Abstract
Description
Technical Field
[0001] The invention relates to the field of new energy vehicles, in particular to a sealing gasket punch for a three-way water valve of a new energy vehicle. Background Art
[0002] The main power source of new energy vehicles is electricity, which has lower electricity costs than traditional fuel vehicles. New energy vehicles have almost zero emissions during operation, and do not produce harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides, which greatly reduces air pollution. In particular, pure electric vehicles have more significant environmental protection effects. Plug-in hybrid vehicles can also reduce tail gas emissions in pure electric mode, which has a positive contribution to improving air quality. The power system of new energy vehicles is relatively simple, without complex engines and transmissions, which reduces the wear and replacement frequency of parts. Maintenance items are mainly concentrated on the inspection and maintenance of batteries, motors and electronic control systems, with longer maintenance cycles and lower costs. Three-way valve gasket products are composed of EPDM rubber and PTFE skeletons. Three combinations are installed in the water valve of the thermal management system of new energy vehicles. They are widely used to control the dynamic sealing of the switch of the water valve. They are the core components of the thermal management system of new energy vehicles. There are many types of products of the same type and the market prospects are broad. Water valve gaskets can prevent liquid leakage. The main function of water valve gaskets is to prevent water and other liquids from penetrating into the water valve, protect key components from moisture, ensure the normal operation of the system and extend the service life of the equipment. Gaskets made of high-quality materials, such as silicone, are soft and durable, can maintain their sealing effect during long-term use, and are not easy to age or deform, thus ensuring the stability and reliability of the system. The installation process of the gasket is relatively simple, usually just placing it between the water valve and the pipe and then fixing it. This convenient installation method reduces installation time and cost. Gaskets can adapt to different connection surfaces, especially those with good elasticity and plasticity, which can better fit uneven surfaces and provide better sealing effects.
[0003] The traditional structure has poor production stability, low production efficiency and low product qualification rate. With the increasing popularity of new energy vehicles in recent years, the existing traditional manual punching has poor stability, which is easy to cause product damage and low qualification rate; the traditional manual punching speed is slow and the production efficiency is low. The state of the traditional manual punching flash cannot be adjusted and the qualification rate is low. The demand for three-way water valve gaskets in thermal management systems is also increasing, which undoubtedly puts forward higher production efficiency requirements and product quality challenges for the manufacturing industry.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", and "connected" should be understood in a broad sense; for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, or an electrical connection, a direct connection, or an indirect connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] The main function of the automotive three-way water valve gasket is to prevent water and other liquids from penetrating into the interior of the car and protect key components from moisture. Specifically, the automotive three-way water valve gasket plays a sealing role at the interface of the three-way water valve, ensuring that the water valve can maintain a sealed state under various working conditions to prevent liquid leakage. In addition, the material selection of the gasket is also very important. Usually non-metallic materials such as rubber, polyurethane, polytetrafluoroethylene, etc. are used. These materials have good elasticity and corrosion resistance and can adapt to different working environments.
[0026] See also Figure 1-4A three-way water valve sealing gasket punch for new energy vehicles, comprising a cover plate 1, a support plate 3, a punch 4, a pad 5 and a spring 6; a support plate 3 is provided above the pad 5, a three-way water valve sealing gasket 2 is laid on the upper surface of the support plate 3, a punch 4 is provided on the pad 5, a spring 6 is provided between the punch 4 and the pad 5, and the cover plate 1 is arranged above the support plate 3.
[0027] The support plate 3 can reduce the pressure during the stamping process and prevent the die from being damaged due to excessive pressure. It can absorb part of the impact force, protect the die and extend its service life. The support plate can ensure the accurate positioning of the stamped product and reduce product deformation and burrs. If the support plate is not selected properly, the product may become burred, rough, or even damaged. The material selection of the support plate has an important influence on the stamping effect. Commonly used support plate materials include white EVA and blue high-elastic cotton. For special materials such as PP cardboard, a gray sponge pad knife can be used because it is softer and can reduce creases and scratches on the four corners of the product.
[0028] Use the original inner hole punch to remove the inner hole flash, align the inner hole of the product with the circular punch, and apply pressure to the cover plate; align the product after punching the inner hole with the cylinder on the support plate and position it according to the shape; fix the position of the cover plate with the guide column; apply pressure downward, the spring contracts, the punch contacts the cover plate, and the punching is completed.
[0029] A groove is provided on the lower surface of the cover plate 1, and the groove is arranged directly above the support plate 3. The design of the cover plate 1 enables the mold to better control the shape and size of the gasket during the injection molding process, ensuring the consistency and quality of each gasket. This can not only reduce the scrap rate, but also improve production efficiency. The design of the cover plate 1 can ensure that the gasket fully fills every corner of the mold during the injection molding process, avoiding the generation of bubbles and voids, thereby improving the sealing performance and reducing the risk of water leakage. Reasonable design of the cover plate 1 can reduce the wear and deformation of the mold during use, extend the service life of the mold, and reduce maintenance costs. By precisely controlling the injection molding process, material waste and energy consumption are reduced, thereby optimizing the cost structure and improving the overall economic benefits.
[0030] The size of the groove is larger than that of the support plate 3. When working, the support plate 3 can be easily pressed into the groove on the lower surface of the cover plate 1, which is convenient for the use of the device and ensures safety. The size and shape of the groove directly affect the compression and stretching of the three-way water valve gasket, and thus affect its sealing performance and service life. The common groove shape is a rectangular groove. The design needs to ensure that the three-way water valve gasket can freely expand and contract in the groove while maintaining a good sealing effect.
[0031] Guide post holes 8 are provided on the cover plate 1 and the pad 5, and guide posts are provided in the guide post holes 8 to ensure the positioning and alignment of the cover plate 1 and the pad 5, increase safety, facilitate the subsequent punching of the three-way water valve sealing gasket 2, and facilitate the use of the device.
[0032] There are three groups of guide post holes 8, which are respectively arranged at three of the four corners of the cover plate 1 or the pad 5, which is conducive to positioning and alignment, increases safety, facilitates the subsequent punching of the three-way water valve sealing gasket 2, and facilitates the use of the device. The guide post forms a positioning hole in the mold to ensure that the mold has an accurate positioning function and ensures the stability and precision of the mold when in use. The guide post positions the internal parts of the mold with high precision, ensures that the upper and lower molds are aligned in the correct position, and improves production efficiency and product quality. The guide post balances the force on the mold, avoids deviation or deformation of the mold due to deformation, looseness and other reasons of the internal parts, and ensures that the mold will not deform during use. The guide post can extend the service life of the mold, reduce damage and wear of the internal structural parts of the mold, and protect the internal parts of the mold.
[0033] A spring hole is provided inside the pad 5, and the spring 6 is arranged in the spring hole to ensure the safety of the device when it is working and facilitate the use of the device. When the sealing pad punch is working, the main function of the pad is to prevent the punch from pressing a pit on the upper die seat during the punching process, thereby ensuring that the mold will not loosen in the axial direction. In addition, the pad is reasonably designed and easy to install, which can significantly extend the service life of the tool, reduce the replacement frequency and cost, and at the same time improve the working efficiency and processing quality of the equipment, and ensure the continuity and stability of production. The spring provides pressure by deforming under force, so that sufficient pressure is formed between the sealing surfaces, thereby achieving a sealing effect. During the working process of the mechanical seal, due to the presence of a small gap between the sealing surfaces, the gap can be filled by the pressure provided by the spring, thereby achieving sealing. During the working process of the mechanical seal, due to the influence of factors such as temperature and pressure, the contact state between the sealing surfaces may change. The presence of the spring can keep the sealing surface in a certain contact state at all times, thereby ensuring the sealing effect. During the working process of the mechanical seal, due to the influence of factors such as the impact and vibration of the fluid, the sealing surface may be subjected to a large impact. The presence of the spring can play a buffering role and reduce the impact and vibration of the sealing surface. The spring can also make the end faces of the friction pair fit closely, and play a compensatory role after the end faces of the friction pair are worn, ensuring the close fit of the sealing surface.
[0034] A plurality of sets of fixing columns 7 are provided on the pad 5, and the support plate 3 is connected to the pad 5 through the fixing columns 7, which is conducive to the subsequent punching of the three-way water valve gasket 2 and convenient for the use of the device. The punching knife 4 is a circular punching knife, which is convenient for punching the inner hole of the three-way water valve gasket 2, increases safety, and facilitates the use of the device. When the gasket punching knife is working, the main function of the punching knife is to cut and shape the gasket material. The punching knife makes the blade contact with the material and apply pressure through high-speed rotation or reciprocating motion, thereby cutting or carving out the desired shape. The advantages of the punching knife include fast cutting speed, high precision, easy operation, and suitable for large-scale production and processing. The punching knife is usually composed of a handle and a blade, and the blade can be replaced as needed to meet different cutting or carving requirements. Its working principle is to make the blade contact with the material and apply pressure through high-speed rotation or reciprocating motion, thereby cutting or carving out the desired shape.
[0035] The punching knife 4 and the backing plate 5 are detachably connected, so that different components of the punching knife 4 can be easily replaced during operation. There are three groups of punching knives 4, and the blade spacing of each punching knife 4 differs by 0.1 mm. One of the three groups of punching knives 4 is installed on the backing plate 5. The punching knife rotates or reciprocates at high speed, so that the blade contacts the material and applies pressure, thereby cutting or engraving the desired shape. The advantages of the punching knife include fast cutting speed, high precision, and simple operation, and it is suitable for large-scale production and processing.
[0036] The present invention uses the original inner hole punch to remove the inner hole flash. The inner hole of the product is aligned with the circular punch, and pressure is applied to the cover plate; the product after punching the inner hole is aligned with the cylinder on the support plate and positioned in accordance with the shape; the position of the cover plate is fixed by the guide column; pressure is applied downward, the spring contracts, the punch contacts the cover plate, and the punching is completed. In addition, 3 replaceable punch assemblies are processed at the same time, and the distance between each blade is 0.1mm. In actual production, the punch assembly can be replaced according to the current flash state, so as to adjust the flash size state, ensure the flash size is qualified, and avoid accidental damage to the product.
[0037] The quality of the product is completely determined by the trimming technique of the puncher in the traditional manual trimming method, which is extremely unstable and easily causes damage to the product, and the finished product quality is poor. The quality of the product punched by the punching knife of the present invention is significantly improved. The production speed of the traditional manual trimming method is slow. It takes an average of 50-70 seconds for a skilled worker to trim a product. After using the punching knife of the present invention, it only takes 20-25 seconds, and the production efficiency is significantly improved.
[0038] The punching knife of the present invention can timely adjust the flash state according to the actual production situation, ensure that the flash size is qualified and avoid accidental damage to the product, and the qualified rate is significantly improved. At the same time, three replaceable punching knife components are processed, and the spacing between each blade is 0.1mm. In actual production, the punching knife components can be replaced according to the current flash state to adjust the flash size state, ensure that the flash size is qualified and avoid accidental damage to the product. Improve production efficiency, ensure sealing performance and reduce manufacturing costs. The design of the punching knife tool makes the stamping process more efficient, can quickly and accurately complete the stamping work of the sealing gasket, reduce the time and labor intensity of manual operation, and thus improve the overall production efficiency. Through the precise stamping process, it can be ensured that the size and shape of the sealing gasket meet the design requirements, thereby ensuring its sealing performance in the three-way water valve, reducing the possibility of leakage, and extending the service life of the water valve. The automated and precise stamping process reduces material waste, while improving production efficiency, thereby reducing manufacturing costs. In addition, the reusability of the punching knife tool also further reduces long-term production costs.
