Description

Technical Field

[0001] This invention relates to the field of mold technology, and more specifically to a continuous cutting mold and a continuous cutting method that involves alternating blanking, positioning, and cutting. Background Technology

[0002] A progressive die is a die in which a press performs multiple processes simultaneously at several different stations in a single stroke. The blanked part is gradually formed in the progressive die, which can combine multiple processes such as trimming, notching, grooving, punching, plastic deformation, and blanking into a single die. Progressive dies typically use guide pins for positioning or side-edge positioning for spacing. Guide pins achieve positional calibration through precision positioning holes, while side-edges ensure feeding accuracy by cutting off the material edge to form a step distance limiting shoulder. These dies also possess composite processing capabilities such as blanking, bending, and deep drawing, and can achieve automated continuous feeding through an automatic feed stop device. In practice, existing progressive dies still have certain limitations. Their machining accuracy is greatly affected by the cumulative error of multiple stations. As progressive dies have a large number of stations, the positioning accuracy is affected by factors such as feeding error, die manufacturing error and material deformation during the stamping process when the strip is moved step by step between stations. This cumulative effect ultimately affects the dimensional consistency of the finished product. Especially in multi-step progressive dies for high-speed stamping, if only the side blade is used as the strip positioning device, it is difficult to guarantee the feeding accuracy. This is because the strip itself has cutting shape and size errors, and it is difficult to ensure that the two sides are parallel.

[0003] Meanwhile, the positioning connection between the punching and cutting processes in existing progressive dies is not reliable enough. When performing punching or cutting operations, existing progressive dies usually only set up a positioning mechanism at the station entrance to position the strip once. There is a lack of continuous positioning compensation in subsequent processes. When the strip is subjected to large punching or cutting forces, it is easy to shift or warp, which will cause the processing datum of subsequent processes to deviate and affect product quality. At the same time, the same station of existing progressive dies cannot meet the timing coordination requirements of punching, positioning and cutting functions simultaneously. In the limited station space of progressive dies, if punching, positioning and cutting are to be completed in the same position, each functional component needs to operate in a strict sequence and without interference during the die's descent. The dies of traditional progressive dies are mostly fixed structures, which cannot actively move aside after punching, which can easily hinder the insertion of subsequent positioning pins or the cutting action of the tool, limiting the further centralization of the process. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that existing continuous molds have certain limitations. They have a large number of stations and lack continuous positioning compensation in subsequent processes, resulting in large cumulative errors when continuously forming. They also cannot meet the timing coordination requirements of multiple forming operations such as punching, positioning and cutting at the same station, resulting in low forming efficiency and high mold design and manufacturing costs.

[0005] To solve the above-mentioned technical problems, the first aspect of the present invention adopts the following technical solution: a continuous cutting die for alternating blanking, positioning and cutting, including an upper die plate, a lower die plate and a die base, wherein the upper die plate and the lower die plate are both mounted on the die base, the upper die plate is provided with a plurality of first forming components, the plurality of first forming components extending along the conveying direction of the material strip, the lower die plate is provided with second forming components corresponding one-to-one with the plurality of first forming components, the plurality of first forming components cooperate with their respective corresponding second forming components to complete the corresponding forming work when moving to a preset processing stroke in a single working cycle, and the plurality of sets of first forming components and second forming components cooperate with each other in a single working cycle to complete their respective corresponding forming work.

[0006] In operation, this invention integrates multiple different forming processes on different parts of the material strip by extending and arranging multiple sets of first forming components and second forming components along the material strip conveying direction in a single work cycle. This significantly reduces the transfer error of the material strip between processes. At the same time, through the cooperation of several sets of first forming components and second forming components, different forming processes are completed at different processing strokes in a single work cycle. This concentrates multiple forming processes in the same station, enabling the sequential completion of multiple forming processes in a single work cycle. This effectively improves the forming efficiency of continuous cutting dies, resulting in high integration and good forming effect.

[0007] Preferably, the positioning strokes of several sets of first forming components and second forming components overlap, the punching strokes of several sets of first forming components and second forming components are staggered, and when some of the first forming components and second forming components are performing cutting work, at least one set of first forming components and second forming components is performing positioning work.

[0008] In operation, this invention achieves continuous positioning of the strip during the work cycle through overlapping positioning strokes, preventing the strip from shifting or warping due to forming operations. Continuous positioning compensation effectively reduces the cumulative error of continuous forming operations, ensuring high forming accuracy of the finished product. Furthermore, the staggered arrangement of the punching strokes avoids multiple simultaneous punching operations, reducing the maximum impact load on the continuous cutting die and minimizing instantaneous vibration, thereby effectively improving the service life of the continuous cutting die. By setting at least one set of first forming components and second forming components for positioning during punching or cutting operations, the strip remains accurately positioned under punching or cutting forces, preventing shifting or warping due to these forces and ensuring the forming quality of the finished product.

[0009] Preferably, when a plurality of first forming components and second forming components are performing punching or cutting operations, at least two sets of first forming components and second forming components are performing positioning operations, with the first forming components and second forming components performing punching or cutting operations arranged between the first forming components and second forming components performing positioning operations.

[0010] Preferably, the first forming component is provided with a first punching part, a first positioning part, and a first cutting part connected as an integral unit from bottom to top. When the upper template moves downward to a preset processing stroke, the first punching part cooperates with the corresponding second forming component to punch out a positioning part on the strip for cooperating with the first positioning part. When the upper template moves downward to the preset processing stroke, the first positioning part cooperates with the corresponding positioning part to achieve positioning of the strip. After positioning the strip, the first cutting part performs cutting work on the strip when the upper template moves downward to the end of the processing stroke.

[0011] Preferably, the second forming component is provided with a first punching engagement part for cooperating with the first punching part to complete the punching work, and a first engagement adjustment device for driving the first punching engagement part to move to make room for the first positioning part and the first cutting part. The first punching engagement part is vertically mounted in the lower template and is connected to the output part of the first engagement adjustment device. The first punching engagement part is aligned with the first punching part and cooperates with the first punching part to complete the punching work on the strip when the upper template moves downward to the preset processing stroke. After completing the punching work, the first punching engagement part moves downward under the drive of the first engagement adjustment device to make room for the first positioning part and the first cutting part to move.

[0012] Preferably, the first punching part is provided with a first mating hole for cooperating with the first punching part, and the first punching part is limited and installed in the first mating hole when the upper template moves downward to the end of the processing stroke after completing the punching work.

[0013] In operation, this invention enables sequential punching, positioning, and cutting operations within the same workstation by setting first punching sections, first positioning sections, and first cutting sections at different heights. No additional driving device is required, allowing for precise process switching. The structure is compact and highly reliable. Furthermore, a first punching mating section works in conjunction with the first punching section, providing precise guidance to the first forming component as it descends, ensuring straightness during descent and further improving the forming accuracy of subsequent forming operations. A first mating adjustment device actively lowers the first punching mating section, freeing up working space for the first positioning and first cutting sections, and enabling chip collection and discharge, preventing chip contamination of the first punching mating section and ensuring the forming quality of the punching operation.

[0014] Preferably, the first forming component further includes a fourth positioning part, which is eccentrically arranged with the first punching part, the first positioning part and the first cutting part. Before the first punching part performs the punching operation, the fourth positioning part cooperates with the corresponding positioning part on the strip to achieve positioning of the strip.

[0015] When the present invention is in operation, the fourth positioning part cooperates with the corresponding positioning part on the strip before the blanking work begins to achieve the pre-positioning of the strip, thereby guiding the strip to the correct forming station. This can eliminate the cumulative error of the strip in the step feed and ensure that the subsequent first blanking part can blank the corresponding forming part at the precise position, which can greatly improve the positioning reference accuracy of the whole process.

[0016] Preferably, the first forming component includes a guide part and a cutting part. The guide part is connected to the material belt drive when the upper template moves downward to a preset processing stroke, and drives the material belt to a preset cutting position. The cutting part cuts the material belt when it moves to the cutting position to realize the finished product output.

[0017] To solve the above-mentioned technical problems, the second aspect of the present invention adopts the following technical solution: a continuous cutting method for alternating blanking, positioning, and cutting, using a continuous cutting die for alternating blanking, positioning, and cutting as described in any of the preceding aspects, comprising the following steps:

[0018] The material is fed into the conveyor belt in sequence according to the preset step distance;

[0019] According to the preset process flow, punching, positioning and / or cutting work is carried out on different parts of the strip, and punching, positioning or cutting work is carried out on the strip according to the preset work stroke in a single work cycle until the finished product is formed.

[0020] The finished product is transferred to the preset cutting station, where it is cut from the conveyor belt to complete the product discharge.

[0021] Preferably, the method also includes the following step: positioning both sides of the corresponding part when punching or cutting the corresponding part of the strip.

[0022] The beneficial technical effects of this invention include:

[0023] 1. This invention integrates multiple different forming processes on different parts of the material strip in a single work cycle by extending and arranging multiple sets of first forming components and second forming components along the material strip conveying direction. This significantly reduces the transfer error of the material strip between processes. At the same time, through the mutual cooperation of several sets of first forming components and second forming components, different forming processes are completed at different processing strokes in a single work cycle. This concentrates multiple forming processes in the same station and enables the sequential completion of multiple forming processes in a single work cycle, thereby effectively improving the forming efficiency of continuous cutting molds. It has a high degree of integration and good forming effect.

[0024] 2. This invention achieves continuous positioning of the strip during the work cycle through the overlapping arrangement of positioning strokes, preventing the strip from shifting or warping due to forming operations. Continuous positioning compensation effectively reduces the cumulative error of continuous forming operations, ensuring high forming accuracy of the finished product. Furthermore, the staggered arrangement of punching strokes avoids multiple simultaneous punching operations, reducing the maximum impact load on the continuous cutting die and minimizing instantaneous vibration, thereby effectively improving the service life of the continuous cutting die. By setting at least one set of first forming components and second forming components for positioning during punching or cutting operations, the strip remains accurately positioned under punching or cutting forces, preventing shifting or warping due to these forces and ensuring the forming quality of the finished product.

[0025] 3. This invention enables punching, positioning, and cutting operations to be performed sequentially within the same workstation by setting a first punching section, a first positioning section, and a first cutting section at different heights. No additional driving device is required, allowing for precise process switching. The structure is compact and highly reliable. Furthermore, the first punching mating section works in conjunction with the first punching section, providing precise guidance to the first forming component as it descends, ensuring straightness during descent and further improving the forming accuracy of subsequent forming operations. The first mating adjustment device actively lowers the first punching mating section, freeing up working space for the first positioning section and the first cutting section, and enabling chip collection and discharge, preventing chip contamination of the first punching mating section and ensuring the forming quality of the punching operation.

[0026] 4. The present invention achieves the pre-positioning of the material strip by having the fourth positioning part cooperate with the corresponding positioning part on the strip before the blanking operation begins, thereby guiding the strip to the correct forming station. This can eliminate the cumulative error of the strip during the step feed and ensure that the subsequent first blanking part can blank the corresponding forming part at the precise position, which can greatly improve the positioning reference accuracy of the entire process.

[0035] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0036] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” are used only to indicate orientation or positional relationship for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0037] Example 1:

[0038] Please see Figures 1 to 6 This embodiment discloses a continuous cutting die with alternating punching and positioning cutting, including an upper die plate 1, a lower die plate 2, and a die base 3. The following is a detailed description in conjunction with the accompanying drawings.

[0039] In this embodiment, both the upper template 1 and the lower template 2 are mounted on the mold base 3. The upper template 1 is provided with a plurality of first forming components 11, which extend along the conveying direction of the material strip. The lower template 2 is provided with a second forming component 21 corresponding to each of the plurality of first forming components 11. The plurality of first forming components 11 cooperate with their respective corresponding second forming components 21 to complete the corresponding forming work when they move to the preset processing stroke in a single working cycle. The plurality of first forming components 11 and second forming components 21 cooperate with each other in a single working cycle to complete their respective forming work.

[0040] In this embodiment, by extending and arranging multiple sets of first forming components 11 and second forming components 21 along the conveying direction of the material strip, multiple different forming processes on different parts of the material strip can be integrated in a single work cycle, thereby significantly reducing the transfer error of the material strip between processes. At the same time, through the mutual cooperation of several sets of first forming components 11 and second forming components 21, different forming processes are completed to different processing strokes in a single work cycle, thereby concentrating multiple forming processes in the same station. Multiple forming processes can be completed in a single work cycle, thereby effectively improving the forming efficiency of continuous cutting molds, with high integration and good forming effect.

[0041] In specific implementation, the positioning strokes of several groups of first forming components 11 and second forming components 21 overlap, the punching strokes of several groups of first forming components 11 and second forming components 21 are staggered, and when one of the several groups of first forming components 11 and second forming components 21 is performing cutting work, at least one group of first forming components 11 and second forming components 21 is performing positioning work.

[0042] In this embodiment, the overlapping arrangement of positioning strokes achieves continuous positioning of the strip during the work cycle, preventing the strip from shifting or warping due to the forming process. Continuous positioning compensation effectively reduces the cumulative error of continuous forming, ensuring high forming accuracy of the finished product. The staggered arrangement of punching strokes avoids multiple simultaneous punching operations, reducing the maximum impact load on the continuous cutting die and minimizing instantaneous vibration, thereby effectively improving the service life of the continuous cutting die. Furthermore, by setting at least one set of first forming components 11 and second forming components 21 for positioning during punching or cutting operations, the strip remains accurately positioned under punching or cutting forces, preventing shifting or warping due to these forces and ensuring the forming quality of the finished product.

[0043] To further improve the forming effect, when the first forming components 11 and the second forming components 21 are performing punching or cutting operations, at least two sets of the first forming components 11 and the second forming components 21 are performing positioning operations. The first forming components 11 and the second forming components 21 performing punching or cutting operations are arranged between the first forming components 11 and the second forming components 21 performing positioning operations. During operation, the punching station or cutting station is arranged between at least two sets of components performing positioning operations, which is equivalent to forming clamping points on the front and rear sides of the punching or cutting part. This greatly enhances the local rigidity of the strip in the punching or cutting area, and can effectively suppress the vibration and burrs generated during the punching or cutting process. It is especially suitable for the precision machining of thin-walled strips or high-hardness materials.

[0044] Example 2:

[0045] Please see Figures 1 to 6 This embodiment provides a continuous cutting die with alternating punching and positioning cutting. The similarities with other embodiments will not be repeated here. The differences will be described in detail below.

[0046] In this embodiment, the first forming component 11 is provided with a first punching part 1101, a first positioning part 1102 and a first cutting part 1103 connected together from bottom to top. When the upper template 1 moves downward to a preset processing stroke, the first punching part 1101 cooperates with the corresponding second forming component 21 to punch out a positioning part on the strip for cooperating with the first positioning part 1102. When the upper template 1 moves downward to the preset processing stroke, the first positioning part 1102 cooperates with the corresponding positioning part to achieve positioning of the strip. After positioning the strip, the first cutting part 1103 performs cutting work on the strip when the upper template 1 moves downward to the end of the processing stroke.

[0047] Preferably, the second forming component 21 is provided with a first punching engagement part 211 for cooperating with the first punching part 1101 to complete the punching work, and a first engagement adjustment device 212 for driving the first punching engagement part 211 to move to make room for the first positioning part 1102 and the first cutting part 1103. The first punching engagement part 211 is vertically mounted in the lower template 2 and is connected to the output part of the first engagement adjustment device 212. The first punching engagement part 211 is aligned with the first punching part 1101 and cooperates with the first punching part 1101 to complete the punching work on the strip when the upper template 1 moves downward to the preset processing stroke. After completing the punching work, the first punching engagement part 211 moves downward under the drive of the first engagement adjustment device 212 to make room for the first positioning part 1102 and the first cutting part 1103 to move.

[0048] In specific implementation, in order to further improve the stability of the first forming component 11 during operation, the first punching mating part 211 is provided with a first mating hole 2111 for cooperating with the first punching part 1101. After the first punching part 1101 completes the punching work, it is limited and installed in the first mating hole 2111 when the upper template 1 moves downward to the end of the processing stroke.

[0049] In this embodiment, by setting the first blanking section 1101, the first positioning section 1102, and the first cutting section 1103 at different heights, blanking, positioning, and cutting operations can be performed sequentially in the same workstation. No additional driving device is required, enabling precise process switching. The structure is compact and highly reliable. At the same time, the first blanking mating section 211 cooperates with the first blanking section 1101, which can provide precise guidance for the first forming component 11 when it moves downward, ensuring the straightness of the first forming component 11 during descent. This can further improve the forming accuracy of subsequent forming operations. Furthermore, by setting the first mating adjustment device 212 to drive the first blanking mating section 211 to descend actively, working space can be freed up for the first positioning section 1102 and the first cutting section 1103. It can also collect and discharge chips, preventing chip contamination of the first blanking mating section 211 and ensuring the forming quality of the blanking operation.

[0050] Preferably, the first forming component 11 further includes a fourth positioning part 1110. The fourth positioning part 1110 is eccentrically arranged with the first punching part 1101, the first positioning part 1102 and the first cutting part 1103. Before the first punching part 1101 performs the punching operation, the fourth positioning part 1110 cooperates with the corresponding positioning part on the strip to achieve positioning of the strip.

[0051] In this embodiment, the fourth positioning part 1110 cooperates with the corresponding positioning part on the strip before the blanking work begins to achieve the pre-positioning of the strip, thereby guiding the strip to the correct forming station. This can eliminate the cumulative error of the strip in the step feed and ensure that the subsequent first blanking part 1101 can blank the corresponding forming part at the precise position, which can greatly improve the positioning reference accuracy of the whole process.

[0052] Example 3:

[0053] Please see Figures 1 to 6 This embodiment provides a continuous cutting die with alternating punching and positioning cutting. The similarities with other embodiments will not be repeated here. The differences will be described in detail below.

[0054] In this embodiment, in order to reduce the design pressure of several molding components and reduce the connection difficulty in the design of each molding work, the punching part, positioning part and cutting part of the first molding component 11 can be arranged in a custom order according to the actual processing requirements. For example, the first molding component 11 can be provided with a second punching part 1104, a second cutting part 1106 and a second positioning part 1105 connected together from bottom to top, or the first molding component 11 can be provided with a third positioning part 1108, a third punching part 1107 and a third cutting part 1109 connected together from bottom to top, or only the punching part and positioning part, the punching part and cutting part or the positioning part and cutting part are provided, so as to achieve the design goal of the molding work station.

[0055] Of course, different forming parts can be set according to different forming operations. For example, a bending part 1113 can be set to achieve the bending of the material strip. To achieve the unloading of the finished product, the first forming component 11 can include a guide part 1111 and a cutting part 1112. The guide part 1111 is connected to the material strip drive when the upper template 1 moves downward to the preset processing stroke, and drives the material strip to the preset cutting position. The cutting part 1112 cuts the material strip when the material strip moves to the cutting position to achieve the unloading of the finished product. In actual work, any suitable first forming component 11 can be selected according to different forming requirements, and a matching second forming component 21 can be selected according to the usage requirements.

[0056] In practical implementation, the cutting part of the first forming component 11 can be cut from the inside out or from the outside in according to actual needs, and can form a forming part that matches the design standard. In operation, it is necessary to first perform the cutting work from the inside out to form a precise inner positioning hole. The inner positioning hole and the fourth positioning part 1110 can be precisely matched to effectively improve the positioning accuracy of the strip and avoid the strip from being skewed. Thus, the forming accuracy can be effectively improved when the cutting work from the outside in is performed.

[0057] Example 4:

[0058] This embodiment provides a continuous cutting method using alternating blanking and positioning cutting. The continuous cutting die using alternating blanking and positioning cutting as described in any of the above embodiments includes the following steps:

[0059] The material is fed into the conveyor belt in sequence according to the preset step distance;

[0060] According to the preset process flow, punching, positioning and / or cutting work is carried out on different parts of the strip, and punching, positioning or cutting work is carried out on the strip according to the preset work stroke in a single work cycle until the finished product is formed.

[0061] The finished product is transferred to the preset cutting station, where it is cut from the conveyor belt to complete the product discharge.

[0062] When this embodiment is working, it can realize a series of tasks such as step feeding, punching / positioning / cutting according to the preset process flow, transferring finished products and cutting the material strip to realize finished product unloading. It can decompose the complex forming process into an orderly cycle, which can ensure that all stations work synchronously and without waiting for each other in a single work cycle, maximize the use of the time window of the mold descent, and thus achieve efficient production line.

[0063] Preferably, the method also includes the following steps: when performing punching or cutting work on the corresponding part of the strip, positioning work is performed on both sides of the part. At the same time, during the operation, the stroke depth and timing of punching and cutting are flexibly adjusted according to the ductility and hardness of different materials of the strip. Through the extremely high process flexibility of the first forming component 11, the punching part, positioning part and cutting part can be flexibly combined, which can avoid mold wear caused by additional actions and also avoid idle strokes, thereby effectively improving forming efficiency.

[0064] The beneficial technical effects of this embodiment include: by extending and arranging multiple sets of first forming components and second forming components along the conveying direction of the material strip, the present invention can integrate multiple different forming processes on different parts of the material strip in a single working cycle, thereby significantly reducing the transfer error of the material strip between processes. At the same time, through the mutual cooperation of several sets of first forming components and second forming components, different forming processes are completed at different processing strokes in a single working cycle, thereby concentrating multiple forming processes in the same station. Multiple forming processes can be completed sequentially in a single working cycle, thereby effectively improving the forming efficiency of continuous cutting molds, with high integration and good forming effect.

[0065] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
