Description

The invention relates to mechanical equipment for cutting non-metallic materials such as rubber cords and is complementary to the main author. No. 1073091.

The aim of the invention is to improve the quality of the obtained blanks, as well as the productivity of the machine.

Figure 1 shows a machine for measuring cutting material, front view, figure 2 - section aa in figure 1; on fig.Z - view B in figure 1, on figure 4 - section bb In fig.Z; on fig.Z - type G figure 1; figure 6 is a view of D in figure 5; in fig. 7 is a view of E in FIG.

The cutting machine contains a frame 1, a table 2, a cutting mechanism 3, a pneumatic drive 4, electrical equipment 5. The cutting motor 3 of the cutting mechanism 3 is connected via a V-belt drive 7 to a disk knife 8 fixed on the shaft 9 of the rocker arm 10, which is movably fixed on the bracket 11 The knives 8 are brought in and removed from the material being cut 12 by means of a pneumatic cylinder 13, which is hinged in the frame 1. Table 2 serves to receive and measure the desired length of the cut piece. With this (Purpose, on the table 2 a step feed assembly is mounted, consisting of a guide axis 14, on which a bracket 15 with an electromagnet 16 is fixedly mounted. Measuring 17 electromagnet 16 has a fixing element 18. The bracket 15 is rigidly connected to the rod 19 of the pneumatic cylinder 20 supply of the workpiece. On the guide axis 14 there is a stop 21 with a final microswitch 22 fixed on it. The stop 21 can be fixed in a different position depending on the required length of the workpiece being cut. orachivatsya on the axis 23. On the table 2 there are guide rollers 24 and a pressure roller 25. On the rod 26 is mounted a bracket 27, on which the ratchet wheel 28 and the disk 29 are fixed on the axis 30. On the disk 29 there are plates 31 that are connected to the pawl 32, axis 33, Grip 34 for feeding material 12 from accumulator 35 to the cutting zone is screwed onto disk 29. The stop bar 26 is fixed at one end on the axis 37, the other end is connected to the spring 38. The control panel 39 is mounted on the frame

1. The armature 17 of the electromagnet together with the locking element 18 in the de-energized state of the electromagnet is raised using the spring 40.

On the table 2, a cradle 41 is fixed with slots for the entrance of circular knives and an open groove for the material being cut, the surface of which is equidistant to the surface of the cut

material. On the cutting mechanism 3, elastic elements 43 in the form of strips, located between the disk knives, are attached to the fence 42 of the circular knives 8. To control the work of the machine tool on the table 2 and the bracket

11, fixed end switches 44, 45 and 46 are fixed. The inclined tray 47 serves to receive and guide the cut bushings into the container.

Dimensional cutting machine works

in the following way.

The material 12 is passed between the guide rollers 24, the presser

5 by the roller 25 and the locking element 18 of the electromagnet 16. When the start button on the remote control 39 controls is pressed, the locking element cuts into the material 12, the rod of the pneumatic cylinder 20 begins to move the bracket 15, and with it the electromagnet 16 and the material 12 to the cutting zone. Go to stop 21, the bracket 15 presses the final microswitch 22, which gives a signal to supply the rocker arm

5 10 and knives 8 of the cutting mechanism 3 to the material 12 by means of a pneumatic cylinder 13. In this case, elastic strips 43 encompass a part of the material being cut 12 protruding above the top of the comb, and clamp it. As the rocker 10 is lowered, the clamping force increases due to the elasticity of the strips 43. The disk knives 8 touch the material 12 and cut it into sleeves. The locking element 18, cutting into the material 12 perpendicular to its axis, remains there until the knives 8 cut the material into the sleeves. After cutting the workpiece, the yoke 10 presses on the final microswitch 44, which gives a signal to ensure the electromagnet 16 and the return of the bracket t5 to the original one.

5 position. The spring 40 lifts the magnet 17 of the electromagnet upwards and the locking element 18 mounted into it goes out of engagement with

material 12. Go to the initial position, the bracket 1.5 presses the final microswitch 45, which gives a signal to lift the rocker arm 10 with the knives 8. The rocker arm rises 10. At the same time, the circular knives 8 exit the comb with the material being cut 12, and sleeve material remains clamped by elastic elements 43. As the rocker arm 10 with the knives 8 is lifted, the clamping of the finished sleeves loosens and in the upper position when the knives 8 completely come out of the slots of the cradle 41, the elastic elements release the cut bushings . The rocker 10 presses the final microswitch 46, which gives a signal to the electromagnet 16. The locking element 18 penetrates and the material 12 is fed into the cutting zone. Fixed on axis 30

the disk 29, receiving from the rod 26 translational motion, the bar 31 rests against the stop bar 36 and makes a rotational movement in the bracket

from 27 to one Shan. The disk cannot turn to the other side, since the pawl 32, sitting on axis 33, abuts the ratchet wheel 28. The number of slats 31 is multiple to the number

10 cuts the workpiece. The stop bar 36, in the course of the return stroke of the rod 26, is rotated in the axis 27 only in one direction in order to pass the next bar 31, which is facilitated by the spring 38.

J5 The last bar interacts with the gripper 34, which, during the return stroke of the rod 26, enters the slot in the accumulator 35, picks up and output, another workpiece into the cutting zone. The cycle then repeats automatically. Cut off the workpiece fall on the inclined tray.
