Description

Technical Field

[0001] This application relates to the field of stamping equipment technology, and in particular to a multi-head stamping mechanism. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces of the desired shape and size. Common stamping mechanisms can be divided into crank-connecting rod mechanisms, screw mechanisms, and hydraulic mechanisms, etc.

[0003] In related technologies, a punch press is disclosed, including a frame, a worktable mounted on the frame, and a stamping device mounted above the worktable. The output end of the stamping device is equipped with a punch for stamping workpieces, and the worktable is provided with a clamping mechanism for holding workpieces, so as to cooperate with the punch to perform stamping processing on the workpieces.

[0004] Regarding the aforementioned technologies, during the stamping process of workpieces, different stamping steps usually require the replacement of punches of different specifications. The process of replacing punches is very cumbersome, which seriously affects the stamping efficiency of workpieces and therefore needs to be improved. Utility Model Content

[0005] To address the issue of cumbersome punch changing processes affecting workpiece stamping efficiency, this application provides a multi-head stamping mechanism.

[0006] The multi-head stamping mechanism provided in this application adopts the following technical solution:

[0007] A multi-head stamping mechanism includes a machine body and a processing table mounted on the machine body. A stamping part for stamping workpieces is provided on the side wall of the machine body facing the processing table. A mounting base is provided at the output end of the stamping part. A rotating seat is rotatably mounted on the mounting base. A plurality of punches for stamping workpieces are provided on the side wall of the rotating seat facing the processing table, and all the punches are distributed at intervals along the circumference of the rotating seat. A driving assembly is provided on the mounting base to drive the rotating seat to rotate the punches.

[0008] By adopting the above technical solution, the drive component drives the rotating seat to rotate the punch around the mounting base, so as to quickly change different types of punches to face the processing table. This facilitates the stamping of workpieces on the processing table in conjunction with the stamping parts and the mounting base, realizing the rapid change of punches to achieve different types of stamping operations and improving the stamping efficiency of workpieces.

[0009] Preferably, the drive assembly includes a drive support, a drive motor, a drive gear, and a transmission gear ring; the drive support is disposed on a mounting base, the drive motor is disposed on the drive support, and the drive gear is disposed at the output end of the drive motor; the transmission gear ring is disposed on the side wall of the rotating base facing the drive gear, and the transmission gear ring meshes with the drive gear.

[0010] By adopting the above technical solution, the drive support facilitates the fixed installation of the drive motor on the mounting base. The output end of the drive motor drives the drive gear, which meshes with the transmission gear ring to rotate, thereby driving the rotating base to drive the punch to rotate around the mounting base.

[0011] Preferably, the side wall of the rotating seat facing the transmission gear ring is provided with an extension ring sleeve around the transmission gear ring, and the extension ring sleeve is provided with a protective ring plate for covering the transmission gear ring away from the side wall of the rotating seat.

[0012] By adopting the above technical solution, the extension ring and the protective ring cover and protect the transmission gear ring and the drive gear, ensuring the service life of the drive assembly; at the same time, the protective ring plate fits against the side wall of the mounting base away from the rotating base to prevent the mounting base and the rotating base from separating from each other.

[0013] Preferably, the mounting base has a through mounting notch for the drive gear to abut.

[0014] By adopting the above technical solution, the drive gear is inserted into the mounting notch, reducing the space occupied by the drive assembly after it is combined with the mounting base, and further reducing the space occupied by the overall structure.

[0015] Preferably, the rotary seat is inclined at the end of the mounting base facing the processing table, and the axial direction of the punch to be worked on the rotary seat is coaxial with the central axis of the mounting base.

[0016] By adopting the above technical solution, the tilted rotating seat makes the axis of the punch to be worked on the rotating seat work position coaxial with the axis of the mounting seat, and makes the axis of the punch coaxial with the axis of the output end of the stamping part. This makes the stamping force of the stamping part more concentrated on the punch, and makes the rotating seat and the punch to be worked more concentrated in force, reducing the loss of the impact force of the stamping part, and ensuring the working effect of the rotating seat and the punch.

[0017] Preferably, each punch has a fixing ring plate on its peripheral wall, and a number of fixing bolts threaded through the fixing ring plate are threaded to the rotating seat; each punch has a threaded head on its side wall facing the rotating seat, and a number of threaded holes are provided on the rotating seat for threaded connection of the threaded head.

[0018] By adopting the above technical solution, the fixing ring plate and the fixing bolt cooperate with each other to fix the punch to the rotating seat, so as to facilitate the replacement of the punch on the rotating seat and further improve the convenience of punch replacement; the threaded connection between the threaded head and the rotating seat further improves the connection stability between the punch and the rotating seat.

[0019] Preferably, the mounting base has a mounting groove on the side wall facing the rotating base, the mounting groove is provided with a projectile for making a sound, and the mounting groove is provided with an elastic element for driving the projectile to impact the rotating base; the rotating base has a number of positioning grooves on the side wall facing the mounting base for the projectile to enter, and the positioning grooves are respectively provided with each set of punches.

[0020] By adopting the above technical solution, during the process of the drive component driving the rotating seat to rotate, when the mounting slot is aligned with a certain positioning slot, the elastic element drives the projectile to abut into the positioning slot and make a sound to remind the user that the punch to be worked is in the aligned state. That is, at this time, the central axis of the punch is coaxial with the axis of the mounting seat, which makes it easy to accurately adjust the position of the punch.

[0021] Preferably, a rotary table is rotatably mounted on the processing table, and a rotating component for driving the rotary table to rotate is provided inside the processing table. Several sets of bases for clamping workpieces are arranged at intervals along the circumference of the rotary table on the rotary table.

[0022] By adopting the above technical solution, the rotating component drives the rotary table to rotate the base, which, in conjunction with the machine body, achieves the goal of changing the base without changing it or changing it synchronously during the punch replacement process, thus enabling the adjustment of workpieces in a larger stamping process.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a drive component to drive the rotating seat to rotate the punch around the mounting base, different types of punches can be quickly switched to face the processing table. This facilitates the stamping of workpieces on the processing table in conjunction with the stamping parts and the mounting base, realizing the ability to quickly change punches to achieve different types of stamping operations and improving the stamping efficiency of workpieces.

[0025] 2. During the rotation of the rotating seat by the drive component, the elastic element drives the projectile to abut into the positioning groove and make a sound to remind the user that the punch to be worked is in the correct position, so as to facilitate accurate adjustment of the position of the punch.
