Description

Technical Field

[0001] This application relates to the field of punching processing technology for mechanical parts, specifically to a punching die. Background Technology

[0002] When machining mechanical parts, it is necessary to punch riveting holes on their surfaces to facilitate subsequent riveting with other mechanical parts. For long mechanical parts with L-shaped cross-sections, such as some longitudinal beams and stringers of aircraft, punching is required on two different faces. If conventional punching methods are used, the angle of the punching die and punching machine must be changed after punching one side before punching the other side, which is quite troublesome. If only one punching die is used, when the connecting corners of the L-shaped mechanical parts are rounded, it is difficult for the punching die to fit tightly against both inner surfaces of the mechanical parts, affecting the punching effect. Furthermore, when the punching points are located at different positions in the width direction of the two plates of the mechanical parts, different punching dies need to be changed, affecting the punching efficiency.

However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figure 1 As shown, this embodiment provides a punching die mechanism, including a movable plate 1 and a die chamber 2.

The first mold hole 21 and the second mold hole 22 are used to cooperate with an external punching machine for punching. The punching machine can be manually held or mechanically positioned, and the specific punching method is existing technology, so it will not be described in detail here.

By moving the first slider 12, the second slider 14, and the moving plate 1, the first mold hole 21 and the second mold hole 22 are sequentially made to coaxially contact the punching points on the mechanical component, thus punching the punching points sequentially.

[0025] Preferred, such as Figure 1 As shown, the punching die mechanism provided in this embodiment also includes a first electric lead screw 3 arranged along the horizontal direction. The first electric lead screw 3 is threadedly engaged with a first mating block 31. The moving plate 1 is connected to the first mating block 31. The first electric lead screw 3 drives the moving plate 1 to move along the horizontal direction.

[0026] Preferred, such as Figure 1 and Figure 2 As shown, the bottom of the mold chamber 2 is provided with two first positioning blocks 23, and each of the two first positioning blocks 23 is provided with a first positioning strip 24 directly below it. Both first positioning strips are axially movable along the first slide rod 11. The two sides of the mold chamber 2 are provided with second positioning blocks 25. Each of the two second positioning blocks 25 facing the rear end face of the mold chamber 2 is provided with a second positioning strip 26. Both second positioning strips 26 are axially movable along the second slide rod 14. Springs 15 are coaxially sleeved around the second slide rod 14. The two ends of the springs 15 are respectively connected to the rear end face of the mold chamber 2 and the second slider 13. The springs 15 are always in a stretched state. With this design, under the action of gravity, the first positioning block 23 will always be in contact with the first positioning strip 24. Under the action of the springs 15, the second positioning block 25 will always be in contact with the second positioning strip 26. By moving the first positioning strip 24 and the second positioning strip 26, the movement of the mold chamber 2 in the axial directions of the first slide rod 11 and the second slide rod 14 can be controlled.

[0027] Preferred, such as Figure 1 and Figure 2As shown, a second electric lead screw 27 is provided between the movable plate 1 and the mold chamber 2. The second electric lead screw 27 is axially arranged along the second slide bar 14. Connecting folding rods 28 are connected to both sides of the outer shell of the second electric lead screw 27. The connecting folding rods 28 are respectively connected to two second slide bars 13. The drive shaft of the second electric lead screw 27 is threadedly fitted with a second mating block 29. The second mating block 29 is connected to a linkage plate 210. The first positioning strips 24 are all connected to the linkage plate 210. The ends of the two second positioning strips 26 extending out of the front end face of the mold chamber 2 are connected by a linkage. A third electric lead screw 212 is vertically provided on the upper surface of the movable plate 1. The third electric lead screw 212 is threaded with a third mating block 213. The third mating block 213 is connected to one of the second positioning bars 26. A third sliding rod 214 is vertically provided on the upper surface of the movable plate 1. A third slider 215 is slidably sleeved on the third sliding rod 214. The third slider 215 is connected to another second positioning bar 26. A second electric lead screw 27 is used to drive the first positioning bar 24 to move, and a third electric lead screw 212 is used to drive the second positioning bar 26 to move.

[0028] Preferred, such as Figure 1 and Figure 2 As shown, a mounting bracket 16 is provided between the two second sliders 13. The two ends of the mounting bracket 16 are respectively connected to the two second sliders 13. A first linear cylinder 17 is provided on the mounting bracket 16. The first linear cylinder 17 is axially arranged along the second slide rod 14 and its drive shaft faces the rear end face of the mold chamber 2. The drive shaft of the first linear cylinder 17 is coaxially connected to the first push plate 18. A second linear cylinder 19 is vertically connected to the upper surface of the moving plate 1. The drive shaft of the second linear cylinder 19 is arranged facing the lower surface of the mold chamber 2 and is coaxially connected to the second push plate 110. During operation, when the punching points are not at the same position in the width direction of the two plates of the mechanical part, the first positioning strip 24 and the second positioning strip 26 can be moved to a certain position first. At this time, the first die hole 21 and the second die hole 22 are respectively connected to a set of the mechanical parts. The punching points on the two plates of the component are aligned in the width direction. When the moving plate 1 moves to the designated position, the first pushing plate 18 and the second pushing plate 110 are driven to move by the first linear cylinder 17 and the second linear cylinder 19 respectively. The first pushing plate 18 and the second pushing plate 110 push the mold chamber 2 at the corresponding moment so that the mold chamber 2 contacts the mechanical component to cooperate in punching. When punching another set of punching points on the two plates of the mechanical component, the positions of the first positioning strip 24 and the second positioning strip 26 are adjusted, and the above steps are repeated. With this design, it is not necessary to move the first positioning strip 24 and the second positioning strip 26 for each punching. The first positioning strip 24 and the second positioning strip 26 only perform positioning functions, which further improves the punching efficiency.

[0029] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
