Stamping die

Abstract

The invention discloses a stamping die. The stamping die comprises a base 1, the base 1 is connected with an upper die base 2 and a lower die base 3 in a sliding mode, the lower die base 3 and the upper die base 2 are provided with a supporting rod 4 and a sliding frame 5 respectively, the supporting rod 4 and the sliding frame 5 are slidably connected to the base 1 in the vertical direction through a first sliding assembly and a second sliding assembly correspondingly; a first linear rack is arranged on the supporting rod 4, a first gear 6 is rotationally connected to the base 1, a plug rod 8is slidably connected to the base 1, and a second linear rack is arranged on the plug rod 8; and a valve seat 10 is arranged on the base 1, and the plug rod 8 is slidably connected to one end of thevalve seat 10, the other end of the valve seat 10 is provided with a first oil inlet 11, the valve seat 10 is sequentially provided with a first cavity 12, a second cavity 13 and a third cavity 14 from the plug rod 8 to the first oil inlet 11, wherein the first cavity 12, the second cavity 13 and the third cavity 14 allow hydraulic oil to flow, the first cavity 12 communicates with the second cavity 13 through a transition flow channel 15, and the end part of the plug rod 8 is provided with a first piston 16. According to the stamping die, the automation level is higher, and the machining precision is higher.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a stamping die. Background technique [0002] Stamping die is a process equipment for processing metal or non-metallic materials into parts in cold stamping; specifically, at room temperature, using a die installed on a press to apply pressure to the material to cause separation or Plastic deformation, and then a pressure processing method to obtain the desired structure. The setting of the power source is to purchase presses of different specifications or models according to the needs of different working conditions. The output end of the press is connected with the lower mold base for placing the blank and the upper mold base for the stamping action; however, after stamping the general blank, the workpiece undergoes plastic deformation, because once the blank loses external force after deformation, the blank There will be a certain amount of rebound. For example, when a ...

Problems solved by technology

The output end of the press is connected with the lower mold base for placing the blank and the upper mold base for the stamping action; however, after stamping the general blank, the workpiece undergoes plastic deformation, because once the blank loses external force after deformation, the blank There will be a certain amount of rebound. For example, when a metal part is processed by a stamping die to process a U-shaped part, once the upper mold base and the lower mold base are parted, the opening of the U-shaped part will expand outwards to form a bell-shaped structure. It is impossible to ensure that the flanges on both sides of the punching opening are parallel workpieces; that is to say, the stamping dies in the prior art have the deficiency of low machining accuracy; low level
