Description
Technical field
The utility model belongs to field of machining, is related to a kind of cutter Special fixture for heat treatment.
Background technology
At present, the cutter such as high-speed reamer, reamer, drill bit, slotting cutter, blade hardness are 63HRC~66HRC, shank
Hardness is 33HRC~48HRC, it is necessary to, immerse salt bath furnace in heat treatment process is carried out to above-mentioned cutter by cutting edge down
In, heating and thermal insulation quenching is carried out, to reach the hardness requirement of blade.
Because tool dimension is tiny, production is of large quantities, and how effective clamping turns into greatest difficulty in quenching process, if
Deal with improperly, the serious waste time in clamping process, can not only influence quenching hardness and hardness range, and influence quenching effect
Rate, so as to influence product quality.
Utility model content
In order to overcome the problem of existing during tiny cutter heat treatment clamping, it is special that the utility model provides a kind of cutter heat treatment
With fixture, heat treatment process is carried out to cutter using quenching auxiliary clamp.
The technical solution of the utility model is：
A kind of cutter Special fixture for heat treatment, including hook, upper plate, iron wire, pillar, lower plate, reinforcement, hook, upper plate,
By being welded to connect between lower plate, pillar, reinforcement, cutter Special fixture for heat treatment material is carbon steel, can be completed in batches more
The heat-treatment quenching of individual cutter.
Described hook is located in the middle part of cutter Special fixture for heat treatment, and hook bottom is fixed in lower plate through upper plate, is used
In mobile cutter Special fixture for heat treatment.Connected between described upper plate and lower plate by four pillars, on upper plate and lower plate
50~100 holes of even distribution, the quantity in hole and position correspond on upper plate and lower plate, are inserted perpendicularly into, subtract for cutting edge
The flexural deformation of small cutter, ensure that cutter hardness is consistent.Described iron wire is wound in four pillar peripheries, for prevent cutter from
Drop fixture side.Described reinforcement is welded in cutter Special fixture for heat treatment bottom.
Upper plate and lower plate vertical range H determine according to tool length, H=tool lengths -10mm.The hole of upper plate is through hole,
A diameter of D of through hole；End closure under the hole of lower plate, hole upper end diameter is d, for preventing cutter from dropping；D is according to the actual chi of cutter
Very little adjustment determines, is specially：D=tool diameters+1mm, D are 5~13mm of Φ；D=tool diameters -1mm.
Application method of the present utility model is：By the blade of cutter down, it is put into plywood hole, puts neat vertically.Quench
During fire, at clamping 1 upper end hook ring of hook, smoothly fixture is put into salt bath furnace, until blade (hardness be 63HRC~
66HRC) be totally immersed into saline solution start calculate soaking time, may finally disposable thermal processing go out multiple cutters, with hole
Quantity determine how many cutter can be put, so as to accomplish the completion Quenching Treatment of batch.
The beneficial effects of the utility model are：The utility model can ensure that every cutter is all placed vertically downward, effectively
Reduction cutter flexural deformation, ensure the parallel immersed in liquid level of all cutting edges, ensure that cutter hardness is consistent, and fixture
On can place 50~100 cutters simultaneously, greatly improve processing efficiency, ensure product quality.
Brief description of the drawings
Fig. 1 is to apply cutter structure figure of the present utility model；
Fig. 2 is the utility model cutter Special fixture for heat treatment structure chart；
In figure：1 hook, 2 upper plates, 3 iron wires, 4 pillars, 5 lower plates, 6 reinforcements.
Embodiment
Using common No. 20 carbon steels as raw material, Fig. 2 structure is processed into, fixture is made up of six parts：If hook 1, upper plate 2,
5, two dry 3, four pillars 4 of iron wire, lower plate reinforcements 6.It is 5~Φ of Φ 13 that 50~100 diameter D are uniformly distributed on upper plate 2
Hole, D can be processed according to the diameter of cutter, D=knife part diameters+1mm；The vertical range H of upper plate 2 and lower plate 5
It is processed according to tool length, H=knife part length -10mm.The number of locations in hole and upper plate 2 correspond in lower plate 5,
It is not through hole to pay attention to lower plate 5, d=knife part diameter -1mm, prevents cutter from dropping, and several weeks are wound for thin wire at pillar 4, is prevented
Only cutter drops from side.Hook 1, upper plate 2, lower plate 3, pillar 4, reinforcement 6 are by being welded to connect.
Claims (1)
1. a kind of cutter Special fixture for heat treatment, it is characterised in that the cutter Special fixture for heat treatment material is carbon steel, can be criticized
Amount completes the heat-treatment quenching of multiple cutters, including hook, upper plate, iron wire, pillar, lower plate, reinforcement, hook, upper and lower plates, branch
Pass through the company of welding between post, reinforcement；
Hook is in the middle part of cutter Special fixture for heat treatment, and hook bottom is fixed in lower plate through upper plate, for moving cutter
