[0022] Figure 1 The schematic diagram of the structure of the bolt immersion and throwing device of the utility model is shown in FIG. Figure 1 The bolt immersion and throwing device has a cylindrical cage structure with an open top, which includes: a circular top support member 1 and a circular bottom plate 2 which are parallel to each other, a plurality of connecting rods 3 are vertically fixed between the lower surface of the circular top support member 1 and the upper surface of the circular bottom plate 2, the plurality of connecting rods 3 are arranged at equal intervals, and a plurality of circular connecting plates 4 are arranged parallel to each other and at equal intervals along the length direction of the connecting rods 3, and each circular connecting plate 4 intersects with all the connecting rods 3 vertically to form a plurality of first gaps A.

[0023] The inner surface of the annular bottom plate 2 is fixedly connected to the reinforcing rib group, and the reinforcing rib group intersects with the inner surface of the annular bottom plate 2 to form a plurality of second gaps B. A metal mesh 7 parallel to the annular bottom plate 2 is arranged in each second gap B, and the metal mesh 7 is respectively welded and fixed to the inner surface of the annular bottom plate 2 and the reinforcing rib group.

[0024] Furthermore, the reinforcing rib group includes at least one first reinforcing rib 5 and at least one second reinforcing rib 6 which intersect each other perpendicularly. In this embodiment, the number of the first reinforcing rib 5 is one, and the number of the second reinforcing rib 6 is two.

[0025] Furthermore, in order to facilitate the clamping of the bolt immersion and throwing device by a fixture such as an I-beam and reduce the weight of the bolt immersion and throwing device, a groove 11 is provided on the outer surface of the annular top support member 1.

[0026] Specifically, in order to enable the bolt-holding and immersion-swinging device to cooperate well with a clamp such as an I-beam and be clamped more firmly, the depth of the groove 11 is 50 to 80 mm and the width is 100 to 120 mm.

[0027] Furthermore, in order to prevent the metal mesh 7 from being deformed during the bolt immersion and throwing device, or even being damaged after being hit by the bolt workpiece, thereby causing the bolt workpiece to be thrown out, the strength of the metal mesh 7 is not less than 200Mpa. At the same time, from the perspective of cost control, the strength of the metal mesh 7 is not greater than 940Mpa, that is, the strength of the metal mesh 7 is 200~940Mpa.

[0028] Preferably, the strength of the metal mesh 7 is 600 MPa.

[0029] Furthermore, in order to be able to coat bolt workpieces of various specifications, the aperture of the metal mesh 7 is not greater than 20 mm.

[0030] Preferably, the pore size of the metal mesh is 10 mm.

[0031] Furthermore, in order to prevent the I-beam and other clamps from colliding or even damaging the connecting rod 3 and the annular connecting plate 4 when firmly clamping the bolt immersion device, the outer diameter of the annular bottom plate 2 is smaller than the outer diameter of the annular top support 1.

[0032] During operation, the bolt workpiece is placed in the bolt immersion and throwing device, and the bolt immersion and throwing device is firmly clamped by an I-beam or other clamps through the groove 11 on the outer surface of the circular top support 1, and then the bolt immersion and throwing device is immersed in the Dacromet liquid tank. Since the bolt immersion and throwing device is provided with a plurality of first gaps A and a metal mesh 7, the Dacromet liquid can flow freely into the bolt immersion and throwing device, and finally the I-beam or other clamps are driven by a motor to rotate forward and reverse, and then the bolt immersion and throwing device is swung, and the swing coating of the Dacromet liquid can be completed in a short time, so that the Dacromet liquid is evenly coated on the surface of the bolt workpiece to form a coating layer.

[0033] In summary, the utility model provides a bolt immersion and throwing device, which can coat bolt workpieces of various specifications by setting a first gap A and setting the aperture of the metal mesh 7 to 2-20 mm, and allows the Dacromet liquid to flow back to the Dacromet liquid tank smoothly to prevent it from remaining on the metal mesh 7, thereby realizing the recycling of the Dacromet liquid and saving the Dacromet liquid; by setting the strength of the metal mesh 7 to 200-940 MPa, the cost of the metal mesh 7 can be controlled, and the metal mesh 7 can be prevented from being deformed during immersion and throwing by the bolt immersion and throwing device, and from being damaged after being hit by the bolt workpiece, thereby causing the bolt workpiece to be thrown out; by making the outer diameter of the annular bottom plate 2 smaller than the outer diameter of the annular top support 1, it can prevent the I-beam and other clamps from colliding or even damaging the metal mesh 7 when firmly clamping the bolt immersion and throwing device.
