Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of the present invention.

[0031] Embodiment 1: Please refer to Figure 1 - Figure 9 As shown, this embodiment is a cold drawing processing device suitable for thin-walled stainless steel pipes, including a basic frame 1. A discharge connection frame 3 is provided on the outer wall of one end of the basic frame 1. A mold mounting frame 2 is embedded in the middle of one end of the basic frame 1. A mold adjustment frame 6 is sleeved inside the mold mounting frame 2. A cold drawing mold 9 is arranged inside the mold adjustment frame 6. An external magnetic impurity removal mechanism 7 and an internal rotating impurity removal mechanism 8 are arranged on the end face of the mold mounting frame 2;

[0032] The thin-walled stainless steel pipes to be cold drawn are lifted by an external conveying device to the other end of the container frame and received by an external pushing device, which continuously pushes them close to the basic frame 1. When one end of the stainless steel pipe contacts the cold drawing mold 9, a traction device arranged at one end of the basic frame 1 works in cooperation. The traction device clamps the inner wall of the stainless steel pipe through a fixture and guides and drags it. In combination with the linkage use of the pushing device, the surface of the stainless steel pipe is processed by the cold drawing mold 9.

[0033] At the top of one end of the basic frame 1, there is an installation groove 101 that runs through and is sleeved with the mold installation frame 2. On the inner wall of the other end of the basic frame 1, there is a recessed lifting cylinder 102. On the end face of the feeding bracket 5, there is a connecting beam body 501 connected to the lifting cylinder 102. At the top of the feeding bracket 5, there is an arc-shaped frame, and a number of ball bearings are arranged on the inner wall of the arc-shaped frame;

[0034] During the cold drawing process of the stainless steel pipe, when the stainless steel pipe is pushed close to the basic frame 1 by external equipment, the lifting cylinder 102 drives the feeding bracket 5 to adjust its height according to the conveying height and pipe outer diameter of the stainless steel pipe to be processed, so that the feeding bracket 5 moves synchronously with the lifting cylinder 102 through the connecting beam body 501, causing the feeding bracket 5 to contact the outer wall of the stainless steel pipe to be processed, and is used to assist it to pass through the cold drawing die 9 at a uniform speed.

[0035] During the surface cold drawing process of the stainless steel pipe by the cold drawing die 9, the excess wall thickness and convex areas on the surface of the stainless steel pipe are scraped and cleaned by the cold drawing die 9, and the scraped impurities remain between the cold drawing die 9 and the outer conical ring 204. Some of the broken impurities fall onto the miscellaneous material conveying frame 4 under the subsequent extrusion of impurities and are transported outside the basic frame 1 by it;

[0036] At the center of the top of the mold installation frame 2, there is a central groove 201 that runs through and is sleeved with the mold adjustment frame 6. On both sides of the central groove 201, there are symmetrically embedded lifting cylinders 202. On both sides of one end of the mold installation frame 2, there are limit cylinders 203, and on the end face of the limit cylinder 203, there is a limit rod that penetrates into the inside of the central groove 201. In the middle of the end face of the mold installation frame 2, there is a circular opening. On the outer wall of the circular opening close to the inner rotating impurity removal mechanism 8, there is an outer conical ring 204, and an annular guide rail and a micro-motor are embedded on the outer circumference of the outer conical ring 204.

[0037] On the top of the mold adjustment frame 6, there is a cover 601. On both sides of one end of the mold adjustment frame 6, there are symmetrically opened limit slots 602. On both sides inside the mold adjustment frame 6, there are symmetrically arranged limit beam bodies 603, and on the bottom side of the limit beam body 603, there is a limit bracket 604. On both sides of the cold drawing die 9, there are side connection frames 901 that are embedded inside the limit slots 602.

[0038] Embodiment 2: This embodiment is a cold drawing processing device suitable for thin-walled stainless steel pipes, including an external magnetic impurity removal mechanism 7 including a support main arm 701 and a metal chain belt 704. Inside the metal chain belt 704, there is an external electromagnetic plate 706. The inner rotating impurity removal mechanism 8 includes a ring frame 801 and a scraper 803. In the middle of one side of the basic frame 1, there is a miscellaneous material conveying frame 4 that runs through, and at the other end of the basic frame 1, there is a feeding bracket 5.

[0039] One end face of the supporting main arm 701 is provided with an adjusting air cylinder embedded in the outer wall of the mold mounting frame 2. The outer peripheral wall of the other end of the supporting main arm 701 is sleeved with a supporting sub-arm 702. The supporting sub-arm 702 is designed in a V-shaped structure. One end of the top arm of the supporting sub-arm 702 is provided with a guide frame 705 close to the ring frame 801. A number of rotating tooth sticks are arranged on the frame of the guide frame 705. A driving motor 703 is arranged on the other end arm of the supporting sub-arm 702.

[0040] A metal chain belt 704 is sleeved on the outer wall of the guide frame 705. Rubber sleeves sleeved on the output ends of the rotating tooth sticks and the driving motor 703 are arranged on the inner wall of the metal chain belt 704. Multiple groups of tooth grooves are arranged on the inner wall of the rubber sleeves. Multiple groups of magnetic isolation plates are arranged on the side of the guide frame 705 away from the ring frame 801. A connecting disk 802 is embedded on the outer wall of the ring frame 801. The connecting disk 802 is connected with a scraping plate 803. The inner wall of the scraping plate 803 is in an arc structure. An air jet port 804 is arranged at the bottom of the outer wall of the scraping plate 803. A liquid injection port 805 is arranged above the air jet port 804. A liquid slip ring for connecting the mold mounting frame 2 is arranged on the inner wall of the ring frame 801. 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 applicable to thin-walled stainless steel pipes. A control panel close to the miscellaneous material conveying frame 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 arranged on the arm of the supporting sub-arm 702. The ultrasonic sensor is used to collect the value of the debris accumulation amount generated during the cold drawing between the outer conical ring 204 and the stainless steel pipe. An industrial camera is arranged outside the limit air cylinder 203. The industrial camera is used to collect the surface damage state value of the stainless steel pipe after cold drawing.

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

[0044] Among them, the debris accumulation value SX represents the amount of debris accumulated in the outer area of the outer conical ring 204 generated by the cold drawing of the stainless steel pipe within the time threshold. 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 cold drawing within the time threshold.

[0045] After receiving the chip accumulation value SX and the damage status value SQ, the data analysis module immediately analyzes the cold drawing risk of the processing device. The specific analysis process is as follows: Obtain the chip accumulation value SX and the damage status value SQ of the processing device within the time threshold. Through the formula Obtain the cold drawing risk coefficient R. a and b are the proportionality coefficients of the chip accumulation value SX and the damage status value SQ respectively, where a > b > 0. And retrieve the preset cold drawing risk coefficient YR stored and entered in 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 sub - comparison module and the signal execution module through the processor. After receiving the cleaning signal, the signal execution module;

[0047] Immediately controls the micro - motor to work. The micro - motor drives the ring frame 801 to rotate along the annular guide rail through the transmission part. During the rotation of the ring frame 801, the scraper 803 is driven to rotate along the outside of the outer conical ring 204. The scraper 803 pushes and scrapes the metal chips remaining on the outside of the outer conical ring 204, causing some metal chips with relatively weak correlation to accelerate fracture, and then causing some chips to fall into the miscellaneous material conveying rack 4.

[0048] After receiving the cleaning signal, the sub - comparison module immediately separately obtains and marks the chip accumulation value SX and the damage status value SQ that generate the cleaning signal. At the same time, it obtains the preset chip risk range and the preset damage abnormal range stored and entered in the processor for comparison with the chip accumulation value SX and the damage status value SQ:

[0049] If the chip accumulation value SX is greater than the maximum value of the preset chip risk range, and the damage status value SQ is less than the maximum value of the preset damage abnormal range, a maintenance inspection signal is generated. 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 adjustment cylinder. The adjustment cylinder drives the support main arm 701 to move horizontally closer to the outer conical ring 204. When waiting for the metal chain belt 704 to approach the area outside the outer conical ring 204 and the outside of the stainless steel pipe, the drive motor 703 starts. A transmission roller is arranged at the output end of the drive motor 703 and meshes with a set of tooth grooves 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 rollers through another set of tooth grooves on the inner wall of the rubber kit, restricting the metal chain belt 704 to rotate in a fixed direction along the trajectory arranged by multiple 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] When waiting for the next set of die adjustment frames 6 to reach the designated position, the limit cylinder 203 drives the limit lower rod to re-insert into the central groove 201, and the limit lower rod enters along the limit slot 602 until the limit lower rod contacts the side connection frame 901, thereby pushing the cold drawing die 9 to adhere to the inner wall of the outer conical 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 conical ring 204, which is used to push the cold drawing die 9 to move closer to one end of the limit slot 602 after contacting the limit.

[0057] If the cold drawing risk coefficient R < the preset cold drawing risk coefficient YR, then no signal is generated.

[0058] Combining Embodiment 1 and Embodiment 2, it can be seen that it can not only realize the automatic cold drawing processing of thin-walled stainless steel pipes, but also adjust the feeding bracket 5 according to the size of the steel pipe to ensure uniform processing and quality, and can also monitor the accumulation of debris and surface defects in real time, automatically trigger the cleaning or maintenance inspection signal, 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 present invention to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and changes can be made.
