Description

Technical Field

[0001] The utility model relates to a magnetic core production device, in particular to a stringing machine in the production and manufacturing of magnetic cores, belonging to the field of mechanical technology. Background Art

[0002] In the production of magnetic cores, during the annealing process, the magnetic cores are strung on a tooling and then hoisted into an annealing furnace for annealing. The tooling has a fixed (circular) bottom plate, and multiple core rods are circularly distributed on the bottom plate (the core rods can be inserted into the holes on the bottom plate). The magnetic cores are strung on the core rods in series. After the stringing is completed, a lifting tool is connected and installed on the tooling, and then it is hoisted into the annealing furnace. After sealing, annealing is carried out, and then it is hoisted out and sent to the next process. Currently, loading the magnetic cores onto the core shafts before annealing is carried out manually. Since the production of magnetic cores is a large-batch operation, this method requires a lot of labor and high labor costs. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above problems existing in the current magnetic core stringing, and provide a magnetic core stringing machine.

[0004] To achieve the purpose of the utility model, the following technical solution is adopted: a magnetic core stringing machine includes a magnetic core sorting and sequencing device. The rear end of the magnetic core sorting and sequencing device has a magnetic core sequencing channel. A horizontal conveying disk is connected to the rear end of the magnetic core sequencing channel. The conveying disk is connected with a rotation driving mechanism. A plurality of notches are evenly distributed on the edge of the conveying disk. The conveying disk is located on a support platform. A limiting ring is fixedly arranged on the outer circumference of the conveying disk. When the conveying disk rotates, each notch part corresponds to the outlet of the magnetic core sequencing channel in turn. A blanking hole is opened on the support platform. The blanking hole is located on a circle with the same center as the notch. A cam divider is installed below the rear of the support platform. A chassis is fixedly connected to the output shaft of the cam divider. A plurality of sleeves are fixedly connected in a circular distribution on the chassis. A limiting piece is fixedly connected near the lower end of the core rod. After the lower end of the core rod is inserted into the sleeve, the limiting piece is limited at the mouth of the sleeve. In the top view direction, the center of the blanking hole is located on the circle formed by the plurality of sleeves.

[0005] Further, a vertical lifting module is fixedly installed beside the cam divider. A clamping jaw cylinder is fixedly connected to the lifting end of the lifting module.

[0006] Further, the number of the notches is 8.

[0011] To more fully explain the implementation of the present utility model, implementation examples of the present utility model are provided. These implementation examples are only elaborations of the present utility model and do not limit the scope of the present utility model.

[0012] The present utility model will be further explained in detail with reference to the accompanying drawings. The reference numerals in the drawings are: 1: magnetic core sorting device; 2: support table; 3: rotating motor; 4: conveying disk; 5: cam divider; 6: chassis; 7: sleeve; 8: core rod; 9: limiting piece; 10: lifting module; 11: clamping jaw cylinder; 12: blanking hole; 13: magnetic core sorting channel; 14: notch.

[0013] As shown in the attached drawings, a magnetic core threading machine includes a magnetic core sorting device, which is an existing technology developed by the applicant. The technical solution disclosed in Chinese Patent CN 220986290U (a magnetic core sorting device) is adopted. The rear end of the magnetic core sorting device has a magnetic core sorting channel 13. A horizontal conveying tray 4 is connected to the rear end of the magnetic core sorting channel 13. The conveying tray 4 is connected with a rotation driving mechanism. In this embodiment, the conveying tray is fixedly connected to the output shaft of a rotating motor 3, and the rotating motor is fixedly installed on a support table 2. A plurality of notches 14 are evenly distributed on the edge of the conveying tray. In this embodiment, the number of the notches is 8. The conveying tray is located on the support table 2. A limiting ring 15 is fixedly arranged on the conveying tray in the circumferential upward direction. When the conveying tray rotates, each notch part corresponds to the outlet of the magnetic core sorting channel in turn. A blanking hole 12 is opened on the support table. The blanking hole 12 is located on a circle with the same center as the notch. When the conveying tray rotates, the notches pass over the blanking hole in turn. The size of the blanking hole is larger than that of the magnetic core. When the conveying tray rotates, the magnetic core carried in the notch falls through the blanking hole. A cam divider 5 is installed at the rear lower part of the support table. A chassis 6 is fixedly connected to the output shaft of the cam divider. A plurality of sleeves 7 are fixedly connected to the chassis 6 in a circular distribution. A limiting piece 9 is fixedly connected to the lower end of a core rod 8. After the lower end of the core rod is inserted into the sleeve, the limiting piece is limited at the mouth of the sleeve. In the top view direction, the center of the blanking hole is located on the circle formed by the plurality of sleeves. An up-and-down lifting module 10 is fixedly installed beside the cam divider. The lifting end of the lifting module 10 is fixedly connected with a clamping jaw cylinder 11. The lifting module can adopt a ball screw driven by a motor. When the clamping jaws of the clamping jaw cylinder are closed, they enclose the core rod. The magnetic core threaded onto the core rod can fall onto the clamping jaws. When the clamping jaws of the clamping jaw cylinder are separated, the magnetic core can fall between the clamping jaws. The first magnetic core threaded onto the core rod falls onto the clamping jaws. After the magnetic cores fall through the blanking hole and are threaded onto the core rod in turn, the magnetic cores are supported by the clamping jaws, which can prevent the disconnection of the welding part caused by the large drop of the initial magnetic core. In the present utility model, the rotating motor, the cam divider, the lifting module, the clamping jaw cylinder and the magnetic core sorting device are all connected to a controller for control.

[0014] The working process of the present utility model is as follows: Insert the core rod into the sleeve, control the rotation of the cam divider to make the core rod rotate to the position below the blanking hole. After the magnetic core sorting and arranging device sorts the magnetic cores, they flow out from the magnetic core sorting channel. The conveying disk rotates. When the notch is communicated with the magnetic core sorting channel, the magnetic cores enter the notch and rotate with the conveying disk. When it rotates to the blanking hole, the magnetic cores fall from the blanking hole and pass through the core rod. The clamping jaws are closed and located above to support the first magnetic core inserted onto the core rod. The subsequent magnetic cores are sequentially inserted onto the core rod. The lifting module continuously descends during the material insertion process. After the clamping jaws move close to the limit piece, the clamping jaws open, and the magnetic cores fall onto the limit piece. After the height of the magnetic cores on one core rod meets the requirements, control the rotation of the cam divider to rotate the core rod filled with magnetic cores out, and at the same time, the empty core rod rotates into the position below the blanking hole. After taking out the core rod filled with magnetic cores, insert the empty core rod into the sleeve.

[0015] After the embodiments of the present utility model are described in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model all belong to the scope of the technical solution of the present utility model, and the present utility model is not limited to the implementation manners of the examples given in the specification.
