Description

Technical Field

[0001] This utility model relates to the field of stamping and panel separation technology, specifically a low-noise, high-precision stamping and panel separation mold. Background Technology

[0002] In many industries such as electronics manufacturing and machining, it is often necessary to perform sheet metal separation operations, that is, to divide a large sheet metal into multiple smaller pieces of the required size. Stamping separation dies are a commonly used separation tool. Through the cooperation of upper and lower dies, stamping pressure is used to divide the sheet metal into predetermined shapes.

[0003] In traditional stamping die-cutting processes, the upper and lower dies typically employ direct stamping, lacking effective buffering and noise reduction structures between the stamped and pressure-bearing parts. Due to the significant impact force and lack of cushioning during stamping, the direct stamping causes violent collisions between die components, generating substantial noise. This noise accumulates, creating severe noise pollution. Prolonged exposure to high-noise environments not only affects the hearing health of operators but also hinders communication among them, thus reducing work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a low-noise, high-precision stamping die for separating panels. The noise reduction structure can reduce the noise during the stamping process, avoid noise pollution, ensure the hearing health of operators and smooth communication between operators, and ensure work efficiency.

[0005] The above-mentioned optimized structure of this utility model is achieved through the following technical solution: a low-noise, high-precision stamping and separating mold, including a fixed base; A drive assembly is disposed on top of the fixed base; Two stamped parts are symmetrically arranged at the bottom of the drive assembly; Three fixed vertical plates are evenly spaced at the bottom of the fixed base; Two pressure-bearing components, each with a plate to be stamped, are positioned below the stamping component and between two adjacent fixed vertical plates. A noise reduction structure is provided between the pressure-bearing member, the bottom of the fixed base, and the bottom of the drive assembly.

[0006] In some embodiments, the noise reduction structure includes two end plates, and three fixed vertical plates are provided between the two end plates; A sliding assembly, wherein the sliding assembly is disposed between one end face of the pressure-bearing member and the end plate; A noise-reducing spring is disposed between the bottom of one end of the pressure-bearing member and the fixed base.

A limiting block is provided at one end of the pressure-bearing member near the end plate and can slide along the height direction within the limiting groove.

[0010] In some embodiments, an adjustment component is further included, the adjustment component including an adjustment screw that is screwed into the bottom of the drive component; A stop pin is coaxially located at the bottom of the adjusting screw and can be attached to the pressure-bearing component.

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] refer to Figure 1-3A low-noise, high-precision stamping and separating die includes a fixed base 1, a drive assembly 2, two stamping parts 3, three fixed vertical plates 4, two pressure-bearing parts 5, and a noise reduction structure 6. The fixed base 1 is the basic support structure of the entire die, providing installation positions and stable support for other components. The fixed base 1 can be made of high-strength alloy steel, capable of withstanding the large loads generated during the die's operation, providing stable support for the entire die. The shape of the fixed base 1 can be designed according to actual needs. The drive assembly 2 is located at the top of the fixed base 1 and serves as the power source for the die, driving the stamping parts 3 to perform stamping actions. The two stamping parts 3 are symmetrically arranged at the bottom of the drive assembly 2 and can cooperate with the pressure-bearing parts 5 to fix the plate to be stamped during the stamping process. The three fixed vertical plates 4 are equally spaced at the bottom of the fixed base 1. The pressure-bearing parts 5 are equipped with the plate to be stamped and are correspondingly located below the stamping parts 3 and between two adjacent fixed vertical plates 4. The top surface of the pressure-bearing parts 5 has a placement groove for placing the plate to be stamped. The size and shape of the stamping plate and the placement groove are designed according to the specifications of the plate to be stamped, ensuring that the plate to be stamped can be accurately placed on the bearing component 5. The stamping component 3 is driven by the drive assembly 2 to stamp the plate to be stamped on the bearing component 5. With the cooperation of the fixed vertical plate 4, the long sides of the plate to be stamped are separated, realizing the separation of the plate to be stamped. The distance between the fixed vertical plate 4 and the bearing component 5 can be set according to parameters such as the width of the long side to be separated of the plate to be stamped, to ensure the smooth separation of the plate to be stamped. This is existing technology and will not be described in detail here. The noise reduction structure 6 is located between the bearing component 5 and the bottom of the fixed seat 1 and the bottom of the drive assembly 2. It can reduce the noise generated during the stamping process, avoid noise pollution, ensure the hearing health of the operators and smooth communication between operators, and ensure work efficiency. At the same time, it can reduce the direct impact force on the plate to be stamped and protect the components on the plate to be stamped.

[0018] In some embodiments, the noise reduction structure 6 includes two end plates 61, a sliding assembly 62, and a noise reduction spring 63. Three fixed vertical plates 4 are provided between the two end plates 61 and are fixedly connected to the fixed base 1. These plates can be welded together to provide a mounting base for other noise reduction components. The sliding assembly 62 is located between one end face of the pressure-bearing member 5 and the end plates 61, enabling the pressure-bearing member 5 to move up and down between the two end plates 61. The noise reduction spring 63 is located between the bottom of one end of the pressure-bearing member 5 and the fixed base 1. During the stamping process, the noise reduction spring 63 deforms, absorbing some of the impact force and reducing the impact of the plate to be stamped on the fixed vertical plates 4, thereby reducing the intensity of vibration and collision and decreasing noise generation. Simultaneously, the noise reduction spring 63 allows the pressure-bearing member 5 to quickly return to its initial position after stamping, ensuring the continuous working performance of the mold.

[0019] In some embodiments, the noise reduction structure 6 further includes a buffer 64, which may be a buffer pressure telescopic rod. The buffer 64 is fixed to the bottom of the drive assembly 2, and the telescopic end of the buffer 64 can be attached to the pressure bearing 5. When the stamping part 3 is about to contact the pressure bearing 5, the buffer 64 contacts the pressure bearing 5 first, playing a preliminary buffering role and reducing the impact force. The principle is the same as that of the noise reduction spring 63, which can reduce the noise generated when the stamping part 3 contacts the pressure bearing 5 and protect the components on the stamping plate from being crushed.

[0020] In some embodiments, the sliding assembly 62 includes a slide rail 621 and a slider 622. The slide rail 621 is vertically disposed on the end plate 61 near the noise-reducing spring 63 and can be fixed by bolts. The slider 622 is disposed on the side of the pressure-bearing member 5 near the slide rail 621 and can be fixed by bolts. The cross-section of the slide rail 621 can be dovetail groove shaped and can be slidably disposed on the slide rail 621. Through the cooperation of the slide rail 621 and the slider 622, the pressure-bearing member 5 can move smoothly up and down along the slide rail 621 when subjected to impact force, reducing friction and collision between components and further reducing noise.

[0021] In some embodiments, the noise reduction structure 6 further includes a limiting groove 65 and a limiting block 66. The limiting groove 65 is located on the end plate 61 near the noise reduction spring 63, and the limiting block 66 is located on the end of the pressure-bearing member 5 near the end plate 61, and can slide along the height direction within the limiting groove 65. The cooperation of the limiting groove 65 and the limiting block 66 can limit the movement range of the pressure-bearing member 5, prevent it from undergoing excessive displacement during the stamping process, and ensure the accuracy and stability of the stamping.

[0022] In some embodiments, an adjustment component 7 is also included. The adjustment component 7 includes an adjustment screw 71 and a stop pin 72. The adjustment screw 71 can be screwed into the bottom of the lifting platform 22. By rotating the adjustment screw 71, its relative position to the bottom of the lifting platform 22 can be adjusted. The stop pin 72 is coaxially disposed at the bottom of the adjustment screw 71, can be welded and fixed, and can be attached to the pressure-bearing member 5. By adjusting the adjustment screw 71, the distance between the stop pin 72 and the pressure-bearing member 5 can be changed, thereby adjusting the stamping depth of the stamping part 3, and further adjusting the gap between the stamping part 3 and the plate to be stamped, meeting the requirements for separating different plates, and improving the versatility and flexibility of the mold.

[0023] In some embodiments, the drive assembly 2 includes a cylinder 21, a lifting platform 22, four limiting rods 23, and four limiting sleeves 24. The cylinder 21 is located on the top of the fixed base 1 and provides power for the lifting platform 22 to move up and down. The lifting platform 22 is connected to the output shaft of the cylinder 21 and can be fixed with bolts. The bottom of the lifting platform 22 is provided with two stamping parts 3. The lifting platform 22 can be made of aluminum alloy. The four limiting rods 23 are located on the lifting platform 22, and the four limiting sleeves 24 are located on the top of the fixed base 1. The limiting sleeves 24 pass through and slide with the limiting rods 23. Through the cooperation of the limiting rods 23 and the limiting sleeves 24, the stability of the lifting platform 22 during the up and down movement is ensured, preventing it from deviating, thereby improving the stamping accuracy.

[0024] In some embodiments, the stamping part 3 may be a channel plate, which can be pressed onto the plate to be stamped by pressing the two sides of the channel plate and forming a clearance space between the two sides. This allows the plate to be fixed when the stamping part 3 and the pressure bearing part 5 are engaged, while preventing the stamping part 3 from contacting the components on the plate to be stamped, thereby protecting the components on the plate to be stamped.

[0025] The specific working principle is as follows: In practical use, the plate to be stamped is placed on the corresponding position of the stamping part 3, ensuring its stable placement on the stamping part 3. This is existing technology and will not be elaborated further. After placement, the cylinder 21 drives the lifting platform 22 downward. During this process, the limiting rod 23 slides and guides within the limiting sleeve 24, ensuring the vertical descent of the stamping part 3. Before the stamping part 3 contacts the plate to be stamped, the telescopic end of the buffer 64 first adheres to the top surface of the pressure bearing 5, absorbing part of the impact force. Subsequently, the stamping part 3 presses onto the plate to be stamped, causing the pressure bearing 5 and the plate to be stamped to descend together. The noise reduction spring 63 is compressed and deformed, converting the remaining impact force into elastic potential energy. When the two sides of the plate to be stamped contact the two fixed vertical plates 4 respectively, the stamping part 3 exerts a downward force on the plate to be stamped, and the fixed vertical plates 4 exert an upward force on the plate to be stamped. Under the action of the two opposing forces, the side plates of the plate to be stamped are separated. After a certain stroke, the cylinder 21 moves in the opposite direction, causing the stamping part 3 to rise. At this time, the noise reduction spring 63 resets, causing the pressure bearing 5 and the plate to be pressed to rise, and the plate to be pressed after separation is taken out, thus completing the separation of the plate to be pressed.
