Precision forging mold for workblank of engine connecting rod

Abstract

The invention relates to the technical field of production equipment for engine connecting rods and discloses a precision forging mold for a workblank of an engine connecting rod. The mold comprises abase. A lower module base is fixedly installed in the base, movable holes which are symmetrically distributed in a left-right direction are formed in the lower module base, and the top of the lower module base is provided with a lower mold groove. Slide supporting rods are movably installed in the movable holes, the bottoms of the slide supporting rods are fixedly provided with limit rods, and the bottoms of the limit rods are fixedly provided with limit bases located in the movable holes. The precision forging mold for the workblank of the engine connecting rod has the advantage of providingconvenience for taking out a product. The forging mold has the advantages of being capable of achieving a flat end face and achieving a good formation effect, high in production efficiency and suitable for being applied and popularized. But the forging mold has the defect that during actual use, the workblank is easily stuck in a mold groove of the mold, and the product is not easily taken out.

Description

technical field [0001] The invention relates to the technical field of engine connecting rod production equipment, in particular to a fine forging die for an engine connecting rod blank. Background technique [0002] The connecting rod of the engine connects the piston and the crankshaft, and transmits the force acting on the piston to the crankshaft, converting the reciprocating motion of the piston into the rotational motion of the crankshaft. , connecting rod big head bearing bush and connecting rod bolts (or screws), etc. The connecting rod group bears the gas force from the piston pin, its own swing and the reciprocating inertial force of the piston group. The magnitude and direction of these forces are periodic Therefore, the connecting rod is subject to alternating loads such as compression and tension. The connecting rod must have sufficient fatigue strength and structural rigidity. If the fatigue strength is insufficient, the connecting rod body or the connecting ro...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a fine forging die for an engine connecting rod blank, which has the advantages of being easy to take out the product, and solves the forging die for an engine connecting rod blank proposed in Chinese patent CN201820359811.4. The forging die has The end surface is smooth, the shaping effect is good, the production efficiency is high, and it is suitable for popularization and use. However, when this kind of forging die is actually used, the blank is easy to get stuck in the die groove of the die, resulting in the disadvantage that the product is not easy to take out.
