Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and more specifically, to a sheet metal bending and forming device. Background Technology

[0002] Sheet metal work is a comprehensive cold processing technology for thin metal sheets (usually less than 6mm). It includes shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its most significant characteristic is that the thickness of the same part is consistent. Products processed through sheet metal work are called sheet metal parts. The term "sheet metal part" generally varies across different industries, but it is often used in assembly contexts. Sheet metal parts require bending processing during production.

[0003] Existing processing and bending devices mostly involve directly fixing the processing block to the worktable during use. After prolonged use, the bending groove is prone to damage, making it difficult to disassemble and replace the processing block in real time. Instead, the entire device needs to be disassembled and replaced, which causes great inconvenience.

[0004] A search revealed a Chinese patent with publication number CN216226280U that discloses a sheet metal bending and forming device. This utility model solves the problem that most existing bending devices directly fix the processing block to the worktable during use, and the bending groove is prone to damage after long-term use, making it difficult to disassemble and replace the processing block in real time.

[0005] However, in actual use, the forming device cannot guarantee the uniformity of bending force between the upper and lower dies on the long sheet metal material during the bending process, which will cause wrinkles on the surface of the long sheet metal material and affect the bending accuracy of the long sheet metal material. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sheet metal processing bending and forming device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sheet metal bending and forming device includes a base frame, a support fixedly connected to the top of the base frame, a storage rack fixedly connected to one side of the base frame, a cylinder fixedly connected to the top of the support, a connecting frame fixedly connected to the bottom of the cylinder, an upper template fixedly connected to the bottom of the connecting frame, two guide rods fixedly connected to the upper surface of the upper template, the outer sides of the guide rods being slidably connected to the inner side of the support, an adjustable bending mechanism being provided on the base frame and the inner side of the support, and a material storage mechanism being provided on one side of the storage rack.

[0009] By adopting the above technical solution: using a cylinder to push the upper template and combining two guide rods to slide the bracket, the upper template is pressed down.

[0010] As a further description of the above technical solution: the adjustable bending mechanism includes multiple cylinders II, the outer side of each cylinder II is fixedly connected to the inner side of the upper template, a pressure rod is hinged to the bottom end of each cylinder II, and a sliding groove is opened at both ends of the pressure rod. A connecting frame I is snapped into the inner side of the sliding groove. Multiple cylinders III are fixedly connected to the inner side of the base frame, a fixing frame is fixedly connected to the top of each cylinder III, a connecting frame II is fixedly connected to the top of the fixing frame, a lower mold base is slidably connected to the outer side of the connecting frame II, and two positioning plates are fixedly connected to the top of the lower mold base. The positioning plates are symmetrically arranged on both sides of the connecting frame II, and the multiple cylinders III are evenly distributed on the inner side of the base frame.

[0011] By adopting the above technical solution: using multiple cylinders to push the pressure rod and connecting frame 1, the connecting frame 1 can be adjusted to bend in an arc. Using multiple cylinders to push the fixing frame and connecting frame 2, the multiple lower mold bases can be adjusted to bend in an arc. This allows the multiple pressure rods and connecting frame 1 to form a relatively close bending angle with the lower mold base and positioning plate, thereby improving the bending accuracy of long sheet metal materials.

[0012] As a further description of the above technical solution: the storage mechanism includes multiple support rods, the outer side of the support rods is slidably connected to the inner side of the storage rack, multiple base plates are fixedly connected to the inner side of the storage rack, the inner side of the base plates is slidably connected to the inner side of the support rods, a top plate is fixedly connected to the top of the support rods, a spring is sleeved on the outer side of the support rods, a storage box is provided on the top of the top plate, the outer side of the storage box is slidably connected to the inner side of the storage rack, and a handle is fixedly connected to one side of the storage box.

[0013] By adopting the above technical solution: using a storage box to place long sheet metal materials, and using multiple springs to provide elastic support for the top plate, the impact between the storage box and the long sheet metal materials is reduced when multiple long sheet metal materials are placed inside the storage box.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting an adjustable bending mechanism, compared with the existing technology, multiple lower die bases, positioning plates, pressure rods and connecting frames are used to bend and deflect the lower die and the upper die, so that the long sheet metal material is dynamically provided with local support during the forming process, preventing the long sheet metal material from wrinkling or collapsing during the bending process, and improving the consistency and accuracy of the bending angle of the long sheet metal material.

[0016] 2. By setting up a material storage mechanism, compared with the existing technology, multiple springs are used to provide elastic support for the top plate and the storage box, so that the storage box can store multiple long sheet metal materials after bending and forming, which facilitates the continuity of bending of long sheet metal materials by workers.

[0026] Reference Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the adjustable bending mechanism includes multiple cylinders 2 8. The outer side of cylinder 2 8 is fixedly connected to the inner side of the upper template 6. A pressure rod 9 is hinged to the bottom end of cylinder 2 8. Both ends of the pressure rod 9 are provided with sliding grooves 10. A connecting frame 1 11 is engaged inside the sliding grooves 10. Multiple cylinders 3 12 are fixedly connected to the inner side of the base frame 1. A fixing frame 13 is fixedly connected to the top of cylinder 3 12. A connecting frame 2 14 is fixedly connected to the top of the fixing frame 13. A lower mold base 15 is slidably connected to the outer side of the connecting frame 2 14. The top of the lower mold base 15 is fixedly connected to the lower mold base 15. The fixed connection has two positioning plates 16, which are symmetrically arranged on both sides of the connecting frame 14. Multiple cylinders 12 are evenly distributed inside the base frame 1. Multiple cylinders 8 push the pressure rod 9, the slide groove 10 and the connecting frame 11 to bend in an arc shape. Multiple cylinders 12 push the fixed frame 13 and the connecting frame 14 to fit the multiple lower mold bases 15 and the positioning plates 16 with the bottom sides of the pressure rod 9, the slide groove 10 and the connecting frame 11, so that the long sheet metal material maintains accuracy during the bending process.

[0027] Reference Figure 2 and Figure 5 As shown, the storage mechanism includes multiple support rods 17. The outer side of the support rods 17 is slidably connected to the inner side of the storage rack 3. Multiple base plates 18 are fixedly connected to the inner side of the storage rack 3. The inner side of the base plates 18 is slidably connected to the inner side of the support rods 17. A top plate 19 is fixedly connected to the top of the support rods 17. A spring 20 is sleeved on the outer side of the support rods 17. A storage box 21 is provided on the top of the top plate 19. The outer side of the storage box 21 is slidably connected to the inner side of the storage rack 3. A handle 22 is fixedly connected to one side of the storage box 21. The multiple springs 20 push the top plate 19 and the support rods 17 to slide inside the storage rack 3, so that the storage box 21 can buffer the impact force of placing long sheet metal materials, so that multiple long sheet metal materials can be quickly placed into the storage box 21, reducing the impact force between the long sheet metal materials and the storage box 21.

[0028] The working principle of this utility model is as follows: When processing and bending long sheet metal materials, firstly, according to the required bending range of the long sheet metal materials, multiple cylinders 12 are activated to raise and lower, causing the fixed frame 13 and connecting frame 14 to rise and fall. This allows the connecting frame 14 to raise and lower the outer lower mold base 15. Under the push of the multiple cylinders 12, the multiple lower mold bases 15 can be bent into an arc shape. Then, the long sheet metal materials are placed inside the multiple lower mold bases 15 and the positioning plate 16. After the long sheet metal materials are placed stably, cylinder 4 is activated to raise and lower the connecting frame 5 and the upper template 6. Combined with the two guide rods 7, the materials are guided and raised and lowered inside the bracket 2. This causes the multiple pressure rods 9 at the bottom of the upper template 6 and the connecting frame 11 to press down on the long sheet metal materials placed inside the lower mold bases 15 and the positioning plate 16. Multiple cylinders 8 are used to raise and lower the corresponding pressure rods 9. The connecting frame 11 is pushed so that it can slide in the groove 10 inside the corresponding pressure rod 9, so that the multiple pressure rods 9 and the connecting frame 11 form a bent downward pressing surface. This allows the multiple pressure rods 9 and the connecting frame 11 to press down and bend the long sheet metal materials inside the multiple lower mold bases 15 and positioning plates 16, while maintaining the precision of the bending of the long sheet metal materials. After the long sheet metal materials are bent and formed, they are taken out and placed inside the storage box 21. After the multiple long sheet metal materials are continuously bent and formed, they are placed, and multiple springs 20 are used to push the top plate 19 and the storage box 21, so that the storage box 21 can be elastically supported inside the storage rack 3, avoiding strong impact on the whole during the placement of the long sheet metal materials. Finally, the storage box 21 can be pulled out from one side of the storage rack 3, and the multiple long sheet metal materials can be transferred.
