Abstract

The utility model provides a novel guillotine shear. The structure of the utility model consists of a motor, a retarding mechanism, eccenters, an eccentric shell, a cam, a connecting rod and a tool post. The working principle is that the motor drives the retarding mechanism to make the tool post have up and down reciprocating shear movement through left and right eccenters and the eccentric connecting rod on a transmission shaft. The shear movement can be controlled by the cam and a near switch.

Description

Novel plate shearing machine

Affiliated technical field

The utility model relates to a kind of equipment of metal blank being sheared processing.

Background technology

At present, known plate shearing machine generally is made up of motor, reducing gear, eccentric wheel, eccentric ratio, clutch, knife rest.Action by revolving meber clutch or the cutter of stopping control shearing.Its shortcoming: produce, make cumbersome, difficulty, number of drawbacks such as part is fragile, maintenance is inconvenient, cost cost height are installed.

Summary of the invention

In order to overcome existing a series of problems of existing plate shearing machine and defective, the utility model shear lathe provides a kind of novel plate shearing machine of using cam and controlling shear action near switch.Not only overcome the above shortcoming of existing plate shearing machine, and safe, reliable, power saving.

The technical scheme that its technical problem that solves the utility model adopts is: a cam is set on the power transmission shaft of plate shearing machine, and the cam top is established one near switch, the shear action of control plate shearing machine.Electric motor starting, the cam that drives on the power transmission shaft is rotated near in the switch control range time by original position, near switch motion, cut off general supply, motor quits work, and this moment, power transmission shaft rotated a circle, and cam is got back to original position, drive upper tool post and finish once stroke up and down, promptly realize shear action one time.

The beneficial effects of the utility model are, by near switch and cam motor directly being controlled, finish shear history, and are simple in structure.

Description of drawings

Embodiment further specifies the utility model below in conjunction with accompanying drawing:

Fig. 1 is a fundamental diagram of the present utility model.

Fig. 2 is the sectional structural map near switch and power transmission shaft overhead cam that novel plate shearing machine is installed.

Fig. 3 is the residing original position schematic diagram of the cam on the plate shearing machine power transmission shaft.

The specific embodiment

Among Fig. 11, motor 2, reducing gear 3, power transmission shaft 4 left eccentric wheels 5, right eccentric wheel 6, cam 7, near switch 8, left avertence heart connecting rod 9, right avertence heart connecting rod 10, knife rest

In embodiment illustrated in fig. 1, novel plate shearing machine is gone up left and right eccentric wheel (4,5) by motor (1) driving reducing gear (2) by power transmission shaft (3) and is driven left and right eccentric ratio (8,9), makes the upper and lower reciprocal shear action of knife rest (10).Its shear action is by cam (6), control near switch (7).

In embodiment illustrated in fig. 2, cam (6) is fixed on the power transmission shaft (3) by flat strong (11) and back-up ring (12).When cam (6) rotates a circle, form one time shear action.

Fig. 3 is the left view of Fig. 2.

Claims (2)

1. novel plate shearing machine in running part, cam, is installed near switching sequence, it is characterized in that: transmission axle head fixed installation cam is fixed near the cam near switch.

2. novel plate shearing machine according to claim 1 is characterized in that: cam with install near switching sequence, its cam with keep the gap to be provided with near the switch control zone.
