Description

Technical Field

[0001] This application relates to the field of stamping technology, and in particular to blanking devices and blanking methods. Background Technology

[0002] Uncoiling and blanking is a common processing method in the production of stamped parts. Its work involves uncoiling and leveling metal coils on the uncoiling and blanking production line, and then passing them through blanking dies to cut the long strip of material according to a certain step distance and rhythm, thereby achieving the purpose of producing sheet metal of a specific size or shape.

[0003] The blanking die consists of an upper die body, a lower die body, and a cutting tool that are positioned opposite each other. Material is conveyed between the upper and lower die bodies. The upper and lower die bodies move up and down to engage, causing the cutting tool to move and cut the material. During the conveying process, the material slides on the upper part of the lower die body for a long time. During cutting, the material makes rigid contact with the corresponding die body, or debris adheres to the surface of the material or the upper and lower die bodies, making the material prone to scratches or abrasions. Furthermore, sometimes the material size is too small, or the material movement speed is too fast, resulting in low blanking accuracy when the material is only pressed at the cutting tool position.

[0063] See Figure 1-2 An embodiment of this application provides a material feeding device, including a first mold 1, a second mold 2, a conveying assembly 3, a pressing assembly 4, and a cutting assembly 5. The first mold 1 and the second mold 2 are stacked together along a first direction and can move closer or further apart along the first direction to perform material feeding and pressing operations. Material 7 is conveyed between the first mold 1 and the second mold 2 along a second direction. The second direction intersects the first direction, i.e., the first direction and the second direction are different directions and have an included angle, which can be, but is not limited to, a right angle or an acute angle. The conveying assembly 3 is installed on the second mold 2 to elastically support the material 7, reducing scratches or abrasions caused by rigid contact between the material 7 and the second mold 2. The pressing assembly 4 is installed on the first mold 1 and is used to elastically abut against the material 7, driving the material 7 to abut against the conveying assembly 3, so as to reduce scratches or abrasions caused by rigid contact between the material 7 and the first mold 1. The cutting component 5 is installed between the first mold body 1 and the second mold body 2 for cutting the material 7. The cutting component 5 may be, but is not limited to, a cutting tool.

[0064] With this configuration, during blanking, the first mold body 1 and the second mold body 2 move closer to each other, causing the conveying component 3 and the pressing component 4 to elastically abut against the opposite surfaces of the material 7. This allows the conveying component 3 and the pressing component 4 to elastically clamp the material 7 on both sides during the cutting process of the cutting component 5, ensuring accurate and stable pressing action. At the same time, it reduces rigid contact between the material 7 and the first mold body 1, and between the material 7 and the second mold body 2 during the conveying and cutting process, reducing scratches or abrasions on the material 7, improving the quality of the finished product after blanking, and solving the problems of easy scratching of the material 7 and low pressing accuracy during blanking.

[0065] In this embodiment, the conveying component 3 and the pressing component 4 may be, but are not limited to, made of elastic materials. Alternatively, the conveying component 3 and the pressing component 4 may also employ mechanical structures capable of elastic deformation, such as springs, both of which can elastically abut against the material 7. Optionally, the first direction and the second direction may be perpendicular to each other, see reference. Figure 1 As shown, the first direction can be along the Z-axis, referring to the vertical direction between the first mold body 1 and the second mold body 2. The second direction can be along the X-axis, referring to the front-back direction between the first mold body 1 and the second mold body 2. The material 7 can be, but is not limited to, sheet metal or block material. The blanking device can unwind and blank the material 7. The width of the material 7 can be 0.8 meters to 2.1 meters. The blanking device can be installed on a blanking production line. The second mold body 2 can be fixed in position, and the first mold body 1 can be driven by a drive device to reciprocate in the first direction. Mounting slots can be provided on both sides of the first mold body 1 and the second mold body 2 for quick-clamp installation.

[0066] See Figure 3-5 In some embodiments, when producing square or trapezoidal sheet metal, only a universal blanking die or shearing blade is needed. However, when producing sheet metal of other shapes such as wavy shapes, a dedicated uncoiling and blanking die is often required, resulting in poor versatility between blanking dies. Therefore, the connection between the cutting assembly 5 and the first mold body 1 and the second mold body 2 is a detachable connection. This connection can be, but is not limited to, snap-fit, bolt connection, or magnetic connection, making disassembly and connection convenient. Multiple cutting assemblies 5 are provided, each corresponding to a different cutting edge. Different cutting edges can cut the material 7 into different shapes. The cutting edges can be designed into different shapes according to the blanking requirements; for example, the cutting edges can be wavy or curved.

[0067] Multiple cutting mounting positions 11 and multiple pressing mounting positions 12 are provided along the second direction on the first mold body 1 and the second mold body 2. The cutting mounting positions 11 are used to install cutting components 5 respectively, so that the corresponding cutting component 5 can be selected and installed on the corresponding cutting mounting position 11 according to the cutting shape requirements of the material 7. Multiple pressing components 4 are provided, and the pressing components 4 can be detachably installed on the pressing mounting positions 12. The connection can be, but is not limited to, threaded connection, snap-fit ​​connection or magnetic connection. The pressing mounting positions 12 are used to install pressing components 4 respectively, so that the corresponding pressing component 4 can be selected and installed on the corresponding pressing mounting position 12 according to the installation requirements of the cutting component 5. The cutting mounting positions 11 and pressing mounting positions 12 are set one-to-one to facilitate the one-to-one matching use of the cutting component 5 and the pressing component 4.

[0068] See Figure 2-3 In some embodiments, the cutting assembly 5 includes a first cutter 51 with a wavy cutting edge. This means the first cutter 51 can cut the material 7's discharge edge into a wavy shape. For the same required length, compared to a straight edge, cutting the material 7's discharge plate into a wavy shape reduces the material 7's step distance, allowing for the production of material 7 with less material. It also provides a longer pressing length for the pressing assembly 4. The first cutter 51 is positioned at the material 7 output position of the first mold body 1 and the second mold body 2, so that the conveying assembly 3 supports the uncut portion of the material 7, providing rear support in the material 7's conveying direction. The first pressing member 41 can be located on the same side as the conveying assembly 3 and the first pressing member 41, so that during wavy discharge, the conveying assembly 3 and the first pressing member 41 can clamp the uncut portion of the material 7 from both sides, reducing the curling of the material 7 during wavy discharge.

[0069] See Figure 2 and Figure 5 In some embodiments, the cutting assembly 5 includes a second cutter 52, the cutting edge of which is configured as an arc, that is, the second cutter 52 can cut the material 7's dropping edge into a straight edge. The second cutter 52 is set at the material 7 input position of the first mold body 1 and the second mold body 2 so that the conveying assembly 3 mainly supports the cut part of the material 7 and provides front support in the conveying direction of the material 7. The second pressing member 42 can be located on the same side of the second cutter 52 as the conveying assembly 3, or the second pressing member 42 can be set on both sides of the second cutter 52 so that when the material is dropped with a straight edge, the conveying assembly 3 and the second pressing member 42 can clamp the cut part of the material 7 on both sides to reduce the deformation of the material 7 when the material is dropped with a straight edge.

[0070] The first cutter 51 and the second cutter 52 can be installed on different cutting mounting positions 11, so that the first cutter 51 and the second cutter 52 can perform different types of cutting on the material 7. Multiple cutting components 5 can share a set of blanking device, including the first mold body 1, the second mold body 2, the conveying component 3, and the pressing component 4, which can improve the versatility between blanking dies and reduce tooling investment costs. The first cutter 51 and the second cutter 52 can both include a punch 54 and a cutting edge 53. When the cutters are installed, one of the punch 54 and the cutting edge 53 is installed on the first mold body 1, and the other is installed on the second mold body 2. The cutting edge 53 and the punch 54 engage with each other to cut the material 7.

[0071] See Figure 6-7 In some embodiments, the pressing assembly 4 includes a first pressing member 41. The pressing mounting position 12 of the first pressing member 41 is correspondingly arranged with the cutting mounting position 11 of the first cutter 51. The first pressing member 41 is made of an elastic material, that is, the first pressing member 41 can be used when performing wavy material feeding. The elastic material can be, but is not limited to, polyurethane, silicone, or rubber, and can form an elastic abutment against the material 7. The side of the first pressing member 41 facing the first cutter 51 can be designed as a straight edge or a wavy shape with the same as the blade of the first cutter 51. The first pressing member 41 is set to fit the first cutter 51 so that the first pressing member 41 can perform targeted elastic abutment pressing at the cutting position of the material 7, making the pressing more stable and preventing deformation of the cutting edge of the material 7.

[0072] In this embodiment, the first pressing element 41 includes a plurality of pressing blocks 411, which are distributed along the length direction of the first cutter 51. A gap is provided between adjacent pressing blocks 411, and the distance of the gap can be selected as 2 mm. The gap is used to reduce the mutual compression deformation between the pressing blocks 411. That is, the plurality of pressing blocks 411 can elastically abut against the material 7 at different positions along the length direction of the first cutter 51. When the abutment force is large, the pressing blocks 411 can deform and expand in the circumferential direction. The gap can reduce the mutual compression stress when the pressing blocks 411 deform and expand, so that the pressing blocks 411 have sufficient deformation space, reduce stress concentration, and are low in cost and durable.

[0073] The first pressing block 411 may be, but is not limited to, square or prismatic. Optionally, each pressing block 411 may be 275 mm long and 25 mm wide at the bottom to allow for segmented pressing. The height difference between the pressing surface of the first pressing block 411 and the cutting edge 53 of the first tool 51 may be 5 mm.

[0074] See Figure 5In some embodiments, the pressing assembly 4 includes a second pressing member 42. The pressing mounting position 12 of the second pressing member 42 is correspondingly provided with the cutting mounting position 11 of the second cutter 52. That is, the second pressing member 42 can be used in conjunction with the second cutter 52 when performing straight edge cutting. The second pressing member 42 can be provided on one side of the second cutter 52 or on both sides of the second cutter 52, so as to provide elastic contact with the cutting position of the material 7.

[0075] The second pressing component 42 includes multiple nitrogen springs, which are arranged along the length of the second cutter 52. One end of the nitrogen spring is detachably connected to the first mold body 1, and the other end is used to abut against the material 7, so that the nitrogen spring can be installed on the first mold body 1 as needed. The nitrogen spring is small in size, has great elasticity, long stroke, stable operation, is precisely manufactured, has a long service life, and can squeeze the material 7 with great force.

[0076] Optionally, the second pressing component 42 may further include a pressing plate connected to a nitrogen spring, which can drive the pressing plate to elastically abut against the surface of the material 7. The material of the pressing plate may be, but is not limited to, an elastic material, such as polyurethane, rubber, or silicone. One or two pressing plates may be provided, and the pressing plates may be disposed on one side or both sides of the second cutter 52.

[0077] See Figure 2-3 In some embodiments, the conveying assembly 3 includes a support plate 31, which is mounted on the second mold 2 to provide elastic support for the surface of the material 7. That is, the support plate 31 can be positioned below the material 7 to provide a wide range of elastic support for the surface of the material 7, which can make the conveying process of the material 7 more stable and flat, and can also reduce the rigid contact between the material 7 and the second mold 2, thereby reducing damage to the material 7.

[0078] See Figure 3-5 In some embodiments, at least two support plates 31 are provided along the second direction to allow the support plates 31 to provide elastic support at different positions on the second mold body 2. The connection between the support plate 31 and the second mold body 2 is a detachable connection, which may be, but is not limited to, bolted, snap-fit, or magnetic connection, so that the support plate 31 can be installed and removed as needed. At least one support plate 31 is provided between the cutting mounting positions 11 of adjacent cutting components 5, so that the support plate 31 can provide elastic support at least in adjacent cutting components 5. The support plate 31 can be provided at the cutting mounting position 11 where no cutting component 5 is installed, so as to increase the support area for the material 7.

[0079] For example, when the cutting edge is configured as a wave shape, the first cutting tool 51 is installed between the first mold body 1 and the second mold body 2, the first pressing component 41 is installed on the first mold body 1, and the support plate 31 can be installed between the cutting mounting position 11 of the first cutting tool 51 and the cutting mounting position 11 of the second cutting tool 52 on the second mold body 2, as well as on the cutting mounting position 11 of the second cutting tool 52, so as to support the material 7 over a large area. The material 7 can be elastically clamped on both sides by the first pressing component 41 and the support plate 31. The first cutting tool 51 cuts the material 7 to obtain a finished product with a wave-shaped side. When the cutting edge is configured as an arc, the first cutting tool 51 and the first pressure plate can be disassembled, and the second cutting tool 52 can be installed between the first mold body 1 and the second mold body 2. The second pressure plate can be installed on the first mold body 1. The support plate 31 can be installed between the cutting mounting position 11 of the first cutting tool 51 and the cutting mounting position 11 of the second cutting tool 52 on the second mold body 2, as well as on the cutting mounting position 11 of the first cutting tool 51. It can also support the material 7 over a large area. The material 7 can be elastically clamped on both sides by the second pressure plate and the support plate 31. The second cutting tool 52 cuts the material 7 to obtain a finished product with straight sides.

[0080] In some embodiments, the support plate 31 is made of an elastic material, which may be, but is not limited to, polyurethane, polyvinyl chloride, rubber, or silicone, to improve the elastic contact performance of the support plate 31 with the material 7. The support plate 31 is configured as a brush plate, with the bristle ends of the support plate 31 in contact with the material 7. When the bristle ends of the brush plate slide relative to the surface of the material 7, a flexible contact can be formed, reducing scratches on the material 7. Moreover, a receiving gap can be formed between the bristles of the support plate 31. When dirt or impurities appear, they will fall into the receiving gaps between the bristles, thereby reducing damage to the material 7.

[0081] In this embodiment, the brush plate may include multiple sets of bristle bundles, the spacing between adjacent bristle bundles may be selected as 20 mm × 20 mm, each set of bristle bundles may consist of 10 to 15 bristle filaments, and the load-bearing capacity of each set of bristle bundles may be greater than or equal to 50 kg / m².

[0082] See Figure 3-4In some embodiments, the conveying assembly 3 further includes a guiding mechanism 32, which is disposed on the second mold body 2. The guiding mechanism 32 is used to reduce the directional deviation of the material 7 during conveying. The guiding mechanism 32 includes a first slider 321, a second slider 322, and a driving mechanism 323. The first slider 321 is disposed on one side of the support plate 31 on the second mold body 2, and the second slider 322 is disposed on the other side of the support plate 31 on the second mold body 2. That is, the first slider 321 and the second slider 322 can be located on both sides of the material 7 in the vertical direction of the material 7 conveying direction. The height of the top of the first slider 321 and the second slider 322 is higher than the height of the top of the support plate 31, so as to limit the conveying direction of the material 7 located on the support plate 31, thereby reducing the directional deviation of the material 7 during conveying. The drive mechanism 323 is connected to the first slider 321 and the second slider 322 respectively to drive the first slider 321 and the second slider 322 to move closer or further apart, thereby adjusting the distance between the first slider 321 and the second slider 322 to accommodate materials 7 of different widths. It also makes the first slider 321 and the material 7, as well as the second slider 322 and the material 7, fit more closely, making the limiting of the material 7 more accurate, ensuring the stability of the feeding direction, and keeping the material 7 centered during production.

[0083] In some embodiments, at least two first sliders 321 and second sliders 322 are respectively provided along the second direction, which can limit the material 7 at different positions on both sides of the material 7 along the conveying direction of the material 7, thereby increasing the blocking length of the material 7 and making the conveying of the material 7 more accurate and stable. The support plate 31 is provided with multiple receiving slots, which are respectively provided corresponding to the positions of the first slider 321 and the second slider 322. The receiving slots are used for the first slider 321 and the second slider 322 to move in or out, thereby reducing positional interference between the support plate 31 and the first slider 321 and the second slider 322, and increasing the supporting range of the support plate 31 for the material 7.

[0084] It should be noted that the receiving groove is mainly used to allow the first slider 321 and the second slider 322 to make way for each other. When there is one support plate 31, the receiving groove can be opened on the support plate 31. When there are multiple support plates 31, there can be a gap between adjacent support plates 31 to form the receiving groove.

[0085] See Figure 3-4In some embodiments, the drive mechanism 323 includes a lead screw 3231 and a drive member 3232. The lead screw 3231 is arranged perpendicularly to the conveying direction of the material 7, i.e., the width direction of the material 7. The lead screw 3231 includes a first threaded section 3231a and a second threaded section 3231b arranged along its own axial direction. A first slider 321 is threadedly connected to the first threaded section 3231a so that the first slider 321 can move along the axial direction of the lead screw 3231. A second slider 322 is threadedly connected to the second threaded section 3231b so that the second slider 322 can move along the axial direction of the lead screw 3231. The threads of the first threaded section 3231a and the second threaded section 3231b have opposite directions of rotation so that the movement directions of the first slider 321 and the second slider 322 are opposite. Multiple lead screws 3231 are arranged along a second direction so that they can be used in conjunction with multiple sets of first sliders 321 and second sliders 322 to form multiple sets of drives. The drive component 3232 is provided with multiple drive ends, each of which is correspondingly positioned with and connected to the lead screw 3231. This means that multiple drive ends can be driven by the same drive component 3232, facilitating synchronous movement. The drive component 3232 drives each lead screw 3231 to move synchronously, causing the first slider 321 and the second slider 322 to move closer or further apart, thus adjusting the distance between them. The structure is simple and easy to use, maintaining the synchronicity of movement between multiple sets of first sliders 321 and second sliders 322. Furthermore, the cooperation between the lead screw 3231 and the drive component 3232 ensures more accurate distance adjustment.

[0086] In this embodiment, the driving component 3232 can be, but is not limited to, a motor, a rotary cylinder, or a rotary hydraulic cylinder, as long as it can drive the lead screw 3231 to move in the forward or reverse direction. The transmission between multiple driving ends can be, but is not limited to, chain drive 32322, belt drive, or gear drive. Of course, the driving component 3232 can also be manually driven. For example, the driving component 3232 may include a sprocket 32321, a chain 32322, and a handwheel 32323. The sprocket 32321 is fixedly mounted on the lead screw 3231. The driving end can be configured as a sprocket 32321. Multiple sprockets 32321 can be provided, with each sprocket 32321 corresponding to a lead screw 3231. The chain 32322 connects adjacent sprockets 32321 to drive adjacent sprockets 32321 to rotate synchronously. The handwheel 32323 can be fixedly installed on any lead screw 3231. External force drives the handwheel 32323 to rotate, which in turn drives the corresponding lead screw 3231 to rotate. The lead screw 3231 drives other lead screws 3231 to rotate synchronously through the chain 32322 and the sprocket 32321, making the drive convenient.

[0087] See Figure 3-4The drive mechanism 323 further includes a guide rail 3233, which is arranged along the axial direction of the lead screw 3231. Both the first slider 321 and the second slider 322 can be slidably connected to the guide rail 3233 to limit and guide their movement. The drive mechanism 323 may also include a stop block 3234, which can be disposed on the lead screw 3231 and located between the first threaded section 3231a and the second threaded section 3231b, to prevent excessive movement of the first slider 321 and the second slider 322, thus avoiding damage to the lead screw 3231 and the threads. The drive mechanism 323 may also include a measuring scale, which is arranged along the axial direction of the lead screw 3231 to measure the real-time position and distance between the first slider 321 and the second slider 322, allowing for adjustments as needed.

[0088] See Figure 3 In some embodiments, the feeding device further includes an introduction mechanism 6, which is disposed on the second mold 2. The introduction mechanism 6 is used to introduce the material 7 onto the conveying assembly 3 so as to reduce the contact between the material 7 and the second mold 2 during the input process and reduce the damage to the material 7.

[0089] In this embodiment, the introducing mechanism 6 may include multiple wheel sets, each wheel set being arranged along a second direction. Each wheel set includes a bracket and multiple rollers, all of which are rotatably connected to the bracket. The rollers contact the surface of the material 7 to form rolling support, reducing scratches on the material 7. Optionally, six wheel sets may be provided.

[0090] The introduction mechanism 6 may also include lifting components. Multiple lifting components may be provided, each of which can be connected to a wheel set in a one-to-one correspondence. Alternatively, one lifting component may be provided, and multiple wheel sets can be installed on the lifting component, with the height position adjusted by the same lifting component. The lifting component may be, but is not limited to, a telescopic rod or a lifting platform, as long as it can drive the wheel sets to rise and fall.

[0091] See Figure 1-6 Another embodiment of this application provides a blanking processing method, which, based on the above-described blanking device, includes:

[0092] The cutting assembly 5 is installed between the first mold body 1 and the second mold body 2 so that the cutting assembly 5 can perform cutting operations on the material 7.

[0093] The pressing assembly 4 is installed on the first mold 1, and the conveying assembly 3 is installed on the second mold 2, so that the pressing assembly 4 and the conveying assembly 3 are respectively located on two opposite surfaces of the material 7.

[0094] The first mold 1 and the second mold 2 are driven to move closer or further apart from each other along the first direction, so that the pressing component 4 and the conveying component 3 respectively elastically abut against the surface of the material 7, forming a double-sided elastic clamping of the material 7, and the cutting component 5 cuts the material 7.

[0095] With this configuration, the blanking processing method of this embodiment can perform double-sided elastic clamping of the material 7 during the conveying and processing of the material 7, so that the pressing action is accurate and stable, and also reduces the rigid contact between the material 7 and the first mold body 1 and the second mold body 2, reducing scratches or abrasions on the material 7, and improving the quality of the finished product after blanking.

[0096] In some embodiments, the cutting assembly 5 is installed between the first mold 1 and the second mold 2, including:

[0097] Multiple cutting components 5 are provided, and each cutting component 5 corresponds to a different cutting edge. That is, cutting components 5 of multiple cutting types can share a set of blanking device, which improves the versatility between blanking dies.

[0098] Based on the required cutting edge, select one of the multiple cutting components 5 and denote it as the working cutting component 5;

[0099] The working cutting component 5 is installed between the first mold body 1 and the second mold body 2. That is, the corresponding working cutting component 5 can be selected and installed according to the blanking shape requirements of the product.

[0100] Based on the installation position of the working cutting component 5, the pressing component 4 and the conveying component 3 are installed in corresponding positions. That is, the cutting component 5 and the pressing component 4 are used in conjunction. When a certain cutting component 5 is selected as the working cutting component 5, the matching pressing component 4 needs to be installed at the corresponding pressing installation position 12. The conveying component 3 can also be adjusted in position according to the installation of the cutting component 5 to facilitate the cutting of different types of materials 7. Among the multiple cutting components 5, all cutting components 5 except the working cutting component 5 are kept in a disassembled state. That is, only one cutting component 5 is selected for installation for each cut, reducing cutting interference between different cutting components 5. The corresponding cutting installation position 11 of the disassembled cutting component 5 can be used for the installation of the conveying component 3, increasing the support area for the material 7 and making the conveying more stable.

[0101] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0102] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
