[0002] ‌ Round forging dies‌ are dies that turn a blank into a round forging. During the forging process, the blank is subjected to external forces in the round forging die, causing plastic deformation, thereby obtaining a round forging of the desired shape and size. Round forging dies are widely used in various industrial fields that require round forgings.

[0016] Furthermore, the mold calibration display structure includes a calibration bracket slot, a calibration sliding bracket, a power supply assembly, a display light assembly, a metal spring sheet 1, a metal partition, and a metal spring sheet 2. The calibration bracket slot is fixedly arranged on the arc-shaped side wall of the rotating card plate, and the calibration bracket slot opens upward. The calibration sliding bracket slides up and down along the calibration bracket slot. The calibration bracket slot is connected to the calibration sliding bracket by a spring.

[0022] The scheme provides a forging die inner wall detection device, and its beneficial effects are as follows: (1) According to the laser emitted by the double-layer laser emitter, the spatial height of the positioning device sleeve is adjusted so that the center of the positioning device sleeve coincides with the center of the bottom mold, and the forging table clamp is clamped on the front and back sides of the forging circular mold through the transmission of the ball screw assembly, so that the positioning device sleeve and the forging circular mold are relatively fixed. In order to reduce the probability of displacement of the positioning device sleeve when the upper mold is pressed downward, a suitable upper mold detection device is selected according to the specifications of the forging circular mold, and the bottom calibration bracket is driven to move through the chuck structure. The specifications of the forging circular mold are confirmed according to the moving distance of the bottom calibration bracket; (2) Increase the gravity at the bottom of the rotating pallet, making it perpendicular to the horizontal plane and parallel to the scale needle, ensuring that the bottom mold is installed on a relatively stable ground, and utilizing the displacement of the calibration sliding bracket caused by the downward pressure of the upper mold. When the metal springs 1 and 2 in the calibration sliding bracket contact the power supply component and the display light component respectively, electrical conduction is performed. The position of the small bulbs within different radii that light up can be determined based on the movement of the calibration sliding bracket. When all the small bulbs light up within a radius, the installation of the upper mold meets the standard. If small bulbs within different radius light up, the spatial position of the upper mold needs to be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The top wall of the calibration sliding bracket 41 is provided with a ball bearing, and the disc inserting block 34 is set in a three-dimensional rectangular shape.

[0041] The cart structure 3 includes a frame 47 , a bottom of the frame 47 is provided with rollers, and a handle is provided on the frame 47 .

[0042] The forging round die 1 comprises an upper die 48 and a bottom die 49. The upper die 48 is pushed by a cylinder, and the bottom die 49 is in contact with and connected to the upper die 48.

[0043] During specific use, after the upper die 48 and the bottom die 49 are respectively installed in the factory, the forging round die 1 needs to be calibrated. The uncalibrated forging round die 1 is at risk of damage during the forging process; the cart structure 3 is driven to move the die detection equipment 2 between the upper die 48 and the bottom die 49, the double-layer laser emitter 13 is powered on to emit laser, the ball screw 9 rotates, and the nut 10 slides along the ball screw 9. While dragging the positioning device sleeve 12 up and down, the laser trajectory emitted by the double-layer laser emitter 13 is adjusted in spatial height until one group of lasers is blocked by the edge of the bottom die 49 and the other group of lasers is not blocked. The operator needs to ensure that the two groups of double-layer lasers on both sides of the positioning device sleeve 12 are The laser emitter 13 meets the above requirements to ensure that the center of the positioning device sleeve 12 coincides with the center of the bottom mold 49; in order to fix the positioning device sleeve 12 relative to the forging circular mold 1, it is necessary to use mechanical equipment to fix the overall structure of the detection device to avoid displacement of the detection device when the upper mold 48 contacts the bottom mold 49. Therefore, the ball screw 2 15 is rotated to drive the screw slot 3 17 to move horizontally, so that the forging table clamp 20 moves to a position convenient for clamping both sides of the bottom mold 49. The ball screw 3 18 rotates to make the forging table clamp 20 continue to move. The two groups of forging table clamps 20 on the same side are first separated and then moved to the middle position to reduce the distance between them and the bottom mold 49, thereby positioning the device. The preparation sleeve 12 is fixed relative to the bottom mold 49 by mechanical clamping; then, in order to prevent the bottom of the detection equipment from falling when the upper mold 48 is pressed down, and to prevent the bottom of the detection equipment from falling and deforming due to multiple pressings of the upper mold 48, which affects the accuracy, the embedded chuck 21 is driven to rotate, and the turbine ridge 25 rotates while the bracket clamping plate 27 slides along the turbine ridge 25, and the position of the bottom calibration bracket 26 is changed. However, the bottom calibration bracket 26 is limited by the structural characteristics of the ridge linear groove 29, which causes the bottom calibration bracket 26 to slide in the direction of the ridge linear groove 29. The length of the bottom calibration bracket 26 extending from the positioning equipment sleeve 12 can be marked by the scale on the bottom calibration bracket 26. The length of movement determines the size of the engaging disc 32 to be selected; after the engaging disc 32 is inserted into the disc insertion slot 33 through the disc insertion block 34, the rotating clamping plate 38 swings on the central bracket 35 between the engaging disc 32 and the symmetrical limit plate 36. Limited by the gravity of the bottom counterweight 39, the falling direction of the rotating clamping plate 38 is perpendicular to the horizontal plane. Under the coordinated action of the laser positioning device 4, the mold fixing device 5 and the bottom mold supporting device 6, the scale needle 37 and the bottom counterweight 39 should be changed to a parallel position relationship. If an angle is generated between the bottom counterweight 39 and the scale needle 37, the positioning device sleeve 12 is not placed in a horizontal position, and the detection device needs to be readjusted in position;When the scale needle 37 and the bottom counterweight block 39 are parallel to each other when viewed from the front, the upper mold 48 is controlled to be pressed downward slowly, and the arc-shaped inner wall of the upper mold 48 contacts the calibration sliding bracket 41 on the rotating card plate 38. The calibration sliding bracket 41 slides into the calibration bracket slot 40 under the pressure of the upper mold 48. If during this process, the upper mold 48 presses the calibration sliding bracket 41, causing the rotating card plate 38 to deflect, it directly proves that the upper mold 48 is not aligned with the bottom mold 49, and the offset distance between the upper and lower molds is too large; when the calibration sliding bracket 41 can enter the calibration bracket slot without shaking the rotating card plate 38 40, and the metal spring piece 1 44 and the metal spring piece 2 46 transfer electric energy from the power supply assembly 42 to the display light assembly 43 when they are in contact with the power supply assembly 42 and the display light assembly 43 respectively. When multiple groups of small light bulbs within the same radius are all lit, it proves that the upper die 48 is aligned with the bottom die 49, and the installation error of the upper die 48 is small. If the small light bulbs within the same radius are not all lit, but the light bulbs within another outer diameter range are lit, it proves that the upper die 48 has a small error in the horizontal direction relative to the bottom die 49 that can affect the forging effect, and the position of the forging die needs to be readjusted. ;
