Abstract
The utility model relates to the technical field of die machining, in particular to a notching press used for notching machining of a U-shaped workpiece. The notching press comprises an upper die and a lower die which are arranged up and down, the bottom of the upper die is connected with a plurality of locating rods, the middle portion of the bottom end of the upper die is provided with a cylindrical punch, the lower die is provided with a plurality of locating pipes matched with the locating rods, the middle portion of the lower die is provided with a U-shaped groove, two sides of the bottom of the U-shaped groove are provided with circular channels, and a plurality of elastic supporting bases are symmetrically arranged at the bottom end of the lower die. The notching press used for the notching machining of the U-shaped workpiece is reasonable in structural design and improves precision of the notching machining due to the design of the locating rods and spring bushes. Due to the design of the elastic supporting bases at the bottom of the lower die, impact of the notching press is remarkably reduced, and therefore service life of the notching press is prolonged. Due to arrangement of the circular channels, echoes caused by stamping are effectively lowered and production noise is remarkably lowered.
Description
Technical field
The utility model relates to the mold machining technology field, specifically relates to a kind of notching press for the processing of U-shaped workpiece jet-bedding.
Background technology
The U-shaped workpiece mainly is stamping forming by notching press.There are the defectives such as machining accuracy is low, noise is large in existing notching press.
Summary of the invention
For the technical problem that exists in the prior art, the utility model provides a kind of notching press for the processing of U-shaped workpiece jet-bedding.
To achieve these goals, the technical scheme of employing is as follows:
A kind of notching press for the processing of U-shaped workpiece jet-bedding is characterized in that, has to go to upper and lower the upper die and lower die of arranging,
The patrix bottom is connected with several backstays, and the patrix center bottom is provided with cylindrical drift;
Counterdie is provided with several positioning pipes that cooperates with backstay, and the counterdie middle part is provided with the U-shaped die, and the two bottom sides of U-shaped die is equipped with annular channel;
The bottom of counterdie is symmetrically distributed with several elastic supporting seats.
The utility model is used for the notching press of U-shaped workpiece jet-bedding processing, and reasonable in design by backstay and pogo barrel design, has improved the precision of jet-bedding processing.By the elastic supporting seat design of counterdie bottom, can significantly reduce the impact of notching press, and then the service life of improving notching press.By the design annular channel, can effectively reduce the echo that punching press forms, can significantly reduce the production noise.
Description of drawings
