Description

Technical Field

[0001] This utility model belongs to the field of metal spring processing technology, specifically relating to a metal product spring stamping device and the spring. Background Technology

[0002] Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to a material at room temperature, causing it to separate or plastically deform, thereby obtaining the desired part. When manufacturing metal springs, the metal needs to be stamped to change its shape and obtain a workpiece of the required shape and size. This requires the use of automatic metal spring stamping equipment.

[0003] The existing automatic stamping equipment for metal springs requires placing the metal strip on the surface of the equipment during use. After stamping, the strip springs are automatically cut and separated into individual parts using a mold. Then, tweezers and other tools are used to pick up the springs one by one and place them into the corresponding holes. Finally, they are sent into the positioning mold and bent into place. This not only poses safety hazards but also has a low degree of automation and reduces production efficiency. Utility Model Content

[0025] This specific embodiment is a metal product spring stamping device, the structural schematic diagram of which is shown below. Figures 1-5 As shown, the device is used for, such as Figure 1 The metal spring strip shown is processed to form a metal product spring. The spring is only connected to the strip on the left and right sides. It is processed by the following metal product spring stamping device. The device includes a base 1 and a stamping electric push rod 2 set on the top of the base 1. A lower die 3 is fixedly connected to the middle of the upper surface of the base 1. A first through hole 4 is opened in the middle of the upper surface of the lower die 3. A fixing block 5 is fixedly connected to the middle of the inner bottom wall of the first through hole 4. A movable plate 6 is set above the lower die 3. The telescopic end of the stamping electric push rod 2 is fixed to the movable plate 6. A U-shaped pressure block 7 is fixedly connected to the lower surface of the movable plate 6. The stamping electric push rod 2 is used to drive the U-shaped pressure block 7 to cooperate with the fixed block 5 to bend the metal spring sheet. Cutters 8 are fixedly connected to both sides of the U-shaped pressure block 7. The cutter 8 is used to cut the metal spring sheet. A feeding component 9 is provided on the left side of the fixed block 5. A discharge hopper 10 communicating with the first through hole 4 is installed on the right side of the base 1. The right side of the discharge hopper 10 is inclined downward. The feeding component 9 is used to push the bent metal spring sheet into the discharge hopper 10.

[0026] like Figure 1 and Figure 2As shown: In this embodiment, each of the four corners of the upper surface of the base 1 is fixedly connected to a column 101, and the top of the column 101 is fixedly connected to a top plate 102. The stamping electric push rod 2 is fixedly connected to the middle of the upper surface of the top plate 102. Each of the four corners of the movable plate 6 is provided with a second through hole 601, and the second through hole 601 is slidably sleeved on the outer surface of the column 101.

[0027] This allows the movable plate 6 to slide up and down along the column 101, preventing tilting and ensuring that the U-shaped pressure block 7 and the fixed block 5 can be accurately matched.

[0028] like Figure 1 and Figure 3 As shown: In this embodiment, multiple limiting posts 11 are rotatably connected to both the front and rear sides of the upper surface of the lower mold 3. The front and rear limiting posts 11 are used to limit the metal spring sheet.

[0029] When in use, the external spring feeding device conveys the metal spring strip to the lower die 3. At this time, the metal spring strip is located between the front and rear limit posts 11 on the lower die 3 to avoid misalignment. The rotation of the limit posts 11 can reduce friction.

[0030] like Figure 1 and Figure 4 As shown: In this embodiment, the four corners of the lower surface of the movable plate 6 are fixedly connected with the first telescopic rod 602, the bottom end of the first telescopic rod 602 is fixedly connected with the pressure ring 603, the outer surface of the first telescopic rod 602 is sleeved with the first spring 604, and the pressure ring 603 is provided with the clearance hole 605 corresponding to the limit post 11.

[0031] By activating the electric push rod 2 to extend, the movable plate 6, U-shaped pressure block 7 and pressure ring 603 move downward. When the pressure ring 603 contacts the metal spring strip, it presses it flat onto the lower die 3. At this time, the stamped metal spring strip is located on the fixed block 5 on the lower die 3. Due to the presence of the first telescopic rod 602 and the first spring 604, the movable plate 6 can continue to move downward.

[0032] like Figure 4 and Figure 5 As shown: In this embodiment, two second telescopic rods 701 are fixedly connected to the inner top wall of the U-shaped pressure block 7. The bottom end of the second telescopic rod 701 is fixedly connected to a pressure plate 702 corresponding to the fixed block 5. A second spring 703 is sleeved on the outer surface of the second telescopic rod 701.

[0033] After the stamping electric push rod 2 extends, the first telescopic rod 602 retracts and compresses the first spring 604 until the pressure plate 702 presses the metal spring sheet tightly onto the fixed block 5. Then the stamping electric push rod 2 continues to extend, the second telescopic rod 701 retracts and compresses the second spring 703, and then the U-shaped pressure block 7 cooperates with the fixed block 5 to bend the metal spring sheet downward.

[0034] like Figure 1 and Figure 3 As shown: In this embodiment, the feeding component 9 includes a feeding electric push rod 901 fixedly connected to the inner wall on the left side of the first through hole 4. The telescopic end of the feeding electric push rod 901 is fixedly connected to a U-shaped push block 902. The front and rear sides of the fixing block 5 are provided with through slots 903.

[0035] In this way, the electric push rod 901 extends and drives the U-shaped push block 902 to move into the through groove 903, pushing the metal spring sheet bent and attached to the fixed block 5 into the discharge hopper 10 for collection. This eliminates the need for workers to manually demold the stamped metal spring sheet, making it very convenient to use.

[0036] Working principle: During use, the external spring feeding device conveys the metal spring strip to the lower die 3. At this time, the metal spring strip is located between the front and rear limit posts 11 on the lower die 3. Then, the stamping electric push rod 2 is activated to extend, driving the movable plate 6, U-shaped pressure block 7 and pressure ring 603 to move downward. When the pressure ring 603 contacts the metal spring strip, it presses it flat onto the lower die 3. At this time, the stamped metal spring is located on the fixed block 5 on the lower die 3. Then, the stamping electric push rod 2 continues to extend, at which time the first telescopic rod 602 retracts and compresses the first spring 60. 4. The pressure plate 702 presses the metal spring sheet firmly onto the fixed block 5. Then, the second telescopic rod 701 retracts and compresses the second spring 703. Then, the U-shaped pressure block 7 cooperates with the fixed block 5 to bend the metal spring sheet downward. The cutters 8 on the left and right sides of the U-shaped pressure block 7 cut the metal spring sheet. Finally, the electric push rod 901 extends and drives the U-shaped push block 902 to move and push the bent metal spring sheet into the discharge hopper 10 for collection. Thus, the bending and stamping of the metal spring sheet is completed in one go. This not only has high safety, but also saves manpower and improves production efficiency.

[0037] All technical features in this embodiment can be freely combined according to actual needs.
