(54) DEVICE FOR THE DAILY PREPARATION OF PREPARATIONS

one

The invention relates to equipment, dp of production of brake sub-socks and can be used, for example, in the manufacture of asbestos technical products.

A device is known for the piece-by-piece delivery of blanks to a treatment zone, containing stores of blanks installed on the frame and a cutter connected to the turntable with a window for issuing blanks and support plates ll.

However, this device is intended for. single delivery only flat blanks and does not allow delivery of blanks of complex configuration, for example, metal frames of brake shoes to the DT-75 tractor.

The proposed invention eliminates the noted disadvantage due to the fact that the device is provided with fixedly mounted on the cutter and overlying part of the windows stops with bevels, orienting the workpiece, and pivotally fixed in each of the stores with levers that contact the working stroke with the workpiece, and during reverse Progress - with a gadget.

FIG. 1 shows a top view of a device for simultaneously issuing two blanks; FIG. 2 .- section A-A of FIG. one.

A device for routine delivery of blanks is installed above the table 1 of the turret press at the center of the molds 2 on the bracket 3, rigidly connected with the press frame, and consists of two stores 4 rigidly interconnected, the cross-section of which is made according to the shape of the foot of the blanks 5. In the lower part of the shops 4 there is a cut-off 6, made in the form of a sector with windows for dispensing blanks and movably connected to the axis 7 of the press foot. Section 6 and the workpieces in stores 4 rest on plates 8 rigidly connected to shops 4. To communicate oscillating movement to the cutter 6, synchronous to the movement of the table of the turret press, serves as a lever 9, a ball connected to the cutter 6, the bracket 3 and the 1O swivel mechanism backgrounds 1.

In order to ensure smooth delivery and precise orientation of workpieces having a radius of curvature and slightly different in size from the sizes of the nests of the molds, the cutter 6 is equipped with supporting workpieces by stops 11 with bevels, and the magazine 4 is hinged on them by levers 12 and stoppers 13,

The device works as follows

When the press table is moved counterclockwise, the lever 9 sets in motion the cut-off device 6, which captures 4 lower blanks from the stores. After ™, the blowing blanks are held in magazines 13 by the constraints 13. When moving, cut 6, the blanks are held in its windows by bevels of the stops 11 and levers 12, preventing their displacement relative to the nests of the molds.

When the press reaches the initial position, the blanks are moved by the cutter 6 beyond the limits of the support plates 8 and the levers 12 are placed into the nests of the pre-molds. When aeg; the levers 12 orient the blanks in the nests, pressing them at an angle to the back walls of the molds.

When the cutter moves to its initial position, the levers 12 are raised by it and release the blanks, which, under the action of their own weight and inclined

the bottom surfaces of the lugs 11 are horizontal. On the surface of the molds, the workpieces are held by the lugs 14 in them. In the case of blanks falling on the front edge of the nests of the molds, the lugs 11 of the lower protuberance (

Billets are sent to the KOHe4HoJ position with a large part.

A device for the issuance of blanks permits to mechanize the operation of placing the frame of the personal brake pad frames to the DT-75 tractor into the nests of the molds of the turret press and significantly increase the productivity of the operation of the molding of brake pad briquettes.
