Description

A kind of Assel milling train quick-opening device
Technical field
The utility model relates to a kind of roll quick-opening devices of Assel milling train for producing seamless steel pipe, especially volume Quick-opening device small, response is fast.
Background technique
Currently, when known Assel milling train production thin-wall seamless steel pipe, it may appear that outer diameter burst in tail portion becomes larger, at triangle Horn mouth is commonly called as " tail triangle ", is easy to appear and rolls card, causes to shut down, while influencing tube quality.It needs to be equipped in normal production Roller gap regulating device, separates roll quickly, reduces tail triangle and generates.But conventional quick-opening device uses piston oil Pipe, volume is big, weight weight, milling train principal space is occupied, if original milling train does not have quick-opening device that can not install additional.Dress is generally opened fastly The fluid power system of outfit is set because volume is big, causes response to be delayed, influences to open effect fastly.
Utility model content
In order to overcome the bulky deficiency of existing quick-opening device, the utility model provides a kind of quick-opening device, this is opened fastly Device can not only be such that roll quickly adjusts, and small in size, light-weight, and mechanism is compact, can change on original Assel milling train Make installation.
The technical solution adopted in the utility model is thus: a kind of Assel milling train quick-opening device, including rolls for installing The roller base (2) of roller (1) is provided with baltimore groove far from roll (1) on the roller base (2) on one side, pacifies in the baltimore groove Equipped with hydraulic ram cylinders (3);
The hydraulic control valve of control hydraulic ram cylinders (3) operating, the hydraulic control are provided on the hydraulic ram cylinders (3) Valve processed includes the fluid pressure line (6) that one end is connected to the hydraulic ram cylinders (3), the other end connection of the fluid pressure line (6) To hydraulic lock (8), the hydraulic lock (8) is connected to reversal valve (9), and the reversal valve (9) is connected to hydraulic power unit (10);
It is additionally provided with the adjustable telescopic screw rod (4) being correspondingly arranged with the hydraulic ram cylinders (3), is additionally provided with and institute State the balancing cylinder (5) that roller base (2) is correspondingly arranged.
It is additionally provided with the pressure tap (7) for detecting hydraulic lock (8) pressure.
Two baltimore grooves are symmetrically arranged on the roller base (2), are provided in the baltimore groove described hydraulic Plunger case (3).
The utility model has the advantages that: during Assel mill milling, roll can be separated quickly, small in size, weight Amount is light, and mechanism is compact, and installation can be transformed on original Assel milling train;The utility model is in hydraulic drive mechanism, configuration Hydraulic lock realizes that oil cylinder position is stablized in the operation of rolling, has good practicability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1 it is roll in figure, 2 be roller base, 3 be hydraulic ram cylinders, 4 be telescopic screw rod, 5 be balancing cylinder, 6 is hydraulic tube Road, 7 be pressure tap, 8 be hydraulic lock, 9 be reversal valve, 10 be hydraulic power unit.
Specific embodiment
A kind of Assel milling train quick-opening device, it is separate on the roller base 2 to roll including the roller base 2 for installing roll 1 Roller 1 is provided with baltimore groove on one side, and hydraulic ram cylinders 3 are equipped in the baltimore groove;
The hydraulic control valve that control hydraulic ram cylinders 3 operate, the hydraulic control valve are provided in the hydraulic ram cylinders 3 The fluid pressure line 6 of the hydraulic ram cylinders 3 is connected to including one end, the other end of the fluid pressure line 6 is connected to hydraulic lock 8, The hydraulic lock 8 is connected to reversal valve 9, and the reversal valve 9 is connected to hydraulic power unit 10;
It is additionally provided with the adjustable telescopic screw rod 4 being correspondingly arranged with the hydraulic ram cylinders 3, is additionally provided with and is rolled with described The balancing cylinder 5 that roller seat 2 is correspondingly arranged.
It is additionally provided with the pressure tap 7 for detecting 8 pressure of hydraulic lock.
It is symmetrically arranged with two baltimore grooves on the roller base 2, the hydraulic column is provided in the baltimore groove Plug cylinder 3.
The working process of the utility model is as follows: Assel roll regulating mechanism by lift telescopic screw rod 4, hydraulic ram cylinders 3, Assel roller base 2 and balance hydraulic cylinder 5 form.Two baltimore grooves are processed in Assel roller base 2, are pacified in each groove Fill a super-thin hydraulic ram cylinders 3.Each hydraulic ram cylinders 3 are furnished with hydraulic control valve equipped with independent, are furnished with commutation in oil circuit Valve 9, hydraulic lock 8, when each working condition, each assembly function is as follows:
Before normal rolling, balancing cylinder 5 stretches out, and roller base 2, which is in, unclamps position, and reversal valve 9 is in right position, hydraulic ram cylinders 3 are in stretching state, adjust 4 overhang of lift telescopic screw rod, adjust 2 position of roller base, roll gap is made to be in as-rolled condition.
When starting rolling, balancing cylinder 5 is in contraction state, and guarantee opens hydraulic ram cylinders 3 fastly and adjusts telescopic screw rod 4 tightly Close combination, hydraulic ram cylinders 3 bear roll-force.5 convergent force of balancing cylinder is less than opens 3 ejecting force of hydraulic ram cylinders fastly.Hydraulic lock 8 Work opens 3 position of hydraulic ram cylinders fastly and does not change when guaranteeing roll-force variation.
When being rolled down to tail portion, reversal valve 9 switches to left position, and hydraulic lock 8 is opened, under the convergent force of balancing cylinder 5, opened fastly Hydraulic ram cylinders 3 are shunk, and 1 roll gap of roll is opened, and realize hollow billet " tail triangle " by roll host, proportioning valve work controls liquid The contraction speed of compression leg plug cylinder 3.
