Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plate blank processing technology, in particular to a tool and deburring machine for chamfered plate blank deburring of continuous casting. BACKGROUND

[0002] After the plate blank is formed by continuous casting, it is cut into segments by a flame cutting machine according to a certain length to form primary iron oxide tumors, and then is transported to a plate line for secondary cutting to form a fixed size. During the flame cutting, the lower edge of each cut of the steel blank is adhered to steel slag (referred to as steel blank burr). The burr has a large hardness. If the burr is not removed or is not completely removed, it may be embedded in the steel plate during the subsequent rolling process, resulting in unqualified steel plate quality and waste products, and also causing great damage to the rolls. Therefore, the production efficiency and production cost of the enterprise are directly affected.

[0003] In the prior art, a deburring machine is mainly used to scrape the burr. As shown in FIG. Figure 1 A plurality of groups of independently arranged tools are installed on the deburring machine. Each group of tools includes an elastic tool holder and a blade. During the deburring process of the plate blank, each group of tools moves along the direction perpendicular to the plate blank conveying path to complete the scraping. During the movement of the plate blank for deburring, the two adjacent groups of tools near the edge of the plate blank are in a compressed state and a normal state. Since there is no connecting structure between the adjacent tools, the tools cannot be pressed synchronously. During the movement of the plate blank, the narrow edge chamfer surface of the plate blank contacts the blade edge of the tool that is not pressed, causing scratches, affecting the quality of the finished plate blank, and reducing the production efficiency.

[0025] In the description of the present application, it should be understood that the terms "first", "second" and the like are used to describe various information in the present application, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, "first" information can also be referred to as "second" information without departing from the scope of the present application, and similarly, "second" information can also be referred to as "first" information.

[0026] As shown in the prior art, Figure 1 Since each group of adjacent cutters is independently arranged and cannot be linked, when the slab moves along the first direction X to remove burrs, one of the adjacent cutters is in a compressed state and the other cutter is in a normal state at the edge of the slab, the chamfered surface of the narrow edge of the slab contacts the blade 2 cutting edge of the cutter not pressed, causing scratches and affecting the finished product quality of the slab.

[0027] As shown in the prior art, Figures 2 to 7 The present application provides a kind of cutter for continuous casting chamfered slab deburring, with two perpendicular first direction X, second direction Y and third direction Z, including elastic cutter holder 1 and blade 2, wherein, first direction X is the length direction of blade 2, second direction Y is the width direction of blade 2, third direction Z is the height direction of blade 2. Specifically, elastic cutter holder 1 (the structure of elastic cutter holder 1 is existing conventional technology, as shown in Figure 7 Therefore, its structure is not described) is arranged along third direction Z, the bottom of elastic cutter holder 1 is connected with deburring machine, the top of elastic cutter holder 1 is connected with blade 2, in order to realize the linkage between the blades 2 of adjacent cutters, the two ends of blade 2 in first direction X are provided with first step surface 21 and second step surface 22, first step surface 21 and second step surface 22 are arranged in third direction Z, the two ends of blade 2 in second direction Y are provided with sawtooth-shaped cutting edge 23, first step surface 21 and second step surface 22 of adjacent two blades 2 are arranged in third direction Z, form clamping structure, refer to Figure 2 、 Figure 6When the slab is deburred, the slab compression synchronously compresses the adjacent knives located outside the slab and adjacent to the knives deburring under the edge of the slab, the two adjacent groups of knives are synchronously compressed, the narrow edge chamfer surface of the slab and the blade 2 cutting edge of the knives not compressed are prevented from contacting and scratching, the quality of the finished slab is ensured, and the production efficiency and the yield are improved.

[0028] In some embodiments, in order to ensure the structural strength of the blade 2, the opening depth of the first step surface 21 and the second step surface 22 on the blade 2 needs to be set, as shown in Figure 5 , the opening depth of the first step surface 21 in the third direction Z is L1, the opening depth of the second step surface 22 in the third direction Z is L2, and the maximum length of the blade 2 in the third direction Z is L, which satisfies L1=L2 and L1+L2≤L, that is, L1≤0.5L. When L1 is much smaller than 0.5L, the clamping between adjacent blades 2 is not firm enough. When L1>0.5L, the overall strength of the blade 2 is weak and is easily damaged, which needs to be frequently replaced, affecting the production efficiency.

[0029] In some embodiments, in order to ensure the structural strength of the blade 2 and facilitate processing and linkage effect between adjacent knives, refer to Figure 5 , the length of the first step surface 21 in the first direction X is W1, the length of the second step surface 22 in the first direction X is W2, and the maximum length of the blade 2 in the first direction X is W, which satisfies W1=W2 and 1 / 3W≤W1≤1 / 2W. W1 can be adjusted according to actual design requirements. If W1≤1 / 3W, when the slab compresses the knives under the edge of the slab, the adjacent knives are easily warped, the clamping structure between the adjacent knives is not stable enough and is easily separated, which causes scratches on the surface of the slab.

[0030] In some embodiments, in order to design the structure of the blade 2 and simplify the processing difficulty, and facilitate the error-proofing when assembling with the elastic knife seat 1, as shown in Figure 4 , the cross-sectional shape of the A-A cross section of the middle line of the blade 2 in the third direction Z is an isosceles trapezoid. In some embodiments, in order to facilitate the design of the structure of the blade 2, refer to Figure 2 , Figure 5 , the B-B cross section of the blade 2 in the first direction X is a center-symmetric figure. In this embodiment, the B-B cross section of the blade 2 in the first direction X is a Z-shaped cross section. Further, in order to facilitate the clamping of the adjacent blades 2 in the first direction X, the edges of the first step surface 21 and the second step surface 22 are chamfered.

[0032] When the surface of the sawtooth-shaped blade edge is worn by more than 3mm, the scraping tool needs to be replaced in time, otherwise the deburring effect will be affected, therefore, in some embodiments, in order to improve the structural strength of the sawtooth-shaped blade edge 23 and the overall service life of the blade 2, the sawtooth-shaped blade edge 23 is made of special alloy steel, and specifically, a nickel alloy plating layer is sprayed on the surface of the sawtooth-shaped blade edge 23 by using the ultrasonic flame technology, and the thickness of the nickel alloy plating layer is 0.5mm-1mm. The bonding strength between the nickel alloy plating layer and the blade 2 is high, which can improve the wear resistance and corrosion resistance of the scraping tool and significantly improve the overall service life of the blade 2.

[0033] In the embodiment, the blade is sawtooth-shaped, high in strength, good in toughness and resistant to impact. The blade is easy to lock the irregular shape of the plate blank burr, and the deburring effect is good; a plurality of sawtooth-shaped blades 2 are combined into a wave-shaped cutting edge and installed on the deburring machine to form a certain angle with the end face of the plate blank, so that the burr is in point contact with the blade, and the deburring resistance is greatly reduced.

In step S3, the second driving mechanism 5 acts to drive the elastic knife holder 1 to reciprocate in the first direction X, so that the blade 2 removes the burr on the bottom of the slab.
