Abstract
The utility model discloses a hole flanging drift punches a hole, including the drift body, the bottom of drift body has portion of punching a hole and hole flanging portion respectively, hole flanging position in the top of the portion of punching a hole, and the portion of punching a hole is the cylindricality structure, and its tip has sharp form portion, and hole flanging portion is big -end -up's toper structure. The utility model discloses simple structure can once only accomplish and punch a hole and the hole flanging process, has effectively improved production efficiency, greatly reduced the cost of each links such as personnel, board and the charges of electricity, strengthened the intensity of drift and the firmness in the stamping process in addition, solved the problem of repeated maintenance, and can accomplish once only that punch a hole and the technology of hole flanging is just led, guaranteed the concentricity of product to product quality has been guaranteed.
Description
Technical field
The utility model relates to the accessory field of auto parts and components production and processing mould, specifically a kind of punching hole flanging punch.
Background technology
In auto parts and components process of manufacture, original drift realizing workpiece punching and hole flanging is divided into two kinds, i.e. pierce punch and hole flanging punch, is arranged on respectively on the mould in two procedures, reduces production efficiency undoubtedly; In addition, punch diameter is little often easily to fracture, and makes the mould maintenance rate that rolls off the production line in process of production high, and, need respectively to carry out technique correcting after punching and hole flanging, make product concentricity poor, thus have impact on the quality of product.
Utility model content
The purpose of this utility model is to provide a kind of punching hole flanging punch, disposablely can complete punching and hole flanging operation, to enhance productivity, reduces maintenance rate, and ensures the quality of product.
The technical solution of the utility model is as follows:
A kind of punching hole flanging punch, include drift body, it is characterized in that: the bottom of described drift body has punching portion and hole flanging portion respectively, described hole flanging portion is positioned at the top in described punching portion, described punching portion is column construction, its end has pointed section, and described hole flanging portion is up big and down small pyramidal structure.
Described punching hole flanging punch, is characterized in that: described hole flanging portion and described punching portion and the transition position between hole flanging portion and described drift body are respectively equipped with arc angling.
The beneficial effects of the utility model:
The utility model structure is simple, disposablely can complete punching and hole flanging operation, effectively improve production efficiency, greatly reduce the cost of the links such as personnel, board and the electricity charge, enhance the intensity of drift and the firmness in punching course in addition, solve the problem repeating to keep in repair, and disposablely can complete the technique correcting of punching and hole flanging, ensure that the concentricity of product, thus ensure that product quality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
See Fig. 1, a kind of punching hole flanging punch, includes drift body 1, the bottom of drift body 1 has punching portion 2 and hole flanging portion 3 respectively, and hole flanging portion 3 is positioned at the top in punching portion 2, and punching portion 2 is column construction, its end has pointed section, and hole flanging portion 3 is up big and down small pyramidal structure.
In the utility model, hole flanging portion 3 and punching portion 2 and the transition position between hole flanging portion 3 and drift body 1 are respectively equipped with arc angling 4.
Empirical tests, adopts that the utility model is disposable completes punching and hole flanging operation, improves the production efficiency of about 1/5th, the links such as personnel, board and the electricity charge have been saved the cost of about 20 percent.
