Abstract

The utility model relates to a printing machine technical field, concretely relates to novel gravure printing roller, it includes roll body and the flange of connection at the roll body both ends, the roll body is connected with the second end of flange, roll body both ends inner wall department has seted up first recess, the second recess that matches with first groove phase is seted up in the second end outside of flange, the first end outside diameter of flange is unanimous with the outside diameter of roll body, flange second end inlay roll body. The utility model provides a flange second end inlay roll body, the first end of flange is outside at the roll body, and roll body length shortens relatively, practices thrift the roll body material, when welding roll body and flange, the mode of adoption roll body skin weld and complete penetration roll body, the operation degree of difficulty is low, and the welding is firm.

Description

Novel gravure roller

Technical field

This utility model relates to printer technology field, is specifically related to a kind of Novel gravure roller.

Background technology

The gravure printing roller that production and application preprinted by intaglio plate is the highest to the required precision of flange, gravure printing roller directly affects the printing chromatography that intaglio plate is preprinted, existing gravure printing roller is as shown in Figure 1: gravure printing roller uses end face weld, gets on the bus gradient 45-60 at flange 1, the chamfering of deep 8 10mm；Roll body 2 inwall car gradient 30, the chamfering of deep 7-8mm.Flange 1 be bumped into after roll body 2 manual with 4.0 welding rod built-up welding, then car planar end surface, the angle of falling R.This method has the disadvantage that 1, the flange 1 built-up welding amount of gravure printing roller is little, because of personnel's technological disparity, is susceptible to weld impermeable, rosin joint；2, at car planar end surface, behind the angle of falling R, a part for built-up welding is gone by car again, and difficulty of processing is big；3, intaglio plate preprints that roller is thick, weight big, and in press, flange 1 is subjected to the biggest inside top power, in use, often occurs because the former gravure printing roller that thus results in of flange 1 is scrapped or the problem of deterioration in accuracy.

Utility model content

The purpose of this utility model is to provide the Novel gravure roller of a kind of simple in construction, length in service life.

For achieving the above object, this utility model is by the following technical solutions: Novel gravure roller, including roll body and the flange being connected to roll body two ends, described roll body is connected with the second end of flange, the first groove is offered at the inwall of described roll body two ends, offering the second groove with the first groove match outside second end of described flange, described flange the first end outside diameter is consistent with the outside diameter of roll body, and flange the second end is bumped into roll body.

Thickness is roll body wall thickness the 1/2 of described first groove.

Height is flange height the 1/3 of described second groove.

Described roll body and flange are by roll body surface soldered and through welding roll body.

Compared with prior art, this utility model has the advantage that

1, roll body in this utility model is connected with the second end of flange, the first groove is offered at the inwall of roll body two ends, the thickness of the first groove is the 1/2 of roll body wall thickness, the second groove with the first groove match is offered outside second end of flange, the height of the second groove is the 1/3 of flange height, flange the first end outside diameter is consistent with the outside diameter of roll body, the design of this structure shortens the length of roll body, reduce the weight of roll body, save and manufacture roll body material therefor, flange the second end is bumped into roll body, first end is outside roll body, reduce the inside top power that flange is in use suffered, guarantee that flange will not in use go wrong, effectively prevent because flange reason causes roll body to scrap or the problem of deterioration in accuracy；

2, the roll body in this utility model uses the mode in roll body surface soldered to be connected with flange, roll body and flange are by roll body surface soldered and through welding roll body, use roll body surface soldered mode, reduce operation easier, convenient welding, and firm welding, solution conventional because the little welding of flange resurfacing welding amount is impermeable, the problem of rosin joint, and use the roll body surface soldered mode also can saving welding rod consumption.

Detailed description of the invention

The utility model discloses Novel gravure roller, as Figure 2-3, including roll body 2 and the flange 1 being connected to roll body 2 two ends, roll body 2 two ends inwall offers the first groove 21, and the thickness d of the first groove 21 is the 1/2 of roll body 2 wall thickness D, i.e. d=1/2D；Offering the second groove 13 matched with the first groove 21 outside flange the second end 12, the height h of the second groove 13 is the 1/3 of flange 1 height H, i.e. h=1/3H；The outside diameter of flange the first end 11 is consistent with the outside diameter of roll body 2, flange the second end 12 is bumped into roll body 2, flange the first end 11 is outside roll body 2, the design of this structure shortens the length of roll body 2, reduce the weight of roll body 2, save and manufacture roll body 2 material therefor, simultaneously, reduce the inside top power that flange 1 is in use suffered, guarantee that flange 1 will not in use go wrong, effectively prevent because the former roll body 2 that thus results in of flange 1 is scrapped or the problem of deterioration in accuracy, extend the service life of roll body 2.Roll body 2 uses the mode in roll body 2 surface soldered to be connected with flange 1, i.e. roll body 2 and flange 1 are by roll body 2 surface soldered and through welding roll body 2, and roll body 2 surface soldered mode reduces operation easier, convenient welding, when welding roll body 2 and flange 1, lathe installs NB-500 type CO additional₂Gas shielded welding machine, rotarily drives roll body 2 uniform rotation by lathe, regulates speed of welding according to the wall thickness D converter of roll body 2 and welds, improves the working environment of workman.NB-500 type CO₂When gas shield is welded in use 1mm welding wire, can the thickness of through welding 10-12mm, it is ensured that firm welding, solution conventional because the flange 1 little welding of built-up welding amount is impermeable, the problem of rosin joint, and use the roll body 2 surface soldered mode also can saving welding rod consumption.This utility model simple in construction, Financial cost is low, and service life is long.
