Description

Clamping mechanism for molding machine feeding

This creation is related to the design of a clamping machine, especially a clamping mechanism for the feeding of the molding machine.

Press, in the processing and manufacturing of blanks from cutting to forming into forged parts, they all need to go through different stamping processes. Therefore, most of the smaller size forming machines will pass the smaller blanks first. The discharge of a vibrating aligning device, and then using a guide rail to output a whole row, to directly feed the material into the processing machine for the next process of forming processing operations, to complete a consistent continuous process; if you want to make a formed satin If the manufactured parts are of larger size, the blanks cannot be aligned by the vibrating alignment device. At this time, it is necessary to install a large-size guide ramp on the feed of the molding machine, and manually The working method arranges the blanks to be processed on the guide inclined plate one by one. Of course, in order to enable the larger size blanks to be effectively and stably clamped to complete the processing procedure, there will be a meeting on the feeding of the molding machine. There is a fixture set in an X-clamped state, and then the fixture directly cooperates with the clamping to complete the processing and forming operation.

However, although the inconvenience of the initial feeding is solved by the addition of the guide swash plate, it is found after actual use that the guide swash plate is too large and takes up space, which causes considerable inconvenience in use, and it is more inconvenient to use each time. It is necessary to manually feed the blanks one by one on the guide ramp. This is not only tedious and laborious, but if the operator does not notice and forgets to make up for a while, this will cause the forming machine to run idly. The operation of the molding machine caused damage to the mold of the molding machine. Relatively, the operator must stand on one side at any time to be on standby so that the blank can be filled in real time. At the same time, since the fixture is only clamped through X The open and close clamping method is used to clamp and move the blank, and the force point of clamping is located at the front. Once used for a period of time, it will cause the screw joint of the cross pivot end of the clamp to easily become loose due to vibration. The phenomenon of detachment easily leads to displacement errors of the fixture when clamping and moving the blank, and it cannot be accurate and stable when clamping and placing, which leads to an increase in the rate of processing and molding defects, and also affects the overall processing and molding operations; in view of this, this case The creator has made improvements and researches specifically to address the aforementioned issues in order to file a patent application for this case.

Therefore, the object of the present invention is to provide a clamping mechanism for the feeding of the molding machine, which can drive the clamping device to produce rotation and clamping cooperation with the certainty and smoothness under the drive generated by the driving device.

At this time, the two clamping paws A1 and A2 can reliably receive the blank material derived from the discharge port.

Continuing the foregoing, when the two clamping jaws A1 and A2 actually clamp the blank, the linkage seat 325 will immediately apply a pulling action to the linkage rod 324 to pull the linkage rod 324 inward, so that the driving arm 333 is actuated on the linkage rod 324 The upper and lower synchronizing racks B2 and B3 are linked again to maintain the same displacement during operation through the setting of the meshing synchronizing gear B1, so that the clamping jaw A1 is expanded from the clamping jaw A2. The state is converted to a closed state for clamping the blank, and then the clamping group 332 is driven by the transmission rod 321 on the swing arm seat 331, and the rotating arm 327 drives the turntable 328 to rotate on the fixed plate 326 After rotating from the discharge port to the feed port so that the two clamping jaws A1 and A2 correspond to the feed port, the driving arm 333 will be pushed out again by the linkage rod 324 to actuate the traction The two clamping jaws A1 and A2 will be released from the original state where the blank is clamped, and then form a loose state that is simultaneously expanded. At this time, the blank will be loosened in the two clamping jaws A1, A2. It enters into the feed inlet and is forged by the forming machine at the same time it is placed, so that the blanks can complete the forging forming processing operations, so that the forming machine completes the forging operations of the blanks; therefore, through the pendulum The arm base 331 and the rotating arm 327 are directly linked by the transmission rod 321 to drive the clamping group 333 to rotate and swing at the position between the discharge port and the feed port, and then be appropriately applied through the linkage rod 324 The push-pull traction action of the driving arm 333 enables the clamping group 332 to open and close a blank material at the discharge port and the material inlet, and it can not only stabilize the blank material of different specifications and sizes. Clamping, in order to achieve the efficiency of reliable feeding processing, can also avoid unnecessary replacement and increase of machinery and tools, and can effectively achieve the smoothness of molding processing and other effects.
