Description

Technical Field

[0001] The present invention relates to the technical field of metal material processing, in particular to a metal material shearing machine. Background Art

[0002] Metal shearing machine is a kind of mechanical equipment for cutting metal plates, bars, etc.

[0003] Existing devices of this type have the problem of inconvenient debris recovery. For example, the Chinese patent publication number "CN119216653A" discloses a raw material shearing device for the production of metal decorative panels. A shearing groove is provided in the device. When in use, metal debris falls to the bottom of the shearing groove by gravity. However, when actually cutting metal coils, the length of the coil is too long, which causes the cutting time of the circular saw blade to be extended accordingly, which makes the temperature of the circular saw blade higher. Therefore, when cutting metal coils, it is necessary to spray cutting fluid on the tool. In this device, the chips fall into the shearing groove by gravity, and the sprayed cutting fluid also falls with them. This causes the cutting fluid to mix with the metal chips, making it inconvenient to recover the chips. Based on this, the present application proposes a metal material shearing machine. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a metal material shearing machine.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A metal material shearing machine comprises a cutting mechanism, a reflux mechanism, and a separation mechanism, wherein the cutting mechanism is used to cut metal coils, the reflux mechanism is used to reflux chips and cutting fluid, and the separation mechanism is used to separate the cutting fluid and chips; The cutting mechanism is provided with a main shaft, a main shaft motor and a second belt transmission group, wherein the second belt transmission group transmits the power of the main shaft motor to the main shaft, the main shaft is provided with a circular saw blade, and the cutting mechanism is driven by the main shaft motor; When the cutting mechanism is driven, the output shaft of the spindle motor rotates, and the power is transmitted to the spindle through the second belt drive group, and the circular saw blade rotates to cut the metal coil; The reflux mechanism is provided with a number one and a half gear, a number one rack, a baffle, a push rod, and a return spring. The reflux mechanism is driven by the main shaft. When the reflux mechanism is driven, the number one and a half gears rotate to move the number one rack in a straight line. The return spring can reset the number one rack, thus forming a reciprocating motion to transport the metal chips to the separation mechanism. The separation mechanism is provided with a separation motor, a No. 2 gear transmission group, an outer separation barrel, and an inner separation barrel. The separation mechanism is driven by the separation motor. When the separation motor drives the separation mechanism, the main shaft rotates, and the power is transmitted to the inner separation barrel through the No. 2 gear transmission group, so that the inner separation barrel rotates and generates centrifugal force to separate the coolant remaining in the metal chips from the metal debris.

[0006] Preferably, support frames are provided on both sides of the cutting mechanism, and a chip box and a liquid storage tank are provided on the side walls of one of the support frames. The residual cutting fluid separated by the separation mechanism flows back to the liquid storage tank, and the metal debris separated by the separation mechanism flows into the chip box.

[0007] Preferably, a placement plate, an active roller, and a No. 1 passive roller group and a No. 2 passive roller group are provided between the support frames, and the active roller is located below the No. 1 passive roller group.

[0008] Preferably, the first passive roller set and the second passive roller set are both provided with passive rollers, and the active rollers actively rotate to allow the metal coil to pass between the first passive roller set and the active rollers.

[0009] Preferably, the circular saw blades are equidistantly distributed, a belt transmission group is provided on the side of the active roller, and a conveying motor is provided below the active roller, and the conveying motor is used to drive the active roller.

[0010] Preferably, a cylinder and a guide rod are further provided inside the first passive roller group, and the cylinder is used to move the multiple passive rollers and provide pressure on the metal coil.

[0011] Preferably, the outer separation barrel and the inner separation barrel are both tilted, and the tilt angles of the outer separation barrel and the inner separation barrel are the same.

[0012] Preferably, one end of the outer separation barrel and the inner separation barrel close to the separation motor is higher than one end of the liquid storage tank.

[0013] The present invention has the following beneficial effects: 1. By setting up a separation mechanism, the device can separate the chips generated by cutting from the cutting fluid, which allows the device to avoid the problem of inconvenient chip recovery caused by the mixing of cutting fluid and metal chips. When the separation mechanism is working, the separation motor works to rotate the inner separation barrel to generate centrifugal force, thereby separating the cutting fluid remaining in the metal chips from the metal chips themselves, thus avoiding the problem of inconvenient chip recovery caused by the mixing of cutting fluid and metal chips.

[0014] 2. By setting up a reflux mechanism, the metal chips and residual cutting fluid in this device can be diverted to different places. When the reflux mechanism is working, the residual cutting fluid and metal debris are separated by centrifugal force. The metal debris then slides through the inner separation barrel onto the guide plate and then falls into the debris box along the inclined plane on the guide plate. The cutting fluid then flows back to the liquid storage tank.

[0015] 3. By setting the buffer plate, impact plate and No. 1 buffer spring, when the device is working, the impact plate can knock on the bottom of the baffle, so that the metal debris attached to the bottom of the baffle is knocked down by vibration, thereby avoiding the accumulation of metal chips at the bottom of the baffle.

DETAILED DESCRIPTION

[0018] The technical solutions 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 only part of the embodiments of the present invention, rather than all the embodiments. Example 1:

[0019] A metal material shearing machine includes a cutting mechanism, a reflux mechanism, and a separation mechanism. The cutting mechanism is used to cut metal coils, the reflux mechanism is used to reflux chips and cutting fluid, and the separation mechanism is used to separate cutting fluid and chips. The cutting mechanism is provided with a spindle 11, a spindle motor 34, and a second belt drive group 20. The second belt drive group 20 transmits the power of the spindle motor 34 to the spindle 11. The spindle 11 is provided with circular saw blades 6, which are equidistantly distributed. The cutting mechanism is driven by the spindle motor 34.

[0020] When the cutting mechanism is driven, the output shaft of the spindle motor 34 rotates, and the power is transmitted to the spindle 11 through the second belt transmission group 20, and the circular saw blade 6 rotates, so that the metal coil is cut.

[0021] Support frames 2 are provided on both sides of the cutting mechanism, and a placement plate 10, an active roller 12, and a No. 1 passive roller group 1 and a No. 2 passive roller group 3 are provided between the support frames 2. The active roller 12 is located below the No. 1 passive roller group 1. A chip box 9 and a liquid storage tank 5 are provided on the side wall of one of the support frames 2. The residual cutting fluid separated by the separation mechanism flows back to the liquid storage tank, and the metal debris separated by the separation mechanism flows into the chip box.

[0022] Both the No. 1 passive roller group 1 and the No. 2 passive roller group 3 are provided with a passive roller 7. The interior of the No. 1 passive roller group 1 is also provided with a cylinder 13 and a guide rod 14. The cylinder 13 is used to move the multiple passive rollers 7 and provide pressure on the metal coil. The active roller 12 actively rotates to allow the metal coil to pass between the No. 1 passive roller group 1 and the active roller 12. A No. 1 belt drive group 19 is provided on the side of the active roller 12, and a conveying motor 15 is provided below the active roller 12. The conveying motor 15 is used to drive the active roller 12.

[0023] In this embodiment, the cutting mechanism can be specifically composed of the following components: a number one passive roller group 1, a passive roller 7, a main shaft 11, a circular saw blade 6, an active roller 12, a conveying motor 15, a number one belt drive group 19, a cylinder 13, a guide rod 14, and a main shaft motor 34.

[0024] The interior of the No. 1 passive roller group 1 is divided into two parts, one of which is the outer shell of the No. 1 passive roller group 1, and the other part is rotatably connected to multiple passive rollers 7, and this part is fixedly connected to the output rod of the cylinder 13, and the cylinder 13 is fixedly connected to the inner top of the No. 1 passive roller group 1, as shown in FIG. Figure 4 shown.

[0025] The main shaft 11 is fixedly connected to one of the pulleys in the No. 2 belt drive group 20, the main shaft motor 34 is fixedly connected to the side wall of the support frame 2, and its output shaft is fixedly connected to the other pulley in the No. 2 belt drive group 20. Power is transmitted between the two pulleys through the transmission belt. The main shaft 11 is fixedly connected to the circular saw blade 6, and the end of the main shaft 11 away from the main shaft motor 34 is fixedly connected to the No. 1 half gear 16.

[0026] When the device is working, the metal coil is first cut into an initial groove by the circular saw blade 6, and then one end of the cut groove is placed under the first passive roller group 1. Then the pneumatic cylinder 13 is activated, and the cylinder 13 presses down the multiple passive rollers 7 to provide a certain pressure on the metal coil. Then the conveying motor 15 and the spindle motor 34 are started. The conveying motor 15 allows the metal coil to be conveyed out from the first passive roller group 1. During the process, it will be cut by the circular saw blade 6. The multiple circular saw blades 6 will cut the metal coil into long strips of equal parts, such as Figure 1 As shown in .

[0027] The conveying motor 15 transmits power through the No. 1 belt drive group 19. When the conveying motor 15 rotates, the power is transmitted to the active roller 12 through the conveying motor 15. The active roller 12 rotates to convey the metal coil. The cylinder 13 presses the multiple passive rollers 7 on the metal coil, allowing it to pass more smoothly between the multiple passive rollers 7 and the active roller 12.

[0028] The circular saw blade 6 is driven by the No. 2 belt drive group 20. When working, the spindle motor 34 transmits power to the No. 2 belt drive group 20, and then the No. 2 belt drive group 20 transmits power to the spindle. Since the circular saw blade 6 is fixedly connected to the spindle 11, the spindle 11 rotates, and the circular saw blade 6 also rotates and cuts the metal coil. It should be noted that the direction of rotation of the circular saw blade 6 during cutting is opposite to the direction of movement of the metal coil. That is, the circular saw blade 6 rotates forward to cut the metal coil, and the metal coil moves backward. The conveying direction of the metal coil is from the direction of the No. 2 passive roller group 3 to the direction of the No. 1 passive roller group 1, and the cutting direction is from the direction of the No. 1 passive roller group 1 to the direction of the No. 2 passive roller group 3. Example 2:

[0029] The separation mechanism is provided with a separation motor 23, a second gear transmission group 25, an outer separation barrel 39, and an inner separation barrel 35. The separation mechanism is driven by the separation motor 23. When the separation motor 23 drives the separation mechanism, when the main shaft rotates, the power is transmitted to the inner separation barrel 35 through the second gear transmission group 25.

[0030] In order to make the inner separation barrel 35 rotate and generate centrifugal force, the outer separation barrel 39 and the inner separation barrel 35 are both tilted, and the outer separation barrel 39 and the inner separation barrel 35 have the same tilt angle, so that the coolant remaining in the metal chips is separated from the metal debris, and the end of the outer separation barrel 39 and the inner separation barrel 35 close to the separation motor 23 is higher than the end of the liquid storage tank 5.

[0031] In this embodiment, the separation mechanism can be specifically composed of the following structures: No. 1 and a half gear 16, push plate 21, No. 1 rack 17, push plate 21, slide rod 22, return spring 33, baffle 38, separation motor 23, inner separation barrel 35, outer separation barrel 39, feed port 24, No. 2 gear transmission group 25.

[0032] Among them, the No. 1 and a half gear 16 is fixedly connected to the main shaft 11, the push plate 21 is fixedly connected to the slide rod 22, and one end of the return spring 33 is fixedly connected to the slide rod 22 behind the push plate 21. The other end of the return spring 33 is fixedly connected to the inner wall of the baffle 38, and the return spring 33 is located on the slide rod 22.

[0033] The No. 1 rack 17 can engage with the No. 1 half gear 16, the push plate 21 is fixedly connected to the No. 1 rack 17, the slide rod 22 is slidably connected to the baffle 38, the separation motor is fixedly connected to the side wall of the baffle 38, and the power is transmitted between the separation motor 23 and the inner separation barrel 35 through the No. 2 gear transmission group 25. The output shaft of the separation motor 23 is fixedly connected to one of the gears in the No. 2 gear transmission group 25, and the other gear is fixedly connected to the inner separation barrel 35. The feed port 24 is rotationally sealed and connected to the inner separation barrel 35, and the feed port 24 is fixedly connected to the baffle 38.

[0034] The outer separation barrel 39 is rotatably connected to the inner separation barrel 35 . There is a certain distance between the outer separation barrel 39 and the inner separation barrel 35 . The outer separation barrel 39 is connected to the liquid storage tank 5 . The outlet of the inner separation barrel 35 is located above the guide plate 8 .

[0035] Since the rotation of the main shaft 11 will drive the No. 1 and a half gears 16 to rotate, the No. 1 and a half gears 16 are meshed with the No. 1 and No. 1 racks 17, and the No. 1 and No. 1 racks 17 are fixedly connected to the push plate 21, the rotation of the No. 1 and a half gears 16 will cause the No. 1 and No. 1 racks 17 to move. When the No. 1 and a half gears 16 rotate, the No. 1 and No. 1 racks 17 will move toward the direction of the slide bar 22. Since the meshing between the No. 1 and No. 1 racks 17 and the No. 1 and a half gears 16 is intermittent, the push rod 32 will be pushed to reset by the return spring 33 under the action of the return spring 33, so the push rod 32 will reciprocate under the action of the No. 1 and a half gears 16.

[0036] When the circular saw blade 6 cuts the metal coil, it will spray cutting fluid to facilitate the cutting of the metal coil. The debris will fall between the baffles 38 due to the cutting direction of the circular saw blade 6. The cutting fluid will also fall between the baffles 38 due to gravity. At this time, the No. 1 and a half gears 16 will rotate and make the No. 1 and No. 1 racks 17 move linearly. Because its engagement with the No. 1 and No. 1 racks 17 is intermittent, when the No. 1 and No. 1 racks 17 are pushed by the No. 1 and a half gears 16 toward the direction of the slide bar 22, the return spring 33 will be stressed. When the No. 1 and a half gears 16 are not engaged with the No. 1 and No. 1 racks 17, it will reset under the action of the return spring 33, thereby forming a reciprocating motion, pushing the metal debris into the hollow groove in the inner wall of the baffle 38, causing it to fall into the V-shaped part of the baffle 38 for reference. Figure 9 , and falls to the inner bottom of the baffle 38 under the action of gravity.

[0037] The inner bottom of the baffle 38 is an inclined plane. The end close to the second half gear 31 is higher and the end close to the feed port 24 is lower. Therefore, when the metal chips and cutting fluid fall into the bottom of the baffle 38, they will flow into the inner separation barrel 35 because of the inclined surface of the bottom of the baffle 38. Then, the separation motor 23 is started, and the separation motor 23 drives the inner separation barrel 35 to rotate. The structure of the inner separation barrel 35 is shown in FIG. Figure 12 There are multiple holes on it for throwing out the cutting fluid. When the inner separation barrel 35 rotates, the metal chips are subjected to centrifugal force due to the rotation, so the residual cutting fluid on the metal chips will be thrown out under the action of centrifugal force, thereby separating the residual metal chips from the residual cutting fluid, making the metal chips easier to be recycled.

[0038] There is a certain gap between the outer separation barrel 39 and the inner separation barrel 35. Therefore, when the metal chips are located in the inner separation barrel 35 to separate the residual cutting fluid, the cutting fluid will be located between the outer separation barrel 39 and the inner separation barrel 35, and flow into the liquid storage tank 5 along the inclined slope of the inner separation barrel 35 and the outer separation barrel 39. The metal chips flow out to one end of the No. 2 half gear 31, and finally flow out to the guide plate 8 under the action of gravity. There is an inclined plane on the guide plate 8, and the bottom end of the inclined slope is fixedly connected to the debris box 9. The debris box 9 has an opening at the upper end, which is hollow. When the metal chips fall on the inclined plane, the metal chips will fall into the debris box 9 under the action of gravity. Example 3:

[0039] The reflux mechanism is provided with a No. 1 and a half gear 16, a No. 1 rack 17, a baffle 38, a push rod 32, and a return spring 33. The reflux mechanism is driven by the main shaft 11. When the reflux mechanism is driven, the No. 1 and a half gear 16 rotates to make the No. 1 rack 17 move linearly. The return spring 33 can reset the No. 1 rack 17, thus forming a reciprocating motion to allow the metal chips to be transported to the separation mechanism.

[0040] In this embodiment, the reflux mechanism can be composed of the following components: a liquid storage tank 5, a spring rod 26, a second rack 27, a buffer plate 28, an impact plate 29, a first buffer spring 30, a collision block 36, a second buffer spring 37, and a second half gear 31.

[0041] Among them, the liquid storage tank 5 is placed at the bottom of the support frame 2, the liquid storage tank 5 is communicated with the outer separation barrel 39, the spring rod 26 is fixedly connected to the outer wall of the baffle 38, the impact plate 29 is located at the bottom of the baffle 38 and is slidingly connected to the baffle 38, the No. 1 buffer spring 30 is located below the impact plate 29 and is fixedly connected to the buffer plate 28, the buffer plate 28 and the impact plate 29 are slidingly connected, the No. 2 half gear 31 is engaged with the No. 2 rack 27, and the No. 2 rack 27 is slidingly connected to the spring rod 26.

[0042] A spring for resetting is provided in the spring rod 26 , and the spring is located below the sliding connection between the second rack 27 and the spring rod 26 , and the second half gear 31 is fixedly connected to the inner separation barrel 35 .

[0043] refer to Figure 7-9When the inner separation barrel 35 rotates, it also drives the second half gear 31 to rotate. This rotation also drives the second rack 27 to move. The second rack 27 is slidably connected to the inside of the spring rod 26. A spring is also located inside the spring rod 26 to provide a reset. Therefore, when the second half gear 31 rotates, it causes the second rack 27 to move. The spring inside the spring rod 26 then pushes the second rack 27 upward, creating a reciprocating motion. It should be noted that the second rack 27 is hollow, and the impact plate 29 is hollow. Therefore, both the second rack 27 and the impact plate 29 are relatively lightweight.

[0044] When the No. 2 rack 27 moves back and forth, it will drive the impact plate 29 to move back and forth. Under the action of the reciprocating movement, the impact plate 29 will hit the impact block 36, and the impact block 36 will transmit the impact force to the bottom of the baffle 38, thereby preventing metal chips from sticking to the bottom of the baffle 38.

[0045] When the impact plate 29 hits the impact block 36, since a buffer spring 30 is arranged underneath it, the impact force provided by the inner separation barrel 35 does not directly act on the impact block 36, but is weakened due to the change in the position of the impact plate 29, so it will not damage the internal components of the device.

[0046] It should be noted that if Figure 9 as well as Figure 7 As shown, the structures of the belt drive group and the gear drive group in this device are the same. The structure of the belt drive group is a pair of pulleys matched with the transmission belt, and its working principle is the same as that of the belt drive. The gear drive group is a pair of mutually meshing spur gears, and its working principle is the same as that of the gear drive.

[0047] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
