Below at first traditional rotary cam structure is done to simple declaration.As shown in Figure 1, be the schematic diagram of rotary cam structure in prior art.
This rotating cam structure comprises cylinder 1, cam chair 2, cam 3, wedge slide block 4, guide plate 5 and wedge base 6.Wherein, cylinder 1 is connected with cam 3, cam chair 2 supporting cam wheels 3, cylinder 1 and wedge base 6, and guide plate 5 is fixed in an end of cam 3.
The function of above-mentioned each critical piece is as follows:
Cam 3: drive it by cylinder 1 as power source and rotate around fixed axis, thereby realize easily the side flanging forming process and send pickup, it is spacing that backhaul is established at cam 3 two ends, 4 slips of cam 3 and wedge slide block, and guide plate 5 plays the work position-limiting action simultaneously;
Cam chair 2: for cam 3 and cylinder 1 are played to the limited support effect, and establish oil groove to lubricate sliding surface, keep sliding with cam 3 and join;
Wedge base 6: to 5 position-limiting actions of guide plate that are fixed in cam 3, help wedge slide block 4 to realize moving back and forth;
Wedge slide block 4: be fixed as one with the side flanging piece, realize side flanging;
Self-oil feeder 7: cam 3 is established oil groove with cam chair 2 contact positions, and self-oil feeder 7 can be oily to oil groove continuously;
Guide plate 5: control the angle that cam 3 rotates, make it arrive assigned address, effectively to work.
The motion process of this rotating cam structure normal condition is as follows:
Cylinder stroke is in bottom dead centre, 3 rotations of band moving cam, the guide plate 5 that is fixed in cam contacts with wedge base 6, while is because wedge base 6 is spacing, cam 3 motions put in place, put part, and upper bolster and wedge slide block 4 move downward under the drive of lathe, wedge slide block 4 with along inclined-plane, move after guide plate 5 on being arranged on cam 3 contacts, complete flange.After this, wedge slide block 4 moves upward, until separate with counterdie, cylinder stroke arrives top dead-centre, and cam 3 backhauls arrive precalculated position, pickup.Then cylinder stroke arrives bottom dead centre, starts circulation next time.
In order to guarantee the parts flanged-edge quality, need to guarantee the slide guide gap (being generally 0.05mm) between cam and cam chair, and due to traditional bedding-in method make cam carry out again lappingout after quenching in the cam diameter diminish, and cam chair does not need to heat-treat, diameter does not change, after making the cam diameter diminish, with cam chair gap increase, discontinuity in the course of work, cause Quality Down after parts flanged-edge.
For the problems referred to above, the utility model provides a kind of guider, makes cam after heat treatment deformation, again by after the cam lappingout, also can guarantee the slide guide gap between cam and cam chair, and then guarantees to improve part quality by mould and die accuracy.
The guider that the utility model provides comprises: one group of guiding piece, the structure of these guiding pieces is identical.
As shown in Figure 2, be the structural representation of guiding piece in the utility model guider, Fig. 3 is that the P-P of Fig. 2 is to view; Fig. 4 is that the T-T of Fig. 2 is to view.
Described guiding piece comprises: slide guide face 21 and the installed surface 22 joined with described slide guide face 21, be provided with installing hole 23 on installed surface 22, and for described guiding piece is arranged on to cam chair, make described slide guide face 21 participate in the slide guide of cam.
In this embodiment, above-mentioned slide guide face 21 is cambered surface, and its radius is consistent with the external diameter of described cam.
In actual applications, the guiding piece of varying number can be set according to the length of cam chair slide guide face, be installed on respectively the diverse location of cam chair, as shown in Figure 5, in the scheme of installation of the utility model guider, guiding piece 100 is three, is arranged on respectively two ends and the centre position of described cam chair.Such as, the cam that length is less than 600mm need to arrange respectively above-mentioned guiding piece at corresponding cam chair two ends, and the cam that is greater than 600mm need to arrange respectively above-mentioned guiding piece at corresponding cam chair two ends and centre position.
Above-mentioned installing hole can be screw, for by screw, described installed surface 22 being fixed on to the trailing flank of described cam chair.
In actual applications, the material of described guiding piece can be selected carbon tool steel T10A, heat treatment hardness HRC58-62, and concrete size can be determined according to the structure of actual cam chair, such as being: long 140mm, wide 75mm, high 80mm.
Further, on described slide guide face 21, also be provided with described cam chair on the suitable oil groove (not shown) of oil guide groove.Described oil groove can be together with cam chair, to process after the piece that will lead is installed.
Utilize guider of the present utility model, can after the cam heat treatment deformation, again cam be carried out to lappingout, guarantee axiality.
Due to cam wearing and tearing at work, also can make cam produce distortion, in order to prevent further after lappingout, the diameter of cam being diminished, increase the gap between cam and cam chair.In the guider of the embodiment of the present invention, also can further comprise: pad (not shown) is arranged between the barricade face 24 and cam chair relative with slide guide face 21, for adjusting the slide guide gap between slide guide face 12 and cam.
For example: after heat treatment, lapping-in makes the cam diameter reduce 0.05mm, increases the pad of suitable thickness on so need to the barricade face relative at guiding piece slide guide face, to guarantee the rotation precision of cam, improves part quality.
It should be noted that, because described pad is arranged between guiding piece and cam chair, after the piece that will lead by screw is fastening, described pad is clamped between the two naturally, so pad does not need fixing separately.
In rotating cam holder structure with this guider, as shown in Figure 6, increase by one group of guiding piece on cam chair, the situation that can make the lappingout after the cam heat treatment deformation cause gap to increase is effectively solved, guarantee guiding clearance, improve the stability of mould.
Above the utility model embodiment is described in detail, has applied the specific embodiment herein the utility model is set forth, the explanation of above embodiment is just for helping to understand method and apparatus of the present utility model; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model simultaneously.
