main engine is in standby and the motor is idling, which is not conducive to energy saving and environmental protection, and saves use costs and other defects. In order to avoid the defects of traditional extruders, the applicant applied for an invention patent application (application number "201510085356.4") for "energy-saving, high-efficiency, closed-type pressurized oil supply profile ext...
