Technical Field

The invention relates to the technical field of molybdenum rod production, in particular to a reciprocating type molybdenum rod processing system capable of realizing consistent feeding.

Background

At present, in order to obtain a molybdenum rod with a smaller diameter, a coarse molybdenum rod generally needs to be processed by a rotary forging machine, and the main body of the rotary forging machine is a processing machine head; namely: the diameter of the molybdenum rod is pressurized to be reduced by the pressure applied to the molybdenum rod by the machining head. The production process of the molybdenum rod is as follows (as shown in figure 2): feeding more molybdenum rods with the large diameter into an electric furnace together for centralized material burning treatment; then the molybdenum rod is sent into a processing head through a material guiding wheel, and the processing head applies pressure on the outer surface of the molybdenum rod to reduce the outer diameter of the molybdenum rod; after the processing is finished, the materials are conveyed to a material receiving device through a material guiding wheel to be collected.

Wherein, the structure of the processing head (as shown in fig. 3) comprises: the device comprises a shell, a weighing ring, a marble, a main shaft, a hammer head and a die; the working principle is as follows: when the main shaft rotates, the hammer head and the die are continuously opened and closed to apply pressure on the outer wall surface of the molybdenum rod so as to process the molybdenum rod; molybdenum rods with different outer diameters can be processed by changing the size of the die.

The problems of the existing production mode are as follows: the existing system adopts a series connection structure, and because the material burning time of the electric furnace is usually longer than the processing time of the processing machine head, the processing machine head is always in an idle state, the processing machine head is a processing mode of intermittent feeding, and the production efficiency of the molybdenum rod is seriously influenced.

Detailed Description

The technical solution 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 centralized material burning, a first electric furnace 101 and a second electric furnace 102, a processing 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 slide block 602, a lead 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 moving platform 5; three sliding blocks 602 are respectively arranged on the two guide rails 601, and nuts 604 are arranged on the screw rod 603; the moving mechanism 6 is fixedly connected with the moving platform 5 through a slide block 602 and a nut 604 and supports the moving platform 5;

one end of the screw 603 is connected with the stepping motor 605, and when the stepping motor 605 runs in the forward direction or the reverse direction, the moving platform 5 can be driven to move in a reciprocating manner; two groups of position sensors 606, such as a travel switch, a photoelectric proximity switch and the like, are arranged on a moving path of the moving platform 5 and are used for setting two working positions of the moving platform 5, namely the positions (a first position and a second position) where the first electric furnace 101 and the second electric furnace 102 are in butt joint with the feed inlets of the processing head 2; when the moving 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 moving platform 5 is fixed through the self-locking characteristic of the screw rod and the nut.

The two sides of the moving mechanism 6 are respectively provided with a limiting block 607 for limiting the moving range of the moving platform 5. The system mainly depends on a position sensor 606 to determine the working position of the mobile platform 5, in this example, the position sensor 606 is used for detecting the real-time position of the nut 604; the stop 607 is normally inoperative and is only protective when the mobile platform 5 is moved out of range.

As shown in fig. 3, the exemplary machining process for producing a molybdenum rod according to the present invention includes the following steps:

1. respectively feeding two batches of ten molybdenum rods with large diameters (the diameter is 17.5 mm) into a first electric furnace 101 and a second electric furnace 102 in batches, carrying out centralized material burning treatment, heating for about 30 minutes, and raising the temperature of the molybdenum rods to 1500 ℃; the outer dimensions of the electric furnace 1 in this example are 2000mm by 800 mm; the sintering completion times of the first electric furnace 101 and the second electric furnace 102 are staggered by staggering the feeding time;

2. when the molybdenum rod in the first electric furnace 101 is sintered, the stepping motor 605 operates in the forward direction to drive the moving platform 5 to move downwards, so that the first electric furnace 101 is in butt joint with the feeding hole of the first machining head 201 (i.e. a first position); the molybdenum rods in the first electric furnace 101 are all sent to the machining head 2 through the feeding wheel 4 to be machined, the time for machining a batch of ten molybdenum rods by the machining head 2 is about 10 minutes, and the machined molybdenum rods are conveyed to the material receiving device 3 through the feeding wheel 4 to be collected; then, after the molybdenum rods in the second electric furnace 102 are sintered, putting the next ten molybdenum rods with the large diameter into the first electric furnace 101 for sintering;

3. the stepping motor 605 runs in the reverse direction to drive the moving platform 5 to move upwards, so that the second electric furnace 102 is in butt joint with the feeding hole of the first processing head 201 (namely, at a second position); at this time, the molybdenum rods in the second electric furnace 102 are also sintered, the molybdenum rods in the second electric furnace 102 are all sent to the machining head 2 through the feeding wheel 4 for machining, the time for machining a batch of ten molybdenum rods by the machining head 2 is about 10 minutes, and the machined molybdenum rods are conveyed to the material receiving device 3 through the feeding wheel 4 for collection; then, after the molybdenum rods in the first electric furnace 101 are sintered, putting a next batch of ten molybdenum rods with the large diameter into the second electric furnace 102 for sintering;

and the continuous molybdenum rod processing process is realized by the repeated circulation.

At the moment, in the process of reciprocating movement of the electric furnace, the distance of each movement stroke is less than 1 meter, compared with the heating time of about 30 minutes, enough time is provided for completing the movement process; moreover, the requirement of the electric furnace 1 on the installation precision is relatively low, and the requirement on the precision of butt joint with the feed inlet of the processing machine head 2 is not high, so that the moving mechanism can meet the application requirement; other known movement mechanisms may also be employed; in addition, a manual fine adjustment operation function is arranged in the control system, and the butt joint position of the electric furnace 1 and the machining head 2 can be calibrated in a small range.

Compared with the existing system, 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.
