Description
Technical field
The invention belongs to field of machining, it 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 is 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 lot is big, 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.
The content of the invention
For the problem existed when overcoming tiny cutter heat treatment clamping, the present invention provides a kind of cutter heat treatment exclusive clamps
Tool, heat treatment process is carried out using quenching auxiliary clamp to cutter.
The technical scheme is that：
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 in batches complete many
The heat-treatment quenching of individual cutter.
Described hook is located at cutter Special fixture for heat treatment middle part, and hook bottom is fixed in lower plate through upper plate, uses
In mobile cutter Special fixture for heat treatment.Connected by four pillars between described upper plate and lower plate, 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 for cutting edge, subtract
The flexural deformation of small cutter, it is ensured 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 are according to tool length determination, 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 determination, specially：D=tool diameters+1mm, D are 5~13mm of Φ；D=tool diameters -1mm.
Application method of the invention is：By the blade of cutter down, it is put into plywood hole vertically, puts neat.It is quenched
, at clamping 1 upper end hook ring of hook, smoothly be put into fixture in salt bath furnace by Cheng Zhong, until blade (hardness be 63HRC~
66HRC) be totally immersed into saline solution and start to calculate soaking time, may finally disposable thermal processing go out multiple cutters, with hole
Quantity determine how many cutter can be put, such that it is able to accomplish the completion Quenching Treatment of batch.
The beneficial effects of the invention are as follows：The present invention ensure that every cutter is all placed vertically downward, effectively reduce knife
The flexural deformation of tool, it is ensured that the parallel immersed in liquid level of all cutting edges, it is ensured that cutter hardness is consistent, and can be on fixture simultaneously
50~100 cutters are placed, processing efficiency is greatly improved, it is ensured that product quality.
Brief description of the drawings
Fig. 1 is using cutter structure figure of the invention；
Fig. 2 is cutter Special fixture for heat treatment structure chart of the present invention；
In figure：1 hook, 2 upper plates, 3 iron wires, 4 pillars, 5 lower plates, 6 reinforcements.
Specific embodiment
With common No. 20 carbon steels as raw material, the structure of Fig. 2 is processed into, fixture is made up of six parts：If hook 1, upper plate 2,
3, four pillars 4 of dry iron wire, 5, two reinforcements 6 of lower plate.50~100 diameter D are uniformly distributed on upper plate 2 for 5~Φ of Φ 13
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 are corresponded in lower plate 5,
Notice that lower plate 5 is not through hole, d=knife part diameter -1mm prevent cutter from dropping, for thin wire winds several weeks at pillar 4, prevent
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
