Description

Technical Field

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

[0002] A bending machine is a processing device used to bend sheet metal into a desired shape. This type of machine is very common in the metal processing field, especially in the manufacturing industry. It can perform precise bending operations on sheet metal. The sheet metal to be bent is placed on a worktable, and the bending cutter moves downwards, working together with the bending die to bend the sheet metal to meet different design and functional requirements.

[0003] Most existing metal sheet bending equipment uses bolts and nuts to fix the bending dies, which cannot quickly switch the corresponding dies according to the processing requirements of different bending angles. This increases the downtime of the equipment and cannot eliminate the impact and vibration generated when the bending cutter falls. The metal sheet is prone to displacement or springback deviation due to vibration, and the angle and size of each bend cannot be guaranteed to be consistent.

[0004] Therefore, those skilled in the art have provided a metal sheet bending device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a metal sheet bending equipment. This equipment can quickly switch the corresponding mold according to the processing requirements of different bending angles, thereby shortening the mold change time, reducing equipment downtime, directly improving the overall efficiency of the equipment, and eliminating the impact and vibration generated when the bending cutter falls, thus avoiding displacement or springback deviation of the sheet metal due to vibration.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A metal sheet bending device includes a base, a support fixedly mounted at the rear end of the base, sliding grooves on both sides of the support, guide rods fixedly mounted inside the two sliding grooves, sliding sleeves slidably mounted on the outer walls of the two guide rods, and shock-absorbing springs sleeved on the outer walls of the two guide rods and located between the sliding grooves and the sliding sleeves. T-shaped slide rails are fixedly mounted on both sides of the upper end of the base and located below the support. T-shaped slide bars are slidably mounted inside the two T-shaped slide rails. An installation groove is opened on one side of the two T-shaped slide rails, and a locking groove is opened on one side of the two T-shaped slide bars and corresponds to the installation groove. A pressure plate is slidably mounted inside the two installation grooves. Two return springs are fixedly mounted inside the two installation grooves and located between the pressure plate and the installation groove. A chamfered locking block is fixedly mounted on one end of the two pressure plates and engages with the locking groove.

[0007] Furthermore, a mounting plate is fixedly connected between the two sliding sleeves, and a bending cutter is detachably provided at the lower end of the mounting plate. A hydraulic push rod is fixedly provided in the middle of the bracket, and the output end of the hydraulic push rod is fixedly connected to the upper end of the mounting plate. The above technical solution uses a hydraulic push rod to move the mounting plate, which in turn moves the bending cutter downwards, thereby bending the metal sheet.

[0008] Furthermore, the ends of the two pressure plates away from the chamfered block are fixedly connected to pull rods and slidably disposed inside the T-shaped slide rail. The ends of the two pull rods away from the pressure plates extend out of the T-shaped slide rail, and the ends of the two pull rods extending out of the T-shaped slide rail are fixedly connected to pull rings. By using the above technical solution, pulling the pull ring on one side of the T-shaped slide rail drives the pull rod to move, causing the pressure plate to move and causing the chamfered block to disengage from the slot. This allows the equipment to quickly switch to the corresponding mold according to the processing requirements of different bending angles, thereby shortening the mold change time.

[0009] Furthermore, a bending die is fixedly connected between the two T-shaped sliders and located at their upper ends; The above technical solution facilitates the bending of sheet metal by setting up a bending mold.

[0010] Furthermore, the base has first sliding grooves on both sides of its upper end, sliding rods are slidably arranged inside the two first sliding grooves, sliders are slidably arranged on the outer walls of the two sliding rods, and a sliding plate is fixedly connected between the two sliders and located at its upper end; The above technical solution allows the metal sheet to be brought close to the bending die by pushing the sliding plate, and then the metal sheet is pushed onto the bending die, which facilitates the bending of the metal sheet and brings convenience to the workers.

[0011] Furthermore, the upper sides of the sliding plate are provided with second sliding grooves, and sliding rods are slidably arranged inside the two second sliding grooves. Limiting plates are fixedly connected to the upper ends of the two sliders. Springs are sleeved on the outer walls of the two sliding rods and located between the second sliding grooves and the sliders. A pull handle is fixedly connected to the middle of the front end of the sliding plate. The above technical solution uses limiting plates on both sides of the sliding plate to correct and limit the metal sheet, ensuring that the metal sheet will not deviate when bending.

[0012] Furthermore, a control panel is fixedly installed on one side of the front end of the base; The above technical solution allows for the setup of a control panel to facilitate the control of the device's operation.

[0013] This utility model has the following beneficial effects: 1. The metal sheet bending equipment proposed in this utility model, by setting up a T-shaped slide bar, a slot, a pressure plate, a return spring, a chamfering block, and a pull rod, allows the equipment to quickly switch the corresponding mold according to the processing requirements of different bending angles. This shortens the mold change time, reduces equipment downtime, and directly improves the overall efficiency of the equipment. With the cooperation of the shock-absorbing spring, it can eliminate the impact and vibration generated when the bending cutter falls, avoid the sheet metal from displacement or springback deviation due to vibration, ensure that the angle and size of each bend are consistent, and thus improve the bending effect and ensure the stability of bending accuracy.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Reference Figure 1-5 This utility model provides a specific embodiment: a metal sheet bending device, including a base 1, a support 2 fixedly mounted at the rear end of the base 1, sliding grooves 3 formed on both sides inside the support 2, guide rods 4 fixedly mounted inside the two sliding grooves 3, sliding sleeves 5 slidably mounted on the outer walls of the two guide rods 4, and shock-absorbing springs 6 sleeved on the outer walls of the two guide rods 4 and located between the sliding grooves 3 and the sliding sleeves 5, and T-shaped slide rails 10 fixedly mounted on both sides of the upper end of the base 1 and located below the support 2, the two T-shaped slide rails 10 sliding inside the base 1... The device is equipped with T-shaped slide bars 11. Two T-shaped slide rails 10 have mounting grooves 12 on one side inside. Two T-shaped slide bars 11 have slots 13 on one side corresponding to the mounting grooves 12. Pressure plates 14 are slidably mounted inside the two mounting grooves 12. Two return springs 15 are fixedly mounted inside the two mounting grooves 12 and located between the pressure plates 14 and the mounting grooves 12. Chamfered locking blocks 16 are fixedly mounted at one end of each pressure plate 14 and engage with the slots 13. A mounting plate 7 is fixedly connected between the two sliding sleeves 5. A bending cutter 8 is detachably mounted on the lower end of plate 7. A hydraulic push rod 9 is fixedly mounted in the middle of bracket 2. The output end of the hydraulic push rod 9 is fixedly connected to the upper end of mounting plate 7. The hydraulic push rod 9 pushes the mounting plate 7 to move, thereby driving the bending cutter 8 to move downward, thus performing bending work on the metal sheet. The ends of the two pressure plates 14 away from the chamfering block 16 are fixedly connected to pull rods 17 and slidably mounted inside the T-shaped slide rail 10. The ends of the two pull rods 17 away from the pressure plates 14 extend out of the T-shaped slide rail 10. A pull ring 18 is fixedly connected to one end of the T-shaped slide rail 10. By pulling the pull ring 18 on one side of the T-shaped slide rail 10, the pull rod 17 is moved, causing the pressure plate 14 to move and causing the chamfering block 16 to disengage from the slot 13. This allows the equipment to quickly switch the corresponding mold according to the processing requirements of different bending angles, thereby shortening the mold changing time. A bending mold 19 is fixedly connected between the two T-shaped slide bars 11 and located at its upper end. The bending mold 19 is set to facilitate the bending of the sheet metal to be bent. Reference Figure 1 , 67. The base 1 has two first sliding grooves 20 on its upper sides. Sliding rods 21 are slidably mounted inside the two first sliding grooves 20. Sliding blocks 22 are slidably mounted on the outer walls of the two sliding rods 21. A sliding plate 23 is fixedly connected between the two sliding blocks 22 and located at its upper end. By pushing the sliding plate 23, the metal sheet is brought close to the bending die 19, and then pushed onto the bending die 19, thus facilitating the bending of the metal sheet and providing convenience for the workers. Second sliding grooves 28 are formed on both sides of the upper end of the sliding plate 23. Sliding rods 21 are slidably installed inside the two second slide grooves 28. Limiting plates 24 are fixedly connected to the upper ends of the two sliders 22. Springs 25 are sleeved on the outer walls of the two sliding rods 21 and are located between the second slide grooves 28 and the sliders 22. A handle 26 is fixedly connected to the middle of the front end of the sliding plate 23. The limiting plates 24 on both sides of the sliding plate 23 are used to correct and limit the metal plate, ensuring that the metal plate will not deviate when bending. A control panel 27 is fixedly installed on one side of the front end of the base 1. The control panel 27 facilitates the control of the operation of the equipment.

[0018] Working principle: When using this metal sheet bending equipment, the sheet metal is placed on the sliding plate 23, and then the limiting plates 24 on both sides of the sliding plate 23 correct and limit the sheet metal to ensure that the sheet metal does not deviate during bending. At this time, the sliding plate 23 is pushed to bring the sheet metal closer to the bending die 19, and then the sheet metal is pushed onto the bending die 19, which facilitates the bending of the sheet metal and provides convenience for the operator. The hydraulic push rod 9 pushes the mounting plate 7 to move, thereby driving the bending cutter 8 to move downward, thus bending the sheet metal. The material is bent, and with the cooperation of the sliding sleeve 5, guide rod 4 and shock-absorbing spring 6, the impact and vibration generated when the bending cutter 8 falls can be eliminated, avoiding displacement or springback deviation of the plate due to vibration, and ensuring that the angle and size of each bend are consistent. By pulling the pull ring 18 on one side of the T-shaped slide rail 10, the pull rod 17 is moved, causing the pressure plate 14 to move, causing the chamfering block 16 to disengage from the slot 13. Thus, according to the processing requirements of different bending angles, the equipment can quickly switch the corresponding mold, thereby shortening the mold change time.
