Description

Technical Field

[0001] This application relates to the field of stamping feeding technology, and in particular to a stamping feeding device. Background Technology

[0002] In the stamping production of vehicle parts, the stamping feeding device is a crucial link in ensuring stamping efficiency and product quality. As the core component of the stamping feeding device, the performance of the feed roller directly affects the feeding accuracy and stability. Traditional feed rollers often use high-strength materials, and the friction between them and the sheet metal is improved through optimized surface treatment processes.

[0003] With the increasing use of aluminum sheets and other components in body-in-white, stamping feeding devices need to transport strips of different materials. In order to avoid cross-contamination and damage to the strips, different feeding rollers are required for different strips. However, traditional stamping feeding devices only have one type of feeding roller, so they can only transport strips of a single material. Utility Model Content

[0004] This application provides a stamping feeding device to solve the problem that traditional stamping feeding devices can only convey strips of a single material.

[0005] This application provides a stamping feeding device, including a lifting component and a plurality of conveying components arranged sequentially along a first direction; any one of the conveying components is used to convey a strip of one material, and different conveying components are used to convey strips of different materials;

[0006] The lifting component is used to drive the material belt that has passed over another conveying component to move in a direction opposite to a second direction when the material belt conveyed by any of the conveying components passes over another conveying component, the second direction being perpendicular to the first direction.

[0007] In some embodiments, the conveying assembly includes a first feed roller and a second feed roller, which are arranged sequentially along a second direction. The axes of the first feed roller and the second feed roller are both parallel to a third direction, which is perpendicular to both the first and second directions. The first feed roller is connected to a driving member, which drives the first feed roller to move closer to and / or away from the second feed roller. The second feed roller carries the material strip.

[0008] In some embodiments, the lifting component includes two lifting assemblies, with the second feed roller of one of the conveying assemblies located between the two lifting assemblies in the first direction, and the two lifting assemblies used to drive the material belt in the other conveying assembly to move in a direction opposite to the second direction.

[0009] In some embodiments, the lifting assembly includes a power component and a lifting roller, the lifting roller being rotatably connected to the power component, the power component driving the lifting roller to move in a direction parallel to the second direction, the axis of the lifting roller being parallel to the third direction, and the lifting roller supporting the material belt.

[0010] In some embodiments, the lifting assembly further includes a bracket connected to the power component and rotatably connected to the lifting roller.

[0011] In some embodiments, there are multiple lifting rollers, and the multiple lifting rollers are spaced apart along the first direction.

[0012] In some embodiments, there are two drive members, and the two drive members are located at opposite ends of the first feed roller.

[0013] In some embodiments, both the first feed roller and the second feed roller are configured as spindle shapes.

[0014] In some embodiments, the driving component is a cylinder with an air inlet, and the stamping feeding device further includes a pressure detection component for detecting the airflow pressure in the air inlet.

[0015] In some embodiments, the stamping feeding device further includes a non-contact measuring element, which is arranged sequentially with the conveying assembly along the first direction. The non-contact measuring element is used to detect the length of the material belt in the conveying assembly that moves along the first direction.

[0016] The stamping feeding device provided in this application has the following advantages: since it includes a lifting component and a plurality of conveying components arranged sequentially along a first direction; each conveying component is used to convey a strip of one material, and different conveying components are used to convey strips of different materials, when the stamping feeding device is used to convey the first strip, when the strip conveyed by any conveying component passes over another conveying component, the strip passing over the other conveying component can be driven to move in the opposite direction to the second direction, so as to avoid the strip conveyed by any conveying component from contacting the other conveying component and causing the strip to be scratched. Thus, the stamping feeding device can be used to convey the first strip and the second strip of different materials. Attached Figure Description

[0028] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0029] In the stamping production of vehicle parts, the stamping feeding device is a crucial link in ensuring stamping efficiency and product quality. As the core component of the stamping feeding device, the performance of the feed roller directly affects the feeding accuracy and stability. Traditional feed rollers often use high-strength materials, and the friction between them and the sheet metal is improved through optimized surface treatment processes.

[0030] With the increasing use of aluminum sheets and other components in body-in-white, stamping feeding devices need to transport strips of different materials. In order to avoid cross-contamination and damage to the strips, different feeding rollers are required for different strips. However, traditional stamping feeding devices only have one type of feeding roller, so they can only transport strips of a single material.

[0031] In view of this, this application provides a stamping feeding device, which includes a lifting component and a plurality of conveying components arranged sequentially along a first direction; each conveying component is used to convey a strip of one material, and different conveying components are used to convey strips of different materials. Therefore, when the stamping feeding device is used to convey the first strip, when the strip conveyed by any conveying component passes over another conveying component, the strip passing over the other conveying component can be driven to move in the opposite direction to the second direction, so as to avoid the strip conveyed by any conveying component from contacting the other conveying component and causing the strip to be scratched. Thus, the stamping feeding device can be used to convey the first strip and the second strip of different materials.

[0032] Please refer to Figure 1 and Figure 2 This application provides a stamping feeding device 100, including a lifting component and a plurality of conveying components arranged sequentially along a first direction, which may be the direction indicated by arrow K in the figure.

[0033] Any conveyor assembly is used to convey a strip of one material, while different conveyor assemblies are used to convey strips of different materials.

[0034] The lifting component is used to drive the conveyor belt that has passed over another conveyor component to move in a direction opposite to the second direction when the conveyor belt of any conveyor component passes over another conveyor component. The second direction is perpendicular to the first direction and can be the direction indicated by arrow L in the figure.

[0035] The lifting components may include cylinders, hydraulic cylinders or linear modules, and lifting rollers 141, etc.

[0036] For example, a plurality of conveying components include a first conveying component 101 and a second conveying component 102. The first conveying component 101 is used to convey a first material belt, and the second conveying component 102 is used to convey a second material belt. The material of the second material belt is different from that of the first material belt. For example, the first material belt is made of steel, and the second material belt is made of aluminum.

[0037] During use, the stamping feeding device 100 provided in the above embodiment: when the first conveying component 101 conveys the first material belt along the first direction, the lifting component drives the first material belt passing above the second conveying component 102 to move in the opposite direction to the second direction, so as to avoid the first material belt from contacting the second conveying component 102 and causing the first material belt to be scratched.

[0038] When the second conveying assembly 102 is used to convey the second material belt along the first direction, the lifting component is used to drive the second material belt above the first conveying assembly 101 to move in the opposite direction to the second direction, so as to avoid the second material belt from contacting the first conveying assembly 101 and causing the second material belt to be scratched.

[0039] As can be seen from the above, the stamping feeding device 100 provided in this application embodiment includes a lifting component and a plurality of conveying components arranged sequentially along the first direction; each conveying component is used to convey a strip of one material, and different conveying components are used to convey strips of different materials. Therefore, when using the stamping feeding device 100 to convey the first strip, when the strip conveyed by any conveying component passes over another conveying component, the strip passing over the other conveying component can be driven to move in the opposite direction to the second direction, so as to avoid the strip conveyed by any conveying component from contacting the other conveying component and causing the strip to be scratched. Thus, the stamping feeding device 100 can be used to convey the first strip and the second strip of different materials.

[0040] The conveying assembly includes a first feeding roller 11 and a second feeding roller 12. The first feeding roller 11 and the second feeding roller 12 are arranged sequentially along a second direction. The axis of the first feeding roller 11 and the axis of the second feeding roller 12 are both parallel to a third direction, which is perpendicular to both the first and second directions. The third direction can be the direction indicated by arrow M in the figure. The first feeding roller 11 is connected to a driving member 13, which is used to drive the first feeding roller 11 to move closer to and / or away from the second feeding roller 12. The second feeding roller 12 is used to carry the material belt.

[0041] By adopting the above scheme, the material belt can be conveyed by the cooperation of the first feeding roller 11 and the second feeding roller 12.

[0042] It is understood that the lifting component is used to drive the material belt passing over another conveyor component to move in the opposite direction to the second direction when the material belt conveyed by any conveyor component passes over another conveyor component, so as to avoid the material belt above the other conveyor component from contacting the second feed roller 12 of the other conveyor component.

[0043] For example, when the first feed roller 11 and the second feed roller 12 of the first conveying assembly 101 are used to convey the first material belt in the first direction, the lifting component is used to drive the first material belt above the second feed roller 12 of the second conveying assembly 102 to move in the opposite direction to the second direction, so as to avoid the first material belt from contacting the second feed roller 12 of the second conveying assembly 102 and causing the first material belt to be scratched.

[0044] When the first feed roller 11 and the second feed roller 12 of the second conveying assembly 102 convey the second material belt along the first direction, the lifting component is used to drive the second material belt above the second feed roller 12 of the first conveying assembly 101 to move in the opposite direction to the second direction, so as to avoid the second material belt from contacting the second feed roller 12 of the first conveying assembly 101 and causing the second material belt to be scratched.

[0045] It is also understandable that the surface materials of the first feed roller 11 and the second feed roller 12 of different conveying components are different. For example, when the first material strip is steel, the first feed roller 11 and the second feed roller 12 of the first conveying component 101 can be steel feed rollers. When the second material strip is aluminum, since aluminum has a low coefficient of friction and is prone to slipping, the first feed roller 11 and the second feed roller 12 of the second conveying component 102 can be rubber-coated feed rollers to increase the coefficient of friction.

[0046] In other embodiments, the first feed roller 11 and the second feed roller 12 of different conveying components can also be made of steel rollers, and the contact portions of them with the first and second material strips are roughened. The roughness of the roughening treatment is determined according to the properties of steel and aluminum to ensure the surface quality of the first and second material strips while improving the coefficient of friction. For example, the surface roughness of the first feed roller 11 and the second feed roller 12 of the first conveying component 101 in contact with the first material strip is controlled at 1.6±0.2, and the surface roughness of the first feed roller 11 and the second feed roller 12 of the second conveying component 102 in contact with the second material strip is controlled at 0.8±0.2.

[0047] Optionally, the first feeding roller 11 and the second feeding roller 12 are connected to the same servo motor 18. The servo motor 18 is used to drive the first feeding roller 11 and the second feeding roller 12 to rotate synchronously to ensure feeding accuracy. Guide rails are provided in the front-to-back and left-to-right directions of the first feeding roller 11. The first feeding roller 11 and the second feeding roller 12 are each equipped with two sets of support rollers to ensure force balance.

[0048] For example, the first feeding roller 11 is connected to the frame 16, and the frame 16 is provided with limit wheels 17 on both sides to ensure the stability of the first feeding roller 11 when it moves in a direction parallel to the second direction.

[0049] Please refer to Figure 1 and Figure 2 In some embodiments, the lifting component includes two lifting assemblies 14. In a first direction, a second feed roller 12 of a conveying assembly is located between the two lifting assemblies 14. The two lifting assemblies 14 are used to drive the material belt in the other conveying assembly to move in a direction opposite to the second direction.

[0050] By adopting the above scheme, two first lifting components 14 can be used to drive the material belt to move in the opposite direction to the second direction, so as to avoid the material belt from contacting the second feeding roller 12 of another conveying component.

[0051] It is understood that the lifting components can be set in two groups. The second feeding roller 12 of one conveying component is located between the two lifting components 14 in one group, and the second feeding roller 12 of the other conveying component is located between the two lifting components 14 in the other group.

[0052] Optionally, the lifting assembly 14 includes a power component 142 and a lifting roller 141. The lifting roller 141 is rotatably connected to the power component 142. The power component 142 is used to drive the lifting roller 141 to move in a direction parallel to the second direction. The axis of the lifting roller 141 is parallel to the third direction. The lifting roller 141 is used to support the material belt.

[0053] With this configuration, the lifting roller 141 can be driven by the power unit 142 to move in the opposite direction to the second direction to support the material belt and prevent the material belt from contacting the second feed roller 12 of the other conveying component.

[0054] For example, the power component 142 may be a cylinder, a hydraulic cylinder, or a linear module, etc.

[0055] The lifting assembly 14 also includes a bracket 143, which is connected to the power component 142 and is rotatably connected to the lifting roller 141.

[0056] This configuration facilitates the rotatable connection between the lifting roller 141 and the power component 142.

[0057] Optionally, there may be multiple lifting rollers 141, and the multiple lifting rollers 141 are spaced apart along the first direction.

[0058] This configuration allows the material belt to be supported simultaneously by multiple lifting rollers 141, thus improving its stability.

[0059] Understandably, when conveying the belt along the first direction, the belt may roll on the lifting roller 141.

[0060] Please refer to Figure 1 and Figure 2 In some embodiments, there are two drive members 13, and the two drive members 13 are located at the two ends of the first feed roller 11, respectively.

[0061] By adopting the above scheme, when the driving component 13 drives the first feeding roller 11 to approach and move away from the second feeding roller 12, it can ensure that the movement of the first feeding roller 11 is relatively stable and that the gap between the two ends of the first feeding roller 11 and the two ends of the second feeding roller 12 is consistent.

[0062] Optionally, both the first feed roller 11 and the second feed roller 12 are configured as spindle shapes.

[0063] This configuration can prevent the first feeding roller 11 and the second feeding roller 12 from deviating during feeding.

[0064] Please refer to Figure 1 and Figure 2 In some embodiments, the drive element 13 is a cylinder with an air inlet, and the stamping feeding device 100 also includes a pressure detection element for detecting the airflow pressure in the air inlet.

[0065] By adopting the above solution, it is possible to avoid the airflow pressure in the first air inlet from fluctuating, causing pressure fluctuations that lead to inconsistent gaps between the first feeding roller 11 and the second feeding roller 12, which in turn causes feeding deviation or slippage.

[0066] It should be noted that the first pressure detection element can be a pressure sensor. When there are two first driving elements 13, and the two first driving elements 13 are located at both ends of the first feeding roller 11, the first air inlet of both first driving elements 13 is connected to the first pressure detection element to ensure that the gap between the two ends of the first feeding roller 11 and the two ends of the second feeding roller 12 is consistent.

[0067] Please refer to Figure 1 and Figure 2 In some embodiments, the stamping feeding device 100 further includes a non-contact measuring element 15, which is arranged sequentially with the conveying assembly along a first direction. The non-contact measuring element 15 is used to detect the length of the material belt in the conveying assembly that moves along the first direction.

[0068] By adopting the above solution, the feeding length of the material strip can be fed back in real time, thus avoiding dimensional deviations.

[0069] For example, the non-contact measuring element 15 can be a Doppler velocimeter. The Doppler velocimeter emits ultrasonic waves of a certain frequency. When the conveyor belt moves, the frequency of the reflected waves changes, thereby allowing the conveyor belt's speed to be calculated and converted into its length.

[0070] The stamping feeding device 100 provided in this application embodiment solves the problems of feeding deviation, slippage, and unstable feeding step length in the stamping feeding device 100, eliminates batch scrapping of material strips, realizes steel-aluminum mixed production line, achieves servo feeding of steel-aluminum uncoiling line at a lower cost, operates stably, meets the production needs of steel-aluminum uncoiling line, improves uncoiling line output, and greatly reduces costs.

[0071] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
