Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, specifically to a central mechanism quick capsule changing device. Background Technology

[0002] The bladder is a key component in the tire vulcanization process, used to transport high-temperature, high-pressure media to shape and vulcanize the tire carcass. Due to repeated stretching, folding, and thermal cycling, the bladder is prone to aging and rupture, with an average lifespan of only about 200–300 vulcanization cycles, requiring frequent replacement.

[0003] Traditional replacement of the center mechanism capsule uses a T-thread connection to the lower clamp. Usually, after cooling, the lower clamp needs to be manually removed by rotating it with a special lever tool. This is time-consuming, labor-intensive, and can easily damage the seal, affecting tire quality. Utility Model Content

[0004] The purpose of this invention is to provide a central mechanism for rapid capsule changing, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a central mechanism for rapid capsule changing, comprising:

[0006] The lower clamping plate has arc-shaped T-shaped slots on both the left and right sides of its lower side. One end of the arc-shaped T-shaped slot is a locking end, and the other end is an unlocking end. A pin insertion hole is provided at the unlocking end of the arc-shaped T-shaped slot, and a countersunk hole is provided at the locking end of the arc-shaped T-shaped slot.

[0007] The ring seat has locking pins slidably nested on both its left and right sides. The upper part of the locking pin is slidably nested in a corresponding arc-shaped T-groove. A cylinder is connected to the bottom of the ring seat corresponding to the position of the locking pin. A hydraulic cylinder is connected to the bottom end of the cylinder. A locking rod is connected to the telescopic end of the hydraulic cylinder. The locking rod is connected to the locking pin.

[0008] Furthermore, the lower part of the locking pin is cylindrical, and the upper part of the locking pin has a T-shaped cross-section when viewed from the front. The upper part of the locking pin matches the pin insertion hole, ensuring that the locking pin can be inserted into the arc-shaped T-shaped slot through the pin insertion hole. The T-shaped head of the locking pin matches the countersunk hole, which increases the contact area between the locking pin and the arc-shaped T-shaped slot when locking, thereby improving the stability and reliability of locking.

[0009] Furthermore, a guide positioning bushing is fixed at the position of the locking pin corresponding to the ring seat, and the lower part of the locking pin is slidably nested in the guide positioning bushing, which provides precise guidance for the movement of the locking pin.

[0010] Furthermore, the locking rod is nested inside the cylinder, saving space.

[0011] Furthermore, the ring seat is equipped with a positioning platform to ensure accurate alignment between the lower clamping plate and the ring seat, thereby improving the accuracy and efficiency of assembly.

[0012] Furthermore, an axial sealing ring is provided between the lower clamping plate and the ring seat to effectively prevent leakage of the internal pressure medium and improve safety.

[0013] Furthermore, the number of axial sealing rings is two, providing double sealing protection and improving sealing performance and safety.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. Through the design of the locking and unlocking ends of the arc-shaped T-shaped slot, combined with the cooperation of locking pins, oil cylinders, locking rods and other structures, the locking and unlocking operations of the capsule can be quickly realized, thereby greatly shortening the time required for capsule replacement;

[0016] 2. The entire locking and unlocking process mainly relies on the drive of the hydraulic cylinder. The operator only needs to control the movement of the hydraulic cylinder to complete the capsule replacement. The operation is simple and convenient, reducing the difficulty of operation and labor intensity, and further improving the efficiency of capsule replacement.

[0017] 3. The locking end of the arc-shaped T-slot is provided with a countersunk hole, which allows for a large contact area and stable locking force between the locking pin and the arc-shaped T-slot during locking, thus preventing the lower clamp from rotating and loosening.

[0018] 4. Two axial sealing rings are provided between the lower clamping plate and the ring seat, providing double sealing protection and improving sealing performance and safety. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figures 1 to 5 A central mechanism quick capsule changing device is shown, comprising:

[0029] The lower clamping plate 1 has arc-shaped T-shaped slots 2 on both the left and right sides of its lower side. One end of the arc-shaped T-shaped slot 2 is a locking end, and the other end of the arc-shaped T-shaped slot 2 is an unlocking end. A pin insertion hole is provided at the unlocking end of the arc-shaped T-shaped slot 2, and a countersunk hole is provided at the locking end of the arc-shaped T-shaped slot 2.

[0030] The ring seat 3 has locking pins 4 slidably nested on both its left and right sides. The upper part of the locking pin 4 is slidably nested in the corresponding arc-shaped T-shaped groove 2. The bottom of the ring seat 3 is connected to a cylinder 5 corresponding to the position of the locking pin 4. The bottom end of the cylinder 5 is connected to a hydraulic cylinder 6. The telescopic end of the hydraulic cylinder 6 is connected to a locking rod 7, which is connected to the locking pin 4.

[0031] The lower part of the locking pin 4 is cylindrical, and the upper part of the locking pin 4 has a T-shaped cross-section when viewed from the front. The upper part of the locking pin 4 matches the pin insertion hole, ensuring that the locking pin 4 can be inserted into the arc-shaped T-shaped groove 2 through the pin insertion hole. The T-shaped head of the locking pin 4 matches the countersunk hole, which increases the contact area between the locking pin 4 and the arc-shaped T-shaped groove 2 when locking, thereby improving the stability and reliability of locking.

[0032] The ring seat 3 is fixed with a guide positioning bushing 8 at the position corresponding to the locking pin 4. The lower part of the locking pin 4 is slidably nested in the guide positioning bushing 8, and the guide positioning bushing 8 provides precise guidance for the movement of the locking pin 4.

[0033] The locking lever 7 is nested inside the cylinder 5, saving space.

[0034] The ring seat 3 is equipped with a positioning platform to ensure accurate alignment between the lower clamping plate 1 and the ring seat 3, thereby improving the accuracy and efficiency of assembly.

[0035] An axial sealing ring 9 is provided between the lower clamping plate 1 and the ring seat 3 to effectively prevent leakage of internal pressure medium and improve safety. There are two axial sealing rings 9, providing double sealing protection and improving sealing performance and safety.

[0036] In this utility model, during installation, the lower clamping plate 1 is aligned with the positioning platform of the ring seat 3, and the pin insertion hole of the arc-shaped T-groove 2 at the bottom of the lower clamping plate 1 is aligned with the head of the locking pin 4 on the ring seat 3, so that the head of the locking pin 4 can be inserted into the pin insertion hole. Then, the lower clamping plate 1 is rotated so that the locking pin 4 enters the locking end of the arc-shaped T-groove 2. Then, the hydraulic cylinder 6 works to pull the locking pin 4 through the locking rod 8. The guide positioning bushing 8 moves and guides the locking pin 4 to prevent the locking pin 4 from deviating. The locking end of the arc-shaped T-groove 2 is provided with a countersunk hole, and the head of the locking pin 4 is nested in the countersunk hole, which can prevent the lower clamping plate 1 from rotating and loosening. After the operation is completed, the locking state is achieved.

[0037] During disassembly, the hydraulic cylinder 6 works by pushing the locking pin 4 through the locking lever 8, causing the head of the locking pin 4 to exit the countersunk hole at the locking end. Then, the lower chuck 1 is rotated in the opposite direction, causing the locking pin 4 to move from the locking end of the arc-shaped T-slot 2 to the unlocking end of the arc-shaped T-slot 2, thus achieving the unlocked state.

[0038] The locking and unlocking ends of the arc-shaped T-slot 2, combined with the locking pin 4, hydraulic cylinder 6, locking lever 7, and other structures, enable quick locking and unlocking of the capsule, thus greatly shortening the time required for capsule replacement. The entire locking and unlocking process mainly relies on the drive of the hydraulic cylinder 6. Operators only need to control the movement of the hydraulic cylinder 6 to complete the capsule replacement. The operation is simple and convenient, reducing the difficulty and labor intensity of operation, and further improving the efficiency of capsule replacement.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
