[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-Figure 4 As shown together, the hard refractory material cutting tool proposed in this embodiment can be used for cutting hard refractory materials, such as cutting carbon bricks, and can also be used for cutting stone or other cuttable plates.

[0032] The hard refractory material trimming tool comprises a base plate 1 and a tool 4 which is arranged on the upper part of the base plate 1 and can move up and down. The base plate 1 is used to place the refractory material to be cut flatly, and the tool 4 is used to cut the refractory material vertically, and the cutting surface is vertical and flat.

[0033] Specifically, support plates 2 are symmetrically arranged on both sides of the base plate 1, vertical tracks are arranged on the support plates 2, a horizontal moving rod 3 is connected between the two tracks, the moving rod 3 moves up and down along the track, and a tool 4 with a blade facing vertically downward is arranged on the moving rod 3.

[0034] A moving rod 3 is connected between the support plates 2 on both sides of the bottom plate 1, and the two ends of the moving rod 3 move in the tracks on one support plate 2. The moving rod 3 can move down smoothly, driving the cutter 4 to move down and cut into the refractory placed on the bottom plate 1.

[0035] In a specific embodiment of the present invention, the support plate 2 may be a rectangular steel plate, with two through holes provided at the lower end of the support plate 2, and the bottom plate 1 may be a rectangular wooden board, with threaded holes matching the through holes provided on both sides in the length direction of the bottom plate 1, and the threaded holes may be long nuts embedded in the sides of the bottom plate 1. The support plate 2 is fixed to the bottom plate 1 by bolts 5 passing through the through holes and the threaded holes.

[0036] The lower end of the support plate 2 is fixed to the bottom plate 1 , and the two support plates 2 are symmetrically arranged on both sides of the width of the bottom plate 1 , and the track is arranged at the part of the support plate 2 located above the bottom plate 1 .

[0037] The length and width of the bottom plate 1 and the position and height of the support plate 2 can be set according to the specific conditions of the construction. The width of the bottom plate 1 can be suitable for the width of most refractory materials. If the length is shorter than the length of the refractory material, a pad can be added at the end of the bottom plate 1 to support the refractory material.

[0038] The cutter 4 may be oriented toward the middle of the base plate 1 .

[0039] In a specific embodiment of the present invention, the track may include a guide groove 6 opened along the height direction of the support plate 2, and the guide groove 6 may be a long strip through hole opened in the portion of the support plate 2 located above the bottom plate 1. The moving rod 3 includes a double-headed screw rod, and both ends of the double-headed screw rod 31 are respectively inserted into the corresponding guide groove 6.

[0040] In order to enable the double-headed screw 31 to stably move up and down in the guide groove 6, sleeves 32 are respectively sleeved on both ends of the double-headed screw 31, and a baffle 33 is arranged on the outer periphery of one end of the sleeve 32. The sleeve 32 is inserted into the guide groove 6, and the baffle 33 is attached to the outer side of the guide groove 6. The two ends of the double-headed screw 31 are inserted into the guide groove 6 through the sleeve 32 with the baffle 33, so that the friction between the threaded part of the double-headed screw 31 and the guide groove 6 is avoided.

[0041] In order to properly fix the moving rod 3 with the guide groove 6, flange nuts 34 are tightened at both ends of the double-headed screw 31, and the flange nuts 34 are tightly attached to the baffle 33. The flange nuts 34 are properly rotated to fix the moving rod 3 horizontally between the two guide grooves 6 and prevent it from falling. However, the flange nuts 34 should not be screwed too tightly, so that it is convenient to vertically move the cutter 4 downward to cut the refractory material. The cutter 4 can be moved downward by external force, such as hitting with a hammer.

[0042] The diameter of the double-headed screw 31 can be 14 mm-20 mm, and the thicker moving rod 3 can move downward stably.

[0043] In a specific embodiment of the present invention, the width of the guide groove 6 is matched with the outer diameter of the sleeve 32 , and the outer diameter of the double-headed screw 31 is matched with the inner diameter of the sleeve 32 , so that the moving rod 3 can move stably in the guide groove 6 .

[0044] The length of the guide groove 6 and the size of the cutter 4 are set according to the specific conditions of the construction. In a specific embodiment of the present invention, the height of the cutter 4 can be 15cm-20cm and the length can be 50cm, and the length of the guide groove 6 can be about 50cm. The size of the cutter 4 and the length of the guide groove 6 can meet the one-time cutting of most refractory materials.

[0045] In a specific embodiment of the present invention, the width of the bottom plate 1 is approximately equal to the length of the cutter 4, which ensures that all refractory materials that can be placed on the bottom plate 1 can be cut at one time.

[0046] In a specific embodiment of the present invention, in order to firmly connect the moving rod 3 and the cutter 4, at least two fixing blocks 7 are fixed on the moving rod 3, and the cutter 4 is connected to the fixing blocks 7. A plurality of fixing blocks 7 are evenly arranged on the moving rod 3 to fix the cutter 4 so that the cutter 4 is firmly connected.

[0047] In order to facilitate the downward movement and cutting of the tool 4, in a specific embodiment of the present invention, the tool 4 includes a connecting plate 41 and a cutter 42 connected vertically to each other, the edge of the connecting plate 41 away from the cutter 42 is connected to the fixed block 7, and the connecting plate 41 is parallel to the moving rod 3.

[0048] The connecting plate 41 and the moving rod 3 are connected by evenly arranged fixing blocks 7. When the moving rod 3 is adjusted, the connecting plate 41 is horizontal, so that the cutter 42 is vertically downward, which is convenient for cutting a vertical incision. The connecting plate 41 can be hit with a hammer or a rubber hammer to make the cutter 42 move downward for cutting. The area of ​​the connecting plate 41 is convenient for hitting. If the connecting plate 41 is skewed during the hitting process, the moving rod 3 should be adjusted to make it horizontal.

[0049] In a specific embodiment of the present invention, in order to make the connection plate 41 firm, a reinforcing rib is provided at the connection between the connection plate 41 and the fixed block 7, and the connection plate 41 and the cutter 42 are both made of high-strength steel plates. The reinforcing rib can strengthen the connection between the connection plate 41 and the fixed block 7, and the connection plate 41 made of high-strength steel plate has strong resistance to knocking, thereby preventing the connection plate 41 from deforming during knocking. The cutter 42 made of high-strength steel plate can effectively cut hard refractory materials, has a long service life, and is not easily damaged. The blade of the cutter 42 should be sharp and durable, and the end of the high-strength steel plate should be trimmed and polished to 6 mm.

[0050] In a specific embodiment of the present invention, in order to facilitate the measurement of the cutting position of the refractory material, a scale 8 is provided on the side of the base plate 1 where the support plate 2 is installed. After the refractory material is placed on the base plate 1, the length of the refractory material to be cut is measured by the scale 8, so as to facilitate the determination of the relative position of the refractory material and the cutter 42.

[0051] As described above, the hard refractory material trimming tool according to the present invention is described by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various improvements can be made to the hard refractory material trimming tool proposed by the present invention without departing from the content of the present invention. Therefore, the protection scope of the present invention should be determined by the content of the attached claims.
