Abstract
The present invention relates to a kind of molds to assemble position precision holes processing method, includes the following steps：Assembling position roughing on die main body slightly first hole, will rough machined thick just hole aperture amplification manufacture, first hole after enlargement ratio is not less than 1.25 times of thick first bore dia；First hole after die main body and enlargement ratio is heat-treated；Plugging material is filled up in first hole, the hardness of the plugging material is less than the hardness of after heat treatment die main body material；It fills up to finish on plugging material after plugging material and makes precision holes.The present invention provides a kind of easy processing and protects precision, and the hole machined time is short, and drilling tool without abrasion, reduces manufacture cost and cost of labor, and fool proof substantially.
Description
Technical field
The present invention relates to the processing methods of precision holes, and in particular to a kind of mold assembles position precision holes processing method.
Background technology
Because of mold manufacturing mesoporous feature：1. polyisocyanate shape, 2. single and mini-batch production in irregular shape 3. required precision height 4. polygamy
Make 5. middle or small, deep 6. preferential processing.General hole machined one bores two expansions, three four borings of brill nothing but, is aided with assorted fixture, material hardness is high
With regard to using special cutter head.
There is higher hardness requirement in working position in mold manufacturing, considers its preferential processability, the processing of precision holes ordinary priority
In place, then carry out heat treatment ensure its hardness, but be heat-treated after precision holes generally have a little deformation, it is difficult to ensure its precision.And
When hardness requirement is not high at its pilot hole, original mould process is still processed in a traditional way, and final precision is difficult to ensure that, processing
Because of hardness height, cutter is easy to wear, and tipping, which is easy to cause, occurs accident, and some is even basic to process, and increases manufacture cost in hole
And cost of labor.
Invention content
To solve the above problems, the present invention, which provides a kind of easy processing, protects precision, the hole machined time is short, drilling tool substantially without
Abrasion reduces manufacture cost and cost of labor, and foolproof mold assembling position precision holes processing method.
Technical scheme of the present invention：
A kind of mold assembles position precision holes processing method, includes the following steps：
（1）Assembling position roughing on die main body slightly first hole, rough machined thick just hole aperture amplification is manufactured, is put
First hole after big multiplying power is not less than 1.25 times of thick just bore dia；
（2）First hole after die main body and enlargement ratio is heat-treated；
（3）By step（2）Plugging material is filled up at the beginning of treated in hole, the hardness of the plugging material is less than through step
（2）The hardness of rear mold material of main part is handled, the intensity of the plugging material meets the intensity requirement of assembling positioning；
（4）The first nose end mouth filled up after plugging material connects flat, finally with benchmark centering, finishes and makes on plugging material
Precision holes.Fine machining die subject type face keeps unity.
Further, the plugging material is mild steel Q235 or 20 steel.
Further, the method for filling up plugging material is filled up for pressure.
Further, the first hole after die main body and enlargement ratio be heat-treated to hardness in HRC38 ~ HRC62
Between.
Beneficial effects of the present invention：
Precision hole forming method using the present invention, plugging material hardness is low, and easy processing protects precision.The hole machined time is short,
Drilling tool without abrasion, reduces manufacture cost and cost of labor, and fool proof substantially.
The present invention is applied to pin position portion in the molds such as large quantities of molds, bending former, to ensure mold or so
Half model face consistency obtains significant effect in terms of saving the process-cycle and saving the cost of charp tool.
Specific embodiment
T8 steel mold bulk workpiece inoperatives part changing firmness requirements are not high, if finally will precision holes Φ 10H7 processed, according to biography
System mode first beats thick just hole Φ 10H7, and by roughing, slightly just hole Φ 10H7 apertures amplification, diameter are high-volume not less than 2.5mm, at this time
Hardness is relatively low easily to make.It then still provides for being heat-treated to required hardness requirement, after T8 steel quenches HRC58-62, first hole
It is lower than T8 steel hardness after quenching that easy processing material Q235, Q235 hardness is filled out in 13 H7 of Φ, finally with benchmark centering, with drill bit essence
Precision holes Φ 10H7 holes are made in processing, and finishing drum face keeps unity.
Precision holes Φ 10H7 are directly made after hole Φ 10 at the beginning of conventional method T8 steel roughing slightly, hardness, T8 are protected in reheating processing
Steel quenches HRC58-62, and so inevitably bore deformation precision reduces after heat treatment, can not meet requirement.It is first carried out if precision is protected
Heat treatment, T8 steel quenching HRC58-62, excessive high hardness after heat treatment, normal drill bit can not be processed at all, need to there is the old skilled worker of experience
It is processed with caution with special drill bit, is possible to success, consequently cost of labor and the cost of charp tool are excessively high.And easily crushing knife,
It causes danger.
Precision holes Φ 10H7 are beaten with the method for the present invention, precision holes Φ 1,0H7 100 processed scrap 2-3, drill bit.It makes a hole
Time 10min used, only more than ten yuan of the cost made a hole.Substantially reduce process time, the cost of charp tool.And safety is without danger
Danger, general apprentice can be competent at processing.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use the present invention.
A variety of modifications of these embodiments will be apparent for those skilled in the art, it is as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to and the principles and novel features disclosed herein phase one
The most wide range caused.
