Description

Technical Field

[0001] The present invention belongs to the technical field of wire welding rod production equipment, and particularly relates to a wire welding rod inlet protection device. Background Art

[0002] The wire welding rod layer winding machine is one of the important equipment in the wire welding rod production process, and it is used to complete the precise layer winding of the wire welding rod. The so-called precise layer winding means that the wire welding rods are evenly arranged layer by layer during the winding process and no wire entanglement occurs. During the process of winding layer by layer into a whole, the wire welding rod must be tightened so that it can be wound more tightly. However, during the stretching process of the high-speed layer winding machine, if the hardness of some parts of the wire welding rod is insufficient or there are small defects in the material, it is easy to be broken. And the wire welding rod is a metal material with ductility and will produce a certain amount of springback. Although the sensor in the production equipment will detect the breakage of the wire welding rod and stop the machine, the impact generated only at the moment of wire welding rod breakage is also likely to cause equipment damage or injury to on-site operators. Therefore, it is necessary to design a protection device to improve the safety during the wire welding rod production process. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0025] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0026] A wire feeding protection device, as Figures 1 to 6 shown, includes a cover body 1, a mounting frame 2 and a rear protection frame 3. The cross-section of the cover body is arc-shaped, and a plurality of rows of wire disturbing rods 4 are provided on its inner wall, and the wire disturbing rods are all arranged obliquely upward; a plurality of wire dividers 5 are arranged at intervals along the length direction of the cover body at the top of the inner wall of the cover body. The wire divider includes a hanging rod 6 and a material dividing rod 7 at the lower end of the hanging rod. The upper end of the hanging rod is fixed to the cover body; the lower edge of the wire disturbing rod is a smooth surface, and an anti-slip structure is provided on the upper edge; connecting plates 15 are symmetrically provided at the rear end of the cover body. The connecting plate includes a main connecting portion 16 and an auxiliary connecting portion 17. The auxiliary connecting portion extends along the length direction of the cover body, and an auxiliary connecting column 19 is provided at the end away from the cover body. A main connecting column 18 is provided at the junction of the main connecting portion and the auxiliary connecting portion. The mounting frame is mounted on the main connecting column, and the rear protection frame is mounted on the auxiliary connecting column.

[0027] Generally, the bottom of the material distributing rod is arc-shaped. The two guiding plates are symmetrically arranged with respect to the hanging rod. The material distributing rod as a whole is a V-shaped mechanism, and guiding portions 8 inclined upward are respectively arranged on both sides thereof. When a welding wire breaks during the production process, the cover body and the protective frame provide effective protection to prevent the welding wire from sweeping upwards and injuring people or damaging the equipment. Moreover, when the welding wire bounces, there is a high probability that it will enter the space above the wire winding rod in the cover body. This not only restricts the welding wire in the vertical direction, but also the anti-slip structure on the upper edge of the wire winding rod or the material distributing rod can prevent the welding wire from further weakening its bounce. The sensor in the production equipment detects the breakage of the welding wire and stops the machine, minimizing the destructive force after the breakage of the welding wire to the greatest extent.

[0028] The lower edge of the material distributing rod has a smooth surface, and an anti-slip structure is provided on the upper edge. As an example, the anti-slip structure is a rubber layer vulcanized and formed on the upper edge of the wire winding rod, or a rubber strip adhesively fixed (along the length direction of the wire winding rod) to the upper edge of the wire winding rod. When the welding wire breaks and bounces up to the wire distributor, it will move obliquely upward along the guiding portion, making it more likely for the welding wire to fall into the space above the wire winding rod. Furthermore, the cover body plays a good protective role.

[0029] The mounting bracket includes two symmetrically arranged frame bodies 9. A connecting portion 11 is provided at the upper end of each frame body, and a fixing portion 12 is provided at the lower end. As an example, the fixing portion is perpendicular to the main structure 10 of the frame body. A connecting hole matching the main connecting column is provided on the connecting portion, and a fixing hole is provided on the fixing portion. The main connecting column passes through the connecting hole, and a threaded section is provided at one end of the main connecting column extending out of the frame body. A nut is screwed on this threaded section, and one end of the main connecting column extending out of the frame body is locked by the nut.

[0030] The rear protective frame includes an arc-shaped protective body 13 and extension arms 14 on both sides of the protective body. Mounting holes matching the auxiliary connecting columns are provided at the ends of the extension arms. The auxiliary connecting columns pass through the mounting holes of the corresponding extension arms. A threaded section is provided at one end of the auxiliary connecting column extending out of the extension arm. A nut is screwed on this threaded section, and one end of the auxiliary connecting column extending out of the extension arm is locked by the nut.

[0031] This device can be fixed to the base or the equipment housing at the exposed position of the welding wire through the mounting bracket, so that the cover body and the protective frame are both above the welding wire. After the welding wire breaks and bounces, the broken part of the welding wire will bounce into the cover body. The cover body provides effective protection to the part of the welding wire near the proximal end (close to the breakage position), while the protective frame can play a role in organizing large fluctuations of the welding wire at the distal end (compared with the part of the welding wire corresponding to the cover body). According to the usage requirements, the nut on the main connecting column can be loosened, the mounting angle of the cover body can be adjusted adaptively, and then the nut can be tightened to lock and fix it. In addition, the nut on the auxiliary connecting column can be loosened, the mounting angle of the protective frame can be adjusted adaptively, and then the nut can be tightened to lock it.

[0032] The structural design of the present invention is reasonable. A cover body is installed on the mounting frame, and a protective frame is also installed on the connecting plate at the rear end of the cover body, which can effectively play a protective role at the moment of wire breakage. The mounting frame on the connecting plate facilitates the installation and fixation of the device, and the installation angles of the protective frame and the cover body can be adaptively adjusted when locking the corresponding nuts, with high flexibility in use and good versatility.

[0033] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
