[0002] Stamping is the most common machining method in machining. Small, thin-walled parts are often processed by small punch presses. Common types of small punch presses include manual and pneumatic types.

[0003] In existing technologies, such as the Chinese patent application CN207724883U entitled "A Small Pneumatic Punch Press for Dies," a base is included, on which a control console and safety switch are mounted. The base has a lower base plate, on which a lower fixed plate, a fixed column, a sliding guide column, and a limiting column are mounted. Opposite the lower fixed plate is an upper fixed plate, which is fixed to the upper base plate and to one end of the fixed column. The upper base plate is equipped with a pressure regulating valve and a pneumatic booster cylinder. This small pneumatic punch press for dies involves locking the die fixture onto the lower and upper fixed plates as required. The height of the limiting column is adjusted according to the die fixture's stroke. After confirming the die fixture is properly installed and the limiting height is adjusted, the punching operation begins. After completing the required punching, the die fixture is removed, and the press is cleaned. The operation is simple. This pneumatic punch press is small in size, easily movable, and saves operating space. Furthermore, it uses air pressure for punching operations, saving electricity.

[0004] In the existing technology for stamping workpieces, most stamping cylinders require air compressors for pneumatic drive, which makes the operation of stamping cylinders more complicated and leads to inconvenience in using the punch press.

[0005] Therefore, it is necessary to provide a small electromagnetic punch press to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a small electromagnetic punch press, which solves the problem that most punching cylinders require air compressors for pneumatic drive, making the operation of punching cylinders more complicated and thus making the use of punch presses more inconvenient.

[0007] To solve the above-mentioned technical problems, this utility model provides a small electromagnetic punch press, including a support table and a control pedal. A fixing frame is fixedly connected to the side of the support table, and a housing is fixedly connected to one end of the fixing frame. An electromagnetic coil is fixedly sleeved inside the housing, and an iron core column is movably sleeved inside the housing. A punching column is fixedly connected to the bottom of the iron core column, and a spring is movably sleeved inside the housing. A transformer power supply is installed on the top of the support table. An anti-slip toothed plate is fixedly connected to the side of the control pedal. A lubrication mechanism is provided inside the housing. A limit mechanism is provided on the top of the iron core column. A positioning mechanism is provided on the top of the support table, and a moving mechanism is provided on the bottom of the support table.

[0008] Preferably, the iron core column is movably sleeved inside the electromagnetic coil, and the iron core column and the support platform are perpendicular to each other.

[0009] Preferably, one end of the spring is fixedly connected to the outside of the stamping column, and the spring is adapted to the housing.

[0010] Preferably, the anti-slip toothed plate is the same size as the bottom of the control pedal, and the anti-slip toothed plate is parallel to the support platform.

[0011] Preferably, the lubrication mechanism includes a limiting hole, which is opened at the bottom of the inner cavity of the housing, and a sliding ball is movably sleeved on the front side of the inner wall of the limiting hole.

[0012] Preferably, the limiting mechanism includes a limiting block, which is fixedly connected to the top of the iron core column, and a shock-absorbing pad is fixedly connected to the top of the housing, the shock-absorbing pad being made of rubber.

[0013] Preferably, the positioning mechanism includes a positioning seat, which is fixedly connected to the top of the support platform, and the top of the positioning seat is provided with a placement groove.

[0014] Preferably, the moving mechanism includes a support column, which is fixedly connected to the bottom of the support platform, and a sliding wheel is installed at the bottom of the support column.

[0015] Compared with related technologies, the small electromagnetic punch provided by this utility model has the following beneficial effects:

[0016] This utility model provides a small electromagnetic punch press. By setting an iron core column, when the workpiece is being punched, the workpiece is placed at the bottom of the punching column. At this time, pressing the control pedal allows the current inside the transformer power supply to be quickly conducted to the inside of the electromagnetic coil, thereby causing the electromagnetic coil to generate a huge magnetic force and attract the iron core column. When the iron core column is attracted by the electromagnetic coil, it drives the punching column to quickly squeeze to the top of the workpiece, thus achieving the effect of electromagnetic punching of the workpiece. This avoids the more complicated and cumbersome problems of pneumatic drive punch press, thereby improving the convenience of punch press use.

[0017] By setting a limiting mechanism, the limiting block can limit the downward movement of the iron core column when the workpiece is being stamped, thus avoiding the problem of the iron core column hitting the top of the housing and causing damage when it moves up and down with the limiting block. This achieves the shock absorption effect when the iron core column moves up and down, which is the same as the shock absorption effect when the electromagnetic punch press is working.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1This is a schematic diagram of a preferred embodiment of a small electromagnetic punch press provided by this utility model; Figure 2 for Figure 1 The image shows a front view of a small electromagnetic punch press. Figure 3 for Figure 1 The image shows a front view of the core column in a small electromagnetic punch press. Figure 4 for Figure 1 The diagram shows a cross-sectional view of the housing in a small electromagnetic punch press. The small electromagnetic punch press includes a support platform 1 and a control pedal 2. A fixing frame 3 is fixedly connected to the side of the support platform 1, and a housing 4 is fixedly connected to one end of the fixing frame 3. An electromagnetic coil 5 is fixedly sleeved inside the housing 4, and an iron core column 6 is movably sleeved inside the housing 4. A punching column 7 is fixedly connected to the bottom of the iron core column 6, and a spring 8 is movably sleeved inside the housing 4. A transformer power supply 9 is installed on the top of the support platform 1. An anti-slip toothed plate 10 is fixedly connected to the side of the control pedal 2. A lubrication mechanism 11 is provided inside the housing 4. A limit mechanism 12 is provided on the top of the iron core column 6. A positioning mechanism 13 is provided on the top of the support platform 1, and a moving mechanism 14 is provided on the bottom of the support platform 1.

[0025] The iron core column 6 is movably sleeved inside the electromagnetic coil 5, and the iron core column 6 is perpendicular to the support platform 1. By setting the iron core column 6, when the workpiece is being stamped, the workpiece is placed at the bottom of the stamping column 7. At this time, pressing the control pedal 2 allows the current inside the transformer power supply 9 to be quickly conducted to the electromagnetic coil 5, thereby generating a huge magnetic force in the electromagnetic coil 5 and attracting the iron core column 6. When the iron core column 6 is attracted by the electromagnetic coil 5, it drives the stamping column 7 to quickly squeeze to the top of the workpiece, thus achieving the electromagnetic stamping effect of the workpiece. This avoids the more complex and cumbersome problems of pneumatic drive of the punch press, thereby improving the convenience of using the punch press.

[0026] One end of the spring 8 is fixedly connected to the outside of the stamping column 7, and the spring 8 is adapted to the housing 4. By setting the spring 8, when the workpiece finishes a single stamping, the control pedal 2 is released, and when the current of the electromagnetic coil 5 disappears, the spring 8 can push the stamping column 7 to be lifted, thereby achieving the reset effect of the stamping column 7, which in turn brings convenience to the multiple stamping of the workpiece.

[0027] The anti-slip toothed plate 10 is the same size as the bottom of the control pedal 2, and the anti-slip toothed plate 10 is parallel to the support platform 1. By setting the anti-slip toothed plate 10, when the control pedal 2 is stepped on, the anti-slip toothed plate 10 greatly increases the friction between the ground and the bottom of the control pedal 2, thereby avoiding the problem of slipping when the control pedal 2 is stepped on, and thus improving the stability of the position of the control pedal 2.

[0028] The lubrication mechanism 11 includes a limiting hole 111, which is located at the bottom of the inner cavity of the housing 4. A sliding ball 112 is movably sleeved on the front side of the inner wall of the limiting hole 111. By setting the lubrication mechanism 11, when the stamping column 7 stamps the workpiece, the sliding ball 112 can limit the up-and-down movement of the stamping column 7, thereby avoiding the problem of friction between the stamping column 7 and the inner wall of the limiting hole 111 when it moves up and down inside the limiting hole 111, thus improving the smoothness of the stamping column 7 when it rises and falls.

[0029] The limiting mechanism 12 includes a limiting block 121, which is fixedly connected to the top of the iron core column 6. A shock-absorbing pad 122 is fixedly connected to the top of the housing 4. The shock-absorbing pad 122 is made of rubber. By setting the limiting mechanism 12, when the workpiece is being stamped, the limiting block 121 can limit the downward movement of the iron core column 6, thereby avoiding the problem of the iron core column 6 hitting the top of the housing 4 and causing damage when it moves up and down with the limiting block 121. This achieves the shock absorption effect when the iron core column 6 moves up and down.

[0030] The positioning mechanism 13 includes a positioning seat 131, which is fixedly connected to the top of the support platform 1. The top of the positioning seat 131 is provided with a placement groove 132. By setting the positioning mechanism 13, when the workpiece is being stamped, the workpiece is placed inside the placement groove 132, so that the placement groove 132 can position the workpiece and keep the workpiece directly below the stamping column 7, thereby achieving the positioning effect of the workpiece stamping position and avoiding the problem of large errors in the stamping position caused by the workpiece placement position shift.

[0031] The moving mechanism 14 includes a support column 141, which is fixedly connected to the bottom of the support platform 1. A sliding wheel 142 is installed at the bottom of the support column 141. By setting up the moving mechanism 14, when the electromagnetic punch press is moving and conveying, the support platform 1 is pushed, so that the sliding wheel 142 can drive the support platform 1 to move horizontally through the support column 141, that is, drive the housing 4 to move horizontally, thereby achieving the effect of moving and conveying the electromagnetic punch press, thus bringing convenience to the adjustment of the working position of the electromagnetic punch press.

[0032] The working principle of the small electromagnetic punch provided by this utility model is as follows:

[0033] Step 1: First, when stamping a workpiece, place the workpiece at the bottom of the stamping column 7. Then, press the control pedal 2, allowing the current inside the transformer power supply 9 to be quickly conducted to the electromagnetic coil 5. This generates a strong magnetic force in the electromagnetic coil 5, attracting the iron core column 6. When the iron core column 6 is attracted by the electromagnetic coil 5, it drives the stamping column 7 to quickly press against the top of the workpiece, achieving the electromagnetic stamping effect. This avoids the complex and cumbersome problems associated with pneumatic presses, thus improving the convenience of using the press. When a single stamping operation is complete, release the control pedal 2, causing the current in the electromagnetic coil 5 to disappear, and the spring 8 to release. The stamping column 7 is pushed to lift, thereby achieving the reset effect of the stamping column 7, which facilitates the multiple stamping of the workpiece. When the control pedal 2 is stepped on, the anti-slip toothed plate 10 greatly increases the friction between the ground and the bottom of the control pedal 2, thereby avoiding the problem of slippage when the control pedal 2 is stepped on, thus improving the stability of the position of the control pedal 2. When the stamping column 7 stamps the workpiece, the sliding ball 112 can limit the up and down movement of the stamping column 7, thereby avoiding the problem of friction between the stamping column 7 and the inner wall of the limit hole 111 when it moves up and down inside the limit hole 111, thus improving the smoothness of the stamping column 7 when it rises and falls.

[0034] Step 2: When the workpiece is being stamped, the limiting block 121 restricts the descent of the core column 6, preventing the core column 6 from impacting the top of the housing 4 and causing damage when it moves up and down with the limiting block 121. This achieves a shock absorption effect when the core column 6 moves up and down. When the workpiece is being stamped, it is placed inside the placement slot 132, which positions the workpiece so that it is kept directly below the stamping column 7. This achieves the positioning effect of the workpiece stamping position and avoids the problem of large errors in the stamping position caused by the workpiece being placed off-center. When the electromagnetic punch press is being moved and conveyed, the support table 1 is pushed, so that the sliding wheel 142 moves horizontally through the support column 141, which in turn moves the housing 4 horizontally. This achieves the moving and conveying effect of the electromagnetic punch press and facilitates the adjustment of the working position of the electromagnetic punch press.

[0035] Compared with related technologies, the small electromagnetic punch provided by this utility model has the following beneficial effects:

[0036] By setting the iron core column 6, when the workpiece is being stamped, the workpiece is placed at the bottom of the stamping column 7. At this time, pressing the control pedal 2 allows the current inside the transformer power supply 9 to be quickly conducted to the inside of the electromagnetic coil 5, thereby causing the electromagnetic coil 5 to generate a huge magnetic force and attract the iron core column 6. When the iron core column 6 is attracted by the electromagnetic coil 5, it drives the stamping column 7 to quickly squeeze to the top of the workpiece, thus achieving the electromagnetic stamping effect of the workpiece. This avoids the more complicated and cumbersome problems of pneumatic drive of the punch press, thereby improving the convenience of using the punch press.
