Description

Technical Field

[0001] This utility model relates to the field of headphone headband technology, specifically to a stamping mechanism for headphone headbands. Background Technology

[0002] The headband is a curved, elastic piece on over-ear headphones, serving as the framework for the various headphone components. Steel headbands typically have a curved structure to fit the contours of the human head and include various slots and other structures for connecting headphone components.

[0003] Existing headphone headband processing equipment stamps raw materials into the required parts. In the headband processing process, the rolled workpiece is first fed into the stamping equipment using a feeding device, and then stamped using the stamping equipment. During the operation, the workpiece is prone to bending and deformation during feeding, which can easily cause it to get stuck in the stamping equipment during stamping. Therefore, it is not possible to accurately fix the workpiece, which affects the production quality. Therefore, a headphone headband stamping mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a stamping mechanism for an earphone headband, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stamping mechanism for an earphone headband, including a worktable, on which a stamping mechanism and a fixing mechanism are respectively arranged;

[0006] The stamping mechanism includes: a frame, which is fixedly connected to the top rear of the workbench. The frame is arranged in an inverted "L" shape. A stamping cylinder is connected to the inner top of the frame. A mounting plate is fixedly connected to the piston end of the stamping cylinder. A stamping head is connected to the bottom of the mounting plate.

[0007] The fixing mechanism includes a fixing plate and a triangular plate. The fixing plate is fixedly connected to the top of the workbench. A slide rod is slidably connected to the right side of the fixing plate. A roller is connected to the right end of the slide rod. The left end of the slide rod passes through the fixing plate and extends to the left. A wedge block is fixedly connected to the extended end of the slide rod, and the bottom of the wedge block is in contact with the top of the workbench. A fixing ring is fixedly sleeved on the outer wall of the slide rod. A spring is fixedly connected to the left side of the fixing ring, and the left end of the spring is fixedly connected to the right side of the fixing plate. The triangular plate is fixedly connected to the bottom of the mounting plate.

[0008] Preferably, the top of the workbench is provided with a stamping groove, and the bottom of the stamping groove is provided with a stamping hole that is compatible with the stamping head.

[0009] Preferably, the top of the workbench has a movable hole, which is located directly below the triangular plate.

[0010] Preferably, there are two sets of fixing mechanisms, which are arranged opposite to each other on the top of the workbench.

[0011] Preferably, the worktable is provided with a demolding mechanism, which includes: a second spring, the second spring being fixedly connected to the bottom of the worktable, a connecting plate being fixedly connected to the bottom end of the second spring, a pressure rod being fixedly connected to the top rear of the connecting plate, the top end of the pressure rod penetrating the worktable and extending upward, and a top rod being fixedly connected to the top front of the connecting plate, the top end of the top rod penetrating the stamping groove and extending upward.

[0012] Preferably, the top of the workbench has a sliding hole, the pressure rod is slidably connected to the sliding hole, the bottom of the stamping groove has a sliding hole, and the top rod is slidably connected in the sliding hole.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. The stamping mechanism for an earphone headband uses a mounting plate that descends to move a triangular plate. The inclined surface of the triangular plate pushes a roller, causing the roller to slide horizontally along a sliding rod. This causes the sliding rod to move a wedge block, which in turn moves a fixing ring to compress a spring. This causes the two wedge blocks to slide relative to each other and press the workpiece into the stamping groove, keeping the bent workpiece straight and facilitating the pressing and fixing of the workpiece. This improves stamping quality.

[0015] 2. The stamping mechanism for an earphone headband moves a pressing rod via a mounting plate. The pressing rod causes a connecting plate to descend and stretches a spring, which in turn causes a top rod to descend via the connecting plate. When the stamping is finished and the mounting plate rises, the spring itself causes the connecting plate to rise. The connecting plate then causes the pressing rod and the top rod to rise, which in turn pushes the workpiece out of the stamping groove, facilitating workpiece unloading and improving production efficiency.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0025] Please see Figure 1-4One embodiment of this utility model is: a stamping mechanism for an earphone headband, including a workbench 1, with support legs fixedly connected to the four corners of the bottom of the workbench 1, and a stamping mechanism 2 and a fixing mechanism 3 respectively arranged on the workbench 1; the stamping mechanism 2 includes: a frame 21, which is fixedly connected to the top rear of the workbench 1, and the frame 21 is arranged in an inverted "L" shape. A stamping cylinder 22 is connected to the inner side of the top of the frame 21, and a mounting plate 23 is fixedly connected to the piston end of the stamping cylinder 22. The bottom of the mounting plate 23 is... A punch head 24 is connected to the worktable 1. A punching groove is provided on the top of the worktable 1, and a punching hole adapted to the punch head 24 is provided at the bottom of the punching groove. The fixing mechanism 3 includes a fixing plate 31 and a triangular plate 37. The fixing plate 31 is fixedly connected to the top of the worktable 1. A slide rod 32 is slidably connected to the right side of the fixing plate 31. A roller 33 is connected to the right end of the slide rod 32. The left end of the slide rod 32 passes through the fixing plate 31 and extends to the left. A wedge block 34 is fixedly connected to the extended end of the slide rod 32, and the bottom of the wedge block 34 is flush with the worktable. The top of the worktable 1 is fitted together, and a fixing ring 35 is fixedly sleeved on the outer wall of the slide rod 32. A spring 36 is fixedly connected to the left side of the fixing ring 35, and the left end of the spring 36 is fixedly connected to the right side of the fixing plate 31. The triangular plate 37 is fixedly connected to the bottom of the mounting plate 23. A moving hole 38 is opened on the top of the worktable 1 and is located directly below the triangular plate 37. The moving hole 38 facilitates the up and down movement of the triangular plate 37 and avoids collision between the triangular plate 37 and the worktable 1. There are two sets of fixing mechanisms 3. Two sets of fixing mechanisms 3 are set opposite to each other on the top of the workbench 1. The mounting plate 23 descends and drives the triangular plate 37 to move. The inclined surface of the triangular plate 37 pushes the roller 33, thereby causing the roller 33 to drive the slide rod 32 to slide horizontally. This causes the slide rod 32 to drive the wedge block 34 to move, and at the same time, it drives the fixing ring 35 to move and compress the spring 36. This causes the two wedge blocks 34 to slide relative to each other and press the workpiece into the stamping groove, keeping the bent workpiece straight and making it easy to press and fix the workpiece, which is convenient for stamping and forming and improves the production quality.

[0026] Working principle: The workpiece is placed in the stamping groove with the bent part facing upwards. The stamping cylinder 22 drives the mounting plate 23 to descend. The descent of the mounting plate 23 moves the triangular plate 37. The inclined surface of the triangular plate 37 pushes the roller 33, causing the roller 33 to drive the sliding rod 32 to slide horizontally. This causes the sliding rod 32 to move the wedge block 34, which in turn moves the fixing ring 35 to compress the spring 36. This causes the two wedge blocks 34 to slide relative to each other and press the workpiece into the stamping groove, keeping the bent workpiece straight and facilitating the clamping and fixing of the workpiece. At the same time, the movement of the mounting plate 23 drives the stamping head 24 to descend and perform stamping operations on the fixed workpiece. After stamping, the stamping cylinder 22 drives the mounting plate 23 to rise, and the triangular plate 37 disengages from the roller 33. Under the elastic force of the spring 36, the wedge block 34 returns to its original position, thus releasing the clamping and fixing of the workpiece.

[0027] Please see Figure 1-4 Based on the above embodiments, in another embodiment of this utility model, a demolding mechanism 4 is provided on the workbench 1. The demolding mechanism 4 includes: a second spring 41, which is fixedly connected to the bottom of the workbench 1. A connecting plate 42 is fixedly connected to the bottom end of the second spring 41. A pressure rod 43 is fixedly connected to the rear of the top of the connecting plate 42. The top end of the pressure rod 43 passes through the workbench 1 and extends upward. A push rod 44 is fixedly connected to the front of the top of the connecting plate 42. The top end of the push rod 44 passes through the stamping groove and extends upward. A sliding hole is provided on the top of the workbench 1. The pressure rod 43 is slidably connected to the sliding hole. The bottom of the stamping groove has a sliding hole, and the push rod 44 is slidably connected in the sliding hole. The pressure rod 43 is moved down by the mounting plate 23. The pressure rod 43 drives the connecting plate 42 to descend and stretches the second spring 41, thereby causing the connecting plate 42 to drive the push rod 44 to descend. When the stamping is finished and the mounting plate 23 rises, the second spring 41 drives the connecting plate 42 to rise through its own elastic force. The connecting plate 42 drives the pressure rod 43 and the push rod 44 to rise, thereby causing the push rod 44 to push the workpiece out of the stamping groove, which facilitates the unloading of the workpiece and improves production efficiency.

[0028] Working principle: The mounting plate 23 moves the pressure rod 43, which drives the connecting plate 42 to descend and stretches the spring 41. This causes the connecting plate 42 to drive the push rod 44 to descend. When the stamping is finished and the mounting plate 23 rises, the spring 41 itself drives the connecting plate 42 to rise. The connecting plate 42 drives the pressure rod 43 and the push rod 44 to rise, which in turn pushes the push rod 44 out of the stamping groove, making it easier for the workpiece to be unloaded.

[0029] It is worth noting that the stamping cylinder 22 and stamping head 24 in the above embodiments are common equipment in the prior art. The models used can be customized according to actual usage requirements. In addition, the power supply interface of the electrical equipment in this utility model is connected to the power supply system through a switch (not shown in the figure) and a wire (not shown in the figure) to realize its control.
