(54) DEVICE FOR INSTALLATION AND REMOVAL OF STAMPS

one

The invention relates to forging and stamping production, in particular to adaptations intended to install and remove dies from the press table.

A device for mounting and removing dies, containing its 5 connected with the lifting mechanism of the sling and the mechanism for moving the stamp made in the form of two rods 1, is known.

The drawbacks of the device are the necessity of performing a Laz press on a die plate, as well as inconvenience in operation caused by the necessity of manually holding the die on the rods when the die is sliding.

The purpose of the invention is to simplify the design and improve ease of operation.

This goal is achieved by the fact that a device for installing and removing dies, containing straps connected with a lifting device and a die moving mechanism, made in the form of two rods, is equipped with two flexible straps connecting the ends of both rods in pairs, one of the rods is made1; and with lugs for the sling of the lifting mechanism, and the other one is provided with clamps placed on it with the possibility of movement with hanging hooks for the punch. FIG. i shows a device suspended from the crane beam grips with a stamp attached to it; in fig. 2 - the same, at the time of entry into the working area of an open press; in fig. 3 - the same at the time of entry into the working area of a closed press.

Claims (1)

The device for mounting and removing the dies comprises an upper rod 1, which is a rigid steel beam with lugs 2 welded on both sides for hanging using a spreader or a sling 3 on a hook of a lifting mechanism (for example, a crane), the lower bar 4 and connecting the ends of both boom bars 5. At the lower end of one of the bracelets there is a hook 6, with which this brace is removably connected to one of the lower-bar peaks. On the lower rod mounted mobile clamps 7, connected with four grippers 8, hanging from these clamps. The length of the posts should be somewhat greater than the height of the highest press from the table to the top of the bed. When installing the dies on the table of a closed press, a prefix table 9 is attached to the latter if necessary. A device for installing and removing dies works in the following way. On the lower rod 4, the clamps 7 are moved apart to the required distance depending on the dimensions of the punch. By grippers 8, the stamp is hung on the device. With the lugs 2, the device is attached to a gripping device, such as a crane, and thus the stamp is transported to the press. Regulating the lifting height with a lifting device, the stamp is put on the table of the open press, and the stamp on the punch plate is pressed horizontally on the stamp or lower rod 4. After the stamp is installed, the grippers 8 are disengaged from the punch clips and the tool is removed. To place the stamp on the closed press table, the work is carried out as follows. The stamp is transported to the installation site in the same way as in the case of an open press, then the stamp is placed on the table-stand 9, the hook 6 of one of the straps 5 is separated, the lower bar is pushed into the window of the closed press and again connected. with a barbell. Then, lifting it up at a certain height of shtamp, it is inserted into the working area of the press and mounted. Thereafter, the tie rod 5 is disconnected, the lower rod is withdrawn from the closed press window and again connected. The punch is removed from the presses in reverse order. The invention is simple in construction and can be widely applied on presses of both closed and open type. Due to the presence of stashes 5, which provide an easy detachment of the lower rod with a suspended stamp, when force is applied to it, precise positioning of the stamp is greatly simplified. Ease of comfort is also increased due to the possibility of acting not directly on the stamp, but on the rod, which is especially convenient in closed presses with limited access to the stamp. Claims. A device for installing and removing dies, comprising slings associated with a lifting mechanism and a die movement mechanism, made in the form of two shthangs, characterized in that, in order to simplify the design and increase ease of operation, it is equipped with two flexible straps connecting The ends of both rods are pairwise; one of the rods is made with lugs for the sling of the load-lifting mechanism, and the other is provided with clamps placed on it with the possibility of movement with hanging hooks for the punch.
