Abstract
The invention relates to a hydraulic press with two beams and four pillars. The invention is characterized in that the machine body of the invention consists of an upper beam, a sliding block, a lower beam and an up stand pillar support arranged at the four corners of the upper beam, the sliding block and the lower beam, as well as an oil cylinder with driving effect. The bottom of the sliding block is provided with an upper moulding plate and the lower beam is provided with a lower moulding plate. The upper end of the oil cylinder is fixed onto the sliding block and the lower end is connected with the lower beam. The upper part, central part and the lower part of a piston mechanism are respectively an upper piston rod, a piston head and a lower piston rod. The upper end of the upper piston rod is fixedly connected with the upper beam and the lower piston rod is fixedly connected with the lower beam. The piston mechanism is internally provided with two oil inlet holes, the lower end of the one of which is communicated with a lower ring-shaped space between the piston head and the lower piston rod. The lower end of the other oil inlet hole is communicated with the upper ring-shaped space between the piston head and the upper piston rod. The invention has the advantages that the invention not only has the supporting effect of an upright post and replaces the four upright posts of the four pillars hydraulic press, but also scatters the stressed points of the sliding block and the lower beam and also reduces the stressed force. In addition, the invention further simplifies the structure of the hydraulic press and reduces the manufacturing cost; therefore, the invention is particularly suitable for being used as the hydraulic press with light tonnage and large sized processing area.

Background technology
At present known three beam and four-post hydraulic machine pressing machines mainly are to be made of entablature, slide block, sill and four columns being packed between them, oil cylinder is installed between entablature and the slide block, the piston rod of oil cylinder connects slide block, and drives slide block and pump along column, finishes the compacting to workpiece.Because the cylinder body of oil cylinder is installed on the entablature, then will entablature have the installing hole of oil cylinder, be the strength and stiffness that guarantee entablature, needing increases height with entablature; Because entablature, slide block and sill all belong to stressed member, the thickness that therefore needs to increase gusset on each beam so just causes the height of complete machine to increase, and has the deficiency that manufacturing cost is high and consumptive material is many to satisfy its requirement of strength simultaneously.In addition, because the hydraulic press of the special product of processing needs little tonnage oil cylinder and big work top type, its stress point is concentrated, and needs to maintain a certain distance between entablature and the slide block, needs that therefore four columns are processed into certain height and could satisfy aforementioned requirement; Welding procedure and machined between three beams, four posts all need a large amount of man-hours, so that above-mentioned hydraulic press exists is consuming time, effort and the high defective of manufacturing cost.
Summary of the invention
The present invention is suitable for little tonnage, the big mach two-beam and four-post hydraulic machine pressing machine of table top for what solve that the technical problem that exists in the known technology provides a kind of simple in structure, low cost of manufacture.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
Two-beam and four-post hydraulic machine pressing machine, it is characterized in that: the hydraulic press fuselage is by entablature, slide block, sill and be installed in entablature, the oil cylinder that plays column support and driving effect at four jiaos of places of slide block and sill constitutes, slider bottom is equipped with cope match-plate pattern, lower bolster is installed in corresponding cope match-plate pattern position above the sill, described oil cylinder comprises: cylinder body and piston mechanism, the cylinder body upper end is fixed with upper cylinder half mouth guide pin bushing, and be fitted in four jiaos of places of slide block by the slide block flange, described piston mechanism top is upper piston rod, the middle part is a piston head, the bottom is a lower piston rod, the fixedly connected entablature in upper piston rod upper end, the fixedly connected sill in lower piston rod lower end, in piston mechanism, be provided with two fuel feed holes that its upper end is communicated with fuel tank, one of them fuel feed hole lower end is communicated with the following annular space between piston head and the lower piston rod, and another fuel feed hole lower end is communicated with the last annular space between piston head and the upper piston rod.
The present invention can also adopt following technical scheme:
Four jiaos of places of described entablature are shaped on T shape hole, and the entablature flange is fastening by T shape hole and entablature, and entablature flange bottom is shaped on T shape hole, and the upper piston rod upper end is shaped on shoulder, and piston mechanism is fixed in the entablature flange T shape hole by the shoulder of upper piston rod.
Four jiaos of places of described sill are shaped on T shape hole respectively, and lower piston rod is installed in the T shape hole of four jiaos of sills, and fastening by the sill locknut.
Corner location on sill is equipped with the position limitation protection piece, and lower piston rod is threaded onto the position limitation protection piece.
Advantage and good effect that the present invention has are: because the present invention adopts entablature, slide block and four jiaos of places of sill that the cylinder structure that integrates column carrying and pressing function is installed, in piston mechanism, be provided with the fuel feed hole that is communicated with fuel tank, the lower end of two fuel feed holes is communicated with following annular space between piston head and the lower piston rod and the last annular space between piston head and the upper piston rod respectively, variation by two annular space hydraulic oil moves up and down cylinder body, and then drive the slide block upstream or downstream, finish compacting to workpiece.Because the upper end and the entablature of piston rod are fixed, lower end and sill are fixed, and not only play the supporting role of column, substitute four columns of four-column hydraulic press, the stress point of slide block and sill is disperseed, and alleviate.Adopt said structure in addition, need not on entablature, to open the oil cylinder installing hole and expend lot of materials, further simplified the structure of hydraulic press and the manufacturing procedure between its three beams, four posts, reduced the manufacturing cost of hydraulic press with increasing its height and intensity.Therefore the present invention is specially adapted to little tonnage, the big mach hydraulic press of table top.
