Description

Technical Field

[0001] This utility model relates to the field of tire repair technology, specifically to a tire bead repair device. Background Technology

[0002] In the production and operation of giant all-steel radial tires in mining, many giant all-steel radial engineering tires suffer from bead cracking, missing pieces, and rubber defects due to adhesion and seizing during loading and unloading, resulting in significant waste. Meanwhile, tire bead repair can restore and reuse tires damaged by bead damage, thereby increasing their usability. Therefore, it is essential to effectively repair bead damage during tire use to extend tire service life. Utility Model Content

[0003] The purpose of this invention is to solve the problem of excessive waste caused by the adhesion and seizing of the bead during the loading and unloading of existing giant all-steel radial tires, resulting in bead cracking, missing pieces and glue, which cannot be repaired.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tire bead repair device, characterized in that: it includes a tray installed on a tire vulcanizing equipment for supporting the tire tread; a fixed baffle is provided on one side of the tray; a guide pin bracket is fixedly connected to the other side of the tray; an embedding hole is transversely opened on the guide pin bracket; a guide pin sleeve is installed in the embedding hole; a guide pin is slidably fitted in the guide pin sleeve; a movable baffle is fixedly connected to the end of the guide pin facing the fixed baffle through the guide pin bracket; and a temperature sensor is installed on the rib plate on the bottom surface of the tray.

[0006] A further improvement is that thermal grease is applied to the interface of the temperature sensor.

[0007] A further improvement is that the tray and the fixing baffle are integrally formed from 7075 aluminum alloy.

[0008] A further improvement is that the movable baffle is made of 7075 aluminum alloy.

[0009] A further improvement is that a baffle handle is fixedly installed at the center of one end face of the movable baffle facing the guide pin bracket, and the baffle handle is provided with a mounting hole.

[0010] A further improvement is that one end of the guide pin passes through the guide pin sleeve of the guide pin bracket and is welded to the mounting hole of the baffle handle.

[0011] A further improvement is that an electric heating plate is distributed on the side of the tray, fixed baffle, and movable baffle facing the tire, and each electric heating plate is equipped with a temperature controller.

[0012] A further improvement is that the tire vulcanizing equipment is equipped with an electricity meter and a vulcanization temperature recording instrument.

[0013] Compared with existing technologies, the above technical solution has the following advantages:

[0014] By using a movable baffle in conjunction with a tray for staggered clamping, a high clamping force is maintained. The tire bead is repaired by an electric heating plate. This eliminates the problem of tires being scrapped due to the lack of specialized equipment for repairing tire beads, effectively improving the tire's usability. Attached Figure Description

[0020] See Figures 1-3 As shown, the technical solution adopted in this specific embodiment is: a tire bead repair device, characterized in that: it includes a tray 1 installed on a tire vulcanizing equipment 8 for supporting the tire tread, a fixed baffle 7 is provided on one side of the tray 1, a guide pin bracket 2 is fixedly connected to the other side of the tray 1, an embedding hole is provided transversely on the guide pin bracket 2, a guide pin sleeve is installed in the embedding hole, a guide pin 3 is slidably sleeved in the guide pin sleeve, a movable baffle 4 is fixedly connected to the end of the guide pin 3 facing the fixed baffle 7 through the guide pin bracket 2, and a temperature sensor 6 is installed on the bottom rib of the tray 1.

[0021] Thermal grease is applied to the interface of the temperature sensor 6.

[0022] The tray 1 and the fixed baffle 7 are integrally formed from 7075 aluminum alloy.

[0023] The movable baffle 4 is a 7075 aluminum alloy baffle.

[0024] The movable baffle 4 is fixedly provided with a baffle handle 5 at the middle of one end face of the guide pin bracket 2, and the baffle handle 5 is provided with a mounting hole.

[0025] One end of the guide pin 3 passes through the guide pin sleeve of the guide pin bracket 2 and is welded to the mounting hole of the baffle handle 5.

[0026] Among them, an electric heating plate is distributed on the side of the tray 1, the fixed baffle 7, and the movable baffle 4 facing the tire, and each electric heating plate is equipped with a temperature controller.

[0027] The tire vulcanizing equipment 8 is equipped with an electricity meter and a vulcanizing temperature recording instrument.

[0028] Fabrication and installation work:

[0029] 1) Pallet manufacturing: Use a 3D scanner to create a 3D model of the tire bead area, select 7075 aluminum alloy ingots, and use a machining center to cut the tire tread pallet body and guide pin bracket.

[0030] 2) Fabrication of the movable baffle: Using 3D modeling data, select 7075 aluminum alloy ingots and use a machining center to cut the movable baffle;

[0031] 3) Machining and installing guide pin sleeves: Machining guide pin insertion holes at the guide pin bracket location to insert the guide pin sleeves;

[0032] 4) Install guide pins for the movable baffle: Machining guide pin mounting holes on the movable baffle, installing and welding the guide pins to ensure the baffle moves freely;

[0033] 5) Install temperature sensors: Embed and install temperature sensors at various points on the ribs of the tire tray body and apply thermal grease to the interfaces.

[0034] 6) Three custom-made electric heating plates will be manufactured by a professional electric heating plate manufacturer according to the provided design (e.g., Figure 3 (As shown).

[0035] The working principle of this utility model is as follows: A fitting tray and movable baffle are precision machined by CNC. The movable baffle is used for staggered clamping to maintain a high clamping force. The tire bead is repaired by electrothermal heating through an electric heating plate. Temperature sensors, three temperature controllers, and a vulcanization temperature recorder are set up for differentiated adjustment and traceable recording of vulcanization time. The vulcanization temperature of different areas of the three parts is controlled separately. This eliminates the predicament of tire beads being scrapped due to lack of specialized equipment for repair, and effectively improves the use value of the tire.
