The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.
The utility model provides a wear-resisting stranding mould of lightweight, as shown in fig. 1 to 9, includes mould body 1, is equipped with wear-resisting inside lining 2 in the mould body inner chamber, and is preferred, wear-resisting inside lining adopts high strength alloy inside lining, and the mould body adopts carbon fiber material to make, as the example, and the mould body adopts prepreg hot briquetting technology to make. The carbon fiber has the advantages of light weight, high strength, high temperature resistance, corrosion resistance and the like, the weight of the die is reduced, and the service life of the die is prolonged to the maximum extent by using the wear-resistant lining of the inner cavity of the die body.
The inner cavity of the die body comprises a taper hole structure 3 and a necking structure 4 at the front end of the taper hole structure; wear-resisting inside lining includes the close-up section 6 of taper section 5 and taper section front end, and the taper section corresponds the taper hole structure, and taper section outer wall and the cooperation of taper hole structure inner wall close-up structure, close-up section correspond the throat structure, close-up section outer wall and the cooperation of throat structure inner wall, wear-resisting inside lining and mould body combine firmly, and the cooperation is stable, smooth and smooth transition between taper section and the close-up section inner wall.
Be equipped with location structure between wear-resisting inside lining and mould body, guarantee that the mould combines stably between wear-resisting inside lining and mould body in the use, can not the drunkenness or shift, the finished cable quality is secure. Preferably, the wall thickness of the conical section is gradually increased from the end with the larger diameter to the end with the smaller diameter, so that the wear resistance of the position with the smaller inner diameter is effectively improved.
And the wall thickness of the closing-in section is greater than that of the cone-shaped section, namely, the wall thickness of the position with the minimum wall thickness of the closing-in section is greater than that of the position with the maximum wall thickness of the cone-shaped section. Because the abrasion loss of the closing-in section is larger than that of the conical section under the normal condition, the quality of the finished cable can be ensured not to be reduced even if the closing-in section or the conical section close to the closing-in section is slightly abraded after the mould is used for a long time, and the service life of the mould is prolonged. By way of example, the above mentioned wear-resistant lining has a thickness of between 2mm and 5mm, a minimum thickness of not less than 2mm and a maximum thickness of not more than 5mm.
In an alternative embodiment, the outer wall of the closing-in section is tapered 18, and the outer diameter of the closing-in section gradually decreases from the end connected with the tapered section to the end far away from the tapered section. Usually, the diameter of the maximum outer diameter part is 1-3mm larger than that of the minimum outer diameter part, and excessive taper is not needed, so that the structural design can prolong the service life of the wear-resistant lining and is beneficial to stable matching of the wear-resistant lining and the inner cavity of the die body.
Usually, the positioning structure is arranged on the outer wall of the wear-resistant lining, and a groove structure matched with the positioning structure is arranged on the die body.
In an alternative embodiment, as shown in fig. 1 to 4, the die body is of a unitary structure, and the positioning structure includes a flange 7 outward of the large diameter end of the wear-resistant lining, and preferably, the flange and the wear-resistant lining are integrally formed. A plurality of connecting holes 14 are arranged on the flanging, and are generally uniformly distributed by taking the axis of the wear-resistant lining as the center. The groove structure comprises a positioning groove 8 which is arranged on the outer end face of the die body (on one side of the taper hole structure) and matched with the flanging, a plurality of fixing holes are formed in the bottom face 9 of the groove, and the wear-resistant lining and the die body are fixed by screwing a connecting piece 15 penetrating through the connecting hole in each fixing hole.
In another alternative embodiment, the mold body is a split structure, and includes a first mold half 10 and a second mold half 11, which are assembled together to form an inner cavity for accommodating the wear-resistant lining. By way of example, the specific structure may be designed as: an arc-shaped groove is formed in one side, facing the second half mould, of the first half mould, and first half mould side wings 12 are arranged on two sides of the first half mould respectively; the second half mould has the same structure as the first half mould, one side of the second half mould, which faces the first half mould, is also provided with an arc-shaped groove, two sides of the second half mould are also provided with second half mould side wings 13, and the first half mould side wings and the corresponding second half mould side wings are fixed by bolts. As shown in fig. 5, after the first half-mold flank and the second half-mold flank are connected and fixed by using bolts, an inner cavity for accommodating the wear-resistant lining is formed between the two half molds, and at the moment, the wear-resistant lining with the flanging is installed in the inner cavity.
As a further improvement to the above solution, the positioning structure may not adopt the above matching form of the turned-over edge and the positioning groove, as shown in fig. 6 to 8, the specific structure may be designed to provide a positioning ring 16 in the middle of the outer wall of the wear-resistant inner side, and preferably, the positioning ring and the wear-resistant lining are integrally formed. The groove structure comprises a positioning ring groove 17 which is arranged on the inner wall of the arc-shaped groove of the first half die and the inner wall of the arc-shaped groove of the second half die and is matched with the positioning ring. When the structure is designed, the second half die and the first half die are buckled and fixed, the wear-resistant lining can be clamped and fixed in the inner cavity, the positioning ring of the wear-resistant lining is embedded in the positioning ring grooves of the two half dies, as shown in figures 7 to 9, even a flanging is not required to be designed at the tail end of the wear-resistant lining, and then the connection and fixation are not required to be carried out by utilizing a connecting piece, so that the stability of the wear-resistant lining can be kept.
The die provided by the invention adopts a mode of combining the wear-resistant lining and the die body, the inner wall of the wear-resistant lining is used as a working surface for cabling operation, only the inner surface of the wear-resistant lining needs to be finished, the structural and dimensional limitations of the die body are less, the processing precision requirement of the die body is low, the wear-resistant lining is made of high-strength alloy, and the service life is long.
The wear-resisting inside lining is equipped with binding off section one side external diameter by taper section one side and increases gradually, can guarantee that wear-resisting inside lining has more permanent life, during the production different products, only need to change assorted wear-resisting inside lining can, the commonality is good, and when wear-resisting inside lining reached life, only need change wear-resisting inside lining, and need not whole change mould, use cost is also lower.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
