[0020] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 The present invention provides a bolt production cutting device 100, which is used to cut a metal round rod 200 so that the cut metal round rod 200 can be processed into a bolt. The bolt production cutting device 100 includes a body 10, a translation mechanism (not shown in the figure), a circular saw blade 11, a motor 22 and a clamping mechanism 12.
[0021] The body 10 is the main structure of the bolt production and cutting device 100. The translation mechanism is arranged on the body 10 and is used for horizontal movement along the specified direction X. For example, the translation mechanism can be a structure such as an oil cylinder, a pneumatic cylinder, an electric push rod, an electric slide rail, etc., and the specific type of the translation mechanism is not limited. The circular saw blade 11 is roughly circular, and the circular saw blade 11 is connected to the translation mechanism and can be driven by the translation mechanism to move horizontally along the specified direction X. The motor 22 is connected to the circular saw blade 11, and the motor 22 is used to drive the circular saw blade 11 to rotate to cut the metal round rod 200. The holding mechanism 12 is arranged opposite to the circular saw blade 11, and the holding mechanism 12 is used to fix the metal round rod 200 so that the circular saw blade 11 can cut the metal round rod 200.
[0022] The clamping mechanism 12 includes a base 121 , a support plate 122 , a limiting plate 123 , a clamping plate 124 , a first telescopic member 125 and a push plate 126 .
[0023] The base 121 is roughly in the shape of a flat plate. The support plate 122 is roughly in the shape of a plate, and the support plate 122 is arranged on the base 121, and the support plate 122 is used to support the metal round rod 200. The limiting plate 123 is roughly in the shape of a plate, and the limiting plate 123 is arranged on the support plate 122 and is located at one end of the support plate 122 close to the circular saw blade 11. The limiting plate 123 and the support plate 122 are perpendicular to each other, and the length direction of the limiting plate 123 and the metal round rod 200 are parallel to each other, and the limiting plate 123 is used to cooperate with the clamping plate 124 to clamp and fix the metal round rod 200 together. The clamping plate 124 is roughly in the shape of a plate, and the clamping plate 124 can be movably arranged on the support plate 122, and the clamping plate 124 and the limiting plate 123 are respectively located on both sides of the metal round rod 200. The holding plate 124 is perpendicular to the support plate 122 and the limiting plate 123. The holding plate 124 is used to cooperate with the limiting plate 123 under the push of the first telescopic member 125 to jointly clamp and fix the metal round rod 200. The holding plate 124 is provided with a receiving groove 1241 for inserting the circular saw blade 11. When the translation mechanism drives the circular saw blade 11 to cut the metal round rod 200, at least part of the structure of the circular saw blade 11 will move into the receiving groove 1241. The first telescopic member 125 is arranged on the base 121 and connected to the holding plate 124. The first telescopic member 125 is used to drive the holding plate 124 to move horizontally along the specified direction X. The first telescopic member 125 can be any structure such as an oil cylinder, an air cylinder, an electric push rod, etc., and the specific type of the first telescopic member 125 is not limited. The push plate 126 is generally plate-shaped and is disposed on the support plate 122 and in the receiving groove 1241. The push plate 126 fits the inner wall of the receiving groove 1241. When the first telescopic member 125 drives the holding plate 124 to move away from the circular saw blade 11, the push plate 126 can be moved out of the receiving groove 1241.
[0024] The operating process of the staff using the above-mentioned bolt production cutting device 100 to cut the metal round rod 200 is roughly as follows: first, the metal round rod 200 is placed on the support plate 122, and the length direction of the metal round rod 200 is ensured to be parallel to the axial direction of the circular saw blade 11, and then the first telescopic member 125 is started to drive the clamping plate 124 to move toward the direction close to the circular saw blade 11. At this time, the clamping plate 124 and the limit plate 123 can jointly clamp and fix the metal round rod 200, and then the translation mechanism and the motor 22 are started. The translation mechanism drives the high-speed rotating circular saw blade 11 to move toward the direction close to the clamping plate 124. When the circular saw blade 11 contacts the metal round rod 200, the metal round rod 200 can be cut. During the process of the circular saw blade 11 cutting the metal round rod 200, part of the structure of the circular saw blade 11 will be inserted into the receiving groove 1241 provided on the holding plate 124, and the debris generated by the cutting will also fall into the receiving groove 1241. After the cutting operation is completed, the first telescopic member 125 drives the holding plate 124 to move away from the circular saw blade 11, so that the push plate 126 will move relative to the holding plate 124 towards the direction close to the circular saw blade 11, until the push plate 126 finally moves out of the receiving groove 1241. In the above process, the push plate 126 can push the debris in the receiving groove 1241 out of the receiving groove 1241, so that the debris in the receiving groove 1241 is discharged from the receiving groove 1241 as much as possible, so as to realize the cleaning of the debris in the receiving groove 1241, thereby preventing the debris from accumulating too much in the receiving groove 1241 and affecting the cutting accuracy of the circular saw blade 11 and causing damage to the circular saw blade 11. In summary, the bolt production cutting device 100 can facilitate the staff to clean up the debris accumulated in the clamping mechanism 12, thereby ensuring the cutting accuracy of the circular saw blade 11 and protecting the safety of the circular saw blade 11. The bolt production cutting device 100 has the beneficial effects of convenient debris cleaning, high cutting accuracy, and long service life.
[0025] In some embodiments, the clamping mechanism 12 also includes a clamping plate 127 and a second telescopic member (not shown in the figure). The clamping plate 127 is roughly plate-shaped, and the clamping plate 127 is located above the support plate 122. The clamping plate 127 and the support plate 122 are spaced apart and perpendicular to each other. The second telescopic member is disposed on the base 121 and connected to the clamping plate 127. The second telescopic member is used to drive the clamping plate 127 to move in the vertical direction. The second telescopic member can be any structure such as an oil cylinder, an air cylinder, an electric push rod, etc., and the specific type of the second telescopic member is not limited. The clamping plate 127 is used to press the metal round rod 200 onto the support plate 122 under the drive of the second telescopic member.
[0026] Through the above-mentioned settings, the clamping plate 127 cooperates with the support plate 122 to limit the metal round rod 200 in the vertical direction, and the clamping plate 124 and the limiting plate 123 can limit the metal round rod 200 in the horizontal direction. Therefore, the clamping plate 127 can further improve the fixing effect of the clamping mechanism 12 on the metal round rod 200, thereby further improving the stability and reliability of the circular saw blade 11 when cutting the metal round rod 200.
[0027] See also Figures 3 to 7 In some embodiments, a circular arc surface 1261 is provided on the side of the push plate 126 facing the circular saw blade 11, and the center of the circle where the circular arc surface 1261 is located is set at the same height as the center of the circular saw blade 11. When the circular saw blade 11 moves until its own center coincides with the center of the circle where the circular arc surface 1261 is located, the distance from the circular saw blade 11 to the circular arc surface 1261 along its own radial direction is a specified distance. It should be noted that the above-mentioned "specified distance" is a critical distance value calculated in advance by the staff. When the distance from the circular saw blade 11 to the circular arc surface 1261 along its own radial direction is the above-mentioned critical distance value, it will not affect the normal rotation of the circular saw blade 11, and the distance between the circular saw blade 11 and the circular arc surface 1261 can be reduced as much as possible, so as to reduce the possibility of debris accumulation in the gap between the circular saw blade 11 and the push plate 126. Through the above-mentioned arrangement, since the arc surface 1261 is provided on the side of the push plate 126 facing the circular saw blade 11, during the process of the circular saw blade 11 cutting the metal round rod 200, the arc surface 1261 can minimize the distance between the push plate 126 and the circular saw blade 11, thereby making the gap between the push plate 126 and the circular saw blade 11 narrower, so as to reduce the amount of debris remaining between the saw blade and the push plate 126, thereby facilitating the push plate 126 to completely push out the debris in the accommodating groove 1241.
[0028] See also Figures 2 to 7 In some embodiments, the bolt production and cutting device 100 further includes a detection mechanism 13 and a control mechanism (not shown in the figure). The detection mechanism 13 includes a mounting bracket 131 and an infrared sensor 132. The mounting bracket 131 is fixedly mounted on the push plate 126, specifically on the top surface of the push plate 126. The infrared sensor 132 is disposed on the mounting bracket 131, and the infrared sensor 132 is located on the side of the arc surface 1261 facing the circular saw blade 11, and the infrared sensor 132 is a circular structure. The control mechanism is electrically connected to the infrared sensor 132 and the translation mechanism at the same time. The control mechanism can specifically be any type of electronic control device such as a single-chip microcomputer, a programmable logic controller, etc. The control mechanism is used to control the movement and stop of the translation mechanism according to the electrical signal emitted by the infrared sensor 132. When the circular saw blade 11 is inserted into the accommodating groove 1241 and moves until its center of circle coincides with the center of the circle where the arc surface 1261 is located, the circular saw blade 11 just blocks the infrared sensor 132 and just cuts off the metal round rod 200 (see Figure 7 ), the control mechanism receives the electrical signal emitted by the infrared sensor 132 and controls the translation mechanism to stop moving. It should be noted that the above “the circular saw blade 11 just blocks the infrared sensor 132 and just cuts the metal round rod 200” means that the circular saw blade 11 is inscribed in the cross section of the metal round rod 200, and the circular saw blade 11 is also inscribed in the circular contour line of the infrared sensor 132.
[0029] Through the above arrangement, when the circular saw blade 11 just cuts off the metal round rod 200, the circular saw blade 11 also just blocks the infrared sensor 132. At this time, the infrared sensor 132 can transmit an electrical signal to the control mechanism. The control mechanism controls the translation mechanism to stop moving according to the above electrical signal to avoid a safety accident caused by a small distance between the circular saw blade 11 and the arc surface 1261 of the push plate 126. Therefore, the safety and reliability of the bolt production and cutting device 100 can be improved.
[0030] See also Figures 2 to 7 In some embodiments, the bolt production and cutting device 100 further includes a guide block 14, an adjustment slider 15, a tension spring 16, a sliding push rod 17, a mounting block 18, and a positioning spring 19. The guide block 14 is fixedly disposed on the support plate 122 and is located in the receiving groove 1241. The guide block 14 is located on the side of the push plate 126 away from the circular saw blade 11. The guide block 14 is provided with an inclined surface 141, which is located on the side of the guide block 14 away from the support plate 122. The height of the side of the inclined surface 141 close to the push plate 126 is lower than the height of the side away from the push plate 126.
[0031] The adjusting slider 15 is movably arranged on the inclined surface 141 and located in the receiving groove 1241. The side of the adjusting slider 15 facing the push plate 126 is provided with an arc surface 151. It should be noted that the above-mentioned "arc surface 151" only means that the surface is a curved surface with an arc, and does not have any other meaning. The inner side wall of the receiving groove 1241 is provided with a first guide groove 1242 extending in the vertical direction, and the adjusting slider 15 is provided with a first guide block (not shown in the figure), which is movably embedded in the first guide groove 1242. The tension spring 16 is arranged horizontally, and the tension spring 16 is connected between the guide block 14 and the push plate 126, and the push plate 126 is movably arranged on the support plate 122. The surface of the push plate 126 facing the guide block 14 is provided with a second guide groove 1262 extending in the vertical direction, and one end of the sliding push rod 17 is movably embedded and clamped in the second guide groove 1262, and the other end is movably held against the arc surface 151. The mounting block 18 is a block structure, and is fixedly mounted on the top surface of the clamping plate 124. The positioning spring 19 is accommodated in the receiving groove 1241 and is arranged along the vertical direction. One end of the positioning spring 19 is connected to the mounting block 18, and the other end can be movably abutted against the sliding push rod 17. The positioning spring 19 is used to abut against the sliding push rod 17 so that the sliding push rod 17 always maintains a horizontal state and always contacts the arc surface 151. When the first telescopic member 125 drives the holding plate 124 to move away from the circular saw blade 11, the adjusting slider 15 moves along the inclined surface 141 away from the circular saw blade 11, and at the same time moves vertically upward along the first guide groove 1242. The tension spring 16 pulls the push plate 126 to move away from the circular saw blade 11. The sliding push rod 17 moves away from the circular saw blade 11, and at the same time moves vertically upward along the second guide groove 1262. The speed at which the push plate 126 moves away from the circular saw blade 11 is slower than the speed at which the holding plate 124 moves away from the circular saw blade 11, so that the push plate 126 can be moved out of the accommodating groove 1241.
[0032] With the above arrangement, when the first telescopic member 125 drives the holding plate 124 to move in a direction away from the circular saw blade 11, since the first guide block is movably embedded in the first guide groove 1242, the holding plate 124 will drive the adjusting slider 15 to move in a direction away from the circular saw blade 11 through the first guide block. Since the adjusting slider 15 is located on the inclined surface 141 of the guide block 14, the adjusting slider 15 will move in a direction away from the circular saw blade 11 while moving vertically upward along the first guide groove 1242. Due to the presence of the tension spring 16, during the movement of the adjusting slider 15 along the inclined surface 141, the tension spring 16 will always pull the push plate 126 to move in a direction away from the circular saw blade 11, so as to ensure that the end of the sliding push rod 17 close to the arc surface 151 is always in contact with the arc surface 151. During the above movement of the push plate 126, the sliding push rod 17 will move along with the push plate 126 in the direction away from the circular saw blade 11, while moving vertically upward along the second guide groove 1262 to squeeze the positioning spring 19. The elastic force of the positioning spring 19 reacts on the sliding push rod 17 to ensure that the sliding push rod 17 always maintains a horizontal state and always abuts against the curved surface 151. Due to the existence of the curved surface 151 and the fixed length of the sliding push rod 17 in the horizontal direction, during the above movement, the speed at which the push plate 126 moves away from the circular saw blade 11 is slower than the speed at which the clamping plate 124 moves away from the circular saw blade 11, so that the push plate 126 can move out of the receiving groove 1241, thereby enabling the push plate 126 to push out the debris remaining in the receiving groove 1241. And, through the above arrangement, please refer to Figure 7 and Figure 8When the bolt production and cutting device 100 is used to cut metal round rods 200 with different diameters, the clamping assembly needs to clamp the metal round rods 200 with different diameters. At this time, the first telescopic member 125 needs to drive the clamping plate 124 to move adaptively along the specified direction X to ensure that the metal round rods 200 with different diameters can be clamped by the clamping plate 124 and the limiting plate 123. Since the guide block 14 is provided with a slope 141, the adjusting slider 15 is provided with a curved surface 151, and one end of the sliding push rod 17 is always in contact with the curved surface 151, it can be ensured that no matter where the holding plate 124 moves to, the push plate 126 can move to the target position corresponding to the position of the holding plate 124. When the push plate 126 is in the above-mentioned target position, it can always be ensured that when the circular saw blade 11 is inserted into the accommodating groove 1241 and moves to a specified distance from the circular arc surface 1261, the circular saw blade 11 just blocks the infrared sensor 132 and just cuts off the metal round rod 200. At this time, the infrared sensor 132 can transmit an electrical signal to the control mechanism, and the control mechanism controls the translation mechanism to stop moving according to the above-mentioned electrical signal to avoid a safety accident caused by a small distance between the circular saw blade 11 and the circular arc surface 1261 of the push plate 126. In summary, the above arrangement enables the clamping mechanism 12 to clamp metal round rods 200 of different diameters, and when the circular saw blade 11 just cuts the metal round rod 200 (at this time, the distance between the circular saw blade 11 and the arc surface 1261 of the push plate 126 is the specified distance), the detection mechanism 13 can always transmit an electrical signal to the control mechanism, so that the control mechanism controls the translation mechanism to stop moving. It should be noted that the realization of the above technical effect requires a special design of the arc surface 151 of the adjustment slider 15 in combination with several parameters, and the above "several parameters" at least include: the slope of the inclined surface 141 of the guide block, the curvature of the arc surface 1261 of the push plate 126, and the specified distance between the circular saw blade 11 and the arc surface 1261 of the push plate 126.
[0033] See also Figure 2 and Figure 6 In some embodiments, the sliding push rod 17 includes a push rod 171, a push ball 172, and a second guide block (not shown in the figure). The push ball 172 is a spherical structure, connected to the push rod 171 and located at one end of the push rod 171 close to the adjusting slider 15, and the push ball 172 can be movably abutted against the arc surface 151. The second guide groove 1262 is a T-shaped groove, and the second guide block is connected to the push rod 171 and located at one end of the push rod 171 close to the push plate 126. The second guide block is a T-shaped block adapted to the second guide groove 1262, and the second guide block can be movably embedded in the second guide groove 1262. The end of the positioning spring 19 away from the mounting block 18 can be movably abutted against the push rod 171.
[0034] Through the above arrangement, since the second guide groove 1262 and the second guide block are in a T-shaped structure, it can be ensured that one end of the sliding push rod 17 cannot move out of the second guide groove 1262 in the horizontal direction, thereby ensuring that one end of the sliding push rod 17 is stably slidably connected to the push plate 126. Since the pushing ball 172 contacts the arc surface 151, the contact area between the sliding push rod 17 and the arc surface 151 can be reduced, thereby reducing the friction resistance between the sliding push rod 17 and the arc surface 151, so as to facilitate the relative movement of the sliding push rod 17 and the adjusting slider 15.
[0035] See also Figures 2 to 6 In some embodiments, the bolt production and cutting device 100 further includes a limiting bracket 20, which is roughly a rectangular frame. The limiting bracket 20 is fixedly arranged on the support plate 122, and is provided with a clearance groove 201, which penetrates the limiting bracket 20 along the specified direction X, and the clamping plate 124 can be movably arranged in the clearance groove 201 and fit with the inner side wall of the clearance groove 201. Through the above arrangement, the limiting bracket 20 is used to limit and guide the clamping plate 124, so that the clamping plate 124 can move stably along the specified direction X.
[0036] In some embodiments, the limiting bracket 20 includes a first mounting plate 202, a second mounting plate 203 and a connecting block 204. The first mounting plate 202 and the second mounting plate 203 are both plate-shaped, and the first mounting plate 202 and the second mounting plate 203 are both spaced apart and perpendicular to the limiting plate 123. The first mounting plate 202 and the second mounting plate 203 are both arranged on the support plate 122, and the first mounting plate 202 and the second mounting plate 203 are parallel to each other and are relatively spaced apart to form a clearance groove 201, and the connecting block 204 is connected between the first mounting plate 202 and the second mounting plate 203 and is in contact with the top surface of the holding plate 124. Through the above arrangement, the first mounting plate 202 and the second mounting plate 203 are used to limit and guide the holding plate 124 in the horizontal direction, and the connecting block 204 is used to limit the holding plate 124 in the vertical direction, so as to further improve the stability of the holding plate 124 when moving.
[0037] In some embodiments, the first mounting plate 202 and the limiting plate 123 are arranged at a relative interval, the pressing plate 127 is located between the first mounting plate 202 and the limiting plate 123, and the pressing plate 127 is simultaneously in contact with the first mounting plate 202 and the limiting plate 123. Through the above arrangement, the limiting plate 123 cooperates with the first mounting plate 202 to limit and guide the pressing plate 127, so as to ensure that the pressing plate 127 can stably move in the vertical direction, so that the pressing plate 127 can stably press the metal round rod 200 on the supporting plate 122, so as to improve the fixing effect of the metal round rod 200.
[0038] See also Figure 2 , Figure 6 and Figure 7 In some embodiments, the connection block 204 is located on the side of the mounting block 18 away from the circular saw blade 11, and the connection block 204 is arranged relative to the mounting block 18. The bolt production and cutting device 100 also includes a liquid spraying mechanism 21, which includes a telescopic accommodating cylinder 211, a liquid inlet pipe 212, a liquid outlet pipe 213, a spray head 214 and a one-way valve (not shown in the figure). The telescopic accommodating cylinder 211 is provided with a liquid storage chamber 215 inside, and the telescopic accommodating cylinder 211 includes an outer cylinder 2112 and an inner cylinder 2111 arranged coaxially. The outer cylinder 2112 and the inner cylinder 2111 are both cylindrical structures, and the outer cylinder 2112 can be movably sleeved on the outer periphery of the inner cylinder 2111, and at least part of the structure of the inner cylinder 2111 extends to the outside of the outer cylinder 2112. One end of the inner cylinder 2111 extending outside the outer cylinder 2112 is fixedly connected to the mounting block 18, and one end of the outer cylinder 2112 away from the inner cylinder 2111 is fixedly connected to the connecting block 204. One end of the liquid inlet pipe 212 is connected to the outer cylinder 2112 and communicates with the liquid storage chamber 215, and the other end of the liquid inlet pipe 212 is connected to a liquid supply device (not shown in the figure). The liquid supply device is used to transport coolant or cutting fluid into the liquid inlet pipe 212. A one-way valve is arranged in the liquid inlet pipe 212, and the conducting direction of the one-way valve is from the liquid supply device to the liquid storage chamber 215. One end of the liquid outlet pipe 213 is connected to the inner cylinder 2111 and communicates with the liquid storage chamber 215, and the other end of the liquid outlet pipe 213 is connected to the nozzle 214, and the output end of the nozzle 214 faces the arc surface 1261 of the push plate 126. It should be noted that the liquid inlet pipe 212 and the liquid outlet pipe 213 are both retractable bellows, which can be freely bent and retracted as needed to meet the use requirements in different scenarios.
[0039] Through the above arrangement, when the circular saw blade 11 cuts off the metal round rod 200, the first telescopic member 125 drives the holding plate 124 to move away from the circular saw blade 11, and the mounting block 18 moves synchronously with the holding plate 124, while the position of the connecting block 204 remains unchanged. Therefore, the mounting block 18 will drive the inner cylinder 2111 to move and insert into the outer cylinder 2112, thereby compressing the volume in the liquid storage chamber 215 to become smaller. Since a one-way valve is provided in the liquid inlet pipe 212, under the action of pressure, the liquid in the liquid storage chamber 215 will enter the liquid outlet pipe 213 and be sprayed from the nozzle 214 to the arc surface 1261, thereby flushing and discharging the debris remaining in the arc surface 1261 and the receiving groove 1241, so as to further improve the cleaning effect of the debris in the receiving groove 1241. On the contrary, when the first telescopic member 125 drives the holding plate 124 to move toward the circular saw blade 11, the mounting block 18 drives the inner cylinder 2111 to move and extend into the outer cylinder 2112, thereby increasing the volume of the liquid storage chamber 215. Under the action of pressure, the above process will suck the coolant or cutting fluid in the liquid supply device into the liquid storage chamber 215 through the liquid inlet pipe 212 to replenish the liquid in the liquid storage chamber 215. In addition, the liquid spraying mechanism 21 will spray liquid only when the holding block moves away from the circular saw blade 11 (i.e., in the process of cleaning the debris in the receiving groove 1241), thereby reducing the waste of liquid and saving the use cost.
