Description

Technical Field

[0001] This utility model relates to the field of forging hydraulic press technology, and in particular to a vertical pressure combination structure. Background Technology

[0002] As an indispensable key piece of equipment in modern industrial production, forging hydraulic presses use hydraulic oil and other liquids as working media. Through a hydraulic pump, mechanical energy is converted into liquid pressure energy. In a closed hydraulic system, liquid pressure can be transmitted uniformly and consistently in all directions. In forging production, vertical pressure is a key factor affecting the quality of forgings and production efficiency.

[0003] The vertical pressure assembly structure of the forging hydraulic press consists of a hydraulic rod, a slider, and a die. The hydraulic cylinder pushes the slider to reciprocate vertically along the guide rail, thereby generating vertical pressure, which is then transmitted to the die through the slider. Traditional die assembly methods rely solely on bolts to fix the die to the slider. However, during the forging process, due to the huge impact force and vibration generated by the hydraulic press, the die is prone to loosening and displacement, which will affect the quality of the forging. Therefore, we provide a vertical pressure assembly structure. Utility Model Content

The pressure application component 3 includes a hanging plate 301 disposed above the slider 1, on which a main hydraulic cylinder 302 is mounted, and the telescopic end of the main hydraulic cylinder 302 is connected to the upper surface of the slider 1. Two sets of symmetrically arranged auxiliary hydraulic cylinders 303 are mounted on the hanging plate 301, and the telescopic ends of the auxiliary hydraulic cylinders 303 are connected to the upper surface of the slider 1. By utilizing the coordinated work of the main hydraulic cylinder 302 and the auxiliary hydraulic cylinders 303, vertical pressure can be applied to the slider 1. The vertical pressure is transmitted to the forging work through the mold 2, thereby realizing the forging work. Furthermore, the coordinated work of the main hydraulic cylinder 302 and the auxiliary hydraulic cylinders 303 greatly improves the efficiency and accuracy of pressure output, ensuring stable and efficient pressure output throughout the forging process.

[0032] Second Embodiment

[0033] As attached Figure 1 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 With appendix Figure 7 As shown: Positioning component 4 is disposed outside the mold 2 and connected to the bottom surface of the slider 1. It includes connecting structures disposed on the left and right sides of the mold 2. The connecting structures of positioning component 4 include connecting plates 401 disposed on the left and right sides of the mold 2. Each connecting plate 401 is provided with a fixing plate 402 above it, and the upper surface of the fixing plate 402 is connected to the bottom surface of the slider 1. Each connecting plate 401 and each fixing plate 402 are connected by a set of bolts 403. The connecting plate 401 can be fixed to the fixing plate 402 by the bolts 403, thereby stably installing the mold 2 under the slider 1 and positioning the left and right sides of the mold 2.

[0034] The positioning structure of the positioning component 4, which is located on the front and rear sides of the mold 2, includes connecting screws 404 on the front and rear sides of each fixed plate 402. Each set of connecting screws 404 is fitted with a clamping plate 405. Each clamping plate 405 has a set of abutting blocks 406 on the side that is close to each other. Each connecting screw 404 is threaded with a nut 407. By using the connection between the nut 407 and the connecting screw 404, the clamping plate 405 will push the abutting block 406 to contact the mold 2, thereby forming a positioning reinforcement on the front and rear sides of the mold 2.

[0035] Two fixed plates 402 are fixedly connected to a hanging frame 408 on their opposite sides. Each hanging frame 408 has a hanging plate 409 slidably connected to its inner wall. The ends of each set of hanging plates 409 that are close to each other are connected to the left and right ends of each clamping plate 405. By using the cooperation between the hanging frame 408 and the hanging plate 409, the clamping plate 405 can be prevented from separating from the connecting screw 404, making it convenient for workers to tighten the clamping plate 405.

[0036] Each connecting screw 404 has a square groove 410 at its other end. A square block 411 is snapped into the inner wall of each square groove 410. A hexagonal cap 412 is fixedly connected to the other end of each square block 411. The hexagonal cap 412 is fitted onto the outside of the nut 407. The connection between the square block 411 and the square groove 410 can stabilize the hexagonal cap 412. The hexagonal cap 412 is fitted onto the outside of the nut 407 to stabilize it and prevent the nut 407 from loosening or falling off due to vibration.

[0037] Each clamping plate 405 has a support plate 413 fixedly connected to its bottom surface, and each support plate 413 has a mounting plate 414 overlapping its top surface. The two mounting plates 414 are connected to the front and rear sides of the mold 2 respectively on their side surfaces. When the clamping plate 405 moves, the support plate 413 will be moved synchronously to the bottom of the mounting plate 414, which can support the mounting plate 414 and further distribute the weight of the mold 2 borne by the connecting plate 401.

[0038] Third Embodiment

[0039] As attached Figure 1 With appendix Figure 2 As shown: Two sets of symmetrically arranged guide posts 5 are provided on the slider 1. The top of each guide post 5 is connected to the bottom surface of the hanging plate 301. A reinforcing plate 6 is fixedly connected to the outer surface of each set of guide posts 5. The guide posts 5 can guide the slider 1 and the mold 2 smoothly, ensuring that the mold 2 is subjected to vertical pressure, thereby ensuring the quality of forging. At the same time, the reinforcing plate 6 can further reinforce the connection between the guide posts 5, thereby ensuring the guiding effect of the guide posts 5.

[0040] The bottom surface of the slider 1 is provided with a positioning groove 7, and the top of the mold 2 extends into the interior of the positioning groove 7. The positioning groove 7 can be used to position the top of the mold 2, further improving the positioning effect of the mold 2 and making it easier for workers to install the mold 2.

[0041] Working principle: When in use, the top of the mold 2 is inserted into the positioning groove 7. Then, the connecting plate 401 and the fixing plate 402 are connected by bolts 403. Next, the clamping plate 405 is pushed so that the supporting block 406 contacts the mold 2. Then, the nuts 407 on the outside of the connecting screw 404 on the same side are tightened synchronously. The nuts 407 will apply a pushing force to the clamping plate 405, and the clamping plate 405 will push the supporting block 406. As the nuts 407 are gradually tightened, the pressure of the supporting block 406 on the mold 2 will continue to increase until it forms a stable support for the mold 2. This can effectively prevent the mold 2 from shifting when subjected to impact and vibration during the forging process, thereby ensuring the quality of the forging of the forging parts by the mold 2.
