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 the 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 are a side fixed support of transmission, a side of operation is movable supporting.After a side bearing of operation was opened, the mandrel front end all can be sagging, and sagging main cause is that mandrel is overweight, and is long, and mandrel produces distortion, and a side of transmission supports built on the sand, and flexible distortion causes, the size of sag of chain according to the weight of mandrel with length and different.Like this, when again closing the bearing of operation one side, sagging because of the 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 the time, though can close bearing, effort is very large, and easily with the front end damage of bearings; If sag of chain is larger, mostly be and use the 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 roller core shaft 3 on the bearing by spring bearing 2, be fixedly connected with driving mechanism 4 at bearing 1, being provided with at bearing 1 can upper and lower slip and can be pressed in nut 5 on roller core shaft 3 rearward end, be provided with the screw mandrel 6 that cooperates with it in nut 5, driving mechanism 4 is connected on the screw mandrel 6 by transmission mechanism and drives screw mandrel and rotates.
Aforesaid a kind of net roller core shaft, forme mandrel pressuring flat device is characterized in that being provided with through hole 11 at described bearing 1, and described nut 5 places through hole and limits nut rotation, and described screw mandrel 6 is arranged on the bearing 1 by screw mandrel bearing 7.
Aforesaid a kind of net roller core shaft, forme mandrel pressuring flat device is characterized in that described transmission mechanism includes the swing arm 8 that is fixedly connected on the screw mandrel 6, are articulated with rotating shaft 9 in swing arm 8, and the other end of this rotating shaft 9 is articulated on the described driving mechanism 4.
Aforesaid a kind of net roller core shaft pressuring flat device is characterized in that described driving mechanism 4 is increased stroke-adjustable gas cylinder, and the cylinder rod that drives cylinder is fixedly connected on the rod end bearing 10, and rod end bearing 10 articulates with rotating shaft 9.
The present invention compared with prior art has the following advantages:
The present invention is from causing the sagging main cause of mandrel, principle according to lever, take spring bearing as fulcrum, adopt cylinder to drive screw mandrel, the roller core shaft rear end is depressed, force roller core shaft front end axle head automatically to lift, the mandrel front end can be overwhelmed fully the state of level, thus when the supporting seat of front end closes again very easily and flexibly.

[specific embodiment]
Describe the present invention below in conjunction with accompanying drawing:
As shown in the figure, a kind of net roller core shaft pressuring flat device comprises bearing 1 and is located at roller core shaft 3 on the bearing by spring bearing 2, is fixedly connected with driving mechanism 4 at bearing 1.Being provided with at bearing 1 can upper and lower slip and can be pressed in nut 5 on roller core shaft 3 rearward end.In nut 5, be provided with the screw mandrel 6 that cooperates with it.Driving mechanism 4 is connected on the screw mandrel 6 by transmission mechanism and drives screw mandrel and rotates.
Specifically, be provided with through hole 11 at described bearing 1, described nut 5 places 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 the bearing 1 by screw mandrel bearing 7.
Described transmission mechanism includes the swing arm 8 that is fixedly connected on the 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 the described driving mechanism 4.
Described driving mechanism 4 is for driving cylinder, and the cylinder rod that drives cylinder is fixedly connected on the rod end bearing on 10, and rod end bearing 10 articulates with rotating shaft 9.
Like this, when the front end of roller core shaft 3 will being moved down from bearing, then start first the cylinder action, cylinder rod then 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 then promotes nut 5 down slidings, and 5 on nut can suppress the end, rear end of roller core shaft 3.
