The operator controls the axial distance between the left sliding column and the right sliding column by pushing the upper and lower positions of the horizontal push rod, thereby changing the size of the semicircle formed by the forming belt to achieve the matching of small-sized pipes, medium-sized pipes and large-sized pipes, and then through the upper mold and the lower mold, it is possible to realize the ability to process various types of materials.

[0003] In the related technology, the processing of existing special-shaped light-weight components generally requires corresponding hydraulic forging machines for forging processing.

With the driving of the two end pressure mechanisms 4, the light-weight component in the mold closing process can be hydraulically forged to finally form a special-shaped light-weight component. The setting of the unloading mechanism 8 is used to demold and unload the special-shaped light-weight component formed by hydraulic forging; The unloading mechanism 8 includes recesses opened on both sides of the fixed mold 3, and demoulding members 81 are arranged in the two recesses. A lifting member 82 for lifting and driving the two demoulding members 81 is arranged inside the workbench 1. By setting the lifting member 82, the demoulding members 81 in the two recesses can be lifted and driven, and then the special-shaped components located in the fixed mold 3 can be demoulded and unloaded by the two demoulding members 81, forming an automatic unloading operation without manual unloading, which solves the problem in the prior art that the special-shaped components are easily stuck in the mold and difficult to be removed when unloading is performed manually, thereby affecting the subsequent hydraulic forging efficiency; The feeding mechanism 9 includes a storage part 91 for storing light components and a feeding part 92 for transferring the light components stored in the storage part 91 to the interior of the fixed mold 3; By setting the storage part 91, the light-weight components that need hydraulic forging can be positioned and stored, and by setting the loading part 92, the positioned and stored light-weight components can be transported to the fixed mold 3, forming an automatic loading operation without manual loading. This solves the problem in the prior art that it is inconvenient to calibrate the position of the light-weight components when loading manually, thereby affecting the subsequent hydraulic forging effect, and the problem that dangers are prone to occur during manual loading.

[0019] See attached Figure 3 and Figure 4 The storage member 91 includes a conical hopper 911 fixed to the back of the workbench 1, the bottom of the conical hopper 911 is fixedly connected to an inclined material guide frame 912, and the bottom end of the material guide frame 912 is fixedly connected to a temporary storage plate 913; The conical hopper 911 is provided to store light components that require hydraulic forging, and the guide frame 912 is provided to orderly arrange the stored light components to the temporary storage plate 913 to facilitate the material removal work of the loading part 92.

The inclination angle can be set according to the actual situation. Figure 5 As shown; The guide rod 922 is moved along the track of the guide plate 921 by the driving member, and then the electric clamping member 924 holding the light component can be driven by the two L-shaped frames 923, so as to facilitate the loading of the light component in the storage position to the fixed mold 3 position, forming an automatic loading work, without manual loading, improving the convenience of operation and work efficiency; The electric clamping member 924 adopts a mechanism used in the prior art for electrically clamping pipe fittings; The electric clamping member 924 includes a crossbeam frame fixedly connected to the two L-shaped frames 923, and an arc-shaped electromagnet for adsorbing the metal pipe is fixedly connected to the bottom of the crossbeam frame.

[0023] Embodiment 2: Based on embodiment 1, the difference is that; See attached Figure 8 and Fig. 9 The demoulding member 81 includes a movable frame 811 slidably connected to the inside of the recess, and the top of the movable frame 811 is fixedly connected to an L-shaped bracket 812 through a bracket; The L-shaped bracket 812 is inclined so that when the L-shaped bracket 812 moves upward, it can not only lift up the special-shaped component formed in the fixed mold 3 to form a demolding operation, but also cooperate with its own inclined surface to make the special-shaped component automatically slide down after demolding to form an automatic unloading operation.

[0024] The lifting member 82 includes a rotating shaft 821 rotatably connected to the inside of the workbench 1 through a bracket, and circular plates 822 are fixedly connected to both ends of the rotating shaft 821, and convex rods 823 are fixedly connected to the outer sides of the two circular plates 822, and reciprocating frames 824 are sleeved on the outer surfaces of the two convex rods 823. The tops of the two reciprocating frames 824 are respectively fixedly connected to the two moving frames 811 through connecting frames 825, and a rotating member for rotating and driving the rotating shaft 821 is arranged inside the workbench 1; The rotating parts include but are not limited to electric motors. By driving the rotating shaft 821 to rotate, the two circular plates 822 can be driven to rotate. The rotation of the two circular plates 822 can drive the two protruding rods 823 to move in a circle with the rotating shaft 821 as the axis, and then drive the two reciprocating frames 824 to move up and down. Finally, the two demolding parts 81 can be driven up and down through two connecting frames 825 to form an automatic demolding and unloading operation.

[0025] Embodiment 3: Based on embodiment 1, the difference is that; See attached Fig. 9 The rotating member includes a gear 826 fixed to the outer surface of the rotating shaft 821 through a one-way bearing and a toothed plate frame 827 slidably connected to the bottom of the workbench 1, and the toothed plate frame 827 is meshed with the outer surface of the gear 826; The gear plate frame 827 can be driven to rotate by the forward and backward movement, and the rotating shaft 821 can be driven to rotate synchronously, thereby forming a lifting driving operation of the lifting member 82; The gear 826 is fixedly connected to the rotating shaft 821 by a one-way bearing, which not only facilitates the gear 826 to rotate through the one-way bearing when the toothed plate frame 827 pushes, but also facilitates the gear 826 not to rotate when the toothed plate frame 827 is reset, thereby avoiding that the feeding mechanism 9 will not drive the demoulding member 81 when it is reset after feeding, thereby ensuring the stability of the demoulding member 81 after reset; The length of the toothed plate frame 827 and the distance it pushes are just enough to drive the gear 826 to rotate a full circle, so that when the feeding mechanism 9 reaches the material discharging position from the material taking position, its rotating part just drives the demoulding part 81 to perform the lifting and resetting work; A transmission rod 828 is slidably connected to the back of the workbench 1, one end of the transmission rod 828 is fixedly connected to the toothed plate frame 827, and the other end of the transmission rod 828 is fixedly connected to the sliding frame 926; The toothed plate frame 827 is fixedly connected to the sliding frame 926 through the transmission rod 828, so that the toothed plate frame 827 can be synchronously driven by the feeding mechanism 9 during the loading process. It has a good linkage function, which not only facilitates the synchronous unloading work during the loading process, thereby improving the functionality and practicality of the equipment, but also reduces the use of electric drive sources, improves the energy-saving and environmental protection performance of the equipment and the orderliness of loading and unloading.
