[0035] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described 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.

[0036] Reference Figure 1-10The embodiment of the present invention provides a round wire flattening device, comprising a bottom plate 1, side plates 4 are arranged on the left and right sides of the bottom plate 1, a double door 6 and an installation panel 5 are arranged on the front and rear sides of the bottom plate 1, a top plate 7 is arranged on the upper ends of the side plates 4, the installation panel 5 and the double door 6, a liquid storage tank 9 is arranged on the outer side of the installation panel 5, a round wire flattening assembly 10 is arranged in the liquid storage tank 9, the installation panel 5 is fixedly connected to a rod body 1 at one side of the inlet end of the liquid storage tank 9, and the rod body 1 is connected to the rod body 1 via a slewing bearing The mounting panel 5 is screwed to the traction wheel 11 on one side of the outlet end of the liquid storage tank 9, the mounting panel 5 is mounted on the wall below the liquid storage tank 9 with the rod body 2, the rod body 2 is connected to the dividing wheel 13 via a slewing bearing, the mounting panel 5 is screwed to the swing rod 14 below the dividing wheel 13, the end of the swing rod 14 is screwed to the wire pulley 2 15 via a slewing bearing, the reducer 8 is mounted on the inner side of the mounting panel 5, and the output end of the reducer 8 is connected to the traction wheel 11.

[0037] The reducer 8 pulls the traction wheel 11 to rotate, and the round wire passes through the pay-off frame from the wire wheel 12 through the traction wheel 11 and is pulled through the round wire flattening assembly 10 to be drawn into a flat wire of required specifications. The flat wire is wound around the dividing wheel 13, and the dividing wheel 13 is used to prevent the flat wire from being entangled during the movement. Then, it passes through the traction wheel 11 and is wound around the wire wheel 2 15. Finally, it passes through the wire wheel 2 15 to guide the flat wire to the next round wire flattening device for drawing. After multiple drawing, the round wire is drawn into a flat wire of required wire diameter without the need for traditional roller flattening and correction. The processing wire diameter is more stable, the wire drawing speed is faster, and the processing efficiency is greatly improved.

[0038] Reference Figure 2 A drawing liquid tank 2 is installed at the upper end of the bottom plate 1, and a magnetic pump 3 is installed at the upper end of the bottom plate 1 and on the side of the drawing liquid tank 2. One end of the magnetic pump 3 is connected to the drawing liquid tank 2 via pipeline 1, and the other end of the magnetic pump 3 is connected to the liquid storage tank 9 via pipeline 2. The bottom of the liquid storage tank 9 is connected to the upper end of the drawing liquid tank 2 via pipeline 3.

[0039] The drawing liquid in the drawing liquid tank 2 is pumped out by the magnetic pump 3 and sprayed onto the round wire and the flat wire through the pipe, thereby lubricating and cleaning the round wire and cooling the flat wire. The fallen drawing liquid flows back into the drawing liquid tank 2, and the drawing liquid is recycled to save costs.

[0040] Reference Figure 1-4The round wire flattening assembly 10 includes an outer sleeve 101 installed at the outlet end of the liquid storage tank 9, an inner sleeve 102 is engaged in the outer sleeve 101, a round wire flattening block 103 is engaged in the inner sleeve 102, two ends of the round wire flattening block 103 are respectively abutted against the inner sleeve 102 and the outer sleeve 101, an outer sleeve 2 104 is detachably installed on the outer side of the outer sleeve 101, two ends of the inner sleeve 102 are respectively abutted against the outer sleeve 101 and the outer sleeve 2 104, the outer sleeve 2 104 is close to one end of the inlet end of the liquid storage tank 9, wedge-shaped openings 1031 are reserved at both ends of the round wire flattening block 103, and the two wedge-shaped openings 1031 are connected via a square opening 1032.

[0041] The round wire moves through the outer sleeve 104 to the inner sleeve 102, and then moves through the inner sleeve 102 to the round wire flattening block 103, and then enters through the wedge-shaped opening 1031 on one side of the round wire flattening block 103, and then moves out through the wedge-shaped opening 1031 on the other side after being flattened through the square opening 1032, so that the round wire is drawn into a flat wire of required specifications. After multiple drawing, the round wire is drawn into a flat wire of required wire diameter without the need to correct the flat wire, the processing wire diameter is more stable, the wire drawing speed is faster, and the processing efficiency is greatly improved. In addition, a detachable installation method is adopted, which makes it easier to replace components in the round wire flattening assembly 10.

[0042] It should be noted that the specifications of the square opening 1032 can be determined according to the specifications of the flat wire required for production.

[0043] Reference Figure 5-10 The slewing bearing includes a ring 151 and a ring 152. A steel ball 153 is rotatably arranged between the ring 151 and the ring 152. An assembly seat 154 is arranged outside the steel ball 153. The assembly seat 154 is used to maintain the distance between the steel balls 153. A storage groove 155 is reserved in the assembly seat 154 between the pair of steel balls 153. The storage groove 155 is filled with engine oil. A groove 156 connected to the storage groove 155 is reserved inside the assembly seat 154. The discharge port of the groove 156 is arranged toward the steel ball 153.

[0044] When the slewing bearing is running low on oil, the temperature will continue to rise as it rotates, and the oil in the storage tank 155 can flow onto the steel ball 153 through the groove 156;

[0045] The guide wheel 12, the dividing wheel 13 and the guide wheel 2 15 work continuously, resulting in a large loss of oil in the slewing bearing. The slewing bearing needs to be inspected and oiled regularly. If the inspection or oiling is not timely, after the oil loss in the slewing bearing ends or decreases to a certain range, the obstruction between the steel ball 153 and the ring 151 and the ring 2 152 will increase sharply, which will cause a large amount of heat to be generated in the slewing bearing. If the oil cannot be injected on time, the slewing bearing will be damaged, which will cause the guide wheel 12, the dividing wheel 13 and the guide wheel 2 15 to be unable to be used normally, thereby causing the device to be unusable and reducing production efficiency.

[0046] Inject oil into the storage groove 155 on the assembly seat 154. When the guide wheel 12, the dividing wheel 13 and the guide wheel 2 15 rotate and heat up due to less oil, the oil in the storage groove 155 can flow to the steel ball 153 through the groove 156, thereby preventing the slewing bearing from being damaged due to continuous action and temperature rise, thereby ensuring the life of the slewing bearing, that is, extending the use time of the slewing bearing that is injected with oil by itself. If the time limit for injecting oil is exceeded, the slewing bearing will not be damaged due to lack of oil, and the time limit for injecting oil beyond the deadline can be given to the employees. Therefore, although the slewing bearing can be injected with oil by itself, the installation of self-injection of oil can add a guarantee for the slewing bearing.

[0047] A composite sheet 157 is arranged inside the storage groove 155. The outer wall of the composite sheet 157 can block the entrance of the groove 156 at one end of the storage groove 155. Under the condition of no temperature increase, the composite sheet 157 changes its shape and presses on the entrance of the groove 156. Even if the slewing bearing rotates with oil, the slewing bearing will still heat up. The composite sheet 157 changes its shape and presses on the entrance of the groove 156. When the composite sheet 157 heats up, the shape of the composite sheet 157 changes. However, the degree of shape change of the composite sheet 157 is not enough to allow the copper sheet 1572 to leave the entrance of the groove 156.

[0048] The composite sheet 157 includes a steel sheet 1571 and a copper sheet 1572 , and the expansion coefficient of the steel sheet 1571 is smaller than the expansion coefficient of the copper sheet 1572 .

[0049] The vertical span of the steel sheet 1571 is smaller than the vertical span of the copper sheet 1572. Only the copper sheet 1572 is installed at the position where the composite sheet 157 and the wall of the storage tank 155 are in contact. When the copper sheet 1572 is directly in contact with the inner wall of the storage tank 155, there is no bending at the position where the copper sheet 1572 and the inner wall of the storage tank 155 are in contact. The segment of the composite sheet 157 on which only the copper sheet 1572 is installed is equivalent to a leak-proof block. If the structure of the leak-proof block is unstable and prone to shape changes, the leak-proof performance of the leak-proof block (that is, the segment on which only the copper sheet 1572 is installed) at the entrance of the ditch 156 will be weakened. By preventing the shape of the segment on which only the copper sheet 1572 is installed from changing, the purpose of blocking the entrance of the ditch 156 by the copper sheet 1572 can be achieved.

[0050] The outer wall of the copper sheet 1572 at the entrance of the groove 156 is fixedly connected to the leak-proof sheet 1573, and the inner wall surface of the storage groove 155 is fixedly connected to the conductive sheet 158. The composite sheet 157 is fixedly connected to the inner surface of the storage groove 155 through the conductive sheet 158. When the slewing bearing rotates and the temperature rises due to the lack of engine oil, the resistance between the steel ball 153 and the assembly seat 154 rises and the heat is transferred to the composite sheet 157. Since the expansion coefficient of the steel sheet 1571 is smaller than the expansion coefficient of the copper sheet 1572, the composite sheet 157 will bend toward the center of the storage groove 155. After the composite sheet 157 is bent, the composite sheet 157 opens the entrance of the groove 156. At this time, the engine oil in the storage groove 155 can flow through the groove 156. The heat flows onto the steel ball 153 to achieve the purpose of maintaining the slewing bearing. Among them, the inner wall of the storage tank 155 is fixedly connected to the conductive sheet 158, and the composite sheet 157 is fixedly connected to the inner wall of the storage tank 155 via the conductive sheet 158. This method can prevent the segment of the composite sheet 157 that can be bent by heat from being attached to the inner wall of the storage tank 155, thereby achieving the purpose of keeping the heat transfer direction of the composite sheet 157 unchanged. Since the heat transfer performance of the leakproof sheet 1573 is relatively weak, the heat energy of the assembly seat 154 is transferred to the middle area of ​​the composite sheet 157 via the conductive sheet 158. The middle area of ​​the composite sheet 157 is heated first, and then the middle area of ​​the composite sheet 157 is bent first. This structure can make the composite sheet 157 better at opening and closing the entrance of the channel 156;

[0051] A corrugated pipe 159 is fixedly connected to the inner wall of the storage tank 155 , and a closed chamber is formed between the mouth of the lower end of the corrugated pipe 159 and the fixed area of ​​the inner wall of the storage tank 155 , and the upper end of the corrugated pipe 159 is fixedly connected to the lead platform 1510 .

[0052] A spiral beryllium copper wire 1511 is fixedly connected between the inner side of the upper end of the corrugated pipe 159 and the inner wall of the storage tank 155.

[0053] The inside of the bellows 159 is filled with air of one half of the volume when the bellows 159 is stretched to its longest position. Since the air pressure of the airflow inside the bellows 159 will be lower than the external air pressure during the stretching period, the chamber inside the bellows 159 is filled with air of one half of the volume when the bellows 159 is stretched to its longest position in advance. The air inside the bellows 159 is concentrated by the pressure of the engine oil in the storage tank 155. In the subsequent extension process of the bellows 159, the obstruction of the low pressure that the bellows 159 is subjected to when extending can be reduced.

[0054] The inner side of the corrugated pipe 159 with the longest radius is fixedly connected with a reinforcing ring 1512. By installing the reinforcing ring 1512, the stability of the corrugated pipe 159 structure can be enhanced.

[0055] The assembly seat 154 is made of aluminum alloy, and the aluminum alloy assembly seat 154 has a good heat transfer function.

[0056] When the slewing bearing rotates, the assembly seat 154 will rotate along with it, and the rotation of the assembly seat 154 will generate a pulling force toward the center of rotation. The lead platform 1510 compresses the engine oil in the storage tank 155 under the cooperation of the pulling force of the rotation center. If the lead platform 1510 changes, the lead platform 1510 will pull the corrugated pipe 159 to extend, and the extension of the corrugated pipe 159 will occupy the entire space of the storage tank 155, thereby increasing the pressure strength of the engine oil in the storage tank 155. When the composite sheet 157 and the inlet of the groove 156 are separated, the engine oil will be pressed out through the groove 156 under the pressure of the engine oil, and the amount of engine oil in the storage tank 155 will decrease. When the inlet of the groove 156 is blocked by the composite sheet 157, the lead platform 1510 will be pulled by the installed spiral beryllium copper wire 1511, which can prevent the lead platform 1510 from shaking violently inside the storage tank 155.
