A surface treatment device for forging processing

Abstract

The present invention relates to the technical field of forging surface polishing, and particularly relates to a surface treatment device for forging processing. The technical problem is that when the current treatment device polishes a forging, it is not convenient to adjust the polishing radius of the polishing roller, and thus it is difficult to polish forgings of different sizes. Moreover, the groove heights on forgings of different sizes are inconsistent, and the existing treatment device is difficult to position the heights of the grooves on forgings of different sizes, resulting in the polishing ring of the polishing roller being unable to polish the middle groove of the forging more precisely, thereby leading to a poor polishing effect on the forging surface. A surface treatment device for forging processing includes a frame, a support column is fixedly connected to the middle of the frame, and a center frame is rotatably connected to the frame. The unfolding angle of the rotating arm can be adjusted by a second adjusting screw according to the size of the forging, so as to adjust the polishing radius, and thus it is possible to polish forgings of different sizes, thereby enhancing the polishing effect on the forging surface.

Description

Technical Field

[0001] The present invention relates to the technical field of workpiece polishing equipment, and particularly relates to a surface treatment device for forging processing. Background Art

[0002] When producing a crimp-type mechanical connector, in order to improve the strength of the jaws, the jaws are produced by forging. After the jaws of the crimp-type mechanical connector are forged and formed, the inner surface of the jaw forging is relatively rough and needs to be polished. When polishing the inner side of the jaw forging, the pin hole of the jaw forging is fixed by a support arm with adjustable spacing, and then the forging is resisted by a limiting rod, so as to fix forgings of different sizes. Subsequently, the inner surface of the jaw forging is polished by the polishing roller of the treatment device.

[0003] Since the radius lengths of forgings of different sizes are inconsistent, and the current treatment device is not convenient to adjust the polishing radius of the polishing roller when polishing the forging, it is difficult for the polishing roller to polish the surfaces of forgings of different sizes. Moreover, it is more important to polish the middle groove of the forging, and the groove heights of forgings of different sizes are inconsistent when placed on the same plane. At present, it is difficult for the treatment device to position the height of the forging groove, resulting in inaccurate polishing of the forging groove by the polishing ring of the polishing roller, thus leading to poor polishing effect on the forging surface. Summary of the Invention

[0034] Embodiment 1: A surface treatment device for forging processing, as Figures 1-14 shown, includes a frame 1. A support column 2 is connected to the middle of the frame 1 through a keyway.

A polishing roller 6 is connected to each of the four rotating shafts 5 through a keyway. A polishing ring is provided in the middle of the polishing roller 6. A motor 7 is connected to the bottom of the frame 1 through bolts. A first gear 8 is connected to the output shaft of the motor 7 through a keyway.

A forging 1041 is placed on the clamping mechanism. The polishing roller 6 is used to polish the forging 1041. The polishing ring of the polishing roller 6 is used to polish the middle groove of the forging 1041. The clamping mechanism is used to clamp the forging 1041. A self-rotation mechanism for enabling the polishing roller 6 to rotate by itself is provided on the support column 2. An angle mechanism for rotating the rotating frame 4 is provided on the rotating frame 4.

[0035] The clamping mechanism includes a support frame 101, which is connected to the top end of the frame 1 near the motor 7 by bolts. A sliding seat 102 is slidably connected to the support frame 101. A first adjusting screw 103 is rotatably connected to the support frame 101. The first adjusting screw 103 is threadedly connected to the sliding seat 102. Two rotating arms 104 are rotatably connected to the sliding seat 102. The tops of the two ends of the two rotating arms 104 away from each other are rod-shaped structures. The rod-shaped structures of the rotating arms 104 are used to insert into the pin holes of the forging 1041. The two rotating arms 104 are symmetrically arranged. A hydraulic rod 106 is connected to the middle of the sliding seat 102 by bolts. A limiting rod 107 is slidably connected to the top of the sliding seat 102. The limiting rod 107 is used to abut against the forging 1041. The limiting rod 107 is slidably connected to the telescopic rod of the hydraulic rod 106. A tension spring 108 is connected between the end of the limiting rod 107 away from the frame 1 and the telescopic rod of the hydraulic rod 106.

[0036] It further includes two half gears 105, which are respectively connected to the ends of the two rotating arms 104 close to each other by bolts. The two half gears 105 are meshed with each other. The half gears 105 are used to keep the center of the forging 1041 always on the axis of the subsequent moving direction of the forging 1041.

[0037] It further includes a contact pad 109, which is connected to the end of the limiting rod 107 close to the frame 1. The contact pad 109 is used to prevent the limiting rod 107 from damaging the forging 1041.

[0038] The self-rotation mechanism includes a third gear 111, which is connected to the top of the support column 2 through a keyway. The tops of the four rotating frames 4 are all rotatably connected with a fourth gear 112. The four fourth gears 112 are all meshed with the third gear 111. The bottoms of the four fourth gears 112 are all connected with a first transmission wheel 113 by bolts. The fourth gear 112 drives the first transmission wheel 113 to rotate through the third gear 111. The tops of the four rotating shafts 5 are all connected with a second transmission wheel 115 through a keyway. Transmission belts 114 are wound between the four second transmission wheels 115 and the four first transmission wheels 113 respectively.

[0039] The angle mechanism includes a spatial cam 121. The four spatial cams 121 are respectively connected to the middle parts of the four rotating frames 4 by bolts. A spiral groove is formed on the spatial cam 121. A lifting ring 122 is slidably connected to the middle part of the support column 2. A second adjusting screw 123 is rotatably connected inside the support column 2. The second adjusting screw 123 is threadedly connected to the lifting ring 122. Four guide rods 124 are evenly connected to the center frame 3 by bolts. A synchronous ring 125 is slidably connected between the four guide rods 124. Four guide columns are provided on the synchronous ring 125. The guide columns of the synchronous ring 125 drive the rotating frame 4 to swing by squeezing the spiral groove of the spatial cam 121. A rotational connection is provided between the synchronous ring 125 and the lifting ring 122. The four guide columns of the synchronous ring 125 are respectively slidably connected to the spiral grooves of the four spatial cams 121.

[0040] First, the operator rotates the rotary arm 104 according to the size of the forging 1041 to be polished. When one rotary arm 104 is rotated, the rotary arm 104 will drive the other rotary arm 104 to rotate by the same angle through two half gears 105. When the distance between the rod-shaped structures of the two rotary arms 104 is the same as the distance between the pin holes at both ends of the forging 1041, then align the pin holes of the forging 1041 with the rod-shaped structures of the two rotary arms 104 and place the forging 1041 on the two rotary arms 104. In this way, the two rotary arms 104 are kept symmetrical through the two half gears 105. Furthermore, the centers of forgings 1041 of different sizes will always be located on the axis of the subsequent moving direction of the forging 1041. Then, the operator controls the telescopic rod of the hydraulic rod 106 to retract towards the forging 1041. The retraction of the telescopic rod of the hydraulic rod 106 will pull the limit rod 107 to move towards the forging 1041 through the tension spring 108. Subsequently, the limit rod 107 will abut against the forging 1041 through the contact pad 109. Furthermore, the forging 1041 is prevented from being bruised through the contact pad 109. The telescopic rod of the hydraulic rod 106 continues to retract, and the tension spring 108 is stretched. The tension of the tension spring 108 continuously exerts pressure on the forging 1041 through the limit rod 107. In this way, after the rotary arm 104 with adjustable distance supports the forging 1041, the limit rod 107 that automatically adapts to the distance abuts against the forging 1041. Furthermore, forgings 1041 of different sizes can be fixed, and thus the forging 1041 is more stable during the subsequent polishing process, thereby enhancing the polishing effect of the processing device on the surface of the forging 1041. Then, the operator starts the motor 7. The rotation of the output shaft of the motor 7 will drive the first gear 8 to rotate. The rotation of the first gear 8 will drive the center frame 3 to rotate through the second gear 9. The rotation of the center frame 3 will drive the four rotating frames 4 to rotate, so that the four rotating frames 4 drive the four polishing rollers 6 to rotate respectively through the four rotating shafts 5. While the center frame 3 drives the four rotating frames 4 to rotate, the fourth gears 112 on the four rotating frames 4 will drive the first driving wheels 113 to rotate respectively through the third gears 111. The rotation of the first driving wheels 113 will drive the four second driving wheels 115 to rotate respectively through the four transmission belts 114. The rotation of the four second driving wheels 115 will drive the four polishing rollers 6 to rotate respectively through the four rotating shafts 5. In this way, while the center frame 3 drives the polishing rollers 6 to rotate, the polishing rollers 6 are driven to rotate by themselves through the second driving wheels 115. Furthermore, the friction between the polishing rollers 6 and the forging 1041 is strengthened, and thus the polishing rollers 6 can better polish the forging 1041, thereby improving the polishing efficiency of the processing device on the surface of the forging 1041.When the inner diameter of the forging 1041 is relatively large, the operator rotates the second adjusting screw 123. The rotation of the second adjusting screw 123 will drive the synchronous ring 125 to move downward through the lifting ring 122. The downward movement of the synchronous ring 125 will drive the four rotating frames 4 to rotate outward and expand respectively through the four spatial cams 121, so that the polishing radius of the four polishing rollers 6 increases. When the inner diameter of the forging 1041 is relatively small, the operator rotates the second adjusting screw 123 in the reverse direction. The reverse rotation of the second adjusting screw 123 will drive the synchronous ring 125 to move upward through the lifting ring 122. The upward movement of the synchronous ring 125 will drive the four rotating frames 4 to rotate inward and contract respectively through the four spatial cams 121, so that the polishing radius of the four polishing rollers 6 decreases. In this way, the expansion angle of the rotating arm 104 can be adjusted by the second adjusting screw 123 according to the size of the forging 1041, and then the polishing radius of the polishing roller 6 can be adjusted, so that the polishing roller 6 can polish the surface of forgings 1041 of different sizes, thereby further enhancing the polishing effect of the processing device on the surface of the forging 1041. Subsequently, the operator drives the sliding seat 102 to move towards the frame 1 by rotating the first adjusting screw 103. The movement of the sliding seat 102 will drive the forging 1041 to approach the polishing roller 6 through the two rotating arms 104, and then polish the forging 1041. After the polishing is completed, the operator turns off the motor 7, and then rotates the first adjusting screw 103 in the reverse direction to reset the sliding seat 102. The reset of the sliding seat 102 will drive the forging 1041 to reset through the rotating arm 104. Subsequently, the operator controls the telescopic rod of the hydraulic rod 106 to extend and reset, and the tension spring 108 resets. After the telescopic rod of the hydraulic rod 106 extends, it will push the limiting rod 107 to reset, so that the limiting rod 107 no longer abuts against the forging 1041. Then the operator can remove the forging 1041.;

[0041] Embodiment 2: On the basis of Embodiment 1, as Figures 1-13As shown, it further includes a central mechanism, which is arranged on the limiting rod 107. The central mechanism is used to position the forging 1041. The central mechanism includes a support rod 131, and the support rod 131 is connected to one end of the limiting rod 107 close to the contact pad 109 by bolts. Both the upper and lower ends of the support rod 131 are slidably connected with positioning blocks 132. The positioning blocks 132 are used to position the forging 1041. The two positioning blocks 132 are symmetrically arranged. Pressure springs 133 are respectively connected between the two positioning blocks 132 and the support rod 131 on the sides where they are close to each other. The two pressure springs 133 are symmetrically arranged. Link rods 134 are respectively rotatably connected to both sides of the two positioning blocks 132. The two link rods 134 on the same side are in a group, and there are two groups of link rods 134 in total. The two link rods 134 in the same group are symmetrically arranged. The two groups of link rods 134 are symmetrically arranged. A sliding rod 135 is rotatably connected between the two link rods 134 in each group. The two sliding rods 135 are symmetrically arranged. The sliding rod 135 drives the positioning block 132 to move by pulling the link rod 134. One end of the limiting rod 107 away from the frame 1 is rotatably connected with a support shaft 136. Both ends of the support shaft 136 are connected with wire winding wheels 137 through key grooves. A connecting block 138 is connected to the top of the telescopic rod of the hydraulic rod 106 by bolts. Two steel wire ropes 139 are connected to one side of the connecting block 138 close to the wire winding wheel 137. The two steel wire ropes 139 respectively bypass the two wire winding wheels 137 and are connected to the two sliding rods 135.

[0042] After the telescopic rod of the hydraulic rod 106 drives the limit rod 107 to abut against the forging 1041 through the tension spring 108, the telescopic rod of the hydraulic rod 106 continues to move in the direction close to the forging 1041. The continuous movement of the telescopic rod of the hydraulic rod 106 will pull the steel wire rope 139 through the connecting block 138, so that the steel wire rope 139 will pull the sliding rod 135 away from the forging 1041 through the wire winding wheel 137. The movement of the sliding rod 135 will pull the two positioning blocks 132 close to each other through the connecting rod 134, and the compression spring 133 will be compressed. The mutual approach of the two positioning blocks 132 will contact the forging 1041 from the upper and lower sides, so that the forging 1041 moves to the middle position. In this way, after clamping the forging 1041, the forging 1041 is moved to the middle position by the two positioning blocks 132, and then the height of the groove of the forging 1041 is positioned, so that the polishing ring of the polishing roller 6 polishes the groove of the forging 1041 more precisely, thereby further enhancing the polishing effect of the processing device on the surface of the forging 1041; after polishing, the telescopic rod of the hydraulic rod 106 resets and no longer pulls the steel wire rope 139 through the connecting block 138, and the compression spring 133 resets to make the two positioning blocks 132 reset. The reset of the positioning block 132 will pull the sliding rod 135 to reset through the connecting rod 134, so that the steel wire rope 139 returns to the initial state.

[0043] Embodiment 3: On the basis of Embodiment 2, as Figures 1-14 shown, it further includes a shielding mechanism. The shielding mechanism is arranged on the frame 1. The shielding mechanism is used to shield the splashing debris. The shielding mechanism includes a shielding cover 141. The shielding cover 141 is connected to the frame 1 by bolts. The shielding cover 141 is used to shield the debris splashing when polishing the forging 1041. The top of the support rod 131 is connected with a support seat 142 by bolts. A shielding cover 143 is rotatably connected to the support seat 142. The shielding cover 143 is used to shield the debris splashing when polishing the forging 1041. A contact frame 144 is connected to the positioning block 132 at a high position by bolts. The contact frame 144 contacts the shielding cover 143.

[0044] The shielding cover 141 and the shielding cover 143 are made of acrylic material. The shielding cover 141 and the shielding cover 143 made of acrylic material are used to observe the polishing situation while shielding.

[0045] It also includes a sliding frame 15, which is slidably connected to the shielding cover 141, and has two through holes in it. A handle 16 is connected between the two ends of the sliding frame 15 away from the support column 2, and a shunt pipe 17 is connected between the two ends of the sliding frame 15 close to the handle 16. The shunt pipe 17 is used to divert the polishing agent, and a brush strip 18 is connected to the end of the sliding frame 15 away from the shunt pipe 17. The brush strip 18 is used to apply the polishing agent to the polishing roller 6.

[0046] At first, the contact frame 144 is against the shielding cover 143, so that the shielding cover 143 is in an open state. When the positioning block 132 moves downward to position the forging 1041, the contact frame 144 will be driven to move downward, so that the contact frame 144 no longer resists the shielding cover 143. The shielding cover 143 is supported by the end of the support seat 142 close to the forging 1041 after rotating downward by 90 degrees through the center of gravity. Then, when the operator moves the sliding seat 102 to drive the forging 1041 to polish, the shielding cover 143 will move in the direction close to the shielding cover 141 and then align with the shielding cover 141. In this way, when the forging 1041 is polished, it is shielded by the acrylic shielding cover 141 and the shielding cover 143, so that the debris can be blocked and observed at the same time, so that the polishing process of the forging 1041 can be targetedly adjusted to the polishing condition, thereby further enhancing the polishing effect of the processing device on the surface of the forging 1041; during polishing, the operator The operator connects the polishing agent feeding pump to the shunt pipe 17. After the operator starts the feeding pump, the feeding pump will pump the polishing agent into the through hole of the sliding frame 15 through the shunt pipe 17. Then the polishing agent will adhere to the brush strip 18 through the through hole of the sliding frame 15. Then the operator moves the position of the sliding frame 15 through the handle 16, so that the center frame 3 drives the polishing roller 6 to rotate and contact with the brush strip 18. In this way, the center frame 3 drives the polishing roller 6 to rotate and contact with the brush strip 18 with the polishing agent attached, and then the polishing agent is applied to the polishing roller 6, so that the polishing roller 6 can better polish the forging 1041 with the polishing agent, thereby further enhancing the polishing effect of the processing device on the surface of the forging 1041; after the polishing agent is applied, the operator turns off the feeding pump. After polishing is completed, the positioning block 132 is reset to drive the contact frame 144 to reset. The reset of the contact frame 144 will squeeze the bottom of the shielding cover 143, so that the shielding cover 143 rotates upward and opens to return to the initial state.

[0047] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
