Description
Technical field
The utility model relates to rubber weather strip production equipment technical field.
Background technology
At present, rubber weather strip is a kind of seal that is widely used in automotive window, container, plant equipment, building doors and windows indispensability, and when the turning occurring in the position that sealing strip is installed, sealing strip also will have corresponding turning.Rubber weather strip at first is through Rubber Extruder in process of production, processes linear sealing strip semi-finished product, then according to angle or the shape of the position of installing.When sealing strip will be installed in the position at turning, this just need finish with connecing the angle machine, and the course of work that connects the angle machine is as follows:
1, with two linear sealing strip semi-finished product put into connect the angle machine connect the angle mould tool, Mode-locking oil cylinder is with mold-locked then;
2, in mold cavity, the sizing material in the mold cavity is through pressurize, heating, sulfuration, typing with the sizing material high-pressure injection for the material feeding oil cylinder;
3, cope match-plate pattern separates with lower bolster, and mold open takes out goods.
Tradition connects the angle machine and often occurs in operating process because can not automatic pressure-controlledly causing hydraulic fluid temperature too high, though adopt air-cooled technology, but still do not reach ideal temperature.And because of can not automatic speed regulation, cause excessive or unbalance the causing of speed of pressure to connect angle product distortion in the material feeding process, percent defective increases.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiency that existing traditional rubber weather strip connects the angle machine, but thereby provides that a kind of course of work hydraulic fluid temperature is normal, material feeding process pressure control can guarantee that the rubber weather strip that connects the cutin amount connects the angle machine.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of rubber weather strip connects the angle machine, comprise and connect the angle Rack Body, formation system, hydraulic system, hydraulic system comprises quantitative hydraulic pump, motor, overflow valve, stop valve, Pressure gauge, the pressing mold oil cylinder, bidirectional hydraulic lock, the material feeding oil cylinder, it is characterized in that also comprising a M function three position four-way directional control valve, the 2nd M function three position four-way directional control valve, the one M function three position four-way directional control valve and the 2nd M function three position four-way directional control valve all are connected in the oil circuit, and the control oil circuit of pressing mold oil cylinder is connected with a M function three position four-way directional control valve; The control oil circuit of material feeding oil cylinder is connected with the 2nd M function three position four-way directional control valve; Quantitative hydraulic pump in the hydraulic system is the low discharge gear pump; The other adjustable throttling that connects on the material feeding oil cylinder oil circuit.
Further, adopt the series connection of an above-mentioned M function three position four-way directional control valve and the 2nd M function three position four-way directional control valve oil circuit, pressing mold oil cylinder and material feeding oil cylinder be not when commutating like this, hydraulic oil leads to two direct oil sump tanks of M function three position four-way directional control valve, and the oil circuit drain charge can not make hydraulic fluid temperature raise like this.It is two O function metas sealing magnetic valve in parallel in oil circuit that tradition connects the angle machine, and oil circuit is not when commutating like this, and the oil that oil pump comes out can only keep the certain pressure oil sump tank by overflow valve because have hydraulic fluid pressure always very conference cause oil warm too high.
Further, tradition connects adjustable throttling and the series connection of material feeding oil cylinder of angle machine, material feeding process speed is constant, and the other adjustable throttling that connects on the material feeding oil cylinder oil circuit of the present utility model is opened very little flow, when hydraulic fluid pressure is very big like this, material feeding speed will be slack-off automatically, pressure hour accelerates automatically, realizes the automatic conversion of the speed of material feeding process.
The beneficial effects of the utility model are, rubber weather strip connect in the machine course of work of angle hydraulic fluid temperature can be not too high, course of work hydraulic fluid temperature normal, but thereby material feeding process pressure control can guarantee to connect cutin amount material feeding speed and can control automatically, connect the angle product and can not be out of shape because of imbalance of pressure, percent defective is low.
