Technical Field

[0001] This utility model relates to the technical field of hydraulic forging hammer testing devices, and in particular to a novel hydraulic forging hammer impact energy testing device. Background Technology

[0002] Hydraulic forging hammers are the most widely used equipment in forging, mainly divided into free forging and die forging. They are widely used in the high-precision forging and hot forging blank industries. The accuracy of the impact energy of hydraulic forging hammers directly affects the quality and precision of forgings. Traditional impact energy detection methods include hitting copper pillars and using magnetic scales to detect hammer head speed. When using copper pillars, the copper pillars are disposable consumables, resulting in high detection costs. The magnetic scale method for detecting hammer head speed involves complex manufacturing processes. There is an urgent need to invent a low-cost device that is easy to manufacture and install to measure the actual impact energy of hydraulic forging hammers. Utility Model Content

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] Example 1

[0030] Please refer to Figure 1 The technical solution of this utility model is: a novel hydraulic forging hammer impact energy detection device, which, as a specific embodiment, includes:

[0031] The marking element 3 is set on the hammer head 2, and two marking parts are set at intervals along the striking direction of the hammer head 2;

[0032] Detection component 4 is used to detect the marking part;

[0033] The time module 7 is connected to the detection element 4 and is used to obtain the time interval between the two marking parts passing the detection element 4.

[0034] For details, please refer to Figure 1The technical solution of this application is as follows: When performing energy detection on a hydraulic forging hammer, a detection element 4 is placed on one side of the hammer head 2, stationary relative to the ground. Specifically, it can be placed on a frame or on the ground. A marking element 3 is placed on the hammer head 2 being tested. A forging is placed on the forging hammer platform, and the height of the detection element 4 is adjusted so that it is slightly higher than the upper surface H1 of the forging. Then, the forging energy detection of the hammer head 2 begins. When the hammer head 2 begins forging, it passes through the detection element 4. When it passes through the detection element 4 at one end of the marking area, the detection element 4 detects the detection part and records the passing time point. When it passes through the detection element 4 at one end of the marking area, a second time point is recorded. The time difference t between the two time points can be obtained. The speed of the hammer head 2 is obtained using the formula V = (H-H1) / t, where H is the distance between the two ends of the marking area. When using a label, the thickness of the label paper is used. Then, the speed of the hammer head 2 is obtained based on the interval distance between the two detection parts. Then, the energy is calculated using the formula E = ... mv2 / 2 can accurately measure the impact energy. This method can accurately calculate the energy of the hammer head 2. Moreover, the overall structure of this detection device is simple, and the detection and usage costs are low.

[0035] Further, as a preferred embodiment, the marking element 3 is a color marking element, and the detection element 4 is a color mark sensor. Specifically, the marking element 3 can be a color marking element, such as a label. The label is pasted onto the lower end of the hammer head 2 like a piece of paper. The back of the label is coated with high-viscosity double-sided adhesive, which can firmly install it onto the hammer head 2. Because the label is very light, it can avoid the label being thrown off by the high impact and high vibration of the forging hammer during striking. It also has the advantage of low cost. When in use, the label is pasted directly below the hammer head 2. In the actual detection process, the label uses white label paper with a standard thickness, generally 20mm. The two marking parts are the two sides in the thickness direction of the label paper. Specifically, a color mark sensor manufactured by SICK GmbH of Germany is selected. This sensor has non-contact, high-precision contrast detection, shielded metal shell, IP67 protection rating, color mark self-learning and other functions. The signal adopts NPN output, and the time module 7 adopts...

[0036] During testing, when hammer 2 moves downwards, the color mark sensor detects the white label and outputs a high level. Time module 7 detects the rising edge of the high input level and begins recording time. When the 20mm white label slides past the color mark sensor, the high output level ends, and time module 7 detects the falling edge of the high input level and stops recording time, saving the recorded time. The velocity of the hammer 2's end point is calculated using V=S / T, and the impact energy is calculated using the energy formula E=mv² / 2. This impact energy detection device is already in normal use at the forging customer's site, used to detect the accuracy of the impact energy of each hydraulic forging hammer, with excellent results. Time module 7 can be manufactured by Siemens, model 6ES7138-6CGOO-OBAO. During operation, through isochronous synchronization mode, it can accurately calculate the movement time of a standard 20mm white label with an accuracy of 10 microseconds.

[0037] Further, refer to Figure 1 The color mark sensor is connected to the time module 7 via connecting cable 6. Connecting cable 6 connects the color mark sensor and the time module 7 via an M12 plug. Finally, the impact energy is calculated by programming the PLC central controller 8 and displayed on the display screen 9. The display screen 9 is an HMI touch screen 9. The model of the PLC central controller 8 is CPU1513-1PN.

[0038] Example 2

[0039] The technical solution of this utility model is: a novel hydraulic forging hammer impact energy detection device. As a specific implementation method, see reference... Figures 2-4 The system also includes a fixed bracket 5, which is vertically mounted and stationary relative to the ground. It includes a vertically telescopic rod and a horizontally adjustable rod 54. The detection element 4 is located at the end of the horizontally adjustable rod 54. Specifically, the telescopic rod has a connecting plate 53 at its lower end, which connects to the machine body 1. The telescopic rod includes a first guide rod 50 and a second guide rod 51. This allows for height adjustment of the top detection element 4. When the fixed bracket 5 is installed, the horizontally adjustable rod 54 is adjusted radially towards the hammer head 2, thereby adjusting the distance between the detection element 4 and the hammer head 2. During testing, the distance between the detection element 4 and the label is approximately 15 mm.

[0040] In one specific implementation, the first rod 50 is guided inside the second rod 51, and a locking bolt 52 is provided on the outer wall of the second rod 51. When the length of the telescopic rod is adjusted appropriately, the second rod 51 can be locked by locking the bolt 52.

[0041] In some embodiments, the first rod 50 and the second rod 51 can be adjusted by using an electric telescopic rod, which is commonly used in the prior art. The telescopic rod can be used to adjust the extension and retraction of the first rod 50 and the second rod 51.

[0042] Furthermore, as a specific implementation method, refer to Figures 4-7 The telescopic rod has a rotating sleeve 551 rotatably mounted at its end, and a guide sleeve 55 is mounted on the rotating sleeve 551. The horizontal adjusting rod 54 is guided and mounted inside the guide sleeve 55. Specifically, at the upper end of the second rod 51, a rotating sleeve 551 is rotatably fitted along the vertical axis. The guide sleeve 55 is integrally mounted on the rotating sleeve 551. The horizontal adjusting rod 54 is guided and fitted with the guide sleeve 55. By setting the rotating sleeve 551, when no inspection is being performed, the rotating sleeve 551 can be deflected by 90 degrees, causing the inspection piece 4 to deflect away from the hammer head 2, thus not affecting the use of the forging hammer.

[0043] Furthermore, the guide sleeve 55 is in a non-rotational circumferential engagement with the horizontal adjusting rod 54. (Reference) Figure 6 , Figure 7 The horizontal adjusting rod 54 has a groove 542 on its outer circumferential surface, and the guide sleeve 55 has a protrusion on its inner circumferential surface that mates with the groove 542, thus forming a non-rotational fit. This arrangement ensures that the horizontal adjusting rod 54 does not rotate, guaranteeing the accurate position of the detection piece 4. The guide sleeve 55 has a threaded hole 550 on its side wall, allowing a screw to be threaded into the hole. The screw locks and releases the horizontal adjusting rod 54, thereby adjusting its position.

[0044] Furthermore, as a specific implementation method, refer to Figure 5 A fitting sleeve 510 and a stepped shaft 511 are coaxially arranged at the upper end of the second rod 51. A bearing 58 is sleeved on the outside of the stepped shaft 511, and a bearing seat 57 is sleeved on the outside of the bearing 58. The rotating sleeve 551 is detachably connected to the bearing seat 57. The rotating sleeve 551 is detachably fixed to the bearing seat 57 by a second fixing bolt 552. The above arrangement facilitates the assembly of the rotating sleeve 551.

[0045] Furthermore, as a specific implementation method, refer to Figure 5 , Figure 7 The rotating sleeve 551 is equipped with a positioning component 56. Along the rotation axis of the rotating sleeve 551, the telescopic rod is provided with two positioning parts that are adapted to the positioning component 56. Specifically, by setting the two positioning parts to be circumferentially spaced at 90 degrees, the positioning component 56 on the rotating sleeve 551 can be positioned and engaged with the positioning parts. When engaged with one positioning part, the axis of the horizontal adjusting rod 54 is set radially along the hammer head 2. With this arrangement, the rotating sleeve 551 can be positioned by the positioning component 56.

[0046] For details, please refer to Figure 4 A detachable fixed connecting sleeve 540 is provided at the end of the horizontal adjusting rod 54, and the detection piece 4 is locked onto the connecting sleeve 540 by the first fixing bolt 541.

[0047] Furthermore, the specific structure of the positioning component 56 is as follows: the positioning component 56 includes a guide rod 561 that is radially guided and inserted into the side wall of the rotating sleeve 551, and an elastic element disposed between the connecting cylinder 562 and the guide rod 561. The elastic element can provide elastic force to the guide rod 561 in the direction of the axis of the rotating sleeve 551. The positioning part is a positioning hole 512.

[0048] Furthermore, a connecting cylinder 562 is provided around the guide rod 561 on the outer side wall of the rotating sleeve 551. An end cap 563 is detachably fitted at the end of the connecting cylinder 562. A flange plate 5610 is provided on the upper part of the guide rod 561. The elastic element is a compression spring 564 disposed between the flange plate 5610 and the end cap 563.

[0049] Specifically, the other end of the guide rod 561 extends out of the end cover 563 and is guided and engaged with the end cover 563. The end is threadedly connected to the end plate 565. In use, by holding the end plate 565, the guide rod 561 is pulled outward. At this time, the compression spring 564 is compressed, causing the guide rod 561 to be pulled out of the positioning hole 512. At this time, the rotating sleeve 551 can rotate. After rotating to the appropriate position, it is released. Under the elastic force of the compression spring 564, the guide rod 561 extends into the positioning hole 512 and is locked.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
