DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] This solution is suitable for stamping plate-shaped metal sheets. The upper mold 4 and the lower mold 11 can be replaced according to actual production needs, and both the upper mold 4 and the lower mold 11 are fixed with bolts to facilitate their replacement.

[0038] Example 1, as Figure 1 and Figure 2 As shown, a continuous stamping equipment for small hardware parts includes a bracket 1, two symmetrically distributed bases 2 are installed on one side of the top of the bracket 1, a lower mold 11 is placed between the two bases 2, a U-shaped frame 7 is installed between the two bases 2, a gantry 3 is installed on the top of the base 2, a hydraulic cylinder 6 is installed on the top of the gantry 3, a fixed plate 5 is installed at the bottom of the piston rod of the hydraulic cylinder 6, an upper mold 4 is installed at the bottom of the fixed plate 5 with bolts, a storage shell 10 is installed on the other side of the top of the bracket 1, a flipping mechanism 8 is installed on the left and right sides of the storage shell 10, a loading mechanism 9 is installed on the front of the storage shell 10, the flipping mechanism 8 is used to flip the lower mold 11 to take out the stamped hardware, and the loading mechanism 9 is used to push the hardware raw material onto the lower mold 11 when the lower mold 11 is in a horizontal state.

[0039] The size of the above-mentioned storage shell 10 can be changed according to actual production needs, so that it can be used for processing hardware of different sizes;

[0040] During the implementation of this embodiment, firstly, a number of hardware raw material sheets are placed in the inner cavity of the storage shell 10;

[0041] For further information, see Figure 5 and Figure 6 In this embodiment, the bottom of the rear side of the storage shell 10 has a discharge chute 101 for removing the hardware raw materials, and the bottom of the front side of the storage shell 10 has a limiting groove 102;

[0042] The opening height and width of the above-mentioned discharge trough 101 and the limiting groove 102 can also be designed according to actual production requirements, as long as it is ensured that only one hardware raw material piece can be discharged from the inner cavity of the storage shell 10 at a time;

[0043] The hardware raw material sheet located on the bottom wall of the inner cavity of the storage shell 10 is at the same level as the discharge slot 101 and the limiting slot 102;

[0044] Secondly, the fixed plate 5 is moved to the middle position of the gantry 3 in the vertical direction by the hydraulic cylinder 6, the feeding mechanism 9 is at the front side of the limiting groove 102, and the hardware raw material sheet at the bottom contacts the bottom wall of the storage shell 10;

[0045] After the hydraulic cylinder 6 starts running, it drives the upper mold 4 and the fixed plate 5 to move synchronously. The fixed plate 5 drives the feeding mechanism 9 to push the hardware raw material sheet at the bottom to just above the lower mold 11. Then, under the continuous downward pressure of the fixed plate 5, the pulling effect on the feeding mechanism 9 is released, and the feeding mechanism 9 returns to its initial position. At the same time, under the action of gravity, the stacked hardware raw material sheets fall freely and are refilled. After the stamping is completed, the hydraulic cylinder 6 is opened in the reverse direction, and then the upper mold 4 is separated from the finished hardware product. As the fixed plate 5 continues to move upward, the flipping mechanism 8 is driven to run and the fixed plate 5 and the feeding mechanism 9 are reset, and the lower mold 11 is flipped over to pour out the stamped hardware product, thereby completing the entire stamping process.

[0046] Embodiment 2: Based on the embodiment 1, this embodiment optimizes the feeding mechanism 9 so that the feeding mechanism 9 can cooperate with the fixed plate 5 and the like to perform feeding during the stamping process.

[0047] Specifically, to achieve the above purpose, refer to Figure 3 、 Figure 4 、 Figure 7 and Figure 8 97 and 99 are mounted on the top of the gantry 3. The top of the two slide rails 91 is provided with a stabilizing member 92. The top of the stabilizing member 92 is provided with a loading plate 93 for pushing the hardware raw materials. The loading plate 93 is located in the inner cavity of the limiting groove 102. The front of the front and rear sides of the loading plate 93 are provided with a driving member 94. The side of the two driving members 94 close to each other is provided with a limiting plate 95. A spring 2 96 is installed between the two driving members 94 and the fixed frame 81. The surfaces of the driving member 94, the fixed pulley 1 97 and the fixed pulley 2 99 on the same side are commonly wrapped with a pull rope 2 98. The tail ends of the two pull ropes 2 98 pass through the top of the gantry 3 and the top of the fixed plate 5 and extend to the lower part and are fixed with a guide rod 90. The upper parts of the two guide rods 90 are both provided with upper limit blocks 901.

[0048] For further information, see Figure 12 In this embodiment, rubber balls 100 are fixed on the upper parts of the two guide rods 90;

[0049] The rubber ball 100 in this embodiment is a soft ball made of rubber material, which will deform when squeezed.

[0050] The implementation method in this embodiment is divided into the following steps:

[0051] 1. When the hydraulic cylinder 6 is not working, the upper mold 4 is in the vertical middle of the gantry 3, the rubber ball 100 is below the fixed plate 5, the loading plate 93 has not entered the inner cavity of the storage shell 10, the hardware raw material sheet is in contact with the bottom wall of the storage shell 10, and the loading plate 93 is located directly behind the lowest hardware raw material sheet.

[0052] 2. After the hydraulic cylinder 6 starts running, under the constraint of the two rubber balls 100, the pull rope 2 98, the driving member 94 and the loading plate 93 are dragged to move backward synchronously, and the hardware raw material sheet is pushed out through the discharge chute 101 by the loading plate 93 and moved to the top of the lower mold 11. When the limit plate 95 is in contact with the outer surface of the storage shell 10, the loading plate 93 stops moving. At this time, the guide rod 90 also stops moving downward synchronously, and the compression process of the spring 2 96 stops.

[0053] 3. When the stamping starts, the hole on the fixed plate 5 where the guide rod 90 is installed will continuously squeeze the rubber ball 100, causing the rubber ball 100 to deform and enter the hole. As the fixed plate 5 continues to move, the rubber ball 100 moves to the top of the fixed plate 5, and the constraint effect between the fixed plate 5 and the rubber ball 100 is terminated. The elastic force of the spring 2 96 is released, pushing the driving member 94 to drive the loading plate 93 to return to its initial position. The loading plate 93 leaves the inner cavity of the storage shell 10. At this time, under the action of gravity, the hardware raw material sheet automatically falls down to perform the filling operation.

[0054] 4. After the stamping is completed, under the action of the hydraulic cylinder 6, the fixed plate 5 returns to its original position and moves upward. Under the obstruction of the upper limit block 901, the guide rod 90 remains in its initial position. The hole on the fixed plate 5 squeezes the rubber ball 100 again, so that it moves through the hole to the bottom of the fixed plate 5 and prepares for the next loading.

[0055] Embodiment 3: This embodiment optimizes the blanking structure based on the embodiment. After the stamping is completed, the stamped hardware can be automatically taken out as the fixing plate 5 is reset.

[0056] Specifically, in order to achieve the above purpose, see Figure 4 、 Figure 7 、 Figure 8 and Figure 9 In this embodiment, the turning mechanism 8 includes a fixing frame 81 installed on one side of the top of the bracket 1, the storage shell 10 is fixed on the top of the fixing frame 81, and racks 83 are provided on the front and rear sides of the fixing frame 81. A spring 82 is provided between the front and rear sides of the top of the fixing frame 81 and the rack 83 on the same side, and a pull rope 84 is installed between the front sides of the tops of the two racks 83 and the bottom of the fixed plate 5.

[0057] In this embodiment, when the fixed plate 5 moves upward, the rack 83 will be dragged backward by the pull rope 84, so that it can drive the gear 87 and then drive the drive rod 86 and the lower mold 11 to flip backward synchronously, and pour out the stamped hardware. At this time, the two springs 82 are stretched.

[0058] Furthermore, in this embodiment, a driving rod 86 is provided at the top of the U-shaped frame 7. The driving rod 86 rotates at the top of the U-shaped frame 7 and is fixed to the lower mold 11. When the driving rod 86 rotates, it is used to drive the lower mold 11 to rotate. Gears 87 that mesh with the racks 83 on the same side are installed on both sides of the driving rod 86.

[0059] After the fixed plate 5 descends again, the elastic force generated by the two springs 82 is released, and the rack 83 is pulled back to its initial position in the opposite direction. With the cooperation between the rack 83 and the gear 87, the lower mold 11 returns to its initial position again, waiting for the next release of hardware raw materials.

[0060] Embodiment 4: Based on embodiment 3, this embodiment optimizes the process of removing the stamped finished part from the lower die 11 to prevent the finished part from being stuck in the inner cavity of the lower die 11.

[0061] The lower mold 11 in this case needs to be processed before implementation, including slotting and installing the structure in the slot. The specific content is as follows:

[0062] Specifically, to achieve the above purpose, refer to Figure 9 、 Figure 10 and Figure 11 In this embodiment, mounting grooves 111 are provided on both the front and rear sides of the top of the lower mold 11. Springs 112 are provided inside the two mounting grooves 111. Push plates 113 that slide in the inner cavity of the mounting grooves 111 on the same side are installed on the rear sides of the two springs 112. A detachable limit baffle 115 is installed on the rear side of the top of the lower mold 11.

[0063] Two top blocks 116 are installed on the top front side of the U-shaped frame 7;

[0064] Both top blocks 116 are on the rotation trajectory of the reclaiming block 114 , and the orientation of the top blocks 116 is also the same as the motion trajectory of the reclaiming block 114 ;

[0065] Depend on Figure 10 It can be seen that the top of the material removal block 114 has a slope, which can lift the corners of the stamped hardware during the implementation process. As the material removal block 114 continues to penetrate deeper, it will eventually completely lift the stamped hardware, and with the lower mold facing downward, the stamped hardware can fall off by itself.

[0066] The rear sides of the two push plates 113 are both equipped with a material removal block 114 for ejecting finished hardware parts;

[0067] After the stamping is completed, the rack 83 and the gear 87 cooperate with each other to drive the lower mold 11 to flip backward. During the flipping process, when the material removal block 114 contacts the top block 116, the material removal block 114 can be pushed inward by the top block 116, and the stamped product can be taken out from the inner cavity of the lower mold 11 through the inclined surface of the material removal block 114. When the material removal block 114 is separated from the top block 116, the material removal block 114 can be restored to its original position under the push of spring three 112.

[0068] The limit baffle 115 in this case is used to limit the moving distance of the hardware raw materials and improve the accuracy of loading;

[0069] During the implementation process, the bottom of the inclined surface of the material taking block 114 and the limiting baffle 115 are on the same horizontal line.

[0070] During the implementation process, after the hardware raw material sheet slides out of the inner cavity of the discharge chute 101 to the top of the lower mold 11, the rear end of the hardware raw material sheet is blocked by the limit baffle 115, and is located at the foot of the slope of the material removal block 114, ensuring that the hardware raw material sheet is in a horizontal state, improving the stamping quality, and ensuring the stamping effect.

[0071] The entire implementation process of the small hardware continuous stamping equipment is as follows:

[0072] 1. Preparation

[0073] Several hardware raw material sheets are stacked in the inner cavity of the storage shell 10 to ensure that the bottom raw material sheet is in contact with the bottom wall of the storage shell 10 and is at the same horizontal height as the discharge chute 101 and the limit groove 102; adjust the hydraulic cylinder 6 so that the fixed plate 5 is located in the middle of the gantry 3 in the vertical direction, the feeding mechanism 9 is at the front side of the limit groove 102, and the lower mold 11 is in a horizontal state.

[0074] 2. Loading process

[0075] The hydraulic cylinder 6 starts to drive the fixed plate 5 and the upper mold 4 to move downward:

[0076] The fixed plate 5 pulls the driving member 94 of the feeding mechanism 9 through the pull rope 98, driving the feeding plate 93 to move backward along the slide rail 91, pushing the hardware raw material sheet at the bottom of the storage shell 10 out of the discharge chute 101 and sending it to the top of the lower mold 11;

[0077] When the limit plate 95 is in contact with the outer surface of the storage shell 10, the loading plate 93 stops moving. At this time, the fixed plate 5 continues to move downward, and its hole squeezes the rubber ball 100 on the guide rod 90, so that the rubber ball 100 moves through the hole to the top of the fixed plate 5, releasing the tension on the pull rope 2 98;

[0078] The spring 2 96 of the feeding mechanism 9 releases its elastic force, pushing the driving member 94 and the feeding plate 93 to return to their initial positions and separate from the storage shell 10; the raw material sheets in the storage shell 10 automatically fall down to fill their positions under the action of gravity, preparing for the next feeding.

[0079] 3. Stamping process

[0080] The fixed plate 5 drives the upper mold 4 to continue to move downward, and the upper mold 4 is closed with the lower mold 11 to complete the stamping process of the hardware raw material.

[0081] 4. Material collection process

[0082] After the stamping is completed, the hydraulic cylinder 6 drives the fixed plate 5 and the upper die 4 to move upward and reset:

[0083] The upper mold 4 is separated from the finished hardware product. When the fixed plate 5 moves upward, the rack 83 of the flip mechanism 8 is pulled backward by the pull rope 1 84, and the spring 1 82 is stretched.

[0084] The rack 83 meshes with the gears 87 on both sides of the drive rod 86, driving the drive rod 86 and the lower mold 11 to flip backward;

[0085] During the flipping process, the material removal block 114 on the lower mold 11 contacts the top block 116 on the top of the U-shaped frame 7. The top block 116 pushes the push plate 113 to compress the spring 3 112. The inclined surface of the material removal block 114 ejects the stamped hardware product from the lower mold 11, and the finished product automatically falls as the lower mold 11 flips;

[0086] When the lower mold 11 is flipped to the maximum angle, the material taking block 114 is separated from the top block 116, the spring 3 112 releases its elastic force, and the push plate 113 and the material taking block 114 are reset.

[0087] 5. Reset process

[0088] The fixed plate 5 continues to move up to the initial position, the spring 1 82 of the flipping mechanism 8 releases its elastic force, pulling the rack 83 to reset forward, and the gear 87 rotates in the opposite direction, driving the driving rod 86 and the lower mold 11 to flip back to the horizontal state; at the same time, when the fixed plate 5 moves up, its hole squeezes the rubber ball 100 again, so that the rubber ball 100 moves through the hole to the bottom of the fixed plate 5, and the guide rod 90 of the feeding mechanism 9 remains in the initial position under the obstruction of the upper limit block 901, ready for the next cycle.
