How to use the vacuum tire scraper, how to scrap the car tire without a tire scraper?

First of all, the equipment and sundries that hinder the operation on and near the tire scraper should be removed, and all parts of the machine should be checked to see if they are normal. Secondly, when picking the tire, completely drain the air in the tire and remove all the lead on the steel rim.

Put the tire in the tire extrusion position, use the wheel rim to detach the hoof to compress the tire and make it separate from the steel ring, so that the tire and the steel ring are completely separated, and the hands and feet should be prevented from going deep into the extrusion arm during the extrusion process. Pay special attention to be sure to deflate the tires when performing this step.

Lift the tires on the disassembly table, at this time should avoid bumping the equipment, after the tires are placed, press the pedal to support (or clamp) the steel rim, and do not allow fingers to probe whether the steel rim is aligned.

Install and disassemble the bird head, pay attention to the fastening and the position of the bird head from the steel ring. The best position is centimeters, and it is fastened after adjustment.

In the process of disassembling and assembling tires, when using a crowbar to pick the edge of the tire to the bird's head, you should pay attention to the direction and strength of the crowbar, and never allow your hand to go deep into the gap of the prying.

At this time, press the turning pedal to rotate the tire scraper table clockwise, and the outside of the tire can be removed.

In the same way, the inside tire can be removed. Pull the tires out of the rim.

Tire loading process. First of all, the first step is to clean the wheel steel to ensure that there is no dirt to cut the tire. (You can consider applying some lubricating materials such as foam water, soapy water, etc., except for oil).

When I put in a specification tire, the tire and the wheel steel (hub) are matched. The method of installing the bird head and the steps of disassembling it have been all the way, and it is tightened after adjustment.

Calculate the part of the tire outside with clockwise, one side with the tail and the other with the top of the bird's head. Squeeze the tires by hand

The large tire breaker is hydraulic. Try to keep the head close to the rim when you disassemble it. While dismantling, replace the tire removal head and press down and move it outward.

The first step is to prepare the tools and equipment needed for the whole process of disassembling car tires, a tire wrench, a small hook, both of which can be found in the trunk of the car, and a jack.

The second step, the disassembly of the tire screw cap, take out the small hook, hook the hole of the screw cap with a small hook, and then pull it out to remove the screw cap, a total of 5, take it off one by one, the third step, take off the screw cap to be placed in a small box to avoid loss.

Fourth, the initial loosening of the car tire screw, take out the tire wrench, use the tire wrench stuck on the screw, and then turn counterclockwise to loosen all 5 screws.

The fifth step is to support the place where the tire needs to be disassembled, take out the jack, find the support point of the stiffener in the place of the chassis, and then use the jack to support the vehicle.

Sixth, take out the tire wrench again, disassemble the 5 screws that were loosened before to fix the tire, and put the disassembled screws in the previous small box.

Step 7: We can remove the tires of the car, hold both sides of the tires of the car with both hands, and then lift them out.

First of all, the tires should be cleaned comprehensively, including the surface of the tire, the contact surface between the wheel and the rim and the bolts and nuts on the wheel, and the rust, slag and mud on the wheel. The main purpose of cleaning is: first, to reduce the impact of dirt on the repairer in the process of disassembly and assembly; The second is to reduce the amount of dirt entering the inside of the tire and reduce unnecessary secondary injury.

2.Lubricate the grooves of bolts and nuts before dismantling to facilitate disassembly and reduce wear. Use a matching torque wrench, leave a spacing of 2-3 nuts, and disassemble them in the order of the diagonal, which can effectively reduce the irregular force on the bolt and reduce the fatigue loss of the parts.

If you choose a motorized wrench, you need to adjust the air pressure, which depends on the size of the nut.

3.Place the lock ring of the wheel upwards to release the air from the tire, and push out the valve when the inner tube tire is deflated. Make pairing marks on the tires and rims. Note: The gas in the tire must be cleaned to avoid accidental injury accidents in subsequent operations.

4.Insert the straight guide vane plate between the rim ring and the tire, and press down the bead of the tire; Insert the vane guide plate at the gap formed so that the end of the vane guide plate is supported in the flange ring, and the top of the shaft head rests on the straight guide vane plate.

5.Remove the tapered edge of the lock ring from the tire by pressing down the tire bead on one side and moving the straight and curved vane plates along the circumference of the wheel on the other side.

6.insert the end of the straight guide vane plate into the notch of the locking ring, and press the locking ring out of the groove; Lift the locking ring upwards, support the bent vane plate in the rim ring, and insert the end of the straight vane plate into the lower end of the locking ring; Hold the lock ring in your hand and remove the lock ring from the groove of the rim with the straight guide vane plate.

7.Take out the rim ring, flip the wheel, take off the side of the tire from the wheel with the help of straight and curved vane plates, and then place the wheel vertically, first take out the rim from the tire, and decisively beat the rim from the tire by punching along the locking part of the wheel with a hammer. If you have a tube, you can take out the inner tube.

Although many tire repair shops now have professional disassembly tools and even professional machinery and equipment, such as: special tire removal machine for truck tires. But the principle of disassembly is the same, and you must be careful during operation

1.When disassembling the tires to be replaced, it is important to note that you should not use a jack when you come up.

To lift the car up, you should first use a socket wrench.

Place the tire set screws diagonally.

Unscrew the sequence and then use a jack to lift the vehicle partially. If you lift the car first, you will find that you cannot unscrew the set screws because there is no force point.

2.When disassembling the fixed wheel screws, pay attention to the direction of force: the counterclockwise direction is loosening; Tighten in a clockwise direction. In addition, since the screws that hold the wheels are tightened, we can rely on the strength of the whole body.

3.After loosening the screws one by one, we can use the jack to partially lift the vehicle. When using a jack, pay attention to the fact that there are card slots for placing jacks on both sides of the bottom of the car, and be sure to place the jacks in the card slots to avoid accidents.

4.After the jack is propped up, the loosened screws are easily unscrewed in turn, and then the tire can be removed as a whole, which means that the tire disassembly is successfully completed.

First, the name of the training project: tires.

Second, the purpose of the training project: tire inspection and the use of tire scraper.

3. The equipment to be prepared for the training project: a tire scraper, a number of tires; A number of tools.

Fourth, the training process.

Overhaul: 1Check the tread pattern depth.

90% of the whole problem of the tire is in the last 10% of its life, excessive wear: easy to burst, the stability of the car handling deteriorates, when the car is driving at high speed in the rain, because all the water cannot be excluded from the tire, the tire will slide on the water film formed between the tread, causing the car to lose control. When the pattern on the crown of the car tire is 2mm---3mm, it should be stopped.

Measure the depth of the pattern with a depth gauge) Fault diagnosis of wheels and tires 1Abnormal wear and tear.

Shoulder or tread wear: Shoulder wear caused by insufficient inflation. Over-inflation causes wear in the middle of the tread 2Inner wear or outer wear (!) When cornering at too high speeds, the tires slip and cause diagonal wear.

2) The deformation of the suspension components or the excessive clearance affects the front wheel alignment, causing abnormal wear and tear (3) If one side of the tread wears faster than the other side, the main reason is 3Toe-in wear and toe-in wear.

1) Feathered wear of the tread. Excessive toe-in is mainly caused by improper toe-in adjustment 1 that forces the tire to slide outward, and causes the contact surface of the tread to drag inward on the road surface, causing toe-in wear.

2) Excess toe-in can pull the tire inward and cause the tread to drag outwards on the road, causing toe-in wear.

4. Front and rear end wear, patchy wear, etc. The use of a tire lifter and a barometer.

The emergence of the tire scraper prompts the maintenance personnel to no longer have to spend a lot of effort to pick the tire by hand, but for friends who have learned about the tire scraper, how to use the tire scraper has become a difficult point, and the non-standard application of the tire scraper will also be very easy to break the tire lip. Today, let's take a look at the operation method of the tire scraper** to see.

The process of removing the tire of the tire scraper:

1. First of all, you must unload the tires from the car, deflate, and then eliminate the counterweight on the edge of the steel rim.

2. Because the edge of the tire is placed in the seam of the steel rim, we must increase some force to leave the tire edge and the steel rim in the seam, so as to be able to carry out the actual operation in the future. Put the tire into the pressure shovel and the tire leather, place the pressure shovel between the steel ring and the tire, and then press the pedal vigorously to separate the tire edge from the steel ring.

3. Put the tire on the work table and clamp it tightly, and wipe it on the edge of the steel ring with thick foam liquid to prevent damage to the tire caused by disassembly.

4. Use a crowbar to warp the edge of the tire and pry it to the top of the disassembly head, the crowbar does not need to be removed, and the crowbar can be removed after trampling the pedal to turn the tire in a clockwise direction.

5. At this time, one side edge of the tire has been completely rid of the steel rim, and the other side is the same as the mode. Use a crowbar to warp the edge of the tire and pry it to the top of the disassembly head, the crowbar does not need to be removed, and the pedal makes the tire rotate in a clockwise direction after taking off the crowbar according to the situation, and the tire is basically picked.

Tire loading process of tire scraper:

1. Fix the steel rim on the large turntable, and wipe the edges of the tires on both sides with thick foam.

2. Place the edge of the tire on the steel rim, and rotate the wheel wheel after pressing the edge with the disassembly head and closing the edge early.

3. After one side of the tire is installed, the other side basically uses the same method to complete the safety.

The condition of the broken tire lip is basically due to the non-standard application of the tire scraper and the lack of proficiency in the operation steps.
