Description

The invention relates to a machine tool industry and can be used in machine tools for cutting rolled sections.

The purpose of the invention is to increase productivity by ensuring free supply of the bar with burrs arising during machining.

FIG. 1 shows a machine in section, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows the node I in FIG. one; in fig. 4 shows a section BB in FIG. 3

The machine contains the lower 1 and upper 2 bed. A drive (not shown), a cooling system 3, and an electrical panel with a remote control (not shown) are located inside the frame 1. On the frame .1 fixed mechanism 4 feed rod. On the stanna 2, there is a cam shaft 5 with cams 6-9, milling heads 10 and 11, clamp 12 and swinging stop 13. Clamp 12 consists of an upper movable cracker 14 and a lower fixed leg biscuit 15. On cracker 14 there is a strap 16 with a hole .

The device works as follows.

In the off position of the machine clamp 12 is open. The stop 13 is retracted by longitudinal movement on the axis 17 and the bar 18 is manually inserted into the guide tube 19 through the open clamp 12. The bar passes through the hole 20 of the bar 16. The bar

18 is moved along the pipe 19 until it stops against the feed mechanism 4 and continues. move the bar 18 together with the feed mechanism 4 until it becomes possible to set the stop 13 to its original position, at which the bar 18 is fixed between the feed mechanism 4 and the stop 13.

Pressing the Start button on the remote includes the machine. In this case, the cam shaft 5 begins to rotate. The cam 7, by moving the stop 13, sets the bar 18 in contact with it in the clamp 12 to the working position. After that, the cam 6 closes the clamp 12 through the lever 21, the stop 13 moves away from the bar to its original position and the mills 10 and 11, driven by the cams 8 and 9, begin to process the bar 18. With the clamp 12 closed, the bar lies on the cracker 15, not touching the surface holes 20.

At the end of the machining of the bar 18, in the u: the process of which the piece is cut off from the bar 18, the cutters 10 and 11 move to their initial position, the clamp 12 is opened by moving the upper cracker 14 upwards. Together with the cracker 14, the bar 16 moves up, lifting the bar 18 behind itself. The feed mechanism 4 moves the bar together with the cut piece in the direction of the stop 13. In this case, the part coming out of the clamp falls freely into the receiver and the bar abuts against the stop 13. After this cycle repeats.
