Description

Technical Field

[0001] The invention relates to the technical field of hot stamping forming, and in particular to a material blocking device. Background Art

[0002] When the structural reinforcement parts of the automobile body in white are produced, the raw materials are thin steel sheets, which are produced using a hot stamping process. After the sheet is heated to the process temperature through a roller hearth furnace, the high-temperature sheet is quickly ejected from the furnace, hits the baffle plate to stop, and is quickly positioned. The sheet is then taken away by the robot and put into the mold for stamping. In order to reduce the heat loss of the high-temperature sheet in this process, the process of ejection, baffle plate, positioning, feeding, and stamping of the parts needs to be completed quickly.

[0003] Due to the different number and arrangement of sheets in different product molds, the number and position of the baffle plates need to be changed and adjusted. The weight of each sheet varies from 5 to 30 kg, and the speed of the out-of-furnace is 2 to 3 m / s. During continuous production, the baffle plates need to withstand 3,000 to 4,000 impacts per day.

[0004] The current baffles are generally divided into special baffles and universal baffles. Special baffles can only be used for one product and must be replaced when the production object is changed. This not only increases the workload and reduces work efficiency, but also requires the factory to reserve a large number of baffles to cope with different production objects. Universal baffles extend multiple baffles to different positions to meet the needs of different product production. However, the existing universal baffles have a simple structure and the movable structure has weak impact resistance, making them more easily damaged than special baffles. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problem that the adjustment mechanism of the general material baffle plate in the prior art has weak impact resistance and is easily damaged, the present invention provides a material baffle device that can not only be quickly adjusted for different products, but also has strong impact resistance and is not easily damaged.

[0020] It should be noted that the material blocking equipment described in the present invention is used for but not limited to blocking products produced by hot stamping. For the convenience of explanation, in the present invention, only the material blocking equipment blocking products produced by hot stamping is used as an example for explanation. The principle of the material blocking equipment blocking products produced by other types of equipment is essentially the same as the principle of blocking products produced by hot stamping, which will not be elaborated here.

[0021] See also Figure 1 , Figure 1 This is a structural schematic diagram of a material blocking device in an embodiment of the present invention. The material blocking device includes a frame 1, a material stopper 2, and a transverse drive 3. The material blocking device is arranged at the end of the discharge conveyor roller 4 and is used to block the workpiece on the discharge conveyor roller 4.

[0022] The frame 1 is arranged at the end of the discharge conveyor roller 4 along the width direction of the discharge conveyor roller 4, and a track 11 is formed on the upper surface of the frame 1. A plurality of stoppers 2 are slidably arranged on the track 11 to block the workpiece to stop the workpiece from moving. The transverse drive 3 is respectively connected to each stopper 2 to drive the stopper 2 to slide on the track 11, thereby adjusting the lateral position of the stopper 2.

[0023] See also Figure 2 , Figure 2 2 is a schematic diagram of the internal structure of the material stopper 2. It is easy to understand that the material stopper 2 also has an upper cover structure, but in order to clearly show the internal structure of the material stopper 2, the upper cover structure is hidden.

[0024] The material stopper 2 includes a material stopper 21, a material stopper driving device 22, a material stopper fixing device 23 and a transverse fixing device 24. The material stopper driving device 22 is connected to the material stopper 21 to drive the material stopper 21 to move along the transmission direction of the discharge conveyor roller 4, so as to adjust the position of the material stopper 21 to adapt to different workpieces. The material stopper fixing device 23 is detachably connected to the material stopper 21 to fix the material stopper 21 to resist the impact load generated when the workpiece hits. The transverse fixing device 24 is detachably connected to the track 11 to fix the material stopper 2 on the track 11.

[0025] See also Figure 3 , Figure 3 yes Figure 1 Front view of the frame 1. In some embodiments, the frame 1 includes a crossbeam 12, a guide rail 13, two lifting cylinders 14 and two articulated seats 15. A plurality of tracks 11 are formed on the upper surface of the crossbeam 12 along its length. The guide rail 13 is fixedly arranged on the lower surface of one end of the crossbeam 12 along the length of the crossbeam 12. The two lifting cylinders 14 are respectively arranged below the two ends of the crossbeam 12 for lifting the crossbeam 12. The driving ends of the two lifting cylinders 14 are respectively articulated with the two articulated seats 15, one of which is fixedly connected to the crossbeam 12, and the other articulated seat 15 is slidably connected to the guide rail 13.

[0026] When the two lifting cylinders 14 lift the cross beam 12, there will be a synchronization problem, that is, due to the difference in speed and position of the piston, the ejection height will be inconsistent, and the distance between the ends of the two piston rods will increase. At this time, if a fixed connection is used, the piston of the lifting cylinder 14 will be pulled toward the middle by the cross beam 12, and the two cylinder shafts will be stuck or damaged due to unreasonable radial force.

[0027] Since the material blocking device does not require synchronization of ejection height, the present application adopts a movable hinge solution. When the ejection heights of the two lifting cylinders 14 are not synchronized, the crossbeam 12 rotates around the fixedly connected hinge seat 15 (i.e. Figure 3The rotating shaft of the hinged seat 15 on the left side rotates, and the hinged seat 15 on the right side rotates and slides along the guide rail 13 to compensate for the lateral spacing caused by the asynchronous ejection of the two lifting cylinders 14. The cylinder shaft will not be subjected to axial tension, avoiding the problem of the lifting cylinder 14 being stuck or damaged.

[0028] See also Figure 4 , Figure 4 yes Figure 2 Exploded view of the material blocking member 21. In some embodiments, the material blocking member 21 adopts a detachable structure to facilitate disassembly and replacement. The material blocking member 21 includes a cross bar 211, a longitudinal bar 212 and a transmission rod 213. The two ends of multiple cross bars 211 and multiple longitudinal bars 212 are detachably connected to form a rectangular frame structure. As two cross bars 211 and two longitudinal bars 212 are used in the present embodiment, more cross bars 211 and longitudinal bars 212 can also be used in other embodiments to enhance the structural strength, but at the same time, the complexity of the overall structure will also be increased. Those skilled in the art can flexibly choose according to actual needs. The transmission rod 213 is arranged in parallel with the longitudinal bar 212 and is connected to the cross bar 211. The longitudinal bar 212 is along the transmission direction of the discharge conveyor roller 4, and one of the cross bars 211 faces the discharge conveyor roller 4 to block the workpiece. The material blocking drive device 22 is connected to the transmission rod 213 to drive the material blocking member 21 to move.

[0029] See also Figure 5 , Figure 5 yes Figure 2 1 is an enlarged view of the material stopper 2. In some embodiments, the material stopper 2 also includes a slide 25, a pulley assembly 26, a long linear bearing 27 and a short linear bearing 28. The slide 25 is the bottom plate of the material stopper 2, which is used to carry various components. A plurality of pulley assemblies 26 are fixedly connected to the slide 25 and are arranged on the plane where the track 11 is located, that is, on the upper surface of the crossbeam 12. Through the pulley assembly 26, the material stopper 2 can slide laterally on the crossbeam 12. A plurality of long linear bearings 27 and a plurality of short linear bearings 28 are coaxially arranged one by one and are fixedly arranged on the slide 25, wherein the short linear bearing 28 is close to the discharge conveying roller 4. Each longitudinal rod 212 is plugged in with a group of long linear bearings 27 and short linear bearings 28, and the long linear bearings 27 and short linear bearings 28 are used in conjunction with each other to obtain better structural strength in the horizontal and vertical directions when the material stopper 21 moves back and forth.

[0030] See also Figure 6 , Figure 6 yes Figure 5 A schematic structural diagram of the middle material stopper driving device 22 , in which some irrelevant structures are hidden in the figure to more clearly show the structure of the material stopper driving device 22 .

[0031] In some embodiments, the transmission rod 213 adopts a screw rod, and the screw rod 213 is fixedly connected to the cross bar 211. The material blocking drive device 22 includes a telescopic drive motor 221, a first bevel gear 222, a second bevel gear 223, a bearing bushing 224, a screw nut 225, a first bearing seat 226, a second bearing seat 227 and a sleeve 228. The telescopic drive motor 221 is fixedly arranged on the slide 25, and the transmission shaft of the telescopic drive motor 221 is coaxially fixedly connected with the first bevel gear 222 to drive the first bevel gear 222 to rotate. The second bevel gear 223 is sleeved on the ball screw and meshed with the first bevel gear 223. The second bevel gear 223 is fixedly connected to the screw nut 225 through the bearing bushing 224, and the bearing bushing 224 and the screw nut 225 are both sleeved on the screw, and the screw nut 225 is meshed with the screw. The first bearing seat 226 is fixed on the slide 25 and fixedly sleeved on the bearing bushing 224, which limits the axial movement and radial swing of the bearing bushing 224. The second bearing seat 227 is also fixed on the slide 25 and sleeved on the screw rod, and the shaft sleeve 228 is sleeved on the screw rod, and the two ends of the shaft sleeve 228 abut against the second bearing seat 227 and the second bevel gear 223 respectively.

[0032] The telescopic driving motor 221 drives the first bevel gear 222 to rotate, and the first bevel gear 222 transmits the rotation to the second bevel gear 223, and the second bevel gear 223 drives the bearing bushing 224 and the screw nut 225 to rotate. The first bearing seat 226 and the second bearing seat 227 limit the axial movement of the second bevel gear 223, the bearing bushing 224, and the screw nut 225 connected thereto. The screw rod 213 meshing with the screw nut 225, i.e., the transmission rod 213, will move axially under the drive of the screw nut 225, thereby adjusting the position of the cross bar 211 used for blocking the material.

[0033] In a preferred embodiment, the second bevel gear 223 is located on the side of the first bevel gear 222 away from the discharge conveyor roller 4, that is, away from the impact side. When the workpiece collides with the cross bar 211, the impact force is transmitted to the second bevel gear 223 through the transmission rod 213, pushing the second bevel gear 223 away from the first bevel gear 222. In this way, the impact force will not be transmitted to the first bevel gear 222, thereby protecting the telescopic drive motor 221.

[0034] See also Figure 7 , Figure 7 yes Figure 5 Schematic diagram of the structure of the middle stopper fixing device 23. In some embodiments, the stopper fixing device 23 is arranged in a one-to-one correspondence with the longitudinal rod 212, and is used to clamp and fix the longitudinal rod 212 after the cross bar 211 is adjusted to a desired position.

[0035] Each material stopper fixing device 23 includes a clamping cylinder 231, an upper clamping arm 232, a lower clamping arm 233, a wedge block 234, a height-equalizing bolt 235, and a clamping spring 236. The clamping cylinder 231 is fixed on the slide 25, and the lower clamping arm 233 is fixedly connected to the outer shell of the clamping cylinder 231. The upper clamping arm 232 is arranged above the lower clamping arm 233, and one end of the upper clamping arm 232 is rotatably connected to the lower clamping arm 233. Figure 7 The middle is the right end rotation connection. The upper clamp arm 232 and the lower clamp arm 233 are formed with grooves for clamping the longitudinal rod 212. The lower end of the equal height bolt 235 is fixedly connected to the lower clamp arm 233. The clamping spring 236 is located above the upper clamp arm 232 and abuts against the equal height bolt 235 and the upper clamp arm 233. The clamping spring 236 generates elastic force to push the upper clamp arm 232 to rotate downward to clamp the longitudinal rod 212. In this embodiment, the upper clamp arm 232 has a through hole for the equal height bolt 235 to pass through, and a gap is formed between the through hole and the equal height bolt 235 for the upper clamp arm 232 to rotate. The lower clamp arm 233 has a threaded hole for connecting with the equal height bolt 235. The clamping spring 236 is sleeved on the equal height bolt 235 and abuts against the upper surface of the upper clamp arm 232 and the bolt head of the equal height bolt 235. In other embodiments, the height bolt 235 may be replaced by another structure as long as a suitable installation position can be provided for the clamping spring 236. The wedge block 234 is fixedly connected to the driving end of the clamping cylinder 231, and the clamping cylinder 231 can drive the wedge block 234 to be inserted between the upper clamping arm 232 and the lower clamping arm 233 to push the upper clamping arm 232 and the lower clamping arm 233 to separate, thereby loosening the longitudinal rod 212. The wedge block 234 has a notch to avoid interference and collision with the height bolt 235.

[0036] See also Figure 8 , Figure 8 yes Figure 5 Exploded view of the transverse moving fixing device 24. The material stopper 2 is fixed on the crossbeam 12 by the transverse moving fixing device 24, so that the transverse positioning of the material stopper 2 is achieved.

[0037] In some embodiments, the transverse fixing device 24 includes a fixed cylinder 241, an upper clamping plate 242, a clamping link 243 and a lower clamping plate 244. The fixed cylinder 241 is arranged above the slide 25 and fixedly connected to the upper clamping plate 242, and the driving end of the fixed cylinder 241 is downwardly abutted against the slide 25. The upper clamping plate 242 is placed on the slide 25, and the upper clamping plate 242 has a hole or a groove for the driving end of the fixed cylinder 241 to pass through and abut against the slide 25. The lower clamping plate 244 is arranged in the track 11. The clamping link 243 is fixedly connected to the upper clamping plate 242 and the lower clamping plate 244, and a through hole for the clamping link 243 to pass through is opened on the slide 25. The driving end of the fixed cylinder 241 moves downward to press against the upper surface of the slide 25. Under the push of the reaction force, the fixed cylinder 241 will move upward, thereby driving the upper clamping plate 242 and the lower clamping plate 244 to move upward as well, until the upper surface of the lower clamping plate 244 is close to the upper top surface in the track 11. The lower clamping plate 244 and the slide 25 cooperate with the clamping beam 12 to achieve the lateral fixation of the material stopper 2.

[0038] See also Fig. 9 , Fig. 9 yes Figure 5 Schematic diagram of the structure of the middle pulley assembly 26. In some embodiments, the pulley assembly 26 includes a wheel 261, a pressure plate 262, a downward pressure connecting rod 263 and a downward pressure spring 264. A stepped hole for accommodating the wheel 261 and the pressure plate 262 is formed on the upper surface of the slide 25. The lower part of the wheel 261 extends through the stepped hole to the bottom of the slide 25 for rolling on the crossbeam 12. The rotating shaft of the wheel 261 is embedded in the stepped hole and can rotate freely. The pressure plate 263 is also installed in the stepped hole and presses the rotating shaft of the wheel 261 from top to bottom. The lower end of the downward pressure connecting rod 263 slides through the pressure plate 263 and is detachably connected to the slide 25. The upper end of the downward pressure connecting rod 263 extends a circle of retaining rings in the radial direction. The downward pressure spring 264 is sleeved on the downward pressure connecting rod 263, and the lower end of the downward pressure spring 264 abuts the pressure plate, and the upper end of the downward pressure spring 264 abuts the retaining ring.

[0039] The downward pressure spring 264 is in a compressed state, applying a certain elastic force to the pressure plate 262, thereby limiting the upward movement of the wheel 261 relative to the slide 25 when the material stopper 2 moves laterally. When the transverse moving fixture 24 is working to clamp the crossbeam 12, the thrust applied by the fixed cylinder 241 is much greater than the elastic force of the downward pressure spring 264, which pushes the slide 25 downward until it contacts the crossbeam 12. The downward movement of the slide 25 is equivalent to the upward movement of the wheel 261, which pushes up the pressure plate 262 and compresses the downward pressure spring 264, which is equivalent to the wheel 261 retracting back into the material stopper 2. The pulley assembly 26 adopts this structural design to adapt to the transverse moving fixture 24.

[0040] See also Figure 10-12 , Fig.10 It is a schematic diagram of the structure of the traction block; Fig.11 It is an exploded view of the traction rope arrangement; Fig.12 3 is a schematic diagram of the structure of the drive module. In some embodiments, the transverse drive 3 includes a plurality of transverse drive devices, each of which is connected to a corresponding material stopper 2. The transverse drive device includes a traction block 31, a traction steel rope 32 and a drive module 33.

[0041] The traction block 31 is slidably connected with the track 11, and the traction block 31 is also connected to the material stopper 2 in a transmission manner. In this embodiment, the slide 25 is provided with a mounting hole for the traction block 31, and the traction block 31 extends from the track 11 and is embedded in the mounting hole. The lateral dimension of the mounting hole corresponds to or is slightly larger than the lateral dimension of the traction block 31. The traction steel rope 32 is annular, runs through the track 11 and is fixedly connected to the traction block 31. The driving module 33 is connected to the traction steel rope 32 in a transmission manner to pull the traction steel rope 32, thereby driving the material stopper 2 to move laterally through the traction block 31. The traction steel rope 32 is made of steel or other materials with a certain structural strength, and is not easy to stretch so as to be able to transmit tension.

[0042] In this embodiment, two through holes are provided on each traction block 31, through which two traction steel ropes 32 respectively pass, one of which belongs to the same lateral drive device as the traction block 31, and the two are fixedly connected. The other traction steel rope 32 belongs to another lateral drive device, is fixedly connected to the traction block 31, and has no connection with the other traction steel rope 32, which only passes through the through hole. Two traction blocks 31 can be arranged in each track 11 of this vehicle to drive the two material stoppers 2 to move horizontally. Reducing the required number of tracks 11 can reduce the width of the crossbeam 12.

[0043] In this embodiment, cover plates are provided at both ends of the cross beam 12 to limit the traction steel rope 32. A wire tube 34 is also provided, and the part of the traction steel rope 32 outside the cross beam 12 is located in the wire tube 34. The wire tube 34 also plays a role in restraining the traction steel rope 32, so that when the driving module 33 pulls the traction steel rope 32, the traction steel rope can only move along its own axial direction and cannot swing to avoid transmission failure.

[0044] In this embodiment, the driving module 33 adopts a ball screw mechanism, and the motor drives the screw to rotate, thereby driving the slider on the screw to move, and the traction steel rope 32 is fixedly connected to the slider and moves with the slider. In other embodiments, other driving mechanisms can also be used as long as they can achieve controllable reciprocating movement.

[0045] It is easy to understand that in order for the material blocking device to operate normally, the material blocking device also has necessary power supply structure and gas supply structure, so that the electrical components and gas components in the material blocking device can operate normally. These power supply structures and gas supply structures are arranged in a certain way as long as they can operate normally.

[0046] When the material blocking device is in use, the transverse drive 3 drives each material blocker 2 to move to the corresponding position on the crossbeam 12 according to the shape of the workpiece. Then the transverse fixing device 24 is locked so that the material blocker 2 cannot move transversely. Then the material blocking driving device 22 drives the material blocking member 21 to move so that each cross bar 211 used for blocking is located at the required position. Finally, the material blocking fixing device 23 clamps the longitudinal bar 212 to fix the material blocking member 21, thereby completing the debugging work of the material blocking device.

[0047] Automatic control technology can also be used to pre-establish a database in the controller, and store different positions of the crossbeam 12 corresponding to various workpieces in the database. When producing different workpieces, the operator only needs to change the corresponding workpiece type with one key, and the controller can automatically control the transverse drive 3, the material stopper drive device 22 and other devices to move the crossbar 211 to the required position.

[0048] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
