A saw cover for cooling a saw blade

Abstract

The utility model discloses a saw cover for cooling saw blade, which aims to solve the problem of insufficient cooling of the saw blade, which leads to abrasion and cracking of the saw blade during sawing, caused by the splashing of cooling water with the high-speed rotation of the saw blade. The saw cover comprises a saw cover body (with a saw blade mounting hole in the center), an upper baffle integrally formed with the saw cover body, and a transparent acrylic side baffle connected to the upper baffle by bolts. Five conical flow guide plates are symmetrically distributed about the center line of the saw cover on the inner side of the upper baffle, covering a 120° working area and having retractable flow guide grooves. During operation, the flow guide plates collect the splashing cooling water, which is then subjected to secondary flushing through the flow guide grooves to form a circulating cooling of the saw blade. The saw cover can improve the cooling efficiency, prolong the service life of the saw blade, simplify maintenance, realize sawing visualization, reduce the splashing of cooling water, and improve the working environment.

Description

Technical Field

[0001] This utility model relates to the field of cutting saw technology, specifically a saw cover for cooling saw blades. Background Technology

[0002] The main processes in the production of structural steel include heating in a heating furnace, rolling on a roughing mill, rolling on a medium and finishing mill, flying shearing, cooling, straightening, cold sawing, inspection, and packaging.

[0003] The small H-beam steel branch of Maanshan Iron & Steel's long products division uses two cold saws for fixed-length cutting. The saw blade diameter is generally between 1600mm and 1800mm. During the sawing process, the saw blades suffer from severe wear and cracking. The two saws use about 400 saw blades per year. The reason for the saw blade damage is that the cooling water is sprayed out with the high-speed rotation of the saw blade during use, and the saw blade is not continuously and adequately cooled. Utility Model Content

[0004] The purpose of this invention is to provide a saw cover for cooling saw blades to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a saw cover for cooling saw blades, comprising a saw cover body, a saw blade mounting hole provided at the center of the saw cover body for mounting the saw blade, an upper baffle provided at the edge of the saw cover body, and a detachable side baffle installed on the side wall of the upper baffle. The upper baffle, the side baffle, and the saw cover body together cover the edge of the saw blade. Multiple conical guide plates are installed on the inner side of the upper baffle, and the drain outlet of the conical guide plates points to the saw blade position. The conical guide plates are used to collect the water thrown off the saw blade and rinse the saw blade.

[0006] Preferably, the conical guide plate is provided with a guide groove, the guide groove faces the rotation direction of the saw blade, the guide groove is converging from top to bottom, and the drain port at the bottom of the guide groove is directly facing the saw blade.

[0007] Preferably, five conical guide plates are evenly arranged and symmetrically distributed about the centerline of the saw cover body, with a distribution range of 120°.

[0008] Preferably, the conical guide plate is fixed to the upper baffle by bolt connection.

[0009] Preferably, the upper baffle side end and the side baffle side wall are provided with corresponding mounting holes, and the two are fixed by screwing bolts into the mounting holes.

[0010] Preferably, the side baffle is made of transparent acrylic sheet.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. Significantly improves saw blade cooling efficiency and extends saw blade lifespan.

[0013] This invention utilizes symmetrically distributed conical guide plates on the inner side of the upper baffle, employing a "top-to-bottom converging guide channel design facing the saw blade's rotation direction." This efficiently collects the cooling water ejected during high-speed saw blade rotation and then precisely rinses it back onto the saw blade surface through the drain outlet at the bottom of the guide channel, forming a "jet cooling - ejection and collection - secondary rinsing" circulating cooling path. This design completely solves the pain points of traditional saw blades, such as "easy cooling water loss and inconsistent cooling," ensuring that the saw blade remains fully cooled throughout the entire sawing process. This significantly reduces the probability of saw blade wear and cracking due to high temperatures, decreases the frequency of saw blade replacement, and consequently reduces the annual usage of saw blades, saving companies saw blade procurement costs.

[0014] 2. The detachable design of the saw cover significantly reduces maintenance difficulty:

[0015] On the one hand, the side baffle is connected to the upper baffle by bolts and corresponding mounting holes. When replacing or repairing the saw blade, only the bolts need to be unscrewed to remove the side baffle, without the need to disassemble the entire saw cover, saving maintenance time. On the other hand, the conical guide plate is fixed to the upper baffle by bolts. When the guide plate is blocked or worn, it can be disassembled and cleaned or replaced separately without the need to maintain the saw cover itself, reducing maintenance complexity and cost.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The saw cover for cooling saw blades provided in this embodiment is primarily used to solve the problem of insufficient cooling and easy wear and cracking of saw blades when cutting small H-beams with diameters of 1600mm~1800mm using cold saw blades at high speeds, causing cooling water to fly out and resulting in the saw blades being prone to wear and cracking. The specific assembly steps are as follows:

[0022] refer to Figure 1-2 The saw blade mounting base is constructed with the saw cover body 1 as the core carrier. The saw blade mounting hole 2 in the center of the body must be compatible with the mounting shaft of the cold saw blade. During assembly, the saw blade is fixed through the mounting hole 2 to ensure that the rotation center of the saw blade coincides with the center of the saw cover body 1, providing a positioning reference for the subsequent cooling structure.

[0023] Assembly of the upper baffle 4 and the side baffle 6: The upper baffle 4 is integrally formed on the edge of the saw cover body 1. The side end of the upper baffle 4 and the side wall of the side baffle 6 are both pre-set with mounting holes 5 of corresponding specifications. During assembly, the side baffle 6 is attached to the side end of the upper baffle 4 so that the mounting holes 5 are aligned, and then the bolts are screwed into the mounting holes 5 to complete the fixation. The side baffle 6 is made of transparent acrylic sheet material, which can not only cover the edge of the saw blade together with the upper baffle 4 and the saw cover body 1 to prevent cooling water from splashing to the outside, but also make it easy for the operator to observe the sawing status of the saw blade.

[0024] refer to Figure 3 Fixing and positioning of the conical guide plates 3: Five conical guide plates 3 are fixed to the inside of the upper baffle 4 by bolts. These five conical guide plates 3 are symmetrically distributed about the center line of the saw cover body 1, and the distribution range covers 120° to ensure coverage of the main working area of ​​the saw blade. Each conical guide plate 3 is provided with a guide groove. The direction of the guide groove must be facing the direction of rotation of the saw blade, and the guide groove is designed to taper from top to bottom. The drain port at the bottom must be precisely aligned with the surface of the saw blade - this structural design can maximize the collection of cooling water thrown out when the saw blade rotates at high speed.

[0025] Working principle and cooling process:

[0026] When the cold saw is started to cut steel sections to length, the saw blade rotates at high speed through the saw blade mounting hole 2, and the external cooling system sprays cooling water onto the saw blade to reduce the sawing temperature; during this process:

[0027] After some of the cooling water is applied directly to the cutting part of the saw blade, it is thrown out into the saw cover as the saw blade rotates;

[0028] After being blocked by the upper baffle 4, the ejected cooling water flows into the guide groove of the conical guide plate 3. Due to the "facing the direction of saw blade rotation + converging" design of the guide groove, the cooling water will gather in the guide groove and flow downward along the groove.

[0029] Finally, the cooling water is sprayed again onto the surface of the saw blade through the drain outlet at the bottom of the guide channel, especially the area where the saw blade is about to enter the next cut, forming a "jet cooling-collection-secondary spraying" circulating cooling path to ensure that the saw blade is continuously and fully cooled throughout the sawing process.

[0030] Ease of maintenance and adjustment:

[0031] If the saw blade needs to be replaced or repaired, the bolts connecting the side baffle 6 and the upper baffle 4 can be unscrewed. After removing the side baffle 6, the saw blade can be operated directly without disassembling the entire saw cover.

[0032] If the conical guide plate 3 becomes clogged or worn, the bolts connecting it to the upper baffle 4 can be unscrewed for cleaning or replacement, making maintenance simple and efficient.

[0033] This embodiment effectively solves the problems of easy water splashing and insufficient cooling in traditional cold saw blades through the above structural design. Practical application verification has shown that it can significantly reduce the probability of saw blade wear and cracking, reduce the frequency of saw blade replacement, and is expected to reduce the annual usage of saw blades and extend the service life of saw blades. It is suitable for cold saw blades with diameters of 1600mm~1800mm, and is especially suitable for similar cold sawing scenarios of steel section cold sawing such as the small H-beam steel branch of Maanshan Iron & Steel Long Products Division.

[0034] 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.
