The drive of the rotary feeder is made in the Yoke of the Maltese mechanism, while the seal holder is rigidly mounted on the leading link, and the feeder is on the driven link of the Maltese mechanism. The height-adjustable spring preload of the product to the base of the mandrel is placed between the position of the parts to the mandrel and the position of the mark and is made curved with an angle of elevation above the position of the mark, 1 zp f-ly, 5 ill.

Description

The invention relates to the processing of metals by pressure, in particular to winding devices, and can be used for branding products such as bushings.

A device for branding is known comprising a stamp holder attached to the frame, an inclined tray, a piece-by-piece feeding mechanism, a slide mounted on the frame with the possibility of reciprocating movement from the tray to the brand holder, and a mechanism for aligning the ends of the products.

The closest technical solution to the proposed technical solution is a marking device comprising an electric drive mounted on a bed with the possibility of rotation of the drum with mandrels for the base of parts and a brand holder.

The disadvantages of the known solution are as follows:

low productivity, since the design of the device does not ensure the continuity of its work, and when feeding and removing parts, a pause is necessary;

low quality of branding, since during the operation of the device it is possible to move the product upward when it is sliding along the copy;

the complexity of the device is due to the presence of an additional rigid connection for the installation of the adhesive holder, the presence of the adhesive carrier and the pneumatic cylinder of the switchgear.

The aim of the invention is to increase productivity and quality.

To this end, the device is equipped with a puller installed with an angle of elevation above the plane of the trajectory of movement | (L

The mandrel of the feeder mandrels is box-shaped with a groove and shelves along the entire length of the puller in its lower part, and the feeder’s rotation drive is made in the form of a Maltese mechanism, on the leading link of which the adhesive holder is rigidly mounted, and on the driven link, the feeder,

ycfpoliCTBO is also equipped with a height-adjustable spring preload of the product to the base of the mandrel, mounted on a puller located between the position of the feeder Schdeli on the mandrel and the stigma position and made curved with an elevation angle above the stigma position,

In FIG. 1 shows a general view of the device; in FIG. 2 is a view A in FIG. 1; in FIG. 3 is a section BB in FIG. I; in FIG. 4 - puller; in FIG. 5 shows the relative position of the puller and the article above the plane of the path of movement of the ends of the mandrel of the feeder.

The branding device is mounted on the frame and comprises an electric motor 1, which through a V-belt drive 2 and a worm gear 3 is connected to the Maltese mechanism, which consists of a driving link 4 and a driven link 5 made with slots.

A pin 6 is fixed on the leading link 4 for sequential interaction with the slots of the driven link 5. On the leading link 4 of the Maltese mechanism, the adhesive holder 7 with the mark is rigidly mounted, and on the driven link 5 - the product feeder 8 in the working position with mandrels 9 mounted on bearings with possibility of free rotation. The piece feed mechanism of the products is fixed on the frame and comprises a cutter 10 and a tray 11 for orienting the products in a vertical position with respect to the mandrel 9 coaxially located underneath.

A height-adjustable spring igniter 12 of the article is mounted on the frame to the base of the mandrel 9, located between the position of the feed to the mandrel and the position of the mark and made in a curved shape with an elevation angle above the position of the mark. The presser 12 is mounted on a puller 13, installed with an angle of elevation above the plane of the trajectory of movement of the ends of the mandrel 9 of the feeder 8. The puller 13 is box-shaped with a groove and shelves along the entire length in its lower part and is designed to take products from the mandrels 9 and transport them to the container . To adjust the depth of the stigma, adjusting screws 14 are provided on the stigma holder 7 with a stigma.

The device operates as follows.

Pre-oriented in vertical position relative to the axis

in the tray 11, the parts are individually delivered by the separator 10 coordinated by the rotation of the Maltese mechanism onto the mandrel 9 located at the moment the driven link 5 is stopped under the tray guide, the axes of which are

This position is on one straight line. Coordination is carried out using a microswitch mounted on the slave link 5 of the Maltese mechanism, which supplies a signal to the electromagnetic

cutter 10, After the part arrives at the mandrel 9, the driven link 5 is rotated by an angle of rotation, and the part, the passage under the spring preload 12, is fed to the marking position, the driven link is stopped 5. In this position, the adhesive holder is wrapped in one revolution of the driving link 4 7 with a mark on the part that rotates with the mandrel 9 mounted on bearings

on a fixed feeder 8. The depth of the marking is regulated with screws 14. After the marking, the next follow-up link 5 is rotated by the angle of rotation. The next part is supplied to the marking position, and the branded part is moved to the puller 13, the groove edges of which pry the part on the mandrel 9 and, as it moves in the puller 13, it is removed from the mandrel. The lifting angle is selected so that the parts do not slide off the puller 13, but, pushed by mandrels, move along the puller 13 in a container.

Thus, for one revolution of the driven link 4 is the stigmatization of tubular

parts mounted on the mandrel 9, and when the leading link 5 of the Maltese mechanism is rotated by an angle of rotation, the part is supplied to the marking position and the branded parts are removed. With the rhythm

operation depends on the rotation speed of the driving link 4 and the angle of rotation of the driven link 5.
