Description

The invention relates to the processing of metals by pressure, in particular to equipment for the manufacture of heudes.

The purpose of the invention is to simplify the design and increase reliability.

The drawing shows the kinematic scheme of the nailing machine.

The device consists of an electric motor 1 mounted on a frame, a textronic transmission 2, an eccentric drive shaft 3 with a bevel gear, an intermittently rotating drive rotor with consoles 4 having correct rollers 5. The wire feed mechanism is fixed on the frame of the half ring 6 on one of the the ends of which are made of a software profile in the form of a sinusoidal groove 7. In the latter, a roller 8 of a two-armed lever 9 is placed, which with its other arm using a connecting rod 10 is connected to the wire feed carriage 11, while adjustment of the wire feed length is made by moving the axis-support 12 along the lever 9 fixed on the console 4.

The machine has a work clamping mechanism 13 with a fixed sponge, a sharpening mechanism 14 and segments connected with the respective fixed rings 15 and 16. The ring 15 has a software profile made in the form of protrusions 17 for contacting another roller 8 located at the junction of the two levers a link 18, at one end of which there is a movable sponge 19 of the clamping mechanism, and on the other - another adjustable support 12, designed to compensate for physical wear and the difference in the length of the tool used, as well as spacing ty dia diameters of the supplied wire (at setting).

The inner ring 16, in fact, this is the serrated end, contacts the gear 20 mounted on a roller 21 having a cam disc 22 for contacting the roller 23 of the pointed mechanism 14 and the segments.

To drive the mechanisms for landing the rod head, there is a common planetary gear reducer consisting of gear 24, intermediate gear 25, mounted on a movable carrier, sun gear 26 with eccentrically shifted cavities 27 for installing eccentrics 28 and spring-loaded crackers in them. 29, which are located between the working surfaces of the eccentrics 28 of the drive shaft 3 and the sun gears 26. Each stem head landing mechanism has a pusher 30 for transmitting movement to the punch 31 of the spring-loaded punch the holder 32 and the movement mechanism puansono- holder 32 includes associated with 32 puan- sonoderzhatelem rod 33 with a contact roller 34 for engagement with the projections 35 of the corresponding software profile of the fixed ring 36. The machine 37 has a carrier 25 for gears.

When adjusting the tumbler rollers 29, it is possible to turn the sun gear 26 only in one direction.

The operation of the machine is carried out when the electric motor 1 is turned on by the action of a wire feed mechanism with a carriage 11, a clamping mechanism 13, a pointed mechanism 14 and pieces, as well as a movement mechanism of the punch holder 32 with a punch 31 placed on the console 4 with corresponding fixed rings 6, 15, 16 and 36, whereby the pushers 30 are driven from the outer surface of the toothed chains 24, which act on the pushers 30 of the forming streams using intermediate gears 25 in contact with adjustable forces. centered 28 of the drive shaft 3 through the crackers 29.

If necessary, adjust the machine to another size nails.

The proposed design of the nailing machine significantly increases its reliability, since the physical wear of the teeth of the intermediate gears and pushers is reduced.
