[0002] As we all know, sheet metal refers to the processing operations such as shearing, punching, and welding of thin metal plates. The products produced by sheet metal technology are called sheet metal parts. In the process of automobile manufacturing, various body sheet metal parts are needed. When producing body sheet metal parts, stamping dies are needed for processing.

[0003] When installing traditional stamping dies, mechanical auxiliary equipment such as cranes and forklifts are generally used to move and transport the dies. However, due to the different models of body sheet metal parts produced, the stamping dies are not easy to move and accurately position during installation. The subsequent precise positioning mainly relies on manual movement of the dies, which increases the workload of manual handling, resulting in low installation efficiency of the stamping dies and reduced efficiency of body sheet metal production.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

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.

[0024] See also Figure 1-4, a stamping die for the production of body sheet metal parts, comprising a lower die 1, an upper die 2, an adjusting device and a movable plate 3, the top of the lower die 1 is movably connected with the upper die 2, the lower die 1 is provided with a receiving cavity 4 with a lower opening, the movable plate 3 is installed in the receiving cavity 4 through the adjusting device, and the bottom wall of the movable plate 3 is provided with a plurality of evenly arranged balls 5, the adjusting device comprises a threaded rod 6, a slider 7 and a driving device, the left and right side walls of the receiving cavity 4 are provided with rectangular grooves 8, the threaded rod 6 is rotatably installed in the rectangular groove 8, the slider 7 is installed on the threaded rod 6, and the two groups of the sliders 7 are fixedly connected to the left and right side walls of the movable plate 3. In this embodiment, when in use, when the mold needs to be installed, the upper die 2 and the lower die 1 are first hoisted to the vicinity of the specified position by the auxiliary device, and then the driving device is started, and the driving device drives the two groups of threaded rods 6 to rotate simultaneously, and the two groups of threaded rods Under the action of simultaneous rotation, the threaded rods 6 drive the two groups of sliders 7 to move linearly in the two groups of rectangular grooves 8. The two groups of sliders 7 drive the fixedly connected movable plate 3 to move downward, so that the ball 5 at the bottom of the movable plate 3 contacts the mounting surface. The worker can push the lower mold 1 to drive the ball 5 to move on the mounting surface. The ball 5 will roll on the mounting surface instead of sliding. The rolling friction is much smaller than the sliding friction. Therefore, the force required for movement can be significantly reduced, making the lower mold 1 easier to move. When positioned at the position where installation is required, the drive device is started to drive the two groups of threaded rods 6 to rotate in the opposite direction. When rotating in the opposite direction, the two groups of threaded rods 6 drive the two groups of sliders 7 and the connected movable plate 3 to move upward in the rectangular groove 8 until the ball 5 leaves the mounting surface, so that the lower mold 1 contacts the mounting surface. The lower mold 1 can be installed on the mounting surface. When maintenance or replacement is required, it can be easily disassembled and reinstalled. This design simplifies the maintenance and replacement process of the mold and reduces maintenance costs.

[0025] In actual use, it is further convenient to make the driving device drive the two groups of threaded rods 6 to rotate simultaneously. In this embodiment, the driving device includes a driven bevel gear, a driving bevel gear, a rotating shaft, a driving shaft and a driving motor.

The left and right output ends of the driving motor 13 simultaneously drive the driving shafts 12 connected at both ends to rotate. The driving shafts 12 drive the two fixedly connected active bevel gears 10 to rotate. The two active bevel gears 10 drive the two meshing driven bevel gears 9 to rotate. The two driven bevel gears 9 drive the two rotating shafts 11. The two rotating shafts 11 drive the two threaded rods 6 to rotate simultaneously during the rotation process. The forward and reverse rotation of the driving motor 13 can realize the simultaneous forward and reverse rotation of the two threaded rods 6.
