Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die based on linked self-elastic material. Background Art

[0002] The rational use of stamping dies shortens the working cycle and reduces production costs, thereby shortening the production cycle and improving the competitiveness of enterprises. In addition, stamping dies have the advantages of high precision and high adaptability, and thus stamping dies are widely used in the industrial field.

[0003] When the stamping die is working, after processing the material, there will be finished parts and waste. The finished parts will fall directly onto the transport component and be transported to the next processing location, while the waste needs to be cleaned by the staff. During the processing, the waste may get stuck on the die due to burrs, which makes it inconvenient for the staff to operate.

[0004] In order to overcome the above-mentioned defects, prior art 1 (Chinese patent application number CN202110041627.1, application date 2021-01-13) is a stamping die spring device, which, under the action of a motor, rotates its screw, thereby enabling the threaded sleeve and two sets of lifting rods to move upward, and then enabling the limit plate to continue to move upward to a height that is convenient for the user to take out the mold. The setting of the two sets of baffles can, to a certain extent, prevent the mold from falling from the top surface of the limit plate during the lifting process;

[0005] During use, after the device ejects the material, it is also necessary to discharge the material from the mold so that the next operation can proceed normally. However, during use, the device in the above application still requires the staff to manually remove the workpiece after ejecting the material, which increases the workload of the staff and brings unnecessary trouble to the stamping work.

[0006] In response to the above problems, it is urgent to carry out innovative design based on the original stamping die. Utility Model Content

[0007] The purpose of the present utility model is to provide a stamping die based on linked self-elastic material, so as to solve the problem raised in the above background technology that during use, after the material is elastic, the staff still needs to manually remove the workpiece, which increases the workload of the staff and brings unnecessary trouble to the stamping work.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a stamping die based on linked self-elastic material, comprising a lower plate, the upper surface of which is fixedly connected to a hydraulic rod, the output end of which is fixedly connected to an upper plate, the upper surface of which is fixedly connected to a lower die, and the lower surface of which is fixedly connected to an upper die;

[0009] Also includes:

[0010] A fixed box, the fixed box is fixedly connected to the upper surface of the lower plate, and a push plate is slidably provided inside the fixed box, and a vertical plate is fixedly connected to the upper surface of the lower plate;

[0011] A connecting plate, the connecting plate being fixedly connected to the lower surface of the upper plate, and a working rod being slidably provided inside the connecting plate;

[0012] A connecting block, the connecting block is fixedly connected to the upper surface of the lower plate, and a connecting shaft is rotatably provided inside the connecting block;

[0013] The columns are fixedly connected to the upper surface of the lower plate, and the columns are symmetrically distributed about the center of the lower plate. The surfaces of the columns are sleeved with blanking plates, and the ends of the columns are convex.

[0014] Preferably, the lower surface of the end of the working rod is inclined, and the other end of the working rod is fixedly connected to a force-bearing plate, and the force-bearing plates are symmetrically distributed about the center of the connecting plate.

[0015] Preferably, a connecting spring having an elastic reset function is fixedly connected to the surface of the force-bearing plate, and the other side of the connecting spring is fixedly connected to the outer wall of the connecting plate.

[0016] Preferably, a force-bearing rod is fixedly connected to the surface of the push plate, and the force-bearing rod corresponds to the working rod one-to-one, and limit blocks are fixedly connected to the left and right sides of the push plate.

[0017] Preferably, a reset spring having an elastic reset function is fixedly connected to the upper surface of the limit block, and the other side of the reset spring is fixedly connected to the inner wall of the fixing box.

[0018] Preferably, a first magnet is fixedly connected to the surface of the force-bearing plate, and a second magnet corresponding to the first magnet is fixedly connected to the surface of the vertical plate, and the magnetic poles of the second magnet and the first magnet at adjacent positions are opposite.

[0019] Preferably, a traction rope is wound and fixedly connected to the surface of the connecting shaft, and the other side of the traction rope is fixedly connected to the lower surface of the upper plate, and the surface of the connecting shaft is convex.

[0020] Preferably, a torsion spring that plays an elastic reset role is fixedly connected to the surface of the connecting shaft, and the other side of the torsion spring is fixedly connected to the inner wall of the overlap block, and a cam is fixedly connected to the surface of the connecting shaft, and the blanking plate is set at an angle.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the stamping die based on the linked self-elastic material adopts a new structural design, the specific contents of which are as follows:

[0022] The stamping die based on linked self-elastic material places the material on the lower die during operation, then activates the hydraulic rod to make the upper plate drive the upper die to work, and finally completes the stamping work. The product falls directly, and the waste material stays on the lower die.

[0023] Furthermore, when the connecting plate and working rod descend, the working rod will eventually contact the stress-bearing rod. At this time, the working rod drives the stress-bearing plate to move in the direction of the stretched connecting spring. When the upper plate, connecting plate and working rod continue to descend and the working rod no longer contacts the stress-bearing rod, the working rod returns to its original position under the action of the connecting spring. After the stamping is completed, the upper plate and upper mold rise. At this time, the pusher plate rises under the action of the working rod and stress-bearing rod, and then the pusher plate pushes the waste material to the discharge plate, making it easier for the discharge plate to discharge the waste material.

[0024] Furthermore, when the push plate and the force-bearing rod are driven to rise by the working rod, the limit block will squeeze the return spring, and when the working rod continues to rise and the first magnet and the second magnet are in the same horizontal direction, the working rod moves away from the force-bearing rod under the action of the mutual magnetic force, and finally the force-bearing rod is no longer in contact with the working rod. At this time, the force-bearing rod and the push plate fall back to their original position under the action of the limit block and the return spring, making it convenient for next use;

[0025] The stamping die based on linked self-elastic material, when the upper plate is away from the lower plate, the upper plate drives the connecting shaft to rotate inside the overlap block through the traction rope. At this time, the torsion spring is stretched, that is, when the push plate pushes the material, the connecting shaft drives the cam to rotate continuously, and then the cam will intermittently push the blanking plate. At this time, the blanking plate performs reciprocating linear motion in the vertical direction under the action of the cam, its own gravity and the column, and the blanking plate is in a vibrating state, which can unload the material faster. Manual operation is no longer required for the staff, and the waste material falls directly, thereby improving work efficiency.

[0026] (3) In the stamping die based on linked self-elastic material, when the upper plate descends and the stamping process is in progress, the connecting shaft loses the tension of the traction rope. At this time, the connecting shaft rotates under the action of the torsion spring, and then the connecting shaft will reel in the traction rope for the next use. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Including lower plate 1, the upper surface of lower plate 1 is fixedly connected with hydraulic rod 3, and the output end of hydraulic rod 3 is fixedly connected with upper plate 2, and the upper surface of lower plate 1 is fixedly connected with lower mould 4, and the lower surface of upper plate 2 is fixedly connected with upper mould 5.

[0039] During operation, the material is placed on the lower die 4, and then the hydraulic rod 3 is started to make the upper plate 2 drive the upper die 5 to work, and finally the stamping work is completed. The product falls directly and the waste remains on the lower die 4.

[0040] Embodiment 2: The difference from embodiment 1 is that the waste on the upper surface of the lower mold 4 can be quickly discharged by setting the push plate 7. Figures 3-6 As shown:

[0041] A fixed box 6 is fixedly connected to the upper surface of the lower plate 1, and a pusher plate 7 is slidably provided inside the fixed box 6, and a vertical plate 13 is fixedly connected to the upper surface of the lower plate 1, and a connecting plate 9 is fixedly connected to the lower surface of the upper plate 2, and a working rod 10 is slidably provided inside the connecting plate 9;

[0042] The overlapping block 18 is fixedly connected to the upper surface of the lower plate 1, and the connecting shaft 19 is rotatably provided inside the overlapping block 18, and the column 22 is fixedly connected to the upper surface of the lower plate 1, and the columns 22 are symmetrically distributed about the center of the lower plate 1, and the surface of the column 22 is sleeved with a blanking plate 23, and the end of the column 22 is a convex shape.

[0043] The lower surface of the end of the working rod 10 is inclined, and the other end of the working rod 10 is fixedly connected to a force-bearing plate 11, and the force-bearing plate 11 is symmetrically distributed about the center of the connecting plate 9. The surface of the force-bearing plate 11 is fixedly connected to a connecting spring 15 that plays an elastic reset role, and the other side of the connecting spring 15 is fixedly connected to the outer wall of the connecting plate 9.

[0044] The surface of the push plate 7 is fixedly connected to a force-bearing rod 8, and the force-bearing rod 8 corresponds one-to-one to the working rod 10, and the left and right sides of the push plate 7 are fixedly connected to a limit block 16, and the upper surface of the limit block 16 is fixedly connected to a reset spring 17 that plays an elastic reset role, and the other side of the reset spring 17 is fixedly connected to the inner wall of the fixed box 6.

The second magnet 14 and the first magnet 12 have opposite magnetic poles at adjacent positions.

[0046] When the upper plate 2 is lowered, the connecting plate 9 and the working rod 10 are lowered synchronously, and the working rod 10 finally contacts the force rod 8, at this time, the working rod 10 drives the force plate 11 to move in the direction of stretching the connecting spring 15, when the upper plate 2, the connecting plate 9 and the working rod 10 continue to be lowered, the working rod 10 is not in contact with the force rod 8, the working rod 10 returns to the original position under the action of the connecting spring 15, and the stamping is finished, then the upper plate 2 and the upper die 5 are lifted, at this time, the working rod 10 drives the pushing plate 7 to lift through the force rod 8, and then the pushing plate 7 pushes the waste material to the discharging plate 23, so that the waste material is discharged from the discharging plate 23;

[0047] When the pushing plate 7 and the force rod 8 are lifted by the working rod 10, the limiting block 16 extrudes the reset spring 17, and when the working rod 10 continues to rise, the first magnet 12 and the second magnet 14 are in the same horizontal direction, under the action of mutual magnetic force, the working rod 10 moves away from the force rod 8, and finally the force rod 8 is not in contact with the working rod 10, at this time, the force rod 8 and the pushing plate 7 are lowered to the original position under the action of the limiting block 16 and the reset spring 17, so as to facilitate the use next time.

[0050] When the upper plate 2 moves away from the lower plate 1, the upper plate 2 drives the connecting shaft 19 to rotate in the lap block 18, at this time, the torsion spring 24 is stretched, that is, when the pushing plate 7 pushes the material, the connecting shaft 19 and the cam 20 are in a rotating state, the connecting shaft 19 drives the cam 20 to rotate all the time, and then the cam 20 intermittently pushes the discharging plate 23, at this time, the discharging plate 23 does reciprocating linear motion in the vertical direction under the action of the cam 20, its own gravity and the vertical column 22, and then the discharging plate 23 is in a vibrating state, so that the waste material can be discharged faster, and the working efficiency is improved.
