Abstract
The utility model discloses a double-action hydraulic machine which not only can press edges, but also can carry out calendering. The utility model is particularly suitable for processing non-ferrous metal barrels and basin-shaped parts. A four-beam type double-action hydraulic machine is composed of a three-beam type hydraulic machine additionally provided with an edge pressing beam. The automation of workpiece calendering process is realized by electric and hydraulic control and an ejector with a particularly simple structure.
Description
The utility model relates to two action hydraulic machines that a kind of existing flanging beam has the calendering beam again, is particularly suitable for being processed with non-ferrous metal tube, basin shape part.
Existing middle-size and small-size hydraulic machine mainly is made of column, base (sill), calendering beam (sliding beam) and entablature three beam types, and the four-column hydraulic press that adopts generally is this form at present.When the general tube of compacting, basin shape part, a cover flanging device must added on the lathe or on the mould, increase very big difficulty to mould design and manufacturing, and all necessary additional design one cover flanging device of every mold of different size, very big waste can be caused.Concerning former lathe, increase flange fixing installation, also to increase hydraulic power unit, not only lose more than gain, and be subjected to the restriction of former lathe again, influence the utilization rate of hydraulic press, its Lifting Device of existing hydraulic press all is provided with a liftout oil cylinder specially, the liftout by the cylinder motion of hydraulic valve control liftout, its structure is very complicated, produces asynergia sometimes.
The purpose of this utility model provides a kind of improved pair of action hydraulic press, it can make general tube, basin shape part not need to increase any auxiliary flange fixing installation, desirable flanging, calendering, flanging backhaul, each procedure of liftout finished automatically on a hydraulic press.
The utility model is achieved in that increases a flanging crossbeam in the middle of three beams, constitute the two action hydraulic presses of four beam types.Power drive flanging beam by the flanging cylinder is realized flanging.After pressure-pad-force reached certain pressure, notice calendering beam was worked under the effect of calendering oil cylinder, realizes calendering.Behind the calendaring molding, reach certain pressure, notify calendering backhaul and flanging backhaul, during the flanging backhaul,, drive the two screw rods that is installed on the flanging beam and rise together, make connection horizontal stripe, ejector beam move together, realize automatic material jacking by the action that the backhaul of flanging beam is risen.
Introduce an embodiment of the present utility model below in conjunction with accompanying drawing:
Fig. 1 is a kind of hydraulic press schematic diagram that the utility model device is housed.
Fig. 2 is a kind of flanging of the present utility model---Lifting Device figure.
A kind of four beam type hydraulic presses are made up of base (1), flanging oil cylinder (2), flanging beam (3), calendering beam (4), entablature (5), column (6), interlock horizontal stripe (7), screw rod (8), ejector beam (9) etc.The simple especially flanging beam (3) of structure is installed between calendering beam (4) and the base (1), behind cycle button of connection, flanging beam (3) moves under the effect of flanging oil cylinder (2), push down the part woolen cloth that is placed on the base (1), after flanging reached certain pressure, notice calendering beam (4) moved downward calendering, behind the calendaring molding, the backhaul that moves upward respectively of notice calendering beam, flanging beam, once circulation finishes.
Automatic material jacking device with flanging beam (3) disjunctor utilizes the rising backhaul action of flanging beam (3), drives two screw rods (8), and interlock horizontal stripe (7) makes ejector beam (9) liftout that moves upward.
Claims (1)
- A kind of hydraulic press of being made up of column, base, calendering beam, entablature etc. is characterized in that also being equipped with a flanging--Lifting Device, and this device has the kidney slot that blank holder can be installed or the flanging beam of T-slot by one, drives the flanging beam and moves up and down along column.The flanging oil cylinder that its piston rod and flanging beam fix and be connected, the compositions such as ejector beam that are connected with the flanging beam by screw rod and interlock horizontal stripe, flanging oil cylinder cylindrical shell fixes with lathe bed and is connected, and drives the flanging beam that has blank holder when flanging oil cylinder piston bar moves downward and carries out flanging; When stretching finished the oil cylinder backhaul, the flanging beam made the ejector beam liftout of interlock.
