Description

Technical Field

[0001] This utility model relates to the field of mold testing technology, specifically to a stamping die wear detection device. Background Technology

[0002] In the production of some parts, it is necessary to use a press to form them instead of traditional bending. In an automated stamping system, the mold is one of the most critical components. The quality of the mold directly affects the quality of the stamped parts. Since the mold will wear out after a long period of use, it is necessary to regularly inspect the wear of the mold and repair or replace it to ensure the production effect of the parts.

[0003] A search revealed that the Chinese patent "A Stamping Die Wear Detection Mechanism" (authorization announcement number CN209085570U) includes a top plate, a middle frame, an air box, a forming head, a first needle-shaped air duct, a second needle-shaped air duct, a first detection hole, a second detection hole, a pressure gauge, and an air inlet pipe. The device is placed directly above the mold to be tested. A connecting frame secures the mechanism to a press. The press moves the connecting frame downwards, and the connecting frame, via a spring, presses the middle frame, which is fixed to the top plate, against the mold. Compressed air is blown through the first and second needle-shaped air ducts to the side and bottom of the forming head. If there is wear in the mold cavity, there will inevitably be a gap between the worn area and the forming head. Compressed air can then enter the forming head cavity through the first or second detection hole, and the pressure gauge can detect the pressure value, thus determining the wear condition of the stamping die. The device has a simple structure and can directly detect the wear of the stamping die without disassembling it, effectively improving the efficiency and accuracy of die wear detection. However, the above method has the following drawbacks in actual use: although it can detect the wear of the die, it can only detect the overall wear of the die and cannot detect the wear of corresponding areas separately. It is not easy to know the wear of different parts of the die, which increases the difficulty of finding the repair area.

[0004] Based on this, the present invention designs a stamping die wear detection device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stamping die wear detection device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A stamping die wear detection device includes a copying head and a circular box disposed inside it. A set of needle-shaped air ducts are provided on the four horizontal sides and bottom of the circular box. Five sets of detection holes are opened inside the copying head. One end of each needle-shaped air duct extends into the corresponding detection hole. The device also includes five detection mechanisms, each located on the outside of the circular box and used to separately detect the wear of different areas of the die. Each detection mechanism includes a retaining box and two partitions. The retaining box is fixedly sleeved onto the outside of the needle-shaped air ducts and fixedly installed on the inner wall of the copying head. The opening of the retaining box faces the detection holes. The partitions are inserted into the inside of the retaining box and are offset from the needle-shaped air ducts.

[0008] Furthermore, the card box is provided with a set of uprights communicating with it, and the inside of the uprights is slidably connected with uprights extending to its outer side;

[0009] Furthermore, the outer side of the upright is provided with scale values, and one end of the upright is equipped with a piston plate that is slidably connected to the inner wall of the riser.

[0010] Furthermore, a U-shaped sealing gasket is embedded on the outer side of the partition, and the partition and the card box slide against each other.

[0011] Furthermore, a magnet is embedded at the bottom of the partition, and a metal block magnetically connected to the magnet is embedded in the inner bottom wall of the card box;

[0012] Furthermore, the U-shaped box is equipped with a bend tube for docking with a micro air pump, and a solenoid valve is provided on the outside of the bend tube;

[0013] Furthermore, a docking frame is provided on the top of the contouring head;

[0014] Furthermore, one end of the bottom riser extends to the inside of the U-shaped box, and there is space between the bottom of the U-shaped box and the inner bottom wall of the contour head for the bottom partition to move vertically.

[0015] Beneficial effects

[0016] 1. By setting up card boxes, card boxes at corresponding positions can be fitted onto the outside of needle-shaped air ducts in corresponding areas. During gas discharge, the amount of gas discharged from each side is discharged independently, allowing for independent single-sided detection of the mold and determining the degree of wear at different locations of the mold.

[0017] 2. By setting up partitions, the wear area on one side can be further subdivided to accurately identify the wear area, which facilitates targeted repair treatment later. Attached Figure Description

[0025] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4A stamping die wear detection device includes a profile head 100 and a circular box 200 disposed inside it. A set of needle-shaped air ducts 300 are provided on the four horizontal sides and bottom of the circular box 200. Five sets of detection holes 110 are opened inside the profile head 100. One end of each needle-shaped air duct 300 extends into the corresponding detection hole 110. The device also includes five detection mechanisms 400, which are disposed on the outside of the circular box 200 and used to detect the wear of different areas of the die separately. Each detection mechanism 400 includes a card box 410 and two partitions 420. The card box 410 is fixedly sleeved on the outside of the needle-shaped air ducts 300 and fixedly installed on the inner wall of the profile head 100. The opening of the card box 410 faces the detection hole 110. The partitions 420 are inserted into the inside of the card box 410 and are offset from the needle-shaped air ducts 300.

[0028] In this embodiment of the utility model, the contour head 100 is placed into the mold, and then external gas is introduced into the shaped box 200. When the corresponding side of the contour head 100 is in contact with the inside of the mold, it indicates that there is no wear in that area. If there is wear, the gas in the needle-shaped air duct 300 on the corresponding side will be discharged along the wear gap. Then the detection mechanism 400 can know the wear condition based on the amount of gas discharged.

[0029] In this embodiment of the utility model, a corresponding card box 410 is used to cover the needle-shaped air ducts 300 in the corresponding area. Then, a certain amount of gas is introduced into the corresponding set of needle-shaped air ducts 300. When there is wear in the area, the gas introduced into the needle-shaped air ducts 300 enters between the mold and the profiling head 100, and then enters the card box 410 along the corresponding detection hole 110 near the area. The degree of wear in the area can be determined by the amount of gas discharged from the card box 410.

[0030] It should be noted that when finer testing is required, the corresponding partition 420 can be attached to the inner bottom wall of the card box 410 before wear testing, so that the single card box 410 is divided into multiple testing areas to complete the wear testing of different areas.

[0031] A sealing plate can be installed on the mating side of the profiling head 100 and the mold to reduce wear between them, while improving airtightness during the inspection process and ensuring inspection accuracy.

[0032] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, a set of risers 411 communicating with the card box 410 are provided on the card box 410, and a riser 412 extending to the outside of the riser 411 is slidably connected inside the riser 411.

[0033] After the gas is introduced into the cartridge 410, the gas will push the upright 412 to slide inside the riser 411, so that the user can know the wear condition of the area based on the rise of the upright 412.

[0034] It should be noted that during separate monitoring, the corresponding uprights 412 will move accordingly based on the gas volume. When performing single-sided monitoring, due to the principle of air pressure balance, the upward amplitude of multiple uprights 412 on a single side is the same.

[0035] In this embodiment of the utility model, the outer side of the upright 412 is provided with scale values, and one end of the upright 412 is equipped with a piston plate that is slidably connected to the inner wall of the riser 411. The use of scale values ​​makes it easy for users to clearly know the rising range of the upright 412, and the wear degree of the area can be obtained from the change of scale values.

[0036] The piston plate is designed to ensure airtightness. When gas enters the riser 411, the gas drives the piston plate to move, causing the riser 412 to move accordingly.

[0037] In this embodiment of the utility model, a U-shaped sealing gasket 421 is embedded on the outer side of the partition 420. The partition 420 and the card box 410 slide against each other. By using the U-shaped sealing gasket 421, the gas separation effect of the partition 420 can be guaranteed and the occurrence of gas leakage can be reduced.

[0038] By using a friction sliding method, the frictional resistance between the partition 420 and the card box 410 can be used to stabilize the partition 420 after it is pulled, thus reducing the possibility of the partition 420 sliding unexpectedly due to its own weight.

[0039] In this embodiment of the utility model, a magnet is embedded at the bottom of the partition 420, and a metal block that is magnetically connected to the magnet is embedded in the inner bottom wall of the card box 410. After the partition 420 is inserted into place, it is magnetically attracted to the metal block at this time to ensure the stability of the partition 420.

[0040] In this embodiment of the utility model, a folded tube for connecting to a micro air pump is installed on the folded box 200. A solenoid valve is provided on the outside of the folded tube. An external micro air pump is connected to the folded tube. When performing a testing operation, the solenoid valve is opened, and a quantitative gas is then pressurized and delivered to the folded box 200.

[0041] In this embodiment of the utility model, the top of the profiling head 100 is provided with a docking frame, which is used to dock with the end of the press. Then, during the inspection operation, the press drives the profiling head 100 to dock with the mold.

[0042] In this embodiment of the utility model, one end of the bottom upright tube 411 extends to the inside of the U-shaped box 200. There is space between the bottom of the U-shaped box 200 and the inner bottom wall of the contour head 100 for the bottom partition 420 to move vertically. This allows the user to easily observe the rising range of the upright 412 in the corresponding area. At the same time, there is enough space when pulling the bottom partition 420 to reduce the occurrence of jamming.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
