Description

A kind of shear knife on plate shearing machine
Technical field
It the utility model is related to the new shear knife on a kind of plate shearing machine, especially a kind of overlength sheet metal of shearing New shear knife on plate shearing machine, belongs to machining technology field.
Background technology
Some overlength sheet metal shearings, the matter of overlength sheet metal shearing are frequently encountered in machining Amount and efficiency, largely relevant with the shear knife on plate shearing machine, the shear knife on existing plate shearing machine is in overlength metal foil During plate shearing, the overlength sheet metal being sheared is also easy to produce torsion phenomenon, causes poor product quality, it is impossible to meets that reality is raw 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 An oblique line is processed on category plate to form band step blade 5, form dovetail on band step cutter hub in band step blade 5 using drilling machine Excrescence 7, the edge of a knife 4 is worn on the oblique line with step blade 5 using grinding machine, the edge of a knife 4 quench ground again with grinding machine it is sharp, will be with platform High point on rank blade 5 leans on high point, and two one group, low spot is mounted in low spot on band step cutter hub 3 between group and group, and dovetail is dashed forward Go out new shear knife of the body 7 in dovetail groove 6 on a kind of composition plate shearing machine of the utility model.
It is connected during use by hole 1 on the new shear knife on a kind of plate shearing machine of the utility model with plate shearing machine, is being sheared Plate shearing machine is started during overlength sheet metal, it becomes possible to obtains more smooth sheet metal.
A kind of new shear knife on plate shearing machine uses zigzag design, and it has band step cutter hub and multiple band step blades Composition, band step cutter hub material carbon structural steels, band step blade change steel alloy, quenching cutting edge, cutter hub with carbon tool steel On have multiple dovetail grooves, have dovetail excrescence on blade, it is new that cutter hub with the level and multiple blades with the level form this practicality Shear knife in type, more smooth sheet metal, the utility model structure can be obtained when shearing overlength sheet metal, during use Rationally simple, it is easy to manufacture, and cost is low to have wide market prospects.
