Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to the closing-in mould detailed description of the invention proposed according to the present invention, structure, feature and effect thereof, be described in detail as follows.
See Fig. 1 to Fig. 6, closing-in mould of the present invention, comprise base 1, closing in inner cone 3, closing in elasticity outer cone 6, wherein: positioning sleeve 2 is equipped with on base 1 top, it is inner that positioning support support set 7 is loaded on base 1, and closing in elasticity outer cone 6 is equipped with in positioning sleeve 2 inside, closing in elasticity outer cone 6 is placed in positioning support support set 7 top, closing in inner cone 3 coordinates and is contained in closing in elasticity outer cone 6 top, closing in inner cone 3 top is connected with gland 4, is placed in closing in elasticity outer cone 6 inside in the hole that alignment pin 5 is contained in positioning support support set 7.Closing in inner cone 3 and gland 4 are connected by wedge shape or step-like inner peripheral surface.Closing in elasticity outer cone 6 is two flap-type structures, and closing in elasticity outer cone 6 arranged outside has some axial groove A8 uniform vertically and axial groove B9.Axial groove A8 is the axial groove radially, axially all do not opened.Axial groove B9 is the axial groove radially opened and axially do not open.Alignment pin 5 is from up to down divided into closing in section 10, deformable transition section 11, supporting section 12, and the cylindrical section that deformable transition section 11 can be increased gradually by some sections of radiuses, boss section connect to form.
During use, see Fig. 7, the first step, is placed in the base 1 with positioning sleeve 2 and positioning support support set 7 on press base 16, second step, by aforementioned claim, threaded engagement is passed through with alignment pin 5 by being tightened up nut 13 by the parts of assembling of closing up, make to tighten up nut end face to contact with the end face A1 of alignment pin 5, thus realize tightening up the location of nut 13 on alignment pin 5, load positioning support support set 7 coordinating with the alignment pin 5 tightening up nut 13 again, its end face A2 is contacted with the end face A6 of base 1, thus realize tightening up the location of nut 13 in closing-in mould, 3rd step, loads positioning sleeve 2 the closing in elasticity outer cone 6 of two flap-type, and its end face A3 is contacted with the end face A6 of base 1, thus determines the about position of closing in elasticity outer cone 6 in closing-in mould, 4th step, closing in inner cone 3 is fitted by the inner conical surface on it and the male cone (strobilus masculinus) on closing in elasticity outer cone 6, it is made to be placed on closing in elasticity outer cone 6, under the self-gravity action of closing in inner cone 3 or under manual force effect, the closing in elasticity outer cone 6 of two flap-type is made to close as a whole, fitting or have certain interval in the closing in position that before closing in now on it, diameter and parts tighten up nut 13, thus determines the elaborate position of closing in elasticity outer cone 6 at closing-in mould, 5th step, by the hole on closing in inner cone 3, by aforementioned claim, parts union elbow 15 is coordinated loading alignment pin 5 from top to bottom, make the inner conical surface on union elbow 15 and the taper-face contact on alignment pin 5, thus realize the location of parts union elbow 15 in closing-in mould, 6th step, passing hole axle is engaged on closing in inner cone 3 and loads onto gland 4, 7th step, starting pressure machine, apply downward pressure to gland 4 by pressure extrusion 14 and make it drive closing in inner cone 3 to move down, in now closing in elasticity, outer cone 6 can not produce by the support of positioning support support set 7 and move down, thus make closing in inner cone 3 and closing in elasticity outer cone 6 produce relative movement at the conical surface place that fits, and then make closing in elasticity outer cone 6 by the effect of centripetal closing in power, the closing in section of the topmost of closing in elasticity outer cone 6 is made to produce centripetal radial displacement and before making closing in, diameter starts to diminish, when closing in inner cone 3 put into end face A4 contact with positioning sleeve 2 end face A5 time, tightened up nut 13 section of closing in diameter by cuff component and reach requirement, stop applying downward pressure to gland 4, press ram 14 is moved up playback, closing in process completes, 8th step, from mould, first passing hole axle coordinates taking-up gland 4, the assembly assembled closing up again, closing in inner cone 3, closing in elasticity outer cone 6, alignment pin 5 take out together from mould, because closing in elasticity outer cone 6 is two flap-type structures, manually be just easy to make itself and components apart, assembly with alignment pin 5 is taken out by the hole on closing in inner cone 3, and finally exit alignment pin 5 from derotation screw thread assembly, whole closing in assembling process terminates.Structure of the present invention is simple, highly effective, easy to operate, economic high-quality, and applicable overall dimensions two ends are large, centre is little and assembling position of closing up is in promoting the use of of the assembly closing in of assembly middle part.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
