Description

Technical Field

[0001] The present invention relates to the technical field of rotary cutter head cutting, and particularly to a cutting device for the shell of a stainless steel electric kettle. Background Technique

[0002] An electric kettle is a household water heater. When processing an electric kettle, a stainless steel pipe is generally cut to obtain the stainless steel shell of the electric kettle.

[0003] In the prior art, when cutting it, a cutting device is generally used, which generally consists of structures such as a motor, a rotary cutter head, a cutter head housing, and a frame. When in use, the stainless steel pipe is guided by the guiding rollers on the frame so that it can enter the cutting range, and clamping pieces are used to clamp the steel pipe to ensure clamping stability. At this time, by starting the motor, the rotary cutter head can rotate, and then by moving the cutter head housing, the rotary cutter head can be driven to cut the stainless steel pipe.

[0004] In actual use, due to the rotational movement characteristics of the rotary disk cutter, the direction of the force exerted on the stainless steel pipe by the cutter continuously changes during the cutting process. The stainless steel pipe is subjected to the extrusion and tearing action of the cutter, and burrs are easily generated at the cutting edge. Especially when cutting a relatively thick stainless steel pipe or when the cutting speed is inappropriate, the burr phenomenon is more obvious. The burrs not only affect the aesthetics of the cutting surface but also require additional processing procedures to remove, increasing the production cost and production cycle, and making the use economy relatively low. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In the present invention, abrasive papers are installed on both sides of the rotating cutter head, so that grinding can be carried out during cutting.

Detailed implementation mode

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: Please refer to Figures 1 to 13 , the present invention provides a technical solution: a cutting device for the outer shell of a stainless steel electric kettle, including a machine tool 1. The machine tool 1 is the main part of the device, and its outer shell is made of transparent material and is equipped with a cylinder clamping component for clamping and limiting the stainless steel pipe entering the interior of the machine tool 1. A guiding roller is installed inside it for pulling the movement of the stainless steel pipe. A cutter head housing 2 is slidably connected inside the machine tool 1, enabling the cutter head housing 2 to slide back and forth. A rotating shaft 8 is rotatably connected inside the cutter head housing 2, and the cutter head housing 2 provides an installation space for the rotating shaft 8. A rotating cutter disc 3 is fixedly connected to the outer middle part of the rotating shaft 8. The rotating shaft 8 is used to drive the rotating cutter disc 3 to rotate, enabling the rotating cutter disc 3 to cut the stainless steel pipe. Sandpaper sheets 4 are detachably connected to both sides of the rotating cutter disc 3. The sandpaper sheets 4 are of a multi-segment design, and their connection parts are provided with sealing strips and sealing grooves and are filled with epoxy resin, so that the connection stability and accuracy between the multiple sandpaper sheets 4 are better. The sandpaper sheets 4 are used to polish the cutting surface of the stainless steel pipe, thereby achieving the effect of deburring. A placement groove 1 is opened on one side inside the cutter head housing 2. Two communication grooves 1 are opened on the lower side of the placement groove 1. A gear 31 is rotatably connected inside the placement groove 1. The placement groove 1 plays a limiting role for the gear 31, enabling the gear 31 to rotate smoothly. When the gear 31 rotates, it can quantitatively squeeze the coolant into the interior of the communication groove 1, so that the coolant can evenly cool and lower the temperature of the cutting surface of the stainless steel pipe, and play a lubricating role, reducing the friction coefficient between the cutting tool and the material, and further improving the cutting quality and surface finish. A placement groove 2 is opened on the other side inside the cutter head housing 2. A communication groove 2 is opened on the lower inner wall of the placement groove 2. An impeller 28 is rotatably connected inside the placement groove 2. The placement groove 2 plays a limiting role for the impeller 28, enabling the impeller 28 to rotate stably. When the impeller 28 rotates, it can guide the external air into the interior of the communication groove 2 and blow it concentratedly towards the cutting part of the stainless steel pipe through the communication groove 2, so as to blow away the burrs generated by cutting, having a certain cleaning effect, and being able to cool the cutting part, making the cutting effect of the rotating cutter disc 3 better.

[0033] When the rotary cutter disc 3 is needed to cut the stainless steel pipe, the rotary shaft 8 is rotated to drive the rotary cutter disc 3 to rotate, and then the cutter disc housing 2 is moved to drive the rotary cutter disc 3 to contact the stainless steel pipe, so as to cut the stainless steel pipe. As the rotary cutter disc 3 moves, the sandpaper sheet 4 is brought into contact with the stainless steel pipe, so as to deburr the stainless steel pipe. At this time, by rotating the gear 31 and the impeller 28, the gear 31 is able to squeeze the coolant quantitatively into the interior of the connecting groove 10, so that the coolant can flow evenly onto the sandpaper sheet 4, so that the sandpaper sheet 4 is soaked, and as the rotary cutter disc 3 moves, the sandpaper sheet 4 is brought into contact with the stainless steel pipe, so as to deburr the stainless steel pipe. The rotation of the disc 3 allows the coolant to be evenly distributed on the outside of the rotating cutter disc 3, and the impeller 28 can guide the external air to the inside of the connecting groove 2 12. Since the connecting groove 2 12 is small in size, the wind pressure is large, so that the debris at the cutting point of the rotating cutter disc 3 and the stainless steel pipe can be blown away, so that the debris will not adhere to the cutting point of the rotating cutter disc 3 and the stainless steel pipe. With the cooperation of the coolant and the flowing wind, the temperature at the cutting point is low, and the deformation of the rotating cutter disc 3 and the stainless steel pipe is small, so that less burrs are generated, thereby making the cutting quality better, so that the time for subsequent secondary processing is greatly reduced, thereby making the use economy higher.

[0034] Embodiment 2: On the basis of embodiment 1, in order to realize the convenient replacement of the sandpaper sheet 4, installation grooves 5 are provided on the left and right sides of the rotating cutter disc 3, and the sandpaper sheet 4 is slidably connected inside the installation grooves 5. The installation grooves 5 provide installation space for the sandpaper sheet 4, and the inner wall of the installation grooves 5 is provided with a plurality of slots 6. The inner wall of the slots 6 is plugged with an insert block 7, so that the insert block 7 can be connected to the rotating cutter disc 3, and the other end of the insert block 7 is fixedly connected to the sandpaper sheet 4, so that the insert block 7 can be installed on the rotating cutter disc 3.

[0035] When the rotary cutter disc 3 needs to be installed, the sandpaper sheet 4 is slid into the inner wall of the installation groove 5, so that the plug block 7 can slide into the interior of the slot 6 and be squeezed by the slot 6 to produce deformation, and then when the installation groove 5 fits the inner wall of the sandpaper sheet 4, the slot 6 can be reset, so that the slot 6 can be filled in the interior of the plug block 7, and then the sandpaper sheet 4 can be limited, so that the sandpaper sheet 4 can be installed on the rotary cutter disc 3. When the worn sandpaper sheet 4 needs to be disassembled, the corresponding organic solvent is selected according to the type of epoxy resin. It is applied to the epoxy resin to soften or decompose it, so that it is separated from the sandpaper, and then the sandpaper sheet 4 is deducted, so that the sandpaper sheet 4 can drive the plug block 7 to detach from the interior of the slot 6, so that the sandpaper sheet 4 can be disassembled, and then the rotary cutter disc 3 is rotated to make another sandpaper sheet 4 rotate out from the inside of the cutter disc housing 2. Repeat the above actions to disassemble multiple sandpaper sheets 4 in sequence.

[0036] Embodiment 3: On the basis of Embodiment 2, in order to achieve the synchronous rotation of the gear 31 and the impeller 28, two limiting grooves 29 are provided on the outer part of the rotating shaft 8. A second pulley 15 is rotatably connected inside the limiting groove 29. The limiting groove 29 serves as the installation space for the second pulley 15. The second pulley 15 is connected to a first pulley 13 through a belt 14, so that the second pulley 15 can drive the first pulley 13 to rotate through the belt 14. The belt 14 is slidably connected inside the cutter head housing 2, and the cutter head housing 2 plays a role in limiting the belt 14, enabling the belt 14 to move stably. One of the first pulleys 13 is fixedly connected to the gear 31, and the other first pulley 13 is fixedly connected to the impeller 28, so that the two first pulleys 13 can drive the gear 31 and the impeller 28 to rotate respectively. The two first pulleys 13 are respectively rotatably connected inside the first placement groove 9 and the second placement groove 11. The first placement groove 9 and the second placement groove 11 play a role in limiting the first pulley 13, so that the first pulley 13 will not shift during rotation.

[0037] When it is necessary to rotate the gear 31 and the impeller 28, by rotating the second pulley 15, the second pulley 15 can drive the belt 14 to rotate, the belt 14 can drive the first pulley 13 to rotate, and then the two first pulleys 13 can drive the gear 31 and the impeller 28 to rotate respectively.

[0038] Embodiment 4: On the basis of Embodiment 3, in order to achieve the selective use of the gear 31 and the impeller 28, two clamping grooves 16 are provided on the inner side of the second pulley 15. A clamping block 17 is clamped inside the clamping groove 16. A connecting shaft 18 is slidably connected to the outside of the clamping block 17. A motor is installed on the side of the connecting shaft 18 away from the first placement groove 9, so that the connecting shaft 18 can be driven by the motor to rotate. The clamping block 17 is slidably connected to the rotating shaft 8, so that the connecting shaft 18 can drive the first placement groove 9 and the second pulley 15 to rotate through the clamping block 17. Two limiting blocks 30 are fixedly connected to the outside of the connecting shaft 18. The connecting shaft 18 and the limiting blocks 30 are both slidably connected inside the rotating shaft 8, so that the connecting shaft 18 can drive the first placement groove 9 to rotate through the limiting blocks 30, and the connecting shaft 18 can be disassembled, so that the cutter head housing 2, the rotating cutter head 3 and other structures can be maintained and replaced.

[0039] When it is not necessary to drive the second pulley 15 to rotate, by sliding the clamping block 17 into the inside of the connecting shaft 18, the connecting shaft 18 can be separated from the second pulley 15 and the rotating shaft 8, and then the connecting shaft 18 can drive the first placement groove 9 to rotate through the limiting blocks 30, so that the first placement groove 9 will not drive the second pulley 15 to rotate. When it is necessary to rotate the second pulley 15, by moving the clamping block 17 outward, the clamping block 17 can penetrate through the rotating shaft 8 and be engaged with the inside of the clamping groove 16. Then when the connecting shaft 18 rotates, the connecting shaft 18 can drive the second pulley 15 and the rotating shaft 8 to rotate through the clamping block 17, and then the second pulley 15 can rotate synchronously with the rotating cutter head 3.

[0040] Example 5: On the basis of Example 4, in order to facilitate pulling the clamping block 17, a plurality of sliding grooves 19 are provided inside the connecting shaft 18. A sliding piece 20 is fixedly connected to the side of the clamping block 17 away from the clamping groove 16. The sliding piece 20 is slidably connected inside the sliding groove 19. The sliding groove 19 plays a limiting role on the sliding piece 20, so that the sliding piece 20 will not deviate when sliding. The other end of the sliding piece 20 is fixedly connected to a pull rope 21. The pull rope 21 is slidably connected inside the sliding groove 19. The sliding groove 19 plays a limiting role on the pull rope 21, so that the pull rope 21 can slide smoothly. An elastic member 22 is sleeved outside the pull rope 21. One end of the elastic member 22 is fixedly connected to the inner wall of the sliding groove 19, and the other end of the elastic member 22 is fixedly connected to the sliding piece 20.

[0041] When it is necessary to move the clamping block 17, by pulling the pull rope 21, the pull rope 21 can drive the sliding piece 20 to move inwards, and then the sliding piece 20 can drive the clamping block 17 to move inwards, and the sliding piece 20 can squeeze the elastic member 22 to deform. On the contrary, by releasing the pull rope 21, the elastic member 22 can perform a reset movement, and then the elastic member 22 can push the sliding piece 20 to move outwards, so that the sliding piece 20 can push the clamping block 17 to penetrate through the rotating shaft 8 and engage with the inside of the clamping groove 16.

[0042] Example 6: On the basis of Example 5, in order to facilitate pulling the pull rope 21 and make the clamping block 17 stably engaged inside the clamping groove 16, a pull rod 23 is slidably connected inside the connecting shaft 18. The connecting shaft 18 provides an installation space for the pull rod 23, so that the pull rod 23 can slide smoothly. Two fixing grooves 24 are provided on both the front and rear sides of the pull rod 23. The end of the pull rope 21 away from the sliding piece 20 is fixedly connected to the fixing groove 24, so that the pull rod 23 can pull the pull rope 21 to move through the fixing groove 24. Two buckling grooves 25 are provided on the right part of the pull rod 23. A blocking block 26 is sleeved on the right side of the pull rod 23. Two convex blocks 27 are fixedly connected to the inner side of the blocking block 26. The inside of the buckling groove 25 is engaged with the inside of the convex block 27, so that the blocking block 26 can drive the pull rod 23 to slide through the buckling groove 25.

[0043] When it is necessary to pull the pull rope 21, by pulling the blocking block 26, the blocking block 26 can drive the convex block 27 to slide on the outside of the pull rod 23. When the convex block 27 moves to the horizontal position of the buckling groove 25, the convex block 27 can be reset inside the buckling groove 25, so that the blocking block 26 can drive the pull rod 23 to move through the blocking block 26 and the buckling groove 25, so that the pull rod 23 can drive one end of the pull rope 21 to move through the fixing groove 24.

[0044] Example 7: On the basis of Example 6, a method for using a cutting device for the stainless steel electric kettle shell is proposed, including the following steps:

[0045] Step 1: By pulling the blocking block 26, the blocking block 26 drives the convex block 27 to slide outside the pull rod 23. When the convex block 27 moves to the horizontal position of the buckling groove 25, the convex block 27 is reset inside the buckling groove 25, so that the convex block 27 is engaged with the inside of the buckling groove 25. Then, move the blocking block 26 in the reverse direction, so that the blocking block 26 drives the pull rod 23 through the blocking block 26 and the buckling groove 25, and the pull rod 23 drives one end of the pull rope 21 to move through the fixed groove 24;

[0046] Step 2: As the pull rope 21 moves, the pull rope 21 no longer pulls the sliding piece 20, so that the elastic member 22 can perform a reset movement. Furthermore, the elastic member 22 can push the sliding piece 20 to move outward, so that the sliding piece 20 can push the clamping block 17 to penetrate through the rotating shaft 8 and engage with the inside of the clamping groove 16, so that the connecting shaft 18 is connected to the second pulley 15. Furthermore, by buckling the blocking block 26, the convex block 27 is separated from the buckling groove 25, and the blocking block 26 slides in the reverse direction, so that the blocking block 26 is embedded inside the rotating shaft 8, and thus will not affect the normal use of the rotary cutter head 3;

[0047] Step 3: Then rotate the connecting shaft 18, so that the connecting shaft 18 drives the second pulley 15 and the rotating shaft 8 to rotate through the clamping block 17, and the connecting shaft 18 drives the rotating shaft 8 to rotate, so that the second pulley 15 rotates synchronously with the rotary cutter head 3. At this time, the second pulley 15 drives the belt 14 to rotate, so that the belt 14 drives the first pulley 13 to rotate. Furthermore, the two first pulleys 13 drive the gear 31 and the impeller 28 to rotate respectively;

[0048] Step 4: As the gear 31 and the impeller 28 rotate, the gear 31 quantitatively extrudes the coolant into the first connecting groove 10, so that the coolant evenly flows onto the sandpaper sheet 4, so that the sandpaper sheet 4 is wetted. As the rotary cutter head 3 rotates, the outside of the rotary cutter head 3 is evenly distributed with the coolant, and the impeller 28 guides the outside air into the second connecting groove 12. Since the size of the second connecting groove 12 is small, the wind pressure is large, so that the debris at the cutting part of the rotary cutter head 3 and the stainless steel pipe can be blown, so that the debris will not adhere to the cutting part of the rotary cutter head 3 and the stainless steel pipe. With the cooperation of the coolant and the flowing air, the temperature of the cutting part is low, so that the deformation of the rotary cutter head 3 and the stainless steel pipe is small, less burrs are generated, so that the cutting quality is good, and the time for subsequent secondary processing is greatly reduced, so that the use economy is high.

[0049] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
