Description

Technical Field

[0001] This utility model belongs to the field of welding wire testing technology, specifically relating to an online diameter measuring device at the outlet of the sizing die for a gas shielded welding wire split line. Background Technology

[0002] In modern welding processes, gas-shielded welding wire is an important welding material, and the precise control of its diameter has a crucial impact on welding quality. During the production process, gas-shielded welding wire requires precise sizing using a sizing die to ensure that the wire diameter meets process requirements.

[0003] Traditional sizing dies have significant shortcomings. For example, Chinese patent CN211360334U discloses a sizing die in which the die core and die shell are designed as a single unit. When changing the die, this technical solution requires replacing the entire die, increasing the complexity and cost of replacement and leading to unnecessary material waste. Furthermore, the sizing die in this solution lacks online monitoring of the welding wire diameter, making it impossible to obtain real-time data on the welding wire diameter, thus hindering timely and effective control and adjustment of welding quality. Utility Model Content

[0004] The purpose of this invention is to provide an online diameter measuring device at the outlet of the sizing die of a gas shielded welding wire split line, so as to solve the problems of high maintenance costs and lack of monitoring and control technology caused by the integrated mold core and mold shell of the existing sizing die.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An online diameter measuring device for the outlet of a sizing die for a gas shielded welding wire split line includes an upper die body and a lower die body used in conjunction with the upper die body. A detachable die core is installed inside both the upper and lower die bodies. A diameter measuring instrument for detecting the diameter of the gas shielded welding wire is installed on the side of the upper die body. A pressure sensor electrically connected to the diameter measuring instrument is installed on the inner wall of the die core.

[0007] As a further embodiment of this utility model, one end of the upper mold body and the lower mold body are rotatably connected by a connecting hinge, and the other end of the upper mold body and the lower mold body are fixedly connected by connecting bolts.

[0008] As a further embodiment of this utility model, a mounting slider for mounting the mold core is fixedly connected to the mold core, and a mounting groove for cooperating with the mounting slider is provided on the upper mold body.

[0009] As a further embodiment of this utility model, positioning components for fixing the mold core are installed on both the upper mold body and the lower mold body at positions corresponding to the mold core.

[0010] As a preferred embodiment of this utility model, the positioning component includes a threaded seat fixedly connected to the upper mold body, and the threaded seat is threaded with mounting bolts for fixing and installing the slider.

[0011] As a preferred embodiment of this utility model, the mounting slider is provided with mounting holes that match the mounting bolts at the corresponding positions.

[0012] As a further preferred embodiment of this utility model, two symmetrically arranged positioning sliders are fixedly connected to the mold core, and a positioning groove is provided on the upper mold body at the position corresponding to the positioning sliders to cooperate with the positioning sliders.

[0013] Compared with existing technologies, the online diameter measuring device at the outlet of the sizing die of the gas-shielded welding wire split line provided by this utility model has the following advantages:

[0014] 1. This device not only has online diameter measurement function and split design, making the control of welding wire diameter more precise and efficient, but also allows for timely adjustment of production process based on real-time monitoring data, reducing defect rate and improving production efficiency.

[0015] 2. This device achieves online monitoring of the welding wire diameter by incorporating a pressure sensor and a diameter gauge. When the welding wire passes through the sizing die, the pressure sensor detects the pressure exerted on the wire by the die in real time and transmits the data to an external computer. The diameter gauge directly measures the wire diameter and also transmits the result to the external computer. The computer performs comprehensive analysis of the two sets of data to determine whether the wire diameter meets the preset standard. This online diameter measurement function allows operators to monitor the wire diameter in real time, adjust production processes promptly, and ensure welding quality.

[0016] 3. The device features a separate design for the mold body and mold core, allowing for replacement of only the mold core when it is damaged, rather than replacing the entire mold. This significantly reduces operating costs and improves production efficiency. The separate design also makes mold maintenance and repair more convenient, extending the mold's lifespan. Furthermore, the online diameter measurement function and separate design enable more precise and efficient control of the welding wire diameter. Attached Figure Description

[0032] See appendix Figure 1-4 As shown in the figure, an online diameter measuring device for the outlet of the sizing die of a gas shielded welding wire split line according to an embodiment of the present invention includes an upper die body 1 and a lower die body 2 used in conjunction with the upper die body 1. A detachable die core 202 is installed inside both the upper die body 1 and the lower die body 2. A diameter measuring instrument 3 for detecting the diameter of the gas shielded welding wire is installed on the side of the upper die body 1. A pressure sensor 301 electrically connected to the diameter measuring instrument 3 is installed on the inner wall of the die core 202.

[0033] To facilitate the opening and closing of the mold, one end of the upper mold body 1 and the lower mold body 2 are rotatably connected by a connecting hinge 201, and the other end of the upper mold body 1 and the lower mold body 2 are fixedly connected by a connecting bolt 2011. The rotatable connection is achieved by the connecting hinge 201, and the fixed connection is achieved by the connecting bolt 2011, so that the upper mold body 1 and the lower mold body 2 can be opened and closed flexibly, which facilitates the installation, replacement and internal cleaning of the mold core 202.

[0034] To facilitate the installation and positioning of the mold core 202, an installation slider 203 for installing the mold core 202 is fixedly connected to the mold core 202. An installation groove 2031 that cooperates with the installation slider 203 is provided on the upper mold body 1. The cooperation between the installation slider 203 and the installation groove 2031 provides guidance and preliminary positioning for the installation of the mold core 202, so that the mold core 202 can be accurately and quickly installed on the upper mold body 1.

[0035] To achieve the function of fixing the mold core 202 by the positioning component 2021, the upper mold body 1 and the lower mold body 2 are each equipped with a positioning component 2021 for fixing the mold core 202 at the corresponding positions. The positioning component 2021 includes a threaded seat 204 fixedly connected to the upper mold body 1. The threaded seat 204 is threadedly connected to the mounting bolt 2041 for fixing the mounting slider 203. Through the cooperation between the threaded seat 204 and the mounting bolt 2041, the mounting slider 203 is pressed and fixed by the threaded seat 204, thereby firmly fixing the mold core 202 to the upper mold body 1. The operation is simple and the fixing effect is good.

[0036] In order to cooperate with the mounting bolt 2041 to fix the mold core 202, the mounting slider 203 has a mounting hole 2042 that matches the mounting bolt 2041 at the corresponding position. The mounting hole 2042 provides an installation position for the mounting bolt 2041, so that the mounting bolt 2041 can accurately pass through the mounting slider 203 and effectively fix the mold core 202.

[0037] To enhance the stability of the mold core 202 installation, two symmetrically arranged positioning sliders 205 are fixedly connected to the mold core 202. The upper mold body 1 has a positioning groove 2051 at the position corresponding to the positioning slider 205, which is used to cooperate with the positioning slider 205. The cooperation between the positioning slider 205 and the positioning groove 2051 further restricts the degree of freedom of the mold core 202, enhances the stability of the mold core 202 installation, prevents the mold core 202 from shaking during operation, and ensures the sizing quality.

[0038] In summary, in this embodiment of the present invention, the upper mold body 1 and the lower mold body 2 are opened and closed by connecting hinge 201 and connecting bolt 2011, which facilitates the installation and replacement of the mold core 202. The mold core 202 is initially positioned by the cooperation of the mounting slider 203 with the mounting groove 2031 of the upper mold body 1. The mounting bolt 2041 in the positioning component 2021 passes through the mounting hole 2042 on the mounting slider 203 to fix the mold core 202 on the upper mold body 1. At the same time, the positioning slider 205 on the mold core 202 cooperates with the positioning groove 2051 of the upper mold body 1, which further enhances the stability of the installation of the mold core 202.

[0039] During the sizing process, pressure sensor 301 and diameter gauge 3 are used to monitor the welding wire diameter online. When the welding wire passes through the sizing die, pressure sensor 301 detects the pressure exerted by the sizing die on the welding wire in real time and transmits the data to an external computer. Diameter gauge 3 directly measures the diameter of the welding wire and also transmits the measurement result to the external computer. The computer performs comprehensive analysis of the two sets of data to determine whether the welding wire diameter meets the preset standard. The online diameter measurement function allows operators to monitor the welding wire diameter in real time, adjust the production process promptly, and ensure welding quality.

[0040] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
