Description

Technical Field

[0001] This utility model relates to the technical field of aircraft engine skid plate processing equipment, and in particular to a processing device for aircraft engine skid plates. Background Technology

[0002] Aircraft engines are used in aircraft to provide power. As a crucial component of aircraft, aircraft engines typically require high stability to enhance aircraft safety. Aircraft engine guards are used to protect the engine and improve its stability.

[0003] Aircraft engine skid plates are typically made of high-strength, lightweight materials and are usually formed using stamping. During the processing of the skid plates, punching holes is often required. Existing punching equipment can only punch holes in the skid plates; it cannot position the skid plates correctly during the punching process, resulting in low positional accuracy.

[0004] Therefore, existing protective plate processing equipment suffers from the technical problem of low punching accuracy. Utility Model Content

[0005] This utility model provides a processing device for aircraft engine skid plates, which solves the technical problem of low punching accuracy in existing skid plate processing equipment.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A processing apparatus for aircraft engine skid plates, comprising a frame;

[0008] A stamping assembly, which is disposed on the frame and is provided with a punch;

[0009] The mold is mounted on the frame and has a discharge hole located directly below the punch, and the discharge hole engages with the punch.

[0010] The stamping assembly further includes a pre-punch rod that forms a positioning recess on the material to be stamped and a positioning rod that mates with the hole formed by the punch. The pre-punch rod and the positioning rod are located on both sides of the punch, respectively.

[0011] The height of the lower end of the pre-punch rod is higher than the height of the lower end of the punch.

[0012] The lower end of the punch is higher than the lower end of the positioning rod.

[0013] Preferably, the stamping assembly further includes a stamping base, the stamping base being provided with a guide rod, and the frame being provided with a guide hole that cooperates with the guide rod.

[0014] Preferably, the guide rod has a polygonal cross-sectional shape, and there are four guide rods, which are evenly arranged around the punch.

[0015] Preferably, the punch is disposed on the stamping base, and the punch is located at the center of the stamping base. The punch and the stamping base are an integral structure, or the punch is fixed to the stamping base by bolts.

[0016] Preferably, the stamping base is further provided with a pressure plate for pressing the material to be stamped, and an elastic element is provided between the pressure plate and the stamping base. The pressure plate is located between the stamping base and the mold.

[0017] Preferably, the pressure plate is sleeved on the punch, the elastic element is a spring, one end of the elastic element is fixed to the stamping seat, and the other end of the elastic element is fixed to the pressure plate.

[0018] Preferably, the positioning rod is slidably connected to the stamping seat in a direction close to or away from the punch. The stamping seat is provided with a slide rail, the positioning rod is provided with a slide groove that cooperates with the slide rail, and the stamping seat is also provided with a locking screw to lock the positioning rod to the stamping seat.

[0019] Preferably, the positioning rod is provided with a slide block, the slide groove is provided in the slide block, the stamping seat is provided with a cavity to accommodate the slide block, the slide rail is provided in the cavity, and the locking screw locks the slide block by friction.

[0020] Preferably, the slide and the positioning rod are an integral structure, the positioning rod and the pre-punch rod have the same diameter, and the lower end of the positioning rod is provided with a spherical guide head, which is an integral structure with the positioning rod.

[0021] Preferably, the pre-punch rod is slidably connected to the stamping seat in a direction close to or away from the punch, and the stamping seat is provided with a positioning screw to lock the pre-punch rod to the stamping seat, and the diameter of the pre-punch rod is smaller than the diameter of the punch.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] By setting a positioning rod, and with the lower end of the punch lower than the lower end of the positioning rod, when punching, after the first hole on the guard plate is punched, the guard plate moves a certain distance toward the positioning rod before punching the next hole. The positioning rod allows the guard plate to be positioned by cooperating with the previous hole during punching, thus effectively improving the punching accuracy of the guard plate processing device.

[0024] By setting a pre-punch rod, a recess is formed on the guard plate before punching, i.e., a positioning recess. After the positioning recess is formed on the guard plate, the punch has higher punching accuracy when punching the guard plate, thereby further improving the punching accuracy of the processing equipment.

[0025] The pre-punch rod, positioning rod, and punch are all part of the stamping assembly. The pre-punch rod, punch, and positioning rod can be driven by the same equipment, eliminating the need for a separate drive motor. This simplifies the structure of the processing equipment and makes it easier to maintain. Attached Figure Description

[0037] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0038] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0039] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] Reference Figures 1 to 7 As shown, a processing apparatus for a protective plate for an aircraft engine includes a frame 1;

[0041] A stamping assembly 2 is disposed on the frame 1 and is provided with a punch 21;

[0042] The mold 11 is disposed on the frame 1. The mold 11 is provided with a discharge hole 111, which is located directly below the punch 21 and cooperates with the punch 21.

[0043] The stamping assembly 2 further includes a pre-punch rod 22 that forms a positioning recess on the material to be stamped and a positioning rod 23 that mates with the hole formed by the punch 21. The pre-punch rod 22 and the positioning rod 23 are located on both sides of the punch 21, respectively.

[0044] The height of the lower end of the pre-punch rod 22 is higher than the height of the lower end of the punch 21;

[0045] The lower end of the punch 21 is higher than the lower end of the positioning rod 23.

[0046] Understandably, the pre-punch rod 22 is used to form a recess on the guard plate, namely a positioning recess. The positioning recess has a shallow depth, so the positioning recess will not cause deformation of the guard plate during the forming process.

[0047] In some embodiments, the stamping assembly 2 can be driven by a hydraulic press, and the stamping assembly 2 moves up and down relative to the frame 1 to complete the stamping operation.

[0048] Understandably, during the stamping process of the guard plate, the guard rod is first placed on the mold 11, and the first position to be punched is located directly below the pre-punch rod 22. The stamping assembly 2 moves downward, and the pre-punch rod 22 forms a positioning recess on the guard plate.

[0049] The stamping assembly 2 moves upward, the pre-punch rod 22 disengages from the guard plate, and moves the guard plate a certain distance so that the positioning recess is located directly below the punch 21. The stamping assembly 2 continues to move downward. During the downward movement of the stamping assembly 2, the punch 21 first forms a hole on the guard plate, and then the pre-punch rod 22 forms a positioning recess at the next position on the guard plate.

[0050] The stamping assembly 2 moves upward again, and the pre-punch rod 22 and the punch 21 disengage from the guard plate. The guard plate moves another distance, at which point the hole formed on the guard plate is directly below the positioning rod 23, and the positioning recess is directly below the punch 21.

[0051] The stamping assembly 2 moves down again. During the downward movement of the stamping assembly 2, the positioning rod 23 first engages with the hole on the guard plate to position the guard plate. Then, the punch 21 forms a hole at the current positioning recess. Finally, the pre-punch rod 22 forms a positioning recess on the guard plate. This process is repeated to complete the punching operation of the guard plate.

[0052] Because the positioning rod 23 can position the guard plate during the punching process, the punching accuracy is effectively improved.

[0053] Reference Figures 1 to 7 As shown, in some embodiments, the stamping assembly 2 further includes a stamping seat 24, the stamping seat 24 is provided with a guide rod 25, and the frame 1 is provided with a guide hole 12 that cooperates with the guide rod 25.

[0054] The hydraulic press drives the stamping seat 24 to move back and forth. Typically, the piston rod of the hydraulic press is fixed to the stamping seat 24, for example, by bolts.

[0055] In some embodiments, the cross-sectional shape of the guide rod 25 is polygonal, and there are four guide rods 25, which are evenly arranged around the punch 21.

[0056] The guide rod 25 and the stamping seat 24 can be an integral structure.

[0057] In some embodiments, the punch 21 is disposed on the stamping seat 24, and the punch 21 is located at the center of the stamping seat 24. The punch 21 and the stamping seat 24 are an integral structure, or the punch 21 is fixed to the stamping seat 24 by bolts.

[0058] When frequent replacement or maintenance of punch 21 is required, punch 21 can be fixed to stamping seat 24 with bolts.

[0059] In some embodiments, the stamping base 24 is further provided with a pressure plate 211 for pressing the material to be stamped, and an elastic element 212 is provided between the pressure plate 211 and the stamping base 24. The pressure plate 211 is located between the stamping base 24 and the mold 11.

[0060] The pressure plate 211 serves as an auxiliary positioning device. During the punching process, the pressure plate 211 first contacts the guard plate and applies a certain pressure to the guard plate to achieve positioning of the guard plate. Then, the punch 21 performs the punching operation.

[0061] In some embodiments, the pressure plate 211 is sleeved on the punch 21, the elastic element 212 is a spring, one end of the elastic element 212 is fixed to the stamping seat 24, and the other end of the elastic element 212 is fixed to the pressure plate 211.

[0062] In some embodiments, the positioning rod 23 is slidably connected to the stamping seat 24 in a direction close to or away from the punch 21. The stamping seat 24 is provided with a slide rail 261, and the positioning rod 23 is provided with a slide groove 231 that cooperates with the slide rail 261. The stamping seat 24 is also provided with a locking screw 27 for locking the positioning rod 23 to the stamping seat 24.

[0063] The positioning rod 23 is slidably connected to the stamping seat 24. The distance between the positioning rod 23 and the punch 21 can be adjusted to adapt to the forming operation of the guard plate with different hole spacing.

[0064] In some embodiments, the positioning rod 23 is provided with a slide block 232, the slide groove 231 is provided in the slide block 232, the stamping seat 24 is provided with a cavity 26 for accommodating the slide block 232, the slide rail is provided in the cavity 26, and the locking screw 27 locks the slide block 232 by friction. The slide rail and the stamping seat 24 are an integral structure.

[0065] Reference Figures 1 to 7 As shown, in some embodiments, the slide block 232 and the positioning rod 23 are an integral structure, the positioning rod 23 has the same diameter as the pre-punch rod, and the lower end of the positioning rod 23 is provided with a spherical guide head, which is an integral structure with the positioning rod 23.

[0066] The diameter of the spherical guide head is equal to or smaller than that of the positioning rod 23, and the spherical guide head and the positioning rod 23 are an integral structure. The spherical guide head allows the positioning rod 23 to smoothly enter the hole in the guard plate.

[0067] The slide 232 is secured by at least four locking screws 27. The more locking screws 27 that secure the slide 232, the higher the positional accuracy of the slide 232, and the less likely the slide 232 is to misalign during punching operations.

[0068] In some embodiments, the pre-punch rod 22 is slidably connected to the stamping seat 24 in a direction close to or away from the punch 21. The stamping seat 24 is provided with a positioning screw for locking the pre-punch rod 22 to the stamping seat 24. The diameter of the pre-punch rod 22 is smaller than the diameter of the punch 21.

[0069] The pre-punch rod 22 can be slidably mounted on the stamping seat 24 with the same structure as the positioning rod 23.

[0070] The pre-punch rod 22 is typically small in diameter and has a sharper lower end so that excessive force is not required when forming a positioning recess on the guard plate.

[0071] In some embodiments, the discharge hole 111 is used to discharge the waste material punched down by the punch 21.

[0072] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0073] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here.
