Description

Technical fields:

[0001] This application relates to the field of bending equipment technology, and in particular to a bending machine suitable for forging blanks. Background technology:

[0002] Utility model patent application number CN202223110225.1—A rigging hook ring bending machine—includes a base plate, with legs at the bottom of the base plate and support rods at the four corners of the top of the base plate. A top plate is located at the end of each support rod away from the base plate, and a lifting mechanism is mounted on the top plate. A pressure wheel is located at the bottom of the lifting mechanism. A drive mechanism is mounted on the base plate, and two symmetrically arranged T-shaped tracks are provided on the base plate. Two symmetrically arranged fixed wheels are mounted on the two T-shaped tracks. This utility model's rigging hook ring bending machine places the rigging hook material on the fixed wheels. The lifting mechanism drives the pressure wheel to bend the rigging hook. The drive mechanism allows adjustment of the position of the two fixed wheels, enabling adjustment of the bending angle for rigging hooks of different sizes. It offers high bending efficiency and strong flexibility.

[0003] This patent uses a lead screw with positive and negative leads to move two fixed wheels closer or further apart, which can adjust the position of the two fixed wheels to meet the bending requirements of shackle-type rigging with symmetrical structure. However, it cannot meet the bending requirements of safety hook-type rigging with asymmetrical structure. Moreover, the product after bending is pressed tightly against the outside of the punch, making it difficult to remove. Utility model content:

[0004] To solve the above-mentioned technical problems, this utility model provides a bending machine suitable for forging blanks. The technical problem it solves is that bending machines for shackle-type rigging and safety hook-type rigging are not interchangeable, and the bent product is pressed tightly against the outside of the punch, making removal difficult. To solve these problems, the technical solution adopted by this utility model is:

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0036] A bending machine suitable for forging blanks includes an operating table 1. The operating table 1 has a sliding plate 2, which is connected to the operating table 1 via a cylindrical linear guide rail. An X-axis power component 3 for driving the sliding is connected to one side of the moving plate 2 and is connected to the operating table 1. The moving plate 2 has a groove 4, and several horizontal threaded holes 12 are spaced apart on the side walls of the moving plate 2 on both sides of the opening of the groove 4. Two mounting seats 5 are connected to the moving plate 2 via horizontal bolts 15 engaging with the horizontal threaded holes 12. A pressure roller 6 is provided inside the mounting seat 5. A punch 7 is fixedly installed on the operating table 1 between the two mounting seats 5. The positions of the two pressure rollers can be adjusted according to the bending requirements, which can meet the bending of symmetrical structure products such as shackles and asymmetrical structure products such as safety hooks, thus reducing the cost of equipment procurement.

[0037] It should be noted that the movable plates 2 on both sides of the groove 4 are provided with slots 9. The two slots 9 are provided with adjusting bolts 10 on opposite side walls by thread engagement, which can limit the mounting base 5 and prevent the bolts 15 from being damaged by large shearing forces.

[0038] Furthermore, the adjusting bolt 10 is provided with a positioning nut 11 by means of thread engagement. By engaging the adjusting bolt 10 with the moving plate 2 and with the nut, the adjusting bolt 10 is prevented from loosening.

[0039] It should be noted that the horizontal threaded hole 12 is formed on the side wall of the slot 9 on both sides of the groove 4; the mounting base 5 is provided with a limiting groove 13 that engages with the slot 9, and the limiting groove 13 fits against the moving plate 2, thus limiting the mounting base 5. In addition, the mounting base 5 is also provided with a sliding groove 14 through which the screw of the horizontal bolt 15 passes, thereby improving the adjustment range of the mounting base 5 in the Z direction.

[0040] It should be noted that the left mounting base 5 has several vertical threaded holes 16 spaced apart, and a baffle 17 is provided on the left mounting base 5. The baffle 17 is connected to the left mounting base 5 through the engagement of vertical bolts with the vertical threaded holes 16. The right mounting base 5 is provided with a sliding push block 18 and a Z-axis power component 19 for driving the moving push block 18. The moving push block 18 presses the blank against the baffle 17 to align the blank and improve bending accuracy. It can also be used for blanks of different specifications to meet different placement space requirements, thus improving practicality.

[0041] The operating table 1 is also provided with a unloading mechanism 8 to push out the forging blank bent outward from the punch 7. The unloading mechanism 8 includes a U-shaped groove 81 opened around the punch 7. A U-shaped block 82 is provided in the U-shaped groove 81 in a sliding structure. The operating table 1 is provided with a Y-direction power member 83 for driving the U-shaped block 82 to move vertically up and down.

[0042] It should be noted that the side wall of the punch 7 is provided with a support block 84 in a vertical sliding structure. The support block 84 is fixedly connected to the U-shaped block 82 and slidably connected to the punch 7.

[0043] Specifically, the X-axis power component 3, the Y-axis power component 83, and the Z-axis power component 19 are all hydraulic cylinders. The operating platform 1 on one side of the X-axis hydraulic cylinder 3 and the Y-axis hydraulic cylinder 83 is equipped with a mounting plate with a sliding groove in a fixed structure. Two position sensors are installed in the sliding groove of the mounting plate. The output shaft of the X-axis power component 3 and the Y-axis power component 83 is equipped with sensing bolts. Through the cooperation of the sensing bolts and the position sensors, an electrical signal is transmitted to the controller, which then controls the reciprocating extension and retraction of the hydraulic cylinders. The two extreme positions of the X-axis and Y-axis hydraulic cylinders can be adjusted through the position sensors.

[0044] It should be noted that different models and specifications of punches 7 can be replaced according to different production needs to meet the bending requirements of different products.

[0045] The working principle and process of this utility model are as follows:

[0046] First, adjust the positions of the mounting base 5 and the baffle 17 according to the bending processing requirements of the product. Adjust the Z-direction position of the two pressure rollers 6 relative to the punch 7. Then tighten the horizontal bolt 15 to fix the mounting base 5 on the moving plate 2. Then rotate the adjusting bolt 10 so that the adjusting bolt 10 is pressed against the side wall of the mounting base 5. Then rotate the positioning nut 11 to the side wall of the slot 9.

[0047] Adjust the position of the baffle 17 according to the length of the blank and the placement requirements, and then fix it to the mounting base 5 with vertical bolts.

[0048] After adjustment, place the blank on the mounting base 5, activate hydraulic cylinder 19 to push the blank so that its left side abuts against baffle 17. At the same time, activate hydraulic cylinder 3 to push moving plate 2, mounting base 5, and blank towards punch 7. Pressure roller 6 pushes the blank, causing it to bend due to the obstruction of punch 7. After bending is completed, activate hydraulic cylinder 83 to extend. The output shaft of hydraulic cylinder 83 drives support block 84 upward through U-shaped block 82, thereby pushing out the bent blank pressed against the outer periphery of punch 7, completing the unloading operation.
