Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and in particular to a cutting device for producing high magnetic induction and low iron loss oriented silicon steel. Background Technology

[0002] Because silicon steel sheets have high magnetic permeability and low iron loss, they are mainly used to process iron cores inside motors. For iron cores with complex geometries, CNC plasma cutting machines are usually used to process silicon steel sheets. The specific steps are as follows: the silicon steel sheet is placed on the support frame of the cutting machine, the cutting path is set by computer programming, and the cutting gun cuts the silicon steel sheet according to the set path. After the silicon steel sheet is cut, an iron core, an outer frame scrap, and an inner frame scrap are produced. The inner frame scrap can usually be cut again to process iron cores with smaller shapes and sizes.

[0003] When using plasma cutting of silicon steel sheets, support cones are typically used to hold the object in place. The support cones are spaced far apart to catch the molten slag and sparks ejected during the cutting process. However, the molten slag and sparks can splash and solidify on the top of the support cones. The top of the support cone with the molten slag and sparks will be higher than the other support cones, causing the tops of several support cones to no longer maintain a flat surface. The silicon steel sheet placed on the support cones will also not maintain a horizontal position, affecting the cutting effect. Since the support cones are all independent of each other, existing technologies generally require manual processing of non-standard support cones, which is inefficient.

[0004] In summary, this application proposes a cutting device for producing high magnetic induction and low iron loss oriented silicon steel, thereby improving the aforementioned technical problems. Summary of the Invention

[0005] To overcome the shortcomings of existing plasma cutting silicon steel sheets, such as inconsistent height of the support cones caused by molten slag sputtering, which affects the horizontal placement and cutting effect of silicon steel sheets, and the need for manual handling of each support cone, resulting in low efficiency, this invention provides a cutting device for the production of high magnetic induction and low iron loss oriented silicon steel.

[0006] Technical Solution: A cutting device for producing high-magnetic-induction, low-iron-loss grain-oriented silicon steel includes a fixed platform, a three-axis moving frame, and a cutting gun. The three-axis moving frame is mounted on the fixed platform. The cutting gun is connected to the three-axis moving frame. The device also includes a first sleeve, a second sleeve, a third sleeve, and a fourth sleeve. The first, second, third, and fourth sleeves are slidably connected to the fixed platform. Each of the first, second, third, and fourth sleeves has a built-in electric push rod, which extends and retracts to achieve lifting and lowering. The second sleeve is slidably sleeved on the outside of the first sleeve. The third sleeve is slidably sleeved on the outside of the second sleeve. The fourth sleeve is slidably sleeved on the outside of the third sleeve. The first, second, third, and fourth sleeves together support the silicon steel sheet.

[0007] Furthermore, it is particularly preferred that the cutting device for producing high magnetic induction and low iron loss oriented silicon steel also includes a first driving component and a push plate; the first driving component is installed on a fixed platform; and the first driving component is connected to a push plate for cleaning molten slag.

[0008] In addition, it is particularly preferred that the push plate is made of carbon tool steel with high hardness and good wear resistance.

[0009] Furthermore, it is particularly preferred that the bottom of the push plate be made smooth.

[0010] Furthermore, it is particularly preferred that the above-mentioned cutting device for producing high magnetic induction and low iron loss grain-oriented silicon steel also includes a collecting ring groove, a second driving member, and an annular baffle; the collecting ring groove is fixedly connected to the bottom of the fixed platform; the collecting ring groove is located outside the fourth sleeve; a protrusion is provided on the outside of the fourth sleeve; the second driving member is fixedly connected to the collecting ring groove; an annular baffle for forming a cooling pool is fixedly connected to the telescopic end of the second driving member; the annular baffle is slidably connected to the protrusion on the outside of the fourth sleeve; and a water inlet is provided on the annular baffle.

[0011] Furthermore, it is particularly preferred that the contact surfaces between any two adjacent sleeves in the first sleeve, second sleeve, third sleeve, and fourth sleeve are provided with rubber sealing rings.

[0012] Furthermore, it is particularly preferred that the bottom of the annular baffle is provided as a conical surface.

[0013] Furthermore, it is particularly preferred that the upper side of the push plate is set as an inclined surface.

[0014] Furthermore, it is particularly preferred that the diameter of the collecting annular groove is set larger than the diameter of the annular baffle.

[0015] Furthermore, it is particularly preferred that the surfaces of the first sleeve, the second sleeve, the third sleeve, the fourth sleeve, and the annular baffle are all covered with a galvanized anti-rust coating.

[0016] Beneficial effects:

[0017] The silicon steel sheet is supported sequentially by the first, second, third, and fourth sleeves, allowing the molten slag and sparks generated during cutting to cool and solidify naturally during their fall. This largely prevents the molten slag and sparks from solidifying on the sleeve surface, significantly reducing the workload of subsequent sleeve surface cleaning. The sleeve surface is then cleaned by scraping with a push plate, which is faster. Furthermore, areas on the sleeve surface without molten slag and sparks can act as supports to hold the push plate, ensuring stable movement and improving the removal effect of the push plate.

[0018] A temporary water storage tank is formed by the annular baffle, the first sleeve, the second sleeve, the third sleeve, and the fourth sleeve. Water is injected into the annular baffle through the water inlet to form a cooling pool. The molten slag sparks that are not completely cooled by the air are cooled by the water stored in the cooling pool. The cooling water has a buffering effect, which can buffer the molten slag sparks and prevent them from contacting the sleeves below the water surface, further eliminating the possibility of molten slag sparks adhering to the surface of the sleeves.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0028] Example 1: Refer to Figures 1-7 As shown, a cutting device for producing high magnetic induction and low iron loss oriented silicon steel includes a fixed platform 1, a three-axis moving frame 2, and a cutting gun 3; the three-axis moving frame 2 is mounted on the fixed platform 1; the cutting gun 3 is connected to the three-axis moving frame 2; the three-axis moving frame 2 drives the cutting gun 3 to move up and down, left and back, and forward and backward; silicon steel sheets 7 are placed on the fixed platform 1; the cutting gun 3 cuts the silicon steel sheets 7 into a first iron core 8 and a second iron core 9;

[0029] It also includes a first sleeve 4, a second sleeve 5, a third sleeve 6, and a fourth sleeve 10; the first sleeve 4, the second sleeve 5, the third sleeve 6, and the fourth sleeve 10 are slidably connected on the fixed platform 1 respectively; each of the first sleeve 4, the second sleeve 5, the third sleeve 6, and the fourth sleeve 10 has an electric push rod built in it, and the electric push rod can be extended and retracted to achieve lifting and moving; the second sleeve 5 is slidably sleeved on the outside of the first sleeve 4; the third sleeve 6 is slidably sleeved on the outside of the second sleeve 5; the fourth sleeve 10 is slidably sleeved on the outside of the third sleeve 6; the first sleeve 4, the second sleeve 5, the third sleeve 6, and the fourth sleeve 10 together support the silicon steel sheet 7.

[0030] It also includes a first driving component 201 and a push plate 202; the first driving component 201 is installed in the middle of the fixed platform 1, and the first driving component 201 consists of two symmetrically arranged electric sliders; the first driving component 201 is connected to the push plate 202; the push plate 202 is moved left and right by the first driving component 201.

[0031] The push plate 202 is made of carbon tool steel with high hardness and good wear resistance.

[0032] Furthermore, to reduce the friction between the push plate 202 and the sleeve, the bottom of the push plate 202 is made smooth.

[0033] The following is a detailed description of the cutting process for silicon steel sheet 7:

[0034] First, the staff fixes the front and rear edges of the silicon steel sheet 7 using the clamps on the fixed platform 1. At this time, the center of the silicon steel sheet 7 is aligned with the center of the first sleeve 4 to ensure that the silicon steel sheet 7 will not be horizontally displaced during cutting. Then, the staff sets the cutting path through programming, thus completing the preparation work before cutting.

[0035] Then, the silicon steel sheet 7 is cut, and the specific steps are as follows: The three-axis moving frame 2 is controlled to move the cutting gun 3 downwards towards the upper surface of the silicon steel sheet 7. The electric push rod inside the first sleeve 4 moves the first sleeve 4 upwards to press against the center of the silicon steel sheet 7, while the other sleeves remain retracted and do not contact the silicon steel sheet 7. Then, the cutting gun 3 is driven to cut the silicon steel sheet 7 according to the set cutting path. Figure 2 and Figure 4 As shown, the second waste material 9003 is cut out along the second inner edge 9002. The diameter of the first sleeve 4 is smaller than the diameter of the central circular area of ​​the second waste material 9003. Therefore, the first sleeve 4, in conjunction with the clamping plate on the fixed platform 1, can provide stable support for the silicon steel sheet 7, preventing the second waste material 9003 from falling directly to the ground. The resulting molten slag and sparks will not splash onto the surface of the first sleeve 4, but will fall directly. This allows the molten slag and sparks to naturally cool and solidify into granules during the fall, impacting the surfaces of other sleeves as hard particles, and then splashing into the large waste collection container at the bottom of the fixed platform 1. After cutting, the second waste material 9003, completely separated from the silicon steel sheet 7, will be supported by the first sleeve 4. Then, the first sleeve 4 will rise further, pushing the second waste material 9003 above the silicon steel sheet 7, as shown in the figure. Figure 5 As shown, it is easy for people to pick it up manually with tools.

[0036] Then, the first sleeve 4 moves down to the supporting height, and the second sleeve 5 raises the support column to the center position of the second iron core 9, again preventing the second outer edge 9001 from overlapping with the surface of the second sleeve 5. Then, along the second outer edge 9001, the second iron core 9 is cut and separated from the silicon steel sheet 7. During this process, similar to the second waste 9003, because the second outer edge 9001 does not overlap with the surface of the second sleeve 5, the downward-spraying molten slag and sparks will not splash onto the surface of the second sleeve 5. The molten slag and sparks will naturally cool into granules during the fall and splash into the large waste collection container at the bottom of the fixed platform 1. After the cutting is completed, the second iron core 9, which is completely separated from the silicon steel sheet 7, is also lifted by the second sleeve 5, and its state is as follows. Figure 6 As shown, it is then manually removed using tools.

[0037] Then, following the same procedure described above, the first waste material 8003 is cut and separated from the silicon steel sheet 7 along the first inner edge 8002. Finally, the first iron core 8 is cut and separated from the silicon steel sheet 7 along the first outer edge 8001. Similarly, the third sleeve 6 and the fourth sleeve 10 play the same role in the cutting process. Therefore, the entire silicon steel sheet 7 is cut from the middle to the outer edge, and finally divided into the second waste material 9003, the second iron core 9, and the first iron core 8. In the above method, the long-distance fall of the molten slag sparks allows them to cool and solidify naturally during the fall, which can basically avoid the molten slag sparks solidifying on the sleeve surface and greatly reduce the workload of cleaning the sleeve surface afterward.

[0038] After a whole piece of silicon steel sheet 7 is cut and consumed, the first sleeve 4 is controlled to move downwards so that its upper surface is aligned with the lower surface of the push plate 202. At the same time, the second sleeve 5, the third sleeve 6, and the fourth sleeve 10 are controlled to move downwards to be flush with the first sleeve 4, as shown in the figure. Figure 7 As shown, the first driving component 201 then moves the push plate 202 to the left, causing the push plate 202 to scrape against the upper surfaces of the first sleeve 4, the second sleeve 5, the third sleeve 6, and the fourth sleeve 10 until the push plate 202 moves to the left side of the fourth sleeve 10. This allows the molten slag falling on all sleeve surfaces to be scraped away, preventing the slag from affecting the flatness of the sleeve surfaces and ensuring the cutting quality of the subsequent silicon steel sheet 7. It should be noted that the push plate 202 is made of carbon tool steel, which has good hardness and wear resistance, thus ensuring… The push plate 202 will not be damaged when removing molten slag. By making the surface of the push plate 202 smooth, the friction between the push plate 202 and the sleeve is reduced, the resistance of the push plate 202 moving on the sleeve surface is increased, and the push plate 202 can fit the sleeve surface more closely. This method of forming a whole platform and then cleaning with the push plate 202 is faster. Moreover, the area without molten slag and sparks can be used as a support to hold the push plate 202, so that the push plate 202 can move stably and improve the removal effect of the push plate 202.

[0039] Example 2: Based on Example 1, such as Figures 5-7 As shown, it also includes a collection ring groove 301, a second driving member 302, and an annular baffle 303; the collection ring groove 301 is fixedly connected to the bottom of the fixed platform 1; the collection ring groove 301 is located outside the fourth sleeve 10; a protrusion 1001 is provided on the outside of the fourth sleeve 10; the second driving member 302 is fixedly connected to the collection ring groove 301, and the second driving member 302 is an electric push rod; an annular baffle 303 is fixedly connected to the telescopic end of the second driving member 302; the annular baffle 303 is slidably connected to the protrusion 1001 on the outside of the fourth sleeve 10; a water inlet is provided on the annular baffle 303, and the water inlet is connected to an external water supply device through a pipe.

[0040] Rubber sealing rings are provided on the contact surfaces between adjacent sleeves in the first sleeve 4, the second sleeve 5, the third sleeve 6, and the fourth sleeve 10.

[0041] Furthermore, to prevent water and slag from accumulating at the bottom of the annular baffle 303, the bottom of the annular baffle 303 is set as a conical surface 30301.

[0042] The upper side of the push plate 202 is set as an inclined surface 20201.

[0043] The diameter of the collecting annular groove 301 is set to be larger than the diameter of the annular baffle 303.

[0044] Furthermore, to prevent the first sleeve 4, second sleeve 5, third sleeve 6, fourth sleeve 10 and annular baffle 303 from rusting due to prolonged contact with water, the surfaces of the first sleeve 4, second sleeve 5, third sleeve 6, fourth sleeve 10 and annular baffle 303 are all coated with a galvanized anti-rust coating.

[0045] To further eliminate the possibility of molten slag and sparks adhering to the sleeve surface, a liquid cooling backup can be added to the existing air cooling system. Specifically, at the start of machining, the sidewall of the annular baffle 303 should be positioned higher than the highest point of the fourth sleeve 10, as shown in the image. Figure 5As shown, at this time, a temporary water storage tank is formed by the annular baffle 303, the first sleeve 4, the second sleeve 5, the third sleeve 6, and the fourth sleeve 10. Water is injected into the annular baffle 303 through the water inlet to form a cooling pool. The molten slag sparks that are not completely cooled by the air are cooled by the water stored in the cooling pool. The cooling water also has a buffering effect, which can buffer the molten slag sparks and prevent them from contacting the sleeves below the water surface. It should be noted that the rubber seal on the contact surface between two adjacent sleeves prevents water from flowing out from the contact surface. To prevent leakage from gaps and improve the sealing of the temporary water storage tank, after the silicon steel sheet 7 is cut, all the sleeves are lowered to be flush with the lower surface of the push plate 202, and the second drive component 302 is controlled to drive the annular baffle 303 to move downward, so that the uppermost side of the annular baffle 303 is lower than the upper surface of all the sleeves. Then, following the same steps as in Example 1, the push plate 202 is made to scrape against the sleeves. During this process, the water and slag on the surface of the sleeves flow to the bottom of the annular baffle 303 and pass through the push plate 202. The water and slag remaining on the surface of the sleeve are scraped off. It is explained that the upper side of the push plate 202 is designed with an inclined surface 20201 to facilitate water flow downwards along the inclined surface 20201, preventing water accumulation on the upper side of the push plate 202. Then, the annular baffle 303 is controlled to continue moving downwards, causing the annular baffle 303 to disengage from the protrusion 1001 on the outer side of the fourth sleeve 10, thereby creating an annular gap between the annular baffle 303 and the fourth sleeve 10. This allows water and slag in the temporary water storage tank to flow through the annular gap to... The water is discharged into the collection ring trough 301 to clean the temporary outlet trough. It is explained that by setting the bottom of the annular baffle 303 as a conical surface 30301, the water and slag at the bottom of the annular baffle 303 can flow downward along the conical surface 30301, avoiding the accumulation of water and slag at the bottom of the annular baffle 303. Furthermore, the galvanized coating on the surfaces of the first sleeve 4, the second sleeve 5, the third sleeve 6, the fourth sleeve 10, and the annular baffle 303 prevents moisture from corroding their surfaces and improves their service life.

[0046] Note that by setting the diameter of the collecting ring groove 301 to be larger than the diameter of the annular baffle 303, it is easier for the collecting ring groove 301 to collect the molten slag sparks that are splashed in all directions, thus preventing the molten slag sparks from falling directly to the ground and reducing subsequent cleaning work.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
