Description

Technical Field

[0001] This utility model belongs to the field of tire technology, specifically relating to an adjustable oblique puncture exhaust needle. Background Technology

[0002] In the manufacturing process of all-steel radial tires, in order to prevent air bubbles from forming between the tire carcass and the tread or sidewall rubber, the tire carcass surface is usually punctured manually at an angle (about 45°) using an air venting needle to vent the air.

[0003] Existing venting needles have the following defects: 1. The piercing depth lacks effective control. Slight carelessness in operation can easily pierce the cord layer, causing steel wire breakage or exposure, affecting tire quality; 2. The tool structure is relatively simple and generally lacks depth limit protection design; 3. The venting effect is unstable, and problems such as tire bulges, bubbles, and poor quality can easily occur due to incomplete venting or tire damage; In actual production, a small batch of steel wire punctures have occurred in the all-steel plant; Analysis results show that the problem occurred when puncturing and venting during the green tire stage, due to excessive piercing depth, which accidentally damaged the cord layer. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an adjustable oblique puncture venting needle to solve the quality risk problem caused by the lack of depth control in existing venting tools. Especially for the green tire stage of all-steel radial tires, it avoids excessive puncture and damage to the cord layer, improving the safety and standardization of venting operations.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] like Figures 1-3 An adjustable oblique puncture and exhaust needle includes a needle body 1, with a puncture needle head 2 at one end of the needle body 1. The needle body 1 includes a first mating section 11 near the puncture needle head 2 and a second mating section 12 away from the puncture needle head 2. A depth limiting ring 4 is slidably connected to the outer periphery of the first mating section 11, and a handle 3 is connected to the outer periphery of the second mating section 12. Scale lines are provided on the surface of the needle body 1.

[0024] The puncture needle 2 includes a needle tip section 21 and a first connecting section 22. One end of the first connecting section 22 is connected to the needle tip section 21, and the other end of the first connecting section 22 is connected to the first mating section 11. The needle tip section 21 has a conical structure with a taper of 20-40°. A sliding groove 13 is provided on the outer periphery of the first mating section 11 along the length direction. The depth limiting ring 4 is slidably connected to the first mating section 11 through the sliding groove 13.

[0025] The first mating section 11 has an external thread on its outer circumference, and the depth limiting ring 4 has internal threads at positions corresponding to the external thread. The first mating section 11 and the depth limiting ring 4 are slidably adjusted through the sliding groove 13 and locked by a threaded connection. The handle 3 includes a second connecting section 31 and an arc section 32. The second mating section 12 has an external thread on its outer circumference, and the second connecting section 31 has internal threads at positions corresponding to the external thread. The second mating section 12 and the second connecting section 31 are threadedly connected. The sliding groove 13 has a length of 15 mm and a groove depth of 1.5 mm.

[0026] The puncture needle 2 is made of steel, and the needle tip 21 is designed in a conical shape to reduce the risk of damage to the cord layer. The depth limiting ring 4 is installed on the outside of the needle body 1 and has a sliding adjustment function. It is locked with the threaded structure, making adjustment convenient and secure. The handle 3 is threaded to the needle body 1 and adopts an ergonomic design to enhance grip comfort and improve operational stability. The surface of the needle body 1 is laser-etched to assist the operator in adjusting the puncture depth according to the tire specifications, ensuring standardized operation.

[0027] The operation process of this utility model is as follows: When in use, the operator adjusts the depth limiting ring to the designated position and locks it in advance according to the tire process requirements. During the puncture process, the tool punctures the surface of the green tire at an angle of about 45°. When the depth limiting ring contacts the tire surface, it effectively prevents the puncture depth from exceeding the set value, thereby ensuring that the gas is discharged smoothly and will not damage the steel cord layer. The venting needle has a simple structure and is easy to operate. It is suitable for batch and rapid operation in the workshop, reduces human error, and improves the consistency of venting quality.
