[0024] The beneficial effects of the present invention are:

[0025] 1. The first servo motor drives the feeding roller body to rotate. When one side of the empty slot rotates to the junction of the feeding hole and the unloading plate, a group of metal round bars will fall into the empty slot, and then be brought to one side of the connecting table through the rotation of the feeding roller body, and finally fall into the gap between the two groups of material transport pipes through the connecting table; at the same time, the telescopic rod can be pulled out according to the diameter of the metal round bars to ensure the distance from the round bar limiting plate to the inner wall of the other side of the empty slot. Only one group of metal round bars will fall into the empty slot each time, thereby improving the accuracy of unloading, avoiding manual loading, and reducing labor intensity.

[0026] 2. When a batch of metal round bars slide down the unloading plate, the filter plate is driven down by the first electric push rod until the distance between the filter plate and the unloading plate is only enough for one group of metal round bars to pass through, thereby improving the neatness of the metal round bars when they slide down, preventing multiple groups of metal round bars from accumulating at the junction of the feeding hole and the unloading plate, and causing material jamming, thereby improving the smoothness of the unloading work.

[0027] 3. First, the metal round bar is rotated by the rotating roller, and at the same time, the cutting saw disc is driven to slowly descend by the third electric push rod, so that during the sawing work, the cutting saw disc can cut the metal round bar from different angles and from shallow to deep, so that the force points between the cutting saw disc and the metal round bar are more evenly distributed, reducing the sawing resistance, shortening the sawing time, and thereby improving work efficiency.

[0028] 4. By moving the first slider, the pushing column can push the metal round bar material between the two sets of material transport pipes toward the cutting saw disk. Regardless of the diameter and length of the metal round bar material, the pushing work can be achieved by adjusting the position of the pushing column, thereby improving compatibility. At the same time, during the pushing process, the metal round bar material will be limited from both sides by the two sets of material transport pipes, thereby improving the stability and smoothness of the pushing of the metal round bar material.

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The embodiment of the present invention provides a metal round bar sawing device, the sawing device comprising a material storage component 1, a material transport component 2, a push tube component 3, a rotating component 4 and a sawing component 6.

[0046] The end of the material transport component 2 close to the rotating component 4 is connected to the first housing 5, and the sawing component 6 is installed in the first housing 5, and the cutting part of the sawing component 6 is located above the connection between the material transport component 2 and the rotating component 4. The sawing component 6 is used to saw the metal round bar material.

[0047] The sawing device further includes a discharge plate 8, and a discharge port 7 is provided on a side wall of the first shell 5 away from the material transport component 2. The discharge plate 8 is fixedly mounted on the discharge port 7, one end of the discharge plate 8 is located directly below the cutting portion of the sawing component 6, and the other end passes through the outside of the first shell 5. A filter screen is provided on the discharge plate 8. After sawing, the cut metal round bar material will fall onto the discharge plate 8 and slide out of the first shell 5 through the discharge plate 8; and in the process of sliding, the debris generated by sawing on the metal round bar material will fall below the discharge plate 8 through the filter screen.

[0048] The material transport assembly 2 includes a first material transport pipe mounting plate 201, a second material transport pipe mounting plate 203, two groups of material transport pipes 204 and a plurality of groups of hollow pipes 205. Figure 3 and Figure 4As shown, a group of material transport pipe baffles 202 are fixedly installed on both sides of the first material transport pipe mounting plate 201, and the other ends of the two groups of material transport pipe baffles 202 are fixedly installed on the second material transport pipe mounting plate 203. The two ends of the two groups of material transport pipes 204 are fixedly installed on the first material transport pipe mounting plate 201 and the second material transport pipe mounting plate 203, respectively, and the two groups of material transport pipes 204 are symmetrically arranged on both sides of the central axis of the first material transport pipe mounting plate 201. Several groups of hollow tubes 205 are evenly sleeved on the two groups of material transport pipes 204, and the hollow tubes 205 can rotate freely along the round points of the material transport pipes 204. The highest point of the second material transport pipe mounting plate 203 is lower than the highest point of the hollow tubes 205.

[0049] When transporting the material, the metal round bar material will fit on the hollow tubes 205 on both sides. During the transportation of the metal round bar material, the metal round bar material is pushed to one side of the sawing assembly 6 by the protruding portion of the pushing tube assembly 3, and the sawing assembly 6 is used to perform sawing work. During the pushing process, the metal round bar material will be limited from both sides by the two sets of transporting tubes 204, thereby improving the stability and smoothness of pushing the metal round bar material.

[0050] The push tube assembly 3 includes a second housing 301, a second servo motor 302, a screw rod 303 and a push tube column 305. Figure 3 and Figure 5 As shown, the second housing 301 is located at the bottom of the two groups of the material transporting pipes 204, and the second servo motor 302 is fixedly installed on a side wall of the second housing 301.

One end of the first slider 304 is threadedly connected to the screw rod 303, and the other end is fixedly installed at the bottom of the push pipe column 305. The push pipe column 305 is located between the two groups of the material transporting pipes 204, and the highest point of the push pipe column 305 is higher than the highest point of the hollow pipe 205.

[0051] When the metal round bar needs to be pushed, the second servo motor 302 is first started, and the screw rod 303 is driven to rotate by the second servo motor 302, and then the first slider 304 and the push pipe column 305 are driven to move by the rotation of the screw rod 303, so that the metal round bar is pushed from the position between the two groups of material transport pipes 204 by the push pipe column 305. Regardless of the diameter and length of the metal round bar, the pushing work can be achieved by adjusting the position of the push pipe column 305, thereby improving compatibility.

[0052] The material storage assembly 1 includes a loading roller support frame 101, a material discharge plate 103, a first servo motor 104, a first rotating rod 110 and two sets of material blocking plates 102. Figure 6 and Figure 7 , the feeding roller support frame 101 is located on one side of one group of the material transport pipe baffles 202, and a feeding hole 111 is opened in the feeding roller support frame 101. The first servo motor 104 is fixedly mounted on the inner wall of one side of the feeding hole 111, and the output end of the first servo motor 104 is transmission-connected to one end of the first rotating rod 110 through a coupling; the other end of the first rotating rod 110 is rotationally connected to the inner wall of the feeding hole 111 away from the first servo motor 104 through a bearing seat. The first rotating rod 110 is equipped with a feeding roller mechanism 107. One end of the unloading plate 103 is attached to the bottom of the inner wall of the feeding hole 111 away from the material transport component 2. Two groups of the baffle plates 102 are symmetrically mounted on both sides of the central axis of the side wall of the feeding roller support frame 101 close to the unloading plate 103, and the other ends of the two groups of the baffle plates 102 are both mounted on the unloading plate 103. The blanking plate 103 is configured as an inclined structure, and one end of the blanking plate 103 close to the loading hole 111 is lower than the other end.

[0053] The material storage assembly 1 further includes a filter plate mounting plate 109, a first electric push rod 105, a filter plate 106 and a connecting platform 108. The filter plate mounting plate 109 is fixedly mounted on the top of the two groups of the material blocking plates 102, the first electric push rod 105 is fixedly mounted on the lower surface of the filter plate mounting plate 109, and the filter plate 106 is fixedly mounted on the output end of the first electric push rod 105. The filter plate 106 is tilted, and the tilt angle of the filter plate 106 is the same as the tilt angle of the unloading plate 103. One end of the connecting platform 108 is fixedly mounted on the bottom of the inner wall of the side of the loading hole 111 away from the unloading plate 103, and the other end is located directly above the gap between the two groups of the material transport pipes 204.

[0054] The feeding roller mechanism 107 includes a feeding round roller 1071, a fan-shaped telescopic rod 1074, a fixing bolt 1076 and a round rod limiting plate 1077. Figure 8As shown, the feeding roller 1071 is sleeved on the first rotating rod 110, and a fan-shaped slot 1072 is provided on the outer wall of the feeding roller 1071. A fan-shaped ring-shaped limiting hole 1073 is provided on the inner wall of one side of the fan-shaped slot 1072, and one end of the fan-shaped ring-shaped telescopic rod 1074 can be movably inserted into the fan-shaped ring-shaped limiting hole 1073. A plurality of groups of threaded holes 1075 are evenly spaced on a side wall of the fan-shaped telescopic rod 1074 away from the center point of the feeding roller 1071, and one end of the fixing bolt 1076 can be movably inserted into the fan-shaped limiting hole 1073 and threadedly connected in any group of the threaded holes 1075. The round rod limiting plate 1077 is located in the fan-shaped slot 1072, and the round rod limiting plate 1077 is fixedly installed on the other end of the fan-shaped telescopic rod 1074.

[0055] First, place all the round metal bars to be sawed on the blanking plate 103. Due to gravity, the round metal bars will all slide to the junction of the upper feeding hole 111 and the blanking plate 103. Then, according to the diameter of the round metal bars, determine the length of the fan-shaped telescopic rod 1074 to be pulled out, and screw the fixing bolts 1076 into the corresponding set of threaded holes 1075. Ensure that the distance from the round bar limit plate 1077 to the inner wall on the other side of the fan-shaped slot 1072 is exactly the same as the outer diameter of the round metal bars. Then start the first servo motor 104, and drive the first rotating rod 110 and the feeding roller 1071 to rotate through the first servo motor 104. When one side of the fan-shaped slot 1072 rotates to the junction of the feeding hole 111 and the unloading plate 103, a group of metal round bars will fall into the fan-shaped slot 1072, and under the action of the rotation of the feeding roller 1071, this group of metal round bars will be brought to the side of the connecting platform 108, and finally fall on the connecting platform 108 under the action of gravity. Then, through the connecting platform 108, it falls into the gap between the two groups of material transport pipes 204. Without manual feeding, the number of metal round bars of different diameters can be accurately quantified, which not only reduces the labor intensity, but also improves the accuracy of automatic feeding.

[0056] While batches of metal round bars are sliding up and down on the unloading plate 103, the filter plate 106 is driven down by the first electric push rod 105 until the distance between the filter plate 106 and the unloading plate 103 is only enough for one group of metal round bars to pass through, thereby improving the neatness of the metal round bars as they slide down, preventing multiple groups of metal round bars from piling up at the junction of the loading hole 111 and the unloading plate 103 and causing material jamming, thereby improving the smoothness of the unloading work.

[0057] The rotating assembly 4 includes a dust cover 401, a second electric push rod 402, a first transfer roller mounting plate 403, a third servo motor 405, a second rotating rod 406, a transfer roller 407 and two sets of second transfer roller mounting plates 404. Fig. 9 As shown, the bottoms of both sides of the dust cover 401 are symmetrically mounted on the top of one side of the two groups of the material conveying pipe baffles 202 close to the first housing 5. The second electric push rod 402 is fixedly mounted on the top inner wall of the dust cover 401, the first material transfer roller mounting plate 403 is fixedly mounted on the output end of the second electric push rod 402, and two groups of the second material transfer roller mounting plates 404 are symmetrically mounted on both sides of the lower surface of the first material transfer roller mounting plate 403.

The material transfer roller 407 is sleeved on the second rotating rod 406, and the central axis of the material transfer roller 407 is on the same vertical plane as the central axis of the first material conveying pipe mounting plate 201.

[0058] After the metal round bar is pushed to the bottom of the cutting part of the sawing assembly 6, the second electric push rod 402 is first started, and the material transfer roller 407 is driven to descend by the second electric push rod 402 until the material transfer roller 407 can be attached to the metal round bar from the top. Then the third servo motor 405 is started, and the second rotating rod 406 and the material transfer roller 407 are driven to rotate by the third servo motor 405, and the metal round bar is also driven to rotate by the rotation of the material transfer roller 407. When the metal round bar is sawed, the cutting part of the sawing assembly 6 can contact the metal round bar in turn according to the direction of its rotation, so that the force points are distributed more evenly, the sawing resistance is reduced, the sawing time is shortened, and the work efficiency is improved.

[0059] The sawing assembly 6 includes a third electric push rod 601, a first saw disc mounting plate 602, a fourth servo motor 604, a transmission mechanism, a third rotating rod 607, a cutting saw disc 608 and two sets of second saw disc mounting plates 603.

The cutting saw disc 608 is fixedly sleeved on the third rotating rod 607. The fourth servo motor 604 is mounted on one group of the second saw disc mounting plates 603, and the output end of the fourth servo motor 604 is transmission-connected to the third rotating rod 607 through a transmission mechanism.

[0060] The transmission mechanism includes a belt 606 and two groups of pulleys 605. The two groups of pulleys 605 are respectively mounted on the output end of the fourth servo motor 604 and the third rotating rod 607. The two groups of pulleys 605 are connected by the belt 606.

[0061] First, the third electric push rod 601 drives the cutting saw disc 608 to descend and fit it with the metal round bar material, then the fourth servo motor 604 is started, and the transmission connection relationship between the two sets of pulleys 605 is utilized, so that the operation of the fourth servo motor 604 drives the third rotating rod 607 and the cutting saw disc 608 to rotate, thereby realizing the sawing function of the cutting saw disc 608 on the metal round bar material. During the sawing process, the third electric push rod 601 drives the cutting saw disc 608 to continue to slowly descend, and under the condition that the metal round bar material rotates itself, the cutting saw disc 608 cuts the metal round bar material from different angles and from shallow to deep. This further improves the sawing efficiency.

[0062] The loading roller 1071 is driven to rotate by the first servo motor 104. When one side of the fan-shaped slot 1072 rotates to the junction of the loading hole 111 and the unloading plate 103, a group of metal round bars will fall into the fan-shaped slot 1072, and then be brought to the side of the connecting platform 108 through the rotation of the loading roller 1071, and finally fall into the gap between the two groups of material transport pipes 204 through the connecting platform 108; at the same time, the fan-shaped telescopic rod 1074 can be pulled and pulled according to the diameter of the metal round bars to ensure the distance from the round bar limiting plate 1077 to the inner wall of the other side of the fan-shaped slot 1072. Only one group of metal round bars will fall into the fan-shaped slot 1072 each time, thereby improving the accuracy of unloading, avoiding manual loading, and reducing labor intensity. While a batch of metal round bars are sliding up and down on the unloading plate 103, the filter plate 106 is driven down by the first electric push rod 105 until the distance between the filter plate 106 and the unloading plate 103 is only enough to pass one group of metal round bars, thereby improving the neatness of the metal round bars when they are sliding down, preventing multiple groups of metal round bars from accumulating at the junction of the loading hole 111 and the unloading plate 103, and causing the material jam, thereby improving the smoothness of the unloading work. The metal round bars are first driven to rotate by the material transfer roller 407, and at the same time, the cutting saw disc 608 is driven to slowly descend by the third electric push rod 601, so that when it is sawing, the cutting saw disc 608 can cut the metal round bars from different angles and from shallow to deep, so that the distribution of the force points between the cutting saw disc 608 and the metal round bars is more uniform, reducing the sawing resistance, shortening the sawing time, and thereby improving the work efficiency. The second servo motor 302 drives the lead screw 303 to rotate, and the rotation of the lead screw 303 drives the first slider 304 to move, so that the pushing tube column 305 can push the metal round bar material between the two groups of material transport tubes 204 to move in the direction of the cutting saw disk 608. Regardless of the diameter and length of the metal round bar material, the pushing work can be achieved by adjusting the position of the pushing tube column 305, thereby improving compatibility; at the same time, during the pushing process, the metal round bar material will be limited from both sides by the two groups of material transport tubes 204, thereby improving the stability and smoothness of the pushing of the metal round bar material.
