[0038] Example 1

[0039] A rolling head device with impact effect, such as Figure 1-4 As shown, it includes a connecting rod 1, a rotating sleeve 2, a sliding rod 4, a supporting frame 5, a rolling member 6, a lateral adjustment mechanism 7 and a shifting mechanism 8. The connecting rod 1 is rotatably connected with the rotating sleeve 2, and the rotating sleeve 2 can rotate on the connecting rod 1. The rotating sleeve 2 can be connected to the transmission components of other equipment. The right part of the rotating sleeve 2 is uniformly provided with first sliding grooves 3 along the circumferential direction, and there are 8 first sliding grooves 3 on the right. The left part of the rotating sleeve 2 is also uniformly provided with first sliding grooves 3 along the circumferential direction, and there are also 8 first sliding grooves 3 on the left. The first sliding grooves 3 on the left and right sides are symmetrical It is configured that the two first slide grooves 3 on the left and right sides correspond to each other, and the two corresponding first slide grooves 3 form a group, which are divided into 8 groups in total. A sliding rod 4 is slidably connected between each group of first slide grooves 3, and a support frame 5 is slidably connected to the sliding rod 4. The sliding rod 4 can guide the support frame 5, and a rolling part 6 is rotatably connected to the support frame 5. When the rolling part 6 rotates, the workpiece is stamped. A lateral adjustment mechanism 7 is provided between the rotating sleeve 2, the support frame 5 and the sliding rod 4, and a shift mechanism 8 is provided between the lateral adjustment mechanism 7 and the connecting rod 1.

[0040] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the lateral adjustment mechanism 7 includes a knob 72, a reciprocating screw 721, a threaded sleeve 73 and a rotating seat 74. The left part of the rotating sleeve 2 is evenly provided with a second sliding groove 71 along the circumferential direction. There are 8 second sliding grooves 71. The second sliding groove 71 is located between the inner sides of the first sliding groove 3 on the left side. The sliding rod 4 is connected with a rotating seat 74. The rotating seat 74 is rotatably connected with a reciprocating screw 721. The rotating seat 74 can guide the reciprocating screw 721. The reciprocating screw 721 is slidingly connected to the second sliding groove 71 respectively. A knob 72 is welded on the left side of the reciprocating screw 721, and the reciprocating screw 721 can be driven to rotate by the knob 72. The reciprocating screw 721 is threadedly connected with a threaded sleeve 73. The threaded sleeves 73 are respectively connected to the support frame 5. The rotation of the reciprocating screw 721 will drive the threaded sleeve 73 to move left and right, thereby adjusting the left and right positions of the rolling member 6.

[0041] like Figure 1 , Figure 8 and Fig. 9 As shown, the shift mechanism 8 includes a gear 81, a sliding frame 82 and an arc-shaped rack 83. The gear 81 is keyed to the right side of the reciprocating screw 721. The rotation of the gear 81 can drive the reciprocating screw 721 to rotate. The sliding frame 82 is slidably connected to the upper part of the connecting rod 1. The connecting rod 1 can guide the sliding frame 82. An arc-shaped rack 83 is welded to the left side of the top of the sliding frame 82, and the arc-shaped rack 83 is meshed with the gear 81.

[0042] When people need to perform rolling strengthening on a workpiece, they can use the present rolling head. First, the connecting rod 1 is installed on the fixed end face, and the right side of the rotating sleeve 2 is installed together with the transmission components on other equipment; in order to be able to change the staggered effect of the rolling parts 6 when they rotate, the spacing between the support frames 5 is adjusted, and the support frames 5 can also be adjusted left and right. The spacing between the rolling parts 6 can be adjusted, thereby changing the staggered effect of the rolling parts 6 when they rotate, so as to facilitate rolling strengthening of the workpiece to different degrees; First, the method of adjusting the left and right positions of the support frames 5 is as follows: first, the sliding frame 82 is moved to the right to drive the arc-shaped rack 83 to move to the right, so that the arc-shaped rack 83 The screw rod 721 is then rotated to rotate, and the screw rod 721 rotates to move the threaded sleeve 73 left and right, and the threaded sleeve 73 moves left and right to move the support frame 5 and the rolling member 6 left and right, so that the left and right positions of the support frame 5 and the rolling member 6 can be adjusted. Second, the spacing between the support frames 5 is adjusted as follows: the sliding rod 4 is slid on the first slide groove 3, driving the support frame 5 and the rolling member 6 to slide, and driving the rotating seat 74, the reciprocating screw 721 and the threaded sleeve 73 to move, so that the spacing between the support frame 5 and the rolling member 6 can be adjusted. The above two steps can change the rotation of the rolling member 6 Staggered effect; then, by starting the transmission component, the rotating sleeve 2 is rotated, and the rotating sleeve 2 drives the sliding rod 4, the supporting frame 5 and the rolling piece 6 to rotate, and the rolling piece 6 is brought close to the workpiece. The rolling piece 6 can continuously hammer the workpiece during the rotation process. Each time the rolling piece 6 contacts the workpiece, a large instantaneous dynamic impact is generated, causing a severe plastic deformation on the surface of the workpiece, making the nanocrystals of the surface tissue of the workpiece finer and the strengthening layer thicker; in order to better plastically deform the workpiece, the rolling piece 6 can automatically move left and right during the rotation process to achieve more effective hammering of the workpiece, and the sliding frame 82 is moved to the left to drive the arc-shaped rack 83 to Move left and mesh with gear 81, then when the sliding rod 4 rotates, it will drive the reciprocating screw 721 and gear 81 to rotate, and the arc rack 83 remains stationary. When the gear 81 and the arc rack 83 are meshed, the gear 81 will drive the reciprocating screw 721 to rotate continuously, so that the threaded sleeve 73 drives the support frame 5 and the rolling part 6 to move left and right. When the gear 81 and the arc rack 83, the rolling part 6 stops moving. Repeat the above operation, the rolling part 6 will move left and right intermittently, which can continuously change the staggered effect of the rolling part 6 when it rotates, so that the workpiece can be better plastically deformed. When not in use, the transmission assembly can be closed and the connecting rod 1 can be removed.

[0043] Example 2

[0044] On the basis of Example 1, Figure 1 , Figure 4 , Fig.10 and Fig.11As shown, it also includes a limiting mechanism 9, which includes a first pressing block 91, a limiting frame 92, a wedge block 93, a first spring 94 and a second spring 95. The right part of the sliding frame 82 is slidably connected with the wedge block 93, and a first spring 94 is connected between the bottom of the wedge block 93 and the sliding frame 82. The first spring 94 can drive the wedge block 93 to move and reset. A first pressing block 91 is welded on the right side of the wedge block 93, and the wedge block 93 can be driven to move downward through the first pressing block 91. The right side of the bottom of the connecting rod 1 is connected to the limiting frame 92 by bolts, and the limiting frame 92 can limit the wedge block 93. A second spring 95 is connected between the right side of the limiting frame 92 and the right part of the sliding frame 82, and the second spring 95 can drive the sliding frame 82 to move and reset.

[0045] If it is necessary to move the arc-shaped rack 83 to the right and separate the gear 81, the sliding frame 82 can be pulled to the right, and the sliding frame 82 drives the arc-shaped rack 83 and the wedge block 93 to move to the right, and the second spring 95 is stretched. When the right side of the wedge block 93 contacts the limiting frame 92, the wedge block 93 and the first pressing block 91 move downward, and the first spring 94 is compressed. When the wedge block 93 moves to the right side of the limiting frame 92, under the action of the first spring 94, the wedge block 93 and the first pressing block 91 move upward and reset. At this time, the limiting frame 92 can limit the wedge block 93, which can prevent the sliding frame 82 and the arc-shaped rack 83 from re-engaging. Move it to the left to reset, and then people can adjust the left and right positions of the rolling member 6; if it is necessary to mesh the arc-shaped rack 83 and the gear 81, the first pressing block 91 can be moved downward to drive the wedge block 93 to move downward, and the first spring 94 is compressed, so that the wedge block 93 and the limiting frame 92 are separated, and then under the action of the second spring 95, the sliding frame 82 drives the arc-shaped rack 83, the wedge block 93 and the first pressing block 91 to move to the left to reset, the arc-shaped rack 83 and the gear 81 are re-engaged, and the first pressing block 91 is released, and under the action of the first spring 94, the wedge block 93 and the first pressing block 91 move upward to reset.

[0046] like Figure 1 , Figure 4 , Fig.12 , Fig.13 and Fig.14As shown, a rotation adjustment mechanism 10 is also included, which includes a fixed arc block 101, a slot 102, a sliding block 103, a sleeve 104, a second pressing block 105 and a third spring 106. The left and right sides of the rotating sleeve 2 are connected with fixed arc blocks 101, and 8 groups of slots 102 are evenly opened on the fixed arc block 101, each group has 3 slots 102. Sleeves 104 are welded on the left and right sides of the sliding rod 4. Sliding blocks 103 are slidably connected in the sliding sleeves 104. The sliding sleeves 104 guide the sliding blocks 103. The sliding blocks 103 can be respectively inserted into the slots 102. The third spring 106 is connected between the sliding blocks 103 and the sleeves 104. The third spring 106 can drive the sliding blocks 103 to move and reset. The sliding blocks 103 are welded with second pressing blocks 105, and the sliding blocks 103 can be driven to move by moving the second pressing blocks 105.

[0047] When adjusting the distance between the support frames 5, the second pressing block 105 can be used to first drive the sliding block 103 to move to the side away from the slot 102, so that the sliding block 103 and the slot 102 are separated and the third spring 106 is compressed. Then the sliding rod 4 can be moved and adjusted on the first slide slot 3. When it is adjusted to a suitable position, the second pressing block 105 can be released. Under the action of the third spring 106, the sliding block 103 and the second pressing block 105 are driven to move to the side close to the slot 102, so that the sliding block 103 is stuck in the slot 102. In this way, the position of the sliding rod 4 can be locked, and the distance between the support frame 5 and the rolling member 6 can be adjusted.

[0048] like Figure 1 , Fig.15 , Fig.16 and Fig.17 As shown, it also includes a lubrication mechanism 11, which includes a threaded cover 111, an oil storage tank 112, a one-way air intake valve 113, a hose 114, a pressurizing cylinder 115, a piston rod 116 and an oil outlet pipe 117. The right side of the rotating sleeve 2 is connected to the oil storage tank 112 by bolts. The oil storage tank 112 is used to store lubricating oil. The right side of the oil storage tank 112 is threadedly connected to the threaded cover 111. The top of the oil storage tank 112 is connected to the one-way air intake valve 113. 13. The left part of the oil storage tank 112 is evenly connected with a hose 114 along the circumferential direction. The hose 114 is used to guide the lubricating oil. The support frame 5 is connected with an oil outlet pipe 117. The middle of the oil outlet pipe 117 is provided with a pressurizing cylinder 115. The pressurizing cylinder 115 is connected to the support frame 5. The pressurizing cylinder 115 and the hose 114 are connected and communicated. The pressurizing cylinder 115 is slidably connected with a piston rod 116, and the piston rod 116 slides in the pressurizing cylinder 115.

[0049] like Figure 1 , Figure 4 , Fig.18 and Fig.19 As shown, it also includes a pushing mechanism 12, which includes a cam 121, a bracket 122, a roller 123 and a fourth spring 124. The cam 121 is connected to the middle of the rolling member 6, and the rotation of the rolling member 6 drives the cam 121 to rotate. The bracket 122 is welded on the piston rod 116, and the roller 123 is rotatably connected to the bracket 122. The rotation of the cam 121 will squeeze the roller 123, and the fourth spring 124 is connected between the bracket 122 and the pressure cylinder 115.

[0050] First, open the threaded cover 111, then inject lubricating oil into the oil storage tank 112, and then close the threaded cover 111. Subsequently, when the rolling member 6 rotates with the support frame 5, the rolling member 6 will contact the workpiece, causing the rolling member 6 to rotate. The rotation of the rolling member 6 drives the cam 121 to rotate continuously, and the cam 121 rotates the intermittent extrusion roller 123. When the cam 121 squeezes the roller 123, the roller 123 drives the bracket 122 and the piston rod 116 to move to the side away from the cam 121. The fourth spring 124 is compressed, and the piston rod 116 squeezes the gas in the pressure cylinder 115, and the one-way air intake valve 11 3, the lubricating oil will not be discharged through the one-way air inlet valve 113, the gas will squeeze the lubricating oil into the oil outlet pipe 117 through the hose 114, and finally the lubricating oil will be discharged through the oil outlet pipe 117, the lubricating oil can lubricate the rolling member 6, and can prevent the rolling member 6 from decreasing in rotation speed; when the cam 121 and the roller 123 are separated, under the action of the fourth spring 124, the bracket 122, the piston rod 116 and the roller 123 move and reset, at this time the gas will be discharged into the oil storage tank 112 through the one-way air inlet valve 113, repeating the above operation can achieve the effect of intermittent oil discharge, and can intermittently lubricate the rolling member 6.
