[0002] In the category of electronic hardware materials, metal shrapnel belongs to metal stamping parts. It is generally made of stainless steel or manganese material after heat treatment and stamping. It is an important component of the switch. With the help of the conductivity of the metal shrapnel, it plays the role of a high-quality switch between the operator and the product. When producing metal shrapnel, relevant stamping molds are needed.

[0003] However, the existing metal spring stamping dies are not convenient for positioning the materials to be stamped when in use. During stamping, the materials are prone to shift in the horizontal direction. When the materials shift, the accuracy of the stamped metal springs will be reduced, affecting the quality of the metal springs and causing waste of materials. In view of this, we propose a metal spring stamping die that prevents misalignment. Utility Model Content

[0009] As a further improvement of the present technical solution, the pushing assembly includes a lifting plate, a lifting rod, a connecting rod, a accommodating rod and a connecting plate. The upper surface of the stamping lower die is provided with a forming groove corresponding to the stamping upper die. A lifting plate is provided inside the forming groove. The lower surface of the lifting plate is fixedly connected with a lifting rod.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 - Figure 5 As shown, this embodiment provides a metal spring stamping die for preventing dislocation, comprising a stamping box body 1, the inner wall of the stamping box body 1 is fixedly connected with a support plate 2, the interior of the stamping box body 1 is slidably connected with a pressing plate 3, and the lower surface of the pressing plate 3 and the upper surface of the support plate 2 are respectively provided with a stamping upper die 4 and a stamping lower die 5;

[0025] The inside of the stamping upper die 4 and the pressing plate 3 are symmetrically provided with movable grooves for the positioning rods 6 to move. The upper ends of the two positioning rods 6 are fixedly connected to the limiting blocks 7. The outsides of the two positioning rods 6 are movably sleeved with positioning springs 8. The two ends of the positioning springs 8 are respectively fixedly connected to the lower surface of the limiting blocks 7 and the upper surface of the pressing plate 3; during stamping, the positioning rods 6 can contact and position the material to be stamped as the pressing plate 3 moves downward to prevent the material from shifting and affecting the stamping quality.

[0026] Among them, the lower ends of the two positioning rods 6 are fixedly sleeved with rubber sleeves 9, and the lower surface of the stamping upper die 4 is symmetrically provided with reserved grooves adapted to the rubber sleeves 9; when the positioning rods 6 are in contact with the material, the set rubber sleeves 9 can ensure the stability of the material positioning, and the set reserved grooves can prevent the rubber sleeves 9 from blocking the downward movement of the stamping upper die 4 when the stamping upper die 4 is in contact with the stamping lower die 5, thereby affecting the normal progress of the stamping.

[0027] A pusher assembly for ejecting the metal spring after stamping is provided below the pressing plate 3. The pusher assembly can eject the stamped material from the stamping lower die 5 after the stamping is completed, without the need for the staff to manually deduct the material, thereby ensuring the stamping efficiency.

[0028] The above working principle: when in use, the material to be stamped is placed on the stamping lower die 5, and then the pressing plate 3 moves downward, driving the stamping upper die 4 to move downward, and cooperates with the stamping lower die 5 to stamp the material. While the stamping upper die 4 moves downward, it drives the two positioning rods 6 to move downward to contact and position the material. Under the action of the positioning spring 8 and the limit block 7, the positioning rod 6 can ensure the contact positioning of the material while not affecting the contact use of the stamping upper die 4 and the stamping lower die 5. The contact positioning of the material can prevent the material from being offset during stamping and affecting the accuracy of the hardware spring piece, resulting in waste of material.

[0029] In order to facilitate the removal of the stamped metal spring pieces from the stamping lower die 5 after the stamping is completed, the pushing assembly includes a lifting plate 10, a lifting rod 11, a connecting rod 12, a accommodating rod 13 and a connecting plate 14. The upper surface of the stamping lower die 5 is provided with a forming groove corresponding to the stamping upper die 4, and a lifting plate 10 is provided inside the forming groove. The lower surface of the lifting plate 10 is fixedly connected with a lifting rod 11. The lower end of the lifting rod 11 passes through the stamping lower die 5 and the support plate 2 and extends to the bottom of the support plate 2. After the stamping is completed, the lifting rod 11 can drive the lifting plate 10 to move upward to eject the stamped metal spring pieces from the stamping lower die 5 to ensure the efficiency of the stamping.

[0030] Taking into account the need to facilitate the pushing of the lifting rod 11 after the stamping is completed, the lower surface of the pressing plate 3 is symmetrically fixedly connected with a connecting rod 12, and the interior of the support plate 2 is symmetrically provided with reserved grooves for the accommodating rod 13 to move, and the interior of the accommodating rod 13 is provided with an accommodating groove for the connecting rod 12 to move. The lower surfaces of the two accommodating rods 13 are fixedly connected with connecting plates 14, and the lower ends of the lifting rods 11 are fixedly connected to the upper surfaces of the connecting plates 14. When the pressing plate 3 moves downward and the stamping upper die 4 performs stamping, the two connecting rods 12 can move in the reserved grooves. After the stamping is completed, the pressing plate 3 moves upward, which can drive the connecting rod 12 to move in the reserved grooves, and when the connecting rod 12 rises to a certain position, it can drive the accommodating rod 13 to move upward, thereby making the connecting plate 14 move upward, thereby pushing the lifting rod 11 to move upward, and there is no need for staff to manually operate the lifting rod 11, reducing safety hazards.

[0031] In order to ensure the stability of the pressing plate 3 when it moves downward, a hydraulic cylinder 15 is fixedly installed on the inner top of the stamping box 1. The telescopic end of the hydraulic cylinder 15 is fixedly connected to the upper surface of the pressing plate 3. The inner walls on both sides of the stamping box 1 are fixedly connected with guide rods 16. The outer wall of the pressing plate 3 is provided with a plurality of guide grooves compatible with the guide rods 16. When in use, the hydraulic cylinder 15 is started to push the pressing plate 3 to drive the stamping upper die 4 to move downward to stamp the material. When the pressing plate 3 moves downward, the guide rods 16 provided can cooperate with the guide grooves to guide the downward movement of the pressing plate 3, thereby ensuring the stability of the pressing plate 3 when it moves downward and increasing the stamping effect of the stamping lower die 5.

[0032] In order to facilitate the processing of hardware spring pieces of different sizes during operation, the stamping upper die 4 is detachably fixedly connected to the pressure plate 3 by bolts, and the stamping lower die 5 is detachably fixedly connected to the support plate 2 by bolts. When the stamping upper die 4 and the stamping lower die 5 are damaged, or when it is necessary to process hardware spring pieces of different sizes, the stamping upper die 4 and the stamping lower die 5 fixed by bolts can be easily and quickly disassembled and replaced, which is convenient for the staff to use.

[0033] In addition, it is necessary to ensure the accuracy of the contact between the stamping lower die 5 and the stamping upper die 4, so the upper surface of the stamping lower die 5 is fixedly connected with a positioning protrusion 17, and the lower surface of the stamping upper die 4 is provided with a positioning groove corresponding to the positioning protrusion 17. When the stamping upper die 4 moves downward and approaches the stamping lower die 5, the set positioning protrusion 17 will be stuck in the positioning groove, so that the stamping lower die 5 and the stamping upper die 4 fit more tightly and accurately.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
