Description

Bamboo chip cracks cutter

Technical field

The utility model relates to a kind of bamboo chip and to crack cutter.

Background technology

In order to make full use of the resource of the Nature, simultaneously in order to meet the ever-increasing demand of people, bamboo product obtains a wide range of applications, wherein, the processing of bamboo plate is an important link, in order to bamboo chip is processed into bamboo plate, the bamboo chip of arc-shaped is needed to offer the dense line of rabbet joint, arc-shaped can be launched into plane on the one hand, glue can be injected the line of rabbet joint on the other hand, utilize glue to be bonded together by multiple layered bamboo and form thicker larger bamboo plate, the shape of the cutter of fluting, be directly connected to the shape of the line of rabbet joint, offer the intensity of the bamboo chip of the line of rabbet joint, the line of rabbet joint opened of existing cutter due to the bamboo silk cut out more, the utilization rate of bamboo is lower, it is more that the muscle stayed after fluting seam fractures, intensity is caused to decline.

Utility model content

The utility model, according to above not enough, provide a kind of bamboo chip and to crack cutter, substantially can retain the raw material of bamboo chip, fracture bamboo reinforcement hardly.

The technical solution of the utility model is:

A kind of bamboo chip cracks cutter, and comprising: columniform cutter hub, its center offers the hole of trough of belt, it is characterized in that, the buck knife circumferentially offering many row's Heterogeneous Permutations of cutter hub, adjacent buck knife is provided with the room suitable with buck knife position.

By arranging room, can guarantee that bamboo chip combines as a whole.

During side-looking, between described two adjacent buck knifes, form V-shaped.If there is no space during side-looking between adjacent two buck knifes, consequently, easily make bamboo reinforcement injured, serious, also can fracture bamboo reinforcement, we know, the bamboo chip main object of cutter of cracking is cracked, and when cracking, do not wish that digging out bamboo silk forms gap, but extrude gap by extruding, therefore, during extruding, bamboo reinforcement can occur to bend phenomenon, in this case, bamboo reinforcement between adjacent two buck knifes of dislocation has twice bending superposition phenomenon, obviously, the more long bamboo reinforcement that more can not fracture of this bending segment, between two buck knifes that the utility model is adjacent, side-looking forms V-shaped is exactly to extend bending segment, bamboo reinforcement elasticity near buck knife tooth crest is better, the distance of bamboo reinforcement bending segment can suitably shorten, bamboo reinforcement elasticity near buck knife tooth root portion is poor, the distance of bamboo reinforcement bending segment can proper extension, also just define side-looking between two buck knifes and form V-shaped.

The both sides of described buck knife have inclined-plane.Utilize this inclined-plane can reduce buck knife and the power needed for extruding is stitched to bamboo.

Head and the afterbody of described buck knife have the knife edge.It should be noted that, the processing cost of buck knife is very high, in prior art, usually only the knife edge is set at the head of buck knife, because, in extrusion process, only have its effect of the knife edge of the head of buck knife, the utility model, head and the afterbody of buck knife all arrange the knife edge, be when after the wearing and tearing of one of them knife edge, cutter removed, changes a direction, the head of buck knife and afterbody have changed position can also work as the use of new cutter, therefore, greatly reduce cost, improve the utilization rate of cutter.

One of preferably, the top of described buck knife has straight line, in the extrusion process of cutter to bamboo chip, when the angle of the knife edge is less, effect is better, obviously, when the top of buck knife has straight line, the top that the angle of the knife edge is less than buck knife has angle during circular arc line.

As preferably, the width D of described V-shaped is 3-6mm.

The invention also discloses a kind of bamboo chip to crack the processing method of cutter, comprise described a kind of bamboo chip and to crack cutter, it is characterized in that, process as follows:

The cutter hub of A, processing column shape, its center offers the hole of trough of belt;

B, the equally spaced circumferential slot of cylindrical upper processing, form the inclined-plane of buck knife both sides;

C, cylindrical upper processing axial groove, form the V-shaped between two adjacent buck knifes;

D, dislocation cut out buck knife, reserve the room suitable with buck knife position;

Head and the afterbody of E, processing buck knife form the knife edge;

F, the circular arc line at buck knife top is processed into straight line.

The utility model has rational in infrastructure, cost is lower, bamboo chip cracks good, the not easily broken bamboo of quality, extends the beneficial effect of cutter life.

Detailed description of the invention

Now by reference to the accompanying drawings the utility model is further described:

As shown in the figure, a kind of bamboo chip cracks cutter, and comprising: columniform cutter hub 1, its center offers the hole 2 of trough of belt, and the buck knife 3 circumferentially offering many row's Heterogeneous Permutations of cutter hub 1, adjacent buck knife 3 is provided with the room 5 suitable with buck knife 3 position.

During side-looking, between two adjacent buck knifes 3, form V-shaped 4.

The both sides of buck knife 3 have inclined-plane 32.

The head of buck knife 3 and afterbody have the knife edge 31.

The top of buck knife 3 has straight line 30.

The width D of V-shaped 4 is 3-6mm.

When adjacent two buck knifes 3 pairs of bamboo reinforcements 7 misplaced extrude, there is twice bending superposition phenomenon, occurred bending segment 71.

Bamboo chip cracks the processing method of cutter, comprises described a kind of bamboo chip and to crack cutter, process as follows:

The cutter hub 1 of A, processing column shape, its center offers the hole 2 of trough of belt;

B, the equally spaced circumferential slot 6 of cylindrical upper processing, form the inclined-plane 32 of buck knife 3 both sides; Such as use lathe car circumferential slot 6, cutter has two inclined-planes.

C, cylindrical upper processing axial groove, form the V-shaped 4 between two adjacent buck knifes 3; Such as mill out V-shaped 4 with milling cutter;

D, dislocation cut out buck knife 3, reserve the room 5 suitable with buck knife 3 position; Room 5 is milled out with milling cutter;

E, the head processing buck knife 3 with milling cutter and afterbody form the knife edge 31;

F, with milling cutter or grinding machine, the circular arc line at buck knife 3 top is processed into straight line 30.

Completion of processing is heat-treated cutter.
