SU22257A1 - Two spindle button making machine - Google Patents

Description

The proposed machine, intended for the manufacture of buttons from bone, etc. of the material by simultaneously turning them on both sides, is equipped, besides the two spindles required for this, also with a device for fixing and feeding the plate being machined.

In FIG. 1 shows the front view of the machine; FIG. 2-horizontal section along the line OLfig. one; FIG. 3- view of the feeder from above.

From the drive shaft 5 of the machine by means of a worm gear, the 8th receives a rotation transverse to the axis D on which two eccentrics K, K, alternate, sit. schenny relative to each other at 180 °. Through the connecting rods M, M n of the articulated levers H, H, the eccentrics report the reciprocating movement of the spindles m D, D, carrying the cutters which sharpen the buttons. An eccentric T is mounted on the axis L, intended to rotate through the arms J and F with the ratchet dog C and associated gears, gears, C rollers H. each button is moved from it by these rollers in a direction perpendicular to the spindle. The spindles receive rotation from the shaft by means of belts, thrown over the pulleys B, B vi G, G.

The subject matter of the invention.

1. A two-spindle machine for making buttons, characterized in that the levers //, H, driven by connecting rods M, M from eccentrics K, / C mounted on axis L, are designed for longitudinal feeding of spindles D, L. rotation of the pinion gear fixed to it from the worm 5, sitting on the drive shaft B.

2. An application in the machine described in p. 1 of the device for fixing the treated bone plate- "stina", characterized by the use of rollers H and H, from which the rollers H are rotated through the gears D and ratchet X arm F Y associated with eccentric T, sitting on the axis of L.
