Description

Technical Field

[0001] The utility model relates to the technical field of metal product processing, in particular to a quick-changing structure for a mold used in metal product processing. Background Art

[0002] Stamping is a forming process that relies on a press and a die to apply external force to plates, strips, pipes, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging are both plastic working (or pressure working), collectively known as forging. The blanks used for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Currently, when installing the upper die of a stamping machine, it is necessary to tighten the nuts. To install the upper die, multiple nuts need to be tightened. However, the staff cannot know whether the nuts are tightened in place, and multiple adjustments are required, resulting in low efficiency in the installation of the upper die. Utility Model Content

[0004] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0005] Preferably, an upper mold is placed on the top of several connecting blocks, one side of each connecting block is fixedly connected to a sliding column, and one end of each sliding column extends into the interior of the fixing frame.

[0006] Preferably, a finger block is fixedly connected to one side of the sliding column, and a first visual scale is fixedly connected to the surface of the fixing frame.

[0007] Preferably, a pointer is fixedly connected to one side of the push block, and a second visual scale is inlaid on one side of the movable rail away from the mounting seat.

[0008] Preferably, one end of each of the studs extends to the outside of the movable rail.

[0009] Preferably, the surfaces of the nuts are in contact with the bottom of the connecting block.

[0010] The utility model provides a quick-change structure for molds used in metal product processing, which has the following beneficial effects:

[0011] 1. The metal product processing mold rapid replacement structure is provided with a stud, a push block and a pointer. The operator uses a tool to twist the stud so that one end of the stud pushes the push block, the fixing frame, the screw and the connecting block to move, so that the connecting block is located below the upper mold. By observing the scale on the second visual scale pointed by the pointer, it is known whether the connecting block has moved into place. Then the operator twists the nut with the tool so that the nut pushes the connecting block upward so that the connecting block contacts the bottom of the upper mold. By observing the movement of the pointer block driven by the sliding column and the scale on the surface of the first visual scale pointed by the pointer, it is known whether the connecting block has moved into place. Therefore, the upper mold is supported by the connecting block, so that it can be known in time whether the connecting block has moved into place without multiple adjustments, thereby improving the efficiency of rapid replacement of the upper mold.

[0012] 2. The metal product processing mold quick replacement structure is provided with a stud, a movable rail and a connecting block. The operator uses a tool to twist the stud so that one end of the stud pushes the push block, the fixing frame, the screw and the connecting block to move, so that the connecting block is located below the upper mold. By observing the scale on the second visual scale pointed by the pointer, it is known whether the connecting block has moved into place. When the upper mold needs to be removed, the operator uses the tool to reset and twist the nut so that the nut pushes the connecting block downward. Then the operator uses the tool to reset and twist the stud so that one end of the stud pushes the push block, the fixing frame, the screw and the connecting block to reset and move, so that the connecting block moves out from under the upper mold, making it convenient to remove, replace and install the upper mold.
