Description

Technical Field

[0001] This utility model relates to the field of hydraulic press equipment technology, specifically a hydraulic press with impact correction function. Background Technology

[0002] A hydraulic press is a machine that uses liquid as its working medium and is designed based on Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the press itself, the power system, and the hydraulic control system.

[0003] Hydraulic presses can be categorized into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses. They can be used for various processing techniques such as punching, stretching, bending, flanging, and cold extrusion of metal materials. In addition to forging, hydraulic presses can also be used for straightening, pressing, packaging, briquetting, and pressing plates, making them widely applicable.

[0004] According to the survey, existing hydraulic presses generally consist of three parts: the machine itself, the power system, and the hydraulic control system, and are used to process various processes.

[0007] This will lead to the following drawbacks:

[0008] The existing hydraulic presses do not have a clamping and stabilizing device. If a V-shaped bend needs to be straightened, it is easy for the bend to move left, right, forward, or backward. If it is manually supported and fixed, it will cause dimensional deviations, and fixing it by hand can easily cause danger.

[0009] In summary, this application proposes a hydraulic press with impact correction function to solve the aforementioned problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, it should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a hydraulic press with impact correction function includes a main body 14, which is a cuboid with a slot running through it, dividing the main body 14 into two parts, so that the top and lower half of the main body 14 are in a suspended state. A hydraulic cylinder 1 is provided on the top of the main body 14, and a pressure plate 2 is fixedly connected to the piston rod of the hydraulic cylinder 1. The pressure plate 2 is a cuboid and is used to squeeze the items. A platform 8 is provided on the main body 14 for placing the items to be squeezed. A correction component is also provided on the main body 14 to stabilize the items to be squeezed.

[0030] In further detail, the corrective components include: a first push plate 16, a second push plate 10, a first spring 17, a second spring 11, a first baffle 12, a second baffle 18, a first tension spring 13, a second tension spring 19, a second telescopic rod 15, a first support rod 20, a second support rod 21, and a first telescopic rod 22. Specifically, a fixed plate 9 is fixedly connected to the bottom of the platform 8. A groove is opened in the middle of the fixed plate 9, and the groove is circular and extends through the interior of the fixed plate 9. A first telescopic rod 22 is provided in the groove. A first support rod 20 is slidably installed inside the first telescopic rod 22. A first tension spring 13 is fixedly installed on the top of the first support rod 20. A first baffle 12 is fixedly connected to the other end of the first tension spring 13. A first spring 17 is fixedly connected to the side of the first baffle 12. The other end of the first spring 17 is fixedly connected to the first push plate 16.

[0031] Specifically, a second telescopic rod 15 is also provided in the groove. The bottom of the second telescopic rod 15 is fixedly connected to the bottom of the first telescopic rod 22. The telescopic directions of the two are opposite. A second support rod 21 is slidably installed inside the second telescopic rod 15. A second tension spring 19 is fixedly installed on the top of the second support rod 21. A second baffle 18 is fixedly connected to the other end of the second tension spring 19. A second spring 11 is fixedly connected to the side of the second baffle 18. A second push plate 10 is fixedly connected to the other end of the second spring 11. The movement principle of the straightening component is explained in detail: When the bent pipe that needs to be straightened is placed on the platform 8, it is clamped and stabilized by the first push plate 16 and the second push plate 10. When the pressure plate 2 is pressed down, the bent pipe can be straightened, and the straightened part... It will extend to both sides. The first push plate 16 and the second push plate 10 extend to both sides under the contraction force of the first spring 17 and the second spring 11. If it encounters a long bend, the first push plate 16 and the second push plate 10 will continue to extend to both sides, which can drive the first tension spring 13 and the first baffle 12, as well as the second tension spring 19 and the second baffle 18 to extend outward. Secondly, the other end of the first tension spring 13 that is not connected to the first baffle 12 is fixedly connected to the first support rod 20. The first support rod 20 can be extended by the first telescopic rod 22. The other end of the second tension spring 19 that is not connected to the second baffle 18 is fixedly connected to the second support rod 21, and the second support rod 21 can be extended by the second telescopic rod 15.

[0032] It should be noted that there is a gap between the first push plate 16 and the second push plate 10 and the fixed plate 9.

[0033] At least one quadrangular prism 5 is fixedly installed on the side of the top of the main body 14 (four are installed in this utility model). A sliding sleeve 6 is slidably fitted onto the quadrangular prism 5. A fixing rod 7 is fixedly connected to the outside of the sliding sleeve 6. The fixing rod 7 has an L-shaped structure, and the other end of the fixing rod 7 is fixedly connected to the pressure plate 2. The purpose is to provide a supporting force during the pressing of the pressure plate 2, so as to better support and stabilize the force of the pressure plate 2.

[0034] At least one protective plate 3 is installed on the main body 14. The protective plate 3 can be installed on the front, back, left and right sides of the main body 14. The protective plate 3 has a U-shaped structure and multiple holes on the side. Bolts 4 are threaded on the outside of the protective plate 3. Specifically, there are four bolts 4, one on each side of the protective plate 3. The bolts 4 pass through the protective plate 3 and can be detachably installed on the top of the main body 14 and the side of the shelf 8. Their function is to fix the position of the protective plate 3 and prevent the danger caused by the items splashing out during the squeezing process.

[0035] The working principle of this utility model is as follows:

[0036] Place the bent tube to be extruded horizontally on the platform 8 with the bent part facing upwards. Secure it in place using the first push plate 16 and the second push plate 10. Activate the hydraulic cylinder 1; the piston rod of the hydraulic cylinder 1 drives the pressure plate 2 downwards. When the pressure plate 2 presses down on the bent part, it straightens the tube. The straightened part extends outwards via the first spring 17 and the second spring 11, releasing the straightened length of the tube. If a longer tube is encountered, when the force of the first spring 17 and the second spring 11 reaches its maximum, it will press against the first tension spring 13 and the second tension spring 19, extending the first baffle 12 and the second baffle 18 outwards. The first support rod 20 and the second support rod 21 on the first telescopic rod 22 and the second telescopic rod 15 can further extend the length. This method stabilizes the position of the bent tube, preventing it from shifting during the extrusion process and minimizing dimensional deviations. It avoids inconsistent extruded dimensions caused by positional shifts, which can affect the wear and tear of the bent tube itself. Dimensional deviations can also lead to incorrect pressing positions, causing damage to parts and increasing costs.
