Double frame-type brick machine rack constructions
Technical field
The present invention relates to a kind of rack construction of hydraulic press, and in particular to a kind of pair of frame-type brick machine frame knot
Structure.
Background technology
As depicted in figs. 1 and 2, the main stress rack construction of existing pair of frame-type brick machine is main before being arranged in parallel
Framework 11 and afterframe 12 connect integral by connection component.Front baffle 11 and afterframe 12 in figure use monoblock type
Frame structure, i.e., cut out closing inside casing 13 by whole steel plate and form, main oil necessary to brick machine is set in closing inside casing 13
Cylinder component 21 and workbench 22 etc.;And the connection component between two frameworks is mainly to be arranged on two framework medial surfaces, four angles position
Sleeve 31 and long bolt-nut combination 32:Its middle sleeve 31 is arranged between two block frames, and its two ends is respectively implanted in framework
In the positioning hole 14 of side, for positioning and scaffold;Long bolt is then locked through two block frames and sleeve and with big nut,
Make front and rear two block frames connection integral.The master cylinder 21 of brick machine is installed on the top surface of closing inside casing 11, and blending bolt is solid
Fixed, master cylinder component 21 is provided with replenishing valve 212 built with piston 211, its top, and bottom is then provided with flange 213;Master cylinder
Piston 211 and the moved cross beam 214 of upper die head link into an integrated entity and can move up and down.The workbench 22 of brick machine is installed on envelope
The bottom surface blending bolt for closing inside casing is fixed.The top tank 23 of brick machine is arranged between two frameworks 1 and positioned at the upper of master cylinder 21
Side, top tank 23 is connected by flange passage 24 with master cylinder 21.The operation principle of the brick machine is:When need carry out pressed brick
When base is acted, replenishing valve is opened, and the hydraulic oil in top tank enters the rodless cavity of master cylinder by flange passage and through replenishing valve,
Make piston driving moved cross beam rapid decrease, realize quick matched moulds;Then, replenishing valve is closed, and the pressure oil from system is through special
Enter the rodless cavity of master cylinder with oil duct to realize that compacting is acted.After the completion of compacting, replenishing valve is again turned on, and master cylinder has
Rod cavity enters system pressure oil, and piston driving moved cross beam, which rises, realizes the demoulding.
But, the brick machine rack construction using above-mentioned attachment structure can have following lack after long-time use
Point:1st, the rigidity of rack construction has obvious difference in left and right directions and fore-and-aft direction:Because framework is cut by monoblock steel plate
Form, therefore the rigidity of left and right directions is enough, and the rigidity of four group pull bar sleeve of the fore-and-aft direction because connecting two block frames is relatively
It is weak, therefore cause the fore-and-aft direction rigidity of frame poor, before and after the powder that the feed system of brick machine is distributed into die cavity occurs not
When, because front and rear frame stressing is uneven and produces relative offsetting after frame carrying, there is frame when as a result causing brick machine to work
Front and rear shaking phenomenon;" nodding " is commonly called as, phenomenon of " being nodded " when unbalance loading is serious is more obvious;Further, due to the feeding of brick machine
The powder that system is distributed into die cavity can not possibly be accomplished to idealize, the uneven phenomenon of the more or less presence of meeting, therefore this frame
Long-term region of bearing in the positioning hole of sleeve and the threaded portion of pull bar all to grade after unbalance loading produces stress concentration and caused tired
Strain bad phenomenon;2nd, because frame bears " nodding " phenomenon for occurring after unbalance loading, the connection spiral shell of master cylinder and workbench is also resulted in
The problem of bolt occurs being easy to fracture, substantially reduces the reliability of main machine structure.
The content of the invention
It is existing to solve it is an object of the invention to provide a kind of double frame-type brick machine rack constructions of improved structure
The weak point of technology.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that:
Double frame-type brick machine rack constructions, including:Put down before and after front baffle and afterframe, the front baffle and afterframe
Row arrangement;Connection component, to front baffle and afterframe connection is integral;The medial surface of the front baffle is provided with least
Two front boss, the medial surface of the afterframe is identical with the front boss and corresponding laminating therewith rear convex provided with quantity
Platform, provided with a positioning component between each front boss and corresponding rear boss.
Preferably, the positioning component includes the positioning keyhole being separately positioned on the binding face of front boss and rear boss
With the positioning key being arranged in positioning keyhole.
Further, the front boss is used and is arranged on front baffle integrally casting mode or welding manner or mosaic mode
On front baffle;The rear boss uses and is arranged on afterframe with afterframe integrally casting mode or welding manner or mosaic mode
On.
Preferably, each front boss and each rear boss are equipped with the gusset of increase strength and stiffness.
As one kind selection, the front baffle and afterframe are integral frame structure.
Alternatively, the front baffle and afterframe are steel wire winding pre-stressed concrete frame structure.
As a preferred embodiment, the medial surface of the front baffle is provided with four front boss, two of which front boss is with front frame
The vertical center line of frame is that symmetry axis is symmetricly set at the preceding upper beam of front baffle, and another two front boss is with the vertical center line of front baffle
It is symmetricly set on for symmetry axis at the preceding underbeam of front baffle.
As it is another preferably, the medial surface of the front baffle is set provided with two front boss, one of front boss
At the preceding upper beam of front baffle, its vertical center line is overlapped with the vertical center line of front baffle;Another front boss is arranged on front baffle
Preceding underbeam at, its vertical center line is overlapped with the vertical center line of front baffle.
As another preferably, the medial surface of the front baffle is provided with three front boss, two of which front boss size
Identical and using front baffle vertical center line is symmetricly set at the preceding upper beam of front baffle as symmetry axis;3rd front boss size compared with
Another two front boss is big and is arranged at the preceding underbeam of front baffle, and its vertical center line is overlapped with the vertical center line of front baffle.
Preferably, the connection component is the combination of at least four long bolts-nut, and long bolt is through forward and backward
Framework.
The present invention can effectively solve the problem of double type rack fore-and-aft direction rigidity are weaker by using said structure,
And then improve the offset load resistance of frame, it is ensured that the compact dimensions precision and quality of adobe during compacting.
