Description

Replaced on it by punching tools 13 and stripping 21-22 receives a reciprocating motion. At the same time, the rotational motion is obtained by the drive shaft of the intermittent movement mechanism, the turning part 22 of the stripping tool and the tacho generator. From the shaft, the movement is transmitted to the drum (B) 17. When loading the workpiece (3) 16 into cell B, the last

The invention relates to the field of forge-and-press engineering, namely, the designs of mechanical automatic presses for punching holes.

The aim of the invention is to increase productivity and reliability, as well as improving the quality of manufactured parts.

FIG. 1 is a diagram of the press machine; in fig. 2 - press machine, side view; in fig. 3 - the same, top view; in fig. 4 shows section A-A in FIG. 2; in fig. 5 is a section BB in FIG. 3; in fig. 6 shows section B-B in FIG. 2

The press machine contains a frame 1 with a table 2 installed on it and a crank mechanism 3, one end of a crankshaft 4 which is kinematically connected through gears 5 and 6 of the clutch-brake 7, shaft 8, V-belt drive 9 with the main drive 10 , the other end of the crankshaft of which is connected with the distribution shaft 11 placed on the base 1 with the possibility of reciprocating movement and interaction with the crank-connecting rod mechanism 3, the slider 12 with the tool

stopped. On a subsequent turn, B 3 is fed to the punching position where the hole is punched, while the original 3 is loaded into the next cell B. The refusal to punch falls into the waste container. On a subsequent turn, the B 3 hits the stripping position where the burr is removed with the stripping tool 21-22. 1 Cpf-ly 6 Il.

26 and a safety clutch 27 fixed on the drive shaft 20 of the intermittent movement mechanism. The kinematic connection of the camshaft 11 with the intermittent movement mechanism, the rotary part 22 of the stripping tool and the tachogenerator is carried out by means of a system of 28 gears.

 Press machine works as follows.

From the main drive 10 through the V-belt transmission 9, the included clutch 7, gear wheels 5 and 6, shaft 4

35 slider 12 with punching and stripping tools 13 secured on it .21 gets reciprocating. At the same time, the rotational motion receives the distributor shaft 11, and from the shaft 11 and the system 28

the gears are rotated by the drive shaft 20 of the intermittent movement mechanism, the turning part 22 of the stripping tool and the tachogenerator 26.

When the drive shaft 20 is fully rotated, the driven shaft 19 is rotated 1/8 of its full rotation.

From the output shaft 19, a 1: 1 gear ratio is transmitted to the drum 17. When the cell 18 of the drum 17 reaches the level of the tray 23 of the loading device, the original blank 16 is loaded into the cell. At this point, the drum 17 is stopped.

Upon subsequent rotation of the drive shaft 20, the drum 17 feeds the initial billet to the piercing position, where the hole is punched. At the same time, the original blank 16 is loaded into the next cell of the drum 17. The waste from punching the hole through the device 14 enters the container for collecting waste (not shown). After the next rotation of the drum 17, the preform with the hole is loaded into the cleaning position, where with the help of part 22 the burr is removed from the edges of the punched hole.

At the same time, the following cells

 the drum 17 approaches the piercing position with the initial workpiece and to the loading device.

By the next rotation of the drum 17, the blank with the deburred burr is delivered to the inclined tray 23 of the unloading device and is passed along it to the container of the processed blank or to the next machine, for example, for painting, stamps, etc. During operation, jamming or breakage of the driven and driving shafts 19 and 20 or the drum 17 may occur. In this case, the limit switch (not shown) of the safety clutch 27 causes a signal to the control system that turns off the clutch 7 and the press-breaker stops. During operation, a situation may arise when the cells 18 of the reel 17 do not exactly fit the treatment positions. In this case, the moving tool may damage the drum 17 and other parts. To protect against damage, an electric locking device (not shown) is installed on the drum 17 and the base 1, which controls the position of the cells relative to the axes of the tools.

The command device 25 controls and blocks the operation of the automatic press in automatic and semi-automatic modes. Tacho generator 26 is used to set the stroke frequency of the press machine.

In comparison with the known, the proposed automatic press provides an increase in productivity, reliability and improvement in the quality of machining of parts.
