Description

Technical Field

[0001] This utility model relates to the field of guide technology, specifically a two-part guide assembly to prevent loosening. Background Technology

[0002] A two-splitting guide is a device used to simultaneously cut a billet into two rolled pieces of the same specification during the rolling process and guide these two rolled pieces to pass smoothly through the subsequent rolling mill. It is one of the core components of two-splitting rolling technology.

[0003] A search revealed a utility model patent with Chinese patent publication number CN216989210U, which discloses a novel two-section guide device, comprising: a housing assembly; two cutting wheel assemblies installed inside the housing assembly and arranged vertically opposite each other, each cutting wheel assembly including a cutting wheel shaft and a cutting wheel rotatably mounted on the cutting wheel shaft, the cutting wheel shaft including a shaft body and an adjustment section eccentrically disposed at one end of the shaft body, the other end of the shaft body being mounted on the housing body via an eccentric bushing.

[0004] As mentioned above, the two cutting blades in the two-stage cutting guide are generally fixed inside the housing. The cutting wheel shaft and bearing are usually connected by interference fit or precision clearance fit, and chemical bonding or permanent fixing is used to prevent loosening. The cutting blades need to withstand a lot of stress during operation. Therefore, as the usage time increases, once a loosening or sticking occurs, it is difficult to repair. Utility Model Content

[0005] The purpose of this invention is to provide a two-part guide assembly that prevents loosening, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a two-section guide assembly for preventing loosening, comprising a housing, an installation component fixedly mounted on the top of the housing, the installation component including a hinge seat fixedly connected to the outer wall of the top of the housing, an installation frame hinged to the outside of the hinge seat, a vertically arranged screw rod 1 fixedly connected to one side of the outer wall of the top of the housing, two nuts threadedly connected to the outside of the screw rod 1, a vertically arranged clearance groove opened on the movable end of the installation frame, and the clearance groove slidably sleeved on the outside of the screw rod 1, and the two nuts respectively fitting against the top and bottom outer walls of the installation frame, and a reinforcing structure installed on the outside of the housing, the reinforcing structure including an installation frame, two screw rods 2, two wheel discs and two contact strips.

[0007] As a further preferred embodiment of this technical solution, the mounting frame is fixedly connected to the outside of the housing by bolts, and the mounting frame is vertically arranged. Both of the two screw rods are threadedly connected to the inside of the mounting frame, and the bottom ends of the two screw rods are respectively located on both sides of the screw rod.

[0008] While ensuring the cutting wheels inside the mounting bracket are securely positioned to prevent easy loosening, the internal space of the housing can be quickly exposed when needed for maintenance. A wrench is used to move the lower nut along screw one, restricting the mounting bracket's movement until the gap between the two cutting wheels reaches the desired position. Then, the wrench is used to move the upper nut along screw one until it contacts the mounting bracket. At this point, the mounting bracket's movement is also restricted. A wheel then rotates screw two, causing it to move downwards along the threaded mounting frame until its bottom end contacts the mounting bracket. This reinforces the mounting bracket's movement, effectively preventing the cutting wheels from loosening. If needed, the restriction on the top of the mounting bracket can be removed by loosening the relevant fixing bolts, allowing the mounting bracket to flip upwards and reveal the internal space of the housing.

[0009] As a further preferred embodiment of this technical solution, a hexagonal column is coaxially fixed at one end of each of the two screws, and the two wheel disks are slidably connected to the outside of the two hexagonal columns respectively.

[0010] As a further preferred embodiment of this technical solution, the two contact strips are respectively fixedly connected to the top outer wall of the mounting frame, and both contact strips are located at the movable end of the mounting frame. A ball head is fixedly connected to one bottom end of each of the two screws, and an arc-shaped groove adapted to the ball head is opened inside the two contact strips.

[0011] As a further preferred embodiment of this technical solution, a horizontally arranged cutting wheel is rotatably connected inside both the housing and the mounting bracket, and the two cutting wheels are arranged opposite to each other. A horizontally arranged cutter is fixedly connected inside the housing, and the cutting edge of the cutter is oriented towards the two cutting wheels.

[0012] As a further preferred embodiment of this technical solution, a support assembly is installed at each of the two corners at the bottom of the housing, and the two support assemblies are symmetrically arranged. The support assembly includes two mounting shafts fixedly connected to the corners of the outer walls at both ends of the housing. The two mounting shafts are rotatably connected to the same support frame. Several equidistant limiting holes are opened on the outer walls at both ends of the housing. A support rod is threadedly connected to the outer walls at both ends of the support frame. The two support rods are slidably inserted into two of the limiting holes at both ends.

[0013] If there is a height difference between the external feeding and receiving equipment, or if the height is insufficient, first suspend the part that needs to be adjusted in the air. Then, remove the support rod from the support frame and the limiting hole. At this time, the support frame will no longer be restricted and can be flipped freely along the installation axis. Taking the adjustment of the housing inlet and outlet as an example, flip the support frame downward and push the support rod to insert it into a limiting hole at the corresponding position. At this time, the position of the support frame will be restricted again. When the housing is placed on the ground again, the support frame can support the corresponding end of the housing.

[0014] As a further preferred embodiment of this technical solution, the movable end of the support frame is configured as a semi-circular head, and two mounting slots are provided at the end of the movable end of the support frame. A rotating shaft is hinged inside each of the two mounting slots. An extension plate is fixedly connected to the outside of the rotating shaft. The central axis of the rotating shaft coincides with the center of the semi-circular head of the movable end of the support frame, and the lower surface of the extension plate is tangent to the semi-circular head.

[0015] As a further preferred embodiment of this technical solution, the thread helix angle of the external threads of the first screw and the two second screws is less than the equivalent friction angle.

[0016] This utility model provides a two-section guide assembly to prevent loosening, which has the following beneficial effects:

[0017] (1) By setting up the installation components, this utility model ensures that the position of the cutting wheels installed inside the mounting frame is firm enough and will not easily loosen. At the same time, it can also quickly expose the internal space of the shell when needed, which is convenient for maintenance work. By using a wrench to drive the lower nut to move along the screw one, the movable end of the mounting frame will be restricted from moving down until the gap between the two cutting wheels reaches the required position. Then, by using a wrench to drive the upper nut to move along the screw one until it contacts the mounting frame, the movable end of the mounting frame cannot move up. Then, by using a wheel to drive the screw two to rotate, the screw two will move down along the mounting frame that is threaded to it until the bottom end of the screw two contacts the mounting frame. The movable end of the mounting frame will be reinforced, effectively preventing the cutting wheels installed inside from loosening. When needed, the restriction on the top of the mounting frame can be removed by loosening the relevant fixing bolts. At this time, the mounting frame can be flipped up, and the internal space of the shell will be exposed.

[0018] (2) By setting up a support component, if there is a difference in height between the external feeding equipment and receiving equipment, or if the height is insufficient, the part that needs to be adjusted is first lifted and suspended in the air. Then, the support rod is taken out from the support frame and the limiting hole. At this time, the support frame will no longer be restricted and can be flipped along the installation axis at will. Taking the adjustment of the housing inlet and outlet as an example, the support frame is flipped downwards and the support rod is pushed to be inserted into a limiting hole at the corresponding position again. At this time, the position of the support frame will be restricted again. When the housing is placed on the ground again, the support frame can support the corresponding end of the housing.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figure 2 and Figure 4 As shown, in this embodiment, a two-section guide assembly for preventing loosening includes a housing 1. An installation component 4 is fixedly installed on the top of the housing 1. The installation component 4 includes a hinge seat 401 fixedly connected to the outer wall of the top of the housing 1. An installation frame 402 is hinged to the outside of the hinge seat 401. A vertically arranged screw rod 403 is fixedly connected to one side of the outer wall of the top of the housing 1. Two nuts 404 are threadedly connected to the outside of the screw rod 403. A vertically arranged clearance groove is opened at the movable end of the installation frame 402, and the clearance groove is slidably sleeved on the outside of the screw rod 403. The two nuts 404 are respectively attached to the top outer wall and the bottom outer wall of the installation frame 402. A reinforcing structure is installed on the outside of the housing 1. The reinforcing structure includes an installation frame 405, two screw rods 406, two wheel discs 407, and two contact strips 408.

[0026] Mounting frame 405 is fixedly connected to the outside of housing 1 by bolts, and mounting frame 405 is set vertically. Two screw rods 406 are threadedly connected inside mounting frame 405, and the bottom ends of the two screw rods 406 are respectively located on both sides of screw rod 403.

[0027] Each of the two screws 406 has a hexagonal post fixed coaxially at one end. Two discs 407 are slidably connected to the outside of the two hexagonal posts. When needed, the discs 407 can be fitted onto the outside of the hexagonal posts to drive the screws 406. When not needed, the discs 407 can be removed to avoid accidental activation.

[0028] Two contact strips 408 are fixedly connected to the top outer wall of the mounting bracket 402, and both contact strips 408 are located at the movable end of the mounting bracket 402. A ball head is fixedly connected to one bottom end of each of the two screw rods 406. The two contact strips 408 have arc-shaped grooves that fit the ball heads, which helps to improve the contact surface between the screw rods 406 and the mounting bracket 402, thereby preventing damage to the mounting bracket 402.

[0029] By using a wrench to move the lower nut 404 along the screw 403, the movable end of the mounting bracket 402 will be restricted from moving downwards until the gap between the two cutting wheels 3 reaches the required position. Then, by using a wrench to move the upper nut 404 along the screw 403 until it contacts the mounting bracket 402, the movable end of the mounting bracket 402 will also be unable to move upwards. Then, the wheel 407 will drive the screw 406 to rotate, and the screw 406 will move downwards along the mounting frame 405 connected to it until the bottom end of the screw 406 contacts the mounting bracket 402. The movable end of the mounting bracket 402 will be reinforced, effectively preventing the cutting wheels 3 installed inside from loosening. When necessary, the restriction on the top of the mounting bracket 402 can be removed by loosening the relevant fixing bolts. At this time, the mounting bracket 402 can be flipped upwards, and the internal space of the housing 1 will be exposed.

[0030] like Figure 2 As shown, a horizontally arranged cutting wheel 3 is rotatably connected inside the housing 1 and the mounting bracket 402, and the two cutting wheels 3 are arranged opposite to each other. A horizontally arranged cutter 2 is fixedly connected inside the housing 1, and the cutting edge of the cutter 2 is arranged towards the two cutting wheels 3.

[0031] like Figure 2 and Figure 3 As shown, a support component 5 is installed at each of the two corners at the bottom of the housing 1, and the two support components 5 are arranged symmetrically. The support component 5 includes two mounting shafts 501 fixedly connected to the corners of the outer walls at both ends of the housing 1. The two mounting shafts 501 are rotatably connected to the same support frame 502. Several equidistant limiting holes 503 are opened on the outer walls at both ends of the housing 1. A support rod 504 is threadedly connected to the outer walls at both ends of the support frame 502. The two support rods 504 are slidably inserted into the two limiting holes 503 at both ends.

[0032] If there is a height difference between the external feeding equipment and receiving equipment, or if the height is insufficient, first suspend the part that needs to be adjusted in the air. Then, remove the support rod 504 from the support frame 502 and the limiting hole 503. At this time, the support frame 502 will no longer be restricted and can be flipped freely along the mounting shaft 501. Taking the adjustment of the inlet and outlet of the housing 1 as an example, flip the support frame 502 downward and push the support rod 504 to insert it into a limiting hole 503 at the corresponding position. At this time, the position of the support frame 502 will be restricted again. When the housing 1 is placed on the ground again, the support frame 502 can support the corresponding end of the housing 1.

[0033] The movable end of the support frame 502 is set as a semi-circular head. Two mounting slots are opened at the end of the movable end of the support frame 502, and a rotating shaft 505 is hinged inside each of the two mounting slots. An extension plate 506 is fixedly connected to the outside of the rotating shaft 505. The central axis of the rotating shaft 505 coincides with the center of the semi-circular head of the movable end of the support frame 502, and the lower surface of the extension plate 506 is tangent to the semi-circular head.

[0034] Since the movable end of the support frame 502 is semi-circular, and the rotating shaft 505 coincides with the center of the semi-circular head of the support frame 502, and the extension plate 506 is tangent to the semi-circular head of the support frame 502, the extension plate 506 can adjust its angle with the support frame 502 regardless of how the support frame 502 is rotated. When the semi-circular head of the support frame 502 contacts the ground, the extension plate 506 will also be completely in contact with the ground, and can be connected and fixed to the ground structure using bolts.

[0035] like Figure 1 and Figure 2 As shown, the thread helix angle of the external threads of screw 403 and the two screws 406 is less than the equivalent friction angle, which gives both of them self-locking characteristics and can further prevent loosening problems.

[0036] This utility model provides a two-section guide assembly to prevent loosening, and its specific working principle is as follows:

[0037] When the device is in operation, the lower nut 404 is moved along the screw 403 by a wrench. Under its restriction, the movable end of the mounting bracket 402 will be restricted from moving downward until the gap between the two cutting wheels 3 reaches the required position. Then, the upper nut 404 is moved along the screw 403 by a wrench until it contacts the mounting bracket 402. At this time, the movable end of the mounting bracket 402 cannot move upward. Then, the screw 406 is rotated by the wheel 407. The screw 406 will move downward along the mounting frame 405 that is threaded to it until the bottom end of the screw 406 contacts the mounting bracket 402. The movable end of the mounting bracket 402 will be reinforced, effectively preventing the cutting wheels 3 installed inside from loosening. When needed, the restriction on the top of the mounting bracket 402 can be removed by loosening the relevant fixing bolts. At this time, the mounting bracket 402 can be flipped upward, and the internal space of the housing 1 will be exposed.

[0038] If there is a height difference or insufficient height between the external feeding and receiving equipment, first suspend the part that needs adjustment in the air. Then, remove the support rod 504 from the support frame 502 and the limiting hole 503. At this time, the support frame 502 will no longer be restricted and can be rotated freely along the mounting axis 501. Taking the adjustment of the inlet and outlet of the housing 1 as an example, rotate the support frame 502 downwards and push the support rod 504 to insert it into the corresponding limiting hole 503. At this time, the position of the support frame 502 will be restricted again. When the housing 1 is placed on the ground again... When the support frame 502 is in use, it can support the corresponding end of the housing 1. Furthermore, since the movable end of the support frame 502 is semi-circular, and the rotation shaft 505 coincides with the center of the semi-circular head of the support frame 502, and the extension plate 506 is tangent to the semi-circular head of the support frame 502, the extension plate 506 can adjust its angle as the support frame 502 is rotated, regardless of how the support frame 502 is rotated. When the semi-circular head of the support frame 502 contacts the ground, the extension plate 506 will also be completely in contact with the ground, and can be connected and fixed to the ground structure using bolts.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
