Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel micro wire processing, and particularly to a stainless steel micro wire straightening and cutting device. Background Art

[0002] Stainless steel micro wires are gradually drawn from thick steel wires to the target diameter through multiple cold drawing passes, and the surface finish and dimensional accuracy need to be controlled. They are widely used in industrial filtration, textiles and composites, medical fields, electronics and energy, etc.

[0003] Chinese Patent with the publication number CN115069930A provides a numerically controlled wire straightening and cutting machine. The numerically controlled wire straightening and cutting machine in the present invention includes a base, a conveying device, a straightening device, a length setting device, a cutting device and a control system. The conveying device unrolls the coiled wire, and the wire passes through the center of the straightening device. The straightening wheels rotate at high speed to straighten the bent wire; the straightened wire enters the length setting device. The speed measuring wheel accurately measures the speed of the wire and sends corresponding signals according to the set length to control the cutting time of the cutter; the cutting device performs corresponding cutting actions according to the control signals given by the control system; the digital control system precisely controls each device and sets various parameters on the operation screen; the newly developed cutting machine in the present invention adopts a digital control system, and the product length is set by the control panel for precise control. It adopts a synchronous cutting device to solve problems such as large vibration and noise, as well as jamming and continuous cutting. Since the difference between stainless steel micro wires and other stainless steel pipes or steel materials lies in that the diameter of stainless steel micro wires is relatively thin and they are prone to deformation. After the existing stainless steel micro wire straightening and cutting device straightens and cuts the stainless steel micro wires, the stainless steel micro wire segments fall into the collection box below. When the stainless steel micro wire segments fall into the collection box under the influence of gravity and collide with other stainless steel micro wires in the box, not only noise is generated, but also the stainless steel micro wire segments are prone to deformation, affecting the subsequent use of the stainless steel micro wire segments.

The output end of the motor is fixedly sleeved with a rotating plate. The bottom of the rotating plate is fixedly installed with a second magnet.

[0010] As a further improvement of the present invention, the bottom of the rotating plate is in an arc shape, and the shape of the second magnet is adapted to the bottom of the rotating plate.

[0011] As a further improvement of the present invention, the rotating plate is located between the motor and the loose gear. The second magnet is located directly below the first magnet. The magnetic poles at the bottom of the second magnet and the bottom of the first magnet are the same.

[0012] As a further improvement of the present invention, a bottom plate is fixedly installed at the bottom end of the lifting box. A telescopic airbag is arranged in the lifting box between the first magnet and the bottom plate.

When the stainless steel micro wire is cut by the micro wire cutting assembly, since the silicon steel sheets and the permanent magnets are arranged in the speed reducing box and the silicon steel sheets and the permanent magnets form a closed magnetic circuit, when the stainless steel micro wire passes through at a high speed, its conductive property triggers the eddy current effect, generating a Lorentz force opposite to the moving direction to form damping. Since the speed reducing box is in a gradually shrinking shape, the stainless steel micro wire triggers the magnetoresistive bistable switching at the critical speed. When the stainless steel micro wire passes through at a low speed, the damping is small and the guide groove remains in an open state; when the stainless steel micro wire rebounds at a high speed, the eddy current damping suddenly increases, the speed reducing box enters a locked state, forcing the stainless steel micro wire to decelerate and stabilize on a preset path, achieving the effect of soft landing of the stainless steel micro wire, not only reducing the noise generated by the collision between the stainless steel micro wires, but also avoiding the deformation of the stainless steel micro wires caused by the collision between them.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Example 1, please refer to Figures 1-5 , the present invention provides a straightening and cutting device for stainless steel micro wires, including: A micro wire straightening machine 1, a side plate 2 is arranged on one side of the micro wire straightening machine 1, a cutting frame 3 is fixedly installed on one side of the side plate 2, a micro wire cutting component 4 is arranged on one side of the side plate 2 above the cutting frame 3, and a straightening shaft wheel 5 is arranged on the front side of the micro wire straightening machine 1; The intermittent conveying assembly 6 is arranged below the cutting frame 3, and a stainless steel micro wire collection box 10 is placed on the top of the intermittent conveying assembly 6; The micro wire speed reducing assembly 7 is arranged on the top of the intermittent conveying assembly 6. The micro wire speed reducing assembly 7 is connected to the cutting frame 3 through a lifting and box changing assembly 8. The micro wire speed reducing assembly 7 includes a speed reducing box 701, silicon steel sheets 702 and permanent magnets 703. The inner walls of the speed reducing box 701 are respectively fixedly installed with silicon steel sheets 702 and permanent magnets 703, and the silicon steel sheets 702 and permanent magnets 703 are staggered and distributed on the inner wall of the speed reducing box 701.

[0021] The side cross section of the speed reducing box 701 is in a horn shape. The lower part of the speed reducing box 701 is sleeved outside the stainless steel micro wire collection box 10 directly below. The number of the silicon steel sheets 702 and permanent magnets 703 is several. Several silicon steel sheets 702 and permanent magnets 703 are evenly distributed in several circles along the inner wall of the speed reducing box 701, and the number of the silicon steel sheets 702 and permanent magnets 703 gradually decreases from top to bottom. By arranging the speed reducing box 701, silicon steel sheets 702 and permanent magnets 703 below the cutting frame 3, when the stainless steel micro wire is cut by the micro wire cutting assembly 4, since the silicon steel sheets 702 and permanent magnets 703 are arranged in the speed reducing box 701, the silicon steel sheets 702 and permanent magnets 703 form a closed magnetic circuit. When the stainless steel micro wire passes through at a high speed, its conductive property triggers the eddy current effect, generating a Lorentz force opposite to the moving direction, forming a damping. Since the speed reducing box 701 is in a gradually shrinking shape, the stainless steel micro wire triggers the magnetoresistive bistable switching at the critical speed. When the stainless steel micro wire passes through at a low speed, the damping is small and the guide groove remains in an open state; when the stainless steel micro wire rebounds at a high speed, the eddy current damping suddenly increases, the speed reducing box 701 enters a locked state, forcing the stainless steel micro wire to decelerate and stabilize on a preset path, achieving the effect of the soft landing of the stainless steel micro wire, not only reducing the noise generated by the collision between the stainless steel micro wires, but also avoiding the situation of deformation generated by the collision between the stainless steel micro wires.

[0022] Embodiment 2, please refer to Figures 1-7 , the intermittent conveying assembly 6 includes a conveyor belt machine 601, a motor 602, a transmission gear 603 and a loose gear 604. The motor 602 is fixedly installed on the side of the cutting frame 3. A conveyor belt machine 601 is arranged on one side of the micro wire straightening machine 1. The output end of the motor 602 is fixedly sleeved with a loose gear 604. The rotating shaft on the conveyor belt machine 601 is fixedly sleeved with a transmission gear 603. The external teeth of the loose gear 604 are meshed with the external teeth of the transmission gear 603. Several stainless steel micro wire collection boxes 10 are placed on the top of the conveyor belt machine 601.

[0023] The lifting and box-changing assembly 8 includes a lifting box 801, a lifting rod 802, a connecting plate 803, a first magnet 804, a return spring 805, a rotating plate 806 and a second magnet 807. A lifting box 801 is fixedly installed on the side of the cutting frame 3 and the micro wire straightening machine 1 facing each other. The inner cavity of the lifting box 801 is movably sleeved with a lifting rod 802. The top end of the lifting rod 802 penetrates through the upper wall of the lifting box 801 and is fixedly installed with a connecting plate 803. One side of the connecting plate 803 is fixedly installed on the side of the speed reduction box 701. The bottom of the lifting rod 802 is fixedly installed with a first magnet 804. The first magnet 804 is slidably installed in the lifting box 801. The outer side of the lifting rod 802 is movably sleeved with a return spring 805. The two ends of the return spring 805 are respectively fixedly installed on the top of the first magnet 804 and the top of the inner cavity of the lifting box 801. The output end of the motor 602 is fixedly sleeved with a rotating plate 806. The bottom of the rotating plate 806 is fixedly installed with a second magnet 807.

[0024] The bottom of the rotating plate 806 is in an arc shape. The shape of the second magnet 807 is adapted to the bottom of the rotating plate 806. The magnetic pole at the bottom of the second magnet 807 is the same as the magnetic pole at the bottom of the first magnet 804. The rotating plate 806 is located between the motor 602 and the loose gear 604. The second magnet 807 is located directly below the first magnet 804.

[0025] The motor 602 is used as a drive to drive the loose gear 604 to rotate. Since the loose gear 604 meshes with the transmission gear 603, the conveyor belt 601 is driven to move intermittently, facilitating the intermittent conveyance of the new stainless steel micro wire collection box 10 to the lower part of the cutting frame 3. Since the motor 602 is also provided with a rotating plate 806, when the motor 602 drives the rotating plate 806 to rotate, the second magnet 807 is rotated to the lower part of the first magnet 804. The second magnet 807 and the first magnet 804 generate a repulsive force, pushing the first magnet 804 and the lifting rod 802 upward, driving the connecting plate 803 and the speed reduction box 701 to move upward. This facilitates the lifting of the speed reduction box 701 when the motor 602 conveys the new stainless steel micro wire collection box 10 to the lower part of the cutting frame 3. At the same time, when the new stainless steel micro wire collection box 10 is conveyed to the lower part of the cutting frame 3, the second magnet 807 moves away from the lower part of the first magnet 804. Using the elastic force of the return spring 805, the speed reduction box 701 is reset and covers the outside of the new stainless steel micro wire collection box 10 for use.

[0026] A bottom plate 808 is fixedly installed at the bottom end of the lifting box 801. The length of the bottom plate 808 is less than that of the first magnet 804. The bottom plate 808 does not obstruct the magnetic repulsion force between the second magnet 807 and the first magnet 804. An expansion airbag 809 is arranged in the lifting box 801 between the first magnet 804 and the bottom plate 808. Two ends of the expansion airbag 809 are respectively fixedly connected to the first magnet 804 and the bottom plate 808. An air filling valve 810 is fixedly communicated with the top end of the side wall of the expansion airbag 809. A pressure relief valve 811 is fixedly installed on the side wall of the bottom plate 808. The pressure relief valve 811 is communicated with the expansion airbag 809, and the air outlet of the pressure relief valve 811 faces towards the stainless steel micro wire collecting box 10.

[0027] When the second magnet 807 and the first magnet 804 generate a mutual repulsion force to push the first magnet 804, the lifting rod 802, the connecting plate 803 and the speed reducing box 701 upwards, the first magnet 804 drives the top end of the expansion airbag 809 to move upwards, so that the expansion airbag 809 is stretched, and external gas enters the expansion airbag 809 from the air filling valve 810 to fill the expansion airbag 809. When the second magnet 807 moves away from below the first magnet 804 and the speed reducing box 701 resets, the expansion airbag 809 is synchronously squeezed, and the gas in the expansion airbag 809 slowly leaks from the pressure relief valve 811, thereby reducing the descending speed of the speed reducing box 701 and preventing the speed reducing box 701 from hitting the stainless steel micro wire collecting box 10 or the conveyor belt 601. At the same time, the gas discharged from the expansion airbag 809 blows into the stainless steel micro wire collecting box 10 newly entering the speed reducing box 701 to blow and clean the inner wall of the stainless steel micro wire collecting box 10, preventing fixed particles from existing in the stainless steel micro wire collecting box 10 and squeezing the stainless steel micro wires, resulting in indentations on the surface of the stainless steel micro wires.

[0028] Example three, please refer to Figure 1 and Figure 6 A wheel cleaning assembly 9 is arranged on the front side of the straightening shaft wheel 5. The wheel cleaning assembly 9 includes a connecting frame 901, a movable opening 902, a mounting frame 903, a storage plate 904 and a cleaning brush 905. A connecting frame 901 is fixedly installed on the other side of the speed reducing box 701. A movable opening 902 is formed in the lower part of the side plate 2. One side of the connecting frame 901 passes through the movable opening 902 to be connected with the mounting frame 903. A storage plate 904 is fixedly installed on the rear side of the mounting frame 903. A cleaning brush 905 is fixedly installed on the side of the storage plate 904 close to the straightening shaft wheel 5, and the cleaning brush 905 does not contact the straightening shaft wheel 5.

[0029] A square opening is formed at the top of the cleaning brush 905. The storage plate 904 is located below one side of the straightening shaft wheel 5, and the storage plate 904 and the straightening shaft wheel 5 are in the same vertical plane.

[0030] On the other side of the speed reducer box 701, there is a shaft wheel cleaning assembly 9. While the speed reducer box 701 is controlled by the lifting and cassette-changing assembly 8 to move upward, it can drive the connecting frame 901 to move upward, thereby driving the mounting frame 903, the storage plate 904, and the cleaning brush 905 to move upward. At this time, the cleaning brush 905 is located on the side wall of the straightening shaft wheel 5. When the straightening shaft wheel 5 rotates, with the cleaning brush 905 provided on the side, it is convenient to clean the impurities in the groove of the straightening shaft wheel 5, avoiding the adhesion of impurities in the groove of the straightening shaft wheel 5 and affecting the straightening effect of the stainless steel micro wire.

[0031] Working principle: Please refer to Figures 1-7 , when using this device, pass the stainless steel micro wire through the straightening shaft wheel 5. Use the straightening shaft wheel 5 of the micro wire straightening machine 1 to straighten and convey the stainless steel micro wire, and convey the stainless steel micro wire to the lower part of the micro wire cutting assembly 4. Use the micro wire cutting assembly 4 to cut it. The cut stainless steel micro wire segments fall downward under the influence of gravity and enter the speed reducer box 701. Since there are silicon steel sheets 702 and permanent magnets 703 in the speed reducer box 701, the silicon steel sheets 702 and the permanent magnets 703 form a closed magnetic circuit. When the stainless steel micro wire passes through at high speed, its conductive characteristics trigger the eddy current effect, generating a Lorentz force opposite to the direction of motion, forming a damping. Since the speed reducer box 701 is in a tapered shape, the stainless steel micro wire triggers the magnetoresistive bistable switching at the critical speed. When the stainless steel micro wire passes through at low speed, the damping is small and the guide groove remains open; when the stainless steel micro wire rebounds at high speed, the eddy current damping suddenly increases, and the speed reducer box 701 enters the locked state, forcing the stainless steel micro wire to decelerate and stabilize on the preset path, achieving the effect of the soft landing of the stainless steel micro wire, not only reducing the noise generated by the collision between the stainless steel micro wires, but also avoiding the deformation caused by the collision between the stainless steel micro wires; The motor 602 is used as a drive to drive the loose gear 604 to rotate. Since the loose gear 604 meshes with the transmission gear 603, the conveyor belt 601 is driven to move intermittently, and the new stainless steel micro wire collection box 10 is intermittently conveyed below the cutting frame 3. When a certain amount of stainless steel micro wire segments are collected in the stainless steel micro wire collection box 10 in the speed reduction box 701, the motor 602 is used to drive the new stainless steel micro wire collection box 10 to enter below the micro wire cutting assembly 4. Since there is also a rotating plate 806 on the motor 602, when the loose gear 604 rotates to a position about to mesh with the transmission gear 603, the outside of the second magnet 807 at the bottom of the rotating plate 806 first rotates below the first magnet 804. The second magnet 807 and the first magnet 804 generate a repulsive force, pushing the first magnet 804 and the lifting rod 802 upward, driving the connecting plate 803 and the speed reduction box 701 to move upward. When the motor 602 conveys the new stainless steel micro wire collection box 10 below the cutting frame 3, the speed reduction box 701 is located above the stainless steel micro wire collection box 10. When the stainless steel micro wire collection box 10 is conveyed below the micro wire cutting assembly 4 and the conveyor belt 601 stops moving, at this time, as the motor 602 rotates, the second magnet 807 moves away from below the first magnet 804. Using the elastic force of the return spring 805, the speed reduction box 701 resets, covering the outside of the new stainless steel micro wire collection box 10 for use. It can not only quantitatively divide and pack the stainless steel micro wire segments, but also automatically convey the new stainless steel micro wire collection box 10 into the speed reduction box 701 for use; Moreover, when the second magnet 807 and the first magnet 804 generate a repulsive force and push the first magnet 804, the lifting rod 802, the connecting plate 803 and the speed reduction box 701 upward, the first magnet 804 drives the top of the telescopic airbag 809 to move upward, thereby stretching the telescopic airbag 809. External gas enters the telescopic airbag 809 from the air supply valve 810 to supply air to the telescopic airbag 809. When the second magnet 807 moves away from below the first magnet 804 and the speed reduction box 701 resets, the telescopic airbag 809 is synchronously squeezed, and the gas in the telescopic airbag 809 slowly leaks from the pressure relief valve 811, thereby reducing the downward movement speed of the speed reduction box 701 and preventing the speed reduction box 701 from hitting the stainless steel micro wire collection box 10 or the conveyor belt 601; At the same time, the gas discharged from the telescopic airbag 809 blows into the newly entered stainless steel micro wire collection box 10 in the speed reduction box 701 to blow and clean the inner wall of the stainless steel micro wire collection box 10, preventing fixed particles from existing in the stainless steel micro wire collection box 10 and squeezing the stainless steel micro wire, resulting in indentations on the surface of the stainless steel micro wire; On the other side of the speed reducer box 701, there is a shaft wheel cleaning assembly 9. While the speed reducer box 701 is controlled by the lifting and cassette changing assembly 8 to move upward, it can drive the connecting frame 901 to move upward, thereby driving the mounting frame 903, the storage plate 904, and the cleaning brush 905 to move upward. When the straightening shaft wheel 5 rotates, with the cleaning brush 905 provided on the side, it is convenient to clean the impurities in the grooves of the straightening shaft wheel 5, so that the impurities outside the straightening shaft wheel 5 enter the square openings on the storage plate 904 for storage, facilitating subsequent cleaning.
