Description

Stamps are known for making cone vessels (forms) with corrugated walls from sheet blanks.

The described stamp differs from the known ones in that it is made in the form of two discs on which the rotary rods interacting with fixed crown supports mounted on the press table are radially fixed, one of the discs (upper) being attached to the press ram on the Rod carrying the disk buffer (e.g., spring-loaded) retaining rod in the plane of the disk, and the other disk (lower) rests on a buffer located in the lower part of the bed (in the table) of the press.

Such an embodiment of the stamp permits the manufacture of deep vessels used for baking bread in one stroke of the press without pre-stretching.

FIG. 1 shows the scheme of the proposed stamp with a partial cut; in fig. 2-diagram nest pr: and making forms in the longitudinal and transverse sections.

The stamp is made in the form of a hinge-finger press consisting of the following main parts: slot, node, lower disk and node of the upper disk. The nest consists of external and internal cylinders / and 2, which are fixed to four supports 3. The upper end of the external cylinder is made in the form of grooves in which fingers 4 are placed. The upper end of the internal cylinder is also made in the form of grooves in which fingers 4 lie press work.

The node of the upper disk consists of its own disk 5, to which radial fingers 6 are pivotally attached along the rim; stem 7; springs 8, plate-shaped disk 9; spring adjusting devices 10; rocker 11; guide sleeve 12; guide sliders / i, t g M and eccentric 15 № 1475632 - The lower disc node consists of its own disk 16, to which radial pins 4 are hingedly attached to the rim; stock / 7; springs / s; guide pins -19 and 20. To stop the electric motor after the mold has been manufactured, a limit switch 21 is attached to the guide sliders 13.

The blank, which is a circle of glossy iron, is placed on the fingers 4 of the lower disk 16. When the electric motor is turned on, the sprocket and the Gall circuit are transmitted to an asterisk 22, then to the shaft 23 and eccentrics 15. While rotating the eccentrics, the glands 14 reciprocate together with the rod 7, the yoke 11 is carried along with it, which moves in the sliders 13. When moving downward, the rod 7 moves the disk 5 and the plate-shaped disk 9 with the help of spring 8 after the upper disk 5 comes together with the lower disk / 5 edaets on the lower disc, which starts with the workpiece to move downward. As such, the spring 18 is compressed. When the discs 16 and 5 move downward, the fingers 4, resting on the outer cylinder 1, will begin to rotate on their hinges. In this case, the disk-shaped disk 9 will be pressed up by the fingers 6, compressing the spring 8.

Upon further movement, the lower legs 4 (Fig. 2) of the lower disk begin to slide along the grooves of the inner cylinder 2, continuing to rotate around their joints and compress the workpiece 24 towards the center of the disk. On the fingers 6 of the upper disc 5, a plate-shaped disc 9 presses, which expands the workpiece from the center of the disc. Under the action of these forces, the workpiece takes a corrugated shape.

When tg 14 moves upward, the rocker arm // together with the rod 7, the disk 5 rises and under the action of the spring 8, the fingers 6 are released and slide along the plate-shaped disk 9, assuming the initial position. The disk 16 is pushed up by the action of the spring 18 and returns to its original position.

The Central Scientific Research Institute of Baking Industry notes the usefulness of the proposed stamp for making corrugated forms.

Subject invention

A stamp for manufacturing cone vessels (forms) with corrugated walls from sheet blanks, characterized in that, in order to manufacture deep vessels for an odd press stroke by bending without pre-stretching, it is made in the form of two discs on which rotary rods are radially fixed, interacting with fixed crown supports mounted on the press table, one of the disks (upper) attached to the slider inpecca on the rod carrying the disk buffer (for example, spring), holding the rod in the plane the disk and the other disk (lower) rests on a buffer located in the lower part of the bed (in the table) of the press.
