Description

The invention relates to cold metal forming.

Known press for cutting parts from strip and tape material, containing a frame, mounted on it the bottom plate and the top plate, ⁵ associated with the drive, mounted on the bottom plate cutting matrix and mounted on the top plate cutting punch. Under the bottom plate there is a mandrel held in motion in the vertical direction from the drive, a slide pusher for moving the stack of parts to the conveyor. In the bottom plate is made a hole for the passage of parts and it is the guide part of the mandrel. The material is fed into the working area of the press with feed rollers P3.

The famous press has large _m

dimensions and complex construction.

The closest to the proposed effect achieved is a press for cutting parts from polo2

sovoy and tape material containing a frame with a fixed plate, on which a cutting matrix is fixed, feed rolls, a drive connected through a conversion mechanism with feed rolls and carrying a plate driven in a vertical direction, on which guide crowns passing through a fixed plate are mounted, bearing fixed plate movable plate with a cutting punch, To remove the cut parts in the fixed plate hole [23.

The known press is not sufficiently easy to maintain and difficult to use auxiliary mechanisms for moving and stacking parts in accordance with their shape, is not reliable in the slave and has not enough high productivity of the cutting process. -lee.

The purpose of the invention is to improve service conditions, increase reliability and performance of the process of cutting parts.

This goal is achieved by the fact that in a press for cutting parts of strip and tape material containing a frame, mounted on it a stationary plate and a drive associated with a plate driven in a vertical direction with guide plates passing through a stationary plate and bearing a movable plate located above it feeding rolls connected through a transforming mechanism with a drive, a cutting matrix and a cutting punch, a cutting punch is fixed on a fixed plate, the cutting matrix is mounted on a movable The plate, in the movable plate, has an opening for the passage of parts and additionally has spring-mounted sliders arranged circumferentially displaceable in the radial direction, interacting with the cut out parts, and the feed rolls are fixed on the movable plate.

Moreover, the press is equipped with a cassette for stacking parts installed with the possibility of removal on the movable plate coaxially with the hole.

In addition, the press is equipped with a mechanism for removing parts from spring-loaded sliders.

Moreover, the removal mechanism is made in the form of a mechanical arm mounted on a movable plate.

In addition, the removal mechanism is made in the form of a disk with gripping bodies.

FIG. 1 shows a press for cutting out parts from strip and tape material, a general view; Fig.2 movable plate with a cassette and feed rollers; in fig. 3 “mechanism for moving parts.

A press for cutting out parts from a strip and tape material contains a bed 1 mounted on it (or made in one piece) 'fixed plate 3, connected with plate 4 moving in vertical direction, bearing column guides 5 passing through fixed plate 2 (table) ,

On the guide columns 5 fasten-. Lena movable plate 6, located above the fixed plate 2 (table).

On the fixed plate 2 (table) fixed fixed plate 7 of the stamp, on which the cutting punch 8 is mounted. On the movable plate 6, a ₅ cutting die 9 is fixed.

For the passage of the cut parts 10 of the material 11 in the movable plate 6 is made a hole 12, and to prevent movement of the parts 10.

About behind the punch 8 (also the removal of parts 10 from the punch 8) in the movable plate 6 mounted around the circumference to move in the radial direction of the slider 13, under 15 spring-loaded springs 14.

On the movable plate 6 mounted two pairs of feed rolls 15 and 16, on the shaft 17 of the driving roll, each of which is fixed gear 18, which are engaged with the toothed rack 19 mounted on the top plate 6.

On one of the shafts 17, an overrunning clutch 20 is placed, on the outer cage of which a gear 21 is mounted (or made integral) meshing with a rack 22 mounted on a fixed plate 2 (table).

At the base 1, the roll holder 23 is installed and the mechanism 24 for moving parts 1 to the next working position can be installed.

In this case, a displacement mechanism is mounted on the upper plate 6, which includes a horizontally located power cylinder 25, on the rod 26 of which the force cylinder 27 is fixed vertically on the rod

28 which mounted gripping body 29.

To create an interoperable backlog of parts 10 on the top plate 6 is mounted coaxially with the hole 12 of the cartridge 30, which is made verti! tip protrusion 31. Gripping organs

29 can be fixed to disk 32.

Press for punching parts of the strip and tape material works as follows.

When moving the movable plate 6 down cutting punch 8 cuts down the part 10 of the material 11. Part 10 through the hole 12 enters the cassette 30. In this part 10 put the sliders 13, compressing the spring 14.

During the course of the movable plate 6 upwards, the sliders 13 remove the part 10 from the pouch of the sleep 8, which enters the cassette ^ 0. Gear rack 22 through gear

21, the overrunning clutch 20, the shaft 17, the gears 18 and the toothed rack 19 drive the feed rollers 15 and 16, which move the belt 11 to the feeding step. Then the cycle repeats. five

When using a press with other processing machines, a moving mechanism is installed on the movable plate 6.

When moving the movable plate 6 ^{, 0} upwards, the power cylinder 25 is turned on, the rod 26 of which moves the power cylinder 27 to the area of the bore 12. The cassette 30 to the moving plate 6 is not installed in this case. 15

The ram 27 is turned on, the rod 28 of which moves the gripping member 29 down to interact with the part 10. The claw 10 is gripped by the gripping body 29 and 20 turns on the ram 27'to reverse movement <and its rod 28 moves the gripper 29 with the detail 10 up . Then include the power cylinder 25, the rod of which moves 25 the power cylinder 27 with the gripping body 29 to the mechanism 24. The gripping body 29 lowers the part 10 into the slots of the mechanism 24.

The press is quite convenient and Reliable in operation, its design allows the use of auxiliary mechanisms of any design, in particular a cassette for stacking parts, mechanical arms for moving workstations from one position to another.
