[0028] In this embodiment, when the automobile metal battery box cover is being stamped, the raw material sheet is first placed on the lower die 1 to correspond to the upper die 2, and the press controls the upper die 2 to move downward to close the die with the lower die 1, so as to stamp the raw material sheet. After the automobile metal battery box cover is formed, the upper die 2 moves upward to reset, and then the first lifting cylinder 5 and the second lifting cylinder 6 are started by an external power supply. The first lifting cylinder 5 and the second lifting cylinder 6 simultaneously lift the feeding track 4, and the feeding track 4 enables the stamped automobile metal battery box cover to be taken out from the lower die 1. After the automobile metal battery box cover is taken out, the first lifting cylinder 5 stops moving, and the second lifting cylinder 6 stops moving. The output end of the lifting cylinder 6 continues to move upward, and the feeding track 4 is lifted up through the connecting mechanism. The feeding track 4 is tilted and rotated on the output end of the first lifting cylinder 5, and the limit assembly is opened to allow the formed automobile metal battery box cover to slide down the slope generated by the feeding track 4 to be discharged. The subsequent raw material sheet slides along the slope of the feeding track 4 to between the upper mold 2 and the lower mold 1. The first lifting cylinder 5 and the second lifting cylinder 6 control the feeding track 4 to move downward and reset. The reset feeding track 4 is located in the accommodating groove 3, so that the raw material sheet is placed on the lower mold 1 corresponding to the upper mold 2, and the upper mold 2 is closed again to perform stamping forming of the automobile metal battery box cover.

[0029] Specifically, the feeding track 4 includes a stamping rail 41, a feed rail 42 and a discharge rail 43. The stamping rail 41 is arranged in the accommodating groove 3. The feed rail 42 and the discharge rail 43 are respectively fixedly connected to the symmetrical two side ends of the stamping rail 41, and the bottom end of the discharge rail 43 is movably hinged to the output end of the first lifting cylinder 5 through a hinge shaft.

[0030] In this embodiment, the stamping rail 41 corresponds to the upper die 2 and the lower die 1. When the stamping rail 41 retracts into the accommodating groove 3, the raw material sheet is located on the lower die 1 and corresponds to the upper die 2. When the stamping rail 41 rises, the stamped automobile metal battery box cover can be taken out from the accommodating groove 3. The feed rail 42 is used for placing the raw material sheet, and the discharge rail 43 is used for sliding the automobile metal battery box cover out after stamping.

[0031] Specifically, the connecting mechanism includes a rotating sleeve 71 and a pushing rod 72. The rotating sleeve 71 is hinged to the output end of the second lifting cylinder 6 through a hinge shaft, the pushing rod 72 is fixedly connected to the feed rail 42, and the rotating sleeve 71 is slidably connected to the outer surface of the pushing rod 72.

[0032] In this embodiment, after the first lifting cylinder 5 and the second lifting cylinder 6 lift the feeding track 4, the output end of the second lifting cylinder 6 continues to extend to drive the rotating sleeve 71 to move upward, and the rotating sleeve 71 slides on the surface of the push rod 72 and lifts the feeding track 4, thereby tilting the feeding track 4. The metal battery box cover of the car after stamping on the stamping rail 41 slides out from the discharge rail 43, and the subsequent sheet material slides from the feed rail 42 to the stamping rail 41 for stamping.

[0033] Specifically, the limiting assembly includes two fixed rods 81, two limiting blocks 82, two springs 83 and two pull rods 84. The two fixed rods 81 are fixedly connected to the stamping rail 41 and correspond to the feed rail 42 and the discharge rail 43 respectively. The two limiting blocks 82 are respectively slidably connected to the two fixed rods 81. The two springs 83 are respectively mounted on the outer surfaces of the two fixed rods 81, and the two springs 83 correspond to the two limiting blocks 82 respectively. The two pull rods 84 are respectively fixedly connected to the two limiting blocks 82.

[0034] In this embodiment, the limit block 82 close to the discharge rail 43 blocks the formed automobile metal battery box cover, and the limit block 82 close to the feed rail 42 separates the automobile metal battery box cover and the sheet material. When the formed automobile metal battery box cover needs to slide out from the discharge rail 43, the right limit block 82 slides on the right fixed rod 81 by pulling the pull rod 84 on the right side, and squeezes the right spring 83, so that the right limit block 82 does not restrict the formed automobile metal battery box cover, and the formed automobile metal The battery box cover slides out from the discharge rail 43, and the right pull rod 84 is loosened to reset the right limit block 82 through the elastic force of the right spring 83. After the reset is completed, the left pull rod 84 is pulled, and the left pull rod 84 moves the left limit block 82. The left limit block 82 does not restrict the sheet material, so that the sheet material slides into the stamping rail 41. The right limit block 82 restricts the sheet material, so that the sheet material is stabilized in the stamping rail 41. The stamping rail 41 places the sheet material on the lower mold 1 and stamps it corresponding to the upper mold 2.

[0035] Specifically, a group of rollers 9 are rotatably connected to the feed rail 42 and the discharge rail 43, and each group of rollers 9 is provided with a plurality of rollers.

[0036] In this embodiment, two sets of rollers 9 are used to make it smoother for the sheet material to enter the stamping rail 41 and for the automobile metal battery box cover to slide out of the stamping rail 41, thereby facilitating the insertion and removal of the automobile metal battery box cover during the molding process.

[0037] Working principle: When the automobile metal battery box cover is being stamped, the raw material sheet is first placed on the lower die 1 corresponding to the upper die 2, and the press controls the upper die 2 to move downward and close the die with the lower die 1, so as to stamp the raw material sheet. After the automobile metal battery box cover is formed, the upper die 2 moves upward and resets, and then the first lifting cylinder 5 and the second lifting cylinder 6 are started by an external power supply, and the first lifting cylinder 5 and the second lifting cylinder 6 simultaneously lift the feeding track 4, and the stamping rail 41 makes the stamped automobile metal battery box cover be taken out from the lower die 1. After the automobile metal battery box cover is taken out, the first lifting cylinder 5 stops moving, and the output end of the second lifting cylinder 6 continues to extend to drive the rotating sleeve 71 to move upward, and the rotating sleeve 71 slides on the surface of the push rod 72 and lifts the feeding track 4, thereby tilting the feeding track 4, and then, pull the pull rod 84 on the right side to make the right limit block 82 The molded automobile metal battery box cover slides out from the discharge rail 43, and the pull rod 84 on the right is released to reset the right limit block 82 through the elastic force of the right spring 83. After the reset is completed, the pull rod 84 on the left is pulled, and the pull rod 84 on the left moves the left limit block 82. The left limit block 82 does not limit the sheet material, so that the sheet material slides from the feed rail 42 to the stamping rail 41. The limit block 82 on the right limits the sheet material, so that the sheet material is stabilized in the stamping rail 41. The first lifting cylinder 5 and the second lifting cylinder 6 control the feeding rail 4 to move downward and reset. The reset stamping rail 41 is located in the accommodating groove 3, so that the raw material sheet is placed on the lower mold 1 corresponding to the upper mold 2, and the upper mold 2 is closed again to perform stamping forming of the automobile metal battery box cover.

[0038] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
