SU94436A1 - Numerator for automatic stamping under the press of metal products - Google Patents

Description

The subject of the invention is a numerator for an automatic brand — under the press of metal products, which is made in the form of a rotor composed of a system of digital disks connected by concentrically placed sleeves with separating disks and a ratchet mechanism.

The proposed numerator, in comparison with similar devices, is simpler in its design and reliable in operation.

A distinctive feature of the proposed numerator is that it uses a system of spring-loaded pins that interact with the profile cams, and the ratchet mechanism of the numerator is connected with the press slider using a pivotally-fortified leash with a spring-loaded latch on the end.

FIG. 1 shows a longitudinal section of the numerator; on fng. 2 is a plan view; FIG. 3 is a view of arrow A and FIG. one; in fig. 4 is an abed view of FIG. one; FIG. 5 is a view along arrow B in FIG. 2

In the case / numerator is a rotor composed of a system of digital and separating discs.

Six digital disks 2, 3, 4, 5, b and 7 are in eight figures 8, from one to zero, planted around the disk circumference and at a distance of 36 from one another by press fit into swallow nests 9.

Six separating discs 10, 11, 12, 13, 14 and / 5 each have ten keyways 16 slots, which are also separated from one another by a circle of 36.

Digital and divider disks are connected between co6oii with the help of concentric sleeves (shanks of digital disks), a pin 17 and a screw 18.

Extreme digital discs 2 and 7 are fitted with massive shields 19 and 20.

The support 21 serves to protect the axis 22 and the disks from deflection during the branding process.

A ratchet 23 is mounted on the collar of the separating disk 15, which is connected to the disk with screws 24 and pin 25.

On ratchet 23 loosely dressed

a lead 26, provided with a latch 27 with a spring 28.

The leash 26 is interconnected by parts 29, 30 and 31 with a die fixed on the press table.

The pitch discs 14, 13, 12, 11, and 10 on the right end face have ten teeth, about 1C1 of each around the circumference of 36; the disk 15 does not have these teeth. On the left ends of the disks 15, 14, 13, 12 and // ostans “v-lena -... with the help of axes 32 dogs 33, and in the slots of the disks there are springs 34, which go from 55 and fix them to the E, position which yo, first “ah. The pawl is higher than the teeth of the adjacent pitch plates and does not touch them during rotation.

In order to reliably lock the discs during their operation and unlock the discs only at the moment of their rotation, a spring-loaded pins system 34, interacting with professional cams of 55 separating discs, is installed in the numerator.

The pins 34 have a trapezoid shape corresponding to the trapezoidal shape of the horn and divider discs and spacers with one cont. 1 and xpa in the strap 36, attached; 101 to the body with screws.

When driving, the press of a press. on which the case / (-ratora is reinforced, disk 15 oud1) is harvested with spring-loaded pin 34, ukrsplenn 1m on bar 36 and H1PH | 1to :. 37, reinforced in the holder 38.

In the initial document, npii to the line of products from a unit, digital disks are set to a bullet position.

When the press ram is raised, the leash 26 takes the swiveling motion, while the catch 27, fixed on the move 26, and in accordance with the invention.

The numerator for an automatic stamp of a metal press press, produced in the form of a rotor made up of a system of digital discs connected by a spring 28 in a concentric manner to the ratchet 23, turns the current one to 36.

When the memory stick is rotated to 36, the digital disk 2 also rotates by 36 and substitutes the digit / for shock and the product is branded with the number 000001.

The eight next turns of the ratchet with the separating disk 15 will cause the digital disk 2 to represent the numbers from two to nine for the brand. At the tenth turn, the dividing disc 15 with the digital disc 2 is set to zero.

When the disc is rotated by the spring 34, the dog 55 does not touch the teeth of the adjacent disk 14 with its head and only at the tenth turn the head of the dog 55 passes the cam 39, abuts the tooth of the disk 14 and carries it along.

In this case, the disk 14 rotates PA 36 and, being connected to the digital disk 3, rotates it, putting the number 1 under the branding and the product branding; 1m. 000010.

The dog 55, the cam 39, pulls the spring 34 into the first burner 1e and frees the tooth of the dividing disk 14.

A second full turn is accomplished, the split disk 15 will again move the dog 55 under the cam 59 rg the dog will capture the second tooth de. There is a virtual disk 14. Both delnpie dpsky 15 n 14 are rotated by 36, and with them digital dmsky. and 5. Izde.lne zaklemit with the number 000020 n. d.

In this way, the followers of the number 000001 to 999999 will be stamped, with the separating disk 15 with the digital disk 2 giving “units, the separating disk 14 with the digital disk 5 giving“ ten, separating 71, the claim 13 with the digital disk 4 giving "Hundreds, etc.

Knitted sleeves with dividing discs and ratchet mechanism, characterized in that, in order to reliably lock the discs during operation and unlock the discs only at the moment of their rotation when substituting the next digit for impact, the system used springs and spring pins, which are x-shaped and have specialized cams. and a slot of 1 .1 disks, and the ratchet mechanism of the numerator is connected to an iri press matrix of a hinged leash with a spring-loaded end piece trim.
