Description

Technical Field

[0001] The utility model specifically relates to a round steel cutting machine. Background Art

[0002] The round steel cutting machine is a high-power and high-load machine tool, mainly used for cutting forging blanks in forging plants. It can also be used for large-scale bar blanking and steel bar cutting. With the continuous improvement of users, the round steel cutting machine is equipped with a fixed needle mechanism, which also enables the round steel cutting machine to have good precision when cutting blanks. For example, the "Round Steel Cutting Machine" disclosed in patent CN200420084148.X adopts a high-power motor as the power. After three-stage deceleration, it drives the shearing mechanism, which can generate huge shearing force. Its accuracy can be controlled within 1~2mm, thereby reducing material waste and greatly improving production efficiency and the accuracy of shearing workpieces.

[0003] However, the round steel cutting machine is not only a high-power and high-load machine tool, but also a machine tool with a huge appearance. Therefore, the tool used to cut the workpiece is very heavy, and the tool is an accessory that needs to be replaced frequently by users. However, the traditional round steel cutting machine requires the tool to be replaced from the side of the round steel cutting machine, which is very demanding on the physical fitness of technicians and has great difficulty in replacement and installation. When the user uses the round steel cutting machine to cut the workpiece, the workpiece connection surface continues to decrease, causing the workpiece to shake, resulting in errors in the workpiece cutting and the cut surface of the workpiece is not smooth enough. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a round steel cutting machine in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a round steel cutting machine, comprising a base, a driving source and a main mounting frame are provided on the base, a reduction transmission mechanism is provided on the main mounting frame, a driving wheel is provided on the output end of the driving source, prompting the driving source and the reduction transmission mechanism to be linked, a pin mechanism is provided on the upper end of the main mounting frame, a linkage component is provided on the reduction transmission mechanism, one end of the linkage component is rotatably connected to the reduction transmission mechanism, and a shearing mechanism is provided on the other end, a tool mounting opening is provided on the upper end face of the main mounting frame, the shearing mechanism comprises a shearing piece mounting seat and a shearing piece, one end of the shearing piece mounting seat is connected to the linkage component, and the other end is provided with a shearing piece mounting groove, prompting the shearing piece to be fixedly installed on the shearing piece mounting seat; a stabilizing component is provided on the main mounting frame, the stabilizing component comprises an adjustable driving source, and a stabilizing clamp component is provided on the output end of the adjustable driving source.

[0006] The above technical solution is adopted, and the round steel cutting machine is a large-volume equipment with a very heavy weight. In the process of continuously cutting the workpiece, the shearing parts used for cutting in the round steel cutting machine will be constantly worn, which requires users to frequently check and replace them. The traditional way of replacing the shearing parts is for the technician to dismantle the damaged shearing parts and then pick up the new shearing parts, which requires the technician to have high physical fitness and stably replace the shearing parts from the side of the round steel cutting machine, which is very difficult to install. A tool mounting opening is provided on the main mounting frame, and a shearing part mounting slot is provided on the shearing part mounting seat. The technician only needs to put the shearing part into the tool mounting opening, and the shearing part will naturally fall into the shearing part mounting slot. At this time, the technician only needs to slightly adjust the shearing part, and then the technician locks the shearing part on the shearing part mounting seat to complete the installation. This setting greatly reduces the installation difficulty of the technician in replacing the shearing parts, improves work efficiency, and improves the user experience.

[0007] The driving source is a high-power and high-load motor. When the technician controls the round steel cutting machine to cut the workpiece, the driving source drives the active wheel to rotate, the active wheel drives the reduction transmission mechanism to rotate, the reduction transmission mechanism drives the linkage component to move repeatedly, and finally the linkage component drives the shearing mechanism to move repeatedly to perform the cutting work. The cutting force is converted from the rotational force generated by the driving source. A certain thrust will also be generated during cutting, which will cause the workpiece to be unstable. By setting a stable component, when the round steel cutting machine cuts the workpiece, the adjustable driving source will control the stable clamp component to move until it contacts the workpiece and acts in the opposite direction to the cutting force exerted by the shearing piece on the workpiece. Through this design method, the stability of the workpiece is guaranteed when cutting. While the ejector mechanism reduces the cutting size error, the cutting error is further reduced, thereby improving the user experience.

[0008] The above-mentioned round steel cutting machine can be further configured as follows: the thimble mechanism includes a thimble mounting plate, a thimble drive mounting bracket is provided on the upper end surface of the thimble mounting plate, a supporting rib is provided on the upper end surface of the thimble mounting plate, a thimble drive mounting bracket is provided on the thimble drive source, and a first driving wheel is provided on the output end of the thimble drive source, a first screw rod mounting seat and a second screw rod mounting seat are provided at an interval of the lower end of the thimble mounting plate, a screw rod is provided between the first screw rod mounting seat and the second screw rod mounting seat, and a second driving wheel is provided at one end of the screw rod close to the first driving wheel, so as to promote the linkage between the screw rod and the thimble drive source; a flange is provided on the screw rod, and the flange slides along the screw rod, and slide rail mounting seats are provided on both sides of the screw rod, and a slide rail is provided on the slide rail, and a slider is slidably provided on the slide rail, and a first connecting plate is provided at the lower end of the slider, and the first connecting plate is fixedly connected to the slider, and a thimble fixing seat is provided at the lower end of the first connecting plate, and a thimble main body is provided in the thimble fixing seat, and the thimble main body is plugged and installed in the thimble fixing seat, and the thimble main body is fixedly connected to the thimble fixing seat.

[0009] By adopting the above technical solution, when the round steel cutting machine cuts workpieces of different orders, the sizes of the workpieces to be cut are different, and the user needs to adjust the ejector mechanism to the required position to ensure the dimensional accuracy of the cut workpiece and reduce material waste. Each adjustment requires the user to adjust the ejector mechanism by hand, and the manual method will inevitably produce excessive errors. By setting an ejector drive source, the ejector drive source drives the first drive wheel to rotate, and the first drive wheel drives the second drive wheel to rotate through the synchronous belt, thereby driving the screw to rotate, and the screw control flange rotates, thereby driving the ejector body to move. The ejector drive source is a servo motor. By setting a matching electronic control system, the technician only needs to operate the control unit to control the sliding of the ejector mechanism. This setting reduces the dimensional error of the cut workpiece, improves work efficiency, improves the convenience of using the round steel cutting machine, and improves the user experience.

[0010] The above-mentioned round steel cutting machine can be further configured as: the reduction transmission mechanism includes a first transmission shaft, a second transmission shaft, and a third transmission shaft, the first transmission shaft, the second transmission shaft and the third rotating shaft are rotatably mounted on the main machine mounting frame, one end of the first transmission shaft is provided with a driven wheel, the other end of which is provided with a first-stage main gear, one end of the second transmission shaft is provided with a first-stage pinion, and the other end is provided with a second-stage main gear, the driven wheel is linked to the driving wheel, the first-stage main gear and the first-stage pinion are meshed and linked; one end of the third transmission shaft is provided with a second-stage pinion, and the other end is provided with a third-stage main gear, the third-stage main gear and the third-stage pinion are meshed and linked; a fourth transmission shaft is provided above the first transmission shaft and the second transmission shaft, the fourth transmission shaft is rotatably mounted on the main machine mounting frame, one end of the fourth transmission shaft is provided with a fourth-stage pinion, and the other end is provided with an eccentric shaft, a linkage assembly is fixedly installed on the eccentric shaft, so that the reduction transmission mechanism drives the shearing mechanism to move repeatedly.

[0011] By adopting the above technical solution, the workpiece cut by the round steel cutting machine has a certain hardness, and the required driving source needs to be a high-power and high-load motor. When using a high-power and high-load motor, the motor power is large and the motor speed will be too fast. By setting a reduction transmission mechanism, the initial speed of the driving wheel driven by the motor is set, and different transmission ratios are set through the reduction transmission mechanism to reduce the speed layer by layer, so that the round steel cutting machine will not produce invalid cutting work while ensuring the cutting force of the round steel cutting machine. In this way, the service life of the round steel cutting machine is improved, the noise generated during cutting work is reduced, and the user experience is improved.

[0012] The above-mentioned round steel cutting machine can be further configured as follows: the linkage assembly includes a connecting rod and a connecting rod mounting seat, the lower end of the connecting rod is detachably connected to the connecting rod mounting seat, the upper end of the connecting rod is connected to the shearing mechanism, and the connecting rod drives the shearing mechanism to reciprocate.

[0013] With the above technical solution, the round steel cutting machine is a device in which a driving source generates driving force to drive the reduction transmission mechanism to rotate, and the reduction transmission mechanism then drives the linkage assembly and the shearing mechanism to repeatedly perform cutting movements. As time goes by and the length of use continues to increase, the linkage assembly is inevitably worn. By setting the linkage assembly separately, when the connecting rod or the connecting rod mounting seat is worn or damaged, the linkage assembly can be easily removed by simply disassembling the connecting piece, thereby quickly replacing the linkage assembly, thereby reducing the maintenance and repair costs of the round steel cutting machine.

[0014] After using the round steel cutting machine to cut the workpiece, the technicians will inevitably need to check and maintain the various components and lubricate the components that need lubrication. The linkage assembly is set on the eccentric shaft and needs to rotate and rub continuously during operation. It is an important component that requires regular maintenance. When the user is about to perform lubrication, he only needs to slightly loosen the connecting piece connecting the connecting rod and the connecting rod mounting seat to create a tiny gap, and then pour the lubricating oil in to achieve the purpose of lubrication and maintenance, further reducing the maintenance cost of the round steel cutting machine.

[0015] The above-mentioned round steel cutting machine can be further configured as follows: the round steel cutting machine includes a feeding assembly, the feeding assembly includes a conveying member, a discharge opening is opened on the conveying member, roller mounting seats are fixedly installed on both sides of the conveying member, a roller is rotatably provided between the roller mounting seats, a discharge plate corresponding to the discharge opening is provided on the roller, the discharge plate is fixedly connected to the roller, a discharge plate control component is provided under the roller, the discharge plate control component is connected to the roller, and the discharge plate control component controls the rotation of the discharge plate and the rotating shaft.

[0016] By adopting the above technical solution, the round steel cutting machine is a fast cutting equipment. When the user uses the round steel cutting machine to process the workpiece, the processed workpiece will be quickly produced from the round steel cutting machine. By setting the feeding component, after the round steel cutting machine processes the workpiece, the processed workpiece will naturally and quickly fall into the feeding component. The technician only needs to set a material tray under the feeding component, and the processed workpiece will quickly fall into the material tray along the feeding component, so that the processed workpiece can be quickly collected. Through this setting, the convenience of users using the round steel cutting machine is improved, and the user experience is improved.

[0017] When the technician operates the round steel cutting machine to cut the workpiece, it is necessary to perform a process of cutting off the material head, and the material head is waste. If it falls into the same material tray with the processed workpiece, the technician needs to manually check and remove the waste. A discharge opening is provided on the conveying member, and roller mounting seats are provided on both sides of the conveying member. A roller is rotatably provided between the roller mounting seats. A discharge plate is provided on the roller, and the rotation of the discharge plate and the rotating shaft is controlled by the discharge plate control assembly below. When the waste falls on the feed member, the gravity of the waste will be greater than the supporting force of the discharge control assembly, so that the discharge plate rotates to form an opening, which prompts the waste to be diverted. At this time, the technician can set a waste tray under the discharge opening to collect the waste and keep the floor of the workplace clean. When the waste leaves the feed assembly, the supporting force of the discharge plate control assembly is greater than the gravity of the discharge plate, prompting the discharge plate and the rotating shaft to rotate until it is reset. Through this setting, the convenience of users using the round steel cutting machine is improved, the work efficiency is improved, and the user experience is improved.

[0018] The above-mentioned round steel cutting machine can be further configured as follows: a rotation limit assembly is provided on the base, the rotation limit assembly includes a limit seat, the limit seat is fixedly installed on the base, a limit frame is provided on the limit seat, the limit frame is fixedly installed on the limit seat, one end of the first transmission shaft close to the driven wheel extends and is inserted into the limit frame, a rotation limit piece is provided between the driven wheel and the limit frame, the rotation limit piece is rotatably sleeved on the first transmission shaft, and the rotation limit piece is fixedly connected to the driven wheel.

[0019] The above technical solution is adopted, the driving source is a high-power and high-load motor, and the driving source generates power and is transmitted and decelerated by the reduction transmission mechanism. When the reduction transmission mechanism transmits power, the first transmission shaft is in a rotating state, and a first-stage main gear is provided at one end of the first rotating shaft, and a driven wheel is provided at the other end. The driven wheel has a larger gravity, and the first-stage driving wheel is lighter than the driven wheel. When the first rotating shaft is installed on the main machine mounting frame, it is inevitable that it will tilt toward one end of the driven wheel, thereby affecting the rotation of the first transmission shaft. In severe cases, the first transmission shaft may become stuck or detached from the first transmission shaft, which will endanger the user's life safety. By setting a rotation limit assembly, the limit seat is fixedly installed on the base, and a limit frame is provided on the limit seat. The first transmission One end of the shaft extends and is inserted into the limit frame. Through this arrangement, the supporting force of the first transmission shaft at one end of the driven wheel is strengthened, the tilting of the first transmission shaft is avoided, the stability of the round steel cutting machine is improved, and the safety when using the round steel cutting machine is improved; a rotation limiter is provided between the driven wheel and the limit frame, and the rotation limiter is rotatably sleeved on the first rotating shaft, and the rotation limiter is fixedly connected to the driven wheel. Through this arrangement, when the round steel cutting machine is transported or the round steel cutting machine is working, the driven wheel is avoided from sliding along the center axis of the first transmission shaft, thereby causing the driven wheel to collide with other components, causing damage to the driven wheel, and causing the round steel cutting machine to fail to work normally, further improving the working stability of the round steel cutting machine and improving the user experience.

The cutting force is converted from the rotational force generated by the driving source, and a certain thrust will be generated during cutting, which will cause the workpiece to be unstable. By setting a stabilizing component 6, when the round steel cutting machine cuts the workpiece, the adjustable driving source 60 will control the stabilizing clamp component 61 to move until it contacts the workpiece and acts in the opposite direction to the cutting force exerted by the shearing member 51 on the workpiece. Through this design method, the stability of the workpiece is guaranteed when cutting.

[0037] When the round steel cutting machine cuts workpieces of different orders, the sizes of the workpieces to be cut are different, and the user needs to adjust the ejector mechanism 4 to the required position to ensure the dimensional accuracy of the cut workpiece and reduce material waste. Each adjustment requires the user to adjust the ejector mechanism 4 by hand, and the manual method will inevitably produce excessive errors. By setting the ejector drive source 43, the ejector drive source 43 drives the first drive wheel 44 to rotate, and the first drive wheel 44 drives the second drive wheel 48 to rotate through the synchronous belt, thereby driving the screw rod 47 to rotate, and the screw rod 47 controls the flange 49 to rotate, thereby driving the ejector body 405 to move, and the ejector drive source 43 is a servo motor.

[0039] The workpiece cut by the round steel cutting machine has a certain hardness, and the required driving source 2 needs to be a high-power and high-load motor. When using a high-power and high-load motor, the motor power is large and the motor speed will be too fast. By setting a reduction transmission mechanism, the initial speed of the driving wheel driven by the motor is set, and different transmission ratios are set through the reduction transmission mechanism to reduce the speed layer by layer, so that the round steel cutting machine will not produce invalid cutting work while ensuring the cutting force of the round steel cutting machine.

The upper end of the connecting rod 80 is connected to the shearing mechanism 5. The connecting rod 80 drives the shearing mechanism 5 to reciprocate.

[0041] The round steel cutting machine is a device in which a driving source 2 generates a driving force to drive a reduction transmission mechanism to rotate, and the reduction transmission mechanism then drives a linkage assembly and a shearing mechanism 5 to repeatedly perform a cutting motion. As time goes by and the usage time increases, the linkage assembly is inevitably worn. By setting the linkage assembly separately, when the connecting rod 80 or the connecting rod mounting seat 81 is worn or damaged, the linkage assembly can be easily removed by simply disassembling the connecting piece, thereby quickly replacing the linkage assembly, thereby reducing the maintenance and repair costs of the round steel cutting machine.

[0042] After using the round steel cutting machine to cut the workpiece, the technicians will inevitably need to check and maintain the various components and lubricate the components that need lubrication. The linkage assembly is set on the eccentric shaft 731 and needs to rotate and rub continuously during operation. It is an important component that requires regular maintenance. When the user is about to perform lubrication work, he only needs to slightly loosen the connection between the connecting rod 80 and the connecting rod mounting seat 81 to create a small gap, and then pour the lubricating oil in to achieve the purpose of lubrication and maintenance, thereby further reducing the maintenance cost of the round steel cutting machine.

[0043] The round steel cutting machine includes a feeding assembly 9, and the feeding assembly 9 includes a conveying member 90.

The discharge plate control component controls the rotation of the discharge plate 94 and the rotating shaft 93.

[0044] The round steel cutting machine is a fast cutting device. When the user uses the round steel cutting machine to process the workpiece, the processed workpiece will be quickly produced from the round steel cutting machine.

At this time, the technician can set a waste tray under the discharge opening 91 to collect the waste and keep the floor of the workplace clean. When the waste leaves the feeding assembly 9, the supporting force of the discharge plate control assembly is greater than the gravity of the discharge plate 94, prompting the discharge plate 94 and the rotating shaft 93 to rotate until they are reset.

The rotation limit member 12 is rotatably sleeved on the first transmission shaft 70, and the rotation limit member 12 is fixedly connected to the driven wheel 700.

[0047] The driving source 2 is a high-power and high-load motor. After the driving source 2 generates power, it is transmitted and decelerated by the reduction transmission mechanism. When the reduction transmission mechanism transmits power, the first transmission shaft 70 is in a rotating state, and a first-stage main gear 701 is provided at one end of the first rotating shaft 70, and a driven wheel 700 is provided at the other end. The driven wheel 700 has a larger gravity. Compared with the driven wheel 700, the first-stage driving wheel 701 is lighter. When the first rotating shaft 70 is installed on the main mounting frame 3, it is inevitable that it will tilt toward one end of the driven wheel 700, thereby affecting the rotation of the first transmission shaft 70. In severe cases, the first transmission shaft 70 may become stuck or detached from the first transmission shaft 70, which will endanger the user's life safety. By setting a rotation limit assembly, the limit seat 10 is fixedly installed on the base 1, and a limit frame 11 is provided on the limit seat 10.
