Description
Technical field
The present invention relates to a kind of cylinder components, more specifically, it relates to a kind of production technology of cylinder guide ring.
Background technique
Cylinder is the pneumatic products such as cylinder, pneumatic actuator with guide ring (also referred to as support ring, bracing ring, support ring etc.)
In a kind of common element.The effects of mainly playing interval between cylinder body inner piston, axis and cylinder barrel, positioning, avoid piston,
Axis and cylinder barrel metal directly rub, to cause the damage of mechanical structure.
Main manufacture currently on the market has: the direct lathe process of 1. plastic rods, and vehicle goes out guide ring, this mode
Obtained guiding ring size is more accurate, but serious waste material, while lathe process efficiency is slow, and the surface of product is crude；
2. being processed using mold injection, this guide ring shaping speed is fast, and manufacturing cost is low, but Product Precision is inadequate；3. being exactly first
It is molded by guide ring, then is finished with lathe, it is slow to will lead to efficiency in this way.Therefore the production method of existing guide ring is all deposited
The problem of production efficiency and precision cannot be taken into account.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of production work of cylinder guide ring
Skill has the effect of that production efficiency and precision are taken into account.
To realize the above-mentioned technical purpose, the present invention provides the following technical scheme that a kind of production work of cylinder guide ring
Skill, comprising the following steps:
Raw material are produced the profile of strip, width and thickness and the guide ring phase of profile by S1 by plastic extruder
Together；
S2, cutting continuous profile by cutting machine is one section one section, the length of every segment type material and the perimeter of guide ring
It is identical；
Every segment type material is individually positioned in fixture, makes shape bending at the shape of guide ring by S3；
Fixture is put into baking oven and is heated to certain temperature by S4, removes original stress of profile, and profile is default in fixture
Type；
Fixture is taken out out of baking oven, and is put into sink by S5；
S6 after fixture is cooled to room temperature, takes out fixture and isolates guide ring；
Guide ring is dried up and is examined by S7, and qualified guide ring is encapsulated and is put in storage.
By using above-mentioned technical proposal, in production equipment it is most of can the multiple guide rings of simultaneous processing, the same to time-division
It cuts machine and also only cuts this movement, also do not need later period shaping deburring, realize the raising of working efficiency.Plastic extrusion
The strip section surface that machine squeezes out is smooth, and burr and pit is not present, heats after being bent by fixture, can't make profile
Melt, therefore profile will not be adhered to chucking surface, fixture will not be made to wear, and ensure that the machining accuracy of guide ring,
Therefore above-mentioned production technology realizes while guaranteeing machining accuracy and production efficiency.The strip section squeezed out by plastic extruder,
Different from the injection molding of injection mold, guide ring is by fixture come brake forming, therefore will not occur to generate regrinding-material, simultaneously
Lathe process is not needed, does not generate waste material, while power cost reduces, every guide ring power consumption about 0.00575KW is realized yet
The reduction of production cost.
Preferably, the raw material in the S1 are polyformaldehyde.
By using above-mentioned technical proposal, polyformaldehyde material has good comprehensive performance, including mechanical property, heat-resisting
Property, wear resistance, chemical resistance and self-lubrication, and coefficient of friction is low, there is certain anti-flammability, it is easy to process, it can protect
It is smooth to demonstrate,prove the strip section surface processed.
Preferably, baking oven is heated to 130-260 DEG C in the S4.
By using above-mentioned technical proposal, guarantee that guide ring softens completely, but will not melt again, avoids leading-becoming to ring
Shape.After guide ring keeps curved form, the bending stress generated when curved guide ring before can fade away, final curved
Guide ring becomes the normal morphology of profile.
Preferably, the heating time of baking oven is 30-60min in the S4.
By using above-mentioned technical proposal, baking oven is preheating to after maximum temperature maintains a period of time again, guarantees guide ring
Stress bending is eliminated, while also avoiding guide ring heating time too long, leads to energy waste.
Preferably, the direction of motion shape angle at 45 ° of the cutter and profile of the cutting machine.
By using above-mentioned technical proposal, after cutter cuts off profile, the both ends of profile are the end angle for tilting 45 °, are increased
The serious forgiveness of guide ring avoids the scale error due to guide ring, causes profile that can not be formed by bending annulus.
Preferably, the sink opens up on the ground in the S5, the sink is directed toward being provided on one side for baking oven and leads
Xiang Po, the guiding slope are located in sink.
By using above-mentioned technical proposal, can be directly pushed into sink after transfer cart is taken out out of baking oven, in sink
Water by the heat absorption on fixture and guide ring, accelerate the cooling velocity of guide ring, improve production efficiency.Staff can
Transfer cart to be pushed into sink along guiding slope, when taking out transfer cart, transfer cart can also be pulled out along guiding slope, be improved
Operation convenience.
Preferably, offering circular groove, the diameter of the circular groove and the outer diameter phase of guide ring on the fixture in the S3
Together.
It by using above-mentioned technical proposal, will be placed in the circular groove on fixture after the shape bending cut, profile is certainly
Under the action of body bending stress, the inner sidewall of the lateral wall fitting circular groove of profile guarantees that the concentricity of profile complies with standard.
Preferably, being extended with cylindrical limited post, the gap width of the limited post and circular groove among the fixture
It is identical as the thickness of guide ring.
By using above-mentioned technical proposal, shape bending is at circular ring shape and is put into the gap between limited post and circular groove,
Since gap is identical with guiding ring-shaped, if the size of profile is not right, it just can not be put into gap, realize the sieve to profile
Choosing, waste material is taken out in advance, improves processing efficiency.Profile is limited column and circular groove clamping, and profile is avoided to generate due to bending
Bending stress and displacement, lead to the not formed guide ring of profile, improve machining accuracy.
In conclusion the present invention achieves following effect:
1. realizing the solid of guide ring by the cooperation of plastic extruder, cutting machine, baking oven and fixture, improving work
Make efficiency；
2. realizing the rapid cooling of guide ring by the cooperation of transfer cart and sink, improving work efficiency.
