Description

Technical Field

[0001] The utility model belongs to the field of metal stamping, and particularly relates to a stretching die for a long cross beam. Background Art

[0002] There are various parts to be stretched, which are different in the length direction, width direction and height direction. It is necessary to optimize and improve the die according to the characteristics of different parts. For example, a stretching part for providing mobile phone support or decoration is designed on the interior trim panel of a vehicle. As Figure 1 shown, its dimension in the length direction is much larger than that in other directions. If a conventional standard die set is used, although the design is relatively simple, if one piece is designed per die, the processing efficiency is low, and only one piece can be stamped with one feeding. If multiple pieces are designed per die, there will be great resistance during stamping and stretching, and a large hydraulic device is required to drive the die to open and close. Since the cost of large hydraulic devices is relatively high and large hydraulic devices are in short supply in some factories, how to achieve high-efficiency production of multiple pieces per die with a smaller hydraulic device is a major technical problem. Summary of the Utility Model

[0003] Aiming at the above-mentioned prior art, the purpose of the utility model is to provide a more efficient stretching die for a long cross beam.

[0004] The technical solution of the utility model is realized as follows: A stretching die for a long cross beam includes a moving die, a punch, a die cavity, a first long cross beam, a first driving structure and a second driving structure. The first long cross beam is arranged on the punch in the length direction and moves or rotates along with the first long cross beam. Hinge shafts and pressing parts are respectively arranged at two ends of the first long cross beam. The pressing part is directly or indirectly driven by the first driving structure. The hinge shaft is hinged with the moving die so that the first long cross beam can rotate relative to the moving die. The moving die is directly or indirectly driven by the second driving structure to move linearly, and the die cavity is fixed.

[0005] The beneficial effect of such a design is: The driving force of the die during stretching can be reduced by using the lever principle. The longer the first long cross beam is, the more labor-saving it is. In this way, multiple punches and die cavities can be arranged side by side to achieve high-efficiency production of multiple pieces per die. In this way, a hydraulic device with a lower tonnage can be used, the equipment procurement cost is lower, and the average production cost of products can be reduced.

[0006] A long crossbeam stretching die includes a die set, a punch, a die, a first long crossbeam, a first driving structure and a second driving structure. A first long crossbeam is arranged in the length direction of the punch and moves or rotates following the first long crossbeam. Hinge shafts and pressing parts are respectively arranged at two ends of the first long crossbeam. The pressing part is directly or indirectly driven by the first driving structure. The hinge shaft is hinged with the die set so that the first long crossbeam can rotate relative to the die set. The die is directly or indirectly driven by the second driving structure to move linearly. The driving force of the die during stretching can be reduced by using the lever principle. The longer the first long crossbeam is, the more labor-saving it is. In this way, multiple punches and dies can be arranged side by side to achieve high-efficiency production of multiple parts in one die. In this way, hydraulic equipment with a lower tonnage can be used, the equipment procurement cost is lower, and the average production cost of products can be reduced.

[0007] A long crossbeam stretching die includes a moving die, a punch, a die, a first long crossbeam, a first driving structure and a second driving structure. A first long crossbeam is arranged in the length direction of the die and moves or rotates following the first long crossbeam. Hinge shafts and pressing parts are respectively arranged at two ends of the first long crossbeam. The pressing part is directly or indirectly driven by the first driving structure. The hinge shaft is hinged with the moving die so that the first long crossbeam can rotate relative to the moving die. The moving die is directly or indirectly driven by the second driving structure to move linearly. The punch is fixed.

[0008] The beneficial effects of such a design are: The driving force of the die during stretching can be reduced by using the lever principle. The longer the first long crossbeam is, the more labor-saving it is. In this way, multiple punches and dies can be arranged side by side to achieve high-efficiency production of multiple parts in one die. In this way, hydraulic equipment with a lower tonnage can be used, the equipment procurement cost is lower, and the average production cost of products can be reduced.

[0009] A long crossbeam stretching die includes a die set, a punch, a die, a first long crossbeam, a first driving structure and a second driving structure. A first long crossbeam is arranged in the length direction of the die and moves or rotates following the first long crossbeam. Hinge shafts and pressing parts are respectively arranged at two ends of the first long crossbeam. The pressing part is directly or indirectly driven by the first driving structure. The hinge shaft is hinged with the die set so that the first long crossbeam can rotate relative to the die set. The punch is directly or indirectly driven by the second driving structure to move linearly. The driving force of the die during stretching can be reduced by using the lever principle. The longer the first long crossbeam is, the more labor-saving it is. In this way, multiple punches and dies can be arranged side by side to achieve high-efficiency production of multiple parts in one die. In this way, hydraulic equipment with a lower tonnage can be used, the equipment procurement cost is lower, and the average production cost of products can be reduced.

[0010] Further, a second long crossbeam is arranged above the first long crossbeam. One end of the second long crossbeam is hinged with the die set or the moving die and the other end is directly or indirectly driven by the first driving structure. The middle position of the second long crossbeam is directly abutted against the pressing part to drive the pressing part to rotate. In this way, a two-stage lever structure can be adopted to achieve the action.

[0011] Furthermore, the pressing part is provided with rollers that abut against the second long crossbeam. This design can reduce the wear of the second long crossbeam and increase the transmission efficiency.

[0012] Furthermore, multiple punches, dies, the first long crossbeam, and the second long crossbeam are arranged side by side, which can achieve multiple parts in one mold and improve production efficiency.

[0013] Furthermore, a longitudinal beam is provided above the second long crossbeam, and the longitudinal beam is fixed to the first driving structure. In this way, one driving mechanism can drive multiple punches or dies to act simultaneously.

[0014] Furthermore, multiple second long crossbeams are coaxial and form an integral structure. The integral structure has more stable and reliable performance, is not prone to deformation, and the actions are more synchronous, resulting in better product consistency.

[0015] Furthermore, multiple punches are coaxial and form an integral structure, and the product quality of the integral structure is more stable. BRIEF DESCRIPTION OF THE DRAWINGS
