Embodiment Construction
[0021] The four-hammer forging equipment consists of the following: a forging hammer bracket 1 fixed on the upper movable plate 2; a forging hammer bracket 3 fixed on the lower immovable plate 4; two side forging hammer brackets 5, 6; Forging hammers 7-10 on the hammer support; 8 separate guide rods 11 that ensure the power connection between the side forging hammer supports and the upper and lower forging hammer supports; anti-wear sheet 12; anti-friction lubricant transmission system 13. The side forging hammer supports 5 and 6 are centered by the central guide rod 14 according to the upper and lower forging hammer supports 1 and 3. In this state, a central guide rod 14 ( figure 2 ) Or several guide rods such as two 14 ( image 3 )installation. The central guide rod 14 can be installed on the slopes of the side forging hammer supports 5 and 6, and can be placed on one or more planes perpendicular to the longitudinal axis of the equipment. 12 In the central groove composed of si...

The invention relates to metal forming and can be used for forging billets and blanks by means of forging presses and radial-swaging machines. Four dies are mounted on holders which are provided with inclined planes and antifriction plates arranged thereon. The holders of the top and lower dies are kinematically connected to the holders of the lateral dies. Centring guides are mounted on the inclined planes of the top and lower die holders or on the inclined planes of the lateral die holders. They are placed in centring grooves which are formed by the groove walls of the lateral die holders or the top and lower die holders and the side planes of respective antifriction plates. The device also comprises lateral separating guides provided with an F-shaped cross-section. The width of the working face of each die is equal to 0.5-0.9 the width of the supporting surface thereof. The ratio between the total contact area of the antifriction plates of the lateral die holders with the antifriction plates of the top and lower holders in the closed device (S1) and the total area of the projection of the working faces of the lateral dies on the longitudinal symmetry plane (S2) of the device is defined by the formula S1 / S2>=2.5. Said invention makes it possible to extend the service life of the device.
Description
Technical field [0001] The invention belongs to the field of metal pressure processing, namely four-hammer head forging equipment, and is also applied to the process of forging metal ingots and billets by hydraulic forging presses and radial forging machines. Background technique [0002] The invention can be used to produce long shaft products, such as drill pipes, cylinders, central shafts, torsion shafts, rolling mill shafts and other similar products in the machinery manufacturing and metallurgical industries. It can also be used to produce structural steel, stainless steel, heat-resistant steel and non-deformable The steel and alloy casting billets of steel, so as to continue die casting. [0003] There is a four-hammer head forging equipment consisting of two upper and lower forging hammer supports with beveled surfaces, two forging hammer supports on the side with beveled surfaces, and hammer heads on four forging hammer supports. The two forging hammer brackets on the sid...
