Abstract
The invention relates to a mandrel flat-pressing device, comprising a supporting seat and a roller mandrel, wherein the roller mandrel is arranged on the supporting seat through a supporting bearing; a driving mechanism is fixedly connected onto the supporting seat; a nut which can slide up and down and further can be pressed on the rear end part of the roller mandrel is arranged on the supporting seat; a screw rod matched with the nut is arranged in the nut; and the driving mechanism is connected onto the screw rod through a transmission mechanism and further drives the screw rod to rotate. After the overcoming of defects in the prior art, the invention provides the flat-pressing device for the solution of mandrel droop.
Description
[technical field]
The present invention relates to a kind of printing element of set type flexible printing press,, what be specifically related to is forme mandrel, net roller core shaft pressuring flat device.
[background technology]
The printing element of existing high-grade set type flexible printing machine, net roller, forme adopt telescoping structure more, because sleeve will take out from fore side.So forme, the supporting construction of net roller core shaft mostly is a side fixed support of transmission, and a side of operation is movable supporting.After a side bearing of operation is opened, mandrel front end all can be sagging, and sagging main cause is that mandrel is overweight, long, and mandrel produces distortion, and a side of transmission supports built on the sand, and flexible distortion causes, and the size of sag of chain is according to the weight of mandrel and length and difference.Like this, when again closing the bearing of operation one side, sagging because of mandrel front end, causes bearing to close.
Existing way is: forme, the sagging very difficult solution of net roller core shaft, and sag of chain is little, how mandrel Leading end chamfer angle is increased, and increases the guiding length of bearing altogether time, though can close bearing, effort is very large, and easily by front end bearing damage; If sag of chain is larger, mostly be and use lever people for levering up, very unreasonable.
[summary of the invention]
The present invention seeks to provides a kind of sagging pressuring flat device of mandrel that solves in order to have overcome deficiency of the prior art.
In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposal:
A kind of net roller core shaft, forme mandrel pressuring flat device, it is characterized in that including bearing 1 and be located at the roller core shaft 3 on bearing by spring bearing 2, on bearing 1, be fixedly connected with driving mechanism 4, at bearing 1, be provided with and can upper and lower slip also can be pressed in the nut 5 in roller core shaft 3 rearward end, in nut 5, be provided with the screw mandrel 6 coordinating with it, driving mechanism 4 is connected on screw mandrel 6 and is driven screw mandrel to rotate by transmission mechanism.
A kind of net roller core shaft as above, forme mandrel pressuring flat device, is characterized in that being provided with through hole 11 on described bearing 1, and described nut 5 is placed in through hole and limits nut rotation, and described screw mandrel 6 is arranged on bearing 1 by screw mandrel bearing 7.
A kind of net roller core shaft as above, forme mandrel pressuring flat device, is characterized in that described transmission mechanism includes the swing arm 8 being fixedly connected on screw mandrel 6, is articulated with rotating shaft 9 in swing arm 8, and the other end of this rotating shaft 9 is articulated on described driving mechanism 4.
A kind of net roller core shaft pressuring flat device as above, is characterized in that described driving mechanism 4 is increased stroke-adjustable gas cylinder, drives the cylinder rod of cylinder to be fixedly connected on a rod end bearing 10, rod end bearing 10 and rotating shaft 9 pivot joints.
The present invention compared with prior art has the following advantages:
The present invention is from causing the sagging main cause of mandrel, according to the principle of lever, take spring bearing as fulcrum, adopt cylinder to drive screw mandrel, roller core shaft rear end is depressed, force roller core shaft front end axle head automatically to lift, mandrel front end can be pressed onto completely to the state of level, thus when the supporting seat of front end closes again very easily and flexibly.

Fig. 2 is the schematic diagram that cylinder connects swing arm.
Fig. 3 is the cooperation schematic diagram of screw mandrel and nut and roller core shaft.
[specific embodiment]
Below in conjunction with accompanying drawing, describe the present invention:
As shown in the figure, a kind of net roller core shaft pressuring flat device, comprises bearing 1 and is located at the roller core shaft 3 on bearing by spring bearing 2, is fixedly connected with driving mechanism 4 on bearing 1.At bearing 1, be provided with and can upper and lower slip also can be pressed in the nut 5 in roller core shaft 3 rearward end.In nut 5, be provided with the screw mandrel 6 coordinating with it.Driving mechanism 4 is connected on screw mandrel 6 and is driven screw mandrel to rotate by transmission mechanism.
Driving mechanism 4 actions also drive screw mandrel to rotate by transmission mechanism, because nut 5 can only upper and lowerly slide, and can not rotate, and screw mandrel promotes nut 5 down slidings, and 5, nut can suppress the end, rear end of roller core shaft 3.Like this, the front end of roller core shaft 3 from bearing move lower after, roller core shaft 3 can keep balance equally, the front end of roller core shaft 3 can be not sagging.
Specifically, on described bearing 1, be provided with through hole 11, described nut 5 is placed in through hole and limits nut rotation, and nut 5 can only upper and lowerly slide like this, and can not rotate.Described screw mandrel 6 is arranged on bearing 1 by screw mandrel bearing 7.
Described transmission mechanism includes the swing arm 8 being fixedly connected on screw mandrel 6, is articulated with rotating shaft 9 in swing arm 8, and the other end of this rotating shaft 9 is articulated on described driving mechanism 4.
Described driving mechanism 4 is for driving cylinder, drives the cylinder rod of cylinder to be fixedly connected on a rod end bearing on 10, rod end bearing 10 and rotating shaft 9 pivot joints.
Like this, when the front end of roller core shaft 3 being moved down from bearing, first start cylinder action, cylinder rod promotes swing arm 8 by rod end bearing 10 and rotates, thereby the rotation of swing arm 8 drives the rotation of screw mandrel 6, and screw mandrel promotes nut 5 down slidings, and 5, nut can suppress the end, rear end of roller core shaft 3.
