Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic knife processing, in particular to an ultrasonic knife head forming device. Background Art

[0002] The main working mechanism of the ultrasonic scalpel is that the host outputs an electrical signal, and the transducer uses the electrostrictive effect or magnetostrictive effect to convert ultrasonic electrical energy into mechanical energy to generate high-frequency vibration. Through the amplification and coupling of the amplitude transformer, the blade is driven to work and transmit energy to local tissues of the human body, thereby achieving the purpose of surgical treatment. The processing of the ultrasonic scalpel blade often requires the use of a mold forming device.

[0003] The prior art discloses patent application number "CN202323369903.0", which is an ultrasonic tool processing and forming device with improved precision, including: a processing table, a material storage box, a tool holder and an ultrasonic tool.

[0029] Two symmetrically arranged U-shaped plates 11 are installed on the upper side of the top plate 8. Both ends of the two U-shaped plates 11 are slidably connected with a block slide rod 12 for fixing the upper mold base 10. A first spring 13 is fixedly connected between the four block slide rods 12 and the U-shaped plates 11. Both ends of the top plate 8 and the upper mold base 10 are clamped with a U-shaped clamping seat 16. The upper side of the top plate 8 is threadedly connected with a first bolt 17 for fixing the U-shaped clamping seat 16.

[0030] Two symmetrically arranged horizontal plates 3 are installed on the upper side of the base plate 1. The inner sides of the two horizontal plates 3 are connected to two round rods 4. The outer surfaces of the two round rods 4 are slidably connected to two symmetrically arranged displacement plates 24. The inner sides of the two displacement plates 24 are connected to positioning seats 25 for fixing the lower mold base 2. Through the installation and use of the displacement plates 24 and the positioning seats 25, the two displacement plates 24 can drive the positioning seats 25 to move smoothly on the two round rods 4, so as to be used for installing or disassembling the lower mold base 2, which is easy to use.

[0031] A reinforcement plate 26 is fixedly connected to the inner side surface of the base plate 1, and an L-shaped fixed plate 27 is installed on the lower side of the base plate 1. A rotating shaft seat 28 is rotatably connected between the reinforcement plate 26 and the L-shaped fixed plate 27. U-shaped seats 29 are respectively installed on the lower sides of the two displacement plates 24. A rotating plate 30 is rotatably installed inside the two U-shaped seats 29 and the rotating shaft seat 28. The lower side of the rotating shaft seat 28 passes through the L-shaped fixed plate 27 and extends to the lower side of the L-shaped fixed plate 27. A servo motor 31 is installed on the lower side of the rotating shaft seat 28 through the motor mounting plate.

[0032] Both ends of the top plate 8 are connected with T-shaped sliders 23, and four vertical concave plates 21 are respectively clamped on the upper side of the lower die base 2. Both ends of the lower die base 2 are threadedly connected with two third bolts 22 for fixing the vertical concave plates 21. The T-shaped slider 23 is located inside the vertical concave plates 21, and one side of the T-shaped slider 23 is slidably connected to the inside of the vertical concave plates 21. By installing and using the vertical concave plates 21 and the T-shaped slider 23, the T-shaped slider 23 is moved up and down at the vertical concave plates 21, so that the entire upper die base 10 can stably perform molding work.

[0033] The upper side of the base plate 1 is slidably connected to four L-shaped stoppers 5 for fixing the lower die base 2. Four side plates 19 are installed on the upper side of the base plate 1. The insides of the four side plates 19 are slidably clamped with L-shaped plug plates 20 for fixing the L-shaped stoppers 5.

One side of the two connecting plates 14 is threadedly connected with a second bolt 18. Through the setting of the second bolt 18, as long as the two connecting plates 14 are pressed at the same time, the two connecting plates 14 are moved toward each other, which is used to make the block slide 12 move away from the positioning rod 9 so as to release the limit on the upper mold base 10. At the same time, the second bolt 18 is rotated to the other connecting plate 14 to limit and accommodate the two elastic block slides 12. One side of the second bolt 18 passes through the connecting plate 14 and extends to the other side of the connecting plate 14.

[0035] A through positioning hole 32 is formed inside each of the four positioning rods 9 . The positioning hole 32 matches the block slide rod 12 . One side of the block slide rod 12 is engaged with the inside of the positioning rod 9 through the positioning hole 32 .

[0038] The two U-shaped clamping seats 16 are clamped to the two ends of the top plate 8 and the upper mold base 10 to fix the upper mold base 10, and then the two first bolts 17 are rotated respectively so that the first bolts 17 can squeeze and fix the U-shaped clamping seats 16 to ensure the stability of the upper mold base 10 during installation. Then, the second bolts 18 of the two connecting plates 14 are rotated in sequence to release the limit of the two sets of connecting plates 14. The elastic force of the first spring 13 can allow the four clamping block slides 12 to be changed from the limited state to the released state. At this time, the four clamping block slides 12 can be clamped to the positioning holes 32 of the positioning rods 9 to further fix the upper mold base 10. In this way, the new upper mold base 10 can be flexibly and conveniently replaced by plugging in, without the need to use cumbersome bolts to fix the upper mold, which saves time and effort in operation, thereby improving the processing efficiency of the ultrasonic knife head forming device;

[0039] The lower die base 2 is placed on the bottom plate 1, and then the four L-shaped stoppers 5 are moved upward respectively, and then the L-shaped plug plate 20 is pushed to clamp and fix the L-shaped stoppers 5. At this time, the four L-shaped stoppers 5 can be used to locate the position of the lower die base 2, and then the output shaft of the servo motor 31 drives the rotating shaft seat 28 to rotate to drive the two rotating plates 30 to rotate and adjust at the same time, so that the two displacement plates 24 move toward each other on the two round rods 4, and the positioning seats 25 at the two displacement plates 24 are clamped to the two ends of the lower die base 2 to clamp and fix the lower die base 2 to ensure the stability of the entire forming device. Then the hydraulic cylinder 7 drives the upper die base 10 to move downward, allowing the upper die base 10 to enter the interior of the lower die base 2 so that the ultrasonic knife head can be pressed and formed. At the same time, the four T-shaped sliders 23 can be used to allow the upper die base 10 to move up and down smoothly at the four vertical concave plates 21, so that the ultrasonic knife head forming work can proceed smoothly.
