Description

Technical Field

[0001] The invention relates to the technical field of galvanizing processing, and in particular to a hot-dip galvanizing surface quality optimization processing device. Background Art

[0002] Hot-dip galvanizing is a metal anti-corrosion process in which steel products are immersed in molten zinc liquid to form a layer of zinc on the surface. The conventional galvanizing process is to lift square tubes or similar products into a galvanizing tank filled with heated liquefied galvanizing liquid for immersion galvanizing.

It also lacks the turnover galvanizing function. 2. The adhesion effect of immersion alone is limited, and it is inconvenient to pressurize the galvanized surface; 3. The lifting and movement control is inconvenient, and there is a lack of multi-axis mobile galvanized structure that can be used for products of different sizes. Summary of the Invention

The first motor 102 is transmission-connected to the first screw 101; the first screw 101 is threadedly connected to the longitudinal slide 2; the first motor 102 is a servo motor.

[0021] Among them, a second screw 301 is arranged at the bottom of the horizontal connecting seat 3 for horizontal rotation, and a second motor 302 is fixedly arranged on one side of the horizontal connecting seat 3. The second motor 302 is transmission-connected to the second screw 301, and the second screw 301 is threadedly connected to the transverse seat 5; the second motor 302 is a servo motor.

[0022] Among them, two groups of second electric cylinders 303 are fixedly arranged on both sides of the top of the horizontal connecting seat 3, and the telescopic ends of the second electric cylinders 303 are fixedly connected to a group of transverse hanging seats 4 respectively; a vertical guide rod 304 is fixedly arranged on the top of the horizontal connecting seat 3, and the vertical guide rod 304 is transmission-connected to the longitudinal slide 2.

[0027] like Figure 1-8 As shown, during operation, the first motor 102 is started by program control, driving the first screw 101 to rotate, and the first screw 101 drives the longitudinal slide 2 to move forward to a position aligned with the positioning mold base 6, and then the first electric cylinder 201 is extended to lower the transverse connecting seat 3, and at the same time the transverse hanging seat 4 is lowered, and the bearing round pile 405 is lowered to a height aligned with the two ends of the square tube, and then the second electric cylinders 303 on both sides are started to perform the extension action, bringing the two side rotating seats 404 closer together, and inserting the bearing round pile 405 into the square tube; Then, the first electric cylinder 201 is retracted to raise the transverse connecting seat 3, thereby raising the square tube. The first motor 102 is then reversed to move the longitudinal slide 2 backward to a position aligned with the galvanizing bath 7. The transverse connecting seat 3 is then lowered to immerse the lowermost end face of the square tube in the galvanizing solution for hot-dip galvanizing. The third motor 403 is then started at a fixed time to drive the linkage shaft 402 to rotate. The linkage shaft 402 cooperates with the bevel gear to drive the swivel seat 404 and the bearing round pile 405 to rotate. The swivel seat 404 rotates 90 degrees each time. like Figure 7 In the state, the square tube is rotated 90 degrees by the bearing round pile 405, so that the lowermost surface of the square tube can be replaced, and then the ungalvanized surface can be galvanized; Only the lowermost side of the square tube is galvanized to avoid galvanizing the linkage shaft 402 and the swivel seat 404. The bearing round pile 405 will be partially stained with the galvanizing liquid. It can be cleaned regularly and made of a material that is not easily stained with the galvanizing liquid.

[0028] Example 2: Based on Example 1, after galvanizing is completed, the third electric cylinder 501 can be started to drive the connecting frame 503 to descend, and the pressure roller 506 can be lowered to contact the uppermost surface of the square tube to squeeze the galvanized surface. The second motor 302 drives the second lead screw 301 to rotate, and the traverse seat 5 is moved laterally. The pressure roller 506 can be used to completely press the uppermost surface of the square tube; by pressing the galvanized surface, the quality can be optimized, and the number of presses can be set as needed. After compaction, it can be galvanized again, and it can be compacted again. Repeated galvanizing increases the adhesion effect of the galvanizing liquid.

[0029] Example 3: Based on Example 1, an infrared sensor is used to monitor the liquid level. When the liquid level drops, the liquid material is replenished and heated to continue working. An automatic adding device can be set up in conjunction with a control program to maintain the liquid level of the galvanizing solution.

[0030] Specific usage and function of this embodiment: In the present invention, when in use, the square tube to be galvanized is placed in the top through groove of the positioning die holder 6, manually aligned, and the surface garbage of the square tube is cleaned; The first motor 102 is started under program control, driving the first screw 101 to rotate. The first screw 101 drives the longitudinal slide 2 to move forward to a position aligned with the positioning mold base 6. Then, the first electric cylinder 201 is extended to lower the transverse connecting base 3. At the same time, the transverse hanging base 4 is lowered, and the load-bearing round pile 405 is lowered to a height aligned with the two ends of the square tube. Then, the second electric cylinders 303 on both sides are activated to perform the extension action, bringing the two side rotating bases 404 closer together, and inserting the load-bearing round pile 405 into the square tube. Then, the first electric cylinder 201 is retracted to raise the horizontal connecting seat 3, and the square tube can be raised. Then, the first motor 102 is reversed to move the longitudinal slide 2 backward to a position aligned with the galvanizing pool 7, and then the horizontal connecting seat 3 is lowered to immerse the lower end face of the square tube in the galvanizing solution for hot-dip galvanizing. Then, the third motor 403 is started at a fixed time to drive the linkage shaft 402 to rotate. The linkage shaft 402 cooperates with the bevel gear to drive the swivel seat 404 and the bearing round pile 405 to rotate. The swivel seat 404 rotates 90 degrees each time. Figure 7 The state of the square tube is made to rotate 90 degrees by the supporting pile 405, so that the lowermost surface of the square tube can be replaced, and the ungalvanized surface can be galvanized; After galvanizing is completed, the third electric cylinder 501 can be started to drive the connecting frame 503 to descend, and the pressure roller 506 can be lowered to contact the uppermost surface of the square tube to squeeze the galvanized surface. The second motor 302 drives the second lead screw 301 to rotate, and the traverse seat 5 is moved laterally. The uppermost surface of the square tube can be completely pressed by the pressure roller 506. After compaction, galvanizing can be carried out again, and then compaction can be repeated. Repeated galvanizing increases the adhesion effect. Since different square tubes have dimensional errors, different pressure rollers 506 are used in conjunction with different spring rods 504 to provide forces, which can ensure that the pressure rollers 506 are respectively in contact with the upper surfaces of a group of square tubes. After galvanizing is completed, the square tube is placed back on the top of the positioning die base 6 and can be unloaded; An infrared sensor is used to monitor the liquid level. When the liquid level drops, the liquid can be added and heated to continue working.
