Description

I

This invention relates to riveting operations.

A two-sided flare machine for riveting heads on a rod is known, comprising two spindle heads mounted coaxially and opposite to each other in a guide frame with the possibility of reciprocating movement from the drive and equipped with a carbide-expanding flare tool, as well as a mechanism for installing riveted parts.

However, the known machine does not provide high performance.

In the proposed machine, the drive of spindle heads is made in the form of two-arm levers mounted on the frame and interconnected through the yoke, each of which is connected to the spindle head, and a copier in contact with the yoke mounted to the eccentric mounted on the drive shaft, and with the footswitch provided in the machine, and the installation mechanism of the riveted parts is made in the form of a fixed stop and a slider located on the machine bed coaxially relative to each other and perpendicular to the axis azvaltsovki, wherein the fixed stop is formed as a housing with disposed therein movable clamps actuated

from the carriage pivotally fixed to the body of the stop, and the slide is made in the form of a spring-loaded body with a roller mounted in a new roller in contact with the drive's copier.

FIG. 1 given the general scheme of the machine; in fig. 2 - spindle head; in fig. 3 and 4 - the mechanism of installation of riveted parts; in fig. 5 and 6 - drive spindle heads.

The machine contains two spindle heads 2 and 3 mounted on frame I with the possibility of reciprocating movement along guides 4 from the drive 5. Each spindle head is equipped with a flare tool 6 with carbide plates 7, while the tools rotate in the opposite direction. On the frame installed mechanism 8 installation of riveted parts.

The drive 5 of the spindle heads 2 and 3 is made in the form of 9 two-arm levers 10 and II mounted on the frame and connected to each other through the yoke, each of which are connected respectively to the spindle

head 2 and 3, while two shoulders levers are adjustable by means of a screw 12.

The beam 9 is in contact with a cam 13, connected via a cable 14, with an eccentric 15 mounted on a drive shaft 16, which is connected to the electric motor via an intermediate drive 17 and connected to a control pedal 18.

The installation mechanism of the riveted parts is made in the form of a fixed stop 19 and a slide 20. The fixed support 19 has a housing with movable latches 21 located in it, driven from a carriage 22 with a handle 23, the carriage is hinged to the support 19, and equipped with a pusher 24, acting on latches 21, as well as lodgments 25 with restraints 26.

The slider 20 is made in the form of a spring-loaded housing with a roller 27 mounted therein, in contact with the cam drive 13 of the spindle heads. A reducer 28 is mounted on the drive shaft 16, a turn on coupling half 29 with a turn on finger 30, and a coupling half 31.

The machine works as follows.

After switching on the electric motor, the handle 23 of the carriage 22 is lowered to the lower position, at which time the pusher 24 moves the latches 21 until it touches the slide 20, and the cradle 25 with the stops 26 occupy the upper position at which the riveted parts (hinge bars) connected by a rod, placed on the cradle carriage.

When the handle 23 is rotated to the upper position of the part, it enters the work area, supported by clamps 21 and limiters 26.

When the control pedal 18 is pressed, the coupling half 30 connects the half coupling 29 and 31, the eccentric 15 lowers the lever 32 pivotally connected to the tension 14 of the copier 13.

The copier 13 transmits the force through the handle 23 to the slider 20, which produces clamping of the hinge parts.

Upon further movement of the copier 13 down slider 20 is fixed, and the beam 9 transmits forces to the approach of the spindle heads 2 and 3 through the two shoulders levers 10 and 11.

Instruments rotating in opposite directions are in contact with the rod.

heat the ends and roll them, giving the heads the desired shape.

At the end of one revolution of the eccentric 15, the pedal 18 separates the half couplings 29 and 31, the springs 33 return the tools and two shoulders levers 10 and 11 to their original position, and by reinforcing the spring 34 the copier 13 releases the slider 20, which springs back to its original position.

Released assembled product - the loop falls into the receiver of the finished product.

Subject invention

A machine for double-sided expansion of the sealing heads on the rod, containing two spindle heads, mounted in coaxial bed guides and opposite to each other with the possibility of reciprocating movement from the drive and equipped with carbide-plate spreading tools, as well as a mechanism for installation of riveted parts, differing from that, in order to increase productivity, the drive of the spindle heads is made as mounted on the frame and interconnected through the arm of the two shoulders, each on which is connected to the spindle head, and in contact with the arm of the copier connected through the puller to the eccentric mounted on the drive shaft, and with the inclusion ice, 1 provided in the frame, and the mechanism for installing the riveted parts is designed as stationary stop and shaft, located on the machine bed coaxially one of the other and perpendicular to the axis of the flaring, in this case the fixed stop is made in the form of a body with movable latches located in it, bring bubbled from the carriage, scharnirno abutment fixed on the body, and the slider is formed as a spring-loaded housing with a smontirovaiigm roller therein, in contact with the drive cam.
