Abstract

The invention relates to metallurgy, in particular, to machines for separating profits from castings. The purpose of the invention is the expansion of technological capabilities. The chipping device comprises a frame 1, a chipping mechanism with a power cylinder 7, levers 4 and a striker 5 mounted on them with an oval working face. The bed is made in the form of a frame base with racks 2 fixed on it, in which by means of two parallel axes 3 and 6 the levers 4 and the power cylinder 7 of the chipping mechanism are pivotally mounted. The mechanism of the casting clamp is made in the form of a support fixed on the frame and an eccentric clamp. 1 hp f-ly, 6 ill.

Description

The invention relates to / processing. metals by pressure and can be used in mechanical engineering for separation of profits from castings.

The purpose of the invention is the expansion of technological capabilities,

FIG. 1 shows a chipping device, general view; FIG. 2 is a section A-A in FIG. 1; in fig. 3 is a section bb of fig 1; FIG. 4 is a section through JB-B in FIG. 2, - FIG. 5 is a view of D in FIG. 1; fig 6 is a section dd in fig about 5, °

The chipping device contains a frame base 1 with poles 2, on the upper ends of which on the axis x 3 there are mounted levers 4 with a striker 5 on their own (one end o On the racks 2 below their top on the axis x 6 is hinged

pneumatic cylinder 7, of which the arm 8 is pivotally attached to the levers 4. In the frame base 1, on one side, an eccentric clamp 9 is installed, and the other side has a support 10, in the body of which two eccentric 11 are mounted, rigidly mounted through the upper and lower sheets of the frame base. The eccentric axes 12 are provided with handles 13. Load-gripping lugs 14 located on an axis passing through the center of gravity of the device are welded to the uprights 2, In the frame. Based on 1 in the center there is an opening for the passage of a profit of 15 ingot.

Expansion of technological capabilities is due to the performance of the striker with a rounded face and fixing it on the levers garnini installed-.

on racks that are associated with the latest pneumatic cylinder; This gives; the ability to hit on arrived m, located horizontally, vertically and at an angle to the vertical

Before using the chipping device at all profits 15, to be separated from the castings, a shallow (up to 10 mm thick) incision is made at the bottom of profit 15, fitting into the central angle

For operation, the chipping device is suspended by slings over the load-bearing shackles 14, is installed with a crane over the center of the notch arc. In this position, the device with the eccentric clamp 9 and the support 10 mounted on the casting, encompassing the frame 1 of profit. profits 15, slightly turning the levers 4 away from the pillars 2,. Then fix the device to at 15, for which the eccentric 9 rotates to select the gap between it and the profit surface 15 Then uniformly rotate eccentric handle 11 for m- ki 13 and support 10 firmly to the surface prizhima- dissolved pribshi 15o levers 4 and 5 with the striker zani- air cylinder 7, at maet. This is the initial position shown in FIG. 1; Next, air is supplied to the pneumatic cylinder 7 by its rod 8.

Levers 4 are moved and rotated clockwise on axles 3, set in the upper position. In this case, the pneumatic cylinder 7 rotates on axle 6 to the position shown in FIG. pulls in, turning the levers 4, and accelerating the free fall of the striker 5, which hits the bottom 15, breaking it off from the casting
