Description

Technical Field

[0001] The invention relates to the technical field of sealing ring processing machine tool structures, in particular to a sealing ring processing machine tool and a processing method thereof. Background Art

[0002] A sealing ring is a device used to prevent liquid or gas leakage. It is usually made of elastic material and has a sealing function. The choice of material is of great significance to its sealing performance and service life. Therefore, during the production process, the rubber material needs to be vulcanized to improve the service life and strength of the sealing ring.

[0003] Although the existing production machine tools can play the role of vulcanizing rubber materials during use, the existing machine tools are not equipped with a mechanism to increase the contact area between the co-vulcanizer and the rubber material. Therefore, during the operation process, the co-vulcanizer can only be brought into contact with the rubber material by smearing. However, in the actual operation process, the opening of the mold causes the outside air to be easily adsorbed between the vulcanizer and the rubber material, thereby reducing the production quality and practicality of the existing machine tools for sealing rings. For this reason, we propose a sealing ring processing machine tool. Summary of the invention

[0011] As a preferred technical solution of the present invention: the number of the hydraulic cylinders is two, and the two hydraulic cylinders are symmetrically distributed along the outer wall of the slide, and the outer wall of the slide is slidably connected to the outer wall of the moving frame.

[0012] As a preferred technical solution of the present invention: the diameter of the pressing ring is matched with the diameter of the die hole, and a rubber plate is placed on the top of the lower die.

[0013] As a preferred technical solution of the present invention: one end of the heating tube away from the rotating ring is fixedly assembled with the inner wall of the upper mold, the number of the heating tubes is several, and the several heating tubes are evenly distributed along the inner wall of the upper mold.

[0014] A processing method of a sealing ring processing machine tool comprises the following steps:

[0015] S1: First, after the user has installed the machine tool, the rubber material can be directly placed on the lower mold, and the rubber material can be contracted into the material guide tube along with the lower mold by using the contraction of the electric push rod output shaft, so that the slide on the movable frame can be moved due to the operation of the screw rod 2, thereby achieving the effect of automatically aligning the pressing ring and the mold hole, and then the heating tube can be brought close to the rubber material to heat it by extending the output shaft of the hydraulic cylinder, so as to ensure that the rubber material is heated and the stamping operation is completed;

[0016] S2: In order to ensure the discharge of air during the stamping process and avoid a large number of bubbles inside the product that affect the product quality, the user can use the motor to make the gear mesh with the gear ring, so that the rotating ring rotates, so that the feed pump can discharge the co-vulcanizing agent. At this time, the feed pipe will move with the feed pump to ensure that the co-vulcanizing agent delivered by the feed pipe can be more evenly sprinkled on the heated rubber material, thereby ensuring the uniformity of the rubber material vulcanization operation;

[0017] S3: During the process of spraying the co-vulcanizing agent, the rotation of the rotating ring can not only make the material guide pipe spray the co-vulcanizing agent more evenly, but also use the movement of the feed pump to push the moving seat to slide along the outer wall of the annular guide rail, so that the annular guide rail drives the sliding rod to move toward the end close to the annular guide rail, so that the piston slides along the inner wall of the gas collecting pipe and uses the gas-liquid separation membrane to isolate the liquid rubber material, and extract the excess air inside the upper mold and the mold hole to avoid the formation of a large number of bubbles in the product, thereby achieving the effect of automatically generating negative pressure to extract excess air, thereby improving the processing quality of the sealing ring of the machine tool and improving the practicality of the machine tool.

[0018] The present invention has the following beneficial effects:

[0019] 1. The sealing ring processing machine tool, through the set bed, motor, gear, gear ring, rotating ring, annular guide rail, feed pump, and guide pipe structure, enables the user to mesh the gear and the gear ring through the operation of the motor during the operation of the machine tool, so that when the feed pump transports the co-vulcanizing agent, the centrifugal force affects the spraying range of the guide pipe, thereby increasing the contact area between the co-vulcanizing agent and the rubber material, thereby improving the vulcanization effect of the rubber material in the machine tool.

[0020] 2. The sealing ring processing machine tool is equipped with an air collecting pipe, a return spring, a feed pump, a movable seat, an exhaust pipe, a one-way air outlet valve, a one-way air inlet valve, and a gas-liquid separation membrane structure. During operation, when the rotating ring allows the guide pipe to evenly throw out the co-vulcanizer due to the meshing of the gears and the gear ring, the feed pump can push the movable seat to slide along the outer wall of the annular guide rail, so that the piston slides along the inner wall of the air collecting pipe to generate negative pressure to extract the air between the rubber material and the mold, thereby avoiding the generation of a large number of bubbles inside the product and affecting the quality of the sealing ring, thereby improving the quality of the sealing ring produced by the machine tool and also improving the practicability of the machine tool.

[0032] In the above structure, by setting the bed 1, lower mold 2, electric push rod 3, feed pump 15, motor 16, gear 17, gear ring 18, and limit hole 19 structure, during the use of the machine tool, the user can operate the motor 16 to make the feed pump 15 use the rotatable characteristics of the rotating ring 22 and the guide pipe 20 when conveying the co-vulcanizing agent to make the guide pipe 20 spray the co-vulcanizing agent on the rubber material more evenly, thereby ensuring that the contact between the rubber material and the co-vulcanizing agent is more uniform, thereby improving the strength and service life of the sealing ring produced by the machine tool.

[0038] In the above structure, the gas-liquid separation membrane 32 is used to separate the gas and liquid through the gas collecting pipe 34 structure, thereby avoiding the situation where liquid rubber enters the gas collecting pipe 34 and solidifies to block the gas collecting pipe 34, and ensuring that excess air can enter the gas collecting pipe 34 for extraction, thereby ensuring the normal operation of the machine tool.

[0039] In a preferred embodiment, the angle between the end of the guide tube 20 and the pressing ring 21 is 15°, and a distance of 1 cm is provided between the rotating ring 22 and the pressing ring 21 .

[0040] In the above structure, by setting the included angle between the material guide pipe 20 and the pressing ring 21, the rotating ring 22 can rotate and drive the material guide pipe 20 to rotate, while the co-vulcanizing agent can be transported by the operation of the feeding pump 15, so that the end of the rotating material guide pipe 20 can also use centrifugal force to spray the co-vulcanizing agent more widely, thereby ensuring the spraying effect of the material guide pipe 20 on the co-vulcanizing agent, and improving the contact area between the co-vulcanizing agent and the rubber material and the vulcanization effect of the rubber material.

[0049] A processing method of a sealing ring processing machine tool comprises the following steps:

[0050] S1: First, after the user has installed the machine tool, the rubber material can be directly placed on the lower mold 2, and the rubber material can be contracted into the material guide tube 20 following the lower mold 2 by the contraction of the output shaft of the electric push rod 3, so that the slide 10 on the movable frame 7 can be moved due to the operation of the screw 2 9, thereby achieving the effect of automatically aligning the pressing ring 21 and the mold hole 14, and then the heating tube 35 can be close to the rubber material to heat it by extending the output shaft of the hydraulic cylinder 11, so as to ensure that the rubber material is heated and the stamping operation is completed;

[0051] S2: In order to ensure the discharge of air during the stamping process and avoid a large number of bubbles inside the product that affect the product quality, the user can use the motor 16 to make the gear 17 mesh with the gear ring 18, so that the rotating ring 22 rotates, so that the feed pump 15 can discharge the co-vulcanizing agent. At this time, the guide pipe 20 will move with the feed pump 15 to ensure that the co-vulcanizing agent delivered by the guide pipe 20 can be more evenly sprinkled on the heated rubber material, thereby ensuring the uniformity of the rubber material vulcanization operation;

[0052] S3: During the process of spraying the co-vulcanizing agent, the rotation of the rotating ring 22 can not only make the guide tube 20 spray the co-vulcanizing agent more evenly, but also can use the movement of the feed pump 15 to push the moving seat 26 to slide along the outer wall of the annular guide rail 23, so that the annular guide rail 23 drives the slide rod 30 to move toward the end close to the annular guide rail 23, so that the piston 29 slides along the inner wall of the gas collecting pipe 34 and uses the gas-liquid separation membrane 32 to isolate the liquid rubber material, and extract the excess air inside the upper mold 13 and the mold hole 14 to avoid the formation of a large number of bubbles in the product, thereby achieving the effect of automatically generating negative pressure to extract excess air, thereby improving the processing quality of the sealing ring of the machine tool and improving the practicality of the machine tool.
