Description

Technical Field

[0001] This application belongs to the field of wire rod production technology, and in particular relates to a rolling mill with a safety guard. Background Technology

[0002] In the production of high-speed wire rod, the rolling area is often equipped with alternating horizontal and vertical short-stress rolling mills. During the rolling process, a suitable material shape is given to each rolling mill according to the process requirements, so that the cross-sectional shape and size of the rolled piece meet the production requirements, thereby producing high-quality wire rod products that meet the requirements and ensuring the smooth progress of production.

[0003] Currently, setting the material profile for a rolling mill requires starting the mill, with workers approaching the mill to feed a lead sample through the inlet guide. The rotating upper and lower rollers then carry the lead sample out through the outlet guide. The lead sample is then removed, and its dimensions are measured to determine the material profile. However, workers are very close to the high-speed rotating mill during the lead sample feeding process. If they lose their footing, they can be pulled into the mill, leading to frequent accidents. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, this application provides a rolling mill with a safety guard, which can greatly improve safety and avoid injury to the human body from the rolling mill.

[0005] To achieve the above objectives, the technical solution provided in this application is as follows:

[0006] This application provides a rolling mill with a safety guard, including a roll box and a cover. A roll set is rotatably connected to the roll box, and the roll set includes two rolls rotatably connected to the roll box. The workpiece passes through the gap between the two rolls and is rolled by the cooperation of the two rolls. A water cooling mechanism is provided on the roll box. The water cooling mechanism is arranged on both sides of the roll set along the line connecting the two rolls. The cover is placed outside the roll set and the water cooling mechanism and is engaged with the water cooling mechanism. The cover has an opening at the workpiece inlet and outlet, and a viewing hole is provided on the cover for checking the running status of the rolls.

[0007] Optionally, when the roller box is installed vertically, the two rollers are arranged vertically, and the top wall of the water cooling mechanism at the top of the upper roller is provided with an insertion groove. The inner side of the top wall of the cover is provided with a positioning block, which is inserted into the insertion groove. The cover has no bottom wall.

[0008] Optionally, the positioning block is fitted to the wall of the insertion slot.

[0011] Optionally, the housing is provided with a handle.

[0012] Optionally, it also includes a guide, which is arranged at the inlet and outlet of the roll group, with the guide opposite to the gap between the two rolls, and the guide passing through the opening of the cover.

[0013] Optionally, the housing may have multiple viewing holes, which may also be used for heat dissipation.

[0014] Compared with the prior art, this application has at least the following beneficial effects:

[0015] This application utilizes a water-cooling mechanism to cool the rolls and employs a casing to isolate the high-speed rotating rolls from the external environment, preventing injury from the rotating rolls. Furthermore, the casing is directly engaged with the water-cooling mechanism and can be easily removed after the material shape is determined. The viewing holes on the casing facilitate observation of the rolls' operating status by workers and also aid in heat dissipation.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0026] Example 1

[0027] like Figures 1-2 As shown, a rolling mill with a safety guard includes a roll box 1 and a cover 4. A roll set 2 is rotatably connected to the roll box 1. The roll set 2 includes two rolls 21 rotatably connected to the roll box 1. The workpiece passes through the gap between the two rolls 21 and is rolled by the cooperation of the two rolls 21. A water cooling mechanism 3 is provided on the roll box 1. The water cooling mechanism 3 is arranged on both sides of the roll set 2 along the line connecting the two rolls 21. The cover 4 is placed on the outside of the roll set 2 and the water cooling mechanism 3 and is engaged with the water cooling mechanism 3. The cover 4 has an opening 41 at the workpiece inlet and outlet position to facilitate the workpiece passing through. The cover 4 has a viewing hole 42 for checking the running status of the rolls 21.

[0028] The water-cooling mechanism 3 cools the roller 21, and the cover 4 isolates the high-speed rotating roller 21 from the outside environment, preventing injury from the rotating roller 21. Furthermore, the cover 4 is directly engaged with the water-cooling mechanism 3, allowing for easy removal after the material is shaped. The inspection hole 42 on the cover 4 facilitates observation of the roller 21's operating status and also aids in heat dissipation. This device significantly reduces the occurrence of accidents, has a simple structure, and is highly practical.

[0029] In this embodiment, the roller box 1 is installed horizontally, and the water cooling mechanism 3 is arranged horizontally. The inner wall of the cover 4 is engaged with the outer peripheral wall of the water cooling mechanism 3. After the material shape is given, the cover 4 can be removed by simply moving it upwards.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that: Figures 3-5As shown, in this embodiment, the roller box 1 is installed vertically, and the two rollers 21 are arranged vertically. The top wall of the water cooling mechanism 3 at the top of the upper roller 21 is provided with an insertion groove 31. The inner side of the top wall of the cover 4 is provided with a positioning block 43, which is inserted into the insertion groove 31. The cover 4 has no bottom wall, and the positioning block 43 fits against the groove wall of the insertion groove 31.

[0032] By utilizing the cooperation between the positioning block 43 and the insertion slot 31, the positioning block 43 cannot wobble after being inserted into the insertion slot 31, thus ensuring the stability of the housing 4 during installation. In this embodiment, there are two positioning blocks 43, which respectively fit into the two ends of the horizontal direction of the insertion slot 31. In other embodiments, the positioning block 43 can also be set as one or other types, as long as it ensures that the positioning slot is stable and does not wobble after being inserted into the insertion slot 31.

[0033] In this embodiment, multiple viewing holes 42 are arranged on the cover 4 to facilitate heat dissipation.

[0034] The rolling mill with a safety guard in this embodiment also includes a guide 22, which is arranged at the inlet and outlet of the roll group 2. The guide 22 is opposite to the gap between the two rolls 21, and the guide 22 passes through the openings 41 on both sides of the cover 4.

[0035] The cover 4 is equipped with a handle 5 for easy installation or removal. By holding the handle 5 and aligning the positioning block 43 with the positioning groove, the cover 4 can be moved downwards to complete the installation. After use, the cover 4 can be easily removed by moving it upwards.
