Description

Technical Field

[0001] This invention relates to the field of sheet metal cleaning technology, specifically to a water washing module and water washing process. Background Technology

[0002] All components of mining vehicles require electrophoresis treatment before assembly to improve paint adhesion. U-shaped sheet metal parts are one of the commonly used components in mining vehicles, and electrophoresis treatment is usually performed by hanging because the contact area between the hook and the U-shaped sheet metal part is small, thus reducing the blind zone of electrophoresis treatment.

[0003] Before electrophoresis, the U-shaped sheet metal parts need to be washed with water (including torrent rinsing and immersion cleaning) to remove impurities such as iron filings and dust from their surface.

[0004] In traditional flood washing techniques, several U-shaped sheet metal parts are typically suspended in a ring within a washing tank. Water pipes are installed on the inner wall of the tank, spraying water onto the U-shaped parts. However, the water flow is directed from the inner wall towards the center of the tank, resulting in a situation where the surfaces of the U-shaped parts closest to the inner wall are easily cleaned, while the surfaces facing away from the inner wall are difficult to clean (i.e., there are blind spots on the surfaces of the U-shaped parts facing the center of the tank). Furthermore, the surfaces within these blind spots lack pre-wetting (from the flood wash), making them difficult to clean during immersion washing as well. Summary of the Invention

[0005] In order to overcome the problem in the above-mentioned background technology that "the surface of the U-shaped sheet metal parts facing the center of the rinsing pool is difficult to clean", the present invention provides a water washing module and a water washing process.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] The water washing module includes a flood flushing pool, with several vertically positioned second water supply pipes located on the inner wall of the flood flushing pool; nozzles for spraying water onto the U-shaped sheet metal parts are located on the side walls of the second water supply pipes; the second water supply pipes include a central water supply pipe and side water supply pipes, with the central water supply pipe located in the middle of the inner wall of the flood flushing pool and the side water supply pipes located on both sides of the central water supply pipe; it also includes a hanging frame, which includes an upper rectangular frame that can be adapted to the position of the flood flushing pool, and the U-shaped sheet metal parts are suspended below the first right angle portion of the upper rectangular frame; the upper rectangular frame A reflective roller is provided at the lower center of the frame; the outer wall of the reflective roller is provided with a reflective surface; the water jet from the side water supply pipe directly impacts the surface of the U-shaped sheet metal part facing away from the reflective roller; the water jet from the central water supply pipe is reflected by the reflective surface and then impacts the surface of the U-shaped sheet metal part facing the reflective roller; the water jet from the central water supply pipe impacts the reflective surface to form a reflected water flow; the reflective roller can rotate to reflect the reflected water flow to different positions of the U-shaped sheet metal part, causing the U-shaped sheet metal part to shake and / or rotate when being rinsed.

[0008] As a further optimization of the present invention, the water jet from the central water supply pipe is perpendicular to the inner wall of the flood flushing pool.

[0009] As a further optimization of the present invention, the outer wall of the reflective roller is provided with an extended paddle; when the reflective roller rotates, the extended paddle can push the U-shaped sheet metal part to sway and / or rotate.

[0010] As a further optimization of the present invention, a first X-shaped frame is fixedly installed on the inner side of the upper rectangular frame; a first motor for driving the reflective roller to rotate is installed above the middle part of the first X-shaped frame.

[0011] As a further optimization of the present invention, it also includes an immersion cleaning tank, which is filled with cleaning fluid; when the U-shaped sheet metal part is immersed below the surface of the cleaning fluid, the reflective roller can rotate to agitate the cleaning fluid.

[0012] As a further optimization of the present invention, the extended paddle has an arc-shaped plate structure and the opening direction of the inner cavity is oriented in the direction of rotation of the reflective roller; when the reflective roller is immersed in the cleaning fluid and rotates, it can form a C-shaped water flow on the front side of the rotation direction of the extended paddle; the C-shaped water flow can push the U-shaped sheet metal part outward in advance to reduce the impact force between the extended paddle and the U-shaped sheet metal part.

[0013] As a further optimization of the present invention, the hanging frame further includes a lower rectangular frame and upright support rods; the lower rectangular frame is located below the upper rectangular frame, and the first right-angle portion of the upper rectangular frame is adapted to the second right-angle portion of the lower rectangular frame; the upper rectangular frame includes four top support crossbars connected end to end, and the lower rectangular frame includes four bottom support crossbars connected end to end; the top end of the upright support rod is perpendicularly connected to the top support crossbar at 3 / 4 of its length, and the bottom end is perpendicularly connected to the bottom support crossbar at 3 / 4 of its length, to make way for the hanging space located below the first right-angle portion; the upright support rods are provided in four and arranged in a circular array around the reflective roller.

[0014] As a further optimization of the present invention, a second X-shaped frame is fixedly installed on the inner side of the lower rectangular frame; the bottom end of the reflective roller is rotatably connected to the middle part of the second X-shaped frame.

[0015] As a further optimization of the present invention, a sealing fin plate is installed on the outer periphery of the upper rectangular frame. The sealing fin plate is used to block the reflected water flow that splashes outward through the gap between the upper rectangular frame and the flood flushing pool.

[0016] The water washing process, which involves washing the U-shaped sheet metal part using the aforementioned water washing module, includes the following steps: S1, placing the U-shaped sheet metal part in the inner cavity of the flood rinsing tank for flood rinsing; during this process, the water jets from the side water supply pipes directly impact the surface of the U-shaped sheet metal part facing away from the reflective roller; the water jets from the central water supply pipes, after being reflected by the reflective surface, impact the surface of the U-shaped sheet metal part facing the reflective roller, while the reflective roller rotates, causing the outer extension paddle to push the U-shaped sheet metal part to sway and / or rotate; S2, placing the U-shaped sheet metal part in the inner cavity of the immersion cleaning tank for immersion cleaning; during this process, the reflective roller rotates, causing the C-shaped water jets to first push the U-shaped sheet metal part outward and / or rotate, and then the outer extension paddles collide with the U-shaped sheet metal part.

[0017] In summary, the present invention has at least one of the following advantages:

[0018] (1) In this invention, the reflective roller is placed at the center of the inner cavity of the flood flushing pool; at this time, the surface of the U-shaped sheet metal part facing the inner wall of the flood flushing pool (i.e. the surface facing away from the center of the flood flushing pool) is directly flushed by water from the side water supply pipe, and the water sprayed from the central water supply pipe is reflected by the reflective surface and sprayed onto the surface of the U-shaped sheet metal part facing away from the inner wall of the flood flushing pool (i.e. the surface facing the center of the flood flushing pool), thereby reducing the blind spot of flushing, realizing pre-wetting, and thus improving the cleaning effect.

[0019] (2) The U-shaped sheet metal parts can shake and / or rotate when being rinsed, thereby increasing the impact area between the U-shaped sheet metal parts and the water flow, avoiding single-point rinsing, and improving the rinsing effect.

[0020] (3) If the reflective roller can rotate synchronously with the reflective surface, the angle between the water flow sprayed through the central water supply pipe and the reflective surface will change dynamically. The position and angle of the reflected water flow impacting the U-shaped sheet metal part will change dynamically. On the one hand, it directly increases the rinsing area of ​​the U-shaped sheet metal part and the reflected water flow (improves the rinsing cleanliness), and on the other hand, it pushes the U-shaped sheet metal part to shake and / or rotate.

[0021] (4) Since the direction of the water flow sprayed through the side water supply pipe is fixed, the U-shaped sheet metal part will shake and / or rotate when it is rinsed. The impact position of the water flow with the fixed spray direction and the U-shaped sheet metal part will move, and the corresponding rinsing area will increase, thus improving the rinsing cleanliness.

[0022] (5) The outer wall of the reflective roller is provided with an extended blade. On the one hand (during torrent flushing), the extended blade directly contacts the U-shaped sheet metal part and pushes it to shake and / or rotate; on the other hand (during immersion cleaning), the extended blade can agitate the cleaning fluid, thereby increasing the relative flow speed between the cleaning fluid and the U-shaped sheet metal part, and thus improving the cleaning cleanliness.

[0023] (6) The extended paddle has an arc-shaped plate structure, and the opening direction of its inner cavity points in the direction of rotation of the reflective roller. The cross-section of the extended paddle is C-shaped. When the reflective roller is immersed in the cleaning fluid and rotates, it can shear the cleaning fluid originally located in the side groove, thereby forming a C-shaped water flow on the front side of the rotation direction of the extended paddle. The C-shaped water flow plays a buffering role between the extended paddle and the U-shaped sheet metal part, thereby reducing the impact damage to the U-shaped sheet metal part, reducing scratches, and improving product quality.

[0024] (7) Due to the pre-push effect of the C-shaped water flow, the U-shaped sheet metal part has a certain initial kinetic energy (i.e., it is in a rotating state) before it collides with the outer extension plate; when the U-shaped sheet metal part collides with the outer extension plate, the rotation directions of the two are opposite, and the linear velocity of the contact parts of the two is the same, which can achieve the unloading effect, reduce the impact damage to the U-shaped sheet metal part, reduce scratches, and improve product quality.

[0025] (8) The C-shaped water flow acts as a buffer between the extension blade and the U-shaped sheet metal part. On the one hand, it avoids the problem of the elastic protective layer being damaged by cutting and failing. On the other hand, it avoids cutting debris, thereby avoiding the contamination of the solution in subsequent pickling, neutralization, electrophoresis and other steps. Attached Figure Description

[0054] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows:

[0055] Reference Figures 1-3This embodiment provides a water washing module, including a flood flushing tank 1, which is a four-sided box structure with an open top and a sealed bottom. The cross-section of the inner cavity of the flood flushing tank 1 is rectangular or square. A first water supply pipe 11 and a second water supply pipe 12 are provided on the inner side wall of the flood flushing tank 1; the first water supply pipe 11 is horizontally placed at the bottom of the inner side wall of the flood flushing tank 1, and the bottom surface of the first water supply pipe 11 is pressed against the bottom surface of the inner cavity of the flood flushing tank 1 (that is, the bottom surface of the inner cavity of the flood flushing tank 1 provides upward support to the first water supply pipe 11, avoiding the problem of the first water supply pipe 11 bending and deforming due to the weight of the second water supply pipe 12). The first water supply pipe 11 is horizontally placed along the boundary line between the bottom surface of the inner cavity and the inner side wall of the flood flushing tank 1.

[0056] Reference Figures 1-3 The second water supply pipe 12 has several sections arranged in a straight array at equal intervals along the axial direction of the first water supply pipe 11. The second water supply pipe 12 is vertical and its bottom end is connected to and communicates with the first water supply pipe 11 (for example, through a T-joint). The side wall of the second water supply pipe 12 is provided with nozzles 121 for spraying water flow 120 onto the U-shaped sheet metal part 4. The nozzles 121 are inserted into the outlet of the side wall of the second water supply pipe 12 and are sealed and fixed (for example, through heat fusion). The bottom of the first water supply pipe 11 passes through the side wall of the flood flushing pool 1 and is connected to an external water pump. The external water pump is connected to an external water source (for example, a water storage tank) through an external water supply pipe. The external water pump can pressurize the cleaning water (located in the water storage tank) into the first water supply pipe 11 and the second water supply pipe 12. The cleaning water is pressurized and sprayed out through the nozzles 121 to form water flow 120.

[0057] Reference Figures 3-6 The second water supply pipe 12 is connected to the inner wall of the flood flushing pool 1 via a pipe clamp assembly 13. The pipe clamp assembly 13 includes an n-shaped plate 131 and a U-shaped rod 132; the n-shaped plate 131 includes a first vertical plate 1311, a second vertical plate 1312, and a connecting top plate 1313 fixedly connected in an n-shape; the connecting top plate 1313 is horizontally placed, and its two side edges are respectively vertically fixedly connected to the top of the first vertical plate 1311 and the top of the second vertical plate 1312 (e.g., through an integral fixed connection). The first vertical plate 1311 is attached to and fixedly connected to the inner wall of the flood flushing pool 1 (e.g., through welding or through bolts and sealing rings); the second vertical plate 1312 is attached to the second water supply pipe 12. The U-shaped rod 132 is arranged horizontally and sleeved on the outer periphery of the second water supply pipe 12; the second vertical plate 1312 is provided with two first through holes 13121, and the two ends of the U-shaped rod 132 are respectively inserted into the two first through holes 13121 and pulled together by the pull nut 1321 (the end of the U-shaped rod 132 is connected to the pull nut 1321 by thread, and the pull nut 1321 is located below the connecting top plate 1313 and pressed against the side wall of the second vertical plate 1312 near the first vertical plate 1311).

[0058] Reference Figure 3 and Figure 12 The second water supply pipe 12 includes a central water supply pipe 12a and side water supply pipes 12b. The central water supply pipe 12a is located in the middle of the inner wall of the flood flushing pool 1, and the side water supply pipes 12b are located on both sides of the central water supply pipe 12a. Within the same inner wall area of ​​the flood flushing pool 1, at least two side water supply pipes 12b are provided on each side of the central water supply pipe 12a.

[0059] Reference Figure 1 A drain pipe 14 is connected to and connected to the lowest point of the bottom surface of the inner cavity of the flood flushing pool 1 (for example, by welding to achieve a sealed and fixed connection). After the water flow 120 impacts the U-shaped sheet metal part 4, it falls to the bottom surface of the inner cavity of the flood flushing pool 1 and is then discharged through the drain pipe 14.

[0060] Reference Figure 1 , Figure 2 and Figure 7 It also includes a hanging frame 3, which has a hanging space 330. The U-shaped sheet metal part 4 is suspended in the hanging space 330 of the hanging frame 3 by a second sling 41. The hanging frame 3 is located below the conveyor chain 2. The conveyor chain 2 is connected to the lifting assembly 21 (e.g., an electric hoist) by a chain. The lifting assembly 21 is connected to the hanging frame 3 by a first sling 22. The bottom end of the first sling 22 is provided with a first hook (e.g., a self-locking hook, which is a conventional existing technology in the industry, and the specific structure will not be described in detail).

[0061] Reference Figure 7 , Figure 8 and Figure 12 The hanging frame 3 includes an upper rectangular frame 31, which is rectangular or square in shape. The upper rectangular frame 31 can be fitted into the top of the inner cavity of the flood flushing pool 1 in a U-shape. The two adjacent inner sidewalls of the flood flushing pool 1 are perpendicular to each other and form a right angle structure at the connection position. The first right angle portion 3101 of the upper rectangular frame 31 is fitted into the right angle structure, and the four first right angle portions 3101 correspond one-to-one with the four right angle structures. The U-shaped sheet metal part 4 is suspended below the first right angle portion 3101. When the hanging frame 3 is placed into the inner cavity of the flood flushing pool 1, the U-shaped sheet metal part 4 can be as close as possible to the side water supply pipe 12b located at the right angle structure position.

[0062] Reference Figure 7The upper rectangular frame 31 includes four top support crossbars 311, which are connected end to end in a rectangular or upright shape. The ends of two adjacent top support crossbars 311 are vertically fixedly connected (e.g., by bolts, welding, or integral connection) to form a first right angle portion 3101. A second lifting lug 36 is welded or bolted to the lower surface of the first right angle portion 3101 (i.e., the lower surface of the top support crossbar 311).

[0063] Reference Figure 2 , Figure 7 and Figure 8 When there is only one U-shaped sheet metal part 4 under the same right angle, the U-shaped sheet metal part 4 is connected to the second lifting lug 36 through the second sling 41; that is, the top and bottom ends of the second sling 41 are respectively provided with second hooks (such as self-locking hooks, which are conventional existing technologies in the industry, and the specific structure will not be described in detail); the upper second hook is hung and connected to the second lifting lug 36, and the lower second hook is hung and connected to the mounting hole 40 at the sharp corner of the end of the U-shaped sheet metal part 4.

[0064] Reference Figure 2 , Figure 7 and Figure 9 When two or more U-shaped sheet metal parts 4 are located below the same right angle, the uppermost U-shaped sheet metal part 4 is connected to the second lifting lug 36 via the second suspension cable 41 (i.e., the second suspension cable 41 has a second hook at both ends; the upper hook is connected to the second lifting lug 36, and the lower hook is connected to the mounting hole 40 at the pointed end of the U-shaped sheet metal part 4). Adjacent U-shaped sheet metal parts 4 are suspended by a third suspension cable 42. The third suspension cable 42 has a third hook at both ends (e.g., a self-locking hook, which is standard technology in the industry; the specific structure will not be described in detail). The two third hooks are connected to the two adjacent U-shaped sheet metal parts 4 (mounting holes 40 at the pointed end), thus achieving the series suspension of multiple U-shaped sheet metal parts 4.

[0065] The second sling 41 and the third sling 42 are both chain structures, which have better rotational (and reverse rotational) and sway resistance (compared to steel wire ropes).

[0066] Reference Figure 7 , Figures 10-12A cylindrical reflective roller 37 is located below the center of the upper rectangular frame 31. The reflective roller 37 is vertically positioned and can rotate around the vertical axis of the upper rectangular frame 31. A reflective surface 371 is provided on the outer wall of the reflective roller 37, and the reflective surface 371 is parallel to the axis of the reflective roller 37. Four reflective surfaces 371 are arranged at equal intervals and angles on the outer wall of the reflective roller 37; adjacent reflective surfaces 371 are perpendicular to each other.

[0067] Reference Figure 12 The water jet 120 from the side water supply pipe 12b directly impacts the surface of the U-shaped sheet metal part 4 facing away from the reflective roller 37; the water jet 120 from the central water supply pipe 12a impacts the surface of the U-shaped sheet metal part facing the reflective roller 37 after being reflected by the reflective surface 371; thus solving the problem that the side wall of the U-shaped sheet metal part 4 near the center of the inner cavity of the flood flushing pool 1 cannot be flushed by the flood, thereby improving the comprehensiveness of flushing, reducing blind spots in flushing, and improving the washing effect.

[0068] Reference Figure 12 and Figure 13 The water jet 120 sprayed from the central water supply pipe 12a impacts the reflective surface 371, forming a reflected water jet 1200. The reflective roller 37 can rotate (the reflective surface 371 rotates synchronously with the reflective roller 37, specifically simultaneously, at the same speed, and in the same direction), that is, the angle between the reflective surface 371 and the inner wall of the flood flushing pool 1 changes, that is, the angle between the reflective surface 371 and the water jet 120 sprayed through the central water supply pipe 12a changes, which is used to reflect the reflected water jet 1200 to different positions of the U-shaped sheet metal part 4. (That is, the impact position between the reflected water flow 1200 and the U-shaped sheet metal part 4 changes, thereby improving the thoroughness of rinsing, reducing blind spots, and improving the washing effect.) This causes the U-shaped sheet metal part 4 to shake and / or rotate during rinsing (caused by the combined action of the reflected water flow 1200 and the water flow 120 sprayed through the side water supply pipe 12b; the direction of the reflected water flow 1200 changes, and combined with the weight of the U-shaped sheet metal part 4 and the influence of the upward pulling force, the U-shaped sheet metal part 4 is in an unstable stress state). Since the direction of the water flow 120 sprayed through the side water supply pipe 12b is fixed, the shaking and / or rotation of the U-shaped sheet metal part 4 during rinsing changes the impact position between the fixed-direction water flow 120 and the U-shaped sheet metal part 4, thereby improving the thoroughness of rinsing, reducing blind spots, and improving the washing effect.

[0069] Reference Figure 12 The water jet 120 from the central water supply pipe 12a is perpendicular to the inner wall of the (corresponding) flood flushing pool 1.

[0070] Reference Figure 10 and Figure 11The outer wall of the reflector roller 37 is provided with an extended paddle 372 (e.g., fixed by bolts or by an integral fixed connection); when the reflector roller 37 rotates, the extended paddle 372 can push the U-shaped sheet metal part 4 to shake and / or rotate (e.g., the end of the extended paddle 372 away from the reflector roller 37 impacts the U-shaped sheet metal part 4, thereby pushing the U-shaped sheet metal part 4 to shake and / or rotate). Similarly, the U-shaped sheet metal part 4 that shakes and / or rotates can move with the impact position of the water flow 120 / reflected water flow 1200, avoiding single-point rinsing, thereby improving the comprehensiveness of rinsing, reducing rinsing blind spots, and improving the washing effect.

[0071] Reference Figure 7 A first X-shaped frame 34 is fixedly installed on the inner side of the upper rectangular frame 31. The end of the first X-shaped frame 34 is fixedly connected to the end of the top support crossbar 311 (e.g., by bolts or by welding). A first motor 38 for driving the reflector roller 37 to rotate is installed above the middle of the first X-shaped frame 34. The first motor 38 is vertically arranged; the output shaft of the first motor 38 is inserted into the adapter hole in the middle of the first X-shaped frame 34, and a clearance is provided between the output shaft and the adapter hole to allow the output shaft to rotate smoothly; the housing of the first motor 38 is detachably connected to the first X-shaped frame 34 (e.g., by bolts); the output shaft of the first motor 38 is coaxially arranged with the top end of the reflector roller 37 and is detachably connected (e.g., by bolts).

[0072] Reference Figure 7 The hanging frame 3 also includes a lower rectangular frame 32 and a support rod 33. The lower rectangular frame 32 is located below the upper rectangular frame 31. The upper rectangular frame 31 and the lower rectangular frame 32 are the same size and arranged in a cuboid or cube shape. The first right-angle portion 3101 of the upper rectangular frame 31 is adapted to the second right-angle portion 3201 of the lower rectangular frame 32. The four first right-angle portions 3101 correspond one-to-one with the four second right-angle portions 3201. The second right-angle portion 3201 is located directly below the corresponding first right-angle portion 3101.

[0073] Reference Figure 7 The lower rectangular frame 32 includes four bottom support crossbars 321 connected end to end; the four bottom support crossbars 321 are spliced ​​into a rectangular or square shape; the ends of two adjacent bottom support crossbars 321 are vertically fixedly connected (e.g., by bolts or by welding). The connection position of the ends of two adjacent bottom support crossbars 321 forms a second right angle portion 3201.

[0074] Reference Figure 7 and Figure 10The top end of the upright support rod 33 is perpendicularly connected to the top support crossbar 311 at 3 / 4 of its length (e.g., by bolts or welding), and the bottom end is perpendicularly connected to the bottom support crossbar 321 at 3 / 4 of its length (e.g., by bolts or welding). This is to make way for the hanging space 330 located below the first right angle 3101 and to avoid structural conflict between the U-shaped sheet metal part 4 and the upright support rod 33. Four upright support rods 33 are arranged in a circumferential array with equal spacing and equal angles around the reflector roller 37.

[0075] The upright support rod 33 is located at the non-center part of the top support crossbar 311 / the non-center part of the bottom support crossbar 321 to make way for the water flow 120 sprayed from the central water supply pipe 12a.

[0076] Reference Figure 7 A second X-shaped frame 3202 is fixedly installed on the inner side of the lower rectangular frame 32. The end of the second X-shaped frame 3202 is fixedly connected to the end of the bottom support crossbar 321 (e.g., by bolts or by welding). The center of the second X-shaped frame 3202 is located directly below the center of the first X-shaped frame 34; the bottom end of the reflector roller 37 is detachably and rotatably connected to the center of the second X-shaped frame 3202.

[0077] Reference Figure 7 A detachable insertion shaft (e.g., detachably connected by bolts) is installed at the center of the bottom surface of the reflector roller 37, and the insertion shaft is coaxial with the reflector roller 37. A positioning hole is provided at the center of the second X-shaped frame 3202, into which the insertion shaft can be inserted and connected to the bottom surface of the reflector roller 37. During the rotation of the reflector roller 37, the positioning hole can apply a lateral limiting force to the bottom end of the reflector roller 37, thereby improving the rotational stability of the reflector roller 37. A clearance is provided between the positioning hole and the insertion shaft to allow the insertion shaft to rotate smoothly.

[0078] Reference Figure 14 A sealing fin plate 39 is fitted around the outer periphery of the upper rectangular frame 31. The outer wall of the upper rectangular frame 31 is fitted and sealed to the inner edge of the sealing fin plate 39 (e.g., through welding). The sealing fin plate 39 is U-shaped. The sealing fin plate 39 is used to seal the gap between the upper rectangular frame 31 and the flood flushing pool 1; that is, when the first sling 22 lowers the upper rectangular frame 31, it can press the sealing fin plate 39 against the top of the flood flushing pool 1, thereby preventing the reflected water flow 1200 from splashing out through the gap between the upper rectangular frame 31 and the flood flushing pool 1, reducing water waste. At the same time, the sealing fin plate 39 can apply a horizontal limiting force to the upper rectangular frame 31, preventing the upper rectangular frame 31 from swinging and causing the water flow 120 to misalign with the reflective roller 37 (i.e., the water flow 120 cannot impact the reflective roller 37).

[0079] Reference Figure 15 The water washing module also includes an immersion cleaning tank 5, which contains a cleaning solution, namely water. When the U-shaped sheet metal part 4 is immersed below the surface of the cleaning solution, the reflective roller 37 can rotate to agitate the cleaning solution using the extended paddle 372, causing the cleaning solution to flow and relative to the U-shaped sheet metal part 4, thereby improving the cleaning effect on the U-shaped sheet metal part 4.

[0080] Reference Figure 15 The extended paddle 372 has an arc-shaped plate structure, and the opening direction of its inner cavity points in the direction of rotation of the reflective roller 37. The opening direction of the extended paddle 372 points towards the adjacent side groove 370. The extended paddle 372 is located at the sharp corner position formed by adjacent reflective surfaces 371. The cross-section of the extended paddle 372 is C-shaped. When the reflective roller 37 rotates while immersed in the cleaning fluid, (the end of the inner surface of the extended paddle 372 near the reflective roller 37 can shear the cleaning fluid (originally) located in the side groove 370) a C-shaped water flow 12000 can be formed on the front side of the rotation direction of the extended paddle 372, and the C-shaped water flow 12000 flows away from the reflective roller 37. The C-shaped water flow 12000 can pre-push the U-shaped sheet metal part 4 outward (i.e., away from the reflector roller 37) to reduce impact damage to the U-shaped sheet metal part 4 (the C-shaped water flow 12000 can act as a buffer between the extended paddle 372 and the U-shaped sheet metal part 4). The extended paddle 372 is radially arranged at the end of the reflector surface 371.

[0081] Reference Figure 15 The C-shaped water flow 12000 impacts the outer edge of the U-shaped sheet metal part 4, which can apply torque to the U-shaped sheet metal part 4; the extended paddle 372 impacts the outer edge of the U-shaped sheet metal part 4, which can apply torque to the U-shaped sheet metal part 4; thereby causing the U-shaped sheet metal part 4 to rotate.

[0082] Reference Figure 15 Due to the pre-push effect of the C-shaped water flow 12000, the U-shaped sheet metal part 4 has a certain initial kinetic energy before colliding with the outer extension plate 372 (i.e., it is in a rotating state, and the rotation direction of the U-shaped sheet metal part 4 is opposite to the rotation direction of the reflective roller 37). When the U-shaped sheet metal part 4 collides with the outer extension plate 372, the rotation directions of the two are opposite, and the linear velocity of the contact position of the two is the same, which can achieve the force relief effect and reduce the impact damage (from the outer extension plate 372) to the U-shaped sheet metal part 4.

[0083] In conventional technology, an elastic protective layer (e.g., a rubber layer, fixedly connected by bolts) is fixedly provided on the side edge surface of the extended paddle 372 away from the reflective roller 37. When the extended paddle 372 impacts the U-shaped sheet metal part 4, the elastic protective layer acts as a buffer between the two, thereby reducing the impact damage (from the extended paddle 372) to the U-shaped sheet metal part 4. However, the U-shaped sheet metal part 4 usually has sharp edges. If these sharp edges frequently impact the elastic protective layer, they will cut it. The elastic protective layer will be frequently cut at different angles, causing local detachment (the elastic protective layer is strip-shaped and normally vertically positioned, but the U-shaped sheet metal part 4 will shake and / or rotate, so the angle between the sharp edge and the elastic protective layer and the position of mutual impact are not fixed). Furthermore, the sharp edge and the elastic protective layer usually impact in an X-shape, with a relatively small force-bearing area, increasing local pressure, enhancing the cutting effect, and making the elastic protective layer more susceptible to damage, leading to the exposure of the extended paddle 372, thus causing the protection to fail. The present invention uses a C-shaped water flow 12000 to act as a buffer between the outer extension blade 372 and the U-shaped sheet metal part 4, which can avoid the generation of cutting debris (cutting debris is usually rubber debris, which floats on the surface of the cleaning solution and is difficult to sink to the bottom. Therefore, during the extraction process on the U-shaped sheet metal part 4, the cutting debris will adhere to the surface of the U-shaped sheet metal part 4 or get stuck in the holes of the U-shaped sheet metal part 4 due to the surface tension of the water, thus contaminating the chemical solutions in subsequent pickling, neutralization, electrophoresis and other steps).

[0084] The washing module also includes an overhead conveyor and an overhead frame. The overhead frame is installed on the workshop floor. The flood rinsing tank 1 and the immersion cleaning tank 5 are arranged in a straight line on the ground below the overhead frame; the overhead conveyor is installed on the overhead frame; the overhead conveyor is connected to the conveyor chain 2, which is arranged along the layout direction of the flood rinsing tank 1 and the immersion cleaning tank 5. The overhead conveyor is used to drive the conveyor chain 2, the lifting assembly 21, and the overhead frame 3 to move laterally, for example, moving the overhead frame 3 from above the flood rinsing tank 1 to above the immersion cleaning tank 5.

[0085] Combination Figure 1 The lifting assembly 21 can retract and extend the first sling 22, thereby driving the hanging frame 3 to move vertically (for example, lowering the hanging frame 3 and the U-shaped sheet metal part 4 into the flood cleaning tank / immersion cleaning tank 5 or lifting them upward from the inner cavity of the flood cleaning tank / immersion cleaning tank 5).

[0086] Reference Figure 15 and Figure 16 The opening direction of the extended lever 372 is set in a clockwise direction (clockwise when viewed from above, with the reflector roller 37 as the center). (See reference...) Figure 16When flushed within the floodwaters 1, the reflector roller 37 can rotate counterclockwise (counterclockwise from a top-down view, centered on the reflector roller 37; low speed, e.g., 1 revolution / minute) to cause the arc surface of the outer wall of the extended tab 372 to impact the U-shaped sheet metal part 4, thus reducing impact damage (if the end face of the extended tab 372, away from the reflector roller 37, impacts the U-shaped sheet metal part 4, it will cause more severe scratches). (Refer to...) Figure 15 When immersed in the cleaning tank 5, the reflective roller 37 can rotate clockwise (clockwise in the top view with the reflective roller 37 as the center; low speed rotation, for example 1 revolution / minute) to make the extended blade 372 spin cut (located in the side groove 370 and has inertia) the cleaning fluid to form a C-shaped water flow 12000.

[0087] The U-shaped sheet metal part 4 is a U-shaped plate structure; when suspended, the U-shaped sheet metal part 4 is vertically arranged in a C-shape, and it has an inner cavity with top and bottom sealing and three side openings.

[0088] Reference Figure 15 If the opening direction of the U-shaped sheet metal part 4 is set in a counterclockwise direction (with the reflective roller 37 as the center, it is counterclockwise in the top view), then the C-shaped water flow 12000 will pass through the inner cavity of the U-shaped sheet metal part 4 (along its opposite side opening). In this case, the C-shaped water flow 12000 will have difficulty effectively transmitting the impact force to the U-shaped sheet metal part 4, so the buffering effect will be greatly weakened.

[0089] To avoid the above problems, refer to Figure 17 In this invention, the opening direction of the U-shaped sheet metal part 4 is set in a clockwise direction (clockwise in the top view with the reflective roller 37 as the center), that is, the back (normal) of the U-shaped sheet metal part 4 points in a counterclockwise direction (counterclockwise in the top view with the reflective roller 37 as the center); then the outer end of the C-shaped water flow 12000 can directly impact the back of the U-shaped sheet metal part 4 (and impact along its normal direction), so as to increase the impact force from the C-shaped water flow 12000 on the U-shaped sheet metal part 4, thereby improving the buffering effect and reducing impact damage.

[0090] Reference Figure 18 The second slings 41 and the third slings 42 are arranged in pairs to restrict the opening orientation of the U-shaped sheet metal part 4. The two pairs of second slings 41 are used to suspend the same U-shaped sheet metal part 4 (at two right-angled positions on the same end); the two pairs of third slings 42 are used to suspend the same U-shaped sheet metal part 4 (at two right-angled positions on the same end); to restrict the opening orientation of the U-shaped sheet metal part 4 (double-sling suspension has a better limiting effect than single-sling suspension).

[0091] Reference Figure 19The two pairs of second slings 41 are arranged in a figure-eight shape; that is, the distance between their top ends is smaller than the distance between their bottom ends, thereby restricting the orientation of the opening of the U-shaped sheet metal part 4 while improving the rotation capability of the U-shaped sheet metal part 4 (that is, taking into account both a certain directionality and a certain rotation capability), which is used to enhance the uniformity of cleaning.

[0092] Reference Figure 20 The upright support rod 33 (connected to the same top support crossbar 311) and the second sling 41 (top) are respectively located at both ends (not the same end) of the top support crossbar 311, to adapt and restrict the opening orientation and back orientation of the U-shaped sheet metal part 4.

[0093] The invention also includes an electrical cabinet, which is bolted to the floor of the processing workshop. The external water pump, electric hoist, first motor 38, and overhead conveyor are connected to the electrical cabinet via wires and signal lines. The electrical cabinet is also connected to the external power supply and external controller (e.g., a computer or PLC programmable logic controller) via wires and signal lines. The external controller controls the start-stop and other operating states of the external water pump, electric hoist, first motor 38, and overhead conveyor through the electrical cabinet.

[0094] The first motor 38 is a controllable motor (such as a servo motor or a stepper motor). By inputting electrical signals to the controllable motor through an external controller, the speed and start / stop timing of the controllable motor can be controlled.

[0095] The water washing process, which involves using a water washing module to wash the U-shaped sheet metal part 4, includes the following steps:

[0096] S1. The U-shaped sheet metal part 4 is placed in the inner cavity of the flood flushing pool 1 for flood flushing; during the process, the water jet 120 sprayed from the side water supply pipe 12b directly impacts the surface of the U-shaped sheet metal part 4 facing away from the reflective roller 37; the water jet 120 sprayed from the central water supply pipe 12a is reflected by the reflective surface 371 and then impacts the surface of the U-shaped sheet metal part 4 facing the reflective roller 37. At the same time, the reflective roller 37 rotates, causing the outer extension paddle 372 to push the U-shaped sheet metal part 4 to shake and / or rotate. During the rotation of the reflective surface 371, the reflected water jet 1200 can be reflected to different positions on the surface of the U-shaped sheet metal part 4, thereby driving the U-shaped sheet metal part 4 to shake and / or rotate.

[0097] S2. Place the U-shaped sheet metal part 4 into the inner cavity of the immersion cleaning tank 5 for immersion cleaning; during the process, the reflective roller 37 rotates, so that the C-shaped water flow 12000 first pushes the U-shaped sheet metal part 4 outward and / or rotates, and then the outer extension paddle 372 collides with the U-shaped sheet metal part 4.

[0098] The present invention has a simple structure and reliable function. The hanging frame 3 can be placed in the middle of the inner cavity of the flood flushing pool 1, so the reflective roller 37 is placed in the center of the inner cavity of the flood flushing pool 1. At this time, the surface of the U-shaped sheet metal part 4 facing the inner wall of the flood flushing pool 1 (i.e. the surface facing away from the center of the flood flushing pool 1) is directly flushed by the water flow 120 from the side water supply pipe 12b. The water flow 120 sprayed from the central water supply pipe 12a is reflected by the reflective surface 371 and sprayed onto the surface of the U-shaped sheet metal part 4 facing away from the inner wall of the flood flushing pool 1 (i.e. the surface facing the center of the flood flushing pool 1), thereby reducing the flushing blind area, realizing pre-wetting, and thus improving the cleaning effect.
