Problems solved by technology

However, further experiments and research have shown that the lower pins made of supporting mounting parts and supporting lower apron running parts are prone to fall off, and the combination of the two is not firm, which affects the quality of spinning; and the use of plastics such as nylon or carbon fiber The lower pin made of material, the processing process is complicated, the surface roughness of the casting process is poor, it is difficult to ensure the uniformity of the product
Due to the difference in material and processing technology of the lower pin, the surface roughness of the lower pin will seriously affect the spinning quality (Cv%), and the difference between the spindles (Cvb) is very large; therefore, a new structure and new material of the spinning frame is redesigned Downselling has become a top priority

Embodiment 1

[0045] A combined spinning frame ceramic lower pin, such as figure 1 As shown, the ceramic lower pin includes a support mounting part 1 and a supporting lower apron running part 2, wherein the ceramic lower pin also includes a connecting fastening for connecting the supporting mounting part 1 and the supporting lower apron running part 2 together. piece 3;

[0046] Such as figure 2 As shown, the support mounting part 1 is integrally formed by a self-locking installation slope part 11, a self-positioning bevel part 12 and a free end part 13; Angle trapezoidal face same side notched angle waist constitutes self-locking installation inclined plane 14; The random section of described self-positioning bevel part 12 is the right-angled trapezoidal face of identical shape, described right-angled trapezoidal face same side oblique waist constitutes self-positioning beveled face 15 ; The waist of the self-locking installation slope 14 forms a σ angle of 91° with the top; the slope w...

Embodiment 2

[0051] A combined spinning frame ceramic lower pin, such as Figure 6 and Figure 7 As mentioned above, the ceramic lower pin is different from Example 1 in that the material supporting the lower apron running part 2 is clay ceramics; Figure 8 As shown, the top of the support mounting part 1 is provided with a tapered positioning groove 16; as Figure 9 As shown, the inner side of the top of the connecting fastener 3 is provided with a positioning conical protrusion 32 matched with the tapered positioning groove 16; the bottom side of the connecting fastener 3 is provided with a clip 33; the clip 33 can be stuck in the On the self-positioning bevel part 12; the snap feet 33 have elasticity; and the waist of the self-locking installation bevel 14 forms a σ angle of 95° with the top; the slant waist of the self-positioning bevel surface 15 forms a β angle of 75° with the top; connection The fastener 3 is made of elastic steel with a certain thickness.

Embodiment 3

[0053] A combined ceramic lower pin for spinning frame. The difference between the ceramic lower pin and Example 2 is that the support mounting part 1 is cold-drawn flat steel, the size of which is 420×3.5×20 mm, and the material is 45# steel; The shape of any cross-section of the lower apron running part 2 is the same, and the upper surface of the cross-section is a combined shape of a section of straight line and a section of curve. The length of the part is 5mm; the length of a curved part connected with a straight part is correspondingly 19mm, and the distance A1 between the highest point and the leading edge of a straight part is 10.23mm; the distance between the highest point and the tail end of the lower pin of the rubber ring The distance C1 is 13.77 mm; the height difference H1 between a curved part and a straight part is 3.3 mm; the total height H2 of the section is 5-26.25 mm; the total width is 20 mm; The through groove 21 has a depth of 13.6 mm and a width L3 of 3...

Abstract

The invention relates to a combined type ceramic lower rubber ring pin of a spinning machine. The ceramic lower rubber ring pin comprises a supporting installation part and a bearing lower rubber ring operating part, wherein the ceramic lower rubber ring pin further comprises a connecting fastener which is used for connecting the supporting installation part with the bearing lower rubber ring operating part together. The combined type ceramic lower rubber ring pin of the spinning machine disclosed by the invention is very convenient to mount and dismount; moreover, the connecting fastener is arranged between the supporting installation part and the bearing lower rubber ring operating part so as to firmly and stably combine the supporting installation part with the bearing lower rubber ring operating part; meanwhile, the technical problems that the conventional combined type lower rubber ring pin is infirm in combined installation and the spinning quality is affected by mechanical waves produced in a spinning process are overcome.

Description

technical field [0001] The invention relates to a lower pin, in particular to a ceramic lower pin of a combined spinning frame. Background technique [0002] The spinning frame has become one of the indispensable machines in people's life; the lower apron pin supporting the lower apron used in the drafting mechanism of the ring spinning frame at home and abroad, referred to as the lower pin, is the drafting device. One of the main components in the yarn, it directly acts on the holding and drafting of the fiber strands, and plays an important role in controlling the movement of the fibers, so it has a great impact on the quality of the yarn. However, the existing bottom pins are basically formed by cold drawing. During the processing, due to the influence of machining precision, the precision of the bottom pins is reduced and the spinning quality is affected. At the same time, the processing by electroplating seriously affects the environment. [0003] The applicant disclos...
