Description

Technical Field

[0001] The utility model relates to a continuous stamping die for a guide ring bushing for a vehicle. Background Art

[0002] A guide ring is provided at each end of the automobile chassis support rod. In order to make the guide ring directly contact with other components, a bushing needs to be installed on the guide ring.

Since the current bushing stamping mostly adopts a single-die structure, that is, the forming die is only responsible for the generation of the main shape, and the raw material cutting and contour forming must be completed in another blanking die, this means that the sheet material must be collected after the initial forming in the blanking die and manually fed into the forming die in turn, which makes the operation steps more cumbersome, and repeated feeding and discharging wastes a lot of time, which leads to low processing efficiency. In addition, it will also lead to high labor costs due to reliance on manual operation, which needs further improvement. Utility Model Content

[0048] Working principle:

[0049] First, the top plate 1 is driven to repeatedly reciprocate up and down at a certain frequency to drive the first base plate 31, the first seat plate 32, the first guide plate 33 and the first pressing plate 34 in the first punching unit 3 to move synchronously, and at the same time drive the second base plate 41, the second seat plate 42 and the second guide plate 43 in the second punching unit 4 to move synchronously, and then use the gap of the top plate 1 to push the steel plate 5 horizontally from left to right to the top of the first support plate 36, and then continue to feed in the direction of the second support plate 46 at a certain speed. When the first pressing plate 34 and the second pressing plate After 44 contacts the first support plate 36 and the second support plate 46 respectively, the first pressure plate 34, the first guide plate 33, the second pressure plate 44 and the second guide plate 43 will all retract upward for a distance to allow the first seat plate 32 and the second seat plate 42 to continue to move downward for a certain distance; when the top plate 1 moves upward to allow the first pressure plate 34 and the second pressure plate 44 to leave the first support plate 36 and the second support plate 46 respectively, the first pressure plate 34, the first guide plate 33, the second pressure plate 44 and the second guide plate 43 will all move downward and elastically reset. The above structures and principles are all prior arts.

[0050] When the steel plate 5 moves to the punching module, the top plate 1 drives the first seat plate 32 to move downward, so that the lower ends of the two punching columns 37 pass through the steel plate 5 and are respectively inserted into the two guide holes 3111 on the seventh auxiliary block 311, thereby punching out two round wastes 58 on the steel plate 5; thereafter, the top plate 1 will move up and reset; after repeating the above steps, the two punching columns 37 will form two circular holes 59 on the steel plate 5 in sequence at the same distance interval; in the subsequent feeding process, when the top plate 1 moves downward each time, the two positioning pins 6 in each positioning pin combination will be respectively inserted into the two circular holes 59 to play an accurate positioning role.

[0051] When the steel plate 5 moves to the first punching module, the top plate 1 drives the first seat plate 32 to move downward again, and the lower end of the first punching column 38 passes through the steel plate 5 and is inserted into the X-shaped punching cavity 3121 on the first auxiliary block 312, and then the X-shaped waste materials 51 are punched out one by one on the steel plate 5 in the same way.

[0052] When the steel plate 5 moves to the second punching module, the lower ends of the two arc-shaped punching pieces 39 pass downward through the steel plate 5 and are respectively inserted into the arc-shaped punching cavities 3131 on the two second auxiliary blocks 313, and then multiple groups of arc-shaped waste materials 52, two in a group, are punched out in sequence on the steel plate 5 in the same way.

[0053] When the steel plate 5 moves to the first forming module, the first forming column 310 moves downward so that its lower end is embedded in the first forming cavity 3141 on the third auxiliary block 314, and then circular cavities 53 are formed on the steel plate 5 in sequence in the same way.

[0054] When the circular sink 53 moves to the shaping module, the shaping column 47 moves downward so that its lower end presses each circular sink 53 into the shaping cavity 4171 on the eighth auxiliary block 417 in turn for shaping.

[0055] When the circular sink cavity 53 moves to the third punching module, the second punching column 48 will move downward so that its lower end passes through the bottom surface of the circular sink cavity 53 and is inserted into the first through hole 4121 on the fourth auxiliary block 412, and each first rack 481 is respectively inserted into a corresponding first rack 481, thereby punching out a rudder-shaped waste material 55 on the bottom surface of each circular sink cavity 53, and a plurality of clamping plates 54 evenly arranged at equal angles along the circumferential direction are formed on the bottom surface of each circular sink cavity 53.

[0056] When each circular sink cavity 53 moves to the flattening module, the flattening column 416 will move downward so that the second through hole 4161 at its lower end is mounted on the outside of the upper end of the model column 418, and each clamping plate 54 is pressed against the top of the second support plate 46 to flatten each clamping plate 54. During this process, each second rack 4181 is inserted into a corresponding second rack 4181.

[0057] When each clamping plate 54 moves to the second forming module, the second forming column 49 will move downward, and then each clamping plate 54 will be bent upward by the cooperation between the conical cavity 491 located at the lower end thereof and the conical head 4141 on the third forming column 414.

[0058] When the circular sinking cavity 53 moves to the third forming module, the sleeve 410 and the fourth forming column 411 will both move downward, and the annular flange 4111 will cooperate with the circular cavity 4151 to form an annular step opening 56 at the opening of the circular sinking cavity 53. At the same time, the lower end of the sleeve 410 will flush the circular sinking cavity 53 away from the steel plate 5 to generate a complete vehicle guide ring bushing 57.

[0059] The utility model combines raw material cutting, contour forming and main shape generation in one mold. The raw material plates only need to be fed in sequence at certain time intervals to obtain the completed vehicle guide ring bushings 57 in sequence. Therefore, there is no need to manually transfer semi-finished workpieces during the process, thereby simplifying the operation steps to save more time, thereby improving processing efficiency and reducing labor costs.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein with equivalents.
