Description

Technical Field

[0001] This utility model relates to the field of guardrail processing technology, specifically a polishing machine for guardrail processing. Background Technology

[0002] Highway guardrails, residential fences, garden fences, and other protective railings require surface grinding and polishing during production to remove defects such as oxide layers, burrs, and scratches, thereby improving surface smoothness, flatness, and rust resistance. Polishing machines are commonly used equipment, typically consisting of a frame and a conveyor mechanism. The guardrails are transported to the polishing area via the conveyor mechanism, where fixed polishing components polish the surface.

[0003] Round tubes are a common component of guardrails. Since round tubes come in different diameters and lengths, polishing machines need to be adapted to the clamping components during use. The compatibility is generally poor. At the same time, the generated debris is scattered randomly in the work area, which not only pollutes the processing environment and endangers the health of operators, but also accumulates at the transmission components of the equipment, aggravating component wear and shortening the service life of the equipment. Utility Model Content

[0004] The technical problem this invention aims to solve is that it has limited compatibility with polishing round tubes of different diameters, and the resulting debris cannot be collected and processed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model proposes a polishing machine for guardrail processing, comprising a polishing box, a polishing table inside the polishing box, a cutting assembly and a transmission and conveying assembly inside the polishing table, the cutting assembly including two sets of guide rails mounted on the polishing table, and two sets of slide blocks slidably mounted on the two sets of guide rails, the polishing table also having two sets of screw seats, and a drive screw rotating on the two sets of screw seats, the drive screw having two sets of threads with opposite directions, the two sets of slide blocks being threadedly connected to the two sets of threads with opposite directions respectively, a drive motor being mounted on the front side of the polishing box and the motor's power output shaft being connected to the drive screw, and a grinding assembly being mounted on the two sets of slide blocks;

[0006] The grinding assembly includes a grinding motor bolted to a set of slides, a grinding wheel on the power output shaft of the grinding motor, a C-shaped support plate on another set of slides, and an auxiliary pressure roller on the side of the support plate opposite to the grinding wheel.

[0007] Preferred technical solution 1: The polishing box has an inlet and an outlet on both sides respectively. The transmission and conveying assembly includes a base 1 and a base 2 set on the polishing table. The base 1 is closer to the inlet and higher than the base 2. The base 2 is closer to the outlet. The base 1 and base 2 are provided with four sets of support seats and two sets of support rollers. The two sets are rotatably mounted on the two opposite support seats. The support rollers are inclined. A transmission motor is also provided on one of the support seats to drive the rotation of the support rollers.

[0008] Preferred technical solution 2: A bracket is provided on the polishing table and a collection groove is provided on the bracket. The collection groove is correspondingly provided with the support roller and located below the support roller. The support roller is inclined and has a discharge port on the lower side. A storage compartment is provided inside the polishing box and is connected to the discharge port through a discharge pipe.

[0009] Preferred technical solution 3: Protective curtains are provided on the inlet and outlet.

[0010] Preferred technical solution four: The top of the polishing box is hinged with an inspection door, and auxiliary support frames are provided on both sides of the polishing box below the inlet and outlet.

[0011] Preferred technical solution five: A controller is provided on the front side of the polishing box, and the drive motor, transmission motor and grinding motor are all electrically connected to the controller.

[0012] The present invention proposes a polishing machine for guardrail processing, and the beneficial effects achieved by adopting the above structure are as follows:

[0013] (1) By driving the drive screw with the reverse thread group through the drive motor, the two sets of slides move synchronously in opposite directions along the linear guide rail. The distance between the grinding wheel and the auxiliary pressure roller can be flexibly adjusted to meet the polishing needs of round tube guardrails with different diameter specifications. At the same time, the polyurethane support roller with the inlet end higher than the outlet end and the inclination angle of 5 to 10°, together with the drive motor to drive the round tube to rotate and feed automatically, further improves the stable clamping and continuous processing adaptability of round tubes with different diameters. There is no need to frequently change the fixture, which significantly broadens the applicable scenarios of the equipment.

[0014] (2) The round tube achieves synchronous action of rotation and slow feeding under the action of the support roller. The grinding wheel can perform all-round and uniform grinding on the outer circumference of the round tube, avoiding the problem of uneven grinding caused by manual adjustment of angle, and improving the polishing quality. The transparent PC material dust cover can be quickly disassembled, which can prevent debris from splashing into the grinding motor and affecting the operation of the equipment, and facilitates real-time observation of the grinding status, reducing downtime for inspection. Combined with the automated clamping, transmission and grinding process, it greatly reduces manual intervention and improves the overall efficiency of guardrail processing.

[0015] (3) The stainless steel collection trough accurately receives the grinding debris under the support roller and guides it into the collection bin inside the polishing box through the discharge port and discharge pipe, realizing the centralized collection of debris, avoiding debris from scattering and polluting the processing environment, and reducing the amount of subsequent cleaning work; at the same time, the PVC soft curtains at the inlet and outlet can open and close according to the diameter of the round pipe, which can effectively block debris from splashing outside the polishing box. Combined with the closed structure of the polishing box, it not only protects the health of the operators, but also reduces the environmental treatment cost caused by debris diffusion, which meets the requirements of green processing.

[0023] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0024] Example 1

[0025] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A polishing machine for processing guardrails includes a polishing box 1, a polishing table is provided inside the polishing box 1, a cutting component 2 and a transmission and conveying component 3 are provided inside the polishing table, the cutting component 2 includes two sets of guide rails 4 set on the polishing table, and two sets of slide blocks 7 slidably set on the two sets of guide rails 4, the guide rails 4 are linear guide rails of model SBR16-800, the length of the guide rails 4 is set according to the space inside the polishing box 1, which is 1200-1800mm, two sets of screw seats 5 are also provided on the polishing table, and a drive screw 6 is rotatably mounted on the two sets of screw seats 5, and two sets of threaded groups with opposite thread directions are provided on the drive screw 6, the two sets of slide blocks 7 are respectively threadedly connected to the two sets of threaded groups with opposite thread directions, a drive motor 8 is provided on the front side of the polishing box 1 and the motor power output shaft is connected to the drive screw 6, and a grinding component is provided on the two sets of slide blocks 7;

[0026] The grinding assembly includes a grinding motor 9 bolted to a set of slides 7. A grinding wheel 10 is mounted on the power output shaft of the grinding motor 9. A C-shaped support plate 11 is mounted on another set of slides 7. An auxiliary pressure roller 12 is mounted on the side opposite to the grinding wheel 10 on the support plate 11. The two sets of slides 7 are driven by a drive motor 8 to press and grind the outer diameter of the round tube. A dust cover made of transparent PC material is mounted on the outside of the grinding motor 9. It is connected to the slides 7 by a buckle and can be quickly disassembled to prevent debris from splashing into the motor.

[0027] like Figure 4As shown, the polishing box 1 has an inlet 13 and an outlet 14 on both sides. To make polishing more convenient and efficient, the transmission and conveying assembly 3 includes a base 15 and a base 2 16 mounted on the polishing table. The base 15 is closer to the inlet 13 and higher than the base 2 16, while the base 2 16 is closer to the outlet 14. Four sets of support seats 17 are mounted on the base 15 and the base 2 16, and two sets of support rollers 18 are also provided. The two sets of support rollers 18 are rotatably mounted on the two opposite support seats 17, and the support rollers 18 are inclined. The inclination angle of the outlet 13 end being higher than that of the outlet 14 end is 5 to 10 degrees. A drive motor 19 is also provided on a set of support seats 17 to drive a set of support rollers 18 to rotate. When the round tube is placed on the two sets of support rollers 18, the rotation of the support rollers 18 realizes the rotation and grinding of the round tube, while moving slowly towards the outlet 14. The two sets of support rollers 18 are made of polyurethane and are rotatably connected to the two sets of support seats 17 at opposite ends through the rotating shafts at both ends. The axes of the two sets of support rollers 18 are parallel, and their installation angle is achieved by the height difference between the base 15 and the base 2 16.

[0028] Protective curtains are installed at inlet 13 and outlet 14. These removable protective curtains are made of PVC soft curtains, 1-2mm thick, with slat widths of 10-15mm and adjacent slat overlaps of 5-10mm. When the protective curtains hang naturally, they completely cover inlet 13 and outlet 14. When a round tube passes through, the slats can adaptively open and close according to the diameter of the tube, effectively preventing grinding debris from splashing outside the polishing box 1. An inspection door 24 is hinged to the top of the polishing box 1, and auxiliary support frames 25 are installed on both sides of the polishing box 1 below inlet 13 and outlet 14.

[0029] Example 2

[0030] Based on Example 1, such as Figure 4 As shown, in order to collect the splatter generated during polishing, a support 20 is set on the polishing table, and a collection groove 21 is set on the support 20. The collection groove 21 is set correspondingly to the support roller 18 and is located below the support roller 18. The support roller 18 is inclined and has a discharge port on the lower side. A storage bin 22 is set inside the polishing box 1 and is connected to the discharge port through a discharge pipe 23. It is made of stainless steel plate welded and has a U-shaped cross section. The length is 50-100mm longer than the support roller 18 and the width is 30-50mm larger than the distance between the two sets of support rollers 18. The bottom of the groove is inclined to one side at an angle of 3-5°. The opening of the collection groove 21 faces upward and the edges are rolled to prevent debris from splashing out of the groove.

[0031] The polishing box 1 is equipped with a controller 26 on the front side, and the drive motor 8, transmission motor 19 and grinding motor 9 are all electrically connected to the controller 26.

[0032] Material feeding stage

[0033] Align one end of the guardrail tube to be polished with the inlet 13 of the polishing box 1. With the support of the auxiliary support frame 25, slowly push the tube so that it passes through the PVC soft curtain at the inlet 13. The curtain will open and close adaptively with the diameter of the tube. Place the tube on the two sets of support rollers 18 on the polishing table base 15 and base 2 16. Since the support rollers 18 are inclined at an angle of 5-10° with the inlet 13 end higher than the outlet 14 end, and the axes of the two sets of support rollers 18 are parallel, the tube will remain stably placed on the support rollers 18 under its own weight. At the same time, adjust the position of the tube on the support rollers 18 to ensure that the part of the tube to be polished is located in the corresponding area between the grinding wheel 10 and the auxiliary holding roller 12.

[0034] Polishing and grinding stage

[0035] After setting the polishing parameters using the controller 26 on the front of the polishing box 1, press the start button to simultaneously start the drive motor 8, transmission motor 19, and grinding motor 9. The drive motor 8 drives the drive screw 6 to rotate. Since the two sets of threads with opposite directions on the drive screw 6 are threadedly connected to the two sets of slides 7, the two sets of slides 7 will move towards each other along the linear guide rail 4. The grinding wheel 10 installed on one set of slides 7 and the auxiliary holding roller 12 on the C-shaped support plate 11 on the other set of slides 7 will also move towards each other until the auxiliary holding roller 12 is tightly pressed against one side of the round tube, and the grinding wheel 10 contacts the other side of the round tube and reaches the appropriate grinding pressure. At this time, the controller 26 will automatically control the drive motor 8 to stop running and maintain the current holding and grinding state. The drive motor 19 drives a set of support rollers 18 to rotate. Under the action of friction, the two sets of support rollers 18 drive the round tube to rotate. At the same time, due to the inclined setting of the support rollers 18, the round tube will slowly move towards the outlet 14 while rotating. The grinding wheel 10 performs comprehensive and uniform polishing on the outer surface of the rotating and moving round tube. During the polishing process, the transparent PC material dust cover will effectively prevent the debris generated during polishing from splashing into the polishing motor 9, while the PVC soft curtains at the inlet 13 and outlet 14 can block the debris from splashing out of the polishing box 1.

[0036] IV. Debris Collection and Processing Stage

[0037] During the polishing process, the debris generated falls due to gravity into the collection groove 21 located below the support roller 18 and corresponding to the support roller 18. Since the bottom of the collection groove 21 is inclined to one side at an angle of 3-5°, and a discharge port is provided on the lower side of the support roller 18, the debris moves along the inclined bottom of the collection groove 21 towards the discharge port. It then enters the storage chamber 22 inside the polishing box 1 through the discharge pipe 23 connected to the discharge port for collection. When the polishing work is completed or when a certain amount of debris accumulates in the storage chamber 22, the cleaning door of the polishing box 1 can be opened to clean and dispose of the debris in the storage chamber 22.
