Description

Technical Field

[0001] This utility model relates to the technical field of punch press dust cleaning mechanisms, specifically a punch press dust cleaning and protection mechanism. Background Technology

[0002] During operation, punch presses generate dust. This dust settles on the workpiece and die, negatively impacting workpiece forming and subsequent processing, including surface damage. Current dust removal methods involve manual cleaning such as blowing dust with an air gun or sweeping with a feather duster.

[0003] When dust is removed by air gun or manual sweeping, on the one hand, the dust will spread everywhere and cause air pollution; on the other hand, dust is easy to remain in the dead corners of the mold and workpiece. Moreover, during the pressing process, under the influence of air humidity and oil stains on the mold surface, old dust will stick together under high pressure, forming agglomerated dust that is difficult to completely remove by airflow impact or manual sweeping. At the same time, manual removal will also affect production efficiency.

[0004] In view of this, we propose a dust cleaning and protection mechanism for punch presses. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-7 A dust cleaning and protection mechanism for a punch press includes a lower frame 1 and an upper frame 4. A worktable 2 is fixedly installed at the top of the lower frame 1, and a mold 3 is detachably installed on the worktable 2. The mold 3 can be replaced according to different stamping requirements, thereby adapting to different stamping workpieces and stamping needs. A pressing table 5 is provided inside the upper frame 4. The pressing table 5, in conjunction with the mold 3, can stamp and form the workpiece.

[0019] Please see Figures 1-4 The lower frame 1 is equipped with a dust collection mechanism 6, which is used to blow away the dust on the lower frame 1 and the workpiece with an electrostatic airflow, blowing up the dust generated during the stamping process and making the dust particles charged, and then collecting the blown dust by electrostatic adsorption.

[0020] Please see Figure 2 The dust collection mechanism 6 includes a corrugated blower 62, which is connected to an electrostatic generator 61 via a pipe. The electrostatic generator 61 is then connected to an air pump via another pipe. When the air pump is working, gas is blown out through the corrugated blower 62 via the pipe, thereby sweeping away the dust. At the same time, the electrostatic generator 61 charges the passing gas, thus charging the dust particles when the gas blows away the dust.

[0021] It should be noted that the corrugated blower 62 adopts a corrugated pipe structure, and its corrugated part is truncated cone-shaped, which allows the operator to manually adjust the direction of the corrugated blower 62 to adapt to the dust removal needs of different workpieces.

[0022] Please see Figure 3There are multiple corrugated blowers 62 arranged in an array, allowing for a larger blowing area when blowing the mold 3 and workpiece. The blowing direction of each blower 62 can be independently adjusted, enabling adjustable blowing area and position during operation, thus improving the adaptability of the blowing process. Furthermore, a blower pipe 63 is detachably connected to the air outlet of each of the corrugated blowers 62. Detachment methods include, but are not limited to, snap-fit ​​and magnetic connections. The blower pipe 63 is a flat pipe, narrower at the front and wider at the back. When multiple independent airflows pass through, the change in the pipe's cross-section compresses and guides the airflow. This makes the airflow velocity more uniform and stable at the outlet, achieving a "uniform airflow" effect. Simultaneously, it efficiently integrates and guides the potentially interfering point-like airflows into a wide, unified, and evenly distributed planar air curtain. The blowing pipe 63 can effectively prevent the disorderly diffusion of dust caused by uneven local airflow intensity or scattered direction, thereby improving the uniformity of blowing and effectively suppressing the phenomenon of dust escaping the collection area due to rapid dispersion during the processing.

[0023] Please see Figure 4 An electrostatic adsorption plate 64 is fixedly installed on the lower frame 1. The electrostatic adsorption plate 64 is arranged opposite to the corrugated blower head 62, and the electrostatic adsorption plate 64 carries an electrode. This electrode is opposite to the electrode generated by the electrostatic generator 61, so that the electrostatic adsorption plate 64 can attract charged dust and adsorb the dust onto the electrostatic adsorption plate 64, thereby completing the collection and capture of dust and avoiding dust re-entrainment.

[0024] In this embodiment, a collection box 65 is fixedly installed at the bottom of the electrostatic adsorption plate 64. The collection box 65 is used to collect dust for convenient subsequent unified processing. A negative pressure port 66 is opened at the top of the collection box 65. The collection box 65 is connected to an air pump. The air pump can generate negative pressure at the negative pressure port 66, thereby assisting the collection box 65 in collecting dust and preventing dust from escaping when transferring from the electrostatic adsorption plate 64 to the collection box 65.

[0025] It is important to note that a grounded conductive rope is fixedly installed on the electrostatic adsorption plate 64. Its function is to quickly conduct the residual static charge on the electrostatic adsorption plate 64 to the ground after each operation, thereby effectively eliminating the risk of spark discharge that may be caused by charge accumulation. At the same time, the negative pressure inside the collection box 65 is continuously maintained to ensure that the collected dust is always in a controlled settling state, preventing the dust from floating in the collection box 65 and forming a high-concentration dust cloud with an explosion risk, thus enhancing safety.

[0026] Please see Figures 5-7 The upper frame 4 is equipped with a self-cleaning mechanism 7. When the pressing table 5 is pressed down, the self-cleaning mechanism 7 can sweep away the dust on the surface of the electrostatic adsorption plate 64, so that the dust enters the collection box 65 and is collected.

[0027] Please see Figure 5 The self-cleaning mechanism 7 includes a fixed pulley 71, which is rotatably mounted on the upper frame 4. A steel cable 73 is mounted on the fixed pulley 71, with one end of the cable 73 fixedly mounted on the pressing table 5 and the other end fixedly mounted on a driven block 72. The combination of the fixed pulley 71 and the steel cable 73 allows the driven block 72 to move synchronously when the pressing table 5 moves, and the displacement distances are consistent. Furthermore, a limit groove 74 is formed on the surface of the upper frame 4, within which the driven block 72 is slidably mounted. The limit groove 74 is a straight groove, which limits the movement of the driven block 72, ensuring that the driven block 72 can only move along the direction of the limit groove 74.

[0028] Please see Figure 6 and Figure 7 A rotating seat 77 is fixedly mounted on the surface of the upper frame 4. A rotating rod 76 with unequal lengths at both ends is rotatably mounted on the rotating seat 77. The rotating rod 76 and the rotating seat 77 together form a lever structure. The short arm end of the rotating rod 76 is slidably connected to the driven block 72, and the long arm end is slidably connected to the cleaning strip 75. When the driven block 72 at the short arm end is displaced, the lever action amplifies and transmits the displacement to the long arm end, making the displacement distance of the cleaning strip 75 N times that of the driven block 72. This amplification factor N is directly determined by the length ratio of the long arm to the short arm.

[0029] In this embodiment, a limiting rod 78 is fixedly installed between the upper frame 4 and the collection box 65, and the cleaning strip 75 is slidably connected to the limiting rod 78. The limiting rod 78 serves to limit the movement of the cleaning strip 75, ensuring that it can only move along the limiting rod 78. This ensures that the cleaning strip 75 remains in contact with the surface of the electrostatic adsorption plate 64 during its movement, thus cleaning the electrostatic adsorption plate 64. It should be noted that the rotating rod 76 is slidably connected to the driven block 72 and the cleaning strip 75 respectively, so that when the rotating rod 76 transmits displacement, it will not cause motion interference to the driven block 72 and the cleaning strip 75. The driven block 72 has a large mass, and the driven block 72 is elastically connected to the top of the limiting groove 74 through a spring, so that when the pressing table 5 moves upward, the driven block 72 can drive the entire self-cleaning mechanism 7 to reset through its own weight and the restoring force of the spring.

[0030] In addition, the cleaning strip 75 is made of an elastic conductive material, such as conductive rubber, and a grounding rope is fixedly installed on the cleaning strip 75 to prevent static electricity from causing fire due to friction when it comes into contact with the electrostatic adsorption plate 64, and at the same time, it can help to discharge static electricity.

[0031] A dust removal and protection mechanism for punch presses, the working principle of which is as follows: By adjusting the corrugated blower head 62, the blower pipe 63 and the corrugated blower head 62 can be aligned with the dust generation area of ​​the workpiece and the mold 3.

[0032] When the pressing is finished, the air pump and electrostatic generator 61 are started, so that the blower pipe 63 and the corrugated blower head 62 generate charged airflow to blow away the workpiece and mold 3, thereby blowing away the dust generated during pressing and charging the dust particles. The dust blown up is displaced towards the electrostatic adsorption plate 64 by the wind force and the adsorption force of the electrostatic adsorption plate 64, and is captured and adsorbed on the surface by the electrostatic adsorption plate 64.

[0033] When the pressure is applied, the electrostatic generator 61 and the electrostatic adsorption plate 64 stop working, and the blower 63 stops blowing. The air pump operates, generating negative pressure at the negative pressure port 66. Since the electrostatic adsorption plate 64 stops working and the static electricity on the electrostatic adsorption plate 64 is quickly conducted to the ground, the electrostatic adsorption plate 64 loses its charge adsorption force on the dust, and the dust can be adsorbed into the collection box 65 by gravity through the negative pressure at the negative pressure port 66.

[0034] In addition, when the pressing table 5 moves down, the driven block 72 moves up along the limiting groove 74 via the steel cable 73 and the fixed pulley 71. When the driven block 72 moves up, it drives the rotating rod 76 to rotate along the rotating seat 77. When the rotating rod 76 rotates, it drives the cleaning strip 75 to move down along the limiting rod 78, so that the cleaning strip 75 can automatically clean the surface of the electrostatic adsorption plate 64 and prevent dust on the surface of the electrostatic adsorption plate 64 from affecting the next dust collection.
