Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of needle roller thrust bearing pad fore shaft compacting tool set as shown in Figure 1, justifies for the pad 17 in needle bearing
All uniform lock points for suppressing radially inward projection, to pin retainer and ensure that the flexible rotating of frame.The mould
With bottom plate 1, the cavity plate being fixed on bottom plate 12, it is correspondingly arranged at the upper mould 3 of the surface of cavity plate 2 and is fixed on upper mould 3
The die shank 4 of end face.
Described cavity plate 2 has the inner barrel positioned at lumen centers, and bottom is provided with inner barrel and is fixed on bottom plate 1
Support tube 5, upper end is slidably fitted with the material returned cylinder 6 of support pad 17 in support tube 5, is connected between material returned cylinder 6 and bottom plate 1
Material returned cylinder 6 is set to reply the 4th spring 14 of initial position in company with pad 17 after the completion of compacting.
Cavity plate 2 on the upper surface of support tube 5 is circumferentially evenly equipped with four sliding blocks 7, and the sliding block 7 is arranged at cavity plate 2
Between the inner barrel of periphery wall and cavity plate 2, the outer end of sliding block 7 has outer chamfering inclined-plane 7-1, the described inner chamber bottom of upper mould 3
With interior chamfering inclined-plane 3-1, when upper mould 3 is moved down, coordinated by interior chamfering inclined-plane 3-1 and outer chamfering inclined-plane 7-1, upper mould 3 is promoted
The sliding block 7 is made to move radially along cavity plate 2 and force in the outer peripheral face of pad 17.
Punch-pin 8 is provided with positioned at the upper lumen centers of mould 3, punch-pin 8 is driven by upper mould 3 and moved, and the upper inner chamber top of mould 3 is fixed with
Pressing plate 10, the upper end of punch-pin 8 is stuck between the endoporus step of pressing plate 10 and the bottom surface of die shank 4 and clamping, and punch-pin 8 is circumferential to be evenly equipped with four
The fore shaft support block 9 of circle is encircled into, there is mould 3 in bulge loop 9-1, bulge loop 9-1 protrusions to go to the bottom on the described base of fore shaft support block 9
There is internal diameter to be slightly smaller than the interior step surface 9-2 of the diameter of punch-pin 8 for side, the bottom of fore shaft support block 9, when upper mould 3 drives the punch-pin 8 to move down,
The lower end of punch-pin 8 top opens the interior step surface 9-2 and four fore shaft support blocks 9 is synchronously outwards strutted, so that fore shaft support block 9
Bulge loop 9-1 be supported in the inner peripheral surface of pad 17.
Loop bar 15 is connected between the pressing plate 10 and fore shaft support block 9, is connected between pressing plate 10 and fore shaft support block 9
The first spring 11 of the upper surface of fore shaft support block 9 is pressed on, the first spring 11 is sleeved on loop bar 15, the upper side wall peace of mould 3
Equipped with spring guide 16, the second spring 12 for making fore shaft support block 9 radially reset after the completion of compacting is installed in spring guide 16,
The front end of second spring 12 is connected with fore shaft support block 9, and being set with the sliding block 7 after the completion of suppressing makes four sliding blocks 7 synchronous
The 3rd spring 13 resetted.
The course of work is summarized as follows:Pad 17 to be processed is set on material returned cylinder 6, when upper mould 3 is overall to be moved down,
The first contact pins 17 of fore shaft support block 9, now upper mould 3 is overall and pad 17 continues to move down, and reaches the position of support tube 5, pad
Piece 17 and four fore shaft support blocks 9 stop moving down, and the precompression of the first spring 11 prevents pad 17 from moving, and upper mould 3 is overall
Continue to move down, now the top of punch-pin 8 opens the interior step surface 9-2 and makes four fore shaft support blocks 9 synchronously outwards strut so that
The bulge loop 9-1 of fore shaft support block 9 is supported on the crimp inner peripheral surface before pad 17 is processed, and upper mould 3 is overall to be continued to move down, on
There is the inner chamber bottom of mould 3 interior chamfering inclined-plane 3-1 to be contacted with the outer chamfering inclined-plane 7-1 that the outer end of sliding block 7 has, when upper mould 3 it is overall after
It is continuous when moving down, pass through interior chamfering inclined-plane 3-1 and outer chamfering inclined-plane 7-1 mating reactions, upper mould 3 promotes four synchronizations of sliding blocks 7
Work forces in the outer peripheral face of pad 17 along the moving for radial direction of cavity plate 2, due to the supporting role of four fore shaft support blocks 9, pad 17
Sliding block 7 will not be followed to move, when sliding block 7 moves to reach certain position, i.e., uniformly four are suppressed on the crimp circumference of pad 17
To the lock point that the internal diameter direction of pad 17 is raised, the fore shaft width requirement of pad 17 is met.After the completion of compacting, upper mould 3 is overall to moving up
Dynamic, now four sliding blocks 7 are reset to initial position by the 3rd spring 13, and the 4th spring 14 promotes material returned cylinder 6 and pad 17 upward
It is mobile, send the pad 17 processed back to initial position, second spring 12 radially rebounds in direction four fore shaft support blocks 9
Initial position, pad 17 is completely disengaged from upper mould 3, and upper mould 3 returns to initial position, and the pad 17 processed is taken out, whole to add
Work is completed.
Using the above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
