Embodiment 1

[0045] refer to figure 1 and Figure 5 , a welding device in a semi-enclosed space, comprising a welding room 1, wherein the welding room 1 is a 匚-shaped stainless steel building, in order to facilitate soldering in the welding room 1, a welding platform for soldering is fixed in the welding room 1 10. At the same time, a seat can also be configured in the welding room 1, and the operator can sit on the seat and perform soldering on the top of the welding platform 10; because in the soldering process, the solder used in the soldering contains clamps and auxiliary Flux, harmful substances will volatilize when the welding rod melts. In order not to affect the health of the welding operator, a first drainage cover 11 is slid and connected in the vertical direction above the welding platform 10 inside the welding room 1. The first drainage cover 11 is set in a form that can be adjusted up and down so that the area and range of air absorption can be adjusted, and at the same time,...

Embodiment 2

[0055] The difference from Example 1 is that the surface of the welding platform 10 is coated with an anti-fouling coating. Since the soldering is performed on the welding platform 10, it is inevitable that solder will fall on the welding platform 10 during soldering. In order to prevent the solder from adhering to the welding platform 10 and it is difficult to clean, a layer of antifouling coating is coated on the surface of the welding platform 10, so a method for preparing an antifouling coating is provided, which has the advantages of short preparation process and simple preparation. Advantages, wherein the preparation method of the antifouling coating on the surface of the welding platform 10 is as follows:

[0056] Take the following components by weight for later use: 42 parts of methyl methacrylate, 43 parts of polyethylene, 35 parts of polypropylene, 25 parts of fatty alcohol polyoxyethylene ether, 21 parts of alkylphenol polyoxyethylene ether, sodium acrylate 17 part...

Embodiment 3

[0062] The difference from Example 2 is the preparation of the antifouling coating on the surface of the welding platform 10, wherein the preparation method of the antifouling coating is as follows:

[0063] Take the following components by weight for later use: 43 parts of methyl methacrylate, 44 parts of polyethylene, 36 parts of polypropylene, 26 parts of fatty alcohol polyoxyethylene ether, 21 parts of alkylphenol polyoxyethylene ether, sodium acrylate 17 parts, 11 parts of methylisothiazolinone;

[0064] S1. Preparation of antifouling coating pre-preparation solution: mix methyl methacrylate, polyethylene and polypropylene evenly and add to the reaction kettle, heat the temperature in the reaction kettle to 185°C and keep it warm for 20 minutes to obtain an antifouling coating pre-preparation solution;

[0065] S2. Preparation of antifouling coating solution: After cooling the antifouling coating pre-preparation solution obtained in S1 to 85°C, add fatty alcohol polyoxyeth...

Abstract

The invention discloses a welding device with a semi-closed space, and belongs to the field of welding. The technical scheme of the welding device with the semi-closed space is characterized by comprising a welding room, wherein the welding room is a stainless steel building with a right-angled C shape; a welding platform used for tin welding is fixed in the welding room, a first drainage cover isslidably connected to the upper portion, located inside the welding room, of the welding platform along the vertical direction, and one end of the first drainage cover is in communication with a corrugated pipe; and the top of the welding room is also fixedly provided with a first suction fan, the other end of the corrugated pipe penetrates through the top of the welding room to be in communication with an air inlet end of the first suction fan, and the air outlet end of the first suction fan is further in communication with a first pipeline. According to the welding device with the semi-closed space, the polluted air generated in the tin welding process can be drawn out of the welding room, the range of air sucked out of the welding room can be adjusted through adjusting the height of the drainage cover, and the health safety of an operator is protected.

Description

technical field [0001] The invention relates to the field of welding, more specifically, it relates to a semi-enclosed space welding device. Background technique [0002] Welding, also known as welding and welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. There are many forms of welding to achieve the purpose of joining. The most widely used in soldering is soldering. [0003] Soldering is a welding method that uses low melting point metal solder to heat and melt, penetrate and fill the gap at the joint of metal parts. Because the solder is often a tin-based alloy, it is called tin soldering, and a soldering iron is often used as a heating tool. Soldering is widely used in the electronics industry. [0004] When manually soldering, there will be a large smell, and the common soldering rods all contain lead and flux, and volatiles will volatilize dur...
