Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a sheet stamping die. Background Technology

[0002] Sheet stamping dies are key tools used to process metal or non-metal sheets into parts of specific shapes and sizes, and are widely used in manufacturing.

[0003] For example, a sheet metal stamping die disclosed in patent publication number CN222710608U, by controlling a second hydraulic telescopic rod to drive a push block to move upward, the push block moves upward via an L-shaped plate, and the L-shaped plate moves upward via a connecting plate and a support plate, causing a lifting plate to move upward, so that the lifting plate lifts the sheet metal stamped in the groove, thereby making it easy to move the stamped sheet metal out, and continuing to drive the push block to move upward to push a triangular plate, the triangular plate will drive the push plate to move to the left to push the sheet metal lifted by the lifting plate, thereby making it easy to push and remove the stamped sheet metal without manual removal, making the operation more labor-saving and reducing the labor intensity of sheet metal processing.

[0004] The above-mentioned existing equipment facilitates the ejection of sheet metal from the groove and pushes it away through a coordinated triangular plate. However, this type of equipment has the following problems when in use:

[0005] 1. Although the combination of the second hydraulic telescopic rod, the L-shaped plate, and the push block can move the lifting plate, the L-shaped plate is prone to deformation and damage after long-term use, and it is not easy to replace.

[0006] 2. When the push block contacts the triangular plate, one end of the triangular plate moves. However, after a long period of contact, the surfaces of the push block and the triangular plate are prone to wear, which increases the friction of the contact surface and reduces the service life of the device.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a sheet stamping die, including a frame 1, a stamping mechanism 2 and a die plate 4 with a groove 3. The stamping mechanism 2 is disposed on the inner top surface of the frame 1. It should be noted that the stamping mechanism 2 is driven by an existing stamping cylinder (because the stamping mechanism 2 is a common existing technology in the market, the structure of this device is not described).

[0025] An ejector block 5 is snapped into the groove 3. A lifting assembly 6 is provided at the bottom of the frame 1. The lifting assembly 6 is used to push the ejector block 5 to move up and down in the groove 3. A pusher frame 7 is slidably snapped into one side of the upper surface of the mold plate 4. The lifting assembly 6 is used to push the pusher frame 7 to move. The lifting assembly 6 includes a lifting block 601, a linkage frame 602 and a support frame 603. The linkage frame 602 and the support frame 603 are detachably connected to the lifting block 601.

[0026] Example 2: As Figure 2 and Figure 4 As shown, the lifting assembly 6 also includes a lifting motor 604, which is fixedly installed inside the bottom end of the frame 1. A lifting screw 605 is fixedly installed at the output end of the lifting motor 604. A guide rod 606 is fixedly installed on the bottom surface of the frame 1. A lifting block 601 is slidably inserted into the guide rod 606. The lifting block 601 has a screw hole that cooperates with the lifting screw 605. The linkage frame 602 and the support frame 603 are respectively inserted into the two sides of the lifting block 601. It should be noted that the lifting motor 604 is a servo motor, which is controlled by an external PLC and powered by an external power supply.

[0027] The lifting block 601 has T-shaped holes 607 distributed on it. T-shaped rods 608 are inserted into the T-shaped holes 607. The T-shaped rods 608 pass through one end of the linkage frame 602 and the support frame 603 respectively. A fastening spring 609 is installed in the T-shaped hole 607. One end of the fastening spring 609 is fixedly connected to the T-shaped rod 608. It should be noted that, through the cooperation of the T-shaped rod 608 and the fastening spring 609, when one end of the linkage frame 602 and the support frame 603 is inserted into the lifting block 601, the elastic force of the fastening spring 609 allows the T-shaped rods 608 to be inserted into the interior of the linkage frame 602 and the support frame 603, thereby fixing the support frame 603 and the linkage frame 602.

[0028] Example 3: As Figure 4As shown, the linkage frame 602 consists of a insertion frame 6021 and an insertion plate 6022. Insertion springs 6023 are symmetrically arranged inside the insertion frame 6021. The insertion plate 6022 is inserted into the insertion frame 6021, with one end of the insertion plate 6022 fixedly connected to the insertion spring 6023. Limiting rods 8 are distributed on the bottom surface of the frame 1, and a top plate 9 is sleeved on the limiting rods 8. The insertion plate 6022 is inserted into the top plate 9. T-shaped insertion holes 611 are symmetrically opened on the top plate 9. T-shaped rods 612 are inserted into the T-shaped insertion holes 611, with one end of the T-shaped rod 612 penetrating one end of the insertion plate 6022. A fixing spring 610 is fixedly installed inside the T-shaped insertion hole 611. One end is fixedly connected to the T-shaped rod 612. A top rod 10 is fixedly installed on the upper surface of the top plate 9. The upper end of the top rod 10 is fixedly connected to the ejector block 5. It should be noted that the linkage frame 602 can be telescopically adjusted to facilitate the disassembly and assembly of the linkage frame 602. When the insert plate 6022 inside the linkage frame 602 is inserted into the top plate 9, the insert plate 6022 can be fixed by the cooperation of the T-shaped rod 612 and the fixing spring 610. Thus, when the lifting block 601 is raised or lowered, the top plate 9 can be raised by the linkage frame 602, thereby raising the ejector block 5 and pushing out the stamped part in the groove 3.

[0029] Example 4: Figure 5 and Figure 6 As shown, a wedge block 11 is fixedly installed on the upper end of the support frame 603. One end of the push frame 7 has a wedge-shaped structure. The wedge-shaped surface of one end of the push frame 7 is evenly engaged with the rotating roller 12. The surface of the mold plate 4 is provided with a sliding groove 13. A sliding rod 14 is fixedly installed inside the sliding groove 13. A sliding spring 15 is sleeved on the sliding rod 14. The lower part of the push frame 7 is slidably engaged inside the sliding groove 13. The lower end of the push frame 7 is sleeved on the sliding rod 14. The sliding spring 15 and the push frame 7 are fixedly connected to each other. It should be noted that when the support frame 603 rises, the wedge block 11 will come into contact with the wedge-shaped structure at one end of the push frame 7. When the wedge block 11 comes into contact with one end of the push frame 7, the rotating roller 12 will rotate. At this time, the push frame 7 will move laterally and push the stamped part pushed from the groove 3 out to one side of the frame 1. The operator can set a slide (not shown in the figure) and a storage frame (not shown in the figure) on one side of the frame 1 to facilitate the transportation of the stamped part.
