Description

Technical Field

[0001] The present application relates to the technical field of mechanical tools, and in particular to a pointed hammer for MAG welding quality inspection. Background Art

[0002] MAG welding is a kind of mixed gas shielded arc welding. It is a mixed gas shielded arc welding with a small amount of oxidizing gas (oxygen, carbon dioxide or a mixed gas) added to argon gas. It belongs to the melting welding method using arc as heat source. At present, MAG welding is widely used in locomotive manufacturing, shipbuilding, automobile manufacturing, coal mining machinery manufacturing and other fields. It is suitable for welding thin low-carbon steel, low-alloy steel, low-alloy high-strength steel plate, etc.

[0003] In the actual production process, MAG welding may produce cold welds due to improper operation and other reasons. However, such problems cannot be discovered by on-site visual inspection and can only be achieved by special non-destructive inspection methods, such as ultrasonic weld flaw detection or X-ray weld flaw detection. However, these methods are costly and not easy to operate, and are not suitable for daily MAG welding quality inspection. Summary of the invention

[0004] The embodiment of the present application provides a pointed hammer for detecting the welding quality of MAG welding, so as to solve the problem of the inconvenience in detecting the welding quality of MAG welding in the related art.

[0005] The embodiment of the present application provides a pointed hammer for MAG welding quality inspection, comprising:

[0006] A hammer head comprises a hammer body and a pointed head detachably connected to the hammer body.

[0007] In some embodiments, the pointed portion is made of 65# manganese steel, and the hammer body is made of 45# steel.

[0008] In some embodiments, a hammer handle is further included, wherein the hammer handle is fixedly connected to the hammer body, and an end of the hammer handle is bent toward the side where the pointed portion is located.

[0009] In some embodiments, a screw structure is provided on one side of the pointed portion close to the hammer body portion, and a threaded hole matching the screw structure is provided on the hammer body portion.

[0010] In some embodiments, the pointed portion is bent toward the direction of the hammer handle.

[0011] In some embodiments, the outer wall of the end of the hammer handle is circumferentially provided with anti-slip lines.

[0012] In some embodiments, the outer wall of the hammer handle is provided with an arc-shaped groove for gripping.

[0013] In some embodiments, the hammer handle sleeve is provided with a silicone protective sleeve.

[0014] In some embodiments, an arc chamfer is provided at an edge of the hammer body portion away from one end of the pointed portion.

[0015] In some embodiments, the radius of the tip end is in the range of 1.5 mm to 2.5 mm.

[0016] The beneficial effects of the technical solution provided by this application include:

[0017] An embodiment of the present application provides a pointed hammer for MAG welding quality inspection, including a hammer head, wherein the hammer head includes a hammer body and a pointed head detachably connected to the hammer body.

[0018] In actual use, the pointed hammer of the present application includes a hammer head, and the hammer head includes a pointed head. The pointed head of the pointed hammer is used to knock into the weld and the base material of the MAG weld, and then the pointed hammer is shaken. If the weld leaves the base material, it can be concluded that this is a cold weld and the weld is not fully penetrated. It can be judged that the welding quality is not up to standard. If this situation does not occur, it can be judged that the welding quality is qualified. The pointed head has a small diameter and is relatively sharp, so it can be easily inserted into the weld, which is convenient for testing the welding quality. In addition, the diameter of the pointed head is small, and the holes left after the inspection can be repaired, which will not cause damage to the product quality and meet the non-destructive inspection standards.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] The embodiment of the present application provides a pointed hammer for detecting the welding quality of MAG welding, which can solve the problem of the inconvenience in detecting the welding quality of MAG welding in the related art.

[0027] See also Figure 1 As shown, an embodiment of the present application provides a pointed hammer for MAG welding quality inspection, including a hammer head 1 , wherein the hammer head 1 includes a hammer body 12 and a pointed head 11 detachably connected to the hammer body 12 .

[0028] In actual use, the pointed hammer of the present application includes a hammer head 1, and the hammer head 1 includes a pointed head 11. The pointed head 11 of the pointed hammer is used to knock into the weld and the base material of the MAG weld, and then the pointed hammer is shaken. If the weld leaves the base material, it can be concluded that this is a cold weld and the weld is not penetrated. It can be judged that the welding quality is not up to standard. If this situation does not occur, it can be judged that the welding quality is qualified. The pointed head 11 has a small diameter and is relatively sharp, so it can be easily inserted into the weld, which is convenient for testing the welding quality. In addition, the pointed head 11 has a small diameter, and the holes left after the inspection can be repaired, which will not cause damage to the product quality and meet the non-destructive inspection standards. The hammer head 1 of the present application also includes a hammer body 12. During use, the hammer body 12 is used to ensure the weight of the hammer itself and facilitate the hammering of the pointed head 11. The pointed head 11 is detachably connected to the hammer body 12. This arrangement can facilitate the replacement of the pointed head 11. When the pointed head 11 is worn out due to long-term use, the pointed head 11 can be removed and replaced separately, thereby ensuring the quality of use while reducing the cost of replacement.

[0029] In some optional embodiments, the material of the pointed portion 11 is 65# manganese steel, and the material of the hammer portion 12 is 45# steel. The material of the hammer portion 12 is 45# steel. Since the hammer portion 12 does not directly contact the weld, the material of the hammer portion 12 can be 45# steel to ensure structural strength. The material of the pointed portion 11 is 65# manganese steel. Compared with 45# steel, 65# manganese steel has higher tensile and bending strength. At the same time, manganese has the function of increasing metal strength. During detection, it can ensure that the pointed portion 11 is smoothly inserted into the weld, thereby improving the convenience and reliability of detection. The material of the hammer portion 12 can be 45# steel. Although the strength of 45# steel is slightly weaker than that of 65# manganese steel, the hammer portion 12 will not directly contact the weld, which can save costs while ensuring a certain structural strength.

[0030] In some optional embodiments, such as Figure 2 and Figure 3 As shown, a screw structure is provided on one side of the pointed portion 11 close to the hammer body 12, and a threaded hole matching the screw structure is provided on the hammer body 12. The threaded connection makes it easy to fix and disassemble the pointed portion 11 and the hammer body 12. When the pointed portion 11 is used to hammer the weld and the base material multiple times, that is, after multiple tests are completed, the pointed portion 11 will inevitably wear out, and the sharpness of the pointed portion 11 will continue to decrease, affecting subsequent testing work. At this time, the pointed portion 11 can be replaced alone without replacing the entire hammer, which can save costs while ensuring the continued normal use of the hammer.

[0031] In some optional embodiments, such as Figure 1 As shown, it also includes a hammer handle 2, which is fixedly connected to the hammer body 12, and the end of the hammer handle 2 is bent toward the side where the pointed head 11 is located. The end of the hammer handle 2 is bent toward the side where the pointed head 11 is located, that is, the hammer handle 2 is arranged in a certain arc shape. Since the parent material is usually located in a horizontal plane when the welding quality is detected, it is usually necessary to hammer the hammer into the weld at a certain angle. This arrangement can facilitate the adjustment of the hammer angle, and facilitate the use of the pointed head 11 to hammer into the weld to detect and judge the welding quality. In some optional embodiments, the pointed head 11 is arranged in a curved shape toward the direction where the hammer handle 2 is located. In this arrangement, the pointed head 11 is arranged in a curved shape at a certain angle toward the direction where the hammer handle 2 is located, so that when hammering, the pointed head 11 can be smoothly knocked into between the weld and the parent material.

[0032] In some optional embodiments, the outer wall of the end of the hammer handle 2 is circumferentially provided with anti-skid patterns, which can prevent hand slippage when swinging the hammer handle 2, thereby ensuring reliability and safety in use.

[0033] In actual use, the hammer handle 2 can be covered with a silicone protective sleeve, which is convenient for holding and protecting the user's hands. In use, the outer wall of the hammer handle 2 is provided with an arc groove for holding, which is convenient for gripping.

[0034] In some optional embodiments, an arc chamfer is provided at the edge of the hammer body 12 away from the pointed portion 11. The arc chamfer can prevent the hammer body 12 from scratching and damaging external objects when the hammer is placed.

[0035] In some optional embodiments, the radius of the tip 11 is in the range of 1.5 mm to 2.5 mm, which can ensure that the tip 11 has a certain sharpness without causing serious damage to the weld due to being too sharp, and can prevent accidental injury to the user.

[0036] In summary, the pointed hammer for MAG welding quality inspection of the present application includes a hammer head 1, and the hammer head 1 includes a hammer body 12 and a pointed head 11 detachably connected to the hammer body 12. The pointed head 11 of the pointed hammer is used to knock into the weld and the base material of the MAG weld, and then the pointed hammer is shaken. If the weld leaves the base material, it can be concluded that this is a cold weld and the weld is not penetrated. It can be judged that the welding quality is not up to standard. If this situation does not occur, it can be judged that the welding quality is qualified. Since the pointed head 11 has a small diameter and is relatively sharp, it can be easily inserted into the weld, which is convenient for detecting the welding quality. In addition, the pointed head 11 has a small diameter, and the holes left after the inspection can be repaired, which will not cause damage to the product quality and meet the non-destructive inspection standards. The hammer head 1 of the present application also includes a hammer body 12. During use, the hammer body 12 is used to ensure the weight of the hammer itself and facilitate the hammering of the pointed head 11. The pointed head 11 is detachably connected to the hammer body 12. This arrangement can facilitate the replacement of the pointed head 11. When the pointed head 11 is worn out due to long-term use, the pointed head 11 can be removed and replaced separately, thereby ensuring the quality of use while reducing the cost of replacement.

[0037] The pointed part 11 is made of No. 65 manganese steel, and the hammer part 12 is made of No. 45 steel. The hammer part 12 is made of No. 45 steel. Since the hammer part 12 does not directly contact the weld, the hammer part 12 can be made of No. 45 steel to ensure structural strength. The pointed part 11 is made of No. 65 manganese steel. Compared with No. 45 steel, No. 65 manganese steel has higher tensile and bending strength. At the same time, manganese has the function of increasing metal strength. During detection, it can ensure that the pointed part 11 is smoothly inserted into the weld, thereby improving the convenience and reliability of detection. The hammer part 12 can be made of No. 45 steel. Although the strength of No. 45 steel is slightly weaker than that of No. 65 manganese steel, the hammer part 12 will not directly contact the weld, which can save costs while ensuring a certain structural strength.

[0038] A screw structure is provided on one side of the pointed portion 11 close to the hammer body 12, and a threaded hole matching the screw structure is provided on the hammer body 12. The threaded connection is convenient for fixing and disassembling the pointed portion 11 and the hammer body 12. After completing multiple tests, the pointed portion 11 will inevitably wear out, and the sharpness of the pointed portion 11 will continue to decrease, affecting subsequent testing work. At this time, the pointed portion 11 can be replaced alone without replacing the entire hammer, which can save costs while ensuring the continued normal use of the hammer. The pointed hammer of the present application also includes a hammer handle 2, which is fixedly connected to the hammer body 12, and the end of the hammer handle 2 is bent toward the side where the pointed portion 11 is located. The end of the hammer handle 2 is bent toward the side where the pointed portion 11 is located, that is, the hammer handle 2 is arranged in a certain arc shape. Since the parent material is usually located in a horizontal plane when testing the welding quality, it is usually necessary to hammer the hammer into the weld at a certain angle. This setting can facilitate the adjustment of the hammer angle, and facilitate the use of the pointed head 11 to hammer into the weld to detect and judge the welding quality. In some optional embodiments, the pointed head 11 is bent toward the direction of the hammer handle 2. In this setting, the pointed head 11 is bent at a certain angle toward the direction of the hammer handle 2, which facilitates the pointed head 11 to be smoothly knocked into between the weld and the parent material when hammering.

[0039] The outer wall of the end of the hammer handle 2 is provided with anti-skid lines in the circumferential direction, which can prevent the hand from slipping when swinging the hammer handle 2, and ensure the reliability and safety of use. The hammer handle 2 can be covered with a silicone protective cover, which can be easy to hold and protect the user's hands. In use, the outer wall of the hammer handle 2 is provided with an arc groove for holding, which is convenient for gripping.
