Abstract

The invention relates to the processing of metals by pressure and can be used to feed material into the treatment area. The goal is to expand the technological capabilities by reducing the time of the working stroke of the feeding carriage and increasing the time of its idle speed. The material is fed into the treatment area by a feeding carriage moving along rails mounted on the base. The carriage is driven from the drive shaft through the transmission and conversion mechanisms. The transmission mechanism includes a drive sprocket mounted on the drive shaft and a driven sprocket having a radial stroke. Driving sprocket mounted on the driven shaft using a radial groove. The sprockets encloses a closed chain, provided with a tension node of a falling branch. The tensioning unit is made in the form of a lever that is spring-loaded in the direction of the falling branch of a chain pivotally mounted at one end on the base and bearing on the other end of the roller. The roller is interoperable with the chain. The transforming mechanism is designed in the form of an axis fixed perpendicular to the guides on the base. The carrier is loosely mounted on the axle and connected to the driven shaft, and the gear wheel is fixed. 2 A pivot gear is hinged on the drive, engaging with a gear wheel.

Description

The invention relates to the processing of metals by pressure and can be used to feed material into the treatment area.

The purpose of the invention is the expansion of technological capabilities by reducing the working time of the falling carriage and increasing its idling time.

FIG. 1 shows a diagram of a device for feeding material into a treatment zone; in fig. 2 is a view A of FIG. one; in fig. 3 - kinematic diagram of the device.

The device includes a base 1, guides 2, mounted horizontally on the base 1, axis 3, mounted vertically on base 1, carrier A, freely mounted on axis 3, a stationary gear wheel 5 mounted on axis 3, a bevel gear 6 mounted on a carrier 4, the driven shaft 7, mounted on the base t perpendicular to axis 3 and carrying a bevel gear 8j which engages with a bevel gear 6, driving an asterisk 9, feeding the carriage 10 with a straight groove 11, perpendicular to the direction 2 and axis 3 , drive shaft 12, carrying drive sprocket 13, closed circuit 14, spanning asterisks 9 and 13, tensioning unit 14.

The tensioning unit of the chain 14 contains a lever 15 pivotally fixed by means of an axis 16 on the base 1, a tension roller 17 mounted by means of an axis 18 on the lever 15 with the possibility of interaction with one of the branches of the chain 14, an extension spring 19, one end of which is connected to the lever 15 and the other is fixed on the base 1.

The asterisk 9 has a radial groove 20 for accommodating the shaft 7. An asterisk 9 is mounted on the shaft 7 with the possibility of an adjustment movement for changing the eccentricity. The eccentricity is adjusted by moving the shaft 7 through the groove 20.

On the carrier 4 with the help of axis 21 a movable gear (satellite) 22 is mounted, the entrances to gear with the gear wheel 5, an eccentric eccentric pin 23 is fixed on the movable gear (satellite) 22, on which the floor is hinged

Zushka 24 moving along the groove 11 of the feeding carriage 10.

The device works the following way um.

The drive shaft 12, through the sprocket 13 and the chain 14, drives the sprocket 9, which, through the shaft 7, bevel gears 8 and 6 rotates the carrier 4 around the axis 3. The gear 22 rolls around the fixed gear 5 and rotates on the axis 21. At the same time, the finger 23, rotating together with the gear 22, moves the slider 24 along the groove 11. The slider 24 reciprocates the feeding carriage 10 along the guides 2.

The asterisk 9, due to eccentric stretching relative to the shaft 7, converts the uniform rotational movement of the asterisk 13 (drive shaft 12) into a slow-accelerated rotational movement of the carrier 4.

The accelerated rotation of the carrier 4 is carried out during the working stroke of the press (not shown), and slowed down - during the idle stroke of the press. The tension unit carries out a constant tension of the chain 14.
