Abstract
A kind of hydraulic drive type banding machine cutting disc locking device, including locking main body axis, push-tight block and push-tight piston, plunger shaft and pushing hole are provided in locking main body axis, push-tight piston is provided in plunger shaft, push-tight piston stretches out plunger shaft, and push-tight block is arranged in pushing hole and is fixed on one end that push-tight piston stretches out plunger shaft.The front end of locking main body axis is fixedly connected with banding machine main shaft, and the plunger shaft of locking main body axis is connect by pipeline with air-driven hydraulic pump.Hydraulic oil is injected plunger shaft by air-driven hydraulic pump, and thrust is formed after oiling, and thrust is by acting on push-tight piston, while retracting spring is stretched, and push-tight piston driving push-tight block is mobile, compresses the cutting disc on banding machine main shaft；After pressure release, push-tight piston is reset to reset condition by the pulling force of spring by retracting spring.The device is easy to operate, can be with automatic compensation, and stability is good, reliable lock, and consistent always to cutting disc pressing force, the relative position between cutting disc is more stable.
Description
Technical field
The present invention relates to a kind of on hydraulic drive type banding machine device that cutting disc locks, belongs to cutting disc locking skill
Art field.
Background technique
Banding machine be by the longitudinal sectional equipment at several required specification tapes of sheet metal strip, including upper rotor and lower rotor, on
Rotor and lower rotor are mounted on the rack, and upper rotor can finely tune up and down, with adapt to shearing different-thickness plate, upper rotor and
Lower rotor respectively with a power output axis connection.Disc scissors in multiple groups are installed on upper rotor, are installed under multiple groups on lower rotor
Disc scissors, the setting of the distance between each group disc scissors width according to needed for the plate after slitting.On one group disc scissors and
One group of lower disc scissors is corresponding.The sideshake of upper disc scissors and lower disc scissors is adjusted according to the metal blank thickness of slitting.It opens
Plate after volume enters between upper rotor and upper rotor, moves ahead under the two drive, while corresponding on upper rotor and upper rotor
Slitting is cut off under the shearing of disc scissors.
In use, the sideshake of upper disc scissors and lower disc scissors can change, and cause metal blank slitting
Side band afterwards is jagged, influences quality.
There are two types of the modes to solve the above problems at present：
1：It is screwed on mechanical round nut by screw thread, is pounded tightly with round nut spanner by sledgehammer, pretightning force is not guaranteed, and
It operates very inconvenient.
2：It is screwed on mechanical round nut by screw thread, hydraulic nut, hydraulic spiral shell is added between mechanical nut and cutting disc
Mother is also to be tightened by manual wrench, inconvenient for operation, is unable to automatic compensation, stability is bad.
Summary of the invention
The present invention existing banding machine cutting disc locking technology there are aiming at the problem that, provide a kind of structure is simple, locking can
The hydraulic drive type banding machine cutting disc locking device leaned on.
Hydraulic drive type banding machine cutting disc locking device of the invention, using following technical scheme：
The device, including locking main body axis, push-tight block and push-tight piston, lock in main body axis and are provided with plunger shaft and passage
Hole, push-tight piston are arranged in plunger shaft, and push-tight block is arranged in pushing hole and connect with push-tight piston.
Retracting spring is provided between the push-tight piston and plunger shaft, it is living that the both ends of retracting spring are separately fixed at push-tight
On plug and plunger shaft.
Plunger shaft outer end is connected with rotary joint in the locking main body axis.
Excessive set is provided on the push-tight block.
The front end of locking main body axis is fixedly connected with banding machine main shaft, and the plunger shaft of locking main body axis is by pipeline and pneumatically
Hydraulic pump connection.Hydraulic oil is injected plunger shaft by air-driven hydraulic pump, and thrust is formed after oiling, and thrust is living by acting on push-tight
Plug, while retracting spring is stretched, push-tight piston driving push-tight block is mobile, compresses the cutting disc on banding machine main shaft；After pressure release,
Push-tight piston is reset to reset condition by the pulling force of spring by retracting spring.
The present invention is plugged pipeline by quick-release connector, can be operated by knob, easy to operate；It can mend automatically
Pressure, stability is good, and consistent always to cutting disc pressing force, the relative position between cutting disc is more stable, the shearing to plate
Better quality.Have the characteristics that structure is simple, reliable lock.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of hydraulic drive type banding machine cutting disc locking device of the present invention.
Wherein：1. excessively set, 2. push-tight blocks, 3. push-tight pistons, 4. rotary joints, 5. air-driven hydraulic pumps, 6. pipelines, 7. times
Journey spring, 8. locking main body axis, 9. pushing holes, 10. spacers, 11. cutting dives, 12. banding machine main shafts.
Specific embodiment
As shown in Figure 1, hydraulic drive type banding machine cutting disc locking device of the invention, including locking main body axis 8, excessively
Set 1, push-tight block 2 and push-tight piston 3.Plunger shaft and pushing hole 9 are provided in locking main body axis 8.It is provided with and pushes away in plunger shaft
Tight piston 3, push-tight piston 3 stretch out plunger shaft.Sealing ring, push-tight piston 3 and piston are provided between push-tight piston 3 and plunger shaft
Retracting spring 7 is provided between chamber, the both ends of retracting spring 7 are separately fixed in push-tight piston 3 and plunger shaft.Push-tight block 2 is set
It sets in the pushing hole 12 on locking main body axis 8, and plunger shaft one (is stretched out in the front end for being bolted on push-tight piston 3
End), pushing hole 9 plays the position-limiting action when movement of push-tight block 2.
The front end of locking main body axis 8 is fixedly connected by bolt with banding machine main shaft 12, and the rear end for locking main body axis 8 is (living
Plug chamber rear portion) it is connected with rotary joint 4, rotary joint 4 is connect by pipeline 6 with air-driven hydraulic pump 5.
Hydraulic oil is injected plunger shaft by pipeline 6 and rotary joint 4 by air-driven hydraulic pump 5, and thrust, thrust are formed after oiling
By acting on push-tight piston 3, while retracting spring 7 is stretched, and push-tight piston 3 drives push-tight block 2 and excessively set 1 is mobile, leads to
Cross the cutting disc 9 on the compression banding machine main shaft 12 of spacer 10.
After pressure release, hydraulic oil pressure is returned by air-driven hydraulic pump 5 by retracting spring 7.System meeting automatic compensation keeps thrust not
Become, push-tight piston 3 is reset to reset condition by the pulling force of spring 7 after unloading.
Push-tight Li≤400KN of locking device of the invention, maximum working pressure (MWP) 150MPa, pressure facilitate adjustment.Push-tight
Device spindle nose can hold radial load power≤450KN, and 2 moving distance of push-tight block (push-tight stroke) is 20mm.
