In the initial state, the working end of the rotary cutting mechanism 8 is away from the mold 2 and ready for loading. The worker controls the working end of the covering mechanism 3 to move away from the mold 2 through the controller to remove the sealing effect on the top end of the mold 2. The working personnel also send signals to the opposite displacement driving mechanism 4 through the controller, and the opposite displacement driving mechanism 4 drives the pair of sliding seats 5 to drive the material conveying barrel 6 and the material pushing mechanism 7 which are fixed on the sliding seats 5 to move in the direction away from the die 2 together after receiving the signals, so that a space is reserved for the working personnel to feed materials. The operator places the tube blank in the mould 2 with only vertical freedom. Then the working personnel sends a signal to the covering mechanism 3 through the controller, and the covering mechanism 3 drives the working end to do horizontal movement to cover the top end of the mould 2 after receiving the signal, so as to limit the last degree of freedom of the tube blank and ensure that the tube blank is completely fixed in the mould 2.

Under the driving action of the bidirectional screw rod 4c and the guiding action of the guide rod 4d, the pair of sliding blocks 4e drive the lantern rings 4f to synchronously approach or separate from each other, so that the pair of sliding seats 5 are driven to symmetrically approach or separate from each other.
As shown in fig. 8, the opposing displacement drive mechanism 4 further includes a stopper plate 4 g; the limiting plate 4g is vertically arranged at the central position of the second driving support 4a, and the limiting plate 4g is rotatably connected with the bidirectional screw rod 4 c.
The central position of the bidirectional screw rod 4c is fixed by additionally arranging the limit plate 4g on the second driving support 4a, so that the bidirectional screw rod 4c is prevented from vibrating due to overlong length. The structural stability is further improved.
As shown in fig. 9, the material conveying barrel 6 is provided with a material inlet 6a, a material pushing port 6b, a material outlet 6c and a guide plate 6 d; the feeding port 6a is arranged at two sides of the material conveying cylinder 6 symmetrically with a bidirectional screw rod 4c at the top end of the horizontally arranged material conveying cylinder 6, the inner side of the die 2 is attached to the outer side of the material outlet 6c in a non-working state, the guide plate 6d is arranged between the pair of material outlets 6c, and the material pushing port 6b is arranged at one end, far away from the guide plate 6d, of the material conveying cylinder 6 and is in clearance fit with the working end of the material pushing mechanism 7.
The staff injects the solid particle into the material transferring cylinder 6 through the material inlet 6 a. Under the non-working state, the inner side of the die 2 blocks the discharge hole 6c so that solid particles are completely remained in the conveying barrel 6, and the solid particles cannot overflow to cause waste. When the pair of working ends of the opposite displacement drive mechanism 4 are brought close to each other, the pair of transfer cylinders 6 are also brought close to each other, and the end where the discharge port 6c is located is inserted into the tube blank. When the working end of the pushing mechanism 7 extends from the pushing port 6b to the interior of the material conveying cylinder 6, the solid particles can be pushed to expand outwards from the discharge port 6c, and the tube blank is extruded to form a lute bag. The guide plate 6d has a herringbone structure, and plays a role in guiding the movement of solid particles.
As shown in fig. 10, the pushing mechanism 7 includes a third driving bracket 7a, a second linear driver 7b and a pushing piston 7 c; the third driving support 7a is fixedly installed on the workbench 1 and located on one side of the die 2, the second linear driver 7b is fixedly installed on the third driving support 7a, the output end of the second linear driver faces the direction of the die 2, the pushing piston 7c is fixedly connected with the output end of the second linear driver 7b and is in sliding connection with the inner wall of the die 2, and the pushing piston 7c is in clearance fit with the inner wall of a tube blank arranged in the die 2 in a working state.
The second linear actuator 7b is a hydraulic cylinder. The third drive carriage 7a provides support for the second linear actuator 7 b. The controller sends a signal to the second linear driver 7b, and the second linear driver 7b drives the pushing piston 7c to move in the material conveying cylinder 6 after receiving the signal, so that the solid particles in the material conveying cylinder 6 are pushed into the tube blank.
As shown in fig. 4, the rotary cutting mechanism 8 includes a third linear driver 8a and a cutter 8 b; the third linear driver 8a is arranged on one side of the workbench 1, the moving direction of the third linear driver faces the direction of the workbench 1, and the cutting machine 8b is fixedly arranged on the working end of the third linear driver 8 a.
The cutting machine 8b is a common cutting machine with a rotary cutting function, and is not described herein. The controller controls the cutter 8b to move close to or away from the worktable 1 through the third linear driver 8 a. The cutter 8b is remote from the table 1 so that it is possible for the worker to easily feed and discharge the mold 2.
As shown in fig. 5, the ejection mechanism 9 includes a fourth linear actuator 9a and an ejector block 9 b; fourth linear actuator 9a fixed mounting is in the vertical upwards setting of 1 bottom of workstation and working end, and kicking block 9b fixed mounting just with mould 2 bottom clearance fit on fourth linear actuator 9a output, and fourth linear actuator 9a is connected with the controller electricity.
The fourth linear actuator 9a is an electric push rod. The controller sends a signal to the fourth linear driver 9a, and the fourth linear driver 9a drives the ejector block 9b to vertically move upwards after receiving the signal, so that the rotary-cut workpiece is ejected out of the die 2, and the workpiece is convenient for a worker to take the workpiece. The top surface of the top block 9b is flush with the bottom surface of the groove 2a of the die 2 and forms a complete plane when the ejection mechanism 9 is not in operation.
The working principle of the invention is as follows:
the device realizes the functions of the invention through the following steps, thereby solving the technical problems provided by the invention:
firstly, a worker controls the working end of the covering mechanism 3 to move away from the mold 2 through the controller so as to remove the sealing effect on the top end of the mold 2. The working personnel also send signals to the opposite displacement driving mechanism 4 through the controller, and the opposite displacement driving mechanism 4 drives the pair of sliding seats 5 to drive the material conveying barrel 6 and the material pushing mechanism 7 which are fixed on the sliding seats 5 to move away from the direction of the die 2 together after receiving the signals, so that a space is reserved for the working personnel to carry out feeding;
secondly, putting the tube blank into a die 2 by a worker to enable the tube blank to have only vertical freedom degree;
thirdly, the worker sends a signal to the covering mechanism 3 through the controller, and the covering mechanism 3 drives the working end to horizontally move to cover the top end of the mold 2 after receiving the signal, so as to limit the last degree of freedom of the tube blank and completely fix the tube blank in the mold 2;
and step four, the controller sends a signal to the opposite displacement driving mechanism 4, and the opposite displacement driving mechanism 4 drives a pair of sliding seats 5 to carry the material conveying cylinder 6 filled with the solid particles and the material pushing mechanism 7 to be mutually centralized after receiving the signal. The front ends of a pair of charging barrels 6 are synchronously inserted into the tube blank and finally abut against each other at the symmetrical section of the tube blank;
and fifthly, the worker sends a signal to the pushing mechanism 7 through the controller, and after receiving the signal, the pushing mechanism 7 makes a linear motion at a working end in the material conveying cylinder 6 to push the solid particles in the material conveying cylinder 6 to the output end of the material conveying cylinder 6 so that the solid particles start to expand outwards from the output end of the material conveying cylinder 6 to extrude the tube blank. The center of the tube blank is positioned at an arc-shaped sunken part for forming an axle housing lute on the die 2, and the center of the tube blank is stretched to two sides to be in the shape of the lute;
and step six, the worker sends a signal to the covering mechanism 3, the opposite displacement driving mechanism 4 and the sliding seat 5 through the controller, and the working end of the covering mechanism 3 moves backwards after receiving the signal, so that the upper end of the mold 2 is opened. The opposite displacement driving mechanism 4 and the sliding seat 5 move backwards and reset after receiving signals;
and seventhly, the working personnel send signals to the rotary cutting mechanism 8 through the controller, and after receiving the signals, the rotary cutting mechanism 8 firstly moves in the direction close to the working table 1 to enable the working end to move above the workpiece. Then the rotary cutting mechanism 8 carries out rotary cutting operation on the upper end of the workpiece to enable the upper end of the workpiece to form a speed reducer shell mounting hole;
step eight, resetting the rotary cutting mechanism 8 after cutting, sending a signal to the ejection mechanism 9 by the controller, and ejecting the workpiece in the die 2 upwards by the upward working end of the ejection mechanism 9 after receiving the signal so as to facilitate the blanking of workers;
and step nine, punching the workpiece by the worker in the last step to enable the other surface of the workpiece opposite to the mounting hole of the speed reducer shell to form a bridge package. After the processing is completed, the worker replenishes the solid particles into the material transfer cylinder 6 to perform the next operation, and recycles the solid particles left in the workpiece.
