Description

Technical Field

[0001] The present invention belongs to the field of silicon steel sheet forming. Background Art

[0002] As Figure 1 shown, a common high-voltage transformer core 1 is assembled by stacking a number of silicon steel sheets. The two ends of the strip-shaped silicon steel sheet with the largest area are pointed silicon steel sheets 2 with angled tips. The pointed silicon steel sheet 2 is cut from a silicon steel strip. In order to prevent rust, the surface of the silicon steel strip has been treated with rust prevention before cutting, such as oil film treatment, etc. However, after the silicon steel strip is cut into the pointed silicon steel sheet 2 with angled tips at both ends, the pointed edges of the pointed silicon steel sheet 2 are newly cut and have no attached oil film, and are completely exposed to the air, so there is a risk of rust during long-term storage;

[0003] Generally, after the cutting process, it is necessary to immediately stack and assemble into a transformer core, and then perform rust prevention treatment on the periphery of the core. Therefore, after the cutting process, the core stacking must be carried out immediately. Otherwise, there is a risk of rust on the pointed edges of the cut pointed silicon steel sheets 2, which restricts the flexibility of the core processing process. The purpose of this solution is to enable the pointed edges of the processed pointed silicon steel sheets 2 to have the ability of rust prevention and long-term storage. Summary of the Invention

[0011] A second concave curved surface adapted to the second tip curved surface is provided on the side of the second fixed seat close to the second shearing tip. The second tip curved surface is in sliding fit with the second concave curved surface, and the axes of the curved surfaces of the second tip curved surface and the second concave curved surface both coincide with the axis of the tipping plate rotating shaft.

[0012] Further, the front end of the tipping plate shearing channel penetrates through the waist of the first tip curved surface, so that a folded angular tip-shaped first shearing bite is formed at the waist of the first tip curved surface. In a top view, the contour of the folded angular tip-shaped first shearing bite is consistent with the contour of the first angular tip;

[0013] The rear end of the tipping plate shearing channel penetrates through the waist of the second tip curved surface, so that a folded angular tip-shaped second shearing bite is formed at the waist of the second tip curved surface.

[0015] A gantry is provided above the middle of the tipping plate. The two ends of the gantry are fixed on the cross beam; a front telescopic device extending forward and a rear telescopic device extending backward are respectively installed on the front and rear sides of the gantry;

[0016] The end of the telescopic part of the front telescopic device is fixed with a first driving wheel support seat. A first driving wheel is rotatably installed on the first driving wheel support seat. The first driving wheel is tangent to the first driving inclined surface.;

[0017] At the end of the telescopic part of the rear telescoper, a second driving wheel support is fixed. A second driving wheel is rotatably installed on the second driving wheel support, and the second driving wheel is tangent to the second driving inclined plane.

[0018] Furthermore, a first hard folding strip in the shape of an angle tip is movably arranged on the upper side of the first fixing seat. One end of the first hard folding strip is fixedly connected to the first driving wheel support through a first linkage arm. A first folded-line-shaped oil storage sponge is fixedly arranged along the inner side contour of the first hard folding strip, and an anti-rust oil or anti-rust grease is stored in the first folded-line-shaped oil storage sponge; the first folded-line-shaped oil storage sponge is consistent with the first angle tip contour.

When the second shearing bite moves upward to just be higher than the second fixing seat, the second folded-line-shaped oil storage sponge just moves forward to adhere to the second tip curved surface, so that the second folded-line-shaped oil storage sponge just adheres to the second shearing bite along the contour, and then transfers the anti-rust oil on the second folded-line-shaped oil storage sponge to the second shearing bite along the contour.

[0022] Beneficial effects: The pointed edges of the pointed silicon steel sheets processed by the present invention have the ability of rust prevention and long-term storage;

[0023] Taking the pointed contour of the first included angle as an example, during the process of the first shearing point quickly tilting upwards, the first driving wheel adaptively moves backwards under the push of the first driving inclined surface, so that the first driving wheel support, the first linkage arm, the first rigid folding strip and the first folded-line-shaped oil storage sponge gradually move backwards synchronously; during the process of the first shearing tip end of the shearing swing plate making an upward tilting movement, after the first shearing bite cuts off the silicon steel strip to be sheared, it continues to move upwards. When the first shearing bite moves upwards to just be higher than the first fixed seat, the first folded-line-shaped oil storage sponge just moves backwards to adhere to the first pointed curved surface, so that the first folded-line-shaped oil storage sponge just adheres to the first shearing bite along the contour, and then part of the rust preventive oil on the first folded-line-shaped oil storage sponge is transferred along the contour to the pointed contour of the first included angle of the pointed silicon steel sheet in the first shearing bite, thereby realizing oiling and rust prevention for the pointed contour of the first included angle of the newly formed pointed silicon steel sheet.

[0037] The front end of the rocker shear channel 6 penetrates through the waist of the first pointed curved surface 10a, so that the waist of the first pointed curved surface 10a forms a folded-angle pointed first shear bite 6a. In a top-down view, the contour of the folded-angle pointed first shear bite 6a is consistent with the first included-angle pointed contour 3a.

[0038] The rear end of the rocker shear channel 6 penetrates through the waist of the second pointed curved surface 10b, so that the waist of the second pointed curved surface 10b forms a folded-angle pointed second shear bite 6b. In a top-down view, the contour of the folded-angle pointed second shear bite 6b is consistent with the second included-angle pointed contour 3b.

[0045] Under the adaptive telescoping of the front telescoper 17a, the first driving wheel 16a is always tangent to the first driving inclined surface 5.1a. When the first shearing tip 5a end of the shearing seesaw 4 makes an upward movement, the first driving wheel 16a adaptively moves backward under the push of the first driving inclined surface 5.1a of the upward movement, so that the first driving wheel support 18a, the first linkage arm 19a, the first rigid folding strip 20a and the first folded-line-shaped oil storage sponge 21a gradually move backward synchronously; during the process that the first shearing tip 5a end of the shearing seesaw 4 makes an upward movement, the first shearing bite 6a moves upward accordingly.

[0046] Under the adaptive telescoping of the rear telescoper 17b, the second driving wheel 16b is always tangent to the second driving inclined surface 5.1b.

When the second shearing bite 6b moves upward to just be higher than the second fixing seat 15b, the second folded-line-shaped oil storage sponge 21b just moves forward to adhere to the second pointed head curved surface 10b, so that the second folded-line-shaped oil storage sponge 21b just adheres to the second shearing bite 6b along the contour, and further transfers the antirust oil on the second folded-line-shaped oil storage sponge 21b to the second shearing bite 6b along the contour.

[0047] Working principle part:

[0048] Forming process of a piece of pointed silicon steel sheet 2:

[0049] Step 1, in the initial state, under the rigid constraints of the first driving wheel 16a and the second driving wheel 16b, the shearing seesaw 4 is in a horizontal state, and the first shearing bite 6a and the second shearing bite 6b at both ends of the seesaw shearing channel 6 are respectively aligned and communicated with the first silicon steel sheet fixed shearing channel 7a and the second silicon steel sheet fixed shearing channel 7b;

[0050] Step 2: The silicon steel strip conveying device 25 conveys the silicon steel strip 6 to be sheared forward in a horizontal straight line direction until the silicon steel strip 6 to be sheared passes through the second silicon steel sheet fixed shearing channel 7b, the rocker shearing channel 6, and the first silicon steel sheet fixed shearing channel 7a in sequence along the length direction.

[0051] Step 2: Control the rear expander 17b to quickly extend backward actively, so that the second driving wheel 16b quickly pushes the second driving inclined surface 5.1b. At the same time, the front expander 17a makes an adaptive movement, so that the first driving wheel 16a is always tangent to the first driving inclined surface 5.1a, so that the second shearing tip 5b at the rear end of the shearing rocker 4 quickly tilts downward, and the first shearing tip 5a at the front end quickly tilts upward; so that the first shearing bite 6a moves upward and bites off the shearing silicon steel strip 6 at the first shearing bite 6a along the contour. At the same time, the second shearing bite 6b moves downward and bites off the shearing silicon steel strip 6 at the second shearing bite 6b along the contour, so that a newly formed pointed silicon steel sheet 2 is formed in the rocker shearing channel 6. The first included angle pointed contour 3a and the second included angle pointed contour 3b at the front and rear ends of the pointed silicon steel sheet 2 coincide in the first shearing bite 6a and the second shearing bite 6b respectively. At the same time, a section of silicon steel sheet waste is formed in the first silicon steel sheet fixed shearing channel 7a, and the new end of the silicon steel strip 6 to be sheared is in the second silicon steel sheet fixed shearing channel 7b and waits for the next shearing.

[0052] In the above process, during the process of the first shearing tip 5a quickly tilting upward, the first driving wheel 16a adaptively moves backward under the push of the first driving inclined surface 5.1a, so that the first driving wheel support 18a, the first linkage arm 19a, the first rigid folding strip 20a, and the first folded line-shaped oil storage sponge 21a gradually move backward synchronously; during the process of the first shearing tip 5a end of the shearing rocker 4 making an upward tilting movement, the first shearing bite 6a continues to move upward after biting off the silicon steel strip 6 to be sheared. When the first shearing bite 6a moves upward to just be higher than the first fixed seat 15a, the first folded line-shaped oil storage sponge 21a just moves backward to adhere to the first pointed surface 10a, so that the first folded line-shaped oil storage sponge 21a just adheres to the first shearing bite 6a along the contour, and then transfers part of the anti-rust oil on the first folded line-shaped oil storage sponge 21a to the first included angle pointed contour 3a of the pointed silicon steel sheet 2 in the first shearing bite 6a along the contour, so as to realize oiling and rust prevention for the first included angle pointed contour 3a of the newly formed pointed silicon steel sheet 2.

[0053] Step 3: Control the front expander 17a to quickly and actively extend forward, so that the first driving wheel 16a quickly pushes the first driving inclined plane 5.1a. At the same time, the rear expander 17b makes an adaptive movement, so that the second driving wheel 16b is always tangent to the second driving inclined plane 5.1b, so that the second shearing tip 5b at the rear end of the shearing seesaw 4 quickly tilts up, and the first shearing tip 5a at the front end quickly tilts down; during the process of the second shearing tip 5b of the shearing seesaw 4 tilting up, the second driving wheel 16b adaptively moves forward under the push of the second driving inclined plane 5.1b, so that the second driving wheel support 18b, the second linkage arm 19b, the second rigid folding strip 20b and the second folded-line-shaped oil storage sponge 21b gradually move forward synchronously; during the process of the second shearing tip 5b of the shearing seesaw 4 tilting up, the second shearing bite 6b moves up accordingly. When the second shearing bite 6b moves up to just be higher than the second fixed seat 15b, the second folded-line-shaped oil storage sponge 21b just moves forward to adhere to the second tip curved surface 10b, so that the second folded-line-shaped oil storage sponge 21b just adheres to the second shearing bite 6b along the contour, and then transfers part of the antirust oil on the second folded-line-shaped oil storage sponge 21b to the second included-angle tip contour 3b of the pointed silicon steel sheet 2 in the second shearing bite 6b along the contour, so as to achieve oiling and rust prevention for the second included-angle tip contour 3a of the newly formed pointed silicon steel sheet 2.

[0054] Step 4: By controlling the front expander 17a and the rear expander 17b, make the shearing seesaw 4 return to the horizontal state under the rigid constraint of the first driving wheel 16a and the second driving wheel 16b; then the silicon steel strip conveying device 25 conveys the silicon steel strip 6 to be sheared with its end in the second silicon steel sheet fixed shearing channel 7b forward along a horizontal straight line direction until the end of the silicon steel strip 6 to be sheared sequentially passes through the seesaw shearing channel 6 and the first silicon steel sheet fixed shearing channel 7a along the length direction. During the process of the silicon steel strip 6 to be sheared sequentially passing through the seesaw shearing channel 6 and the first silicon steel sheet fixed shearing channel 7a, the formed pointed silicon steel sheet 2 left in the seesaw shearing channel 6 and the silicon steel sheet waste in the first silicon steel sheet fixed shearing channel 7a in the previous step are pushed forward by the way. Thus, return to "Step 2" to execute the forming of the next pointed silicon steel sheet 2.

[0055] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
