[0014] Among them, a groove is provided on the side of the second mounting seat facing away from the swing arm, and an industrial camera is installed in the groove.

[0015] After adopting the above technical solutions, the beneficial effects of the present invention are:

[0016] Since the stamping device of the present invention includes a frame, a base is installed on the frame, a slider driven by oil pressure to lift is provided above the base, an upper die holder is installed on the slider, and an upper stamping die is installed on the upper die holder. The base includes a rotating seat rotatably installed on the frame, and a first power assembly for driving the rotating seat to vertically flip is installed on the frame. Four worktables are provided on the outer side of the rotating seat, and the four worktables are evenly arranged around the rotating seat. A lower die holder is installed on the worktable, and a lower stamping die is installed on the lower die holder; a clamping mechanism for fixing the sheet material on the lower stamping die is provided on the worktable; a lifting table for carrying the sheet material is provided below the rotating seat; an oiling mechanism is installed on the frame, and the oiling mechanism is arranged corresponding to the side where the rotating seat rises; a discharging mechanism is correspondingly installed on the side where the rotating seat descends. The four worktables all perform continuous operations. When the worktable is at the bottom of the rotating seat, the lifting table lifts the sheet material, and the clamping mechanism clamps the sheet material to realize the fixation of the sheet material on the worktable; as the rotating seat rotates 90°, the sheet material rotates to the left side of the rotating seat. At this time, the oiling mechanism oils the surface of the sheet material; after the oiling process is completed, the rotating seat continues to rotate 90° so that the sheet material comes to the top of the rotating body, and the slider slides down to stamp the sheet material. After the stamping is completed, the slider resets; the rotating seat continues to rotate 90° so that the sheet material rotates to the right side of the rotating seat. At this time, the discharging mechanism removes the stamped sheet material. Thus, the operation process of one worktable is completed, and the four worktables perform continuous operations, thereby greatly improving the operation efficiency. Moreover, the stamping device effectively reduces the space occupied by components, reduces the floor area of the device, and improves the space utilization rate.

[0017] Since both ends of the rotating seat are rotatably connected to the frame through rotating shafts, four card slots corresponding to the four worktables are provided at both ends of the rotating seat, a through hole is installed on the frame, a clamping block for inserting and mating with the card slot is provided in the through hole, and a first linear driving mechanism for driving the clamping block to slide in the through hole is installed on the frame. The first linear driving mechanism drives the clamping block to reciprocate in the through hole. When the card slot rotates to be aligned with the through hole, the first linear driving mechanism drives the clamping block to be inserted into the card slot, thereby further strengthening the stable locking after the rotating seat rotates 90° and ensuring the accuracy of each process operation. The linear driving mechanism is a cylinder, a hydraulic cylinder or an electric push rod.

[0018] Since the clamping mechanism includes a first permanent magnet suction cup and a clamping jaw mechanism installed on the worktable, the first permanent magnet suction cup is used for adsorbing and fixing on the surface of the sheet material, and the clamping jaw mechanism includes two clamping blocks driven by a first linear driving mechanism to move towards or away from each other, and the clamping blocks are used for clamping on the opposite sides of the sheet material. Thus, the fixation between the opposite sides of the sheet material and the fixation of the sheet material along the thickness direction are realized, and the sheet material can be quickly and efficiently clamped on the worktable. The first permanent magnet suction cup is driven to lift by a first lifting mechanism to improve the accuracy and stability of the adsorption of the first permanent magnet suction cup.

[0019] Since the oiling mechanism includes a horizontal moving mechanism, a vertical moving mechanism is installed on the moving end of the horizontal moving mechanism, a first connecting block is installed on the moving end of the vertical moving mechanism, a second connecting block is fixedly connected to the bottom surface of the first connecting block in an inclined manner, and an oiling roller is rotatably installed at the end of the second connecting block. The oiling roller adhered with drawing oil is pressed against the sheet metal under the drive of the horizontal moving mechanism, and then the vertical moving mechanism drives the oiling roller to roll downward to achieve oiling. The entire oiling process is accurate and efficient.

[0020] Since a placing plate is installed on the frame, an oil storage tank is provided on the placing plate, an opening is provided at the top of the oil storage tank, and a refueling port is provided at the side of the oil storage tank. After the oiling is completed, the oiling roller enters the oil storage tank under the combined action of the horizontal moving mechanism and the vertical moving mechanism for regular adhesion and refueling.

[0021] Since the oiling roller includes a roller body, an oil-attaching layer is sleeved outside the roller body, and the ratio of the oil level height in the oil storage tank to the thickness of the oil-attaching layer is 0.2 - 0.5, which avoids the drawing oil from adhering to the roller body and causing the splashing of the drawing oil.

[0022] Since a silica gel layer is provided at the bottom of the oil storage tank, a plurality of strip-shaped protrusions are provided on the top surface of the silica gel layer, and the plurality of strip-shaped protrusions are arranged at intervals along the moving direction of the horizontal moving mechanism. After the oiling roller is pressed against the silica gel layer, the horizontal moving mechanism drives the oiling roller to roll forward. The blocking action of the strip-shaped protrusions ensures that the oiling roller can roll continuously, improving the uniformity of the oiling roller's immersion in the drawing oil; at the same time, it can also effectively clean the impurities adhered to the oiling roller.

[0023] Since the unloading mechanism includes a first mounting seat, a swing arm, a second mounting seat, and a second linear driving mechanism, the first mounting seat is fixedly installed on the frame, one end of the swing arm is hinged to the first mounting seat, a second power assembly for driving the swing arm to swing is installed on the first mounting seat, the other end of the swing arm is hinged to the middle of the second mounting seat, a second permanent magnet suction cup is provided on the side of the second mounting seat facing away from the swing arm, the fixed end of the second linear driving mechanism is hinged to the swing arm, and the moving end of the second linear driving mechanism is hinged to the side of the second mounting seat. Under the combined action of the second power assembly and the second linear driving mechanism, the swing rod swings up to a specific position, the second mounting seat rotates to the vertical position, the first permanent magnet suction cup resets, the second permanent magnet suction cup adsorbs the sheet metal, and then the clamping jaw mechanism resets, and the swing rod swings down, so that the sheet metal is separated from the workbench, thereby realizing unloading, and the unloaded sheet metal can be stacked at a specific position.

[0024] Since two roller tables are installed on the frame in parallel, and a gap for the second mounting seat to pass through is provided between the two roller tables. When the swing rod swings down below the roller table, the second mounting frame passes through this gap, and the second permanent magnet suction cup is closed, so that the sheet metal can be supported on the roller table, and the roller table conveys the sheet metal to the next working station.

[0025] Since a groove is provided on the side of the second mounting seat facing away from the swing arm, an industrial camera is installed in the groove. When discharging, during the process of the second mounting seat moving towards the sheet metal, the industrial camera takes pictures of the sheet metal and transmits the collected image information to the vision detection system or the vision acquisition system to achieve the detection or image acquisition of the sheet metal.

[0026] In summary, the present invention solves the technical problems of low stamping efficiency and large space occupation of stamping equipment in the prior art. The present invention improves the operation efficiency and stamping quality, effectively reduces the space occupation of components, reduces the floor area of the device, and improves the space utilization rate. Moreover, the present invention also has the functions of efficient oiling, rapid blanking, and vision detection. Brief Description of the Drawings

Detailed Description of the Invention

[0031] The present invention will be further described below with reference to the drawings.

[0032] All directions involved in this specification are based on the directions when a stamping device of the present invention is working properly, without limiting its storage and transportation directions, only representing relative positional relationships, not absolute positional relationships.

[0033] As Figure 1 、 Figure 2 and Figure 3As shown together, the stamping device includes a frame 1, on which a base is installed. Above the base, there is a slider 2 driven by oil pressure to lift and lower. On the slider 2, an upper die holder 20 is installed, and on the upper die holder 20, an upper stamping die 21 is installed. The base includes a rotating seat 3, which is rotatably installed on the frame 1 through a rotating shaft, and the rotating shaft is horizontally arranged. On the frame 1, a first power component 10 is installed, and the first power component 10 drives the rotating shaft to rotate clockwise, thereby driving the rotating seat 3 to rotate synchronously in the vertical plane. Four workbenches 30 are arranged on the outside of the rotating seat 3, and the four workbenches 30 are evenly arranged around the rotating seat 3. On the workbench 30, a lower die holder 300 is installed, and on the lower die holder 300, a lower stamping die 301 is installed. In this embodiment, the rotating seat 3 is driven by the first power component 10 to rotate 90° for each station conversion. A clamping mechanism for fixing the sheet material 7 on the lower stamping die 301 is provided on the workbench 30; a lifting table 6 for carrying the sheet material 7 is provided below the rotating seat 3; an oiling mechanism 4 is installed on the frame 1, and the oiling mechanism 4 is arranged corresponding to the side where the rotating seat 3 rises (i.e., the left side of the rotating seat 3 in the figure); a discharging mechanism 5 is correspondingly installed on the side where the rotating seat 3 descends (i.e., the right side of the rotating seat 3 in the figure). The first power component 10 is a servo motor or a stepping motor.

[0034] During use, all four workbenches 30 are in continuous operation. When the workbench 30 is at the bottom of the rotating seat 3, the lifting table 6 lifts the sheet material 7, and the clamping mechanism clamps the sheet material 7 to fix the sheet material 7 on the workbench 30; as the rotating seat 3 rotates 90°, the sheet material 7 rotates to the left side of the rotating seat 3. At this time, the oiling mechanism 4 oils the surface of the sheet material 7; after the oiling process is completed, the rotating seat 3 continues to rotate 90° so that the sheet material 7 comes to the top of the rotating body, and the slider 2 slides down to stamp the sheet material 7. After stamping is completed, the slider 2 returns to its original position; the rotating seat 3 continues to rotate 90° so that the sheet material 7 rotates to the right side of the rotating seat 3. At this time, the discharging mechanism 5 removes the stamped sheet material 7. Thus, the operation process of one workbench 30 is completed, and the four workbenches 30 operate continuously, thereby greatly improving the operation efficiency. Moreover, the stamping device effectively reduces the space occupied by components, reduces the floor area of the device, and improves the space utilization rate.

[0035] Further, there are frame plates of the frame 1 corresponding to both ends of the rotating seat 3. Four card slots 33 corresponding to the four workbenches 30 are provided at both ends of the rotating seat 3. Through holes 11 are provided on the frame plates, and clamping blocks 12 are provided in the through holes 11. A first linear driving mechanism 13 is installed on the frame 1, and the first linear driving mechanism 13 drives the clamping block 12 to slide reciprocally in the through hole 11. When the card slot 33 rotates to be directly opposite to the through hole 11, the first linear driving mechanism 13 drives the clamping block 12 to be inserted into the card slot 33, thereby further strengthening the stable locking after the rotating seat 3 rotates 90° and ensuring the accuracy of each process operation. The linear driving mechanism is a cylinder, a hydraulic cylinder or an electric push rod.

[0036] Preferably, the clamping mechanism includes a first permanent magnet chuck 31 and a jaw mechanism 32. The first permanent magnet chuck 31 and the jaw mechanism 32 are installed on the workbench 30. The first permanent magnet chuck 31 is used to adsorb and fix the plate surface of the sheet metal 7. The jaw mechanism 32 includes two clamping blocks that move towards or away from each other driven by a third linear drive mechanism. The clamping blocks are used to clamp the opposite sides of the sheet metal 7. Thus, the fixation between the opposite sides of the sheet metal 7 and the fixation of the sheet metal 7 along the thickness direction are realized, and the rapid and efficient clamping of the sheet metal 7 on the workbench 30 is achieved. The first permanent magnet chuck 31 is driven to lift by a first lifting mechanism, improving the accuracy and stability of the adsorption of the first permanent magnet chuck 31.

[0037] Preferably, the oiling mechanism 4 includes a horizontal movement mechanism 40. A connecting frame 42 is installed on the moving end of the horizontal movement mechanism 40. A vertical movement mechanism 41 is installed on the connecting frame 42. A first connecting block 43 is installed on the moving end of the vertical movement mechanism 41. A vertically arranged linear guide rail 420 is installed on the connecting frame 42. The sliding block of the linear guide rail 420 is fixedly connected to the first connecting block 43. The horizontal movement mechanism 40 drives the connecting frame 42 to move horizontally, and the vertical movement mechanism 41 drives the first connecting block 43 to move vertically. Both the horizontal movement mechanism 40 and the vertical movement mechanism 41 are cylinders or electric push rods. The bottom surface of the first connecting block 43 is inclined and fixedly connected with a second connecting block 44. The second connecting block 44 extends towards the lifting table 6. The end of the second connecting block 44 is rotatably installed with an oiling roller 45. The oiling roller 45 adhered with drawing oil is pressed against the sheet metal 7 under the drive of the horizontal movement mechanism 40, and then the vertical movement mechanism 41 drives the oiling roller 45 to roll downwards to realize oiling. The entire oiling process is accurate and efficient. The oiling time can be controlled within 10 s.

[0038] Furthermore, a placement plate 46 is installed on the frame 1. An oil storage tank 47 is provided on the placement plate 46. The oil storage tank 47 is filled with drawing oil. The top of the oil storage tank 47 is provided with an opening, and the side of the oil storage tank 47 is provided with a refueling port 472. The fuel supply system continuously refuels the oil storage tank 47. After the oiling is completed, the oiling roller 45 enters the oil storage tank 47 under the combined action of the horizontal movement mechanism 40 and the vertical movement mechanism 41 to adhere to and replenish oil regularly.

[0039] Furthermore, the oiling roller 45 includes a roller body 450. An oil-attaching layer 451 is sleeved outside the roller body 450. The oil-attaching layer 451 is preferably absorbent cotton. The ratio of the oil level height in the oil storage tank 47 to the thickness of the oil-attaching layer 451 is 0.2 - 0.5, avoiding the drawing oil from adhering to the roller body 450 and causing the splashing of the drawing oil.

[0040] Further, a silica gel layer 470 is provided at the bottom of the fuel tank 47. A plurality of strip-shaped protrusions 471 are provided on the top surface of the silica gel layer 470. The plurality of strip-shaped protrusions 471 are arranged at intervals along the movement direction of the horizontal movement mechanism 40. After the oiling roller 45 is pressed against the silica gel layer 470, the horizontal movement mechanism 40 drives the oiling roller 45 to roll forward. The blocking effect of the strip-shaped protrusions 471 ensures that the oiling roller 45 can continuously roll, improving the uniformity of the oiling roller 45 soaking in the drawing oil; at the same time, it can effectively clean the impurities adhered to the oiling roller 45.

[0041] Preferably, the unloading mechanism 5 includes a first mounting seat 50, a swing arm 51, a second mounting seat 52 and a second linear driving mechanism 510. The first mounting seat 50 is fixedly installed on the frame 1. One end of the swing arm 51 is rotatably installed on the first mounting seat 50 through a first connecting shaft.

The rotation position of the second mounting seat 52 is controlled by the second linear driving mechanism 510.

[0042] During use, under the combined action of the second power assembly and the second linear driving mechanism 510, the swing rod swings up to a specific position, the second mounting seat 52 rotates to the vertical position, the first permanent magnet suction cup 31 resets, the second permanent magnet suction cup 520 adsorbs the sheet material 7, and then the jaw mechanism 32 resets. The swing rod swings down, so that the sheet material 7 is separated from the workbench 30, thereby realizing unloading. The unloaded sheet material 7 can be stacked at a specific position. In this embodiment, the second permanent magnet suction cup 520 is driven by a second lifting mechanism to lift, improving the accuracy and stability of the adsorption of the second permanent magnet suction cup 520.

[0043] Further, two roller tables 53 are installed on the frame 1 in parallel. A gap for the second mounting seat 52 to pass through is provided between the two roller tables 53. When the swing rod swings down below the roller tables 53, the second mounting frame passes through this gap, and the second permanent magnet suction cup 520 is closed, so that the sheet material 7 can rest on the roller tables 53, and the roller tables 53 convey the sheet material 7 to the next working station.

[0044] Further, a groove 521 is provided on the side of the second mounting seat 52 facing away from the swing arm 51. An industrial camera 522 is installed in the groove 521.
