Description

Technical Field

[0001] This invention relates to the field of foam material processing technology, and more specifically to a method for preparing concave grooves in foam materials. Background Technology

[0002] In a market environment where the demand for new energy batteries is constantly growing, melamine foam, as an important component of new energy batteries, plays a vital role due to its excellent heat insulation, sound insulation, and flame retardant properties. It not only improves battery efficiency and lifespan but also improves the battery's working environment, reduces its impact on the surrounding environment, and protects the safety of the battery and its surroundings. Therefore, the demand for melamine foam products is also increasing. Foam is a material made by foaming plastic particles.

[0003] Currently, battery pack manufacturing processes are constantly being upgraded. To ensure cushioning and insulation between internal components, the shape of the melamine foam must be designed to conform to the internal structure of the battery pack. The recessed grooves are designed to avoid the battery pack's wiring harnesses during actual assembly. The processing method for the melamine foam recessed groove structure is a stacking and assembly process, which involves cutting foam material sheets, applying adhesive, and then stacking and bonding them together. Figure 1 As shown, the first foam material board 11 is located at the bottom. The second foam material board 12 is attached to the left side of the surface of the first foam material board 11 using double-sided tape 14, and the third foam material board 13 is attached to the right side of the surface of the first foam material board 11 using double-sided tape 14. A concave groove 10 is formed between the first foam material board 11, the second foam material board 12, and the third foam material board 13. This production method involves many processes, uses a lot of materials, is inefficient, and has high costs, making it difficult to meet current production needs. The process of applying adhesive and then laminating the foam material boards may result in the foam material boards not sticking, increasing the cost of rework and causing production efficiency to fail to meet demand. It may also result in defective products flowing to downstream customers, causing abnormalities in customer use.

[0004] Other processing methods exist, such as wire cutting and milling on lathes. However, both wire cutting and milling processes generate material powder during the creation of concave grooves in foamed material boards. This powder adheres to the foamed material board, making cleaning difficult and affecting quality. Currently, CNC cutting machines lack cutting tools capable of creating concave grooves in a single operation. CNC cutting requires a combination of machining steps for longitudinal processing of foamed material boards, resulting in low production efficiency and increased raw material and labor costs, failing to meet customer needs. Therefore, it is necessary to optimize existing methods to improve production efficiency and reduce costs.

[0005] Therefore, how to quickly process concave grooves on foamed material boards, reduce the generation of material powder, and improve quality is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a method for preparing concave grooves in foamed materials, which can quickly process concave grooves in foamed material boards, reduce the generation of material powder, and improve quality.

[0007] This invention is achieved as follows: a method for preparing concave grooves in foamed materials, comprising the following steps: S1. Install the machining tool on the cutting drive device; The machining tool includes a base plate, a left side plate, a right side plate, and a top plate; The left and right sides of the base plate are fixedly connected to the left side plate and the right side plate, respectively. The front side of the base plate has a first blade and a second blade, the front side of the left side plate has a third blade, and the front side of the right side plate has a fourth blade. The first blade, the second blade, the third blade, and the fourth blade form an M-shaped cutting edge. The angle between the first blade and the second blade is an obtuse angle, and the angles between the third blade and the base plate and between the fourth blade and the base plate are both acute angles. The left and right sides of the top plate are fixedly connected to the left side plate and the right side plate respectively, and a discharge port is formed between the bottom plate, the left side plate, the right side plate and the top plate; Use a suction device to fix the foam material board; S2. Align the M-shaped cutting edge of the machining tool with the edge of the foam material board; S3. The cutting drive device moves the machining tool; S4. The cutting tool cuts out a concave groove on the surface of the foamed material board, and the waste generated during the cutting process passes through the discharge port of the cutting tool.

[0008] Furthermore, the cutting drive device is a CNC cutting machine tool, and the suction device is located on the base of the CNC cutting machine tool.

[0009] Furthermore, in S1, a cutting path is pre-set on the CNC cutting machine tool; Specifically, S3 refers to the CNC cutting machine tool moving the cutting tool along the cutting path.

[0010] Furthermore, the cutting path is a straight line.

[0011] Furthermore, the machining tool also includes a tool holder, which is fixedly connected to the upper surface of the top plate and is also fixedly connected to the cutting drive device.

[0012] Furthermore, the included angle between the first cutting edge and the second cutting edge is 120°±30°; The angle between the third blade and the base plate, and the angle between the fourth blade and the base plate are both 60°±15°.

[0013] Furthermore, the included angle between the first cutting edge and the second cutting edge is 300°±30°; The angle between the third blade and the base plate, and the angle between the fourth blade and the base plate are both 120°±15°.

[0014] Furthermore, the left and right side plates are both perpendicular to the bottom plate, and the top plate is parallel to the bottom plate.

[0015] Furthermore, the base plate, left side plate, and right side plate are integrally formed.

[0016] Compared with the prior art, the advantages of this invention are as follows: The M-shaped cutting tool, with its sharp point, carves concave grooves into the foamed material board in a single step. This invention reduces processing steps, improves production efficiency, and is suitable for mass production. During the processing of the concave grooves, the cutting tool smoothly cuts into the foamed material board, and the strip-shaped waste generated during the cutting process passes through the discharge port of the cutting tool, resulting in no material powder being generated. This avoids the abnormal phenomenon of powder adhering to the foamed material board product, which would affect product quality, and reduces the cost caused by rework. This invention quickly processes concave grooves into the foamed material board, reduces the generation of material powder, and improves quality. Attached Figure Description

[0030] This invention provides a method for preparing concave grooves in foamed materials, overcoming the shortcomings of previous techniques such as superimposed processing, wire cutting, and lathe milling in creating concave grooves in foamed material boards. It achieves the technical effect of creating concave grooves in foamed material boards in one step, reducing processing steps, improving production efficiency, being suitable for mass production, reducing material powder generation, and improving quality.

[0031] The overall concept of the technical solution of this invention is as follows: A new machining tool is manufactured for carving concave grooves into a foamed material board in a single process. The machining tool is equipped with an M-shaped cutting edge, which consists of a first cutting edge, a second cutting edge, a third cutting edge, and a fourth cutting edge. A sharp point is formed between the first and third cutting edges, and another sharp point is formed between the second and fourth cutting edges. The M-shaped cutting edge allows the machining tool to smoothly cut into the foamed material board. The strip-shaped waste generated during the cutting process passes through the discharge port of the machining tool, and no material powder is generated during the cutting process.

[0032] The cutting tool of the present invention is used in conjunction with a CNC cutting machine tool. The foam material board is fixedly mounted on the CNC cutting machine tool, and then the CNC cutting machine tool pushes the cutting tool of the present invention to carve out a concave groove on the foam material board along a preset cutting path.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] See Figures 1 to 11 The preferred embodiment of the present invention.

[0035] A method for preparing concave grooves in foamed materials includes the following steps: S1. Install the machining tool 2 onto the cutting drive device; The machining tool 2 includes a base plate 21, a left side plate 22, a right side plate 23, and a top plate 24; The left and right sides of the base plate 21 are fixedly connected to the left side plate 22 and the right side plate 23, respectively. The front side of the base plate 21 has a first blade 211 and a second blade 212. The front side of the left side plate 22 has a third blade 221. The front side of the right side plate 23 has a fourth blade 231. An M-shaped cutting edge is formed between the first blade 211, the second blade 212, the third blade 221, and the fourth blade 231. The included angle A between the first blade 211 and the second blade 212 is an obtuse angle. The included angle B between the third blade 221 and the base plate 21 and the included angle between the fourth blade 231 and the base plate 21 are both acute angles. The left and right sides of the top plate 24 are fixedly connected to the left side plate 22 and the right side plate 23 respectively, and a discharge port 25 is formed between the bottom plate 21, the left side plate 22, the right side plate 23 and the top plate 24; Use a suction device to fix the foam material board 1; Specifically, the cutting drive device is a CNC cutting machine tool; the suction device is located on the base of the CNC cutting machine tool. The suction device generates negative pressure to firmly hold the foam material board in place. A cutting path is pre-set on the CNC cutting machine tool; the cutting path is a straight line.

[0036] S2. Align the M-shaped cutting edge of the processing tool 2 with the edge of the foam material board 1; S3. The cutting drive device moves the machining tool 2; Specifically, the CNC cutting machine tool moves the machining tool along the cutting path.

[0037] S4. The processing tool 2 cuts out a concave groove 10 on the surface of the foamed material board 1, and the waste generated during the cutting process passes through the discharge port 25 of the processing tool 2.

[0038] The machining tool 2 with an M-shaped cutting edge and a sharp point 27 carves a concave groove 10 into the foamed material board 1 in one step. This invention reduces the number of processing steps, improves production efficiency, and is suitable for mass production. During the machining of the concave groove 10, the machining tool 2 smoothly cuts into the foamed material board 1. The strip-shaped waste generated during the cutting process passes through the discharge port 25 of the machining tool 2, without generating material powder. This prevents the abnormal phenomenon of powder adhering to the foamed material board 1 and affecting product quality, and reduces the cost caused by rework. This invention quickly processes the concave groove 10 into the foamed material board 1, reduces the generation of material powder, and improves quality.

[0039] The machining tool 2 also includes a tool holder 26, which is fixedly connected to the upper surface of the top plate 24 and is also fixedly connected to the cutting drive device.

[0040] Combined Figures 2 to 5 The included angle A between the first blade 211 and the second blade 212 is 120°±30°; The included angle B between the third cutting edge 221 and the base plate 21, and the included angle between the fourth cutting edge 231 and the base plate 21 are both 60°±15°. Here, a sharp point 27 is formed between the first cutting edge 211 and the third cutting edge 221, and another sharp point 27 is formed between the second cutting edge 212 and the fourth cutting edge 231.

[0041] Combined Figures 8 to 11 The included angle A between the first blade 211 and the second blade 212 is 300°±30°; The included angle B between the third cutting edge 221 and the base plate 21, and the included angle between the fourth cutting edge and the base plate are both 120°±15°. At this time, a sharp point is formed between the first cutting edge 211 and the second cutting edge 212.

[0042] The left side plate 22 and the right side plate 23 are both perpendicular to the bottom plate 21, and the top plate 24 is parallel to the bottom plate 21.

[0043] The base plate 21, left side plate 22, and right side plate 23 are integrally formed.

[0044] The processing tool 2 of the present invention is used to carve out a concave groove 10 in a foamed material board 1 in one step; the processing tool 2 is provided with an M-shaped cutting edge, which is composed of a first cutting edge 211, a second cutting edge 212, a third cutting edge 221 and a fourth cutting edge 231. The M-shaped cutting edge allows the processing tool 2 to smoothly cut into the foamed material board 1, and the strip-shaped waste generated during the cutting process passes through the discharge port 25 of the processing tool 2, and no material powder is generated during the cutting process.

[0045] The cutting tool of this invention is used in conjunction with a CNC cutting machine. By replacing the standard-sized cutting tool used in daily production on the CNC machine, adjusting the cutting path and height, and aligning the M-shaped cutting edge with the edge of the foamed material board, the cutting tool moves along the cutting path. The strip-shaped waste material generated during the cutting process passes through the discharge port, creating a concave groove in the foamed material board in one step. Subsequent production of similar concave grooves only requires changing the tool specifications, and this cutting process can be continued.

[0046] The beneficial effects achieved by the technical solution of this invention are as follows: 1. One-step cutting and forming, eliminating the need for stacking and combining processing steps, reducing processing operations, improving production efficiency, and suitable for mass production. During operation, melamine foam material is adsorbed and fixed onto a CNC cutting machine. The ordinary cutting tool is replaced with the processing tool of this invention, and the cutting path and height of the processing tool are adjusted to create a concave groove in the melamine foam material plate in one step. Compared to the previous method of using ordinary cutting tools with CNC cutting, the cutting process of the processing tool of this invention reduces the need for multiple cutting of different specifications of foam, foam coating and bonding, and suction processes for producing concave groove products, thus improving production efficiency and reducing labor and material costs.

[0047] 2. The M-shaped cutting edge allows the processing tool to smoothly cut into the foam material board without generating material powder. This prevents powder from adhering to the product and affecting product quality, thus reducing the cost increase caused by rework. Furthermore, compared to the processing methods of the prior art, the cutting process of this invention reduces the need for multiple manual waste removals after cutting and reduces abnormalities caused by adhesive bonding errors, thereby reducing additional material costs due to production errors.

[0048] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
