Description

Technical Field

[0001] The present invention belongs to the technical field of mold detection equipment, and specifically refers to an inner wall detection equipment for forging round molds. Background Art

[0002] ‌A forging round mold‌ is a mold that makes a blank into a round forging. During the forging process, the blank is subjected to external forces in the forging round mold, resulting in plastic deformation, so as to obtain round forgings with the required shape and size. Forging round molds are widely used in various industrial fields that require round forgings. For example, in the automotive manufacturing industry, many key components such as engine crankshafts, connecting rods, gears, etc. need to be produced through forging round molds. These components not only require high strength and high precision, but also must have good reliability and durability.

[0003] After the forging round mold is installed, it is necessary to calibrate the mold. If the mold is not calibrated and the forging task is carried out, it is easy to damage the mold and also make the forged material unqualified. Summary of the Invention

[0004] In view of the above situation, in order to ensure the normal operation of the forging round mold, the present invention provides an inner wall detection equipment for forging round molds, which performs spatial detection on the installed forging round mold to detect the data obtained by the forging round mold and adjust the position of the forging round mold.

[0005] The technical solution adopted by the present invention is as follows: An inner wall detection equipment for forging round molds provided by the present invention includes a forging round mold and a mold detection equipment. The mold detection equipment includes a trolley structure, a laser positioning device, a mold fixing device, a bottom mold support device, and an upper mold detection device. The trolley structure slides on the ground. The laser positioning device is clamped and slid up and down in the trolley structure. The bottom mold support device is clamped and rotatably installed on the laser positioning device. The mold fixing device is fixedly installed on the side wall of the laser positioning device. The upper mold detection device is clamped and installed at the center of the circle of the laser positioning device.

[0006] Further, the laser positioning device includes a screw groove 1, a ball screw 1, a nut 1, a connecting bracket, a positioning equipment sleeve, and a double-layer laser emitter. The screw groove 1 is arranged on the side wall of the trolley structure. The ball screw 1 is clamped and rotated in the screw groove 1. The nut 1 is threadedly connected to the ball screw 1, and the nut 1 slides up and down along the screw groove 1. The connecting bracket is fixedly installed on the nut 1. The positioning equipment sleeve is fixedly connected to the connecting bracket. The double-layer laser emitter is fixedly arranged on the side wall of the positioning equipment sleeve.

[0007] Preferably, the double-layer laser emitter emits two sets of lasers. During the test, one set of lasers is blocked by the circular forging die, and the other set of lasers is not blocked by the circular forging die, that is, it is determined that the spatial height of the center of the positioning device sleeve reaches the spatial height where the center of the circular forging die is located.

[0008] Further, the die fixing device includes a side screw groove two, a ball screw two, a nut two, a screw groove three, a ball screw three, a nut three, and a forging table clamping plate. The side screw groove two is fixedly installed on the side wall of the positioning device sleeve. The ball screw two is rotatably engaged in the side screw groove two. The nut two is threadedly connected to the ball screw two. The nut two slides along the ball screw two, and the nut two is horizontally slidably engaged in the side screw groove two. The screw groove three is fixedly installed on the nut two. The ball screw three is rotatably engaged in the screw groove three. The nut three is threadedly connected to the ball screw three, and the nut three slides horizontally along the screw groove three. The forging table clamping plate is fixedly installed on the side wall of the nut three.

[0009] Further, the ball screw one, the ball screw two, and the ball screw three are respectively driven by motors. There are two ball screws three with opposite rotation directions in a group of screw grooves three, so as to achieve the design effect of clamping two forging table clamping plates on the same side towards the middle position.

[0010] Further, the bottom die support device includes an embedded chuck, a chuck placement groove, a rotation limit groove, an annular rotation limit block, a turbine rib, a bottom calibration bracket, a bracket clamping plate, a vertical rib, and a rib linear groove.

The vertical rib slides along the rib linear groove. One side of the bottom calibration bracket is fixedly connected to the vertical rib. The bracket clamping plate is fixedly connected to the other side of the bottom calibration bracket. The bracket clamping plate slides along the turbine rib. When the embedded chuck rotates and the bracket clamping plate slides along the turbine rib, the bottom calibration bracket also slides along the turbine rib at the same time, and the bottom calibration bracket is restricted by the connection relationship between the vertical rib and the rib linear groove, achieving the design effect of sliding the bottom calibration bracket out of the chuck placement groove.

[0011] Further, the chuck placement groove is set as a cylindrical structure. The embedded chuck is driven by a motor to rotate. The edge of the bottom wall of the bottom calibration bracket is provided with a rounded corner.

[0012] Further, a scale is provided on the side wall of the bottom calibration bracket.

[0013] Further, the upper die detection device includes a gravity self-adjusting clamping structure and a die calibration display structure. The gravity self-adjusting clamping structure is clamped and installed at the center of the positioning device bushing, and the die calibration display structure is clamped and slidably installed within the gravity self-adjusting clamping structure.

[0014] Further, the gravity self-adjusting clamping structure includes a clamping disc, a disc insertion slot, a disc insertion block, a central support, symmetric limit plates, scale needles, a rotating clamping plate, and a bottom counterweight. The disc insertion slot is fixedly arranged at the center of the positioning device bushing. The disc insertion block is clamped and slidably nested within the disc insertion slot. One side of the clamping disc is fixedly installed on the disc insertion block. The central support is fixedly connected to the other side of the clamping disc. The symmetric limit plates are fixedly connected to the central support. The scale needles are fixedly arranged on the symmetric limit plates. The rotating clamping plate is clamped and rotatably arranged on the central support. The bottom counterweight is fixedly installed on the bottom wall of the rotating clamping plate.

[0015] Further, bearings are provided at the clamping connection between the symmetric limit plates and the rotating clamping plate, and bearings are provided at the clamping connection between the rotating clamping plate and the clamping disc to reduce the resistance when the rotating clamping plate rotates. At the same time, the bottom counterweight ensures that the rotating clamping plate is always perpendicular to the horizontal plane.

[0016] Further, the die calibration display structure includes a calibration support slot, a calibration sliding support, a power supply component, a display lamp component, a metal spring piece one, a metal partition, and a metal spring piece two. The calibration support slot is fixedly arranged on the arc-shaped side wall of the rotating clamping plate, and the opening of the calibration support slot faces upward. The calibration sliding support slides up and down along the calibration support slot. A spring is connected between the calibration support slot and the calibration sliding support. The power supply component is fixedly installed on one side of the side wall of the calibration support slot. The display lamp component is fixedly installed on the other side of the side wall of the calibration support slot. The calibration sliding support is provided with a slot penetrating both sides of its side wall. The metal partition is fixedly installed in the slot. The metal spring piece one is clamped and slidably installed on one side of the metal partition. The metal spring piece two is slidably installed on the other side of the metal partition, and both the metal spring piece one and the metal spring piece two are clamped and slidably installed in the slot. A spring made of a metal conductive material is connected between the metal spring piece one and the metal partition. A spring made of a metal conductive material is connected between the metal spring piece two and the metal partition.

[0017] Further, the display lamp assembly is composed of a conductive metal sheet and small light bulbs. The small light bulbs are fixedly installed and displayed on the outer wall of the engaging disc, and there are multiple groups of small light bulbs. The colors of the small light bulbs in different radius ranges on the engaging disc are different. The edge of the top wall of the first metal elastic sheet is provided with a rounded corner, and the edge of the top wall of the second metal elastic sheet is provided with a rounded corner. When the first metal elastic sheet and the second metal elastic sheet with the rounded corner structure are in contact with the power supply assembly and the display lamp assembly respectively, they slide in a staggered manner. After the first metal elastic sheet contacts the power supply assembly, it transfers electric energy to the second metal elastic sheet, and the second metal elastic sheet contacts the metal sheet in the display lamp assembly, and then transfers the electric energy to the small light bulbs through the metal sheet. After the small light bulbs are powered on, they become bright. The small light bulbs in different radius ranges adopt different colors. If the pressing depth of the forging round die is different, the lights of the small light bulbs within the corresponding radius will be different, so as to indicate whether the forging round die is installed in place.

[0018] Further, the top wall of the calibration sliding bracket is provided with balls, and the inserted clamping block of the disc is a three-dimensional rectangle.

[0019] Further, the trolley structure includes a frame, the bottom of the frame is provided with rollers, and the frame is provided with a handle.

[0020] Further, the forging round die includes an upper die and a bottom die. The upper die is pushed by a cylinder, and the bottom die is in contact and connected with the upper die.

[0021] Preferably, there are multiple groups of diameter sizes of the engaging disc. Different diameter sizes can be correspondingly selected according to the length of the bottom calibration bracket extending from the positioning device sleeve. The diameter size of the engaging disc is proportional to the moving length of the bottom calibration bracket.

[0022] The beneficial effects of a forging round die inner wall detection device provided by this solution are as follows:

[0023] (1) According to the laser emitted by the double-layer laser emitter, adjust the spatial height of the positioning device sleeve to make the center of the positioning device sleeve coincide with the center of the bottom die. Through the transmission of the ball screw assembly, clamp the front and back surfaces of the forging round die with the forging table clamping plate, so that the positioning device sleeve and the forging round die are relatively fixed. In order to reduce the probability of displacement of the positioning device sleeve caused by the downward pressing of the upper die, at the same time, select a suitable upper die detection device according to the specifications of the forging round die, drive the bottom calibration bracket to move through the chuck structure, and confirm the specifications of the forging round die according to the moving distance of the bottom calibration bracket;

[0024] (2) Increase the gravity at the bottom of the rotating clamping plate to make it perpendicular to the horizontal plane and parallel to the scale needle. Ensure that the bottom mold is installed on a relatively stable ground. Utilize the displacement caused by the upper mold pressing down on the calibration sliding bracket. When the metal elastic sheet 1 and the metal elastic sheet 2 in the calibration sliding bracket are in contact with the power supply component and the display lamp component respectively for electrical conduction, the position where the small light bulbs light up within different radii can be determined according to the movement of the calibration sliding bracket. When all the small light bulbs light up within a certain radius range, it indicates that the installation of the upper mold meets the standard. If there are small light bulbs lighting up within non - the same radius range, the spatial position of the upper mold needs to be adjusted. Brief Description of the Drawings

The calibration sliding bracket 41 slides up and down along the calibration bracket slot 40. A spring is connected between the calibration bracket slot 40 and the calibration sliding bracket 41. The power supply component 42 is fixedly installed on one side of the side wall of the calibration bracket slot 40, and the display lamp component 43 is fixedly installed on the other side of the side wall of the calibration bracket slot 40.

[0049] The display lamp component 43 is composed of a conductive metal sheet and a small light bulb. The edge of the top wall of the first metal elastic sheet 44 is provided with a rounded corner, and the edge of the top wall of the second metal elastic sheet 46 is provided with a rounded corner.

[0050] The top wall of the calibration sliding bracket 41 is provided with a ball, and the disk insertion block 34 is set as a three-dimensional rectangle.

[0051] The trolley structure 3 includes a vehicle frame 47. Wheels are provided at the bottom of the vehicle frame 47, and a handle is provided on the vehicle frame 47.

[0052] The forging circular die 1 includes 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 and connected with the upper die 48.

[0053] During specific use, after installing the upper die 48 and the bottom die 49 in the factory area respectively, the forging round die 1 needs to be calibrated. An uncalibrated forging round die 1 has a risk of damage during forging; drive the trolley structure 3 to move the die detection device 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 one 9 rotates, and the nut one 10 slides along the ball screw one 9. While dragging the positioning device sleeve 12 to move up and down, the laser trajectory emitted by the double-layer laser emitter 13 is adjusted in the 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 both groups of double-layer laser emitters 13 on both sides of the positioning device sleeve 12 meet the above requirements to ensure that the center of the positioning device sleeve 12 coincides with the center of the bottom die 49; in order to fix the positioning device sleeve 12 relative to the forging round die 1, mechanical equipment is needed to fix the overall structure of the detection device to prevent the detection device from shifting when the upper die 48 contacts the bottom die 49. Therefore, rotate the ball screw two 15 to drive the screw slot three 17 to move horizontally, so that the forging table clamping plate 20 moves to a position convenient for clamping both sides of the bottom die 49. Rotate the ball screw three 18 to make the forging table clamping plate 20 continue to displace. The two groups of forging table clamping plates 20 on the same side first separate and then move towards the middle position to reduce the distance between them and the bottom die 49, thereby fixing the positioning device sleeve 12 relative to the bottom die 49 in a mechanically clamped manner; afterwards, in order to prevent the bottom of the detection device from dropping when the upper die 48 presses down, and to prevent it from deforming due to multiple presses of the upper die 48 and affecting the accuracy, drive the embedded chuck 21 to rotate. While the turbine convex rib 25 rotates, make the support clamping plate 27 slide along the turbine convex rib 25, and the position of the bottom calibration support 26 changes. However, the bottom calibration support 26 is limited by the structural characteristics of the convex rib straight slot 29, prompting the bottom calibration support 26 to slide along the direction of the convex rib straight slot 29. The length that the bottom calibration support 26 extends from the positioning device sleeve 12 can be marked by the scale on the bottom calibration support 26, and the length of the movement of the bottom calibration support 26 is used to determine which size of the engaging disc 32 to select; after inserting the engaging disc 32 into the disc insertion slot 33 through the disc insertion block 34, rotate the clamping plate 38 to swing on the central support 35 between the engaging disc 32 and the symmetric limiting 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 die fixing device 5, and the bottom die support device 6, the scale needle 37 and the bottom counterweight 39 should be in a parallel positional 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 position of the detection device needs to be readjusted;When the scale needle 37 and the bottom counterweight 39 are parallel to each other when viewed from the front, control the upper die 48 to slowly press downwards. The arc-shaped inner wall of the upper die 48 contacts the calibration sliding bracket 41 on the rotary clamping plate 38. The calibration sliding bracket 41 slides into the calibration bracket slot 40 under the pressing of the upper die 48. If during this process, the pressing of the calibration sliding bracket 41 by the upper die 48 causes the rotary clamping plate 38 to deflect, it directly proves that the upper die 48 and the bottom die 49 are not aligned, and the offset distance between the upper and lower dies is too large; when the calibration sliding bracket 41 can enter the calibration bracket slot 40 without shaking of the rotary clamping plate 38, and when the first metal elastic piece 44 and the second metal elastic piece 46 are in contact with the power supply assembly 42 and the display lamp assembly 43 respectively, the electric energy is transferred from the power supply assembly 42 to the display lamp assembly 43. When multiple groups of small light bulbs within the same radius light up, it proves that the upper die 48 and the bottom die 49 are aligned vertically, and the installation error of the upper die 48 is small. If the small light bulbs within the same radius do not all light up, but the light bulbs within another outer diameter range light up, 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 adjusted again.

[0054] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0055] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
