Description

Technical Field

[0001] The present invention belongs to the technical field of machining equipment, and particularly refers to a new type of die steel sawing equipment. Background Art

[0002] Die steel is a steel type used to manufacture dies such as cold stamping dies, hot forging dies, and die-casting dies. Dies are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances. A sawing machine is the main mechanical equipment used to process die steel. The guiding device for adjusting the orientation of the saw teeth on the saw blade of a sawing machine is an important mechanism that affects the precision of the die steel cut by the sawing machine. However, the guiding devices of sawing machines on the market currently have deficiencies. For example, in Chinese Patent: CN214349992U, the saw blade first passes through the gap between two guiding wheels, and then after passing through the gap between two alloy blocks, the orientation of the saw teeth on the saw blade will change. However, since the two guiding wheels are fixed on the guiding head body, when the saw blade enters between the two guiding wheels, a large torsion needs to occur, resulting in a large torsion force on the saw blade. Over time, not only is the saw blade prone to breakage, but also the friction between the saw blade and the guiding wheels increases, accelerating the wear of the guiding wheels and shortening the service life of the guiding wheels. Moreover, in order to ensure that the saw blade does not shake left and right during the cutting process, in the above-mentioned sawing machine, after the saw blade enters the gap between the two alloy blocks, it is necessary to rotate the adjusting bolt so that one end of the adjusting bolt abuts against the alloy block on one side of the guide block mechanism. The middle thread of the adjusting bolt drives one end of the adjusting bracket, and the other end of the adjusting bracket abuts against the alloy block on the other side of the guide block mechanism in the opposite direction, so that the two alloy blocks simultaneously contact the saw blade. This rotation of the adjusting bolt requires manual adjustment by workers, which is not only troublesome but also time-consuming and laborious. Summary of the Invention

[0003] The purpose of the present invention is to provide a new type of die steel sawing equipment with a simple structure, which can reduce the torsion force that the saw blade needs to bear during the process of changing the orientation, increase the service life of the saw blade, and enable workers to drive the clamping piece to move towards the side of the saw blade by controlling the clamping cylinder to work, so that the clamping piece fits with the saw blade, with a higher degree of automation, and there is no need for the user to manually control the movement of the clamping piece, which is convenient and fast.

[0017] The prominent and beneficial technical effects of the present invention compared with the prior art are:

[0018] The present invention belongs to the technical field of machining equipment, and particularly refers to a new type of die steel sawing equipment, which includes a machine base, a guiding column arranged on the machine base, a saw frame movably arranged up and down on the guiding column, a sawing mechanism arranged on the saw frame, and a first driving device for controlling the up and down movement of the saw frame along the guiding column. The clamping device on the machine base consists of a fixed jaw, a movable jaw, and a second driving device. There is a feeding device and a third driving device on the machine base. When the third driving device works, it will drive the feeding device to move, so that the feeding device transports the die steel between the fixed jaw and the movable jaw. At this time, when the first driving device works, it will drive the movable jaw to move towards the fixed jaw, so that the die steel is clamped under the mutual cooperation of the movable jaw and the fixed jaw, ensuring that the die steel does not move during the cutting process and guaranteeing the normal progress of the cutting work. The sawing mechanism on the saw frame includes a driven wheel rotatably arranged on the saw frame, a driving wheel, and a saw blade wound around the driven wheel and the driving wheel. When the die steel is clamped, the fourth driving device on the saw frame will control the driving wheel to rotate. After the driving wheel rotates, it will drive the saw blade to rotate. And the first driving device will control the overall downward movement of the saw frame. At the same time, the sawing mechanism will also move downward with the saw frame. Since the sawing mechanism is directly below the clamping device, when the sawing mechanism moves downward, the saw blade will cut the die steel. When the worker wants to adjust the tightness of the saw blade, at this time, because there is a rotating shaft in the waist-shaped hole on the saw frame, and the rotating shaft is connected to the driven wheel. There is a mounting seat on the back of the saw frame, and a driving seat is slidably arranged on the mounting seat. The driving seat is connected to one end of the rotating shaft. The other end of the rotating shaft is connected with a synchronous plate, and the synchronous plate is connected to the connecting part on the driving seat. The worker can drive the driving seat to move relative to the mounting seat by controlling the fifth driving device on the mounting seat. When the driving seat moves, it will drive one end of the rotating shaft to move along the waist-shaped hole. At this time, the connecting part on the driving seat will also move synchronously. After the connecting part moves, it will drive the synchronous plate to move. And the movement of the synchronous plate will drive the other end of the rotating shaft to move along the waist-shaped hole, so that the whole rotating shaft moves horizontally along the waist-shaped hole, and the angle of the rotating shaft will not shift during the movement. As a result, the angle of the driven wheel connected to the rotating shaft will not shift during the movement. Finally, driven by the fifth driving device, the driven wheel will move away from or close to the driving wheel. When the driven wheel moves away from the driving wheel, the saw blade wound around the driving wheel and the driven wheel will be tightened. On the contrary, the saw blade will be in a loose state, enabling the worker to adjust the tightness of the saw blade according to the actual situation, so that the quality of the cut die steel will not be affected, and the appropriate tightness of the saw blade can ensure the service life of the saw blade, thus avoiding the situation that the saw blade breaks during use and endangers the safety of the worker. There are a first guiding seat and a second guiding seat on the saw frame. The first guiding seat and the second guiding seat are symmetrically arranged and located between the driving wheel and the driven wheel. The saw blade rotates towards the side of the first guiding column. And because there are guiding wheels symmetrically arranged on the first guiding seat,The second guide seat is provided with a fixed guide wheel and an eccentric guide wheel, and the saw blade is located between the fixed guide wheel, the eccentric guide wheel and the symmetrical guide wheel and in the guide groove of the first guide seat and the second guide seat, thereby changing the direction of the saw teeth on the saw blade, and since the rotating rod on the eccentric guide wheel is rotatably arranged in the movable groove of the second guide seat, the eccentric guide wheel can be rotated relative to the second guide seat through the rotating rod. When the saw blade rotates toward the side of the first guide column, the saw blade needs to pass through the fixed guide wheel and the eccentric guide wheel first, and the saw blade will twist. At this time, the saw will exert force on the eccentric guide wheel. The eccentric guide wheel is deflected outwards by a certain angle by adding a thrust, and the saw blade can enter the guide groove of the second guide seat more naturally without a large twist, thereby reducing the torque that the saw blade has to bear when twisting, and increasing the service life of the saw blade. The friction between the saw blade and the eccentric guide wheel and the fixed guide wheel is also greatly reduced, so that the wear rate of the eccentric guide wheel and the fixed guide wheel is reduced, and the situation that workers frequently replace the guide wheels is avoided. Moreover, since the top end of the rotating rod abuts against the elastic member in the movable groove, the elastic member will always apply an outward thrust to the top end of the rotating rod, thereby Ensure that the eccentric guide wheel at the bottom end of the rotating rod can always contact the side of the saw blade, so that the saw blade remains stable during the cutting process, reducing inaccurate cutting caused by saw blade deviation or vibration, thereby improving cutting efficiency, and the guide grooves of the first guide seat and the second guide seat are both provided with clamping pieces, which can fit with the side of the saw blade, and the clamping cylinders on the first guide seat and the second guide seat are both provided with drive shafts, the drive shaft of the clamping cylinder on the first guide seat passes through the first guide seat and enters into the guide groove and is connected to the clamping piece, the drive shaft of the clamping cylinder on the second guide seat passes through the second guide seat and enters into the guide groove and is connected to the clamping piece The clamping plate is connected to the inside of the groove. The clamping cylinder is a common air cylinder or oil cylinder on the market. The worker can control the clamping cylinder to move the drive shaft outward, thereby driving the clamping plate to move toward the side of the saw blade, so that the clamping plate fits the saw blade. At this time, the two sides of the saw blade fit with the clamping plate and the side of the guide groove respectively, thereby ensuring that the saw blade 1 will not shake left and right during the process of cutting the mold steel, ensuring the accuracy of the cut mold steel. In addition, this method of using an air cylinder or oil cylinder to control the movement of the saw blade has a higher degree of automation and does not require the user to manually control the movement of the clamping plate, which is convenient and fast.

[0066] The present invention will be further described below in conjunction with specific embodiments:

[0067] The present invention belongs to the technical field of machining equipment, and particularly refers to a new type of die steel sawing equipment, which includes a machine base 1, a guide post 2 arranged on the machine base 1, a saw frame 3 movably arranged up and down on the guide post 2, a sawing mechanism arranged on the saw frame 3, and a first driving device 4 for controlling the up and down movement of the saw frame 3 along the guide post 2. The clamping device 5 on the machine base 1 consists of a fixed jaw 6, a movable jaw 7, and a second driving device 8. There is a feeding device 80 and a third driving device 9 on the machine base 1. When the third driving device 9 works, it will drive the feeding device 80 to move, so that the feeding device 80 transports the die steel between the fixed jaw 6 and the movable jaw 7. At this time, when the first driving device 4 works, it will drive the movable jaw 7 to move towards the fixed jaw 6, so that the die steel is clamped under the cooperation of the movable jaw 7 and the fixed jaw 6, ensuring that the die steel does not move during the cutting process and guaranteeing the normal progress of the cutting work. The sawing mechanism on the saw frame 3 includes a driven wheel 10 rotatably arranged on the saw frame 3, a driving wheel 11, and a saw blade 12 wound around the driven wheel 10 and the driving wheel 11. When the die steel is clamped, the fourth driving device 13 on the saw frame 3 will control the driving wheel 11 to rotate. After the driving wheel 11 rotates, it will drive the saw blade 12 to rotate. And the first driving device 4 will control the overall downward movement of the saw frame 3. At the same time, the sawing mechanism will also move downward with the saw frame 3. Since the sawing mechanism is directly below the clamping device 5, when the sawing mechanism moves downward, the saw blade 12 will cut the die steel. When the worker wants to adjust the tightness of the saw blade 12, at this time, because there is a rotating shaft 15 in the waist-shaped hole 14 on the saw frame 3, and the rotating shaft 15 is connected to the driven wheel 10. There is a mounting seat 16 on the back of the saw frame 3, and a driving seat 17 is slidably arranged on the mounting seat 16. The driving seat 17 is connected to one end of the rotating shaft 15. The other end of the rotating shaft 15 is connected to a synchronous plate 19, and the synchronous plate 19 is connected to the connecting part 81 on the driving seat 17. The worker can drive the driving seat 17 to move relative to the mounting seat 16 by controlling the fifth driving device 18 on the mounting seat 16 to work. When the driving seat 17 moves, it will drive one end of the rotating shaft 15 to move along the waist-shaped hole 14. At this time, the connecting part 81 on the driving seat 17 will also move synchronously. After the connecting part 81 moves, it will drive the synchronous plate 19 to move, and the movement of the synchronous plate 19 will drive the other end of the rotating shaft 15 to move along the waist-shaped hole 14, so that the rotating shaft 15 as a whole moves horizontally along the waist-shaped hole 14, and the angle of the rotating shaft 15 will not shift during the movement process, so that the angle of the driven wheel 10 connected to the rotating shaft 15 will not shift during the movement process. Finally, driven by the fifth driving device 18, the driven wheel 10 will move away from or close to the driving wheel 11. When the driven wheel 10 moves away from the driving wheel 11, the saw blade 12 wound around the driving wheel 11 and the driven wheel 10 will be tightened. On the contrary, the saw blade 12 will be in a loose state, enabling the worker to adjust the tightness of the saw blade 12 according to the actual situation.Thus, the quality of the cut die steel will not be affected, and the appropriate tightness of the saw blade 12 can ensure the service life of the saw blade 12, thus avoiding the situation where the saw blade 12 breaks during use and endangers the safety of workers. There are a first guide seat 20 and a second guide seat 21 on the saw frame 3. The first guide seat 20 and the second guide seat 21 are symmetrically arranged and located between the driving wheel 11 and the driven wheel 10. The saw blade 12 rotates towards the first guide post 2. Since there are symmetrically arranged guide wheels 22 on the first guide seat 20, and a fixed guide wheel 23 and an eccentric guide wheel 24 on the second guide seat 21, the saw blade 12 is located between the fixed guide wheel 23, the eccentric guide wheel 24 and the symmetrically arranged guide wheels 22, as well as in the guide channels 28 of the first guide seat 20 and the second guide seat 21, thus changing the orientation of the saw teeth on the saw blade 12. And since the rotating rod 27 on the eccentric guide wheel 24 is rotatably arranged in the movable slot 25 of the second guide seat 21, the eccentric guide wheel 24 can rotate relative to the second guide seat 21 through the rotating rod 27. When the saw blade 12 rotates towards the first guide post 2, the saw blade 12 needs to pass through the fixed guide wheel 23 and the eccentric guide wheel 24 first, and the saw blade 12 will twist. At this time, the saw blade 12 will exert a thrust on the eccentric guide wheel 24, causing the eccentric guide wheel 24 to deflect outward by a certain angle. At this time, the saw blade 12 can enter the guide channel 28 of the second guide seat 21 more naturally without undergoing a large twist, thus reducing the torque that the saw blade 12 needs to bear during twisting, increasing the service life of the saw blade 12, and greatly reducing the friction between the saw blade 12 and the eccentric guide wheel 24 and the fixed guide wheel 23, reducing the wear rate of the eccentric guide wheel 24 and the fixed guide wheel 23, and avoiding the situation where workers often replace the guide wheel 22. And since the top end of the rotating rod 27 abuts against the elastic member 26 in the movable slot 25, the elastic member 26 will always exert an outward thrust on the top end of the rotating rod 27, thus ensuring that the eccentric guide wheel 24 located at the bottom end of the rotating rod 27 can always be in contact with the side surface of the saw blade 12, keeping the saw blade 12 stable during cutting, reducing inaccurate cutting caused by the deviation or vibration of the saw blade 12, and thus improving the cutting efficiency. The guide channels 28 of the first guide seat 20 and the second guide seat 21 are both provided with clamping pieces 29, and the clamping pieces 29 can be attached to the side surface of the saw blade 12. There are driving shafts 31 on the clamping cylinders 30 on the first guide seat 20 and the second guide seat 21.
