Description

Technical Field

[0001] The utility model belongs to the technical field of transformer manufacturing equipment, and specifically relates to a single-hole material sorting mechanism for silicon steel sheets. Background Art

[0002] At present, most of the equipment for producing transformer cores in the electrical industry uses belt conveyors to convey silicon steel sheets, and the belt conveyors also have the function of fixed-point blanking. In order to speed up the blanking speed of silicon steel sheets, cylinder punching is usually used. However, for the material sorting mode of downward needle positioning, the cylinder punching is easy to interfere with the positioning needle. If the cylinder punching is not used, and only relying on the free fall of the sheet, due to the effect of atmospheric pressure, the efficiency of silicon steel sheet blanking will be very low, which will seriously affect the overall efficiency of the equipment. The existing pre-stacking platform was originally positioned by two positioning pins, and two holes needed to be punched in the sheet. The more holes there are, the greater the iron loss of the core. See the Chinese patent named "A pre-stacking platform for transformer core shearing and stacking equipment", which discloses that the pre-stacking platform was originally positioned by two positioning pins, and two holes needed to be punched in the sheet, resulting in large iron loss of the core.

[0027] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0028] Example 1:

[0029] As Figures 1 - 3 shown, a single-hole sorting mechanism for silicon steel sheets includes a sorting belt conveyor and a pre-stacking platform. The sorting belt conveyor is located above the pre-stacking platform. The sorting belt conveyor includes 2 belts 1 arranged in parallel. The pre-stacking platform includes a first pre-stacking platform 3, a first pre-stacking rack 4, a second pre-stacking platform 5, and a second pre-stacking rack 6. The first pre-stacking platform 3 is connected above the first pre-stacking rack 4, and the second pre-stacking platform 5 is connected above the second pre-stacking rack 6. Ball screw mechanisms are arranged on both the first pre-stacking rack 4 and the second pre-stacking rack 6. A plurality of material pushing cylinders 2 are arranged between the 2 belts 1. A moving sleeve 7 is connected to the ball screw mechanism. A positioning pin 8 is vertically connected to the moving sleeve 7. Holes 9 are provided on both the first pre-stacking platform 3 and the second pre-stacking platform 5. The upper end of the positioning pin 8 extends out of the hole 9. Side positioning mechanisms 10 are arranged on both the first pre-stacking platform 3 and the second pre-stacking platform 5. The side positioning mechanisms 10 and the holes 9 are distributed at intervals left and right.

[0030] Specifically, the material arranging belt conveyor is an existing belt conveyor, and its specific structure and working principle will not be described in detail here. The two belts 1 are driven by a driving roller and a secondary driving roller. The belt 1 is used to transport sheet materials. A plurality of material striking cylinders 2 are arranged between the two belts 1. By striking the sheet materials on the belt 1 with the material striking cylinders 2, the blanking speed of the sheet materials 12 is effectively increased, and the production efficiency is improved.

[0031] For the specific structure of the pre-stack platform, refer to the patent named "A Pre-stack Platform for a Transformer Core Shearing and Stacking Device". The present utility model is an improvement on the technical solution of this patent. By reducing the two positioning pins 8 to one positioning pin 8, only one hole needs to be punched on the sheet material to achieve automatic material arrangement, reducing the iron loss. At the same time, when the material striking cylinder 2 strikes the material, compared with the two positioning pins 8, the setting of one positioning pin 8 reduces the probability of the sheet material touching the positioning pin 8 when falling under the premise of not affecting the production efficiency. The falling multiple sheet materials are arranged and patted neatly by the side positioning mechanism 10, which is convenient for grasping.

[0032] Embodiment 2:

[0033] Based on Embodiment 1, the plurality of material striking cylinders 2 are evenly spaced.

[0034] Specifically, the even spacing makes the material striking cylinders 2 strike the material evenly.

[0035] Preferably, none of the plurality of material striking cylinders 2 is directly above the positioning pin 8.

[0036] Specifically, that is, the material striking cylinders 2 avoid the positioning pin 8, preventing the sheet material from touching the positioning pin 8 when falling, solving the problem that the material striking cylinder is prone to interference with the positioning pin during material striking. Only slight modification to the original material arranging belt conveyor is required, with a simple structure, being economical and practical.

[0037] Preferably, as Figure 4 and Figure 5 shown, the side positioning mechanism 10 includes a linear guide rail 10-1, a servo motor 10-2, a left-right screw 10-3, and two side guide blocks 10-4. Two side guide blocks 10-4 are connected in parallel and spaced on the linear guide rail 10-1, and the servo motor 10-2 is connected to the two side guide blocks 10-4 through the left-right screw 10-3.

[0038] Specifically, the left - right screw rod 10 - 3 is controlled by the servo motor 10 - 2 to drive the side guide blocks 10 - 4 to move on the linear guide rail 10 - 1, and the distance between the two side guide blocks 10 - 4 is controlled. According to the width of the sheet material, the distance between the two side guide blocks 10 - 4 is adjusted, so that multiple sheets of material between the two side guide blocks 10 - 4 are neatly arranged. Among them, the linear guide rail 10 - 1, the servo motor 10 - 2 and the left - right screw rod 10 - 3 are located below the material receiving plate, and the side guide blocks 10 - 4 are located above the material receiving plate. The structure is simple, the degree of automation is high, and it is easy to operate.

[0039] Preferably, the shape of the side guide block 10 - 4 is plate - shaped, the plate - shape is vertically arranged and the upper part of the plate - shape is inclined outward.

[0040] Specifically, the upper part of the plate - shape being inclined outward increases the distance between the two side guide blocks 10 - 4, which is conducive to the sheet material falling between the two side guide blocks 10 - 4. The inclined setting enables the assembled materials falling on the side guide blocks 10 - 4 to slide along the inclined plate, and the structure is simple.

[0041] Preferably, the distance between the two side guide blocks 10 - 4 is greater than or equal to the width of the sheet material.

[0042] Specifically, this setting facilitates the sheet material falling between the two side guide blocks 10 - 4.

[0043] Preferably, the number of the material - pushing cylinders 2 is 5 or 7.

[0044] Specifically, the number of 5 or 7 improves the production efficiency, and is economical and practical.

[0045] Preferably, as Figure 6 shown, the material - pushing cylinder 2 includes a cylinder 2 - 1, a mounting plate 2 - 2 and a material - pushing head 2 - 3. The power output end of the cylinder 2 - 1 is connected to the material - pushing head 2 - 3, and the outside of the cylinder 2 - 1 is connected to the body of the material - arranging belt conveyor through the mounting plate 2 - 2.

[0046] Specifically, it is convenient to connect the material - pushing cylinder 2 to the body of the material - arranging belt conveyor through the mounting plate 2 - 2, and the cylinder 2 - 1 controls the material - pushing head 2 - 3 to strike the sheet material on the belt. The structure is simple.

[0047] Preferably, the material - pushing head 2 - 3 is made of polyurethane material.

[0048] Specifically, the material - pushing head 2 - 3 made of polyurethane material will not damage the sheet material.

[0049] The positioning of the sheet material in this utility model is realized through two methods, specifically:

[0050] Method 1: After the sheet material is demagnetized, the feeding cylinder 2 knocks down the sheet material on the belt 1. When the sheet material descends, the servo motor 10-2 controls the left and right screw rod 10-3 to drive the side guide block 10-4 to move on the linear guide rail 10-1, so that the distance between the two side guide blocks 10-4 is the same as the width of the sheet material, and multiple falling sheet materials can be sorted out; the positioning pin 8 positions the sorted sheet material.

[0051] Method 2: After the sheet material is demagnetized, the feeding cylinder 2 knocks down the sheet material on the belt 1. When the sheet material descends, the servo motor 10-2 controls the left and right screw rod 10-3 to drive the side guide block 10-4 to move on the linear guide rail 10-1, so that the distance between the two side guide blocks 10-4 is greater than the width of the sheet material. After a stepping-level sheet material completely falls onto the receiving drawer 11, then the multiple sheet materials between the two side guide blocks 10-4 are sorted out by the two side guide blocks 10-4; the positioning pin 8 positions the sorted sheet material.

[0052] In the description of the present utility model, it should be understood that if there are terms such as "left", "outer", "right", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation to the present utility model.

[0053] The above examples are only illustrative of the present utility model and do not constitute a limitation to the protection scope of the present utility model. Any design identical or similar to the present utility model falls within the protection scope of the present utility model.
