Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wire cutting devices, and particularly relates to a double-station wire cutting device for medical springs. BACKGROUND

[0002] The wire cutting technology is a relatively advanced silicon material processing technology in the world at present, and its principle is that a cutting blade attached to a steel wire is driven by the high-speed running steel wire or a diamond wire is directly used to rub a workpiece to be processed, so that the purpose of wire cutting is achieved. In the cutting process, the steel wire or the diamond wire is guided by a guide wheel, and a wire saw or a wire mesh is formed on a cutting roller, and the workpiece to be processed is fed by the upward and downward movement or the forward and backward movement of a workbench.

[0003] In the prior art, the wire cutting device has the following defects: 1. Most of the existing wire cutting devices have only one wire. When a group of medical springs needs to be cut into three sections, the wire cutting device needs to be operated twice to achieve the purpose. However, the error range of medical spring cutting is usually controlled within + / - 0.1 mm. The intermittent cutting operation is easy to produce greater deviation, so that the medical springs produced by cutting have an increased waste rate, and the processing cost is increased.

[0004] 2. The existing wire cutting device generally does not have a collecting mechanism. The objects completed by wire cutting are left on the machining table, and the workers need to manually collect them. However, the medical springs will move or bounce slightly on the workbench due to their own characteristics, so that the medical springs will fall in various places on the machining table, increasing the difficulty of collection and affecting the overall work efficiency.

[0048] It should be noted that the spring clamping mechanism 604 is two sets of clamping plates arranged vertically, a clamping space matching the medical spring is arranged between the two sets of clamping plates, and the upper clamping plate is arranged on the lower clamping plate through a lifting cylinder, so that the lifting cylinder drives the upper clamping plate to move up and down, and then the medical spring can be clamped and fixed between the two sets of clamping plates or lose the clamping and fixing effect on the medical spring. Because this structure is a common technology, it will not be described in detail, and when feeding, the medical spring to be cut will be pushed horizontally forward into the interior of the spring clamping mechanism 604 from the rear side of the spring clamping mechanism 604, the arrangement of the two collecting boxes 8 can collect the front and back two sections cut from the medical spring respectively, then after the new medical spring to be cut is pushed horizontally into the interior of the spring clamping mechanism 604, the remaining section of the medical spring will be pushed out of the spring clamping mechanism 604, so as to fall into the front collecting box 8.

[0049] The material collecting mechanism 7 comprises a guide plate one 701 and a guide plate two 702, and the guide plate one 701 and the guide plate two 702 are arranged on the front and back of the spring clamping mechanism 604 respectively, the lower ends of the guide plate one 701 and the guide plate two 702 are fixedly connected with the upper ends of the two collecting boxes 8 respectively, the arrangement of the guide plate one 701 and the guide plate two 702 can smoothly guide the cut medical springs into the interiors of the corresponding collecting boxes 8, the left and right sides of the guide plate one 701 are slidably installed in the interiors of the two connecting plates 603 through the moving block four 715, the left and right sides of the guide plate two 702 are fixedly connected with the inner side walls of the two connecting plates 603 respectively, the interior of the guide plate one 701 is movably connected with a vibrating plate 704 through a reset spring 703, the middle of the inner surface of the vibrating plate 704 is provided with an abutting plate 705, the rear end of the abutting plate 705 abuts against a circular hollow plate 706, and the circumferential outer surface of the circular hollow plate 706 is arrayed with eight arc convex plates 723, so that when the circular hollow plate 706 rotates, the arc convex plate 723 abuts against the abutting plate 705, the vibrating plate 704 can be pushed forward through the abutting plate 705, and when the arc convex plate 723 does not contact the abutting plate 705, the vibrating plate 704 moves back to reset through the reset spring 703, at the same time, the abutting plate 705 moves back and abuts against the recess on the outer surface of the circular hollow plate 706, wherein the rear end of the abutting plate 705 is arc-shaped on the upper and lower sides, so that when the circular hollow plate 706 drives the arc convex plate 723 to rotate, the arc convex plate 723 can smoothly push the abutting plate 705 to move forward, the interior of the circular hollow plate 706 is provided with a rotating rod 707, the rear end of the rotating rod 707 penetrates through the rear side of the guide plate one 701 and is connected with a worm wheel 708, the lower end of the worm wheel 708 is meshedly connected with a worm 709, the interior of the worm 709 is inserted with a cross rotating rod 710, the front and rear ends of the cross rotating rod 710 are provided with a rotating shaft two 712 and a rotating shaft one 711 respectively, and the rotating shaft two 712 and the rotating shaft one 711 are rotatably installed in the interior of the left connecting plate 603, the arrangement of the cross rotating rod 710 makes the rotating shaft two 712 rotate, which can drive the worm 709 to rotate through the cross rotating rod 710, and the worm 709 can move forward and backward on the cross rotating rod 710 at the same time, the circumferential surface of the front end of the rotating shaft two 712 is provided with a straight gear 713, the circumferential surface of the rear end of the worm 709 is provided with a mounting block 714, and the worm 709 is rotatably installed on the mounting block 714 through a bearing, which limits the worm 709 while not affecting the rotation of the worm 709, the right side of the mounting block 714 is fixedly connected with the left rear end of the moving block four 715, the front end of the mounting block 714 does not contact the rear end of the worm wheel 708 and the rear end of the rotating rod 707, and the arrangement of the mounting block 714 makes the moving block four 715 move forward and backward, which can drive the worm 709 to move forward and backward through the mounting block 714;

[0050] It should be noted that the length of the arc-shaped convex plate 723 can only push the vibrating plate 704 forward by a distance of half the thickness of the vibrating plate 704, so that the vibrating plate 704 will only protrude a little on the guide plate one 701 and will not be completely removed from the guide plate one 701. When the vibrating plate 704 is reset by the reset spring 703 and abuts against the recessed part of the outer surface of the rotating rod 707, the vibrating plate 704 cannot move backward any more. At this time, the vibrating plate 704 is flush with the upper surface of the guide plate one 701, avoiding the generation of a gap between the vibrating plate 704 and the guide plate one 701, which may cause the medical spring to be stuck in the gap and affect the guiding work.

[0051] The upper end of each of the two track plates 601 is internally provided with a reverse T-shaped movable slot 605, and the two reverse T-shaped movable plates 602 are respectively arranged in the interior of the two reverse T-shaped movable slots 605. The reverse T-shaped movable slots 605 provide moving space for the reverse T-shaped movable plates 602, so that the connecting plates 603 can stably move horizontally on the track plates 601 through the reverse T-shaped movable plates 602. The middle of the interior of the front end reverse T-shaped movable slot 605 is provided with a gear plate 606, the lower end of the spur gear 713 is engaged with the upper end of the gear plate 606, and the lower end of the front end reverse T-shaped movable plate 602 is internally provided with a through slot 607 matched with the gear plate 606. The through slot 607 provides space for the gear plate 606, so that the front end reverse T-shaped movable plate 602 will not collide and damage the gear plate 606 when moving horizontally in the interior of the track plate 601. The front end of the left connecting plate 603 and the left side of the front end reverse T-shaped movable plate 602 are both provided with rotating slots 722, and the upper and lower sides of the spur gear 713 are respectively arranged in the interiors of the two rotating slots 722. The rotating slots 722 provide moving space for the spur gear 713, so that the spur gear 713 can rotate smoothly.

[0052] The interior of the left connecting plate 603 is internally provided with a moving slot one 719, a moving slot two 720 and a moving slot three 721, and the left and right sides of the moving slot two 720 are respectively communicated with the moving slot one 719 and the moving slot three 721.

[0053] Example 2:

[0054] Please refer to Figure 1 - Figure 5As shown, the precision adjusting mechanism 2 comprises a screw rod 201, and the screw rod 201 is rotatably installed on the upper surface of the base 1 through a bearing seat 202, the circumferential surface of the left side of the screw rod 201 is threadedly connected with a moving block 203, the upper end of the moving block 203 is provided with a moving table 204, the lower surfaces of the front and rear ends of the moving table 204 are both provided with sliding blocks 205, the lower ends of the sliding blocks 205 at the front and rear ends are both slidably connected with sliding rails 206, and the two sliding rails 206 are both arranged on the upper surface of the base 1. The sliding blocks 205 and the sliding rails 206 can limit and support the moving table 204, so that when the screw rod 201 rotates, the moving table 204 can slightly move in the left-right direction, the upper end of the moving table 204 is rotatably installed with a screw rod 208 through a bearing seat 207, the circumferential surface of the rear side of the screw rod 208 is threadedly connected with a moving block 209, the upper end of the moving block 209 is provided with a moving table 210, the lower surfaces of the left and right sides of the moving table 210 are both provided with sliding blocks 211, the lower ends of the sliding blocks 211 on the left and right sides are both slidably connected with sliding rails 212, and the two groups of sliding rails 212 are arranged at the left and right ends of the upper surface of the moving table 204. Four vertical columns 5 are arranged at the four corners of the upper surface of the moving table 210. The sliding blocks 211 and the sliding rails 212 can limit and support the moving table 210, so that when the screw rod 208 rotates, the moving table 210 can slightly move in the front-rear direction, thereby more accurately adjusting the position of the spring clamping mechanism 604 and improving the precision during medical spring cutting.

[0055] A wire cutting mechanism 3 is arranged on the left side of the upper surface of the base 1, and the wire cutting mechanism 3 comprises two groups of servo motors 301, and the servo motors 301 are arranged on the upper surface of the base 1 through motor seats. The power output ends of the two groups of servo motors 301 are both transmissionally connected with silk cylinders 302, the circumferential surfaces of the two groups of silk cylinders 302 are both wound with cutting wires 303, a vertical mounting seat 304 is arranged on the right side of the servo motor 301, and the vertical mounting seat 304 is provided with two groups of vertical mounting seats 304. The upper and lower sides of the surfaces of the two groups of vertical mounting seats 304 are respectively provided with tensioning plates 306 and guide plates 305. The upper and lower ends of the right side of the cutting wire 303 are arranged in the interiors of the tensioning plates 306 and the guide plates 305 through tensioning wheels 308 and guide wheels 307. Through the arrangement of the two groups of cutting wires 303, the front and rear ends of the medical spring can be cut at the same time, so that the medical spring is cut into three segments with the same or different lengths, the rapid cutting work is realized, and the cutting efficiency is improved.

[0056] It should be noted that the two collecting boxes 8 are not in contact with the lower surface of the connecting plate 603, and the front-end collecting box 8 is a telescopic box, so that when the guide plate one 701 moves forward and backward, the front-end collecting box 8 can be telescoped, which does not affect the movement of the guide plate one 701 and the collecting work of the collecting box 8, and at the same time, the collecting box 8 is always located on one side of the guide plate 305, and does not collide with the guide plate 305 when the connecting plate 603 moves horizontally left and right. Because the rear wire cutting mechanism 3 is fixed, the distance between the rear collecting box 8 and the guide plate 305 is unchanged, so it is not necessary to move and telescope the rear collecting box 8 and the guide plate two 702. At the same time, the rear end is relatively short, so the guide distance of the guide plate two 702 is relatively short, and the spring does not appear on the surface of the guide plate two 702. Therefore, it is not necessary to set a vibration mechanism in the guide plate two 702, so that the cut medical spring can be smoothly guided into the interior of the rear collecting box 8.

[0057] The lower end of the rear vertical mounting seat 304 is fixedly installed on the upper surface of the base 1, and the lower end of the front vertical mounting seat 304 is provided with a position adjusting mechanism 4. The position adjusting mechanism 4 comprises a horizontal mounting seat 401, which is arranged on the upper surface of the base 1. A screw rod three 403 is rotatably installed in the horizontal mounting seat 401 through a bearing seat three 402. A moving block three 404 is threadedly connected to the circumferential surface of the rear side of the screw rod three 403. The upper end of the moving block three 404 is fixedly connected to the lower surface of the front vertical mounting seat 304. The front vertical mounting seat 304 is slidably installed on the horizontal mounting seat 401. By rotating the screw rod three 403, the moving block three 404 and the front vertical mounting seat 304 can be slightly moved in the front-rear direction, so as to adjust the position of the front cutting wire 303, so that the length of the front section and the middle section of the medical spring can be changed, and the application range is wider. The upper end of each vertical mounting seat 304 is rotatably installed with a screw rod four 405. The circumferential surface of each screw rod four 405 is threadedly connected with a lifting block 406. One side of each lifting block 406 is connected with the side wall of each tensioning plate 306. By rotating the screw rod four 405, the lifting block 406 drives the tensioning plate 306 to move vertically, so as to make the tensioning wheel 308 move up and down, adjust the tightness of the cutting wire 303, and make the cutting wire 303 always in the best cutting state.

[0058] The lower part of the right side wall of the front end vertical mounting base 304 is provided with an L-shaped moving plate 718, the rear side of the right end of the L-shaped moving plate 718 is provided with an inverted U-shaped push block 717, the inside of the inverted U-shaped push block 717 abuts against a push rod 716, the left side of the lower end of the push rod 716 is fixedly connected with the right side wall of the left side moving block four 715, the arrangement of the inverted U-shaped push block 717 can not affect the left-right horizontal movement of the push rod 716, and the arrangement of the L-shaped moving plate 718 can drive the push rod 716 to move horizontally forward and backward synchronously when the front end vertical mounting base 304 moves horizontally forward and backward, so that the push rod 716 drives the front end guide plate one 701 to move horizontally forward and backward synchronously and the front end collecting box 8 to expand and contract synchronously, and the rear side of the guide plate one 701 is always in front of the front end cutting line 303 and does not contact the cutting line 303, and the rear side of the collecting box 8 does not contact the front end of the guide plate 305.

[0059] In use, first, the spring clamping mechanism 604 is opened, then the medical spring is pushed into the inside of the spring clamping mechanism 604 from the rear side of the spring clamping mechanism 604, and then is clamped and fixed through the spring clamping mechanism 604, then the connecting plate 603 is pushed horizontally to the left (the pushing mode can be manual pushing or pushing through a push-pull mechanism arranged on the right side of the connecting plate 603), and the servo motor 301 works, in the process that the connecting plate 603 drives the spring clamping mechanism 604 and the medical spring to move to the left side, the two groups of cutting lines 303 cut the medical spring, and the front and rear ends of the medical spring are cut off and fall on the corresponding guide plate one 701 and guide plate two 702, and the medical spring cut off at the front end is vibrated by the vibration plate 704 in the guide plate one 701 and is guided into the inside of the front end collecting box 8, and the medical spring at the rear end is guided by the guide plate two 702 and is collected into the inside of the rear end collecting box 8;

[0060] In the process that the connecting plate 603 moves, the straight gear 713 meshes with the toothed plate 606, so that the straight gear 713 rotates, and then drives the rotating shaft two 712, the cross rotating rod 710 and the worm 709 to rotate, the rotation of the worm 709 drives the worm wheel 708, the rotating rod 707 and the circular hollow plate 706 to rotate, in the process that the circular hollow plate 706 rotates, when the arc-shaped convex plate 723 on the surface of the circular hollow plate 706 rotates to contact the abutting plate 705, the arc-shaped convex plate 723 can push the abutting plate 705 and the vibration plate 704 to move forward, when the arc-shaped convex plate 723 does not contact the abutting plate 705, the vibration plate 704 moves backward to reset under the action of the reset spring 703, the vibration plate 704 realizes reciprocating vibration, so that the medical spring falling on the surface of the vibration plate 704 is vibrated downward, and the medical spring is prevented from staying on the surface of the guide plate one 701 and affecting work;

[0061] After all the medical springs have been cut, the spring clamping mechanism 604 is activated, so that the next set of medical springs is pushed into the spring clamping mechanism 604 from the rear side, pushing out the medical springs that were previously located inside the spring clamping mechanism 604 and letting them fall onto the guide plate 701. Then they fall into the front collection box 8 and are collected, and then the wire cutting of the subsequent medical springs continues.

[0062] Example 3:

[0063] like Figure 13 As shown, a control cabinet is also installed on one side of the base 1. The control cabinet contains an intelligent monitoring module, which is used to collect real-time operating information of the servo motor 301. This operating information includes the operating current of the servo motor 301, the spindle temperature of the servo motor 301, and the spindle torque. The operating information is analyzed specifically as follows:

[0064] Within a certain time range, the operating current, spindle temperature, and spindle torque of the servo motor 301 are dediminished and their values ​​are taken. Then, the corresponding values ​​are summarized to obtain the set of operating current, set of spindle temperature, and set of spindle torque.

[0065] Obtaining the preset current IN, preset temperature WN, and preset torque TN of the servo motor 301 constitutes the preset information of the servo motor 301. The preset current IN, preset temperature WN, and preset torque TN are 70% to 100% of the rated current, temperature, and torque, respectively, and can be customized by technicians according to actual use.

[0066] Substituting the values ​​of the operating current set, spindle temperature set, and spindle torque set into the SSIM exponential model, the SSIM operating exponent SSIM(x, N) of the servo motor 301 is output; where the SSIM exponential model is:

[0067] SSIM(x, N) = I(x, N) * W(x, N) * T(x, N); where I(x, N) is the current deviation and W(x, N) is the temperature deviation; I(x, N) = (2 * IPx * IN + 1) / (IPx 2 +IN 2 +1), IPx is the mean of all operating currents in the operating current set; W(x, N) = (2*σxN+1) / (σx 2 +WN 2+1), and sigma x is the standard deviation of all spindle temperatures in the spindle temperature set, and sigma xN is the absolute value of the difference between the average of all spindle temperatures in the spindle temperature set and the preset temperature; T(x, N) = (mu xN+1) / (mu x*TN+1), wherein mu x is the standard deviation of all spindle torques in the spindle torque set, and mu xN is the absolute value of the difference between the average of all spindle torques in the spindle torque set and the preset torque; the value range of SSIM(x, N) is between 0 and 1, and the closer the value is to 1, the closer the running information is to the preset information; otherwise, the farther the value is from the preset information;

[0068] If the SSIM running index is less than or equal to the threshold value one and greater than the threshold value two, a running deviation instruction is generated and displayed on the display screen on the control cabinet, and the servo motor 301 is controlled to stop running for 20 minutes; if the SSIM running index is less than the threshold value two, a shutdown instruction is generated, the servo motor 301 is controlled to stop running, and the shutdown instruction is sent to the intelligent terminal of the corresponding technical personnel for display, and the alarm on the control cabinet is controlled to alarm.

[0069] It should be noted that 0 < threshold value two < threshold value one < 1; the size is set by the technical personnel.

[0070] The current, temperature and torque of the servo motor 301 are jointly analyzed, and the nonlinear fusion evaluation is realized through the SSIM index model, so that the health running of the servo motor 301 is monitored in real time, and the problems of the servo motor 301 are avoided, so that the precision of medical spring wire cutting is reduced.
