Description

Technical Field

[0001] The utility model relates to a silicon steel sheet feeding machine. Background Art

[0002] Silicon steel sheet is a kind of carbon steel thin plate containing a certain amount of silicon, mainly used for making various motors, generators, transformers, reactors, voltage transformers, current transformers, etc. In the existing industrial practice, silicon steel coils are usually made into silicon steel coils with different heights, an inner diameter of 508 mm and an outer diameter of 1200 mm by a large slitting machine. However, except for some advanced / complex fully automatic core winding equipment that can directly use this kind of silicon steel coil, it is often necessary to first adopt the manual feeding method of workers to further prepare small silicon steel coils that can be used by the winding machine. For example, the semi-automatic core winding machine in the existing industrial applications can only use silicon strip coils with different heights, an inner diameter of 70 mm and an outer diameter of 400 mm. The existing manual feeding not only consumes a large amount of physical strength and has low efficiency, but also has certain safety hazards due to the relatively thin silicon steel sheets. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a silicon steel sheet feeding machine, which has a simple structure, is suitable for the semi-automatic feeding operation requirements, helps to reduce the labor intensity and improve the safety of the operation.

[0004] The technical solution of the utility model is: a silicon steel sheet feeding machine, which is provided with a frame, on which there is an operation platform and a winding assembly (a component for winding steel strip / silicon steel strip) is rotationally connected (for example, installed through bearings), and a winding motor for driving the winding assembly is installed. The winding assembly is vertically arranged and extends upward from the operation platform. The winding assembly includes an outer ring body and an inner ring body that are inserted into each other, and a conical surface (a frustum of a cone with a larger upper part and a smaller lower part) is arranged between the inner ring body and the outer ring body (the so-called conical surface is the surface that fits together after being inserted in place).

[0005] Preferably, the outer side surfaces on the front and rear sides of the inner ring body and the outer side surfaces on the front and rear sides of the outer ring body are conformable to each other, and both are in the shape of a frustum of a cone (a frustum of a cone with a larger upper part and a smaller lower part).

[0006] Preferably, the outer side surfaces on the left and right sides of the inner ring body and the outer side surfaces on the left and right sides of the outer ring body are conformable to each other, and both are in the shape of a vertical plane or an inclined plane with the lower end inward.

[0007] Furthermore, vertical slide rails (slide rails extending vertically in the plane where they are located) are provided on the outer side surfaces of the left and right sides of the inner ring body, and vertical sliding grooves (sliding grooves extending vertically in the plane where they are located) that are matched with the slide rails on the same side of the inner ring body (slide rails located on the same vertical plane or inclined plane) are respectively provided on the inner side surfaces of the left and right sides of the outer ring body. When the inner ring body is inserted into the outer ring body, the vertical slide rails on the left and right sides of the inner ring body are respectively inserted into the vertical sliding grooves on the left and right sides of the outer ring body, so that the inner ring body can drive the outer ring body to rotate together.

[0008] Preferably, the outer ring body is formed by the mating of two symmetrically arranged outer half-ring bodies (or semi-outer ring bodies).

[0009] Preferably, the vertical sliding groove is a dovetail groove (a trapezoid with a smaller top and a larger bottom in cross-section), and the vertical slide rail conforms to the vertical sliding groove. Thus, after the inner ring body and each outer half-ring body are mutually clamped (plugged) in place through the vertical sliding groove and the slide rail, due to the cooperation of the vertical slide rail and the vertical sliding groove, the outer half-ring bodies cannot move outward, fixing the two outer half-ring bodies on the inner ring body to form a whole.

[0010] Preferably, a vertically (extending in the up and down direction of the plane where it is located) through (a through groove extending vertically to both ends) card slot (a narrow groove / slit for clamping the edge of the silicon steel sheet) is provided on the circumferential surface (outer side surface) of the outer ring body.

[0011] The number of the card slots can be one, and when necessary, it can also be two, which are provided at the front end and / or the rear end of the outer ring body (the front end or the rear end of the left and right middle planes of the outer ring body). When there are two card slots, any one of them can be selected during use for convenient operation.

[0012] Preferably, stepped notches are provided at the front side and / or the rear side edge parts of the mating surface (the surface mating with another outer half-ring body, and after the two outer half-ring bodies are mated, the mating surface is located on the left and right middle planes of the outer ring body) of the outer half-ring body, and the card slot is formed by the mating of the stepped notches on the same side of the two outer half-ring bodies.

[0013] Furthermore, the outer shape of the outer ring body should generally be cylindrical to meet the winding requirements of the silicon steel coil, and a suitable one can be selected according to actual needs.

[0014] Preferably, a lifting ring is threadedly connected to the inner ring body.

[0015] For example, the driving shaft hole of the inner ring body can be set as a through hole, and internal threads for connecting the lifting ring can be provided at the top of the driving shaft hole or a lifting ring nut for connecting the lifting ring can be embedded to achieve the threaded connection between the inner ring body and the lifting ring.

[0016] Preferably, the aperture of the part with internal threads at the top of the drive shaft hole can be smaller than the aperture of the remaining part of the drive shaft hole (the part sleeving the extension of the drive shaft) to adapt to the lifting rings under common specifications.

[0017] The driving connection between the winding motor and the inner ring body can be achieved in any suitable manner. A drive shaft hole can be provided on the inner ring body. The drive shaft hole is a central through hole extending vertically. The output shaft (shaft extension) of the winding motor is inserted into the drive shaft hole and fixedly connected to the drive shaft hole (inner ring body) on the inner ring body. The driving connection between the drive shaft extension and the drive shaft hole (inner ring body) can be realized by means of key connection. For example, flat key connection or spline connection.

[0018] The present utility model can be used in the following way: Lift a silicon steel coil (silicon steel strip coil) with an outer diameter of 1200 mm and an inner diameter of 508 mm onto the workbench of the silicon steel sheet uncoiler. Pull the inner ring silicon steel sheets into the winding assembly by 10 mm. Set the uncoiling time on the counter of the control box. Turn the toggle switch to the automatic position. Start the motor and begin automatic winding. The timer starts timing. When the set time is reached, it stops automatically. Pull the lifting ring upwards by hand and pull out the inner ring body, then the wound small silicon steel coil can be taken down. Press the reset button to enter the initial state for working again.

[0019] The present utility model can realize the automatic winding of the steel strip coil with the cooperation of workers. It can prepare a silicon steel coil (such as a silicon steel strip coil with different heights and an inner diameter of 70 mm and an outer diameter of 400 mm) suitable for a semi-automatic iron core winding machine by using a large silicon steel coil under a certain specification (for example, a silicon steel coil with different heights and an inner diameter of 508 mm and an outer diameter of 1200 mm). It can be used to replace the manual feeding in the prior art. Moreover, it has a simple structure, is convenient to use, requires less manual operation, and has a low labor intensity. It not only significantly improves the production efficiency, but also helps to avoid / prevent the possible harm to the operators during the manual winding process. Description of the Drawings

[0032] Refer to Figures 1 to 12 , the winding assembly (or called wedge-shaped material receiving device) of this uncoiler is used for winding the silicon steel strip. The starting edge of the silicon steel strip is inserted (clamped) into the card slot 49 and fixed, and then the winding assembly is driven to rotate by the driving motor 20 to realize the winding of the silicon steel strip, and the silicon steel strip is wound on the winding assembly to form a silicon steel coil 51 with the required specifications (dimensions).

[0033] The existing finished large silicon steel coil 50 (for example, inner diameter 508 mm, outer diameter 1200 mm) is placed on the working platform 11 and surrounds the outside of the winding assembly. When necessary, a bracket for restricting / fixing the large silicon steel coil can be set on the working platform, for example, a circular ring frame surrounding the outside of the large silicon steel coil. Since the silicon steel strip is wound from the inside of the large silicon steel coil during winding, the frame arranged outside the large silicon steel coil will not interfere with the operation.

[0034] The inner ring body 30 adopts an integrated structure, and a vertically extending drive shaft hole 36 is set in the middle, which is connected to the drive shaft of the drive motor inserted into the drive shaft hole through a key. The outer surfaces 34 on the front and rear sides of the inner ring body are frustum surfaces (curved surfaces similar to the side of a truncated cone), and the taper β of the corresponding truncated cone can be about 6° (specifically can be set according to actual needs). The outer surfaces on the left and right sides of the inner ring body are planes, which can be vertical planes (planes parallel to the axis of the inner ring body) or inclined planes with the lower end facing inward, and the inclination angle (angle relative to the axis of the inner ring body) can also be about 6° (specifically can be set according to actual needs). Through this cone / bevel design with a larger top and a smaller bottom, not only the vertical positioning of the inner ring body on the outer ring body is achieved, but also the automatic centering of the inner ring body on the outer ring body is achieved, and the operation is also convenient.

[0035] The planes on the left and right sides of the inner ring body are provided with slide rails (protrusion-shaped structures used to cooperate with the slide grooves on the outer ring body) 35 extending up and down along the plane. The slide rails can be of equal width up and down, or wide at the top and narrow at the bottom. Dovetail-shaped slide rails that conform to the dovetail grooves (sliding fit) can be used. After the dovetail-shaped slide rails are inserted into the dovetail grooves on the inner wall of the corresponding side of the outer ring body, the inner and outer ring bodies can only move up and down relative to each other by relying on the groove-rail cooperation.

[0036] The outer ring body 40 is composed of two independent parts (which can be called outer semi-ring body / semi-outer ring body) 41 and 42 which are symmetrically arranged on the left and right sides, and the two parts are matched to form a complete outer ring body. The inner surface 44 on the front and rear sides of each outer semi-ring body adopts a truncated cone shape (inverted truncated cone shape) that conforms to the outer surface of the corresponding part of the inner ring body, and the left inner surface (the outer semi-ring body located on the left) or the right inner surface (the outer semi-ring body located on the right) adopts a plane (vertical plane or inclined plane) that conforms to the outer surface of the corresponding part of the inner ring body, and is provided with a slide groove 45 that cooperates with the slide rail on the corresponding side of the inner ring body. After the inner ring body is plugged into place on the outer ring body, the outer surface of each side (front and back, left and right) of the inner ring body and the inner surface of each side (front and back, left and right) of the outer ring body fit each other, and the slide rails on the left and right sides of the inner ring body are inserted into the slide grooves on the left and right sides of the outer ring body, and fit each other with the lateral side and / or longitudinal side of the corresponding slide groove. Based on operational needs / convenience, a certain matching clearance / difference can be set between partially mating surfaces and / or in terms of the taper of the frustum, so as to facilitate the insertion and removal of the inner ring body on the outer ring body.

[0037] A small step (step-shaped notch) 48 is processed on the front and / or rear edge of the outer half ring body mating surface. When the two half ring bodies are mated, the gap formed by the corresponding step is used as a slot.

[0038] The size of the card slot can be set according to actual needs, for example, the width is 0.5 mm, the depth is 10 mm, and the height is the same as the winding component (vertically penetrating the outer ring body).

[0039] The drive motor can be a reduction motor (a motor equipped with a speed reducer), which is installed on the frame 10 below the working platform. The output shaft extension 22 of the drive motor faces vertically upward and is inserted into the drive shaft hole 36 of the inner ring body. When a flat key connection is adopted, corresponding key grooves 37 are provided on the inner wall of the drive shaft hole and the drive shaft extension, and the flat key 23 is installed in the corresponding key grooves.

[0040] The drive shaft hole on the inner ring body is set as a through hole penetrating up and down. A lifting ring nut (for example, an M12 nut) is installed at the top of the through hole for threaded connection with the lifting ring 18. Alternatively, the top of the through hole can be set as a reduced diameter section (reducing the inner diameter), and internal threads are provided in the reduced diameter section 39 for threaded connection with the lifting ring. During assembly, first install the lifting ring (threaded connection) on the inner ring body, install the two outer half ring bodies on the inner ring body, and move the inner ring body or the winding assembly formed by the combination of the inner and outer ring bodies through manual or mechanical hoisting using the lifting ring, so that the drive shaft extension of the drive motor is assembled with the drive shaft hole on the inner ring body. The key grooves on the drive shaft extension and the drive shaft hole are aligned to form a hole for passing through the flat key. The hole for passing through the flat key penetrates upward through the drive shaft extension and the inner ring body (the key grooves on the drive shaft extension and the drive shaft hole can be set according to this requirement), and the flat key is inserted in place through the hole opening (the hole opening formed by the hole for passing through the flat key passing through the inner ring body) 38 on the top surface of the inner ring body. During disassembly, the inner ring body is pulled out upward through the lifting ring, and the two outer half ring bodies are taken out, thereby realizing the separation of the small silicon steel coil (the wound silicon steel coil) from the unwinding machine.

[0041] The controller 13 of the drive motor and other related devices (if any) can be configured according to the existing technology. The controller is installed at a certain height on the frame for convenient use. Various required buttons / keys, display screens, indicator lights, etc. can be set on the controller. Since the operation / winding control of the drive motor can adopt any suitable existing technology, the controller can be flexibly configured according to actual needs. For example, a control switch for the drive motor is equipped.

[0042] The front, rear, left, right and other orientation descriptions used in this specification are only for explaining the relative direction / position relationship of relevant parts, and do not constitute a limitation on the actual use orientation.

[0043] All the preferred and optional technical means disclosed in the present invention can be arbitrarily combined to form several different specific implementation manners, unless otherwise specified and when one preferred or optional technical means is a further limitation of another technical means.
