Description

Technical Field

[0001] The utility model relates to the technical field of cold forging, in particular to an easy-to-form niobium alloy cold forging die. Background Art

[0002] Cold forging, also known as cold bulk forming, is a manufacturing process and a processing method. It is basically the same as the cold stamping process. The cold forging process also consists of three elements: materials, molds, and equipment. The only difference is that the materials in stamping are mainly plates, while the materials in cold forging are mainly discs or wires.

[0003] In the existing cold forging technology, the cold forging mold is often not sufficiently protected. When the internal mold core is damaged, the replacement speed is slow, which will affect the subsequent work process. At the same time, the subsequent demolding technology of the mold needs to be improved.

[0004] Therefore, we proposed an easy-to-form niobium alloy cold forging die to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a niobium alloy cold forging die which is easy to form, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an easily formable niobium alloy cold forging die, comprising a cold forging shell and a lower die, wherein the lower die is installed inside the cold forging shell, and a cold forging device is installed on the top of the cold forging shell, wherein the cold forging device comprises a cold forging unit, a discharging unit, and a fixing unit, wherein the cold forging unit is installed on the top of the cold forging shell, the discharging unit is installed inside the cold forging shell, and the fixing unit is installed on the front of the cold forging shell;

[0007] The cold forging unit includes a flip groove, a flip shaft, a positioning column, a flip shell, a movable block, a telescopic part 1, an upper mold, and a positioning groove. The flip groove is opened in the interior of the cold forging shell, the flip shaft is installed in the flip groove, the positioning column is installed on the top of the cold forging shell, the flip shell is installed on the outer surface of the flip shaft, the movable block is installed on the bottom of the flip shell, the telescopic part 1 is installed on the top of the flip shell, the upper mold is installed on the bottom of the telescopic part 1, and the positioning groove is opened at the bottom of the flip shell. By installing the cold forging unit, the material is placed in the interior of the lower mold, and by flipping the flip shell, the flip shell is flipped around the flip shaft, so that the cold forging shell and the flip shell are further fixed by the fixing unit, so that by starting the telescopic part 1, the telescopic part 1 drives the upper mold to start moving downward, so that cold forging starts with the upper mold and the lower mold.

[0008] Preferably, the top of the positioning column is provided with a rounded corner, and the width of the positioning column is the same as the width of the positioning groove, so that the rounded corner can make it easier for the positioning column to enter the interior of the positioning groove, thereby completing the fixation of the flip shell and the cold forged shell.

[0009] Preferably, the discharging unit comprises a telescopic member 2 and a push plate, wherein the telescopic member 2 is installed inside the cold forging housing, and the push plate is installed on the top of the telescopic member 2. By installing the push unit, after the material is cold forged, the telescopic member 2 is started, so that the telescopic member 2 drives the push plate to move.

[0010] Preferably, the fixing unit includes a fixing block, a positioning block, a locking block, a rotating shaft, a connecting plate, a handle, a connecting shaft, and a connecting block. The fixing block is installed on the front side of the cold forging shell, the positioning block is installed on the front side of the flip shell, the locking block is installed on the front side of the fixed block, the rotating shaft is installed inside the locking block, the connecting plate is installed on the outer surface of the rotating shaft, the handle is installed on the bottom of the connecting plate, the connecting shaft is installed on the outer surface of the connecting plate, and the connecting block is installed on the front side of the positioning block. By installing the fixing unit, when the material is placed inside the lower mold, the flip shell is flipped to close the flip shell and the cold forging shell, and the connecting plate is flipped by the handle so that the connecting shaft is located above the notch at the top of the connecting block. After the connecting shaft is aligned with the notch, the handle is pushed in the opposite direction so that the handle drives the connecting plate to start flipping downward, thereby closing the cold forging shell and the flip shell.

[0011] Preferably, the notch at the top of the connecting block is the same width as the connecting shaft, so that the connecting shaft can just enter the groove at the top of the connecting block, thereby preventing the connecting shaft from shaking inside the connecting block groove, resulting in incomplete closure of the cold forging shell and the flip shell, thereby resulting in poor cold forging quality.

[0012] Preferably, the cold forging shell is movably connected to the lower die, and a groove for installing the lower die is provided inside the cold forging shell, thereby preventing the lower die from being damaged and requiring only replacement of the lower die, thereby increasing the repair speed of the device and reducing the impact of the lower die failure on the production speed.

[0013] Preferably, a groove for placing the telescopic part 2 is installed inside the cold forging shell, and the size of the push plate is smaller than the lower die opening of the lower die, so that when the material is cold forged, the push plate can be pushed by the telescopic part 2 to achieve a normal discharge effect.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4The utility model provides a technical solution: an easy-to-form niobium alloy cold forging die, comprising a cold forging shell 101 and a lower die 102, wherein the lower die 102 is installed inside the cold forging shell 101, and a cold forging device is installed on the top of the cold forging shell 101, wherein the cold forging device comprises a cold forging unit, a discharging unit, and a fixing unit, wherein the cold forging unit is installed on the top of the cold forging shell 101, the discharging unit is installed inside the cold forging shell 101, and the fixing unit is installed on the front of the cold forging shell 101;

[0024] The cold forging unit includes a flip groove 201, a flip shaft 202, a positioning column 203, a flip shell 204, a movable block 205, a telescopic member 206, an upper die 207, and a positioning groove 208. The flip groove 201 is opened inside the cold forging shell 101, the flip shaft 202 is installed inside the flip groove 201, the positioning column 203 is installed on the top of the cold forging shell 101, the flip shell 204 is installed on the outer surface of the flip shaft 202, the movable block 205 is installed at the bottom of the flip shell 204, the telescopic member 206 is installed on the top of the flip shell 204, and the upper die 20 7 is installed at the bottom of the telescopic member 206, and the positioning groove 208 is opened at the bottom of the flip shell 204. By installing the cold forging unit, the material is placed inside the lower mold 102, and the flip shell 204 is flipped around the flip axis 202 by flipping the flip shell 204, so that the cold forging shell 101 and the flip shell 204 are further fixed by the fixing unit, so that by starting the telescopic member 206, the telescopic member 206 drives the upper mold 207 to start moving downward, so that cold forging starts through the upper mold 207 and the lower mold 102.

[0025] The top of the positioning column 203 is rounded, and the width of the positioning column 203 is the same as the width of the positioning groove 208. The rounded corner makes it easier for the positioning column 203 to enter the interior of the positioning groove 208, thereby completing the fixation of the flip shell 204 and the cold forging shell 101.

[0026] The material discharging unit includes a telescopic member 301 and a push plate 302. The telescopic member 301 is installed inside the cold forging housing 101, and the push plate 302 is installed on the top of the telescopic member 301. By installing the push unit, after the material is cold forged, the telescopic member 301 is started to drive the push plate 302 to move.

[0027] The fixing unit includes a fixing block 401, a positioning block 402, a locking block 403, a rotating shaft 404, a connecting plate 405, a handle 406, a connecting shaft 407, and a connecting block 408. The fixing block 401 is installed on the front of the cold forging shell 101, the positioning block 402 is installed on the front of the flip shell 204, the locking block 403 is installed on the front of the fixing block 401, the rotating shaft 404 is installed inside the locking block 403, the connecting plate 405 is installed on the outer surface of the rotating shaft 404, the handle 406 is installed on the bottom of the connecting plate 405, and the connecting shaft 407 is installed on the outer surface of the connecting plate 405. The connecting block 408 is installed on the front side of the positioning block 402. By installing the fixing unit, when the material is placed inside the lower mold 102, the flip shell 204 is flipped over to close the flip shell 204 and the cold forging shell 101. The connecting plate 405 is flipped over by the handle 406 so that the connecting shaft 407 is located above the notch at the top of the connecting block 408. After the connecting shaft 407 is aligned with the notch, the handle 406 is pushed in the reverse direction so that the handle 406 drives the connecting plate 405 to start flipping downward, thereby closing the cold forging shell 101 and the flip shell 204.

[0028] The notch at the top of the connecting block 408 is the same width as the connecting shaft 407, so that the connecting shaft 407 can just enter the groove at the top of the connecting block 408, thereby preventing the connecting shaft 407 from shaking inside the groove of the connecting block 408, resulting in incomplete closure of the cold forging shell 101 and the flip shell 204, thereby resulting in poor cold forging quality.

[0029] The cold forging shell 101 is movably connected to the lower die 102, and a groove for installing the lower die 102 is provided inside the cold forging shell 101, so that when the lower die 102 is damaged, only the lower die 102 needs to be replaced, thereby improving the repair speed of the device and reducing the impact of the failure of the lower die 102 on the production speed.

[0030] A groove for placing the telescopic part 2 301 is installed inside the cold forging shell 101, and the size of the push plate 302 is smaller than the lower die opening size of the lower die 102, so that when the material is cold forged, the push plate 302 can be pushed by the telescopic part 2 301 to achieve a normal discharge effect.

[0031] Working principle: Place the material to be cold forged inside the lower die 102, flip the flip shell 204 so that it flips around the flip axis 202, align the positioning column 203 with the positioning groove 208, close the cold forging shell 101 and the flip shell 204, flip the connecting plate 405 through the handle 406, so that the connecting axis 407 is located above the notch at the top of the connecting block 408, align the connecting axis 407 with the notch, push the handle 406 in the opposite direction, so that the handle 406 drives the connecting plate 405 to start flipping downward, thereby closing the cold forging shell 101 and the flip shell 204, start the telescopic member 206, so that the telescopic member 206 drives the upper die 207 to start moving downward, and then start cold forging with the upper die 207 and the lower die 102, and when the cold forging is completed, start the telescopic member 2 301, so that the telescopic member 2 301 drives the push plate 302 to start moving upward, thereby completing the material discharge.
