Description

Technical Field

[0001] The utility model relates to the technical field of welding slag collection, in particular to a welding slag collection device for submerged arc welding processing. Background Art

[0002] Submerged arc welding is an automated arc welding process, which is characterized by the welding area being covered or buried in flux, thereby preventing air from polluting the welding area. Submerged arc welding is often used to weld thicker metal workpieces, such as shipbuilding, bridge construction, pressure vessel manufacturing and other fields. Due to its high efficiency and high quality, submerged arc welding is widely used in industrial production. During the welding process, flux is used, and the flux will adhere to the welding slag produced by welding and fall on the machine. In order to prevent the residue from affecting subsequent work, the flux and welding slag need to be cleaned in time, and the excess flux and welding slag need to be separated so that the flux can be reused.

[0034] Reference Figure 2 , Figure 3 The rear surface of the buckle 1 51 is fixedly connected to the front surface of the support platform 4. The buckle 1 51 is divided into two parts, one part is fixed to the front surface of the support platform 4, and the other part is fixed to the front surface of the collection box 52. The two parts can be locked with each other. There are multiple groups of buckles 1 51, and the multiple groups of buckles 1 51 are symmetrically distributed front and back with the center line of the support platform 4. The left surface of the buckle 2 54 is fixedly connected to the right surface of the collection box 52.

[0035] Reference Figure 2 , Figure 4 and Figure 5 The screening assembly includes a positioning ring 63, which is elastically connected to a filter plate 61 through a compression spring 62. A circular hole is provided on the upper surface of the filter plate 61. There are multiple groups of circular holes, which are distributed in a row on the upper surface of the filter plate 61. A smaller volume of welding flux can pass through, but a larger volume of welding slag cannot pass through the circular holes. A baffle 66 is fixedly connected to the lower surface of the filter plate 61. The lower surface of the baffle 66 is lower than the upper surface of the drawer 53. A protective block 64 is fixedly connected to the inner wall of the bottom end of the collection box 52. A motor 65 is provided on the inner wall of the top end of the protective block 64.

The filter plate 61 is slidably connected to the inner wall of the collection box 52, and the left surface of the baffle 66 is set as an inclined surface. When the drawer 53 is pulled out, the drawer 53 will squeeze the inclined surface of the baffle 66, and the baffle 66 will move upward to release the obstruction to the drawer 53. The output shaft of the motor 1 65 passes through the upper surface of the protective block 64.

[0037] Reference Figure 1 , Figure 6 The cleaning assembly includes a support block 71. A motor 2 72 is provided on the left surface of the support block 71. Starting the motor 2 72 will drive the reciprocating screw 73 to rotate. The output shaft of the motor 2 72 is fixedly connected to the reciprocating screw 73. The reciprocating screw 73 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The reciprocating screw 73 has self-locking properties. The outer wall of the reciprocating screw 73 is threadedly connected to a positioning plate 74. When the reciprocating screw 73 rotates, it will drive the positioning plate 74 to reciprocate laterally. The upper surface of the positioning plate 74 penetrates and slides. There is a scraper 76, and when the positioning plate 74 moves, the scraper 76 will be driven to move. The scraper 76 will sweep the welding slag and flux on the upper surface of the support platform 4 into the collection box 52. The upper surface of the scraper 76 is fixedly connected with a handle 2 711 for easy grasping. The inner wall of the rear side of the positioning plate 74 is fixedly connected with a block 75. When the scraper 76 moves downward and contacts with the block 75, it will stop moving and its position will be limited. The inner wall of the positioning plate 74 is elastically connected to the limit block 78 through a limit spring 77. The limit block 78 can limit the scraper 76. The upper surface of the limit block 78 is fixedly connected with a shift block 79.

[0038] Reference Figure 1 , Figure 6 The left surface of the reciprocating screw rod 73 is rotatably connected to the right surface of the support block 71, and the output shaft of the motor 2 72 passes through the left surface of the support block 71. The upper surface of the limit block 78 is an inclined surface, which squeezes the upper surface of the limit block 78 and the limit block 78 will move backward. One end of the limit spring 77 is fixedly connected to the inner wall of the rear side of the positioning plate 74, and the other end of the limit spring 77 is fixedly connected to the rear surface of the limit block 78. When the limit block 78 moves backward, it will squeeze the limit spring 77 to produce a reaction force, and the limit block 78 is slidably connected to the inner wall of the positioning plate 74. The shift block 79 passes through and is slidably connected to the upper surface of the positioning plate 74. The shift block 79 is set in a T shape. The reciprocating screw rod 73 is provided with two groups, and the two groups of reciprocating screw rods 73 are symmetrically distributed front and back with the center line of the support platform 4.

[0039] Working principle: When in use, first move the device to the designated location and lock the universal wheel 2, then adjust the hydraulic telescopic rod 3 to raise the support platform 4 to a suitable height and start welding. During the welding process, welding slag will be generated, and the welding slag and excess flux will fall on the upper surface of the support platform 4. In order to prevent the residual flux and welding slag from affecting subsequent work, they need to be cleaned up in time.

[0040] When cleaning, first start motor 2 72, which will also drive the reciprocating screw 73 to rotate. The rotating reciprocating screw 73 will drive the positioning plate 74 to move back and forth horizontally, and the moving positioning plate 74 will drive the scraper 76 to move synchronously. The moving scraper 76 will sweep the welding slag and flux remaining on the upper surface of the support table 4 into the collection box 52. After the welding slag and flux on the upper surface of the support table 4 are cleaned, turn off motor 2 72, and in order to facilitate the subsequent recovery of the flux, the welding slag and flux need to be separated.

[0041] When separating, start the motor 65, the motor 65 will drive the connecting plate 67 to rotate, and the rotating connecting plate 67 will squeeze the inclined surface of the baffle 66. After the inclined surface of the baffle 66 is squeezed, it will drive the filter plate 61 to move upward, and the upward moving filter plate 61 will squeeze the compression spring 62 to generate a reaction force. Under the action of the reaction force of the compression spring 62, the filter plate 61 will shake up and down, and the shaking filter plate 61 will separate the welding slag and the flux, and the flux will fall into the drawer 53 through the round hole, and the welding slag will stay on the filter plate 61.

[0042] After the welding slag and the flux are separated, the buckle 2 54 is unlocked, and then the handle 1 55 is grasped to pull out the drawer 53 and pour out the flux in the drawer 53 and collect it for subsequent use. Then the drawer 53 is inserted into the collection box 52 and the buckle 2 54 is locked. After the locking is completed, the buckle 1 51 is unlocked to remove the collection box 52 from the support platform 4, and the welding slag on the filter plate 61 is poured out for centralized treatment, and then the collection box 52 is fixed to the support platform 4 with the buckle 1 51.

[0043] When the scraper 76 is damaged and needs to be replaced, the shift block 79 can be moved backward. The shift block 79 moving backward will drive the limit block 78 to move synchronously. The limit block 78 moving backward will release the obstruction to the scraper 76. Then, the second handle 711 is grasped to remove the scraper 76. Then, the new scraper 76 is aligned with the positioning plate 74 and moved downward. The scraper 76 moving downward will squeeze the inclined surface of the limit block 78. After the inclined surface of the limit block 78 is squeezed, it will move backward to squeeze the limit spring 77 to produce a reaction force. When the scraper 76 and the block 75 come into contact, the scraper 76 will be unable to move downward and at this time the scraper 76 will release the squeezing of the limit block 78. The limit block 78 will move forward under the push of the reaction force of the limit spring 77 to limit the scraper 76, and the installation work is completed.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
