Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, specifically a wire rotary grinding device. Background Technology

[0002] Wire rod is the smallest type of hot-rolled steel with the smallest cross-sectional dimensions. In my country, hot-rolled round steel in coils with diameters ranging from 5 to 9 mm in eight different specifications is generally called wire rod. Because wire rod is delivered in coils, it is also called wire rod. The concept of wire rod is slightly different in foreign countries than in my country. In addition to the circular cross-section, there are other shapes. Its diameter varies depending on the demand and production technology level. According to the different rolling mills, it can be divided into high-speed wire rod (high wire) and ordinary wire rod (ordinary wire).

[0003] An existing patent (authorization announcement number: CN217344744U) discloses a wire grinding device. When grinding wire, the handle is turned according to the size of the wire, so that the screw drives the moving plate to move, thereby changing the distance between the support column and the grinding wheel. The wire passes between two symmetrically arranged first clamping members, passes through the clearance hole between two symmetrically arranged second clamping members, then passes between the grinding wheel and the support column, and finally exits the mounting box through another clearance hole.

[0004] However, the above-mentioned technical solutions still have certain drawbacks. The above-mentioned device grinds the surface of the wire with a grinding wheel. During the grinding process, some rubber debris is generated on the surface of the wire. Most of it falls onto the surface of the workbench and needs to be cleaned by the staff. A small portion of it adheres to the surface of the grinding wheel, thereby changing the contact state between the grinding wheel and the surface of the wire. On the one hand, the debris will cause uneven distribution of the grinding pressure of the grinding wheel on the wire, resulting in a decrease in the grinding accuracy of the wire surface, and the occurrence of local over-grinding or under-grinding, which affects the product quality. On the other hand, as the grinding wheel continues to rotate, the debris will gradually embed into the surface of the grinding wheel, causing accelerated wear of the grinding wheel, reducing the service life of the grinding wheel, and increasing the equipment maintenance cost. Therefore, a wire rotary grinding device is proposed. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-5As shown, a wire rotary polishing device includes a worktable body 100, a support frame 110 fixedly mounted on the upper surface of the worktable body 100, a clamping assembly 130 provided on one side of the support frame 110, a mounting frame 140 fixedly mounted on the top of the inner cavity of the support frame 110, a polishing wheel 150 rotatably connected to the inner side of the mounting frame 140, a motor 151 for driving the polishing wheel 150 to rotate fixedly mounted on one side of the mounting frame 140, an adjustment assembly 160 provided on one side of the inner cavity of the support frame 110, and an air blowing assembly 2 provided on the top of the support frame 110. 00, the air blowing assembly 200 includes a mounting plate 2950 fixedly connected to one side of the mounting bracket 140. An air storage box 2930 is fixedly mounted at the bottom of the mounting plate 2950. Multiple equally spaced nozzles 2940 are fixedly connected to the bottom of the air storage box 2930. An air outlet pipe 2920 is fixedly connected to the top of the air storage box 2930. The other end of the air outlet pipe 2920 extends through to the top of the support bracket 110, and the other end of the air outlet pipe 2920 is equipped with a reciprocating pull-out assembly for continuously supplying air to the nozzles 2940. The reciprocating pull-out assembly includes a fixed mounting... A fixed plate 210 is located on one side of the top of the support frame 110. A rotating shaft 220 is passed through the fixed plate 210 via a bearing. A turntable 240 is fixedly connected to one end of the rotating shaft 220. A movable column 250 is fixedly connected to the edge of the turntable 240 away from the rotating shaft 220. A movable frame 260 is movably connected to the outside of the movable column 250. A movable rod 270 is fixedly connected to the center of one side of the movable frame 260. A piston 280 is fixedly connected to the other end of the movable rod 270. A sleeve 290 is movably sleeved on the outside of the piston 280. 90 is fixedly connected to the top of the support frame 110 via a fixed base. One end of the air outlet pipe 2920 is fixedly connected to the bottom end of the sleeve 290. The bottom end of the outer wall of the sleeve 290 is fixedly connected to the air inlet pipe 2910. One-way valves are provided in one end of both the air inlet pipe 2910 and the air outlet pipe 2920. The outer wall of the rotating shaft 220 away from the turntable 240 and the outer wall of the output end of the motor 151 are both fixedly sleeved with transmission wheels. The two sets of transmission wheels are connected by a synchronous belt 230. A through groove is provided on the top of the support frame 110 to facilitate the passage of the synchronous belt 230.

[0029] In this embodiment, after the wire is placed, the motor 151 is started, and the output of the motor 151 drives the grinding wheel 150 to grind the wire. At the same time, the synchronous belt 230 drives the rotating shaft 220 to rotate synchronously, thereby driving the turntable 240 to rotate. At this time, the movable column 250 on the turntable 240 begins to perform circular motion, driving the movable frame 260 to begin to reciprocate in the horizontal direction, thereby driving the movable rod 270 and the piston 280 to perform reciprocating pulling motion within the sleeve 290. When the movable frame 260 drives the movable rod 270 and the piston 280 to move towards the top of the inner cavity of the sleeve 290, a negative pressure is generated inside the sleeve 290, and gas flows through the air inlet pipe 2 910 enters the sleeve 290. When the movable frame 260 drives the movable rod 270 and the piston 280 to move towards the bottom of the inner cavity of the sleeve 290, the piston 280 squeezes the gas in the sleeve 290 into the air outlet pipe 2920, and then into the air storage box 2930. Finally, the gas is sprayed out by multiple nozzles 2940. It is worth noting that the nozzles 2940 are set at the outer tangent position of the grinding wheel 150, so that they can be aimed at cleaning the rubber debris adhering to the outer wall of the grinding wheel 150. This ensures that the pressure distribution on the outer wall of the grinding wheel 150 is always uniform, improves the grinding accuracy of the wire surface, and thus improves product quality; it also extends the service life of the grinding wheel 150.

[0030] In one embodiment, such as Figure 1 and Figure 3 As shown, the support frame 110 has clearance holes 120 on both sides to facilitate the passage of wires. The clamping assembly 130 includes two sets of symmetrically arranged fixing boxes 131, which are located above and below the clearance holes 120 on one side of the support frame 110. Each fixing box 131 has a sliding seat 132 slidably connected inside. Multiple equidistant springs 133 are fixedly connected between the bottom of the inner cavity of each fixing box 131 and the bottom of the sliding seat 132. The tops of the two sets of sliding seats 132 are rotatably connected to... Rotating roller 134: When grinding the wire, the wire passes through the relief hole 120, and then the two sets of moving seats 132 are pulled to make the wire pass through smoothly and exit from the relief hole 120 at the other end. The elastic potential energy of the spring 133, together with the rotating roller 134, presses the wire. The rotating roller 134 can reduce the friction when the wire moves. At the same time, under the action of the pushing member, the two symmetrically arranged rotating rollers 134 can move in opposite directions, so that wires of different sizes can be pressed.

[0031] In one embodiment, such as Figure 1 and Figure 4As shown, the adjustment assembly 160 includes a lead screw 161 longitudinally disposed on one side of the inner cavity of the support frame 110. A threaded sleeve 162 is threadedly connected to the outer wall of the lead screw 161. A movable plate 163 is fixedly connected to one end of the threaded sleeve 162. Multiple support columns 165 are rotatably connected to the front side of the movable plate 163. The top end of the lead screw 161 extends through to the top of the support frame 110 and is fixedly mounted with a handwheel 166. Two sets of symmetrically arranged guide blocks 164 are fixedly mounted on the rear side of the inner cavity of the support frame 110. A guide groove matching the guide block 164 is opened on the side of the movable plate 163 away from the support column 165. When the operator rotates the handwheel 166, the lead screw 161 is rotated, thereby causing the threaded sleeve 162, which is threadedly connected to it, to move up and down. This causes the movable plate 163 and the support column 165 to move up and down synchronously with the cooperation of the guide block 164 and the guide groove, thereby changing the distance between the support column 165 and the grinding wheel 150. By setting the support column 165, the wire can be supported.

[0032] In one embodiment, such as Figure 1 As shown, a storage groove 170 is provided on the upper surface of the workbench body 100 and directly below the grinding wheel 150. A collection drawer 180 is slidably provided in the storage groove 170. One end of the collection drawer 180 extends through to the outside of the workbench body 100 and is fixedly installed with a handle. Rubber debris generated during wire grinding and debris adhering to the outer wall of the grinding wheel 150 blown off by the air blowing component 200 all fall into the collection drawer 180 and are collected. After a period of time, the staff will pull out the collection drawer 180 to collect and dispose of the debris, thereby improving the cleaning efficiency of the staff.

[0033] The above embodiment discloses a wire rotary polishing device, wherein, when the motor 151 is started, the output end of the motor 151 drives the polishing wheel 150 to polish the wire. At the same time, the synchronous belt 230 drives the rotating shaft 220 to rotate synchronously, thereby driving the turntable 240 to rotate. At this time, the movable column 250 on the turntable 240 begins to perform circular motion, driving the movable frame 260 to begin to reciprocate in the horizontal direction, thereby driving the movable rod 270 and the piston 280 to perform reciprocating pulling motion within the sleeve 290. When the movable frame 260 drives the movable rod 270 and the piston 280 to move towards the top of the inner cavity of the sleeve 290... A negative pressure is generated inside the sleeve 290, and gas enters the sleeve 290 through the air inlet pipe 2910. When the movable frame 260 moves the movable rod 270 and the piston 280 to the bottom of the inner cavity of the sleeve 290, the piston 280 squeezes the gas inside the sleeve 290 into the air outlet pipe 2920, and then into the air storage box 2930. Finally, the gas is sprayed out by multiple nozzles 2940, which cleans the rubber debris adhering to the outer wall of the grinding wheel 150. This ensures that the pressure distribution on the outer wall of the grinding wheel 150 is always uniform, improves the grinding accuracy of the wire surface, and thus improves product quality; it also extends the service life of the grinding wheel 150.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
