Abstract
The present invention is a kind of break, belong to the break on a kind of aluminium extrusion production line, particularly a kind of high pressure oil or pressurized air of adopting is braked as brake power, the break that belleville spring resets, solve the inaccurate problem of distractor stop position, which comprises at least cylinder body (1), piston (2), support plate (5), bearing (6), locking block (8), brake block (9).During work, hydraulic oil or pressurized air enter cylinder body (1) by the hole (10) on cylinder body (1), promote piston (2) and are pushed on brake lining by brake block (9), carry out fast braking.The present invention makes tractor stop at the position of technological requirement fast, accurately, safely, and its automaticity is high, and braking is reliable, and operation is convenient.
Description
Technical field
The invention belongs to the break on a kind of aluminium extrusion production line, particularly a kind of high pressure oil or pressurized air of adopting is braked as brake power, the break that belleville spring resets.
Background technique
Aluminium extruding machine in process of production, in order to eliminate the uneven of mould mouth metal flow, is generally provided with tractor.Tractor operationally hauling speed and extrusion speed matches, and in order to meet collapse phase, the return speed of tractor even reaches 3m/s, and such tractor just needs the position stopping at technological requirement fast, accurately, safely.
Current technology is the signal provided by rotating coder or coded scale according to technological requirement, adopts the start and stop of Frequency Converter Control traction electric machine, and then controls startup and the stopping of tractor.Owing to there is effect of inertia, send rear haulage machine in stop signal can slide a distance toward contact, cause stop position inaccurate, the faster error of speed is larger, the method of pre-decelerating is adopted, even the method for sectional deceleration in advance can be adopted in order to reduce error.Although this method can reduce error, can beat be taken, nor error can be eliminated completely.
Summary of the invention
The object of this invention is to provide on a kind of aluminium extrusion production line makes tractor stop at the braking device of technological requirement position fast, accurately, safely.
Technological scheme of the present invention is achieved in that a kind of break, it is characterized in that: which comprises at least cylinder body, piston, support plate, bearing, locking block, brake block, cylinder body is fixedly connected with support plate, piston is had in cylinder body, piston right-hand member is fitted in guide sleeve, piston cylinder is formed with cylinder body and support plate, guide sleeve is fixedly connected with support plate, belleville spring is in the cavity surrounded by piston and support plate, locking block is fixedly connected with pistons end, brake block and locking block glued joint, and bearing is fixedly connected with support plate, and cylinder body passing hole connects hydraulic pressure or pneumatic system.
There is seam described support plate and locking block contacting point, and bearing is fixedly connected with tractor, and bearing has seam.
The roller-way braking surface of the corresponding tractor of described brake block is that 2mm is to piston stroke with the distance of braking surface.
Feature of the present invention is: during braking, hydraulic pressure or pneumatic system control high pressure oil or pressurized air enters from the hole cylinder body, under high pressure oil or compressed-air actuated effect, the resistance of piston overpowers belleville spring is protruding, thus promotion brake block is close to roller-way braking surface, reach the object of braking, tractor is fixed on the position of technological requirement; When tractor runs, high pressure oil or pressurized air flow out from the hole cylinder body, and piston shrinks under spring force, and brake block departs from roller-way braking surface, brake off.
The invention has the beneficial effects as follows: by hydraulic pressure or pneumatic system, piston is ejected, make brake block be close to rapidly braking surface and brake, thus reduce stopping distance, realize fast braking.

Fig. 2 is the left view of embodiment 1;
Fig. 3 is the P direction view of embodiment 1.
In figure: 1, cylinder body; 2, piston; 3, Sealing; 4, belleville spring; 5, support plate; 6, bearing; 7, guide sleeve; 8, locking block; 9, brake block; 10, hole.
Embodiment
Embodiment 1
As Fig. 1, 2, shown in 3, a kind of break, it is characterized in that: which comprises at least cylinder body 1, piston 2, support plate 5, bearing 6, locking block 8, brake block 9, cylinder body 1 is fixedly connected with support plate 5, piston 2 is had in cylinder body 1, piston 2 right-hand member is fitted in guide sleeve 7, piston cylinder is formed with cylinder body 1 and support plate 5, guide sleeve 7 is fixedly connected with support plate 5, belleville spring 4 is in the cavity surrounded by piston 2 and support plate 5, locking block 8 is connected with piston 2 end winding support, brake block 9 and locking block 8 glued joint, bearing 6 is fixedly connected with support plate 5, cylinder body 1 passing hole 10 connects hydraulic pressure or pneumatic system.
Embodiment 2
Substantially the same manner as Example 1, institute's difference is that support plate 5 and locking block 8 contacting point are provided with seam, as the guiding of locking block 8 during brake operation.Bearing 6 is welded on the correct position of tractor, is provided with seam, the shearing stress produced when overcoming braking.The roller-way braking surface of the corresponding tractor of brake block 9 is 2mm with the distance of braking surface.There is Sealing 3 between piston 2 and cylinder body 1, prevent high pressure oil or pressurized air from revealing.
During braking, hydraulic pressure or pneumatic system control high pressure oil or pressurized air enters from hole 10, and under high pressure oil or compressed-air actuated effect, the resistance that piston 2 overcomes belleville spring 4 is protruding, thus promotion brake block 9 is close to roller-way braking surface, reach the object of braking, tractor is fixed on the position of technological requirement, when tractor runs, high pressure oil or pressurized air flow out from hole 10, piston 2 shrinks under the active force of belleville spring 4, and brake block 9 departs from roller-way braking surface, brake off.
The parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
