Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example 1: referring to fig. 1, 3, 5 and 6, the molybdenum rod processing system with reciprocating continuous feeding of the present invention includes two electric furnaces 1 for concentrated material firing, a first electric furnace 101 and a second electric furnace 102 respectively, a processing machine head 2 for applying pressure on the outer wall surface of the molybdenum rod, and a material receiving device 3;
the first electric furnace 101 and the second electric furnace 102 are fixedly arranged on the moving platform 5 in parallel, and the moving mechanism 6 comprises a guide rail 601, a sliding block 602, a screw 603, a nut 604, a stepping motor 605 and a position sensor 606;
two guide rails 601 and a screw rod 603 are fixedly arranged below the movable platform 5; three sliding blocks 602 are respectively arranged on the two guide rails 601, and nuts 604 are arranged on the lead screws 603; the moving mechanism 6 is fixedly connected with the moving platform 5 through a sliding block 602 and a nut 604 and forms a support for the moving platform 5;
one end of the screw rod 603 is connected with a stepping motor 605, and when the stepping motor 605 runs forward or backward, the moving platform 5 can be driven to do reciprocating movement; two groups of position sensors 606, such as a travel switch, a photoelectric proximity switch and the like, are arranged on the moving path of the moving platform 5 and are used for setting two working positions of the moving platform 5, namely positions (a first position and a second position) of the first electric furnace 101 and the second electric furnace 102 which are in butt joint with a feed inlet of the processing machine head 2; when the movable platform 5 moves to a designated position, the position sensor 606 is triggered, the position sensor 606 sends out a control signal to stop the operation of the stepping motor 605, and the position of the movable platform 5 is fixed through the self-locking characteristic of the screw rod and the nut.
Limiting blocks 607 are respectively arranged at two sides of the moving mechanism 6 and are used for limiting the moving range of the moving platform 5. The system mainly relies on the position sensor 606 to determine the working position of the mobile platform 5, and the position sensor 606 is used for detecting the real-time position of the nut 604 in the example; the stopper 607 is normally inactive and only protects the mobile platform 5 when it moves beyond the range.
As shown in fig. 3, an example of a processing process for producing a molybdenum rod according to the present invention includes the steps of:
1. two batches of ten molybdenum rods with thick diameter (the diameter is 17.5 mm) are respectively fed into a first electric furnace 101 and a second electric furnace 102 in batches, concentrated material burning treatment and heating are carried out for about 30 minutes, and the temperature of the molybdenum rods is raised to 1500 ℃; the external dimensions of the electric furnace 1 in this example are 2000mm x 800mm; staggering the sintering completion time of the first electric furnace 101 and the second electric furnace 102 by staggering the feeding time;
2. when the sintering of the molybdenum rod in the first electric furnace 101 is completed, the stepping motor 605 is operated forward to drive the moving platform 5 to move downwards, so that the first electric furnace 101 is in butt joint with the feed inlet of the first processing machine head 201 (namely, the first position); the molybdenum rods in the first electric furnace 101 are all sent to the processing machine head 2 for processing through the material guiding wheel 4, the time for processing a batch of ten molybdenum rods by the processing machine head 2 is about 10 minutes, and the processed molybdenum rods are conveyed to the material receiving device 3 for collection through the material guiding wheel 4; then waiting for the sintering of the molybdenum rods in the second electric furnace 102 to be completed, and simultaneously putting the next ten thick-diameter molybdenum rods into the first electric furnace 101 for sintering;
3. the step motor 605 is operated reversely to drive the moving platform 5 to move upwards, so that the second electric furnace 102 is in butt joint with the feed inlet of the first processing machine head 201 (namely, the second position); at this time, the molybdenum rods in the second electric furnace 102 are also sintered, all the molybdenum rods in the second electric furnace 102 are sent into the processing machine head 2 through the material guiding wheel 4 for processing, the time for processing a batch of ten molybdenum rods by the processing machine head 2 is about 10 minutes, and then the processed molybdenum rods are conveyed to the material receiving device 3 through the material guiding wheel 4 for collection; then waiting for the molybdenum rods in the first electric furnace 101 to be sintered, and simultaneously putting the next ten thick-diameter molybdenum rods into the second electric furnace 102 for sintering;
and the continuous molybdenum rod processing process is realized by the reciprocating circulation.
At the moment, in the reciprocating movement process of the electric furnace, the distance of each movement stroke is less than 1 meter, and compared with the heating time of about 30 minutes, the electric furnace has enough time to complete the movement process; moreover, as the electric furnace 1 has relatively low requirements on installation precision and the requirement on the precision of the butt joint with the feeding hole of the processing machine head 2 is not high, the moving mechanism is enough to meet the application requirement; other known movement mechanisms may be employed; in addition, a manual fine adjustment operation function is arranged in the control system, so that the butt joint position of the electric furnace 1 and the processing machine head 2 can be calibrated in a small range.
Compared with the existing system, the processing machine head has the advantages that the processing pause time of the processing machine head is greatly shortened, and the processing efficiency is improved; the added equipment mainly comprises an electric furnace, a movable platform and a movable mechanism, and the cost is controllable.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
