SU530762A1 - Drop to guillotine shears for stopping metal on the conveyor - Google Patents

Description

one

The invention relates to the field of master building and can be used for dimensional cutting of sheets on guillotine shears.

Known lowering stop containing carriages, having the possibility of reciprocating movement along the guides along the metal feed axis, on each of which a limiter is mounted with the possibility of raising and lowering by means of an individual pneumatic actuator, as well as a fixing mechanism for each carriage.

However, when operating such an abutment, it is not possible to ensure parallelism of the edges when cutting bright sheets.

In order to eliminate this drawback, each carriage of the proposed stop is provided with an additional stopper, the main and additional stoppers are installed on the sides of the carriage, and the carriage locking mechanism is implemented in the form of crackers installed in the holes in the carriage underneath the guides and having the possibility of moving perpendicular to the axis feeding metal in opposite directions from an individual drive.

FIG. 1 shows the lowering of the stop to the guillotine shears to stop the metal on

transporter, plan view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a section along BB in FIG. one; in fig. 4 is a view along arrow B in FIG. 3; in fig. 5 is a section along G ‑ Y in FIG. four.

Perpendicular to the movement of the conveyor 1, there are several, corresponding to the number of specified stops of the carriages 2, moving in directions 3, along the metal feed axis from one drive 4. On each carriage, limiters 5 are mounted on each side and clamp mechanisms 6 are used for clamping the carriage. lifting and lowering is provided with an individual pneumatic actuator 7, which is automatically controlled through an electric air distribution valve 8 with end switch 9 (not shown in the drawings) mounted under the pedal th control guillotine shears (not shown).

Claims (1)

In each carriage there are holes along the sides with sleeves 10 for descending lowering rods 11, openings with sleeves 12 dp of guides 3, groove 13 through the center of the hole for passage of the driving screw 14 interacting with nut 15 in the groove and placed under the directional tides 16. in the openings of which mobile crackers 18 of the fixation mechanism are built-in to the small wheels 17. Products have windows 19. through which the breadcrumbs act on the guides. The nut 15 is made detachable and provided with transverse threaded holes into which rods 21 are threaded through the flywheels 20, passing through the thread through the rusks 18 and the coupling 22 on the thread. On the frame of the chain conveyor 1, a measuring line 23 is fixed, 1 mm in division which slides fixed on the carriage 2 and together with it movable pointers 24. For cutting sheets it is necessary to adjust the stop to the specified dimensions. The adjustment for one size is done in the following order. By turning the handwheels 20 through the rods 21, the drive screw is clamped by means of a nut and, at the same time, the guides are released from the clamping with the breadcrumbs 18. After switching on the drive 4, the screw comes into rotation and through the nut moves the carriage in a given direction. Observing the pointer 24, the required size for cutting the sheet is detected along the ruler 23, the drive is turned off. After that, the stop stops for work. The locking is done by a flywheel that rotates in the opposite direction. In this case, the nut 15 is diluted, releasing the drive screw 14, and the crackers, shifting, clamp the guides. Adjustment of the second pair of stops to the second size is done in the same way. This is due to the fact that the nut of the first pair of stoppers is in the expanded state, and the BINT, rotating, moves the carriage of the second pair of stopper, without affecting the first carriage, which is locked with crackers. The operation of the stop after their adjustment is performed as follows. A sheet of unlimited length to be cut is fed through a chain conveyor until it comes into contact with lowering stopper 5 and before that 4 engages the contact of limit switch 9 installed in front of these stoppers. The final stopping of the sheet occurs after its front contact with both limiters, which ensures parallel cutting. Contact with both limiters is made by pushing the lagging side of the sheet to a constantly moving branch (chain) of the conveyor. In the further stopped by the stops, the sheet remains stationary, and the conveyor chains slip under it. Then the cutter presses the guillotine pedal, which includes the guillotine knife and. at the same time it acts on a limit switch set under the pedal. Sheet cutting and one time switch are made through an electric air distributor interlocked with it, giving a command to the pneumatic actuator, which lowers the limiters. The cut-off workpiece released from the stops moves along the conveyor and opens the limit switch 9, which automatically turns on the pneumatic actuator 7, instantly returning the stops to its original position, crossing the path to the next workpiece. Claims of the invention. Lowering stop for guillotine shears for. metal stops on the conveyor, containing I carriages, having the possibility of reciprocating movement along directions along the metal feed axis, each of which has a limiter mounted with the possibility of raising and lowering by means of an individual pneumatic actuator, as well as fixing mechanisms of each carriage, TL, and By the fact that, in order to ensure parallelism of the edges of the sheet during cutting, each carriage is provided with an additional stopper, while the basic and additional stoppers are placed on the sides of the carriage, carriage locking mechanism is in the form of crumbs, installed in a carriage vsholnennyh holes for guide and having a movable perpendicularly metal feed axis in mutually opposite directions or indashidualnogo actuator.
