Description

Technical Field

[0001] The present application relates to the technical field of equipment for cleaning oxide scale of round steel forgings, and in particular to a device for treating oxide scale on the surface of round steel. Background Art

[0002] Round steel forgings refer to shaft parts made by forging technology. They are usually used to bear and transmit power or torque. They are widely used in various mechanical equipment, such as automobiles, machine tools, and reducers. During the forging or heat treatment process, metals at high temperatures are more likely to react with oxygen, thereby forming oxide scale on the metal surface. This layer of oxide scale may have an adverse effect on the performance of the metal, such as reducing the corrosion resistance and fatigue strength of the metal. Therefore, in the subsequent processing process, this layer of oxide scale usually needs to be removed.

[0003] The prior art discloses a device for removing oxide scale from shaft forgings, which includes a frame fixed vertically on the ground, with hydraulic cylinders provided at both ends of the frame in the height direction, center tops provided on the piston rods of the two hydraulic cylinders, and center holes matched with the center tops reserved at both ends of the forgings; a bearing plate is slidably connected to the side wall of the frame, a base is provided on the side wall of the bearing plate, a shaft sleeve for the forging to pass through is rotatably connected to the base, a number of circumferentially arranged steel brushes are connected to the inner wall of the shaft sleeve, a first driving member for driving the shaft sleeve to rotate is provided on the bearing plate, and a second driving member for driving the bearing plate to move along the height direction of the frame is provided on the frame.

[0004] With regard to the above-mentioned related technologies, shaft forgings are generally in an axially horizontal clamping state during forging. When the oxide scale removal device is in use, the staff is required to adjust the shaft forgings to a vertical posture first, and then accurately place them into the center hole. Since the temperature of the shaft forgings is relatively high at this time, it will take a lot of time to adjust the posture through the forging clamping device, which will seriously affect the oxide scale removal efficiency of the shaft forgings. Utility Model Content

[0005] In order to reduce the impact of posture adjustment of round steel forgings on the oxide scale removal efficiency, the present application provides a device for treating oxide scale on the surface of round steel.

[0006] The present application provides a device for treating round steel surface oxide scale using the following technical solution:

[0007] A device for treating oxide scale on the surface of round steel, comprising:

[0008] A mounting frame, wherein two support frames are connected to the mounting frame, and a mounting cavity is left between the two support frames;

[0009] Two fixed rollers, which are located in the installation cavity. The two fixed rollers are axially aligned and horizontally arranged, and both ends of the fixed rollers are rotatably connected to the two support frames respectively;

[0010] A lifting cross bar, which is connected to the mounting frame, and a plurality of wire brushes are connected to the lifting cross bar, and the wire brushes are located directly above the middle gap between the two fixed rollers.

[0011] By adopting the above technical solution, when the surface scale of the round steel needs to be removed, the round steel is clamped by the forging clamping device and inserted between the wire brush and the two fixed rollers. At this time, the wire brush contacts the surface of the round steel, and then the fixed rollers are driven to rotate. When the fixed rollers rotate, the round steel is driven to rotate. When the round steel rotates, it contacts the wire brush, so that the scale on the surface of the round steel is brushed off; The designed device for treating the surface scale of round steel can provide an installation foundation for the support frame through the mounting frame, support the fixed rollers through the support frame, form a support structure for driving the round steel to rotate through the fixed rollers, and there is no need to adjust the posture of the round steel during placement, and the requirement accuracy of the placement position is also relatively low, reducing the influence of the posture adjustment of round steel forgings on the scale removal efficiency. A plurality of wire brushes can be installed through the lifting cross bar, and the wire brushes can cooperate with the fixed rollers to clean the scale on the surface of the round rod. At the same time, the rolling of the round steel on the fixed rollers can also cause the scale to peel off through vibration.

[0012] In a specific feasible implementation scheme, sliding blocks are rotatably connected to both ends of the fixed rollers, and at least one of the sliding blocks installed on the fixed roller is slidably connected to the support frame to change the axial distance between the two fixed rollers, and a fixing unit is arranged on the support frame, and the fixing unit is connected to the sliding block for fixing the sliding block.

[0013] By adopting the above technical solution, the designed sliding blocks can adjust the axial distance between the two fixed rollers through sliding, so as to adapt to round steel with different diameters, and the position of the sliding blocks can be fixed through the fixing unit.

[0014] In a specific feasible implementation scheme, the fixing unit includes a fixing bolt. A strip-shaped groove is formed on the support frame, and the screw rod section of the fixing bolt passes through the strip-shaped groove and is threadedly connected to the sliding block.

[0015] By adopting the above technical solution, the designed fixing unit can fix the position of the sliding block through the fixing bolt.

The guide rods are slidably connected to the mounting frame, and a lifting unit is connected to the mounting frame. The lifting unit is connected to the lifting cross bar for lifting the lifting cross bar.

[0017] By adopting the above technical solution, the designed guide rod and lifting unit can realize the height adjustment of the lifting cross bar, and further adapt to round steel with different diameters.

[0018] In a specific feasible embodiment, the lifting unit includes a lifting cylinder, the lifting cylinder is connected to the mounting bracket, and the lifting cylinder is connected to the lifting cross bar, and the axial direction of the piston rod of the lifting cylinder is consistent with the sliding direction of the guide rod.

[0020] In a specific feasible embodiment, a plurality of sliding rods are slidably connected to the lifting cross bar, the sliding rods slide in the vertical direction, and the wire brush is connected to the mounting end of the sliding rod below the lifting cross bar.

[0021] By adopting the above technical solution, the wire brush designed to be mounted on the sliding rod can clean the scale on the surface of cylindrical forgings with variable diameters.

[0022] In a specific feasible embodiment, a wire winding pulley is rotatably connected to one of the guide rods, a flattening cable is wound around the wire winding pulley, and the flattening cable passes through a plurality of the sliding rods and is connected to the other guide rod.

[0023] By adopting the above technical solution, the designed flattening cable can lift the wire brush before the round steel is placed on the two fixed rollers, avoiding the wire brush from affecting the placement of the round steel.

[0024] In a specific feasible embodiment, a plurality of recessed annular grooves are formed on at least one of the fixed rollers, and the recessed annular grooves are coaxially arranged with the fixed rollers.

[0025] By adopting the above technical solution, the fixed roller designed with recessed annular grooves can improve the peeling efficiency of the scale on the surface of the round steel during the rolling process, and can reduce the possibility of the scale adhering to the fixed roller.

Detailed Description of the Embodiment

[0035] The following will Figures 1-4 further describe the present application in detail with reference to the attached

[0036] The embodiment of the present application discloses a device for treating the scale on the surface of round steel.

[0037] Refer to Figure 1, A device for treating the scale on the surface of round steel includes a mounting frame 1, a support frame 2, and a fixed roller 3. The number of support frames 2 is two, and the support frames 2 are welded and fixed to the mounting frame 1. There is an installation cavity between the two support frames 2. The number of fixed rollers 3 is two, and the fixed rollers 3 are located in the installation cavity. The axial directions of the two fixed rollers 3 are the same and are horizontally arranged. Both ends of the fixed roller 3 are rotatably connected to the two support frames 2 respectively; in this application, the fixed roller 3 can be manually driven or driven by a motor. Both fixed rollers 3 can be externally connected with a driving structure, or only one fixed roller 3 can be externally connected with a driving structure. In this embodiment, the fixed roller 3 is driven by a motor, and only one fixed roller 3 is externally connected with a motor.

[0038] Referring to Figure 1 , in order to adapt to round steel forgings with different diameters, sliding blocks 31 are rotatably connected to both ends of the fixed roller 3, and at least one sliding block 31 installed on the fixed roller 3 is slidably connected to the support frame 2. The sliding direction of the sliding block 31 is horizontally set to realize the adjustment of the axial distance between the two fixed rollers 3. In this application, one fixed roller 3 can slide relative to the support frame 2, or both fixed rollers 3 can slide relative to the support frame 2. As long as the axial distance between the two fixed rollers 3 can be changed. In this embodiment, preferably, one of the fixed rollers 3 can slide relative to the support frame 2.

[0039] Referring to Figure 2 , in order to improve the peeling efficiency of the scale on the surface of the round steel during the rolling process and reduce the possibility of the scale adhering to the fixed roller 3, multiple recessed annular grooves 32 are provided on at least one fixed roller 3. The recessed annular grooves 32 are coaxially arranged with the fixed roller 3, and the multiple recessed annular grooves 32 are distributed along the axial direction of the fixed roller 3.

[0040] Referring to Figure 2 , after the axial distance between the two fixed rollers 3 is adjusted according to the diameter of the round steel forging, it is necessary to fix the sliding block 31 to prevent the sliding block 31 from sliding again during the scale cleaning process, resulting in the dropping of the round steel forging. Therefore, a fixing unit 6 is provided on the support frame 2. The fixing unit 6 is connected to the sliding block 31 and is used to fix the sliding block 31.

[0041] Referring to Figure 2 , the fixing unit 6 includes a fixing bolt 61. A strip-shaped groove 21 is provided on the support frame 2. The screw section of the fixing bolt 61 passes through the strip-shaped groove 21 and is threadedly connected to the sliding block 31. By turning the fixing bolt 61, the relative static state of the sliding block 31 and the support frame 2 can be realized.

[0042] Referring to Figure 3, The round steel forgings roll on the rolling support structure formed by two fixed rollers 3, and a part of the surface scale can be peeled off through vibration. In order to further improve the processing efficiency of the scale, the round steel surface scale processing device further includes a lifting cross bar 4 and a plurality of wire brushes 5. The lifting cross bar 4 is connected to the mounting frame 1, the wire brushes 5 are connected to the lifting cross bar 4, and the plurality of wire brushes 5 are distributed along the axial direction of the fixed roller 3 on the lifting cross bar 4. The wire brushes 5 are located directly above the middle gap between the two fixed rollers 3.

[0043] Refer to Figure 3 , In order to adapt to round steel forgings with different diameters, guide rods 41 are welded and fixed at both ends of the lifting cross bar 4. The guide rods 41 are slidably connected to the mounting frame 1, and a lifting unit 7 is connected to the mounting frame 1. The lifting unit 7 is connected to the lifting cross bar 4 and is used to drive the lifting cross bar 4 to lift and lower in the vertical direction.

[0044] Refer to Figure 3 , The lifting unit 7 includes a lifting cylinder 71. The lifting cylinder 71 is bolted to the mounting frame 1, and the piston rod of the lifting cylinder 71 is bolted to the lifting cross bar 4. The axial direction of the piston rod of the lifting cylinder 71 is the same as the sliding direction of the guide rod 41, and both are vertically arranged.

[0045] Refer to Figure 3 and Figure 4 , In order to be able to clean the surface scale of variable-diameter round steel forgings, a plurality of sliding rods 8 are slidably connected to the lifting cross bar 4. The sliding rods 8 are T-shaped and slide in the vertical direction. The wire brushes 5 are bolted to the mounting ends of the sliding rods 8 below the lifting cross bar 4. During cleaning, the wire brushes 5 are in contact with the surface of the round steel forgings under the action of the sliding rods 8 and their own gravity. Since the round steel forgings have variable diameters, the downward sliding lengths of the sliding rods 8 in different regions along the axial direction of the fixed roller 3 are different.

[0046] Refer to Figure 3 and Figure 4 , In order to avoid interference caused by the placement of the wire brushes 5 on the round steel forgings, a winding reel 9 is rotatably connected to one of the guide rods 41. A leveling cable 91 is wound and connected to the winding reel 9. The leveling cable 91 passes through a plurality of sliding rods 8 at the same time and is bolted to the other guide rod 41. By rotating the winding reel 9, the leveling cable 91 can be driven to be straightened, so that the plurality of sliding rods 8 drive the wire brushes 5 to move towards the side away from the fixed roller 3.

[0047] The implementation principle of an oxide scale treatment device for the surface of round steel in an embodiment of this application is as follows: Apply force to the sliding block 31. While the sliding block 31 slides, it drives one of the fixed rollers 3 to approach or move away from the other fixed roller 3 until the axial distance between the two fixed rollers 3 is appropriate. Then, the position of the sliding block 31 is fixed by the fixing bolt 61. At the same time, the leveling cable 91 is straightened by the winding reel 9. The leveling cable 91 pulls up the wire brush 5 through the sliding rod 8 to prevent the wire brush 5 from affecting the placement of the round steel. Then, the round steel is clamped by the forging clamping device and inserted between the wire brush 5 and the two fixed rollers 3. At this time, the wire brush 5 contacts the surface of the round steel. Then, drive the fixed roller 3 to rotate. While the fixed roller 3 rotates, it drives the round steel to rotate. While the round steel rotates, it contacts the wire brush 5, causing the oxide scale on the surface of the round steel to be brushed off.

[0048] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
