The process boss 25 for process flow transfer is designed at the upper end of the aircraft rotor hub blank, so that the purpose of grabbing a plurality of aircraft rotor hub blanks by one robot can be realized.
Fig. 2 shows in cross section a blank to be die-cut press-calibrated by means of a compound die to which the utility model is to be applied.
As shown in fig. 3, 4 and 5, an example of a compound die of 8 pieces is shown, 8 pieces of aircraft rotor hub blanks can be arranged between the lower large plate 20 and the upper large plate 1 in parallel between the lower die 24 and the upper discharge plate 9 respectively, and punching, pressing and correcting forging is carried out by adopting a punch i 3, a punch ii 5, a punch iii 6, a cutting edge i 8, a cutting edge ii 10 and the like respectively, so that the punching, pressing and correcting work can be finished by 8 punches simultaneously with 8 cutting edges at one time, and the production efficiency is improved.
The guide post 22 and the guide sleeve 23 which are slidably matched with each other are respectively connected to the lower large plate 20 and the upper large plate 1 through bolts. The upper large plate 1 is connected with the fixed base plate 7 through a fixed bolt I2, and the cutting edge I8 and the cutting edge II 10 are connected under the upper large plate 1 and the fixed base plate 7 through the fixed bolt I2. The upper stripper plate 9 is connected under the upper large plate 1 and the fixed base plate 7 through a fixed bolt I2 and a stripper spring 4, the stripper spring 4 passes through the fixed bolt I2 and is arranged between the lower part of the fixed base plate 7 and the upper stripper plate 9, and the fixed bolt I2 is arranged in a bolt hole penetrating through the upper large plate 1. The pin 11 is arranged in the cutting edge I8, the cutting edge II 10, the upper large plate 1 and the fixed base plate 7 to play a role in positioning. The punch I3, the punch II 5 and the punch III 6 are fixed in the upper large plate 1 and the fixed base plate 7.
A lower die supporting column 16 is arranged between the lower die 24 and the lower large plate 20, wherein the lower die 24 is connected with the lower die supporting column 16 through a fixing bolt II 15, the lower die supporting column 16 is connected onto the lower large plate 20 through a fixing bolt II 15, the lower flash discharging tray 13 is connected onto a connecting plate I17 through a fixing bolt II 15, and the connecting plate I17 is in threaded connection with a lower connecting supporting plate 18. The lower connection pallet 18 is connected with a lifter connection plate 19 (one on each of left and right sides) which is arranged in a vertically movable manner on the lower large plate 20. 4 guide posts 22 are arranged on the lower large plate 20 through bolts, and 4 guide sleeves 23 are arranged below the upper large plate 1 through bolts.
The upper and lower profiles of the upper and lower discharge plates 9 and 24 are required to be subjected to profiling numerical control processing with the forging contact surface of the aircraft rotor hub 12, compaction is guaranteed, the cutting edges I8 and 10 and the lower flash discharge tray 13 are required to be subjected to profiling numerical control processing with the forging contact surface of the aircraft rotor hub 12, the quality of punched parts can be guaranteed along with the shape of products, and deformation of the forging of the aircraft rotor hub 12 in the punching and press correction processes is prevented.
Because of the relatively large size and profile of the aircraft rotor hub 12, this creates a difficult, i.e., non-grabbing, problem for one robot to grab multiple aircraft rotor hubs. In order to grasp a plurality of aircraft rotor hubs in an effective clamping jaw space, a robot clamping jaw grasping process boss 25 for process flow transfer is specially designed on an aircraft rotor hub blank as a grasping process jaw so as to achieve the aim of grasping a plurality of aircraft rotor hub blanks by one robot.
In this way, multiple groups of upper stripper plates 9 and lower dies 24 are arranged in parallel between the lower large plate 20 and the upper large plate 1, and 4 or 8 trimming and punching combined works can be completed simultaneously in a one-die-multiple-piece mode. One die 8 pieces are used for simultaneously cutting off the forging flash and punching the shaft hole for one time to complete the press correction and the combination, so that the time and the labor can be saved, the equipment can be saved, the cost can be reduced, and the efficiency can be improved. Meanwhile, the upper surface of the upper stripper plate 9 and the lower surface of the lower die 24 can be subjected to micro-correction and micro-compression according to the requirements. The lower profile of the upper stripper plate 9 is formed with a profile corresponding to the process boss 25.
When the whole upper die of the upper large plate 1, the upper discharging plate 9 and the cutting edge II 10 is in an upper state, the robot clamping jaw can grasp 8 aircraft rotor hub blanks at the positioning position by grabbing 8 aircraft rotor hub blanks, and the robot can grasp the process boss 25.
The robot clamping jaw leaves after putting 8 light alloy aircraft rotor hub blanks on lower mould 24, and then the press slider drives big board 1 to descend and drives drift I3, drift II 5, drift III 6, go up stripper 9 and blade I8, blade II 10 and descend, go up stripper 9 compaction press correction formula light alloy aircraft rotor hub blanks, and big board 1 continues to descend and drives drift I3, drift II 5, drift III 6 continues to descend, and discharge spring 4 is compressed simultaneously.
Thus, the punch I3, the punch II 5 and the punch III 6 start to punch, the cutting edge I8 and the cutting edge II 10 start to cut off the flash 14 of the rotor hub blank of the light alloy aircraft until the stop of the work is completed until the limit is completed, and the scraps 21 punched by the punch I3, the punch II 5 and the punch III 6 fall from the lower die 24.
Meanwhile, the upper surface of the upper discharging plate 9 and the lower surface of the lower die 24 can be subjected to micro-correction and micro-compression on the upper surface of the rotor hub blank, and the effect of one die with multiple functions can be achieved.
After the work is finished, the press slide block of the equipment press drives the upper large plate 1 to move upwards, drives the punch I3, the punch II 5, the punch III 6 and the upper stripper 9 to move upwards, and the punched light alloy aircraft rotor hub blank is ejected out of the punch I3, the punch II 5 and the punch III 6 under the compression force of the unloading spring 4 connected with the upper stripper 9.
The robot hand clamping jaw takes away the light alloy aircraft rotor hub blank after the operation and leaves, and simultaneously the cut flash 14 is jacked up under the jacking action of a lower ejector of the press, namely, an ejector rod (not shown) of the press jacks up the ejector connecting plate 19, and under the driving of the ejector connecting plate 19, the connecting support plate 18, the connecting plate I17 connected with the connecting plate and the lower flash discharging tray 13 jack up the flash 14, so that the flash 14 is ejected out of the lower flash discharging tray 13 from the lower die 24, and the work is completed. The flash 14 is removed by a separate gripping device.
The next set of work-piece work-cycles may then be cycled to accomplish the task.
The description has been made above with reference to the arrangement of fig. 3 in which the punch i 3 and the punch iii 6 constitute a group of 6 and 8 in total, serving as an edge punch for punching the edge hole. The punches ii 5 constitute a group of 1 and 8 in total, and serve as a center punch for punching a center hole. The cutting edges I8 and II 10 adopt the same structure, and any one of the cutting edges used for cutting flash is arranged between every two groups.
