Description

one

This invention relates to the field of metal forming, more precisely, to a pressing tool.

A known press matrix assembly for producing profiles comprising, in series, mounted on a base plate in separate blocks having the possibility of reciprocal axial movement, a main and auxiliary matrix.

The disadvantages of the known matrix block are the need for a significant container stroke to ensure passage of the saw when cutting a press product and lifting the additional matrix block while removing the pressure rod, as well as the need for significant displacements of the matrix blocks, which leads to an increase in the duration of the total pressing cycle.

In the proposed matrix node, these drawbacks are eliminated and the node provides for cutting a press product behind the main matrix without withdrawing the container and matrix blocks, and removing the press residue from the main matrix is accomplished by removing the block of this matrix from the additional matrix block. At the same time, the duration of the overall pressing cycle is shortened due to the fact that in the base plate an enveloping product is made along the entire height, called the one coming out of one of the plate ends, and the latter is fitted with a fixed

from the side of the other end of the drive, the return and translational movement along the plane, which is the right axis of the press.

FIG. 1 shows the matrix assembly at the final pressing time; in fig. 2 - matrix node at the time of removal of the press residue from the main matrix; in fig. 3 is a matrix assembly at the time the press product is separated from the press residue.

The matrix node (Fig. 1) contains two blocks: block 1 of the main matrix and block 2 of an additional matrix located in front of it. In block 1, the holder 3 is placed with the main matrix 4 and delivery 5. In block 2

Additional matrix 6 is placed, which joins with container 7. Cross section 5 is installed on plate 8 with a drive. The plate 8 rests on the front traverse of the press. Drive provides transverse relative

Axis press moving plate.

The drive of block 1 ensures its removal from block 2 and return to the initial position. Behind the matrix assembly is a saw 9 driven to separate the press product from

press residue (Fig. 3).

The matrix node works as follows.

During the pressing process (Fig. 1), the blank placed in the container 7 under the action of

punch 10 n press washer 11 is extruded

through the main matrix 4. At the end of the extrusion, the under-pressed part of the workpiece is completely displaced from the container 7 to the point of the additional matrix 6. Then the working pressure is removed from the punch 10 and the container 7 is unloaded from the pressing force. Plate 8 is driven away from the pressing axis by means of an actuator (FNG. 2). The free movement of the plate 8 without deformation of the press article 12 is ensured by the presence in it over the entire height of the surrounding product. groove. A saw 9 is formed in the space formed behind the spacer 5, and the press article 12 is separated from the pressost 13 behind the main die. The press article is removed from the matrix assembly. Saw 9 is retracted. Then, with the help of the nrivod, block 1 with the main matrix 4 is retracted from block 2 (Fig. 3). At the same time, the press residue 13 with its conic thickening is held in the additional matrix 6, and the smallpox matrix 4 is freed from the profile part of the press residue. In the process of removal of the press residue, block 2 with the additional matrix 6 remains stationary. Then, an additional matrix 6 with a press residue 13 is removed from block 2. This can occur either in an auxiliary position (for example, when block 2 is designed as a turret) or on a press axis. In the latter case, more is required.

Copteinsra move. The removal of the press residue 13 from the additional matrix 6 is carried out outside the press and, in view of the simple form of the point of the additional matrix, it is not difficult.

After installation, in block 2, the additional matrix 6 freed from the press residue is transferred to the pressing axis. Then, block 1 with the main matrix 4 is lifted, plate 8 is shifted onto the pressing axis and container 7 is pressed against the additional matrix 6. The matrix node is ready for the next pressing.

Subject invention

The matrix node of the press for the manufacture of the profile, containing successively mounted on the base plate in separate blocks, the possibility of mutual axial movement, the main matrix and the final matrix 0, which is necessary to reduce the total the recovery cycle due to the umepshep of the container's movement and displacement of the matrix blocks, in the 01 plate, 1e runs across the entire height, covering the product's groove, outputs displacements of P1 1loskosti, per epdikul rpoy axis of the press.
