It has excellent cutting performance on alloy steel, stainless steel and other difficult-to-cut materials. The resin cutting disc is widely used in cutting operations of various materials due to its light weight, high cutting efficiency and low noise.

[0003] A high-heat-dissipation explosion-proof resin cutting disc is disclosed in Chinese patent No. 202421757251.X, which relates to the technical field of resin cutting disc.

An axle sleeve is fixedly connected inside the axle hole. A cavity is arranged inside the cutting disc, and a heat dissipation assembly for improving the heat dissipation efficiency of the cutting disc is arranged inside the cavity. A polishing assembly for polishing workpieces is arranged on both sides of the cutting disc. The heat dissipation assembly comprises a metal heat-conducting disc fixedly connected inside the cavity. A heat dissipation hole is formed on the surface of the cutting disc, and a heat-conducting column is fixedly connected inside the heat dissipation hole and in contact with the metal heat-conducting disc. However, during use, a large amount of cutting debris will accumulate in the cutting gap and be difficult to discharge, which will increase the resistance of the cutting disc, affect the heat dissipation and cutting efficiency, and accelerate the wear of the cutting disc due to the falling of the abrasive on the cutting disc, thereby affecting the service life.

[0004] In addition, the explosion-proof performance is poor, and the cutting disc is prone to cracking or even breaking during high-speed cutting or impact by hard points, which not only affects the normal progress of the cutting operation, but also may cause safety hazards such as flying debris, threatening the personal safety of the operator. In addition, the cutting disc is prone to jamming during cutting, and the cutting machine will continue to apply torque at the moment of jamming, which is easy to cause the cutting disc to crack, the debris to scatter, and thus affect the personal safety and cause damage to the cutting equipment.

[0021] Please refer to Figures 1-5 The present application provides a technical solution: a wear-resistant and explosion-proof resin cutting piece, comprising a cutting piece body 1, a center hole is formed at the center position of the cutting piece body 1, a reinforcing ring 101 is embedded in the center hole, the longitudinal section of the reinforcing ring 101 is in a U-shaped structure, a protection assembly 3 is arranged on the cutting piece body 1, the protection assembly 3 is used for protecting the cutting piece body 1, a mounting assembly 2 is arranged on the reinforcing ring 101, the mounting assembly 2 is used for mounting the cutting piece body 1 on a cutting machine rotor, and a positioning assembly 4 is arranged on the mounting assembly 2, the positioning assembly 4 is used for connecting and positioning between the reinforcing ring 101 and an annular seat 202.

[0022] The mounting assembly 2 comprises a mounting ring 201 and a compression ring 204, the inner side of the mounting ring 201 is provided with the annular seat 202, the side surface of the annular seat 202 is provided with a threaded hole 203, the outer circumferential surface of the annular seat 202 is attached to the inner circumferential surface of the reinforcing ring 101, and the compression ring 204 is located at the side of the cutting piece body 1 away from the mounting ring 201 and corresponds to the position of the annular seat 202. The reinforcing ring 101 is preferably made of metal material, the arrangement of the reinforcing ring 101 effectively improves the strength of the center hole of the cutting piece body 1, and effectively prevents the center position of the cutting piece body 1 from cracking.

[0023] The inner side of the compression ring 204 corresponds to the elastic pad 205, and the elastic pad 205 corresponds to the annular seat 202. The elastic pad 205 is made of rubber material. The elastic pad 205 is arranged to realize the elastic contact between the compression ring 204 and the annular seat 202, and to realize the slight floating of the compression ring 204 relative to the annular seat 202.

[0024] The side surface of the compression ring 204 is penetrated by the screws 206 in a ring array. The screws 206 are countersunk screws. The screws 206 are screwed with the threaded holes 203 through the threads formed at the end portions. The screws 206 are selected to be countersunk screws, so that the outer ends of the screws 206 are flush with the side surface of the compression ring 204 or even do not protrude from the side surface of the compression ring 204, thereby ensuring the tightness of the fit between the side surface of the compression ring 204 and the rotor of the cutting equipment.

[0025] Specifically, the reinforcing ring 101 and the cutting blade body 1 are designed to be integrally formed. The mounting ring 201 and the compression ring 204 are respectively located on the two sides of the cutting blade body 1. The annular seat 202 is matched with the inner circumferential surface of the reinforcing ring 101. The end portion of the annular seat 202 is flush with the other side of the reinforcing ring 101. Then, the compression ring 204 is matched with the annular seat 202, so that the elastic pad 205 is fitted with the end surface of the annular seat 202. At the same time, the screws 206 are matched with the threaded holes 203. By rotating and tightening the screws 206, the connection between the compression ring 204 and the annular seat 202 can be realized.

[0026] The mounting assembly 2 further comprises limiting teeth 207 and tooth grooves 208. The limiting teeth 207 are arranged in a ring array on the inner side of the compression ring 204. The tooth grooves 208 are formed in a ring array on the side surface of the reinforcing ring 101. The limiting teeth 207 are made of soft metal material. The limiting teeth 207 and the tooth grooves 208 are matched.

[0027] Specifically, after the compression ring 204 is fitted with the end surface of the annular seat 202, the limiting teeth 207 are engaged with the tooth grooves 208, thereby realizing the circumferential limiting between the compression ring 204 and the reinforcing ring 101. In the extreme case and under the high torque of the cutting machine, the limiting teeth 207 are deformed by being pressed by the tooth grooves 208, so that the limiting teeth 207 are separated from the limiting of the tooth grooves 208. The mounting assembly 2 is rotated alone, and does not drive the cutting blade body 1 to rotate.

[0028] The mounting assembly 2 further comprises a limiting ring 210 and an annular groove 211. The limiting ring 210 is arranged on the inner side of the mounting ring 201. The annular groove 211 is formed on the side surface of the reinforcing ring 101. The limiting ring 210 and the annular groove 211 are slidably matched.

[0029] Specifically, the limiting ring 210 is matched with the annular groove 211, thereby realizing the rotational connection between the mounting ring 201 and the reinforcing ring 101.

[0030] The protection assembly 3 comprises notches 301 and flow guide grooves 303, the notches 301 are annularly arranged on the circumferential surface of the cutting blade body 1, the notches 301 are V-shaped structures, and the sharp end of the notches 301 close to the center of the cutting blade body 1 is provided with an arc-shaped groove 302.

[0031] The flow guide grooves 303 are annularly arranged on the side surface of the cutting blade body 1, and the flow guide grooves 303 are arc-shaped structures.

[0032] Specifically, the notches 301 are used to accommodate material debris generated by cutting, and the arc-shaped cutting edges are arranged in an interval array between the notches 301, so that when the cutting blade body 1 is overloaded, the arc-shaped cutting edges serve as the final energy release site to control ablation when overload occurs, thereby avoiding the overall penetration explosion of the cutting blade body 1, and the arc-shaped groove 302 is arranged in an arc-shaped structure to prevent debris from being blocked in the inner end of the notch 301 and being difficult to discharge.

[0033] The flow guide grooves 303 are arranged in an arc-shaped structure to form a pressure difference driven radial airflow when the cutting blade body 1 rotates, promote cutting seam ventilation and dust discharge, and inhibit heat accumulation.

[0034] The protection assembly 3 further comprises an elastic sheet 305, the elastic sheet 305 is arranged at one end of the flow guide groove 303 close to the center of the cutting blade body 1, the elastic sheet 305 is arranged in an arc-shaped structure and protrudes outward of the cutting blade body 1, and the end of the elastic sheet 305 away from the flow guide groove 303 abuts against the pressure ring 204.

[0035] Specifically, the elastic sheet 305 is outwardly arc-shaped protruded after being elastically extruded after being connected with the rotor of the cutting device, and the elastic sheet 305 is radially limited relative to the rotor of the cutting device under the action of the reverse elastic force of the elastic sheet 305, thereby limiting the radial runout of the cutting blade body 1.

[0036] The positioning assembly 4 comprises movable grooves 401, the movable grooves 401 are annularly arranged in the inner part of the annular seat 202, the movable grooves 401 movably penetrate the positioning columns 402 on one side close to the inner wall of the annular seat 202, and the positioning columns 402 and the inner wall of the movable grooves 401 are provided with elastic members 404, and the elastic members 404 are preferably springs.

[0037] The positioning assembly 4 further comprises positioning holes 405, the positioning holes 405 are annularly arranged on the inner wall of the reinforcing ring 101, and the positioning holes 405 are correspondingly matched with the positioning columns 402.

[0038] Specifically, when the cutting blade body 1 is in high-speed idle, the positioning columns 402 arranged in an annular array are elongated in the outer circumferential direction of the annular seat 202 under the action of centrifugal force, and the elastic members 404 are elastically stretched, so that the positioning columns 402 are inserted into the corresponding positioning holes 405 in a corresponding fit, thereby achieving the limiting of the annular seat 202 and the reinforcing ring 101 in the circumferential direction, and providing main support for the high-speed rotation cutting of the cutting blade body 1.

[0039] In use, the cutting blade body 1 is first installed on the cutting device, the annular seat 202 is sleeved on the rotor, and the compression ring 204 is located on the inner side. The installation ring 201 is pushed to move to the inner side of the rotor by using the fastener at the outer end of the rotor, so that the compression ring 204 tightly abuts against the inner side of the rotor to fix the cutting blade body 1. Then the cutting device is started. Since the limiting teeth 207 and the tooth grooves 208 are engaged at this time, the cutting device will make the cutting blade body 1 rotate at high speed under the action of the cooperation of the limiting teeth 207 and the tooth grooves 208. At the same time, the positioning columns 402 are elongated under the action of centrifugal force, so that the positioning columns 402 cooperate with the positioning holes 405, and the elastic members 404 are stretched. After the positioning columns 402 are inserted into the positioning holes 405 inside the reinforcing ring 101, the cutting blade body 1 is supported by the positioning columns 402, so that the cutting blade body 1 rotating at high speed slowly contacts the material to be cut to perform cutting work.

[0040] During the cutting process, the cutting debris generated will first gather in the notches 301, preventing too much cutting debris from gathering in the cutting gap to increase the rotation resistance of the cutting blade body 1, thereby improving the cutting efficiency. At the same time, the abrasives falling off the cutting blade body 1 will move along the circumference of the cutting blade body 1 and enter the flow guide grooves 303, preventing the abrasives from rubbing against the side surface of the cutting blade body 1 and affecting the service life of the cutting blade body 1.

[0041] After a long time of cutting, when too much cutting debris gathers in the notches 301, it will increase the rotation resistance and heat generation of the cutting blade body 1, and will affect the circulation of the airflow in the flow guide grooves 303 and the discharge of the cutting debris in the cutting gap.

[0042] Therefore, the protection assembly 3 further comprises a containing groove 304, which is annularly arranged through the side surface of the cutting blade body 1. The containing groove 304 is arranged in an arc shape, and the two ends of the containing groove 304 are respectively communicated with the two adjacent flow guide grooves 303.

[0043] The containing groove 304 is used to contain the debris particles, and when a micro-crack is generated at the center or the circumferential edge of the cutting blade body 1, the crack is blocked after extending to the containing groove 304, thereby avoiding the crack from continuing to spread.

[0044] The end of the flow guide groove 303 away from the center of the cutting blade body 1 is communicated with the arc-shaped groove 302.

[0045] When in use, since the end of the flow guide groove 303 is in communication with the arc-shaped groove 302, and the containing groove 304 is in communication with the flow guide groove 303, when the cutting debris in the recess 301 is accumulated, the cutting debris will enter the flow guide groove 303 through the arc-shaped groove 302, and at the same time, under the driving of the airflow, part of the cutting debris and the fallen abrasive in the flow guide groove 303 will enter the containing groove 304, so as to realize the transfer of the cutting debris, ensure the communication of the flow guide groove 303 with the outside, and also, part of the cutting debris and the abrasive will enter the containing groove 304 during the cutting process, so as to prevent the cutting debris and the fallen abrasive from accumulating in the cutting gap and reducing the cutting efficiency.

[0046] In addition, in the process of high-speed rotation cutting of part of the prior art, when the cutting piece suddenly stops, the rotor of the cutting device will continue to apply a torsion, so as to cause the cutting piece to break or the cutting device to be damaged.

[0047] When the cutting piece body 1 is suddenly stuck in the process of high-speed rotation cutting, since the cutting piece body 1 no longer rotates, the centrifugal force generated by the rotation of the cutting piece body 1 disappears, at this time, the elastic member 404 quickly elastically resets to drive the positioning column 402 to shrink into the movable groove 401, the positioning column 402 is separated from the positioning hole 405, and when the rotor of the external cutting device continues to provide a high torsion, since the cutting piece body 1 cannot rotate, and the limiting tooth 207 is made of soft metal, under the action of the high torsion provided by the cutting device, a high extrusion force is generated between the limiting tooth 207 and the tooth groove 208, the limiting tooth 207 is extruded and deformed by the inner wall of the tooth groove 208, the limiting tooth 207 is separated from the limiting of the tooth groove 208, so that the limiting between the pressing ring 204 and the reinforcing ring 101 is completely released, the synchronous rotation of the pressing ring 204, the annular seat 202 and the mounting ring 201 is realized, so as to release the driving of the cutting piece body 1 by the high torsion of the cutting device, and prevent the cutting piece body 1 from being continuously subjected to the torsion after being stuck, so as to cause the breakage of the cutting piece body 1 or the damage of the cutting device.

[0048] It should be noted that after the limiting tooth 207 is extruded and damaged, a new pressing ring 204 only needs to be replaced, so that the normal use can be continued, and after the damaged limiting tooth 207 is completely removed, a new limiting tooth 207 is reformed at the original position of the pressing ring 204, so as to realize the reuse of the pressing ring 204 and reduce the cost.

[0049] In addition, after the cutting piece body 1 is stuck, since the temperature of the cutting piece body 1 is relatively high, and in order to protect the cutting piece body 1, the cutting piece body 1 cannot be taken out with strong force, and the cutting debris accumulated in the cutting gap will increase the friction of the cutting piece body 1, so that the taking out is difficult, therefore, the following improvement is made: The mounting assembly 2 further comprises a plurality of protrusions 209, which are arranged in an annular array on the circumferential side of the compression ring 204.

[0050] In use, after the positioning column 402 is disengaged from the positioning hole 405, the protrusions 209 rotate at high speed during the high-speed idle rotation of the compression ring 204, the annular seat 202 and the mounting ring 201. When the protrusions 209 rotate, the arc surfaces of the protrusions 209 abut against the annular array of the elastic sheets 305, and the elastic sheets 305 are deformed by being pressed. After the protrusions 209 are disengaged from the elastic sheets 305, the deformed elastic sheets 305 quickly return to their original positions. Thus, the protrusions 209 continuously deform the elastic sheets 305, and the elastic sheets 305 continuously return to their original positions, so that the elastic sheets 305 vibrate at high frequency. The high-frequency vibration of the elastic sheets 305 causes the cutting blade body 1 to vibrate at high frequency, so that the cutting blade body 1 is loosened, the cutting blade body 1 is quickly disengaged from the cutting slot, and the cutting blade body 1 is quickly removed.

[0051] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is based on the content of the specification and drawings, is also included in the patent protection scope of the present application.
