Description

The preset invention is a magnetic-impulse installation for riveting with the use of heating.
U.S. Patent No. US1362934 describes a stationary riveting machine using the pulse - magnetic drive. The principle of working of the magnetic-pulse driver for riveting is based on the conversion of magnetic field energy of the inductor into kinetic energy of a moving beater, which claps the rivet shank with a single hitting.
The polish patent No. 359889 is well-known a tubular rivet with a core and a single-riveting method, especially sheet metal. The tubular rivet with a core is equipped with a tubular body with a flat surface on one of its endings and a flange on the other ending, and with core with shank, which is placed in the body, provided with head on one of its endings, touching the end of the body with a flat surface. The shank of the core is provided with a weakened area, located close to the conical surface between the outer surface of the head and the shank of the core, which causes the appearance of the axial compound force which pulls the shank of the core, pressing the body of rivet and a radial compound of the force, expanding the endenig of the rivet body. The head of the core has an outer diameter bigger than the outer diameter of the rivet body by 4% to 9%. The present invention also provides a method of one-sided riveting, in particular sheet metals with the help of a tubular rivet, characteristic in that, the opening in the riveted sheet metals, on the inaccessible side to the operator, is provided with a conical widening, into which the ending of the rivet body is pressed forming rivet point, which does not protrude from the sweet metal surface.
The polish patent No. 345965 presents a device which is well-known to one-sided riveting equipped with a set, tearing the core of rivet, placed in the body of the head of the device, in combined with a hydraulically activated piston which tears the clamping sleeve, surrounding clamps, clamping the core of rivet, pressed against the clamping piston by means of a clamping sleeve. Between the clamping piston and the tearing piston, there is pressure chamber, connected with the port of compressed air by the means of a control unit.
From the polish patent No. 377909 is well-known a riveting head. The present invention is the riveting head, forming riveted joints in a rotary manner for inseparable joining of parts through the use of an external drive unit for rotary and advancing motion to exert pressure of the punch. The riveting head is provided with a body in the form of a cylinder with a grip, inside which the punch is seated eccentrically relative to the longitudinal axis, under the angle α within the range of 4 ÷ 6°, optimally under the angle of α = 5°. The punch is supported in a rotational manner on a needle rolling bearing and lengthwise on a thrust spherical component , and on the face side of the body it is closed with a seal and a seating ring.
From the international patent No. WO 2013/053350 A1 is well-known the invention relating to the realization of many riveted joints along the surface of the processing object, in particular a riveting device, consisting of a tooling device which is controlled by the control data of tool, for forming rivets with a conical head in the openings of the processing product, the openings and head are formed to adjust rivets with the conical head, through the use of programmable controlling device for transmitting data which control the tool for tool device and an optical measuring device for optical detecting of surface of processing object and for providing data to sensor. In order to ensure the quality and durability during the rivet connection through the use of a rivet device, the control device is configured according to the invention in order to evaluate the sensor data, to obtain the geometrical data which comprise at least one geometrical parameter which is a conical opening that has already been formed, and depending on the result of the evaluation of geometrical data, if necessary, it is allowed to carry out the correction of control data of tool for later formulation of conical endings.
From the international patent application No. WO 2007/090682 A2 is well-known a riveting gun and a device for installing the rivet. The gun consists of the head of the rivet, a rivet with a flange at one ending and a tip of rivet at the other end. The body of the rivet has a cavity in the shape of the opening on thesection of the sleeve. As the other riveting guns, this gun carries out shot about percussive activity with the help of its end of rivet to the opening in two sheets, which must be connected with itself, until the flange of rivet sits down on the upper surface of a front upper layer.
From the international patent application No. WO 03/061869 A1 is well-known an automatic device for cutting rivets, which consists of a matrix with a central mandrel, taking the hollow part in the part of limb with automatic cutting of rivet, the body of matrix has a sunk part for directing the deformation of the ending of limb for the automatic cutting of rivet in the radial external direction, formed on the external peripheral part of the center mandrel, wherein the center pin and the body of matrix are movably connected to one another along the direction of the axis of the mandrel facing the punch, and the spring of panel, where the aliging mandrel is moving against the body of the nozzle so that the automatically cut rivet is pressed by the punch, is carried out at sharp parts, and the tip of the piercing of limb starts clamping an element on the receiving side, through the spindle, it is possibile to bring into contact with the side surface of the tightened matrix element on the receiving side, the limit of direction of moving of pointed elements can be mitigated or eliminated.
The purpose of the invention is to provide a new and extended technological capabilities, magnetic-pulse installation for riveting with heating.
Magnetic-pulse installation according to the invention is characterized in that the clamp with the drive and contacts for heating rivet are placed on the sling of the device consisted of: battery connected with the unit of heating control, base, rotary table, counterbalance stand, rotary bracket, sling, the clamp with the propulsion and contacts for heating rivet, where sling rotate in all directions and move vertically. The rivet terminals are provided with a pulse drive and a control system of temperature of heating the rivet.
In place of the battery the AC adapter is used.
The rivets are welded with heating and / or cold.
In order to expand the technological possibilities of installations of a similar type, it is proposed: placing clamps on the sling with the possibility of rotation in all directions and vertical movement, and installing on the sling, the contacts for heating of clapped metal.
Processes of riveting on the pulse-magnetic installation are performed in semiautomatic mode, characterized by high stability of selected parameters and not depending much on employee's qualifications.
The magnetic-pulse installation is described in the following drawings in which:

Fig.1 construction of magnetic-pulse installation,
