Needs in production.Therefore, it is necessary to a kind of new shear knife.
Utility model content
The purpose of this utility model is to provide the shear knife on a kind of plate shearing machine, and the utility model is rational in infrastructure simple, raw
Produce it is easy to manufacture, the dovetail excrescence with step blade be engaged with the dovetail groove with step cutter hub realization band step cutter hub and band
The connection of step blade, connection is reliable, and stability is high, can greatly improve crudy and operating efficiency；In shearing overlength metal
Used during thin plate, more smooth sheet metal can be obtained.
The purpose of this utility model is achieved through the following technical solutions, the shear knife on a kind of plate shearing machine, including knife
Body and blade body, cutter hub are band step cutter hub, and band step cutter hub end is step-like, and blade body includes multiple band step knives
Sword, band step cutter hub are engaged with step blade, and described band step blade one end is step-like, and the band step blade other end is
Triangle, it is characterized in that, it is described multiple for counteredge body with being uniformly provided with step cutter hub stage portion length direction
Dovetail groove；Stage portion with step blade is provided with dovetail excrescence, the dovetail excrescence with step blade with step cutter hub
Dovetail groove is engaged realization with step cutter hub and the connection with step blade.
Preferably, the band step cutter hub is carbon structural steels cutter hub.
Preferably, the band step blade is carbon tool steel blade.
Preferably, the edge of a knife with step blade is the edge of a knife by Quenching Treatment.
Preferably, the blade cutter hub that the multiple blade with the level is formed is serrated.
Compared with prior art, the utility model has the advantages that：
First, by processing dovetail groove in the stage portion with step cutter hub, swallow is provided with the stage portion with step blade
Stern counter, the dovetail excrescence with step blade are engaged realization band step cutter hub with the dovetail groove with step cutter hub and with platforms
The connection of rank blade, using the cooperation of dovetail excrescence and dovetail groove, connection is reliable, is inserted directly into and fixes, easy to use,
The set-up time is saved.
Second, cutter hub with the level and multiple blades with the level form the utility model shear knife, rational in infrastructure simple,
It is easy to manufacture, and cost is low, has wide market prospects.
3rd, used when shearing overlength sheet metal, more smooth sheet metal can be obtained, processing can be greatly improved
Quality and operating efficiency.
Brief description of the drawings
Fig. 1 is the front view of the shear knife on the utility model plate shearing machine；
Fig. 2 is the left view of the shear knife on the utility model plate shearing machine；
In figure：1 hole being connected with plate shearing machine, 3 are with step cutter hub, 4 edges of a knife with step blade, 5 band step blades, 6 swallows
Stern notch, 7 dovetail excrescences.
Embodiment
As shown in Figure 1-2, the shear knife on a kind of plate shearing machine, including cutter hub and blade body.
Cutter hub is band step cutter hub 3, and the end of band step cutter hub 3 is step-like, and blade body includes multiple band step blades
5, band step cutter hub 3 is engaged with step blade 5.
Band step blade one end is step-like, and the band step blade other end is triangle, the stage portion of band step cutter hub 3
Multiple dovetail grooves 6 for counteredge body are uniformly provided with length direction；Stage portion with step blade is dashed forward provided with dovetail
Go out body 7, the dovetail excrescence 7 with step blade is engaged realization band step cutter hub 3 with the dovetail groove 6 with step cutter hub and with platform
The connection of rank blade 5.
Preferably, the band step cutter hub 3 is carbon structural steels cutter hub.
Preferably, the band step blade 5 is carbon tool steel blade.
Preferably, the edge of a knife 4 with step blade is the edge of a knife by Quenching Treatment.
Preferably, the blade cutter hub that the multiple blade with the level 5 is formed is serrated.
Cutter hub with the level and multiple blades with the level form the utility model shear knife, rational in infrastructure simple, production
Easy to manufacture, cost is low, has wide market prospects.Use, can obtain more smooth when shearing overlength sheet metal
Sheet metal, crudy and operating efficiency can be greatly improved.
A step is processed on a metal plate using milling machine to be formed with step cutter hub 3, using drilling machine on band step cutter hub 3
Process two holes being connected with plate shearing machine 1 and the multiple dovetail grooves 6 being connected with step blade, using linear cutting equipment in gold
