Abstract
Description
Technical Field
[0001] This utility model relates to the field of computer appearance parts processing technology, and in particular to a computer appearance parts stamping machine with a material ejection structure. Background Technology
[0002] Computer exterior components mainly include monitor, keyboard, mouse, chassis, power button, USB port, audio port, and optical drive (if present). The production process of computer exterior components requires the use of stamping machines, including stamping the chassis and keyboard.
[0003] Current stamping machines form the appearance parts by driving the upper die to move down and impacting the lower die. In this process, the current equipment lacks the effect of stabilizing the part to be stamped before stamping, which can easily cause displacement. At the same time, after stamping, it needs to be manually removed, which is inconvenient and unsafe. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a computer appearance part stamping machine with a material ejection structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A computer appearance part stamping machine with a material ejection structure includes a machine body, a cylinder fixed to the top of the machine body, an upper pressure film fixed to the output end of the cylinder, a lower pressure film fixed to the machine body at a position corresponding to the upper pressure film, a pressing element installed at the upper front end of the lower pressure film, and an adjusting element installed on the machine body to adjust the pressing element.
[0007] The pressing component includes a mounting plate, a pressure plate is provided below the mounting plate, and two insert rods are fixed to the top of the pressure plate. The two insert rods pass through the mounting plate and are fixed to the same connecting plate.
[0008] As a further embodiment of this utility model, the top of the mounting plate is provided with a hole corresponding to the insertion rod, and a guide sleeve is fixed in the hole. The insertion rod passes through the guide sleeve, and a spring is sleeved on the part of the insertion rod that passes through the guide sleeve. The top of the spring is fixed to the bottom of the connecting plate, and the bottom of the spring is fixed to the top of the mounting plate.
[0009] As a further embodiment of this utility model, the adjusting component includes an electric push rod fixed to the outer wall of the machine body, a connecting plate fixed to the output end of the electric push rod, guide rods fixed to the bottom of both sides of the connecting plate, a first mounting arm and a second mounting arm fixed to the outer wall of the machine body, and an opening fixing block for the guide rods to pass through fixed on the first mounting arm and the second mounting arm, and the mounting plate fixed to the bottom of the two guide rods.
[0010] As a further embodiment of this utility model, the outer wall of the machine body is fixed with a guide block for the guide rod to pass through, which is beneficial to the movement of the guide rod.
[0011] As a further embodiment of this utility model, fixing strips are fixed at the top positions on both sides of the outer wall of the machine body, and a common stop strip is fixed between the two fixing strips.
[0012] As a further embodiment of this utility model, a mounting port is provided on one side of the pressure plate, and a push arm is provided in the mounting port. A stepper motor is fixed to the top of the pressure plate, and the output shaft of the stepper motor is fixed to the push arm through a coupling. A push rod is fixed to the bottom of the push arm. With a push arm driven by a stepper motor, after the pressing part returns to its highest position, the stepper motor drives the push arm to rotate clockwise. The push rod fixed to the bottom of the push arm can push the stamped outer part out from one side of the machine body for collection without manual removal, which is safer. It should be noted that when the pressing part moves down, the stepper motor needs to adjust the push arm to deflect counterclockwise to prevent the push rod from obstructing the downward movement.
[0013] The beneficial effects of this utility model are as follows:
[0014] This utility model, by employing a pressing component and an adjusting component, allows the pressure plate to approach the mounting plate under the drive of an electric push rod. The spring is stretched, and the connecting plate is pushed away from the mounting plate until the pressure plate and mounting plate are in contact, forming a pressure plate that presses against the workpiece to be stamped, providing a certain buffering effect and reinforcing the workpiece before stamping. After the cylinder drives the upper pressure film downwards to complete the stamping process, the pressing component is adjusted upwards to stop pressing the workpiece. This effectively solves the problems raised in the background technology, enabling stable pressing of the workpiece before stamping and preventing misalignment during the stamping process.
[0015] This utility model features a push arm driven by a stepper motor. After the pressing part returns to its highest position, the stepper motor drives the push arm to rotate clockwise. A push rod fixed at the bottom of the push arm pushes the stamped outer part out from one side of the machine body for collection, eliminating the need for manual removal and enhancing safety. Note that when the pressing part moves down, the stepper motor needs to be adjusted to deflect the push arm counterclockwise to prevent the push rod from obstructing the downward movement.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] Reference Figure 1-4 A computer appearance part stamping machine with a material ejection structure includes a machine body 1, a cylinder 2 fixed on the top of the machine body 1, an upper pressure film 3 fixed on the output end of the cylinder 2, a lower pressure film 4 fixed on the machine body 1 at the position corresponding to the upper pressure film 3, a pressing element 5 installed at the upper front end of the lower pressure film 4, and an adjusting element installed on the machine body 1 to adjust the pressing element 5.
[0024] The pressing component 5 includes a mounting plate 15, a pressure plate 14 is provided below the mounting plate 15, and two insert rods 18 are fixed to the top of the pressure plate 14. The two insert rods 18 pass through the mounting plate 15 and are fixed to the same connecting plate 16.
[0025] In this embodiment, the top of the mounting plate 15 is provided with a hole corresponding to the insertion rod 18, and a guide sleeve 17 is fixed in the hole. The insertion rod 18 is set through the guide sleeve 17, and a spring 19 is sleeved on the part of the insertion rod 18 that passes through the guide sleeve 17. The top of the spring 19 is fixed to the bottom of the connecting plate 16, and the bottom of the spring 19 is fixed to the top of the mounting plate 15.
[0026] In this embodiment, the adjusting component includes an electric push rod 6 fixed to the outer wall of the body 1. A connecting plate 8 is fixed to the output end of the electric push rod 6. Guide rods 7 are fixed to the bottom of both sides of the connecting plate 8. A first mounting arm 12 and a second mounting arm 13 are fixed to the outer wall of the body 1. An opening fixing block for the guide rods 7 to pass through is fixed on the first mounting arm 12 and the second mounting arm 13. A mounting plate 15 is fixed to the bottom of the two guide rods 7.
[0027] In this embodiment, the outer wall of the body 1 is fixed with a guide block 9 through which the guide rod 7 passes, which facilitates the movement of the guide rod 7.
[0028] In this embodiment, fixing strips 10 are fixed at the top positions on both sides of the outer wall of the body 1, and the same baffle 11 is fixed between the two fixing strips 10.
[0029] In this embodiment, a mounting port 20 is provided on one side of the pressure plate 14, and a push arm 21 is provided inside the mounting port 20. A stepper motor 22 is fixed to the top of the pressure plate 14. The output shaft of the stepper motor 22 is fixed to the push arm 21 through a coupling. A push rod 23 is fixed to the bottom of the push arm 21. With the push arm 21 driven by the stepper motor 22, after the pressing part 5 returns to the highest position, the stepper motor 22 drives the push arm 21 to rotate clockwise. The push rod 23 fixed to the bottom of the push arm 21 can push the stamped outer part out from one side of the machine body 1 for collection without manual removal, which is safer. It should be noted that when the pressing part 5 moves down, the stepper motor 22 needs to adjust the push arm 21 to deflect counterclockwise to prevent the push rod 23 from obstructing the downward movement.
[0030] Working Principle: This machine incorporates a pressing component 5 and an adjusting component. When using this equipment, the computer-related exterior part to be stamped is placed on the lower pressure film 4. First, the electric push rod 6 is activated. Through the guide rod 7 and connecting plate 8, the entire pressing component 5 moves downwards. Since the mounting plate 15 is directly fixed to the guide rod 7, as the guide rod 7 moves downwards, the mounting plate 15 also moves downwards. The pressure plate 14 below the mounting plate 15 first contacts the part to be stamped. Under the further drive of the electric push rod 6, the pressure plate 14 approaches the mounting plate 15, and the spring... 19 is stretched, and the connecting plate 16 is pushed away from the mounting plate 15 until the pressure plate 14 is in contact with the mounting plate 15, forming a contact squeeze of the pressure plate 14 on the part to be stamped, and playing a certain buffering role, thus strengthening the part to be stamped before stamping. After the cylinder 2 drives the upper pressure film 3 to move down to complete the stamping, the pressing part 5 is adjusted to move up to stop the squeezing of the part to be stamped, effectively solving the problem mentioned in the background technology. It can stabilize the squeezing of the part to be stamped before stamping and prevent deviation during the stamping process.
