It is a kind of to utilize hydrostatic pressure to process the machinery of the goods such as metal, plastics, rubber, timber, powder.It is usually used in forging and stamping,
Punching press, cold-extruded, alignment, bending, flange, process of sheet drawing, powder metallurgy, compacting and the forming technology such as press-fit.But traditional liquid
Not in time, imprudence has people that hands puts in hydraulic press to press protective measure when operating, thus causes personal injury.
Summary of the invention
The technical problem to be solved is to overcome prior art defect, it is provided that a kind of hydraulic press, on solving
Stating problem, the present invention is by the following technical solutions for achieving the above object:
A kind of hydraulic press, including topping up case, hydraulic jack, telescopic hydraulic bar, infrared detector, lifting platform, workbench, base,
Damping spring, rubber blanket, guide pillar, slide block, pipeline, hydraulic pump and controller, described topping up case is connected with hydraulic pump by pipeline,
Described hydraulic pump input is connected with controller output end, and the outfan of described infrared sensor connects with the input of controller
Connecing, described hydraulic jack half embeds in topping up case, thus topping up case is hydraulic jack voltage supply, and hydraulic oil worked as by described telescopic hydraulic bar
In cylinder, pressure reaches to carry out flexible operation during fixed value, and then promotes lifting platform to move up and down, and described lifting platform is solid by slide block
Being scheduled on guide pillar, described damping spring is arranged on the bottom of guide pillar, and described guide pillar is arranged on base by damping spring, described
Rubber blanket is arranged on below base.
On the basis of technique scheme, setting control circuit and testing circuit in described controller, described control circuit is adopted
Contrary with special infraluminescence pipe and common infraluminescence pipe operation principle, the light direct irradiation of infraluminescence pipe VD1 at ordinary times
On infrared receiver tube VD2, be equivalent to LSE 1., 2. foot separated, the 4. foot of its LSE just becomes low level, now three pole
Pipe VT turns on, J adhesive, and hydraulic pump is energized and pressurizes to topping up case.When having foreign body to insert, cause the light heading line off on VD2, cause
The internal resistance of VD2 reduces, be equivalent to LSE 1., 2. gang up between foot, the now 4. foot output high level of LSE, audion VT ends,
Relay J is in release conditions, hydraulic pressure air pump inoperative, extracts foreign body, and hydraulic pump works on, and described testing circuit is when there being foreign body
In the presence of, infrared detector just sends chimes of doom with two transistors and a changer.Transistor Q1 constitutes crystalline substance control vibration
Device, with piezoelectric sender XDC(, it includes Liang Ge piezoquartz district) a part be crystal.Changer has three independent drawing
Line, each crystal connects a lead-in wire, and the 3rd lead-in wire is then the common lead of two crystal.Less crystal inside district
Being set as that operating frequency, bigger parts are then driven by Q1, one provides big audio frequency output.Pnp transistor to be made turns on,
Pnp transistor Q2 also must turn on, and wants to make transistor Q2 turn on by the method adding normal bias, only need to be at the colelctor electrode of Q2
To an indirect resistance of Q1, this adds a back bias voltage to the base stage of Q2, and resistance used is i.e. foreign body to be measured, and foreign body makes
Q2 turns on, and Q2 makes again Q1 turn on, and during result abnormal contact infrared ray, exchanger just sends loud sound.
On the basis of technique scheme, described damping spring uses steel wire compression spring, is subject to the spiral shell of axial compressive force

Detailed description of the invention
With specific embodiment, the present invention is further elaborated below in conjunction with the accompanying drawings.
A kind of hydraulic press, including hydraulic fluid tank 1, hydraulic jack 2, telescopic hydraulic bar 3, infrared detector 4, lifting platform 5, work
Platform 6, base 7, damping spring 8, rubber blanket 9, guide pillar 10, slide block 11, pipeline 12, hydraulic pump 13 and controller 14, described hydraulic pressure
Case 1 is connected with hydraulic pump 13 by pipeline 12, and described hydraulic pump 13 input is connected with controller 14 outfan, described infrared inspection
The outfan surveying device 4 is connected with the input of controller 14, and described hydraulic jack 2 half embeds in hydraulic fluid tank 1, thus hydraulic fluid tank 1
For hydraulic jack 2 voltage supply, described telescopic hydraulic bar 3 when in hydraulic jack 2 pressure carry out flexible operation when reaching fixed value, and then
Promoting lifting platform 3 to move up and down, described lifting platform 5 is fixed on guide pillar 10 by slide block 11, and described damping spring 8 is arranged on leads
The bottom of post 10, described guide pillar 10 is arranged on base 7 by damping spring 8, and described rubber blanket 9 is arranged on below base 7.
Further, setting control circuit and testing circuit in described controller 14, described control circuit uses special infrared
Light pipe and common infraluminescence pipe operation principle are contrary, and the light direct irradiation of infraluminescence pipe VD1 is at infrared receiver at ordinary times
On pipe VD2, be equivalent to LSE 1., 2. foot separated, the 4. foot of its LSE just becomes low level, now audion VT conducting, and J inhales
Closing, hydraulic pump 13 is energized and pressurizes to hydraulic jack 2, when having foreign body to insert, causes the light heading line off on VD2, causes the internal resistance of VD2
Reduce, be equivalent to LSE 1., 2. gang up between foot, the now 4. foot output high level of LSE, audion VT ends, at relay J
In release conditions, hydraulic pump 13 does not works, and extracts foreign body, and hydraulic pump 13 works on, and described testing circuit is when with the presence of foreign body
Time, infrared detector just sends chimes of doom with two transistors and a changer, and transistor Q1 constitutes crystal controlled oscillator, uses
Piezoelectric sender XDC(it include Liang Ge piezoquartz district) a part be crystal, changer has three independent lead-in wires, each
Connecting a lead-in wire on crystal, the 3rd lead-in wire is then the common lead of two crystal, and less crystal inside district is set as work
Working frequency, bigger parts are then driven by Q1, and one provides big audio frequency output, and pnp transistor to be made turns on, pnp transistor
Q2 also must turn on, and wants to make transistor Q2 turn on by the method adding normal bias, only need to be between current collection best Q1 of Q2
Connecing a resistance, this adds a back bias voltage to the base stage of Q2, and resistance used is i.e. foreign body to be measured, and foreign body makes Q2 turn on,
Q2 makes again Q1 turn on, and during result abnormal contact infrared ray, exchanger just sends loud sound.
Further, described damping spring 8 uses steel wire compression spring, is subject to the helical spring of axial compressive force, used by it
Material section be circular, spring is generally equal pitch, and the circle of compression spring has certain gap between circle, when by outward
Spring contraction deformation during load, stores deformation energy.
Further, described lifting platform 5 and workbench 6 use wolfram steel.
Present configuration is reasonable in design, simple to operation, the effective minimizing concussion damage to machine, reduces simultaneously and makes an uproar
Sound pollutes, it is most important that is effectively reduced hydraulic press and accidentally injures the accident generation of workman.
The above is present pre-ferred embodiments, for the ordinary skill in the art, according to the present invention's
Teaching, in the case of principle and the spirit without departing from the present invention, the change that carried out embodiment, revises, replaces and becomes
Within type still falls within protection scope of the present invention.
