Detailed Description
The present invention will be described with reference to specific embodiments.
Fig. 4 is the internal structure schematic diagram of dust collector, fig. 5 is the utility model discloses dust collector's end view, as shown in fig. 4 and fig. 5, dust collector sets up in work box 24, install heating element 5 in the work box 24, heating element 5 is connected with heating gun 51, heating gun 51 is inside to be fixed with core wire 52.
The dust removing device comprises: dust removal mechanism 3, complementary unit 4. The dust removing mechanism 3 includes: a suction pump 31 fixed inside the work box 24, a housing chamber 32 communicating with the suction pump 31 through a pipe, and a suction pipe 33 communicating with the housing chamber 32. The assist mechanism 4 includes: the air outlet pump 41 is fixed in the work box 24, and the heat insulation cover 42 is fixed on the end face of the work box 24, and an air outlet pipe 411 is communicated with an air outlet of the air outlet pump 41.
The air suction pipe 33, the air outlet pipe 411 and the heating gun 51 are all positioned in the heat shield 42. The end face of the core wire 52 is located outside the heat shield 42, the end faces of the air suction pipe 33 and the air outlet pipe 411 are located inside the heat shield 42, and the air outlet of the air outlet pipe 411 is located on the right side of the air inlet of the air suction pipe 33.
When the core wire 52 is melted and welded, a large amount of heat is emitted around the core wire 52, which causes the temperature around the core wire 52 to rise, and compared with the position away from the core wire 52, a negative pressure is formed, air away from the core wire 52 moves towards the core wire 52, and air at the core wire 52 moves towards a high position, so that a small air flow circulation is formed. In prior processes, the gas flow circulation would cool the surrounding core wire 52 very quickly, and the welding time itself would be short, making this negative pressure gas flow circulation unusable. The device utilizes the circulation of negative pressure airflow caused by the temperature difference between the pre-welding and the welding to enlarge the influence, and sets a dust removal mechanism 3 and an auxiliary mechanism 4 to realize negative pressure dust removal around the welding seam. The specific principle is as follows:
the heat gun 51, the air outlet pipe 411 and the air suction pipe 33 are surrounded by the heat insulating cover 42, so that a heat exchange chamber 421 is formed inside the heat insulating cover 42. The heat is retained by the structure, and the circulating space of the airflow circulation is reduced so as to enlarge the negative pressure influence. And the influence of two pumps for air suction and air outlet is assisted, so that the air flow circulation rate is increased. The air outlet pump 41 is used for exhausting air through the air outlet pipe 411, blowing up the adhesion debris at the welding seam and the debris on the table top, and sucking the debris into the accommodating chamber 32 from the air suction pipe 31 for temporary storage after the air suction pump 31 is used for air inlet. Set up the cooperation negative pressure like this, can be along with the processing of welding seam constantly around clearance mesa and the welding seam, avoided the piece to influence the welding seam quality effectively.
The length of the air outlet pipe 411 in the heat shield 42 is longer than that of the air suction pipe 33 in the heat shield 42, so that the air outlet pipe is beneficial to contacting the periphery of a welding seam firstly and then sucking air to suck debris, the air circulation is beneficial, and the requirement on the output power of the air suction pump 31 can be reduced. The weld points of the core wire 52 are located outside the heat shield 42 to avoid the end face of the heat shield 42 from touching the table and work area and affecting the weld.
The bottom of the accommodating chamber 32 is hinged with a turning plate 321, a hinge column 322 is arranged between the turning plate 321 and the side wall of the accommodating chamber 32, and the hinge column 322 is positioned at one side close to the getter pump 31. The bottom of the working box 24 is provided with a discharge port 241, the discharge port 241 is positioned under the turning plate 321, and the length of the turning plate 321 is smaller than that of the discharge port 241. The turning plate 321 with the length smaller than that of the discharge port 241 is arranged, so that the turning plate 321 cannot collide with the side wall of the discharge port 241 when turning. The waste chips coming from the suction pipe 33 are stored in the containing chamber 32, and when the waste chips need to be discharged, the turning plate 24 is turned over, so that the containing chamber 32 is communicated with the discharge port 241, and the waste chips are located at a position close to the turning plate 24 due to the suction effect, so that the waste chips in the containing chamber 32 can be basically discharged.
The air suction pipe 33 includes: a first section 331 communicating with the accommodating chamber 32, a second section 332 communicating with the first section 331, and a third section 333 communicating with the second section 332, wherein the third section 333 is positioned inside the heat shield 42. The third section 333 has a diameter smaller than that of the second section 332, and the second section 332 has a diameter smaller than that of the first section 331. The smaller diameter of the debris entering from the third section 333 provides more negative pressure and increases the rate of passage of the debris to avoid the debris not being sucked in after the weld is completed, and the subsequent gradual increase in diameter is based on the debris having entered the work box 24 to avoid the debris becoming clogged due to the lengthy length of the suction tube 33, thus providing a larger diameter at the rear end. The diameter of the second section 332 is located between the first section 331 and the third section 333 and serves as a diameter transition to mitigate the impact of debris with the suction duct 33.
Fig. 5 is an end view of the dust removing apparatus of the present invention, and as shown in fig. 5, the diameter of the air outlet pipe 411 is larger than that of the third section 333. This arrangement causes the exit gas to have a lower velocity than the inlet gas to promote movement of the gas stream towards the third section 333 and allows the exit gas to take care of a larger surface for guiding debris.
The assist mechanism 4 further includes: and the clamping jaw 43 is positioned on the outer side of the heat shield 42, one end of the clamping jaw 43 is connected with the outer wall of the heat shield 42, and the other end is provided with a rotating ball 431. The rotating ball 431 is rotatably connected in the work box 24. The position of the heat shield 42 is further stabilized by the claws 43. The rotating ball can rotate freely, but a third groove 244 is formed in the working box 24, the rotating ball 431 is located in the third groove 244, the moving of the claw 43 can collide with the side wall of the third groove 244, and the limitation on the claw 43 is achieved. When the heat shield 42 is to be removed for servicing the equipment, the heat shield 42 is removed by pulling the latch 43 and the rotating ball 431 is slightly rotated in the third recess 244.
