Description

Technical Field

[0001] The present invention relates to the technical field of tantalum capacitor housing packaging, and specifically relates to a stamping fixture for a capacitor packaging housing. Background Art

[0002] The packaging form and size of tantalum capacitors can be understood by checking their packaging form and size parameters. Common packaging methods include DIP type and SMD type. DIP type tantalum capacitors usually have the shape of a cylindrical electrolytic capacitor, while SMD type uses a chip or chip - type shape, which is suitable for surface - mount applications and can achieve a higher packaging density on printed circuit boards;

[0003] A stamping fixture for a capacitor packaging housing is a device used to fix and position the capacitor housing material to maintain its shape and position during the stamping process.

[0004] Conventionally, in the stamping process of capacitor packaging housings, due to the limitations of the fixture, different specifications of fixtures need to be used for stamping housings of different specifications, which causes great inconvenience, affects the overall operation efficiency, and increases additional production costs at the same time. Summary of the Invention

[0005] The purpose of the present invention is to provide a stamping fixture for a capacitor packaging housing to solve the problems raised in the above - mentioned background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A stamping fixture for a capacitor packaging housing, including a device frame and a movable clamping frame. On the left and right sides of the middle part inside the device frame, guide frames are symmetrically installed. The movable clamping frame is arranged in the middle of the guide frames, and adjustment screws horizontally penetrate through both sides of the movable clamping frame. At the top end inside the device frame, an upper die set is installed, and at the bottom end inside the device frame, a lower die set is installed. The movable clamping frame includes a support plate, guide sliders, a connecting plate, and an anti - slip clamping plate. Guide sliders are arranged at both ends of the support plate, a connecting plate is arranged on one side of the middle part of the support plate close to the vertical central axis of the device frame, and an anti - slip clamping plate is installed at the end of the connecting plate far from the support plate.

[0007] Further, the device frame includes a movable plate, a docking plate, guide rods, and a fixed base. A docking plate is arranged in the middle of the top of the movable plate, guide rods are vertically installed at the left and right ends of the movable plate, and the bottom ends of the guide rods are connected to the fixed base.

[0008] Further, the docking plate and the movable plate are fixedly connected, and mounting holes for connecting and combining with an external hydraulic device are opened at the four diagonal corners of the docking plate.

[0009] Further, a sliding connection is formed between the movable plate and the guide rod, and the bottom of the guide rod is fixed to one end of the top of the fixed base.

[0010] Further, the upper module is fixedly installed in the middle of the bottom of the movable plate, and the lower module is installed in the middle of the top of the fixed base.

[0011] Further, the guide frame includes a stable frame, a support guide rail and a sliding sleeve member. The support guide rails are symmetrically installed on the left and right inside the stable frame, and a sliding sleeve member is installed in the middle of one side of the stable frame away from the vertical central axis of the device frame. Moreover, the guide rod vertically slides through the middle of the sliding sleeve member.

[0012] Further, a welded connection is formed between the sliding sleeve member and the stable frame, and the support guide rail is horizontally and fittingly installed on the inner side of the stable frame. Moreover, a slotted embedded structure is adopted to connect and combine the guide slider and the support guide rail.

[0013] Further, the adjusting screw rod is arranged in a double-direction screw rod structure, and the adjusting screw rod horizontally threadedly penetrates through the left and right ends of the support plate and the anti-slip clamping plate respectively. Moreover, an integral structure is adopted among the support plate, the guide slider and the connecting plate.

[0014] Further, the operation method is as follows: Place the encapsulation shell material to be processed between two groups of movable clamping frames symmetrically arranged on the left and right. According to the size of the material, rotate the adjusting screw rods installed on both sides in the horizontal direction. The two groups of adjusting screw rods arranged in a double-direction screw rod structure horizontally penetrate through the two ends of the support plate and the anti-slip clamping plate, so that the two groups of movable clamping frames will respectively move left and right in the horizontal direction along the two ends of the adjusting screw rod. The movable clamping frame uses the guide sliders at both ends of the support plate to be slidably connected with the support guide rail through a slotted embedded structure. After the hydraulic device connected to the top of the movable plate through the docking plate starts to operate, it drives the upper module in the middle of the bottom of the movable plate to vertically push down in the vertical direction along the four groups of arranged guide rods, and dock with the lower module installed in the middle of the top of the fixed base, so as to realize stamping processing on the material clamped between the movable clamping frames. During this process, the guide frame equipped with the movable clamping frame uses the sliding sleeve member on one side of the stable frame to move along the surface of the guide rod to ensure the accuracy and movement stability of the stamping docking between the upper module and the lower module, and avoid unnecessary structural interference to the upper module and the lower module.

[0015] The present invention provides a stamping and forming fixture for a capacitor encapsulation shell, having the following beneficial effects:

[0016] 1. In the present invention, inside the guide frames symmetrically arranged on the left and right, movable clamping frames are symmetrically arranged on the left and right. At the same time, adjusting screws horizontally penetrate through both sides of the two groups of movable clamping frames. Since the adjusting screws horizontally thread through the left and right ends of the support plate and the anti-slip clamping plate respectively, when the adjusting screws are rotated axially horizontally, the movable clamping frames connected at both ends can be driven to perform left and right translation activities in the horizontal direction. By using this structure, appropriate adjustments can be made within a certain adjustment range according to the size of the encapsulation housing material, and it can be stably clamped and fixed, ensuring both the stability of processing and the flexibility and applicability of the device structure, thereby reducing production costs as much as possible while ensuring the operation efficiency.

[0017] 2. In the present invention, through the use of the guide frames, the movable clamping frames are connected to the support rails inside the stable frame by the guide sliders at both ends of the support plate. Thus, while rotating the adjusting screws and driving the movable clamping frames at both ends to move, the guide sliders will slide along the surface of the support rails. By using the above structure, the flexibility of the adjustment of the movable clamping frames can be maximally ensured while ensuring the stability of the structure. And since the entire guide frame is slidably sleeved on the surface of the guide rod by the sliding sleeve member, when the upper module and the lower module are docked under the push of the external hydraulic structure and stamping processing is carried out, the guide frame itself will also move adaptively, providing sufficient adjustment and stable support in this way while avoiding structural interference during the stamping processing of the encapsulation materials of the upper module and the lower module, so as to improve the flexibility of the device.

[0024] The following further describes in detail the implementation manners of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] As Figures 1 to 5 shown, a stamping fixture for a capacitor packaging shell includes a device frame 1 and a movable clamping frame 3. Guide frames 2 are symmetrically installed on the left and right in the middle of the inner side of the device frame 1. The movable clamping frame 3 is arranged in the middle of the inside of the guide frame 2, and adjusting screws 4 horizontally penetrate through both sides of the movable clamping frame 3. An upper module 5 is installed at the top end inside the device frame 1, and a lower module 6 is installed at the bottom end inside the device frame 1. The movable clamping frame 3 includes a support plate 301, guide sliders 302, a connecting plate 303, and an anti-slip clamping plate 304. Guide sliders 302 are arranged at both ends of the support plate 301, and a connecting plate 303 is arranged on one side of the middle of the support plate 301 close to the vertical central axis of the device frame 1. An anti-slip clamping plate 304 is installed at the end of the connecting plate 303 away from the support plate 301. The adjusting screw 4 is arranged in a bidirectional screw structure, and the adjusting screw 4 horizontally threadedly penetrates through the left and right ends of the support plate 301 and the anti-slip clamping plate 304 respectively. The support plate 301, the guide sliders 302, and the connecting plate 303 are integrally structured. When the adjusting screw 4 is rotated horizontally in the axial direction, the movable clamping frame 3 connected at both ends can be driven to perform left and right translation activities in the horizontal direction. With the use of this structure, appropriate adjustments can be made according to the size of the packaging shell material within a certain adjustment range, and it can be stably clamped and fixed.

[0026] As Figures 1 to 5As shown, the device frame 1 includes a movable plate 101, a docking plate 102, a guide rod 103 and a fixed base 104. The docking plate 102 is arranged in the middle of the top of the movable plate 101, and the guide rods 103 are vertically installed at the left and right ends of the movable plate 101, and the bottom of the guide rod 103 is connected to the fixed base 104, the docking plate 102 and the movable plate 101 are fixedly connected, and the four diagonal portions of the docking plate 102 are provided with mounting holes for connecting and assembling with an external hydraulic device, the movable plate 101 and the guide rod 103 are slidably connected, and the bottom of the guide rod 103 is fixed to one end of the top of the fixed base 104, the upper mold group 5 is fixedly installed in the middle of the bottom of the movable plate 101, and the lower mold group 6 is installed in the middle of the top of the fixed base 104, the guide frame 2 includes a stabilizing frame 201, a supporting guide rail 202 and a sliding sleeve member 203, and the left and right sides of the interior of the stabilizing frame 201 are fixedly connected. It is said that a support guide rail 202 is installed, and a sliding sleeve component 203 is installed in the middle of one side of the stabilizing frame 201 away from the vertical central axis of the device frame 1, and the guide rod 103 slides vertically through the middle of the sliding sleeve component 203, the sliding sleeve component 203 and the stabilizing frame 201 are welded, and the support guide rail 202 is horizontally installed on the inner side of the stabilizing frame 201, and the guide slider 302 and the support guide rail 202 are connected to each other by a slotted embedded structure, so that when the adjusting screw 4 is screwed and the movable clamping frames 3 at both ends are driven to move, the guide slider 302 will slide along the surface of the support guide rail 202, and at the same time, as the upper mold group 5 and the lower mold group 6 are connected and stamped under the push of the external hydraulic structure, the guide frame 2 itself will also move with self-adaptation, which maximizes the flexibility of the movable clamping frame 3 while ensuring the stability of the structure.

[0027] In summary, if Figures 1 to 5 As shown, the stamping and forming fixture of the capacitor packaging shell, when in use, first place the packaging shell material to be processed between the two groups of movable clamping frames 3 set symmetrically on the left and right, and then, according to the size of the material, screw the adjusting screws 4 installed on both sides in the horizontal direction. Since the two groups of adjusting screws 4 are set with a bidirectional screw structure and horizontally penetrate the two ends of the support plate 301 and the anti-slip clamping plate 304, the two groups of movable clamping frames 3 can respectively achieve left and right translation in the horizontal direction along the two ends of the adjusting screw 4. At the same time, the entire movable clamping frame 3 is connected to the support rail 202 by the grooved embedded structure of the guide slider 302 at the two ends of the support plate 301. With this structural setting, the guide slider 302 can slide along the surface of the support rail 202 while providing good structural support, so as to ensure the structural support and stability of the movable clamping frame 3 inside the guide frame 2, and ensure that the movable clamping frame 3 inside the guide frame 2 can be flexibly adjusted, so as to achieve adjustment according to the size of the material and clamp and fix it on the left and right sides;

[0028] Then, after the hydraulic device connected to the top of the movable plate 101 through the docking plate 102 starts to operate, it will drive the upper die set 5 in the middle of the bottom of the movable plate 101 to vertically push down in the vertical direction along the four groups of guide rods 103 disposed, and dock with the lower die set 6 installed in the middle of the top of the fixed base 104, so as to realize the stamping process of the material clamped in the middle of the movable clamp 3. During this process, the guide frame 2 equipped with the movable clamp 3 will use the sliding sleeve member 203 on one side of the stable frame 201 to move along the surface of the guide rod 103 to ensure the accuracy and moving stability of the stamping docking between the upper die set 5 and the lower die set 6, and also avoid causing unnecessary structural interference to the upper die set 5 and the lower die set 6, thereby ensuring the flexibility of the structure.
