Description

Technical Field

[0001] This utility model relates to the field of high-speed wire processing technology, and in particular to a high-speed wire hydraulic roller loading tool. Background Technology

[0002] Because the roll ring is located between the mill's cooling water pipes on the left and right sides, and between the inlet and outlet guides on the front and back sides, the installation space is extremely limited, leaving no suitable starting position and making it easy for the operator's hands to be bumped or crushed. Installing the tapered sleeve and roll ring onto the mill is difficult due to the limited space. Furthermore, when assembling the roll ring and tapered sleeve assembly onto the roll shaft, the flat end on the tapered sleeve must be aligned with the flat shoulder on the shaft for it to be inserted. The operator must support the weight of the roll ring and tapered sleeve and rotate the tapered sleeve to align it with the flat shoulder. The already confined space makes alignment difficult, and during alignment, the important working surface of the tapered sleeve is frequently bumped, causing damage.

[0003] High-speed wire rod production causes faster wear on the roller rings, so the replacement and installation of roller rings are carried out almost daily. The production line uses a total of eight such roller rings on a rolling mill with heavy roller rings. Therefore, for high-efficiency high-speed wire rod production, it is very important to facilitate the quick installation and replacement of the roller ring and tapered sleeve assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a high-speed hydraulic roller loading tool, which is designed to facilitate the quick and convenient replacement and installation of the roller ring and cone sleeve assembly.

[0005] To achieve the above objectives, this utility model provides a high-speed hydraulic roller loading tool, including a roller ring, a tapered sleeve inside the roller ring, and a locking mechanism;

[0006] The locking mechanism includes a first semi-circular ring, a second semi-circular ring, a first horizontal plate, a second horizontal plate, a lifting frame, a connecting screw, a locking nut, a reinforcing plate, and a limiting device. The first semi-circular ring and the second semi-circular ring can be slidably locked into the grooves of the roller ring. The first horizontal plate is welded to the first semi-circular ring, and the second horizontal plate is welded to the second semi-circular ring. The lifting frame is welded to the top of the first horizontal plate and the second horizontal plate, respectively. The holding rod of the lifting frame is provided with an anti-slip coating, which is an epoxy coating with a thickness of 0.8mm. The connecting screw is detachably connected to the first horizontal plate and the second horizontal plate, respectively, and passes through them. The locking nut is threadedly connected to the connecting screw and abuts against the first horizontal plate. The reinforcing plate is welded to the first horizontal plate, the second horizontal plate, and the lifting frame, respectively. The limiting device is respectively located on the side of the first horizontal plate and the second horizontal plate near the tapered sleeve.

[0007] The first semicircular ring is provided with symmetrically arranged positioning protrusions, which can slide into the positioning holes of the second semicircular ring.

[0008] The limiting device includes a support platform and an abutment plate. The support platform is integrally formed with the first horizontal plate. The abutment plate is slidably connected to the conical sleeve and detachably connected to the support platform.

[0009] The connecting screw has a pin hole on the end near the locking nut, and a cotter pin is provided in the pin hole.

[0010] The limiting device further includes a T-shaped rod and a threaded sleeve. The T-shaped rod can be directly slidably inserted into the pin hole provided on the end of the connecting screw near the locking nut. The threaded sleeve is screwed onto the bottom of the T-shaped rod.

[0011] This utility model discloses a hydraulic roller mounting tool for high-speed wire rods. When installing the roller ring and cone sleeve assembly, the first and second semi-circular rings are first fitted into the groove of the roller ring. Then, the assembly is secured by the connecting screw and locking nut. Furthermore, an upper limit device is installed. During operation, the roller ring with this tool is lifted onto the roll shaft. Due to gravity, the roller ring falls axially against the roll shaft. At this point, the assembly is rotated by the rotating lifting frame. When the cone sleeve and the shaft shoulder are aligned, the roller ring and cone sleeve fall freely. Finally, the locking nut is loosened, the connecting screw is removed, and the first and second semi-circular rings are separated, completing the installation of the roller ring and cone sleeve assembly onto the roll shaft. This facilitates quick and convenient replacement and installation of the roller ring and cone sleeve assembly. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the high-speed wire rod hydraulic roller loading tool. Figure 2 This is a schematic diagram of the structure of the first semicircular ring 103. This utility model provides a high-speed hydraulic roller mounting tool: it includes a roller ring 101, a conical sleeve 102, and a locking mechanism.

It is understood that the aforementioned solution allows for quick and convenient replacement and installation of the roller ring and conical sleeve assembly.

[0021] In this embodiment, a tapered sleeve 102 is provided inside the roller ring 101.

[0022] The first semicircular ring 103 and the second semicircular ring 104 can be slidably inserted into the groove of the roller ring 101. The first horizontal plate 105 is welded to the first semicircular ring 103, and the second horizontal plate 106 is welded to the second semicircular ring 104. The lifting frame 107 is welded to the top of the first horizontal plate 105 and the second horizontal plate 106 respectively. The gripping rod of the lifting frame 107 is provided with an anti-slip coating, which is an epoxy coating with a thickness of 0.8mm. The connecting screw 108 is detachably connected to the first horizontal plate 105 and the second horizontal plate 106 respectively and is provided through the plate. The locking nut 109 is threadedly connected to the connecting screw 108 and abuts against the first horizontal plate 105. The reinforcing plate 110 is welded to the first horizontal plate 105, the second horizontal plate 106 and the lifting frame 107 respectively. The limiting device is provided on the side of the first horizontal plate 105 and the second horizontal plate 106 near the tapered sleeve 102. The first horizontal plate 105 is welded to one side of the first semicircular ring 103, and the second horizontal plate 106 is welded to one side of the second semicircular ring 104. The lifting frame 107 is welded and fixed to the first horizontal plate 105 and the second horizontal plate 106 respectively, and an anti-slip coating is provided on the surface of its gripping rod to improve stability when the operator holds it. The connecting screw 108 is T-shaped and passes through the second horizontal plate 106 and the first horizontal plate 105 in sequence. The locking nut 109 is installed on the rear end to limit the movement and prevent it from falling off. The two ends of the reinforcing plate 110 are welded and fixed to improve the stability of the lifting frame 107. The limiting device is used for installation and cooperation.

[0023] Secondly, symmetrically arranged positioning protrusions 111 are provided on the first semi-circular ring 103, and the positioning protrusions 111 can slide into the positioning holes of the second semi-circular ring 104. This structure is used to improve the fit stability between the first semi-circular ring 103 and the second semi-circular ring 104.

[0024] Then, the support platform 112 is integrally formed with the first horizontal plate 105; the abutment plate 113 is slidably connected to the conical sleeve 102 and detachably connected to the support platform 112.

Then, the assembly is secured by the cooperation of the connecting screw 108 and the locking nut 109. Further, the abutment plate 113 is installed. During operation, the roller ring 101, along with this tool, is lifted onto the roll shaft. Because the roller ring 101 is heavy... The roller is pressed down axially. At this time, the assembly is rotated by rotating the lifting frame 107. When the tapered sleeve 102 is aligned with the shoulder, the roller ring 101 and the tapered sleeve 102 fall freely. Finally, the locking nut 109 is loosened and removed. The connecting screw 108 is removed, and the first semi-circular ring 103 and the second semi-circular ring 104 are separated to complete the installation of the roller ring 101 and the tapered sleeve 102 assembly with the roller shaft. This facilitates the quick and convenient replacement and installation of the roller ring 101 and the tapered sleeve 102 assembly.
