Description

one

The invention relates to a tool for forging and stamping production.

A cold stamped die stamp containing a coaxially mounted stationary plate connected by columns with a movable top plate, two driving turret disks with mechanisms for loading, unloading and transferring blanks from one disk to another is placed coaxially.

The purpose of the invention is to provide the possibility of processing blanks on disks in different planes.

In the proposed stamp, the mechanism for transferring blanks from one disk to another is made in the form of a lever mounted on the bottom plate with a driving finger attached to it, which is used to push the workpiece along a prism enclosed by side walls, provided for in the mechanism for transferring blanks window for the workpiece, as well as associated with the th with; top plate mounted on the side wall with a receiving window and

{transferring the workpiece from disk to disk of the rotary gate with a guide groove for the drive pin and the receiving cavity open from the side of the side wall and aligned at the extreme upper position of the upper plate with the receiving window, and at the lowest lower position of the upper plate - with the lower disk.

FIG. 1 shows a stamp, type of super xy; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4-mechanism for transferring the workpiece from one disk to another; in fig. 5 is a view along arrow B in FIG. four.

The stamp consists of the bottom plate 1, on which the upper disc 2 is mounted, the slider 3 with the pawl 4, the workpiece transfer mechanism 5 from one disk to another, the stop stops 6, the slider drive 7, the workpiece loading mechanism 8 and parts removal, and the stop 9 for fixing blanks.

Claims (1)

A receiving device 12 is mounted on the upper disk 2 located on the same axis 10 with the lower disk 11. A receiving device 13 is mounted on the lower disk 11. The guide columns 15 and punches 16 are mounted on the upper plate 14 of the punch, and the die 17 is mounted on the bottom plate 1. On the bottom plate of the stamp there is also installed the case 18 of the transfer mechanism of the workpiece, on which the gate is mounted with a cavity of 20, t ha 21, connecting the gate to the top plate, as well as the installation Flax lever 22 with a driving pin 23. A prism 24 is placed in the housing. The driving pin of the lever with one end enters the groove 25 of the gate. The stamp works as follows. The loading mechanism feeds the workpiece to the stop for fixing the workpiece. The top plate feeds the blanks to the receiving device of the top disk. From the top plate, through the drive, slider and dog, the movement is transmitted to the revision disk, which transfers the workpiece to the working area, where it is machined in a vertical plane. From the receiving device of the upper dis, the workpiece falls into the cavity of the gate. When the top plate goes up, the gate through t gu takes horizontal position. and the workpiece rolls from the cavity of the gate onto the prism. When the plate moves downwards, the lever, the pylets of which moves along the slot of the schlumber, delivers the workpiece to the receiving device of the lower disk, which transfers the workpiece to the working area, where it is processed in the horizontal plane. After that, the lower disk transfers the workpiece to the unloading area, where the mechanism removes the finished part from it. Claims for cold pressing, which are arranged coaxially on a fixed bottom plate, connected by columns with a movable top plate, two driving revolver discs with mechanisms for loading, unloading and transferring blanks, from one disc to each other so that, in order to enable processing of workpieces on disks in different planes, the mechanism for transferring workpieces from one disk to another, the goy is designed as a lever mounted on the bottom plate with a fixed on it drive finger, pfiH pushing the workpiece along the guiding prism, provided in the workpiece transfer mechanism, enclosed by side walls: one of which has a receiving window for the workpiece and is connected with the top plate fixed on the side wall with the receiving window and transmitting the workpiece from disk to disk, the gate with a guide groove for the drive pin and the receiving cavity opened from the side of the side wall and aligned at the extreme upper position of the upper plate with the receiving window, and at the extreme lower position of the upper plate - with the lower disk. -F to "a Uqj § "C5
