Description
Technical field
The invention belongs to machinery manufacturing technology field, more particularly to a kind of engine timing system transmission dynamic rail model machine are quick
Manufacturing process.
Background technology
When preparing engine timing system transmission dynamic rail model machine, classical production process can cause product in process
In, due to factors such as material stresses, cause deformation of products, it is impossible to meet the size of model machine and the processing request of structure, and do not have
Systematic manufacturing process, wastes time and energy.
The content of the invention
Timing system is driven dynamic rail model machine quick manufacturing process.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of engine timing system is driven dynamic rail model machine quick manufacturing process, comprises the following steps：
Step 1, blank：Whole PA66HI plastic plate is cut into small pieces material, the length of the cobbing and wide longer than product
With it is wide unilateral big 2 millimeters -3 millimeters, the thickness of its thickness ratio product is thick 8 millimeters -10 millimeters, because finished product length and cross direction deformation
Small, Deformation in thickness is big, so made allowance, thickness direction are tried one's best more made allowances less as far as possible for sawing sheet size length and cross direction；
Step 2, fly face：Material unnecessary on the cobbing thickness, the two sides excision of the cobbing are cut off with disc knife
Amount is every 2 millimeters -3 millimeters of face, and material two sides resection is equal, if unequal, finished product will be to resection greatly one
Face is bent, and thickness is unilateral reserved 1 millimeter -1.5 millimeters, and the cutting output of Z-direction is 0.2 millimeter -0.3 millimeter, and cutting output is excessive, into
Product are easily deformed；
Step 3, material heat treatment：Step 2 is flown in the cobbing heated-air circulation roaster 3 hours behind face by normal
Temperature is heated to 100 degree, then 160 degree were heated in 4 hours, 160 degree of holding temperature 3 hours, then with 20 degree per hour of speed
Degree is cooled to 40 degree, is then taken out from heated-air circulation roaster, room temperature -4 hours 2 hours；
Step 4, roughing：The cobbing after being heat-treated to step 3 carries out obverse and reverse roughing, more than processing
Measure to be unilateral reserved 1 millimeter；
Step 5, front finishing：The surplus of first processing X direction and Y-direction, the surplus of Z-direction are finally processed, to reduce
The deformation of thickness direction, filled after the completion of the finishing of front with gypsum, to reduce the shake knife of reverse side finishing and stress deformation；
Step 6, reverse side finishing：The gypsum filled is scraped smooth after the completion of front is finished, and makes gypsum less than product just
The benchmark of the peak in face, reverse side processing significant dimensions and size, after front machines, product has more or less a small amount of
The benchmark of deformation, significant dimensions and size causes dimension overproof in positive handling ease；
Step 7, cleaning：With clear water cleaning product, the gypsum of filling is removed, cleaned up；
Step 8, side finishing：The tool of a side processing is first done using an actor's rendering of an operatic tune of product reverse side as positioning, is passed through
Change the angle of tool, process other 3 sides successively；
Step 9, by hand processing：The flash remained on product is handled totally by hand.
Further, in the step 1, the profile extruded direction of length direction and plastic plate of the cobbing keeps one
Cause, whole PA66HI plastic plate is that thermoplastic shaping extrusion comes out, and stress deformation can be reduced along extrusion direction blank.
Further, in the step 4, first converted products center section, the peripheral portion of last converted products.
Further, in the step 4, after the completion of roughing, semi-finished product are placed -16 hours 12 hours at normal temperatures, with
Releasable material stress.
Compared with prior art, the beneficial effects of the invention are as follows：A kind of engine timing system transmission dynamic rail of the present invention
Model machine quick manufacturing process, reduce the product structure brought by factors such as material stresses and deform, method is simple to operation, finished product
Size, structure etc. meet making and required.
Embodiment
In view of the defects of above-mentioned prior art is present, it is an object of the invention to provide just combine to implement below a kind of engine
Example, the embodiment of the present invention is described in further detail, so that technical solution of the present invention is more readily understood, grasped, but
The invention is not limited in this.Experimental method described in following embodiments, it is conventional method unless otherwise specified；The examination
Agent and material, unless otherwise specified, commercially obtain.
Embodiment：
A kind of engine timing system transmission dynamic rail model machine quick manufacturing process of the present embodiment, comprises the following steps：
Step 1, blank：Whole PA66HI plastic plate is cut into small pieces material, the length of cobbing and wide longer and wide than product
Unilateral big 2 millimeters -3 millimeters, the thickness of its thickness ratio product is thick 8 millimeters -10 millimeters, because finished product length and cross direction deformation are small,
Deformation in thickness is big, so made allowance, thickness direction are tried one's best more made allowances less as far as possible for sawing sheet size length and cross direction；
Step 2, fly face：With material unnecessary on disc knife excision cobbing thickness, the two sides resection of cobbing is every
2 millimeters -3 millimeters of face, material two sides resection is equal, if unequal, finished product will be bent to the big one side of resection, thick
Unilateral reserved 1 millimeter -1.5 millimeters are spent, the cutting output of Z-direction is 0.2 millimeter -0.3 millimeter, and cutting output is excessive, and finished product easily becomes
Shape；
Step 3, material heat treatment：Step 2 is flown to the cobbing heated-air circulation roaster behind face by normal temperature to be added in 3 hours
Heat is to 100 degree, then 160 degree were heated in 4 hours, 160 degree of holding temperature 3 hours, then cold with 20 degree per hour of speed
But to 40 degree, then taken out from heated-air circulation roaster, room temperature -4 hours 2 hours；
Step 4, roughing：Cobbing after being heat-treated to step 3 carries out obverse and reverse roughing, and allowance is
It is unilateral reserved 1 millimeter；
Step 5, front finishing：The surplus of first processing X direction and Y-direction, the surplus of Z-direction are finally processed, to reduce
