Description

one

The proposed device can be used to handle pipes and sheets and to connect the nozzles to the pipes.

The prior art devices for cut-outs of holes, containing a pipe rotation assembly mounted on a frame and a cutter, kinematically connected with a cam, are difficult to set up when cutting openings of different diameters.

Simplified settings for cutting openings of different diameters are ensured by the fact that in the proposed device the kinematic connection of the cutter with the cam is made using two rocker arms mounted on the frame with the possibility of rotation and movement and interconnected levers by means of sliders located at the ends of rocker arms and carriers, respectively, cutter and a pulley, while the relative length of the levers is equal to the ratio of the arms of the rocker arms.

Pa figs. 1 shows the kinematic diagram of the device;

in fig. 2 - the same view in the place;

FIG. 3 is a section along A-A in FIG. 2

The device comprises a support frame /, a rack 2 on which the lower 3 and upper / rocker arms are movably mounted. Pa koromysle 3 also slides the sliders 5 and 6, which are connected hingedly with the yoke 4 by levers 7 and 8, and the pa slide 5 is mounted worker

The organ 9, in the slider 6, is mounted a drive motor 10 rotating through a gear // copy roller 12, which is magnetized by an electromagnet 13. The roller 12 is in constant contact with a cam 14, having a cross-section shape of the inlet nozzle. The copier is mounted with a bracket 15, having a variable effective length and attached to a rack 2.

Rack 2 can be installed by a node angle

the intersection of the pipe and pipe. The angle is measured by the angle with the scale 16 and the pointer 17. With the help of the nut 18, the stand 2 sec connection is relaxed and secured.

The base 19 is made in the form of a pipe with a screw terminal 20. To be machined, the pipe 21 or sheet 22 is laid on a rack 23 with rollers 24.

The device works as follows.

The pipe in which the hole is cut is laid down by the rollers. The base is set to the required height. The stand is secured by the node by the angle of intersection of the axes of the inserted pipe and the pipe. The copier is mounted on a bracket at a predetermined distance from the axis of the rack. Levers of appropriate length are attached to the yoke on the slider. The copy roller is applied to the copier and an electric plug is turned on. After turning on the engine copier

roller roll copier. Sliders slide along

rocker, which rotates around the axis of the rack at an appropriate angle. The tool body cuts holes in the pipe along the interface of the pipe and pipe. To cut a series of holes without rearrangement of the pipe, the mounting bracket of the copier is turned at a certain angle or the rearranging of the copier, changing the effective length of the bracket.

When cutting holes in sheets, the latter are laid on a rack.

The subject of the invention is a device for cutting openings containing a mounted rotary assembly of a pipe rotation unit and a cutter, kinematically associated with a copier, characterized in that, in order to simplify adjustment when cutting openings of different diameters, the kinematic connection of the cutter with a copier is made using two rockers installed on the ra. me. with a possible; the bones of rotation and movement and interconnected levers by means of the nOvtiy-iTOR, located on the ends of one of the wrinkles and carrying, respectively, the cutter and the kbMrny roller, while the ratio of lengths and levers is equal to the ratio of arm arms.
