Description

Technical Field

[0001] The present application relates to the field of stamping technology, and in particular to a stamping device. Background Art

[0002] Automobile clamps are generally formed by stamping equipment.

[0003] During production, the staff places the steel coil on the feeding mechanism, which releases the steel coil into a continuous steel strip, and puts the steel strip into the stamping equipment for stamping.

[0004] Regarding the above-mentioned related technologies, when the stamping equipment stamps the steel strip downward, the steel strip in the stamping equipment is fixed, but the feeding mechanism still continuously feeds the stamping equipment, making the steel strip between the feeding mechanism and the stamping equipment easy to bend and deform. Summary of the invention

[0005] In order to prevent the steel strip from being easily bent and deformed, the present application provides a stamping device.

[0006] The present application provides a stamping equipment adopting the following technical solution:

[0007] A stamping device, comprising a feeding mechanism, a leveling mechanism and a stamping mechanism arranged in sequence, wherein the feeding mechanism comprises a feeding frame and a feeding tray for mounting a steel coil, the feeding tray is rotatably connected to the feeding frame, and the stamping mechanism comprises a die table and a stamping head located above the die table;

[0008] The flattening mechanism comprises a straightening section and a conveying section, the straightening section and the conveying section are separated by a distance, the conveying section comprises a bearing seat, an upper pressing roller and a lower active roller, the upper pressing roller and the lower active roller are both rotatably mounted on the bearing seat, and the upper pressing roller and the lower active roller are arranged opposite to each other;

[0009] The conveying section is provided with a separation piece, which includes a rotating shaft rotatably arranged in the bearing seat, a supporting rod fixedly connected to the rotating shaft, and a pressure rod abutting against the punching head, the end of the supporting rod away from the rotating shaft is located below the upper clamping roller, and the pressure rod is fixedly connected to the rotating shaft.

[0010] By adopting the above technical solution, when the stamping equipment is used, the feeding mechanism releases the steel coil into a steel strip, which is then straightened by the flattening mechanism and enters the die table, and then the punch head punches the steel strip in the die table downward, thereby punching the steel strip into a clamp; wherein, when the steel strip enters the conveying section from the straightening section, the steel strip is located between the upper clamping roller and the lower active roller, and the steel strip is always pressed on the lower active roller by the upper clamping roller, and then the lower active roller drives the steel strip to move forward. When the punch head punches the die table downward, the punch head acts on the pressure rod, driving the pressure rod to rotate with the rotating shaft as the axis, so that the end of the supporting rod away from the rotating rod moves upward, and drives the upper clamping roller to move upward, so that the upper clamping roller is no longer pressed on the steel strip, and the steel strip loses the upper clamping force, and the friction between the steel strip and the lower active roller is reduced, so that the lower active roller cannot drive the steel strip forward, and the steel strip cannot continue to move forward, and the steel strip conveyed by the feeding mechanism droops between the straightening section and the conveying section, so that the steel strip is not easy to be completely deformed.

[0011] Optionally, the punching head is connected to a hammer acting on a pressure rod, and one end of the pressure rod away from the rotating shaft is located below the hammer.

[0012] By adopting the above technical solution, when the punch head punches the die table downward, the hammer moves downward along with the punch head, so that the hammer acts on the pressure rod.

[0013] Optionally, the pressure rod is rotatably connected to a rotating ring that abuts against the hammer.

[0014] By adopting the above technical solution, when the hammer moves downward, the hammer acts on the rotating ring, and transmits force to the pressure rod through the rotating ring, so that the pressure rod moves downward away from the end of the rotating shaft; the hammer acts on the rotating ring, converting sliding friction into rolling friction, thereby reducing the friction between the hammer and the rotating rod.

[0015] In addition, in the prior art, blocks are often used to abut against each other, that is, the hammer is a block, and the end of the rotating rod is another larger block. The block-shaped hammer moves downward to act on the block-shaped rotating rod. At the beginning, the block-shaped hammer may be in surface contact with the block-shaped rotating rod, but because the rotating rod will rotate around the rotating axis, the block-shaped rotating rod will swing. After the swing, the block-shaped hammer will no longer be in surface contact with the block-shaped rotating rod, but the edge of the hammer will be in surface contact with the rotating rod. In addition, the hammer will also slide on the rotating rod, which causes greater wear between the hammer and the rotating rod and greater noise.

[0016] Optionally, the rotating shaft is connected to a manual lever, and the manual lever extends obliquely toward a direction close to the supporting rod.

[0017] By adopting the above technical solution, when the punch moves upward, the supporting rod moves downward, so that the upper clamping roller acts on the steel belt. If the upper clamping roller cannot be pressed down on the steel belt due to friction or other reasons, the staff can pull the manual lever to manually reset the upper clamping roller through the manual lever; at the same time, the manual lever extends in the direction close to the supporting rod, that is, the manual lever and the supporting rod are located on the same side of the rotating shaft, and the manual lever provides gravity to the supporting rod, making it easier for the supporting rod to move downward.

[0018] Optionally, the bearing seat is vertically slidably connected to a limiting column that abuts against the manual shift rod.

[0019] By adopting the above technical solution, when the upper clamping roller acts on the steel belt, the manual lever abuts against the limiting column, and the movement of the manual lever is limited by the limiting column, thereby limiting the movement of the supporting rod, so that the supporting rod is always in contact with the upper clamping roller, making it convenient for the supporting rod to lift the upper clamping roller.

[0020] Optionally, the bearing seat is provided with a compression spring which enables the upper compression roller to always move closer to the lower active roller, one end of the compression spring abuts against the upper compression roller, and the other end abuts against the bearing seat.

[0021] By adopting the above technical solution, the two ends of the clamping spring are respectively in contact with the upper clamping roller and the bearing seat. Through the action of the clamping spring, the upper clamping roller always has a tendency to move toward the lower active roller, so that the upper clamping roller is pressed on the steel belt.

[0022] Optionally, the separator also includes a friction plate connected to the rotating shaft, the supporting rod is connected to a vertically arranged connecting rod, one end of the connecting rod away from the supporting rod is connected to the friction plate, and the friction plate is provided with an anti-slip sheet for contacting the steel belt.

[0023] By adopting the above technical solution, when the supporting rod drives the upper clamping roller to move upward, the friction plate moves upward together with the supporting rod, so that the anti-skid sheet of the friction plate abuts against the steel belt. The friction force between the anti-skid sheet and the steel belt makes it difficult for the steel belt to move.

[0024] Optionally, the loading tray is provided with a clamping assembly for clamping the steel coil, the clamping assembly includes a coaxial screw rod rotatably inserted into the loading tray, a movable sleeve rotatably sleeved on the screw rod, an abutment plate for abutting the steel coil, and a connecting rod, one end of the connecting rod is rotatably connected to the movable sleeve, and the other end is rotatably connected to the abutment plate.

[0025] By adopting the above technical solution, when the feeding mechanism is used, the steel coil is put on the feeding disk, and then the screw is rotated to make the movable sleeve move along the length direction of the screw. The movable sleeve drives the abutment plate to move through the connecting rod, so that the abutment plate abuts against the inner circle of the steel coil, and the steel coil is supported by the abutment plate, so that the steel coil is stable on the feeding disk.

[0026] Optionally, the loading tray is provided with a guide groove, and the abutment plate is provided with a guide block which slides in the guide groove.

[0027] By adopting the above technical solution, when the abutment plate moves, the guide block moves in the guide groove, and the abutment plate moves smoothly through the guiding action of the guide block; and, through the abutment between the guide block and the groove wall of the guide groove, the movable sleeve is not easy to rotate with the screw.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. When the stamping mechanism is stamping the steel strip, the upper pressing roller is lifted by the separation piece, so that the steel strip is not easy to move forward, and thus the steel strip is not easy to bend;

[0030] 2. When the hammer moves downward, it acts on the rotating ring, and transmits force to the pressure rod through the rotating ring, so that the pressure rod moves downward away from the end of the rotating shaft; the hammer acts on the rotating ring, converting sliding friction into rolling friction, reducing the friction between the hammer and the rotating rod;

[0031] 3. When the support rod drives the upper pressure roller to move upward, the friction plate moves upward together with the support rod, so that the anti-skid sheet of the friction plate abuts against the steel belt. The friction between the anti-skid sheet and the steel belt makes it difficult for the steel belt to move. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following is combined with Figure 1-13 This application is described in further detail.

[0047] The embodiment of the present application discloses a stamping device, wherein the clamp is stamped and formed by a steel strip 5 , and the steel strip 5 is formed by releasing and straightening a steel coil 4 .

[0048] Reference Figure 1 The clamp stamping line includes a feeding mechanism 1, a leveling mechanism 2 and a stamping mechanism 3 which are arranged in sequence. The feeding mechanism 1 releases the steel coil 4 into a steel strip 5. The steel strip 5 is leveled by the leveling mechanism 2 and then enters the stamping mechanism 3 for stamping.

[0049] See also Figure 2 and Figure 3 Specifically, the loading mechanism 1 includes a loading rack 11 and a loading tray 12. The loading tray 12 is rotatably connected to the loading rack 11 so that the loading tray 12 rotates on the loading rack 11; the steel coil 4 is connected to the loading tray 12. When the loading tray 12 rotates, it can drive the steel coil 4 to rotate, and the rotated steel coil 4 releases the steel belt 5.

[0050] See also Figure 4 and Figure 5 In order to stabilize the steel coil 4 on the loading tray 12, the loading tray 12 is provided with a clamping assembly 13, and the steel coil 4 is fixed on the loading tray 12 by the clamping assembly 13. The clamping assembly 13 includes a screw 131, a movable sleeve 132, a connecting rod 133 and an abutment plate 134. The screw 131 is rotatably connected to the loading tray 12, and the screw 131 protrudes from the side of the loading tray 12 away from the loading frame 11; the movable sleeve 132 is sleeved on the screw 131, and the movable sleeve 132 and the screw 131 are connected by threads; the abutment plate 134 slides on the end surface of the loading tray 12 away from the loading frame 11, one end of the connecting rod 133 is rotatably connected to the outer side wall of the movable sleeve 132, and the other end is rotatably connected to the abutment plate 134, and the abutment plate 134 is connected to the movable sleeve 132 by the connecting rod 133, so that the movable sleeve 132 can drive the abutment plate 134 to move.

[0051] Among them, there are multiple abutment plates 134, and the number of abutment plates 134 is specifically set according to actual conditions. In this embodiment, there are five abutment plates 134, and the five abutment plates 134 are arranged at intervals around the movable sleeve 132; when loading, the steel coil 4 is sleeved on multiple abutment plates 134, and then the screw 131 is rotated, and the screw 131 drives the movable sleeve 132 to move along the length direction of the screw 131 and close to the loading disk 12, and the movable sleeve 132 drives the abutment plates 134 to move outward through the connecting rod 133, so that the abutment plates 134 are abutted against the inner circle of the steel coil 4, and the inner circle of the steel coil 4 is pressed tightly by multiple abutment plates 134, so that the steel coil 4 is stable on the loading disk 12.

[0052] In order to ensure that the abutment plate 134 moves stably on the loading tray 12, a plurality of guide grooves 121 are opened on the end face of the loading tray 12, and the plurality of guide grooves 121 correspond one to one to the plurality of abutment plates 134. Each abutment plate 134 is connected to a guide block 135 by a screw, and the guide block 135 slides in the guide groove 121. The guide block 135 moves in the guide groove 121, so that the abutment plate 134 moves smoothly on the loading tray 12, and the guide block 135 abuts against the groove wall of the guide groove 121, so that the movable sleeve 132 is not easy to rotate with the screw 131.

[0053] join Figure 6In order to prevent the steel coil 4 from loosening easily when releasing the steel strip 5, the abutment plate 134 is connected with a clamping piece 14, and the clamping piece 14 has a clamping groove 141 for the abutment plate 134 to enter; when in use, the clamping piece 14 is first clamped on the abutment plate 134, the abutment plate 134 enters the clamping groove 141, and the clamping piece 14 is slid toward the direction close to the loading disk 12 until the clamping piece 14 abuts against the loading disk 12, and then the steel coil 4 is put on the abutment plate 134, and finally another clamping piece 14 is installed, which slides on the abutment plate 134 and abuts against the steel coil 4. The steel coil 4 is clamped by two clamping pieces 14, so that the steel coil 4 is not easy to loosen when releasing the steel strip 5.

[0054] See also Figure 1 The flattening mechanism 2 includes a straightening section 21 and a conveying section 22, and there is a distance between the straightening section 21 and the conveying section 22; after the steel coil 4 in the loading tray 12 releases the steel strip 5, the steel strip 5 first enters the straightening section 21, and the curved steel strip 5 is straightened by the straightening section 21, and then enters the conveying section 22, and finally enters the stamping mechanism 3 for stamping.

[0055] Since the straightening section 21 and the conveying section 22 are spaced apart by a distance, the steel belt 5 will have an arc-shaped droop between the straightening section and the conveying section 22, and the arc-shaped droop will reserve and buffer the conveying section 22. For example, after the steel coils 4 in the loading tray 12 are released, the steel belt 5 in the arc-shaped drooping section can still enter the conveying section 22, and the stamping mechanism 3 can continue to work, giving the staff a buffer time, during which the staff can perform the operation of closing the stamping mechanism 3 or reloading the next steel coil 4.

[0056] See also Figure 7 The straightening section 21 includes a stand 211 and two straightening roller groups 212. The two straightening roller groups 212 are mounted on the stand 211. The steel strip 5 released from the steel coil 4 is straightened by the straightening roller groups 212. Each straightening roller group 212 includes an upper adjusting roller 213 and a lower roller 214. The upper adjusting roller 213 and the lower roller 214 are arranged opposite to each other. The lower roller 214 is connected to a motor. The steel strip 5 is passed between the upper adjusting roller 213 and the lower roller 214. The upper adjusting roller 213 and the lower roller 214 are both in contact with the steel strip 5. The motor drives the lower roller 214 to rotate, thereby driving the steel strip 5 to move between the upper adjusting roller 213 and the lower roller 214.

[0057] See also Figure 8The conveying section 22 includes a bearing seat 221, a lower active roller 222 and an upper pressing roller 223. The lower active roller 222 is rotatably connected to the bearing seat 221, and the upper pressing roller 223 is rotatably and slidingly connected to the bearing seat 221. The upper pressing roller 223 can slide vertically on the bearing seat 221; the lower active roller 222 and the upper pressing roller 223 are arranged opposite to each other; the lower active roller 222 is connected to a motor, and the steel belt 5 is passed through the lower active roller 222 and the upper pressing roller 223, and the lower active roller 222 and the upper pressing roller 223 are both in contact with the steel belt 5, and the lower active roller 222 is driven to rotate by the motor, thereby driving the steel belt 5 to move between the lower active roller 222 and the upper pressing roller 223.

[0058] See also Fig. 9 The stamping mechanism 3 includes a die table 31 and a punching head 32. The die table 31 is equipped with a die, and the punching head 32 is located above the die table 31. When in use, the steel strip 5 comes out of the conveying section 22 and enters the die of the die table 31, and then the punching head 32 punches downward to punch the steel strip 5 into a clamp shape, and finally the die table 31 pushes out the stamped clamp.

[0059] See also Fig.10 and Fig.11 There is a period of time between the steel strip 5 entering the mold and the mold table 31 pushing out the stamped clamp. If no treatment is done, the conveying section 22 will continue to convey the steel strip 5 into the mold, but the steel strip 5 cannot move in the mold, making it easy for the steel strip 5 between the conveying section 22 and the mold table 31 to bend.

[0060] To solve this problem, the conveying section 22 is provided with a separator 23 on the supporting seat 221. The separator 23 includes a rotating shaft 231, a supporting rod 232 and a pressure rod 233. The rotating shaft 231 is rotatably penetrated on the supporting seat 221. One end of the supporting rod 232 is fixedly connected to the rotating shaft 231, and the other end is located below the upper clamping roller 223 and abuts against the upper clamping roller 223; the pressure rod 233 is fixedly connected to the rotating shaft 231, and the pressure rod 233 is located on the side of the rotating shaft 231 away from the supporting rod 232, and the pressure rod 233 is inclined upward and extends out of the supporting seat 221.

[0061] See also Fig.12 and Fig.13The punching head 32 is fixedly connected with a vertically arranged hammer 33, the lower end of which is conical, and the hammer 33 is located above the end of the pressure rod 233 away from the rotating shaft 231; when the punching head 32 moves downward and punches the steel strip 5, the hammer 33 acts on the pressure rod 233, the pressure rod 233 moves downward and drives the rotating shaft 231 to rotate, and the rotating rotating shaft 231 drives the supporting rod 232 to rotate around the rotating shaft 231 as the axis, so that the supporting rod 232 is away from the end of the rotating shaft 231 The upper pressing roller 223 is moved upward, thereby driving the upper pressing roller 223 to move upward, and the upper pressing roller 223 is no longer pressed on the steel strip 5, the friction between the steel strip 5 and the lower active roller 222 becomes smaller, and the lower active roller 222 is not easy to drive the steel strip 5 to move forward; when the punching head 32 has punched the steel strip 5, the hammer 33 no longer acts on the pressure rod 233, the pressure rod 233 and the supporting rod 232 return to their initial positions, and the upper pressing roller 223 is also pressed on the steel strip 5 again, and at this time, the upper pressing roller 222 drives the steel strip 5 to move forward again.

[0062] It is worth noting that a rotating ring 234 is provided at the end of the pressure rod 233 away from the rotating shaft 231. When the punch head 32 moves downward, the hammer 33 acts on the rotating ring 234, the rotating ring 234 rotates, and the conical surface at the end of the hammer 33 acts on the rotating ring 234, thereby pressing the pressure rod 233 downward.

[0063] See also Fig.10 and Fig.11 The separation member 23 also includes a friction plate 235, the upper surface of which is connected with an anti-skid sheet by glue, and the anti-skid sheet is made of rubber material; a vertically arranged connecting rod 236 is fixedly connected to the lower side of the supporting rod 232, and one end of the connecting rod 236 away from the supporting rod 232 is fixedly connected to the friction plate 235, and the friction plate 235 is separated from the supporting rod 232 by a distance through the connecting rod 236. Under normal conditions, the friction plate 235 is located below the steel belt 5 and does not abut against the steel belt 5. When the supporting rod 232 moves upward and drives the upper pressing roller 223 to move upward, it moves upward together, and the anti-skid sheet abuts against the steel belt 5. The friction plate moves the steel belt 5 upward so that the steel belt 5 does not contact the lower active roller 222. At the same time, the anti-skid sheet provides friction to the steel belt 5, so that the friction plate 235 is not easy to move the steel belt 5.

[0064] In addition, the rotating shaft 231 is fixedly connected with a manual lever 237, which is located outside the bearing seat 221 and extends obliquely toward the direction close to the supporting rod 232. When the punch 33 moves from bottom to top along with the punch head 32, the supporting rod 232 also moves downward, so that the upper pressing roller 223 abuts against the steel strip 5. Since the manual lever 237 and the supporting rod 232 are located on the same side of the rotating shaft 231, the manual lever 237 provides gravity to the supporting rod 232 during this process, so that the supporting rod 232 moves downward more easily. Moreover, the manual lever 237 is located outside the bearing seat 221. When the supporting rod 232 cannot be automatically reset, the staff can manually reset the supporting rod 232 by shifting the manual lever 237, so that the steel strip 5 can smoothly enter the mold.

[0065] See also Fig.12 and Fig.13 A limiting column 238 is provided on the outer wall of the bearing seat 221, and the limiting column 238 is located below the manual lever 237. When the upper clamping roller 223 abuts against the steel belt 5, the manual lever 237 abuts against the limiting column 238. The position of the manual lever 237 is limited by the limiting column 238, and the rotation angle of the rotating shaft 231 is limited, so that the supporting rod 232 is always in contact with the upper clamping roller 223.

[0066] In addition, the bearing seat 221 is provided with a vertically arranged sliding groove 24 , the limiting column 238 is connected to the bearing seat 221 by screws and the limiting column 238 is located in the sliding groove 24 , and when the screws are unscrewed, the limiting column 238 can slide vertically in the sliding groove 24 .

[0067] In order to ensure that the upper clamping roller 223 can always contact the steel belt 5, the bearing seat 221 is provided with a clamping spring 25, which is located above the upper clamping roller 223, one end of which contacts the upper clamping roller 223, and the other end contacts the bearing seat 221. The upper clamping roller 223 always has a tendency to move toward the lower active roller 222 through the action of the clamping spring 25. At the same time, the steel belt 5 used in different specifications of clamps has different thicknesses. The interval between the upper clamping roller 223 and the lower active roller 222 can be adjusted through the clamping spring 25. The limiting column 238 can move vertically on the bearing seat 221 and can also adapt to different steel belts 5, so that the supporting rod 232 always contacts the upper clamping roller 223.

[0068] The implementation principle of a stamping device in an embodiment of the present application is: when the stamping device is working, the steel coil 4 is first installed on the feeding mechanism 1, and the steel strip 5 is released from the steel coil 4 through the feeding mechanism 1. The steel strip 5 enters the stamping mechanism 3 after being straightened by the flattening mechanism 2, and is stamped into shape by the stamping mechanism 3.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
