Description

Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a centering beater. Background Art

[0002] The existing sheet metal centering and tapping mechanism generally uses fixed-position centering fingers, and the centering fingers cannot be adjusted in the width direction of the sheet. This limitation makes it impossible to effectively achieve accurate positioning of the sheet when the tapping position of the centering fingers happens to be at the notch position of the sheet, because the notch cannot provide stable support and positioning.

[0003] Inaccurate blank positioning directly affects subsequent processing steps. During the stamping process, if the blank is not positioned accurately, it may lead to dimensional deviations, irregular shapes, and even scrap of the stamped parts.

[0004] Inaccurate positioning may also affect production efficiency because additional time and manpower are required to adjust the position of the blank or to deal with the problem parts. Utility Model Content

[0005] The purpose of the present invention is to overcome the above technical deficiencies and to propose a centering tapper to solve the technical problem in the prior art that the centering fingers of the centering tapper cannot adjust their positions, resulting in the tapping position of some sheets being at the notch and the sheets being unable to be centered.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] In order to solve the technical problem that the centering fingers of the existing centering flapper cannot adjust their positions, resulting in the flapping position of some sheets being at the notch and the sheet being unable to be centered, the utility model provides a centering flapper, which can insert an insertion rod (commonly known as centering fingers) into one or several mounting holes according to the actual situation of the sheet, so that when the centering flapper flaps the sheet, the insertion rod contacts the appropriate position of the sheet, so that the sheet can obtain a good centering effect.

[0024] It should be noted that the centering beater described in the present invention is used for but not limited to a punching machine. For the sake of convenience, in the present invention, only the application of the centering beater to a punching machine is used as an example for explanation. The principle of applying the centering beater to other equipment that requires centering of the sheet is essentially the same as the principle applied to the centering beater, and will not be described in detail here.

[0025] See also Figure 1 and Figure 2 , Figure 1 This is a structural diagram of a centering beater in one embodiment of the present invention. Figure 2 The centering beater includes a fixing base 1, an inserting rod 2 and a driving pendulum block 3.

[0026] The fixing base 1 has multiple mounting holes 11, with multiple mounting holes 22 arranged along the direction of the material's travel. One end of the insertion rod 2 is detachably connected to the mounting hole 11, and the other end of the insertion rod 2 extends outside the mounting hole 11 to push the material. A driving pendulum 3 is fixedly connected to the fixing base 1 and is designed to connect to an external drive mechanism to drive the movement of the insertion rod 2.

[0027] During use, the two centering beaters form a pair, symmetrically positioned on either side of the blank. Mounting holes 22 are arranged along the blank's travel direction. The two drive mechanisms, through the drive pendulum blocks 3, drive the two plungers 2 synchronously toward the blank. The plungers 2 push the blank to the center position, ensuring it meets the requirements of the stamping process.

[0028] In this embodiment, in some embodiments, the mounting hole 11 of the fixing base 1 is located on the upper surface of the fixing base 1 , the lower end of the insertion rod 2 is detachably connected to the mounting hole 11 , and the upper part of the insertion rod 2 is used to push the sheet.

[0029] In some embodiments, the mounting base 1 is formed with at least one pair of connecting protrusions 12, located on either side of the mounting holes 11. Through these connecting protrusions 12, the centering flapper can be attached to other fixed structures or drive mechanisms, functioning similarly to the drive pendulum 3. These connecting protrusions 12 can enrich the centering flapper's connection options to meet diverse production needs.

[0030] In this embodiment, the insertion rod 2 comprises a rod body 21, a spring, and a push block 22. A through hole is formed at the bottom of the rod body 21, with both ends communicating with the side surfaces of the rod body 21. A spring is housed within the through hole, and its ends are fixedly connected to two push blocks 22. When the insertion rod 2 is inserted into the mounting hole 11, the spring is compressed, generating a force that forces the push blocks 22 to press against the inner wall of the mounting hole 11. This ensures that the insertion rod 2 is firmly inserted into the mounting hole 11 and prevents it from loosening during centering.

[0031] In some embodiments, a groove corresponding to the top block is formed on the inner wall of the mounting hole 11 , and the top block 22 is partially embedded in the groove to enhance the firmness of the connection between the insertion rod 2 and the mounting hole 11 .

[0032] In a preferred embodiment, the top block 22 is spherical, and the recess is a corresponding curved groove. This curved surface fit reduces the difficulty of removing the insertion rod 2 and facilitates the operator to adjust the position of the insertion rod 2. This achieves a balance between a secure connection and easy adjustment.

[0033] In this embodiment, the rod body 21 includes a fixedly connected plug portion and a centering portion, that is, the lower half of the rod body 21 is the plug portion, and the upper half is the centering portion. The through hole is located on the plug portion, and the axis of the plug portion and the axis of the centering portion are arranged to coincide.

[0034] In other embodiments, the axes of the plug-in portion and the centering portion can also be staggered, that is, the rod body 21 has a bent structure. Even with multiple spaced mounting holes 11, there is still the possibility that all mounting holes 11 are not suitable. By using a bent insertion rod 2, after the plug-in portion is inserted into the mounting hole 11, the centering portion 11 is located between the two mounting holes 11, thereby meeting the centering requirements of the sheet and further expanding the applicability of the centering flapper.

[0035] In some embodiments, the driving pendulum block 3 has a connection hole 31 for connecting to a driving mechanism. The driving mechanism usually adopts a driving device such as a cylinder or a motor, which drives the centering beater to move by connecting to the connection hole 31.

[0036] In some embodiments, the centering beater further includes a base 4, which is fixedly connected to the driving pendulum block 3, and the fixing seat 1 is detachably connected to the base 4. Through the base 4, fixing seats 1 of different sizes and shapes can be installed on the driving pendulum block 3.

[0037] In this embodiment, the base 4 has a pair of first connection holes 41 and a pair of second connection holes 42. These holes are symmetrically arranged about the axis of the base 4, ensuring a more balanced force during connection. The first connection holes 41 are used to connect to the fixing base 1, while the second connection holes 42 are used to connect to the driving pendulum mass 3. Mounting holes are provided on the fixing base 1 and the driving pendulum mass 3, respectively. The connection can be made using either a latch or screws.

[0038] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
