Description
Technical field
The utility model relates to the FlexbleJoint processing in the metal manufacturing, a kind of major diameter flange sylphon seal face leveling apparatus.
Background technology
Present domestic FlexbleJoint mostly is welded structure, though the safety coefficient of the compensator equipment that this mode is made is bigger, the comparison heaviness but compensator integral body seems, also having because of welding high temperature institute changes to the localized metallic material character influences the life-span, and equipment cost obviously wants high.In order to save the FlexbleJoint manufacturing cost, and the service life of improving FlexbleJoint, the version of domestic FlexbleJoint changes, promptly be designed to the structure that bellows flange and sealing are joined, but the sealing surface flatness becomes the difficult problem that this structure need solve behind the flange, and flatness does not reach and requires directly to influence the product hermeticity energy.For the processing of the above bellows of major diameter Φ 800mm, the big more problem of the width of flange face is outstanding more, and existing technological equipment can't meet design requirement, and must redesign special equipment and could solve this difficult problem.
Summary of the invention
The purpose of this utility model provides a kind of major diameter flange sylphon seal face leveling apparatus, improves flange facial plane degree, and the control slip is to improve product percent of pass and overall performance.
A kind of major diameter flange sylphon seal face leveling apparatus, comprise upper cover plate assembly, bloated tire assembly and vertical lathe system, it is characterized in that: the base center of circle of the tire assembly that expands is provided with mandrel, support bar with the flange positioned vertical at its two ends in perimeter, bloated lobe gripper shoe, pressure awl, nut place on the mandrel path, and the lobe that expands is bored the inclined-plane with pressure and contacted; The upper cover plate assembly comprises that periphery has the roller disk of roller, and the pressing plate of upper cover plate assembly is placed in the mandrel upper end of round concave table in the roller disk by bearing and trip bolt; The upper cover plate assembly is maintained fixed by pin and vertical lathe lathe bed, and base places the lathe chassis, and is rotatable.
The slip of control FlexbleJoint is the core content that guarantees product quality, and for turnup structure, leakage problem mostly occurs at flange sealing surface place.The design has designed this special tooling in order to satisfy the degree designing requirement of flange sylphon seal facial plane, and this device also is applicable to the smoothing of the big flange of all bellowss simultaneously.Adopt the flatness of the method raising flange sealing surface of tapered roller spinning, to guarantee the product overall performance.This device is by the special equipment motor-driven, and tapered roller rolls along flange face circumferencial direction, by the frequency converter frequency control of vertical lathe system, keeps given pace in the rolling process, rolling rate and the number of turns different thicknesss of slab of foundation and the bellows number of plies and decide.The tire that expands becomes as a whole with FlexbleJoint, does not relatively move, and tapered roller does not damage sealing surface, unload the upper cover plate assembly after, utilize dial gauge on-line measurement sealing surface flatness.
Description of drawings
Fig. 1 is a major diameter flange sylphon seal face leveling apparatus cutaway view;
The specific embodiment
This major diameter flange sylphon seal face leveling apparatus, as shown in Figure 1, comprise upper cover plate assembly, bloated tire assembly and vertical lathe system, it is characterized in that: base 1 center of circle of the tire assembly that expands is provided with mandrel 2, support bar 22 is placed in base 1 periphery with the flange 20 at FlexbleJoint two ends, and the lobe gripper shoe 3 that expands, pressure awl 4, nut 9 coaxial placing on mandrel 2 paths are expanded lobe 6 on bloated lobe gripper shoe 3, contact with the pyramid inclined-plane of pressing awl 4; The upper cover plate assembly comprises that periphery has the roller disk 10 of tapered roller 17, roller 17 passes through roller shaft 16 tiltably-mounteds in the groove of roller disk 10 cylindricals, pressing plate 12 circle center holes place mandrel 2 path tops, ball bearing 15, place interior round concave table, the mandrel top of roller disk 10, fixing by pressing plate 12 and trip bolt 11, thrust bearing 14 is placed on the pressing plate 12 by mandrel 2, adds nut 13 again; Upper cover plate is fixed by pin 18 and vertical lathe lathe bed, and base 1 places the lathe chassis.
The bloated lobe 6 of bloated tire assembly is a plurality of sector disks, and its sector disk is installed pulling force hook 8, and radially is provided with gain at the screw of the lobe 6 relative expanding lobe gripper shoes 3 that expand, and guide post 5 is connected with the screw of bloated lobe gripper shoe 3 by lobe 6 gains that expand; The inclined-plane matches with pressing awl 4 awl inclined-planes in the sector disk.Guide post 5 guarantees that bloated lobe 6 moves along the lobe gripper shoe 3 that expands is radially smooth and easy.Elastic plastic ring 7 is suspended on the pulling force hook 8 of a plurality of bloated lobes 6 on the circumference, and after unclamping nut 9, elastic rubber ring 7 tightens up bloated lobe 6 is returned to original position.
The periphery of roller 17 is a taper seat in the upper cover plate assembly, and in the groove of roller disk 10 peripheries, tapered roller 17 taper seats protrude in roller disk 10 lower surfaces, conical base perpendicular to mandrel 2 by roller shaft 16 tiltably-mounteds, fits with FlexbleJoint flange sealing surface.
Roller disk 10 circle centre position pressing plates 12 upper and lower has thrust axle sleeve 14 and ball bearing 15 respectively in the upper cover plate assembly, and the upper cover plate assembly can move up and down at mandrel, with the control roll extrusion amount of feeding.
This device Job Operations step is as follows:
1, earlier the bloated tire assembly (above-mentioned parts 1-8) of special-purpose bellows is installed on the vertical lathe chassis 23, FlexbleJoint integral body is put into the bloated tire assembly of special-purpose bellows, the flange position is placed respectively in the table top of upper and lower flange, rotation support bar 22 is to base 1 screwed hole, manual adjustments rotation nut 21 makes FlexbleJoint flange sealing surface level;
