Abstract
The utility model relates to a split type piston for rolling mill swing jar installs a piston respectively at the both ends of the rack with the meshing of rolling mill swing jar, and this piston be split type structure, is divided into preceding piston and back piston that coaxial make -up was adorned admittedly, and the shape of preceding piston and the side end face orthographic projection of back piston is the echelonment, and reversion that preceding piston, back piston make -up inclined inclines equal coaxial system has the boss. The utility model provides a split type piston for rolling mill swing jar, the fastening by bolted connection is cut with back piston two parts to the piston before becoming the piston split, guaranteed the basis of leakproofness on, make the dismouting lighter, the seal section forms the echelonment, both sides are high promptly, middle hanging down, the sealing performance of piston is further guaranteed at effective isolation seal installation position more.
Description
Technical field
This utility model belongs to milling train auxiliary apparatus field, particularly a kind of Split piston for milling train oscillating cylinder.
Background technology
Pressure roller before rolling machine, after machine swings and is realized by oscillating cylinder band dynamic pressure roller rotating shaft, concrete structure is shown in Fig. 1, two oil cylinders on the same straight line of oscillating cylinder share a toothed rack 3, and a piston 2 is respectively with at the two ends of tooth bar 3, and two toothed rack 3 engage with the gear in intermediate 5.Pressure oil is entered by two hydraulic fluid ports 1 tiltedly faced toward, and promotes two pistons 2 and tooth bar 3 move toward one another of the inside, and the gear in intermediate 5 with rotation, is realized the swing of pressure roller due to engagement by key with dynamic pressure roller rotating shaft.If pressure oil enters from other two hydraulic fluid port 1, it may be achieved swing commutation.Due to the special construction of oscillating cylinder, cause maintenance difficult, especially when piston seal damages, from intermediate 5, cylinder barrel 4 is screwed out, expose piston 2 and tooth bar 3；Owing to piston 2 is overall, remove and installation combination sealing is very difficult, often can damage sealing member, cause the loss of manpower and material resources.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, it is proposed to a kind of Split piston for milling train oscillating cylinder being prone to split and keep excellent sealing degree.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of Split piston for milling train oscillating cylinder, it is respectively mounted a piston at the two ends of the tooth bar engaged with milling train oscillating cylinder, this piston is split-type structural, it is divided into secondary piston and back piston that coaxial make-up is fixedly mounted with, being shaped as of the side end face orthographic projection of secondary piston and back piston is stepped, secondary piston, back piston make-up side reverse side be all coaxially shaped with boss.
And, described secondary piston and back piston are fixedly mounted with by multiple homoaxial bolts.
Advantage of the present utility model and having the advantages that
The Split piston for milling train oscillating cylinder that this utility model provides, piston is split into secondary piston and back piston two parts are cut and connected fastening by bolt, ensure that on the basis of sealing, make dismounting lighter, seal section is formed stepped, and namely both sides are high, middle low, more effective isolating seal installation position, is further ensured that the sealing property of piston.
Accompanying drawing explanation
Fig. 1 is the structural representation of milling train oscillating cylinder；
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Implementing to be further described to this utility model below in conjunction with accompanying drawing, following example are illustrative, are not determinate, it is impossible to limit protection domain of the present utility model with this.
A kind of Split piston for milling train oscillating cylinder, it is respectively mounted a piston at the two ends of the tooth bar engaged with milling train oscillating cylinder, this piston is split-type structural, it is divided into make-up is fixedly mounted with by multiple homoaxial bolts 6 are fixing secondary piston 7 and back piston 8, being shaped as of the side end face orthographic projection of secondary piston and back piston is stepped, secondary piston, back piston make-up side reverse side be all coaxially shaped with boss 9.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope without departing from this utility model and claims, various replacements, to change and modifications be all possible, therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
