Abstract
A kind of cylinders of printing press, including inner cylinder, outer barrel and middle cylinder；Link of boards is used between described inner cylinder and middle cylinder；Described outer barrel is socketed on middle cylinder.The utility model cylinders of printing press is made up of three layers of cylinder, the middle small inner cylinder of cylinder inner sleeve, connected between middle cylinder and inner cylinder with bearing rib, the intensity and rigidity of roller can fully be ensured, outer barrel employs ZL205A aluminium condensation materials simultaneously, wearability, the corrosivity of the industrial chemicals such as acid resistance ink, alcohol, water is excellent；Meanwhile, titanium alloy is lighter, reduces roller total quality, so as to reduce the power of motor, saves the energy.
Description
Technical field
The utility model is related to printing machine field of mechanical technique, more particularly to is a kind of cylinders of printing press.
Background technology
Cylinders of printing press is the core component of printing machinery, its surface smoothness, geometric accuracy height can be to printed matter
Quality produce and have a strong impact on, especially in the exquisite printed matter of printing, a bit error can all reduce the overall effect of printed matter
Really.Existing printing machine generally uses the cast iron quality of individual layer tube structure, because density of material is than larger, cause drum weight and
Inertia is all very huge, therefore needs larger motor to drive in machine operation procedure, using the cylinder knot of individual layer
Structure, the intensity and structural stability of roller have deficiency.
Utility model content
In order to solve the above-mentioned technical problem, the utility model purpose is：A kind of cylinders of printing press is provided, to solve print at present
The problem of brush machine cylinder is worn no resistance, perishable, coating is easily peeled off.
The technical scheme that the utility model is used is：A kind of cylinders of printing press, including inner cylinder, outer barrel and middle cylinder；It is described
Inner cylinder and middle cylinder between use link of boards；Described outer barrel is socketed on middle cylinder；Described middle tube outer surface is provided with indent
Trapezoidal dovetail groove；The trapezoidal coattail strip of evagination is provided with the inside of described outer barrel；Described middle cylinder and inner cylinder are made up of magnesium alloy；
Described outer barrel is made up of ZL205A aluminium alloys；Described outer barrel thickness is 5mm；Described middle barrel thickness is 20mm.
Further, described trapezoidal depth of dovetail is 10mm；Described trapezoidal dovetail groove totally 5, and be distributed on
On cylinder.
Further, described inner cylinder is provided with a bearing；Described inner diameter of steel flue is between 220mm ~ 550mm.
Further, described reinforcing plate number is 5；Described gusset is distributed on inner cylinder, and under trapezoidal dovetail groove
Side.
Further, the trapezoidal coattail strip number on described outer barrel is identical with trapezoidal dovetail groove；Described trapezoidal dovetail
It is interference fit between bar and middle cylinder.
The utility model has advantages below：Cylinders of printing press tube structure described in the utility model is at least by three layers of circle
Cylinder is constituted, and the middle small inner cylinder of cylinder inner sleeve connects between middle cylinder and inner cylinder with bearing rib, can fully ensure the intensity and just of roller
Property, middle cylinder outside is further strengthened the hardness of cylinders of printing press in the outer barrel that one ZL205A aluminium alloy of socket is made, reduced whole
Weight, is further ensured that the precision of roller is steady in a long-term.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Label declaration：Inner cylinder 1, outer barrel 2, middle cylinder 3, gusset 4, trapezoidal dovetail groove 5, trapezoidal coattail strip 6.

Between connected with gusset 4；Described outer barrel 2 is socketed on middle cylinder 3；The described outer surface of middle cylinder 3 is provided with the trapezoidal swallow of indent
Stern notch 5；The described inner side of outer barrel 2 is provided with the trapezoidal coattail strip 6 of evagination；Described middle cylinder 3 and inner cylinder 1 is made up of magnesium alloy；Institute
The outer barrel 2 stated is made up of ZL205A aluminium alloys；The described thickness of outer barrel 2 is 5mm；The described thickness of middle cylinder 3 is 20mm.
Further, the described depth of trapezoidal dovetail groove 5 is 10mm；Described trapezoidal dovetail groove 5 totally 5, and be distributed on
On middle cylinder 3.
Further, described inner cylinder 1 is provided with a bearing；The described diameter of inner cylinder 1 is between 220mm ~ 550mm.
Further, described reinforcing plate number is 5；Described gusset 4 is distributed on inner cylinder, and positioned at trapezoidal dovetail groove 5
Lower section.
Further, the number of trapezoidal coattail strip 6 and trapezoidal dovetail groove 5 on described outer barrel 2 are identical；Described trapezoidal swallow
It is interference fit between tail bar 6 and middle cylinder 3.
Above-described embodiment is only to illustrate technical concepts and features of the present utility model, and its object is to allow be familiar with technique
Personage can understand content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover protection domain of the present utility model it
It is interior.
