Abstract

The utility model relates to the driving structure of the terminal press. Wherein, a roller positioning axis is arranged in a machine base above a machine station, one end of the roller locating shaft is jointed with the central axis of a motor, and the other end of the roller locating shaft is provided with an eccentric wheel to make the motor can drive the roller and the eccentric wheel move. When the eccentric wheel is driven to rotate, the eccentric wheel simultaneously drives the slide block which is sleeved on the outside of the eccentric wheel, a punching head is driven to punch up and down, and the detecting device of the optoelectronic inductor which is arranged in the machine base is arranged on the position of an anti-dazzling screen on a roller. The detecting device of the optoelectronic inductor sends the sensing signal through the interdiction, the lighting and the extinguishing of the anti-dazzling screen to control the motor, and corrects the eccentric wheel on the scheduled accurate position. Through the above characteristics, the dynamic force of the motor can directly drive the punching head to punch to form the object. The deficiency of that: the general user needs to make use of the indirect drive of a belt is released. Meanwhile, the loss of the machine parts can be reduced, and the excellent performance of the efficiency and the quality of the punching finished product is effectively raised.

Description

The Drive Structure of terminal press

Technical field

The utility model is relevant for a kind of Drive Structure of terminal press, be meant a kind of originally improvement of its internal works linkage part of type of drive especially at terminal press, direct transmission and driving by power, use the disappearance of adopting belt and flywheel transferring power always and reduce, machinery during with its transmission of effective reduction decreases, and then promotes the efficient of punching out finished product and the superiority of quality.

Background technology

The kind of drive (seeing also Fig. 1) of terminal press commonly used, it mainly is that power with motor 10 is passed to flywheel 12 by belt 11, this roller bearing 13 is turned by flywheel 12 and when carrying out punching press, utilize its inner arrangement of clutch, transmission of power to roller bearing 13, is made these roller bearing 13 drive slide blocks 14 and drift 15 reach the punching press object, and finishes in the action of punching press each time, utilize brake gear 16, it is limited to fixes the position in advance and treat next time action; But with regard to the aforesaid kind of drive, be that the mode that the power of motor 10 is adopted indirect drive through belt 11 and flywheel 12 is passed to roller bearing 13, easy speech, this belt sleeve is loaded between motor 10 and the flywheel 12, its in suit in conjunction with the time must keep certain degree of tightness nargin to buckle friction, so could allow motor 10 when starting, can rotate simultaneously by interlock belt 11, if belt 11 is pine or too tight too, then can skid and maybe can't turn, even produce the problem of fracture when turning, because of belt 11 can produce abrasion in use for some time,, turn usefulness and prolong its life-span again to guarantee it so the user needs regularly to adjust its nargin; Other is the person, with regard to the aforementioned indirect drive mode of adopting, because belt 11 is a standard specification and needs the certain degree of tightness nargin of maintenance, therefore its horsepower and torsion that can mate the motor 10 that uses has its limit, rotating speed to motor 10 also has its restriction simultaneously, trace it to its cause is when being to use high-power or high-revolving motor 10, moment torsion when it starts tends to surmount 11 of belts and can load, therefore vertical if motor manufacturing technology day crescent benefit, horsepower and rotating speed also constantly promote, use can't is competent at and mate to this transmission mechanism also, and causing the punching press object has its restriction and can't promote its efficient and the quality of its shaped article of lifting, and Gu Qiduo has the system elbow; Moreover, because the certain degree of tightness nargin of belt 11 tools, therefore finish and when desiring to carry out next stamping press in the action of punching press each time as the user, though motor 10 has stopped power output, flywheel 12 still can give drive roller bearing 13 and makes its deflection one angle slightly because of rotator inertia continues; Cause drift 15 can't be positioned in former accurate position of establishing, and cause operation precision deficiency and badly influence the moulding quality of object, cause the generation disqualification rate; Moreover, in the aforementioned transmission mechanism, this arrangement of clutch and brake gear 16, be to utilize plural dowel 16a and sleeve 16b, and block 16c and fixture block 16d with clip breach finish clutch and brake, therefore when the keying of stamping press, can send sizable noise, and cause user's discomfort, in view of above-listed deficiency, truly have necessity of improvement.

The utility model content

Main purpose of the present utility model provides a kind of Drive Structure of terminal press, wherein this motor directly drives roller bearing, drive slide block and activate drift by roller bearing again, and then finish stamping press, need not rely on belt for support because of it and make indirect drive like the dust head, so the consume of the power in the time of reducing its transmission, and can obtain more complete and more efficient horsepower output; Again, this adopts the mode of direct driving roller bearing, because no belt comes indirect drive as medium, so can not produce the gap nargin that abrasion also need not regularly to adjust belt, the utility model can be according to user's setting or demand simultaneously, adopt the motor of coupling to come device to use, and then reach the most excellent driving and transmission usefulness, also can satisfy the requirement of the different objects of punching press and its shaping efficiency certainly.

An of the present utility model purpose provides a kind of Drive Structure of terminal press, motor driven roller bearing and drive slide block and drift is synchronized with the movement wherein, so the user punching press finish and with motor when stopping operating, because its unpowered output, this roller bearing also Yin Mada brakes and stops immediately, makes this slide block and drift can not produce inertia deflection whereby, allows the precision of stamping press significantly promote, the user can accurately control its program, and then improves the quality of object moulding.

Another purpose of the present utility model provides a kind of Drive Structure of terminal press, wherein this adopts direct transmission person, except that significantly reducing members such as its transmission, clutch and brake, it turns all is located in the support with transmission mechanism, noise in the time of can significantly reducing its transmission or keying, the quiet kilsyth basalt of tool the best is existing.

A purpose more of the present utility model provides a kind of Drive Structure of terminal press, wherein but this is located at the anti-dazzling screen position of photoelectric sensor arrangement for detecting on roller bearing in the support, and pass through its induced signal control motor when initiating task, drift is proofreaied and correct in predetermined accurate position, significantly promoted the superiority of the precision and the finished product of stamping press.

For achieving the above object, the utility model provides a kind of Drive Structure of terminal press, it is characterized in that, locating shaft is located in the support of board top behind this roller bearing, the axle butt joint of one end and motor, the other end is to have an eccentric wheel, the eccentric outside is set with a slide block, make motor can drive roller bearing and wobbler action, when eccentric wheel turns is to drive slide block simultaneously, and on the interlock drift carries out, following punching press, and in this photoelectric sensor location support, make the anti-dazzling screen position of its arrangement for detecting on roller bearing, and proofread and correct in predetermined accurate position by its induced signal control motor and with eccentric sedan-chair.
