Description

Technical Field

[0002] Existing scrap sucker rod remanufacturing equipment often uses fixed structures for feeding, rust removal, and straightening components, which can only accommodate a single specification, such as a sucker rod of a specific diameter. When processing scrap sucker rods of different diameters, core components must be replaced, resulting in cumbersome operation and high adaptation costs. Simultaneously, the grinding pressure of the rust removal components is mostly fixed, unable to be flexibly adjusted according to the degree of rust on the sucker rod. This leads to incomplete treatment of severely rusted areas or over-grinding of slightly rusted areas, hindering continuous feeding and resulting in low overall processing efficiency. Furthermore, the grinding components used for rust removal are mostly integrated designs, requiring replacement of the entire unit after wear. This replacement process requires specialized tools, and the complex transmission structures of each component necessitate individual disassembly and inspection during maintenance, increasing maintenance difficulty and costs.

Detailed Implementation

[0015] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0016] This utility model mentions a device for remanufacturing scrapped sucker rods, such as... Figures 1-5 As shown, it includes: The inner wall of the feeding table 100 is rotatably connected to the feeding roller 120 via bearings, and the feeding roller 120 is provided with several of them. The feeding and positioning assembly includes a first guide rail frame 200, a positioning slide 220 slidably connected to the inner wall of the first guide rail frame 200, and a positioning roller 230 rotatably connected to the inner wall of the positioning slide 220 via a bearing. The positioning roller 230 and the feeding roller 120 cooperate for feeding. The grinding and rust removal assembly includes a drive wheel 350 and a wire wheel 360 that is detachably and fixedly mounted on the outer wall of the drive wheel 350. The straightening assembly includes a support plate 400, a V-shaped groove 410 on the top of the support plate 400, and an adjustable pressure roller 440 above the support plate 400. In use, the scrap sucker rod is placed on the feeding roller 120 of the feeding table 100. The positioning slide 220 of the feeding positioning component slides along the first guide rail frame 200, so that the positioning roller 230 and the feeding roller 120 are in contact with the surface of the scrap sucker rod. The scrap sucker rod is clamped and transported by the cooperation of the two. When the scrap sucker rod is transported to the grinding and rust removal component, the drive wheel 350 drives the wire wheel 360 to rotate. The wire wheel 360 contacts the surface of the scrap sucker rod to grind and remove rust. Then the scrap sucker rod enters the straightening component. The V-groove 410 of the support plate 400 supports the scrap sucker rod. By adjusting the lowering height of the pressure roller 440, pressure is applied to the bent part. Straightening is completed by utilizing the plastic deformation of metal. It is suitable for basic remanufacturing scenarios of sucker rods with small batches and various degrees of bending.

[0017] A servo motor is fixedly installed on the side wall of the feeding table 100. A sprocket is installed on the outer end of each feeding roller 120. A chain is meshed on the outer side of the sprocket. Adjacent feeding rollers 120 are connected by sprocket and chain transmission. Gears are provided on the outer wall of the output shaft of the servo motor and the outer wall of the feeding roller 120 at the starting end. The output shaft of the servo motor is connected to the outer wall of the feeding roller 120 at the starting end by gear meshing transmission. Support legs 110 are installed on the bottom outer wall of the feeding table 100. After the servo motor starts, it drives the feeding roller 120 at the starting end to rotate through gear meshing. Adjacent feeding rollers 120 are synchronously driven through sprockets and chains to achieve continuous conveying of sucker rods. The support legs 110 at the bottom of the feeding platform 100 enhance the stability of the device and prevent vibration from affecting the positioning accuracy during conveying. This structure replaces manual feeding with motor drive, making it suitable for continuous processing of medium-batch sucker rods, reducing manual intervention and improving conveying efficiency.

[0018] like Figure 1 and Figure 2 As shown, the outer walls of the feeding roller 120 and the positioning roller 230 are both provided with arc-shaped grooves. The arc-shaped grooves are used for positioning and feeding the scrapped sucker rod. The first guide rail frame 200 is fixedly installed on the top outer wall of the feeding table 100. The inner walls of the left and right sides of the first guide rail frame 200 are provided with first sliding grooves 210. The inner wall of the first sliding groove 210 is slidably connected to the positioning slide 220. The top outer wall of the positioning slide 220 is rotatably connected to the first screw 240. The outer wall of the first screw 240 is threadedly connected to the inner wall of the first guide rail frame 200. The top outer wall of the first screw 240 is fixedly installed with the first handwheel 241. The arc-shaped grooves of the feeding roller 120 and the positioning roller 230 fit against the outer wall of the sucker rod to prevent deviation during conveying. Rotating the first handwheel 241 drives the first screw 240 to rotate, causing the positioning slide 220 to slide up and down along the first slide groove 210 of the first guide rail frame 200. Adjusting the distance between the positioning roller 230 and the feeding roller 120 adapts to sucker rods of different diameters and is suitable for processing various specifications of scrap sucker rods. Quick changeover is achieved through mechanical adjustment, improving the equipment's versatility.

[0019] like Figure 3 and Figure 4 As shown, the grinding and rust removal assembly includes a second guide rail frame 300. Second slide grooves 310 are formed on the inner walls of the left and right sides of the second guide rail frame 300. L-shaped brackets 320 are slidably connected to the inner walls of the second slide grooves 310. An adjusting seat 330 is fixedly installed between the two sets of L-shaped brackets 320. A drive wheel 350 is rotatably connected to the inner wall of the adjusting seat 330. Teeth are formed on the outer circumference of the rear end of the drive wheel 350. A second servo motor 340 is fixedly installed on the outer wall of the rear end of the adjusting seat 330. A second gear is provided on the output shaft of the second servo motor 340. The second gear meshes with the teeth on the outer wall of the drive wheel 350 for transmission. A wire wheel 360 is installed on the outer wall of the drive wheel 350 via bolts 370. A wire brush 361 is fixedly installed on the inner wall of the wire wheel 360. A second screw 380 is rotatably connected to the top outer wall of the adjusting seat 330. A second handwheel 381 is fixedly installed on the top outer wall of the second screw 380. The second servo motor 340 drives the drive wheel 350 to rotate through gear meshing, which in turn drives the wire wheel 360 and wire brush 361 on the outer wall to rotate at high speed. Rotating the second handwheel 381 causes the second screw 380 to rotate, which drives the adjusting seat 330 to rise and fall along the second slide groove 310 of the second guide rail frame 300. The L-shaped bracket 320 helps to stabilize the position of the adjusting seat, thereby adjusting the height of the wire wheel 360. After the wire brush 361 polishes and removes rust, the detachable wire wheel 360 is easy to replace after wear. It is suitable for fine rust removal of sucker rods with different degrees of rust. The motor drive and pressure adjustment ensure uniform rust removal effect.

[0020] like Figure 5 As shown, the straightening assembly includes an adjusting rail 420, which is fixedly installed on the top outer wall of the feeding table 100. Guide grooves 421 are provided on the inner walls of the left and right sides of the adjusting rail 420. The inner wall of the guide grooves 421 is slidably connected to the lifting frame 430. The inner wall of the lifting frame 430 is rotatably connected to the pressure roller 440. The inner wall of the pressure roller 440 is provided with a straightening groove 441. A servo motor 450 for driving the pressure roller 440 to rotate is fixedly installed on the side wall of the lifting frame 430. The top of the lifting frame 430 is rotatably connected to the lifting screw 460. A third handwheel 461 is fixedly installed on the top of the lifting screw 460. First, based on the diameter of the pipe to be straightened, the lifting frame 430 slides within the guide groove 421 of the adjusting rail 420 to adjust the height of the pressure roller 441, ensuring that the straightening groove 441 on the inner wall of the pressure roller 441 matches the outer surface of the pipe. When the pipe enters the straightening assembly, the servo motor 450 starts and drives the pressure roller 441 to rotate. The rotating pressure roller 441, through the friction between the straightening groove 441 and the pipe, moves the pipe along the feeding direction. Simultaneously, during the rotation of the pressure roller 441, its straightening groove 441 applies uniform radial pressure to the pipe, using this pressure to correct the bent parts of the pipe, gradually restoring the pipe to a straight state during transport, ultimately achieving continuous straightening of the pipe. The fixed installation of the adjusting rail 420 provides stable support for the entire straightening process, while the guide groove 421 ensures precise and stable lifting and lowering adjustment of the lifting frame 430, ensuring the uniformity of pressure from the pressure roller 441 on the pipe and the stability of the straightening effect.

[0021] The working principle of this utility model is as follows: When in use, the remanufacturing process of the scrap sucker rod is completed through the coordinated operation of various components. First, the sucker rod is placed on the feeding roller 120 of the feeding platform 100. The feeding positioning component slides along the first slide groove 210 of the first guide rail frame 200 by adjusting the positioning slide 220, so that the positioning roller 230 and the arc groove of the feeding roller 120 fit the rod body. The distance between the two can be adjusted by rotating the first handwheel 241 to adapt to sucker rods of different diameters (φ22-φ38mm) and achieve precise positioning and conveying. The conveying power is provided by a servo motor, which drives the starting end feeding roller 120 through gear meshing, and drives all feeding rollers to operate synchronously through sprocket and chain transmission to complete the continuous conveying of sucker rods. When the scrap sucker rod enters the grinding and rust removal component, the second servo motor 340 drives the drive wheel 350 to rotate through gear meshing, driving the wire wheel 360 and wire brush 361 to rotate at high speed. Rotating the second handwheel 381 can adjust the adjustment seat 330 to rise and fall along the second slide groove 310 of the second guide rail frame 300, realizing fine grinding and rust removal of different degrees of rust. The wire wheel is detachable for easy replacement. The scrap sucker rod enters the straightening component, and the V-shaped groove 410 of the support plate 400 supports the rod body. By adjusting the descent height of the pressure roller 440, pressure is applied to the bent part, and straightening is completed by utilizing the plastic deformation of the metal. The whole process realizes continuous operation from feeding, specification matching, precise rust removal to efficient straightening, which is suitable for the remanufacturing of scrap sucker rods of different batches, specifications and degrees of rust.
