A base for a guide support frame for the front passage of pinch rolls in a high-speed wire rod mill

Abstract

This utility model discloses a support frame base for a front guide for the pinch rolls of a high-speed wire rod mill, comprising a base plate, a connecting plate, and a top plate. By providing limiting devices on two support frames, the front guide column can be fixed by controlling the studs. Combined with the operation of the control screw, the fixing block secures the front guide column. This multi-faceted fixation ensures a robust fixation of the front guide column. Various inner diameter front guides can be designed according to the specifications of the rolled products, while maintaining a consistent shape. This ensures that the same support frame base can accommodate the installation and positioning of front guides and support frames with different inner diameters. It also solves the problem of non-standard distances between the pinch rolls and the cooling guide grooves in the water tank. Furthermore, the structure is simple and easy to assemble and disassemble, thereby reducing replacement and disassembly time, increasing production line operating rate, and reducing the workload of operators.

Description

Technical Field

[0001] This utility model relates to the field of high-speed wire rod production technology in the metallurgical industry, specifically to a base for a guide support frame for the front empty passage of the pinch rolls in a high-speed wire rod rolling mill. Background Technology

[0002] High-speed wire rod mill production lines are currently the main type of machines used in high-speed wire rod production in China. Their main production process includes billet feeding, heating, roughing, intermediate rolling, pre-finishing, finishing, water cooling, wire drawing, Stellmore air cooling line, coiling, P / F line, trimming, packaging, weighing, uncoiling, and warehousing. When producing large-size products, high-speed wire rod mills face challenges due to the large size of the rolled pieces, low production speed, and difficulty in forming coils.

[0003] The main function of the pinch rolls is to clamp the rolled piece along its entire length by rotating the pinch roll ring counterclockwise, providing a certain clamping force and forward thrust to help the rolled piece form a coil smoothly. When producing small-sized products, due to the small size of the rolled piece and the high rolling speed, especially when the tail of the coil leaves the finishing mill, the rear of the rolled piece is in a free state, which can easily lead to tail-wagging and tangling problems. By clamping the tail of the rolled piece with the pinch roll ring, and ensuring that the linear speed of the pinch roll ring is less than the speed of the coiler, the rolled piece is kept in a slightly pulled state between the pinch rolls and the coiler, avoiding steel piling accidents and ensuring normal coiling. After the pinch roll position is designed, there is a certain distance between it and the water tank cooling guide groove, requiring the design and use of a free guide and its support device. Since the specifications of the water tank cooling guide groove are fixed, it is generally designed in two sizes. When the workpiece needs to change its running direction at the pinch roll position, especially in the production of small-gauge wire rod, the rolling speed is basically 100m / s-120m / s. The inner diameter of the pinch roll inlet and outlet guides and the size of the workpiece should not differ too much. Otherwise, the workpiece will vibrate within a large range, which can easily lead to steel piling accidents. According to the product outline, the pinch roll inlet and outlet guides are generally designed with 5-6 models. Therefore, this utility model provides a high-speed wire rod mill pinch roll front guide support frame base to solve the above problems. Utility Model Content

[0027] Bolt holes are provided on both sides of the base 1, and bolts are installed and fixed in the bolt holes on both sides of the base 1.

[0028] The inner end of the limiting device 6 contacts the empty guide column 8.

[0031] The two connecting plates 102 are arranged in a figure-eight structure.

[0032] Working principle:

[0033] 1. Based on the maximum specifications of the rolled product and the distance between the pinch roll and the cooling guide groove of the water tank, the external dimensions of the idle guide support frame base should be reasonably designed.

[0034] 2. To ensure the uniformity of the base of the guide support frame, the external dimensions of the guide and the support frame are all of the same model. The inner diameter of the guide is designed in 5 different models according to the product specifications.

[0035] 3. To facilitate quick assembly and disassembly of the idle guide, the idle guide is assembled inside the support frame and positioned by the support frame. The idle guide is secured by pins and wedge blocks. The support frame is installed and positioned on the base using fixing bolts.

[0036] 4. To improve the positioning accuracy of the air-passing guide and prevent it from moving during use, a protrusion structure is designed at the front end of the air-passing guide. The protrusion locks the support frame, which can effectively prevent the air-passing guide from moving.

[0037] 5. To prevent the head of the rolled piece from impacting the guide and causing steel buildup, the front end of the guide is designed with a flared opening structure, which facilitates the smooth entry of the rolled piece into the guide.

[0038] 6. Design the outer dimensions of the guide frame base for the empty feed roller based on the dimensions of the guide and support frame, while also considering the height of the rolling line.

[0039] 7. The upper part of the base of the guide support frame is a connecting and fixing plate, which is mainly used to install and fix the guide support frame by bolt connection.

[0040] 8. The bottom of the guide support frame base is designed with a fixed base plate. The base plate has four bolt holes, which are mainly used to connect with the precast bolts of the foundation through the bolt holes.

[0041] 9. To ensure the strength and wear resistance of the guide support frame base, the material of the guide support frame base is generally selected to be wear-resistant and high-temperature resistant alloy cast steel, so as to ensure that it will not deform or break under increased impact load.

[0042] 10. The specific dimensions of the guide support frame base can be designed and selected according to the needs of the guide and support frame on site.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
