Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of isothermal forging, in particular to an isothermal forging hydraulic press with protection function. BACKGROUND

[0002] Isothermal forging is a precision forging technology, its core feature is to keep the temperature of the mold and the billet in the same constant range, usually by heating the mold to make its temperature roughly the same as the billet heating temperature, so as to reduce or eliminate the temperature difference between the mold and the billet in the forming process. This process significantly reduces the deformation resistance of the material, improves the plasticity of the material, and makes the forming process more stable and efficient.

[0003] The Chinese invention patent with publication number CN101985150A discloses a hydraulic press with isothermal forging and electrode pressing composite function, which comprises: a combined frame type machine body composed of an upper cross beam, a lower cross beam and four columns, the upper cross beam is fixed with a return cylinder and a side cylinder, the return cylinder and the side cylinder are connected with a sliding block, the lower cross beam is provided with a moving workbench on the upper surface, characterized in that: an upper die installation groove is formed on the lower surface of the sliding block, and positioning holes and screw holes are formed on the lower surface of the sliding block; the moving workbench is provided with a fixed isothermal forging die installation groove and a pressing electrode block die installation groove on the upper panel corresponding to the position of the sliding block installation groove, a bracket is fixed at the rear end of the moving workbench, the bracket is provided with a die pushing cylinder, and a workpiece ejecting cylinder is installed in the lower cross beam. The advantages are: reducing the intermediate links in the process of electrode preparation and isothermal forging, matching the production capacity, reducing the transportation cost, saving raw materials and energy. It can be applied to the production of titanium raw materials to titanium isothermal forging terminal products for high-temperature alloy, titanium, zirconium alloy and other materials.

[0004] In addition, due to the relatively slow speed of manual feeding and discharging, especially in frequent and repetitive operations, workers are prone to fatigue, resulting in unstable feeding and discharging rhythm, which is difficult to meet the needs of high-speed stamping production. During the manual feeding and discharging process, the worker needs to put his hand into the working area of the stamping device. When the operation is wrong or the equipment fails, safety accidents such as hand clamping and hand pressing are likely to occur, causing serious harm to the worker's body. In addition, when manually feeding and discharging, the placement position and posture of the material may have some deviation, making it difficult to ensure the accuracy and consistency of each feeding and discharging. Such deviation may cause fluctuations in the size precision, shape precision and other quality indicators of the stamped parts, affecting the stability of product quality and increasing the scrap rate. Therefore, the hydraulic press with isothermal forging and electrode pressing composite function disclosed in the Chinese invention patent CN101985150A cannot guarantee the quality of the material hydraulic pressure and improve the efficiency of the material hydraulic pressure.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example:

[0036] See attached document Figures 1 to 9 As shown, an isothermal forging hydraulic press with protective functions includes a base 101, a support platform 102, and a hydraulic unit 103. The support platform 102 is fixedly connected to the top of the base 101, and the hydraulic unit 103 is fixedly installed on the inner side of the support platform 102.

[0037] The unloading mechanism 200 includes a collection box 201 fixedly connected to the side wall of the base 101, and an unloading assembly 202 disposed at the bottom of the hydraulic device 103;

[0038] The feeding mechanism 300 includes a storage box 301 fixedly connected to the side wall of the base 101, and a feeding assembly 302 disposed on the top of the storage box 301.

[0039] Furthermore, the feeding assembly 202 includes a filter plate 2031 fixedly connected inside the collection box 201, a fixing frame 2032 symmetrically fixedly connected to the upper surface of the base 101, a threaded rod 2033 rotatably connected between two fixing frames 2032 on the same side, a toothed plate 2034 symmetrically slidably connected to the bottom end of the support platform 102, the toothed plate 2034 has an electrical connection with the equipment control device, the bottom end of the toothed plate 2034 slides inside the base 101, a lever plate 2035 is slidably connected to the outer wall of the threaded rod 2033, and the threaded rod 2033 and the lever plate 2035 are threadedly connected.

[0040] Furthermore, the feeding assembly 202 also includes a gear 2036 fixedly connected to the outer wall of the threaded rod 2033, a gear plate 2034 meshing with the gear 2036, a processing table 2037 fixedly connected to the upper surface of the base 101, a guide inclined plate 2038 fixedly connected to the side of the processing table 2037 near the gear 2036, a fixing rod 2039 symmetrically fixedly connected to the bottom end of the support platform 102, a lever plate 2035 slidably connected to the fixing rod 2039, and a spring 20310 sleeved on the outer wall of the fixing rod 2039, with the two ends of the spring 20310 fixedly connected to the support platform 102 and the lever plate 2035 respectively.

[0041] It should be noted that during the downward movement of the toothed plate 2034, it can drive the two meshing gears 2036 to move in the opposite direction, so that the gears 2036 drive the threaded rod 2033 to rotate synchronously in the opposite direction, so that the lever plate 2035 can slide on the outer wall of the fixed rod 2039 under the elastic action of the spring 20310.

[0042] Furthermore, the feeding assembly 302 includes symmetrically sliding slide plates 3031 connected inside the storage box 301. The slide plates 3031 are electrically connected to the equipment control device. Fixing blocks 3032 are fixedly connected to the side walls of the two slide plates 3031. Fixing rods 3033 are fixedly connected between the two fixing blocks 3032. Fixing block 3034 is fixedly connected to the middle of the fixing rods 3033. A guide plate 3035 is fixedly connected to the outer wall of the toothed plate 2034. A groove 3036 is opened inside the toothed plate 2035. The middle of the groove 3036 is arc-shaped, and the extended parts at both ends of the groove 3036 are perpendicular to each other. A drive rod 3037 is rotatably connected through the middle of the guide plate 3035. The drive rod 3037 is electrically connected to the equipment control device.

[0043] Furthermore, the feeding assembly 302 also includes a connecting plate 3038 fixedly connected to the outer wall of the drive rod 3037 near the guide plate 3035. The connecting plate 3038 has a second sliding groove 3039 inside. A guide rod 30310 is slidably connected inside the first sliding groove 3036. The size of the end of the guide rod 30310 away from 3011 is adapted to the size of the first sliding groove 3036 and the second sliding groove 3039. A fixing rod 3 is rotatably connected to the end of the guide rod 30310 near the connecting plate 3038. 30311, fixed rod three 30311 slides inside gear rod 30314, fixedly connected to the bottom end of fixed rod three 30311 is magnetic suction plate 30312, magnetic suction plate 30312 has an electrical connection with equipment control device, gear two 30313 is fixedly connected to the outer wall of the end of drive rod 3037 away from fixed rod three 30311, gear rod 30314 is rotatably connected to the inner wall of slide plate 3031, gear rod 30314 and gear two 30313 mesh with each other.

[0044] It should be noted that the size of gear 2 30313 is smaller than the size of gear rod 30314, and the size of fixed rod 3 30311 is smaller than the area inside gear rod 30314 that can accommodate the sliding of fixed rod 3 30311.

[0045] The following describes the working process and principle of the above embodiments:

[0046] The initial state is as follows: Gear 2036 is at the bottom of gear plate 2034, spring 20310 is in a stretched state, and slide plate 3031 is at the top of storage box 301.

[0047] The work steps are as follows:

[0048] At the start of operation, the operator controls the drive rod 3037 to rotate via the equipment control device. This causes the drive rod 3037 to drive the gear 30313 and the connecting plate 3038 to rotate synchronously. The connecting plate 3038 then drives the slide groove 3039 to rotate synchronously. This causes the slide groove 3039 to slide downwards inside the slide groove 3036, contacting the guide rod 30310. The guide rod 30310 then slides towards the drive rod 3037 inside the slide groove 3039, which in turn causes the fixed rod 30311, which is rotatably connected to it, to move downwards synchronously. Simultaneously, as gear 2 30313 rotates, it drives gear rod 30314 to rotate synchronously, causing gear rod 30314 to rotate on the inner wall of slide plate 3031. This causes gear rod 30314 to contact fixed rod 30311 and rotate synchronously, thereby causing gear rod 30314 to contact 3011 and drive magnetic plate 30312 to move to a vertical position. Then, the operator controls slide plate 3031 to move vertically downward inside storage box 301 through the equipment control device, thereby causing 3012 to magnetically attract the metal plate stored inside storage box 301.

[0049] Subsequently, the sliding plate 3031 is moved vertically upward inside the storage box 301, causing the sliding plate 3031 to drive other structures inside the feeding assembly 302 to move vertically upward. Then, the operator controls the drive rod 3037 to rotate in the opposite direction on the inner wall of the sliding plate 3031 via the equipment control device. This causes the drive rod 3037 to move the second slide 3039 synchronously, causing the second slide 3039 to slide in the opposite direction inside the first slide 3036 against the guide rod 30310. This causes the connecting plate 3038 to move the fixing rod 30311 to one side of the bottom end of the first slide 3036 via the second slide 3039 and the guide rod 30310. Simultaneously, the drive rod 3037 drives the gear rod 30314 to rotate in the opposite direction via the second gear 30313, causing the gear rod 30314 to rotate against the fixing rod 30311. This causes the fixing rod 30311 to move... The drive rod 3037 moves in the same direction as the bottom of the slide 3036, thereby causing the guide rod 30310 to slide at the bottom of the slide 3036 via the connecting plate 3038 and the slide 3039. This causes the magnetic plate 30312 to move the magnetically attracted metal block to the top of the processing table 2037. Then, by adjusting the distance that the slide plate 3031 moves inside the storage box 301, the magnetic plate 30312 places the metal block on the top of the processing table 2037. Subsequently, the hydraulic unit 103 is controlled to perform hydraulic forming on the metal plate. The automatic feeding mechanism 300 can accurately control the placement position and posture of the material, ensuring the accuracy and consistency of each loading and unloading. This reduces the material positioning deviation caused by manual operation, improves the dimensional and shape accuracy of the product, reduces the scrap rate, and ensures the stability of product quality.

[0050] After the metal plate is hydraulically compressed, the operator controls the toothed plate 2034 to slide downwards inside the support platform 102. This causes the toothed plate 2034 to drive the meshing gear 2036 to rotate synchronously. The gear 2036 then drives the threaded rod 2033 to rotate on the inner wall of the fixed frame 2032. Since the spring 20310 is under tension, it has a certain degree of elasticity. As the threaded rod 2033 rotates, it can drive the threadedly connected dial plate 2035 to move towards the guide inclined plate 2038. This causes the dial plate 2035 to push the metal block and the compressed residue to move synchronously, so that the metal block moves along the guide inclined plate 2038. The residue falls into the collection box 201, and is filtered by the filter plate 2031, which then enters the bottom of the filter plate 2031. The metal plate is placed on the top of the filter plate 2031 for collection. The feeding mechanism 200 and the loading mechanism 300 automatically load and unload the metal plate, which can load and unload materials at a stable and fast pace, unaffected by fatigue, mood or other factors. This greatly shortens the processing cycle of a single workpiece and improves the overall production efficiency. In addition, workers do not need to put their hands into the dangerous area of ​​the stamping device, which effectively avoids safety accidents such as pinching or pressing hands caused by operational errors or equipment failures, and protects the personal safety of workers.
