Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a one-piece forging and pressing station mold. Background Technology

[0002] An integrated forging die is a special type of die that integrates multiple forging processes into a single die. Through a well-designed die structure, it allows the blank to undergo multiple forging operations, such as upsetting, punching, and extrusion, continuously at different stations within the same die, without the need to transfer the blank between multiple dies. Its basic structure typically includes multiple cavity areas with different functions, arranged sequentially according to the forging process. Each cavity area has precise dimensions and shape to ensure accurate deformation of the blank at each station.

[0003] Existing one-piece forging die sets suffer from drawbacks. After prolonged use, wear or damage to the die cavity makes replacement inconvenient due to the typically fixed connection of the bottom mold and the integral design of the cavity and die. This necessitates replacing the entire bottom mold, increasing production costs. Furthermore, excessively high temperatures during continuous forging can negatively impact die strength and workpiece forming quality. Therefore, we propose a one-piece forging die set.

[0012] Beneficial effects

[0013] This utility model provides a one-piece forging and forming station mold. Compared with the prior art, it has the following advantages:

[0014] 1. This one-piece forging and forming station mold, when the bottom mold needs to be replaced, the bottom mold is a detachable insert structure. The bottom mold is fixed in the mounting groove. The pin is removed from the insert rod and then from the opening and the second insertion hole. Then the fixing frame is moved, and the second insert is removed from the first insertion hole. Then the bottom mold is moved out of the mounting groove through the pull groove. Conversely, a new bottom mold is then replaced, and the bottom mold is fixed again to complete the bottom mold replacement work. At this time, the bottom mold is detachable, which reduces the production cost. At the same time, the bottom mold is installed and fixed by snap-fit, which makes the bottom mold easy to replace.

[0015] 2. This integrated forging and forming station mold features a cooling component. Inlet and outlet water valves are connected to externally circulating cooling water. As the cooling water circulates in the cooling water tank, it carries away the heat transferred by the heat-conducting copper sheets, thereby cooling the bottom mold. The upper cooling component, during forging, accelerates airflow to cool the surface of the upper mold. This cooling system effectively cools the mold, ensuring optimal forging and forming results.

[0023] 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.

[0024] like Figure 1-6As shown, a one-piece forging and forming station mold includes a base 1 and a fixing frame 7. A mounting seat 2 is fixedly connected to the top surface of the base 1. A mounting groove 3 is formed on the top surface of the mounting seat 2. A bottom mold 4 is disposed on the inner wall of the mounting groove 3. A connecting component 5 for fixing the bottom mold 4 is disposed on the surface of the bottom mold 4. A pull-out groove 6 is formed on the surface of the bottom mold 4. Fixing components 8 for fixing the bottom mold 4 are disposed on the surface of the fixing frame 7 and the surface of the mounting seat 2. Cooling components 9 for cooling the bottom mold 4 are disposed inside and on the surface of the mounting seat 2. The top surface of the base 1 is provided with... The upper mold assembly 10 is provided, with a moving hole 11 extending through its surface. An upper cooling assembly 12 is also provided on the surface of the upper mold assembly 10. Specifically, this integrated forging and forming station mold has a bottom mold 4 with cavities and openings for extruding and punching blanks. When the bottom mold 4 needs to be replaced, it is a detachable insert structure. The bottom mold 4 is fixedly installed in the mounting groove 3. The bottom mold 4 is fixedly connected in the mounting groove 3 by the connecting assembly 5 and the fixing assembly 8. At this time, only... The fixing component 8 on the fixing frame 7 needs to be operated to release the fixing of the mounting slot 3. Then, the bottom mold 4 can be taken out of the mounting slot 3 for replacement through the pull slot 6. Then, the new bottom mold 4 can be placed and fixed back into the mounting slot 3. The cooling component 9 is set up so that the mounting slot 3 can cool the mounting seat 2 through the external circulating cooling water during continuous forging. It adopts an indirect contact method. There is an isolation layer between the bottom mold 4 and the cooling medium. Heat is transferred to the cooling water through this isolation layer. The temperature of the bottom mold 4 is reduced by heat conduction. This can ensure a good cooling effect and protect the bottom mold 4 from water corrosion. The upper cooling component 12 is set up to enhance the cooling effect by accelerating the air flow and cooling the upper mold component 10. At this time, the bottom mold 4 is detachable, which reduces the production cost. At the same time, the bottom mold 4 is installed and fixed by snap-fit, which makes the bottom mold 4 easy to replace. The design of the cooling component 9 and the upper cooling component 12 can cool the mold and ensure the forming and forging effect of the mold.

[0025] like Figure 5 , Figure 6 As shown, the connecting component 5 includes a first insert 501, the first insert 501 is fixedly connected to the surface of the bottom mold 4, and a first insertion hole 502 is opened on the surface of the bottom mold 4; specifically, the connecting component 5 is configured such that the first insert 501 is inserted into the fixing component 8, and the first insertion hole 502 is used for the insertion connection of the components of the fixing component 8, which cooperates with the installation and fixing of the bottom mold 4 in the mounting groove 3.

[0026] like Figure 2 , Figure 5 , Figure 6As shown, the fixing component 8 includes an opening 801. The fixing frame 7 has openings 801 through both sides. The mounting base 2 has second insertion holes 802 through both sides, and the first insertion block 501 is movably inserted into the second insertion hole 802. The inner wall of the mounting groove 3 has a third insertion hole 803. A rod 804 is movably inserted into the inner wall of the opening 801, and a pin 805 is movably inserted into the inner wall of the rod 804. The inner wall of the fixing frame 7 is fixedly connected to a second insertion block 806, which is movably inserted into the first insertion hole 502. Specifically, when the bottom mold 4 needs to be replaced, the pin 805 is removed from the rod 804. At this time, the pin 805 can be removed from the opening 801 and the second insertion hole 802. Then, the fixing frame 7 is moved, causing the second insertion block 806 to move out of the first insertion hole 502, initially releasing the bottom mold 4 from the mounting groove 3. The bottom mold 4 is then pulled and moved through the pull slot 6, which is an "L"-shaped design. The bottom mold 4 is moved outward from the mounting slot 3, which causes the first insert block 501 to be pulled out from the third insert hole 803, thus completing the removal of the bottom mold 4. Then, a new bottom mold 4 is replaced and inserted into the mounting slot 3. Conversely, the first insert block 501 is inserted into the third insert hole 803, and the fixing frame 7 is fitted onto the surface of the mounting base 2. The second insert block 806 is inserted into the inside of the first insert hole 502. Then, the insert rod 804 is inserted into the inside of the second insert hole 802, and the pin 805 is inserted into the inner wall of the insert rod 804 to limit the insertion rod 804, thus completing the limiting connection of the fixing frame 7 and fixing the bottom mold 4. This completes the replacement of the bottom mold 4. At this time, the bottom mold 4 is fixedly connected by a snap-fit ​​method, which makes the bottom mold 4 easy to disassemble and assemble.

[0027] like Figure 2 , Figure 4 As shown, the cooling assembly 9 includes a heat-conducting copper sheet 901. The mounting base 2 is equipped with the heat-conducting copper sheet 901 and a cooling water tank 902. The surface of the mounting base 2 is equipped with inlet and outlet water valves 903. Specifically, with the cooling assembly 9, after the bottom mold 4 is installed, the surface of the bottom mold 4 is in close contact with the surface of the heat-conducting copper sheet 901. The heat-conducting copper sheet 901 can conduct heat. The inlet and outlet water valves 903 are connected to circulating cooling water. When the cooling water circulates in the cooling water tank 902, it can carry away the heat transferred by the heat-conducting copper sheet 901, thereby cooling the bottom mold 4 and preventing the bottom mold 4 from overheating.

[0028] like Figure 1 , Figure 2As shown, the upper mold assembly 10 includes a lifting slide rod 1001. The lifting slide rod 1001 is fixedly connected to the top surface of the base 1. A limiting sleeve 1002 is movably sleeved on the surface of the lifting slide rod 1001. A top plate 1003 is fixedly sleeved on the surface of the limiting sleeve 1002, and the top plate 1003 is connected to a hydraulic device. A moving hole 11 is opened through the surface of the top plate 1003. An upper mold 1004 is fixedly connected to the bottom surface of the top plate 1003, and a moving hole 11 is opened through the surface of the top plate 1003. A spring buffer rod 1005 is fixedly connected to the top surface of the mounting base 2. Specifically, in the configuration of the upper mold assembly 10, the lifting slide rod 1001 is used to connect the top plate 1003, the upper mold 1004 is used for forging the blank, and the limiting sleeve 1002 and the spring buffer rod 1005 are used to limit the movement of the mold. During the movement of the top plate 1003, the spring buffer rod 1005 can pass through the moving hole 11.

[0029] like Figure 2 , Figure 3 As shown, the upper cooling component 12 includes a fixing block 1201. The fixing block 1201 is fixedly connected to the bottom surface of the top plate 1003, and a blower 1202 is fixedly connected to the surface of the fixing block 1201. An air outlet frame 1203 is provided at the air outlet end of the blower 1202 through a pipe, and the air outlet frame 1203 is fixedly connected to the fixing block 1201. Specifically, the upper cooling component 12 is connected to the top plate 1003. During forging, the blower 1202 runs, and the air force generated by the blower 1202 blows outward through the air outlet frame 1203, accelerating the air flow speed at the upper mold 1004 and cooling the surface of the upper mold 1004 so that the upper mold 1004 will not have an excessively high temperature.

[0030] Working principle: When the bottom mold 4 needs to be replaced in this one-piece forging and forming station mold, the bottom mold 4 is a detachable insert structure. The bottom mold 4 is fixed in the mounting groove 3. When the pin 805 is removed from the insert rod 804, the pin 805 can be removed from the opening 801 and the second insertion hole 802. Then, the fixing frame 7 is moved, so that the second insert 806 is removed from the first insertion hole 502, initially releasing the limiting fixation of the bottom mold 4 in the mounting groove 3. Then, the bottom mold 4 is pulled and moved by the pull groove 6. The pull groove 6 is an "L" shaped design. The bottom mold 4 is moved outward from the mounting groove 3, which drives the first insert 501 to be pulled out from the third insertion hole 803, completing the removal of the bottom mold 4. Then, a new bottom mold 4 is replaced and inserted into the mounting groove 3. Conversely, the first insert 501 is inserted into the third insertion hole 803, and the fixing frame 7 is moved. The second insert 806 is inserted into the first insertion hole 502 and then inserted into the second insertion hole 802. The pin 805 is inserted into the inner wall of the insert 804 to limit the insertion 804, thus completing the limiting connection of the fixing frame 7 and fixing the bottom mold 4. The bottom mold 4 is then replaced. The cooling component 9 is set up so that the heat-conducting copper sheet 901 can conduct heat. The inlet and outlet water valves 903 are connected to the circulating cooling water. When the cooling water circulates in the cooling water tank 902, it can carry the heat transferred by the heat-conducting copper sheet 901 outward, thereby cooling the bottom mold 4. The upper cooling component 12 is set up so that during forging, the air force generated by the blower 1202 is blown outward through the air outlet frame 1203, which accelerates the air flow speed at the upper mold 1004 and cools the surface of the upper mold 1004.
