Description

Technical Field

[0001] The present invention relates to the field of alloy plate processing, in particular to a tin-zinc-copper alloy plate rolling processing device. Background Art

[0002] A metal rolling machine is a mechanical device used to plastically deform metal materials through one or more pairs of rotating rollers, thereby changing their shape, size and properties.

[0003] When people need to press thick alloy plates into thin plates, they can use a rolling press to operate. First, people start the rolling press to rotate one or more pairs of rollers on the rolling press. Then people pass the metal plates to be rolled through the rollers. Because the distance between each pair of rollers is adjusted in advance, the plates are pressed into thinner plates after passing through the rollers. When people need to roll thicker plates into thinner plates, they need to roll them in multiple times. If people want to roll them into place at one time, it may cause rolling difficulties, and even cause the plates to get stuck between the rollers. Each time the sheet is rolled, it is only rolled a short distance. After each rolling, people need to take out the rolled sheet, and then further adjust the distance between the rollers, and finally send the sheet back between the rollers for rolling. In this way, the rolling operation is repeated many times to finally achieve the desired sheet thickness. In the process of repeated rolling, the existing device requires people to manually send the sheet back between the rollers each time, which is time-consuming and labor-intensive. Therefore, a tin-zinc-copper alloy sheet rolling processing device is designed, which can automatically send the sheet between the rollers during the repeated rolling process, and no longer requires people to manually feed the sheet each time.

A self-locking device is provided inside the second adjusting gear disc 14, and the self-locking device clamps the second adjusting gear disc 14 through a buckle, so that the second adjusting gear disc 14 does not rotate easily.

[0042] When people need to perform rolling work on the tin-zinc-copper alloy plate, they can use this device to operate it. First, people fix the right part of the tin-zinc-copper alloy plate to be rolled between the right clamping plate 16 and the sliding plate 162, and manually align the tin-zinc-copper alloy plate so that the tin-zinc-copper alloy plate can face the roller 12. Then manually rotate the second adjusting toothed disc 14, and the second adjusting toothed disc 14 drives the first adjusting toothed disc 13 to rotate. The first adjusting toothed disc 13 drives the first screw 131 to rotate. The first screw 131 drives the sliding frame 1102 and then drives the upper roller 12 to move up and down, thereby adjusting the distance between the two rollers 12 so that the distance between the rollers 12 is smaller than the thickness of the tin-zinc-copper alloy plate. Because the moving component is provided with a self-locking device inside, Therefore, during the rolling work, the upper roller 12 will not move upward due to the squeezing of the tin-zinc-copper alloy sheet, and the upper roller 12 will not move downward due to its own weight, which will lead to a poor rolling effect. Then start the transmission motor 113 and the right drive motor 18 to rotate forward, and the right drive motor 18 drives the right second screw 19 to rotate clockwise. The right second screw 19 is threadedly connected to the second connecting rod 111, so that the second connecting rod 111 drives the right sliding plate 162 and then drives the right splint 16 to move to the left. The right splint 16 drives the tin-zinc-copper alloy sheet to move to the left. At the same time, the output shaft of the transmission motor 113 drives the upper roller 12 to rotate, and people manually drive the tin-zinc-copper alloy The left part of the plate moves to the left. When the tin-zinc-copper alloy plate contacts the roller 12, the roller 12 will drive the tin-zinc-copper alloy plate to move to the left through friction, so that the tin-zinc-copper alloy plate passes between the rollers 12, so that the roller 12 extends the tin-zinc-copper alloy plate. The tin-zinc-copper alloy plate will drive the roller 12 below to rotate, and the tin-zinc-copper alloy plate is extended and thinned. When the left part of the tin-zinc-copper alloy plate contacts the left splint 16, people control the left drive motor 18 to reverse, and the drive motor 18 drives the left second screw 19 to rotate counterclockwise. The second screw 19 drives the first connecting rod 110 and then drives the left sliding plate 162 to move to the left. The left sliding plate 162 drives the left splint 16 to move to the left, and the long rod on the left splint 16 Disengaged from the positioning frame 112, the compression spring 161 on the left is reset from the compressed state, and the compression spring 161 on the left drives the left clamping plate 16 to move downward, so that the left part of the tin-zinc-copper alloy plate is fixed between the left clamping plate 16 and the sliding plate 162. The left clamping plate 16 moves to the left, driving the left part of the tin-zinc-copper alloy plate to move to the left. When the long rod on the right clamping plate 16 is about to contact the right positioning frame 112, people manually rotate the second adjusting toothed disc 14, and the second adjusting toothed disc 14 drives the first adjusting toothed disc 13 to rotate, and the first adjusting toothed disc 13 drives the first screw 131 to rotate, and the first screw 131 drives the sliding frame 1102 and then drives the upper roller 12 to move downward, so that the distance between the two rollers 12 is further reduced.At this time, the long rod on the right splint 16 has not yet contacted the right clamping frame 112, and then people turn and control the left drive motor 18 to rotate forward, the left drive motor 18 rotates forward to drive the left second screw 19 to rotate forward, the left second screw 19 drives the first connecting rod 110 and then drives the left sliding plate 162 to move right, the left sliding plate 162 drives the left splint 16 to move right, control the right drive motor 18 to reverse, the right drive motor 18 reverses to drive the right second screw 19 to reverse, the right second screw 19 drives the second connecting rod 111 and then drives the right sliding plate 162 to move right, and the right sliding plate 162 drives the right splint 16 to move right The two clamping plates 16 jointly drive the tin-zinc-copper alloy sheet to move to the right, so that the tin-zinc-copper alloy sheet is once again rolled and thinned, and then the above operation is repeated many times, so that the tin-zinc-copper alloy sheet moves back and forth between the two rollers 12 and is repeatedly rolled. Whenever the tin-zinc-copper alloy sheet passes through the gap between the rollers 12 from right to left, people need to first rotate the second adjusting toothed disc 14. The second adjusting toothed disc 14 drives the first adjusting toothed disc 13 and then drives the first screw 131 to rotate. The first screw 131 drives the sliding frame 1102 and then drives the upper roller 12 to move downward, so that the distance between the upper and lower rollers 12 is gradually reduced, so that the tin-zinc-copper alloy sheet is gradually rolled and thinner. , until the thickness of the tin-zinc-copper alloy sheet is extended to the specified thickness. When the tin-zinc-copper alloy sheet is extended, people control the left drive motor 18 to reverse and the right drive motor 18 to rotate forward, so that the two clamping plates 16 drive the tin-zinc-copper alloy sheet to move to the left, so that the long rod on the right clamping plate 16 contacts and squeezes the right clamping frame 112, so that the right clamping plate 16 is squeezed and moves upward, the right compression spring 161 is compressed, and the right clamping plate 16 releases the right part of the tin-zinc-copper alloy sheet, and then turn off the right drive motor 18, and the left clamping plate 16 drives the tin-zinc-copper alloy sheet to continue to move to the left until the tin-zinc-copper alloy sheet completely passes through between the rollers 12 to the left, and then The left drive motor 18 is turned off, and the tin-zinc-copper alloy sheet that has been rolled is manually removed. This is done by rotating the second adjustment gear disc 14, which in turn drives the first adjustment gear disc 13, which in turn drives the first screw 131 to rotate. The first screw 131 drives the slide frame 1102, which in turn drives the rollers 12 above it to move up and down, thereby adjusting the distance between the two rollers 12. By providing two left and right drive motors 18, each controlling the left and right sliding plates 162 to slide on the guide plate 15, the sliding plates 162 drive the tin-zinc-copper alloy sheet to continuously move left and right between the rollers 12, thereby replacing the manual feeding of the tin-zinc-copper alloy sheet into the rolling press.

[0043] During the continuous rolling process of the sheet, the thickness of the sheet will gradually become thinner, causing the length of the sheet to be gradually lengthened. If the distance between the two clamps 16 remains unchanged, the elongated part of the sheet will become loose or even curl. Therefore, during the continuous rolling process of the tin-zinc-copper alloy sheet, the distance between the two clamps 16 needs to be continuously adjusted and lengthened, because the tin-zinc-copper alloy sheet will only become thinner when it is rolled and thinned. In order to make the tin-zinc-copper alloy sheet be rolled more evenly, people will adjust the roller 12 only after the tin-zinc-copper alloy sheet is rolled from right to left. After adjustment, the two clamping plates 16 drive the tin-zinc-copper alloy sheet to move from left to right. The tin-zinc-copper alloy sheet is stretched and pressed to become thinner and longer. Therefore, when the tin-zinc-copper alloy sheet moves from left to right, people first turn off the left drive motor 18 for 2-3 seconds to achieve the purpose of lengthening the distance between the two clamping plates 16, so as to adapt to the lengthening of the tin-zinc-copper alloy sheet. The tin-zinc-copper alloy sheet is clamped between the two clamping plates 16, and the distance between the two clamping plates 16 is lengthened, which can prevent the middle part of the tin-zinc-copper alloy sheet from becoming loose or even curling after it becomes longer.

[0044] Example 2: Based on Example 1, please refer to Figure 7-Figure 9 , and also includes a distance adjusting mechanism that can continuously adjust the gap between the two rollers during the rolling process. The distance adjusting mechanism includes ten rotating blocks 22. The rotating blocks 22 are all circumferentially fixed on the second adjusting gear disk 14. A push rod 21 is slidingly connected to the upper side of the fixed frame 1101. A return spring 24 is fixed between the push rod 21 and the fixed frame 1101. The push rod 21 is connected to an extrusion component that can squeeze the rotating block 22.

[0045] See also Figure 7-Figure 8 , also includes a pressing rod 2, which is fixed to the upper side of the sliding plate 162 on the right, and the upper part of the pressing rod 2 is squeezed and matched with the right side of the push rod 21.

[0046] See also Figure 9 The extrusion assembly includes a locking block 23, which is slidably connected to the push rod 21. The left side of the locking block 23 is a right-angled surface, and the right side is an inclined surface. The locking block 23 and the rotating block 22 are both squeezed together, and a pressure spring 231 is fixed between the locking block 23 and the push rod 21.

[0047] Each time the tin-zinc-copper alloy sheet is rolled, people need to manually adjust the distance between the rollers 12 many times, which is troublesome. Therefore, a distance adjustment mechanism is provided that can automatically adjust the distance between the rollers 12. The working principle is as follows: Whenever the right sliding plate 162 drives the tin-zinc-copper alloy sheet to move to the left, the sliding plate 162 drives the pressing rod 2 to move to the left, and the pressing rod 2 contacts and squeezes the push rod 21. At this time, the long rod on the right splint 16 does not contact the right clamping frame 112, and the push rod 21 is The pressing rod 2 is squeezed and moved to the left, the return spring 24 is compressed, and the push rod 21 drives the blocking block 23 to move to the left. The right-angled surface of the blocking block 23 squeezes the rotating block 22, so that the rotating block 22 is squeezed and drives the second adjusting toothed disc 14 to rotate a certain angle, so that the second adjusting toothed disc 14 drives the first adjusting toothed disc 13 and then drives the first screw 131 to rotate, so that the sliding frame 1102 moves downward a certain distance, and the sliding frame 1102 drives the roller 12 to move downward, so that the distance between the rollers 12 is reduced. The distance between the two ends of the tin-zinc-copper alloy sheet is gradually reduced, which can make the tin-zinc-copper alloy sheet gradually thinner by being stretched. When the blocking block 23 is separated from the rotating block 22, the reset spring 24 resets and drives the push rod 21 to drive the blocking block 23 to move right and reset, so that the inclined surface of the blocking block 23 contacts and squeezes the next rotating block 22. The blocking block 23 is squeezed and moves backward, and the pressure spring 231 is squeezed. When the blocking block 23 is separated from the rotating block 22, the pressure spring 231 resets and drives the blocking block 23 to move forward and reset. The above operation is performed by pressing the rod 2 The push rod 21 is squeezed to the left, so that the push rod 21 drives the blocking block 23 to move to the left, and the blocking block 23 squeezes the rotating block 22 to the left, so that the rotating block 22 drives the second adjusting toothed disc 14 to rotate, and the second adjusting toothed disc 14 drives the first adjusting toothed disc 13 and then drives the first screw 131 to rotate, so that the sliding frame 1102 moves downward, thereby achieving the purpose of replacing people's manual adjustment of the distance between the rollers 12, so that the tin-zinc-copper alloy sheet can be rolled thinner, and manual adjustment is no longer required, which is more time-saving and labor-saving.

[0048] See also Figure 10-14The trolley 33 is fixed to the front of the lifting rod 34, and the lifting rod 33 is fixed to the front of the lifting rod 34.

[0049] See also Figure 12 , also includes a limit plate 37, the limit plate 37 is fixed on the upper left side of the chassis 1, and the discharge rod 33 slides on the limit plate 37.

[0050] In order to make people's operation simpler and more convenient, a discharge mechanism is provided which can automatically unload the tin-zinc-copper alloy plate. The working principle is as follows: when people need to unload the tin-zinc-copper alloy plate, the tin-zinc-copper alloy plate is clamped on the left clamping plate 16. People start the pushing motor 35. The output shaft of the pushing motor 35 drives the screw rod 39 to rotate forward. The screw rod 39 is threadedly connected to the lifting rod 34, so that the lifting rod 34 moves backward. The lifting rod 34 contacts and squeezes the short rod on the left clamping plate 16, so that the left clamping plate 16 is squeezed and moves upward. The compression spring 161 on the left is compressed, and the left clamping plate 16 releases the clamping of the tin-zinc-copper alloy plate. At the same time, the lifting rod 34 drives the discharge rod 33 to move backward. The discharge rod 33 pushes the tin-zinc-copper alloy plate that has been clamped backward. The zinc-copper alloy sheet is pushed into the placement frame 31, thereby completing the unloading of the tin-zinc-copper alloy sheet. Then people will push the motor 35 to reverse, and push the motor 35 to drive the screw rod 39 to reverse, so that the lifting rod 34 drives the unloading rod 33 to move forward and reset. When the lifting rod 34 is disengaged from the short rod on the left clamping plate 16, the compression spring 161 on the left is reset and drives the clamping plate 16 to move downward and reset. Then people will push the motor 35 to close. The above operation drives the screw rod 39 to rotate by pushing the motor 35, so that the lifting rod 34 drives the unloading rod 33 to move backward, and the unloading rod 33 squeezes the clamping plate 16, so that the clamping plate 16 releases the clamping of the tin-zinc-copper alloy sheet. The lifting rod 34 pushes the tin-zinc-copper alloy sheet backward, so that the tin-zinc-copper alloy sheet is pushed into the placement frame 31, thereby completing the automatic unloading of the tin-zinc-copper alloy sheet.

[0051] See also Figure 15-17, and also includes a correction mechanism that can correct the tin-zinc-copper alloy plate before the right clamping plate 16 clamps the tin-zinc-copper alloy plate. The correction mechanism includes two first extrusion pieces 41, which are respectively fixed to the front and rear sides of the right side of the right sliding plate 162. The left side of the first extrusion piece 41 close to each other is provided with a trapezoidal protrusion, and the left and right sides of the trapezoidal protrusion are both set as inclined surfaces. A second extrusion piece 42 is fixed on the upper right side of the right guide plate 15, and the second extrusion piece 42 is squeezed and matched with the long rod on the right clamping plate 16. A fixing rod 43 is fixed on the lower side of the right guide plate 15, and the front and rear sides of the fixing rod 43 are slidably connected with the correction piece 4, and a return spring 44 is fixed between the correction piece 4 and the right guide plate 15. Short columns are provided on the upper part of the correction piece 4, and the short columns are squeezed and matched with the trapezoidal protrusions on the corresponding first extrusion pieces 41.

[0052] Because when people fix the tin-zinc-copper alloy plate on the right clamping plate 16, they need to manually adjust the tin-zinc-copper alloy plate so that the tin-zinc-copper alloy plate faces the roller 12. If the tin-zinc-copper alloy plate does not face the roller 12, the direction in which the tin-zinc-copper alloy plate is stretched and lengthened will be offset, so that the stretched tin-zinc-copper alloy plate does not meet the required standards. However, people may not be able to fully align it manually, and manual adjustment is more troublesome. Therefore, a correction mechanism is provided that can automatically correct and align the tin-zinc-copper alloy sheet. The working principle is as follows: people place the tin-zinc-copper alloy sheet that needs to be extended between the right clamping plate 16 and the sliding plate 162, and then people control the right driving motor 18 to rotate forward, and the right driving motor 18 drives the right second screw 19 to rotate clockwise, and the right second screw 19 is threadedly connected to the second connecting rod 111, so that the second connecting rod 111 drives the right sliding plate 162 and then drives the right clamping plate 16 to move to the left, and the right sliding plate 162 pushes the tin-zinc-copper alloy sheet to move to the left, and the right sliding plate 162 drives the first extrusion parts 41 to move to the left, and the first extrusion parts 41 squeeze the corresponding correction parts 4, so that the correction parts 4 move toward the side close to each other, and the correction parts 4 correct and align the tin-zinc-copper alloy sheet, and the right clamping plate 16 continues to move to the left. When the right When the long rod on the side clamp 16 is disengaged from the second extrusion piece 42, the correcting piece 4 is in the state of correcting the tin-zinc-copper alloy plate, and the compression spring 161 on the right is reset from the compressed state, and the compression spring 161 on the right drives the right clamp 16 to move downward, so that the tin-zinc-copper alloy plate is clamped between the right clamp 16 and the sliding plate 162, thereby completing the work of automatically aligning the tin-zinc-copper alloy plate, and avoiding the tin-zinc-copper alloy plate from being offset when being extended. The above operation is achieved by setting the first extrusion piece 41, and the right sliding plate 162 drives the first extrusion piece 41 to move to the left, and the first extrusion piece 41 squeezes the corresponding correcting piece 4, so that the correcting pieces 4 move toward the side close to each other, and the correcting piece 4 corrects, aligns and clamps the tin-zinc-copper alloy plate, thereby replacing people manually correcting and aligning the tin-zinc-copper alloy plate, which saves time and effort, and the alignment effect is more accurate.
