Abstract

The utility model relates to a flying shear edge dismantling device. The device is characterized in that the device comprises push-off hydraulic cylinders and axial oil ducts arranged in the rotary center of a drum; the push-off hydraulic cylinders are arranged on the back of the shear edge push-off directions; and the axial oil ducts are communicated with radial oil ducts of the push-off hydraulic cylinders. The device has the following advantages: the shear edges can be accurately and timely changed; the shear edge change time can be shortened; and the operation efficiency of shear edge change can be improved.

Description

A kind of flying shear blade provision for disengagement

Technical field

The utility model relates to a kind of dismounting servicing unit, is specifically related to a kind of flying shear blade provision for disengagement.

Background technology

In the hot-strip production process, flying shearing machine are visual plants of intermediate blank cutting head cutting tail.The mechanism form of pressing flying shearing machine is different, and its cutting edge installation form also has nothing in common with each other, and wherein the fixing eight cover locking cylinders that lean on of each cutting edge of rotary drum flying shear are realized.The effect of the disk spring in the locking cylinder can make clamping block produce pressure in the cutting edge side and realize that cutting edge cutting locking on the drum.When needs are pulled down cutting edge, in locking cylinder, feed pressure oil, make disk spring produce compression, make the side of clamping block side disengaging cutting edge and remove locking.Because cutting edge is fixed on for a long time and cuts in the groove, though removed locking, the phenomenon of difficulty often appears taking out in cutting edge, thereby the time of cutting edge is changed in influence.

Summary of the invention

For overcoming the deficiency of prior art, the purpose of the utility model provides a kind of flying shear blade provision for disengagement, and this device can effectively solve the problem of cutting edge taking-up difficulty in the prior art, enhances productivity.

For realizing above-mentioned purpose, the utility model is realized through following technical scheme:

A kind of flying shear blade provision for disengagement is characterized in that, comprises the axial oil duct of releasing hydraulic cylinder, being arranged at the rotary drum centre of gyration, releases hydraulic cylinder and is arranged at the back side that cutting edge is released direction, and axially oil duct is connected with the radial direction oil of releasing hydraulic cylinder.

The utility model has the advantages that: can change cutting edge accurately, timely, shorten the time of changing cutting edge, improve the operating efficiency of changing cutting edge.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: 1-cutting edge 2-bore hole 3-releases the axial oil duct of hydraulic cylinder 4-clamping block 5-locking hydraulic cylinder 6-rotary drum 7-

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:

See Fig. 1, a kind of flying shear blade provision for disengagement comprises the axial oil duct 7 of releasing hydraulic cylinder 3, being arranged at rotary drum 6 centres of gyration, releases hydraulic cylinder 3 and is arranged at the back side that cutting edge 1 is released direction, and axially oil duct 7 is connected with the radial direction oil of releasing hydraulic cylinder 3.

Flying shear drives main gear reducer by a direct current generator through gear coupling; Receive on the following rotary drum of flying shear body through gear coupling (or connecing axle) again; Make it to have the relative gyration of constant speed up and down between the rotary drum by the synchromesh gear that is contained in the rotary drum both sides, and finally accomplish crop, the back-end crop work of intermediate blank through crop, back-end crop cutting edge.

Under the situation that does not change former drum structure,, it is released hydraulic cylinder 3 pack into wherein at the bore hole 2 of corresponding vertical and two installations of axial location processing of cutting edge that each rotary drum is installed 1.On rotary drum 6 centres of gyration, process its axial oil duct 7 again, and link to each other, form an oil supply loop with the radial direction oil of leading to release hydraulic cylinder 3.

Rotary drum respectively is equipped with crop, back-end crop cutting edge up and down, and 2 release hydraulic cylinders 3 are equipped with in every group of cutting edge bottom surface.When needs are pulled down cutting edge, in locking hydraulic cylinder 5, feed pressure oil, make disk spring produce compression, make the side of clamping block 4 sides disengaging cutting edge 1 and remove locking.Then in releasing hydraulic cylinder 3, feed pressure oil, make disk spring produce compression, cutting edge 1 is directly ejected.

Claims (1)

1. a flying shear blade provision for disengagement is characterized in that, comprises the axial oil duct of releasing hydraulic cylinder, being arranged at the rotary drum centre of gyration, releases hydraulic cylinder and is arranged at the back side that cutting edge is released direction, and axially oil duct is connected with the radial direction oil of releasing hydraulic cylinder.
