Abstract

A cutting machine includes gear box (2) and power takeoff shaft (5) therein. It is characterized in that: the terminal of the power takeoff shaft disposes internal pressure plate (6), inner attrition piece (7), cutting piece (8), external attrition piece (9), external pressure plate (10) and elastic hold-down piece (11) in turn through clamp nuts. The internal pressure plate (6) the external pressure plate (10) is connected with the power takeoff shaft (5) in the way of key connection. The inner attrition piece (7), the cutting piece (8) and the external attrition piece (9) is assembled on the power takeoff shaft (5) in the way of movable fit. When the stress of the cutting piece of the utility model is too high and overload, slipping phenomenon can be generated between the internal, external attrition pieces and internal, external pressure plates, which can protect electric motor and prevent the cutting piece from breaking.

Description

A kind of cutting machine

(1) technical field

The utility model relates to a kind of metal material cutting equipment, particularly a kind of cutting machine.

(2) background technology

Mostly the cutting machine of prior art is to adopt belt pulley as driving member, by the driving belt drive installation cutting work of the line shaft realization of cutting blade to metal rod is arranged.Because due to the self structure of band, wheel transmission, it is big and lose fast phenomenon often to exist transmitted power consumption in cutting process.In addition; when cutting blade in the rotation cutting process if during prominent being hit; because no overload protection (is protected drive motors if rely on skidding of belt pulley; because belt tension is difficult for accurately grasping; reliability is relatively poor); not only very easily burn out the motor accident, and in operating process, the incident that causes the cutting blade fragmentation to be hurted sb.'s feelings because of misoperation happens occasionally also.

(3) summary of the invention

The purpose of this utility model provides a kind of can by automatically skid solve the cutting machine of overload protection problem by gear drive as driving mechanism and when its cutting blade is in overload condition with regard to being to overcome above-mentioned weak point of the prior art.

The purpose of this utility model can realize by following measure:

Cutting machine of the present utility model comprises the power output shaft that is installed in the gear-box, by clamp nut interior platen, interior friction plate, cutting blade, outside friction disc, external pressure plate and elastic pressed piece is installed successively at the shaft end of described power output shaft; Platen all is connected with power output shaft by the key ways of connecting with external pressure plate in described; Described interior friction plate, cutting blade and outside friction disc are sleeved on power output shaft in mode movingly.

Elastic pressed piece described in the utility model is a spring.

Cutting machine of the present utility model in use can elastic pressed piece---the thrust of spring keeps internal platen, interior friction plate, cutting blade, outside friction disc and external pressure plate to produce constant chucking power by regulating; when cutting blade during because of stressed excessive the overload; " skidding " phenomenon be will produce between the inside and outside relatively platen of inside and outside friction plate, protection motor and the effect that prevents the cutting blade fragmentation played.In addition because the utility model changes the pulley transmission mechanism of prior art is gear drive, also fundamentally having solved prior art, often to exist transmitted power consumption in cutting process big and lose fast problem.

(4) description of drawings

Accompanying drawing is a front view of the present utility model.

(5) specific embodiment

The utility model is further described below with reference to embodiment (accompanying drawing):

As shown in the figure, cutting machine of the present utility model comprises installation motor 1, the gear-box 2 that combines with motor 1 and is installed in the power output shafts 5 that driven by

gear

3,4 in the gear-box 2; Platen 6, interior friction plate 7, cutting blade 8, outside friction disc 9, external pressure plate 10 and spring 11 in the shaft end of described power output shaft 5 is equipped with successively by clamp nut 12; Platen 6 all is connected with power output shaft 5 by the key ways of connecting with external pressure plate 10 in described; Described interior friction plate 7, cutting blade 8 and outside friction disc 9 are sleeved on power output shaft 5 in mode movingly.

Claims

1, a kind of cutting machine, it comprises the power output shaft (5) that is installed in the gear-box (2), and it is characterized in that: the shaft end at described power output shaft (5) is equipped with interior platen (6), interior friction plate (7), cutting blade (8), outside friction disc (9), external pressure plate (10) and elastic pressed piece (11) successively by clamp nut (12); Platen (6) all is connected with power output shaft (5) by the key ways of connecting with external pressure plate (10) in described; Described interior friction plate (7), cutting blade (8) and outside friction disc (9) are sleeved on power output shaft (5) in mode movingly.

2, cutting machine according to claim 1 is characterized in that: described elastic pressed piece (11) is a spring.
