Description

Technical Field

[0001] The utility model relates to a core-penetrating device, in particular to a core-penetrating device for bending window frame profiles. Background Art

[0002] The rail transit industry processes a wide range of profile cross-sections, with a wide variety of cross-sections used in vehicle body parts. This presents a significant challenge for bending aluminum window frames. Existing window frame bending methods often suffer from issues such as collapse or pitting at the bend, as well as excessive twisting, which impacts production efficiency and precision. Utility Model Content

[0003] The technical problem to be solved by the utility model is that in the prior art, when a window frame is bent, collapse or pits are easily formed at the bent portion.

[0004] In order to solve the above technical problems, the present invention provides a technical solution:

[0005] The lockhole that is formed on the upper side of the second end face of the second nut is formed on the second nut, and the lockhole that is formed on the second nut is formed on the third nut.

[0006] Furthermore, there are at least two steering heads, and the first hanging ear on one of the steering heads is placed into the connecting cavity on the other steering head. The other positioning pin is used to pass through the second connecting hole, the first connecting hole and the third connecting hole which are symmetrical up and down in sequence, so as to connect the two steering heads. Different numbers of steering heads can be selected according to the different bending angles required to adapt to the arc lengths corresponding to different angles.

[0007] For example, when the bending angle is 90°, the length of the entire adapter after connection is no more than half the length of the arc to be bent.

[0008] Furthermore, the second hanging ear and the third hanging ear are symmetrically arranged in the upper and lower parts, the second connecting hole and the third connecting hole are symmetrically arranged in the upper and lower parts, and the first hanging ear, the second hanging ear and the third hanging ear are all integrally connected to the connecting block.

[0009] Furthermore, the ends of the first hanging ear, the second hanging ear and the third hanging ear away from the connecting block are all arc-shaped structures, and the ends on the two side walls of the U-shaped frame corresponding to the adapter are also arc-shaped structures. The first hanging ear can rotate freely around the corresponding positioning pin between the two side walls of the U-shaped frame and in the connecting cavity, making it convenient for the steering head to turn with the bend without any jamming.

[0010] Furthermore, the guide sleeve, inner cavity core and positioning pin are all made of carbon steel and placed in the cavity of the profile, which can provide support and prevent the profile surface from sinking.

[0011] Furthermore, before placing the guide sleeve and the steering head into the cavity on the window frame to be bent, lubricating oil is applied to the inner cavity core and the positioning pin to facilitate the steering head to turn.

[0012] The beneficial effects of the utility model are:

[0013] In the utility model, the guide sleeve and the adapter, as well as the adapters and the adapters themselves, can rotate freely around their respective corresponding positioning pins. When placed in the cavity on the window frame profile, they will rotate accordingly with the bending angle, which not only plays a supporting role but also does not damage the profile. Furthermore, the guide sleeve, inner cavity core and positioning pins are all made of carbon steel, which is sturdy and durable. They are placed in the profile cavity for support, avoiding the problem of collapse or pits when the window frame profile is bent.

[0023] The names of the messages or information exchanged between multiple devices in the embodiments of the present invention are only used for illustrative purposes and are not used to limit the scope of these messages or information. Example

[0024] A window frame profile bending and core-threading device comprises a guide sleeve 1, a steering head 14 is connected to the guide sleeve 1, and the steering head 14 comprises an inner cavity core and a positioning pin 2.

[0025] The inner cavity core includes a connecting block 3, and a first hanging ear 5 with a first connecting hole 4 is provided in the middle position of the left end face of the connecting block 3. The first hanging ear 5 and the connecting block 3 are integrally connected. A second hanging ear 7 with a second connecting hole 6 is provided on the upper side of the right end face of the connecting block 3, and a third hanging ear 9 with a third connecting hole 8 is provided on the lower side. The second hanging ear 7 and the third hanging ear 9 are symmetrically arranged up and down, and the second connecting hole 6 and the third connecting hole 8 are symmetrically arranged up and down. The second hanging ear 7 and the third hanging ear 9 are integrally connected to the connecting block 3.

[0026] The space between the second hanging ear 7 and the third hanging ear 9 is a connecting cavity 10, the size of the connecting cavity 10 matches the size of the first hanging ear 5, and the ends of the first hanging ear 5, the second hanging ear 7 and the third hanging ear 9 away from the connecting block 3 are all arc-shaped structures.

[0027] A connecting threaded hole 11 is provided at the center point of one end of the guide sleeve 1, and a U-shaped frame 12 is provided at the other end. Symmetrical fourth connecting holes 13 are provided on both side walls of the U-shaped frame 12. The size between the two side walls of the U-shaped frame 12 matches the size of the first hanging ear 5, and the ends of the two side walls of the U-shaped frame 12 corresponding to the adapter are also arc-shaped structures.

[0028] In this embodiment, three steering heads 14 are provided, the bending angle of the window frame is 90°, and the positioning pin 2 is a stepped shaft to prevent the positioning pin 2 from falling off after installation.

[0029] During assembly, the three steering heads 14 are first assembled together. Specifically, the first hanging ear 5 on the second steering head 14 is first placed into the connecting cavity 10 on the first steering head 14, and the corresponding positioning pin 2 is used to sequentially penetrate the second connecting hole 6, the first connecting hole 4 and the third connecting hole 8 that are symmetrical up and down, thereby connecting the first and second steering heads 14. Then, the first hanging ear 5 on the third steering head 14 is placed into the connecting cavity 10 on the second steering head 14, and the corresponding positioning pin 2 is used to sequentially penetrate the second connecting hole 6, the first connecting hole 4 and the third connecting hole 8 that are symmetrical up and down, thereby connecting the second and third steering heads 14. The overall length of the three steering heads 14 is slightly less than half of the arc of the angle to be bent.

[0030] When in use, the guide sleeve 1 is installed on the horizontal guide rod of the existing pipe bending machine through the connecting threaded hole 11 using a thread, and then the first hanging ear 5 of the first steering head 14 is set between the two side walls of the U-shaped frame 12, and the corresponding positioning pin 2 is used to pass through the fourth connecting hole 13 and the first connecting hole 4 to connect the guide sleeve 1 and the adapter together. The first hanging ear 5 can rotate freely around the corresponding positioning pin 2 between the two side walls of the U-shaped frame 12 and in the connecting cavity 10, making it convenient for the steering head 14 to turn as the bending is performed without getting stuck.

[0031] The cross-sectional dimensions of the guide sleeve 1 match the cavity dimensions of the window frame to avoid the guide sleeve 1 remaining in the cavity after bending. The cross-sectional dimensions of the inner cavity core match the cavity dimensions of the window frame to avoid getting stuck in the inner cavity of the profile after a 90° bend. The guide sleeve 1, inner cavity core and positioning pin 2 are all made of carbon steel and placed in the cavity of the profile to provide support and avoid depression of the profile surface.

[0032] After the core-penetrating device is installed, first apply lubricating oil on the inner cavity core and the positioning pin 2, then pass the core-penetrating device through the cavity of the window frame profile 15 that needs to be bent, and use a bending machine to bend the window frame. The inner cavity core and the positioning pin 2 are bent 90° along the curvature of the window frame profile 15. The guide sleeve 1 and the adapter, as well as the adapters and the adapters, can rotate freely around their corresponding positioning pins 2. When placed in the cavity on the window frame profile 15, it will rotate accordingly with the bending angle, which not only plays a supporting role, but also will not damage the profile, thereby avoiding the problem of collapse or pits in the window frame profile 15 when bending.
