Description

Boss forging tool

Technical Field

The utility model relates to a forge technical field, especially relate to the frock field that uses when forging, specifically indicate a boss forges frock.

Background

Forging is a common processing mode, can improve the compactness of a workpiece, and ensures that the workpiece has good mechanical properties. The forging tool is an indispensable part during forging, and the structural design of the tool directly influences the forging efficiency. In the product of my company's production, there is a forging for wheel body, and this forging is two-sided boss structure to the boss is located two-sided border position, and the mode that adopts at present is that the both sides boss is respectively at two forging station processing, causes production efficiency to be lower.

Disclosure of Invention

The utility model discloses to prior art's not enough, provide a boss and forged frock, realized forging the shaping to two-sided boss forging at a station.

The utility model is realized by the following technical scheme, a boss forging tool is provided, which comprises an upper die fixedly connected with a press head and a lower die which is positioned under the upper die and is fixedly arranged, wherein the top surface of the lower die is provided with a vertical downwards extending forging groove, the bottom of the forging groove is provided with a first boss which extends upwards, the first boss is in a round platform shape with a small upper part and a big lower part, and a first annular groove which is closed along the circumferential direction is formed between the first boss and the side wall of the forging groove; the lower extreme of going up the mould is equipped with and forges the guide post of groove adaptation, and the lower extreme of guide post is equipped with big-end-up's second boss, and the lateral wall upper end of second boss forms along the closed face of forging on of circumference with the lateral wall lower extreme of guide post, on forge and form the second annular between the lateral wall of face, second boss and the lateral wall of forging the groove.

This scheme is when using, puts into the work piece blank and forges the groove, utilizes the press pressure head to drive and goes up the mould and reciprocate along forging the groove, accomplishes and forges the operation, provides the guide effect through the guide post, forms first annular through setting up first boss to forge out the bottom surface boss of work piece, through setting up the second boss and form the second annular at the guide post lower extreme, with the boss at forging out the work piece top, realized the two-sided boss shaping of same station, improved production efficiency.

As optimization, stamp punching holes which penetrate through the top surface of the first boss to the bottom surface of the lower die along the vertical direction are formed in the lower die. This optimization scheme smashes the punching through the setting, after forging the completion, conveniently punches the ejecting groove of forging of work piece from the below through smashing, has shortened and has got a time, has further improved production efficiency.

As optimization, the tamping hole comprises a cylindrical hole and a conical hole which is arranged above the cylindrical hole and has a large upper part and a small lower part, and a conical tamping rod which is penetrated from top to bottom is arranged in the conical hole; the outer surface in the lower die is further provided with a jack which transversely penetrates through the tamping hole, a force application rod penetrates through the jack, and a guide inclined plane facing the jack is arranged at the lower end of the tamping rod. When the optimized scheme is used, the force application rod is pushed along the transverse direction, so that thrust is applied to the guide inclined plane, the upward component force is utilized to enable the tamping rod to move upwards to eject the upper end of a workpiece out of the tamping groove, the operation is more convenient, and the workpiece does not need to be drilled below equipment to be tamped and taken; when the application of force pole was taken out, the ram whereabouts utilizes the lateral wall of circular cone hole to support the ram, and simple structure prevents that the ram lower extreme from falling below the jack when the application of force pole was taken out to reduced the ram move up the time and the frictional resistance between the pore wall.

Preferably, one end of the force application rod facing the guide inclined plane is in a circular arc shape. The setting of this optimization scheme makes the application of force pole pass through the circular arc and guide the inclined plane contact, has improved the reliability that the application of force pole upwards pushed the ramming pole.

Preferably, the upper end of the guide inclined plane is lower than the arc top of the jack by 1/5 the diameter of the jack. This optimization scheme's setting has increased the displacement of application of force pole after with the ramming pole contact to prolonged the displacement distance of ramming the pole, avoided simultaneously because the guide inclined plane transition leans on down and hinder the application of force pole and remove.

Preferably, the included angle between the guide inclined plane and the horizontal direction is 15-30 degrees. The guide inclined plane angle setting of this optimization scheme has guaranteed the reliability that the ramming pole removed.

Preferably, the outer surface of the lower die is provided with a clamping groove which is closed along the circumferential direction, and the cross section of the clamping groove is trapezoidal. This optimization scheme is through setting up the centre gripping groove, and it is fixed to conveniently carry out horizontal centre gripping to the lower mould, sets up the cross-section in centre gripping groove into trapezoidal, makes things convenient for horizontal clamping device and lower mould to break away from, has improved the lower mould and has changed efficiency.

The utility model has the advantages that: the lower die is provided with the first boss to form the first annular groove, the upper die is provided with the second boss to form the second annular groove, so that blank materials enter the first annular groove to form the bottom boss of the workpiece, and the blank materials enter the second annular groove to form the boss at the top of the workpiece, thereby realizing the double-sided boss forming at the same station and greatly improving the production efficiency; through the tamping rod and the force application rod, the upper end of the workpiece is conveniently ejected out of the forging groove, so that the workpiece taking-out efficiency is improved, and the production efficiency is further improved.
