Description

Technical Field

[0001] This utility model relates to the technical field of finishing mill production line equipment, and specifically discloses a finishing mill exit transition plate. Background Technology

[0002] In the hot or cold rolling finishing production line of the metallurgical industry, after being rolled from the last stand of the finishing mill, the strip steel is thrown at high speed towards the exit area and passes through a guiding device before it can stably enter the coiler or downstream equipment. The finishing mill exit transition plate (or guide plate, guard plate) is a core guiding component installed at this critical position. Its core function is to instantly support and guide the head of the strip steel, preventing it from tilting, buckling, or deviating, thus ensuring the smoothness and stability of the production process.

[0003] Currently, the commonly used exit transition plates in the industry are mostly integral structures or split wear-resistant plate structures secured with bolts. Integral transition plates require complete replacement after their guide surfaces wear down, resulting in high material costs and time-consuming, labor-intensive replacement operations, leading to extended production line downtime. To address the issue of easy wear, a split structure has emerged, where wear-resistant plates are fixed to the base plate with multiple bolts. While this reduces material consumption to some extent, the installation and fixing of the wear-resistant plates requires operators to tighten a large number of bolts one by one. Given the harsh environment and high temperature at the finish mill exit area, this operation is extremely tedious and labor-intensive. Therefore, a new type of finish mill exit transition plate is needed to solve this problem. Utility Model Content

[0004] This invention proposes a transition plate for the exit of a finishing mill. Through a linkage snap-fit ​​mechanism driven by a rotating shaft, it enables the rapid and synchronous disassembly and assembly of all wear-resistant plates. While ensuring the reliability of the fixation, it significantly improves the replacement efficiency and reduces the maintenance cost.

[0005] This utility model is implemented as follows: a transition plate at the exit of a finishing mill includes a transition guide plate and multiple wear-resistant plates. The upper end face of the transition guide plate is provided with a groove that matches the wear-resistant plates. The upper end face of the groove is provided with multiple recesses. The lower end face of each of the multiple wear-resistant plates is fixedly connected with a protrusion that matches the groove. The upper end face of each of the multiple recesses is provided with a slot. The lower end face of each of the multiple protrusions is fixedly connected with a locking block located inside the slot. The locking block is detachably connected to the transition guide plate through a locking mechanism.

[0006] The snap-fit ​​mechanism includes a rotating shaft rotatably connected inside the transition guide plate. The outer wall of the rotating shaft is provided with multiple bidirectional threads located inside the slots. Inside each of the multiple slots are two sliding plates that are threadedly connected to the rotating shaft through the bidirectional threads.

[0007] As a preferred embodiment of the finishing mill exit transition plate of this utility model, two sliding plates located in the same slot are fixedly connected to two locking rods on their opposite outer walls, and two locking holes matching the locking rods are opened through the outer wall of the locking block.

[0008] As a preferred embodiment of the finishing mill exit transition plate of this utility model, the inner wall of the transition guide plate is fixedly connected to a limit rod, and the plurality of slide plates are slidably connected to the limit rod.

[0009] As a preferred embodiment of the present invention, the front side of the upper surface of the transition guide plate is set in an arc shape, and the rear side of the upper surface of the wear-resistant plate is inclined.

[0010] As a preferred embodiment of the finishing mill exit transition plate of this utility model, the upper end surface of the wear-resistant plate is provided with a wear-resistant coating.

[0011] As a preferred embodiment of the finishing mill exit transition plate of this utility model, the upper end face of the settling groove has two mounting holes.

[0012] The beneficial effects of this utility model are:

[0013] 1. By driving multiple locking mechanisms through a single rotating shaft, all wear-resistant plates can be locked or released simultaneously. Compared with the traditional method of tightening bolts one by one, this greatly improves replacement efficiency, reduces operational intensity and downtime. At the same time, the clamping cooperation between the locking block and the sliding plate, as well as the interlocking between the locking rod and the locking hole, ensures a firm and reliable fixation.

[0014] 2. The design separates the wear-resistant plate from the base transition guide plate, so that only the wear-resistant plate module needs to be replaced after wear, which significantly saves material and maintenance costs; and an ultra-hard wear-resistant coating is applied to its working surface, which specifically improves wear resistance and scratch resistance, thereby extending the service life of core components while ensuring the surface quality of the strip steel.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-4 A transition plate for the exit of a finishing mill includes a transition guide plate 1 and multiple wear-resistant plates 2. The upper end face of the transition guide plate 1 is provided with a groove 3 that matches the wear-resistant plates 2. The upper end face of the groove 3 is provided with multiple grooves 4. The lower end face of each of the multiple wear-resistant plates 2 is fixedly connected with a protrusion 5 that matches the groove 4. The upper end face of each of the multiple grooves 4 is provided with a slot 6. The lower end face of each of the multiple protrusions 5 is fixedly connected with a locking block 7 located inside the slot 6. The locking block 7 is detachably connected to the transition guide plate 1 through a locking mechanism.

[0023] The snap-fit ​​mechanism includes a rotating shaft 8 rotatably connected inside the transition guide plate 1. The outer wall of the rotating shaft 8 is provided with multiple bidirectional threads located inside the slots 6. Each of the multiple slots 6 is provided with two sliding plates 9 that are threadedly connected to the rotating shaft 8 through the bidirectional threads.

[0024] In this embodiment: When replacing the wear-resistant plate 2, the rotating shaft 8 is turned by the knob. The rotating shaft 8 drives the two sliding plates 9 in the same slot 6 to move synchronously in opposite directions, causing the locking rod 10 to disengage from the locking hole 11, thus removing the wear-resistant plate 2. The new wear-resistant plate 2 is placed in the recess 3, with the protrusion 5 aligned with the groove 4. The locking block 7 enters between the two sliding plates 9 in the slot 6. The rotating shaft 8 is then turned in the opposite direction, causing the two sliding plates 9 in the same slot 6 to move synchronously towards each other, clamping and fixing the locking block 7. At the same time, the locking rod 10 engages in the locking hole 11, further fixing the locking block 7, thereby fixing the wear-resistant plate 2. This utility model, with its replaceable wear-resistant plate 2, eliminates the need to replace the entire transition guide plate 1 and allows for the simultaneous installation and removal of multiple wear-resistant plates 2, solving the problem of cumbersome operation that previously required tightening multiple bolts. It achieves higher economic benefits while maintaining replacement efficiency.

[0025] As a technical optimization of this utility model, two sliding plates 9 located in the same slot 6 are fixedly connected to two locking rods 10 on their opposite outer walls, and two locking holes 11 matching the locking rods 10 are opened through the outer wall of the locking block 7.

[0026] In this embodiment: the clip 10 is inserted into the clip hole 11 to further fix the clip 7, so that the wear-resistant plate 2 is installed firmly.

[0027] As a technical optimization of this utility model, the inner wall of the transition guide plate 1 is fixedly connected to the limiting rod 12, and multiple slide plates 9 are slidably connected to the limiting rod 12.

[0028] In this embodiment, the limiting rod 12 facilitates the limiting of the slide plate 9, making the slide plate 9 slide stably.

[0029] As a technical optimization of this utility model, the front side of the upper end face of the transition guide plate 1 is set as an arc shape, and the rear side of the upper end face of the wear-resistant plate 2 is a slope.

[0030] In this embodiment, by setting the front end of the transition guide plate 1 as an arc surface and the rear end of the wear-resistant plate 2 as an inclined surface, a smooth transition guide surface is formed, which can effectively guide the strip head to pass smoothly and prevent impact and jamming.

[0031] As a technical optimization of this utility model, the upper surface of the wear-resistant plate 2 is provided with a wear-resistant coating.

[0032] In this embodiment, the wear-resistant plate 2 is coated with a tungsten carbide or chromium oxide ceramic wear-resistant coating by plasma spraying, which directly and effectively improves the wear resistance and scratch resistance of the wear-resistant plate 2, thereby extending its service life and ensuring the surface quality of the strip steel.

[0033] As a technical optimization of this utility model, two mounting holes are provided on the upper end face of the settling tank 3.

[0034] In this embodiment, two mounting holes are provided on the upper end face of the sink 3 to facilitate the fixing of the transition guide plate 1 with countersunk bolts.

[0035] The working principle and usage process of this utility model are as follows: When replacing the wear-resistant plate 2, the rotating shaft 8 is turned by the knob. The rotating shaft 8 drives the two sliding plates 9 in the same slot 6 to move synchronously in opposite directions, so that the locking rod 10 is disengaged from the locking hole 11, and the wear-resistant plate 2 can be removed. The new wear-resistant plate 2 is placed in the sink 3, so that the protrusion 5 is aligned with the groove 4, and the locking block 7 enters between the two sliding plates 9 in the slot 6. The rotating shaft 8 is rotated in the opposite direction, and the rotating shaft 8 drives the two sliding plates 9 in the same slot 6 to move synchronously in opposite directions, clamping and fixing the locking block 7. At the same time, the locking rod 10 is inserted into the locking hole 11, further fixing the locking block 7, thereby fixing the wear-resistant plate 2.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
