Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal material production and processing, in particular to a stamping lower grinding tool capable of quickly replacing or repairing a die. Background Art
[0002] Stamping dies are specialized equipment used in cold stamping to process materials into parts (or semi-finished products). Stamping is a process in which a die mounted on a press applies pressure to the material at room temperature, causing it to separate or plastically deform, thereby producing the desired part. Stamping dies are essential equipment for stamping production. The quality, efficiency, and cost of stamped parts are directly related to die design and manufacturing.
[0003] When the existing stamping die is used for a long time, problems such as damage to the die cutting edge will inevitably occur in the punching of the lower die, resulting in burrs, recessed apertures and other problems after the product is punched out. When problems such as die cutting edge damage occur, the die needs to be repaired or replaced. However, the existing stamping die adopts an integrated structure, which is inconvenient to disassemble, repair and clean, resulting in increased maintenance costs for the entire lower die. Summary of the Invention
[0004] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a stamping lower mold that can quickly replace or repair the die.
[0005] The purpose of the utility model is achieved through the following technical solutions: A stamping lower mold capable of quickly replacing or repairing a die, comprising a lower die base, a die base provided in the middle of the upper end of the lower die base, a die mounting hole provided in the middle of the die base, a limiting step provided on the side wall of the die mounting hole, a die provided in the die mounting hole, a gasket provided between the bottom of the die and the limiting step, a notch provided on the upper end side wall of the die mounting hole, a limiting assembly installed on the notch to limit the removal of the die from the die mounting hole. The limiting assembly is located on one side of the die and can limit the removal of the die. When the die needs to be replaced or polished and repaired, the die can be removed after disassembling the limiting assembly. The gasket is made of sheet metal or alloy material. There can be multiple gaskets, and the number and thickness can be selected according to the size of the die worn during polishing and repair.
[0006] As an improvement to the present invention's lower die for stamping, which allows for quick replacement or repair of the die, the limiting assembly includes a pressure block and a limiting screw. The pressure block is secured to the notch via the limiting screw. The pressure block is provided with a screw countersunk hole, through which the limiting screw passes and is screwed into the notch. To disassemble the die, simply remove the limiting screw.
[0007] As an improvement of the punching lower mold capable of quickly replacing or repairing the die of the utility model, one side of the pressing block extends into the die mounting hole, and the pressing block can press the die to restrict the removal of the die.
[0008] As an improvement of the stamping lower mold of the utility model that can quickly replace or repair the die, a supporting step is provided on one side of the die, and the protruding part of the pressing block supports the supporting step to limit the removal of the die.
[0009] As an improvement to the punching lower mold of the utility model that enables quick replacement or repair of the die, the die is provided with a blanking through-hole in the middle, and the lower die base is provided with a discharge hole in the middle, the blanking through-hole being connected to the discharge hole. The stamped waste will fall from the blanking through-hole into the discharge hole.
[0010] The beneficial effect of this utility model lies in that a limiting step is provided on the side wall of the die mounting hole. The limiting step is used to support the gasket and the die. The thickness of the die worn away during grinding and maintenance can be compensated by the gasket, so that the height of the die remains flush with the upper end of the die base. The die is fixed and removed by the limiting assembly, which simplifies disassembly and facilitates die replacement, grinding and maintenance, etc. BRIEF DESCRIPTION OF THE DRAWINGS
