Abstract

The invention relates to equipment for the manufacture of ring forge forging and improves the quality of the products. For this, a device for turning the workpiece on a fixed mandrel has a mechanism for centering the workpiece, one of the rollers of which is connected to a drive for turning to the step of turning. The exclusion of the workpiece swivel on the mandrel improves the accuracy of the angular pitch of turning. 1 il.

Description

The invention relates to the processing of metals by pressure, in particular to devices for the supply of billets and bandages for forging bar on a mandrel.

The purpose of the invention is to improve the quality of products by increasing the accuracy of the angular pitch of the workpiece by eliminating its swing on a non-driven mandrel.

The drawing shows the structural scheme of the device for turning over.

The device for kaytovka ring blanks with forging rolling on the mandrel contains a pressure element 1, the support element 2 with the means for its fastening on the slide 3 of the press and the connecting link 4, pivotally connected by the support and pressure elements. The additional pressure element 5 is installed with the possibility of interaction with the pressure element 1 through the workpiece 6. The additional connecting link 7 is articulated; - with support and additional pressure element 5. The device contains a drive 8 of synchronous movement of both connecting links. The pressure elements are made in the form of rollers, one of which is made of a Nm drive. Both connecting links 4 and 7 are made in the form of one-arm levers, and the pressure elements 1 and 5 are installed at the ends of these levers. The actuator 8 of synchronous movement of both connecting links is implemented in the form of a rack mechanism and a pneumatic cylinder. The device works as follows.

The workpiece 6 is mounted on the fixed mandrel 9. After the strike of the press 10 is given a command to rotate the workpiece 6 on the mandrel 9. The drive pneumatic cylinder 8 is turned on.

gov (connecting links) 4 and 7, which, turning on their axes, clamp the workpiece 6 with rollers (pressure elements 1 and 5, as shown in the drawing). After clamping the workpiece 6, a command is issued to activate the rotation of the drive roller (pressure element) 1. The roller 1, rotating, rotates the bung 6 on a part of the circle corresponding to the angular step of turning the workpiece. After that, a command is issued to shut off the drive of the roller and turn on the stroke of the striker 10. When the striker 10 returns to its initial position, the cycle is repeated.
