Description

Technical Field

[0001] This utility model relates to the field of titanium alloy flange forging technology, and in particular to a forming die for titanium alloy flange forging. Background Technology

[0002] Flanges, also known as flange discs or flanges, are commonly used connecting components in mechanical engineering. They are used to connect equipment such as pipes, valves, pumps, and containers, enabling them to achieve a sealed connection and force transmission. Titanium alloy flange forging dies have cavities that are precisely matched to the flange parts, ensuring that the titanium alloy is formed according to design requirements during the forging process, thereby obtaining flange products with high dimensional accuracy and accurate shape.

[0003] A search revealed that the document with announcement number "CN221909643U" mentions "This utility model discloses a precision forging mold for oil pipeline flanges, including a base plate with a mold groove inside. A cover plate is rotatably connected to one side of the base plate, and a spraying assembly is provided on one side of the cover plate. The spraying assembly includes an annular block, an annular groove, a sliding block, a connecting rod, a connecting plate, a cylinder, a circular hole, an air pump, an anti-corrosion coating box, and a drive motor. The annular block is fixedly installed on the cover plate, and an annular groove is provided on one side of the annular block. The two ends of the connecting rod are respectively fixedly installed on the sliding block and the cylinder. Through the spraying assembly, the cylinder on one side of the cover plate is inserted into the mold groove. The drive motor is started, which drives the sliding block on the other end of the connecting plate to rotate along the annular groove, causing the cylinder on one end of the connecting rod to rotate accordingly." The device uses an air pump to spray anti-corrosion coating onto the mold groove through a pipe into a cylindrical cavity, improving the mold's corrosion resistance and extending its service life. The spraying assembly allows a cylinder on one side of the cover plate to be inserted into the mold groove. Activating the drive motor rotates a sliding block on the other end of the connecting plate along an annular groove, causing the cylinder on one end of the connecting rod to rotate as well. The air pump then pumps the anti-corrosion coating through a pipe into the cylinder, spraying it onto the mold groove through a circular hole, thus improving the mold's corrosion resistance and extending its service life. However, this device lacks a mold heat dissipation structure. The titanium alloy flange forging temperature is high, and the lack of sufficient heat dissipation will cause the mold temperature to rise rapidly and be difficult to lower, leading to thermal fatigue cracks and shortening the mold's service life.

[0004] To address these issues, we provide a forming die for forging titanium alloy flanges. Utility Model Content

[0005] The purpose of this invention is to provide a forming die for forging titanium alloy flanges, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forming mold for forging titanium alloy flanges, comprising a lower mold shell and a heat dissipation assembly, wherein a heat dissipation assembly is installed on one side of the lower mold shell, the heat dissipation assembly includes a heat-conducting inner cavity opened inside the lower mold shell, a guide pipe is installed at one end of the heat-conducting inner cavity, and a pump is installed at the other end of the guide pipe.

[0007] Preferably, a liquid storage tank is installed at the bottom of the pump, a cooling plate is installed on one side of the liquid storage tank, a return pipe is installed on one side of the liquid storage tank, and the return pipe is fixedly connected to the other end of the heat-conducting inner cavity.

[0008] Preferably, electric telescopic rods are installed on both sides of the lower mold shell, and a movable plate is fixedly connected to the telescopic end of the electric telescopic rod.

[0010] Preferably, an upper pressure mold is fixedly connected to the bottom end of the upper pressure plate, an annular heat sink is fixedly connected to the inner side of the upper pressure mold, and a fan is installed on the surface of the upper pressure plate.

[0011] Preferably, support rods are fixedly connected to the four corners of the bottom end of the lower mold shell, and springs are provided at the bottom of the support rods, with damping blocks provided at the bottom of the springs.

[0012] Preferably, a sleeve rod is slidably connected to the outer side of the support rod via a slot, and a support foot is fixedly connected to the bottom end of the sleeve rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A heat-conducting cavity directly inside the lower mold shell is provided by a heat dissipation component, allowing a large amount of coolant to circulate rapidly, completing high-temperature heat dissipation and preventing the mold from experiencing increased thermal fatigue, which could lead to mold damage and affect the precision of the machined parts. The pump forces the coolant in the storage tank into the heat-conducting cavity through the guide pipe. After the coolant quickly absorbs a large amount of heat, it returns to the storage tank through the return pipe to complete the circulation. The cooling plate cools the coolant to ensure its heat absorption effect. The upper pressure plate moves downward along the guide rod to abut the upper mold and the lower mold shell, causing the internal material to be compressed and formed. The heat at the top is quickly absorbed by the annular heat dissipation plate and dissipated rapidly by the fan accelerating airflow. The electric telescopic rod extends and retracts, causing the moving plate to move upward, so that the ejector rod pushes out the machined parts to complete the demolding.

[0015] 2. During the machining process, the support rod, spring, damping block, and sleeve rod form a shock absorption structure to reduce the impact of vibration during the machining process. Attached Figure Description

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

[0022] Please see Figure 1-4 As shown, a forming die for forging a titanium alloy flange includes a lower die shell 1 and a heat dissipation assembly 2. The heat dissipation assembly 2 is installed on one side of the lower die shell 1. The heat dissipation assembly 2 includes a heat-conducting inner cavity 201 opened inside the lower die shell 1. A guide pipe 202 is installed at one end of the heat-conducting inner cavity 201, and a pump 203 is installed at the other end of the guide pipe 202.

[0023] Furthermore, a liquid storage tank 204 is installed at the bottom of the pump 203. A cooling chip 205 is installed on one side of the liquid storage tank 204, and a return pipe 206 is installed on one side of the liquid storage tank 204. The return pipe 206 is fixedly connected to the other end of the heat-conducting inner cavity 201. The pump 203 pressurizes the coolant in the liquid storage tank 204 into the heat-conducting inner cavity 201 through the guide pipe 202. After the coolant quickly absorbs a large amount of heat, it enters the liquid storage tank 204 through the return pipe 206 to complete the circulation. The cooling chip 205 cools the coolant to ensure its heat absorption effect.

[0024] Furthermore, electric telescopic rods 207 are installed on both sides of the lower mold shell 1. A movable plate 208 is fixedly connected to the telescopic end of the electric telescopic rod 207. A push rod 209 is fixedly connected to the upper surface of the movable plate 208. The push rod 209 and the lower mold shell 1 form a sliding structure through a slot. The extension and retraction of the electric telescopic rod 207 drives the movable plate 208 to move upward, so that the push rod 209 pushes out the workpiece to complete the demolding.

[0025] Furthermore, a guide rod 210 is fixedly connected to the top of the lower mold shell 1, and an upper pressure plate 211 is slidably connected to the outer side of the guide rod 210 through a slot. The upper pressure plate 211 moves along the guide rod 210 to prevent displacement.

[0026] Furthermore, an upper pressure mold 212 is fixedly connected to the bottom end of the upper pressure plate 211, and an annular heat sink 213 is fixedly connected to the inner side of the upper pressure mold 212. A fan 214 is installed on the surface of the upper pressure plate 211. The upper pressure mold 212 abuts against the lower mold shell 1, so that the internal material is pressed and formed. The heat at the top is quickly absorbed by the annular heat sink 213 and dissipated quickly by accelerating airflow through the fan 214.

[0027] Furthermore, support rods 3 are fixedly connected to the four corners of the bottom end of the lower mold shell 1. Springs 4 are installed at the bottom of the support rods 3, and damping blocks 5 are installed at the bottom of the springs 4. During the processing of the workpiece, the support rods 3, springs 4, damping blocks 5, and sleeve rods 6 form a shock absorption structure to reduce the impact of vibration during the processing.

[0028] Furthermore, a sleeve rod 6 is slidably connected to the outside of the support rod 3 via a slot, and a support foot 7 is fixedly connected to the bottom end of the sleeve rod 6, which expands the support area to maintain stability.

[0029] Working principle: In use, firstly, the material is introduced into the central cavity of the lower mold shell 1. The upper pressure plate 211 moves downward along the guide rod 210 to abut the upper pressure mold 212 against the lower mold shell 1, so that the internal material is compressed and formed. Secondly, the pump 203 presses the coolant in the storage tank 204 into the heat-conducting inner cavity 201 through the guide pipe 202. After the coolant quickly absorbs a large amount of heat, it enters the storage tank 204 through the return pipe 206 to complete the circulation. The cooling plate 205 cools the coolant to ensure its heat absorption effect. The heat at the top is quickly absorbed by the annular heat dissipation plate 213 and the air flow is accelerated by the fan 214 to dissipate heat quickly. Thirdly, the electric telescopic rod 207 extends and retracts, driving the moving plate 208 to move upward, so that the ejector rod 209 ejects the workpiece to complete the demolding. Fourthly, during the processing of the workpiece, the support rod 3, spring 4, damping block 5, and sleeve rod 6 form a shock absorption structure to reduce the impact of vibration during the processing. In this way, the use of a forming mold for forging titanium alloy flanges is completed.
