Description

Technical Field

[0001] This utility model relates to the field of spring machine technology, and in particular to a spring machine cutting assembly that is easy to adjust. Background Technology

[0002] Spring machines, also known as coiling spring machines, are mechanical equipment used for spring production. They are divided into compression spring machines, tension spring machines, universal spring machines, disc spring machines, and special-purpose spring machines, etc. Spring machines have multiple components, among which the cutting assembly is an important one. The cutting assembly cuts the springs after they have been made. The cutting assembly is driven by a motor and an electric push rod to move the cutting blade. The cutting blade contacts the spring making disc on the spring machine to cut the spring.

[0003] Chinese Patent CN219274336U discloses a convenient and precise adjustable spring cutting assembly, including a spring plate. A guide seat is fixed to the outer wall of the spring plate. A blade holder slides on one end of the guide seat, and an electric telescopic rod rotates on the top of the blade holder. A motor is mounted on one end of the electric telescopic rod, and the output shaft of the motor is fixedly connected to one end of the electric telescopic rod. A blade holder is provided at the end of the blade holder away from the guide seat. A screw thread passes through a protrusion on one end of the blade holder, and one side of the screw is rotatably connected to a fixed plate. A knob is fixed through the fixed plate on the other side of the screw. A guide rod slides through a second protrusion, and both sides of the second protrusion are fixedly connected to the fixed plate. In use, the blade holder rotates via the screw and moves left and right with the help of the guide rod. The alignment of the indicator and scale indicates whether the blade holder is adjusted to the appropriate position, thus enabling precise adjustment of the blade's position.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing spring cutting assembly cannot adjust the position of the cutting blade according to the size of the spring. Different cutting blades need to be replaced when dealing with springs of different sizes, which affects the cutting effect of the spring. At the same time, after the cutting blade has been used for a long time, its levelness cannot be quickly measured. If the levelness of the cutting blade is not good, it will further affect the cutting effect. Utility Model Content

[0005] The purpose of this invention is to address the problems in the prior art where the position of the cutting blade cannot be adjusted according to the size of the spring and the levelness of the cutting blade cannot be measured before use, and to propose a spring-loaded cutting assembly that is easy to adjust.

[0006] The technical solution of this utility model: A conveniently adjustable spring cutting assembly, including a spring cutting body and a discharge port disposed on the spring cutting body; further comprising:

[0007] The adjustable cutting mechanism is located on the side of the spring machine body and is used to adjust the cutting position according to the size of the spring.

[0008] The upper cutter is mounted on the adjusting cutting mechanism and located above the discharge port. The upper cutter is a moving cutter that moves quickly during the cutting process to cut the spring. The lower cutter is located below the discharge port. Before cutting the spring, the lower cutter moves under the control of the adjusting cutting mechanism to move to the working position according to the size of the spring. Then it stays in the working position to support the bottom of the spring and assist the upper cutter in the cutting work.

[0009] The leveling mechanism is located on the side of the adjusting cutting mechanism and is used to measure the levelness of the upper and lower cutters.

[0010] The measuring rod is rotatably mounted on the leveling mechanism. A marking block is set on the side of the measuring rod, and an infrared emitter is set at the end of the measuring rod. The infrared emitter emits infrared rays to illuminate the upper and lower cutters. When the infrared rays are aligned with the end of the cutter, the measuring rod is moved. If the angle of the measuring rod deviates during the movement, it proves that the levelness of the cutter is inaccurate, and the cutter can be adjusted accordingly.

[0011] Preferably, the adjusting cutting mechanism includes a cutting component and an adjusting component;

[0012] The cutting assembly is located on the side and in the upper part of the spring machine body, and is used to quickly move and cut the spring;

[0013] The adjustment component is located on the side of the spring machine body and in the lower half, and is used to adjust the contact position of the lower cutter according to the size of the spring.

[0014] Preferably, the cutting assembly includes a fixing frame, a cylinder, and a push rod;

[0015] A fixed frame is located on the top of the spring machine body, a cylinder is located inside the fixed frame, and a push rod is located at the output end of the cylinder.

[0018] Preferably, the leveling mechanism includes a second slide rail, a positioning hole, a sliding block, a second threaded rod, and a leveling assembly;

[0019] The second slide rail is located on the third body of the spring machine. The positioning hole is located at the end of the second slide rail. The sliding block is slidably located on the second slide rail. The second threaded rod is threaded on the inner side of the sliding block. The top of the second threaded rod is provided with a rotating rod, which is used to drive the second threaded rod to rotate on the sliding block. The inner side of the sliding block is provided with a positioning rod. The outer side of the positioning rod is provided with a positioning spring. The end of the positioning spring away from the sliding block is provided with a fixing part.

[0020] The leveling component is located at the bottom of the threaded rod two and is used to measure the levelness of the upper and lower cutters.

[0021] Preferably, the planarization assembly includes a fixed plate, a connecting plate, a connecting shaft, and a protractor;

The end of the connecting shaft is connected to the side of the connecting plate. The protractor is located on the outside of the connecting shaft and on the side of the measuring rod.

[0023] Compared with the prior art, the present invention has the following beneficial technical effects:

[0024] 1. By adjusting the settings of the cutting mechanism, the motor drives the threaded rod to move, thereby adjusting the position of the lower cutter according to the size of the spring. This ensures that the lower cutter always abuts against the bottom of the spring. Then, the cylinder is activated to drive the upper cutter to move downward quickly to cut the spring. This provides a stable physical support point for the cutting process. The spring will not shift or deflect due to uneven force when it is cut, ensuring that the cutting position strictly conforms to the preset size. In addition, the motor drives the threaded rod to rotate through the synchronous pulley and synchronous belt, which can reduce the vibration effect when the threaded rod rotates, thereby avoiding the accumulation of errors in the reading of the threaded rod after long-term use and improving the accuracy of cutting.

[0025] 2. By using the leveling mechanism, rotating the threaded rod and sliding the sliding block can move the leveling rod to the vicinity of the upper or lower cutter. The leveling rod then measures the horizontality of the blades of the upper and lower cutters, allowing for real-time detection of the parallelism between the upper and lower cutters. This ensures that the two blades fit together perfectly during cutting, preventing tilting of the cut surface, burrs, or spring deformation due to excessive gaps. Furthermore, it allows for early identification and adjustment of the blade position, ensuring even distribution of cutting force, reducing vibration amplitude, extending equipment life, and improving the working environment. It also enables timely detection of blade wear or deformation, allowing for early replacement or repair of the cutters and preventing cutting failures caused by blade damage.

[0033] Example 1

[0034] like Figures 1-3 As shown, the present invention proposes a conveniently adjustable spring machine cutting assembly, including a spring machine body 1, a discharge port 2 disposed on the spring machine body 1, an adjustable cutting mechanism, an upper cutter 304, a leveling mechanism, and a leveling rod 413.

[0035] The adjusting cutting mechanism is located on the side of the spring machine body 1 and is used to adjust the cutting position according to the size of the spring;

[0036] The upper cutter 304 is mounted on the adjusting cutting mechanism and located above the discharge port 2. The upper cutter 304 is a movable cutter that moves quickly during the cutting process to cut the spring. The lower cutter 313 is located below the discharge port 2. Before cutting the spring, the lower cutter 313 moves under the control of the adjusting cutting mechanism to move to the working position according to the size of the spring. Then it stays in the working position to support the bottom of the spring and assist the upper cutter 304 in the cutting work.

[0037] The leveling mechanism is located on the side of the adjusting cutting mechanism and is used to measure the levelness of the upper cutter 304 and the lower cutter 313;

[0038] The leveling rod 413 is rotatably mounted on the leveling mechanism. A marking block 415 is provided on the side of the leveling rod 413, and an infrared emitter 416 is provided at the end of the leveling rod 413. The infrared emitter 416 emits infrared rays to illuminate the upper cutter 304 and the lower cutter 313. When the infrared rays are aligned with the end of the cutter, the leveling rod 413 is moved. If the angle of the leveling rod 413 deviates during the movement, it proves that the levelness of the cutter is inaccurate, and the cutter is adjusted accordingly.

[0039] The adjusting cutting mechanism includes a cutting assembly and an adjusting assembly. The cutting assembly is located on the side of the spring machine body 1 and in the upper part, and is used to quickly move and cut the spring. The adjusting assembly is located on the side of the spring machine body 1 and in the lower part, and is used to adjust the contact position of the lower cutter 313 according to the size of the spring. The cutting assembly includes a fixing frame 301, a cylinder 302, and a push rod 303. The fixing frame 301 is located on the top of the spring machine body 1, the cylinder 302 is located inside the fixing frame 301, and the push rod 303 is located at the output end of the cylinder 302. The bottom of the push rod 303 is connected to the top of the upper cutter 304. When the cylinder 302 is activated, the cylinder 302 drives the push rod 303 to move, and the push rod 303 drives the upper cutter 304 to move quickly, thereby cutting the spring. The adjustment assembly includes a second fixing frame 305, a motor 314, a rotating shaft 306, and a first synchronous pulley 307. The second fixing frame 305 is located on the side of the spring machine body 1, the motor 314 is located inside the second fixing frame 305, the rotating shaft 306 is located at the output end of the motor 314, the first synchronous pulley 307 is located on the top of the rotating shaft 306, a synchronous belt 308 is located on the outer side of the first synchronous pulley 307, a second synchronous pulley 309 is located on the side of the synchronous belt 308 away from the first synchronous pulley 307, the bottom of the second synchronous pulley 309 is fixedly connected to the outer side of the spring machine body 1, and a threaded rod is located on the top of the second synchronous pulley 309. A sliding frame 311 is threaded on the outer side of the threaded rod 310. A slide rail 312 is slidably mounted on the outer side of the sliding frame 311. The top of the sliding frame 311 is connected to the bottom of the lower cutter 313. When the motor 314 is started, the motor 314 drives the synchronous pulley 307 to rotate through the rotating shaft 306. The synchronous pulley 307 drives the synchronous pulley 309 to rotate through the synchronous belt 308. The synchronous pulley 309 drives the threaded rod 310 to rotate. When the threaded rod 310 rotates, it drives the sliding frame 311 to slide on the slide rail 312, thereby driving the lower cutter 313 to move below the spring for fixing.

[0040] Example 2

[0041] like Figures 4-6As shown, this utility model proposes a spring cutting assembly that is easy to adjust. Compared with Embodiment 1, this embodiment details the structure of the leveling mechanism.

[0042] The leveling mechanism includes a second slide rail 401, a positioning hole 402, a sliding block 403, a second threaded rod 404, and a leveling assembly. The second slide rail 401 is mounted on the spring mechanism body 1. The positioning hole 402 is located at the end of the second slide rail 401, and there are two positioning holes symmetrically arranged about the second slide rail 401. The sliding block 403 is slidably mounted on the second slide rail 401. The second threaded rod 404 is threaded onto the inner side of the sliding block 403. A rotating rod is located at the top of the second threaded rod 404 to drive the second threaded rod 404 to rotate on the sliding block 403. A positioning rod 405 is slidably mounted on the inner side of the sliding block 403. A positioning spring 406 is located on the outer side of the positioning rod 405. A fixing member 408 is located at the end of the positioning spring 406 away from the sliding block 403. The inner side of the fixing member 408 and the outer side of the positioning rod 405 are slidably connected. The bottom of the fixing member 408 is connected to the side of the sliding block 403. A pull rod 407 is provided at the end of the positioning rod 405 away from the sliding block 403. Pulling the pull rod 407 makes it disengage from the positioning hole 402. At this time, the sliding block 403 can be controlled to slide on the slide rail 401. After the sliding block 403 is moved to the appropriate position, the pull rod 407 is released. Under the action of the positioning spring 406, the positioning rod 405 is inserted into the positioning hole 402 at this location to fix the sliding block 403. When the positioning rod 405 is in the positioning hole 402 on the right side, the levelness of the upper cutter 304 and the lower cutter 313 can be measured. When it is in the positioning hole 402 on the left side, it is disengaged from the slitting blade and will not affect the spring cutting operation. The leveling component is set at the bottom of the threaded rod 404 and is used to measure the levelness of the upper cutter 304 and the lower cutter 313. The leveling assembly includes a fixed plate 409, a connecting plate 410, a connecting shaft 411, and a protractor 412. The fixed plate 409 is located at the bottom of the threaded rod 404, and the connecting plate 410 is located on the side of the fixed plate 409. Two fixed plates 409 are symmetrically arranged about the connecting plate 410. A return spring 414 is located at the bottom of the fixed plate 409, with one end of the return spring 414 away from the fixed plate 409 connected to the side of the leveling rod 413. The connecting shaft 411 is rotatably mounted on the inner side of the leveling rod 413, and its end is connected to the side of the connecting plate 410. The protractor 412 is located on the outer side of the connecting shaft 411 and on the side of the leveling rod 413. The protractor 412 is equipped with a scale, and multiple scales are arranged in a ring around the protractor 412. The end of the marker block 415 is in contact with the protractor 412. When the measuring rod 413 rotates, it drives the marker block 415 to rotate. When the measuring rod 413 contacts the upper cutter 304 or the lower cutter 313, if the upper cutter 304 or the lower cutter 313 is tilted, it will squeeze the measuring rod 413 and drive it to rotate on the connecting shaft 411. When it rotates to the specified position, the marker block 415 rotates on the protractor 412 to indicate the scale, so that the tilt angle can be determined, and then the upper cutter 304 or the lower cutter 313 can be repaired. After the measurement is completed, the reset spring 414 drives the measuring rod 413 to return to its original position.

[0043] In summary, when using this utility model, the position of the lower cutter 313 is adjusted according to the size of the produced spring. The motor 314 is started, and the motor 314 drives the synchronous pulley 307 to rotate via the rotating shaft 306. The synchronous pulley 307 drives the synchronous pulley 309 to rotate via the synchronous belt 308. The synchronous pulley 309 drives the threaded rod 310 to rotate. When the threaded rod 310 rotates, it drives the sliding frame 311 to slide on the slide rail 312, thereby driving the lower cutter 313 to abut against the bottom of the spring for fixation. Then, the levelness of the upper cutter 304 and the lower cutter 313 is measured. The pull rod 407 is pulled to disengage it from the positioning hole 402, and the sliding block 403 is controlled to slide on the slide rail 401. After the sliding block 403 is moved to the positioning hole 402 on the right side, the pull rod 407 is released, and the positioning rod 405 is positioned on the positioning spring 406. The sliding block 403 is fixed in the positioning hole 402 under the action, so that the measuring rod 413 is directly below the upper cutter 304. Then, the threaded rod 404 is rotated, and the threaded rod 404 drives the measuring rod 413 to move up and down until the infrared light emitted by the infrared emitter 416 is level with the blade of the upper cutter 304. At this time, the blade of the upper cutter 304 abuts against the top of the measuring rod 413. If the blade of the upper cutter 304 is tilted, it will drive the measuring rod 413 to rotate. The measuring rod 413 displays the tilt angle on the protractor 412 through the marking block 415. Then, the measuring rod 413 is moved to the blade of the lower cutter 313 for measurement and marking. If there is no problem with the levelness measurement, the measuring rod 413 is removed and the cylinder 302 is started. The cylinder 302 drives the upper cutter 304 to move quickly and cut the spring.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
