Description
Technical field
The invention belongs to extruder appts technical fields, and in particular to a kind of extruding axis quick-replaceable and locking device.
Background technique
Squeezing axis is extruder transmitting extruding force and the tool for directly acting on blank forming, is generally mounted to dynamic Liang Qianduan
It is internal.When extruder works, the forming accuracy that axis will directly affect extruded product with the concentricity of extruding center is squeezed, therefore must
Must guarantee squeeze axial end can securely lock onto the axle bed surface in dynamic beam, avoid in extrusion process squeeze axis shaking with
It is eccentric.When squeezing different size product, corresponding extruding axis is needed replacing, due to squeezing work of the axis by axial lock clamp force
With time-consuming and laborious, inefficiency when leading to artificial disassembling, assembling and replacing.
General extruding axis more changing device generallys use following two structure type: first is that using dynamic beam front end face flange pressure
Lid cooperates with axis gland helicoid is squeezed, and the locking and release for squeezing axis, this knot are realized by manual rotation's extruding axis gland
Configuration formula increases the workload of operative employee, consumes manpower；Second is that driving wedge block using two-way cylinder, locking is overcome
After pushing dynamic extruding axis gland movement, disassembling, assembling and replacing squeezes axis, and this structure type is complicated, and due to using wedge block drive
Dynamic, capacity usage ratio is not high.
Summary of the invention
The purpose of the invention is to effectively shorten the operating time for squeezing axis replacement, mitigate artificial labor intensity,
Improve the utilization rate of extruder appts.
The technical solution used to solve the technical problems of the present invention is that:
A kind of extruding axis quick-replaceable and locking device, including flange gland, squeeze axis, squeeze axis gland and dynamic beam,
The flange gland is connect by being cased with the screw of screw spring with dynamic beam, and the inner face of flange gland is in screw spring
Along axial compression in the outer end face for squeezing axis gland under the action of spring force, will be squeezed by squeezing the inner face of axis gland at this time
The surface of axle bed of the shaft locking inside dynamic beam front end；It squeezes and is evenly distributed in several counterbores on the inner face of axis gland, each
A mandril is fitted in counterbore, one end that the mandril is plugged in the counterbore is arranged with push rod spring, is squeezing shaft locking
When, push rod spring is in compressive state, and the end face of mandril is pressed in the surface of axle bed；

The inner face of axis gland pushes away the end face for squeezing axis under the active force of push rod spring, realizes the release for squeezing axis.
Motor is installed at the top of the dynamic beam, when extruding axis is in releasing orientation, the motor rotates forward operation, passes through
Transmission mechanism driving squeezes axis gland and rotates, and the opening alignment for squeezing axis gland is made to squeeze the shaft end of axis, can will be in pine at this time
The extruding axis of open state is pulled out along axial, the disassembly for completing to squeeze axis；After replacement squeezes axis, is resetted and squeezed by motor reversal operation
Last item gland, and by the plunger shaft release of one-way cylinder, axis, which is squeezed, under the action of screw spring lock onto axle bed again
End face.
The transmission mechanism includes gear sprocket wheel, chain and sprocket wheel, and the sprocket wheel is set on the output shaft of motor, sprocket wheel
By chain drive gear sprocket wheel, and drives and squeeze the rotation of axis gland.
It is evenly equipped with several screw holes on the flange gland, a screw, the screw are mounted in each screw hole
On be arranged with spring pad and screw spring.
The screw hole and the one-way cylinder circumferencial direction on the outer end face of flange gland alternate setting.
The device can be set to being screwed into depth and adjusting extruding axis for screw between flange gland and dynamic beam by controlling
The size of coupling mechanism force.
The first copper sheathing is installed between the extruding axis gland and flange gland.
The second copper sheathing is installed between the extruding axis gland and dynamic beam.
A kind of extruding axis quick-replaceable and locking method, first by flange gland by being cased with the screw of screw spring and dynamic
Beam connection, the inner face of flange gland under the action of screw spring along axial compression in squeeze axis gland outer end face, at this time
Inner face by squeezing axis gland will squeeze shaft locking in the surface of axle bed in dynamic beam, and the size of coupling mechanism force can be by changing spiral shell
Nail is screwed into the depth adjustment of dynamic beam；The counterbore mandril for being cased with push rod spring being plugged in simultaneously on the inner face for squeezing axis gland
In, when squeezing shaft locking, push rod spring is in compressive state, and the end face of mandril is pressed in the surface of axle bed；
When then pressurizeing to the one-way cylinder being installed on flange gland, the piston rod of one-way cylinder overcomes screw spring
The inner face of flange gland is pushed away the outer end face for squeezing axis gland by active force, while squeezing the inner face of axis gland in mandril bullet
The end face for squeezing axis is pushed away under the active force of spring, realizes the release for squeezing axis；The front top of dynamic beam is equipped with motor, passes through biography
Motivation structure drives extruding axis gland to rotate, and makes the shaft end for the opening alignment extruding axis for squeezing axis gland, can will be in unclamp at this time
The extruding axis of state is pulled out along axial, the disassembly for completing to squeeze axis；After replacement squeezes axis, axis pressure is squeezed by motor spinning reduction
Lid, and by one-way cylinder release, the end face that axis lock onto axle bed again is squeezed under the action of screw spring.
Extruding axis replacement in the present invention is with the beneficial effect of locking device: the device can by control flange gland and
Dynamic beam attachment screw is screwed into depth to realize the adjusting for squeezing shaft locking power size；It squeezes the locking of axis and unclamps and only pass through list
