Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal processing technology, and specifically relates to a tungsten copper alloy bar straightening machine. Background Technology
[0002] Tungsten-copper alloy rods are composite materials made of tungsten and copper through powder metallurgy processes (such as high-temperature sintering and melt infiltration). They have high density, hardness, high temperature resistance and ablation resistance. The hardness of tungsten-copper alloys can reach 260HB, far exceeding that of ordinary metals. However, they are brittle and have poor plasticity. During the powder metallurgy preparation process, residual stress is easily generated inside, causing the rods to bend naturally after sintering. A straightening machine is needed to straighten the rods.
[0003] In existing technology, tungsten-copper alloy bars pass through multiple sets of rollers in a straightening machine at low speed. The rollers apply basic pressure to initially flatten the S-shaped bend. The position adjustment of the rollers mainly relies on the screw mechanism. However, the determination of the fit between the rollers and the bar is based solely on the naked eye observation of the operator. This is highly dependent on the operator's experience and lacks accurate displacement judgment. There is a risk of repeated adjustments due to misjudgment. It is difficult to ensure that the contact pressure between the rollers and the bar is uniform and consistent, which may lead to insufficient straightening accuracy. Utility Model Content
[0004] The purpose of this invention is to provide a tungsten-copper alloy bar straightening machine. The position of the measuring plate is adjusted by sliding along the moving groove. A reference can be formed on the outside of each roller in the roller group, and the distance of each roller's rise and fall can be accurately judged by its scale bar. This reduces the risk of misjudgment when adjusting the roller group, ensures that the pressure between the roller and the bar is appropriate, and avoids repeated adjustments that are time-consuming and laborious.
[0005] The specific technical solution adopted by this utility model is as follows: A tungsten-copper alloy bar straightening machine includes a roller assembly mounted on one side of a frame. The top of the frame extends outward to form an extension plate. A clamping plate is detachably connected to the outer edge of the extension plate via fastening bolts. A moving groove is formed between the extension plate and the clamping plate along the length direction. A measuring plate is inserted through the moving groove. A through slot is formed in the middle of the measuring plate. Scale strips are symmetrically arranged on the surface wall of the measuring plate on both sides of the through slot. A fall arrestor wing plate is fixedly connected to the top of the measuring plate.
[0006] The extension plate is located above the roller assembly.
[0007] The measuring plate is located on the adjacent outer side of the roller group, and the thickness of the measuring plate is adapted to the width of the moving groove.
[0008] The fall arrestor wing extends upward to form a grip.
[0009] The fall arrestor wing is magnetically attached to the top surface of the extension plate and clamping plate via a magnetic suction plate.
[0010] The clamping plate has grooves on the inner sides of both ends, and the extension plate has corresponding protruding blocks that slide in cooperation with the grooves at both ends.
[0011] The frame has an inwardly recessed receiving groove on one side for the measuring plate to be movably inserted.
[0012] The technical effect achieved by this utility model is as follows: by sliding the measuring plate along the moving groove to adjust its position, a reference can be formed on the outside of each roller of the roller group, and the distance of each roller's rise and fall can be accurately judged through its scale bar, thereby reducing the risk of misjudgment when adjusting the roller group, ensuring that the pressure between it and the bar is appropriate, and avoiding repeated adjustments that are time-consuming and laborious.

Detailed Implementation
[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0016] like Figures 1-5As shown, a tungsten-copper alloy bar straightening machine includes a roller assembly 101 mounted on one side of a frame 1. The top of the frame 1 extends outward to form an extension plate 102, which is positioned above the roller assembly 101. A clamping plate 103 is detachably connected to the outer edge of the extension plate 102 via fastening bolts 105. A moving groove 104, extending along the length direction, is formed between the extension plate 102 and the clamping plate 103. A measuring plate 106 is inserted through the moving groove 104, located adjacent to the outer side of the roller assembly 101. The thickness of the measuring plate 106 is adapted to the width of the moving groove 104. A through groove 107 is provided through the middle of the measuring plate 106. Scale strips are symmetrically provided on the surface of the measuring plate 106 and on both sides of the through groove 107. A fall arrestor wing plate 108 is fixedly connected to the top of the measuring plate 106. The fall arrestor wing plate 108 extends upward to form a grip. The fall arrestor wing plate 108 is magnetically attracted to the top surface of the extension plate 102 and the clamping plate 103 via a magnetic suction plate 109. The clamping plate 103 has grooves 110 on the inner sides of both ends. The extension plate 102 has corresponding protruding inserts 111 that slide in the grooves 110. A receiving groove 112 is recessed inward on one side of the frame 1 for the measuring plate 106 to be movably inserted.
[0017] According to the above structure, when it is necessary to adjust the vertical position of each upper roller in the roller group 101, the measuring plate 106 is pulled out from the receiving groove 112 and then inserted into the moving groove 104 until the anti-fall wing plate 108 is attracted and fixed to the top surface of the extension plate 102 and the clamping plate 103 by the magnetic suction plate 109. At this time, the anti-fall wing plate 108 is hung on the moving groove 104 to prevent the measuring plate 106 from falling downward. Furthermore, after the measuring plate 106 is inserted into the moving slot 104, it is located outside the roller group 101. When the roller group 101 is adjusted and raised by the screw at the top of the frame 1, the movement of the corresponding roller can be observed through the slot 107, and the relative displacement of the top periphery line of the roller can be intuitively judged through the scale bar of the measuring plate 106. Furthermore, after one roller is adjusted, the measuring plate 106 is slightly lifted upwards by the gripping part, and then the measuring plate 106 is moved along the moving groove 104 to the outside of the next roller. The measuring plate 106 is moved down so that the anti-fall wing plate 108 is attracted to the extension plate 102 and the clamping plate 103 again, so as to continue to provide reference measurement during roller adjustment. After the measurement is completed, the measuring plate 106 can be inserted into the receiving groove 112 for storage. Furthermore, by disassembling the fastening bolt 105, the clamping plate 103 and the extension plate 102 can be separated or installed, which facilitates the cleaning of the moving groove 104 and prevents dust and impurities from causing blockage. The clamping plate 103 and the extension plate 102 are assembled, and the groove 110 automatically engages with the insert 111 to further ensure the levelness of the clamping plate 103.
[0018] The working principle of this utility model is as follows: When it is necessary to accurately adjust the vertical position of each upper roller in the roller group 101, the measuring plate 106 can be pulled out from the receiving groove 112 and then embedded into the moving groove 104. After the anti-fall wing plate 108 achieves magnetic adsorption positioning with the top of the extension plate 102 and the clamping plate 103 by means of the magnetic suction plate 109, the anti-fall wing plate 108 is securely hung above the moving groove 104, forming an anti-fall protection mechanism to prevent the measuring plate 106 from sliding down. At this time, the measuring plate 106 is exactly in the outer working position of the roller group 101. Furthermore, when the roller assembly 101 is raised and lowered by the manual screw at the top of the frame 1, the operator can observe the movement trajectory of the corresponding roller in real time through the slot 107 in the middle of the measuring plate 106, and intuitively obtain the relative displacement parameters of the top periphery of the roller based on the scale bars symmetrically distributed on the surface of the measuring plate 106. Furthermore, after adjusting a single roller, gently lift the holding part of the measuring plate 106 to raise it slightly, and then move it horizontally along the moving groove 104 to the next roller station. Press down the measuring plate 106 to make the anti-fall wing plate 108 re-establish magnetic adsorption, continuously providing a measurement reference for subsequent roller adjustments. After the measurement operation is completed, the measuring plate 106 can be properly stored in the receiving groove 112. Furthermore, by loosening the fastening bolt 105, the clamping plate 103 and the extension plate 102 can be easily separated and assembled, which facilitates the thorough cleaning of the moving groove 104, effectively preventing jamming caused by dust and impurities. In addition, the insert 110 will fit into the insert block 111 during installation, ensuring the levelness accuracy of the clamping plate 103.
[0019] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
