Description

Technical Field

[0001] The present invention relates to the technical field of valve processing equipment, and in particular, to a one-time welding and forming equipment for valve processing. Background Art

[0002] In the precise and complex process of valve processing, the welding process occupies a crucial and irreplaceable core position, closely connecting all aspects of valve production. The quality of its processing accurately measures the overall performance of the valve. High-quality welding can ensure seamless flow of the internal medium of the valve. In terms of durability, firm and uniform welding points are like strong fortresses, which can effectively resist the erosion of various pressure and temperature changes during long-term use and extend the service life of the valve. In terms of the stability of various performance indicators, the welding quality plays a decisive role, ensuring the stable operation of the valve consistently under different working conditions and providing a solid guarantee for the smooth operation of the entire industrial system. Therefore, there is a particular need for a one-time welding and forming equipment for valve processing.

[0003] However, in the traditional valve processing process of existing valve processing and welding and forming equipment, multiple welding operations are often required. Each welding operation requires professional workers to spend a lot of time and carefully operate the welding equipment, which greatly consumes labor costs. Moreover, during multiple welding processes, thermal stress will continuously accumulate. Most valve components are made of metal. After repeated heating, the internal structure of the metal will change, resulting in component deformation, seriously affecting the overall quality of the valve, thereby reducing the sealing performance of the valve. At the same time, multiple welding will also bring many hidden dangers to the weld, easily generating defects such as pores and cracks, which will deteriorate over time, greatly reducing the service life of the valve, and even causing safety accidents at critical moments, endangering production and personnel safety.

[0004] In the current existing technology, Chinese Patent Publication No.: CN207239388U discloses a valve automatic welding device. In this valve automatic welding device, a positioning device, a welding device, and an electrical control device are provided on the workbench. The positioning device includes a cylinder half-shell positioning die adapted to the workpiece, a top rod, an adjusting rod for positioning the top rod, a top rod cylinder for controlling the up-and-down reciprocating movement of the top rod on the adjusting rod, and a speed-regulating motor for driving the rotation of the cylinder half-shell positioning die and capable of adjusting the speed. The welding device includes a welding torch, a welding torch fixture, and an adjusting assembly provided on the workbench for adjusting the welding point position of the welding torch. The adjusting assembly includes a welding torch fixture guide rod and a welding torch extending cylinder for controlling the extending and retracting reciprocating movement of the welding torch. However, when welding the valve, due to the special shape of the valve itself, the path length and shape of the valve to be welded are not fixed, and multiple weldings are required to complete the welding of the valve. Moreover, multiple weldings of the valve are likely to cause discontinuity between the two welding parts, and there may be welding gaps, resulting in incomplete welding.

[0005] Therefore, in view of the above problems, a one-time welding and forming device for valve processing is proposed. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The one-time welding and forming equipment for valve processing of the present invention realizes the one-time welding and forming of valves through the coordinated operation of the positioning, clamping and replacement assembly and the lifting and rotating welding assembly. The motor in the positioning, clamping and replacement assembly drives the rotating seat, which can quickly adjust the position of the valve to be welded. Cooperating with multiple groups of moving columns, sliding blocks and adapted slide rail structures, it can accurately position and clamp valves of different specifications, reducing the clamping time. The lifting and rotating welding assembly, with the combination of an electric cylinder and a cylinder, can flexibly control the lifting, rotation and movement of the welding head, and quickly plan and execute the welding path according to the welding requirements of the valve. Compared with the traditional multiple welding operations, each welding requires re-clamping and adjusting the equipment parameters, which greatly shortens the processing cycle of a single valve. In large-scale production scenarios, it can effectively improve production capacity and meet the large market demand for valves; 2. The one - time welding and forming equipment for valve processing of the present invention can precisely control welding parameters such as welding speed, current, voltage, etc. by setting up the lifting and rotating welding assembly, ensuring uniform and firm welds. The stable welding environment and precise operation greatly reduce the probability of welding defects. The high - quality welds effectively improve the sealing performance of the valve, enabling it to better resist medium erosion during long - term use, extending the service life of the valve, reducing the risk of industrial system shutdown caused by valve failures, ensuring the continuity and stability of production. Due to the improvement of welding quality, the defective rate of valves decreases, avoiding waste of raw materials caused by rework or scrapping of defective products, comprehensively reducing production costs, and improving the economic benefits of the enterprise; 3. The one - time welding and forming equipment for valve processing of the present invention has a highly flexible design by setting up the positioning, clamping and replacement assembly. Components such as slide rails, sliding blocks and replaceable positioning plates, in cooperation with clamping columns, mortise grooves and connecting grooves of different specifications, can be quickly adjusted to meet the clamping requirements of valves of various shapes and sizes. This enables enterprises to avoid purchasing multiple welding equipment for different types of valves, reducing equipment procurement costs, improving equipment utilization rate, enhancing the competitiveness of enterprises in the valve processing market, and being able to better meet the diverse order requirements of customers. The protective cover can effectively block the strong light, sparks and spatter generated during welding, preventing damage to the eyes, skin, etc. of operators. Good protective measures can also reduce the diffusion of welding fumes and harmful gases in the working area, improving the working environment, protecting the physical health of operators, and helping enterprises build a safe and healthy production environment to promote sustainable development.

Then, through the cooperation of the connecting column 923 and the connecting slot 921, remove the second positioning plate 922. Install the selected positioning plate according to the corresponding structure, align the mortise groove 914 of the first positioning plate 916 with the mortise groove 914 on the outside of the first sliding block 911 and insert it.
