Description

Four-hole stamping die for engine heat shield

Technical Field

The utility model relates to a stamping die technical field especially relates to an engine separates four holes stamping die of heat exchanger.

Background

The stamping is a forming method in which a press and a die are used to apply an external force to a plate, a strip, a pipe, a profile, or the like to cause plastic deformation or separation, thereby obtaining a workpiece (a stamped part) having a desired shape and size. Stamping and forging are plastic working (or called pressure working), and are called forging and pressing. The stamped blanks are mainly hot and cold rolled steel sheets and strips. In the world, 60-70% of steel materials are plates, and most of the plates are punched to form finished products. The body, chassis, oil tank, radiator sheet, boiler steam drum, shell of container, iron core silicon steel sheet of motor and electric appliance are all made by punching. There are also a large number of stamped parts in products such as instruments, household appliances, bicycles, office machines, and household utensils. Compared with castings and forgings, the stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with ribs, undulations or beads that are otherwise difficult to manufacture, to increase their rigidity. Because of the adoption of the precise die, the precision of the workpiece can reach the micron level, the repeated precision is high, the specification is consistent, and the hole nest, the boss and the like can be punched. Cold stamped parts are generally no longer machined or only require a small amount of machining. The precision and the surface state of the hot stamping part are lower than those of a cold stamping part, but are still better than those of a casting and a forging, and the cutting processing amount is small. Although the punching is widely used in machinery, some defects still exist in the processing of some special parts, the shape of the engine heat shield is not very regular, so the labor amount is increased in the punching process, at present, most of the existing punching methods adopt a mode of punching one by one, because holes are not arranged together, a workpiece needs to be turned over, the punching times are increased, the automation degree is not high, the workpiece cannot be automatically positioned, the holes can be punched out in a biased way if not careful, the workpiece is scrapped, the processing efficiency is reduced, the production cost is increased, and therefore, much inconvenience exists in the actual processing. Therefore, the four-hole stamping die for the engine heat shield is provided.

SUMMERY OF THE UTILITY MODEL

The utility model provides a four hole stamping die of engine heat shield aims at fixing anomalous engine heat shield through a plurality of bracing pieces, lets more accurate of punching press to cushion the die cutter through the spring and pop out convenient clearance to the residual material after the punching press.

The utility model provides a specific technical scheme as follows:

the utility model provides a pair of engine separates four hole stamping die of heat exchanger, including the lower bolster, lower bolster surface fit sliding connection has the bracing piece, bracing piece skin weld has big spring, the threaded rod is all installed at both ends about the lower bolster surface, threaded rod surface opposite side cooperation rotation is connected with cowl, the welding of lower bolster inner wall has concave groove, concave groove skin weld has the pin, pin surface mounting has the spring, pin surface fit sliding connection has the die cutter, the die cutter inner wall is installed and is blockked the piece.
