Description

Technical Field

[0001] This utility model relates to the field of steel strip adhesive peeling technology, and in particular to a heatable steel strip adhesive peeling tool. Background Technology

[0002] Steel-reinforced polyethylene spiral corrugated pipe, also known as steel-reinforced polyethylene spiral corrugated pipe, is a type of composite pipe. It consists of a steel reinforcement layer, inner and outer polyethylene layers, and a resin layer. The inner and outer polyethylene layers are adhered to the inner and outer sides of the steel reinforcement layer via the resin layer. The steel reinforcement layer is made of high-strength steel strip spirally wound into a corrugated shape, providing compressive strength.

[0003] After mass production of the steel strip tubing, samples must be taken for peel strength testing of its outer layer. During testing, a cutting tool is used to make a circumferential cut along the crest of the specimen, creating a polyethylene strip with a width of 20mm-30mm and a length of at least 100mm. The cut should penetrate and peel off the resin layer. A force gauge is then used to clamp the cut polyethylene strip and resin layer, and the peel strength test can begin. The polyethylene strip and resin layer constitute the adhesive layer of the steel strip.

[0004] The traditional method of cutting open the steel strip involves using a utility knife to peel off the polyethylene layer. However, since the polyethylene layer is bonded to the outer wall of the steel strip with resin, and the resin has a strong adhesive force, workers need to spend a lot of time scraping off the resin in the corresponding areas, which results in high labor intensity. Utility Model Content

[0005] In view of the above problems, this utility model provides a heatable steel strip adhesive peeling tool.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This application discloses a heatable steel strip adhesive peeling tool, referring to... Figure 1 , Figure 2 and Figure 3 It includes a handle 1, a blade head 2 and a heating element 3. One end of the handle 1 has a first groove for inserting and engaging with the blade head 2. The heating element 3 is disposed inside the handle 1. One end of the blade head 2 has a second groove for inserting and engaging with the heating element 3. A connecting member 4 is provided between the handle 1 and the blade head 2.

[0023] In this embodiment, the blade head 2 is made of a high thermal conductivity alloy material (such as copper-based composite material), the handle 1 is made of a heat-insulating material (such as ceramic fiber), and the heating core 3 is an electric heating rod. A power supply (not shown in the figure) for providing power to the heating rod is installed inside the handle. When the operator turns on the power, the heating core 3 heats the blade head 2. After the operator uses the heated blade head 2 to cut open the polyethylene layer strip, the resin melts, making the peeling process more convenient. This reduces the labor intensity of the operator.

[0024] Reference Figure 4 and Figure 5 The connector 4 includes a pin 41. The side walls of the handle 1 and the head 2 are provided with limiting holes 5 of a size that are adapted to the pin 41. The pin 41 is movably inserted into the two limiting holes 5. The handle 1 is equipped with a first limiting member for preventing the pin 41 from sliding out of the limiting holes 5.

[0025] In this embodiment, the pin 41 is inserted into the limiting hole 5 on the handle 1 and the cutter head 2 to prevent the cutter head 2 from slipping off the handle 1. The operator can remove the pin 41 to remove the cutter head 2 and replace it. When removing the cutter head 2, the heating element 3 is also exposed for repair or replacement.

[0026] Specifically, the first limiting member includes a limiting block 6, which is slidably disposed in the tool holder 1 in a direction parallel to the axial direction of the tool holder 1. A groove 7 is provided on the inner wall of the limiting hole 5 on the tool holder 1 for the limiting block 6 to slide. A flat opening 411 is provided on the outer wall of the pin 41 for inserting and engaging with the limiting block 6. An elastic member 8 is provided in the groove 7 for driving the limiting block 6 to move away from the bottom wall of the groove 7.

[0027] In this embodiment, the operator can rotate the pin 41 within the limiting hole 5 to drive the limiting block 6 into the slide groove 7, and then pull out the pin 41. The elastic element 8 includes a spring, which is disposed in the slide groove 7, and both ends of the spring are respectively connected to the limiting block 6 and the bottom wall of the slide groove 7.

[0028] Furthermore, a sleeve 9 for shielding the cutter head 2 is coaxially and movably disposed on the outer wall of the tool holder 1. One end of the sleeve 9 is provided with a clearance opening 91 for the cutter head 2 to pass through. A second limiting member for restricting the movement of the sleeve 9 relative to the tool holder 1 is provided on the outer wall of the tool holder 1.

[0029] In this embodiment of the application, after the tool is used up, the worker can move the sleeve 9 to cover the blade 2 in order to avoid being accidentally injured by the blade 2.

[0030] Specifically, the second limiting member includes an external thread section 10 provided on the outer wall of the tool holder 1, and an internal thread section provided on the inner wall of the sleeve 9 for matching the external thread section 10.

[0031] In this embodiment, the operator can move the sleeve 9 relative to the handle 1 by rotating it.

[0032] Furthermore, a hand guard 20 is fitted onto one end of the sleeve 9.

[0033] In this embodiment, the hand guard 20 may be made of rubber, which can improve the safety of workers when using tools.

[0034] Furthermore, a hammer head 30 is detachably connected to the end of the handle 1 away from the blade head 2.

[0035] In this embodiment, the hammer head 30 is made of metal and has an insertion groove for engaging with the handle 1. Different types of steel strips use different resin materials, resulting in varying bond strengths. When the cutter head 2 encounters a high-strength bonded area, the operator can use other tools to strike the hammer head 30 to peel off the resin.

[0036] The implementation principle of the heatable steel strip adhesive peeling tool in this application embodiment is as follows: When the operator turns on the power, the heating core 3 heats the cutting head 2. After the operator uses the heated cutting head 2 to cut open the polyethylene strip, the resin melts, making the peeling process more convenient. This reduces the labor intensity of the operator.
