Description

Technical Field

[0001] This utility model relates to the field of engine technology, and in particular to a device for turning holes in the side wall of a cylinder. Background Technology

[0002] The outer flame tube of a certain type of engine is made of high-temperature alloy and is a cylindrical annular part with one (or several) annular perforations distributed on the tube wall. Existing technology uses a single-hole forming method, where the bottom of the mold is mounted on a support, and after completing one perforation, the mold is rotated at a certain angle before the next perforation is made. This method results in high labor intensity and low efficiency.

[0003] Therefore, how to improve the efficiency of hole-making is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0012] Optionally, in the above-mentioned cylindrical sidewall turning device, the inner wall of the mounting hole and the outer wall of the die insert are respectively provided with mutually cooperating positioning bosses. When the limiting plate pushes the die insert to move in the mounting hole, the positioning bosses are used to limit and fix the die insert.

[0013] Optionally, in the above-mentioned cylindrical sidewall turning device, the cylindrical sidewall turning device further includes a second elastic element. The die insert is connected to the die insert mounting base through the second elastic element. After the limiting plate releases the die insert from its restriction, the die insert moves away from the mounting hole through the second elastic element, so that the punch is disengaged from the punch.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The core of this utility model is to provide a cylindrical sidewall turning device for turning holes on the outer flame tube wall, thereby improving the efficiency of turning holes.

[0038] like Figure 1 As shown in the figure, this utility model discloses a cylindrical sidewall flanging device, including a base 100, a die insert 200, and a wedge portion 300. The die insert 200 is connected to the base 100 and has a punch for flanging the outer flame tube wall. During flanging, the die insert 200 is located inside the outer flame tube. The wedge portion 300, located on the outer side of the outer flame tube, includes an upper wedge 310 and a lower wedge 320. The lower wedge 320 is slidably mounted on the base 100 and has a punch 321 that mates with the punch in the die insert 200. Simultaneously, the contact ends of the upper wedge 310 and the lower wedge 320 have mating wedge surfaces. When the upper wedge 310 is pressed down, the mating wedge surfaces push the lower wedge 320 to move, causing the punch 321 of the lower wedge 320 to move towards the die insert 200. The punch moves, and the punch 321 extends into the punch hole to punch out a hole in the outer flame tube wall. Moreover, the cylindrical side wall turning device provided in this embodiment has multiple wedges 300 and die inserts 200. One die insert 200 corresponds to one wedge 300. Each wedge 300 and die insert 200 is distributed at intervals along the circumference of the outer flame tube. Thus, the cylindrical side wall turning device provided in this embodiment can simultaneously punch out multiple holes around the outer flame tube wall, improving the turning hole production efficiency.

[0039] Meanwhile, the wedge portion 300 also includes a first elastic element. The lower wedge 320 is connected to the base 100 through the first elastic element. The upper wedge 310 presses down to push the lower wedge 320 to slide, and through the punch 321 and the punch hole, it flips the hole. After the flipping is completed, the upper wedge 310 and the lower wedge 320 separate. At this time, the lower wedge 320 returns to its original position through the first elastic element with elastic potential energy, so as to facilitate the next flipping. In a specific embodiment, the first elastic element is a compression spring. Before the lower wedge 320 slides to flip the hole, the compression spring is in its initial state. After the upper wedge 310 pushes the lower wedge 320 to flip the hole, the compression spring undergoes elastic deformation, so that after the upper wedge 310 and the lower wedge 320 separate, the elastically deformed compression spring returns to its original position.

[0040] like Figure 1As shown, the cylindrical sidewall turning device provided in this embodiment also includes a die insert mounting base 210 and a limiting plate 400. The die insert mounting base 210 is fixed on the base 100 and has a mounting hole. The die insert 200 is slidably inserted into the mounting hole of the die insert mounting base 210. The limiting plate 400 is arranged at the end away from the die insert 200 with the punch hole. Thus, the limiting plate 400 pushes the die insert 200 into the mounting hole of the die insert mounting base 210. During the process of the punch 321 of the lower wedge 320 extending into the punch hole of the die insert 200, the limiting plate 400 limits the movement of the die insert 200 and prevents the die insert 200 from exiting from the mounting hole of the die insert mounting base 210, thus ensuring the smooth turning of the outer flame tube wall.

[0041] In addition, the inner wall of the mounting hole of the die insert mounting base 210 and the outer wall of the die insert 200 are respectively provided with mutually cooperating positioning bosses. During the sliding process of the die insert 200 in the mounting hole of the die insert mounting base 210, the inner wall of the mounting hole cooperates with the positioning boss of the die insert 200 to prevent the die insert 200 from sliding out of the mounting hole. At the same time, the cooperation between the positioning plate 400 and the positioning boss positions and fixes the die insert 200, so that the die insert 200 has good stability in the mounting hole of the die insert mounting base 210 during the entire hole turning process, so as to ensure the smooth cooperation between the punch and the punch 321 for hole turning.

[0042] In a specific embodiment, the cylindrical sidewall turning device provided in this embodiment is further provided with a second elastic element. The die insert 200 is installed on the die insert mounting base 210 through the second elastic element. The second elastic element can also be a compression spring. During the process of the limiting plate 400 pushing the die insert 200 to move in the mounting hole of the die insert mounting base 210 towards the punch 321, the compression spring is compressed and generates elastic deformation. After the turning is completed, the limiting plate 400 is separated from the die insert 200. After contacting the limitation of the die insert 200, the compression spring with elastic potential energy is reset, so that the die insert 200 moves away from the lower wedge 320 through the compression spring, i.e. the second elastic element, so that the punch of the die insert 200 is separated from the punch 321 of the lower wedge 320, so as to facilitate the quick disassembly of the outer flame tube, further reducing the workload and improving the work efficiency.

[0043] like Figure 1As shown, the end of the die insert 200 that contacts the limiting plate 400 is provided with an arc-shaped guide surface. When the limiting plate 400 presses down to push the die insert 200, the end of the limiting plate 400 abuts against the guide surface of the die insert 200. As the limiting plate 400 continues to push, the limiting plate 400 slides along the guide surface, thereby realizing the sliding of the die insert 200 in the mounting hole of the die insert mounting base 210 by the limiting plate 400 through the guide surface.

[0044] like Figure 1 As shown, the cylindrical sidewall flanging device provided in this embodiment also includes an upper pressure plate 500 and a fixed plate 600. One side of the fixed plate 600 is connected to the upper pressure plate 500, while the limiting plate 400 and the upper inclined wedge 310 are installed on the side of the fixed plate 600 facing away from the upper pressure plate 500, so that the limiting plate 400 and the upper inclined wedge 310 are connected to the upper pressure plate 500 through the fixed plate 600. Therefore, by pressing the upper pressure plate 500, each limiting plate 400 and each upper inclined wedge 310 moves downward at the same time. The limiting plate 400 and the upper inclined wedge 310 push the die insert 200 and the lower inclined wedge 320 closer to each other, so that the punch 321 presses the cylinder wall and extends into the punch hole to extrude and create a flanging hole. This ensures the synchronous movement of the die insert 200 and the lower inclined wedge 320, and realizes the simultaneous preparation of each flanging hole around the outer flame cylinder wall.

[0045] Furthermore, the cylindrical sidewall turning device provided in this embodiment is also provided with guide posts 700. Multiple guide posts 700 are provided, and each guide post 700 is distributed at intervals on the same circumference with the center of the placed outer flame tube as the center. The guide posts 700 are installed and fixed on the base 100. The upper pressure plate 500 has guide holes, and one guide hole cooperates with one guide post 700, so that the upper pressure plate 500 can be slidably sleeved on the guide post 700 through the guide hole. During the process of pushing the upper pressure plate 500, each guide post 700 plays a guiding role, which improves the smoothness of the movement of the upper pressure plate 500, improves the uniformity of the force applied by the upper pressure plate 500 to each limiting plate 400 and each upper inclined wedge 310, and improves the synchronization of movement.

[0046] In another specific embodiment, the cylindrical sidewall perforation device provided in this embodiment is further provided with a pressure plate 800 and a third elastic element. The pressure plate 800 is installed on the fixed plate 600 through the third elastic element. During the process of pushing the upper pressure plate 500 to move, the pressure plate 800 abuts against the outer flame tube and applies a pressing force to the outer flame tube. When the cylinder wall is squeezed and perforated, the outer flame tube is ensured to have good stability. The third elastic element located between the pressure plate 800 and the fixed plate 600 plays a buffering role to prevent the pressure plate 800 from applying too much pressure to the outer flame tube and causing damage to the outer flame tube. The third elastic element can also be a compression spring.

[0047] like Figure 1 and Figure 2 As shown, the base 100 is also provided with a lower fixing plate 110. The lower fixing plate 110 has a sliding groove 120, in which the lower wedge 320 is slidably installed. The sliding groove 120 extends along the moving direction of the lower wedge to ensure that the lower wedge 320 moves toward the die insert 200. The punch 321 of the lower wedge 320 is pressed into the punch hole of the die insert 200, thereby realizing the slidable installation of the lower wedge 320 on the base 100 through the sliding groove 120 starting from the lower fixing plate 110. Meanwhile, the base 100 is also provided with a limiting post 130. After the hole is turned over, the pressure plate 800 and the limiting plate 400 installed on the pressure plate 800 are removed from the cylindrical sidewall hole turning device provided in this embodiment. After the outer flame tube that has been turned over is pulled out, the die insert 200, which is pushed by the second elastic element, moves until it abuts against the limiting post 130. This prevents the die insert 200 from completely detaching from the mounting hole of the die insert mounting seat 210, ensuring that part of the die insert 200 is still in the mounting hole of the die insert mounting seat 210. This allows the limiting plate 400 to quickly push the die insert 200 to move in the mounting hole during the next extrusion hole turning, ensuring that the die insert 200 and the mounting hole of the die insert mounting seat 210 are smoothly matched.

[0048] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0049] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
