Description

Technical Field

[0001] The invention relates to the technical field of rubber hoses, in particular to a secondary vulcanization system for rubber hoses. Background Art

[0002] At present, the domestic rubber hose vulcanization method is direct steam vulcanization. When the rubber brake hose is vulcanized with a peroxide vulcanization system, this vulcanization method will cause an oxidation reaction between the rubber on the brake hose surface and the oxygen in the direct steam vulcanization vulcanization cylinder. The oxidation reaction makes the surface of the brake hose immaturely vulcanized, which will reduce the flex fatigue resistance, dynamic pulse resistance, ozone resistance, and high and low temperature resistance of the brake hose product. Many manufacturers have also been using high-temperature vulcanization to fix the hose. This type of vulcanization rack cannot vulcanize the inside of the hose, and the single-sided vulcanization takes a long time and is inefficient. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a rubber tube secondary vulcanization system which has a reasonable structure, good use effect and can quickly vulcanize the hose.

[0004] To achieve the above-mentioned purpose, the technical solution provided by the present invention is: a rubber tube secondary vulcanization system, which includes an organic shell, wherein more than 2 rows of columns are installed in the shell, and more than 2 layers of supporting beams are installed on the columns from top to bottom, and pipe row wheels are evenly distributed on the top of the supporting beams. A vulcanization frame is movably installed on the pipe row wheel, and the vulcanization frame is connected to a water supply joint. Fans are installed on the side walls of the inner cavity of the shell, and heating pipes are provided on the outside of the air outlet of the fan. A high-temperature water tank and a negative pressure pump are installed on the ground outside the shell, and the high-temperature water tank is connected to the water supply joint through a water supply pipe, and the negative pressure pump is connected to the inner cavity of the shell through a negative pressure pipe.

[0005] The heating pipe is installed in a serpentine or U-shaped manner outside the air outlet of the fan, and a heating plate is arranged on the surface of the heating pipe, and the heating plates are evenly distributed on the surface of the heating pipe in a spiral shape.

[0006] The vulcanization frame is in a square frame shape formed by connecting hollow metal pipes. A plurality of water source plug connectors are distributed on the inner cavity walls on both sides of the vulcanization frame, and the water source plug connectors are in a conical cylindrical shape. The bottoms of both ends of the vulcanization frame are provided with lower connecting beams extending vertically downward, and a lower water pipe support beam is connected between the two lower connecting beams. The tops of both ends of the vulcanization frame are provided with upper connecting beams extending vertically upward, and an upper water pipe support beam is connected between the two upper connecting beams.

[0007] After adopting the above scheme, the present invention connects the two ends of the hose (rubber hose) to be vulcanized to the corresponding water source plug connectors respectively. When the hose is short, it can be connected between the two water source plug connectors on the same side. When the hose is long, it can be connected between the water source plug connectors on different vulcanization racks. When the hose is long, the hose is supported by the lower water pipe joist or the upper water pipe joist to prevent the hose from piling up, overlapping or falling out. After the hose is plugged in place, high-temperature hot water is supplied to the water supply connector through the high-temperature water tank through the water supply pipe, and the hose is filled with water through the water source plug connector. The first-stage vulcanization is carried out; during the vulcanization, the heating tube generates heat to increase the temperature inside the casing. The spiral heating plate can quickly dissipate the heat of the heating tube to the entire casing. While heating, a flowing wind vortex is formed in the casing through the fan, thereby preventing local overheating in the casing. After heating to a certain temperature, the casing is evacuated through a negative pressure pump and a negative pressure pipe, and secondary rapid vulcanization is carried out through the negative pressure in the casing and the high temperature inside and outside the hose. The structure after adopting this scheme is reasonable, the use effect is good, and the hose can be rapidly vulcanized. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention will be further described below in conjunction with all the accompanying drawings. The preferred embodiments of the present invention are as follows: Figure 1 To Attachment Figure 3 A rubber tube secondary vulcanization system described in this embodiment includes an organic shell 1, wherein more than two rows of columns 2 are installed in the shell 1, and more than two layers of supporting beams 4 are installed on the columns 2 from top to bottom, and pipe row supporting wheels 6 are evenly distributed on the top of the supporting beams 4. A vulcanization frame 3 is movably installed on the pipe row supporting wheels 6, and the vulcanization frame 3 is connected to a water supply joint 12. Fans 8 are installed on the side walls of the inner cavity of the shell 1, and a heating pipe 7 is provided outside the air outlet of the fan 8. A high-temperature water tank 9 and a negative pressure pump 10 are installed on the ground outside the shell 1, and the high-temperature water tank 9 is connected to the water supply joint 12 through a water supply pipe, and the negative pressure pump 10 is connected to the inner cavity of the shell 1 through a negative pressure pipe 11.

[0012] The heating tube 7 is installed in a serpentine or U-shaped manner outside the air outlet of the fan 8. A heating sheet 13 is provided on the surface of the heating tube 7. The heating sheet 13 is spirally evenly distributed on the surface of the heating tube 7. The vulcanization frame 3 is a square frame formed by connecting hollow metal pipes. A plurality of water source plug connectors 5 are distributed on the inner cavity walls on both sides of the vulcanization frame 3. The water source plug connectors 5 are in a cone shape. The bottom of both ends of the vulcanization frame 3 is provided with a vertical downward lower connecting beam, and a lower water pipe support beam 14 is connected between the two lower connecting beams. The top of both ends of the vulcanization frame 3 is provided with a vertical upward upper connecting beam, and an upper water pipe support beam 15 is connected between the two upper connecting beams.

[0013] After adopting the above scheme, the two ends of the hose (rubber hose) to be vulcanized are respectively connected to the corresponding water source plug connectors. When the hose is short, it can be connected between the two water source plug connectors on the same side. When the hose is long, it can be connected between the water source plug connectors of different vulcanization racks. When the hose is long, the hose is supported by the lower water pipe support beam or the upper water pipe support beam to prevent the hose from piling up, overlapping or falling out. After the hose is inserted in place, high-temperature hot water is supplied to the water supply connector through the high-temperature water tank through the water supply pipe, and the hose is filled with water through the water source plug connector to perform primary vulcanization. During vulcanization, the heating tube heats up, so that the temperature in the casing increases. The spiral heating sheet can quickly dissipate the heat of the heating tube to the entire casing. While heating, a flowing wind vortex is formed in the casing through the fan, thereby preventing local overheating in the casing. After heating to a certain temperature, the casing is evacuated by a negative pressure pump and a negative pressure pipe, and secondary rapid vulcanization is performed through the negative pressure in the casing and the high temperature inside and outside the hose. The structure after adopting this scheme is reasonable, the use effect is good, and the hose can be quickly vulcanized.
