Description

Technical Field

[0001] The invention belongs to the technical field related to polishing, and specifically discloses a polishing device for producing arc-shaped stainless steel castings. Background Art

[0002] Arc angle steel is a commonly used profile in the construction and machinery manufacturing fields. However, the surface treatment of the gaps on both sides of the curved angle steel has long been a technical bottleneck. During hot processing (such as casting and hot rolling), the gap area is prone to three typical defects: Stubborn oxide scale: The dense oxide layer formed at high temperature (especially at the root of the gap) is embedded in the matrix in a wedge shape. Traditional grinding wheels are difficult to completely peel off due to the limited contact angle. Curling burrs and flash: The burrs generated by the stamping / cutting process can be up to 1-3mm high, forming a curled structure at the corners. Conventional tools cannot penetrate deep enough to clean them. Welding bulge: Thermal stress causes the gap area to bulge and deform, forming a local protrusion (commonly known as a "bulge"), which further hinders the surface smoothing process and therefore needs to be improved.

Then, the L-shaped seats and elastic moving parts at both ends are driven to approach each other, causing the fixed block and scraping mechanism to be located on the planes on both sides of the arc-shaped angle steel, and polishing is performed synchronously.

[0014] By setting up an elastic moving part, an adaptive buffer force can be provided by the spring, so that the fixed block automatically floats along the curvature of the arc-shaped angle steel, ensuring that the bevel grinding head on the outer surface of the front end of the fixed block cuts into the burrs and oxide layers during the reciprocating movement, thereby fully processing them.

[0015] Through the scraping mechanism, the high-speed rotation of the rotating head allows the cross diamond knife to grind the more stubborn bulges, which is convenient for the later bevel cutting and scraping with the knife, and is more labor-saving. In addition, under the telescopic adjustment of the cylinder, the position of the gap and inner surface on both sides of the arc angle steel can be adjusted to ensure that both sides of the arc angle steel are relatively flat. When the shaft rotates, the chip blowing wind wheel also rotates synchronously to remove the debris. BRIEF DESCRIPTION OF THE DRAWINGS

The X-axis driving mechanism 6 can drive the lifting assembly to move horizontally through the slide 5.

[0021] The Z-axis drive mechanism 3 and the X-axis drive mechanism 6 are composed of structures such as linear guides, motor groups, and screw rod groups.

[0022] The scraping mechanism is used to scrape off the bulges at the gaps on both sides of the arc angle steel 17.

[0023] The lifting assembly includes a first hydraulic cylinder 7 fixedly mounted inside the slide 5, the telescopic end of the first hydraulic cylinder 7 is connected to the upper surface of the frame 8, the clamping mechanism includes a sleeve 13 arranged at the lower outer side of the stand 2, the outer side of the sleeve 13 is connected to a fixed plate 9 through a connecting frame 14, the outer surfaces of both sides of the fixed plate 9 are provided with positioning plates 10, a pneumatic push rod 16 is provided inside the positioning plate 10, and a chuck 18 is provided at the telescopic end of the pneumatic push rod 16, one end of the chuck 18 is abutted against the end of the arc angle steel 17, a second hydraulic cylinder 12 is fixedly provided on the upper surface of the base 1 and close to the lower side of the arc angle steel 17, and the telescopic end of the second hydraulic cylinder 12 is connected to the support plate 11; The first hydraulic cylinder 7 can drive the frame 8 above the slide 5 to fine-tune it up and down; Under the connection between the sleeve 13 and the connecting frame 14, the fixing plate 9, the positioning plate 10, the pneumatic stop rod 16, and the chuck 18 can be stably installed on one side of the stand 2; The telescopic end of the second hydraulic cylinder 12 pushes the support plate 11 upward, so that the outer bottom of the arc angle steel 17 is completely in contact with the support plate 11 to prevent vibration during processing. When the arc angle steel 17 is placed on the inner surface of the support plate 11 and lifted upward to the fixed plate 9, the pneumatic push rods 16 on both sides are started to push the chuck 18 against the two ends of the arc angle steel 17 to ensure the stability of the workpiece during processing.

[0024] The two-way driving member includes a hanging sleeve rod 20 fixedly arranged on the inner top wall of the frame 8, a two-way telescopic rod 19 is arranged inside the hanging sleeve rod 20, and an elastic moving member at a corresponding position is connected to the telescopic end of the two-way telescopic rod 19, and the elastic moving member includes an L-shaped seat 23 fixedly arranged at the telescopic end of the two-way telescopic rod 19, a fixed rod 21 is inserted inside the L-shaped seat 23, a telescopic cylinder 25 is slidably sleeved on the lower outside of the fixed rod 21, and a spring 24 is provided on the outside of the fixed rod 21, and both ends of the spring 24 are respectively connected to the outer surface of the side close to each other of the telescopic cylinder 25 and the L-shaped seat 23, a clamping block 26 is sleeved on the lower outside of the telescopic cylinder 25, and a guide rod 22 is provided on one side of the L-shaped seat 23, which slides with the frame 8, and the rotating member includes a movable disk 27 rotatably arranged on one side of the clamping block 26, and one end of the movable disk 27 is connected to the fixed block 31; The bidirectional telescopic rod 19 contracts, driving the L-shaped seats 23 on both sides to move toward each other, so that the fixed block 31 is close to the planes on both sides of the arc angle steel 17. When the X-axis drive mechanism 6 drives the slide 5 to move laterally, the spring 24 compresses and pushes the telescopic cylinder 25 to slide adaptively along the outside of the fixed rod 21, forcing the bevel grinding head 32 to always fit in the plane of the arc angle steel 17. If there is a sudden change in the curvature, the movable disk 27 allows the fixed block 31 to deflect at a slight angle by rotating, ensuring that the bevel grinding head 32 fits in at all angles, peeling off the oxide scale and polishing.

[0025] When the fixing block 31 moves to the highest point at both ends of the arc angle steel 17, the telescopic cylinder 25 approaches the L-shaped seat 23. Conversely, when it reaches the lowest point, the telescopic cylinder 25 moves away from the L-shaped seat 23. During this period, the spring 24 can be adaptively compressed according to the curvature of the arc.

[0026] The scraping mechanism includes a limit frame 30 fixedly arranged on the outer side of the fixed block 31, a slide 28 is slidably installed inside the limit frame 30, a turning mechanism is provided on the inner side of the slide 28, and the turning mechanism includes a rotating shaft 33 that rotates and penetrates the inner side of the slide 28. A motor 29 is provided at one end of the rotating shaft 33, and the motor 29 is fixedly installed on the outer side of the limit frame 30. A rotating head 37 is provided at the end of the rotating shaft 33 away from the motor 29, and a cross diamond crushing knife 35 is provided at the end of the rotating head 37. Scrapers 36 are provided at equal distances along the circumferential direction on the outside of the rotating head 37, and multiple groups of chip blowers are provided on the outside of the rotating shaft 33 and at the rear end of the rotating head 37. The wind wheel 34 and the motor 29 drive the rotating shaft 33 to rotate, so that the rotating head 37 can drive the cross diamond crushing knife 35 to rotate rapidly, thereby crushing the bulge. At the same time, the rotating shaft 33 drives the chip blowing wind wheel 34 to rotate, generating a top box airflow to blow the debris away from the processing area. A cylinder 38 is installed above the inner part of the limit frame 30. The telescopic end of the cylinder 38 is connected to the upper surface of the slide 28. The cylinder 38 pushes the slide 28 up and down, which can make the rotating head 37 and the scraper 36 penetrate into the gap between the upper and lower edges of the arc angle steel 17. During the rotation of the rotating head 37, the scraper 36 processes the burrs and oxide layers in the gap.

[0027] Working principle: Place the curved angle steel 17 to be polished in the clamping mechanism. The pneumatic push rod 16 drives the chuck 18 to press against the ends of the curved angle steel 17 from both sides to achieve horizontal fixation. The second hydraulic cylinder 12 pushes the support plate 11 to lift the curved angle steel 17 from below to adapt to the stable support of workpieces with different curvatures. After the curved angle steel 17 is fixed; The Z-axis drive mechanism 3 adjusts the height of the slide 15, and the X-axis drive mechanism 6 controls the horizontal movement of the slide 5 so that the frame 8 covers the area of ​​the arc angle steel 17 to be polished. The first hydraulic cylinder 7 can fine-tune the vertical position of the frame 8 at the front end. The two-way telescopic rod 19 drives the L-shaped seats 23 on both sides to move toward each other, driving the fixed block 31 to approach the planes on both sides of the arc angle steel 17. Driven by the X-axis drive mechanism 6, the spring 24 pushes the telescopic cylinder 25 to slide along the outside of the fixed rod 21, so that the bevel grinding head 32 on the outer surface of the front end of the fixed block 31 always elastically presses the arc angle steel 17. The surface of the angle steel 17 adapts to the arc shape change, efficiently peels off the oxide scale and polishes it. The cylinder 38 pushes the slide 28 downward, and the motor 29 drives the shaft 33 to drive the rotating head 37 to rotate at high speed. The cross diamond crusher 35 can crush the bulge in the plane area of ​​the arc angle steel 17. At the same time, multiple groups of scrapers 36 arranged on the outer circumference can scrape off the curling and burrs. In the process of the cylinder 38 pushing, the gaps in the arc angle steel 17 are processed in all directions. At the same time, when the shaft 33 rotates, the chip blower 34 rotates to generate airflow, which can blow the debris away from the processing area. After polishing is completed, the bidirectional telescopic rod 19 expands the reset fixed block 31, the cylinder 38 lifts the turning mechanism, the pneumatic push rod 16 retracts to release the workpiece, the polished arc angle steel 17 is taken out, and the various mechanisms of the equipment return to their original positions.
