Description

Technical Field

[0001] This utility model belongs to the field of hard disk processing technology, and more specifically, it relates to a high-precision stamping forming machine for hard disk metal casing. Background Technology

[0002] The high-precision stamping forming machine for hard drive metal casings is a precision processing equipment specifically designed for hard drive metal protective casings. Its core technology uses high-speed stamping to achieve integrated forming of metal sheets, ensuring that the flatness, perpendicularity, and edge smoothness of the casing meet the standards, providing a reliable protective carrier for the internal components of the hard drive. It generally consists of a stamping machine body, a drive system, a mold, a stamping actuator, and a control system.

[0003] The existing application number is CN202223393342.3. This utility model relates to the technical field of metal sheet processing, and in particular to a high-efficiency and stable metal sheet stamping and forming equipment. It improves the stamping and forming effect of metal sheets, facilitates the collection of waste generated during metal sheet stamping, increases convenience, and enhances practicality. It includes a base plate, a worktable, a column, a top plate, a connecting plate, a mounting base, a punch, a stripper plate, a spring, a die, a fixed base, a power mechanism, a collection mechanism, and a guiding mechanism. The worktable is mounted on the base plate, the column is mounted on the worktable, the top plate is mounted on the column, the power mechanism is mounted on the top plate, the connecting plate is mounted on the output end of the power mechanism, the guiding mechanism is mounted on the top plate and connected to the power mechanism, the mounting base is mounted on the connecting plate, the punch is mounted on the mounting base, the stripper plate is slidably connected to the punch, the spring is mounted on the connecting plate and connected to the stripper plate, the fixed base is mounted on the worktable, and the die is mounted on the fixed base.

[0004] Based on the above, the positions of the upper and lower dies of the stamping machine need to be relatively fixed to ensure stamping accuracy. This design means that when workers pick up the formed parts after the stamping operation is completed, they must put their hands into the relatively enclosed space between the upper and lower dies, which is close to the stamping mechanism. On the one hand, the narrow space restricts hand movement and reduces the efficiency of picking up the parts. On the other hand, when workers put their hands in, they may accidentally touch the equipment switch or cause the mechanical parts to move unexpectedly, which may pose a potential risk of mechanical injury and seriously threaten their personal safety. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a high-precision stamping forming machine for hard drive metal casings. This solves the problem that existing stamping forming machines require relatively fixed upper and lower die positions to ensure stamping accuracy. This design means that after the stamping operation is completed, when workers retrieve the formed parts, they must reach their hands into the relatively enclosed space between the upper and lower dies, which is adjacent to the stamping mechanism. On the one hand, the narrow space restricts hand movement, resulting in low retrieval efficiency. On the other hand, when workers reach in, they may accidentally touch equipment switches or cause unexpected mechanical parts to move, posing a potential risk of mechanical injury and seriously threatening personal safety.

[0006] The purpose and effect of this utility model, a high-precision stamping forming machine for hard disk metal casings, are achieved by the following specific technical means: A high-precision stamping forming machine for hard drive metal casings includes a stamping machine body, a stamping cylinder, an upper die, a connecting slider, a lower die, an automatic pushing component, and an auxiliary lifting component. The stamping cylinder is fixedly connected to the lower part of the stamping machine body. The upper die is fixedly connected to the lower part of the piston rod of the stamping cylinder. Two connecting sliders are provided, and the two connecting sliders are slidably connected inside the stamping machine body. The lower die is fixedly connected above the two connecting sliders. The automatic pushing component is located below the first connecting component and inside the stamping machine body. The auxiliary lifting component is located inside the lower die.

[0007] Furthermore, the automatic pushing component includes: a first connecting member and a downward transmission rack; the first connecting member is fixedly connected to the right side of the upper mold; the downward transmission rack is fixedly connected to the lower right end of the first connecting member.

[0008] Furthermore, the automatic pushing component also includes: a first drive shaft and a downward drive gear; the first drive shaft is rotatably connected inside the main body of the press; the downward drive gear is coaxially fixedly connected to the right end of the first drive shaft, and the downward drive gear meshes with the downward drive rack.

[0009] Furthermore, the automatic pushing assembly also includes: a rearward transmission gear, a second connecting member, and a rearward transmission rack; the rearward transmission gear is coaxially and fixedly connected to the left end of the first transmission shaft; the second connecting member is fixedly connected to the lower mold; the front end of the rearward transmission rack is fixedly connected to the lower part of the second connecting member, and the rearward transmission rack meshes with the rearward transmission gear.

[0010] Furthermore, the auxiliary lifting assembly includes a lifting member and an operating rod; the bottom of the lifting member is slidably connected to the inside of the lower mold; the operating rod is fixedly connected to the right side of the lifting member, and the operating rod is slidably connected to the lower mold.

[0011] Furthermore, the auxiliary lifting assembly also includes: a tension spring; two tension springs are provided, with the tops of the two tension springs respectively fixedly connected to the bottom of the lifting component, and the bottoms of the two tension springs respectively fixedly connected to the inside of the lower mold.

[0012] Compared with the prior art, the present invention has the following beneficial effects: First, when the upper mold moves down, the lower mold is moved to the stamping position by the automatic pushing component. After stamping is completed, when the upper mold moves up, it pushes the lower mold to the front. This design allows workers to pick up the formed parts without having to reach into the core stamping area. It solves the problem of inconvenience in picking up and handling traditional fixed molds, avoids the safety hazards of hands reaching into dangerous areas, and improves the safety and convenience of operation.

[0013] Secondly, the operator can pull the operating lever to drive the lifting component to move upward, lifting the molded part in the groove of the lower mold. After the part is removed, pulling the spring can automatically reset the lifting component to be flush with the surface of the groove. This effectively solves the problem of difficulty in removing the molded part caused by the structure of the lower mold groove, reduces the posture adjustment and operation time during removal, and further improves the removal efficiency.

[0014] This utility model machine achieves automatic displacement of the lower mold along with the upper mold through an automatic pushing component, eliminating the need for workers to put their hands into dangerous areas. It also solves the problem of difficulty in retrieving workpieces from the groove of the lower mold with the help of an auxiliary lifting component. This not only improves the safety and convenience of operation, but also optimizes the retrieval efficiency, which helps to promote the efficient and safe development of the production process in the field of hard drive metal casing processing.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1

[0022] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a high-precision stamping forming machine for hard disk metal casings, including a stamping machine body 1, a stamping cylinder 2, an upper mold 3, a connecting slider 4, a lower mold 401, and an automatic pushing component; the stamping cylinder 2 is fixedly connected to the lower part of the stamping machine body 1; the upper mold 3 is fixedly connected to the lower part of the piston rod of the stamping cylinder 2; two connecting sliders 4 are provided, and the two connecting sliders 4 are slidably connected inside the stamping machine body 1 respectively; the lower mold 401 is fixedly connected above the two connecting sliders 4; the automatic pushing component is located below the first connecting member 301 and inside the stamping machine body 1.

[0023] The automatic pushing component includes: a first connecting member 301 and a downward transmission rack 302; the first connecting member 301 is fixedly connected to the right side of the upper mold 3; the downward transmission rack 302 is fixedly connected to the lower right end of the first connecting member 301.

[0024] The automatic pushing component also includes: a first drive shaft 5 and a downward drive gear 501; the first drive shaft 5 is rotatably connected inside the main body 1 of the press; the downward drive gear 501 is coaxially fixedly connected to the right end of the first drive shaft 5, and the downward drive gear 501 meshes with the downward drive rack 302.

[0025] The automatic pushing component also includes: a rearward transmission gear 502, a second connecting member 6, and a rearward transmission rack 601; the rearward transmission gear 502 is coaxially fixedly connected to the left end of the first transmission shaft 5; the second connecting member 6 is fixedly connected to the lower mold 401 below; the front end of the rearward transmission rack 601 is fixedly connected to the lower end of the second connecting member 6, and the rearward transmission rack 601 meshes with the rearward transmission gear 502.

[0026] The specific usage and function of this embodiment are as follows: In use, the hard drive metal casing plate is first placed inside the groove of the lower mold 401. Then, the stamping cylinder 2 is activated. As the piston rod of the stamping cylinder 2 drives the upper mold 3 downward, the first connecting piece 301 and the downward transmission rack 302 move downward synchronously. The downward transmission rack 302, through its meshing with the downward transmission gear 501, forms a gear and rack transmission mechanism that drives the first transmission shaft 5 to rotate. Under the guidance of the connecting slider 4 and the stamping machine body 1, the rotation of the first transmission shaft 5 is achieved through the meshing of the backward transmission rack 601 and the backward transmission gear 502, forming a gear and rack mechanism. The transmission mechanism drives the second connecting piece 6 and the lower mold 401 to move backward. When the top of the downward transmission rack 302 moves to disengage from the downward transmission gear 501, the lower mold 401 moves directly below the upper mold 3. Then, the stamping cylinder 2 drives the upper mold 3 to move downward, thereby stamping the metal casing of the hard drive. After the forming is completed, the stamping cylinder 2 drives the upper mold 3 to move upward. When the top of the downward transmission rack 302 moves to engage with the downward transmission gear 501, the lower mold 401 is driven to move forward. Then, the stamping cylinder 2 drives the upper mold 3 to move to the top, and the lower mold 401 is pushed forward for easy handling by the operator. Example 2
