Description

A kind of hydraulic press

Technical field

The present invention relates to heavy industry equipment technical field, more particularly to a kind of hydraulic press.

Background technology

With the development of the society, the progress of technology, hydraulic press has consequence in production activity instantly.Hydraulic press It is a kind of machinery that the products such as metal, plastics, rubber, timber, powder are processed using hydrostatic pressure.It is usually used in forging and stamping, The compactings such as punching press, cold-extruded, alignment, bending, flange, process of sheet drawing, powder metallurgy, press fitting and forming technology.But traditional liquid Not in time, hand is put in hydraulic press to press safeguard measure by imprudence someone when operating, so as to cause personal injury.

The content of the invention

The technical problems to be solved by the invention are to overcome prior art defect, there is provided a kind of hydraulic press, with solution Problem is stated, the present invention uses following technical scheme to achieve the above object:

A kind of hydraulic press, including liquid-filled tank, hydraulic cylinder, telescopic hydraulic bar, infrared detector, lifting platform, workbench, bottom Seat, damping spring, rubber pad, guide post, sliding block, pipeline, hydraulic pump and controller, the liquid-filled tank are connected by pipeline and hydraulic pump Connect, the hydraulic pump input terminal is connected with controller output end, the output terminal of the infrared sensor and the input terminal of controller Connection, the hydraulic cylinder is partly in embedded liquid-filled tank, so that liquid-filled tank is hydraulic cylinder pressure supply, the telescopic hydraulic bar works as hydraulic pressure Flexible operation is carried out when pressure reaches fixed value in oil cylinder, and then promotes lifting platform to move up and down, the lifting platform passes through sliding block It is fixed on guide post, the damping spring is installed on the bottom of guide post, and the guide post is installed on base by damping spring, institute Rubber pad is stated below base.

On the basis of above-mentioned technical proposal, control circuit and detection circuit are set in the controller, the control circuit is adopted With special infraluminescence pipe and common infraluminescence pipe operation principle on the contrary, the usually light direct irradiation of infraluminescence pipe VD1 On infrared receiver tube VD2, equivalent to LSE 1., 2. foot is separated, the 4. foot of its LSE is just changed into low level, at this time three pole Pipe VT is turned on, and J is attracted, and hydraulic pump is powered to pressurize to liquid-filled tank.When having foreign matter insertion, cause the light on VD2 to disappear, cause The internal resistance of VD2 reduces, equivalent to 1., 2. ganging up between foot for LSE, the 4. foot output high level of LSE at this time, and triode VT cut-offs, Relay J is in release conditions, and hydraulic pressure air pump inoperative, extracts foreign matter, and hydraulic pump works on, and the detection circuit, which is worked as, foreign matter In the presence of, infrared detector just sends alarm with two transistors and a converter.Transistor Q1 forms brilliant control vibration Device, with piezoelectric sender XDC(It includes Liang Ge piezo-electric crystals area)A part be crystal.Converter has three independent to draw Line, connects a lead on each crystal, and the 3rd lead is then the common lead of two crystal.Less crystal inside area It is set as working frequency, and larger component is then driven by Q1, one provides big audio output.Pnp transistor is turned on, Pnp transistor Q2 must also be turned on, to by add the method for normal bias make transistor Q2 turn on, only need to be in the collector of Q2 To an indirect resistance of Q1, this base stage to Q2 adds a back bias voltage, and resistance used is foreign matter to be measured, and foreign matter makes Q2 is turned on, and Q2 turns on Q1 again, and as a result during abnormal contact infrared ray, exchanger just sends loud sound.

On the basis of above-mentioned technical proposal, the damping spring compresses spring using steel wire, is subject to the spiral shell of axial compressive force Spring is revolved, the material section used in it is mostly circle, and spring is generally equal pitch, and compressing between the circle of spring and circle has necessarily Gap, when being subject to external applied load spring contraction deform, store deformation energy.

On the basis of above-mentioned technical proposal, the lifting platform and workbench use wolfram steel.

The present invention is reasonable in design, simple to operate, can not only effectively reduce the generation of contingency, reduces Injury of the machine to human body, while reduce pollution of the noise to surrounding environment when in use, so as to effectively improve the work of worker Make efficiency, while can also effective damping.
