Description
Technical Field
[0001] The invention relates to the technical field of drill bit processing, and in particular to a handheld metal raw material shearing device for drill bit processing. Background Art
[0002] Drill bits are usually made of metal materials, such as steel or carbon steel, and these materials need to be precisely cut and processed during the manufacturing process. Handheld metal raw material shearing equipment can be used to horizontally shear metal materials before drill bit processing. Through handheld shearing equipment, drill bit manufacturers can effectively handle and process various materials to ensure the production of drill bit products that meet high quality standards.
[0003] Existing handheld metal raw material (here refers to plate-shaped metal raw materials, which are usually made of high-strength alloy steel and have excellent mechanical properties and wear resistance. This allows the drill made of plate-shaped metal raw materials to remain stable and durable under high-load and high-speed rotation conditions. At the same time, the plate-shaped metal raw materials can be processed into various complex drill bit shapes through cutting processes) shearing equipment for drill bit processing. When shearing raw materials, because the shearing equipment usually drives the shearing head or blade for shearing through an electric or pneumatic drive system, these power systems will vibrate during operation, especially when running at high speed or shearing harder materials. The vibrations will be transmitted to the operator's hands and arms, causing the operator to need additional muscle strength to offset these vibrations to keep the equipment stable. This continuous resistance will cause muscle fatigue, which in turn leads to operational instability, causing the operator to accidentally injure himself or others during the shearing process;
[0004] At the same time, the operator's muscle fatigue will also lead to the inability to accurately cut the metal raw materials in a horizontal straight line, resulting in uneven or uneven cutting ports, inconsistent specifications of the cut raw materials, and the final drill bit size cannot meet the design requirements, increasing the difficulty and cost of subsequent processing.

DETAILED DESCRIPTION
[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the 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.
[0039] The present invention will be further described below in conjunction with the embodiments.
[0040] Example: Refer to Figures 1 to 14 , a handheld metal raw material shearing device for drill bit processing, comprising:
[0041] A handle 1, wherein the shaft of the handle 1 is provided with at least two grip grooves, and two switches with different functions are arranged at the grip grooves;
[0042] The positioning shearing mechanism 2 includes a fixing plate 21 fixedly connected to the top of the handle 1, a shearing clamp block 22 and a fixing clamp block 23 are arranged on one side of the fixing plate 21, a compression box 24 and a scale 25 are arranged in parallel at the center of the fixing plate 21, and a lifter 241 is arranged in the compression box 24, and two track detection components 28 are symmetrically arranged on the opposite surfaces of the shearing clamp block 22 and the fixing clamp block 23;
[0043] The vibration compensation mechanism 3 includes two shock absorbing boxes 31 fixedly connected to the side of the fixed plate 21 facing the grip groove and symmetrical to the compression box 24. A shock-absorbing box 34 and two shock-absorbing members 33 symmetrical to the shock-absorbing box 34 are arranged inside the shock-absorbing box 31. A pair of weight rods 35 are arranged in the shock-absorbing box 34. The weight rods 35 are located on the fixed clamp block 23 and are vertically fixed with a fixed rod 351 running through the rod body.
[0044] The vibration conversion mechanism 4 includes a plurality of support components 41 arranged in a linear array on the inner walls of both sides of the shock-absorbing box 34, wherein the support components 41 are respectively provided with a plurality of first connecting columns 42 and a plurality of second connecting columns 43 alternately arranged, and the first connecting columns 42 and the second connecting columns 43 are respectively provided with elastic rods 44 and interconnecting rods 432.
[0045] When it is necessary to shear the metal raw material, the positioning shearing mechanism 2 uses the shearing clamp 22 and the fixed clamp 23 to clamp and fix the metal raw material. Since the metal raw material is located between the shearing clamp 22 and the fixed clamp 23, a gap will be formed between the shearing clamp 22 and the fixed clamp 23. The scale 25 measures the rise of the shearing clamp 22 to measure the length of the gap between the shearing clamp 22 and the fixed clamp 23, and then the thickness of the metal raw material is obtained. At the same time, the trajectory detection component 28 can calculate the trajectory of the positioning shearing mechanism 2 for shearing the metal raw material, so as to determine whether the metal raw material has a position deviation during shearing, and through the vibration compensation mechanism 3, the vibration force generated by the positioning shearing mechanism 2 when shearing the metal raw material can be absorbed and concentrated, so as to transmit the vibration force to the vibration conversion mechanism 4 in a direction, and the vibration conversion mechanism 4 can offset and convert the vibration force transmitted by the vibration compensation mechanism 3, so as to avoid the vibration force being directly transmitted to the operator's hands and arms, thereby causing the operator to become tired.
[0046] Reference Figures 1 to 5The shearing clamp block 22 is slidably connected to the bottom of the fixed plate 21 facing the grip groove. The side of the shearing clamp block 22 facing the fixed plate 21 is symmetrically fixedly connected with two groups of sliders 221 with the compression box 24 as the center. Each group of sliders 221 has at least two. The middle part of the shearing clamp block 22 is rotatably connected to the saw blade 26. The bottom of the shearing clamp block 22 is fixedly connected to a driver 27 for driving the saw blade 26, and the driver 27 is electrically connected to one of the switches. The fixed clamp block 23 is fixedly connected to the top of the fixed plate 21 facing the grip groove. The middle of the top of the fixed clamp block 23 is fixedly connected to the top of the fixed plate 21. The center position fixing cover is provided with a protective cover 231, and the saw blade 26 corresponds to the position of the protective cover 231, a reader 232 is fixedly connected to the top of the fixed clamp block 23 and at the corresponding position of the scale 25, the reader 232 is electrically connected to the driver 27, two elastic seats 234 are symmetrically fixedly connected to the top of the fixed clamp block 23 about the weight rod 35, the two elastic seats 234 are fixedly connected to both sides of the outer peripheral surface of the fixed rod 351, and a frequency detector 233 is fixedly connected to the top of the fixed clamp block 23 and at the corresponding position of any weight rod 35.
[0047] The fixed clamp 23 can use the reader 232 on its top to read the scale 25, thereby obtaining the thickness of the metal material clamped between the shear clamp 22 and the fixed clamp 23 at this time, and transmit this result to the dynamic driver 27, so that the driver 27 outputs different powers to the saw blade 26 according to the thickness of the metal material, and the weight rod 35 can consume the energy converted into vibration force in the vibration conversion mechanism 4, so as to further offset the vibration force.
[0048] Reference Figures 2 to 5 The compression box 24 is fixedly arranged on the shear clamp 22 and the fixed clamp 23, the lifter 241 is fixedly connected to the inner middle part of the compression box 24, and another switch is electrically connected to the lifter 241, the ruler 25 contacts the middle part of the compression box 24 away from the fixed plate 21, the bottom of the ruler 25 is fixedly connected to the shear clamp 22, and the top of the ruler 25 passes through the fixed clamp 23 and is slidably connected to the fixed clamp 23.
[0049] The switch at the grip groove can be used to control the lifting of the lifter 241, thereby driving the distance between the shearing clamp 22 and the fixed clamp 23, so that the shearing clamp 22 and the fixed clamp 23 can clamp and measure metal raw materials of different thicknesses, thereby controlling the output power of the driver 27 to the saw blade 26, and realizing the precise shearing of the metal raw material by the saw blade 26.
[0050] Reference Figure 2 , Figure 6 to Figure 7The track detection component 28 includes two connecting blocks 281 that are slidably connected to the opposite surfaces of the shear clamp 22 and the fixed clamp 23. The two connecting blocks 281 are horizontally and equidistantly fixedly connected with a guide wheel 282, a first magnetic detection wheel 284 and a second magnetic detection wheel 286 on one side away from the shear clamp 22 and the fixed clamp 23. The guide wheel 282, the first magnetic detection wheel 284 and the second magnetic detection wheel 286 form a magnetization zone and a demagnetization zone in the connecting block 281 with the guide wheel 282 as the starting point along the length direction of the connecting block 281. A plurality of magnetization wheels 283 are rotatably connected in a horizontal array in the magnetization zone, and a plurality of demagnetization wheels 285 are rotatably connected in a horizontal array in the demagnetization zone. A demagnetization coil 287 is fixedly connected to the interior of each demagnetization wheel 285.
[0051] The trajectory detection component 28 can locate and detect the trajectory of the metal raw material being sheared, so as to determine whether there is a position deviation when the positioning shearing mechanism 2 performs horizontal shearing on the metal raw material. The attached magnetic wheel 283 is used to magnetize the metal raw material passing through here, and the first magnetic detection wheel 284 can detect whether the magnetized trajectory is in the same straight line position. The demagnetization wheel 285 can demagnetize the magnetized part of the metal raw material, and the second magnetic detection wheel 286 is used to detect whether the position of the metal raw material after demagnetization is magnetic, so as to determine whether there is a position deviation when the positioning shearing mechanism 2 performs shearing on the metal raw material.
[0052] Reference Figures 8 to 11 The side of the shock-absorbing box 31 away from the fixed plate 21 is fixedly connected to the track 32 slidably connected to each slider 221, the shock-resistant box 34 is fixedly connected to the inner middle part of the shock-absorbing box 31, the shock-absorbing member 33 is made of multiple shock-absorbing sheets, the side of the shock-absorbing member 33 away from the shock-resistant box 34 is fixedly connected to the inner wall of the shock-absorbing box 31, a pair of weight rods 35 are air-tightly slidably connected to the top of the shock-resistant box 34, the weight rods 35 pass through the fixed clamping block 23 and are slidably connected thereto, at least three groups of collecting sheets 36 are fixedly connected to the inner walls of both sides of the shock-resistant box 34 in a linear array, the number of collecting sheets 36 in each group is at least two pairs, and the inclination directions of each pair of collecting sheets 36 are opposite.
[0053] The shock absorbing box 31 can realize the free up and down movement of the shear clamp 22 by using the track 32 and the slider 221. At the same time, the vibration generated by the shear clamp 22 when shearing the metal raw material will also be transmitted to the shock absorbing box 31. The shock absorbing box 31 can further transmit the vibration wave to the shock-resistant box 34 by using the internal shock absorbing member 33. The shock absorbing member 33 can gradually offset and disperse the vibration wave when transmitting it, thereby reducing the vibration wave energy transmitted from the shock absorbing member 33 to the shock-resistant box 34, thereby reducing the pressure of the vibration conversion mechanism 4 in the shock-resistant box 34 on the vibration wave processing.
[0054] Reference Figure 12 to Figure 13The support assembly 41 and the collecting piece 36 are staggeredly arranged on the same two side inner walls of the shock-absorbing box 34. The support assembly 41 includes two diamond-shaped fixing seats 411 fixedly connected to the inner walls on both sides of the shock-absorbing box 34. The opposite surfaces of the two diamond-shaped fixing seats 411 are fixedly connected with a connecting rod 412. A plurality of first connecting columns 42 are fixedly connected to the rod body of the connecting rod 412 in a horizontal array. A break is formed between every two adjacent first connecting columns 42. Two second springs 431 are symmetrically fixedly connected at the break. The second connecting column 43 is fixedly connected to the opposite end of the two second springs 431.
[0055] The vibration conversion mechanism 4 is fixed in the shock-absorbing box 34 by means of the support assembly 41, and the support assembly 41 utilizes the elastic movement of the first connecting column 42 and the second connecting column 43 to offset and consume the vibration force transmitted to the inside of the shock-absorbing box 34, thereby preventing the vibration force from being transmitted to the operator's arm through the handle 1 and causing muscle fatigue in the operator.
[0056] Reference Figure 13 to Figure 14 The upper and lower ends of the first connecting column 42 are symmetrically fixedly connected with the first spring 421, and the end of the first spring 421 away from the first connecting column 42 is fixedly connected with a circular fixing seat 422, and the end of the circular fixing seat 422 away from the first spring 421 is fixedly connected to the inner wall of the shock-absorbing box 34, and the interconnection rod 432 is fixedly connected to the outer peripheral surface of the second connecting column 43, and the interconnection rod 432 is fixedly connected to the outer peripheral surface of the second connecting column 43. Two adjacent second connecting columns 43 form a placement area through the interconnection rod 432, and the elastic rod 44 is fixedly connected to the outer peripheral surface of the first connecting column 42 at the center position of the connecting rod 412. The outer peripheral surface of the elastic rod 44 surrounds multiple groups of wave-focusing covers 45 in the array, and each group of wave-focusing covers 45 has at least one pair, and the wave-focusing covers 45 are located in the placement area.
[0057] The wave focusing cup 45 can further collect and buffer the vibration force, because the elastic rod 44 used to fix the wave focusing cup 45 is made of elastic material. When the wave focusing cup 45 collects the vibration force, the vibration force is transmitted to the elastic rod 44, and the elastic rod 44 uses its deformation to offset the energy of the vibration force acting on the wave focusing cup 45.
[0058] The operating principle of this embodiment is as follows:
[0059] Step 1: Hold the handle 1 with your hand, and then horizontally correspond the raw material to be sheared with the space formed by the shearing clamp block 22 and the fixed clamp block 23 in the positioning shear mechanism 2, so that the raw material to be sheared is placed between the shearing clamp block 22 and the fixed clamp block 23, and then press the switch in the handle 1 for controlling the lifter 241 (the switch here is a three-position switch with three modes of up, down and off, which respectively control the lifting state of the lifter 241), so that the shearing clamp block 22 starts to rise toward the fixed clamp block 23 through the lifter 241, so that the shearing clamp block 22 and the fixed clamp block 23 form a clamping state for the raw material, and this clamping state is not completely clamped. When the shearing clamp block 22 and the fixed clamp block 23 form a clamping state for the raw material, since the raw material is in contact with the track detection component 28, the shearing The force formed by the clamping of the cutting clamp block 22 and the fixed clamp block 23 will first act on the track detection component 28, causing the track detection component 28 to start to slide down (the maximum extent of the slide of the track detection component 28 is to be level with the cutting clamp block 22, and when the clamping force of the cutting clamp block 22 and the fixed clamp block 23 disappears, the connecting block 281 will return to its initial state), and as the connecting block 281 slides down, the rise of the cutting clamp block 22 will form a certain resistance (this indicates that the raw material is in contact with the track detection component 28), causing the lifter 241 (the lifter 241 contains a pressure sensor) to stop the lifting operation of the cutting clamp block 22, so that the cutting clamp block 22 and the fixed clamp block 23 form a relatively soft clamping state for the raw material (because the track detection component 28 forms a barrier to it).
[0060] Among them, when the lifter 241 drives the shear clamp 22 to rise, the ruler 25 also begins to rise with the rise of the lifter 241, so that the ruler 25 continues to move above the fixed clamp 23, and when the lifter 241 stops lifting the shear clamp 22, it means that the shear clamp 22 and the fixed clamp 23 complete the clamping of the raw material, so the reader 232 will read the current length of the ruler 25 fixed clamp 23 moving above (Note: the thickness of the raw material obtained by the reader 232 will subtract the thickness of the track detection component 28, because the thickness value of the track detection component 28 is a fixed value), thereby obtaining the thickness of the raw material at this time, and the thickness data of the raw material The data is transmitted to the driver 27 (the driver 27 has: a motor, a transmission mechanism and a controller, and the controller is used to control the current input to the motor, and the data transmitted by the reader 232 directly acts on the controller), and the driver 27 can output corresponding power to the saw blade 26 according to the thickness of the raw material transmitted by the reader 232. By adjusting the power output of the driver 27 to the saw blade 26 according to the thickness of the raw material, it can be ensured that the shearing speed of the saw blade 26 corresponds to the thickness of the raw material, thereby improving the quality and accuracy of the incision when the saw blade 26 shears the raw material, because too high or too low a rotation speed can cause uneven incisions, burrs or material damage, affecting the final quality of the product. By adjusting the rotation speed according to the thickness, these problems can be avoided to the greatest extent. At the same time, the shearing speed of the saw blade 26 corresponds to the thickness of the raw material to ensure that the cutting process is more stable and smooth. If the rotation speed is too high or too low, it will cause unstable vibrations when the saw blade 26 contacts the raw material. This vibration will affect the cutting accuracy and surface quality of the raw material, and will also additionally enhance the vibration of the equipment (the equipment refers to the handheld shearing equipment, and the handheld shearing equipment and the equipment have the same meaning hereinafter and can be used interchangeably). By adjusting the rotation speed of the saw blade 26 according to the thickness of the raw material, this unnecessary vibration can be reduced or eliminated, thereby reducing the fatigue of the operator caused by vibration.
[0061] When the saw blade 26 shears the raw material, the operator controls the device to move in the raw material through the handle 1, thereby shearing the raw material. At this time, since the track detection component 28 is in contact with the raw material, the device will also drive the connecting block 281 during the movement of the raw material (at this time, the track detection component 28 is clamped by the shearing clamp 22 and the fixed clamp 23, and is flush with the shearing clamp 22). At this time, the raw material will slide horizontally in the track detection components 28 symmetrical on both sides, and when the raw material slides horizontally, it will sequentially contact the guide wheel 282, the magnetic wheel 283, the first magnetic wheel 281 and the track detection component 28. The magnetic detection wheel 284, the demagnetizing wheel 285 are in contact with the second magnetic detection wheel 286 (the guide wheel 282, the magnetic wheel 283, the first magnetic detection wheel 284, the demagnetizing wheel 285 and the second magnetic detection wheel 286 are horizontally arranged in the connecting block 281, so when the raw material is detected by the track detection component 28, it is considered to be horizontally sheared), so as to realize the positioning and detection of the metal raw material track to be sheared, so as to judge whether there is a position deviation when the positioning shearing mechanism 2 performs horizontal shearing on the metal raw material. The magnetic wheel 283 is used to magnetize the metal raw material passing through here, and the guide wheel 282 can The raw material is positioned and guided (the guide wheel 282 will record the position in the raw material at this time), so as to determine the initial position of the horizontal cutting of the raw material, and the magnetic wheel 283 is composed of a strong magnet, so when the raw material passes through the magnetic wheel 283, the raw material in the area where the magnetic wheel 283 passes will be magnetized, and then, the magnetized area of the raw material will be contacted and detected by the first magnetic detection wheel 284, so as to determine whether the magnetized area of the raw material at this time is horizontally the same as the cutting position determined by the initial position of the guide wheel 282, so as to determine whether the saw blade 26 cuts the raw material horizontally (straight horizontal cutting), if not horizontally, the track detection component 28 will send an abnormal signal to the driver 27 (the signal of the horizontal track detection component 28 is also transmitted to the controller), and reduce the rotation speed of the saw blade 26, and issue an early warning to remind the operator to make adjustments. Then, the raw material will be demagnetized by the demagnetizing wheel 285, so as to remove the magnetic force of the magnetized area of the raw material. The reason why the demagnetizing wheel 285 can demagnetize the magnetized area of the raw material is that the demagnetizing coil 287 inside the demagnetizing wheel 285 (the demagnetizing coil 287 generates a magnetic field in a specific direction by energizing. During demagnetization, the demagnetizing coil 287 will generate a magnetic field in the opposite direction to the original magnetic field of the object to be demagnetized.The effect of this reverse magnetic field can completely destroy the magnetic particles (such as magnetic moment) in the original object, thereby achieving demagnetization of the magnetized area of the raw material). After the demagnetization of the magnetized area of the raw material is completed, the raw material passes through the second magnetic detection wheel 286 for magnetic detection. Because it detects whether there is still magnetic force, if there is magnetic force, the operation at the first magnetic detection wheel 284 will be repeated. Only when the raw material satisfies the detection of the first magnetic detection wheel 284 and the second magnetic detection wheel 286 in the trajectory detection component 28 at the same time, the raw material is considered to be horizontally sheared (the size and specifications of the raw material formed by horizontally shearing are consistent, which can ensure that the size and specifications of the drill bit formed by horizontally shearing the raw material in the later stage meet the design requirements). When one of the conditions is not met, an alarm will be issued (reducing the rotation speed of the saw blade 26), and if both conditions are not met, the rotation of the saw blade 26 will be stopped, because it is considered that the equipment has left the cutting area of the raw material at this time, and the stopping of the saw blade 26 can significantly reduce the risk of accidental injury. During operation, if there is no protection mechanism to stop the rotation of the saw blade 26 in time, the staff may accidentally touch the sharp saw blade 26 when adjusting or moving the raw material, causing serious injury.
[0062] Step 2: When the saw blade 26 in the equipment is cutting the raw material, the equipment usually drives the saw blade 26 to shear through an electric or pneumatic drive system, and these power systems will generate vibrations during operation, and the saw blade 26 will also vibrate when shearing the raw material. At the same time, the vibration force will be transmitted to the operator's hands and arms through the equipment, causing the operator to need additional muscle strength to offset these vibrations to keep the equipment stable. This continuous resistance will cause muscle fatigue, so the shock absorbing box 31 in the vibration offset mechanism 3 can use the track 32 and the slider 221 to realize the free up and down movement of the shear clamp 22, and the slider 221 can absorb the vibration force generated by the equipment, thereby transferring the vibration force to the shock absorbing box 31, and the shock absorbing box 31 can use the internal shock absorbing member 33 to The shock wave is further transmitted to the shock-absorbing box 34, and the shock-absorbing member 33 can gradually offset and disperse the shock wave when transmitting it (the main constituent material of the shock-absorbing member 33 is: viscoelastic polymer. The viscous part of the viscoelastic material causes the internal molecules to move relative to each other when the material is subjected to external force (such as vibration or impact). Internal friction is generated during this movement, converting mechanical energy into heat energy, thereby consuming part of the vibration energy. This energy dissipation mechanism reduces the vibration force transmitted to the other side of the material), thereby reducing the shock wave energy transmitted from the shock-absorbing member 33 to the shock-absorbing box 34, thereby reducing the pressure of the vibration conversion mechanism 4 in the shock-absorbing box 34 on the vibration wave processing, and the remaining part of the vibration will be transmitted to the vibration conversion mechanism 4 in the shock-absorbing box 34 for the final vibration energy offset.
[0063] Among them, a collecting piece 36 is arranged in the shock-resistant box 34 (the opening direction of the collecting piece 36 is outward, and the vibration force is from the outside to the inside at this time), and when the vibration force acts on the collecting piece 36, the symmetrically arranged collecting pieces 36 will generate equal and opposite reaction forces, and these forces offset each other, thereby further offsetting the vibration energy and reducing the vibration force transmitted to the equipment. The shock-resistant box 34 is in an overall sealed state, and gas is stored in the shock-resistant box 34 (the gas pressure range is 1-5 atmospheres), and a weight rod 35 is arranged at the bottom of the shock-resistant box 34, and the weight rod 35 (the gravity of the weight rod 35 is proportional to the atmospheric pressure of the gas stored in the shock-resistant box 34) is elastically supported by the elastic seat 234. When the vibration force acts on the shock-resistant box 34, the vibration force will be converted by the vibration conversion mechanism 4 However, when the vibration conversion mechanism 4 absorbs the vibration force, it will be reflected when a wave propagates to a new medium or hits a new surface of an object. Therefore, part of the vibration force will be reflected by the vibration conversion mechanism 4, and the reflected vibration force will contact the collecting piece 36 again. Since the opening direction of the collecting piece 36 is outward (at this time, the vibration force is from the inside to the outside), the vibration force reflected by the collecting piece 36 will cause the gas stored in the shock-absorbing box 34 to fluctuate. As the gas fluctuations occur, the fluctuation energy will act on the weight rod 35, so that the weight rod 35 begins to rise (the rising weight rod 35 will consume the energy generated by the gas fluctuations), and the weight rod 35 will rise a certain distance under the action of the elastic seat 234. The weight rod 35 returns to the initial position of the shock-resistant box 34, but the gas fluctuation is still going on at this time, and the weight rod 35 rises again, and returns to the initial position of the shock-resistant box 34 under the action of the elastic seat 234, so that the weight rod 35 reciprocates until the gas in the shock-resistant box 34 no longer fluctuates. At the same time, the frequency detector 233 can detect the frequency of the reciprocating motion of the weight rod 35 (because the power of the reciprocating motion of the weight rod 35 comes from: the sum of the vibration force generated by the electric or pneumatic drive system driving the saw blade 26 to shear and the saw blade 26 shearing the raw material. At this time, the frequency of the reciprocating motion of the weight rod 35 has a regularity), so as to obtain whether the saw blade 26 cuts the raw material evenly (because the saw blade 26 reacts inconsistently to the raw material due to uneven cutting, resulting in the saw blade 26 cutting the raw material The vibration frequency generated during material shearing changes, thereby affecting the total vibration force, causing the frequency of the reciprocating motion of the weight rod 35 to be irregular). The raw materials sheared unevenly will be uneven, and the drill bit requires very high precision and consistency. If the raw materials are cut unevenly, it will cause deviations in the size and shape of the drill bit in the later stage, making it unable to meet the design requirements, thereby affecting the performance and service life of the drill bit. Therefore, when the frequency detector 233 detects that the frequency of the reciprocating motion of the weight rod 35 is irregular, an audible alarm will be issued (the larger the frequency error, the stronger the alarm sound), so as to conduct manual intervention to find the cause of the uneven cutting (because there are many reasons for uneven cutting, involving mechanical, physical, operational and other aspects,The system cannot make an accurate judgment).
[0064] Step 3: Most of the vibration force transmitted to the shock-absorbing box 34 will be absorbed and offset by the vibration conversion mechanism 4 (the remaining part will be reflected). After absorbing the vibration force, the vibration conversion mechanism 4 will transmit it to the first connecting column 42 and the second connecting column 43 distributed in the connecting rod 412 through the support component 41. The first connecting column 42 and the second connecting column 43 are both made of ethylene-vinyl acetate copolymer (EVA). Ethylene-vinyl acetate copolymer (EVA) has good elasticity and flexibility, which means that it can deform when impacted and quickly return to its original shape after the impact force is removed. This characteristic allows the EVA material to reduce rebound while absorbing energy, thereby achieving a shock-absorbing effect. In addition, by setting the first spring 421 and the second spring 431 in the first connecting column 42 and the second connecting column 43, the vibration force is further offset;
[0065] The reason why the first spring 421 and the second spring 431 can offset the vibration force is as follows:
[0066] Springs obey Hooke's law, which states that within the elastic limit, the extension or compression of a spring is proportional to the applied force. The formula is:
[0067] [F = -kx]
[0068] Where (F) is the restoring force, (k) is the spring constant (stiffness coefficient), and (x) is the deformation (elongation or compression) of the spring. This linear relationship allows the spring to generate a corresponding reaction force when subjected to an external force, thereby offsetting the effect of the external force.
[0069] The wave focusing cover 45 is arc-shaped, and the curved surface design of the arc-shaped wave focusing cover 45 enables it to reflect and interfere with the vibration wave. When the vibration wave hits the arc-shaped surface, part of the wave energy is reflected back (reflected back to act on the gas stored in the shock-absorbing box 34), while the other part of the wave energy propagates inside the material. Due to multiple reflections and interferences, the energy of the vibration wave is gradually dispersed and dissipated, thereby reducing the vibration energy transmitted to the inside of the structure, thereby absorbing and offsetting the vibration force generated when the equipment is working, reducing the adverse effects of vibration on the hands and arms, and enhancing the operator's accurate control of the shearing equipment.
[0070] The curved surface design of the arc-shaped wave focusing cover 45 enables it to reflect and interfere with the vibration wave. When the vibration wave hits the curved surface, part of the wave energy is reflected back, while the other part of the wave energy propagates inside the material. Due to multiple reflections and interferences, the energy of the vibration wave is gradually dispersed and dissipated, thereby reducing the vibration energy transmitted to the inside of the structure.
