Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core processing, in particular to a magnetic core slitting device after sintering. Background Art

[0002] Ferrite cores are the basic materials for the development of the electronics industry. The ferrite cores currently produced are in the shape of a ring. During the manufacturing process of the ring-shaped cores, after sintering, adjacent ring-shaped cores stick together and need to be cut and separated one by one before they can be used. Usually, the stuck cores are sorted and loaded on an automatic vibrating loading tray and transported to the cutting machine through an inclined feeding guide for cutting and separation.

[0003] The existing cutting machines have a low degree of automation and cannot automatically control the conveying frequency of the magnetic cores when cutting. In order to ensure that the slicer only cuts one magnetic core each time, it is necessary to manually control the sliding speed of the magnetic cores in the feeding guide rail to prevent the cutter from cutting multiple magnetic cores at one time due to the excessively fast conveying frequency, resulting in incomplete separation of the bonded magnetic cores, which requires secondary cutting and separation, thus reducing the cutting efficiency. In addition, the existing feeding guide rail is a single-track conveyor, and the cutter only uses a single knife to cut the magnetic cores on the single track, which further reduces the cutting efficiency and still needs to be improved. Summary of the invention

[0004] The utility model aims at the deficiencies of the prior art and provides an automated and efficient magnetic core cutting device.

[0005] The utility model is realized through the following technical scheme: a magnetic core slitting device after sintering, comprising a workbench, a feeding guide rail is provided at the front end of the workbench, a cutter seat sliding left and right and a fixed seat sliding front and back are provided on the workbench, a slice perpendicular to a discharge port of the feeding guide rail is fixed on the cutter seat, a top rod facing the discharge port of the feeding guide rail is fixed on the fixed seat, and a first driving mechanism and a second driving mechanism are provided on the workbench for respectively driving the cutter seat and the fixed seat to slide.

[0006] The solution uses a push rod to push the end of the bonded magnetic core conveyed by the feeding guide rail to control and limit the magnetic core to prevent the magnetic core from being conveyed too quickly. The cutter seat that slides left and right drives the slice to cut and separate a single magnetic core. The push rod is driven by the fixed seat to slide backward, so that the separated magnetic core between the push rod and the slice falls freely. At this time, the slice slides out, and the subsequent magnetic core is pushed against the push rod again. The fixed seat drives the push rod to slide forward back to the cutting position for the next cutting and separation operation, thereby realizing automated control and cutting of the magnetic core conveying, saving manpower, and greatly improving the cutting efficiency.

[0007] As an optimization, two conveying tracks are arranged on the left and right sides of the feeding guide rail, and two cutting seats are arranged on the left and right sides of the feeding guide rail on the workbench. The two cutting seats are arranged to slide relatively synchronously, and the fixed seat is fixed with two ejector rods facing the discharge ports of the two conveying tracks respectively. The feeding guide rail of this optimization scheme is provided with two sets of conveying tracks, and the magnetic cores of the two sets of conveying tracks are synchronously cut each time through the synchronously moving cutting seats, so as to further improve the cutting efficiency.

[0008] As an optimization, the workbench is provided with a rotating first horizontal axis and a fixed second horizontal axis, one end of the first horizontal axis is connected to a driving motor, the first driving mechanism includes a first eccentric wheel fixed on the first horizontal axis and a first swing arm rotatably connected to the second horizontal axis, the first eccentric wheel and the first swing arm are arranged in close proximity, and a first connecting rod connected to the cutter seat is hinged on the first swing arm. This optimization scheme drives the first swing arm to swing forward and backward by the rotating first eccentric wheel, thereby driving the sliding of the cutter seat through the first connecting rod.

[0009] As an optimization, the first connecting rod includes a crossbar with one end hinged to the first swing arm, and an L-shaped crank arm hinged on the workbench, one end of the crank arm is hinged to the crossbar, and the other end of the crank arm is hinged to the cutter seat. In this optimization solution, the first connecting rod converts the driving force of the first driving mechanism in the front-to-back direction into the driving force in the left-to-right direction through the L-shaped crank arm, so as to realize the left-right sliding of the cutter seat.

[0010] As an optimization, the second drive mechanism includes a second eccentric wheel fixed on the first transverse axis and a second swing arm rotatably connected to the second transverse axis, the second eccentric wheel and the second swing arm are arranged in close contact, and a second connecting rod connected to the fixed seat is hinged on the second swing arm. In this optimization solution, the second drive mechanism and the first drive mechanism provide driving force by synchronously rotating the first transverse axis, saving energy.

[0011] As an optimization, the workbench is fixed with a return spring that pulls the first swing arm and the second swing arm toward the first transverse axis. This optimization solution enhances the fitting effect of the first swing arm, the second swing arm and the first transverse axis through the return spring.

[0012] As an optimization, the first swing arm and the second swing arm are both equipped with rotating rollers which are arranged in close contact with the first eccentric wheel and the second eccentric wheel. This optimization scheme reduces the wear of the first swing arm and the second swing arm and improves the durability by arranging the rollers.

[0013] As an optimization, the lengths of the crossbar and the second connecting rod can be telescopically adjusted. This optimization solution facilitates adjusting the swing angles of the first swing arm and the second swing arm by adjusting the lengths.

[0014] As an optimization, the push rod is screwed and fixed to the fixing seat. In this optimization solution, the screwed push rod can adjust the extended length, so as to facilitate the adjustment of the position of the magnetic core according to the cutting position of the slice.

[0015] As an optimization, a rotating handle is fixedly connected to the end of the first horizontal axis. This optimization solution facilitates manual rotation control of the first horizontal axis.

[0016] The beneficial effects of the utility model are:

[0017] The cores are controlled and limited by sliding ejector rods and slices, and cut one by one, thus realizing the automation of core cutting, saving labor and improving cutting efficiency.

[0018] The feeding guide is equipped with two feeding tracks. Two sets of magnetic cores transported by the two feeding tracks are cut synchronously by two synchronously moving cutters, further improving the cutting efficiency.

[0019] The first driving mechanism and the second driving mechanism move synchronously via the first transverse axis, which facilitates the control of the driving frequency of the slicer and the ejector rod and saves energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0028] like Figures 1 to 5 As shown, a magnetic core slitting device after sintering, such as Figure 1 As shown, it includes a workbench 1, a feeding guide rail 4 is provided at the front end of the workbench 1, and a receiving hole 3 is opened at the front end of the workbench 1 in this embodiment. Two conveying tracks 41 are distributed on the left and right sides of the feeding guide rail 4, and the discharge ports of the two conveying tracks 41 are both located directly above the receiving hole 3, so as to facilitate the collection of the cut and separated magnetic cores 42.

[0029] like Figure 1 As shown, the workbench 1 is provided with a cutter seat 13 that slides left and right and a fixed seat 20 that slides forward and backward. The cutter seat 13 is fixed with a slice 14 that is perpendicular to the discharge port of the feed guide rail 4. The fixed seat 20 is fixed with a push rod 21 that faces the discharge port of the feed guide rail 4. Specifically, two cutter seats 13 are provided on the workbench 1 on the left and right sides of the feed guide rail 4. The two cutter seats 13 are relatively synchronously slidable. The fixed seat 20 is fixed with two push rods 21 that face the discharge ports of the two conveyor rails respectively. The magnetic cores of the two conveyor rails are cut by two synchronously moving cutter seats to improve the cutting efficiency. The magnetic cores that slide down are supported by the push rod that faces the discharge port of the feed guide rail.

[0030] The two cutter seats 13 of this embodiment are symmetrically arranged along the feeding guide rail 4. Figure 5 As shown, the cutter seat 13 includes a rectangular slider slidably mounted on the workbench 1, and a fastening block is screwed on the front end of the rectangular slider to form a conical clamp to clamp the slice 14. A guide plate is fixedly connected to the workbench 1, and a guide rod is passed through the guide plate and fixedly connected to the rectangular slider. A tension spring 18 is fixedly connected to the guide plate to pull the rectangular slider toward the guide plate.

[0031] The push rod 21 in this embodiment is screwed and fixed to the fixing seat 20. The fixing seat 20 is a square slider. The fixing seat 20 is slidably connected to the workbench 1 through a T-slot structure. A mounting plate is fixed to the front end of the fixing seat 20. The push rod 21 is inserted into the mounting plate and screwed and fixed on both sides of the mounting plate by double nuts.

[0032] The workbench 1 is provided with a first driving mechanism and a second driving mechanism for respectively driving the cutter seat 13 and the fixed seat 20 to slide. Specifically, the workbench 1 is provided with a rotating first transverse axis 5 and a fixed second transverse axis 6, the first transverse axis 5 and the second transverse axis 6 are installed on the workbench 1 through a frame 2, one end of the first transverse axis 5 is connected to a driving motor 23, and the other end of the first transverse axis is fixedly connected to a rotating handle 22.

[0033] like Figure 3As shown, the first driving mechanism includes a first eccentric wheel 7 fixed on the first transverse axis 5 and a first swing arm 8 rotatably connected to the second transverse axis 6, the first eccentric wheel 7 and the first swing arm 8 are arranged in close proximity, a first connecting rod connected to the cutter seat 13 is hinged on the first swing arm 8, and a return spring 9 is fixed on the workbench 1 to pull the first swing arm 8 toward the first transverse axis 5.

[0034] In this embodiment, the first connecting rod includes a cross bar 11 with one end hinged to the first swing arm 8, and an L-shaped crank arm 12 hingedly rotated on the workbench 1, one end of the crank arm 12 is hinged to the cross bar 11, and the other end of the crank arm 12 is hinged to the cutter seat 13. In order to allow the crank arm 12 to have displacement when rotating, the cutter seat 13 is provided with a long slot 17 for the hinged sliding of the crank arm 12, and the end of the cross bar 11 is connected to the first swing arm 8 by a ball joint structure.

[0035] Specifically, Figure 4 As shown, the second driving mechanism includes a second eccentric wheel 15 fixed on the first transverse axis 5 and a second swing arm 16 rotatably connected to the second transverse axis 6, the second eccentric wheel 15 and the second swing arm 16 are arranged in close proximity, the second swing arm 16 is hinged with a second connecting rod 19 connected to the fixed seat 20, and the workbench 1 is fixed with a return spring 9 for pulling the second swing arm 16 toward the first transverse axis 5, the second connecting rod 19 is a long rod structure, and the two ends of the long rod are respectively hinged with the second swing arm 16 and the fixed seat 20.

[0036] The second swing arm 16 of the present embodiment is an L-shaped structure. One end of the second swing arm 16 is rotatably connected to the second horizontal axis 6, and the other end of the second swing arm 16 is arranged behind the second eccentric wheel 15. The second swing arm 16 further enhances the fitting effect with the second eccentric wheel 15 through its own gravity.

[0037] In this embodiment, the slice 14 cuts only one magnetic core 42 each time. When the second eccentric wheel 15 drives the fixing seat 20 to slide forward to the maximum distance, the lateral distance between the slice 14 and the end of the push rod 21 is the same as the width of the magnetic core 42.

[0038] In this embodiment, when the push rod 21 slides forward to the maximum distance, the moving slice 14 is cut simultaneously, and the large diameter end of the first eccentric wheel 7 and the large diameter end of the second eccentric wheel 15 are fixedly connected to the first transverse axis 5 at the same angle.

[0039] In this embodiment, the first swing arm 8 and the second swing arm 16 are both provided with a rotating roller 10 which is arranged in close contact with the first eccentric wheel 7 and the second eccentric wheel 15. By providing the roller 10, the wear of the first swing arm and the second swing arm is reduced and the durability is improved.

[0040] The lengths of the crossbar 11 and the second connecting rod 19 can be adjusted telescopically. The crossbar 11 and the second connecting rod 19 are both threaded rods, sleeves are threadedly connected at both ends of the threaded rod, and a positioning nut for adjusting the length is screwed on the threaded rod.

[0041] Working principle: When in use, the feeding guide rail 4 transports the bonded magnetic core 42 to slide onto the push rod 21, and the driving motor 23 drives the first horizontal axis 5 to rotate, driving the fixed first eccentric wheel 7 and the second eccentric wheel 15 to move synchronously. During the process of the second eccentric wheel 15 rotating from the large diameter end to the small diameter end, the return spring 9 pulls the second swing arm 16 forward, thereby driving the second connecting rod 19 to push the fixed seat 20 to slide forward, so that the push rod 21 pushes the magnetic core 42 forward to the cutting position of the slice 14.

[0042] Because the fixed angles of the large diameter end of the first eccentric wheel 7 and the large diameter end of the second eccentric wheel 15 are the same, when the second eccentric wheel 15 rotates from the large diameter to the small diameter, the first eccentric wheel 7 also rotates from the large diameter end to the small diameter end, and the reset spring 9 pulls the first swing arm 8 backward, driving the first connecting rod to drive the cutter seat 13 to slide in the direction of the feeding guide rail 4, so that the slicer 14 cuts and separates the magnetic core 42 pushed by the push rod 21.

[0043] On the contrary, when the second eccentric wheel 15 and the first eccentric wheel 7 rotate from the small diameter end to the large diameter end, the fixed seat 20 drives the push rod 21 to slide backward, and at the same time the cutter seat 13 drives the slice 14 to slide in the direction away from the feeding guide rail 4. At this time, the cut and separated magnetic core 42 lacks support and falls into the receiving hole 3 for collection, and the magnetic core at the rear continues to slide onto the push rod 21 for the next round of cutting operation, thereby realizing the automated and efficient slitting operation of the device.

[0044] Of course, the above description is not limited to the above examples. The technical features not described in the present invention can be achieved by or by adopting the existing technology, which will not be repeated here.

Ordinary technicians in this field should understand that the changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not deviate from the purpose of the present invention and should also fall within the scope of protection of the claims of the present invention.
