SU1498592A1 - Cutter for chopping metal chips - Google Patents

Abstract

The invention relates to the processing of metals by pressure and can be used in the metallurgical industry for grinding metal chips. The purpose of the invention is to increase the productivity of scissors. The scissors contain a bed 1 with a fixed knife 2 fixed on it, the blade 5 and the clamping beam 11. The clamping beam 11 is spring-loaded to the bracket of the knife beam 5 from above, and from the bottom by means of rollers 17 mounted on the knife beam. The rollers 17, interacting with the curved groove 19 of the pressure beam 11, move it downward, moving the chips to the cutting zone of the knife beam 5. The pressure beam performs the function of a feed mechanism, which simplifies the design of the scissors. 5 il.

Description

The invention relates to equipment for grinding metal chips and can be used in metallurgical and machine-building plants.

The aim of the invention is to increase the structural design and increase productivity.

Figure 1 shows the scissors, side view; figure 2 is a section aa in figure 1} in fig.Z - node I in figure 2; figure 4 - section bb in figure 1; Fig, 5 is a section bb In figure 4.

Scissors for shredding chips contain a bed 1 on which a fixed knife 2, a table 3, a bunker 4, a knife beam 5 with a knife 6 are fixed, the guides 7 of the knife beam 5 attached to the bed 1. Perpendicular to the front of the scissors is a crank shaft 8, receiving rotation from the electric motor through a wedge-belt transmission by means of a connecting rod 9 mounted on crank (centric) necks and a finger 10 connected to the knife beam 5, A presser beam 11 with teeth 12 is installed on the front of the scissors lower part,. The guide 13 of the pressure beam 11, the spring 14, the bracket 15 of the knife beam 5, form a spring-loaded hinge of the knife beam. In the lower part of the knife beam through finger 16, rollers 17, bracket 18, curvilinear, groove 19 mounted pressure beam 11, which is mounted on the knife beam 5. On the base 1 wedges 20 are located to allow
