Description

Technical Field

[0001] This invention belongs to the field of bearing forging preforming technology, specifically relating to a bearing forging preforming forging equipment and its forging method. Background Technology

[0002] Forging equipment refers to the mechanical equipment used for forming and separating in forging processes. Forging equipment includes forging hammers, mechanical presses, hydraulic presses, screw presses, and flat forging machines for forming, as well as auxiliary equipment such as forging manipulators, uncoilers, straighteners, and shearing machines. Forging equipment is mainly used for metal forming, hence it is also called metal forming machine tools. Forgings are workpieces or blanks obtained by forging and deforming metal billets. By applying pressure to metal billets to induce plastic deformation, their mechanical properties can be altered. In the current bearing forging process, different limiting rings need to be replaced and fixed according to different bearing models, requiring repositioning. The entire process involves too much manual intervention, resulting in reduced efficiency and certain safety hazards. There is no better adjustment structure that allows for processing of multiple models in a single positioning. Summary of the Invention

[0009] A limiting groove is formed at one end of the sphere that is perpendicular to the plane of the limiting ring body, and a limiting component is slidably provided inside the limiting groove. Two threaded rods are fixed at both ends of the limiting component.

[0010] The limiting component includes a first limiting block and a second limiting block, which are separated by the outward stretching of two threaded rods.

Safety nets are provided on both the front and rear sides of the base to provide safety protection for the installation cavity area.

[0018] A forging method for a bearing forging preforming forging equipment, the specific steps of which are as follows:

[0019] S1. Model selection: Rotate the appropriate limit ring body among multiple limit ring bodies according to the requirements;

[0020] S2, Limit Adjustment: Start the motor to drive the drive wheel to rotate, which in turn drives the driven wheel to rotate. The driven wheel is connected to the threaded rod, which pulls the first limit block to move outward. The other end is driven by the synchronous drive of the pulley to move the second limit block to the other side.

[0021] S3. Rotation positioning: Based on S2, after the first and second limit blocks are moved to the sides, the limit ring body can be manually rotated, and then the limit ring body selected in S1 is placed directly below the mounting bracket.

[0022] S4. Limit Locking: Based on S2, the reverse motor drives the threaded rod to push the first limit block and the second limit block to reset. During this process, whether the four corners of the limit component can be accurately inserted can be determined by whether the limit ring body exposed on the top surface of the base is horizontal. A level or infrared laser detection can be installed.

[0023] S5. After processing and shaping, the mounting bracket is activated to act on the limit ring body to process the bearing forging.

[0024] The technical effects and advantages of this invention are as follows: 1. The starting motor drives the driven wheel to rotate. The driven wheel is connected to the threaded rod, which pulls the first limiting block to move outward. The other end is driven by the synchronous drive of the pulley to move the second limiting block to the other side. Based on S2, after the first and second limiting blocks are moved to the sides, the limiting ring body can be manually rotated. Then, the limiting ring body selected in S1 is placed directly below the mounting frame. Based on S2, the reverse motor drives the threaded rod to push the first and second limiting blocks to reset. During this process, whether the four corners of the limiting parts can be accurately inserted can be determined by whether the limiting ring body exposed on the top surface of the base is horizontal. A level or infrared laser detection can be used. Finally, the mounting frame is started to act on the limiting ring body to process the bearing forging. The whole process can realize the direct use of multiple models after one calibration. The lower support structure is also a solid support, so there will be no shaking or other issues. The safety is high and the work efficiency will be greatly improved.

[0025] 2. Due to the different sizes of each limiting ring body, the mounting surfaces are also different. When the larger limiting ring body is in the machining position, the bottom of the smaller limiting ring body, along with the remaining solid positions, achieves automatic adjustment of the support area generated by this structure to adapt to and increase the machining stability of the bearing forging. Then, by utilizing the contraction of the elastic shrinkage component, when the forging limiting ring adjustment component rotates, the electromagnet installed at the end of the spring away from the second slider attracts the limiting ring body to move inward, facilitating the rotation and adjustment of the forging limiting ring adjustment component. After adjustment, it extends and is then fixed. The base also has two cavities opened according to the volume of the largest limiting ring body to temporarily store the limiting ring body. The shape of the slide rod and the slide groove can be... Figure 9 As shown, it can also be directly slid-fitted without limit, that is, without the gap between the slide groove and the slide rod in the figure, and the extension distance is controlled by the movement of the threaded rod to prevent disengagement.

[0041] The limiting member 16 includes a first limiting block 1601 and a second limiting block 1602 that are separated by being stretched outward by two threaded rods 15. A linear guide assembly is provided between the first limiting block 1601 and the second limiting block 1602, and the installation position of the linear guide assembly does not affect the extension and rotation of the limiting ring body 601.

[0042] Specifically, the sphere 602 has several moving grooves 605 inside, and two are arranged in a group on both sides of several limiting ring bodies 601. The elastic contraction component 604 includes a second slider 6041 fixed to the outside of the limiting ring body 601, and a spring 6042 is connected between the second slider 6041 and the sphere 602. An electromagnet is installed at the end of the spring 6042 away from the second slider 6041 to attract the second slider 6041 and drive the limiting ring body 601 to move inward.

[0043] Specifically, the linear guide assembly includes a slide rod 1604 that is slidably disposed between the first limiting block 1601 and the second limiting block 1602. The first limiting block 1601 and the second limiting block 1602 each have a slide groove 1603 on opposite sides inside for the slide rod 1604 to slide.

[0044] Specifically, the sphere 602 rotates after all the limiting ring bodies 601 except the maximum limiting ring body 601 retract into the sphere 602. This rotation can be done manually.

[0045] Specifically, the power assembly includes a drive wheel 13 that meshes with the driven wheel 8. The drive wheel 13 is connected to an external motor 12 for power transmission. The motor 12 is mounted on the base 5 using an L-shaped plate.

[0046] Specifically, the synchronization component includes a side shaft 9 disposed inside the base 5. Both ends of the side shaft 9 are provided with pulleys 2. The pulleys 14 move synchronously with the pulleys 2 via the timing belts 10 and are transmitted to the other side.

[0047] Specifically, the mounting frame 2 includes a side frame 201 mounted on one side of the base 5. A mating frame 202 is mounted on the side frame 201, and one end of the mating frame 202 extends to the position directly above the forging limit ring adjustment component 6. A frame 203 is fixed to the mating frame 202 at the position directly above the forging limit ring adjustment component 6. A forming power output device 204 is provided inside the frame 203. The bottom of the forming power output device 204 is fixed to the base 205, and the outer edge of the base 205 is fixedly connected to the frame 203.

The output shaft of the forming power output device 204 extends to the bottom of the base 205 and is fixedly connected to the limit ring mating mold 206.

[0048] Specifically, a guide platform 4 is fixed on the upper surface of the base 5 at the top of the forging limit ring adjustment assembly 6. The guide platform 4 is located directly above the forging limit ring adjustment assembly 6 and has a guide groove for easy positioning. Safety nets 1 are provided on both the front and rear sides of the base 5 to provide safety protection for the installation cavity 7 area.

[0049] Working principle: According to requirements, a suitable limiting ring body 601 is rotated among multiple limiting ring bodies 601. The starting motor 12 drives the driving wheel 13 to rotate, which in turn drives the driven wheel 8 to rotate. The driven wheel 8, internally connected to the threaded rod 15, pulls the first limiting block 1601 outwards. Simultaneously, the pulley 14 drives the second limiting block 1602 to move to the other side. Based on step S2, after the first and second limiting blocks 1601 and 1602 move apart, a person can... The worker rotates the limiting ring body 601, and then places the limiting ring body 601 selected in S1 directly below the mounting bracket 2. Based on S2, the reverse motor 12 drives the threaded rod 15 to push the first limiting block 1601 and the second limiting block 1602 to reset. During this period, whether the four corners of the limiting member 16 can be accurately inserted can be determined by whether the limiting ring body 601 exposed on the top surface of the base 5 is horizontal. A level or infrared laser detection can be installed. Finally, the mounting bracket 2 is started to act on the limiting ring body 601 to process the bearing forging.

[0050] Example 2: Based on Example 1, utilizing the design of the elastic contraction component 604, the entire forging limit ring adjustment component 6 can rotate to open the inner cavity along the edge of the largest limit ring body 601. Since the bearing forgings have similar heights, the smaller limit ring bodies 601 are equipped with corresponding mounting platforms to ensure sufficient contact support at the bottom during the forming of the large limit ring body 601. Figure 6 As shown, each limiting ring body 601 has a different size and a different mounting surface. When the larger limiting ring body 601 is in the machining position, the bottom of the limiting ring body 601 is smaller, and the remaining solid position angle realizes the automatic adjustment support area generated by this structure to adapt to the increased machining stability of the bearing forging. Then, by utilizing the contraction of the elastic contraction component 604, when the forging limiting ring adjustment component 6 rotates, the electromagnet installed at the end of the spring 6042 away from the slider 6041 attracts the limiting ring body 601 to move inward, which facilitates the rotation and adjustment of the forging limiting ring adjustment component 6. After the adjustment is determined, it extends and is fixed. The base 5 also has two cavities opened according to the volume of the largest limiting ring body 601 to temporarily store the limiting ring body 601. The shape of the slide rod 1604 and the slide groove 1603 can be Figure 9 As shown, it can also be directly slid-plugged with an unlimited number of positions, that is, without... Figure 9 The gap between the slide groove 1603 and the slide rod 1604 is controlled by the movement of the threaded rod 15 to extend the distance and prevent it from disengaging.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
