Description

Technical Field

[0001] This application relates to the field of die-cut product technology, and in particular to a cutting process. Background Technology

[0002] In related technologies, the final product required by the client includes steel sheets and sheet material located on at least one side of the steel sheets, with the sheet material size being larger than the steel sheet size. The steel sheets are formed by punching steel coils. The conventional processing method is to process the steel sheets and sheet material separately, and then combine the individual steel sheets with the sheet material. However, this processing method is not only labor-intensive but also inefficient. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a cutting process that allows multiple sheets to be simultaneously placed on a second product, facilitating the subsequent lamination of multiple sheets with other composite products, thereby improving processing efficiency and reducing costs.

[0004] According to an embodiment of the present invention, the cutting process includes the following steps: cutting a plurality of first through holes into a first product to form a first semi-finished product; combining the first semi-finished product with a second product to form a first composite product; cutting a plurality of second through holes into the first composite product to form a second composite product; wherein the second through holes are connected to the first through holes, the first semi-finished product forms a disconnected first sheet and a first frame waste, and the second product forms a second semi-finished product with second through holes.

[0005] The cutting process according to embodiments of the present invention has at least the following beneficial effects: First, a plurality of first through holes are cut into a first product, thereby forming a first semi-finished product with a plurality of first through holes. Then, the first semi-finished product and the second product are combined to form a first composite product. Second through holes are cut into the first composite product to form a second composite product. The second through holes are connected to the first through holes, thereby forming two separate parts in the first semi-finished product: a first sheet and a first frame waste. The second product forms a second semi-finished product with second through holes. That is, the second composite product includes the second semi-finished product and the first sheet and the first frame waste located on the second semi-finished product. This ensures that the first sheet is cut from the first product and that the second semi-finished product only has the second through holes, so that the second semi-finished product can still support the first sheet and prevent the first sheet from falling off the second semi-finished product. Therefore, the cutting process of this application can allow multiple sheets to be located on the second product at the same time, and also facilitates the subsequent combination of multiple sheets with other composite products, thereby improving processing efficiency and reducing costs.

[0006] According to some embodiments of the present invention, the second product is a first backing film;

[0007] The step of cutting several second through holes in the first composite material includes the following steps:

[0008] During cutting, the cutting tool first cuts through the second product in the first composite, and then cuts through the first semi-finished product in the first composite.

[0009] According to some embodiments of the present invention, the first product includes steel, and the steel is located on one side of the first composite, and the first sheet includes a steel sheet.

[0010] According to some embodiments of the present invention, the number of the second through hole, the first through hole, and the first sheet are in a one-to-one correspondence.

[0011] According to some embodiments of the present invention, the first product further includes a second backing film covering one side of the steel material, and the first backing film in the first composite is located on the side of the first semi-finished product with the second backing film;

[0012] The step of cutting multiple first through holes in the first product also includes the following steps:

[0013] While cutting out the first through hole, cut out the first positioning hole on the edge of the first product width direction;

[0014] The step of cutting several second through holes in the first composite material also includes the following steps:

[0015] The second through hole is cut out by aligning it with the first positioning hole;

[0016] The width of the first support film is smaller than that of the second support film, so that the first positioning hole can be exposed on both sides of the first support film. After the second through hole is cut out, the steel material is formed into a steel sheet and a third frame waste. The second support film is formed into a second sheet and a second frame waste. The first positioning hole is located on the third frame waste and the second frame waste.

[0017] According to some embodiments of the present invention, the following steps are also included:

[0018] Remove the waste from the third frame in the second composite to form the third composite;

[0019] A fourth composite is applied to the side of the third composite that exposes the steel sheet, in order to form a fifth composite.

[0020] According to some embodiments of the present invention, the width of the fourth composite is smaller than that of the second support film, so that the first positioning hole on the second frame waste can expose both sides of the fourth composite;

[0021] It also includes the following steps:

[0022] Align the first positioning hole of the fifth composite with the second positioning hole of the fourth composite on the fifth composite;

[0023] After the first support film is removed to remove the second support film, the sixth composite product is formed;

[0024] The side of the sixth composite exposed by the steel sheet is laminated with the seventh composite to form the eighth composite; wherein the width of the seventh composite is smaller than that of the fourth composite, so that the second positioning hole can be exposed on both sides of the seventh composite.

[0025] By aligning the second positioning hole, the eighth composite product is die-cut to obtain the finished product; wherein, the finished product includes a steel sheet and a first piece and a second piece located on both sides of the steel sheet, the first piece and the second piece have the same shape and size, and their areas are both larger than the steel sheet.

[0026] According to some embodiments of the present invention, the following steps are also included:

[0027] A third backing film is laminated to either side of the eighth composite to form a ninth composite; wherein the width of the third backing film is smaller than that of the fourth composite, so that the second positioning hole can be exposed on both sides of the third backing film.

[0028] By aligning the second positioning hole, the eighth composite on the ninth composite is die-cut so that the eighth composite has a finished product and a fourth frame waste.

[0029] After removing the waste from the fourth frame, the third support film and the finished product located on the third support film are obtained.

[0030] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Furthermore, the specific features, structures, products, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0040] The following is for reference. Figure 1 The cutting process of an embodiment of the present invention is described.

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

[0042] Multiple first through holes 100 are cut into the first product to form the first semi-finished product;

[0043] The first semi-finished product is combined with the second product to form the first composite product;

[0044] A number of second through holes 200 are cut into the first composite to form a second composite; 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] Understandably, multiple first through holes 100 are first cut into the first product, thus forming a first semi-finished product with multiple first through holes 100. Then, the first semi-finished product and the second product are combined to form a first composite product. Second through holes 200 are cut into the first composite product, thus forming a second composite product. The second through holes 200 are connected to the first through holes 100, thereby forming two separate parts: a first sheet 300 and a first frame waste. The second product forms a second semi-finished product with the second through holes 200, i.e., the second composite product. The composite 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 ensures that the first sheet 300 can be cut from the first product, while also ensuring that the second semi-finished product only has a second through hole 200. This allows the second semi-finished product to still support the first sheet 300, preventing the first sheet 300 from falling off. Therefore, the cutting process of this application allows multiple sheets to be located on the second product simultaneously, facilitating the subsequent lamination of multiple sheets with other composite products, improving processing efficiency and reducing costs.

[0046] The first product is a strip or roll, which can be used as a cutting material for multiple first sheets 300; the second product is also a strip or roll.

[0047] Specifically, cutting can refer to processing methods such as die-cutting and punching. 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 out several second through holes 200 in the first composite material includes the following steps:

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

[0051] For example, in this embodiment, since the second product is the first support film, and the support film is made of a relatively soft material, if the cutter passes through the first semi-finished product before cutting the second through hole 200, the first support film located at the bottom may shift during the cutting process of the first semi-finished product. This can easily cause burrs on the first semi-finished product, resulting in poor cutting. Therefore, when cutting the first composite product, having the cutter pass through the first support film before the first semi-finished product can improve the appearance after cutting, increase cutting accuracy, and improve product yield. Specifically, the second product in the first composite product is positioned on top, and the first semi-finished product is positioned below, with the cutter cutting through the second product and the first semi-finished product sequentially from top to bottom.

[0052] It is understood that the first product includes steel, and the steel is located on one side of the first composite product, and the first sheet 300 includes a steel sheet. For example, in this embodiment, especially when the first product is a product with high hardness such as steel, the steel is placed below and the first support film is placed above, so that when cutting the second through hole 200, the tool first cuts through the first support film and then cuts through the steel, thereby improving the product accuracy and yield of the steel sheet formed by cutting the steel into the first sheet 300.

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

[0054] In this embodiment, as Figure 1 As shown, the first through hole 100 is the four corners of the circular track, and the second through hole 200 is the four sides of the circular track. The first through hole 100 and the second through hole 200 together constitute the circular track.

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

[0056] The step of cutting multiple first through holes 100 into the first product also includes the following steps:

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

[0058] The step of cutting out several second through holes 200 in the first composite material also includes the following steps:

[0059] The second through hole 200 is cut out by aligning it with the first positioning hole;

[0060] The width of the first support film is smaller than that of the second support film, so that the first positioning hole can be exposed on both sides of the first support film. After the second through hole 200 is cut out, the steel material is formed into a steel sheet and a third frame waste, the second support film is formed into a second sheet and a second frame waste, and the first positioning hole is located on the third frame waste and the second frame waste.

[0061] For example, in this embodiment, by laminating a second backing film onto one side of the steel material, the first through hole 100 is cut into the first product simultaneously with the first positioning hole. This allows the first positioning hole to be aligned with the second through hole 200 during cutting, ensuring that the first through hole 100 and the second through hole 200 are positioned and connected. Consequently, the second product laminated onto the first semi-finished product cannot obstruct the first positioning hole. Therefore, the width of the second product, i.e., the first backing film, needs to be... The first support film is smaller than the second support film so that the first positioning hole of the second support film can be exposed on both sides of the first support film, thus enabling die cutting. In addition, in order to ensure the cutting accuracy of the steel sheet, when the first semi-finished product composed of steel and the second support film is combined with the first support film, the first support film is combined on one side of the second support film, so as to facilitate the cutting of the second through hole 200. The first composite product consists of the first support film, the second support film and the first semi-finished product from top to bottom, thus avoiding burrs on the first semi-finished product, i.e., the steel sheet, and improving the cutting yield.

[0062] Understandably, this also includes the following steps:

[0063] Remove the waste from the third frame in the second composite to form the third composite;

[0064] A fourth composite is applied to the side of the third composite that exposes the steel sheet, in order to form a fifth composite.

[0065] For example, in this embodiment, the steel sheet formed after the steel is cut is separated from the third frame waste, so the third frame waste needs to be discharged, and a fourth composite is laminated to the side of the exposed steel sheet to form a fifth composite. The fifth composite includes the fourth composite, the steel sheet, the second support film, and the first support film.

[0066] Understandably, the width of the fourth composite is smaller than that of the second backing film so that the first positioning hole on the second frame can be exposed on both sides of the fourth composite.

[0067] It also includes the following steps:

[0068] Align the first positioning hole of the fifth composite with the second positioning hole of the fourth composite on the fifth composite;

[0069] After the first support film is removed to remove the second support film, the sixth composite product is formed;

[0070] The side of the sixth composite exposed by the steel sheet is laminated with the seventh composite to form the eighth composite; wherein the width of the seventh composite is smaller than that of the fourth composite, so that the second positioning hole can be exposed on both sides of the seventh composite.

[0071] By aligning the second positioning hole, the eighth composite product is die-cut to obtain the finished product; wherein, the finished product includes a steel sheet and a first piece and a second piece located on both sides of the steel sheet, the first piece and the second piece 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 includes a second support film with a first positioning hole, when cutting the second positioning hole on the fourth composite on the fifth composite, the second positioning hole can be cut by aligning it with the first positioning hole, thus ensuring that the relative position of the second positioning hole and the steel sheet is fixed. After cutting the second positioning hole, the first support film along with the second support film can be removed. Then, the seventh composite is laminated on the side of the sixth composite that exposes the steel sheet, thereby forming the eighth composite. By aligning the second positioning hole and die-cutting the eighth composite, the final product is obtained. The finished product includes a steel sheet and a first sheet 300 and a second sheet located on both sides of the steel sheet. The first sheet 300 and the second sheet have the same shape and size, and both are larger than the steel sheet size. In order to die-cut the seventh composite and the fourth composite in the eighth composite, the seventh composite must not block the second positioning hole, that is, the width of the seventh composite is smaller than that of the fourth composite. In the final product obtained in this way, there are no tool marks on the fourth composite and the seventh composite, and the steel sheet has a good appearance with few burrs.

[0073] Understandably, this also includes the following steps:

[0074] A third backing film is laminated to either side of the eighth composite to form a ninth composite; wherein the width of the third backing film is smaller than that of the fourth composite, so that the second positioning hole can be exposed on both sides of the third backing film.

[0075] By aligning the second positioning hole, the eighth composite on the ninth composite is die-cut so that the eighth composite has a finished product and a fourth frame waste.

[0076] After removing the waste from the fourth frame, the third support film and the finished product located on the third support film are obtained.

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

[0078] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application 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 this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
