Description

one

The invention concerns the mechanization of the deformation process on forging rollers.

A device for feeding workpieces to forging rollers is known, comprising a housing with a feed mechanism mounted thereon, a reversing drive thereof and an automatic control system. However, it cannot provide the possibility of two-sided rolling of the workpiece.

The proposed device is characterized in that the feeding device is made in the form of two rows of drive rollers arranged one above the other, one of which is mounted on a movable frame mounted in the housing and connected through double-arm levers hinged to the housing. pneumatic cylinder.

FIG. 1 shows the proposed device, a general view; pas figs. 2 - top view.

The device consists of a body 1, on which a lower row of rollers 2 is placed, on which the workpiece 3 is placed. The body is fixed to the ends with brackets 4 mounted on rollers 5 and 6. In the body there is a cutter 7 with pneumatic cyclide 8 to stop the product in the middle position. The cutter is enclosed in the holder 9, in which it moves. A cutter with a flag 10 is located in the cutter, which serves to issue the appropriate command through the limit switch I. The fixed sleeves 12 and 13 are rigidly fixed to the body on either side. The pneumatic cylinder 14 is mounted on the holder 12.

for raising and lowering the upper frame with the help of levers 15 and ti 16, pivotally connected to each other. Motor-gearbox 17 is mounted on casing 13. Between casing on podruly {nnannyh tahs 18, frame 19 with rollers 20 is highlighted. Guiding pins 21 are provided for guiding when raising and lowering the frame. p yes rigidly mounted on shafts

23 and 24, respectively, on which the sprockets 25 are also rigidly mounted, which are connected in pairs by chains 26. The shafts are mounted in the housing and frame rotatably. To limit travel

on the rollers, spring-loaded stops 27 and 28 are installed in the shtamp zone, with end switches 29 giving the command to stop the rollers and turn on the rollers 30 of the forging rollers.

The preform is fed by the feed mechanism onto the body rollers while the frame is raised. A command is given to the pneumatic cylinder to lower the upper frame. The blank is pressed

upper rollers to lower rollers

The drive of the device is turned on. The rollers serve the workpiece in the rollers of the right rollers until it stops. The stop, moving, gives a command, through a copepick, to stop the installation drive and turn on the rolls of the rollers. The rolls, making one turn, give the command to reverse the drive of the device. The workpiece is moved by the rollers to the second rolls of the rollers up to the stop, the limit switch stops the drive of the installation and turns on the rolls of the rollers. The rolls, having made one revolution, turn on the pneumatic cylinder and the slam-shut is set to the upper position. The strip goes all the way to the shut-off device, a checkbox closes the limit switch, a command is given to stop the drive of the device. The top frame with the rollers rises up, a command is given to take the product out of the area of the rollers by the unloading mechanism. The product is removed, the unloading mechanism gives

a load mechanism command, and the cycle is repeated.

Subject invention

A device for feeding workpieces to forged rollers, comprising a housing with a feed mechanism mounted thereon, a reversing drive thereof and an automatic control system, characterized in that, in order to provide the possibility of two-way rolling, the feed device is designed as one above the other two rows of actuators rollers, odip

of which are mounted on a movable frame mounted in the housing, connected through two shoulders by means of hinges attached to the housing, with a stem mounted also on the pneumatic cylinder housing.
