Description
Technical field
The utility model relates to a kind of Surface heat-treatent molds, cover carbon mould more particularly to a kind of synchronous ring of gear box
Tool.
Background technique
Synchronous ring of gear box surface friction material is huge on synchronizer performance influence, is surface-treated to synchronous ring
When, frequently with carbon technique is covered, carbon material is adhered to synchronous ring surface, obtains that thickness is suitable, bonding firmly covers carbon-coating.Together
When, also to guarantee that product circularity, angle, cone depth equidimension cover the good of carbon technique within the scope of product requirement after covering carbon
The bad height for directly influencing product quality.And synchronize ring and cover carbon die in covering carbon technique, product size after covering carbon is played
Critical effect.
It is current to cover carbon technique referring to Fig. 1 for outer tooth ring, mainly carbon item is hot-pressed onto together at high temperature by upper mold 1
It walks on ring 2, controls product by adjusting block 3 and bore depth.But due to current die form and structure, in the fabrication process,
Technological datum is different from product benchmark or measuring basis, and (current process benchmark is in synchronous ring small end face, product or measuring basis one
As in large end face), cause bore depth directly influenced by supplied materials size fluctuation, required process capability, therefore product is not achieved
Using 100% detection mode.
Utility model content
The utility model is exactly to solve the above-mentioned problems, to overcome the problems of in the prior art, the utility model
A kind of synchronous ring is provided and covers carbon die with meet demand.
To achieve the goals above, the technical solution of the utility model is as follows:
A kind of synchronous ring covers carbon die, including upper die and lower die, and the upper surface of the lower die is provided with for placing synchronization
The fixing groove of ring, the lower section of the upper mold are taper, which is characterized in that are provided with a circle on the top outer circumference surface of the upper mold
The outer circumference surface of step, the upper mold is additionally provided with baffle ring outside, and the top surface of the baffle ring is stuck at step, and the bottom surface of baffle ring is stuck in
The top surface of synchronous ring.
A kind of above-mentioned synchronous ring covers carbon die, which is characterized in that is additionally provided on the outer circumference surface of the bottom of the baffle ring
One circle groove, further includes fine tuning retaining ring, and the fine tuning retaining ring is arranged in the groove.
A kind of above-mentioned synchronous ring covers carbon die, which is characterized in that by being detachably connected between the baffle ring and upper mold.
A kind of above-mentioned synchronous ring covers carbon die, which is characterized in that is provided in correspondence with each other in the baffle ring and upper mold
Bolt hole, and baffle ring and upper mold are bolted.
A kind of above-mentioned synchronous ring covers carbon die, which is characterized in that the height of the baffle ring is less than the height of upper mold.
The beneficial effects of the utility model are: 1, product cone depth can control in sufficiently stable range, will greatly subtract
It does over again caused by conelet depth；2, cone depth is not influenced by supplied materials size, does not need to manually adjust gasket intervention cone depth；3, it mentions
High process capability, existing 100% detection mode can be changed to frequency sampling observation, labor hour needed for reducing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the prior art covers carbon mould；
Fig. 2 is the structural schematic diagram of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to Fig. 2, a kind of synchronous ring covers carbon die, including upper mold 100 and lower die 200, the upper surface of lower die 200 are provided with
For placing the fixing groove 210 of synchronous ring 300, the lower section of upper mold 200 is taper, when work, the lower section taper of upper mold 200
Carbon item is hot-pressed at high temperature on the inner surface of synchronous ring.But due to current die form and structure, in the fabrication process,
Technological datum is different from product benchmark or measuring basis, current process benchmark in synchronous ring small end face (i.e. lower end surface), product or
Measuring basis generally in large end face (i.e. upper surface), causes cone depth directly to be influenced by supplied materials size fluctuation, needed for being not achieved
Process capability.
Therefore it is provided with a circle step 110 on the top outer circumference surface of upper mold 100, is gone back outside the outer circumference surface of upper mold 100
It is provided with baffle ring 400, the top surface of baffle ring 400 is stuck at step 110, and the bottom surface of baffle ring 400 is stuck in the top surface of synchronous ring 300.By
In there is baffle ring 400 to be stuck between upper mold 100 and the upper surface of synchronous ring 300, thus by technological datum by product small end face change to
Large end face is overlapped technological datum with product benchmark or measuring basis.When supplied materials size fluctuates, cone depth is nor affected on
Control.
In order to further control cone depth, is increasing outside baffle ring 400, also set on the outer circumference surface of the bottom of baffle ring 400
It is equipped with a circle groove 410, further includes fine tuning retaining ring, fine tuning retaining ring is set in groove 410, can further adjust baffle ring
400 height, to control cone depth.
By being detachably connected between baffle ring 400 and upper mold 100, in one of preferred embodiment of the utility model
In, bolt hole in correspondence with each other is provided on baffle ring 400 and upper mold 100, and baffle ring 400 and upper mold 100 are connected by bolt
It connects.
The height of baffle ring 400 is less than the height of upper mold 100, and upper mold 100 is protruded into synchronous ring 300 and carries out covering carbon.
The beneficial effects of the utility model are: 1, product cone depth can control in sufficiently stable range, will greatly subtract
It does over again caused by conelet depth；2, cone depth is not influenced by supplied materials size, does not need to manually adjust gasket intervention cone depth；3, it mentions
High process capability, existing 100% detection mode can be changed to frequency sampling observation, labor hour needed for reducing.
