[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] like Figure 1 As shown, a preferred embodiment of this utility model proposes an automatic loading and unloading stamping parts production line, which is used to produce stamping parts and can realize automatic loading and unloading.

[0033] Specifically, the production line mainly includes a heating furnace 2, stamping machines 3, a blanking robot 4, and a loading device 1. The heating furnace 2 is a mesh belt tunnel furnace with a conveyor belt 21 that passes through the heating zone inside the mesh belt tunnel furnace to transport workpieces 7 into the furnace for heating, and then conveys the heated workpieces 7 out. The loading device 1 is located near the feed end of the conveyor belt 21, and the blanking robot 4 is located near the discharge end of the conveyor belt 21. There are two stamping machines 3, located on either side of the blanking robot 4. The blanking robot 4 sequentially places the heated workpieces 7 into the two stamping machines 3 for stamping processing.

[0034] like Figure 2 As shown, the loading device 1 mainly consists of a lower cabinet 11, a positioning plate 12, a hopper 13, a pushing mechanism 14, and a transfer mechanism 15. The positioning plate 12 is installed in the middle area of ​​the top of the lower cabinet 11. There are two hoppers 13, located near the two ends of the positioning plate 12. There are also two pushing mechanisms 14, corresponding one-to-one with the two hoppers 13, used to push the stacked workpieces 7 in the hoppers 13 onto the positioning plate 12 so that the transfer mechanism 15 can grasp them.

[0035] refer to Figure 3 In this embodiment, four positioning slots 121 are provided on the positioning plate 12, with two positioning slots 121 forming a group, and there are two groups in total, corresponding to the two material bins 13 respectively. There are clearance slots 122 on both sides of the positioning slots 121 on the positioning plate 12 to facilitate the transfer mechanism 15 to grasp the workpiece 7.

[0036] refer to Figure 4The hopper 13 mainly consists of a carrier plate 131 and two limiting plates 132. The carrier plate 131 is hollow in the middle, and there is a limiting groove on each side of the upper part of the carrier plate 131, namely the first limiting groove 1311, which is used to limit the workpiece 7 as a whole. The two limiting plates 132 are vertically fixed at both ends of the carrier plate 131, and there are two limiting grooves on the opposite sides of the two limiting plates 132, namely the second limiting groove 1321, which is used to limit the ends of the workpiece 7. That is to say, one hopper 13 can store two sets of stacked workpieces 7.

[0037] The two ends of the first limiting groove 1311 are through, and the first limiting groove 1311 on the carrier plate 131 of each hopper 13 is connected to the corresponding positioning groove 121 on the positioning plate 12, so that the workpiece 7 can be pushed onto the positioning plate 12. The upper and lower ends of the second limiting groove 1321 are also through, which facilitates the stacking of workpieces 7 into the hopper 13, and at the same time facilitates the workpieces 7 falling into the first limiting groove 1311.

[0038] like Figure 4 As shown, to position the hopper 13, a clamping mechanism 16 is provided on each side of the hopper 13, and the two clamping mechanisms 16 are centrally symmetrically distributed with respect to the hopper 13. Each clamping mechanism 16 consists of a pressing cylinder 161 and a clamping element 162. The pressing cylinder 161 is vertically fixed on a cylinder mounting plate 163, which is mounted on the lower cabinet 11. The clamping element 162 is rotatably connected to the output end of the pressing cylinder 161.

[0039] After the hopper 13 is placed on the lower cabinet 11, manually rotate the clamping part 162 so that the clamping part 162 rotates above the carrier plate 131. Then, the pressing cylinder 161 controls the clamping part 162 to move down and press the carrier plate 131, thus pressing and positioning the hopper 13.

[0040] like Figure 5 As shown, the pushing mechanism 14 is located on the side of the hopper 13 away from the positioning plate 12. The pushing mechanism 14 is mainly composed of a pushing cylinder 142, a slide 143, a push rod 144, a cylinder fixing frame 141, etc. The cylinder fixing frame 141 is fixedly installed on the lower cabinet 11, the pushing cylinder 142 is horizontally fixed on one side of the cylinder fixing frame 141, the slide 143 is slidably connected to the slide rail fixed on the lower cabinet 11, and there are two push rods 144, both of which are horizontally fixed on the slide 143. The two push rods 144 correspond to the two first limiting grooves 1311 on the carrier plate 131, and the moving direction of the push rods 144 is consistent with the extending direction of the first limiting grooves 1311, so that the push rods 144 can be inserted into the first limiting grooves 1311.

[0041] A stop is provided at each end of the slide rail to prevent the slide block 143 from sliding off the slide rail.

[0042] During feeding, the slide block 143 is moved by the push cylinder 142, and the two push rods 144 are inserted into the material bin 13, that is, into the first limiting groove 1311, to push the workpiece 7 located at the bottom of the bin out of the material bin 13 and push it into the positioning groove 121 on the positioning plate 12. Then, the transfer mechanism 15 picks up the workpiece 7 and transfers it to the conveyor belt 21 of the heating furnace 2.

[0043] like Figure 6 As shown, the transplanting mechanism 15 mainly consists of a support frame 151, a transverse module 152, and a gripping component 153. The support frame 151 is fixedly installed on the lower cabinet 11 and horizontally fixed on the support frame 151. The gripping component 153 is installed on the transverse module 152. The transverse module 152 adopts a conventional motor-screw combination. The motor controls the screw to rotate, thereby driving the gripping component 153 to move. The gripping component 153 is controlled to move back and forth between the position plate 12 and the feed end of the conveyor belt 21.

[0044] refer to Figure 7 The gripping component 153 mainly consists of a lifting cylinder 1531, a fixing frame 1532, a sliding plate cylinder 1533, a positioning block 1534, and a clamping block 1535. The fixing frame 1532 is connected to the output end of the lifting cylinder 1531. Two sliding plate cylinders 1533 are provided, both horizontally fixed to the bottom of the fixing frame 1532. A positioning block 1534 is provided on each of the left and right sides of each sliding plate cylinder 1533, and each positioning block 1534 has a groove at its bottom. The clamping block 1535 is connected to the output end of the sliding plate cylinder 1533.

[0045] When the lifting cylinder 1531 controls the downward movement, the workpiece 7 will be embedded in the grooves at the bottom of the two positioning blocks 1534. Then, the sliding plate cylinder 1533 controls the clamping block 1535 to move. The clamping block 1535 will press against the middle area on one side of the workpiece 7 and cooperate with the positioning block 1534 to clamp the workpiece 7.

[0046] A transfer mechanism 15 can simultaneously grasp two workpieces 7. Two hoppers 13 feed materials alternately to ensure uninterrupted material supply.

[0047] When the workpiece 7 is conveyed into the heating furnace 2 by the conveyor belt 21, the workpiece 7 is heated at high temperature and then conveyed out by the conveyor belt 21.

[0048] like Figure 8 As shown, a material blocking mechanism 5 and a lifting mechanism 6 are provided at the discharge end of the conveyor belt 21. The material blocking mechanism 5 is used to prevent the workpiece 7 from flowing out of the conveyor belt 21, and the lifting mechanism 6 is used to grab the workpiece 7 and lift it to a certain height. Both the material blocking mechanism 5 and the lifting mechanism 6 are installed on the truss 8 at the outlet of the heating furnace 2.

[0049] refer to Figure 9 The material blocking mechanism 5 mainly consists of a blocking component 51, multiple adjusting rods 52, and multiple locking components 53. The adjusting rods 52 are arranged horizontally, vertically, and longitudinally, and are connected to each other by locking components 53. The adjusting rods 52 and locking components 53 are interlocked, and then the screw is rotated to lock the adjusting rods 52. The two ends of the blocking component 51 are connected to the corresponding adjusting rods 52 by connecting parts. The front-back, up-down, and left-right positions of the blocking component 51 can be manually adjusted by moving the adjusting rods 52.

[0050] The blocking member 51 has a protrusion on the side near the material feeding direction to form a blocking part, which is used to hold the workpiece 7.

[0051] like Figure 10 As shown, the lifting mechanism 6 mainly consists of a lifting cylinder 61, a buffer frame 62, a double-rod cylinder 63, a connecting plate 64, a clamping plate 65, and a baffle 66. The buffer frame 62 is connected to the output end of the lifting cylinder 61, and the double-rod cylinder 63 is horizontally fixed to the bottom of the buffer frame 62. The buffer frame 62 has springs, which provide a certain degree of cushioning to prevent damage to parts during downward movement.

[0052] The double-rod cylinder 63 has an output shaft at each end. Two connecting plates 64 are provided, and are connected to the output shafts at both ends of the double-rod cylinder 63 via connecting parts. The connecting plates 64 are vertically arranged, and two clamping plates 65 are provided, which are horizontally fixed to the bottom of the two connecting plates 64 respectively.

[0053] In this embodiment, each of the two clamping plates 65 has three grooves 651 on opposite sides. When the double-rod cylinder 63 controls the two clamping plates 65 to move towards each other, the two ends of the workpiece 7 will be embedded into the corresponding grooves 651, thereby clamping the workpiece 7. That is to say, three workpieces 7 can be clamped at the same time.

[0054] The groove 651 is V-shaped to limit the movement of workpieces 7 of different widths. A baffle 66 is provided on the upper part of the clamping plate 65. The two baffles 66 have an inclined surface on opposite sides so that when the two clamping plates 65 move towards each other, the two ends of the workpiece 7 are guided into the groove 651 by the inclined surface of the baffle 66.

[0055] After the lifting mechanism 6 lifts the three workpieces 7 to the designated height, the unloading robot 4 picks up the three workpieces 7 and places them onto the stamping machine 3, where they are stamped into shape. Finally, the unloading robot 4 removes the workpieces 7. The unloading robot 4 is a conventional multi-axis robot, which has the advantages of high automation and high precision. The two stamping machines 3 work alternately to improve production efficiency.

[0056] A protective net is installed between the stamping machine tool 3 and the heating furnace 2 to provide protection during processing.

[0057] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
