[0002] At present, when most molds are produced, there will be punching holes on the product. When the product is deformed or the design is changed, the position of the punching hole will change. At this time, it is necessary to replace the punch holder and the die. The sleeve fixing seat is removed and re-grinded, and then the gasket is re-added to ensure the offset of the position. In this case, the punch and the die sleeve can be moved, but in most cases these two are not movable. , and the amount of processing in this case increases, and the operation is more cumbersome

Embodiment Construction
[0012] Such as figure 1 , figure 2 As shown, this patent application includes: upper template, punch backing plate, punch holder, punch, die sleeve, die holder holder, adjustment plate, die holder backing plate, and lower die plate; punch backing plate Installed on the back of the upper template and fixed on the upper surface of the punch holder with flat-head bolts. One end of the punch is suspended and the other end is locked on the punch pad through the punch holder. The side of the punch pad is installed with two symmetrical Two adjusting plates, which are fixed by flat-head bolts, the above-mentioned components constitute the upper die assembly, and the operation of the upper die plate drives the axial movement of the punch;
[0013] A die cover plate is installed on the lower template. A die holder is installed above the die cover plate and fixed with flat-head bolts. Two symmetrical adjusting plates are installed on the outer side of the die holder, and the flat head is u...

The invention discloses a position deviation mechanism for a die punch and a female die sleeve. The position deviation mechanism for the die punch and the female die sleeve comprises an upper die assembly and a lower die assembly, wherein in the upper die assembly, one end of the punch is suspended, the other end of the punch is mounted on a punch fixing base, and an adjustable adjustment plate ismounted on the side face of the punch fixing base and connected with the upper die plate through a punch base plate; and in the lower die assembly, the bottom of a female die sleeve fixing base is mounted on the lower die plate through a female die sleeve base plate, an adjustable adjustment plate is mounted on the outer side face of the female die sleeve fixing base, a through hole is formed inthe center of the female die sleeve fixing base and located below the punch and is coaxial with the punch, and the female die sleeve is embedded into the through hole. In use, by changing the thickness of the adjustment plate on one side of the female die fixing base, the thickness of the adjustment plate on the other side is increased or decreased accordingly, and thus position deviation betweenthe punch and the female die sleeve is achieved; and the position deviation mechanism for the die punch and the female die sleeve is simple and ingenious in structure, convenient to operate, short inmaintenance time and high in practicability, production efficiency is improved, and cost is reduced.
Description
Technical field [0001] The invention belongs to the technical field of stamping dies, and in particular relates to a position offset mechanism of a die punch and a female die sleeve, which realizes rapid on-site mold maintenance. Background technique [0002] At present, when most molds are in production, there will be punching holes on the product. When the product is deformed or the design is changed, the position of the punching hole will change. At this time, the punch holder and the die must be fixed. Remove the sleeve holder and re-grind and add a gasket to ensure the position offset. In this case, the punch and the die sleeve can move, but in most cases these two are not movable. And the processing volume in this case is increased, and the operation is more complicated. Summary of the invention [0003] This patent application provides a mechanism for shifting the position of the die punch and the die sleeve. The original die structure is modified, and the gasket is design...
