Abstract

The invention discloses a combined conveniently-detached tool for a multi-jaw waste material breaker. The combined conveniently-detached tool for the multi-jaw waste material breaker comprises a rotary tool rest, cutters, bent cutters and colliding cutters; the rotary tool rest is formed by machining a tool rest and a spacer bush integrally; each bent cutter and the corresponding cutter are movably connected to form an assembly; the colliding cutter and the corresponding cutter are movably connected to form another assembly; and 2-4 cutter assemblies with the bent cutters and 2-4 cutter assemblies with the colliding cutters are respectively movably connected with the rotary tool rests through the cutters, and are uniformly distributed along the peripheral direction of the rotary tool rest. The tool provided by the invention is simple to mount and detach, convenient to replace, and short in maintenance time, and improves the using efficiency of a breaker; a tool with expressive price can be repaired and then is recycled, and the using cost is lowered; and the combined conveniently-detached tool can operate through the connection of a key slot in the rotary tool rest and a main shaft of the breaker by a flat key, a long hexagon or long spline shape which is required to be machined for the main shaft of the common breaker is avoided, and the manufacturing cost of the breaker is lowered.

Description

Combination detachable cutter for a kind of multijaw waste material disintegrating machine

Technical field

The present invention relates to the cutter using on a kind of disintegrating machine, relate in particular to a kind of combination detachable cutter of the multijaw waste material disintegrating machine for broken scrap metal.

Background technology

The cutter using for the disintegrating machine of broken scrap metal is a kind of consumable accessory, because wearing and tearing, tipping, impact and be damaged, also be to affect the key factor that disintegrating machine uses, it is to form through the manufacture of special thermal treatment technique with alloy tool steel that cutter generally all makes, expensive, also cause the manufacture of disintegrating machine and use cost high.At present both at home and abroad the cutter of waste material disintegrating machine is that rotary knife base is made to two assemblies that separate of tool rest and spacer, then by cutting knife, plastic cutter, hit cutter and be fixed on tool rest by the mode of welding.The cutter of this structure has following shortcoming: (1), by being welded and fixed cutter, the high temperature producing when welding can cause localized tempering, reduces tool surface hardness, has affected cutter result of use; (2) mode that can only cut by flame after tool damage is dismantled, and has so not only destroyed cutter, has also destroyed the conjunction plane of tool rest, causes that maintenance time is long, maintenance cost is high; (3) cutter of pulling down, because be damaged and can not repair use, has been wasted resource; Also increased cost.(4) use this cutter crusher axis will be processed to growth hexagon or long spline-shaped, processing cost is high, manufacturing process is complicated, to material require high.

Summary of the invention

Technical problem to be solved by this invention is the defect that overcomes prior art, provides a kind of and installs and removes convenience, can repair the combination detachable cutter using.

Combination detachable cutter for multijaw waste material disintegrating machine of the present invention, comprises rotary knife base, cutting knife, plastic cutter, hits cutter; Described rotary knife base is that tool rest and spacer are processed into one, and described plastic cutter is flexibly connected into assembly with cutting knife; The described cutter that hits is flexibly connected into assembly with cutting knife; 2-4 the cutter assembly with plastic cutter and 2-4 are flexibly connected with rotary knife base by cutting knife respectively with the cutter assembly that hits cutter, and circumferentially uniform along rotary knife base.

Described plastic cutter is flexibly connected into assembly with cutting knife, is to have bolt hole on plastic cutter and cutting knife, connects fastening by hexagon socket countersunk flat cap head screw.

The described cutter that hits is flexibly connected into assembly with cutting knife; Be to hit cutter and cutting knife has bolt hole, connect fastening by hexagon socket countersunk flat cap head screw.

Described flexible connection with rotary knife base by cutting knife is to have draw-in groove on rotary knife base and cutting knife, the draw-in groove on cutting knife with draw-in groove clamping on rotary knife base, again connect with hexagon socket countersunk flat cap head screw fastening.

To combine detachable tool assembly complete after, the keyway by rotary knife base connects with the main shaft of disintegrating machine with flat key.

Advantage of the present invention:

(1) cutter mounting or dismounting are simple, replacing is convenient, and maintenance time is short, has improved disintegrating machine service efficiency; (2) expensive cutter can be repaired, reuse, and greatly reduces use cost; (3) because combination detachable cutter can be connected and carry out work with the main shaft of disintegrating machine with flat key by the keyway on rotary knife base, avoid the long hexagon that common crusher axis need to process or grown spline-shaped, also reduce the manufacturing cost of disintegrating machine.

Detailed description of the invention

Rotary knife base 1 is that tool rest 7 and spacer 6 are processed into one; On plastic cutter 3 and cutting knife 2, have bolt hole 11, be connected into assembly with soket head cap screw 5;

Have bolt hole 11 hitting on cutter 4 and cutting knife 2, be connected into assembly with soket head cap screw 5;

On rotary knife base 1, have and on draw-in groove 8, draw-in groove 9 and cutting knife 2, have draw-in groove 10 and bolt hole 11;

Cutter assembly by 2-4 with plastic cutter, and 2-4 with hit cuttercutter assembly is respectively by draw-in groove 8 and draw-in groove 9 clampings on draw-in groove 10 and rotary knife base on cutting knife; And circumferentially uniform along rotary knife base; Connect fastening with soket head cap screw 5 again;

To combine detachable tool assembly complete after, connect with the main shaft of disintegrating machine by the keyway 12 use flat keys on rotary knife base.

Above embodiment is only in order to illustrate the present invention and unrestricted technical scheme described in the invention; But those skilled in the art should be appreciated that still and can modify or be equal to replacement the present invention; And all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, it all should be encompassed among claim scope of the present invention.
