Description

Technical Field

[0001] The utility model relates to the technical field of rust removal devices, in particular to a sandblasting rust removal device used for high-speed welding wire production. Background Art

[0002] The raw materials of welding wire are rusted and oily due to storage and transportation. Before welding wire production, the surface of raw metal wire is attached with oxide layer, rust, oil, etc. The oxide layer will cause the loss of rusted raw materials and the rusted wire cannot be directly produced and used. The surface of raw metal wire needs to be cleaned before production. After the metal wire is mechanically removed by the shelling machine before drawing, it is removed by the rust removal device to remove the oxide, oil and other pollutants on the surface of the wire.

[0003] Due to environmental protection requirements, most of the same industry is currently developing the use of abrasive belt machines to remove wire oxide scale instead of pickling to remove oxides. This process uses two or more sets of abrasive belts to rotate at high speed on the surface of the wire to achieve the purpose of surface cleaning. Since the abrasive belt is a fragile and consumable part, during use, the high-speed rotation will reduce the service life of the abrasive belt. In rainy weather and air humidity, the abrasive belt and raw wire are damp, and the use of the abrasive belt increases. The cost of the abrasive belt is high, and the abrasive belt needs to be replaced frequently, which increases the cost and reduces the work efficiency. Replacing the abrasive belt requires adjusting the relaxation tension of the abrasive belt. If the adjustment is not good, the purpose of rust removal cannot be achieved, which affects the subsequent production requirements. It is also easy to wear the parts of the equipment itself, increasing maintenance costs and replacement costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to solve the problem that the existing rust removal equipment mainly removes rusty materials on the surface of raw materials by sanding belts, and since the sanding belts are easily damaged and consumable, the sanding belts need to be replaced, which increases production costs and reduces work efficiency, a sandblasting rust removal device for high-speed welding wire production is now provided.

[0005] The utility model solves the technical problem by adopting the following technical solution: a sandblasting and rust removal device for high-speed welding wire production, comprising a frame, and also comprising a first sandblasting mechanism and a second sandblasting mechanism arranged on the frame, wherein the first sandblasting mechanism and the second sandblasting mechanism are arranged in sequence along the welding wire conveying direction, the first sandblasting mechanism is used to remove the oxide layer, rust or oil stain on the surface of the welding wire, and the second sandblasting mechanism is used to polish the surface of the welding wire;

[0006] The first sandblasting mechanism and the second sandblasting mechanism both include a silo, a box, a tray and an air source. The silo on the first sandblasting mechanism is used to store coarse-grained sandblasting or abrasives, and the silo on the second sandblasting mechanism is used to store fine-grained sandblasting or abrasives. The box is fixedly mounted on the frame, and the tray is arranged on the box. A nozzle is arranged on the tray, and the nozzle is arranged toward the welding wire. The air source and the silo are both connected to the nozzle. Compared with the prior art, the present solution first sets a first sandblasting mechanism in the direction of welding wire conveying. The first sandblasting mechanism removes the oxide layer, rust or oil stains on the surface of the welding wire, and there is no need to stop the machine to change the sand belt, thereby improving work efficiency and reducing production costs. At the same time, a greater breakthrough is made in protecting the environment. Furthermore, the subsequent second sandblasting mechanism is used to polish the surface of the welding wire to improve the processing efficiency of the subsequent welding wire.

[0007] In order to ensure the rust removal and polishing of the outer surface of the welding wire, in some preferred embodiments, a plurality of nozzles are installed on the material tray, and the plurality of nozzles are arranged around the welding wire. A plurality of nozzles are installed on the material tray and arranged around the circumference of the welding wire to cover the outer surface of the welding wire, so as to ensure the rust removal or polishing of the welding wire is stable and reliable.

[0008] In order to prevent the sandblasting or abrasives ejected from the nozzles from colliding with each other, which causes the sandblasting or abrasives to consume internal energy and fail to achieve the effect of rust removal or polishing the welding wire, in some preferred embodiments, several nozzles are arranged at intervals along the axial direction of the welding wire. By arranging several nozzles at intervals along the axial direction of the welding wire and staggering the nozzles along the axial direction of the welding wire, the sandblasting between the nozzles will not collide with each other and consume internal energy.

[0009] In order to ensure uniform rust removal and polishing of the outer periphery of the welding wire, in some preferred embodiments, the plurality of nozzles are evenly distributed along the circumference. The plurality of nozzles are evenly distributed along the circumference to ensure uniform rust removal and polishing of the outer periphery of the welding wire.

[0010] In order to better remove rust and polish the welding wire, in some preferred embodiments, the box body is a gear box, the frame is provided with a driving mechanism connected to the gear box, and the output end of the gear box is connected to the material tray. The gear box is driven by the driving mechanism, and the material sheet is rotated, so that the nozzle rotates with the welding wire as the center, and the welding wire is rusted and polished in all directions.

[0011] In order to facilitate sandblasting and the entry of abrasive into the nozzle, in some preferred embodiments, the material bin is located above the material tray.

[0012] In order to facilitate the recovery of sandblasting and abrasives, in some preferred embodiments, the first sandblasting mechanism and the second sandblasting mechanism are both provided with a recovery mechanism for recovering sandblasting or abrasives. By correspondingly providing the recovery mechanism below the first sandblasting mechanism and the second sandblasting mechanism, the cost of rust removal is greatly reduced.

[0013] In order to realize the sandblasting mechanism, in some preferred embodiments, the recovery mechanism includes a recovery trough, and the recovery trough is arranged below the upper nozzles of the corresponding first sandblasting mechanism and the second sandblasting mechanism.

[0014] In some preferred embodiments, a recovery port is provided on the recovery tank, a screw conveying mechanism is provided in the recovery tank, and an output end of the screw conveying mechanism is provided in the recovery port.

[0015] The beneficial effects of the utility model are as follows: when the sandblasting and rust removal device for high-speed welding wire production is used, a first sandblasting mechanism is first arranged in the direction of welding wire conveying. The first sandblasting mechanism removes the oxide layer, rust or oil stains on the surface of the welding wire, and there is no need to stop the machine to change the sand belt, thereby improving work efficiency and reducing production costs. At the same time, a greater breakthrough is made in protecting the environment. Furthermore, the subsequent second sandblasting mechanism is used to polish the surface of the welding wire, thereby improving the processing efficiency of subsequent welding wires, and avoiding the problem that the existing rust removal equipment mainly removes rusty substances on the surface of raw materials through sand belts. Since the sand belts are easily damaged and consumable, the sand belts need to be replaced, which increases production costs and reduces work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The first sandblasting mechanism 2 and the second sandblasting mechanism 3 both include a silo 4, a box 5, a tray 6 and an air source 7. In this embodiment, the air source 7 is a compressor. The silo 4 on the first sandblasting mechanism 2 is used to store coarse-grained sandblasting or abrasives, wherein the abrasives are environmentally friendly abrasives, such as ceramic sand, stainless steel sand, etc., to reduce dust pollution. The silo 4 on the second sandblasting mechanism 3 is used to store fine-grained sandblasting or abrasives. The box 5 is fixedly mounted on the frame 1, and the tray 6 is arranged on the box 5.
