Technical Field
[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to a cutting device for metal sheets used in automotive parts. Background Technology
[0002] In the production of sheet metal for automotive parts, the cutting process is a crucial step. These sheets are widely used in manufacturing high-quality, high-performance automotive components due to their high strength and specific physical properties. However, this high strength also means that these sheets require special handling during processing, especially the cutting process.
[0003] In existing technologies, tools used for cutting such metal sheets are typically equipped with blades featuring flat cutting edges. While this design is simple and straightforward, it proves inadequate when dealing with high-strength metals. To achieve effective cutting, the operator must apply significant force to ensure the blade penetrates and cuts along a predetermined path. This cutting method not only increases the difficulty of the operation but also places higher demands on the equipment, potentially requiring a more powerful drive system to provide the necessary force. More importantly, when cutting with a blade featuring a flat cutting edge, the entire cutting surface simultaneously contacts the metal sheet, applying uniform pressure. For high-strength metal sheets, this large-area simultaneous pressure can lead to localized deformation of the material, especially at the initial stage of cutting, when the blade first enters the metal sheet. Since a stable kerf has not yet formed at this point, the pressure applied by the blade is more likely to cause bending or twisting of the metal sheet, affecting the dimensional accuracy and shape integrity of the final product. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a cutting device for metal sheets of automotive parts, in light of the current state of the technology.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A cutting device for metal sheets of automotive parts is proposed, comprising:
[0006] Workbench;
[0007] A fixing component having a fixing seat disposed on the workbench, the fixing seat having a cutout portion that fits the outer contour of a metal plate, the metal plate being inserted into the cutout portion;
[0008] The cutting assembly has a cutting member movably disposed on the side of the fixed base. One end of the cutting member is provided with a pointed head. The fixed base is provided with a cutting groove that penetrates the hollow part. The cutting member is pushed into the cutting groove to cut the metal plate. The pointed head can contact the metal plate first because the cutting member is cutting the metal plate, thereby reducing the contact area between the cutting member and the metal plate.
[0009] In the aforementioned cutting device for metal sheets of automotive parts, the fixing assembly further includes:
[0010] The fixing plate has a cavity on the fixing base, and the fixing plate is threaded to both sides of the cavity, and the fixing plate on both sides is provided with the hollow part;
[0011] A fixing strip is threaded between the fixing plates on both sides. The fixing strip is provided on both the upper and lower sides of the cavity, and the fixing strip and the fixing plate together form the cutting groove.
[0012] In the aforementioned cutting device for metal sheets of automotive parts, the cutting assembly further includes a driving member, with one end of the cutting member away from the fixed base connected to the output end of the driving member, and the driving member is used to drive the cutting member to move.
[0013] In the aforementioned cutting device for metal sheets of automotive parts, a support frame is also provided on the worktable, the fixed seat is provided on one side of the support frame, and the driving component is connected to the other side of the support frame.
[0014] In the aforementioned cutting device for metal sheets of automotive parts, the cutting element is provided with an inclined portion, and the inclined portion is provided on both sides of the pointed head. The inclined portion moves against the fixing strip to push the metal chips generated during the cutting of the metal sheet.
[0015] In the aforementioned cutting device for metal sheets of automotive parts, a chip removal groove is inclinedly provided on the fixed plate. The chip removal groove is located on the moving path of the inclined part and is used to collect the metal chips.
[0016] In the aforementioned cutting device for metal sheets of automotive parts, the support frame is provided with a chip discharge port, which is connected to the chip discharge groove for discharging the metal chips.
[0017] In the aforementioned cutting device for metal sheets of automotive parts, the output end of the drive component is provided with a connecting part, and the end of the cutting component away from the fixed base is threadedly connected to the connecting part.
[0018] In the above-mentioned cutting device for metal sheets of automotive parts, the output end of the drive component is provided with a moving rod, the support frame is provided with a guide groove, the moving rod is movably inserted into the guide groove, and the moving rod can move along the guide groove as the drive component drives the cutting component to move, so as to reflect the driving stroke of the drive component.
[0019] The support frame is also equipped with two detection elements, which are located on both sides of the guide groove. The detection elements are used to detect the stroke of the moving rod.
[0020] Compared with the prior art, the advantages of this utility model are as follows: by setting a pointed head on the cutting component, when the metal plate is inserted into the hollow part and reaches the preset length, the cutting component is activated, driving the cutting component to advance into the cutting groove to perform the cutting operation on the metal plate; during the cutting process, the pointed head on the cutting component first contacts the metal plate. Due to the small contact area of the pointed head, it can generate greater pressure under the same force conditions, thus cutting into the metal plate more easily. By concentrating the force on a small area to start the cutting, rather than applying it to a large area at once, excessive stress on the metal plate is avoided, further protecting the integrity and shape of the material; the fixing component provides additional stability to the metal plate, ensuring the straightness and accuracy during the cutting process, and improving the quality of the final product.

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0028] like Figures 1 to 5 As shown, this utility model discloses a cutting device for metal sheets of automotive parts, comprising: a worktable 1; a fixing component 2, which has a fixing seat 3 disposed on the worktable 1, the fixing seat 3 having a hollow part 4 that fits the outer contour of the metal sheet, the metal sheet being inserted into the hollow part 4; and a cutting component 5, which has a cutting element 6 movably disposed on the side of the fixing seat 3, one end of the cutting element 6 having a pointed head 7, the fixing seat 3 having a cutting groove 8 penetrating the hollow part 4, the cutting element 6 being pushed into the cutting groove 8 for cutting the metal sheet, the pointed head 7 being able to contact the metal sheet first due to the cutting element 6 cutting the metal sheet, thereby reducing the contact area between the cutting element 6 and the metal sheet.
[0029] After the metal sheet is formed, it is directly transported to the location of the cutting device in this solution. First, the metal sheet is accurately inserted into the hollow part 4 on the fixed base 3. The shape of the hollow part 4 is specially designed to fit the outer contour of the metal sheet. This design not only provides stable support for the metal sheet, but also ensures the positional accuracy of the metal sheet during the cutting process, preventing unnecessary movement or displacement. When the metal sheet is inserted into the hollow part 4 and reaches the preset length, the system automatically detects this state and stops the further insertion of the metal sheet. At this time, the cutting component 5 is activated, driving the cutting piece 6 to advance into the cutting groove 8 to perform the cutting operation on the metal sheet inserted in the hollow part 4. During the cutting process, the pointed head 7 on the cutting piece 6 first contacts the metal sheet. The design of the pointed tip 7 results in a smaller contact area with the metal plate, which generates greater pressure under the same applied force. This high pressure helps to cut into the metal plate more easily, thus effectively initiating the cutting process. Compared to traditional flat cutting blades, the pointed tip 7 can provide more concentrated force at the start of the cutting process, which is especially important for applications requiring precise and high-quality cutting edges. In addition, the design of the pointed tip 7 also takes into account the possibility of deformation of the metal plate at the start of the cutting process. By concentrating the force on a small area to start the cutting, rather than applying it to a large area all at once, it can avoid applying excessive stress to the metal plate, thereby protecting the material from damage. At the same time, the fixing component 2 provides additional stability to the metal plate, helping to maintain straightness and accuracy during the cutting process.
[0030] Specifically, the fixing component 2 also includes: a fixing plate 9, a fixing seat 3 having a cavity, and fixing plates 9 threadedly connected to both sides of the cavity, with cutouts 4 on both sides of the fixing plates 9. This threaded connection not only provides a stable mechanical connection but also allows the position of the fixing plates 9 to be adjusted as needed. The cutouts 4 precisely match the outer contour of the metal plate, allowing the metal plate to be firmly inserted without shaking or shifting. The design of the cutouts 4 takes into account the thickness and shape of the metal plate, ensuring that it can maintain the optimal position during the cutting process. The fixing strip 10 is firmly installed between the fixing plates 9 on both sides by a threaded connection, specifically located on the upper and lower sides of the cavity. The fixing strip 10 and the fixing plates 9 fit tightly together to form a precise cutting groove 8. The cutting groove 8 is designed to provide an accurate feeding path for the cutting part 6, ensuring stability and accuracy during the cutting process.
[0031] The specific cutting component also includes a drive unit 11. The end of the cutting component 6 away from the fixed base 3 is connected to the output end of the drive unit 11. When the cutting operation is started, the drive unit 11 starts to operate according to the preset program to push the cutting component 6 into the cutting groove 8. The drive unit 11 provides the necessary driving force. The drive unit 11 is preferably a hydraulic cylinder.
[0032] To optimize the spatial layout of the entire cutting device and enhance its structural stability, a support frame 12 is also installed on the workbench 1. The support frame 12 plays a key supporting role: on the one hand, the fixed seat 3 is firmly installed on one side of the support frame 12, providing a solid support platform for the metal plate; on the other hand, the drive component 11 is connected to the other side of the support frame 12, ensuring the directness and reliability of power transmission. This design not only makes the entire device more compact, but also facilitates maintenance and adjustment by operators.
[0033] In order to effectively clean up the metal shavings generated when cutting metal plates, the present invention has made special optimizations to the design of the cutting part 6. Specifically, inclined parts 13 are provided on both sides of the tip 7 of the cutting part 6. When the cutting part 6 is pushed into the cutting groove 8 and cuts the metal plate, the inclined parts 13 will maintain active contact with the fixing strip 10 and slide along the fixing strip 10. As the cutting part 6 is pushed forward, the inclined parts 13 not only help guide the movement direction of the cutting part 6, but also play a role in pushing away the metal shavings. The metal shavings generated during the cutting process are continuously pushed forward by the inclined parts 13.
[0034] To more effectively collect and remove metal chips generated during the cutting process, the fixing plate 9 is specially designed with inclined chip removal grooves 14. These chip removal grooves 14 are located on the moving path of the inclined part 13 of the cutting part 6, ensuring that during the cutting process, as the inclined part 13 slides along the fixing strip 10, the metal chips can be smoothly guided into the chip removal grooves 14. The design of the chip removal grooves 14 not only improves the collection efficiency of metal chips, but also prevents the accumulation of metal chips in the cutting area, thereby maintaining a clean cutting environment and reducing cutting quality problems caused by metal chip interference.
[0035] To further improve the removal of metal chips, a chip discharge port 15 is specially provided on the support frame 12. The chip discharge port 15 is connected to the chip discharge groove 14 on the fixed plate 9. The inclined design of the chip discharge groove 14 utilizes the gravity of the metal chips themselves, allowing them to slide naturally along the groove to the chip discharge port 15 and finally be smoothly discharged outside the device. This design not only simplifies the cleaning process of metal chips, but also effectively prevents equipment failures that may be caused by internal accumulation. The position of the chip discharge port 15 is carefully planned to ensure that the metal chips can be discharged smoothly without interfering with the cutting operation or the function of other components.
[0036] To facilitate the connection between the cutting component 6 and the driving component 11, the output end of the driving component 11 is provided with a dedicated connecting part 16. The end of the cutting component 6 away from the fixed base 3 is securely installed on this connecting part 16 by a threaded connection. This design allows the user to quickly and safely replace the cutting component 6 by simply loosening the threaded connection when the cutting component 6 ages due to long-term use or breaks due to improper operation, thereby ensuring the continuous and efficient operation of the equipment.
[0037] To achieve precise and stable movement of the cutting piece 6, a moving rod 17 is provided at the output end of the drive unit 11. A guide groove 18 is specially designed on the support frame 12 to accommodate and guide the movement of the moving rod 17. The moving rod 17 is movably inserted into the guide groove 18. When the drive unit 11 drives the cutting piece 6 to move, the moving rod 17 slides smoothly along the guide groove 18 under the action of the drive unit 11. This design ensures the smooth movement of the moving rod 17. The guide groove 18 provides a clear movement path for the moving rod 17, ensuring that it runs according to the predetermined trajectory. The design of the moving rod 17 is to reflect the driving stroke of the drive unit 11.
[0038] To further improve the safety and accuracy of the cutting process, two detection elements 19 are installed on the support frame 12, located on both sides of the guide groove 18. The main function of these detection elements 19 is to monitor the stroke of the moving rod 17 in real time to ensure that it moves within a predetermined range. Specifically, one detection element 19 is located at the initial end of the moving rod 17's path, and the other detection element 19 is located at the end of the moving rod 17's path. The two detection elements 19 together sense the positional change of the moving rod 17 and feed the data back to the control system. This allows the system to adjust the working parameters of the drive element 11 according to the actual stroke, ensuring the accuracy and consistency of the cutting operation. If the moving rod 17 is detected to exceed or fall below the preset stroke range, the detection element 19 will immediately trigger an alarm or automatically stop the action of the drive element 11 to prevent equipment damage or cutting errors caused by abnormal stroke. The detection element 19 is preferably a displacement sensor.
