Description

Technical Field

[0001] The invention relates to the field of shaping, and in particular to a tire bead shaping device. Background Art

[0002] The tire bead is the part that is in close contact with the rim, and its shape directly affects the air tightness of the tire. If the bead shape is irregular, with bulges, depressions or deformations, the tire and the rim will not fit tightly, making it easy for air to leak. In the case of bulges in the bead, if there is a problem in the rubber mixing process during the tire bead manufacturing process, it may lead to uneven distribution of the rubber components. Therefore, during the subsequent vulcanization, the degree of vulcanization in each area will be different, the rubber hardness will increase, and the volume may expand slightly, thereby forming a bulge on the bead surface. At the same time, during the manufacturing process, if the surface of the mold is not smooth enough, the manufactured bead surface will also have bulges. In order to improve the safety of tire use and the yield rate of factory delivery, relevant bead shaping equipment is required to be used in conjunction.

[0003] After searching, the patent document with publication number CN205022017U discloses a tire bead shaping device, including a side frame, a base plate, a cross bar, a bracket, a fixing rod, a clamp, a cylinder I and a cylinder II. The base plate is fixedly connected to the four corners of the bottom of the side frame, and a plurality of cross bars are fixedly connected to the middle of both sides of the side frame and the distance between every two cross bars is equal. The bracket is fixedly connected to the cross bar. The patent can apply tension to the deformed tire to achieve the shaping of the bead.

[0004] The above prior art often has the following problems when used:

[0005] When the existing tire bead shaping device is in use, stretching measures are used to shape the deformed bead. Such shaping measures have low operability and low applicability. They can only be used for some slight deformations and are not suitable for situations where the bead surface has many protrusions. At the same time, when shaping the bead, the necessity of shaping should be considered. If the deformation degree of the bead has reached the scrap standard, shaping is not economical. There should be corresponding testing measures to remind the staff, thereby improving the economic benefits of the device and being more in line with actual usage scenarios. Summary of the invention

[0016] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0017] 1. Through the shaping mechanism, a heat shaping measure can be provided for the tire bead with bulges on the surface, so as to remove the bulges on the tire bead surface. At the same time, during shaping, it can be adaptively adjusted according to the bulge degree of the tire bead surface. During the heat shaping process, the electric heater will first contact the bulge on the tire bead surface. After contact, the bulge degree of the tire bead will determine the working power of the electric heater. The greater the bulge degree, the greater the working power of the electric heater, so that it has a higher temperature and a wider heat transfer range. The rubber has a certain plasticity after heating, and cooperates with the subsequent extrusion roller to realize the shaping operation of the bulge on the tire bead surface. At the same time, the extrusion force of the extrusion roller will also be adaptive according to the bulge degree. When the bulge degree is greater, the extrusion roller should also provide greater pressure to better remove the bulge on the tire bead surface, which is more in line with the actual usage scenario and has a higher degree of automation.

[0018] 2. The tire bead positioning mechanism is set up to realize the positioning and fixation of the tire bead to be shaped. Tires of different uses and different models have different sizes. Therefore, when shaping them, in order to ensure the efficient shaping operation, it is necessary to have a positioning and fixing measure with strong applicability, which can be applicable to tire bead of different sizes. The tire bead positioning mechanism is not only applicable to tire bead of different sizes, but also can ensure its good stability after the tire bead is positioned and fixed, and then can cooperate with the shaping mechanism to realize efficient shaping operation, which is beneficial to improve the working efficiency of the device.

[0019] 3. Through the detection mechanism set up, it is possible to detect and determine the necessity of tire bead shaping. The detection mechanism has two detection items. One is to detect the degree of bulge. When the bulge on the tire bead surface is too large and the shaping conditions are no longer met, the detection mechanism can detect and alarm by itself. The other is for the number of bulges. After the tire bead leaves the factory, if the surface bulges exceed a certain number, it will reach the scrap standard and is no longer eligible for shaping. The detection mechanism can also detect and alarm by itself, thereby avoiding blind tire bead shaping operations, which is beneficial to improving the working efficiency and economic benefits of the device.

The two No. 2 springs 35 are respectively sleeved on the two No. 2 guide rods 33, and the two No. 5 springs 55 are respectively sleeved on the two No. 3 guide rods 54.

[0033] The working principle of the present invention is as follows: when it is necessary to use a device to shape a tire bead with a protrusion on the surface, the tire bead positioning mechanism first completes the positioning and fixing of the tire bead, and the tire bead to be fixed is sleeved on the outside of the No. 3 fixing plate 24, the No. 1 electric push rod 25 and the No. 2 supporting roller 26, and then the surface of the tire bead is pressed against the rotating roller 23. After completion, the No. 1 electric push rod 25 is started, and the output end of the No. 1 electric push rod 25 will drive the No. 2 supporting roller 26 to press against the inner wall of the tire bead, and cooperate with the rotating roller 23 to achieve preliminary fixation of the tire bead, and then the two-way threaded rod 16 is rotated. The two-way threaded rod 16 rotates, and the two nuts 17 are restricted by the two limiting through grooves 18 and the limiting rod 19, and then move toward each other along the two-way threaded rod 16. The two nuts 17 are connected to the two-way threaded rod 16. The two limit rods 19 drive the two No. 1 support rollers 20 to move toward each other, thereby completing the positioning and fixing of the tire bead between the two, and it has strong applicability and can be suitable for tire bead of different sizes. After completing the above positioning and fixing, start the motor 21, and the motor 21 drives the rotating roller 23 to rotate through the rotating shaft 22, and then drives the tire bead to rotate around its center through friction. The No. 2 support roller 26 makes the tire bead always in contact with the rotating roller 23, and the friction force always exists. The two No. 1 support rollers 20 assist the tire bead so that it will not deviate when rotating, thereby providing the possibility for subsequent shaping. During the subsequent shaping, the speed of the motor 21 should be slower to better realize the shaping operation. Before the tire bead rotates, the No. 2 support plate 29 and the No. 3 support plate 30 are controlled by the No. 2 electric push rod 28.The side wall of the test rod 32 is fitted with the surface of the tire bead to detect the necessity of shaping. There are two types of detection items of the detection mechanism, including bulge degree detection and bulge quantity detection. When the bulge degree on the tire bead surface is too large or the quantity is too large, the detection mechanism will alarm, so that the tire bead will no longer be shaped, thereby improving economic benefits. During operation, the bulge degree is detected by running the detection component. When the tire bead rotates, the bulge contacts the test rod 32, which will push it to move upward until the bulge passes over the test rod 32. Under the action of the two No. 2 springs 35 between the test rod 32 and the No. 4 support plate 31, the test rod 32 will return to the detection position for the next detection. When the bulge pushes the test rod 3 2 moves upward, the push plate 34 will also move upward with the test rod 32, thereby causing the No. 1 touch block 37 to move toward the No. 1 touch switch 36. The moving distance of the test rod 32 is proportional to the degree of protrusion. Therefore, when the degree of protrusion is too large, the No. 1 touch block 37 will contact the No. 1 touch switch 36 and give it a pressure, thereby activating the switch to energize the alarm light 38 to realize the alarm function. The quantity detection component counts and detects the number of protrusions. When the protrusion raises the height of the test rod 32, the push plate 34 drives the push rod 41 to move upward, and then the push rod 41 pushes the detection rod 40 upward through the No. 1 hole 44. When the detection rod 40 moves upward, the bottom slope of the No. 2 hole 45 gives an inclined The oblique card block 47 is pushed to slide toward the groove 46 until the oblique card block 47 retracts into the groove 46, and the detection rod 40 continues to move upward. When the next No. 2 hole 45 corresponds to the oblique card block 47, the oblique card block 47 will pop out under the action of the No. 4 spring 48, and then engage with the detection rod 40 again. When the protrusion is no longer in contact with the test rod 32, the test rod 32 moves downward. At this time, the push rod 41 will also disengage from the No. 1 hole 44, and continue to move downward. Under the action of the No. 3 spring 43, it will engage with the next No. 1 hole 44. At this time, the detection rod 40 moves upward by the distance of one hole position, and the protrusion is counted by the final moving distance. The working principle is similar to the above. , the detection rod 40 drives the No. 2 touch block 53 to move toward the No. 2 touch switch 51, and the moving distance is proportional to the number of protrusions. If the tire bead rotates one circle or less than one circle, the No. 2 touch switch 51 turns on the alarm light 38, then the number of protrusions is too much and does not have an integer meaning. On the contrary, it has an integer meaning. The detection standard can also be changed. The reset rod 50 controls the movement of the oblique block 47, so that the detection rod 40 is disengaged from the engaged state, and the push rod 41 and the No. 1 hole 44 are disengaged from the engaged state. At this time, the detection rod 40 can move at will. The detection rod 40 controls the distance between the No. 2 touch block 53 and the No. 2 touch switch 51, so as to realize the control of the detection standard, which is highly practical;,

[0034] After completing the above detection, if the tire bead has the shaping significance, the subsequent shaping operation can be carried out, and the tire bead continues to rotate. At this time, the electric heater 6 and the cylinder 14 are started. When the tire bead rotates, the protrusion will contact the electric heater, and while being heated by the electric heater 6, it will also be pushed to move downward. The electric heater 6 drives the functional plate 5 to move, and then the two No. 1 guide rods 7 move, so that the No. 1 conductive ring 10 and the No. 2 conductive ring 11 move, and the No. 2 conductive ring 11 moves upward and slides upward on the variable resistance rod 9, which will reduce the resistance, and then at the same voltage, the current becomes larger, thereby increasing the working power of the electric heater 6. The working power of the electric heater 6 is proportional to the degree of contact with the protrusion. The greater the degree of protrusion, the higher the temperature of the surface of the electric heater 6, and the wider the heat transfer range. The tire bead rotates slowly, and the heating of the electric heater 6 makes the protrusion have a certain plasticity, and cooperates with the subsequent extrusion roller 15 to shape the protrusion to achieve self-adaptation. The heating adjustment is more in line with the actual usage scenario. At the same time, when the No. 1 guide rod 7 moves downward, the No. 1 conductive ring 10 will also slide downward on the variable resistance rod 9. The same as the above principle, the current connected to the solenoid valve 13 will also be larger, and the larger current of the solenoid valve 13 will cause the internal electromagnetic force to be larger. The electromagnetic force controls the movement of the valve core, and in the pneumatic system, the movement of the valve core of the solenoid valve 13 controls the flow direction of the gas, thereby determining the expansion and contraction of the cylinder 14. The greater the electromagnetic force, the greater the displacement of the valve core, and the larger the opening of the air intake channel, which increases the gas flow entering the cylinder 14 per unit time. That is to say, the greater the extension distance of the cylinder 14 per unit time, the greater the force acting on the protrusion, and the cylinder 14 controls the movement of the extrusion roller 15 to extrude and remove the heated protrusion, and the degree of protrusion is proportional to the extrusion force, and can automatically adapt according to the degree of protrusion, which is more in line with the actual usage scenario and is conducive to improving the shaping effect of the tire bead and the working efficiency of the device.
