Description

Technical Field

[0001] The invention belongs to the field of industrial containers, in particular to a basin with a stainless steel mesh and a processing technology thereof. Background Art

[0002] The discharge port of industrial equipment generally uses stainless steel bowls or basins as collection devices. The copper nails of semiconductor copper nail processing equipment are cut and stamped from copper wire. During the copper nail processing process, metal dust is generated. This metal dust will fall along with the copper nails. If traditional stainless steel bowls or basins are used to collect them, the metal dust and copper nails will mix together, increasing the difficulty of subsequent separation of the copper nails and metal dust. Therefore, a receiving device is required to initially separate the metal dust from the copper nails. If the traditional stainless steel bowls or basins are punched mechanically or laser to make them breathable, not only is the processing technology complicated and the economic cost high, but the opening rate is ≤25%, which cannot achieve the goal of an initial separation rate of ≥96% for the copper nails and dust. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings of the prior art, the present invention proposes a basin with a stainless steel mesh, with an opening rate of ≥55%, which can collect components and effectively divert dust. The technical problem to be solved by the present invention is achieved through the following technical solutions:

[0004] A basin with a stainless steel mesh comprises an upper edge, side walls and a bottom, wherein the upper edge, side walls and bottom are formed by a stainless steel mesh; the upper half of the side wall and the upper edge each have three layers, namely a first stainless steel layer, a stainless steel mesh layer and a second stainless steel layer; the stainless steel mesh layer is tightly fitted to the first stainless steel layer and the second stainless steel layer respectively; the outermost small arc of the first stainless steel layer is connected to the outermost small arc of the second stainless steel layer by spot welding.

[0005] Furthermore, the wire diameter of the stainless steel mesh is 0.1mm-0.2mm.

[0006] Furthermore, the mesh number of the stainless steel mesh is 30-60 mesh.

[0007] Specifically, the number of spot welds is 6-8.

[0008] In particular, basins are replaced by bowls.

[0009] A process for producing a basin with a stainless steel mesh comprises the following steps:

[0010] Step 1: Cut the stainless steel mesh into a circle with a diameter of 165 mm; set 6-8 triangular arc-shaped notches on the outer diameter of the circle;

[0011] Step 2: Cut the existing stainless steel basin from the middle and upper part of the side wall, leaving only the middle and upper part, and cut 2 in total;

[0012] Step 3: Place the existing first stainless steel basin, the first stainless steel basin with the middle and upper portion retained, the stainless steel mesh from step 1, the second stainless steel basin with the middle and upper portion retained, and the existing second stainless steel basin in order from top to bottom on the extrusion platform. Slowly press down with the extrusion head. During the pressing process, the stainless steel mesh should be symmetrically distributed. Any deviation should be corrected in time so that the stainless steel mesh forms a basin shape and fits tightly with the upper and lower components.

[0013] Step 4: spot weld the outermost small arcs of the first stainless steel basin and the second stainless steel basin, with 6-8 weld points evenly distributed;

[0014] Step 5: Finally, the topmost existing first stainless steel basin and the bottommost existing second stainless steel basin are removed to form a basin with a stainless steel mesh.

[0015] Furthermore, the maximum cross-sectional length of the stainless steel mesh in step 1 is 194 mm, the stretched length of the stainless steel mesh after extrusion is 194-165=29 mm, the wire diameter of the stainless steel mesh is 0.1 mm-0.2 mm, and the mesh number of the stainless steel mesh is 30 mesh-60 mesh.

[0016] Furthermore, the arc width of the triangular arc-shaped notch in step 1 is 18 mm, and the arc depth is ≤ 18 mm.

[0017] Furthermore, the shape of the extrusion head in step 3 is substantially consistent with the shape of the bottom of the basin.

[0018] The invention has an opening rate of ≥55%, low cost, and is particularly suitable for collecting devices and dust mixed together. It can collect devices and effectively divert dust at the same time, with a separation rate of ≥96%. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 It is a structural schematic diagram of the present invention; Figure 2 for Figure 1 A top view of Figure 3 for Figure 1 A magnified view of part A. Figures 1 to 3 As shown, a basin with a stainless steel mesh comprises an upper edge 1, a side wall 2 and a bottom 3, the upper edge 1, the side wall 2 and the bottom 3 are formed by a stainless steel mesh 4, the upper half of the side wall 2 and the upper edge 1 are three layers, namely a first stainless steel layer 5, a stainless steel mesh layer and a second stainless steel layer 6, the stainless steel mesh layer is tightly fitted to the first stainless steel layer 5 and the second stainless steel layer 6 respectively, the outermost small arc of the first stainless steel layer 5 and the outermost small arc of the second stainless steel layer 6 are connected by spot welding, an arc edge is set on the outermost side of the upper edge 1, that is, a first arc edge 7 is set on the outermost side of the first stainless steel layer 5, and a second arc edge 8 is set on the outermost side of the second stainless steel layer 6, and the first arc edge 7 and the second arc edge 8 are connected by spot welding.

[0025] The wire diameter of the stainless steel mesh 4 is 0.1mm-0.2mm, the mesh number of the stainless steel mesh 4 is 30 mesh-60 mesh, and the number of spot welds is 6-8; the wire diameter of the stainless steel mesh 4 in this embodiment is 0.14mm, which has sufficient strength and is easy to form. The mesh number of the stainless steel mesh 4 is 40 mesh, ensuring that the opening rate is ≥55%.

[0026] The invention can be made into a basin or a bowl.

[0027] A process for producing a basin with a stainless steel mesh comprises the following steps:

[0028] Step 1, cut the stainless steel mesh 4 into a circle with a diameter of 165mm, the maximum cross-sectional line length of the stainless steel mesh 4 is 194mm, the stretching length of the stainless steel mesh 4 during extrusion molding is 194-165=29mm, ensuring that the outer side of the stainless steel mesh 4 is controlled within a certain range, the wire diameter of the stainless steel mesh 4 is 0.1mm-0.2mm, the mesh number of the stainless steel mesh 4 is 30-60 mesh, the wire diameter of the stainless steel mesh 4 in this embodiment is 0.14mm, and the mesh number of the stainless steel mesh 4 is 40 mesh; 6-8 triangular arc notches 9 are set on the outer diameter of the circle, the arc width of the triangular arc notch 9 is 18mm, and the arc depth is ≤18mm to ensure that the stainless steel mesh 4 will not overlap or shear notches will appear during extrusion molding. There are 8 triangular arc notches 9 in this embodiment.

[0029] Step 2: Cut the existing stainless steel basin from the upper middle part of the side wall, leaving only the upper middle part, and cut 2 in total.

[0030] Step 3. Place the existing first stainless steel basin 10, the first retained middle and upper part of the stainless steel basin 11, the stainless steel mesh 4 of step 1, the second retained middle and upper part of the stainless steel basin 12, and the existing second stainless steel basin 13 on the extrusion platform from top to bottom, a total of 5 components, and slowly press down with the extrusion head 14. The shape of the extrusion head 14 is basically consistent with the shape of the bottom of the basin. During the pressing process, the stainless steel mesh should always be symmetrically distributed, and any deviation should be corrected in time so that the stainless steel mesh forms a basin shape and fits tightly with the upper and lower components.

[0031] Step 4: spot weld the outermost small arcs of the first retained middle and upper stainless steel basin 11 and the second retained middle and upper stainless steel basin 12. There are 6-8 welding spots, which are evenly distributed. The first retained middle and upper stainless steel basin 11 forms a first stainless steel layer 5, and the second retained middle and upper stainless steel basin 12 forms a second stainless steel layer 6.

[0032] In step 5, the topmost existing first stainless steel basin 10 and the bottommost existing second stainless steel basin 13 are finally removed to form a basin with a stainless steel mesh.

[0033] The present invention has the following advantages:

[0034] 1. A horizontal circular stainless steel mesh is directly squeezed and stretched into a basin shape.

[0035] 2. The stainless steel mesh itself is not strong enough, especially the upper part and the outer part that are grasped by hand. We used the existing stainless steel basin, cut it from the middle and upper part of the side wall, and only retained the middle and upper part and fixed it by spot welding to form a strong upper part and outer part.

[0036] 3. The formed stainless steel mesh has sufficient wire diameter strength (Φ=0.14mm), so it is strong enough to serve as the middle and bottom of the stainless steel basin.

[0037] 4. The formed stainless steel mesh is clamped in the middle and has become one piece, so it will not loosen or fall off.

[0038] 5. In order to prevent the stainless steel mesh from folding and shearing, a triangular arc notch is set.

[0039] 6. In order to prevent the stainless steel mesh from overlapping with the outermost arc edge of the basin, the diameter of the stainless steel mesh = the maximum cross-sectional length of the basin × 85% = 194mm × 85% = 165mm, and the stretched length of the stainless steel mesh after extrusion = 194-165 = 29mm.

[0040] 8. In order to ensure that the opening rate of the stainless steel mesh is ≥55%, it is necessary to select appropriate mesh number and wire diameter. The mesh number of this embodiment is 40# and the wire diameter is Φ=0.14mm.

[0041] Traditional stainless steel basins are generally made breathable by mechanical drilling or laser punching. Since the bottom and sides are curved rather than flat, the processing technology is very complicated and the economic cost is high. Moreover, the opening rate is ≤25% like that of ordinary perforated plates, which cannot achieve the purpose of a preliminary separation rate of copper nails and dust of ≥96%. If precision castings are used, the opening rate can reach ≥55%, but the membrane cost is extremely expensive and uneconomical. The present invention has a simple processing technology, does not require mechanical drilling or laser punching, and is low in cost.

[0042] In summary, the present invention has an opening rate of ≥55%, low cost, and is particularly suitable for collecting devices and dust mixed together. It can collect devices while effectively diverting dust, with a separation rate of ≥96%.
