Description

Cone-shaped inner hole lopps rolles over ring forging saddle support
Technical field
The utility model relates to a kind of forging technology and pattern assembly, is specifically related to a kind of cone-shaped inner hole lopps and rolles over ring forging saddle support.
Background technology
Forging products range of application is extremely extensive, is that current industrial manufacturing industry use amount is large, the industrial products of wide application.The feature of current endoporus taper ring forgings is that specification is wide in variety, and batch is little, and larger endoporus taper ring forgings generally adopts numerical control rolling machine to roll over and makes type, saves a large amount of raw material than traditional free forging method.The prefabricated blank cross section shape size of this forging before rolling over ring is very crucial, will directly affect the capacity distribution of the blank of rolling over ring and the forging quality after being shaped.The prefabricated blank that usual endoporus taper lopps rolles over ring forging is that endoporus is made inclined hole or straight hole, and roll over ring like this when being shaped due to initial stock volume unreasonable distribution, easily form upper external cylindrical surface depression because of scarce material, the mass defects such as line are folded in upper surface.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of cone-shaped inner hole lopps to roll over ring forging saddle support, change the capacity distribution of initial base materials, improve the rolling quality of endoporus taper ring forgings, material saving, reduces production cost.
Cone-shaped inner hole lopps described in the utility model rolles over ring forging saddle support, comprise two saddle support pedestals, on two saddle support pedestals, level is provided with cone saddle, be provided with reaming section in the middle part of cone saddle, reaming section comprises cylindrical section and round platform section, and the diameter of cylindrical section is less than the diameter of cone saddle, cylindrical section one end is connected with the transition of cone saddle, the cylindrical section other end is connected with round platform section upper bottom surface, and round platform section bottom surface is connected with cone saddle, and round platform section upper bottom surface diameter is less than bottom surface diameter; Forcing press tup is provided with above reaming section.
Adopt the cone saddle of this structure to carry out reaming base, increase inner hole cone shape Forging prefabricated blank upper blank, thus it is more reasonable that blank is distributed, and reaches desirable base cross sectional shape.
Described cone saddle and the reaming section of boring on saddle are structure as a whole, and rotate reaming and stablize, keep good axiality.
The bottom surface diameter of described round platform section is greater than cone saddle diameter.
The beneficial effect that the utility model is compared with prior art had is:
It is reasonable in design that cone-shaped inner hole lopps rolles over ring forging saddle support, and the capacity distribution of initial base materials by the structural change of reaming section, improves the rolling quality of endoporus taper ring forgings, material saving, reduce production cost, the market competitiveness of raising forging products.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, cone-shaped inner hole lopps is rolled over ring forging saddle support and is comprised two saddle support pedestals 5, on two saddle support pedestals 5, level is provided with cone saddle 4, reaming section is provided with in the middle part of cone saddle 4, reaming section comprises cylindrical section 3 and round platform section 2, the diameter of cylindrical section 3 is less than the diameter of cone saddle 4, cylindrical section 3 one end is connected with the transition of cone saddle 4, cylindrical section 3 other end is connected with round platform section 2 upper bottom surface, round platform section 2 bottom surface is connected with cone saddle 4, round platform section 2 upper bottom surface diameter is less than bottom surface diameter, and the bottom surface diameter of round platform section 2 is greater than cone saddle 4 diameter; Forcing press tup 1 is provided with above reaming section.
Cone saddle 4 and the reaming section of boring on saddle 4 are structure as a whole.
Endoporus taper is rolled over ring preform 6 and is required that cross sectional shape as shown in Figure 2, according to Fig. 3-Fig. 5, its specific embodiment is as described below, first blank 7 is being forged into discoid, rushing small taper hole with tapered punch 8 smooths whole, then by after blank 7 post bake, coordinates forcing press tup 1 to carry out reaming with this structure saddle support, obtain preform 6, finally roll over the core roller of ring rolling machine 9 of numerical control rolling machine and make shape.
