[0032] The thin-walled stainless steel tube to be cold-drawn is hoisted to the other end of the container frame by an external conveying device, received by an external pushing device and continuously pushed close to the basic frame 1. When one end of the stainless steel tube contacts the cold-drawing die 9, the traction device provided at one end of the basic frame 1 works in coordination.

[0039] An adjusting cylinder embedded in the outer wall of the mold mounting frame 2 is provided on one end face of the supporting main arm 701, and a supporting auxiliary arm 702 is sleeved on the outer peripheral wall at the other end of the supporting main arm 701. The supporting auxiliary arm 702 is designed in a V-shaped structure, and a guide frame 705 close to the ring frame 801 is provided on the arm rod at one end of the top of the supporting auxiliary arm 702, and a plurality of rotating gear rods are provided on the frame body of the guide frame 705, and a driving motor 703 is provided on the arm rod at the other end of the supporting auxiliary arm 702.

[0040] A metal chain belt 704 is sleeved on the outer wall of the guide frame 705, and a rubber sleeve sleeved with the rotating gear stick and the output end of the driving motor 703 is arranged on the inner wall of the metal chain belt 704, and multiple sets of tooth grooves are arranged on the inner wall of the rubber sleeve. Multiple sets of magnetic isolation plates are arranged on the side of the guide frame 705 away from the ring frame 801, and a connecting disk 802 is embedded on the outer wall of the ring frame 801, and the connecting disk 802 is connected to the scraper 803. The inner wall of the scraper 803 has an arc-shaped structure, and an air jet 804 is arranged at the bottom of the outer wall of the scraper 803, and a liquid injection port 805 is arranged above the air jet 804. A liquid slip ring for connecting to the mold mounting frame 2 is arranged on the inner wall of the ring frame 801, and inclined plates 401 are symmetrically arranged on both sides of the top of the miscellaneous material conveying frame 4, one side of the miscellaneous material conveying frame 4 extends to the outside of the basic frame 1, and the other side of the miscellaneous material conveying frame 4 is located below the external magnetic impurity removal mechanism 7.

[0041] Embodiment 3: This embodiment is a cold drawing processing device suitable for thin-walled stainless steel pipes. A control panel close to the miscellaneous material conveying rack 4 is arranged on the outer wall of one side of the basic frame 1. A processor, a data acquisition module, a data analysis module, a subdivision comparison module and a signal execution module are arranged inside the control panel;

[0042] An ultrasonic sensor is provided on the arm supporting the auxiliary arm 702, and the ultrasonic sensor is used to collect the debris accumulation value generated by cold drawing between the outer cone ring 204 and the stainless steel tube. An industrial camera is provided on the outside of the limit cylinder 203, and the industrial camera is used to collect the surface damage state value of the stainless steel tube after cold drawing.

[0043] The data acquisition module collects the debris accumulation value and the damage state value during the stainless steel pipe processing through the ultrasonic sensor and the industrial camera, and marks the debris accumulation value and the damage state value as SX and SQ respectively, and sends the debris accumulation value SX and the damage state value SQ to the data analysis module through the processor;

[0044] The debris accumulation value SX represents the amount of debris generated by the cold drawing of the stainless steel pipe within the time threshold and accumulated in the outer area of ​​the outer cone ring 204. The larger the value of the debris accumulation value SX, the higher the risk of accumulation. The damage state value SQ represents whether there are scratches, defects and other damages on the surface of the stainless steel pipe after the cold drawing within the time threshold.

[0045] After receiving the chip accumulation value SX and the defect state value SQ, the data analysis module immediately analyzes the cold drawing risk of the processing device. The specific analysis process is as follows: the chip accumulation value SX and the defect state value SQ of the processing device within the time threshold are obtained, and the formula The cold drawing risk coefficient R is obtained, where a and b are the proportional coefficients of the debris accumulation value SX and the defect state value SQ, respectively, and a>b>0. The preset cold drawing risk coefficient YR stored and entered is retrieved from the processor for comparison and analysis with the cold drawing risk coefficient R.

[0046] If the cold drawing risk coefficient R ≥ the preset cold drawing risk coefficient YR, it is determined that there is an abnormal risk in the use of the processing device within the time threshold, and a cleaning signal is generated. The generated signal is sent to the subdivision comparison module and the signal execution module through the processor. After receiving the cleaning signal, the signal execution module;

[0047] The micromotor is immediately controlled to work. The micromotor drives the ring frame 801 to rotate along the annular guide rail through the transmission member. During the rotation of the ring frame 801, the scraper 803 is driven to rotate along the outer side of the outer cone ring 204. The scraper 803 pushes and scrapes the metal debris retained on the outer side of the outer cone ring 204, causing some metal debris with weaker correlation to break faster, and then causing some debris to fall into the miscellaneous material conveying rack 4.

[0048] After receiving the cleaning signal, the subdivision comparison module immediately obtains and marks the debris accumulation value SX and the damage state value SQ that generate the cleaning signal, and at the same time obtains the preset debris risk range and preset damage abnormal range recorded and stored from the processor and compares them with the debris accumulation value SX and the damage state value SQ:

[0049] If the debris accumulation value SX is greater than the maximum value of the preset debris risk range, and the damage state value SQ is less than the maximum value of the preset damage abnormal range, a maintenance inspection signal is generated, and the generated maintenance inspection signal is sent to the signal execution module. After receiving the maintenance inspection signal, the signal execution module;

[0050] The signal execution module immediately controls the adjusting cylinder, which drives the supporting main arm 701 to move laterally close to the outer cone ring 204. When the metal chain belt 704 is close to the outer side of the outer cone ring 204 and the outer side of the stainless steel tube, the driving motor 703 is started. The output end of the driving motor 703 is provided with a transmission roller which meshes with a set of teeth on the inner wall of the rubber kit, driving the rubber kit to drive the metal chain belt 704 to rotate, and the metal chain belt 704 meshes with the rotating tooth roller through another set of teeth on the inner wall of the rubber kit, limiting the metal chain belt 704 to rotate in a directional manner along the trajectory of the arrangement of multiple sets of rotating tooth rollers.

[0051] At the same time, the outer electromagnetic plate 706 is energized to generate magnetic force, and the outer electromagnetic plate 706 magnetically pulls the passing metal chain belt 704 and the metal debris close to the metal chain belt 704, causing the metal debris to be migrated and adsorbed on the surface of the metal chain belt 704, and the metal chain belt 704 rotates close to the inner electromagnetic plate. The magnetic force of the outer electromagnetic plate 706 is blocked by multiple groups of magnetic isolation plates, causing the metal chain belt 704 to rotate close to the side of the supporting main arm 701, and the metal chain belt 704 loses the magnetic force to pull the metal debris. Therefore, the metal debris falls into the miscellaneous material conveyor belt under the action of its own weight and the vibration of the rotating metal chain belt 704.

[0052] After waiting for the processing of this group of stainless steel pipes to be completed, the next group of stainless steel pipes are transported by external pushing equipment to wait for the processing interval. The micro motor drives the ring frame 801 to rotate in the opposite direction along the annular guide rail, prompting the scraper 803 to rotate in the opposite direction along the outer cone ring 204 and the inlet area of ​​the cold drawing die 9. At the same time, the external gas-liquid conveying equipment is connected along the bottom of the basic frame 1 through pipelines and valves, and is connected to the liquid slip ring, which is composed of multiple groups of air injection ports 804 and liquid injection ports 805;

[0053] First, high-pressure airflow is injected into the air jet 804, and the scraper 803 rotates slowly in the reverse direction to pneumatically flush and remove impurities from the outer cone ring 204 and the inlet area of ​​the cold drawing die 9. Then, the cleaning liquid and lubricant are sprayed on the surface in turn through the liquid injection port 805. After the cleaning liquid is sprayed, the air jet 804 sprays high-pressure airflow again to remove water stains attached to the inlet area of ​​the outer cone ring 204 and the cold drawing die 9. After this is completed, the lubricant is replaced and sprayed on the inlet of the outer cone ring 204 and the cold drawing die 9. A water collecting trough close to the miscellaneous material conveyor belt is provided below the bottom of the outer cone ring 204 to replace and flush the waste water generated by cleaning.

[0054] If the debris accumulation value SX is greater than the maximum value of the preset debris risk range, and the damage state value SQ is greater than the maximum value of the preset damage abnormal range, an alarm signal is generated, and the generated alarm signal is sent to the signal execution module. After receiving the alarm signal, the signal execution module immediately generates a text in the style of "production sequence K / mold damage / emergency plan activation" and sends it to the display screen of the main control room, where K represents the production line sequence, and K is a natural number greater than zero;

[0055] At the same time, the signal execution module controls the lifting cylinder 202 and the limiting cylinder 203 to start, and the limiting cylinder 203 drives the limiting low rod to disengage from the central groove 201, thereby releasing the restriction on the mold adjustment frame 6. The mold adjustment frame 6 is provided with two groups, the upper and lower groups, and the lifting cylinder 202 drives the lower group mold adjustment frame 6 to slide upward until the lower group mold adjustment frame 6 replaces the upper group mold adjustment frame 6, thereby exposing the upper group mold adjustment frame 6;

[0056] While waiting for the lower group of mold adjustment frame 6 to arrive at the specified position, the limit cylinder 203 drives the limit low rod to reinsert into the center groove 201, and the limit low rod enters along the limit slot 602 until the limit low rod contacts the side connecting frame 901, and then pushes the cold drawing mold 9 to adhere to the inner wall of the outer cone ring 204. It should be noted that a spring damper is provided on the inner wall of one end of the limit bracket 604 close to the outer cone ring 204, which is used to push the cold drawing mold 9 to move close to one end of the limit slot 602 after contacting the limit.

[0057] If the cold drawing risk factor R is less than the preset cold drawing risk factor YR, no signal is generated.

[0058] Combining Example 1 and Example 2, it can be seen that not only can the automated cold drawing of thin-walled stainless steel pipes be achieved, but the feed bracket 5 can also be adjusted according to the size of the steel pipe to ensure uniform processing speed and quality, and can also monitor debris accumulation and surface damage in real time, automatically trigger cleaning or maintenance signals, and take corresponding measures according to different situations to ensure the continuity and stability of production and take corresponding measures according to different situations.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
