Description

Technical Field

[0001] This utility model relates to the field of shell-type workpiece processing technology, and in particular to a cutting device for shell-type workpieces. Background Technology

[0002] In the processing of shell-type workpieces, the workpiece needs to be cut after the deep drawing process to ensure that the workpiece meets the dimensional requirements of subsequent processes.

[0003] However, existing processing techniques for shell-shaped workpieces still have many shortcomings. For example, the semi-finished product after deep drawing needs to be unloaded from the forming equipment, manually transferred to the cutting station, and then clamped and positioned again on the machine tool before the workpiece is cut. Throughout the process, operators need to repeatedly adjust the fixture position to fit the workpiece contour and manually calibrate the cutting reference point. Since fixture positioning relies entirely on manual experience, it is difficult to guarantee the consistency of clamping between different batches or different operators. This easily leads to cutting path deviations due to slight deviations, resulting in a high scrap rate and seriously affecting the quality of shell-shaped workpieces. Moreover, frequent manual intervention prolongs the process connection time, making the entire process time-consuming and labor-intensive, leading to a decrease in workpiece processing efficiency.

[0004] Therefore, how to improve the processing quality and efficiency of shell-type workpieces is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0058] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0059] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] This utility model provides a cutting device for shell-type workpieces, as shown in the attached figure. Figure 1 and 2 As shown, it includes a feeding device 1, a clamping device 2, a positioning device 3, a cutting device 4, and a pushing device 5.

[0061] The feeding device 1 is used to transport the workpiece 6 to be cut to the clamping position. The feeding device 1 includes a feeding drive motor, a feeding drive wheel, a feeding driven wheel, and a feeding synchronous belt wrapped between the feeding drive wheel and the feeding driven wheel. Protective plates are fixed on the upper two opposite sides of the feeding synchronous belt to prevent material from falling and causing a threat, thus improving production safety. As a preferred embodiment, the feeding device 1 includes two sets, symmetrically arranged on two opposite sides of the fixed frame 8. The "feeding position" mentioned in this text specifically refers to the position where the feeding device 1 is aligned with the clamping device 2.

[0062] The clamping device 2 is used to clamp the workpiece 6 to be cut at the clamping position. The positioning device 3 is used to position the workpiece 6 to be cut so that it is in the cutting position. The cutting device 4 is used to cut the workpiece 6 at the cutting position. The cutting device 4 is opposite to the clamping device 2. The pushing device 5 is used to push the workpiece 6 to be cut from the clamping position to the positioning device 3 before the cutting device 4 cuts, and to push the cut workpiece out of the positioning device 3 after the cutting device 4 cuts.

[0063] During processing, the feeding device 1 first transports the workpiece 6 to be cut to the clamping position, the clamping device 2 clamps the workpiece 6 at the clamping position, and the pushing device 5 pushes the workpiece 6 from the clamping position to the positioning device 3. The positioning device 3 positions the workpiece 6 to ensure that it is in the cutting position. The cutting device 4 cuts the workpiece 6 at the cutting position. After cutting, the pushing device 5 pushes the cut workpiece out of the positioning device 3.

[0064] Throughout the entire cutting process, the actions of feeding, clamping, positioning, cutting, and unloading are carried out continuously, which reduces manual intervention to a certain extent and reduces the processing errors caused by manual intervention. The operation process is time-saving and labor-saving, thereby improving the processing quality and efficiency of shell-type workpieces.

[0065] As attached Figure 3 and 4As shown, the feeding device 5 includes a drive spindle 51, a feeding reduction gearbox 52 mounted on one end of the drive spindle 51, at least one feeding transmission mechanism 53 connected to the feeding reduction gearbox 52, and at least one crank-rocker mechanism 54 connected to all feeding transmission mechanisms 53. The drive spindle 51 is parallel to the loading device 1, and the feeding reduction gearbox 52 is a gear reducer, ensuring high transmission accuracy between the drive spindle 51 and the crank-rocker mechanism, so that the feeding pin 545 is accurately aligned with the positioning hole of the feeding device 5. As a preferred embodiment, a set of feeding transmission mechanisms 53 is symmetrically arranged on each side of the feeding reduction gearbox 52, and a set of crank-rocker mechanisms 54 is connected to the end of each set of feeding transmission mechanisms 53, enabling simultaneous pushing of two workpieces 6 to be cut, thus improving processing efficiency.

[0066] It should be noted that the main drive motor 511 is installed at the end of the drive spindle 51 that is away from the pusher reducer 52. In this way, the pusher device 5, the clamping device 2 and the cutting device share a single drive unit, which is more energy-efficient and occupies less space.

[0067] In a preferred embodiment, the feeding transmission mechanism 53 is a belt drive mechanism. The feeding transmission mechanism 53 includes a feeding drive wheel 531 connected to the end output shaft of the feeding reduction gearbox 52, a feeding driven wheel 532 connected to the crank-rocker mechanism 54, a feeding synchronous belt 533 connecting the feeding drive wheel 531 and the feeding driven wheel 532, and a feeding tension wheel 534 abutting against the feeding synchronous belt 533. The feeding tension wheel 534 ensures that the feeding synchronous belt 533 maintains a set tension, guaranteeing efficient transmission of the feeding transmission mechanism 53. The feeding tension wheel 534 is mounted on a tension fixing block 535, which is fixed to a tension support plate 536, which is fixed to a stepped support 82. Specifically, the tension fixing block 535 and the tension support plate 536 are connected by an adjusting screw. When the adjusting screw is rotated, the tension fixing block 535 drives the pusher tension wheel 534 to move along the tension support plate 536, thereby adjusting the position of the pusher tension wheel 534 and thus flexibly adjusting the tension of the pusher synchronous belt 533.

[0068] In a preferred embodiment, the crank-rocker mechanism 54 includes a pusher crank 541 coaxially connected to the pusher driven wheel 532, a pusher connecting rod 542 hinged to the pusher crank 541, a pusher slider 543 hinged to the end of the pusher connecting rod 542 away from the pusher crank 541, and a pusher slide rail 544 slidably engaged with the pusher slider 543; the pusher slider 543 is fixedly provided with a pusher pin 545. The pusher crank 541 is disc-shaped, and the pusher connecting rod 542 is offset from the centerline of the pusher crank 541. The crank-rocker mechanism 54 converts the circular motion of the pusher crank 541 into the linear motion of the pusher slider 543. Preferably, the movement trajectory of the pusher slider 543 is parallel to the centerline of the positioning shaft 322. The pusher slide rail 544 is fixed on the stepped support 82.

[0069] When the drive spindle 51 rotates, the torque of the drive spindle 51 is transmitted to the push drive wheel 531 through the push reduction gearbox 52, and then to the push driven wheel 532 through the push timing belt 533. The push driven wheel 532 drives the push crank 541 to rotate synchronously. The push crank 541 pushes the push slider 543 to move linearly along the push track through the push connecting rod 542, so that the push slider 543 drives the push pin 545 to move linearly, so that the push pin 545 inserts into or disengages from the positioning hole, and correspondingly, the workpiece is placed in or disengaged from the positioning hole.

[0070] As attached Figure 5 As shown, the clamping device 2 includes a clamping fixing plate 21, a clamping cam 22, a first gripper 23, a second gripper 24, a first shift fork 25, and a second shift fork 26; wherein, the clamping fixing plate 21 is fixedly mounted on the stepped support 82. The clamping cam 22 is fixedly mounted on the drive spindle 51, so that the clamping cam 22 rotates synchronously with the drive spindle 51. The clamping cam 22 is disc-shaped, and a cam groove 221 is provided on one side of the clamping cam 22. The first gripper 23 and the second gripper 24 are slidably mounted on the bottom of the clamping fixing plate 21. Specifically, the bottom side of the clamping plate 21 is provided with a T-shaped slide rail, and the top of the first gripper 23 and the second gripper 24 are provided with a T-shaped slide groove. The T-shaped slide rail and the T-shaped slide groove can slide together, which can guide the first gripper 23 and the second gripper 24 to move closer to each other or separate from each other in a direction perpendicular to the feeding device 1, and can also provide support for the first gripper 23 and the second gripper 24 to overcome the weight of the two grippers, so that the two grippers can slide and hang on the bottom of the clamping plate 21.

[0071] Both the first fork 25 and the second fork 26 have a V-shaped structure, meaning that a V-shaped protrusion is formed in the middle section of each. The opening sides of the V-shaped protrusions of the first fork 25 and the second fork 26 face each other, and the V-shaped protrusions of both are hinged to the clamping fixing plate 21 by means of a rotating shaft. One end of the first fork 25 is provided with a first roller and the other end is connected to the first gripper 23, and one end of the second fork 26 is provided with a second roller and the other end is connected to the second gripper 24. Both the first roller and the second roller are embedded in the cam groove 221 of the clamping cam 22.

[0072] When the drive spindle 51 rotates, the clamping cam 22 rotates synchronously with the drive spindle 51; when the first roller and the second roller separate from each other in the cam groove 221, the ends of the first fork 25 and the second fork 26 away from the clamping cam 22 move closer to each other, and the first jaw 23 and the second jaw 24 slide along the clamping fixing plate 21, and the two jaws move closer to each other to clamp the workpiece 6 to be cut; when the first roller and the second roller move closer to each other in the cam groove 221, the ends of the first fork 25 and the second fork 26 away from the clamping cam 22 separate from each other, and the first jaw 23 and the second jaw 24 slide along the clamping fixing plate 21, and the two jaws separate to release the workpiece 6 to be cut.

[0073] As attached Figure 6 As shown, both the first gripper 23 and the second gripper 24 include a gripping slide 231 that slidably engages with the bottom of the gripping fixing plate 21. A fixed gripping finger 232 is integrally provided at the end of the gripping slide 231. Specifically, the fixed gripping finger 232 is an L-shaped structure fixed to the bottom of the gripping slide 231 by an interference fit. A movable gripping finger 233 is hinged to the gripping slide 231, and a return torsion spring 234 is provided between the gripping slide 231 and the movable gripping finger 233. Specifically, the gripping slide 231 has a gripping finger groove, and a gripping finger pivot pin is provided within the gripping finger groove. The movable gripping finger 233 is located on the gripping finger pivot pin, and the return torsion spring 234 is sleeved on the gripping finger pivot pin, with its two torsion arms abutting against the gripping finger groove and the movable gripping finger 233, respectively.

[0074] When the workpiece 6 to be cut enters between the fixed clamping finger 232 and the movable clamping finger 233, the return torsion spring 234 twists, providing elastic force to the movable clamping finger 233 so that the fixed clamping finger 232 and the movable clamping finger 233 clamp the workpiece 6 to be cut. When the workpiece 6 to be cut is disengaged from the fixed clamping finger 232 and the movable clamping finger 233, the return torsion spring 234 restores its elastic deformation, assisting the movable clamping finger 233 to automatically reset, making operation more convenient.

[0075] As attached Figure 7As shown, the cutting device 4 includes a fixedly mounted cutting baffle 41 and at least one set of cutting components 42 hinged to the cutting baffle 41. All cutting components 42 are located between the drive spindle 51 and the positioning device 3. Specifically, the cutting baffle 41 is vertically fixed to the end of the fixed base plate 81 away from the feeding device 1, and each set of cutting components 42 provides support. The location of all cutting components 42 between the drive spindle 51 and the positioning device 3 enables the cutting device 4 to achieve precise cutting. Specifically, the cutting baffle 41 is symmetrically provided with two sets of cutting components 42.

[0076] In a preferred embodiment, each cutting assembly 42 includes a cutting cam 421, a lifting rod 422, a lifting spring 423, and a cutting tool 424. The cutting cam 421 is fixed to the drive spindle 51. Specifically, the drive spindle 51 is equipped with two cutting cams 421, whose outer contour curves are opposite. One end of the lifting rod 422 is hinged to the cutting baffle 41, and the other end is provided with a cutting roller, which abuts against the cutting cam 421. The cutting baffle 41 is fixed with a fixing pin, and the lifting spring 423 is connected between the lifting rod 422 and the fixing pin. The lifting spring 423 is used to lift the lifting rod 422 to prevent the lifting rod 422 from swinging downward under gravity and affecting the cutting accuracy. The lifting spring 423 can be a common cylindrical spring. The cutting tool 424 is fixed to the lifting rod 422, and the lifting rod 422 is provided with a quick-release tool holder. The cutting tool 424 is mounted on the quick-release tool holder for easy and quick replacement. The cutting tool 424 is opposite to the positioning shaft 322 of the positioning device 3, ensuring that the cutting tool 424 accurately cuts the workpiece 6 held by the positioning shaft 322.

[0077] When the drive spindle 51 rotates, the cutting cam 421 rotates synchronously with the drive spindle 51. The cutting cam 421 pushes the lifting rod 422 downward through the cutting roller to overcome the elastic force of the lifting spring 423, causing the lifting rod 422 to drive the cutting tool 424 to move vertically downward, cutting the workpiece 6 held by the positioning shaft 322. When the drive spindle 51 reverses, the pushing force between the cutting cam 421 and the cutting roller is less than the elastic force of the lifting spring 423. The lifting spring 423 restores its elastic deformation, and the lifting rod 422 drives the cutting tool 424 to move upward away from the positioning shaft 322 according to the elastic force of the lifting spring 423, completing the cutting.

[0078] As attached Figure 8As shown, the positioning device 3 includes a positioning bracket 31, at least one set of positioning rotary mechanisms 32 fixed to the positioning bracket 31, a positioning drive motor 33, and at least one set of positioning transmission mechanisms 34 connected between the positioning drive motor 33 and the positioning rotary mechanisms 32. In a preferred embodiment, the positioning bracket 31 is fixed to one end of a fixed floor. Specifically, the positioning bracket 31 has two sets of positioning rotary mechanisms 32 fixed to it, and each set of positioning rotary mechanisms 32 is connected to a corresponding set of positioning transmission mechanisms 34. The two sets of positioning transmission mechanisms 34 share a single positioning drive motor 33, resulting in greater energy efficiency, a more compact structure, and a smaller footprint.

[0079] The positioning and rotating mechanism 32 includes a rotatable rotating support 321 and a positioning shaft 322 fixed to the rotating support 321; the center of the positioning shaft 322 has a positioning hole for clamping the workpiece 6 to be cut. Before the cutting device 4 cuts, one end of the workpiece 6 to be cut is inserted into the positioning hole; after the cutting is completed, the cut workpiece passes through the positioning hole under the push of the pusher pin 545 until it is completely pushed out of the positioning hole.

[0080] The positioning transmission mechanism 34 includes a positioning drive wheel 331 connected to the output shaft of the positioning drive motor 33, a positioning driven wheel 332 coaxially fixed to the slewing support 321, and a positioning timing belt 333 connecting the positioning drive wheel 331 and the positioning driven wheel 332. It should be noted that the positioning timing belts 333 of the two sets of positioning transmission mechanisms 34 are arranged in a V-shape, which ensures that the two sets of positioning transmission mechanisms 34 can transmit a large torque while reducing the space occupied by the two sets of positioning transmission mechanisms 34, making the entire positioning device 3 more compact.

[0081] As attached Figure 9 As shown, the cutting equipment for shell-type workpieces also includes a material blocking device 7 provided on the feeding device 1. The material blocking device 7 is used to block the workpiece 6 to be cut from moving with the feeding device 1 when the workpiece 6 is conveyed to the clamping position, control the conveying amount of the feeding device 1, and avoid material accumulation that would affect the cutting accuracy.

[0082] In a preferred embodiment, the material blocking device 7 includes a material blocking support 71, a driving shaft 72, a driven shaft 73, a driving gear 74, a driven gear 75, a drive roller 76, and a material blocking block 77. The material blocking support 71 is fixed above the feeding device 1. The driving shaft 72 and the driven shaft 73 are parallel to each other and perpendicular to the feeding device 1, and are rotatably mounted on the material blocking support 71. The driving gear 74 is fixed to the driving shaft 72, and the drive roller 76 is fixed to the end of the driving shaft 72 away from the driving gear 74; that is, the driving gear 74 and the drive roller 76 are respectively fixed to both ends of the driving shaft 72. The driven gear 75 is fixed to the driven shaft 73, and the material blocking block 77 is fixed to the end of the driven shaft 73 away from the driven gear 75; that is, the driven gear 75 and the material blocking block 77 are respectively fixed to both ends of the driven shaft 73. The driving gear 74 meshes with the driven gear 75, and both gears are spur gears. Specifically, the cross-section of the stop block 77 is waist-shaped, consisting of two arc surfaces and two flat surfaces connected alternately.

[0083] When the drive roller 76 abuts against the clamping device 2, the drive roller 76 drives the drive gear 74 to rotate via the drive shaft 72. The drive gear 74 drives the stop block 77 to rotate via the driven gear 75. When the long side of the stop block 77 is perpendicular to the feeding device 1, the stop block 77 reaches the blocking position, blocking the feeding channel of the feeding device 1, and the feeding device 1 stops feeding. Conversely, when the long side of the stop block 77 is parallel to the feeding device 1, the stop block 77 reaches the letting position, the feeding device 1 releases the stop, and the feeding device 1 feeds normally.

[0084] The cutting equipment for shell-type workpieces also includes a fixed frame 8, which includes a fixed base plate 81 supported by multiple support beams. A stepped support 82 is fixedly mounted on the fixed base plate 81. The pushing device 5 and the clamping device 2 are both fixed to the stepped support 82, ensuring that the drive spindle 51 keeps the loading device 1 parallel. The support legs of the fixed frame 8 are equipped with height adjustment blocks 83, which are threadedly connected to the support legs, allowing the fixed frame 8 to adjust the length of the support legs according to the ground level. This ensures that the loading device 1 remains horizontal and prevents the workpiece 6 to be cut from accidentally rolling on the loading device 1.

[0085] The positioning device 3 is provided with a feeding trough 34 below it. The cutting equipment for shell-type workpieces also includes a discharge device 9.

At the same time, the first gripper 23 and the second gripper 24 drive the drive roller 76 to rotate. The drive roller 76 drives the drive gear 74 to rotate through the drive shaft 72. The drive gear 74 drives the blocking block 77 to rotate through the driven gear 75. The blocking block 77 blocks the feeding channel of the feeding device 1.

[0090] Step 3: The workpiece 6 to be cut enters between the fixed clamping finger 232 and the movable clamping finger 233, the reset torsion spring 234 is twisted, and the fixed clamping finger 232 and the movable clamping finger 233 clamp the workpiece 6 to be cut.

[0091] Step 4: Drive the main spindle 51 to rotate and reset the clamping cam 22. At the same time, drive the main spindle 51 to transmit the material to the push drive wheel 531 through the push reducer 52, and then to the push driven wheel 532 through the push timing belt 533. The push driven wheel 532 drives the push crank 541 to rotate synchronously. The push crank 541 pushes the push slider 543 to move linearly along the push track through the push connecting rod 542. The push pin 545 pushes the workpiece 6 to be cut, held by the first clamp 23 and the second clamp 24, into the positioning hole of the positioning shaft 322.

[0092] Step 5: The positioning drive motor 33 drives the positioning drive wheel 331 to rotate. The positioning drive wheel 331 drives the positioning driven wheel 332 to rotate through the positioning timing belt 333. The positioning driven wheel 332 drives the positioning shaft 322 to rotate through the slewing support 321. The positioning shaft 322 drives the workpiece 6 to be cut to rotate.

[0093] Step 6: The drive spindle 51 drives the cutting cam 421 to rotate synchronously. The cutting cam 421 pushes the lifting rod 422 to rotate through the cutting roller. The lifting rod 422 drives the cutting tool 424 to move down to cut the workpiece 6 held by the positioning shaft 322. At the same time, the drive spindle 51 drives the pusher crank 541 to rotate through the pusher reducer 52 and the pusher transmission mechanism 53. The pusher crank 541 pushes the pusher slider 543 to move linearly along the pusher track through the pusher connecting rod 542. The pusher pin 545 pushes the workpiece out of the positioning hole and the workpiece falls into the discharge device 9.

[0094] By repeating steps one through five, continuous cutting of the workpiece can be achieved.
