Description

Technical Field

[0001] This utility model relates to the field of electronic components, and in particular to a coil punching and shearing die. Background Technology

[0002] As is well known, electronic components such as electromagnets and inductors require coils made of wound wire. Typically, after the coil is wound, its leads need to be trimmed to give the coil neat leads for electrical connections. Currently, the trimming of coil leads is mainly done using molds. However, existing molds often fail to properly trim the leads due to errors in the coil's position or orientation. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a coil punching and shearing die, which can smoothly and accurately perform punching and shearing operations on coils.

[0004] According to a first aspect of the present invention, a coil punching and shearing die includes: a fixed die base, a movable die base, a feeding mechanism, a die-forming mechanism, and a positioning mechanism. The fixed die base is provided with a working position and a blanking area, the blanking area being located below the working position. The movable die base is movably connected to the fixed die base, and the movable die base is provided with a punch that can move closer to or away from the fixed die base. The feeding mechanism is connected to the fixed die base through the die-forming mechanism, the feeding mechanism being used to transport materials to the working position, and the die-forming mechanism being used to organize the materials. The positioning mechanism includes a positioning rod and a material-supporting assembly, the material-supporting assembly being able to support or move the materials at the working position, and the positioning rod being able to penetrate the materials and support and position them.

[0005] The coil punching and shearing die according to this utility model embodiment has at least the following beneficial effects: After the feeding mechanism conveys the material to the die-forming mechanism, the die-forming mechanism can perform preliminary position and orientation adjustment on the material, and then convey the adjusted material to the working position. When the material is conveyed to the working position, the material support assembly first supports the material so that the material can stay at the working position. Then, the positioning rod will move and penetrate into the material, thereby achieving the effect of positioning and supporting the material through the positioning rod, and allowing the moving die base to drive the punch to move closer to the material, thereby achieving the effect of punching and shearing the wires of the material. During this process, the material support assembly can leave the working position. After the punching and shearing operation of the material is completed, the positioning rod can retract, and the material will fall into the dropping area under its own weight, so as to facilitate the material recycling operation.

[0006] The mold-forming mechanism makes initial adjustments to the position and orientation of the material, and the positioning rod positions the adjusted material. Therefore, the material can be accurately positioned and supported at the working position, which ensures that the punch can accurately cut off the wires of the material during punching and shearing. This can effectively improve the yield of the finished coil and enhance the quality of the punching and shearing operation for the wires.

[0007] According to some embodiments of the present invention, the feeding mechanism includes a vibratory feeder, the fixed mold base is connected to a material support base, the material support base is located at the end of the working position and docks with it, and the vibratory feeder is connected to the material support base; the mold assembly includes an insert assembly, which can fix and position the material on the material support base.

[0037] Reference Figure 1 , Figure 3 and Figure 4A coil punching and shearing die includes: a fixed die base 100, a movable die base 900, a feeding mechanism 800, a die-forming mechanism 700, and a positioning mechanism 500. The fixed die base 100 is provided with a working position 130 and a blanking area 150, the blanking area 150 being located below the working position 130. The movable die base 900 is movably connected to the fixed die base 100, and is provided with a punch 980 that can move closer to or away from the fixed die base 100. The feeding mechanism 800 is connected to the fixed die base 100 through the die-forming mechanism 700, and is used to transport materials to the working position 130. The die-forming mechanism 700 is used to organize the materials. The positioning mechanism 500 includes a positioning rod 550 and a material-supporting assembly 530, the material-supporting assembly 530 being able to support or remove the materials at the working position 130, and the positioning rod 550 being able to penetrate the materials and support and position them. After the feeding mechanism 800 conveys the material to the die-forming mechanism 700, the die-forming mechanism 700 can perform preliminary position and orientation adjustments on the material and then convey the adjusted material to the working position 130. When the material is conveyed to the working position 130, the material support assembly 530 first supports the material so that it can stay at the working position 130. Then, the positioning rod 550 will move and penetrate into the material, thereby achieving the effect of positioning and supporting the material through the positioning rod 550, and allowing the moving die base 900 to drive the punch 980 to move closer to the material, thereby achieving the effect of punching and shearing the threads of the material. During this process, the material support assembly 530 can leave the working position 130. After the punch 980 finishes its punching and shearing operation on the material, the positioning rod 550 can retract, allowing the material to fall into the drop area 150 under its own weight for material recovery. The mold-forming mechanism 700 makes initial adjustments to the position and orientation of the material, and the positioning rod 550 positions the adjusted material. Therefore, the material can be accurately positioned and supported at the working position 130, which ensures that the punch 980 can accurately cut off the wires of the material during punching and shearing. This can effectively improve the yield of the finished coil and enhance the quality of the punching and shearing operation for the wires.

[0038] Specifically, the moving mold base 900 is connected to a drive device 950, which drives the moving mold base 900 to move up and down, thereby driving the punch 980 to move closer to or away from the working position 130.

[0039] It is conceivable that the drive device 950 can be a hydraulic cylinder or a pneumatic cylinder, etc. The specific implementation method is not unique, but can be adjusted according to the actual situation, and is not limited here.

[0040] In some embodiments, reference is made to Figure 1The feeding mechanism 800 includes a vibratory feeder, and a fixed mold base 100 is connected to a material support 750. The material support 750 is located at the end of the working position 130 and docks with it. The vibratory feeder is connected to the material support 750. The mold-forming mechanism 700 includes an insert assembly 710, which can fix and position the material on the material support 750. After the vibratory feeder supplies the material, the material will be conveyed to the material support 750 one by one and arranged on the material support 750. After the material enters the material support 750, the insert assembly 710 can fix and position the material on the material support 750, so that the material can be arranged on the material support 750 in a predetermined position and orientation for subsequent material retrieval.

[0041] Specifically, the material support 750 is equipped with a track, and the vibratory feeder is connected to the track to transport materials. The width of the track is adapted to the width of the material. The fixed mold base 100 is equipped with a lifting plate, and the material support 750 is installed on the lifting plate and can be raised and lowered, so that the material can be moved up and down relative to the insert assembly 710, thereby facilitating the insert assembly 710 to apply force and position the material.

[0042] In some embodiments, reference is made to Figure 5 The insert assembly 710 includes an insert cylinder 713 and an insert gear assembly 715. The insert cylinder 713 is connected to the insert gear assembly 715 and can drive it to move and penetrate into the material or between two adjacent materials. A mounting plate 720 is movably mounted on the fixed mold base 100, and a material support 750 is located on the mounting plate 720 and can rise or fall with it. The material, acting as a coil, will have gaps between different numbers of turns. After the insert cylinder 713 drives the insert gear assembly 715 to move, the insert gear assembly 715 can move and penetrate into the gaps in the material, thereby achieving the effect of fixing and positioning the material, and thus facilitating the adjustment of the material. The mounting plate 720 can be raised and lowered, allowing the material support 750 to move up and down relative to the vibratory feeder, thus facilitating accurate docking of the vibratory feeder with the material support 750.

[0043] In some embodiments, reference is made to Figure 6The material support 750 is movably equipped with an anti-rotation plate 740 and / or a baffle plate 730. The anti-rotation plate 740 and / or baffle plate 730 can move closer to and abut against the material, and can also move away from the material. When the insert gear assembly 715 penetrates the material and pushes it to rotate, the material's threads will rotate. After the anti-rotation plate 740 moves closer to the material, it can abut against and block the protruding threads, thereby hindering the material's rotation and achieving the effect of preventing rotation and angular positioning. The baffle plate 730 can block the material, preventing it from detaching from the material support 750, thus improving the stability of the material during conveying and molding processes.

[0044] In some embodiments, reference is made to Figure 2 There are two insert components 710, located on opposite sides of the material support 750. An anti-rotation plate 740 and one of the insert components 710 are located on the same side of the material support 750. A baffle plate 730 and the other insert component 710 are also located on the same side of the material support 750. The two insert components 710 can position and adjust the material from both sides, ensuring that the material can evenly bear the applied force, thus preventing imbalance and positional deviation caused by uneven force. The baffle plate 730 and anti-rotation plate 740 are located on opposite sides of the material, preventing mutual interference during movement and improving overall stability.

[0045] Specifically, the baffle plate 730 and the anti-rotation plate 740 are each connected to a cylinder and move under the drive of the cylinder.

[0046] In some embodiments, reference is made to Figure 7 The positioning mechanism 500 includes a first cylinder 510, a second cylinder 520, and a push block 560 connected in sequence. The first cylinder 510 can drive the push block 560 to move along the length direction of the positioning rod 550, and the second cylinder 520 can drive the push block 560 to move along the width direction of the positioning rod 550. The first cylinder 510 can drive the positioning rod 550 to move through the push block 560. The second cylinder 520 can drive the push block 560 and the positioning rod 550 to move away from each other and be misaligned. The positioning rod 550 is connected to a return spring. After the second cylinder 520 drives the push block 560 to move until it coincides with the positioning rod 550, the first cylinder 510 can be activated and drive the positioning rod 550 to move through the push block 560, so that the positioning rod 550 can smoothly extend into the material. After the material is punched and sheared, the second cylinder 520 can drive the push block 560 to move away from the positioning rod 550. At this time, the positioning rod 550 will be immediately driven by the reset spring and elastically move away from the working position 130, so that the material can fall into the material dropping area 150 in time under its own weight, so as to facilitate the material recycling operation.

[0047] It is foreseeable that the resetting degree of the positioning rod 550 is limited, and the push block 560 can move to the limited position of the resetting degree under the drive of the first cylinder 510, so that the push block 560 can smoothly contact the positioning rod 550.

[0048] In some embodiments, reference is made to Figure 8 The material support assembly 530 includes a detection element 575 and a positioning block 573. The detection element 575 is installed on the positioning block 573, which can move to or away from the working position 130. Below the working position 130, there is a material support block 535 and a material support cylinder 533. The material support cylinder 533 is connected to the material support block 535 and can move it closer to or away from the working position 130. Before the material is conveyed to the working position 130, the positioning block 573 will be positioned at the working position 130 to receive the material promptly. After the positioning block 573 receives the material, the detection element 575 will detect the material's arrival and drive the positioning rod 550 to move and penetrate into the material, thus allowing the positioning rod 550 to be smoothly positioned with the material. Afterwards, the positioning block 573 can leave the working position 130, allowing the material to fall smoothly into the discharge area 150 after the punching and shearing operation.

[0049] Specifically, the detection component 575 is a positioning detection fiber, and the positioning block 573 is connected to a third cylinder 577. The third cylinder 577 can drive the positioning block 573 to move relative to the working position 130, thereby achieving the effect of the positioning block 573 moving to or away from the working position 130.

[0050] In some embodiments, reference is made to Figure 6 The fixed mold base 100 is equipped with a cover assembly 780 and an ejector assembly 790. The cover assembly 780 covers the working position 130, and the ejector assembly 790 is located at the working position 130 and can press the material from the side. The cover assembly 780 can move to the working position 130 and cover the material except for the threaded parts, thereby preventing the material from detaching from the working position 130 vertically due to impact. The ejector assembly 790 can press the material from the side, thereby preventing the material from coming out from the side due to impact, thus effectively improving the stability of the material during the punching and shearing process.

[0051] Specifically, the cover assembly 780 includes a cover cylinder 783 and a cover plate 785. The cover cylinder 783 is connected to the cover plate 785 and can drive it to move above the working position 130. The top assembly 790 includes a top cylinder 793 and a top pin 795. The top cylinder 793 is connected to the top pin 795 and can drive it to move to the side of the working position 130.

[0052] In some embodiments, reference is made to Figure 9 The punch 980 is vertically mounted on the moving die base 900. The moving die base 900 is provided with a slider 930, which can move to the end of the punch 980 and block the movement of the punch 980. The slider 930 can also move away from the punch 980. Before the punching and shearing operation is completed, the slider 930 can move to the end of the punch 980 and block the punch 980 from moving in the opposite direction, thereby ensuring that the punch 980 can stably and smoothly punch and shear the material. After the punching and shearing operation is completed, the slider 930 can move away from the punch 980, thereby allowing the punch 980 to release the pushing force on the material and the positioning rod 550, thus ensuring that the positioning rod 550 can smoothly retract under the action of the return spring, ensuring that the material can fall smoothly into the material drop area 150.

[0053] Specifically, there are two sliders 930, and each slider 930 is provided with a blocking part. The two blocking parts move from the sides of the punch 980 to approach or move away from the end of the punch 980.

[0054] In some embodiments, reference is made to Figure 10 The fixed mold base 100 is equipped with a sloping insert 770. After the moving mold base 900 moves closer to the fixed mold base 100 and the punch 980 punches and shears the material, the sloping insert 770 can move to push the slider 930 away from the punch 980. During the process of the moving mold base 900 moving closer to the fixed mold base 100, the punch 980 will contact the material and punch and shear it. During this process, the sloping insert 770 will gradually move closer to the slider 930. When the moving mold base 900 moves to the point where the punching and shearing operation is completed, the sloping insert 770 will drive the slider 930 to move, causing the slider 930 to move away from the punch 980, thereby achieving the effect of automatically releasing the punch 980 so that the punch 980 can release the force applied to the positioning rod 550.

[0055] Specifically, the slider 930 is provided with a slanted insertion hole 935, and the slanted insertion block 770 can be inserted into the slanted insertion hole 935 when the moving mold base 900 moves closer to the fixed mold base 100. The slanted insertion block 770 and the slanted insertion hole 935 can be engaged at an angle, thereby pushing the slider 930 to move away from the punch 980.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
