Description

Technical Field

[0001] The utility model relates to the technical field of bending equipment, in particular to a heat pipe bending device. Background Art

[0002] At present, most manual bending mechanisms use a fixed rod to pin or press one end of the pipe fitting, and then directly drive the roller to contact the pipe fitting through the rotating rod to bend the pipe fitting on the bending turntable. For example, the Chinese patent application number 202121329228.7 discloses a new type of simple square tube manual bending device, including a bending tray, an extrusion structure and a limiting clamping mechanism; the limiting clamping mechanism includes a top screw nut and a positioning angle iron, and the top screw nut and the positioning angle iron are installed at the workpiece entrance of the bending tray. The workpiece to be processed is located between the top screw nut and the positioning angle iron. The top screw nut is fixed by welding, and the positioning angle iron is fixed by bolts. The positioning top screw is installed on the top screw nut by threaded cooperation, and the positioning top screw head is designed with a rotating rod; the extrusion structure includes a sliding bracket, which moves along the bending arm II. A pushing block is installed on the sliding bracket. The sliding bracket is installed with three stacked rollers through a rotating pair, and the pushing block contacts the rollers.

[0003] For example, publication number CN220371962U discloses a manual bending mechanism comprising a base, the top of which is provided with a quick clamp, a clamping block, a pipe bending turntable, a bending block, a roller, and a rotating rod. The pipe bending turntable includes a mounting portion and a bending portion. The bottom of the pipe bending turntable mounting portion is provided at one end of the top of the base via a support block. The sidewall of the pipe bending turntable bending portion is provided with a connecting bending groove and a first fixing groove. One end of the rotating rod is provided below the pipe bending turntable via a rotating shaft. The top of the other end is provided with a roller. A bending block is provided between the roller and the pipe bending turntable. The quick clamp is provided at the other end of the top of the base. The clamping block is provided between the pipe bending turntable and the quick clamp. This utility model can not only stably fix the pipe fitting during bending without damaging the pipe fitting, but also uniformly apply pressure to the pipe fitting to bend it, effectively improving the bending efficiency and yield rate. The quick clamp and the pipe bending turntable are used to fix the pipe fitting, and then the roller and rotating rod are used to bend the pipe fitting. However, in actual application, since the installation positions of the manual clamp and the pipe bending turntable are fixed, the installation position of the bending block on the rotating rod is also fixed. Therefore, it is impossible to bend pipes of different diameters. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] See also Figure 1-4 As shown, the heat pipe bending device of the present invention is used to bend heat pipes. It includes a workbench 01, on which a fixed column 02 is fixedly mounted. A shaft mold 03 is detachably mounted on the top of the fixed column 02 via a fastener. A fixed plate 04 fixedly mounted on the workbench 01 is provided on one side of the fixed column 02. A bending plate 05 is rotatably mounted on the fixed column 02 via a bearing.

[0021] See also Figure 1As shown, a sliding guide rail 06 and a support seat 07 are fixedly mounted on the fixed plate 04, a driving source 08 is fixedly mounted on the support seat 07, a mounting plate 09 is fixedly mounted on the sliding guide rail 06, and the output end of the driving source 08 is fixedly connected to the mounting plate 09. A backing plate 10 adjacent to the shaft mold 03 is detachably mounted on the mounting plate 09 by fasteners. The backing plate 10 and the driving source 08 are located on both sides of the mounting plate 09. When in use, the heat pipe is placed between the backing plate 10 and the shaft mold 03, and the output end of the driving source 08 extends, driving the mounting plate 09 to move on the sliding guide rail 06 toward the fixed column 02, thereby fixing the heat pipe between the backing plate 10 and the shaft mold 03. The driving source 08 mounted on the fixed plate 04 is a cylinder, and other devices in the prior art can also be used to act on the mounting plate 09 to make it move along the sliding guide rail 06.

[0022] In actual use, since the shaft mold 03 and the back mold 10 are connected by fasteners, the shaft mold 03 and the back mold 10 can be removed from both the shaft mold 03 on the fixing column 02 and the back mold 10 on the mounting plate 09. At the same time, the back mold 10 can change the distance between the back mold 10 and the shaft mold 03 under the action of the driving source 08. When facing heat pipes of different diameters, they can be fixed between the back mold 10 and the shaft mold 03.

[0023] See also Figure 2 As shown, the bending plate 05 is fixedly mounted with a sliding guide rail 06 and a mounting seat 11, a driving source 08 is fixedly mounted on the mounting seat 11, and an auxiliary plate 12 is fixedly mounted on the sliding guide rail 06. The output end of the driving source 08 is fixedly connected to the auxiliary plate 12. An auxiliary die 13 adjacent to the fixed column 02 is detachably mounted on the auxiliary plate 12 via fasteners. The auxiliary die 13 is rotatably mounted on the auxiliary plate 12. The auxiliary die 13 and the driving source 08 are located on either side of the fixed plate 04.

[0024] When in use, the heat-conducting tube is fixed between the backing mold 10 and the shaft mold 03, and then the auxiliary film is driven by the driving source 08 installed on the support plate to move toward the fixed column 02, and then the auxiliary mold 13 is brought into contact with the heat-conducting tube fixed between the backing mold 10 and the shaft mold 03. A rotational force is then applied to the bending plate 05 to rotate the bending plate 05 around the fixed column 02. When the bending plate 05 rotates, the auxiliary mold 13 rotates around the fixed column 02. When the auxiliary mold 13 rotates, the heat-conducting tube rotates around the shaft mold 03 to complete the bending. The driving source 08 installed on the bending plate 05 is a cylinder, and other equipment in the prior art can also be used to act on the mounting plate 09 to move it along the sliding guide rail 06.

[0025] See also Figure 1As shown, workbench 01 is evenly distributed with several limiting holes 14, centered about the center of fixed column 02. Limiting rods 15 are positioned within these holes. These rods are placed within the corresponding limiting holes 14 according to the desired bending angle of the heat pipe. When bending plate 05 rotates and abuts against the limiting rods 15, the heat pipe's bending angle matches the desired setting.

[0026] See also Figure 3 As shown, a limit plate 16 is fixedly mounted on one side of the bending plate 05. The limit plate 16 is located directly above the limit hole 14, and a rubber plate 17 is fixedly mounted on the limit plate 16. Due to the elasticity of the rubber plate 17, the bending plate 05 can still rotate to a certain angle after the rubber plate 17 abuts the limit rod 15. The purpose of rotating the bending plate 05 to a certain angle is to shape the heat pipe after bending. Because the heat pipe will rebound after bending, the installation of the rubber plate 17 allows the bending plate 05 to rotate to a greater angle than the set bending angle of the heat pipe. This allows for springback after bending.

[0027] See also Figure 2 As shown, a gasket 18 is provided between the fixed plate 04 and the workbench 01. During assembly, the fasteners sequentially pass through the workbench 01, the gasket 18, and are connected to the fixed plate 04. When the fixed column 02 is replaced with a different type of shaft mold 03, to ensure that the backing mold 10 and the shaft mold 03 are at the same height, gaskets 18 of different heights are provided between the fixed plate 04 and the workbench 01. This ensures that the heat pipe can be fixed between the backing mold 10 and the shaft mold 03.

[0028] See also Figure 4 As shown, the shaft mold 03 includes a clamping end 19 arranged parallel to the supporting mold 10 and an arc-shaped bending section 20 arranged coaxially with the fixed column 02. The diameter of the bending section 20 is the same as the bending radius of the heat transfer tube. The bending section 20 and the clamping end 19 are both provided with a circular arc-shaped receiving groove 21 that is connected to each other. The diameter of the receiving groove 21 is adapted to the diameter of the heat transfer tube and is arranged in a "6" shape on the shaft mold 03. The supporting mold 10 and the auxiliary mold 13 are both provided with an arc-shaped clamping groove 22 with the same diameter as the receiving groove 21. The center of the clamping groove 22 and the center of the receiving groove 21 are on the same horizontal plane.

[0029] See also Figure 2 As shown, limiting grooves 23 are provided on the upper and lower sides of the shaft mold 03 and the fixed column 02, and limiting blocks 24 are provided in the limiting grooves 23. The cooperation between the limiting blocks 24 and the limiting grooves 23 prevents relative rotation between the shaft mold 03 and the fixed column 02 during the bending process.

[0030] When using the present invention, first, different models of shaft molds 03, backing molds 10, and auxiliary molds 13 are selected according to the diameter of the heat pipe to be bent, and the gaskets 18 of different thicknesses are replaced to ensure that the center of the card slot 22 and the center of the receiving groove 21 are on the same horizontal plane. The heat pipe is then placed between the shaft mold 03 and the backing mold 10. The driving source 08 on the mounting plate 09 then drives the backing mold 10 toward the shaft mold 03, securing the heat pipe between the shaft mold 03 and the backing mold 10. The driving source 08 mounted on the auxiliary plate 12 then drives the auxiliary mold 13 toward the heat pipe, causing the auxiliary mold 13 to abut against the heat pipe. Finally, an external force is used to rotate the bending plate 05, thereby bending the heat pipe.

[0031] It should be noted that for the sake of clarity, the fasteners described in this application are any one of screws, bolts, and screws. At the same time, the "drive sources" installed in different positions are marked with the same figure number "08", and the "sliding guide rails" installed in different positions are marked with the same figure number "06".

[0032] If the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
