Description

Technical Field

[0002] Wire cutting machine is a kind of precision processing equipment which uses the principle of electric spark discharge to cut metal materials. It is mainly used to process complex shapes and thin-walled parts with high precision requirements. The parts (moving mechanism, etc.) on the large taper mechanism of existing wire cutting machine are all located on one side of the column, and a lead screw for driving the large taper mechanism to move is provided in the column of the wire cutting machine. This causes the force of the large taper mechanism on the column lead screw to be excessively deflected. During long-term use, the side of the column lead screw close to the large taper mechanism is severely worn, resulting in errors in the accuracy of the transmission distance of the transmission lead screw. At the same time, when the large taper mechanism is adjusted in height, it will cause the center of gravity of the column to shift (that is, the higher the large taper mechanism, the greater the bending force on the column and the lead screw thereon). In severe cases, the column will bend and deform, which will cause the workpiece cutting accuracy to fail to meet the standard. Summary of the invention

During long-term use, the side of the column screw close to the large taper mechanism is severely worn, resulting in errors in the accuracy of the transmission distance of the transmission screw. At the same time, when the height of the large taper mechanism is adjusted, it will cause the center of gravity of the column to shift (that is, the higher the large taper mechanism, the greater the bending force on the column and the screw thereon).

The rotating rod 9 is provided with a guide wheel wire frame. The guide wheel wire frame is a prior art and is used to control the inclination of the cutting line. No more details are given here.

[0020] like Figure 2 and Figure 5-Figure 7As shown, the deviation detection mechanism 17 includes a fixed frame 1701, which is composed of two L-shaped rods and a circular ring distributed in a mirror image. The fixed frame 1701 is fixed to the upper side of the fixed frame 7. The inner side of the circular ring of the fixed frame 1701 is fixed with a detection sleeve 1702. The detection sleeve 1702 is made of elastic material. The detection sleeve 1702 is squeezed and matched with the cooperative rod 12 to monitor the deflection of the cooperative rod 12 in real time. The circular ring of the fixed frame 1701 slides on the The four detection rods 1703 are connected to the fixed frame 1701 and are arranged in a circumferential array.

The second fixed shell 1707 is sealed and slidably connected to a first piston rod 1708 fixed to the adjacent extrusion plate 16.

[0021] When it is necessary to use this device to perform wire cutting processing on a workpiece, the user first adjusts the distance between the two guide wheel wire racks according to the thickness of the workpiece. The specific operation is as follows: the user controls the rotation of the screw on the column 5 through an external power source, and the screw on the column 5 drives the support frame 6, the counterweight box 13 and the parts thereon to move upward with a thread until they move to a suitable position. The user controls the screw on the column 5 to stop rotating. At this time, the position adjustment of the guide wheel wire rack is completed. During the above-mentioned movement process, the direction of the force between the support frame 6 and the screw on the column 5 is balanced by the counterweight box 13 and the parts thereon, and the forces acting on the screw on the column 5 by the support frame 6 and the counterweight box 13 are equal in magnitude and in opposite directions, thereby preventing the screw on the column 5 from being worn on one side.

[0022] After the position adjustment of the guide wheel wire rack is completed, the user controls the second sliding frame 3 and the base 4 to jointly drive the column 5, the support frame 6 and the parts thereon to move according to the required processing shape of the workpiece, so that the cutting line between the two guide wheel wire racks is deflected to meet the processing requirements. Taking the cutting line deflecting to the right from bottom to top as an example, the user drives the lead screw on the first sliding frame 2 to rotate through an external power, and the lead screw on the first sliding frame 2 drives the second sliding frame 3, the base 4, the column 5 and the support frame 6 to move to the right through the thread, and the support frame 6 drives the fixed tube 8 and the rotating rod 9 to move to the right together, and the rotating rod 9 drives the upper side The guide wheel wire frame moves to the right, and the upper guide wheel wire frame swings to the left relative to the adjacent fixed tube 8 under the drive of the upper cooperative block 11 (the lower guide wheel wire frame swings in the opposite direction), thereby causing the cutting line between the two guide wheel wire frames to deviate, and then the workpiece is cut, and the first sliding frame 2 and the second sliding frame 3 are removed from the support frame 6, so that the gravity of the support frame 6 itself is reduced, thereby reducing the force of the support frame 6 on the column 5 and the upper screw, preventing the support frame 6 from being too heavy and causing the upper screw of the column 5 to bear too much pressure on one side, thereby extending the service life of the upper screw of the column 5 and improving the accuracy of the processed workpiece.

[0023] When adjusting the swing position of the upper guide wheel wire frame as mentioned above, the upper rotating rod 9 drives the upper cooperative block 11 to move synchronously to the right through the upper fixed block 10, so that the cooperative rod 12 is synchronously deflected, and the deflection of the cooperative rod 12 is the same as the deflection of the cutting line. When the upper guide wheel wire frame swings and deflects, the average center of gravity of the support frame 6 and the parts thereon will be synchronously offset, thereby causing the force of the support frame 6 on the lead screw on the column 5 to change in magnitude and direction. In the long run, the lead screw on the column 5 will also be worn to different degrees, thereby affecting the moving accuracy of the lead screw on the column 5 and affecting the processing accuracy of the device on the workpiece. To solve the above problem, the following operations need to be performed: During the processing of the workpiece, when the cooperative rod 12 is deflected (taking the cooperative rod 12 deflecting to the right from bottom to top as an example), the cooperative rod 12 squeezes and drives the right side of the detection sleeve 1702 to move to the right synchronously, and the detection sleeve 1702 drives the right detection rod 1703 to move to the right, and the right detection rod 1703 drives the right piston plate 1704 to move to the right. At the same time, the hydraulic oil in the right first fixed shell 1705 moves to the left second fixed shell 1707 through the pipeline, and the hydraulic oil in the left second fixed shell 1707 squeezes and drives the left first piston rod 1708 to move downward, and the left first piston rod 1708 drives the left extrusion plate 16 to move downward, thereby squeezing the water in the water storage bag 15 on the lower side of the left extrusion plate 16 to the right side of the water storage bag 15, thereby synchronously adjusting the center of gravity of the counterweight box 13, and in the above process, the left detection rod The movement of 1703 is opposite to that of the right detection rod 1703, thereby driving the right extrusion plate 16 to move upward, and synchronously assisting the water in the water storage bag 15 to move to the right, thereby adjusting the center of gravity position of the counterweight box 13, so that the magnitude and direction of the force exerted by the counterweight box 13 and its parts on the screw on the column 5 are synchronously adjusted with the magnitude and direction of the force exerted by the support frame 6 and its parts on the screw on the column 5, so as to offset the fluctuation of the force between the support frame 6 and the screw on the column 5 in real time, and judge the change of the center of gravity of the support frame 6 by detecting the degree of deflection of the cooperative rod 12, and adjust the center of gravity of the counterweight box 13 and its parts in real time according to the change of the center of gravity of the support frame 6, so that the screw on the column 5 is always in a tight balance state under force, so as to prevent the screw on the column 5 from wearing to different degrees, thereby affecting the processing accuracy of the workpiece.

[0024] When the device is used, the user controls the column 5 to drive the support frame 6 and the parts thereon to move to the left and reset, the coordinated rod 12 drives the detection sleeve 1702 to reset, the detection sleeve 1702 drives the left and right side piston plates 1704 to reset at the same time, and the oil circuit reflux drives the four extrusion plates 16 to reset, thereby restoring the center of gravity of the water storage bag 15.

[0025] During the cutting process of the workpiece, the user needs to use coolant to flush the cut metal debris and cool the cut surface of the workpiece. During this process, the coolant is always wrapped around the cutting line. When performing conical surface processing, since the cutting line is cut in an inclined state, if the coolant flow rate is too slow, under the influence of gravity, the coolant flow path will be deviated from the cutting line, causing the coolant to lose its wrapping around the cutting line, thereby affecting the cooling effect of the coolant on the cut surface of the workpiece and reducing the processing accuracy of the workpiece surface.

[0026] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 5 and Figure 8-Figure 10As shown, it also includes a pressure-compensating mechanism 18 for adjusting the cooling fluid pressure.

The booster pump 1801 is fixedly connected to the rear side of the support frame 6. A pipeline connected to the external cooling fluid supply system is arranged on the upper side of the booster pump 1801. The booster pump 1801 is connected to the cooling fluid system on the guide wheel wire frame of the upper rotating rod 9 through the pipeline. The front side of the fixed frame 7 is fixedly connected to the second fixed plate 180 2. A transfer frame 1803 is fixedly connected to the upper side of the second fixed plate 1802. A sliding sleeve 1804 is slidably connected to the transfer frame 1803. The sliding sleeve 1804 is electrically connected to the booster pump 1801 through the transfer frame 1803. When the sliding sleeve 1804 is located at the rightmost side of the transfer frame 1803, the output power of the booster pump 1801 is the maximum. On the contrary, when the sliding sleeve 1804 is located at the leftmost side of the transfer frame 1803, the output power of the booster pump 1801 is the minimum. A third fixed shell 1805 is fixedly connected to the front side of the lower side coordination block 11 through a mounting frame. The third fixed shell 1805 The third fixed shell 1805 is sealed and slidably connected with the second piston rod 1806, and the second piston rod 1806 is fixedly connected to the upper cooperative block 11 through the mounting plate. The upper side of the second fixed plate 1802 is fixedly connected with the fourth fixed shell 1807, and the fourth fixed shell 1807 is filled with hydraulic oil. The third fixed shell 1805 is connected with the fourth fixed shell 1807 through a pipeline, and the pipeline between the two is an elastic and retractable pipeline. The fourth fixed shell 1807 is sealed and slidably connected with the third piston rod 1808, and the right side of the third piston rod 1808 is connected to the sliding sleeve 1804. Four hydraulic telescopic rods 1809 are arranged equidistantly on the left side, the third piston rod 1808 is fixedly connected to the fixed part of the leftmost hydraulic telescopic rod 1809, the sliding sleeve 1804 is fixedly connected to the telescopic end of the rightmost hydraulic telescopic rod 1809, and the fixed parts and telescopic ends of adjacent hydraulic telescopic rods 1809 are fixedly connected to each other, the four hydraulic telescopic rods 1809 correspond one by one to the first fixed shells 1705 distributed in a circumferential array, and the corresponding fixed parts of the hydraulic telescopic rods 1809 are connected to the first fixed shell 1705 through pipes, and the pipes are all elastic and telescopic pipes.

[0027] When adjusting the distance between the two guide wheel wire frames, the upper cooperative block 11 drives the second piston rod 1806 to move upward through the mounting plate, and the hydraulic oil in the third fixed shell 1805 flows through the pipeline to the fourth fixed shell 1807 under the extrusion of the second piston rod 1806, and the hydraulic oil is squeezed in the fourth fixed shell 1807 and drives the third piston rod 1808 and the four hydraulic telescopic rods 1809 to move to the right together, and the third piston rod 1808 and the four hydraulic telescopic rods 1809 drive the sliding sleeve 1804 to move to the right, and the sliding sleeve 1804 increases the power of the boost pump 1801 through the transfer frame 1803, thereby increasing the flow rate of the coolant until the distance between the two guide wheel wire frames is adjusted.

[0028] When cutting the workpiece, the user starts the booster pump 1801, and the booster pump 1801 transports the coolant in the cooling system to the cooling pipe of the upper guide wheel wire rack through the pipeline.
