Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die and cooling structure for a civil aviation seat lock connecting plate. Background Technology

[0002] The production of civil aviation seat lock connecting plates involves a series of processes. In the production of the L-shaped connecting plate, the stamped raw material must first be flanged, and then the flanged material must be bent as a whole. Currently, different molds are used to process the raw material, and the flanged material needs to be sheared before the overall bending process. The use of different molds in these two processes affects processing efficiency. Furthermore, the temperature of the molds inevitably rises during prolonged stamping operations, which affects stamping efficiency and makes the molds more prone to wear. Therefore, we propose a stamping mold and cooling structure for civil aviation seat lock connecting plates. Utility Model Content

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 5 This utility model provides a technical solution: a stamping die for a civil aviation seat lock connecting plate, including a second template 3 and a first template 2. The first template 2 is located above the second template 3. Mounting plates 1 are installed on the sides of the first template 2 and the second template 3 that are far apart from each other. The first template 2 and the second template 3 are respectively set in a stepped manner with respect to the edge of the mounting plate 1. The first template 2 and the mounting plate 1, as well as the second template 3 and the mounting plate 1, are all integrally formed, that is, they belong to a whole mold steel. In actual use, the second template 3 is the lower die, and the first template 2 is the upper die. Multiple mounting holes are provided on the edge of the mounting plate 1, and then the mounting holes are fastened to the machine tool with bolts.

[0023] like Figure 2 As shown, a bending forming cavity 12, a shearing opening 13, a second punch 14 and a first punch 15 are sequentially provided on the top surface of the second template 3. The bending forming cavity 12, the shearing opening 13, the second punch 14 and the first punch 15 are arranged in a straight line from one end of the second template 3 to the other end.

[0024] Corresponding to the second template is, for example Figure 3 As shown, below the first template 2 are provided a first punch 10, a second punch 19, a punching cutter 20, and a bending pressure head 17, respectively corresponding to the bending forming cavity 12, the shearing opening 13, the second punch 14, and the first punch 15. Figure 1 As shown, after the second template 3 and the first template 2 are joined, as... Figure 4 and Figure 5 As shown, the first punch 10 is placed in the first punch hole 15, the second punch 19 is placed in the second punch hole 14, the punching cutter 20 is placed in the shearing opening 13, and the bottom of the bending pressure head 17 is placed in the bending forming cavity 12.

[0025] It should be noted that the shearing opening 13, the second punch 14, and the first punch 15 are all through holes, which allows the waste material produced by punching to be discharged from the holes and avoids blockage. Moreover, the first punch 15 is a round hole, the second punch 14 is a strip-shaped hole, and the shearing opening 13 is a strip-shaped opening. Of course, the shapes of the bending pressure head 17, the second punch 19, and the punching tool 20 correspond to these shapes.

[0026] Next, a stop 11 is provided on the side of the second template 3 near the bending forming cavity 12. The stop 11 is mounted on the mounting plate 1, such as... Figure 3 and Figure 4 As shown, the bottom of the bending head 17 and the cross-section of the bending forming cavity 12 are both "V" shaped structures, and the length of the bending head 17 is shorter than the length of the first punch 10, the second punch 19, and the punching cutter 20.

[0027] Based on the above embodiments, the specific stamping process is as follows: Before stamping, two rows of limiting seats 16 need to be set on the top of the second template 3. The limiting seats 16 are symmetrically distributed on both sides of the first punch 15. There are multiple limiting seats 16 in each row, and the distance between the two rows of limiting seats 16 is less than the width of the bending forming cavity 12 and the shearing opening 13. This is because when the sheet metal (such as...) Figure 4 and Figure 6 When the plate is placed between the two rows of limiting seats 16, due to the limiting effect of the limiting seats 16, the plate is directly placed in the middle of the upper part of the bending forming cavity 12, the shearing opening 13, the second punch 14, and the first punch 15. At this time, the plate is placed in the middle position of the bending forming cavity 12 and the shearing opening 13.

[0028] When the first template 2 descends, the first punch 10, the second punch 19, and the punching cutter 20 are placed in the first punch hole 15, the second punch hole 14, and the shearing opening 13, respectively. The shearing opening 13 and the punching cutter 20 work together to cut the plate, while the first punch 10 and the second punch 19 punch holes in the plate.

[0029] Control the first template 2 to rise, then advance the board forward until the end of the board abuts against the stop 11, then control the first template 2 to descend again. During this process, as... Figure 4 As shown, the first punch 10, the second punch 19, and the cutting tool 20 are respectively placed again into the first punch hole 15, the second punch hole 14, and the shearing opening 13 to punch and cut the sheet metal, as shown. Figure 5 As shown, the first template 2 continues to descend. When the bending head 17 is placed in the bending forming cavity 12, the plate near the stop 11 is directly pressed into a "V" shaped structure.

[0030] For continuous production, the sheet metal can be continuously fed towards the stop 11. The sheet metal is first punched and sheared by the first punch 10, the second punch 19, and the punching cutter 20, and then pressed into shape by the bending pressure head 17. This process is continuous, as long as the sheet metal is continuously fed towards the stop 11.

[0031] Furthermore, such as Figure 2 and Figure 3 As shown, a guide rod 5 is vertically provided on the edge of one mounting plate 1, and a guide sleeve 9 corresponding to the guide rod 5 is vertically provided on the edge of another mounting plate 1. There can be multiple guide rods 5 and guide sleeves 9, such as... Figure 1 As shown, after the first template 2 and the second template 3 are closed, the guide rod 5 is placed inside the guide sleeve 9.

[0032] Furthermore, the stop 11, the first punch 10, the second punch 19, the cutting tool 20, and the bending head 17 are all detachable because these components are consumables and need to be replaced after a certain period of use. Therefore, the roots of the stop 11, the first punch 10, the second punch 19, the cutting tool 20, and the bending head 17 are all vertically mounted on the fixed base 18, and the fixed base 18 is detachably connected to the mounting plate 1. Figure 3 and Figure 4 As shown, grooves corresponding to the fixing seats 18 are also provided on the first template 2 and the second template 3. Each fixing seat 18 is placed in the groove and the fixing seat 18 is fastened to the first template 2 and the second template 3 by bolts.

[0033] This application also proposes a cooling device, such as... Figure 1 and Figure 2 As shown, the cooling device is installed on the side of the stamping die for the civil aviation seat lock connecting plate. The specific structure of the cooling device includes a mounting base 6, with a blowing pipe 8 arranged parallel to one side of the mounting base 6. The mounting base 6 and the blowing pipe 8 are connected by a support rod 7. Multiple air nozzles 4 are provided on one side of the blowing pipe 8, and the airflow from the air nozzles 4 is directed towards the surface of the stamping die for the civil aviation seat lock connecting plate. Figure 2 and Figure 3 As shown, during installation, the mounting base 6 is fastened to the side of the mounting plate 1 with bolts. Due to the support rod 7, the height of the air blower 8 is increased, so that the air blower 8 can correspond to the surfaces of the first template 2 and the second template 3.

[0034] One end of the air blowing pipe 8 is connected to the air blowing device through a pipe. The air blowing device is a high-pressure air pump. The high-pressure air pump delivers airflow into the air blowing pipe 8 through the pipe, and then blows it onto the surface of the first template 2 and the second template 3 through the air blowing head 4. This not only dissipates heat from the surface of the first template 2 and the second template 3, but also blows away the debris on the surface of the first template 2 and the second template 3.

[0035] Based on the above embodiments, it should be further explained that after the first template 2 and the second template 3 are closed, there is still a certain distance between the two mounting plates 1, so the cooling devices installed on both sides will not come into contact with each other.

[0036] Based on the above embodiments, it should be further explained that the maximum downward stroke of the first template 2 is the stroke when it is placed inside the bending forming cavity 12, at which point the sheet material can be pressed into shape. Figure 6 The same connecting plate as shown. Figure 6 The hole indicated by the middle arrow A corresponds to the second punch 19, while the hole indicated by the arrow B corresponds to the first punch 15.

[0037] Furthermore, when the sheet metal is pressed by the bending head 17, the holes indicated by arrows A and B are located on both sides of the bending forming cavity 12, respectively. After the bending head 17 presses, the sheet metal can be formed... Figure 6 The connecting plate shown.

[0038] Based on the above embodiments, it should be further noted that the top two sides of the bending forming cavity 12 are provided with chamfers.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
