Description

Technical Field

[0001] This utility model belongs to the field of host machine manufacturing technology, and in particular relates to a host machine U-frame stamping die. Background Technology

[0002] The host refers to the main body of a computer excluding input and output devices. It is also the control box used to house the motherboard and other major components. It typically includes the CPU, memory, motherboard, hard drive, optical drive, power supply, chassis, cooling system, and other input and output controllers and interfaces. The U-frame is one of the most common structures in the host, mainly used to install the CPU, memory, and other components. The U-frame is generally manufactured by stamping molds.

[0003] The existing authorization announcement document CN221336281U discloses a continuous stamping die, including a base plate and a U-shaped frame. The U-shaped frame is provided on the upper surface of the base plate, and an electro-hydraulic push rod is provided through the upper surface of the U-shaped frame. A trapezoidal die is installed on the lower surface of the electro-hydraulic push rod. The die body is installed on the upper surface of the base plate, and a cylindrical die is provided through the vertical surface of the die body. A notch is opened on the arc surface of the cylindrical die.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The continuous stamping die mentioned above forms the workpiece through a trapezoidal die and a die body. However, in use, since the dimensions of the trapezoidal die and the die body are fixed, it can only stamp out a U-frame of one size. Since the U-frame in the main machine has a variety of sizes, its applicability is small and its practicality is low.

[0006] 2. The continuous stamping die mentioned above forms the workpiece through a trapezoidal die and a die body. However, it lacks a structure to limit the workpiece during use, requiring the operator to manually position the workpiece. Its accuracy is poor and it is easy to accidentally injure the operator.

[0007] To address these issues, we provide a main unit U-frame stamping die. Utility Model Content

[0008] The purpose of this utility model is to provide a main unit U-frame stamping die, which drives the lower dies to move in opposite directions or back to back through the first threaded rod, and drives the upper dies to move in opposite directions or back to back through the second threaded rod, thereby adjusting the size of the processed U-frame and solving the problem of the existing U-frames that are not easy to stamp. At the same time, the positioning plate and pulley are driven to move through the sleeve rod and the fourth threaded rod, and the positioning plate and pulley are used to position the workpiece to be stamped, thus solving the problem of the existing workpieces that are not easy to position.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0011] A further feature of this invention is that: both sides of the rear end face of the first mounting frame are fixedly connected to fixing rods, and the rear ends of the fixing rods are fixedly connected to both sides of the front end face of the vertical support arm of the L-shaped frame.

[0012] A further feature of this invention is that a hydraulic cylinder is fixedly connected to the top of the longitudinal support arm of the L-shaped frame, the output shaft of the hydraulic cylinder is fixedly connected to the center of the upper surface of the lifting plate, and sliding rods are fixedly connected to both sides of the upper surface of the lifting plate. The top of the sliding rods passes through the longitudinal support arm of the L-shaped frame and is fixedly connected to a first limiting plate. A second mounting frame is fixedly connected to the lower surface of the lifting plate.

[0013] The present invention is further configured as follows: a first threaded rod is rotatably connected inside the first mounting frame, both ends of the first threaded rod extend to the outer sides of the first mounting frame and are fixedly connected to a first knob, both sides of the outer wall of the first threaded rod are threadedly connected to a first slider, the top of the first slider is fixedly connected to the bottom of the lower mold, a second threaded rod is rotatably connected inside the second mounting frame, both ends of the second threaded rod extend to the outer sides of the second mounting frame and are fixedly connected to a second knob, both sides of the outer wall of the second threaded rod are threadedly connected to a second slider, the bottom of the second slider is fixedly connected to the top of the upper mold.

[0014] A further feature of this invention is that a connecting plate is snapped between the two lower molds and between the two upper molds. An installation rod extends through both sides of the end face of the connecting plate. The front end of the installation rod extends to the front end of the lower mold and the upper mold and is threaded with a fastening nut. The rear end of the installation rod extends to the rear end of the lower mold and the upper mold and is fixedly connected with a second limiting plate.

[0015] A further feature of this invention is that: both sides of the top of the stamping table are threadedly connected to a third threaded rod via a mounting seat; one end of each third threaded rod is fixedly connected to a first handwheel; and the other end of each third threaded rod is fixedly connected to the lower side of the outer wall of a moving block; the moving block is slidably connected to both sides of the top of the stamping table.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by setting up a stamping assembly, removes the connecting plate from the lower and upper dies. Rotating the first and second knobs respectively drives the first and second threaded rods to rotate. The first and second threaded rods, through the first and second sliders respectively, drive the lower and upper dies to move in opposite directions or in opposite directions. When the distance between the lower and upper dies reaches a specified value, the first and second knobs are stopped, and the connecting plate of the corresponding length is installed between the lower and upper dies. This enables the stamping of U-frames of different sizes, facilitating the processing of the main unit's U-frame.

[0020] 2. This utility model, by setting a positioning component, places the workpiece on the placement plate and rotates the drive rod. The drive rod drives two sleeve rods to rotate synchronously through a synchronous belt. The sleeve rods drive the positioning plate to move through the fourth threaded rod, so that the positioning plate drives the pulleys to abut against the front and rear ends of the workpiece, thereby realizing the positioning of the workpiece. This facilitates the positioning of U-frame workpieces and makes it easier to stamp the U-frame. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this is the first embodiment of the present invention.
