Description

Technical Field

[0001] This utility model relates to the technical field of glass tempering furnaces, specifically to a cutting tool for heat insulation cotton in tempering furnaces. Background Technology

[0002] The side wall of the glass tempering furnace is equipped with an insulation layer, which is usually composed of multiple layers of ceramic fiber insulation cotton. After the multiple layers of insulation cotton are stacked, roller holes for insulation of ceramic rollers are installed. The roller holes can be easily maintained and replaced if they are worn or damaged by collision with the ceramic rollers. During the initial processing, the surface of the joint between the insulation cotton and the roller holes needs to be trimmed by the insulation cotton cutting tool to make it flat and meet the installation requirements of the roller holes.

[0003] Utility model patent CN217703606U discloses a cutting fixture for tempering furnace insulation cotton, which includes the following cutting tool: The tool comprises a tool body and multiple blades. The tool body has multiple mounting slots, the number of which is the same as the number of blades. Each mounting slot has a positioning protrusion, and each blade has a positioning groove. When the blade is mounted on the tool body, the positioning protrusion and the positioning groove cooperate. The blade can be replaced after wear. The cutting tool requires positioning via the positioning protrusion and positioning groove during installation to ensure the accuracy of the blade after installation, which increases the installation time. During machining, the positioning protrusion needs to be machined inside the mounting slot, and the positioning groove needs to be machined on the blade, further increasing the machining difficulty and time. Summary of the Invention

[0004] This utility model provides a cutting tool for heat insulation cotton in tempering furnaces, in order to solve the problems mentioned in the background art, such as high tool processing difficulty, long processing time, and troublesome installation.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0006] A cutting tool for insulating cotton in a tempering furnace includes a tool holder and a blade. The blade is uniformly fixed on the tool holder. The tool holder includes a pair of parallel circular bases. Fixing seats are uniformly arranged on the outer ring of the circular bases. The fixing seats are provided with fixing grooves. The top of the fixing seats is provided with through screw holes. Fixing nuts are provided in the screw holes. The blades are installed in the fixing grooves, and the inner end of the blades is in close contact with the inner end of the fixing grooves. The fixing nuts press the blades tightly through the screw holes.

[0007] Preferably, the blade is elongated and has a cutting head at one end, the cutting head having an inclined cut surface.

[0008] Preferably, the tool holder further includes an expansion sleeve and a bushing. The expansion sleeve is installed in a fixing hole in the middle of the disc base, and the two expansion sleeves are fixedly connected by the bushing.

[0009] Preferably, the expansion sleeve includes an expansion outer sleeve and an expansion inner sleeve, with a clamping groove between the expansion outer sleeve and the expansion inner sleeve. The fixing hole of the disc base is embedded in the clamping groove, and the expansion outer sleeve is fixed to the expansion inner sleeve by bolts.

[0010] Preferably, the bushing has connectors at both ends, and the connectors are fixedly connected to the expansion inner sleeve.

[0011] Preferably, the tool holder also includes several fixing rods, and the disc base is provided with connecting holes for cooperating with the fixing rods. The two ends of the fixing rods are respectively connected to the connecting holes on the two disc bases.

[0012] Preferably, the tool holder further includes at least one intermediate disk, the structure of which is the same as that of the disk base, and the intermediate disk is fixed to the bushing and the fixing rod.

[0013] Preferably, the disc base is provided with an arc-shaped through hole.

[0014] Preferably, the fixing groove is tilted at a certain angle so that the blade maintains a certain angle with the horizontal plane after installation.

[0015] This utility model has the following beneficial effects:

[0016] The original design of positioning and installing the cutting tool through positioning protrusions and positioning grooves has been eliminated. Instead, positioning and installation are achieved by the inner end of the blade fitting tightly against the inner end of the fixing groove. Positioning is more convenient and faster, while ensuring the accuracy of the blade.

[0017] No further machining of positioning protrusions is required in the tool mounting slot, and no positioning grooves are required on the cutting tool, which reduces the machining difficulty of the tool, reduces machining time, improves efficiency, and reduces costs. Attached Figure Description

Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figure 1-Figure 2 As shown, a cutting tool for insulating cotton in a tempering furnace includes a tool holder and blades 4. The blades 4 are uniformly fixed on the tool holder. The tool holder includes a pair of parallel circular bases 1. Fixing seats 5 are uniformly arranged on the outer ring of the circular bases 1. Each fixing seat 5 has a fixing groove 9 and a through screw hole 10 at its top. A fixing nut 6 is installed in the screw hole 10. The blades 4 are installed in the fixing grooves 9, with the inner end of the blades 4 tightly attached to the inner end of the fixing grooves 9. The fixing nut 6 presses the blades 4 tightly through the screw hole 10. The tool holder also includes an expansion sleeve 3 and a bushing 11. The expansion sleeve 3 is installed in a fixing hole 8 in the middle of the circular base 1, and the two expansion sleeves 3 are fixedly connected by the bushing 11.

[0027] The tool holder also includes several fixing rods 12. The disc base 1 is provided with connecting holes 2 for cooperating with the fixing rods. The two ends of the fixing rods 12 are respectively connected to the connecting holes 2 on two disc bases 1. Three to four fixing rods 12 can be provided, evenly distributed on the disc base 1, to increase the stability of the tool holder.

[0028] The tool holder also includes at least one intermediate plate, the structure of which is the same as that of the disc base 1. The intermediate plate is fixed on the bushing 11 and the fixing rod 12. The intermediate plate can be set according to the length of the blade 4 to increase the force on the middle part of the blade 4 and increase the stability of the tool.

[0029] The disc base 1 is provided with an arc-shaped through hole 7, which can be spaced apart from the connecting hole 2, which is beneficial for heat dissipation of the cutting tool.

[0030] like Figure 3 As shown, the expansion sleeve 3 includes an expansion outer sleeve 301 and an expansion inner sleeve 302. A clamping groove 303 is provided between the expansion outer sleeve 301 and the expansion inner sleeve 302. The fixing hole 8 of the disc base 1 is embedded in the clamping groove 303. The expansion outer sleeve 301 is fixed to the expansion inner sleeve 302 by bolts 304.

[0031] like Figure 4As shown, the bushing 11 has connectors 1101 at both ends, and the connectors 1101 are fixedly connected to the expansion inner sleeve 302.

[0032] like Figure 5 As shown, the blade 4 is elongated, with a cutting head 401 at one end. The cutting head has an inclined cut surface, preferably with an inclination angle of 40-60 degrees. The blade is a regular elongated shape, intersecting with the original curved blade, making processing easier and increasing strength. The cutting head also has stronger wear resistance and a longer service life.

[0033] like Figure 6 As shown, the fixing groove 8 on the fixing seat 5 is tilted at a certain angle so that the blade 4 maintains a certain angle with the horizontal plane after installation, which is more conducive to the rotation and cutting of the tool.

[0034] The above description is the preferred embodiment of this utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of this utility model, and these should also be considered as the scope of protection of this utility model in the field of tempered glass processing technology.
