Abstract

The invention relates to the field of mechanization of cold working of metals, in particular to complexes for automatic punching, details of tape material. The purpose of the invention is to increase the productivity of the complex by automatically detecting the non-measuring residue (BUT) of the tape material (LM), as well as removing both finished parts and non-measuring residues by means of a robot. The complex contains a press, a control unit, cassettes with an LM, a mechanism for moving the cassettes and a device for the stepwise delivery of NM in the press. The latter contains a frame with a driven carriage, fixed stops and a movable stop. The complex is equipped with a photosensor and a photodetector for determining BUT tapes mounted on a movable stop, as well as a robot for removing finished parts and BUT tapes installed in technological sequence with a press. The photo sensor, the press and the robot are interconnected by means of a control unit. With the passage of the end of the unmeasured remainder of the LM beam of light from the photo sensor enters the photodetector. This is a signal to the control unit to transition to a specific work program. 4 il. a (g e with to with 00 bo

The aim of the invention is to increase productivity.

Figure 1 shows the complex, general view; 2 is a node (in FIG. 1 IQ (device for step feed, plan); FIG. 3 is a kinematic diagram of the device for step feed, in FIG. 4 a section A-A in FIG. 2.

The complex for stamping parts of 15 tape material includes a press 1, a control unit 2, cassettes 3 for mounting tape material in them, cassette transfer mechanisms consisting of stacker cranes 4, conveyors 5 with a drive 6. In addition, com-pex has a device 7 for the step-by-step supply of the tape material to the press 1 and installed in the technological

sequences with press 1 robot 25 is positioned so that the ends

8, which removes finished parts into a container 9, and non-dimensional blanks into a container 10.

The device for the step-by-step supply of tape material to the press 1 is made of S in the form of a frame t1, on which a cylinder 12g is mounted, the rod of which is connected to a carriage 13 mounted on two guides 14.

The carriage 13 has a gripping body 15 for feeding the tape material into the press 1. In addition, a double-sided hydraulic damper 16 is fixed to the carriage 13 with output ends 17 and 18 of the hydraulic damper rod 16,

Along the axis of movement of the ends 17 and 18 of the rod, stops 19 and 20 are fixed to the frame 1I.

On this frame 11, a SUBS1-1ZHNYY stop 21 (fig. 3) is mounted, which consists of a housing 22 and an air cylinder 23 fixed to it with a stem 24, designed to interact with the output end 17 of the hydraulic damper 16. The housing 22 is mounted on the guide 25 of the frame 11 seconds the possibility of movement by means of a screw gear, made of a nut 26 rigidly fixed in the housing 22 and of a screw shaft 27 driven by the drive 28.

A bracket 29 with a photosensor 30 and a photodetector 31 mounted on it is rigidly fixed on the housing 22,

the beam of the photo sensor 30 is directed beyond the boundary position of the feed pitch against the movement of the tape by the value L; necessary for the gripping body 15 of the carriage 13 and the tongs 32 to disperse thereon when the tape is fed into the press, as well as the minimum length of the tape entering the press 1 for capture her robot.

On the frame 11 is fixedly mounted gripping body, made in the form of mites 32, with a drive 33.

The complex works as follows.

The cassette 3 with the belt material is delivered by the stacker 4 from the supply depot (not shown) and installed on the conveyor 5. The drive 6 is turned on, the conveyor 5 and the cassette 3 is moved until the tape material is in the plane of supply to the press . . .

it is protruded from the cassette 3 by the amount necessary for gripping by the gripping body 15 and gripping 32 (FIG. 1). The carriage 13 at the same time is located in an outgoing Q polssion, i.e. the end 18 of the rod, the hydraulic damper is in contact with the stop 20, and the gripping body 15 is disclosed (FIG. 3, dotted line).

The cylinder 12 is turned on, while the carriage 13 is moved towards the cassette 3 until the end 17 of the hydraulic damper 16 is engaged with the stop 19. The tape is gripped by the body 15. hydraulic damper 16 with a stop of 20 o

At the command of the control unit 2, the robot 8 removes the unmeasured end of the tape material from the press 1 and stores it in the container 10 (Fig. 1).

At the same time, the actuator 28 is turned on, which, by a command from the control unit 2, moves the sub-support 21 by means of a screw gear to the step of supplying the tape material to the press 1O Then the pneumatic cylinder 23 is turned on to expel the stem 24,

The gripping body 15 releases the tape material and, together with the carriage 13, driven by the cylinder 12, moves until the rod 24 interacts with the end 17 of the damper rod 16.

The gripping body 15 clamps the tape material, and the gripping body 32 expands it and the cylinder 12, moving the carriage 13 with the gripping body 15, moves the tape material by the feed increment until the end 18 of the hydraulic damper 16 is engaged with a fixed stop 20.

The press 1 is turned on. A working stroke of the press 1 takes place, and at the command of the control unit 2, the robot 8 removes the finished parts from the press 1 and stores them in the container 9. At the same time, the light beam from the photo sensor 30 reflects from the tape material and does not enters the photodetector 31.

The cycle is repeated until all the dimensional tape material is fed into the press 1.

When the end of the unmeasured remainder of the tape material passes, the light beam from the photosensor 30 enters the photodetector 31. This is the signal for the control unit 2 to switch to a new work program.
