SU364397A1 - DEVICE FOR UNEMBREEDABLE CUTTING OF SHEET - Google Patents

Description

one

The invention relates to the processing of metals by pressure, in particular to devices for non-shear cutting of sheet material, preferably on guillotine shears.

Devices for non-seam cutting of sheet material are predominantly used on guillotine shears, containing a limiting resettable stop and a platform, in which mutually perpendicular grooves are located the clamps associated with the drives of their reciprocating movement.

The purpose of the invention is to provide cutting sheet at a given angle.

For this, the platform is made rotatable around an axis located at the intersection of a plane parallel to the cutting plane and a plane passing through the bearing surface of the clamping abutment with which the platform is provided. In the slots of the platform, parallel to the support surface of the base stop, there is a restrictive stop that interacts with the grips located in these slots.

FIG. 1 shows the proposed device, a plan view; in fig. 2 is a section along A-A in FIG. I; in fig. 3 is a section along BB in FIG. one.

The device contains a platform / associated with the production of its rotation to a given

the angle around the axis 2. On the platform there is a basing stop 3, whose support surface 4 passes through the axis of rotation of the platform. Parallel to the supporting surface of the base stop, grooves 5 are made in the grooves. In the grooves there are grips 6 and adjustable stop stop 7. In addition, the platform has grooves 8, the direction of which is perpendicular to the direction of the grooves 5. In the grooves 8 there are grippers I connected to the drive 10 their returnable movement. The grippers 6 are also provided with a drive // of reciprocating movement.

The device works as follows.

In the initial polishing, the device is configured to process the specified part. The platform / is rotated to a predetermined angle a, and the stops 7 are set at a predetermined distance from the axis 2. The store 12 with the workpieces 13 is mounted on the platform L The grippers 6 and 9 are in their extreme rear position.

On command from the control panel, the grippers 9 are driven, the first billet is withdrawn from the magazine, and it is based on the stop 3. After completion of the workpiece base, the actuator 11 is turned on and the grippers 6 are set in motion. The grippers 6 contact their support surface with their billet and clamp her own lips. Simultaneously with the actuation of the grippers 6, a command is given to retract the grippers-pushers 9 to the initial position. As the grippers pushers under the magazine 12 pass, they are recessed by the next billet, which is lowered into place of the previous one. The grippers 6 continue their movement up to the stop 7, sending the workpiece to the cutting zone by a specified amount. After stopping the grippers 6, a command is issued to cut. Upon completion of the cut, a command is issued to expand the grippers 6 and return them to their original position.

The cycle of operation of the device ends there. The command to repeat the cycle is given. When sending the next billet, the jipe blows the part into the special container (not shown) that collects the machined parts.

Subject invention

A device for dimensionless cutting of sheet material, mainly on guillotine shears, containing a restrictive resetting stop and a platform, in which mutually perpendicular grooves are clamps connected to the drives of their reciprocating movement, characterized in that, in order to cut the sheet under given angle, the platform is made rotatable around an axis located at the intersection of a plane parallel to the plane of cut, and

the plane passing through the bearing surface of the clamping support, which the platform is provided with, and in the slots of the platform parallel to the mounting surface of the clamping support, the mentioned restrictive support is placed,

interacting with the grips located in these slots.
