[0011] The present invention provides a PTFE lining flanging device for an electromagnetic flowmeter. It has the following beneficial effects:

[0012] 1. The PTFE lining flanging equipment of the electromagnetic flowmeter is made of carbon steel square tubes, which can prevent the equipment from being deformed under stress during use and ensure the consistency of PTFE lining production. The small heating cone head assembly and the large heating cone head assembly reasonably control the temperature of the heating cone head assembly through thermal resistors and control cabinets, which can ensure that a reasonable temperature is maintained during the lining production process, effectively improving the quality and pass rate of the lining. Two different specifications of heating cone head assemblies can meet the production of linings of different specifications, making the equipment more efficient.

[0013] 2. The PTFE lining flanging equipment of the electromagnetic flowmeter is connected to the bottom plate and the fixed component, the forming component, the small heating cone head component, the large heating cone head component and the fixed block by slide rails to ensure the parallelism between the bottom plate and the equipment, to ensure that the PTFE lining will not be scrapped due to offset during the flanging process, and to ensure the verticality of each component to the bottom plate. In this way, the lining flanging can be completed and the lining warping can be prevented in the later stage. The forming component includes a water cooling system. The water output is controlled by the control cabinet according to different temperatures. After the lining flanging is completed, the lining flanging can be quickly shaped and cooled by squeezing the pressing cone block to prevent the lining from cracking in the later stage.

[0014] 3. The PTFE lining flanging equipment of the electromagnetic flowmeter is connected to the thrust screw through a bearing through a pressing cone block. During the rotation of the thrust screw, the pressing cone block shakes and the dust on the pressing cone block is cleaned, thereby ensuring the quality of the flanging material.

[0015] 4. The electromagnetic flowmeter PTFE lining flanging equipment cools the surface of the pressing cone block through the water outlet and the water cooling port. During the process of the pressing cone block leaving, the water sprayed from the water outlet is poured into the pressing cone block, which can fully cool the pressing cone block during the cooling process of the flanging material, ensuring the cooling of the flanging material.

[0016] 5. The PTFE lining flanging equipment of the electromagnetic flowmeter expands the mercury chamber after being heated, thereby squeezing the air chamber, thereby increasing the size of the air flow blown out of the air chamber. The air flow blown out of the air chamber carries the water flow injected after the last flanging press, thereby increasing the flushing of the pressing cone block and increasing the cleaning of dust and adhering flanging materials on the pressing cone block.

[0017] 6. The electromagnetic flowmeter PTFE lining flanging equipment, after the pressing cone block is squeezed by the flanging material, the pressing cone block squeezes the second elastic rod, so that the second elastic rod bounces up and pushes up the bouncing height of the rolling ball, so that the rolling ball knocks the pressing cone block, so that the pressing cone block can be in contact with the flanging material after being in contact, so that the flanging material is difficult to adhere to the pressing cone block.

[0034] In this embodiment, after the movement is adjusted to a desired position, the bolts on the fixing block 22 are fixed to fix the fixing block 22 .

[0035] Specifically, the interior of the thermal expansion and contraction mechanism 4 includes a mercury chamber 41, an air chamber 42, an extrusion rod 46 and a blocking block 47. A cavity is opened inside the pressing cone block 23. The air chamber 42 is fixedly connected to the inner wall of the cavity of the pressing cone block 23. The mercury chamber 41 is fixedly connected to the inner wall of the cavity of the pressing cone block 23 and located inside the air chamber 42. A hole is opened on the left side of the pressing cone block 23. A blocking block 47 is fixedly connected in the hole of the pressing cone block 23. An extrusion rod 46 is arranged at the axis of the air chamber 42. The extrusion rod 46 is in active contact with the blocking block 47. The right side of the extrusion rod 46 is fixedly connected to the thrust screw 21.

[0036] In this embodiment, the fixing assembly 12 and the forming assembly 13 are installed on a slide rail to adjust their positions.

[0037] Specifically, a circle of several first elastic rods 43 are fixedly connected to the inner wall of the pressing cone block 23 away from the right side of the air bin 42, and one end of the first elastic rod 43 is fixedly connected to the inner wall of the pressing cone block 23.

Three rolling balls 44 are arranged inside the pressing cone block 23, and the rolling balls 44 are in active contact with the first elastic rod 43 and the second elastic rod 45.

[0038] In this embodiment, the small heating cone head assembly 14 and the large heating cone head assembly 15 can be installed on a slide rail to move back and forth.

[0039] When in use, the steel material to be flanging is clamped in the fixing assembly 12, one end of the steel material is placed in the forming assembly 13, and the PTFE material of the flanging is installed. According to the different sizes of the flanging, a small heating cone head assembly 14 or a large heating cone head assembly 15 is used for heating. The small heating cone head assembly 14 and the large heating cone head assembly 15 can be installed on the slide rail for moving back and forth. The fixing assembly 12 and the forming assembly 13 are installed on the slide rail for adjusting the position. The fixing block 22 is installed on the slide rail. After moving and adjusting to the required position, the bolts on the fixing block 22 are fixed to fix the fixing block 22, and the thrust screw 21 is rotated to move the thrust screw 21 forward in the fixing block 22, so that the pressing cone block 23 squeezes the flanging material on the steel material. During the rotation of the thrust screw 21, the pressing cone block 23 is connected to the thrust screw 21 through the bearing, and will shake with the rotation of the thrust screw 21, so that the dust on it can be cleaned up, and the rolling ball 44 shakes back and forth in the pressing cone block 23, thereby continuously hitting the second elastic rod 45. One end of the second elastic rod 45 is fixed on the pressing cone block 23. When the rolling ball 44 hits the second elastic rod 45, the rolling ball 44 will bounce higher. One end of the first elastic rod 43 is fixed on the pressing cone block 23, and the other end of the first elastic rod 43 is fixed with a magnet, so the rolling ball 44 can be adsorbed. After the rolling ball 44 approaches the first elastic rod 43, it squeezes the first elastic rod 43 and will be elastically bounced away by the first elastic rod 43. Thereby, the rolling ball 44 is caused to swing in the pressing cone block 23 to clean the dust on the pressing cone block 23. When the pressing cone block 23 extrude the heated flanging material, the pressing cone block 23 is stuck in the chassis where the bearing is located, and the bearing extrude the extrusion rod 46. After the extrusion rod 46 extrude the blocking block 47, the blocking block 47 blocks the outlet of the air bin 42. The pressing cone block 23 contacts the heated flanging material, and the mercury in the mercury bin 41 is gradually heated. After the mercury is heated, it expands, thereby increasing its volume. After the mercury bin 41 is expanded, it squeezes the air inside the air bin 42. After the flanging material is extruded, the water inlet at the top of the molding component 13 is connected to the outside water pipe, so that water is added to the inside of the molding component 13, and the water flows out from the water cooling port 32 The flanging material is water-cooled to harden the flanging material, and the water flow squeezes the movable belt 31, so that the water flow flows out from the water outlet 33 to cool the bottom of the pressing cone block 23. During the water cooling process, the pressing cone block 23 gradually moves away from the flanging material. After the extrusion rod 46 moves away from the blocking block 47, the air flow in the air chamber 42 is compressed and then violently sprayed toward the outer wall of the pressing cone block 23, so that the pressing cone block 23 is separated from the flanging material faster, and the flanging material adhering to the pressing cone block 23 can be cleaned to a certain extent. Then, the water sprayed from the water outlet 33 will be poured into the air chamber 42 of the pressing cone block 23, and water cooling will be performed from the inside of the pressing cone block 23, thereby accelerating the cooling speed of the pressing cone block 23 and cooling the flanging material adhering to the pressing cone block 23.As a result, the flanging material adhered to the pressing cone block 23 falls off during the swinging process.
