Description

Technical Field

[0001] The utility model relates to the technical field of automobile stamping parts, in particular to an automobile stamping die cooling device. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into components (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired component. The materials used to make stamping dies include steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloy, low-melting-point alloy, aluminum bronze, polymer materials, etc. Most of the materials used to make stamping dies are steel-based. Commonly used materials for working parts of dies include: carbon tool steel, low-alloy tool steel, high-carbon high-chromium or medium-chromium tool steel, medium-carbon alloy steel, high-speed steel, matrix steel, cemented carbide, steel-bonded cemented carbide, etc.

[0003] In the patent with publication number CN213104132U, a cooling device for automobile stamping mold is disclosed, including an upper mold and a lower mold, wherein the upper mold and the lower mold are both provided with cooling pipes with annular passages, wherein one end of the cooling pipe is an inlet, and the other end of the cooling pipe is an outlet, wherein the inlet is connected to a water inlet pipe, and the water inlet pipes are commonly connected to a chiller, wherein an inlet pump is provided at one end of the water inlet pipe close to the chiller, wherein the outlet is connected to a water outlet pipe, and the water outlet pipes are commonly connected to a water tank, wherein a pumping pipe is connected to the bottom of the chiller, and the pumping pipe passes through the top of the water tank and extends to the bottom of the water tank. Beneficial effect: The fan blows air into the air duct, and the wind passes through the air cavity and the ventilation duct in turn, and finally is discharged into the heat dissipation pipe, so that the heat collected inside the heat dissipation pipe is blown away by the wind, and finally the heat is quickly discharged to the outside from the two ports of the heat dissipation pipe, thereby further accelerating the heat dissipation efficiency.

[0023] Embodiment 1

[0024] An automobile stamping die cooling device, as Figure 1-Figure 5 shown, includes a support frame 1, a pressing block 11, a die 12, an air cooling mechanism and a water cooling mechanism. The pressing block 11 is slidably connected to the front side of the support frame 1. The die 12 is fixedly connected to the middle of the front side of the support frame 1. An air cooling mechanism is provided on the support frame 1, and a water cooling mechanism is provided on the support frame 1.

[0025] As Figure 3 and Figure 4 shown, the air cooling mechanism includes a wind guiding plate 2, a blower 21, a pushing frame 22, an inclined rod 23, a connecting rod 24, a compression spring 25, a pushing block 26, a connecting pipe 27 and a first air pipe 28. The wind guiding plate 2 distributed longitudinally up and down is fixedly connected to the front side of the support frame 1. The blower 21 is fixedly connected to the left part of the rear side of the support frame 1. The pushing frame 22 is slidably connected to the left side of the support frame 1. A compression spring 25 is fixedly connected between the pushing frame 22 and the support frame 1. The inclined rod 23 is fixedly connected to the left side of the pressing block 11. The inclined rod 23 contacts and cooperates with the pushing frame 22. The connecting rod 24 is slidably connected inside the support frame 1. The connecting pipe 27 is fixedly connected to the left part of the rear side of the support frame 1. The pushing block 26 is slidably connected inside the connecting pipe 27. One end of the connecting rod 24 is fixedly connected to the pushing frame 22, and the other end of the connecting rod 24 is fixedly connected to the pushing block 26. The first air pipe 28 is in a towel shape. One end of the first air pipe 28 is communicated with the blower 21, and the other three ends of the first air pipe 28 respectively pass through different positions of the connecting pipe 27 and are respectively communicated with the longitudinally distributed wind guiding plate 2.

[0026] As Figure 5 shown, the water cooling mechanism includes a cold water pipe 3, a water tank 31, a threaded rod 32, a guiding block 33, a valve bolt 34 and a water valve 35. The water tank 31 is fixedly connected to the top of the support frame 1. The cold water pipe 3 is fixedly connected inside the support frame 1. The cold water pipe 3 is fixedly connected to the die 12. One end of the cold water pipe 3 is communicated with the water tank 31, and the other end of the cold water pipe 3 is communicated with the external air. The water valve 35 is fixedly connected to the outside of the cold water pipe 3. The threaded rod 32 is rotatably connected to the right side of the support frame 1. The guiding block 33 is fixedly connected to the right side of the pressing block 11. The guiding block 33 is threadedly connected to the threaded rod 32. The valve bolt 34 is fixedly connected to the top end of the threaded rod 32. The valve bolt 34 is rotatably connected to the water valve 35.

[0027] As Figure 6 shown, it further includes an exhaust air plate 4, an air cylinder 41 and a second air pipe 42. The exhaust air plate 4 is fixedly connected to the lower part of the front side of the support frame 1. The air cylinder 41 is fixedly connected to the right side of the top of the support frame 1. The piston rod of the air cylinder 41 is above the pressing block 11. The second air pipe 42 is fixedly connected to the rear side of the support frame 1. One end of the second air pipe 42 is communicated with the exhaust air plate 4, and the other end of the second air pipe 42 is communicated with the air cylinder 41.

[0028] As Figure 3As shown, the side where the push frame 22 contacts the inclined rod 23 is an inclined surface.

[0029] like Figure 6 As shown, the air outlet of the exhaust plate 4 is oriented obliquely downward to clean impurities on the support frame 1 and the mold 12 .

[0030] After the pressing block 11 and the mold 12 cooperate and stamp the heated sheet into shape, the pressing block 11 and the mold 12 need to be cooled down to avoid overheating damage. At this time, the worker can start the blower 21, and the gas passes through the first air pipe 28 to the upper, middle and lower air guide plates 2. At this time, the three air guide plates 2 blow air at the same time to cool the pressing block 11. Then the worker moves the pressing block 11, the inclined rod 23 and the guide block 33 upward and takes out the product. The upward movement of the guide block 33 will drive the threaded rod 32 and the valve bolt 34 to rotate, and the water valve 35 will be slowly opened. The water in the water tank 31 gradually flows into the cold water pipe 3 and presses the mold 12. When the water cooling is performed and the guide block 33 continues to move upward, the valve is opened to a greater extent, the water output of the cold water pipe 3 is also greater, and the cooling effect is also better, so that the mold 12 can be cooled in a short time while preventing the mold 12 from being deformed and cracked due to the too rapid alternation of hot and cold. Similarly, when the inclined rod 23 moves upward to contact the bottom of the push frame 22, it squeezes the push frame 22 and moves the push frame 22, the connecting rod 24 and the push block 26 backward, and the compression spring 25 is immediately compressed. At this time, the push block 26 blocks the first air pipe 28 that is used to inject air to the lower air guide plate 2, and the gas only flows from the upper and middle air guide plates 2 When the inclined rod 23 continues to move upward to contact the top of the push frame 22, it will squeeze the push frame 22 and make the push frame 22, the connecting rod 24 and the push block 26 move further backward. The compression spring 25 is further compressed. At this time, the push block 26 also blocks the first air pipe 28 that is injected with air to the middle air guide plate 2. The gas is only discharged from the upper air guide plate 2. The wind speed is further increased, and the air cooling effect is further improved. It can ensure that the pressing block 11 can be cooled in a short time while preventing the pressing block 11 from being deformed and cracked due to the too rapid alternation of hot and cold. At this time, the pressing block 11 moves upward. The spring 43 is compressed immediately, and the gas in the cylinder 41 is ejected from the exhaust plate 4 after passing through the second air pipe 42, which can not only cool the mold 12, but also remove impurities on the surface of the support frame 1 and the mold 12. When the pressing block 11 moves downward and punches the next plate, the push frame 22, the connecting rod 24 and the push block 26 gradually move forward and reset under the action of the compression spring 25. The threaded rod 32 and the valve bolt 34 also rotate in the opposite direction and reset. The water valve 35 is gradually closed, and the piston rod of the cylinder 41 also moves downward and resets under the action of the spring 43.

Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
