Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically a high-precision hydraulic sheet metal bending machine. Background Technology

[0002] A high-precision hydraulic sheet metal bending machine is a piece of equipment used for processing sheet metal. Powered by a hydraulic system, it precisely bends the sheet metal to a preset angle and shape. This equipment is widely used in industries such as metal processing, machinery manufacturing, automotive manufacturing, and aerospace to produce various complex metal parts.

[0003] However, existing high-precision hydraulic sheet metal bending machines have the following drawbacks: (1) Existing high-precision hydraulic plate bending machines have weak functions in improving the flexibility and convenience of operation. Because traditional bending machines require a certain amount of time and effort to disassemble and assemble the bending head, they increase the manual working time and reduce the efficiency of bending head disassembly and assembly. (2) Existing high-precision hydraulic sheet metal bending machines have weak functions in improving bending accuracy and product quality. Due to the extrusion of the sheet metal during the bending process, the position will shift, resulting in a decrease in bending accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision hydraulic sheet metal bending machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision hydraulic sheet metal bending machine, comprising: a machine body, a replacement component, and a positioning component. A hydraulic cylinder is provided on one side of the machine body. A connecting block is fixedly connected to the bottom of the hydraulic cylinder. A telescopic rod is fixedly connected to the inner top wall of the connecting block. A spring is sleeved on the outer surface of the telescopic rod. A mounting block is fixedly connected to the bottom of the telescopic rod. A limit slider is provided on the outer surface of the mounting block. A bending plate is fixedly connected to the bottom of the limit slider. A bending die is fixedly connected to the inner side wall of the machine body. A fixing plate is fixedly connected to the top of the bending die. An adjusting screw is threaded inside the fixing plate. A positioning plate is rotatably connected to the end of the adjusting screw near the bending die. An adjusting slider is fixedly connected to the bottom of the positioning plate. A measuring ruler is fixedly connected to one end of the bending die.

[0006] Optionally, a limiting groove is provided at the bottom of the connecting block, and the outer surface of the limiting slider is slidably connected to the inner wall of the limiting groove. When the limiting slider slides inside the limiting groove, the limiting groove limits the limiting slider to prevent the limiting slider from shifting its position.

[0007] Optionally, the top of the spring is fixedly connected to the inner top wall of the connecting block, and the bottom of the spring is fixedly connected to the top of the mounting block. Through the connection between the spring, the connecting block, and the mounting block, the connecting block supports and fixes one end of the spring. When the spring extends or retracts, it will cause the mounting block to move accordingly.

[0008] Optionally, the top of the bending die is provided with an adjusting groove, and the outer surface of the adjusting slider is slidably connected to the inner wall of the adjusting groove. When the adjusting slider is inside the adjusting groove, the adjusting groove limits the adjusting slider to prevent the adjusting slider from shifting position.

[0009] Optionally, a storage frame is fixedly connected to one bottom side of the machine body. A partition is provided on the inner side wall of the storage frame. A rectangular slider is fixedly connected to one side of the partition. The storage frame allows the sheet material to be bent to be placed in a concentrated manner. When the partition is moved, the rectangular slider limits the position of the partition. The partition can adjust the internal space of the storage frame.

[0010] Optionally, the inner wall of the storage frame is provided with a rectangular groove, and the outer surface of the rectangular slider is slidably connected to the inner wall of the rectangular groove. When the rectangular slider slides inside the rectangular groove, the rectangular groove limits the rectangular slider to prevent the rectangular slider from shifting position.

[0011] Optionally, the top of the limiting slider is provided with a mounting slot, and the outer surface of the mounting block is engaged with the inside of the mounting slot. When the mounting block is engaged with the inside of the mounting slot, the mounting slot limits the mounting block and stabilizes the position of the mounting block.

[0012] Optionally, the number of positioning plates is two, and the number of adjusting sliders is two. The two positioning plates and the adjusting sliders can be used to position both sides of the sheet material.

[0013] Optionally, the bottom four corners of the machine body are fixedly connected to the legs, and the bottom of the legs is fixedly connected to the anti-slip pads. The legs support and fix the machine body. The anti-slip pads are made of rubber and can improve the stability of the machine body by connecting with the legs.

[0014] Optionally, the top of the bending die is provided with a bending groove, and the bending plate is aligned vertically with the bending groove. Because the bending plate and the bending groove are aligned vertically, the sheet material can be bent stably.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This high-precision hydraulic sheet metal bending machine, through component replacement settings, allows for operation by sliding the limit slider into the connecting block, simultaneously causing the spring and telescopic rod to retract. After the limit slider and connecting block are in contact, the spring rebounds, causing the mounting block to engage in the slot at the top of the limit slider, ensuring a stable connection between the limit slider and the connecting block, thus completing the installation of the bent sheet. Reverse sliding of the limit slider allows for disassembly of the bent sheet, achieving improved operational flexibility and convenience. This avoids the time and effort required for disassembling and assembling the bending head in traditional bending machines, which increases manual labor time and reduces bending head assembly and disassembly efficiency.

[0016] This high-precision hydraulic sheet metal bending machine, through the setting of the positioning component, allows the operator to rotate the adjusting screw while the fixed plate limits the adjusting screw. The rotation of the adjusting screw drives the positioning plate to position the sheet metal. At this time, the adjusting slider limits the movement of the positioning plate. The measuring ruler allows the operator to easily observe the positioning distance, thereby improving the bending accuracy and product quality. It also prevents the sheet metal from shifting due to compression during the bending process, which would otherwise reduce the bending accuracy. Attached Figure Description

[0020] Please see Figures 1-4 As shown, this utility model provides a technical solution: a high-precision hydraulic sheet metal bending machine, comprising: a machine body 1, a replacement assembly 2, and a positioning assembly 3. A hydraulic cylinder 201 is provided on one side of the machine body 1. A connecting block 202 is fixedly connected to the bottom of the hydraulic cylinder 201.

The bottom of the limiting slider 206 is fixedly connected to the bending plate 207. When the limiting slider 206 is slid into the connecting block 202, the spring 204 and the telescopic rod 203 are simultaneously retracted. After the limiting slider 206 is in contact with the connecting block 202, the spring 204 rebounds and drives the mounting block 205 to be inserted into the slot at the top of the limiting slider 206, so that the limiting slider 206 and the connecting block 202 are stably connected, thereby completing the installation of the bending plate 207. The bending plate 207 can be disassembled by sliding the limiting slider 206 in the opposite direction. A bending die 301 is fixedly connected to the inner wall of the machine body 1. A fixed plate 302 is fixedly connected to the top of the bending die 301. An adjusting screw 303 is threadedly connected to the inside of the fixed plate 302. A positioning plate 304 is rotatably connected to one end of the adjusting screw 303 near the bending die 301. An adjusting slider 305 is fixedly connected to the bottom of the positioning plate 304. A measuring ruler 306 is fixedly connected to one end of the bending die 301. When the adjusting screw 303 is rotated, the fixed plate 302 limits the adjustment screw 303. The rotation of the adjusting screw 303 drives the positioning plate 304 to position the sheet metal. At this time, the adjusting slider 305 limits the movement of the positioning plate 304. The measuring ruler 306 allows the operator to easily observe the positioning distance. The bottom of the connecting block 202 is provided with a limiting groove 4. The outer surface of the limiting slider 206 is slidably connected to the inner wall of the limiting groove 4. When the limiting slider 206 slides inside the limiting groove 4, the limiting groove 4 limits the limiting slider 206 to prevent the limiting slider 206 from shifting its position. The top of the spring 204 is fixedly connected to the inner top wall of the connecting block 202, and the bottom of the spring 204 is fixedly connected to the top of the mounting block 205. Through the connection between the spring 204, the connecting block 202, and the mounting block 205, the connecting block 202 supports and fixes one end of the spring 204. When the spring 204 extends or retracts, it will drive the mounting block 205 to move accordingly. The top of the bending die 301 is provided with an adjustment groove 5. The outer surface of the adjustment slider 305 is slidably connected to the inner wall of the adjustment groove 5. When the adjustment slider 305 is inside the adjustment groove 5, the adjustment groove 5 limits the adjustment slider 305 to prevent the adjustment slider 305 from shifting position. A storage frame 6 is fixedly connected to the bottom side of the machine body 1. A partition 7 is provided on the inner side wall of the storage frame 6. A rectangular slider 8 is fixedly connected to one side of the partition 7. The storage frame 6 can be used to place the material to be bent 207 in a concentrated manner. When the partition 7 is moved, the rectangular slider 8 limits the position of the partition 7. The partition 7 can adjust the internal space of the storage frame 6. The inner wall of the storage box 6 is provided with a rectangular groove 9. The outer surface of the rectangular slider 8 is slidably connected to the inner wall of the rectangular groove 9. When the rectangular slider 8 slides inside the rectangular groove 9, the rectangular groove 9 limits the rectangular slider 8 to prevent the rectangular slider 8 from shifting position. The top of the limiting slider 206 is provided with a mounting slot 10. The outer surface of the mounting block 205 is engaged with the inside of the mounting slot 10. When the mounting block 205 is engaged into the inside of the mounting slot 10, the mounting slot 10 limits the mounting block 205, so that the position of the mounting block 205 is stabilized. There are two positioning plates 304 and two adjusting sliders 305. By setting up two positioning plates 304 and adjusting sliders 305, both sides of the sheet can be positioned. The four corners of the bottom of the body 1 are fixedly connected to the feet 11, and the bottom of the feet 11 is fixedly connected to the anti-slip pads 12. The feet 11 support and fix the body 1. The anti-slip pads 12 are made of rubber and can improve the stability of the body 1 by connecting with the feet 11. The top of the bending die 301 is provided with a bending groove, and the bending plate 207 is aligned vertically with the bending groove. Because the bending plate 207 is aligned vertically with the bending groove, the sheet material can be bent stably.

[0021] In this invention, the working steps of the device are as follows: First step: Slide the limiting slider 206 into the connecting block 202, simultaneously causing the spring 204 and telescopic rod 203 to retract. After the limiting slider 206 and the connecting block 202 are in contact, the spring 204 rebounds and causes the mounting block 205 to engage in the slot at the top of the limiting slider 206, thus ensuring a stable connection between the limiting slider 206 and the connecting block 202, thereby completing the installation of the bent plate 207. Sliding the limiting slider 206 in the opposite direction can disassemble the bent plate 207. Rotating the adjusting screw 303 simultaneously limits the adjusting screw 303 to a fixed position. The rotation of the adjusting screw 303 drives the positioning plate 304 to position the plate. At this time, the adjusting slider 305 limits the movement of the positioning plate 304. The measuring ruler 306 allows the operator to easily observe the positioning distance.

[0022] The second step: When the limiting slider 206 slides inside the limiting groove 4, the limiting groove 4 limits the limiting slider 206 to prevent the limiting slider 206 from shifting its position. Through the connection of the spring 204 with the connecting block 202 and the mounting block 205, the connecting block 202 supports and fixes one end of the spring 204. When the spring 204 extends or retracts, it will drive the mounting block 205 to move accordingly. When the adjusting slider 305 is inside the adjusting groove 5, the adjusting groove 5 limits the adjusting slider 305 to prevent the adjusting slider 305 from shifting its position.

[0023] The third step: The storage frame 6 allows for the centralized placement of the sheet metal 207 to be bent. When the partition 7 is moved, the rectangular slider 8 limits the position of the partition 7. The partition 7 can adjust the internal space of the storage frame 6. When the rectangular slider 8 slides inside the rectangular groove 9, the rectangular groove 9 limits the rectangular slider 8 to prevent the rectangular slider 8 from shifting position. When the mounting block 205 is inserted into the mounting slot 10, the mounting slot 10 limits the mounting block 205 to stabilize its position. The two positioning plates 304 and the adjusting slider 305 can position both sides of the sheet metal. The bracket 11 supports and fixes the machine body 1. The anti-slip pad 12 is made of rubber and its connection with the bracket 11 can improve the stability of the machine body 1. Because the bending plate 207 is aligned vertically with the bending groove, the sheet metal can be bent stably.
