Abstract
The utility model discloses a grooved cam punching press mechanism, including a driving part and a follower, the driving part includes a camshaft, a bracing strut that is used for the stationary cam axle, the tip of camshaft is the circular shape, sets up oval -shaped flute profile at its tip and becomes the recess, set up a cam roller in the recess, cam roller rolls in the recess, cam roller connects the follower, the follower includes a push rod, the drift of a punching press work piece and the sleeve of restraint drift motion, the push rod includes a straight -bar, the straight -bar upper end sets up a horizontal pole that is used for connecting cam roller perpendicularly, the drift is connected to the straight -bar lower extreme, the sleeve encircles and sets up on the drift. The utility model discloses simple structure is compact, and easy operation is convenient. Its speed curve and accelerating curve all in succession and do not have the sudden change, so not only do not have the rigid shock but also do not have the soft shock to effectively reduce shock and vibration and noise, increase of service life.
Description
Technical field
The utility model relates to a kind of grooved cam punching mechanism, belongs to field of mechanical technique.
Background technology
Pressing equipment is one of important component part of industrial equipment, all plays an important role in all trades and professions.Especially in terms of auto manufacturing and mechano-electronic components and parts, the part of Sheet Metal Forming Technology manufacture has accounted for the biggest proportion.The advantages such as in process of production, Sheet Metal Forming Technology has saving material and the energy than traditional machining, and efficiency is high, and more mold exchange is convenient.It may be said that stamping products is seen everywhere, the life with us contacts more and more closer.Therefore the precision of pressing equipment, efficiency, the quality living standard important in inhibiting to improving people are improved.The main transmission of existing pressing equipment uses toggle more, can only meet the movement needs of limited input and output, and to take bigger space.The biggest noise and vibration can be produced during punching press simultaneously.If using cam mechanism, easily realizing various input and output movement needs, and mechanism size is compact.Resetting for push rod and use back-moving spring more, long reciprocating motion can cause spring fatigue to destroy, it is therefore desirable to often changes.
Utility model content
In order to overcome above-mentioned deficiency, the utility model, for defect of the prior art, uses a kind of grooved cam punching mechanism, thus reduces noise, increases the service life.The technical solution of the utility model is as follows:
A kind of grooved cam punching mechanism, including a driving link and a driven member, described driving link includes a camshaft, one for fixing the bracing strut of camshaft, the end of described camshaft is circular, offering an oval groove in its end and form groove, arrange a cam bawl in described groove, cam bawl rolls in groove；Described cam bawl connects driven member, described driven member includes a push rod, the drift of one stamped workpieces and the sleeve of constraint drift motion, described push rod includes a straight-bar, described straight-bar upper end is vertically arranged one for the cross bar connecting cam bawl, described straight-bar lower end connects drift, and described sleeve is circumferentially positioned on drift.
Above-mentioned cam bawl is a cylinder, and cylindrical axle center is offered a post holes, and the cross bar for push rod inserts.
The beneficial effect that the utility model is reached:
The design of grooved cam punching mechanism is simple and compact for structure, simple to operation；Cam profile curve is made groove, roller is placed in groove, rely on the contour curve of groove both sides to make driven member remain contact.Substituting back-moving spring and realize push rod reciprocating motion, the fatigue rupture that can be prevented effectively from back-moving spring increases the service life；Cam follower motion rule selects 3-4-5 order polynomial, and its rate curve and accelerating curve are all continuously and without sudden change, therefore not only without rigid shock but also without soft impulse, thus effectively reduces impact shock and noise, increases the service life.

Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of Fig. 1 convexity wheel shaft；
Fig. 3 is the structural representation of push rod；
Fig. 4 is the structural representation of cam bawl.
Detailed description of the invention
Below in conjunction with the accompanying drawings the utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of grooved cam punching mechanism, including a driving link and a driven member, described driving link includes a camshaft 2, one for fixing the bracing strut 1 of camshaft, the end of described camshaft 2 is circular, offers an oval groove in its end and forms groove 7, arranging a cam bawl 3 in described groove 7, cam bawl 3 rolls in groove 7；Described cam bawl 3 connects driven member, described driven member includes a push rod 4, the drift 5 of one stamped workpieces and the sleeve 6 of constraint drift motion, described push rod 4 includes a straight-bar 41, described straight-bar 41 upper end is vertically arranged one for the cross bar 42 connecting cam bawl 3, described straight-bar 41 lower end connects drift 5, and described sleeve 6 is circumferentially positioned on drift 5.
As shown in Figure 4, above-mentioned cam bawl 3 is a cylinder, and cylindrical axle center is offered a post holes 31, and the cross bar 42 for push rod 4 inserts.
The course of work of the utility model grooved cam punching mechanism is: first drive shaft be connected on camshaft 2, workpiece to be processed is placed on corresponding station, camshaft 2 rotates after driving, the cam bawl 3 that the cross bar 42 of push rod 4 connects is placed in groove 7, the contour curve relying on groove 7 both sides makes push rod 4 remain with camshaft 2 to contact, cam drives push rod 4 to pump by roller 3, and push rod drives drift 5 to perform punching operation.After a rise terminates, drift departs from corresponding station, and now the workpiece machined is taken out by operating personnel.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from the utility model know-why; can also make some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
