Description

In FIG. 1 shows a longitudinal vertical section of the proposed machine for the manufacture of drawing buttons; FIG. 2 is a top view, FIG. 3 is a transverse vertical section of the machine; FIG. 4- punches, figs, 5-section along the line AB in FIG. 1, fig. b and 7-part matrix table with crimp pads, in vertical and horizontal sections; FIG. 8-10 are sections along the AiB, CD and EF lines in FIG. b, which clarify the work of the crimping pads; FIG. 11 and 12 parts.

The proposed machine consists of a frame, a mechanism for extruding, crimping, throwing out a button and for mechanical feeding of material, as well as parts transmitting movement.

The bed consists of two parts: upper and lower, which are bolted together. Table 1 is screwed to the bottom of the frame with screws (not shown in the drawing), which serves to support the material. The bed is provided with windows 24, 25, 26, 27 and 28 serving to assemble and lubricate the machine.

The mechanism for squeezing, crimping and ejecting a button consists of a matrix 2, which rests on disk 3 and is held by disk 4; the disk 3, which serves as the base and enters the shoulders and into the recess of the bed, to which is screwed with screws L; punches 11 and 12, of which the first is intended to extrude buttons and the second to form a tongue; the movable table 31, deflected by the spring 32 and returning to the initial position with the help of the lever 33 and the grip 34, on which the lever 21 presses; crimping pads b, with ring 5 driving them, receiving movement from the rod 23 and fitted with; notches; a sliding plate 7, consisting of two halves, used for stamping the stamp on the button and throwing it out; pushing the plate 7 and sliding its ring 8 with cuts, receiving movement from the ring 5 with the help of part 9; and a spring dog 10 fixed to the sliding plate 7 and serving to periodically grab and feed the material; its end is from the axis of the punches at a distance equal to:

J d - {- 4 mm or mm

(where d is the dia. button). To guide the sheet of iron moved by the pawl 10, there is a bar 37, which can be moved along.

it is fixed and fixed with pins 38, which enter the holes, which are located at a distance equal to uf- | -2 mm from each other (y e d-dia. of the button).

The parts driving the machine consist of a shaft 13, a cam disc 14 with a roller 15, levers 16 and 17, rods 18 and 19, levers 20 and 21, and t r 22 and 23. T he ha 23 is connected to ring 5 and . Lever 17 with bearings 29 and 30 having spherical surfaces.

Connecting nuts 35 and 36 are used to change the stroke of the punches, which is needed to control the pressure during the imprint of the stamp. The levers 20, 16, and 17 are fixed on the centers, which makes it possible to quickly replace the parts that have been operated and eliminates the development of the axles.

The buttons are manufactured as follows: after squeezing the button circle, the punch 11 moves it to the sliding plate 7. The punch 11 moves toward the punch 11 and, pushing the tab, bends it, after which both the punch return to its original position, and the punch 12 lags a little late. The punching is followed by a crimping of the button tongue, for which two crimping pads 6 move against each other in the recess of the base 3. The tongue is compressed from all sides, which causes it to obtain an elongation, a circular cross-section and a pointed end. During the reverse movement of the crimpers, the button tongue will receive a rotational movement, which makes its shape improve and the surface smoothes. At the end of the crimping operation, the plate 7 is moved apart and the button falls on the movable table 31, which is deflected to the side during operation of the punches, which are driven from the cam disc 14, is seated, on the shaft 13, and the gun is 11-driven. 22, 20, 18 and 16,

and the punch is 12-thru levers 21, 19 and 16.

The machine is intended for the manufacture of drawing buttons in the amount of about 100 pcs. in 1 minute, the material for which can be roofing iron and sheet iron trimming of appropriate thickness (about 0.5 mm). When exiting the car, the button only needs to give it a smooth and shiny surface. The material feed is automatic.

The subject of the patent.

A machine for the manufacture of drawing buttons, characterized by the cumulative use of: a) two punches 11 and 12, each set in motion through its system of levers from one cam disc 14 sitting on the shaft 13, of which the punches 11, designed to extrude the circles of buttons, is located on top of the matrix table, and puncheson 12, which works to form a tongue, is on the bottom of the table, b) a matrix table with matrix 2 and crimp, equipped with cutouts to form a conical shape with tabs b (Fig. 6), driven by a rotating with periodically back and forth and a slotted ring 5 (fig. 1, 2), connected, in addition, with another ring 8 (fig. 3, 5) with the same cut, for the purpose of sliding or sliding, halves of the plate 7 for stamping the stamp on the button and throwing it out, c) of the spring dog 10 mounted on one of the halves of the expanding plate 7 for periodically gripping and feeding the material as the plate moves apart and d) of the movable table 31 (Fig. 3), in order to retract the buttons falling on it, located under the matrix table and connected in its movement with the ram 12 slider.
