Description

Technical Field

[0001] This invention relates to the field of punching die inspection technology, specifically a radiographic testing device for punching die inspection. Background Technology

[0002] A punching die is a type of die used for punching and cutting materials such as sheet metal and strip. It features high production efficiency, wide applicability, and is widely used in industries such as automobiles, electronics, electrical appliances, and machinery.

[0003] Radiographic testing is a non-destructive testing method that utilizes the property of rays to penetrate objects and develop the internal structure of the object on a photosensitive material during the penetration process to detect internal defects. In the process of inspecting the sidewalls of tubular punching dies, radiographic testing devices are used for flaw detection. However, existing radiographic testing devices cannot tightly fit the film bag containing the photosensitive film to the tubular punching die, resulting in poor film development and hindering the improvement of the accuracy of flaw detection in punching dies. Therefore, a radiographic testing device for punching die inspection is provided to solve the above problems. Summary of the Invention

[0010] As an improvement of the present invention: the extrusion spreading assembly includes an extension rod that is horizontally slidably mounted on the extension box, a fixed sleeve that is fixed on the sleeve is sleeved on the extension rod, a sliding column that slides into the fixed sleeve is fixed on the connecting plate, a connecting block is fixed at the end of the extension rod away from the fixed sleeve, a spring ring is fixed between the connecting block and the fixed sleeve, and a roller pressing assembly is mounted on the connecting block.

[0011] As an improvement of the present invention: the roller pressing assembly includes a pair of connecting shafts rotatably mounted on the connecting block, a rotating plate is fixed on the connecting shaft, a pressure roller opposite to the flexible plate is rotatably mounted on the end of the rotating plate away from the connecting shaft, a fixed plate is fixed on the connecting shaft, and a torsion spring II sleeved on the connecting shaft is fixed between the fixed plate and the connecting block.

[0012] As an improvement of the present invention: a connecting frame is slidably installed on the abutting arc block, a retaining tube is fixed on the connecting frame, and a traction spring I is fixed between the retaining tube and the abutting arc block.

[0013] As an improvement of the present invention: the snap-fit ​​assembly includes a post fixed on a flexible plate, the post extending into the snap-fit ​​tube, and a trapezoidal snap-fit ​​block adapted to snap-fit ​​the post is slidably installed in the snap-fit ​​tube. A traction spring II is fixed between the trapezoidal snap-fit ​​block and the snap-fit ​​tube, and the sliding direction of the trapezoidal snap-fit ​​block is perpendicular to that of the post.

[0014] As an improvement of the present invention: the locking assembly includes a sleeve block rotatably mounted on a support base, a torsion spring I fixed between the sleeve block and the support base, a clamping frame slidably mounted inside the sleeve block opposite to the outer wall of the punching die, a push spring fixed between the clamping frame and the sleeve block, and a push frame vertically corresponding to the sleeve block fixed on the side wall of the lifting ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention uses a stepping rotary drive assembly to drive the X-ray source to rotate at equal angles, allowing the X-ray source to face multiple film bags one by one. This enables individual flaw detection operations on different positions around the punching die. After the abutting arc block presses against the side wall of the punching die, the sliding column pushes the extension rod, causing the connecting block to slide. This allows the pressure roller in the rolling assembly to roll the flexible plate and film bags under the drive of the rotating plate. This effectively ensures that the film, after deformation, adheres tightly to the outer wall of the punching die along with the flexible plate and film bags, greatly improving the X-ray imaging effect of the punching die. The accuracy and ease of operation of the flaw detection of the punching die are significantly improved.

[0018] 2. In this invention, before the film sleeve is tightly attached to the outer wall of the punching die, the downward movement of the pusher can push the sleeve block to rotate, so that multiple clamping frames can abut and clamp the punching die for positioning. As the pusher spring is deformed and compressed, the punching die has a vertical downward displacement, and the end of the punching die can abut against the chassis. This realizes the synchronous operation of lateral clamping and bottom positioning of the punching die, improves the clamping efficiency and stability of the punching die, and ensures the accuracy of radiographic testing.

Detailed Implementation

[0032] The technical solution of the present invention will be further described in detail below with reference to specific embodiments:

[0033] First Embodiment

[0034] Please see the appendix Figure 1 - Appendix Figure 12A radiographic testing device for punching dies includes a frame 1, a base 14 fixed on the frame 1, a plurality of auxiliary wedges 15 for bottom limiting of the punching die 20 radially slidably mounted on the base 14, a threaded post 21 mounted on the frame 1, a lifting frame 7 vertically slidably connected to the threaded post 21, a radiographic source 6 extending into the punching die 20 mounted on the lifting frame 7, a stepping rotation drive assembly for driving the radiographic source 6 to rotate at equal angles mounted on the lifting frame 7, a sleeve 5 sleeved on the punching die 20 fixed on the lifting frame 7, a lifting ring 27 sleeved on the sleeve 5, and an adjustment assembly for driving the lifting ring 27 to slide axially relative to the sleeve 5 mounted on the frame 1. A number of evenly distributed abutment arc blocks 23 are radially slidably installed on the side wall of the tube 5. The abutment arc blocks 23 are hollow structures. A transmission component for driving the abutment arc blocks 23 to move toward the punching die 20 is installed between the lifting ring 27 and the sleeve 5. A flexible plate 34 is installed on the side of the abutment arc block 23 opposite to the punching die 20 through a snap-fit ​​component. A film bag 33 opposite to the punching die 20 is fixed on the flexible plate 34. An extension box 24 is fixed on the abutment arc block 23. An extrusion spreading component for pushing the flexible plate 34 is installed inside the extension box 24 and the abutment arc block 23. A number of support seats 54 are fixed on the frame 1. A locking component for abutting the side wall of the punching die 20 is rotatably installed on the support seats 54.

[0035] The rotation of the threaded column 21 drives the lifting frame 7 to move vertically downward, allowing the X-ray source 6 to move downward and extend into the punching die 20. At the same time, the lifting frame 7 drives the sleeve 5 to move downward synchronously and fit over the punching die 20. The X-ray source 6 and the abutting arc block 23 correspond radially along the punching die 20, that is, the X-ray source 6 corresponds to the film stored in the film bag 33.

[0036] The stepping rotary drive assembly of this device includes a motor II3 fixed to the top of the lifting frame 7, a vertically arranged steering shaft 8 rotatably mounted on the lifting frame 7, a radiation source 6 fixed to the lower end of the steering shaft 8, a transmission gear 30 coaxially fixed to the top of the steering shaft 8, and an incomplete gear 22 coaxially fixed to the output shaft of the motor II3, which intermittently meshes with the transmission gear 30.

[0037] By controlling motor II3, the incomplete gear 22 can be driven to rotate one revolution. Each revolution of the incomplete gear 22 drives the transmission gear 30 to rotate a certain angle. At this time, the steering shaft 8 drives the X-ray source 6 to rotate a certain angle, thereby enabling the X-ray source 6 to correspond to different films one by one. The X-ray source 6 and the punching die 20 at different circumferential positions can be accurately corresponded one by one for flaw detection, and the flaw detection operation efficiency is greatly improved.

[0038] The adjustment assembly includes a threaded collar 9 rotatably mounted on the lifting ring 27, which is threaded onto the sleeve 5. A guide block 50 is fixed to the inner wall of the lifting ring 27 and axially slidably mounted on the outer wall of the sleeve 5. The transmission assembly includes a slide rod 35 that slides through the side wall of the sleeve 5. One end of the slide rod 35 is fixed to the abutting arc block 23, and the other end of the slide rod 35 is fixed to a baffle 37. A connecting plate 18 is sleeved on the slide rod 35. A connecting spring 25 is fixed between the connecting plate 18 and the sleeve 5. The connecting plate 18 abuts against the baffle 37. A pushing wedge block 17 that is vertically corresponding to the connecting plate 18 is fixed on the lifting ring 27.

[0039] In addition, the extrusion spreading assembly includes an extension rod 43 that is horizontally slidably mounted on the extension box 24. A fixed sleeve 26 that is fixed on the sleeve 5 is sleeved on the extension rod 43. A sliding column 36 that slides into the fixed sleeve 26 is fixed on the connecting plate 18. A connecting block 42 is fixed at one end of the extension rod 43 away from the fixed sleeve 26. A spring ring 45 is fixed between the connecting block 42 and the fixed sleeve 26. A roller pressing assembly is mounted on the connecting block 42.

[0040] When the threaded collar 9 rotates, it can drive the lifting ring 27 to move vertically. At this time, the pushing wedge block 17 moves vertically downward and pushes the connecting plate 18. The connecting plate 18 drives the sliding column 36 to slide relative to the fixed sleeve 26. After the sliding column 36 abuts against the extension rod 43, the connecting block 42 drives the extension box 24 and the abutting arc block 23 to move towards the punching die 20 through the spring ring 45. Subsequently, the abutting arc block 23 drives the flexible plate 34 and the film bag 33 to abut against the outer wall of the punching die 20, effectively ensuring the accuracy of radiographic testing.

[0041] The roller pressing assembly includes a pair of connecting shafts 53 rotatably mounted on a connecting block 42. A rotating plate 41 is fixed on the connecting shafts 53. A pressure roller 44, opposite to the flexible plate 34, is rotatably mounted on the end of the rotating plate 41 away from the connecting shafts 53. A fixing plate 52 is fixed on the connecting shafts 53. A torsion spring II 51, sleeved on the connecting shafts 53, is fixed between the fixing plate 52 and the connecting block 42. A connecting frame 29 is slidably mounted on the abutting arc block 23. A retaining tube 38 is fixed on the connecting frame 29. A traction spring I 13 is fixed between the retaining tube 38 and the abutting arc block 23.

[0042] With the above settings, after the abutting arc block 23 drives the flexible plate 34 and the film sleeve 33 to press against the outer wall of the punching die 20, the extension rod 43 drives the connecting block 42 to slide toward the punching die 20. At this time, the two pressure rollers 44 abut against the flexible plate 34 and roll toward both sides respectively. At this time, the rotating plate 41 rotates, realizing the roller pressing effect of the pressure rollers 44 on the flexible plate 34 and the film sleeve 33, so that the film sleeve 33 and the inner film can be spread and deformed, ensuring that the film sleeve 33 can be pressed tightly against the outer wall of the punching die 20, which greatly improves the accuracy of radiographic testing.

[0043] Second Embodiment

[0044] Please see the appendix Figure 1 - Appendix Figure 12 Based on the first embodiment, the snap-fit ​​assembly includes a post 55 fixed on the flexible plate 34, the post 55 extending into the snap-fit ​​tube 38, a trapezoidal snap-fit ​​block 39 adapted to snap-fit ​​the post 55 is slidably installed in the snap-fit ​​tube 38, a traction spring II 40 is fixed between the trapezoidal snap-fit ​​block 39 and the snap-fit ​​tube 38, and the sliding direction of the trapezoidal snap-fit ​​block 39 is perpendicular to that of the post 55.

[0045] The inserted post 55 can be inserted into the clamping tube 38. The trapezoidal clamping block 39 is clamped and matched with the inserted post 55 under the pushing action of the traction spring II 40, realizing the detachable installation of the flexible plate 34 and the connecting frame 29. This greatly facilitates the connection and separation of the film bag 33 and the abutting arc block 23, and makes it convenient for the installation and removal of the film before and after development.

[0046] In addition, the locking assembly of this device includes a sleeve block 19 rotatably mounted on the support base 54, a torsion spring I32 fixed between the sleeve block 19 and the support base 54, a clamping frame 28 slidably mounted inside the sleeve block 19 opposite to the outer wall of the punching die 20, a push spring 31 fixed between the clamping frame 28 and the sleeve block 19, and a push frame 16 vertically corresponding to the sleeve block 19 fixed on the side wall of the lifting ring 27.

[0047] Before the abutting arc block 23 drives the film sleeve 33 on it to abut and fit against the outer wall of the punching die 20, the lifting ring 27 drives the pushing frame 16 to move vertically downward. At this time, the pushing frame 16 pushes the sleeve block 19 to rotate toward the punching die 20. At this time, the clamping frame 28 rotates toward the punching die 20 and abuts and clamps it. During this process, the clamping frame 28 slides relative to the sleeve block 19, and the pushing spring 31 is elastically compressed. During the clamping process of the clamping frame 28, the punching die 20 is driven to move vertically downward, so that the lower end of the punching die 20 abuts against the chassis 14. The punching die 20 is stably limited, and the stability of the radiographic testing process of the punching die 20 is significantly improved, effectively ensuring the accuracy of radiographic testing.

[0048] Additionally, a motor I2 is fixed on the frame 1, and a drive shaft 49 is driven and connected to the motor I2. A rotating sleeve 46 is slidably sleeved on the drive shaft 49. A retaining strip 48 fixed on the drive shaft 49 is slidably embedded in the inner wall of the rotating sleeve 46. Gears I11 and II12 are fixedly sleeved on the rotating sleeve 46. An external gear ring 10 that meshes with gear I11 is fixedly sleeved on the threaded collar 9. A gear III56 that meshes with gear II12 is fixedly sleeved on the threaded column 21. A cylinder 4 is fixed on the frame 1. A switching frame 47 is fixed to the telescopic end of the cylinder 4. The rotating sleeve 46 is rotatably mounted on the switching frame 47.

[0049] The cylinder 4 drives the rotating sleeve 46 to move vertically, so that when gear II 12 moves to mesh with gear III 56, gear I 11 does not mesh with the outer gear ring 10. At this time, the lifting frame 7 can be adjusted to move up and down, that is, the axial adjustment of the flaw detection position can be realized. After the position of the lifting frame 7 is adjusted, the rotating sleeve 46 is moved by adjusting the movement, so that when gear I 11 meshes with the outer gear ring 10, gear II 12 does not mesh with gear III 56. At this time, the lifting ring 27 can be adjusted to move up and down.

[0050] In summary, this invention enables the X-ray source 6 to rotate at equal angles via a stepping rotary drive assembly, allowing the X-ray source 6 to face multiple film sleeves 33 one by one. This enables individual flaw detection operations on different circumferential positions of the punching die 20. Furthermore, after the abutting arc block 23 presses against the side wall of the punching die 20, the sliding column 36 pushes against the extension rod 43, causing the connecting block 42 to slide. This allows the pressure roller 44 in the rolling assembly to roll the flexible plate 34 and film sleeves 33 under the drive of the rotating plate 41. This effectively ensures that the film, after deformation, adheres tightly to the outer wall of the punching die 20 along with the flexible plate 34 and film sleeves 33, greatly improving the X-ray imaging effect of the punching die 20. Consequently, the flaw detection accuracy and ease of operation of the punching die 20 are significantly enhanced. Before the film sleeve 33 is tightly attached to the outer wall of the punching die 20, the pushing frame 16 moves down to push the sleeve block 19 to rotate, so that multiple clamping frames 28 can clamp and position the punching die 20. As the pushing spring 31 deforms and compresses, the punching die 20 has a vertical downward displacement, and the end of the punching die 20 can abut against the chassis 14. This realizes the synchronous operation of lateral clamping and bottom positioning of the punching die 20, improves the clamping efficiency and stability of the punching die 20, and ensures the accuracy of radiographic testing.
