Description

Technical Field

[0001] This utility model relates to the field of welding electrode processing technology, specifically to a low alloy steel welding electrode processing and cutting device. Background Technology

[0002] In the production and processing of low-alloy steel welding electrodes, cutting is a crucial step to ensure consistent electrode length and meet subsequent use and packaging requirements. Currently, traditional low-alloy steel welding electrode cutting devices mostly employ a mechanical transmission structure, using a fixed cutter and a conveying mechanism to achieve the cutting action. However, these devices have several shortcomings in practical applications: Firstly, due to the special material properties of low-alloy steel welding electrodes, with their high strength and toughness, traditional cutters are prone to wear and dulling after long-term cutting, resulting in uneven cut surfaces and burrs, affecting the welding performance and appearance quality of the electrodes. Secondly, the cutting speed and length adjustment of existing devices are not flexible enough to adapt to the processing needs of different specifications of low-alloy steel welding electrodes. Furthermore, high-speed cutting can easily lead to electrode slippage and inaccurate positioning, reducing production efficiency and cutting accuracy. In addition, some devices lack effective cooling and lubrication mechanisms, and the heat generated during cutting can easily cause localized heat deformation of the welding electrode, further affecting product quality. This also exacerbates cutter wear, increasing production costs and equipment maintenance frequency. Therefore, developing a low-alloy steel welding rod processing and cutting device that can improve cutting accuracy, extend tool life, adapt to multi-specification processing, and has good stability has become an urgent problem to be solved in the industry.

[0003] Utility model patent application number CN202121295597.9 and publication number CN215697590U (hereinafter referred to as "Prior Art 1") discloses a cutting device for processing stainless steel welding rods, including a base. A support plate is fixedly connected to the upper surface of the base. A load-bearing plate is fixedly connected to the outer wall of the support plate. A motor is fixedly installed on the end face of the support plate. A fixed shaft is fixedly connected to the output end of the motor. An L-shaped plate is fixedly connected to the upper surface of the load-bearing plate. Two top plates are fixedly connected to the upper surface of the L-shaped plate. The top ends of the two top plates are rotatably connected to a transmission rod through a bearing.

In use, the connecting rod allows the welding rod to move, which is beneficial to improving work efficiency. The use of a single motor is beneficial to saving costs. However, in practical applications, the outer wall of the welding rod usually has many pits and bumps, which can cause the welding rod to get stuck between the two transmission discs when passing through the transmission discs and cannot be fed. Summary of the Invention

Detailed Implementation

[0026] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0027] Please see Figures 1-4 As shown in the figure, this embodiment discloses a low alloy steel welding electrode processing and cutting device, including a feeding device, a cutting device, and a unloading device; the feeding device is used to feed the welding electrode; the cutting device is used to fix the welding electrode on the feeding device and cut it; the unloading device is used to unload the cut welding electrode.

[0028] The feeding device includes a feeding channel, a mounting frame 101, a feeding assembly, and a slide bar 102. The unloading device is located below the feeding channel, the cutting device is located on the side of the feeding channel, the mounting frame 101 is located on the feeding channel, and the feeding device is located on the mounting frame 101 and is used to feed welding rods on the feeding channel. There are two slide bars 102, both of which are threadedly connected to the mounting frame 101. The ends of the two slide bars 102 are movably provided with sliders 103, which are slidably connected to the mounting frame 101. A pressure roller 104 is provided between the two sliders 103, which is used to contact several welding rods. A spring 105 is sleeved on the slide bar 102, one end of which is connected to the slider 103, and the other end is connected to the mounting frame 101.

[0029] This utility model mainly includes a feeding device, a cutting device, and a discharging device. In actual use, the operator places several welding rods in a row on the feed channel, then rotates the slide bar 102. Under the action of the spring 105, the slide bar 102 drives the slider 103 to move on the mounting frame 101. The slider 103 then drives the pressure roller 104 to move on the mounting frame 101 until the pressure roller 104 contacts several welding rods. Then, the slider 103 stops rotating, and several welding rods are fed through the feeding assembly. After feeding, the welding rods are cut by the cutting device, and finally, the welding rods are discharged through the discharging device. During the feeding process, because the welding rods have pits and bumps, they will squeeze the pressure roller 104. The pressure roller 104 drives the slider 103 to squeeze the spring 105, causing the slider 103 to slide on the slide bar 102, which cancels out the pits and bumps on the welding rods and effectively avoids jamming between the welding rods and the pressure roller 104 and the feeding assembly during the feeding process.

[0030] In some embodiments, the feed channel mainly consists of three parts: a first feed channel 106, a second feed channel 107, and a third feed channel 108. The mounting frame 101 is disposed between the first feed channel 106 and the second feed channel 107, and the cutting device is disposed between the second feed channel 107 and the third feed channel 108. The first, second, and third feed channels are flush with each other, and the feeding device is disposed at the bottom of the third feed channel 108.

[0031] In actual use, the first material channel 106, the second material channel 107 and the third material channel 108 are interconnected. The first material channel 106 is mainly used to place several welding rods. The initial position of the welding rods is placed between the first material channel 106, the pressure roller 104 and the feeding assembly. The welding rods are mainly cut on the second material channel 107 and the third material channel 108. The unloading device pushes the cut welding rods out of the third material channel 108 for collection.

[0032] In some embodiments, the feeding assembly includes a motor 109 and a roller 110. The motor 109 is disposed on the side of the mounting frame 101. The output shaft of the motor 109 passes through the mounting frame 101 and is connected to the roller 110. The roller 110 is located directly below the pressure roller 104. The outer wall of the roller 110 is used to contact a plurality of welding rods.

[0033] In actual use, when it is necessary to feed several welding rods, the operator starts the motor 109 to rotate. After the motor 109 rotates, it drives the roller 110 to rotate. After the roller 110 rotates, it cooperates with the pressure roller 104 to achieve the purpose of feeding several welding rods forward.

[0034] In some embodiments, the mounting bracket 101 is provided with a sliding groove 111, and a U-shaped stop 112 is provided on the sliding groove 111. The slider 103 is slidably connected with the sliding groove 111 and the U-shaped stop 112, and the roller 110 is rotatably connected with the slider 103 after passing through the U-shaped stop 112.

[0035] In actual use, the purpose of setting the U-shaped stop 112 is to limit the position of the slider 103 so that the slider 103 can only slide inside the sliding groove 111.

[0036] In some embodiments, a feeding trough 113 is provided on the material channel.

[0037] In actual use, the purpose of setting the feeding groove 113 is to limit the lateral position of several welding rods, so as to facilitate the installation of welding rods.

[0038] In some embodiments, the cutting device includes a first cylinder 114, a cutter 115, and a stabilizing component. The first cylinder 114 and the stabilizing component are disposed between the second material channel 107 and the third material channel 108, and are located on the left and right sides of the second material channel 107 and the third material channel 108. The cutter 115 is disposed at the movable end of the first cylinder 114 and slides with the second material channel 107 and the third material channel 108. The cutter 115 is used to cut a plurality of welding rods, and the stabilizing component is used to fix the plurality of welding rods.

[0039] In actual use, when the welding rod is located between the cutting devices and needs to be cut, the operator activates the stabilizing component to fix the welding rod, and then drives the first cylinder 114 to start. After the first cylinder 114 extends, it drives the cutter 115 to cut several welding rods. While fixing the welding rod, the stabilizing component makes way for the cutter 115 until the cutter 115 passes through the second material channel 107 and the third material channel 108, completing the cutting of the welding rod.

[0040] In some embodiments, the stabilizing component includes a support frame 116, a second cylinder 117, and a pressure head 118. The support frame 116 is disposed between the second feed channel 107 and the third feed channel 108. The second cylinder 117 is disposed on the support frame 116. The pressure head 118 is disposed at the movable end of the second cylinder 117 and is used to contact a plurality of welding rods.

[0041] In actual use, when it is necessary to fix the welding rods, the operator controls the extension of the second cylinder 117. After the second cylinder 117 extends, it drives the pressure head 118 to move down until the end of the pressure head 118 is in contact with several welding rods, thus completing the fixation of several welding rods.

[0042] In some embodiments, the pressure head 118 is provided with a clearance groove 119, which is used to make way for the cutter 115.

[0043] In actual use, the purpose of setting the clearance groove 119 is to facilitate the clearance of the cutter 115, so that the cutter 115 can better cut the welding rod.

[0044] In some embodiments, the feeding device includes a feeding box 120, a third cylinder 121, and a push plate 122. The feeding box 120 is disposed below the third material channel 108, the third cylinder 121 is disposed on the side of the third material channel 108 away from the feeding box 120, and the push plate 122 is disposed at the end of the third cylinder 121. The push plate 122 is used to slide in connection with the third material channel 108.

[0045] In actual use, after the welding rod is cut, the operator drives the third cylinder 121 to extend. After the third cylinder 121 extends, it drives the push plate 122 forward. The push plate 122 pushes several cut welding rods into the feeding box 120 to complete the collection.

[0046] In some embodiments, there are two feeding boxes 120, and the two feeding boxes 120 are connected to each other.

[0047] In actual use, the purpose of setting up two feeding boxes 120 is twofold: first, to increase the storage capacity of welding rods, and second, to prevent welding rods from rolling off the third feeding channel 108 onto the table.
