Description
Technical field
The present invention relates to machinery fields, particularly relate to a kind of compression method of single knitting machine support integral die-cast.
Background technology
In order to ensure the dynamics of bearing of single knitting machine support, in the market common stent be made of ironwork,
It is very heavy, bring great inconvenience to carrying and storage；And its production method is by upper support plate and the welding of lower support plate
At the both ends of supporting rod, appearance can clearly see Welding Problems, and due to the high mild oxidation of welding and mixing for impurity
Enter either not prison welding etc. to cause weld bond nearby the strength of materials declines or the defects of snap, knitting machine fast turn-around or
When larger pressure is born in person's long-time service, the phenomenon that easily fracture；And its processing program very complicated, manufacture not only take
When, and it is of high cost.
Threaded hole on knitting machine support in the market in support plate and lower support plate is all unified specification, standard specification
For 95mm and 100mm, therefore user is when in use, it is necessary to first know the screw hole specification could replaceable holder well, it is no
It will cause diversified in specifications, the problem of can not installing, and manufacturing firm is in the stent for producing different size, not only will basis
Screw hole specification is different and outputs two molds, and the stent for the different size produced will also be separated and be stored, and needs very
Big warehouse area is used to store.
Invention content
The present invention proposes a kind of single knitting machine support and its compression method of integral die-cast, solves single in the prior art
Face knitting machine rack screw hole is diversified in specifications and brings storage is inconvenient, replaces the problem of inconvenient, while also avoid traditional weldering
The problem of endurance caused by connecing technique declines and weldering schlieren rings beauty etc..
The technical proposal of the invention is realized in this way：
A kind of single knitting machine support, it is characterized in that, support plate is opened up there are two symmetrical groove profile through-hole.
Further, the groove profile through-hole is in ellipticity, and into step in the groove profile through-hole.

Further, the distance of the groove profile through-hole and the sliding slot exterior point of groove profile through-hole is less than or equal to 95mm.
Further, support plate includes upper support plate and lower support plate.
Further, the upper support plate and lower support plate use the method die casting of integral die-cast at the both ends of supporting rod.
Further, the supporting rod is a hollow siphunculus.
Further, a through-hole is offered on the tube wall of the supporting rod.
Further, a tooth hole is offered on the tube wall of the supporting rod.
The present invention also provides a kind of compression methods of single knitting machine support integral die-cast, include the following steps：
The present invention also provides a kind of compression methods of single knitting machine support integral die-cast, it is characterised in that：The present invention
Grinding tool fill aluminium alloy liquid simultaneously using both ends, the both ends are upper support plate feed end and the charging of lower support plate respectively
End, each feed end are designed using double feed inlet, in favor of improving the flowing velocity of liquid and reducing the decline of temperature, and import
Reach Synchronous lifting supporting rod temperature against supporting rod, high temperature aluminium alloys liquid wash makes the surface of supporting rod make its raising, reaches
Effective combination of support plate and supporting rod after to cooling and solidifying improves support plate and the conjugation of supporting rod welding, molten in this way
The effect connect be so that supporting rod and support plate are not forced and the two separation or fracture, intensity reaches 900 kilograms or more.
According to the more than description of this invention it is found that compared with prior art, the invention has the advantages that：
1. since the upper support plate and lower support plate are respectively opened up there are two symmetrical groove profile through-hole, the groove profile leads to
Hole is in ellipticity, by walking of the screw in elliptoid sliding slot, is adapted to the size of different size.
2. preferably, the groove profile through-hole is less than or equal to 95mm, mating hole and hole with point distance in the slideway of groove profile through-hole
Distance be 95mm two screws fastening.The groove profile through-hole is more than or equal to point distance in the slideway of groove profile through-hole
100mm can be adapted for fastening of the distance in mating hole and hole for two screws of 100mm.
3. present invention die casting stent by way of aluminium alloy water integral die-cast, while the weight of I-shaped foot can be mitigated
Intensity caused by avoiding conventional bonding technique declines and weldering schlieren rings the defects of beautiful.
4. the compression method of aluminium alloy water integrated die-casting stent provided by the invention simplifies the production technology of stent, improve
Production efficiency.
5. structure design of the present invention is ingenious in the extreme, technological process is very convenient, has very big use value.
Description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, to embodiment or will show below

Method, including upper support plate 1, supporting rod 2 and lower support plate 3, the upper support plate 1 and lower support plate 3 are using integral die-cast
Method welding is respectively opened up and is led to there are two symmetrical groove profile in the both ends of supporting rod 2, the upper support plate 1 and lower support plate 3
Hole 5, since the screw hole of market upper bracket and the spacing unified specification of screw hole are 95mm or two kinds of 100mm, producer is in life
The mold of plurality of specifications is had to out during production, the cost of die sinking is very high, and the product produced also must pile up separately, it is no
Then easily obscure taking and placing inconvenience, and the stent storage of plurality of specifications needs very big plant area, increase producer into
This, therefore the groove profile through-hole 5 is designed to step 51 by the present invention, so that fastened by screw is in the taking of axis.The groove profile leads to
Hole 5 and the minor axis length of groove profile through-hole 5 are not less than 95mm, and the long axis length of the groove profile through-hole 5 and groove profile through-hole 5 is not less than
100mm, to be applicable in the screw of different size.Due to the rack screw hole on jersey machine and the specification of the distance of screw hole
95mm and 100mm are fixed as, therefore, the length of the short axle is set as 95mm, the length of the long axis is set as 100mm.The branch
Strut 2 is a hollow siphunculus, and for conducting wire or other accessories of shuttling, 4 He of a through-hole is offered on the tube wall of the supporting rod 2
An at least tooth hole 41.
It, only need to be interior according to reality in groove profile through-hole 5 to screw when the stent diameter difference on the jersey machine of user
Demand moves in or out the combination demand to be suitble to jersey machine, and such setting can be saved greatly
Producer produces the cost of stent, and it is also very local in terms of the storage of stent just and save very big space, to factory
Family saves a very big cost.
It is preferred that：The total length of stent is 490mm ± 0.1, and 2 length 488mm of supporting rod supports side surface inside from one
The through-hole 4 of a 25mm is offered at 120mm and the tooth hole 41 of a 5mm, upper branch are offered at another support plate inside 145mm
Support plate 1 or lower support plate 3 are all provided with there are two groove profile through-hole 5, the diameter 9mm of the through-hole, and step 51 is added in groove profile through-hole 5,
The stepped counterbore 14.5mm, deep 9mm, the thickness 20mm of the support plate, length 129mm, unify support plate two
Slideway exterior point distance between groove profile through-hole 5 is greater than or equal to 100mm, and interior point distance is less equal than 90mm, to realize screw
It can slide between slideway exterior point and interior point, assembled conducive to the fastening of the different model with jersey machine.
