Abstract
The invention discloses a tapered thermal expansion reshaping mould and aims to realize zero clearance fit during the process of assembling with a reshaped thin-wall cylinder and increase the thermal expansion reshaping quality. The tapered thermal expansion reshaping mould comprises a sectioning cone, a taper expansion body, a limiting plate and a tightening nut, wherein the cone petals at the front end of the sectioning cone are separated; the rear end of the sectioning cone is integrated; a tapered surface of the sectioning cone is matched with the tapered surface of the taper expansion body; the tapered angles are in consistent size; a screw rod is arranged on the taper expansion body; a through hole is arranged in the limiting plate; the screw rod is in threaded connection with the tightening nut through the through hole.
Description
Technical field
The present invention relates to a kind of heat expansion school shape mold, particularly a kind of taper heat expansion school shape mold of thin cylinder.
Background technology
The high thin cylinder of required precision is added in process at shaping or machine and needs to correct shape, as needed to correct shape to after thin cylinder rotary press modelling, also school shape is needed because welding stress exists locally to stay at weld after the outer suspension member of thin cylinder welding, at present the domestic heat expansion method that generally adopts is corrected shape thin cylinder, what heat expansion method school shape generally adopted is straight tube shape heat expansion school shape mold, its shortcoming is: will ensure matched in clearance because of straight tube shape heat expansion mold with when being assembled by school shape cylindrical shell, if gap is too small, assemble difficulty, if extra clearance, sizing precision declines, and then affect heat expansion school form quality amount.
Summary of the invention
Technical problem to be solved by this invention: the problem solving the then sizing precision decline of the too small then assembling difficulty in shape mold assembled gap, current straight tube shape heat expansion school and excesssive gap, provides a kind of taper heat expansion school shape mold with realizing zero clearance when being assembled by school shape thin cylinder and coordinate.
For solving the technical problem existed, the technical solution used in the present invention is: taper heat expansion school shape mold comprises distinguish cone, tapered expansion body, position-arresting disk, tightening nut, distinguish cone adopts front-end-cone lobe place separately, rear end is an entirety, the conical surface of distinguish cone and the conical surface of tapered expansion body cooperatively interact and angle of taper consistent size, tapered expansion is physically provided with screw rod, and position-arresting disk is provided with through hole, and screw rod is threaded with tightening nut through through hole.Described screw rod end face is provided with the structure of tetragonal body; Described distinguish cone material selection mild steel; The stainless steel material that the thermal coefficient of expansions such as described tapered expansion body material selection 1Cr18Ni9Ti or 1Cr18Ni9 or 0Cr18Ni9Ti are large; Described tightening nut because of with tapered expansion body screw rod with the use of, tightening nut material, tapered expansion body material are consistent with nut stem material.
Use taper heat expansion school shape mold to the installation step that thin cylinder carries out heat expansion school shape is: be placed in the endoporus of thin cylinder after distinguish cone and tapered expansion body cone match, and then distinguish is bored synchronously strut namely to complete assembling when distinguish cone cone lobe cylindrical all contacts bowlder in thin cylinder with tightening nut tension after screw rod position-arresting disk being inserted tapered expansion body, now just can realize taper heat expansion school shape mold and coordinate requirement with by the zero clearance during shape Assembly of the parts of school.
Beneficial effect of the present invention: it is simple that the present invention has structure, easy to operate, assembling and the high feature of heat expansion sizing precision, principle that radial direction struts simultaneously realizes school, heat expansion school shape to utilize the relative motion of two conical surface bodies that distinguish is bored, meet the matching requirements of zero clearance, heat expansion school shape Quality advance.
Accompanying drawing explanation
Fig. 1 is the topology view of taper heat expansion school shape mold, wherein, comprises distinguish cone 1, tapered expansion body 2, position-arresting disk 3, tightening nut 4, thin cylinder 5, screw rod 6;
Fig. 2 is the topology view of distinguish cone 1;
Fig. 3 is the topology view of tapered expansion body 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described:
Shown in Fig. 1, taper heat expansion school shape mold comprises distinguish cone 1, tapered expansion body 2, position-arresting disk 3, tightening nut 4, distinguish cone 1 adopts front-end-cone lobe place separately, rear end is an entirety, the distinguish cone conical surface of 1 and the conical surface of tapered expansion body 2 cooperatively interact and angle of taper consistent size, tapered expansion body 2 is provided with screw rod 6, and position-arresting disk 3 is provided with through hole, and screw rod 6 is threaded with tightening nut 4 through through hole.Described screw rod 6 end face is provided with the structure of tetragonal body; Described distinguish bores 1 material selection mild steel; The stainless steel material that the thermal coefficient of expansions such as described tapered expansion body 2 material selection 1Cr18Ni9Ti or 1Cr18Ni9 or 0Cr18Ni9Ti are large; Described tightening nut 4 material, tapered expansion body 2 material are consistent with screw rod 6 material.
Use taper heat expansion school shape mold to the installation step that thin cylinder 5 carries out heat expansion school shape is: be placed in the endoporus of thin cylinder 5 after distinguish cone 1 and tapered expansion body 2 cone match, and then distinguish is bored synchronously strut to bore lobe cylindrical when distinguish cone 1 with tightening nut 4 tension after the screw rod 6 position-arresting disk 3 being inserted tapered expansion body 2 and all contact bowlder in thin cylinder 5 and namely complete assembling, the zero clearance that now just can realize when taper heat expansion school shape mold assembles with thin cylinder coordinates requirement.
Above-mentioned is the special description made the present invention.For a person skilled in the art, any improvement and substituting not departing from spirit of the present invention all falls within the scope of protection of the present invention.Protection scope of the present invention limited with its claim.
