Description

Technical Field

[0001] The present invention relates to the field of vulcanizing machines, and particularly to a translational capsule vulcanizing machine and a method for using the same. Background Art

[0002] As the main type of vulcanizing machine for bias tires in small and medium-sized tire enterprises, the flat capsule vulcanizing machine has a series of advantages such as simple operation, low labor intensity, good equipment stability, high product qualification rate, and low cost investment. However, when dealing with the production of special tires, there are problems such as a relatively small operating space, rapid wear of seals, and certain safety hazards. The existing flat vulcanizing machine has a relatively small operating space when loading and unloading tire embryos. When vulcanizing low-section tires, the length of the tire blank is relatively large, the operation difficulty during the tire loading process is high, the labor intensity is high, and defective products are likely to occur. At the same time, the stroke of the oil cylinder is too long, resulting in too fast seal wear. When the external oil pressure pipeline fails and relieves pressure, it is extremely easy to cause the capsule to break, posing a certain potential danger.

[0003] Therefore, how to provide a vulcanizing machine with a short oil cylinder stroke and a large loading and unloading operation space is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of the present invention is to provide a translational capsule vulcanizing machine and a method for using the same, which can shorten the oil cylinder stroke and increase its loading and unloading operation space.

[0005] To achieve the above purpose, the present invention provides a translational capsule vulcanizing machine, including: a frame, an upper mold, and a lower mold; the upper mold is arranged inside the frame through an upper mold lifting oil cylinder and can be lifted and lowered in the vertical direction;

[0006] The lower mold is arranged below the upper mold through a lower mold translation device, and the lower mold translation device is used to drive the lower mold to move horizontally into and out of the frame; a mold closing and pressurizing device for realizing pressurization is arranged inside the frame, and a pressure transfer plunger for shortening the pressurization stroke is arranged above the upper mold.

[0007] Optionally, the lower mold translation device includes: a translation plate, a linear guide rail mechanism, and a servo motor;

[0012] The push-pull oil cylinder is arranged at the top inside the frame and can move horizontally along the plane where it is located. The pressurizing oil cylinder is arranged below the push-pull oil cylinder to pressurize the pressure transmission plunger.

[0013] Optionally, support plates for supporting the lower die translation device are arranged on both sides of the frame.

[0014] The present application also provides a method for using a translation capsule vulcanizer, which is applied to the translation capsule vulcanizer in any one of the above items, and includes: moving the lower die out of the inside of the frame through the lower die translation device, and loading a tire into the lower die;

[0015] Moving the lower die with the green tire blank back into the inside of the frame and aligning it with the vertical position of the upper die. The upper die lifting oil cylinder drives the upper die to descend and fit seamlessly with the lower die; the mold clamping and pressurizing device fits the pressure transmission plunger located above the upper die to achieve pressurization of the upper die and the lower die.

[0016] Compared with the above background technology, the present invention is provided with a frame, an upper die and a lower die; the upper die is arranged inside the frame through the upper die lifting oil cylinder and can move up and down along the vertical direction; the lower die is arranged below the upper die through the lower die translation device, and the lower die translation device can drive the lower die to move horizontally, so as to realize the lower die moving into and out of the inside of the above frame, and completing tire loading and unloading outside the frame, greatly improving the operation space. When the lower die translation device moves the lower die back into the inside of the frame after installing the tire and sets it corresponding to the vertical position of the upper die, the upper die lifting oil cylinder drives the upper die to fit seamlessly with the lower die, and then the mold clamping and pressurizing device arranged inside the frame pressurizes the pressure transmission plunger above the upper die, reducing the pressurization stroke, greatly reducing the wear of the oil cylinder and the seal, and eliminating potential safety hazards. The above translation capsule vulcanizer improves the service life of the oil cylinder seal, reduces the oil cylinder maintenance rate; improves the equipment stability, expands the operation space, and reduces the labor intensity of employees; and has better versatility, especially suitable for the use of special bias tires.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0026] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Refer to the attached drawings of the specification Figure 1 , attached Figure 1 Schematic diagram of the structure of the translation capsule vulcanizer provided by the embodiment of the present invention, including: frame 1, upper die 2 and lower die 3; the above - mentioned upper die 2 is connected inside the frame 1 through the upper die lifting oil cylinders 4 on both sides of the frame 1, and the upper die 2 can be lifted and lowered in the vertical direction through the upper die lifting oil cylinders 4. The above - mentioned lower die 3 is arranged below the upper die 2 through a lower die translation device, and the lower die translation device can drive the lower die 3 arranged above it to move horizontally, so as to realize the movement of the lower die 3 into and out of the inside of the above - mentioned frame 1.

[0028] In the prior art, the operating space for assembling and disassembling tires is between the upper mold and the lower mold. To increase the operating space, only the height of the vulcanizer can be increased to get rid of the space limitation of the upper mold. In contrast, the above-mentioned structural design of moving the lower mold 3 out of the frame 1 has significantly increased the operating space for assembling and disassembling tires and got rid of the obstruction of the upper mold 2. After the lower mold translation device moves the lower mold 3 after installing the tire back into the frame 1 and sets it corresponding to the vertical position of the upper mold 2, the upper mold lifting oil cylinder 4 drives the upper mold 2 to fit seamlessly with the lower mold 3, and then it is pressurized by the mold clamping and pressurizing device installed inside the frame 1. There is a pressure transfer plunger 11 arranged above the above-mentioned upper mold 2, and the above-mentioned pressure transfer plunger 11 contacts the above-mentioned pressurizing oil cylinder 10, which is used to shorten the pressurizing stroke. As the most important pressurizing and pressure-holding equipment of the vulcanizer, the oil cylinder generally has problems such as high pressure and high telescopic frequency. The stroke of the existing vulcanizer oil cylinder is about 100 cm. After long-term use, there are slight deviations in the verticality of the oil cylinder, and at the same time, the seal of the oil cylinder wears more seriously, and the possibility of cylinder expansion is high. In the translation capsule vulcanizer of the present application, a pressure transfer plunger 11 is arranged directly above the upper mold 2, and the lower surface of the pressure transfer plunger 11 is integrally connected to the upper mold 2; when the translation capsule vulcanizer starts to work, the pressure transfer plunger 11 moves downward with the upper mold 2 to the target position and is pressurized by the mold clamping and pressurizing device. The mold clamping and pressurizing device uses a small-stroke oil cylinder, reducing the original oil cylinder stroke to about 2 cm, greatly reducing the wear of the oil cylinder and the seal, and eliminating potential safety hazards. When the pressure reaches the set pressure, the vulcanization system of the translation capsule vulcanizer itself starts to vulcanize the tire. The setting method and usage method of the vulcanization system of the translation capsule vulcanizer itself can refer to the prior art and will not be elaborated here. The above-mentioned translation capsule vulcanizer improves the service life of the oil cylinder seal, reduces the oil cylinder maintenance rate; improves the equipment stability, expands the operating space, reduces the labor intensity of employees; and has better versatility, especially suitable for the use of special bias tires.

[0029] Further, referring to the attached drawings of the specification Figure 2 , the attached Figure 2 is a schematic structural diagram of the translation capsule vulcanizer from another perspective provided by the embodiment of the present invention, including: the above-mentioned lower mold translation device includes: a translation plate 5 and a linear guide rail mechanism 6; the upper part of the above-mentioned translation plate 5 is used to place the lower mold 3, and the linear guide rail mechanism 6 is used to drive the translation plate 5 to move horizontally. The two extreme positions of the horizontal movement of the above-mentioned translation plate 5 are respectively the horizontal position corresponding to the upper mold 2 inside the frame 1 and the outer end of the outer guide rail 12; setting the extreme position inside the frame 1 is used to ensure that the corresponding matching position of the lower mold 3 and the upper mold 2 is easy to determine, and setting the extreme position at the outer end of the outer guide rail 12 can ensure sufficient operating space for the installation and disassembly of the tire.

[0030] The horizontal movement range and limit positions of the above-mentioned translation plate 5 are not limited to the above one type and can be specifically changed according to actual requirements, which will not be elaborated herein.

[0031] The driving method of the above-mentioned translation plate 5 is not limited to using the linear guide rail mechanism 6. Any driving method that can satisfy driving the translation plate 5 and the lower mold 3 to move into and out of the inside of the frame 1 in the horizontal plane to realize the installation and disassembly of the tire can be replaced, and the same technical effect can be achieved, which will not be elaborated herein.

[0032] Further refer to the attached drawings of the specification Figure 3 drawing, the attached Figure 3 is a schematic diagram of the lower mold translation device provided by the embodiment of the present invention, including: The above-mentioned lower mold translation device further includes: a lower mold lifting oil cylinder 7, and the above-mentioned lower mold lifting oil cylinder 7 is used to lift or lower the vertical height of the above-mentioned translation plate 5 to ensure that it moves on the same horizontal straight line as the above-mentioned external guide rail 12.

[0033] The above-mentioned lower mold lifting oil cylinder 7 can be replaced with other types of lifting mechanisms according to requirements, as long as it can satisfy lifting the above-mentioned translation plate 5 along the vertical direction to the same horizontal straight line as the above-mentioned external guide rail 12, which will not be elaborated herein.

[0034] Further, the above-mentioned lower mold translation device further includes: a protective plate 8, and the above-mentioned protective plate 8 is arranged around the above-mentioned translation plate 5 to protect the lower mold 3 from moving stably following the movement of the translation plate 5 and prevent its position from shifting.

[0035] Further, refer to the attached drawings of the specification Figure 4 drawing, the attached Figure 4 is a schematic diagram of the cooperation between the pressurizing oil cylinder and the pressure transmission plunger provided by the embodiment of the present invention, including: The above-mentioned mold clamping and pressurizing device includes a push-pull oil cylinder 9 and a pressurizing oil cylinder 10; the above-mentioned push-pull oil cylinder 9 is arranged on the top end face inside the above-mentioned frame 1 and can move along the end face where it is located, and the pressurizing oil cylinder 10 is arranged at the bottom of the push-pull oil cylinder 9 and moves horizontally with it. When the translation capsule vulcanizing machine is not started, the push-pull oil cylinder 9 drives the pressurizing oil cylinder 10 to be arranged above the side of the upper mold 2 to save internal space; when the translation capsule vulcanizing machine starts, the above-mentioned upper mold lifting oil cylinder 4 drives the upper mold 2 to descend and closely fit with the lower mold 3 completed with tire assembly. At this time, the above-mentioned push-pull oil cylinder 9 moves along the end face where it is located to move the pressurizing oil cylinder 10 directly above the upper mold 2 and pressurize the upper mold 2 and the lower mold 3.

[0038] The lower die 3 loaded with the green tire is moved back into the frame 1 and aligned with the vertical position of the upper die 2. The upper die lifting oil cylinder 4 drives the upper die 2 to descend and fit seamlessly with the lower die 3; the mold clamping and pressurizing device fits the pressure transfer plunger 11 located above the upper die 2 to realize pressurization of the upper die 2 and the lower die 3.
