[0040] Reference below Figure 1 The cutting process according to the embodiment of the present invention is described.

[0041] like Figure 1 As shown, the cutting process according to the embodiment of the present invention includes the following steps:

[0042] Cutting a plurality of first through holes 100 from the first product to form a first semi-finished product;

[0043] Compounding the first semi-finished product with the second product to form a first compound product;

[0044] A plurality of second through holes 200 are cut out of the first composite product to form a second composite product, wherein the second through holes 200 are connected to the first through holes 100, the first semi-finished product forms a disconnected first sheet 300 and a first frame waste, and the second product forms a second semi-finished product with second through holes 200.

[0045] It can be understood that, first, a plurality of first through holes 100 are cut out from the first product, so that the first product forms a first semi-finished product with a plurality of first through holes 100, and then the first semi-finished product is combined with the second product to form a first composite product, and the second through hole 200 is cut out from the first composite product to form a second composite product, and the second through hole 200 is connected with the first through hole 100, so that the first semi-finished product is formed into two separate parts: the first sheet 300 and the first frame, and the second product forms a second semi-finished product with the second through hole 200, that is, the second composite product. The combined product includes a second semi-finished product and a first sheet 300 and a first frame waste located on the second semi-finished product. This can ensure that the first sheet 300 is cut out of the first product, and can also ensure that the second semi-finished product only has the second through hole 200, so that the second semi-finished product can still carry the first sheet 300, and the first sheet 300 will not fall off the second semi-finished product; therefore, the cutting process of the present application can make multiple sheets located on the second product at the same time, so as to facilitate the subsequent combination of multiple sheets with other composite products, improve processing efficiency and reduce costs.

[0046] The first product is a strip-shaped product or a coil, which can be used as a cut raw material for a plurality of first sheets 300 ; the second product is also a strip-shaped product or a coil.

[0047] Specifically, cutting can be processing methods such as die cutting and punching, and in different steps, cutting can even refer to different specific cutting methods.

[0048] It is understandable that the second product is the first support film;

[0049] The step of cutting a plurality of second through holes 200 from the first composite product comprises the following steps:

[0050] During cutting, the cutting tool first cuts through the second product in the first composite product, and then cuts through the first semi-finished product in the first composite product.

[0051] For example, in this embodiment, since the second product is the first support film, and since the material of the support film is relatively soft, when cutting the second through hole 200, the tool first passes through the first semi-finished product and then cuts the first support film. In the process of cutting the first semi-finished product, the first support film at the bottom may be offset, and the first semi-finished product is prone to flashing, resulting in poor cutting; therefore, when cutting the first composite product, the tool first passes through the first support film and then the first semi-finished product, which can improve the appearance after cutting, improve cutting accuracy and product yield. Specifically, the second product in the first composite product is placed on top and the first semi-finished product is placed on the bottom, and the tool cuts through the second product and the first semi-finished product from top to bottom.

[0052] It is understandable that the first product includes steel, and the steel is located on one side of the first composite product, and the first sheet material 300 includes a steel sheet. For example, in this embodiment, especially when the first product is a product with a relatively high hardness such as steel, the steel is located at the bottom and the first bottom film is located at the top, so that when cutting the second through hole 200, the cutter first cuts through the first bottom film and then cuts through the steel, thereby improving the product accuracy and yield of the steel sheet formed by cutting the steel to form the first sheet material 300.

[0053] It can be understood that the number of the second through holes 200, the first through holes 100 and the first sheet 300 corresponds to each other. For example, in one embodiment, the number of the second through holes 200, the first through holes 100 and the first sheet 300 can correspond to each other. For example, the first through holes 100 are half of the annular track, and the second through holes 200 are the other half of the annular track. In this way, the first through holes 100 and the second through holes 200 together constitute the annular track, and the first sheet 300 is formed inside the annular track. After the second through holes 200 are cut out, the first semi-finished product is formed into two separated parts, the first sheet 300 located inside the annular track and the first frame waste located outside the annular track.

[0054] In this embodiment, if Figure 1 As shown, the first through holes 100 are the four corners of the circular track, the second through holes 200 are the four sides of the circular track, and the first through holes 100 and the second through holes 200 together constitute the circular track.

[0055] It can be understood that the first product further includes a second bottom film covering one side of the steel material, and the first bottom film in the first composite product is located on the side of the first semi-finished product with the second bottom film;

[0056] The step of cutting a plurality of first through holes 100 from the first product further includes the following steps:

[0057] While cutting out the first through hole 100, a first positioning hole is cut out at the edge of the first product in the width direction;

[0058] The step of cutting a plurality of second through holes 200 from the first composite product further includes the following steps:

[0059] By aligning the first positioning hole, cutting out the second through hole 200;

[0060] Among them, the width of the first supporting film is smaller than that of the second supporting film, so that the first positioning hole can expose both sides of the first supporting film. After cutting out the second through hole 200, the steel material forms a steel sheet and a third frame waste, and the second supporting film forms a second sheet and a second frame waste. The first positioning hole is located on the third frame waste and the second frame waste.

[0061] For example, in this embodiment, by compounding the second bottom film on one side of the steel material, the first through hole 100 is cut out on the first product while the first positioning hole is cut out, so that when the second through hole 200 is cut out, the first positioning hole can be aligned to achieve the alignment cutting of the second through hole 200, so as to achieve the position correspondence and communication between the first through hole 100 and the second through hole 200. In this way, the second product compounded on the first semi-finished product cannot cover the first positioning hole, and the second product is needed, that is, the width of the first bottom film is required to be It is smaller than the second supporting film so that the first positioning hole of the second supporting film can expose both sides of the first supporting film, thereby performing hole die cutting; in addition, in order to ensure the cutting accuracy of the steel sheet, when the first semi-finished product composed of the steel material and the second supporting film is compounded with the first supporting film, the first supporting film is compounded on one side of the second supporting film, so as to facilitate cutting of the second through hole 200. The first composite product is the first supporting film, the second supporting film and the first semi-finished product from top to bottom, thereby avoiding the first semi-finished product, that is, the steel sheet, from having a burr, thereby improving the cutting yield.

[0062] It is understandable that the following steps are also included:

[0063] draining the third frame waste in the second composite product to form a third composite product;

[0064] The fourth composite product is composited to the side of the third composite product where the steel sheet is exposed, so as to form a fifth composite product.

[0065] For example, in this embodiment, the steel sheet formed after cutting the steel material is separated from the third frame waste, so that the third frame waste needs to be discharged, and the fourth composite product is composited on the side where the steel sheet is exposed, thereby forming the fifth composite product. The fifth composite product includes the fourth composite product, the steel sheet, the second supporting film and the first supporting film.

[0066] It can be understood that the width of the fourth composite product is smaller than that of the second bottom film, so that the first positioning hole on the second frame waste can expose both sides of the fourth composite product;

[0067] The following steps are also included:

[0068] registering the first positioning hole of the fifth composite product, and cutting a second positioning hole for the fourth composite product on the fifth composite product;

[0069] After the first supporting film is discharged to take away the second supporting film, a sixth composite product is formed;

[0070] Compounding the seventh composite product with the side of the sixth composite product that exposes the steel sheet to form an eighth composite product; wherein the width of the seventh composite product is smaller than that of the fourth composite product, so that the second positioning hole can expose both sides of the seventh composite product;

[0071] The eighth composite product is die-cut by aligning the second positioning hole to obtain a finished product; wherein the finished product includes a steel sheet and a first sheet material and a second sheet material respectively located on both sides of the steel sheet, the first sheet material and the second sheet material have the same shape and size, and their areas are both larger than the steel sheet.

[0072] For example, in this embodiment, since the fifth composite product includes a second bottom film with a first positioning hole, when cutting the second positioning hole of the fourth composite product on the fifth composite product, the first positioning hole can be aligned to cut the second positioning hole, so that the relative position of the second positioning hole and the steel sheet is fixed. After cutting the second positioning hole, the first bottom film can be removed together with the second bottom film, and then the seventh composite product is composited on the side of the sixth composite product where the steel sheet is exposed, so as to form the eighth composite product. The eighth composite product is die-cut by aligning the second positioning hole to finally obtain a finished product, which includes a steel sheet and a first sheet 300 and a second sheet located on both sides of the steel sheet, respectively. The first sheet 300 and the second sheet have the same shape and size, and are both larger than the size of the steel sheet. In order to die-cut the seventh composite product and the fourth composite product in the eighth composite product, the seventh composite product must not cover the second positioning hole, that is, the width of the seventh composite product is smaller than that of the fourth composite product. In the final product obtained in this way, there are no knife marks on the fourth composite product and the seventh composite product, and the appearance of the steel sheet is excellent and the flash is less.

[0073] It is understandable that the following steps are also included:

[0074] Compounding a third supporting film on any one of the two surfaces of the eighth composite product to form a ninth composite product; wherein the width of the third supporting film is smaller than that of the fourth composite product, so that the second positioning hole can expose both sides of the third supporting film;

[0075] Die-cut the eighth composite product on the ninth composite product by registering the second positioning hole, so that the eighth composite product is formed into a finished product and a fourth frame waste;

[0076] The fourth frame waste is discharged to obtain the third base film and the finished product located on the third base film.

[0077] For example, in this embodiment, the third base film is firstly laminated on one of the two sides of the eighth composite product, and then the eighth composite product is cut so that the cut finished product can fall on the third base film, so that a plurality of finished products can be stored by rolling up the third base film.

[0078] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
