Technical field
The utility model is related to a kind of four-column hydraulic press guider, and especially one kind can ensure that four-column hydraulic press adds
The guider of work precision, belongs to technical field of forging and pressing equipment.
Background technology
When four-column hydraulic press works, under hydraulic system effect, sliding block drives upper mould to be done along four guide pillars on fuselage
Up and down reciprocatingly move along a straight line, so as to realize the punching press to workpiece.Wherein be respectively equipped with guide pin bushing in the pilot hole of sliding block corner, guide pin bushing with
Sliding block is slided up and down along guide pillar, vibrates and impact frequent when being worked due to hydraulic press, adds the phase mutual friction between guide pin bushing and guide pillar,
In the course of time, guide pin bushing and guide pillar easily wear and tear, and the gap ultimately resulted between the two increases, and leverage the processing essence of hydraulic press
Degree.For above-mentioned situation, the method taken at present is to change guide pin bushing or guide pillar, reaches the purpose for reducing the two gap, but this side
Method is cumbersome, and labour intensity is high, and quantities is big, and maintenance cost is high.
Utility model content
The purpose of this utility model is to provide a kind of simple structure, low cost, easy to operate four-column hydraulic press is adjustable
Guider.
The utility model is achieved by the following technical programs：
A kind of four-column hydraulic press adjustable guiding device, the adjustable guiding device is separately positioned on four-column hydraulic press cunning
In the pilot hole of block corner, the adjustable guiding device includes fixed cover, adjustable guide pin bushing and gland, and the fixed cover is fixed on sliding block
In pilot hole, adjustable guide pin bushing is sleeved in fixed cover, and adjustable guide pin bushing is cylindrical to be coordinated with fixed cover internal conical surface, adjustable guide pin bushing inner circle
It is slidably connected with hydraulic press guide pillar, adjustable guide pin bushing upper flanges side is connected with slider guide hole top bar, gland passes through hydraulic press
Guide pillar is fixed and covered on the upside of slider guide hole.
The purpose of this utility model can also further be realized by following technical measures.
Foregoing four-column hydraulic press adjustable guiding device, wherein the described cylindrical cone angle of adjustable guide pin bushing is 2 °~4 °.
Foregoing four-column hydraulic press adjustable guiding device, wherein described adjustable guide pin bushing upper flanges side and slider guide
Adjustment gap a between the top bar of hole is 4mm~6mm.
Foregoing four-column hydraulic press adjustable guiding device, wherein described adjustable guide pin bushing upper flanges side passes through several
Support screw and several adjusting screws are connected with slider guide hole top bar.
Foregoing four-column hydraulic press adjustable guiding device, wherein described fixed cover is supported on slider guide hole getting out of a predicament or an embarrassing situation
On, fixed set upper side is connected by several junction of the edges of two sheets of paper screws with sliding block.
The utility model be respectively provided with the pilot hole of four-column hydraulic press sliding block corner cone match fixed cover and can
Guide pin bushing is adjusted, simple structure, low cost is easy to operate.When gap increases between adjustable guide pin bushing and hydraulic press guide pillar, pressure only need to be opened
Lid, unscrews supporting screw, by each adjusting screw can gap between the adjustable guide pin bushing of easy adjustment and hydraulic press guide pillar, so as to ensure
The machining accuracy of hydraulic press, it is not only time saving and energy saving, and also workload is small, and labour intensity is low.Additionally, the adjustable cylindrical cone angle of guide pin bushing
It it is 2 °~4 °, it is ensured that adjustable guide pin bushing and fixed cover cone match are even closer, regulation gap is more accurate.Adjustable guide pin bushing upper end
Adjustment gap a between flange and slider guide hole top bar is 4mm~6mm, so can adjust adjustable according to actual conditions
Gap in the reasonable scope, is further ensured that hydraulic pressure machining accuracy between guide pin bushing and hydraulic press guide pillar.
Advantage of the present utility model and feature, will carry out diagram reconciliation by the non-limitative illustration of preferred embodiment below
Release, these embodiments, be only given as an example referring to the drawings.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model is separately positioned in 1 four jiaos of pilot holes 11 of four-column hydraulic press sliding block, including it is solid
Surely 2, adjustable guide pin bushing 3 and gland 4 are covered.Fixed cover 2 is supported on the getting out of a predicament or an embarrassing situation on 12 of slider guide hole 11, and its upper end is ridden by several
Seam screw 21 is connected with sliding block 1, and adjustable guide pin bushing 3 is sleeved in fixed cover 2, and adjustable guide pin bushing 3 is cylindrical to match somebody with somebody with the internal conical surface of fixed cover 2
Close, the inner circle of adjustable guide pin bushing 3 can be slided up and down along hydraulic press guide pillar 5, the upper flanges side of adjustable guide pin bushing 3 passes through several supporting screws 31
Top bar 13 with several adjusting screws 32 and slider guide hole 11 is connected.Wherein the cylindrical cone angle of adjustable guide pin bushing 3 is 2 °~4 °,
α is 3 ° in the present embodiment, and the adjustment gap a between the upper flanges side of adjustable guide pin bushing 3 and the top bar 13 in slider guide hole 11 is
