Abstract
The utility model discloses a knife edge assembling punching drill, which comprises a knife shaft, the drill and an annular knife, wherein the annular knife is sheathed on the knife shaft, the annular knife is composed of a front knife body and a back knife body, the front knife body is connected with the back knife body in a detachable way, the front end margin of the front knife body is the knife edge and the whole annular knife is sheathed on the knife shaft through the back knife body. Since the knife edge of the utility model is arranged at the front end margin of the front knife body, only the front knife body adopts high hardness rigid material and the back knife body adopts ordinary hardness rigid material. In this way, the product cost is reduced greatly. Simultaneously, when annular knives with different tooth shapes and caliber sizes are need to use, only the front knife body to be replaced, namely, the back knife body is matched with a plurality of front knife bodies with different kinds. The utility model not only reduces the product cost further, but also saves the storage space. The utility model is suitable for punching the rigid material, such as metal, iron, etc.
Description
Technical field
The utility model relates to a kind of perforate utensil, relates in particular to a kind of super hole cutter that is used for hard materials such as metallic iron.
Background technology
Be used for the super hole cutter of hard materials such as metallic iron at present, as shown in Figure 1, be made of cutter shaft 1, drill bit 2 and endless knife 3 usually, wherein endless knife 3 is integrative-structure, and its front edge has cutter tooth.Owing to be that hard substrates such as metallic iron are constructed, therefore higher to the performance requirements such as hardness of making endless knife 3 material therefors, and endless knife 3 is integrative-structure, and whole parts all adopt performance requirement and the higher material of price, certainly will increase the cost of product like this.In addition, when needs use the endless knife 3 of dissimilar tooth form, different caliber size, must replace whole parts.Endless knife owing to must have variety classes and size at different operations has so not only increased the cost of product, and has increased the space that stores.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and providing a kind of can reduce product cost significantly, is convenient to change and use, and can saves the edge of a knife assembled super hole cutter of storage area.
The purpose of this utility model is achieved by the following technical programs:
A kind of edge of a knife assembled super hole cutter that the utility model provides comprises cutter shaft, drill bit and endless knife, and wherein endless knife is sleeved on the cutter shaft; Described endless knife is made of preceding cutter hub and back cutter hub, and cutter hub is detachable links together for preceding cutter hub and back, and the front edge of preceding cutter hub is the edge of a knife, and the full annular cutter is sleeved on the cutter shaft by cutter hub thereafter.Because the front edge of cutter hub before the edge of a knife is located at, therefore only preceding cutter hub adopts the high rigidity rigid material, and then cutter hub adopts common hardness rigid material to get final product, and has so just reduced product cost significantly.Simultaneously, when needs used the endless knife of dissimilar tooth form, different caliber size, cutter hub get final product before only changing, promptly after one cutter hub can cooperate a plurality of different types of before the cutter hubs uses, not only further reduced product cost, but also saved the storage area.
Detachable connection before described in the utility model between cutter hub and the back cutter hub is advisable to be threaded, and also can adopt other as types of attachment such as clampings in addition.When employing is threaded, described in the utility model before the outside of cutter hub and the inboard of back cutter hub be respectively equipped with corresponding helicitic texture, promptly before cutter hub be enclosed within the cutter hub of back; Perhaps, described before the inboard of cutter hub and the outside of back cutter hub be respectively equipped with corresponding helicitic texture, promptly before cutter hub be enclosed within outside the cutter hub of back.
The edge of a knife at the front edge place of cutter hub is a dentation before described in the utility model.
The utlity model has following beneficial effect: the preceding cutter hub of endless knife and back cutter hub can adopt the material of different hardness to make, and can reduce product cost significantly.Cutter hub can cooperate a plurality of different types of preceding cutter hubs to use after one, not only is convenient to change and operation, and has further reduced product cost, and saved the storage area.

The specific embodiment
Embodiment one:
Fig. 2～Figure 5 shows that one of embodiment of the present utility model comprises cutter shaft 1, drill bit 2 and endless knife 3, and as shown in Figure 2, the rear portion of drill bit 2 is plugged in the cutter shaft 1.Endless knife 3 is made of preceding cutter hub 31 and back cutter hub 32, as shown in Figure 3, the front edge of the edge of a knife 4 cutter hub 32 for dentation and before being located at, the outside of preceding cutter hub 31 is provided with external thread structure.As shown in Figure 4, the inboard of back cutter hub 32 is provided with and preceding cutter hub 31 corresponding adaptive female thread structures, and the middle part of back cutter hub 32 bottom surfaces is provided with sleeve joint hole 5.
As shown in Figure 5, preceding cutter hub 31 thread bush are connected in the cutter hub 32 of back and looping cutter 3.Full annular cutter 3 is threaded in the front end (see figure 2) of cutter shaft 1 by the sleeve joint hole 5 of back cutter hub 32.
In addition, the connection between preceding cutter hub 31 and the back cutter hub 32 also can adopt other as types of attachment such as clampings.
Preceding cutter hub 31 adopts the high rigidity rigid materials, and back cutter hub 32 adopts common hardness rigid material.When needs used the endless knife of dissimilar tooth form, different caliber size, cutter hub 31 get final product before only changing, promptly after one cutter hub 32 can cooperate a plurality of different types of before cutter hubs 31 uses.
Embodiment two:
Present embodiment and embodiment one difference are: as shown in Figure 6, the outside of the inboard of cutter hubs 31 and back cutter hub 32 is provided with corresponding helicitic texture before the endless knife 3, and preceding cutter hub 31 thread bush are connected on the outer and looping cutter 3 of back cutter hub 32.
