[0071] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0072] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present application. As used in the specification and the appended claims of the present application, the singular expressions "one", "a kind", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context. It should also be understood that in the embodiments of the present application, "one or more" refers to one, two or more; "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist; for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0073] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0074] The multiple involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first", "second", etc. are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0075] The product processing method provided by the embodiment of the present invention includes: compressing a to-be-formed part so that the surface of the compressed to-be-formed part has an imprint, wherein the imprint includes a concave portion, or the imprint includes concave portions and convex portions distributed alternately.

[0076] When the mark includes a concave portion, there may be one or more than two concave portions. The shape and size of the concave portion may be selected according to actual conditions, and this embodiment does not limit this.

[0077] In the case where the imprint includes alternately distributed concave and convex parts, there may be one or more concave parts, and there may be one or more convex parts. In the case where there are more than two concave parts and more than two convex parts, there is one convex part between two adjacent concave parts, and there is one concave part between two adjacent convex parts. The shape and size of the concave parts, as well as the shape and size of the convex parts, are selected according to actual conditions, and this embodiment does not limit this.

[0078] In the above-mentioned product processing method, since the imprint includes concave portions, or the imprint includes concave portions and convex portions distributed alternately, the imprint increases the surface area of ​​the part to be formed, so that the imprint can release the stress generated by stamping and other processing, thereby reducing the degree of distortion of the product, improving the flatness of the product, and improving the product qualification rate.

[0079] The welding yield of the product obtained by the above product processing method can be improved by welding the product with other components.

[0080] In the above production method, the surface of the compressed part to be formed has a mark, and the specific position of the mark is selected according to actual conditions.

[0081] In order to increase the range of the mark, in the above-mentioned product processing method, the part to be formed is compressed so that the surface of the compressed part to be formed has a mark, specifically including: compressing the upper surface of the part to be formed so that the upper surface of the compressed part to be formed has a mark; or, compressing the lower surface of the part to be formed so that the lower surface of the compressed part to be formed has a mark.

[0082] It should be noted that the upper surface and the lower surface of the product are relatively distributed, and the upper surface and the lower surface of the product can be two surfaces in the height direction of the product, two surfaces in the length direction of the product, or two surfaces in other directions of the product.

[0083] In order to increase the distribution range of the mark, the upper surface and / or the lower surface is the surface with the largest area among the product surfaces.

[0084] In order to maximize the range of the mark, in the above product processing method, compressing the part to be formed so that the surface of the compressed part to be formed has a mark, specifically includes: compressing the upper surface of the part to be formed so that the upper surface of the compressed part to be formed has a mark; compressing the lower surface of the part to be formed so that the lower surface of the compressed part to be formed has a mark. The shape of the mark on the upper surface and the shape of the mark on the lower surface can be the same or different, and the number of marks on the upper surface and the number of marks on the lower surface can be the same or different.

[0085] In the above-mentioned product processing method, you can choose to compress the upper surface and the lower surface of the part to be formed at the same time, or you can choose to compress the upper surface of the part to be formed first and then the lower surface of the part to be formed, or you can choose to compress the lower surface of the part to be formed first and then the upper surface of the part to be formed, according to the actual situation, and this embodiment does not limit this.

[0086] In the above-mentioned product processing method, on the one hand, the part to be formed can be selected to be compressed so that the surface of the compressed part to be formed has an imprint, which specifically includes: compressing the part to be formed so that the upper surface and the lower surface of the compressed part to be formed both have concave parts, and the concave parts on the upper surface of the part to be formed and the concave parts on the lower surface of the part to be formed are opposite to each other. In this case, the upper surface of the compressed part to be formed may also have a convex part, and / or the lower surface of the compressed part to be formed may also have a convex part. In the case where the upper surface and the lower surface of the compressed part to be formed also have convex parts, compressing the part to be formed so that the surface of the compressed part to be formed has an imprint, which specifically includes: compressing the part to be formed so that the upper surface and the lower surface of the compressed part to be formed both have concave parts and convex parts, and the concave parts on the upper surface of the part to be formed and the concave parts on the lower surface of the part to be formed are opposite to each other, and the convex parts on the upper surface of the part to be formed and the convex parts on the lower surface of the part to be formed are opposite to each other.

[0087] It should be noted that the concave portion on the upper surface of the part to be molded and the concave portion on the lower surface of the part to be molded are relative, which means that the projection of the concave portion on the upper surface of the part to be molded along the depth direction and the projection of the concave portion on the lower surface of the part to be molded along the depth direction completely overlap, or the projection of the concave portion on the upper surface of the part to be molded along the depth direction and the projection of the concave portion on the lower surface of the part to be molded along the depth direction partially overlap.

[0088] The convex portion of the upper surface of the part to be molded and the convex portion of the lower surface of the part to be molded are relative, which means that the projection of the convex portion of the upper surface of the part to be molded along the height direction and the projection of the convex portion of the lower surface of the part to be molded along the height direction completely overlap, or the projection of the convex portion of the upper surface of the part to be molded along the height direction and the projection of the convex portion of the lower surface of the part to be molded along the height direction partially overlap.

[0089] The depth direction of the concave portion is perpendicular to the upper and lower surfaces of the part to be formed, the height direction of the convex portion is perpendicular to the upper and lower surfaces of the part to be formed, and the depth direction of the concave portion is consistent with the height direction of the convex portion.

[0090] On the other hand, the part to be formed can be compressed so that the surface of the compressed part to be formed has an imprint, which specifically includes: compressing the part to be formed so that the upper surface and the lower surface of the compressed part to be formed have concave parts, and the concave parts on the upper surface of the part to be formed and the concave parts on the lower surface of the part to be formed are misaligned. In this case, the upper surface of the compressed part to be formed may also have a convex part, and / or the lower surface of the compressed part to be formed may also have a convex part. In the case where the upper surface and the lower surface of the compressed part to be formed also have convex parts, compressing the part to be formed so that the surface of the compressed part to be formed has an imprint, which specifically includes: compressing the part to be formed so that the upper surface and the lower surface of the compressed part to be formed have concave parts and convex parts, and the concave parts on the upper surface of the part to be formed and the concave parts on the lower surface of the part to be formed are misaligned, and the convex parts on the upper surface of the part to be formed and the convex parts on the lower surface of the part to be formed are misaligned. It can be understood that the concave portion on the upper surface of the to-be-formed piece and the convex portion on the lower surface of the to-be-formed piece are opposite to each other, and the convex portion on the upper surface of the to-be-formed piece and the concave portion on the lower surface of the to-be-formed piece are opposite to each other.

[0091] It should be noted that the misalignment of the concave portion on the upper surface of the part to be formed and the concave portion on the lower surface of the part to be formed means that the projection of the concave portion on the upper surface of the part to be formed along the depth direction and the projection of the concave portion on the lower surface of the part to be formed along the depth direction have no overlapping portion.

[0092] The misalignment of the convex portion on the upper surface of the part to be formed and the convex portion on the lower surface of the part to be formed means that the projection of the convex portion on the upper surface of the part to be formed along the height direction and the projection of the convex portion on the lower surface of the part to be formed along the height direction have no overlapping portion.

[0093] Of the above two aspects, the former can release more stress than the latter, and thus the former can more effectively release the stress generated by stamping and other processing than the latter, further reducing the degree of distortion of the product, further improving the flatness of the product, and thus further improving the product qualification rate.

[0094] On the other hand, the part to be formed can be compressed so that the surface of the compressed part to be formed has an imprint, specifically including: compressing the part to be formed so that the upper surface and the lower surface of the compressed part to be formed have concave parts, and a part of the concave parts on the upper surface of the part to be formed and a part of the concave parts on the lower surface of the part to be formed are opposite, and another part of the concave parts on the upper surface of the part to be formed and another part of the concave parts on the lower surface of the part to be formed are offset. In this case, the upper surface of the compressed part to be formed may also have a convex part, and / or the lower surface of the compressed part to be formed may also have a convex part. In the case that the upper surface and the lower surface of the part to be formed after compression still have convex portions, compressing the part to be formed so that the surface of the compressed part to be formed has an imprint, specifically includes: compressing the part to be formed so that the upper surface and the lower surface of the part to be formed after compression have concave portions and convex portions, and a part of the concave portions on the upper surface of the part to be formed and a part of the concave portions on the lower surface of the part to be formed are opposite to each other, another part of the concave portions on the upper surface of the part to be formed and another part of the concave portions on the lower surface of the part to be formed are offset, a part of the convex portions on the upper surface of the part to be formed and a part of the convex portions on the lower surface of the part to be formed are opposite to each other, and another part of the convex portions on the upper surface of the part to be formed and another part of the convex portions on the lower surface of the part to be formed are offset.

[0095] In the above product processing method, the molded part can be compressed only once or at least twice. The specific number of compressions is selected according to actual conditions as long as the flatness of the product is ensured, and this embodiment does not limit this.

[0096] In order to better release stress and reduce the degree of distortion of the product, the molded part can be compressed at least twice.

[0097] In the above product processing method, compressing the molded part at least twice specifically includes: first compressing the molded part last time, and then compressing the molded part next time. The specific steps of the last compression and the next compression are selected according to actual conditions.

[0098] It should be noted that, when the molded part is compressed at least twice, the last compression and the next compression may be two adjacent compressions or two non-adjacent compressions. For example, the last compression and the next compression may be the last two compressions, the first two compressions, or the middle two compressions. This embodiment does not limit this.

[0099] On the one hand, the last compression of the part to be formed can be selected, specifically: the last compression of the part to be formed is such that both the upper surface and the lower surface of the part to be formed after compression have concave parts, and the concave parts on the upper surface of the part to be formed are opposite to the concave parts on the lower surface of the part to be formed; the next compression of the part to be formed is specifically: the next compression of the part to be formed is such that both the upper surface and the lower surface of the part to be formed after compression have concave parts, and the concave parts on the upper surface of the part to be formed are misaligned with the concave parts on the lower surface of the part to be formed. In this way, a part of the concave parts on the upper surface of the part to be formed is opposite to a part of the concave parts on the lower surface of the part to be formed, and another part of the concave parts on the upper surface of the part to be formed is misaligned with another part of the concave parts on the lower surface of the part to be formed. Moreover, compared with the imprint obtained by the last compression and the imprint obtained by the next compression, the imprint obtained by the last compression can release more stress, so that the imprint obtained by the last compression can more effectively release the stress generated by processing such as stamping.

[0100] In actual situations, it is also possible to choose to compare the mark obtained by the last compression with the mark obtained by the next compression, so that the mark obtained by the next compression can release more stress, which is not limited to the above situation.

[0101] Of course, the realization that a portion of the recessed portion on the upper surface of the part to be formed is opposite to a portion of the recessed portion on the lower surface of the part to be formed, and another portion of the recessed portion on the upper surface of the part to be formed is offset from another portion of the recessed portion on the lower surface of the part to be formed, can also be achieved by compressing the part to be formed only once, and this is not limited to the present embodiment.

[0102] On the other hand, the last compression of the to-be-formed part is specifically: the last compression of the to-be-formed part is such that the upper and lower surfaces of the compressed to-be-formed part both have concave parts, and the concave parts on the upper surface of the to-be-formed part and the concave parts on the lower surface of the to-be-formed part are opposite to each other; the next compression of the to-be-formed part is specifically: the next compression of the to-be-formed part is such that the upper and lower surfaces of the compressed to-be-formed part both have concave parts, and the concave parts on the upper surface of the to-be-formed part and the concave parts on the lower surface of the to-be-formed part are opposite to each other. In this way, it can be achieved that the upper and lower surfaces of the compressed to-be-formed part both have concave parts, and the concave parts on the upper surface of the to-be-formed part and the concave parts on the lower surface of the to-be-formed part are opposite to each other.

[0103] Of course, the realization that both the upper and lower surfaces of the compressed part have recesses, and the recesses on the upper surface of the part to be formed are opposite to the recesses on the lower surface of the part to be formed, can be achieved by compressing the part to be formed only once.

[0104] On the other hand, the last compression of the to-be-formed part is specifically: the last compression of the to-be-formed part is such that the upper and lower surfaces of the compressed to-be-formed part both have concave parts, and the concave parts on the upper surface of the to-be-formed part and the concave parts on the lower surface of the to-be-formed part are misaligned; the next compression of the to-be-formed part is specifically: the next compression of the to-be-formed part is such that the upper and lower surfaces of the compressed to-be-formed part both have concave parts, and the concave parts on the upper surface of the to-be-formed part and the concave parts on the lower surface of the to-be-formed part are misaligned. In this way, it can be achieved that the upper and lower surfaces of the compressed to-be-formed part both have concave parts, and the concave parts on the upper surface of the to-be-formed part and the concave parts on the lower surface of the to-be-formed part are misaligned.

[0105] Of course, the realization that both the upper and lower surfaces of the compressed part to be formed have recesses and the recesses on the upper surface of the part to be formed and the recesses on the lower surface of the part to be formed are offset can be achieved by compressing the part to be formed only once.

[0106] In the above product processing method, the specific compression conditions of the last compression and the next compression are selected according to the actual situation.

[0107] In one aspect, the molded article may be compressed at least twice, including:

[0108] The part to be formed is compressed last time and then compressed next time, so that the number of marks obtained by the last compression is equal to the number of marks obtained by the next compression, or the number of marks obtained by the last compression is greater than the number of marks obtained by the next compression, or the number of marks obtained by the last compression is less than the number of marks obtained by the next compression.

[0109] In order to reduce the degree of distortion of the product, the part to be formed may be compressed last time before being compressed next time, so that the number of marks obtained by the last compression is greater than the number of marks obtained by the next compression.

[0110] It should be noted that, when the imprint includes concave portions, the number of the imprint is the number of the concave portions; when the imprint includes concave portions and convex portions, the number of the imprint includes the number of the concave portions and the number of the convex portions.

[0111] When the mark includes concave and convex parts, the number of marks obtained by the last compression is equal to that obtained by the next compression, that is, the number of concave parts obtained by the last compression is equal to that obtained by the next compression, and the number of convex parts obtained by the last compression is equal to that obtained by the next compression.

[0112] When the mark includes concave parts and convex parts, the number of marks obtained by the last compression is greater than the number of marks obtained by the next compression, that is, the number of concave parts obtained by the last compression is greater than the number of concave parts obtained by the next compression, and the number of convex parts obtained by the last compression is greater than the number of convex parts obtained by the next compression.

[0113] When the mark includes concave parts and convex parts, the number of marks obtained by the last compression is smaller than the number of marks obtained by the next compression, that is, the number of concave parts obtained by the last compression is smaller than the number of concave parts obtained by the next compression, and the number of convex parts obtained by the last compression is smaller than the number of convex parts obtained by the next compression.

[0114] In another aspect, the molded article is compressed at least twice, including:

[0115] The molded part is compressed last time and then compressed next time, so that the shape of the mark obtained by the last compression is the same as that of the mark obtained by the next compression, or the shape of the mark obtained by the last compression is different from that of the mark obtained by the next compression.

[0116] Of course, you can also choose to compress the part to be formed last time and then compress it next time, so that part of the mark obtained by the last compression has the same shape as part of the mark obtained by the next compression, and another part of the mark obtained by the last compression has different shapes from another part of the mark obtained by the next compression.

[0117] It should be noted that, when the imprint includes a concave portion, the shape of the imprint is the shape of the concave portion; when the imprint includes a concave portion and a convex portion, the shape of the imprint includes the shape of the concave portion and the shape of the convex portion.

[0118] When the mark includes concave and convex parts, the shape of the mark obtained by the last compression is the same as that obtained by the next compression, that is, the shape of the concave parts obtained by the last compression is the same as that obtained by the next compression, and the shape of the convex parts obtained by the last compression is the same as that obtained by the next compression.

[0119] When the mark includes concave and convex parts, the shapes of the mark obtained by the last compression are different from those of the mark obtained by the next compression, that is, the shape of the concave parts obtained by the last compression is different from the shape of the concave parts obtained by the next compression, and the shape of the convex parts obtained by the last compression is different from the shape of the convex parts obtained by the next compression.

[0120] In some embodiments, in order to effectively release the stress generated by stamping, the product processing method may further include: processing the part to be formed between two compressions of the part to be formed. The processing of the part to be formed includes processing the part to be formed by stamping.

[0121] In the above method, the part to be formed is first compressed, then processed by stamping, and then compressed again, which can better release the stress generated by stamping.

[0122] The part to be formed is processed by punching, specifically, the shape of the part to be formed is precisely cut by punching. Of course, other processing methods can also be selected to process the part to be formed by punching, and are not limited to the above-mentioned precisely cutting the shape of the part to be formed.

[0123] In actual situations, a mold may be selected to process the molded part by stamping. In order to facilitate the setting of the mold for processing the molded part by stamping, it may be selected to further include: making the molded part idle between compressing the molded part and processing the molded part by stamping. In this way, by setting the idle step, the distance between the two stations of compressing the molded part and processing the molded part by stamping is increased, thereby facilitating the setting of the mold.

[0124] In order to better illustrate the product processing method provided by this embodiment, five embodiments are described below.

[0125] Embodiment 1

[0126] like Figure 1 As shown, the product processing method provided in the first embodiment of the present invention includes:

[0127] S11: compressing the part to be formed so that both the upper surface and the lower surface of the compressed part to be formed have marks;

[0128] S12: Processing the compressed molded parts.

[0129] In the above S11, the imprint may include a concave portion, or the imprint may include concave portions and convex portions distributed alternately.

[0130] In the above S11, the molded part can be compressed by a product processing mold. Fig.13 and Fig.14 As shown, the product processing mold includes an upper mold assembly 310 and a lower mold assembly 320, the upper mold assembly 310 is provided with a first protrusion 330, and the lower mold assembly 320 is provided with a second protrusion 340. The part to be formed (the part to be formed may be a stamping strip 1) is placed on the lower mold assembly 320, and the upper mold assembly 310 moves toward the lower mold assembly 320 to compress the part to be formed. The first protrusion 330 compresses the part to be formed so that the upper surface of the part to be formed has concave parts and protrusions distributed alternately, or the upper surface of the part to be formed has a concave part. It can be understood that a concave part appears at a position opposite to the first protrusion 330 in the upper surface of the part to be formed, and a protrusion may be formed at other positions of the upper surface of the part to be formed except the position opposite to the first protrusion 330, or no protrusion may be formed. The second protrusion 340 compresses the part to be formed so that the lower surface of the part to be formed has concave parts and protrusions distributed alternately, or the lower surface of the part to be formed has a concave part. It is understandable that a concave portion appears at a position of the lower surface of the molded part opposite to the second protrusion 340 , and a convex portion may or may not be formed at other positions of the lower surface of the molded part except the position opposite to the second protrusion 340 .

[0131] The size, shape, number and distribution of the above-mentioned concave and convex parts are selected according to actual conditions, and this embodiment does not limit this.

[0134] Of course, the part to be formed may also be processed by stamping before S11, between S11 and S12, or after S12, depending on the actual situation, and this embodiment does not limit this.

[0135] In the product processing method provided in the above-mentioned embodiment 1, the workpiece to be formed is compressed so that the surface of the compressed workpiece to be formed has an imprint. Since the imprint includes a concave portion, or the imprint includes concave portions and convex portions distributed alternately, the imprint increases the surface area of ​​the workpiece to be formed, so that the imprint can release the stress generated by processing such as stamping, thereby reducing the degree of distortion of the product, improving the flatness of the product, and improving the qualified rate of the product; moreover, the workpiece to be formed is first compressed, and then the compressed workpiece to be formed is processed by stamping, so that the stress generated by stamping can be better released, further improving the qualified rate of the product.

[0136] The product processing method provided in the first embodiment can be realized by a progressive die, thereby improving the production efficiency of the product.

[0137] In the product processing method provided in the above embodiment 1, for the convenience of processing, the thickness of the molded part can be 0.1 mm to 1.0 mm. Of course, the thickness of the molded part can also be selected to be other thicknesses, which is not limited in this embodiment.

[0138] In the product processing method provided in the first embodiment, the number of times the molded part is compressed may be one or more than two times. The specific number of times the molded part is compressed is selected according to the actual situation, as long as the flatness of the molded part meets the requirements.

[0139] Embodiment 2

[0144] At least one of the above S21 and S24 includes: processing the molded part by stamping. The specific processing method of processing the molded part before compression by stamping is selected according to actual conditions, and this embodiment does not limit this.

[0145] In the above-mentioned second embodiment, stamping is performed first and then compression, so that the mark obtained by compression can also release the stress generated by stamping and other processing.

[0146] The above-mentioned S23, in which an empty step is set, is to increase the distance between the station executing S22 and the station executing S24, so as to facilitate the installation of product processing molds or other equipment.

[0147] In other embodiments, the above S23 may be removed, that is, directly go from S22 to S24.

The bottom surface of the upper mold assembly 310 has a first protrusion 330, and the top surface of the lower mold assembly 320 has a second protrusion 340. The first protrusion 330 of the upper mold assembly 310 acts on the upper surface of the stamping strip 1, and the second protrusion 340 of the lower mold assembly 320 acts on the lower surface of the stamping strip 1. During use, the upper mold assembly 310 and the lower mold assembly 320 are first separated, and the stamping strip 1 is placed on the top surface of the lower mold assembly 320, as shown in FIG. Fig.13 Then the upper mold assembly 310 is pressed against the lower mold assembly 320, so that the first protrusion 330 of the upper mold assembly 310 and the second protrusion 340 of the lower mold assembly 320 compress the stamping strip 1, as Fig.14 As shown, the upper and lower surfaces of the stamping strip 1 have concave and convex portions distributed alternately. It can be understood that the position on the stamping strip 1 opposite to the first protrusion 330 and the position opposite to the second protrusion 340 form a concave portion, and a convex portion may or may not be formed between two adjacent concave portions.

[0269] In order to facilitate the setting of the first protrusion 330 and the second protrusion 340, the upper mold assembly 310 can be optionally provided with an upper punching plate, the first protrusion 330 is provided on the upper punching plate, and the lower mold assembly 320 is provided with a lower punching plate, the second protrusion 340 is provided on the lower punching plate.

[0270] The number and distribution of the first protrusions 330 and the second protrusions 340 are selected according to actual conditions, and are not limited in this embodiment.

[0271] The first protrusion 330 and the second protrusion 340 may both be referred to as protrusions. In order to release the stress generated by stamping, the protrusion may be selected to be a tapered structure, and the protrusion tapers from the connection end to the free end. The connection end of the first protrusion 330 is the end where the first protrusion 330 is connected to the upper mold assembly 310, and the free end of the first protrusion 330 is the end of the first protrusion 330 away from the upper mold assembly 310. The connection end of the second protrusion 340 is the end where the second protrusion 340 is connected to the lower mold assembly 320, and the free end of the second protrusion 340 is the end where the second protrusion 340 is away from the lower mold assembly 320.

[0272] The protrusion may be in the shape of a truncated cone or a prism, which is not limited in this embodiment.

[0273] In actual situations, the protrusions may also be selected to have other structures, such as a cube or a rectangular parallelepiped, etc., which is not limited in this embodiment.

[0274] Fig.13 and Fig.14The product processing mold shown is suitable for the following product processing methods:

[0275] The part to be formed is compressed so that both the upper surface and the lower surface of the compressed part to be formed have marks.

[0276] In some embodiments, the upper mold assembly 310 is not provided with the first protrusion 330, and the top surface of the lower mold assembly 320 has the second protrusion 340. In this case, the product processing method applicable to the product processing mold is:

[0277] The parts to be formed are compressed so that the lower surfaces of the compressed parts to be formed have marks.

[0278] In some embodiments, the bottom surface of the upper mold assembly 310 is also selected to have the first protrusion 330, and the lower mold assembly 320 is not provided with the second protrusion 340. In this case, the product processing method applicable to the product processing mold is:

[0279] The parts to be formed are compressed so that the upper surfaces of the compressed parts to be formed have marks.

[0280] In order to improve production efficiency, the product processing mold can be selected as a progressive die. In this case, the product processing methods provided in the above embodiments 1, 2, 3, 4 and 5 can all be completed by a progressive die.

[0281] like Figure 15-17 As shown, the product processing die is a progressive die, which mainly includes: an upper die assembly 310 and a lower die assembly 320 , and the stamping strip 1 is located between the upper die assembly 310 and the lower die assembly 320 . Fig.15 The status shown is the working status of the product processing mold.

[0282] In the case of two compressions, the first compression is performed at the first compression position 350 of the progressive die, and the second compression is performed at the second compression position 360 of the progressive die. In the case of one compression, compression may be performed only at the first compression position 350 of the progressive die.

[0283] like Fig.15 and Fig.16 As shown, in the first compression position 350 of the progressive die, the first protrusion 330 of the upper die assembly 310 and the second protrusion 340 of the lower die assembly 320 are arranged opposite to each other, so that after the first compression, the concave portion of the upper surface of the stamped strip 1 and the concave portion of the lower surface of the stamped strip 1 are opposite to each other, and the convex portion of the upper surface of the stamped strip 1 and the convex portion of the lower surface of the stamped strip 1 are opposite to each other; as shown in FIG. Fig.15 and Fig.17As shown, in the second compression position 360 of the progressive die, the first protrusion 330 of the upper mold assembly 310 and the second protrusion 340 of the lower mold assembly 320 are staggered, that is, the positions of the first protrusion 330 and the two adjacent second protrusions 340 in the lower mold assembly 320 are relative, so that the concave portion of the upper surface obtained after the second compression is opposite to the convex portion of the lower surface obtained after the second compression, and the convex portion of the upper surface obtained after the second compression is opposite to the concave portion of the lower surface obtained after the second compression.

[0284] In actual situations, the relative positions of the first protrusion 330 and the second protrusion 340 in the compression position (the first compression position 350 and / or the second compression position 360) of the progressive film can be adjusted, and are not limited to Fig.16 and Fig.17 The relative positions shown.

[0285] Based on the product processing method provided in the above embodiment, an embodiment of the present invention further provides a product, which is a stamping part, and a mark is provided on the surface of the product, and the mark includes a concave portion, or the mark includes concave portions and convex portions distributed alternately.

[0286] When the mark includes a concave portion, there may be one or more than two concave portions. The shape and size of the concave portion may be selected according to actual conditions, and this embodiment does not limit this.

[0287] In the case where the imprint includes alternately distributed concave and convex parts, there may be one or more concave parts, and there may be one or more convex parts. In the case where there are more than two concave parts and more than two convex parts, there is one convex part between two adjacent concave parts, and there is one concave part between two adjacent convex parts. The shape and size of the concave parts, as well as the shape and size of the convex parts, are selected according to actual conditions, and this embodiment does not limit this.

[0288] In the above-mentioned product, since the mark includes a concave portion, or the mark includes alternately distributed concave portions and convex portions, the mark increases the surface area of ​​the part to be formed, so that the mark can release the stress generated by stamping and other processing, thereby reducing the degree of distortion of the product, improving the flatness of the product, and improving the qualified rate of the product. The above-mentioned product can be welded with other parts to improve the welding yield of the product.

[0289] In the above product, the imprint is at least located on at least one surface of the product surface. The specific location of the imprint is selected according to actual conditions.

[0290] To facilitate the placement of the imprint, the imprint may be located on the upper and / or lower surface of the product.

[0291] It should be noted that the upper surface and the lower surface of the product are relatively distributed, and the upper surface and the lower surface of the product can be two surfaces in the height direction of the product, two surfaces in the length direction of the product, or two surfaces in other directions of the product.

[0292] In order to increase the distribution range of the mark, the upper surface and / or the lower surface is the surface with the largest area among the product surfaces.

[0293] In some embodiments, in order to maximize the range of the imprint, the imprint is located on the upper surface and the lower surface of the product. The shape of the imprint on the upper surface and the shape of the imprint on the lower surface may be the same or different, and the number of imprints on the upper surface and the number of imprints on the lower surface may be the same or different.

[0294] In the above embodiment, on one hand, the concave portion on the upper surface of the product and the concave portion on the lower surface of the product can be selected to be opposite. In this case, the upper surface of the product can also have a convex portion, and / or the lower surface of the product can also have a convex portion.

[0295] When both the upper and lower surfaces of the product have convex portions, or both the upper and lower surfaces of the product have concave portions, the concave portions on the upper surface of the product and the concave portions on the lower surface of the product are opposite to each other, and the convex portions on the upper surface of the product and the convex portions on the lower surface of the product are opposite to each other.

[0296] It should be noted that the concave portion on the upper surface of the product and the concave portion on the lower surface of the product are relative, which means that the projection of the concave portion on the upper surface of the product along the depth direction and the projection of the concave portion on the lower surface of the product along the depth direction completely overlap with each other, or the projection of the concave portion on the upper surface of the product along the depth direction and the projection of the concave portion on the lower surface of the product along the depth direction partially overlap with each other.

[0297] The convex portion of the upper surface of the product and the convex portion of the lower surface of the product are relative to each other, which means that the projection of the convex portion of the upper surface of the product along the height direction and the projection of the convex portion of the lower surface of the product along the height direction completely overlap with each other, or the projection of the convex portion of the upper surface of the product along the height direction and the projection of the convex portion of the lower surface of the product along the height direction partially overlap with each other.

[0298] The depth direction of the concave portion is perpendicular to the upper surface and the lower surface of the product, the height direction of the convex portion is perpendicular to the upper surface and the lower surface of the product, and the depth direction of the concave portion and the height direction of the convex portion are consistent.

[0299] On the other hand, the recessed portion on the upper surface of the product and the recessed portion on the lower surface of the product may be staggered. In this case, the upper surface of the product may also have a convex portion, and / or the lower surface of the product may also have a convex portion.

[0300] In the case where both the upper and lower surfaces of the product have convex portions, or both the upper and lower surfaces of the product have concave portions, the concave portions on the upper surface of the product and the concave portions on the lower surface of the product are misaligned, and the convex portions on the upper surface of the product and the convex portions on the lower surface of the product are misaligned, that is, the concave portions on the upper surface of the product and the convex portions on the lower surface of the product are opposite to each other, and the convex portions on the upper surface of the product and the concave portions on the lower surface of the product are opposite to each other.

[0301] It should be noted that the misalignment of the concave portion on the upper surface of the product and the concave portion on the lower surface of the product means that there is no overlapping portion between the projection of the concave portion on the upper surface of the product and the projection of the concave portion on the lower surface of the product along the depth direction.

[0302] The misalignment of the convex portion on the upper surface of the product and the convex portion on the lower surface of the product means that there is no overlapping portion between the projection of the convex portion on the upper surface of the product along its height direction and the projection of the convex portion on the lower surface of the product along its height direction.

[0303] On the other hand, a part of the concave portion on the upper surface of the product and a part of the concave portion on the lower surface of the product may be opposite, and another part of the concave portion on the upper surface of the product and another part of the concave portion on the lower surface of the product may be offset. In this case, the upper surface of the product may also have a convex portion, and / or the lower surface of the product may also have a convex portion.

[0304] In the case where both the upper and lower surfaces of the product have convexities, or both the upper and lower surfaces of the product have concaveities, it can be selected that a portion of the concave portions on the upper surface of the product is opposite to a portion of the concave portions on the lower surface of the product, another portion of the concave portions on the upper surface of the product is staggered with another portion of the concave portions on the lower surface of the product, a portion of the convex portions on the upper surface of the product is opposite to a portion of the convex portions on the lower surface of the product, and another portion of the convex portions on the upper surface of the product is staggered with another portion of the convex portions on the lower surface of the product.

[0305] In the above products, the imprint can be one or more than two, which can be selected according to actual conditions. In some embodiments, the imprint is at least two, and the shapes of at least two imprints are different.

[0306] Of course, when any two marks have the same shape, at least two marks may be selected to have different sizes. In this case, there are also at least two marks.

[0307] The types of the above products are selected according to actual conditions. In some embodiments, the product is a plate of a plate heat exchanger.

[0308] The plates of the plate heat exchanger can be horizontal flow plates. Figure 18-Figure 20 As shown, the plate surface of the flat flow plate 100 has concave and convex parts 103, and the concave and convex parts 103 extend along the length direction of the flat flow plate 100. The upper surface of the flat flow plate 100 has concave parts 101 and convex parts 102 distributed alternately, and the lower surface of the flat flow plate 100 has concave parts and convex parts distributed alternately.

[0309] The plates of the plate heat exchanger can be point wave plates. Figure 21-23 As shown, the surface of the dot wave plate 200 has a concave-convex portion 203, and the concave-convex portion 203 extends along the length direction of the dot wave plate 200. The upper surface of the dot wave plate 200 has concave portions 201 and convex portions 202 that are distributed alternately. The upper surface of the dot wave plate 200 also has a convex portion 204. The lower surface of the dot wave plate 200 has concave portions and convex portions that are distributed alternately. The convex portions 204 are distributed in a set manner. It should be noted that the distribution of the convex portions 204 is not limited to Fig.21 The distribution shown.

[0310] In actual situations, the plates of the plate heat exchanger may also be selected to have other structures, and this embodiment does not limit the specific structure of the plates of the plate heat exchanger.

[0311] The product provided in the above embodiment may also be other components, such as a cover plate, etc. This embodiment does not limit the specific type of the product.
