Description

Automatic stapling machines equipped with continuous feed mechanisms, straightening, bending and cutting of the workpiece are known.

Feature described

the machine is its ability to produce staples with a sharp end and a pierced end.

The described machine consists of the following units: bed, mechanism for bending, cutting and brushing of the brackets, drive shaft and feed mechanism.

Inclined sliders for the sliders, a cutting mechanism and staples are mounted on the frame. In the middle part of the bed there is a stamp for bending staples. At the bottom of the machine there is an electric motor of the pedal for turning on the machine.

The mechanism of bending, cutting, and slewing consists of guides, sliders, actuator, gearbox, replaceable tool and knives. Sliders are moving in guides located to the vertical at an angle of 15 °. Sliders are driven through cylindrical

gears. During the course of the sliders down, a discrete tool bends the staples to the size of the mandrel and simultaneously cuts the metal by layers. Erschenne produced at the end of the stroke of the slide with special scissors.

The drive shaft is mounted in two sliding sliding supports in the upper part of the bed. On the shaft there is a brush and a flywheel. The gears are constantly meshed with the bevel gear. The flywheel serves to reduce unevenness during bending and cutting.

The feed mechanism and straightening of the frame to the mechanism are flexible, and the bar lengths of the required length are designed as an independent unit with an individual drive. The adjustment of the mechanism to a specific bar length is done by interchangeable gears. The bar is edited with right rollers.

When the machine is in operation, both ends of the cut bar are bent by two sliders set at an angle of 15 ° to the vertical. The sharp and sharp ends of the staples are made by special cutters placed in two sliders.

Subject invention

An automatic machine for the manufacture of building brackets, equipped with mechanisms for continuous feeding, straightening, bending and cutting of the workpiece, differs from Hj, and with the fact that, simultaneously with the flexible brace, also sharpening and finishing its ends, the bending mechanism is designed as bending pads, unrestricted in the guides, inclined to the average non-bending of the Moii part of the bracket at the angle of the point of its ends and provided with scissors.
