Abstract

The utility model discloses an edge cutting device of metal strips, which comprises an upper and a lower rotation shafts and an upper and a lower fixing plates, both ends of the upper and the lower fixing plates are fixed on a framework, more than two groups of cutting blades whose distance can be adjusted are arranged on the upper and the lower rotation shafts in match, and the internal cutting edge of the lower end of the upper cutting blade of the upper rotation shaft is matched with the external cutting edge of the upper end of the upper cutting blade of the lower rotation shaft to form the cutting. The device has more reasonable design, stronger cutting force, the cutting edges of the upper and the lower cutting blades are matched for cutting, the damage of the cutting blades is less, and the service life of the cutting blades is obviously improved.

Description

The sheet metal strip trimming device

Technical field:

The utility model relates to the cutting mechanics field, a kind of more precisely trimming device that is used for sheet metal strip.

Background technology:

Sheet metal strip is through behind the pressur rolling forming; both sides are uneven and form some burr and need handle; generally all be to adopt bead cutter that its burr are done to cut edge to handle; existing bead cutter just is provided with blade on last turning cylinder; blade is cut edge to this during sheet metal strip process turning cylinder, and this cutting mode has two shortcomings: the one, and cutting force is not enough, often also is being with the limit to cut off fully; the 2nd, blade damage especially severe, blade needs often to change.

The utility model content:

The purpose of this utility model is to provide a kind of sheet metal strip trimming device that the bottom knife dislocation cooperates cutting of going up, and the cutting force of this device is stronger, the longer service life of blade.

The purpose of this utility model is achieved through the following technical solutions: the sheet metal strip trimming device, comprise that two turning cylinders reach upward bottom plate up and down, the two ends of last bottom plate are fixed on the frame, supportingly on the turning cylinder up and down be provided with two groups of above adjustable blades of spacing, the inner cutter hole of last turning cylinder cutter lower end cooperates formation cutting with outer cutting edge on the following turning cylinder cutter.

Further scheme of the present utility model is, the described inner surface of going up bottom plate also is provided with lower platen, and band is between last lower platen.

By technique scheme as can be seen, sheet metal strip is through out-of-date, the outer cutting edge of the inner cutter hole of last turning cylinder cutter and following turning cylinder cutter cooperates the limit that need prune band to cut, blade cutting edge on the turning cylinder just contacts and certain elasticity is arranged up and down, therefore, when cutting of web, just in time the band cut-out is not damaged blade basically; Because be that up and down blade cutting edge cooperates and finishes cutting, the effect of cutting is very good, do not exist the limit of also ining succession after the cutting not have the phenomenon of cut-out.

The utility model compared with prior art has following beneficial effect: the one, and that designs is more reasonable, and cutting force is stronger; The 2nd, the cutting edge of last bottom knife cooperates cutting, and the damage of blade is less, and obviously improve the service life of blade.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment:

As depicted in figs. 1 and 2, last turning cylinder 2 and following turning cylinder 9 are fixed on the frame, frame is provided with adjusting handle 1, last turning cylinder 2 is provided with two blades 3, following turning cylinder 9 is provided with two blades 10, the inner cutter hole of blade 3 lower ends just contacts to form with the outer cutting edge of blade 10 upper ends and cooperates cutting, the below of last turning cylinder 2 is provided with upper mounted plate 5, the top of following turning cylinder 9 is provided with bottom plate 5a, the two ends of last bottom plate are fixed on the frame by nut 7 and adjusting bolt 8, the lower surface of upper mounted plate 5 is provided with top board 6, the upper surface of bottom plate 5a is provided with lower platen 6a, pass through between the lower platen on the band 4 that needs to cut edge, cutting is finished in the limit of band under the cooperation of last bottom knife.

Claims

1, sheet metal strip trimming device, comprise that two turning cylinders reach upward bottom plate up and down, the two ends of last bottom plate are fixed on the frame, it is characterized in that: supportingly on the turning cylinder up and down be provided with two groups of above adjustable blades of spacing, the inner cutter hole of last turning cylinder cutter lower end cooperates formation cutting with outer cutting edge on the following turning cylinder cutter.

2, sheet metal strip trimming device according to claim 1 is characterized in that: the described inner surface of going up bottom plate also is provided with lower platen, and band is between last lower platen.
