Description

Technical Field

[0001] The present application relates to the technical field of reduced diameter outlet guide structures, and specifically discloses a high-speed wire reduced diameter outlet guide structure. Background Art

[0002] In the production process of wire used in steel rolling technology, it is necessary to roll on the rolling mill. The guides installed before and after the roll hole can help the rolled piece to enter and exit the roll forming accurately and stably in a predetermined direction and state.

[0003] In the prior art, guide structures are used at the inlets and outlets of all rollers, and their function is to enable the rolled piece to enter and exit the die in a desired state, thereby ensuring that the rolled piece is rolled according to predetermined deformation conditions.

[0004] However, in the process of wire diameter reduction, the traditional guide structure is not applicable. Figure 1 As shown, the traditional guide structure includes a guide splint and a mounting seat for installing the guide splint, wherein the guide splint is an integrally formed structure, and a nose tip is formed at its right end, and the inner side of the nose tip has the same diameter as the guide hole, extends in a straight line and is a smooth section.

[0005] During the diameter reducing operation, the sliding of the diameter reducing outlet may cause the top outlet and steel accumulation at the top outlet. The steel accumulation at the top outlet may cause damage to the nose tip of the traditional guide structure, and further cause damage to the entire guide splint, resulting in additional cost consumption.

[0006] Therefore, in view of this, the inventor provides a high-speed wire diameter reducing outlet guide structure to solve the above-mentioned problem. Utility Model Content

[0007] The utility model aims to solve the problem that in the process of reducing the diameter of wire rods, the nose tip of the guide splint of the traditional guide structure is easily damaged, resulting in loss of the overall structure and additional increase in cost.

[0008] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a high-speed wire reducing outlet guide structure, including a catheter, a guide box body which is sleeved outside the catheter and used to fix the catheter, and a nose tip arranged at the end of the catheter, wherein the nose tip is detachably connected to the catheter, and the nose tip includes a connecting portion detachably connected to the catheter and a plurality of guide plates circumferentially fixed to the free end of the connecting portion, the guide plates enclose a chamber which is connected to the inner cavity of the catheter and is used to guide the wire, and the outer walls of the free ends of the guide plates are inclined toward the ends to form a conical surface.

[0009] Furthermore, it also includes a fixed dovetail fixedly connected to the bottom of the guide box body.

[0010] Furthermore, the guide box body and the catheter are connected and fixed by using nuts.

[0011] Furthermore, the connecting portion and the free end of the catheter are connected and fixed by a nut.

[0012] Furthermore, the inner side surface of the free end of the guide plate is provided with an inclined surface inwardly, and a smooth transition is adopted between the inclined surface and the remaining inner side surface of the guide plate.

[0013] Furthermore, the guide plates are distributed in a rectangular shape at the free ends of the connecting portion, and gaps are formed between the free ends of adjacent guide plates.

[0014] Furthermore, a transition surface is formed between the inclined surface and the conical surface at the free end of the guide plate.

[0015] The principle and effect of this scheme are:

[0016] Compared with the prior art, the utility model adopts a combination of a detachable catheter and a nose tip to form a detachable guide structure. When the nose tip needs to be replaced due to long-term use or is damaged, the nose tip can be disassembled and replaced separately without replacing the catheter and the guide box body, thereby reducing the cost of use. The nose tip is used as a consumable spare part, and the catheter and the guide box body are used as fixed spare parts, thereby solving the problem that the nose tip of the guide splint is easily damaged during the diameter reduction operation of the traditional guide structure, resulting in loss of the overall structure and additional cost consumption.

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] The reference numerals in the drawings of the specification include: a guide splint 1, a traditional nose tip 2, a catheter 3, a connecting portion 4, a guide box body 5, a guide plate 6, a fixed dovetail 7, a slope 8, and a transition surface 9.

[0024] A high-speed wire rod reducing outlet guide structure, for example Figure 2 , Figure 3 and Figure 4 As shown:

[0025] The invention comprises a catheter 3, a guide box 5 which is coaxially installed outside the catheter 3 and used for fixing the catheter 3, and a nose tip installed at the end of the catheter 3.

[0026] A through hole is provided on the guide box body 5 for the catheter 3 to pass through. Two first threaded holes are also provided on the top of the guide box body 5 and are respectively connected to the through holes. By screwing a nut inward, the bottom of the nut can be pressed against the catheter 3 installed in the through hole, thereby fastening the catheter 3 to prevent it from loosening during the production process.

[0027] The two ends of the catheter 3 extend out of the guide box 5 respectively, and the nose tip is installed at the left end of the catheter 3 in a detachable connection manner. The nose tip includes a connecting portion 4 and four guide plates 6 integrally formed circumferentially at the left end of the connecting portion 4. The guide plates 6 enclose a chamber that is connected to the inner cavity of the catheter 3 and is used to guide the wire. In this embodiment, the inner diameter of the chamber is larger than the inner diameter of the catheter 3, and the outer wall of the left end of the guide plate 6 is inclined toward the end to form a conical surface. The connecting portion 4 is wrapped around the outer side of the left end of the catheter 3, and the outer wall of the catheter 3 fits the inner wall of the connecting portion 4. A second threaded hole is opened on the connecting portion 4. By screwing the nut inward, the bottom of the nut can be pressed against the outer wall of the left end of the catheter 3. In this way, the connecting portion 4 and even the nose tip are fastened to the catheter 3 as a whole to prevent the nose tip from loosening.

[0028] In this embodiment, a fixed dovetail 7 is integrally formed at the bottom of the guide box body 5 .

[0029] Moreover, a section of inclined surface 8 is formed inwardly on the inner side surface of the left end of the guide plate 6, and a smooth transition is adopted between the inclined surface 8 and the remaining section of the inner side surface of the guide plate 6.

[0030] Furthermore, the four guide plates 6 are specifically distributed in a rectangular shape at the left end of the connecting portion 4 . The four guide plates 6 are respectively located at four sides of the rectangle, and gaps are formed between the left ends of adjacent guide plates 6 .

[0031] Moreover, a transition surface 9 is formed between the inclined surface 8 and the conical surface at the left end of the guide plate 6. By adopting a smooth transition and setting the transition surface 9, it is more convenient for the wire to enter and pass.

[0032] When the utility model is used, the guide box body 5 is first installed on the existing guide base, and then the fixed dovetail 7 is matched with the existing base dovetail and fixed by a nut;

[0033] Then, insert the catheter 3 into the guide box 5 and fix it with a nut, and then fix the nose tip with the nut and use it;

[0034] The guide structure is composed of the catheter 3, the guide box 5 and the nose tip. When the nose tip is worn out due to long-term use or damaged during use, the nose tip can be replaced separately to reduce cost investment;

[0035] Moreover, compared with the integrally formed guide splint 1 and the traditional nose tip 2 in the prior art, in this embodiment, the consumption of the reduced-diameter exit guide plate is greatly reduced, and the rolling tonnage is reduced from about 600 tons per pair to 5,500 tons per pair. The failure time and scrap rolling indicators achieve zero impact and zero steel pile for the whole month, and can be repaired and reused to save costs, greatly reduce the labor intensity of employees, and ensure safety. This implementation has tangible efficiency improvement, with a wire rod output of 120t / h, which can save 4 hours per month for production. Calculated based on 10 months of production per year, 40 hours can be saved throughout the year. Calculated based on 600 yuan / profit per ton of steel, the efficiency improvement is 120t / h*40h*600 yuan / t=2.88 million, so it has strong practicality.

[0036] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
