[0016] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1As shown, a demagnetization-assisted transport device includes a support 1, guide rails 2, and a conveying platform 3. The support 1 includes legs 102 and a horizontal frame 101. The height of the legs 102 matches the height of the demagnetization window 401 of the demagnetizer 4 and is used to stably support the horizontal frame 101, allowing it to pass smoothly through the demagnetization window 401. The horizontal frame 101 is a long rectangular strip with two long sides and two short sides. The two long sides of the horizontal frame 101 are each a U-shaped groove 103 opening upward. A guide rail 2 is placed in each of the two U-shaped grooves 103. Each guide rail 2 consists of two metal rods and an insulating rod. The insulating rod is coaxially placed between the two metal rods, with their ends abutting each other. The metal rod is a steel rod 201. The insulating rod is a bakelite rod 202. The horizontal frame 101 passes horizontally through the demagnetization window 401 of the demagnetizer 4, and the portion located in the demagnetization window 401 is insulated. That is, the bakelite rod 202 is located in the demagnetization window 401, and the steel rod 201 is located on both sides of the demagnetization window 401. The length of the steel rod 201 is greater than the length of the tool to be demagnetized.

[0018] At least two sets of rollers 301 are installed beneath the conveyor table 3, which is supported by two guide rails 2. The tool to be demagnetized is placed on the conveyor table 3. When a worker pushes the conveyor table 3, the rollers 301 roll on the guide rails 2, driving the tool to move smoothly and efficiently back and forth from one side of the demagnetizer 4 to the other.

[0019] The U-shaped groove 103 can be divided into two sections, one on the left and one on the right. The U-shaped groove 103 is fixed horizontally to the sides of the demagnetizer 4. The two horizontal frames 101 are fixed horizontally to the left and right sides of the demagnetization window 401 via two legs 102 and a connection between the partition and the demagnetizer 4. Metal rods are placed in the U-shaped groove 103 on either side of the demagnetizer 4 window, and the bakelite rod 202 passes through the demagnetization window 401 and is located between the two metal rods.

[0020] The guide rail 2 is set to sandwich the bakelite rod 202 between two steel rods 201, and the bakelite rod 202 is located in the demagnetization window 401. The purpose is to enable the magnetic lines to have a clear cutting and disconnecting point when the tool is inserted into the demagnetizer 4 for demagnetization, so that the residual magnetism on the workpiece can be removed more thoroughly. The demagnetization process must meet two conditions, namely the overlapping of magnetic poles and the decreasing magnetic field strength. The demagnetizer 4 is controlled by alternating current, which can ensure the overlapping of magnetic poles. In order to meet the decreasing mode of magnetic field strength, the demagnetization auxiliary conveying device proposed in the utility model has its entire conveying table 3 passing through the demagnetizer 4 as a whole, so that the tool gradually leaves the magnetic field, and the magnetic field strength decreases until the residual magnetism on the tool approaches zero, thereby achieving the purpose of demagnetization.

[0021] In order to ensure safety and prevent the conveyor table 3 from sliding off the guide rail 2 after passing through the demagnetizer 4 as a whole, thereby causing a production accident, the utility model is provided with an anti-slip device at the bottom of the conveyor table 3. The anti-slip device includes two pairs of hooks 302 fixed to the bottom of the conveyor table 3, and two limiting beams 104 fixed on the horizontal frame 101 and parallel to the two short sides. The openings of the two pairs of hooks 302 point to their respective directions of movement and are symmetrically fixed to the bottom of the conveyor table 3. The two limiting beams 104 are symmetrically arranged near the left and right ends of the horizontal frame 101. The distance between the limiting beam 104 and the demagnetization window 401 is greater than the length of the conveyor table. When the conveyor table 3 drives the tool to pass through the demagnetizer 4, the hook 302 with the opening pointing to the direction of movement will be hooked on the limiting beam 104 at the corresponding position to ensure that the conveyor table can stop in time and prevent it from slipping.

[0022] During the entire demagnetization process, workers can place multiple pairs of cutting tools on the conveying table 3 at a time, and push the cutting tools back and forth to repeatedly pass through the demagnetizer 4 to achieve the demagnetization effect, which greatly improves the demagnetization efficiency.
