Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, and in particular to a sheet bending device. Background Technology

[0002] After hot pressing, the sheet material is formed into a bull's horn shape on both sides. The notch at the bull's horn is located at the edge of the product body. During the bending process, the sheet material is easily pulled out at the notch due to the uneven bending and pulling force on both sides, which can easily cause the sheet material to break and result in defective sheet material. Based on this, a sheet bending device that can solve the above problems is proposed. Utility Model Content

[0007] As a further improvement to the above solution, the pressure block driving mechanism includes wedge-shaped grooves respectively opened on the two pressure blocks. The wedge-shaped grooves are located above the dovetail slide. A push plate is provided on the inner side of each wedge-shaped groove. A crossbeam is fixedly connected to one side of the two push plates. A top block is fixedly connected to the side of the crossbeam near the pressure block. A crossbeam pushing mechanism is provided on the side of the crossbeam away from the pressure block. Limiting balance mechanisms are provided on both sides of the crossbeam.

[0008] As a further improvement to the above solution, the beam pushing mechanism includes a hydraulic cylinder fixedly connected to the inside of the housing, and the output end of the hydraulic cylinder is connected to one side of the beam.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0014] Example: Please combine Figure 1 - Figure 5This embodiment of a sheet bending device includes a housing 4. Limiting blocks 9 are fixedly connected to both sides of the bottom of the housing 4. Two limiting holes are opened on the limiting blocks 9. Dovetail grooves 16 are opened on the lower side of the two limiting blocks 9. Dovetail slides 14 are slidably connected to the inner side of the two dovetail slides 16. A pressure block 6 is fixedly connected to one end of the two dovetail slides 14. A limiting slide rod mechanism is provided on the side of the pressure block 6 near the limiting blocks 9. A pressure block driving mechanism that brings the two pressure blocks 6 closer to each other is provided on the other side of the pressure block 6. A loading platform 1 is fixedly connected to the side of the housing 4 near the pressure block 6. An installation groove 2 is opened on the upper side of the loading platform 1.

[0015] By simultaneously driving the two pressure blocks 6 to move closer to each other, the special structure of the bullhorn-shaped material sheet is bent at equal distances and with equal thrust, thereby ensuring the product qualification rate.

[0016] In this embodiment, the limiting slide bar mechanism includes two slide bars 8 that are fixedly connected to the side of the pressure block 6 near the limiting block 9. The slide bars 8 have a limiting function and are slidably connected to the inner side of the limiting block 9. An elastic reset mechanism is provided on the outer side of each slide bar 8.

[0017] Please combine Figure 2 As shown, the elastic reset mechanism includes a spring 7 sleeved on the outside of each slide bar 8. When the push plate 5 is pulled out, the pressure block 6 can be automatically reset. One end of each spring 7 is fixedly connected to one side of the limit block 9, and the other end of each spring 7 is fixedly connected to one side of the pressure block 6.

[0018] Please combine Figure 5 As shown, the pressure block driving mechanism includes wedge-shaped grooves 13 respectively opened on two pressure blocks 6. The wedge-shaped grooves 13 are located above the dovetail slide table 14. A push plate 5 is provided on the inner side of each wedge-shaped groove 13. The mutual cooperation between the wedge-shaped groove 13 and the push plate 5 is as follows: Figure 4 As shown, the push plate 5 has a triangular wedge structure. When the push plate 5 is inserted forward into the wedge groove 13, the wedge groove 13 is squeezed and indirectly pushes the pressure block 6 to move to one side. A crossbeam 10 is fixedly connected to one side of both push plates 5. A top block 3 is fixedly connected to the side of the crossbeam 10 near the pressure block 6. A crossbeam pushing mechanism is provided on the side of the crossbeam 10 away from the pressure block 6. Limit balance mechanisms are provided on both sides of the crossbeam 10.

[0019] Please combine Figure 2 As shown, the beam pushing mechanism includes a hydraulic cylinder 12 fixedly connected to the inside of the housing 4, and the output end of the hydraulic cylinder 12 is connected to one side of the beam 10.

[0020] Please combine Figure 3As shown, the limiting and balancing mechanism includes slots 15 on both sides of the crossbeam 10. The inner sides of the two slots 15 are slidably connected to the plates 11. Each plate 11 is fixedly connected to the inner side of the housing 4. The plates 11 on both sides provide support for the balance of the crossbeam 10.

[0021] The implementation principle of the sheet bending device in this application embodiment is as follows: First, one end of the horn-shaped sheet to be bent is placed inside the mounting groove 2. Then, the hydraulic cylinder 12 is activated to push the crossbeam 10 to move along the direction of the clamping plate 11, so that the two push plates 5 are accurately inserted into the wedge groove 13 respectively. Due to the squeezing of one side of the push plate 5, the pressure block 6 on both sides slides along the direction of the slide rod 8. The slide rod 8 slides inside the limiting block 9, and the spring 7 is deformed and stretched. At the same time, the dovetail slide table 14 slides inside the dovetail slide groove 16. The two branches of the horn sheet are bent and move closer to each other. When the two branches are bent to be parallel, their first section is squeezed by the top block 3, thus completing the bending process.

[0022] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
