Abstract
The utility model discloses an improvement structure of a metal cylinder body spinning machine, which comprises a mandrel, a spinning part and a first support rotary part, one end of the mandrel is arranged on the first support rotary part, the other end of the mandrel is provided with a second support rotary part, the second support rotary part lies against the center of the mandrel end surface. Adopting the structure, under the actions of the first support rotary part and the second support rotary part, the rotating stability of the mandrel can be improved, thereby avoiding the bending deformation of the mandrel, and improving the wall thickness uniformity, straight-line degree, cylinder property and smoothing property of the thin-wall metal cylinder body.
Description
Technical field:
The utility model relates to a kind of structure-improved of metallic cylindrical body spinning machine.
Background technology:
Usually, as the roller of blooming manufacturing, nano impression, big miniature electric imaging formula printer usefulness, high accuracy printing, use wall thickness is polystyrene film, the polyimide film manufacturing of 0.03～0.3mm scope more.Also have in addition, in nickel plating, electroplate, adopt from parent and extract the nickel electrocasting making of having separated out the electroform products of nickel metal at the cylindrical shape parent out.
The roller of such use, because in the operation of processing such as heating continuously, pressurize, cool off, peel off, use, thus wish to have good heat conductivity, hear resistance, in addition, because of using, so also need outstanding fatigue strength, rigidity as rotary body.
But if the resin material that adopts polystyrene, polyimides one class is during as roll body, the heat conductivity of roll body is poor, and adopts the nickel electoformed product as roll body, though its heat conductivity is outstanding, can cause thermal embrittlement under the temperature more than 200 ℃.So in the PRN device industry, the roll body that adopts above-mentioned two kinds of materials to make is withdrawn from the market gradually, the substitute is the roll body that adopts thin-wall metal cylinder body to make.
Existing thin-wall metal cylinder body all is to adopt the production of rotary pressing processing machine, this rotary pressing processing machine mainly is made of mandrel and spinning parts, production process be cylindric plain pipe box on mandrel, utilize spinning roller that cylinder voxel pipe outer wall is carried out plastic working, pipe wall body attenuation of cylinder voxel and stretching, extension vertically, but at present to rotary pressing processing machine mandrel, only support the one end, the other end is unsettled, for example shown in Figure 1, this to the single-ended supporting construction of mandrel in the process of rotary pressing processing because the strength and stiffness of mandrel are limited, add mandrel and rotate at a high speed, when the spinning parts push cylindric plain pipe, mandrel can produce flexural deformation, is using this mandrel to carry out rotary pressing processing, the wall thickness homogeneity of the cylinder of being produced, linearity, all non-constant such as cylinder and flatness, particularly for the required metallic cylindrical body of PRN device, its wall thickness requires below 0.05mm, and mandrel has slight flexural deformation slightly, all can cause the generation of waste product.
For example, the cylindric plain pipe of the SUS304 stainless steel of internal diameter 40mm, wall thickness 0.3mm, long 100mm is installed on the mandrel of internal diameter 40mm, long 600mm, carry out rotary pressing processing, generate the thin cylinder metallic object of internal diameter 40mm, wall thickness 0.05mm, long 500mm, owing to be subjected to the extrusion load of spinning parts, the end unsettled at mandrel can produce bigger bending stress, compression stress during rotary pressing processing.Consequently, mandrel produces crooked.Through its deflection of experimental measurement gained is 0.5mm.The internal diameter of above-mentioned finished product can produce the error of positive and negative 0.5mm.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, to provide a kind of mandrel not produce the spinning machine of bending and spin stabilization.
For achieving the above object, the technical scheme that the utility model provides is: a kind of structure-improved of metallic cylindrical body spinning machine, include mandrel, spinning parts and the first support rotary part, one end of mandrel is arranged on first and supports on the rotary part, is provided with second at the other end of mandrel and supports rotary part.
Second supports rotary part against the center of living the mandrel end face.
After adopting said structure, supporting rotary part and second first supports under the acting in conjunction of rotary part, can play and improve the mandrel stability of rotation, avoid mandrel flexural deformation to occur, improve wall thickness homogeneity, linearity, cylinder and the flatness of thin-wall metal cylinder body.
Description of drawings:
Fig. 1 is the structural representation of prior art spinning machine;
Fig. 2 is the structural representation of the utility model spinning machine.
The specific embodiment:
Now elaborate the utility model in conjunction with the accompanying drawings:
The structure-improved of this metal cylinder spinning machine, include mandrel 1, spinning parts 2 and the first support rotary part 3, one end of mandrel 1 is arranged on first and supports on the rotary part 3, the other end at mandrel 1 is provided with the second support rotary part, 4, the second support rotary parts 4 against the center of living the mandrel end face.
The structure of present embodiment as shown in Figure 2, cylindric plain pipe 5 is installed on mandrel 1, edge shape 51 is processed in the inboard of the cylindric plain pipe bottom here, thereby make plain pipe bottom reserve through hole, convenient second supports the end face center that rotary part 4 withstands mandrel 1, mandrel 1 passes through with the rotation of two end supports state, thereby it is crooked to prevent that mandrel 1 from producing when rotated, can improve evenness of wall thickness, linearity and the cylindricity of metallic cylindrical body.
In addition, the periphery of the plain pipe 5 of spinning parts 2 corresponding circle tubulars is with three of the arranged spaced of 120 degree, can parallel spinning parts 2 bestows the pressure of mandrel 1 in process, prevents that mandrel 1 from bending.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
