Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology for cold-drawn wires, specifically a sandblasting treatment device for the surface of cold-drawn wires. Background Technology

[0002] Cold drawing is a metal processing technique commonly used to improve the strength and surface quality of metal wires. During the cold drawing process, the metal wire is stretched through a die, reducing its cross-section and increasing its length, while its internal structure becomes more compact, thereby improving its mechanical properties. After cold drawing, the surface of the metal wire needs to be sandblasted to clean or improve its surface properties.

[0003] When existing metal wires are sandblasted, the diameter of the metal wires is small. During sandblasting, the abrasive is ejected from the nozzle in a fan shape. Only a portion of the abrasive contacts the metal wire. This portion of the abrasive carries impurities from the surface of the metal wire and is discharged at the same time. This portion of the abrasive needs to be filtered before it can be recycled. The other portion of the abrasive that does not contact the metal wire is discharged from the filter along with this portion, which increases the workload of the filter components and affects the filtration effect. It is also inconvenient to use the other portion of the abrasive that does not contact the metal wire directly. Utility Model Content

[0004] The purpose of this invention is to provide a cold-drawn wire surface sandblasting treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cold-drawn wire surface sandblasting treatment device includes a sandblasting device body, and a recycling mechanism is provided inside the sandblasting device body. The recycling mechanism includes:

[0007] The No. 1 collection component is fixedly installed inside the main body of the sandblasting device. The No. 1 collection component includes a fixed frame, and two U-shaped frames are fixedly installed at the lower end of the fixed frame. Slip rings are symmetrically slidably connected to the outside of the U-shaped frames, and a No. 1 collection frame is fixedly installed at one end of each of the two slip rings.

[0008] The second collection component is fixedly installed inside the main body of the sandblasting device. The second collection component includes a second collection frame that is fixedly installed on one side of the first collection frame.

[0009] The filter assembly is fixedly installed inside the main body of the sandblasting device.

[0010] Furthermore, a hopper is fixedly installed at the lower end of the main body of the sandblasting device, and a discharge pipe is fixedly installed at the lower end of the hopper.

[0011] Furthermore, a protective frame is fixedly installed at one end of the U-shaped frame, a bidirectional lead screw is rotatably connected inside the protective frame, and sliding sleeves are symmetrically screwed onto the outside of the bidirectional lead screw. One end of each of the sliding sleeves is fixedly connected to a No. 1 collection frame at a corresponding position, and a motor capable of driving the bidirectional lead screw to rotate is fixedly installed at one end of the protective frame.

[0012] Furthermore, a No. 1 collection hose is fixedly installed at one end of each of the two No. 1 collection frames on the same side, and a No. 1 tee discharge pipe is fixedly connected between the two No. 1 collection hoses.

[0013] Preferably, one end of the two No. 2 collection frames located on the same side is fixedly connected to a No. 2 collection hose, one end of the two No. 2 collection hoses is fixedly connected to a No. 2 three-way discharge pipe, a feeding pipe is fixedly installed inside the fixing frame, and nozzles are fixedly installed at both ends of the feeding pipe.

[0014] Preferably, the filtering component includes:

[0015] The filter chamber is fixedly installed inside the main body of the sandblasting device;

[0016] The filter screen is fixedly installed at an angle inside the filter chamber;

[0017] Multiple solenoid valves are fixedly embedded at one end of the lower surface of the filter chamber.

[0018] Preferably, an air outlet pipe is fixedly installed on the other end surface of the filter chamber, and both the No. 1 three-way discharge pipe and the No. 2 three-way discharge pipe are fixedly connected to the filter chamber.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The motor drives the bidirectional lead screw to rotate, adjusting the two No. 1 collection frames to the edge of the metal wire to accommodate metal wires of different diameters. The abrasive material in contact with the metal wire is collected by the No. 1 collection frame and enters the filter chamber through the No. 1 collection hose and the No. 1 three-way discharge pipe. By setting two No. 1 collection frames on the outside of the metal wire, the No. 1 collection frame divides the fan-shaped abrasive material into two parts. One part contacts the metal wire for surface treatment, reducing the amount of abrasive material used. The No. 2 collection frame collects the abrasive material that does not contact the metal wire, allowing this part of the abrasive material to be discharged into the filter chamber through the No. 2 collection hose and the No. 2 three-way discharge pipe. This part of the filter chamber is directly discharged into the hopper for feeding and sandblasting of the sandblasting structure of the main body of the sandblasting device.

[0021] 2. The spray material discharged from the No. 1 three-way discharge pipe falls onto the filter screen surface and falls along the filter screen. Impurities are discharged through the filter screen under the suction generated by the fan. The filtered spray material falls to the solenoid valve. The unused spray material discharged from the No. 2 three-way discharge pipe is directly discharged to the solenoid valve. The solenoid valve opens and discharges the spray material into the hopper. This allows the filter assembly to filter only the spray material that comes into contact with the metal wire, reducing the amount of spray material filtered, reducing the workload of the filter assembly, and improving the filtration effect and efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 In this embodiment of the present invention, a cold-drawn wire surface sandblasting treatment device includes a sandblasting device body 1, a hopper 101 fixedly installed at the lower end of the sandblasting device body 1, a discharge pipe 102 fixedly installed at the lower end of the hopper 101, a recycling mechanism provided inside the sandblasting device body 1, the recycling mechanism including a first collection component 2 fixedly installed inside the sandblasting device body 1, the first collection component 2 including a fixing frame 201, two U-shaped frames 202 fixedly installed at the lower end of the fixing frame 201, slip rings 209 symmetrically slidably connected to the outer side of the U-shaped frames 202, a first collection frame 206 fixedly installed at one end of each of the two slip rings 209, a second collection component 3 fixedly installed inside the sandblasting device body 1, the second collection component 3 including a second collection frame 301 fixedly installed on one side of the first collection frame 206, and a filter component 4 fixedly installed inside the sandblasting device body 1.

[0031] Specifically, an external fan is connected to the air outlet pipe 404, which generates suction at the first collection frame 206 and the second collection frame 301 to attract the spray material. The first collection component 2 collects the spray material that comes into contact with the metal wire, and the second collection component 3 collects the spray material that does not come into contact with the metal wire. By collecting the two separately, the amount of spray material filtered by the filter component 4 is reduced. Example 1

[0032] like Figure 2-5 As shown, in this embodiment, a protective frame 203 is fixedly installed at one end of the U-shaped frame 202. A bidirectional lead screw 204 is rotatably connected inside the protective frame 203. Sliding sleeves 205 are symmetrically screwed onto the outside of the bidirectional lead screw 204. One end of each sliding sleeve 205 is fixedly connected to a first collection frame 206 at a corresponding position. A motor capable of driving the bidirectional lead screw 204 to rotate is fixedly installed at one end of the protective frame 203. A first collection hose 207 is fixedly installed at one end of each of the two first collection frames 206 on the same side. A first three-way discharge pipe 208 is fixedly connected between the two first collection hoses 207.

[0033] In this embodiment, the motor drives the bidirectional lead screw 204 to rotate. Through the engagement of the sliding sleeve 205 with the bidirectional lead screw 204, and the sliding limit of the slip ring 209 and the U-shaped frame 202, the distance between the two No. 1 collection frames 206 is adjusted to accommodate metal wires of different diameters. The two No. 1 collection frames 206 are adjusted to the edge of the metal wire, and then the spray material in contact with the metal wire is collected by the No. 1 collection frame 206. It enters the filter chamber 401 through the No. 1 collection hose 207 and the No. 1 three-way discharge pipe 208. Thus, by setting two No. 1 collection frames 206 on the outside of the metal wire, the No. 1 collection frame 206 divides the spray material sprayed in a fan shape into two parts. One part contacts the metal wire for surface treatment, reducing the amount of spray material used.

[0034] like Figure 3-5As shown, in this embodiment, two No. 2 collection frames 301 located on the same side are fixedly connected to one end of a No. 2 collection hose 302, and one end of the two No. 2 collection hoses 302 is fixedly connected to a No. 2 three-way discharge pipe 303. A feed pipe 304 is fixedly installed inside the fixing frame 201, and nozzles 305 are fixedly installed at both ends of the feed pipe 304.

[0035] In specific implementation, the feeding pipe 304 is connected to the sandblasting mechanism of the main body 1 of the sandblasting device, so that the abrasive material can be sprayed out from the nozzle 305 for sandblasting treatment. The second collection frame 301 collects the abrasive material that does not come into contact with the metal wire, and discharges this part of the abrasive material into the filter chamber 401 through the second collection hose 302 and the second three-way discharge pipe 303, so that this part of the filter chamber 401 is directly discharged into the material hopper 101 for feeding and sandblasting of the sandblasting structure of the main body 1 of the sandblasting device.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the filter assembly 4 includes: a filter chamber 401 fixedly installed inside the main body 1 of the sandblasting device; a filter screen 403 fixedly installed obliquely inside the filter chamber 401; and multiple solenoid valves 402 fixedly embedded at one end of the lower surface of the filter chamber 401. An air outlet pipe 404 is fixedly installed on the other end surface of the filter chamber 401, and a first three-way discharge pipe 208 and a second three-way discharge pipe 303 are both fixedly connected to the filter chamber 401.

[0037] In practice, the spray material discharged from the No. 1 three-way discharge pipe 208 falls onto the surface of the filter screen 403 and falls along the filter screen 403. Impurities are discharged through the filter screen 403 under the suction generated by the fan. The filtered spray material falls to the solenoid valve 402. The unused spray material discharged from the No. 2 three-way discharge pipe 303 is directly discharged to the solenoid valve 402. The solenoid valve 402 opens and discharges the spray material into the hopper 101. This allows the filter assembly 4 to filter only the spray material that comes into contact with the metal wire, reducing the amount of spray material filtered, reducing the workload of the filter assembly 4, and improving the filtration effect and efficiency.
