Interior forcing press
The utility model belongs to machining equipment field, more particularly to a kind of interior forcing press.
At present, in pipe fitting processing, easily there is unbalance stress in whens compacted products, and homogeneity of product is poor, serious shadow
Ring the quality of product.In addition, general large-scale four guide posts forcing press realizes the upper of workbench all with the lifting of three hydraulic pistons
Lower movement, this requires that the movement of three pistons must be synchronous, no it will cause platform movement is uneven.Therefore, now there is an urgent need for
A kind of interior forcing press that design is scientific and reasonable.
Utility model content
The utility model proposes a kind of interior forcing press, solve and suppress that tubing products uniformity is poor, produces in the prior art
The problem of efficiency is low.
What the technical solution of the utility model was realized in：A kind of interior forcing press, including arch frame, the arch machine
Upper pressure platform and lower pressure platform are equipped with frame, the lower pressure platform is fixed setting, and the upper pressure platform can be in institute
State oscilaltion in arch frame, be equipped with four guide rails in the arch frame, the upper pressure platform can be along leading described in four
Rail moves, and the upper pressure platform center of top is connected with pressure plunger, and the pressure plunger both sides are respectively provided with a lifting piston,
The pressure plunger and the lifting piston are connected by oil pipe with hydraulic oil container, and the upper pressure platform bottom is equipped with upper mold
Have groove, lower mold slots are equipped with the lower pressure platform, the lower mold slots both sides are respectively equipped with Pneumatic compression device and plug is stifled
As a preferred embodiment, when the upper pressure platform declines, the upper pressure platform is added by described
Hydraulic plunger is realized to be declined along the guide rail.
As a preferred embodiment, when the upper pressure platform rises, the upper pressure platform passes through two institutes
State lifting piston and realize and rise along the guide rail.
As a preferred embodiment, the guide rail is V-type rail.
As a preferred embodiment, the Pneumatic compression device and the stifled sealing device of the plug can be in the lower moulds
Move in the horizontal direction groove both sides.
As a preferred embodiment, the upper mold channel is fixed on the upper pressure platform bottom by link.
After employing above-mentioned technical proposal, the beneficial effects of the utility model are：The pipe fitting for needing to process is put into lower die
Have in groove, upper mold channel declines to be fastened to form die space with lower mold slots, Pneumatic compression device and the stifled sealing device work of plug
Pipe fitting is set to be limited to form set machining shape by compression swelling, more efficient, homogeneity of product is more preferable.In addition, three pistons are changed
Pistons are lifted for a pressure plunger and two, while four guide posts are removed, change four V-type rails into, pressure plunger is responsible for
Platform declines, and falls and is completed by its own gravity, and two lifting pistons are responsible for the rising of platform, efficiently avoid platform movement
Injustice, the operating cost of interior forcing press is relatively transformed to decline to a great extent before.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
Put, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is the overall structure diagram of forcing press in the utility model.
In figure, the upper pressure platforms of 1-；Pressure platform under 2-；3- guide rails；4- pressure plungers；5- lifts piston；6- molds
Groove；Mold slots under 7-；8- Pneumatic compression devices；The stifled sealing device of 9- plugs；10- links.
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without creative efforts
All other embodiments obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of interior forcing press, including arch frame, arch frame is interior to be equipped with upper pressure platform 1 and lower pressure
Platform 2, lower pressure platform 2 are fixed setting, upper pressure platform 1 can the oscilaltion in arch frame, be equipped with arch frame
Four guide rails 3, upper pressure platform 1 can be moved along four guide rails 3, and upper 1 center of top of pressure platform is connected with pressure plunger 4, adds
4 both sides of hydraulic plunger are respectively provided with a lifting piston 5, and pressure plunger 4 and lifting piston 5 are connected by oil pipe with hydraulic oil container, on
1 bottom of pressure platform is equipped with upper mold channel 6, is equipped with lower mold slots 7 in lower pressure platform 2, lower 7 both sides of mold slots, which are respectively equipped with, to be filled
Gas pressue device 8 and the stifled sealing device 9 of plug, when upper pressure platform 1 declines, upper pressure platform 1 realizes edge by pressure plunger 4
Guide rail 3 declines, and when upper pressure platform 1 rises, upper pressure platform 1 is realized along guide rail 3 by two lifting pistons 5 to be risen, and is led
Rail 3 is V-type rail, and Pneumatic compression device 8 and the stifled sealing device 9 of plug can move in the horizontal direction in lower 7 both sides of mold slots, upper mold
Tool groove 6 is fixed on upper 1 bottom of pressure platform by link 10.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on, should be included in the utility model
