Description

Technical Field

[0001] This utility model relates to the technical field of sampling tools for punching machines, specifically a sampling tool for use after a sample is jammed in a punching machine. Background Technology

[0002] Currently, if the sheet metal gets stuck between the punches after the prototyping machine finishes making the sample, it is necessary to use needle-nose pliers to insert the tip of the pliers between the punches. ， Clamp the edge of the sheet metal, shake it vigorously, and slowly pull the sheet metal off. However, this process is extremely difficult because the worktable and punch of the punching machine work in a narrow chamber. During normal operation, the chamber door must be closed to prevent accidents. This results in limited space to shake the sheet metal with pliers, making sampling more difficult. Moreover, the distance between the punches is very close. When the sheet metal sample is already small, it can get stuck after punching. It is even more difficult for the tip of the pliers to clamp the edge of the sheet metal. Sometimes, it is necessary to use a thin stick to be inserted diagonally downwards from above into the gap between the punches. The stuck sample is placed under the thin stick, and the other side of the thin stick is struck with a hammer to make the stuck sheet metal slowly move down from the punch and eventually fall off.

[0003] The existing sampling method using needle-nose pliers is only suitable for larger samples. It is no longer applicable if the sample is small and cannot be clamped, resulting in a large limitation of application. Even if the sample is large, it can be clamped by the edge of the sample and shaken and pulled. However, in this case, only one side can be clamped, while the other three sides are blocked by other components of the equipment and cannot be reached. This causes uneven force on the stuck sample, which may cause the sample to tilt and aggravate the jamming problem. In addition, due to the limited operating space, the operator is prone to bumping into the surrounding frame during shaking and pulling, which may cause injury or scratches.

[0004] The existing technology uses a thin stick to pry open the four punches in a square shape with a certain distance between the sides and the middle of the square. However, this distance is small, and only very thin sticks with a diameter of about 2mm can be selected to accommodate them. Because these are not special thin sticks, most of them are very soft and not hard enough. As a result, when they are inserted between the punches and the other side is hit with a hammer, they are prone to bending. This makes it difficult to achieve the prying operation, resulting in poor operability and low efficiency.

[0005] Both of the above sampling methods have problems such as the difficulty of using tools and limited operating space, which result in low sampling efficiency and may also lead to risks such as injury to staff, damage to samples, and damage to the sampling machine. Utility Model Content

[0006] The purpose of this utility model is to provide a sampling tool for removing jammed samples after a sample punching machine has been used. This tool can quickly remove jammed samples, improve sampling efficiency, is applicable to jamming situations that occur after sample preparation of samples of different sizes, and can avoid risks such as injury to staff, damage to samples, and damage to the sample punching machine.

[0007] To achieve the above-mentioned technical effects, this utility model provides a sampling tool for removing samples after they are stuck in a punching machine. The tool includes a perforated steel plate I, a perforated steel plate II, and a non-perforated steel plate. The perforated steel plate I and the perforated steel plate II are parallel. The perforated steel plate I has a receiving groove on its upper part, and the perforated steel plate II has a receiving plate on its upper part. The end of the receiving plate away from the perforated steel plate II is inserted into the receiving groove. The receiving plate is inserted between multiple punches of the punching machine and rests on the top surface of the sample stuck in the punches of the punching machine. The perforated steel plate I has a connecting groove I at its lower part, and the perforated steel plate II has a connecting groove II at its lower part. The connecting groove I and the connecting groove II are coaxial. The non-perforated steel plate is inserted into the connecting groove I and the connecting groove II. The non-perforated steel plate is positioned below the sample stuck in the punches of the punching machine, and both ends of the non-perforated steel plate extend out of the connecting groove I and the connecting groove II, respectively.

[0008] Furthermore, the receiving plate is provided in three parts, which are linearly and evenly distributed along the width direction of the perforated steel plate II. The ends of the three receiving plates away from the perforated steel plate II are all inserted into the receiving groove. The middle receiving plate is inserted between multiple punches of the punching machine. The two receiving plates on the outer sides of the three receiving plates are respectively inserted on the outer sides of multiple punches of the punching machine. The three receiving plates are all supported on the top surface of the sample held by the punches of the punching machine.

[0009] Furthermore, multiple connecting grooves I are provided on the perforated steel plate I, and the multiple connecting grooves I are linearly and evenly distributed along the height direction of the perforated steel plate I. Multiple connecting grooves II are provided on the perforated steel plate II, and the multiple connecting grooves II are linearly and evenly distributed along the height direction of the perforated steel plate II. The multiple connecting grooves I and the multiple connecting grooves II are coaxial.

[0010] Furthermore, the receiving groove is a rectangular groove.

[0011] Furthermore, both connecting groove I and connecting groove II are rectangular grooves, and the shapes of connecting groove I and connecting groove II are the same.

[0012] Furthermore, all three receiving plates are welded onto the perforated steel plate II.

[0013] The beneficial effects of this utility model are: This utility model is simple and easy to operate, applicable to all sizes of stuck samples, with a wide range of applications. The stuck sample is subjected to force as a whole, and there will be no uneven force causing the sample to tilt, which would lead to more serious sample jamming problems. It can quickly and efficiently remove stuck samples without affecting subsequent work, improve work efficiency, and avoid risks such as injury to staff, damage to samples, and damage to the punching machine.

[0016] like Figures 1-6 As shown, this utility model discloses a sampling tool for use after sample clamping in a punching machine, comprising a perforated steel plate I1, a perforated steel plate II2, and a non-perforated steel plate 3. The perforated steel plate I1 is parallel to the perforated steel plate II2. The perforated steel plate I1 has a receiving groove 4 on its upper part, and the perforated steel plate II2 has a receiving plate 6 on its upper part. One end of the receiving plate 6 away from the perforated steel plate II2 is inserted into the receiving groove 4. There are three receiving plates 6, linearly and evenly distributed along the width direction of the perforated steel plate II2. The ends of all three receiving plates 6 away from the perforated steel plate II2 are inserted into the receiving groove 4. The middle receiving plate 3... Plate 6 is inserted between multiple punches of the punching machine. Two of the two outer sides of the three supporting plates 6 are respectively inserted into the two outer sides of the multiple punches of the punching machine. All three supporting plates 6 are supported on the top surface of the sample held by the punches of the punching machine. The perforated steel plate I1 has a connecting groove I5 at the bottom, and the perforated steel plate II2 has a connecting groove II7 at the bottom. The connecting groove I5 and the connecting groove II7 are coaxial. The non-perforated steel plate 3 is inserted into the connecting groove I5 and the connecting groove II7. The non-perforated steel plate 3 is located below the sample held by the punches of the punching machine. The two ends of the non-perforated steel plate 3 extend out of the connecting groove I5 and the connecting groove II7, respectively.

[0017] Multiple connecting grooves I5 are provided on the perforated steel plate I1, and the multiple connecting grooves I5 are linearly and evenly distributed along the height direction of the perforated steel plate I1. Multiple connecting grooves II7 are provided on the perforated steel plate II2, and the multiple connecting grooves II7 are linearly and evenly distributed along the height direction of the perforated steel plate II2. The multiple connecting grooves I5 and the multiple connecting grooves II7 are coaxial.

[0018] The receiving groove 4 is a rectangular groove.

[0019] Both connecting groove I5 and connecting groove II7 are rectangular grooves, and the connecting groove I5 and connecting groove II7 have the same shape.

[0020] All three support plates 6 are welded onto the perforated steel plate II2.

[0021] After the punching machine finishes punching, a jamming phenomenon occurs when the punch rises again. The sample gets stuck on the punch and burns along with it. At this time, insert the perforated steel plate I1 from bottom to top behind the four punches, ensuring that the receiving groove 4 on the perforated steel plate I1 is higher than the jammed sample. Then, place the side of the perforated steel plate II2 connected to the receiving plate 6 towards the perforated steel plate I1, making the receiving plate 6 higher than the jammed sample. Align the three receiving plates 6 with the receiving groove 4. Figure 5 and Figure 6 As shown, the four punches of the punching machine are arranged in a square shape, with gaps on both sides and in the middle of this square. Three receiving plates 6 pass through the gaps on both sides and in the middle of the square formed by the four punches and are inserted into the receiving grooves 4. At this time, the three receiving plates 6 support the sample above it. Then, the non-perforated steel plate 3 is passed through any pair of connecting grooves I5 and II7 below the receiving plates 6. It is necessary to ensure that the non-perforated steel plate 3 is kept horizontal and that both ends of the non-perforated steel plate 3 extend out of the connecting grooves I5 and II7 respectively. Neither end of the non-perforated steel plate 3 should simply overlap the connecting groove I5 or the connecting groove II7. After confirming that the non-perforated steel plate 3 is connected in place, two hammers are used to simultaneously strike the two ends of the non-perforated steel plate 3 extending out of the connecting grooves I5 and II7 respectively. In this way, the sample is dragged downward by the perforated steel plate I1, the perforated steel plate II2 and the receiving plates 6 until the sample is detached from the punch, and the work is completed.

[0022] Because the position of the sample clip on the punch is uncertain, sometimes it is high and sometimes it is low. The different heights of the sample clipping position on the punch mean that the length of the sample extending from the lower end of the punch is different. To accommodate this difference, this utility model is provided with multiple connecting grooves I5 and II7. The multiple connecting grooves I5 and II7 are designed to accommodate the different lengths of the sample extending from the lower end of the punch, thus improving the applicability of this utility model. In actual use, it is generally recommended to select connecting grooves I5 and II7 that are close to the lower end of the punch to connect the non-perforated steel plate 3, while also considering the installation space of the non-perforated steel plate 3.

[0023] In this invention, the three receiving plates 6 ensure that the stuck sample is subjected to force simultaneously, preventing uneven force from causing sample tilting and leading to more serious sample jamming problems, and ensuring that the structure is not damaged after the sample is removed.
