Description

TECHNICAL FIELD

[0002] Hot strength alloy steel forging round is widely used in the fields of aerospace, energy and chemical industry, etc. due to its excellent high-temperature strength, oxidation resistance and creep resistance. However, its high hardness and wear resistance make surface treatment, especially polishing, necessary. Polishing can make the surface of the forging round smoother, reduce roughness, and thus improve its smoothness and aesthetics, which is particularly important for parts that need high-precision machining, because a smooth surface can reduce friction and wear, prolonging the service life.

[0003] During the polishing action, the forging round must be constrained by a restraint to prevent it from moving freely. Generally, the restraint is from one side of the forging round, which makes it impossible to polish the part that is in contact with the restraint during polishing, making the polishing process more complicated and increasing the labor intensity. Moreover, the forging round is generally heavy, and moving it to the polishing device requires a lot of labor, making the loading of the forging round more complex. Therefore, a polishing device for hot strength alloy steel forging round is proposed. SUMMARY

[0034] The polishing unit comprises a debris accommodating shell 113, cover sheets 114, leakage-proof covers 115, polishing rods 116, and helical beryllium copper wires 117. The lower part of the debris accommodating shell 113 is connected to the corresponding wire interface displacement table 112. Two mirror-image cover sheets 114 are arranged on the upper part of the debris accommodating shell 113. The upper part of the debris accommodating shell 113 is open. Two mirror-image leakage-proof covers 115 are arranged. The leakage-proof covers 115 are hingedly connected to the debris accommodating shell 113. Two helical beryllium copper wires 117 are arranged and connected to the corresponding leakage-proof covers 115.

The debris accommodating shell 113 is provided with openable and closable shell doors on both sides, so that the debris can be taken out.

[0035] The two ends of the assembly sheet 12 are provided with wings 13. The traction unit 14 is arranged at the central position of the two wings 13. The central position of the traction unit 14 is provided with a rod body I 136. The wall surface of the rod body I 136 is provided with wire teeth. Two supporting units 15 are arranged. The lower part of each supporting unit 15 is provided with a linkage sheet 123. The rod body I 136 passes through the linkage sheet 123 of the lower part of each supporting unit 15 in sequence. The upper part of the supporting unit 15 is provided with a recess 18. The two recesses 18 respectively support the lower part of the forged round to be polished on both sides. One side of each supporting unit 15 is provided with an expansion seat 126. The end of the expansion seat 126 farther from the recess 18 is provided with a constraint module 16. The lower part of the linkage sheet 123 is provided with a curved sheet 146. The curved sheet 146 is fan-shaped. The outer edge region of each curved sheet 146 is attached to the outer wall of the assembly sheet 12. The constraint unit for forged round polishing is used to constrain the forged round during polishing. During assembly, the upper two supporting units 15 are operated to swing by the lower traction unit 14. When the rotating position of each supporting unit 15 is close to the position of the lower workbench wall surface of the expansion resistance sheet 120, the forged round loaded on the workbench can roll into the supporting unit 15 along the head of the expansion resistance sheet 120. Then, the supporting unit 15 can return to the original position by the traction unit 14. At this time, the forged round can be supported. After the forged round stops moving, the two ends of the forged round can be respectively constrained by the constraint module 16, so that the forged round is constrained to be stationary. Then, the forged round in the transverse shape after being constrained can be rotated by the motor X, the sprocket arranged on the motor X, the chain matched with the sprocket, and the sprocket X 144 on the constraint module 16. The polishing of the forged round after the rotation is achieved. During the polishing, the supporting position of the supporting unit 15 to the forged round can be changed by the cooperation of the constraint module 16 and the traction unit 14.

[0036] The traction unit 14 includes a motor one 130 and a motor two 135. The rotating shaft of the motor one 130 is connected to a linkage rod 131. One end of the linkage rod 131 is provided with a connecting piece one 132. The other end of the connecting piece one 132 is connected to a guide rod 133. The rotating shaft of the motor two 135 is connected to the linkage rod 131. Two guide rods 133 are provided. The two guide rods 133 are mirror images and are provided on both sides of a rod body one 136. One end of the guide rod 133 is connected to a connecting piece two 134. The linkage rod 131, the connecting piece one 132, the connecting piece two 134, and the guide rod 133 are integrally connected. Both ends of the rod body one 136 are provided with a rotary support one 137. The rod body one 136 passes through the central positions of the connecting piece one 132 and the connecting piece two 134 through the rotary supports one 137 at both ends. The motor one 130 and the motor two 135 are fixedly connected to the outer walls of the two wings 13 by fasteners. The displacement of each supporting unit 15 is driven by the traction unit 14. Thus, the position of the supporting unit on the lower part of the forged circle is changed. The goal of polishing each position of the forged circle is achieved. The area of the polished forged circle is larger. The condition that the lower part cannot be polished due to the adhesion of the supporting unit is prevented.

[0037] The rod body one 136 is rotated by the motor two 135. The rod body one 136 cooperates with each supporting unit 15 to drive the displacement of all supporting units 15. The goal of changing the position of the supporting unit 15 on the lower part of the forged circle is achieved. The rotation direction of the threads inside the two lead pipes one 124 is controlled. The rod body one 136 is rotated. The displacement of the supporting unit 15 in the direction away from or towards the central position is controlled. That is, the two supporting units 15 are moved together towards the central position or are separated in the direction away from the central position. The connecting piece one 132, the connecting piece two 134, and the two guide rods 133 are rotated by the motor one 130 through the linkage rod 131. The supporting ball body 19 and the supporting table 17 are rotated to both sides. The outer edge of the supporting ball body 19 and the supporting table 17 is close to the wall of the workbench. The opening of the upper recess 18 of the supporting unit 15 is faced to the front and back. This is beneficial for loading and taking away the forged circle. The movement of the rod body one 136 is not hindered. The guiding ability of the guide rod 133 during the displacement of the supporting unit 15 is provided.

[0038] The supporting unit 15 comprises a supporting table 17 and a linkage sheet 123 fixedly connected to the lower part of the supporting table 17, a recessed opening 18 reserved in the upper part of the supporting table 17, a rotatable supporting ball 19 inlaid in the recessed opening 18, an expansion blocking sheet 120 connected to one end of the supporting table 17, a guide tube 125 and a threaded tube 124 reserved in the wall of the linkage sheet 123, two guide tubes 125 symmetrically arranged on both sides of the threaded tube 124, a guide rod 133 penetrating from the inside of the guide tube 125, a rod 136 penetrating from the inside of the threaded tube 124, the threads in the threaded tube 124 of the two supporting units 15 rotating in different directions, an inclined table 121 arranged at one end of the expansion blocking sheet 120, a buckling opening 127 reserved in the wall of the expansion blocking sheet 120, a movable sheet 128 arranged in the buckling opening 127, a constraint blocking table 122 arranged in the upper part of the movable sheet 128, an elastic telescopic rod 129 connected to the lower part of the movable sheet 128, and the lower part of the movable sheet 128 inserted into the buckling opening 127.

[0039] After the constraint unit rotates through the traction unit 14 during loading and unloading of the forged round, the supporting unit 15 is rotated by an angle to the left and right, so that the upper part of the supporting unit 15 is opened and arranged to the wall of the workbench, so that the forged round can be rolled into the supporting unit 15 from the lower part, without lifting the forged round high, reducing the labor intensity of loading and unloading the forged round.

[0040] After the supporting unit 15 is loaded through the traction unit 14, the lower part of the expansion blocking sheet 120 is in contact with the workbench, so that the forged round to be polished is driven into the recessed opening 18 from the inclined table 121, during which the forged round is pressed onto the upper part of the constraint blocking table 122, and then the constraint blocking table 122 is displaced downward, and when the movable sheet 128 is displaced downward into the buckling opening 127, the forged round is displaced across the constraint blocking table 122 into the recessed opening 18, and the forged round is prevented from moving away through the constraint blocking table 122, and then the supporting unit 15 is returned to the initial position through the motor 130, so that the forged round is limited on the supporting ball 19 at the lower part of the recessed opening 18, and the two ends of the forged round are prevented from moving through the constraint module 16.

[0041] The constraint module 16 comprises a rod body 140 and a plug tube 143. The wall of the rod body 140 is provided with a thread. One end of the extension seat 126 is provided with a vertical piece 138. The upper part of the vertical piece 138 is provided with a female thread 139. The inside of the female thread 139 is provided with the rod body 140. One end of the rod body 140 is provided with a rotating handle 141. The other end of the rod body 140 is provided with a rotary bearing 142. One end of the plug tube 143 is open. The other end of the plug tube 143 is provided with a contact piece 145. The peripheral wall of the plug tube 143 is provided with a sprocket X 144. The rod body 140 is clamped into the inside of the plug tube 143 through the rotary bearing 142 at one end. The centers of the rod bodies 140 on the two constraint modules 16 are in a straight line. The sprocket X 144 is connected with the external motor X through a chain.

[0042] After the forged round is loaded into the inside through the inside recess 18 in the two supporting units 15, the two constraint fitting surfaces and the center of the forged round are aligned, so that the subsequent polishing operation of the forged round is more stable.

[0043] The rod body 140 is rotated by pulling the rotating handle 141. The rod body 140 moves along the inside of the female thread 139. One end of the rod body 140 is in contact with the inside of the plug tube 143 through the rotary bearing 142. Thus, the contact piece 145 at one end of the plug tube 143 is limited to the head of the forged round during the movement of the rod body 140. The forged round is stably loaded in the inside and is rotated. The sprocket X 144 on the plug tube 143 is rotated by the cooperation of the motor X and the chain, so that the forged round is rotated stably in the inside.

[0044] During the movement of the supporting unit 15 in the lower position of the forged round, the constraint module 16 is released first, and then the supporting unit 15 is displaced by the pulling unit 14.
