Description

Vertical high-efficient mould frock of forging of duplicate gear part

Technical Field

The utility model relates to a forge the field, specifically a duplicate gear part is vertical forges and uses high-efficient mould frock.

Background

The dual gear is that two gears are connected into a whole, the gear is called as a slipping gear in a gear train, and different gears between two shafts are meshed by the sliding of the gear on the shaft, so that the rotating speed and the speed of an output shaft are changed, and the purpose of speed regulation is achieved.

In order to ensure the coaxiality between two gears of the dual gear, an integral forming processing mode is generally used. The method comprises the steps of obtaining a cylindrical forging blank with a corresponding size through conventional vertical forging, machining a groove between two gears, and finally performing finish machining on the duplicate gear. This manufacturing method has the following disadvantages: 1) because of the structural characteristics of the product, the grooves cannot be forged by conventional vertical forging and can only be compensated by subsequent machining, so that the utilization rate of raw materials is greatly reduced; 2) the groove is machined, so that the machining time is greatly increased, and the cost of the product is increased; 3) workers need to be arranged to machine the forging blank, and the labor management cost is increased.

The technical scheme is as follows: the utility model provides a pair gear part vertical forging is with high-efficient mould frock, mould structure on lower mould structure, first mould structure and the second, mould structure sets up directly over lower mould structure on first mould structure and the second side by side. In the forging process, the metal blank is placed into a cavity formed by the lower die structure, the first upper die structure and the second upper die structure for forging, and after the forging is completed, the first upper die structure and the second upper die structure are respectively removed from the lower die structure. All the structures cooperate with each other to finish the vertical forging work of the duplicate gear part.

Further, mould structure is the same on first mould structure and the second, first mould structure includes mould, power structure and activity structure of punching a hole, power structure sets up in last mould top, the activity structure of punching a hole sets up at last mould side. During demolding, the power structure drives the upper die to move upwards, so that the movable punching structure is driven to complete rod drawing. When the next forging is started, the power structure drives the upper die to move downwards, so that the movable punching structure is driven to complete the reset operation. The power structure can select a cylinder or a motor. The rod drawing and resetting actions of the movable punch rod can be completed by the up-and-down movement or the rotation action of the upper die.

Furthermore, the movable punching structure comprises a fixing plate, a connecting rod structure and a punch, wherein the connecting rod structure is arranged on the fixing plate, and one end of the punch is connected with the connecting rod structure. The fixed plate is fixed on the upper die, when the upper die moves up and down, the connecting rod structure arranged on the fixed plate drives the punch rod to perform rod drawing and resetting actions, and the punch rod performs groove forging and pressing on the metal blank through the pressing of the pressure structure during forging.

Furthermore, the connecting rod structure comprises a first rod, a second rod, a first shaft end cover and a second shaft end cover, wherein the second rod is connected with the first rod, the first shaft end cover is arranged at one end, far away from the second rod, of the first rod, and the second shaft end cover is arranged at one end, far away from the first rod, of the second rod. The first shaft end cover and the second shaft end cover prevent the connecting rod structure from falling off from the fixing plate or the punch rod when moving.

Further, the angle between the first rod and the second rod is 120-150 degrees. The angle between the first rod and the second rod is set according to the depth of the groove between the two gears of the duplicate gear, so that the impact rod cannot interfere in demolding.

Further, a sealing structure is arranged between the first upper die structure and the second upper die structure. The upper die is divided into a first upper die structure and a second upper die structure when forging, so that the metal blank comes out from between the two upper dies in the forging process.

Above-mentioned technical scheme can find out, the utility model discloses following beneficial effect has: 1) through continuous optimization and improvement of the die tooling of the product, the die division development of the module at the groove of the upper die can be realized when the product is demoulded, so that the problem that the product cannot be demoulded is solved; 2) the groove structures are cast together when the duplicate gear is forged, so that the utilization rate of raw materials is improved; 3) the subsequent grooving machining process is reduced, the working efficiency is improved, and the manual management cost is reduced.
