Description
Technical field
The invention belongs to technical field of high-pressure lock mold equipment, be specifically related to a kind of Mode-locking oil cylinder.
Background technology
Mode-locking oil cylinder, is a kind of mechanism providing high-voltage lock mould of vertical two panel extrusion shapers.As shown in Figure 1, when mould 6 is carried out high-voltage lock mould, its dynamic beam 1 and determine beam 2 clamping in mould 6 both sides, one end of pull bar 3 is run through and is determined together with beam 2 locks with Mode-locking oil cylinder 5, the other end of pull bar 3 runs through dynamic beam 1 and is threaded togather with cohesion nut 4, in Mode-locking oil cylinder 5, once inject the one end that can make pull bar 3 after hydraulic oil to determining the outer side shifting of beam 2, and then pull dynamic beam 1 close to determining beam 2, reach tightly to pin the purpose of mould 6.
As shown in Figure 2, Mode-locking oil cylinder 5, including be fixedly connected on the drive end bearing bracket 51 determined on beam 2 be connected by screw with described drive end bearing bracket 51 together with cylinder barrel 52, the piston rod 53 being sleeved on pull bar 3, connect the mother nut 55 that piston 54 on the piston rod is threaded togather and the connection cover 56 being connected to cylinder barrel 52 tail end with pull bar 3.
As it is shown on figure 3, in existing Mode-locking oil cylinder 5, be connected by screw is fixing between mother nut 55 with piston 54, mother nut 55 is plane (B in Fig. 3 is partially shown) with the contact surface of piston 54.
As illustrated in fig. 1 and 2, at dynamic beam 1 with during determining beam 2 extrusion die 6, determine beam 2 stress and can produce the slight curves in direction shown in dotted line in figure, determine beam 2 stress deformation drive drive end bearing bracket 51, cylinder barrel 52 to be deflected together, but pull bar 3 is will not to bend with determining beam 2, so that can produce certain drift angle between pull bar 3 and cylinder barrel 52.
It is connected owing to being that plane is fixing between mother nut 55 with piston 54, mother nut 55 is integrally fixed at again on pull bar 3, then piston 54 will not deflect with determining beam 2 as cylinder barrel 52, so between piston 54 and cylinder barrel 52, shape is at a certain angle, the generation of this angle is by breakseal generation oil leakage phenomenon.More seriously, due to the gap between piston 54 and cylinder barrel 52 the least (typically smaller than 1 millimeter), not to the gap between mother nut 55 and cylinder barrel 52 so big (generally between 2-5 millimeter), when determining beam 2 and deforming bigger, piston 54 is by direct scratch cylinder barrel 52.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of sealing effectiveness and more preferably and be not easy the Mode-locking oil cylinder being scraped off.
For achieving the above object, the used technical scheme of the present invention is as follows:
A kind of Mode-locking oil cylinder, including cylinder barrel and be positioned at the piston within cylinder barrel and mother nut, between piston with mother nut, sphere is connected.
Further, the lower surface of described piston is the concave spherical surface that indent is formed, and the upper surface of described mother nut is the convex spherical that evagination is formed；Between described piston and mother nut, sphere is connected, and the most described concave spherical surface contacts connection with described convex spherical.
Further, the lower surface of described piston is the convex spherical that evagination is formed, and the upper surface of described mother nut is the concave spherical surface that indent is formed；Between described piston and mother nut, sphere is connected, and the most described concave spherical surface contacts connection with described convex spherical.
Further, the internal diameter of described concave spherical surface and described convex spherical is outer through identical.
Further, the gap between described mother nut and described cylinder barrel is more than or equal to 1.5 millimeters.
The present invention has changed the attachment structure between piston and mother nut into spherical surface connecting structure, can rotate against between piston and mother nut, piston is no longer by the fixing constraint of mother nut, at cylinder barrel with determining in beam deflection, piston can be followed cylinder barrel and be deflected together, and then ensure that the excellent sealing effect between piston and cylinder barrel, and piston scratch cylinder barrel can be prevented effectively from.

Detailed description of the invention
Describing the present invention in detail below in conjunction with accompanying drawing and specific implementation method, the exemplary embodiment and description in the present invention are used for explaining the present invention, but not as a limitation of the invention.
Embodiment 1:
As shown in Figure 2, present embodiment discloses a kind of Mode-locking oil cylinder, it mainly includes the cylinder barrel 52 together with being fixedly connected on the drive end bearing bracket 51 determined on beam 2 is connected by screw with described drive end bearing bracket 51, the piston rod 53 being sleeved on pull bar 3, connects the mother nut 55 that piston 54 on the piston rod is threaded togather with pull bar 3 and the connection cover 56 being connected to cylinder barrel 52 tail end, and piston 54 and mother nut 55 are all located in cylinder barrel 52.
As shown in Figure 4, the lower surface of piston 54 is the concave spherical surface that indent is formed, the upper surface of described mother nut 55 is the convex spherical that evagination is formed, the concave spherical surface of piston 54 contacts connection with the convex spherical of mother nut 55, is i.e. that between piston 54 with mother nut 55, sphere is connected (B in Fig. 4 is partially shown).Certainly, so that piston 54 is more preferable with mother nut 55 fiting effect, the internal diameter of described concave spherical surface is outer through identical with described convex spherical.
Although mother nut 55 is enough big with the spacing of described cylinder barrel 52 in existing structure, in order to prevent mother nut 55 scratch cylinder barrel 52, the gap between the further clear and definite mother nut 55 of the present embodiment and cylinder barrel 52 is more than or equal to 1.5 millimeters.
It should be noted that sphere is connected between piston 54 with mother nut 55, concrete it may also is that
The lower surface of piston 54 changes into the convex spherical that evagination is formed, and the upper surface of mother nut 55 changes the concave spherical surface that indent is formed into, and the convex spherical of piston 54 contacts connection with the concave spherical surface of mother nut 55.Its principle is identical with Fig. 4 structure, is only that the two concavo-convex sphere contacted with each other is exchanged.
It should be noted that the present embodiment includes but not limited to that the internal diameter of concave spherical surface and the outer of described convex spherical, through identical situation, also include the internal diameter situation more than the external diameter of convex spherical of concave spherical surface, these are all protection scope of the present invention.
Using the present embodiment structure, the piston of Mode-locking oil cylinder will not deflect with cylinder barrel as being fastenedly connected, it is to avoid serious leak or coup injury phenomenon occurs in Mode-locking oil cylinder, improves the service life of the present embodiment.
The technical scheme provided the embodiment of the present invention above is described in detail, principle and the embodiment of the embodiment of the present invention are set forth by specific case used herein, and the explanation of above example is only applicable to help to understand the principle of the embodiment of the present invention；Simultaneously for one of ordinary skill in the art, according to the embodiment of the present invention, all will change in detailed description of the invention and range of application, in sum, this specification content should not be construed as limitation of the present invention.
