Description
Technical field
The present invention relates to a kind of processing method for robotic part of embroidering, particularly single-needle embroidery robot threading hook for running stitch
Processing method.
Background technology
With the development of computer and automatic control technology, computer embroidering machine instead of traditional armstrong's patent embroidery
Machine, obtain more and more extensive application.Traditional computer embroidering machine is embroidered during embroidery using spininess, by needle exchange come
Colour changing, and the function of self-threading can not be realized, there is significant limitation in use.Especially in operating process
In, it is manually to introduce pin hole with hand to reach the standard grade, and operation inconvenience, is wasted time and energy, operating efficiency is very low.
At present, the threading mechanism on single-needle embroidery robot realizes an automatic thread-changing of threading a needle for more colo(u)r streaks, but
In the manufacture of threading hook for running stitch, it is contemplated that threading hook for running stitch needs to bear certain threading pulling force in threading process made of steel wire, because
This is, it is necessary to which the folding arm of threading hook for running stitch gib head is manufactured into outwards, and there is certain elevation angle and increase threading hook for running stitch section of steel wire size to carry
Its high tensile strength, therefore, the threading hook for running stitch produced is only applicable to No. 11 larger eedles of pin hole, can not be applied to pin hole
On less No. 9 eedles.And embroider line corresponding to large size eedle is thicker, the embroidery embroidered out is not exquisite enough, influences embroidery quality.
The content of the invention
It is an object of the invention to provide a kind of processing method of single-needle embroidery robot threading hook for running stitch, it is made up of this method
Thread threading hook for running stitch there is less gib head sectional dimension, stronger tensile capacity, can match somebody with somebody with No. 9 eedles of single-needle embroidery robot
Close and use, improve embroidery machining embroidery quality.
The present invention technical solution be：A kind of processing method of single-needle embroidery robot threading hook for running stitch, it is characterised in that
This method comprises the following steps that：
（1）, cold-drawn processing, select Special Steel Wire to be pulled, drawing machine is provided with 5-10 hot candied moulds, hot candied
Mould is set for staggered relative at a certain distance, and the hot candied hole on hot candied mould is relative with the hot candied hole of adjacent hot candied mould,
Steel wire passes through hot candied hole, and hot candied mould is rotated with 2500-3000 revs/min of rotating speed, and steel wire is passed through with 4-7 ms/min of speed
Cross hot candied mould；
（2）, threading hook for running stitch gib head shaping, the steel wire after cold-drawn is cut into chunks, steel wire section is sent to by folding by feed mechanism
Gib head shaping is carried out in bender, steel wire g. slice header is first rolled over into interior angle in 90 °, gib head is then bent into 12-16 ° of interior angle again, and
Gib head redundance is cut, threading hook for running stitch body is made；
（3）Threading hook for running stitch buckling is molded, and a diameter of 0.3mm circular threading hook for running stitch body is placed in punching machine mold and struck out
Type, the mm of threading hook for running stitch gib head global sections width≤0.28mm, height after shaping≤0.6；
（4）The heat treatment of threading hook for running stitch, manufactured threading hook for running stitch is heated up to 820-850 DEG C, is incubated 20-40 minutes, then
240-280 DEG C are quickly cooled to, the Rockwell hardness of threading hook for running stitch is reached 70-80HRC, and is incubated 3-5 hours, Rockwell hardness
Reach 45-55HRC, gib head vertical tension >=500 gram of threading hook for running stitch.
It is characteristic of the invention that：By threading hook for running stitch made of this method, its gib head sectional dimension is small, can be suitable for pin hole
No. 9 eedles of less embroidery robot use, while threading hook for running stitch gib head has a stronger tensile capacity, and its gib head vertical tension >=
500 grams, service life length.Threading hook for running stitch can be used cooperatively with No. 9 eedles of single-needle embroidery robot, greatly improve embroidery quality,
So that the application of single-needle embroidery robot is more extensive.
Brief description of the drawings
Fig. 1 is the schematic diagram of wire drawing process flow of the present invention；
Fig. 2 is the schematic diagram of threading hook for running stitch moulding process of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
Using the threading hook for running stitch be processed into of the present invention, available for No. 9 tambour needle self-threadings of embroidery robot, solve because
No. 9 tambour needle pin holes are small, and existing threading hook for running stitch gib head section is big, can not with No. 9 tambour needles it is supporting the problem of.In embroidery robot
Using No. 9 tambour needles, compared to No. 11 tambour needles, the embroidery quality of embroidery robot can be greatly promoted.
As shown in Figure 1, 2, select 82B models steel wire 3 to be pulled, 5-10 hot candied moulds can be provided with drawing machine, this
Embodiment sets 7 hot candied moulds 1, and hot candied mould is arranged on bearing 2 for staggered relative at a certain distance, and its end is provided with and pulled out
Silk hole, the hot candied hole on each hot candied mould is relative with the hot candied hole of adjacent hot candied mould, and steel wire passes through hot candied hole, hot candied mould with
Bearing is rotated with 2800 revs/min of rotating speed, can also be set in 2500-3000 revs/min, steel wire is with 5 ms/min of speed
Degree can also be set by the hot candied hole of hot candied mould in the range of 4-7 ms/min.By carrying out cold group to steel wire.
Steel wire after cold-drawn is cut into chunks, length is generally 2-3 rice, and steel wire section 5 is sent into bending by feed mechanism 4
In machine 6, the front end of steel wire section is located at slider of bender region, and by mould 10 and can move up and down sliding block 7 move up progress
Positioning, the length of mould 10 is the length of threading hook for running stitch, and the length can be set as requested.The front end of steel wire section processes hook
The part of head should exceed 1 centimeter or so of die length, be converted into steel wire g. slice header by moving up for sliding block 8 moving up and down
90 ° of interior angles, then using the linkage of bending linkage 11 and the bite 9 being obliquely installed, gib head is bent into from 90 ° of interior angles
15 ° of given bending angles of mould 10, bite are cut gib head redundance, and threading hook for running stitch body is made.Bending angle
It can also be 12-16 °.
According to the pinhole size of No. 9 tambour needles of embroidery robot, i.e. width 0.32mm, height 0.70mm will be a diameter of
One time punching molded, threading hook for running stitch gib head after shaping in the mould for the punch press that 0.3mm circular threading hook for running stitch body is placed on 5T stamping presses
The width of global sections is 0.28mm, is highly 0.6 mm, and can not be more than the size, ensures that threading hook for running stitch can pass through No. 9
Pin mouth.
In order to further improve the intensity of threading hook for running stitch, particularly hook head portions, manufactured threading hook for running stitch is heat-treated, added
Temperature is incubated 20-40 minutes, is then quickly cooled to 240-280 DEG C, the Rockwell hardness of threading hook for running stitch is reached to 820-850 DEG C
To 70-80HRC, 3-5 hours are incubated, the Rockwell hardness that threading hook for running stitch is made reaches 45-55HRC, and the gib head of the threading hook for running stitch is vertical
Pulling force is equal to or more than 500 grams.
