Abstract

The utility model discloses a wire wrapped brick-press machine structure, which comprises an upper beam, an upright pillar and a lower beam, wherein, a piston rod is fixed on the lower side of the upper beam. A piston tank is covered outside the piston rod. The piston tank is connected with a moving beam into a whole. The utility model is characterized in that the piston rod is directly fixed with the upper beam, a high voltage oil passage is arranged inside the upper beam, and is communicated with the high voltage oil passage in the piston rod. The utility model saves an interim plate between the upper beam and the piston rod; therefore, the height of the brick-press machine is reduced. The weight of the brick-press machine is reduced and the rigidity of a stander is improved, thereby simplifying the structure, increasing sealing function and reducing cost.

Description

Steel wire wound form brick machine

Technical field

The utility model relates to the brick machine structure, particularly the structure of steel wire wound form brick machine.

Background technology

Referring to Fig. 1,2, steel wire wound form brick machine comprises by steel wire 3 winding all-in-one-pieces upper beams 1, column 2 and underbeam 32, be provided with fuel tank 4 in the

upper beam

1,1 below of putting the beams in place is fixed with piston rod 5, offer high-pressure oil passage 6 in the piston rod 5, piston rod 5 overcoats piston cylinder 7, and piston cylinder 7 links into an integrated entity with moving beam 8, can slide up and down along piston rod 5.At present, known this brick machine structure all put the beams in place 1 with piston rod 5 between an excessive plate 9 is installed, excessively offer high-pressure oil passage 10 in the plate 9, and be communicated with the interior high-pressure oil passage 6 of piston rod 5.It is fixing that excessively the upper and lower faces of plate 9 is used screw 11,12 and upper beam 1 and piston rod 5 respectively, and adopt big specification planar seal ring 13,14 to seal, excessively between plate 9 and the upper beam 1 two huge alignment pins 15 need be set also, to provide excessive plate sufficient intensity to bear eccentric load, excessively then locate between plate 9 and the piston rod 5 by the cylinder boss 16 of piston rod 5.There is following shortcoming in this known technology: 1. between upper beam 1 and the piston rod 5 excessive plate 9 is installed, makes the whole frame of brick machine higher, reduced the rigidity of steel wire winding prestressed structure frame; 2. for bearing high pressure, excessively plate 9 is made with forging usually, and weight is big, has increased the weight of brick machine greatly; 3. excessively two huge alignment pins 15 need be set, the processing and manufacturing difficulty between plate 9 and the upper beam 1; 4. excessively the upper and lower surface of plate 9 all will adopt big specification planar seal ring 13,14, and the leakage of oil chance is many.

Summary of the invention

The purpose of this utility model provides a kind of and existing steel wire wound form brick machine and compares, and highly reduction, housing rigidity improve, the steel wire wound form brick machine of weight saving.

The utility model is achieved in that steel wire wound form brick machine comprises by steel wire winding all-in-one-piece upper beam, column and underbeam, be provided with fuel tank in the upper beam, be fixed with piston rod below putting the beams in place, offer high-pressure oil passage in the piston rod, the piston rod overcoat piston cylinder, piston cylinder and moving beam link into an integrated entity, can slide up and down along piston rod, especially, piston rod is directly fixing with upper beam, in putting the beams in place, be provided with high-pressure oil passage, and be communicated with high-pressure oil passage in the piston rod.The utility model is owing to saved the excessive plate that is connected in the prior art between upper beam and the piston rod, therefore reduced the brick machine height, alleviated the weight of brick machine greatly, the rigidity formula that twines the prestressed structure frame according to steel wire as can be known in addition, bracket height reduces, and housing rigidity improves thereupon.

The height reduction, weight saving, the rigidity that the utility model has the advantages that frame not only improve, and because the huge alignment pin between having saved in the prior art excessive plate and having put the beams in place, so designs simplification, handling ease, cost reduction.Because piston rod is directly fixing with upper beam, therefore reduced sealing surface in addition, the leakage of oil chance greatly reduces, and has improved the reliability of brick machine.

The specific embodiment

Referring to Fig. 3,4, the upper beam 1 of steel wire wound form brick machine, column 2 and underbeam 32 are wound in one by steel wire 3, in upper beam 1, be provided with fuel tank 4, the below of upper beam 1 is direct and piston rod 5 is fixing, offers high-pressure oil passage 6 in the piston rod 5, and piston rod 5 overcoats piston cylinder 7, piston cylinder 7 links into an integrated entity with moving beam 8, can slide up and down along piston rod 5, be provided with high-pressure oil passage 17 in 1 putting the beams in place, this passage and piston rod 5 interior high-pressure oil passages 6 are communicated with.Be connected by long bolt 18 between the upper beam 1 of present embodiment and the piston rod 5.The upright opening that long bolt 18 passes upper beam 1 is tightened on the piston rod 5, and by nut 19 lockings.Bear eccentrically loaded ability for improving piston rod 5, present embodiment offers locating hole 20 in the bottom of upper beam 1, be provided with cylinder boss 21 at the top of piston rod 5, cylinder boss 21 inserts in the locating hole 20, and this mode with the cylinder boss location has improved piston rod 5 greatly and born eccentrically loaded ability.

As further improvement, present embodiment offers four casting technique holes 22, front and back that both sides are arranged at upper beam 1, this structure obviously is different from the frame mode in two holes 23, front and back of the center arrangement shown in Fig. 1,2, its advantage is to provide more position that long bolt 18 is installed, make long bolt 18 can be circle distribution equably, firmly hang piston rod 5.

Referring to Fig. 5, the high-pressure oil passage 17 that present embodiment is provided with in upper beam 1 is made of insertion hole 33 and high pressure intubate 24, and high pressure intubate 24 is communicated with the high-pressure oil passage 6 of piston rod 5 through angle coupling 25.High pressure intubate 24 plays the effect that hydraulic oil and upper beam casting body are separated.Angle coupling 25 can be fixed in the top of piston rod 5 with bolt 26.

For improving the sealing between piston rod 5 and the upper beam 1, present embodiment also is provided with sealing ring 27 between piston rod 5 and upper beam 1.

Operation principle of the present utility model is the same with prior art, summarize the brick machine course of work below in conjunction with Fig. 4: when moving beam 8 moves downward with piston cylinder 7, prefill valve 28 in the piston rod 5 is opened, oil in the fuel tank 4 enters the master cylinder cavity volume by prefill valve 28, realize quick topping up, prefill valve 28 cuts out then, enters master cylinder from the hydraulic oil of valve module 29 by high pressure intubate 24 and the high-pressure oil passage in piston rod 6, realizes pressure process; After pressing process finishes, little ring chamber 31 oil-feeds that piston rod 5 and piston cylinder 7 and flange 30 contain, piston cylinder 7 promptly moves upward together with moving beam 8, and this moment, prefill valve 28 was opened once more, oil in the master cylinder chamber flows back in the fuel tank 4 by prefill valve 28, and pressing unfired brick so circulates.
