Description

A cutter that is used for titanium sponge titanium to stick together cutting

Technical Field

The utility model belongs to the technical field of a non ferrous metal smelting equipment, concretely relates to cutter that is used for titanium sponge titanium to stick together the cutting.

Background

The titanium sponge is produced by the reduction reaction of refined magnesium and titanium tetrachloride, and the byproduct magnesium chloride is produced at the same time, the magnesium chloride is electrolyzed again to produce refined magnesium and chlorine, the chlorine reacts with titanium-rich ore to produce titanium tetrachloride, and the refined magnesium and the titanium tetrachloride are used for producing the titanium sponge, thereby forming a closed cycle. The reduction reaction of refined magnesium and titanium tetrachloride is carried out in a reaction kettle, the distilled titanium sponge is in a shape of a cylinder with a cap, the titanium lump is called as a titanium lump, the titanium lump needs to be crushed into titanium blocks with the granularity of 0.83-25.4 mm, the whole titanium lump cannot be crushed integrally due to large volume, the titanium lump needs to be cut into a proper size, then the titanium lump is crushed by a crusher, and finally the finished titanium sponge is packaged into a barrel.

A large-scale oil press is used for cutting the titanium lump, a special cutter is installed on the large-scale oil press, the cutting edge of the cutter is in a linear shape, is connected with an oil press body through a through hole bolt, and is straight and free of protrusions. In the cutting process, the cutter back of a knife hugs closely titanium and sticks together, easily cause the pollution, can appear connecting not hard up, simultaneously because of cavernosum intensity is high, toughness is good, easily glue the sword, the titanium piece size is big after once cutting, it accounts for about 55% to be greater than 300mm titanium piece, can't satisfy breaker pan feeding dimensional requirement, need carry out the secondary cutting, can cause the hydraulic press once cutting shaping rate low, cutter life is short, the cutting size is great, and breaker load of use is big, the fault rate is high and breaker knife tooth life short scheduling problem.

SUMMERY OF THE UTILITY MODEL

The utility model discloses titanium sponge titanium to present the general adoption stick together cutting equipment's weak point, design a cutter, solve the cutting pollution, connect easily not hard up, once cut the shaping rate low, life is short, the big problem of cutting back material piece size.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the utility model provides a cutter that is used for titanium sponge titanium to stick together cutting, includes back of a knife blade and cutting edge, and the back of a knife blade is equipped with the bolt hole, the cutting edge is sawtooth sword and the double-deck cutting edge of sharp sword alternate arrangement to the straight line sword is at upper and sawtooth sword under, the front of sawtooth sword is parallel with the front of the back of a knife blade, and the back of sawtooth sword is the inclined plane, the thickness of cutting edge root is greater than the thickness of the back of a knife blade, forms the boss openly at the cutting edge.

The thickness of boss is for being greater than 0, and be less than 50 mm.

The length of the straight edge is less than 600 mm.

The distance between adjacent sawtooth edges is 30-60 mm.

The staggered tooth depth between the tip of the sawtooth edge and the straight edge is less than 100 mm.

The tip of the sawtooth blade is of an arc structure, and the radius of the arc is 1-10 mm.

The included angle between the bevel edge on any side of the sawtooth edge and the straight line edge is 90-180 degrees.

The bolt holes are counter bores.

A cockscomb structure cutter for titanium sponge titanium sticks together cutting, there are following advantages in titanium sponge titanium sticks together cutting process:

1. the one-time cutting forming rate is high, the requirement of the crusher on the feeding size can be met only by one-time cutting, and the forming rate of the one-time cutting titanium block smaller than 300mm is more than 95 percent and is 2 times of that of the existing linear cutter;

2. the cutting efficiency is high, the service life is long, and is 2 times of that of the existing linear cutter;

3. the cutter is firmly connected with the oil press and is not easy to loosen, and the cutter back of the cutter is not tightly attached to the titanium lump and does not cause pollution;

4. the titanium blocks generated during cutting are small and uniform in size, the load of the crusher is reduced, and the service life of the cutter teeth of the crusher is prolonged.

Detailed Description

The technical solution and use of the present invention will be further explained by the following detailed description with reference to the accompanying drawings.

As shown in the figure, the cutter body comprises a cutter back and a cutter edge 2, wherein a plurality of rows of counter bore bolt holes 1 are formed in the cutter back, the cutter edge 2 comprises a plurality of sawtooth blades 4 and a plurality of linear blades 5, the sawtooth blades 4 and the linear blades 5 are sequentially and alternately arranged in the blade length direction of the cutter edge 2, and the positions of the linear blades 5 on the cutter body are higher than those of the sawtooth blades 4, so that an upper layer of blades and a lower layer of blades can be formed, the upper layer of blades are composed of the plurality of linear blades 5, and the lower layer of blades are composed of the plurality of sawtooth blades 4; the blade length L1 of the straight blade 5 is 0-600 mm, the tip distance L2 of adjacent sawtooth blades 4 is 30-600 mm, and the staggered tooth depth L3 between the tips of the sawtooth blades 4 and the straight blade 5 is 0-100 mm; the included angle theta between the bevel edge on any side of the serrated edge 4 and the straight line edge 5 is 90-180 degrees, the tip of the serrated edge 4 is of an arc structure, the radius R of the arc is 1-10 mm, and the phenomenon that the blade 2 is cracked or broken due to the concentrated acting force during cutting is avoided. The front of serrated edge 4 is parallel with the front of the back of the knife blade, and the back of serrated edge 4 is the inclined plane, the thickness of 2 roots of cutting edge is greater than the thickness of the back of the knife blade, forms boss 3 in 2 fronts of cutting edge, the thickness L4 of boss 3 is 0~50mm, the front mean when the cutter body cuts titanium sponge, towards the one side of titanium sponge, the opposite side is the back, during the cutting, the cutter begins the cutting (as shown in the figure) from the terminal surface that titanium sponge sticks together 7, 2 fronts of cutting edge directly contact with titanium sponge, and because the existence of boss 3, the front of the back of the knife blade does not contact with titanium sponge to avoid causing the pollution to titanium sponge.

When using, install cutter 8's the back of a knife blade on hydraulic press 6, among the prior art, when cutter 8 adopted the through-hole with being connected of the 6 bodies of hydraulic press, on average use 2 months and need fasten once, and adopt the utility model discloses a during counter bore connection, can increase the resistance of the vertical direction of cutting, the connection that can avoid producing after long-time work is not hard up, improves cutter application safety factor, and on average use 6 months needs fasten once.

During the cutting, sawtooth sword 4 contacts earlier with titanium lump 7, carries out the first cutting, and straight line sword 5 contacts with titanium lump 7 afterwards again, carries out the secondary cutting.

The utility model provides a cutter 8 and among the prior art straight line cutter cut 20 titanium respectively and stick together and contrast, and finally straight line cutter cutting back, the average weight of titanium piece that the size is < 300mm is 475Kg, accounts for and compares 47.5%, and the utility model discloses a cutter 8 cutting back, the average weight of titanium piece that the size is < 300mm is 956Kg, accounts for and compares 95.6%, and is visible the utility model discloses a cutter 8 improves more than the twice for the cutting shaping rate of the straight line cutter among the prior art.
