Abstract
The frameless hot press is characterized by that the top beam joined together with top pressure plate is directly fixedly connected together with piston rod, and the piston rod not only can be used to drive the top beam to make it move upwards and downwards, but also can be used for directly bearing the weight of whole top beam, so that said invention possesses the advantages of simple structure, low production cost, convenient installation and long service life, etc..
Description
The invention belongs to pressure rolling machinery, in particular for the hot press technical field of structures of pressboard section bar.
Existing hot press mainly contains two kinds of structures, and a kind of is column, and another kind is a frame-type.
The top board of vertical rod formula hot press supports (see figure 3) by several columns, oil cylinder is fixed on column top, the defective that this structure exists is that the reaction of press power comes balance by column, the column bar is subjected to huge tensile force, the fastening requirement of the nut column of fastening column bar is than higher, and design and manufacturing all will have specific (special) requirements.The installation of column bar also needs to guarantee perpendicularity and axiality, and this just all brings difficulty to equipment design, manufacturing and installation; The frame-type hot press is to come the support works platform and be connected the top board (see figure 4) with one group of large structure frame.It is high especially that the weak point of this structure is that technical plane precision to each frame supported workbench requires, this just gives in the processing and brings difficulty, generally all be that the combination of all frameworks is clipped together with boring machine and processed this plane, to guarantee its flatness, but production cost height, and when installing in order to guarantee each framework machined surface plane that exists together, the means of taking are also very complicated.
Purpose of the present invention provides a kind of hot press of new structure just for the weak point that overcomes above-mentioned prior art existence.Hot press of the present invention is jumped out traditional hot press design pattern, the column of column hot press and the framework of frame-type hot press have been cancelled, become Frameless hot press, thereby solved above-mentioned complexity and difficulty that the hot press structural member exists in design, the manufacturing and installation process.
The objective of the invention is to be achieved through the following technical solutions:
To directly be fixed together with the upper beam that top board links into an integrated entity with piston rod, piston rod had both driven to put the beams in place does upper and lower motion, directly support the weight of whole upper beam again, oil cylinder 3 is arranged on down in the girder construction, and lower platen places on the underbeam, when pressure oil enters the upper oil cavitie of oil cylinder, piston rod drives the down motion formation operating pressure of putting the beams in place, and material moulding between upper and lower pressing plate is when pressure oil enters lower oil cavitie, top board release, piston rod drive again to put the beams in place and rise to original position.
Further set forth content of the present invention below in conjunction with Figure of description and embodiment:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is a prior art column hot press structure diagram;
Fig. 4 is for being prior art frame-type hot press structure diagram.
Fig. 1～Fig. 2 label is:
1-top board 2-lower platen 3-oil cylinder 4-piston rod
5-upper beam 6-underbeam 7-upper oil cavitie 8-lower oil cavitie
9-nut 10-material
The present embodiment hot press is six cylinder formulas, and per two cylinders are one group.How many group numbers of oil cylinder 3 needs to decide on work area and pressure design, both can increase, and also can reduce, top board 1 is connected the below of upper beam 5, and top board is drilled with three groups of totally six holes together with upper beam, is used to insert piston rod 4, screw thread has been attacked on the piston rod top, cooperates with nut 9.The stage casing of piston rod both can be provided with step, also can take the hot charging stationary fit with upper beam, top board, prevented its downslide.Each piston-rod lower end piston inserts an oil cylinder 3, and oil cylinder is arranged in underbeam 6 structures, makes the entire equipment structure seem succinct, compact.Lower platen 2 places above the underbeam.Upper and lower pressing plate is corresponding to be placed.When the upper oil cavitie 7 of oil cylinder fed operating pressure oil, piston rod drove upper beam and top board down moves, and makes material 10 moulding between upper and lower pressing plate.When the lower oil cavitie 8 of oil cylinder fed pressure oil, piston rod drove upper beam and top board up moves, and the material unloading of moulding is put the beams in place and top board is thus lifted to the job initiation position, and whole one action stroke has just been finished.
The present invention has that production cost is low, structure is simple compared with prior art Single, be easy to install the obvious advantage with long service life.
Claims (3)
1, Frameless hot press, form by top board 1, lower platen 2, oil cylinder 3 and piston rod 4, it is characterized in that the upper beam 5 that fuses with top board 1 directly is fixed together with piston rod, piston rod 4 had both driven upper beam 5 and had done upper and lower motion, directly supported the weight of whole upper beam again.
2, hot machine according to claim 1 is characterized in that oil cylinder 3 is arranged in underbeam 6 structures, and lower platen 2 places on the underbeam 6.
3, according to the described hot press of claim, it is characterized in that the upper oil cavitie 7 of oil cylinder 3 is working oil chamber, lower oil cavitie 8 is for promoting oil pocket.
