Description

Technical Field

[0001] This utility model relates to the field of wheel spoke steel ring processing technology, specifically a thousand-newton hydraulic press for straightening. Background Technology

[0002] When processing the spoked steel rim, it needs to be corrected. The flared rim is fitted onto the lower mold, and the upper mold is driven to move downward. At this time, the moving blocks of the upper and lower molds move axially away from the center of the mold until the upper mold and the lower mold abut together, thus completing the rim shape correction.

[0003] The existing equipment requires manual placement of the wheel hub on the straightening base film during use. It is then straightened and shaped by pressing with upper and lower molds. After shaping, it is manually pulled out. The operator's hands need to be close to the straightening and pressing parts to pick it up. When it is difficult to make protective adjustments on the outside, there is a certain safety hazard if the operator makes an operational error, which affects the efficiency of the equipment. This needs to be optimized and improved. Utility Model Content

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a correction hydraulic press with a kN, including: a support plate 1, a power box 2 installed on one side of the support plate 1, and a bottom support frame 3 connected to the top of the support plate 1;

[0025] Specifically, such as Figure 1 As shown, a lower mold support block 4 is provided at the top of the bottom support frame 3, and a moving block 5 is provided at the top of the lower mold support block 4. There are multiple moving blocks 5. When the wheel hub is straightened, the moving blocks 5 in the axial direction move away from the center of the mold to squeeze and straighten the inner side of the wheel hub.

[0026] Specifically, such as Figure 1 As shown, guide rods 6 are connected to the top four corners of the bottom support frame 3. The top of the guide rods 6 is equipped with an upper mounting frame 14. The guide rods 6 are used for the fixed support of the upper mounting frame 14 and also facilitate the sliding limit of the moving module.

[0027] Specifically, such as Figure 2 As shown, a fixed plate 7 is connected to the top of the power box 2, and a telescopic cylinder 8 is connected to the top of the fixed plate 7. The ejector plate 9 is set at the top of the telescopic cylinder 8. The extension and descent of the telescopic cylinder 8 controls the position of the ejector plate 9, and the sliding block 10 slides on the outside of the guide rod 6 to improve the stability of the ejector plate 9.

[0028] Specifically, such as Figure 2 As shown, a vision sensor 11 is installed at the top front end of the bottom support frame 3, and a telescopic rod 12 is connected to the bottom front end of the bottom support frame 3. A baffle 13 is connected to the front end of the telescopic rod 12. The vision sensor 11 is used to monitor the processing position during the processing process to prevent workers from operating before the processing is completed. Before stopping the machine, the telescopic rod 12 is in the extended state, and the baffle 13 is set to limit the range of workers' standing.

[0029] The bottom support frame 3 is provided with an ejection adjustment assembly on its outer side. The ejection adjustment assembly includes an ejection plate 9, and a movable slider 10 is provided on the outer side of the ejection plate 9. A baffle 13 is provided at the front end of the ejection plate 9. The ejection adjustment assembly is used to correct the ejection of the rear wheel hub.

[0030] The bottom support frame 3 is provided with a pressure adjustment component at its top. The pressure adjustment component includes a telescopic cylinder 2 15, and a rotating positioning block 18 is provided at the bottom end of the telescopic cylinder 2 15. A positioning seat 20 is provided on the outside of the rotating positioning block 18, and an upper pressure module 23 is provided at the bottom end of the positioning seat 20. The pressure adjustment component is used for the correction and adjustment of wheel hubs with different widths.

[0031] Specifically, such as Figure 3 As shown, the telescopic cylinder 2 15 is connected to the inner top of the upper mounting frame 14, and the bottom end of the telescopic cylinder 2 15 is connected to the connecting plate 16. The top four corners of the connecting plate 16 are connected to elastic connecting rods 17. The telescopic cylinder 2 15 drives the connecting plate 16 to rise and fall. The connecting plate 16 is connected to the inner side of the upper mounting frame 14 through the elastic connecting rods 17 for guidance, buffering and protection.

[0032] Specifically, such as Figure 4 As shown, the rotating positioning block 18 is connected to the bottom end of the connecting plate 16, and the inner side of the rotating positioning block 18 is provided with a positioning hole 19, which is used for connecting the rotating positioning block 18.

[0033] Specifically, such as Figure 4 As shown, the inner side of the positioning seat 20 is provided with a rotating slot 21, and the top of the positioning seat 20 is connected with a fastening screw 22. The bottom of the positioning seat 20 is connected with an upper pressure module 23. After the rotating positioning block 18 is inserted into the rotating slot 21, it rotates 90 degrees. Then, the rotating positioning block 18 and the positioning seat 20 are fixed by fastening screw 22. The upper pressure module 23 can be replaced according to actual needs.

[0034] In this embodiment: a vision sensor 11 is set to detect the position, and then a baffle 13 is used to block it, which improves the safety of the wheel hub during the straightening and extrusion. The sliding adjustment of the ejector plate 9 driven by the moving slider 10 facilitates the automatic ejection of the wheel hub and reduces manual intervention. When straightening the wheel hub, the moving block 5 on the lower mold support block 4 and the upper pressure module 23 are required to cooperate in the extrusion to achieve the forming effect. In order to improve the processing range of the equipment, the upper pressure module 23 can be easily replaced by rotating the locking between the rotating positioning block 18 and the positioning seat 20.

[0035] The specific solution is as follows: When straightening the processed wheel hub, the wheel hub is first placed outside the ring-shaped moving block 5. Then, the telescopic rod 12 drives the baffle 13 to extend, limiting the operator's standing range and reducing safety hazards. Then, the top telescopic cylinder 2 15 drives the upper pressing module 23 to press down. At the same time as pressing down, both the moving block 5 and the upper pressing module 23 move away from the center of the mold, squeezing the side wall of the wheel hub to achieve the straightening effect. After straightening and forming, the telescopic cylinder 2 15 moves up. At this time, the bottom telescopic cylinder 1 8 drives the ejector plate 9 to slide, ejecting the straightened wheel hub. At this time, the baffle 13 retracts, making it easy for the operator to pick up. When it is necessary to straighten and adjust some wheel hubs with different structures and sizes, the fastening screw 22 is unscrewed, and then the upper pressing module 23 is rotated 90 degrees to separate the rotating positioning block 18 and the positioning seat 20 for replacement. The operation is convenient and can improve the processing efficiency of the equipment.
