Abstract

Usage1 processing of continuous material pressure Summary of the invention: the rotor line comprises chain conveyors sequentially mounted on a common frame, blocks with stamping tools, mechanisms for bringing together and disconnecting the parts of the blocks, mechanisms for activating the folding tools Tool blocks are mounted on conveyor chains. The axes of the blocks are parallel to the axes of the sprockets. The mechanism for approaching and disconnecting the parts of the blocks contains copiers fixed on the upper plate of the bed. The actuating mechanisms of the stamping tools comprise additional copiers which are rigidly connected to the respective copiers mounted on the top plate. Additional copiers are shifted odd relative to another by a quarter of a step between stamping tools. When moving conveyor chains, the tool blocks come closer under the influence of the copiers. The material is pressed against the Matrix and, together with the chain and blocks, enters on the one hand the zone of operation of some additional copiers. Punching tools cut down parts. With further movement of chains and tools, tools cut down parts under the influence of other additional copiers. 5 silt with

action of stamping tools; rotary feeding and loading mechanisms.

When the electric motor starts up, the conveyors receive continuous rotation, the stamping blocks are centered on the proximity section, and stamping is performed when interacting with the copiers.

In order to ensure material savings due to the minimum size of jumpers between stamped products, the device may contain additional horizontally closed conveyors oppositely located relative to the processed material, kinematically connected to the main ones through chain conveyors.

The design of the known device is complicated due to the presence of twelve power mechanisms, a rotary feeder and a loading rotor, additional conveyors and chain gears for their communication with the main conveyors, therefore, the reliability of the device is low.

The aim of the invention is to increase reliability and productivity by parallel stamping of Parts from two continuous workpieces and sections at two ends of one workpiece.

This goal is achieved in that in the rotor line for stamping Parts made of continuous material, containing at least two sequentially located on a common frame and connected by a common drive closed chain conveyors with parallel chains covering sprockets, and tension mechanisms, blocks with stamping tools mounted on chains of conveyors, a mechanism for bringing together and disconnecting pairwise interacting parts of blocks in the form of copiers mounted on a bed, a drive mechanism for ampowo tools, according to the invention, the axis of the blocks are parallel to the axis of the sprockets, the mechanism for actuating the stamping tools is made in the form of at least two pairs of additional copiers, rigidly connected with profile copiers, while additional copiers placed on one conveyor are located on different sides of the axis passing through the axis of the sprockets, and at a distance from one another equal to 0.25t, where t is the step of placing the tools, the distance between the axles of the sprockets of one conveyor is 3.5t, p ssto between the axes of two adjacent Stars sequentially set equal conveyors 2,5t, frame formed with the top plate and the line

equipped with housings for placing copiers, guide columns connecting the housings with the top plate, cup springs placed

on columns, adjusting nuts and rollers placed on blocks with the ability to interact with copiers.

Rotor line for stamping parts

5 of continuous material contains a common bed 1 and an upper plate 2, tightened with stitches 3. The bed 1 is equipped with fixed guides 4, with which blocks 5, non-carrying stamping tools, the actuation mechanism of which is made in the form of at least at least two pairs of additional power copiers 6–9, rigidly fixed in the upper plate 2 of the bed 1. The feed belts 11 are fed to the line 11 along the drive rails 10.

Four twin sprockets 12 are connected through couplings (not shown) with a common line drive located at the bottom of the bed

1 and consisting of an electric motor 13, a belt drive 14, and three worm gears

gears 15, while the axis of the stamping

blocks 5 are parallel to the axis m

5 asterisks 12, and blocks 5 are installed with a step for placing stamping tools equal to:, on chains 16, two sequentially located on a common frame and connected by a common drive closed chain

0 conveyors 17 and 18 with parallel chains 16 covering sprockets 12 and tensioning mechanisms (not shown),

Additional copiers 6-9 placed on each of the conveyors 17, 18,

5 are located on different sides of the axis passing through the axis of the sprockets 12, and at a distance from one another equal to 0.25t, where t is the placement step of the stamping tools of blocks 5, each of which contains movable rollers 19, holder 20, guide 21, clamp 22, punch 23 and molding 24 punches, punch matrix 25, ejector 26, molding matrix 27, thrust rollers 28.

5 Additional copiers 6-9 with the help of housings 29 are mounted on the plate 2 by means of guide columns 30 placed in bushings (not shown) installed in the openings of the housings 29. The mechanism of rendezvous and separation in pairs

the interacting parts of the blocks 5 is made in the form of profile copiers 31, rigidly fixed to the frame 1 and having the ability to interact with the movable rollers 19 of the blocks 5.,

Adjusting nuts 32 and plate springs 33 are installed on the guide columns 30, with the help of which additional copiers 6-9 are pressed against the plate 2.

The distance between the axles of the sprockets 12 of the conveyor 17 or 18 is equal to 3.5t, the distance between the axes of the adjacent sprockets 12 of two consecutively installed conveyors 17 and 18 is equal to 2.5t, where t is the separation step of blocks 5 for the purpose of conveyors 17 and 18.

The stamped part 34 is removed along the slit 35 in the container.

The rotor line works as follows.

When the motor 13 rotates, the chains 16 of the conveyors 17 and 18 synchronously move with the tool blocks 5. Rolling along the profile copier 31, the rollers 19 through the bar 21 open the interstamp space of the tool blocks 5. Continuous material in the form, for example, of the belts 11 along the drive tracks The interstep space of block 5, which is in this state at the beginning of the straight path of movement of the chains 16 of the conveyors 17, 18, falls into the open at a break.

With further movement of the tool blocks 5, the link 21 is lowered by a certain amount, while the clamp 22 presses the tape 11 to the upper part of the die cutting matrix 25, the tool block 5 and the tape 11 move together to the working position, for example, to an additional copy 6 or 8, where the die cut the punch 23 is lowered down, making a working stroke, during which the blank is cut from the tape 11, and the molding part 24 is molded part 34.

Then the punches 23 and 24 are lifted in accordance with the movement of the rollers 19 along the copier 31, the clamp 22 continues to hold the tape 11. When approaching the end of the rectilinear portion of the chains 16 conveyors 17 and 18, the stamping space of the tool block 5 is completely open and the ejector 26 pushes the stamped item 34 to skliz 35, by which it falls into the container. 5This line provides enhancement

productivity due to the possibility of parallel stamping of parts from two continuous billets and sections at two ends of one billet, and

0 also contributes to increased reliability.
