Description

Technical Field

[0001] The utility model relates to the technical field of two-device components, in particular to a pipe mouth tooling of a two-device component for aluminum which can prevent overburning. Background Art

[0002] In the heat treatment process of aluminum two-device components on the market, temperature control is extremely important. Once a certain temperature threshold is exceeded, the aluminum two-device components will be overburned, which will seriously affect the physical properties of the material and even cause the entire part to be scrapped. The structural design of the tooling in the prior art does not fully consider the problems of heat dissipation and thermal expansion, resulting in the ineffective dissipation of heat, or the expansion of the pipe nozzle tooling causing jamming and other problems.

[0003] Therefore, in this application, the heat dissipation hole design of the pipe nozzle tooling is adopted to control the temperature, facilitate heat dissipation, and avoid overburning. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a pipe mouth tooling for aluminum two-device components to prevent overburning, which is mainly used for the automatic welding production of aluminum tube two-device components, and uses the tooling to protect the component pipe mouth (bell mouth) to avoid overburning.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an anti-overburning aluminum two-device assembly pipe mouth tooling, including a pipe mouth tooling, the pipe mouth tooling includes a tooling head and a tooling straight arm, the tooling head is connected to the tooling straight arm, the center of the tooling head is provided with a head through hole, the center of the tooling straight arm is provided with a straight arm through hole, the head through hole is connected to the straight arm through hole, the tooling head is in an open state, and the tooling head is connected to the aluminum tube.

[0006] As a further improvement of the utility model: the straight arm of the tooling is connected to an aluminum tube, the aluminum tube is made of aluminum alloy, the aluminum tube is formed by extrusion technology, and the cross-sectional shape and specification of the aluminum tube are produced through the shape and size of the mold. The surface treatment of the aluminum tube is anodized or sprayed with a coating.

[0007] As a further improvement of the present invention: the top of the aluminum tube is connected to the top inner part of the tool head by contact, the center coaxiality of the aluminum tube and the pipe mouth tool is consistent, and error-free docking is ensured.

[0008] As a further improvement of the utility model: the top of the aluminum tube and the lower end of the aluminum tube have arc-shaped upper chamfers, and the upper chamfers are streamlined and fit with the aluminum tube.

[0009] As a further improvement of the present invention: the diameter and shape size of the head through hole and the straight arm through hole are the same and they are connected.

[0010] As a further improvement of the utility model: the top of the tool head has arc-shaped lower rounded corners around it.

[0011] As a further improvement of the present invention: the tool head is in the shape of an umbrella-shaped cap, the top of the tool head is in the shape of a semi-dome, and the four sides of the tool head extend downward to form an edge.

[0012] As a further improvement of the utility model: the nozzle tooling is connected to a special box, and the special box is sent to the welding machine through a conveyor belt.

[0013] As a further improvement of the utility model: the nozzle tooling is suitable for aluminum two-device components with a size of φ7.

[0014] As a further improvement of the utility model: the aluminum two-device assembly is connected to the automatic flame welding equipment.

[0015] As a further improvement of the present invention: the head through hole is located at the top of the tooling, while the straight arm through hole is the part extending along the tooling.

[0016] As a further improvement of the present invention: the top of the aluminum tube and the aluminum tube have an arc-shaped upper rounded corner, which means that the edge of the top of the aluminum tube has been carefully polished and bent to form an elegant curve, which not only makes the appearance of the aluminum tube more smooth, but also increases the comfort of touch. Such rounded corner treatment can effectively avoid accidental scratches and damages caused by right angles or sharp angles, thereby improving the safety performance of the product.

[0017] As a further improvement of the present invention, the top of the aluminum tube is precisely processed to form a shape that can perfectly match the inner wall of the top of the tooling, and then physically inserted therein. Since there is no dielectric layer of any form between the two, direct contact with extremely high precision can be achieved.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The melting point of the aluminum tube raw material used in the utility model and the melting point of the aluminum elbow welding ring inserted into the tube mouth are both around 600℃. The temperature regulation of the welding machine flame is limited. When the aluminum component passes through the welding machine, there will be a bare tube mouth without an elbow. The flame will melt the tube mouth and cause the component to be scrapped. The current tooling is inserted into the tube mouth during production, and the tooling head can cover the tube mouth in all directions to avoid direct flame burning, effectively solving the burning problem.

[0020] Aluminum alloy tooling has similar physical and chemical properties to aluminum tubes and aluminum elbows. When the two come into contact, they can achieve efficient heat transfer and reduce the temperature of the aluminum tube itself. At the same time, the tooling head can completely cover the tube mouth to avoid direct burning by the welding flame, further reducing the risk of melting at the tube mouth and the cost of scrapping.

[0021] The use of this tooling can significantly reduce the risk of overburning and ensure production safety. At the same time, it can also meet the processing needs of aluminum materials of various specifications and shapes, and has strong versatility and adaptability.

[0022] The head through hole and straight arm through hole ensure that the aluminum parts are always in the optimal processing temperature range, making it suitable for aluminum two-device components of various specifications and convenient for operators to quickly replace and maintain.

[0042] The working principle of this utility model:

[0043] The utility model adopts aluminum alloy with similar physical and chemical properties to aluminum to manufacture the protection tooling, so as to ensure smooth heat conduction between the two. The aluminum alloy protection tooling is inserted into the pipe mouth of the aluminum tube two-device component, and heat can be transferred to the protection tooling in a high temperature state. The head of the aluminum alloy protection tooling is designed as an "umbrella-shaped" cap, which can achieve full protection of the component pipe mouth. The protection tooling itself is designed with a head through hole of a cylindrical channel and a straight arm through hole to dissipate heat, so as to avoid deformation and breakage caused by excessive heat.

[0044] Implementation case 1:

[0045] like Figure 1-2 The shown embodiment is a pipe nozzle tooling for an aluminum two-device assembly that prevents overburning, including a pipe nozzle tooling, wherein the pipe nozzle tooling includes a tooling head 1 and a tooling straight arm 2, wherein the tooling head 1 is connected to the tooling straight arm 2, a head through hole 3 is provided at the center of the tooling head 1, a straight arm through hole 4 is provided at the center of the tooling straight arm 2, the head through hole 3 is connected to the straight arm through hole 4, the tooling head 1 is in an open state, and the tooling head 1 is connected to an aluminum tube 5.

[0046] The straight arm 2 of the tooling is connected to the aluminum tube 5, and the aluminum tube 5 is made of aluminum alloy. The aluminum tube 5 is produced by extrusion molding technology through the shape and size of the mold to produce the aluminum tube 5 with a cross-sectional shape and specification. The surface treatment of the aluminum tube 5 is anodized or sprayed with a coating. The top of the aluminum tube 5 is connected to the top of the tooling head 1 by contact. The center coaxiality of the aluminum tube 5 and the nozzle tooling is consistent, and error-free docking is ensured. The top of the aluminum tube 5 and the lower end of the aluminum tube 5 have an arc-shaped upper chamfer, and the upper chamfer adopts flow The line shape fits with the aluminum tube 5, the diameter and shape size of the head through hole 3 and the straight arm through hole 4 are the same and connected, the top of the tool head 1 has an arc-shaped lower chamfered corner, the shape of the tool head 1 is an umbrella cap, the top of the tool head 1 is semi-dome-shaped, and the four sides of the tool head 1 extend downward to form an edge, the pipe mouth tool is connected to a special box, and the special box is sent to the welding machine through a conveyor belt. The pipe mouth tool is suitable for a φ7-sized aluminum two-device component, and the aluminum two-device component is connected to an automatic flame welding equipment.

[0047] This embodiment uses an aluminum alloy pipe nozzle tooling, and the middle part of the pipe nozzle tooling is designed with a cylindrical head through hole 3 and a straight arm through hole 4 to facilitate heat dissipation. The tooling head 1 is an "umbrella-shaped" cap to achieve full protection of the aluminum two-device assembly pipe nozzle to avoid burning.

[0048] Before the aluminum two-device assembly enters the automatic flame welding equipment, the straight arm 2 of the nozzle fixture is inserted into the aluminum tube 5, and the nozzle fixture is assembled in place when it contacts the top of the fixture head 1. When passing through the welding flame, the flame at the bare tube mouth will be blocked by the "umbrella-shaped" cap of the nozzle fixture, and the heat of the overall tube body will be transferred to the nozzle fixture to dissipate heat through the head through hole 3 and the straight arm through hole 4, which can effectively solve the burning problem. When the welding is offline, the employee inverts the assembly, causing the nozzle fixture to fall into a special box and be sent to the front of the welding machine for recycling.

[0049] The aluminum alloy nozzle tooling has similar physical and chemical properties to aluminum, ensuring smooth heat conduction between the two. The size design is suitable for all Φ7 aluminum two-device components and has strong versatility. The protective tooling is of appropriate size, convenient for employees to take and place, and meets practicality. The welding line is recycled before and after, which is economical and affordable.

[0050] Implementation case 2:

[0051] In this embodiment, Figure 1-2 The shown embodiment is a pipe nozzle tooling for a two-device assembly for aluminum that prevents overburning, and the technical means are consistent with the pipe nozzle tooling for a two-device assembly in implementation case one.

[0052] The structural design of this embodiment is scientific and reasonable, and is easy for the operator to quickly install and disassemble, which greatly improves the working efficiency; secondly, the nozzle tooling is extremely durable and can maintain stable performance even under long-term and high-intensity working conditions, thereby reducing maintenance costs; thirdly, due to its heat dissipation capacity, it can effectively reduce the scrap rate caused by improper temperature control during the processing process and improve product quality.

[0053] The raw materials of air conditioner parts and components are gradually replaced by aluminum instead of copper. The price of aluminum tubes is about half of that of copper tubes, and a dense aluminum oxide film can be formed on the surface of aluminum, which can effectively prevent atmospheric corrosion and extend the service life of manufactured products. Among them, aluminum two-device components have become a subsequent promotion trend. In combination with actual production, studying the characteristics of aluminum and its accompanying products has become an important task.

[0054] The raw material of the aluminum tube 5 has a melting point of about 600°C. The aluminum two-device assembly is made of multiple long U-tubes (bent aluminum tubes) inserted into the fins to complete the tube expansion. According to the system circuit, an aluminum elbow (the melting point of its welding ring is about 600°C) is installed at the tube mouth. After passing through the welding machine, the welding ring melts and cools to achieve the connection with the parent material.

[0055] Implementation case three:

[0056] In this embodiment, Figure 1-2 The shown embodiment is a pipe nozzle tooling for a two-device assembly for aluminum that prevents overburning, and the technical means are consistent with the pipe nozzle tooling for a two-device assembly in implementation case one.

[0057] The design of the nozzle fixture in this embodiment takes into account the fact that aluminum products are prone to overburning in high temperature environments, so heat dissipation holes such as the head through hole 3 and the straight arm through hole 4 are specially added to the structure to optimize the heat dissipation efficiency. Through these cleverly arranged heat dissipation holes, the nozzle fixture can quickly discharge the heat generated during the processing, effectively reduce the temperature at the nozzle of the component, and thus reduce the risk of material deformation or performance degradation caused by excessive temperature.

[0058] The nozzle fixture is made of high-quality heat-resistant materials to ensure durability and stability under extreme working conditions. The nozzle fixture has a composite cavity designed inside to accurately accommodate and fix various types of aluminum nozzles to ensure centering and consistency during processing. At the same time, this structure also gives the fixture good mechanical strength, able to withstand continuous and repeated loads, and extend its service life.

[0059] In terms of safety, the nozzle tooling is also equipped with a series of sensing devices for real-time monitoring of temperature changes in components. Once an abnormal temperature rise is detected, the system will immediately trigger an alarm and automatically adjust the heat dissipation mechanism to prevent potential overheating problems. In addition, the nozzle tooling's operating interface design is intuitive and easy to understand, and operators can easily master the various parameter settings to ensure the smooth progress of the processing process. The use of this nozzle tooling not only improves production efficiency, but also greatly improves product quality and reliability. After actual application testing, the tooling can not only improve the heat dissipation effect, but also ensure that the processing accuracy is not affected. This nozzle tooling for two-device components for aluminum with heat dissipation holes to prevent overburning has its efficient heat dissipation capacity, precise positioning function and reliable safety protection. It not only optimizes the production process and reduces production costs, but also ensures product quality, showing excellent practical value and economic benefits.
