Abstract

The invention relates to the processing of meta seam pressure, in particular to machines for grinding metal scrap and waste. The purpose of the invention is to increase the reliability and productivity of scissors for cutting scrap metal and waste. When moving the hydraulic cylinder 8, the yoke 7 simultaneously sticks knives parallel to the direction of movement of the scrap (L) on the scrap. When the perpendicular knives are lowered for the first time, a cross-section is made. The cut piece L is placed on the transfer table 9, which, after raising the perpendicular knives, returns to its original position along with L. During the subsequent push cycle L, coming from the chamber, moves the cut piece L under the knives parallel to its movement and during the next course knives about 5; cut L in a longitudinal direction, I hp f-ly, 2 ill.

Description

The invention relates to the processing of metals by pressure, in particular to machines for grinding metallic iron and waste, and can be used in scrap processing plants, as well as in metal processing plants.

The aim of the invention is to increase the reliability and productivity of shears for cutting metal scrap and scrap.

FIG. depicts scissors for cutting metal scrap and scrap, front view; figure 2 - section aa in figure 1.

Scissors for cutting metal scrap and waste contain a chamber 1, a frame 2, a cutting unit comprising two pairs of interacting knives 3, arranged parallel to the feed direction of scrap and symmetrically relative to the longitudinal axis of the chamber, and one pair of knives 4, arranged perpendicular to this direction. Each pair of knives includes fixed knives 5, located on frame 2, and movable inclined knives 6, located on traverse 7, driven

movement by a hydraulic cylinder 8. Transmitting perpendicular to the feed direction

Table 9 is placed between fixed 5 knives arranged parallel and perpendicular to the feed direction of the scrap, and under the action of an inclined b knife located perpendicular to the movement of the scrap, has the ability to oscillate in a vertical plane around the axis 10 using a spring 11.

The scrap is fed into the chamber 1 by the pusher 12. The clamps 13 are moved using the hydraulic cylinder 14 synchronously with the movement of the knives 4 in the direction perpendicular to the feed direction of the scrap.

Scissors for cutting metal scrap and waste work as follows.

Scrap metal is loaded into chamber 1, an automatic cycle is turned on. The pusher 12 scrap is fed under the clamps 13, which, moving under the action of the hydraulic cylinder 14, are pressed against it and partially pressed.

simultaneously lowers to

scrap knives 3 and 4 arranged parallel and perpendicular to the direction

scrap movement. At the first lowering of the knives 4 (after the start of work), a transverse cut is made, the cut off piece of scrap is placed on the transferring table 9, which after raising the knives 4 returns to its original position along with the crowbar. During the subsequent pushing cycle, the scrap coming from chamber 1 moves the cut piece of scrap under the knives 3, which are parallel to the movement of the pusher 12, and the next time the knives 3 move, the scrap is cut in the longitudinal direction. At each subsequent rounding cycle, a new piece of scrap is moved for slitting, etc.

Claims (2)

Claim 1. Scissors for cutting metal scrap and waste containing a bed, a loading chamber, clamps, a pusher, a cutting unit made in the form of two fixed knives mounted on a bed and two inclined movable knives mounted on a beam, one pair of knives being perpendicular the direction of the scrap supply, and the other parallel to this direction, which differ but also perpendicular to the direction of scrap supply, and under the action of an oblique knife, located perpendicular to the movement of the scrap, has the ability to oscillate Yelnia movement in a vertical plane about the axis 10 by a spring '11. The scrap is fed into the chamber 1 by the pusher 12. The clamps 13 are moved using the hydraulic cylinder 14 synchronously with the movement of the knives 4 in the direction perpendicular to the fact that, in order to increase reliability and productivity, they are equipped with a table located between the fixed pair of knives and located parallel to the direction of scrap supply with an additional pair of knives, the movable knife of which is made inclined, with 40 this table is made with the possibility of moving with inclined knives in a vertical plane, the inclined knife of the additional pair is rigidly connected to the traverse, a pair of knives located in the direction of scrap supply. Scissors for cutting metal scrap and waste are as follows. Scrap metal is loaded into chamber 1, and an automatic cycle is activated. The pusher 12 scrap is fed under the clamps 13, which, moving under the action of the hydraulic cylinder 14, press it and partially pressed. When moving the hydraulic cylinder 8, the crosshead 7 simultaneously lowers the knives 3 and 4 on the scrap, located parallel and perpendicular to the direction perpendicular to the direction of scrap supply, separated from the pairs of knives located parallel to the direction of scrap supply at a distance equal to the pusher pitch, and the length of the knives located perpendicular the direction of scrap supply is equal to the width of the loading chamber. 2. Scissors according to claim 1, characterized in that pairs of knives arranged parallel to the direction of scrap supply are evenly spaced across the width of the chamber.
