Description
Technical field
The utility model relates to sewing mechanical equipment technical field, refers in particular to a kind of needle plate of double needle lockstitch machine.
Background technology
The needle plate of Sewing machines is important parts in Sewing machines, and needle plate has the rotating shuttle positioning boss for fixing High Rotation Speed, rotating shuttle positioning boss utilizes its straight trough mouth to fix the fixed part of rotating shuttle particularly; In the course of the work, the fixed part of rotating shuttle can to straight trough mouth generation impact back and forth.At present, the needle plate of the market overwhelming majority is all formed by casting, its toughness and anti-wear ability relatively poor, when being used to the clothing making thick material, the straight trough mouth of rotating shuttle positioning boss is more prone to damaged, and in daily production, the straight trough mouth of some needle plate only uses fortnight just to damage, straight trough mouth is scrapped once the damaged monoblock needle plate that just causes, therefore waste is serious, and service life is short, and part replacement frequently causes cost of equipment maintenance high.
Utility model content
The utility model provides a kind of needle plate of double needle lockstitch machine for the problem of prior art, and its rotating shuttle positioning boss has extraordinary anti-wear performance, and not fragile, long service life, effectively reduces cost of equipment maintenance.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of needle plate of double needle lockstitch machine, comprise needle plate main body, described needle plate main body is arranged at intervals with two feed dog notches, the front of needle plate main body is provided with needle plate tooth, protrude respectively in the relative both sides at the back side of needle plate main body and be formed with rotating shuttle positioning boss, described rotating shuttle positioning boss is provided with rotating shuttle locating notch, and the arranged outside of described rotating shuttle positioning boss has reinforced sheet, and described reinforced sheet is provided with the breach suitable with rotating shuttle locating notch.
Wherein, the outside of described rotating shuttle positioning boss is provided with the holddown groove with the outline adaptation of reinforced sheet, and described reinforced sheet is fixedly welded in holddown groove.
Wherein, described rotating shuttle positioning boss is provided with the inserting groove for fixing reinforced sheet, and described reinforced sheet interference is plugged in inserting groove.
Preferably, described reinforced sheet is rectangular-shaped carbide alloy steel disc.
Wherein, the outer surface of described rotating shuttle positioning boss is coated with hard chrome coating.
The beneficial effects of the utility model:
The needle plate of a kind of double needle lockstitch machine that the utility model provides, the arranged outside of its rotating shuttle positioning boss has reinforced sheet, and reinforced sheet is provided with the breach suitable with rotating shuttle locating notch.Rotating shuttle positioning boss and reinforced sheet combine by the utility model, make rotating shuttle locating notch have extraordinary anti-wear performance, and in use not fragile, long service life, effectively reduces cost of equipment maintenance.

Detailed description of the invention
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that embodiment is mentioned is not to restriction of the present utility model.See Fig. 1 to Fig. 3, below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1 and Figure 2, the needle plate of a kind of double needle lockstitch machine that the present embodiment provides, comprise needle plate main body 1, described needle plate main body 1 is arranged at intervals with two feed dog notches 2, the front of needle plate main body 1 is provided with needle plate tooth 3, protrude respectively in the relative both sides at the back side of needle plate main body 1 and be formed with rotating shuttle positioning boss 4, described rotating shuttle positioning boss 4 is provided with rotating shuttle locating notch 5, the arranged outside of described rotating shuttle positioning boss 4 has reinforced sheet 6, and described reinforced sheet 6 is provided with the breach 7 suitable with rotating shuttle locating notch 5.In the present embodiment, the outside of described rotating shuttle positioning boss 4 is provided with the holddown groove (not marking in the drawings) with the outline adaptation of reinforced sheet 6, and described reinforced sheet 6 is fixedly welded in holddown groove.Preferably, described reinforced sheet 6 is rectangular-shaped carbide alloy steel disc.
Due to carbide alloy have that hardness is high, wear-resisting, intensity and a series of premium properties such as toughness is better, heat-resisting, corrosion-resistant, particularly its high rigidity and ABRASION RESISTANCE, even if also substantially remain unchanged at the temperature of 500 DEG C, 1000 DEG C time, still have very high hardness.In the present embodiment the reinforced sheet 6 for carbide alloy steel disc is fixedly welded on the outside of rotating shuttle positioning boss 4, reinforced sheet 6 and rotating shuttle positioning boss 4 are combined, so in the course of the work, first the fixed part of rotating shuttle can act on reinforced sheet 6 to the impact that straight trough mouth produces back and forth, but there is extraordinary anti-wear performance for the reinforced sheet 6 of carbide alloy steel disc, in use not fragile, only have reinforced sheet 6 be worn after just progressively can affect the long service life of monoblock needle plate, find after overtesting, service life after reinforced sheet 6 is combined with rotating shuttle positioning boss 4 is 10 times of original life-span, the time cycle changing needle plate is long, effective reduction cost of equipment maintenance.
As shown in Figure 3, as another embodiment, described rotating shuttle positioning boss 4 is provided with the inserting groove for fixing reinforced sheet 6, and the interference of described reinforced sheet 6 is plugged in inserting groove.The centre position of the rotating shuttle positioning boss 4 that described inserting groove is arranged on, and the thickness of inserting groove size and reinforced sheet 6 is adaptive, needle plate of the present utility model before use, first reinforced sheet 6 interference is plugged in inserting groove by use instrument, reinforced sheet 6 strengthens its hardness, intensity and toughness in the middle of rotating shuttle positioning boss 4, make needle plate possess the effect of embodiment one equally, be in use not easy wearing and tearing.The difference of the present embodiment and embodiment one is, does not need seam-welding equipment to fix reinforced sheet 6, only iron hammer need be used to knock the centre that reinforced sheet 6 can be fixed on rotating shuttle positioning boss 4, simply easy for installation.
Wherein, the outer surface of described rotating shuttle positioning boss 4 is coated with hard chrome coating (not marking at figure).Rotating shuttle positioning boss 4 is on the basis increasing reinforced sheet 6, again local Hard Chromium Coating is carried out to itself, Hard Chromium Coating can strengthen hardness and the ABRASION RESISTANCE of rotating shuttle positioning boss 4 on the whole, and make rotating shuttle positioning boss 4 possess better anti-wear performance, not fragile, service life more lengthens.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
