Description

Technical Field

[0001] This utility model relates to the technical field of steel component processing equipment, and more specifically, to a positioning device for a steel component punch press. Background Technology

[0002] Stamping is a common processing method in steel component manufacturing, requiring stamping-related equipment such as punching machines and shearing machines. Taking shearing machines as an example, before shearing, cutting lines must be drawn on the steel plate, and then the cutting lines are moved to the blade position for cutting. Current technology generally uses light for positioning. A beam of light is shone onto the steel plate, and the boundary line of the beam on the steel plate corresponds to the blade position. Therefore, the cutting line is moved until it coincides with the boundary line of the beam. However, the light beams from existing shearing machines are weak and of a single color, easily blending with ambient light, making the light beam boundary line indistinct and further complicating positioning.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments 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. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Example:

[0023] like Figures 1-3 As shown, this utility model provides a positioning device for a steel component punch press, used in conjunction with a machine tool. Taking a shearing machine as an example, the machine tool is equipped with a cutting station. The cutting station is equipped with a horizontal cutter 1 and a vertical cutter 2 that cooperate with each other. The vertical cutter 2 descends and passes close to the horizontal cutter 1. If a workpiece is placed below the vertical cutter 2, it will cooperate with the horizontal cutter 1 to cut the workpiece when it passes through. The punch press positioning device includes an illumination source 3 and a positioning light source 4. The illumination source 3 faces the cutting station. The illumination source 3 can be white light, which has good adaptability and wide application scenarios. Other colors can also be used. The irradiation surface of the positioning light source 4 is the positioning line, which is linear. That is, after the positioning light source 4 illuminates the cutting station, it forms a straight line composed of light spots at the cutting station. The positioning line is located at the contact line between the vertical cutter 2 and the workpiece, that is, the positioning line is located on the surface of the workpiece and at the contact line between the vertical cutter 2 and the workpiece during its descent. The color of the positioning line is different from the color of the lighting source 3; it can be a combination of white lighting and red positioning source 4. The key is to ensure a clear color difference between the two.

[0024] When using the steel component punching machine positioning device of this utility model, the lighting source 3 illuminates the cutting station, making it easy to observe the current position of the cutting line on the workpiece surface. Simultaneously, the positioning line emitted by the positioning light source 4 indicates the cutting position. The workpiece is placed on the horizontal cutter 1 and gradually pushed below the vertical cutter 2. Cutting can begin when the cutting line on the workpiece coincides with the positioning line. At this point, the vertical cutter moves downwards and cuts the workpiece along the cutting line.

[0025] The illumination from light source 3 makes the marked cutting lines on the workpiece clearly visible. The positioning lines, being a different color from light source 3, are also very prominent, making it easier to distinguish whether the cutting lines and positioning lines overlap.

[0026] In this embodiment, the machine tool further includes a frame 5. A rotating rod 6 is provided along the width direction of the frame 5. The rotating rod 6 is rotatable relative to the frame 5. Figure 2 As shown, the frame 5 is also equipped with a first worm gear 7 in conjunction with the rotating rod 6. The first worm gear 7 is connected to the first worm wheel of the rotating rod 6, and its other end extends out of the frame 5 and is located on the front of the frame 5. The positioning light source 4 is elongated and is disposed on the rotating rod 6 along the length of the rotating rod 6.

[0027] In operation, turning the first worm gear 7 will rotate the rotating rod 6, which in turn will rotate the positioning light source 4. In practice, different workpieces have different thicknesses. Therefore, the angle of the positioning light source 4 needs to be adjusted to ensure that the positioning line coincides with the cutting line when the vertical cutter 2 contacts the workpiece. Due to the cooperation of the worm gear and the worm, once the angle of the positioning light source 4 is adjusted, the mechanical vibration of the machine tool will not cause the rotating rod 6 to rotate, thus ensuring stability. Furthermore, the first worm gear 7 extends to the front of the frame 5, facilitating operation by the operator from in front of the frame 5.

[0028] In this embodiment, a comparison light source 9 is also provided. The illumination surface of the comparison light source 9 is the comparison line, and the comparison light source 9 is positioned directly opposite the horizontal cutter 1 from top to bottom. That is, after the comparison light source 9 illuminates the cutting station, it forms a straight line composed of light spots at the cutting station. The comparison line is linear. Figure 3 As shown, the comparison light source 9 is equipped with a rotating shaft. A second worm gear 10 is mounted on the rotating shaft. A second worm 11 is also mounted on the second worm gear 10 to drive the second worm gear 10 to rotate. One end of the second worm 11 extends out of the frame 5 and is located on the front of the frame 5. When the second worm 11 rotates, the comparison light source 9 rotates in the horizontal plane.

[0029] Alignment lines assist positioning lines in workpiece positioning. For example, if a rectangular plate needs to be cut, and the cutting line forms a 60-degree angle with the edge of the rectangular plate, we can adjust the angle of the alignment light source 9 so that the angle between the alignment line and the positioning line is 60 degrees. When the cutting line coincides with the positioning line, the edge of the rectangular plate also coincides with the alignment line. In this way, the rectangular plate can be positioned by combining the alignment line and the positioning line.

[0030] In practice, if only positioning lines and cutting lines are used to position the workpiece, the slight errors between them are difficult to observe due to the uncertainty of visual observation. However, using a comparison line can make the errors more obvious, thus facilitating the correction of the workpiece position.

[0031] In this embodiment, a slide rail 12 is also included, which is arranged along the length of the horizontal cutter 1. For example... Figure 2 As shown, the comparison light source 9 is provided with a base 13. The base 13 is slidably sleeved on the slide rail 12. The comparison light source 9 is rotatably mounted on the base 13, and the second worm gear 10 is disposed inside the base 13. A sleeve 8 is provided on the base 13 along the length direction of the second worm 11, and the sleeve 8 extends to the outside of the frame 5. The second worm 11 passes through the inside of the sleeve 8. The front of the frame 5 is provided with a slot for the sleeve 8 to slide.

[0032] In use, the second worm gear 11 can be moved along the width of the frame 5 to make the base 13 slide along the track. This allows the comparison light source 9 to be moved to the appropriate position.

[0033] In this embodiment, the slide rail 12 has a rectangular cross-section. The base 13 is provided with a rectangular hole to cooperate with the slide rail 12. This allows the base 13 to slide relative to the slide rail 12 and not rotate relative to it.

[0034] In this embodiment, multiple sets of comparison light sources 9 are provided, all of which are connected to the slide rail 12 via a base 13. Multiple sets of comparison light sources 9, in conjunction with the positioning light source 4, enable better positioning.

[0035] In this embodiment, the lighting source 3 is disposed on one side of the frame 5 and shines obliquely upwards onto the horizontal cutter 1. For example... Figure 2 As shown, based on the placement of the lighting source 3, the light from the lighting source 3 can pass under the vertical cutter 2 and illuminate the area behind the vertical cutter 2. Even if the cutting line is pushed slightly below or behind the vertical cutter 2 as the workpiece is gradually pushed downwards, the lighting source 3 can still illuminate the cutting line. This facilitates timely correction by the operator.

[0036] In this embodiment, the colors of the illumination source 3, the positioning source 4, and the comparison source 9 are all adjustable. This allows the color of the light to be adjusted as needed, making it easier to identify the condition of the workpiece and improving the accuracy of positioning.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
