Abstract
The utility model relates to the technical field of mold manufacture, and particularly relates to a rotary cam structure provided with a guide roller unit. The rotary cam structure comprises an air cylinder, a cam seat, a cam, a guide plate, an inclined wedge base seat and the guide roller unit, wherein the air cylinder is connected with the cam, the cam seat supports the cam, the air cylinder and the inclined wedge base seat, and the guide roller unit and the guide plate are fixed at one same end of the cam. Due to the facts that the guide roller unit is designed, rollers are arranged on the guide roller unit, when the air cylinder is invalid in return, the rollers of the guide roller unit contact with an inclined wedge sliding block before the guide plate, the cam is driven to return, the phenomena that the sliding block collides with the guide plate, even stamping equipment is damaged, are avoided, potential safety hazards re greatly reduced, accidents are avoided, and cost is saved.
Description
Technical field
The utility model relates to the mold machining technology field, relates in particular to a kind of rotating cam structure.
Background technology
The vehicle of automobile is more and more now, the assembling process of vehicle body also becomes increasingly complex, various Novel punching techniques and Novel die structure emerge in an endless stream, tradition adopts the primary and secondary wedge structure, developed into afterwards the rotating cam structure, this mechanism is in the problem that solves automobile panel product punching press negative angle flange, flanging die dodged the straight line in product negative angle zone be converted into rotating avoiding, compare traditional primary and secondary wedge structure, it is strong that the rotating cam structure has stability, compact conformation, easy to assembly, the characteristics such as the frock cost is low.But in this structure, in case as the cylinder deactivation of drive source, cam just can't reset, upper bolster and wedge slide block will move downward under the drive of lathe, with the guide plate collision on the cam, gently then damage mould by pressure, heavy then damage pressing equipment, there is very large potential safety hazard.
Therefore, for above deficiency, the utility model provides a kind of rotating cam structure.
Summary of the invention
The technical problem that (one) will solve
The purpose of this utility model is that cam can't reset when solving the cylinder deactivation of existing rotating cam structure, and upper bolster and wedge slide block can move downward under the drive of lathe, bump against with the guide plate on the cam, gently then damage mould by pressure, heavy then damage pressing equipment, there is the problem of potential safety hazard.
(2) technical scheme
For achieving the above object, the utility model proposes a kind of rotating cam structure, this rotating cam structure comprises cylinder, cam chair, cam, guide plate, wedge base and guide wheel, cylinder is connected with cam, cam chair supporting cam wheel, cylinder and wedge base, guide wheel and guide plate are fixed in the same end of cam.
Wherein, described guide wheel is positioned at guide plate one side.
Wherein, described guide wheel comprises connector and roller, and roller is connected with cam by connector.
Wherein, an end of described connector is fixed in cam, and the other end and roller are flexibly connected, and roller can freely rotate on connector.
Wherein, the width of the Width guide plate of the connector of described guide wheel is wide.
Wherein, the length of the Length Ratio guide plate of described guide wheel is long.
Wherein, described connector is connected with roller by bearing pin.
(3) beneficial effect
Technique scheme of the present utility model has following advantage: by having additional guide wheel at cam, when the cylinder return lost efficacy, because guide wheel is provided with roller, the roller of guide wheel contacts with the wedge slide block prior to guide plate, will reset by driving cam like this, slide block and guide plate can not occur and bump against the phenomenon of damaging mould by pressure even damaging pressing equipment, reduced greatly potential safety hazard, avoid the generation of accident, saved cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1: cylinder; 2: cam chair; 3: cam; 4: the wedge slide block; 5: guide plate; 6: the wedge base; 7: connector; 8: roller.
The specific embodiment
Below in conjunction with drawings and Examples the specific embodiment of the present utility model is described in further detail.It is novel that following examples are used for this use of explanation, but be not used for limiting scope of the present utility model.
As shown in Figure 1, the rotating cam structure that the utility model provides, this rotating cam structure comprises cylinder 1, cam chair 2, cam 3, guide plate 5, wedge base 6 and guide wheel, cylinder 1 is connected with cam 3, cam chair 2 supporting cam wheels 3, cylinder 1 and wedge base 6, guide wheel and guide plate 5 are fixed in the same end of cam 3, described guide wheel is positioned at guide plate 5 one sides, guide wheel comprises connector 7 and roller 8, roller 8 is connected with cam 3 by connector 7, one end of connector 7 is fixed in cam 3, and the other end and roller 8 are flexibly connected, and roller 8 can freely rotate on connector 7.The width of the Width guide plate 5 of described connector 7 is wide, and the length of the Length Ratio guide plate 5 of guide wheel is long.Connector 7 is connected with roller 8 by bearing pin or split pin or hinge or other movable connection methods, and the consideration for cost and the composite factor such as safe preferably, connects by bearing pin.
In normal operation, cylinder 1 rotates around fixed axis as power source band moving cam 3, thereby realize the side flanging forming process and send the convenience of pickup, 6 slips of cam 3 and wedge base, guide plate 5 plays the work position-limiting action simultaneously, cam chair 2 supporting cam wheels 3 and cylinder 1 etc., 6 pairs of wedge bases are fixed in 5 position-limiting actions of guide plate of cam 3, help wedge slide block 4 to realize moving back and forth, and guide plate 5 is used for the angle that control cam 3 rotates, make it arrive assigned address, effectively work.
When cylinder 1 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 owing to wedge base 6 is spacing, cam 3 motions put in place, wedge slide block 4 moves downward under the drive of lathe, wedge slide block 4 with move along the inclined-plane after guide plate 5 on being installed in cam 3 contacts, finish flange, after this, wedge slide block 4 moves upward, until separate with counterdie, cylinder stroke arrives top dead-centre, cam 3 backhauls, arrive the precalculated position, then cylinder 1 stroke arrives bottom dead centre, and beginning is circulation next time.And in case lost efficacy as the cylinder 1 of drive source, cam 3 just can't return, and wedge slide block 4 moves downward under the drive of lathe, pushes up with guide plate 5 on the cam 3, gently then damages mould by pressure, and is heavy then damage pressing equipment; Therefore, the utility model has designed guide wheel, when wedge slide block 4 moved downward under lathe drives, wedge slide block 4 contacted with roller 8 on being installed in cam 3, and driving cam 3 rotates, after this, wedge slide block 4 moves along guide plate 5 inclined-planes, and guide plate 5 moves in a circle under the pressure-acting of wedge slide block 4 simultaneously, until contact with wedge base 6, cam 3 motions put in place, and are same when after this motion is with normal condition.
Need to prove that guide wheel includes, but are not limited to use roller, any parts identical or similar with roller structure with rotating function are all applicable.
In sum, by having increased guide wheel, when the cylinder return lost efficacy, because guide wheel is provided with roller, the roller of guide wheel contacts with the wedge slide block prior to guide plate, will reset by driving cam like this, slide block and guide plate can not occur and bump against the phenomenon of damaging mould by pressure even damaging pressing equipment, reduce greatly potential safety hazard, avoided the generation of accident, saved cost.
The above only is a kind of embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
