Description

Technical Field

[0001] The present invention relates to the technical field of upsetting dies, and in particular to an automated upsetting die with a supporting mechanism and a use method thereof. Background Art

[0002] Upset is a crucial step in the blade die forging process, which improves the performance of the forging while ensuring that the forging reaches the required shape and size. Traditional upset is mostly manual operation, in which the bar is clamped and positioned manually by a clamp. With the trend of transformation to automation in the industry, the stability of bar placement has become a core issue in realizing upset automation. In the process of automated upset, the deformed part of the bar is suspended outside the clamping part of the die and cannot obtain effective support, causing the bar to fall, which is the key to restricting the realization of upset automation. This application aims to solve the stability problem of the bar after placement by adding a bar support mechanism in the die during the automated upset process. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem of bar falling due to lack of manual assistance and stable support after the manipulator places the bar in the automated upsetting production line, thereby realizing continuous automated upsetting to produce qualified upsetting parts.

[0004] The present invention provides an automated upset forging die with a support mechanism. During automated upset forging, the bar 5 is placed in the upset die by a robot. After the die is closed, a portion of the bar 5 is clamped, and the remaining portion is deformed by the sliding die portion. When the deformed portion of the bar 5 reaches a certain length, the center of gravity of the bar 5 is outside the clamping portion of the die. After the robot is placed and before the die is closed, the bar 5 will become unstable and fall, causing the entire automated production process to be unable to proceed. The invention provides effective support for the suspended portion after the bar 5 is placed, providing favorable conditions for the subsequent die closure. At the same time, according to its own structural characteristics, it is pushed away when the sliding portion of the die moves, which does not affect the upset forging. At the same time, after the sliding portion is moved out, the weight of the support bracket 3 provides a tumbler effect to automatically reset, providing support again for the next time the robot places the bar 5.

[0005] Structural assembly instructions:

[0006] The bracket shaft 2 is assembled in the support bracket 3 by inserting it from the φ3.3 hole to form a support mechanism;

[0007] The support mechanism is assembled in the functional groove of the lower mold 6 of the female mold. The assembly method is that the bracket shaft 2 is mounted in the grooves on both sides of the functional groove, and the right vertical surface of the support bracket 3 is attached to the right side of the functional groove, ensuring that the support bracket 3 can rotate freely when pushed from left to right by hand. After the force of the hand is withdrawn, the support bracket 3 can be automatically reset by gravity, and the right vertical surface is limited by the right side of the female mold to ensure that the support bracket 3 returns to a vertical state.

[0008] A method for using an automated upset forging die with a support mechanism: the upper vertex of the support bracket 3 is aligned with the lower surface of the die clamping surface. To ensure safety, the support bracket 3 is 1 mm lower than the clamping lower surface. After the bar 5 is placed, it is supported by the support bracket 3 and the female die. During operation, the female die upper die 4 is closed downward with the female die lower die 6, clamping the bar 5. The punch 1 feeds from left to right, pushing the support bracket 3 to rotate clockwise around the bracket axis 2, while squeezing the bar 5 into a gathered shape in the die. After the stroke is completed, the punch 1 withdraws from the original path, the support bracket 3 automatically resets to an upright state, the upper die 4 resets upward, and the bar 5 is taken away by the robot, completing an automated upset forging process.

[0009] Advantages of the present invention:

[0010] The automated upsetting die with a support mechanism and its use method described in this invention enable automated upsetting of workpieces with unstable bar stock placed on the die clamping portion, effectively ensuring the quality, feasibility, and stability of automated upsetting. This solves the problems of labor waste and low efficiency caused by the inability to stabilize material discharge during automated upsetting.
