Description

Technical Field

[0001] The invention belongs to the technical field of casting, and in particular relates to a vibrating device for casting on a hydraulic press workbench. Background Art

[0002] The workbench of a hydraulic press is an important component of a hydraulic press. It is usually driven by liquid pressure and is used to carry and fix the workpiece for various processing operations, such as calendering, stretching, bending, etc. The workbench of a hydraulic press can be designed to be fixed or mobile to meet different production needs. For example, some hydraulic presses are equipped with a mobile workbench, which makes it easy to install and remove large molds. In addition, the design of the workbench needs to consider its strength and rigidity to ensure that it can withstand the corresponding pressure without deformation during the processing. The selection of the size and pressure of the workbench of the hydraulic press is also very important, which directly affects the quality and precision of the processed parts. Common materials for the workbench of a hydraulic press include cast iron and steel plates. Cast iron workbenches are usually cast with gray cast iron or ductile iron, which are low-cost, easy to process and maintain. The casting of the workbench of a hydraulic press is a complex and delicate process. During this process, one of the key steps is to make the metal liquid of the casting workbench dense and uniform in quality through a vibrating device.

[0003] Since the modules that make up the workbench of the hydraulic press are generally large, a vibrating table is often used during casting. The disadvantage of this method is that the vibration path of the vibrating table is relatively single, which will cause the bubbles in the molten metal to be discharged more slowly. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a self-lubricating gear for machinery, which solves the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a vibrating device for casting on a hydraulic press workbench, comprising a bottom rail and a support frame, a support seat is fixedly installed on the upper surface of the support frame, a servo motor is fixedly installed on the upper surface of the support seat, a driving wheel is fixedly connected to the output end of the servo motor, a fixing rod is fixedly connected to the upper surface of the support frame, a driven wheel is rotatably installed on one side of the fixing rod, a transmission belt is sleeved on the surface of the driven wheel and the driving wheel, a support rod is fixedly connected to the surface of the transmission belt, and a trapezoidal rod is fixedly connected to one side of the support rod;

[0006] The upper surface of the support frame is fixedly connected with a fixing column, the surface of the fixing column is rotatably connected with a movable rod, the surface of the movable rod is provided with a chamfered portion 1, and the surface of the movable rod is provided with a chamfered portion 2. The upper surface of the support frame is fixedly connected with a vertical rod, and a rotating rod is rotatably installed inside the vertical rod. The surface of the rotating rod is provided with an external thread, and the surface of the rotating rod is threadedly connected with a vibrating cap through the external thread. One side of the vertical rod is fixedly connected with a limiting rod, and the surface of the rotating rod is fixedly connected with a swinging piece, one side of the vertical rod is fixedly connected with a fixing plate 1, and the upper surface of the fixing plate 1 is fixedly connected with a spring 1, the upper surface of the support frame is fixedly connected with a fixing plate 2, and one side of the surface of the fixing plate 2 is fixedly connected with a spring 2.

[0007] Preferably, an extension plate is fixedly connected to one side of the support frame, and a locking bolt is installed on the internal thread of the extension plate.

[0008] Preferably, a pulley is movably installed inside the bottom of the support frame.

[0009] Preferably, a circular hole is opened on the surface of the vibrating cap, and the limiting rod is inserted into the vibrating cap through the circular hole.

[0010] Preferably, the inner wall of the vibrating cap is provided with an internal thread that matches the external thread on the surface of the rotating rod.

[0011] Preferably, the top end of the spring one is connected to the swinging member, and one end of the spring two is connected to the movable rod.

[0012] Preferably, the swing member is located close to the second chamfered portion, and the surface of the swing member has an inclined surface that matches the second chamfered portion.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The vibrating device for casting on the hydraulic press workbench is rotatably mounted on the surface of the fixed column through the setting of the movable rod, so it has flexibility. The driving wheel cooperates with the driven wheel to support the transmission belt. When the driving wheel is driven to rotate by the servo motor, the driving wheel can drive the transmission belt to rotate. The transmission belt is conducive to driving the support rod and the trapezoidal rod to move around the path of the driving wheel and the driven wheel. The outer surface shape of the trapezoidal rod is consistent with the chamfered portion 1, so that when the trapezoidal rod moves vertically, the movable rod can be pushed by the chamfered portion 1 to force it to move backward, so that the other end of the movable rod will be pushed forward, so that the position of the chamfered portion 2 will push the swing member to form an angle change. Through the setting of the swing member, its position is limited by the rotating rod, so when it is pushed by the movable rod, it can only make a circular motion with the rotating rod as the center, so that it can drive the rotating rod to rotate. The surface of the rotating rod is provided with an external thread and is threadedly connected with the vibrating cap, and the vibrating cap is limited by the limit rod and cannot rotate, so the rotating rotating rod can drive the vibrating cap to form a horizontal movement along the limit rod through the external thread, so that the vibrating cap moves horizontally.

[0015] 2. The vibrating device for casting on the hydraulic press workbench has a spring 1 so that when the swinging part makes a circular motion with the rotating rod as the center, it will press down the spring 1, so that the spring 1 can push up the swinging part in the opposite direction, and the same is true for the spring 2. After the trapezoidal rod is separated from the movable rod, the spring 1 cooperates with the spring 2 to push the swinging part and the movable rod to reset respectively. The resetting of the swinging part can help drive the rotating rod to reverse, so that the reversal of the rotating rod can drive the vibrating cap to move back and reset, and one left and right movement of the vibrating cap forms one vibration.

[0016] 3. The vibrating device for casting on the hydraulic press workbench can adopt servo motor models such as ECMA-C-20401ES, SD300P series, MRT-J5, s7-1200, etc. The servo motor can change the rotation direction by setting the servo parameters, thereby driving the transmission belt to rotate clockwise and counterclockwise, so that the trapezoidal rod can push the movable rod of the vertical array from the top or bottom to move, and then drive the vibrating cap of the vertical array to vibrate from top to bottom or from bottom to top in sequence, which is beneficial to form an upward or downward driving vibration of the module constituting the hydraulic press workbench, and is beneficial to the rapid discharge of air bubbles in the molten metal.
