Description

Technical Field

[0001] This invention belongs to the field of titanium alloy casting processing technology, specifically relating to a special tool for cleaning anti-acid paint after pickling titanium alloy castings. Background Technology

[0002] During the production and processing of titanium alloy castings, a pickling step is required. This involves applying an acid-resistant paint to specific areas of the titanium alloy casting surface before pickling. After pickling, the acid-resistant paint needs to be cleaned off. However, in existing technologies, the cleaning of the acid-resistant paint on the surface of titanium alloy castings after pickling is generally done manually by operators using heating. During the heating process after pickling, it is difficult to accurately control the surface temperature of the titanium alloy casting manually, which reduces the efficiency of cleaning the acid-resistant paint and lowers work efficiency. Therefore, this invention proposes a special tool for cleaning the acid-resistant paint on titanium alloy castings after pickling. Summary of the Invention

[0003] The purpose of this invention is to provide a special tool for cleaning anti-acid paint after pickling titanium alloy castings, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a special tool for cleaning anti-acid paint after pickling titanium alloy castings, including a hot air gun, a hot air outlet pipe at the front end of the hot air gun, a power cord at the rear end of the hot air gun, a scraper installed at the front end of the hot air gun relative to the bottom of the hot air outlet pipe, and a temperature control system.

[0005] The temperature control system includes a main control chip, a temperature sensing module, an alert module, a display module, and a control module;

[0006] A detachable assembly structure is provided between the shovel blade and the hot air gun.

[0007] Preferably, the temperature sensing module includes a signal transmission module and an infrared temperature sensor. The infrared temperature sensor is installed on the top surface of the hot air gun, and the front end of the infrared temperature sensor faces the same direction as the front end of the hot air outlet pipe. The infrared temperature sensor monitors the surface temperature of the titanium alloy casting and the local acid-resistant paint in real time by emitting infrared temperature measurement light, and sends the monitored temperature value to the main control chip through the signal transmission module. The display module includes a temperature display screen installed on the front surface of the hot air gun. The main control chip sends the received temperature value to the temperature display screen. The reminder module includes a temperature judgment module and a reminder warning light. The reminder warning light is installed on the top surface of the hot air gun. The temperature judgment module is used to judge the temperature value measured by the infrared temperature sensor in real time. The control module includes a start / stop module and a timing module. The timing module can start timing when the temperature judgment module determines that the temperature exceeds the range value. If the temperature exceeds the set value for a longer period, the hot air gun is turned off by the start / stop module.

[0008] Preferably, the disassembly and assembly structure includes an insertion port and a side movable hole at the bottom left end of the hot air gun. The end of the scraper is slidably inserted into the insertion port. A pressing block is movably inserted through the side movable hole. The top end of the pressing block extends to the inside of the hot air gun and is fixed with an inner movable plate. A limit block is fixed at the bottom left end of the inner movable plate. The end of the scraper is also provided with a limit hole corresponding to the limit block. The bottom end of the limit block extends into the limit hole. A movable structure is provided between the pressing block and the side movable hole.

[0009] The movable structure includes a side groove, a spring, and a support plate. A side groove is formed on one side surface of the pressing block. A support plate is fixed to one side inner wall of the side movable hole. The end of the support plate extends into the side groove. The spring is installed between the support plate and one side inner wall of the side groove. Strip-shaped side guide blocks are fixed to both sides of the inner wall of the insertion port. Strip-shaped side guide grooves corresponding to the strip-shaped side guide blocks are formed on both sides of the end of the shovel. The strip-shaped side guide blocks slide into the strip-shaped side guide grooves.

[0010] Preferably, the hot air gun has a handle on its rear surface, and a switch is located at the bottom of the handle. Compared with the prior art, the advantages of this invention are: by using the designed hot air gun, infrared temperature sensor, and temperature control system, the heating temperature of the titanium alloy casting during the cleaning process can be precisely controlled, improving the cleaning efficiency of the acid-resistant paint on the surface of the titanium alloy casting and increasing work efficiency. Simultaneously, under the action of the reminder module and control module, timely high-temperature warnings and overheat shutdown operations can be performed to ensure the product quality of the titanium alloy casting.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1

[0018] Please see Figure 1 and Figure 5 This is the first embodiment of the present invention, which provides a technical solution: a special tool for cleaning anti-acid paint after pickling titanium alloy castings, including a hot air gun 1, a hot air outlet pipe 2 at the front end of the hot air gun 1, which can blow out hot air to heat the titanium alloy casting 10 and the local anti-acid paint 11 during subsequent operation, a power cord 4 at the rear end of the hot air gun 1 for connecting to an external power source, a scraper 7 installed at the bottom of the front end of the hot air gun 1 relative to the hot air outlet pipe 2, and a temperature control system.

[0019] The temperature control system includes a main control chip, a temperature sensing module, an alert module, a display module, and a control module;

[0020] The temperature sensing module includes a signal transmission module and an infrared temperature sensor 6. The infrared temperature sensor 6 is model MIK-AL-10. The infrared temperature sensor 6 is installed on the top surface of the hot air gun 1, and the front end of the infrared temperature sensor 6 is aligned with the front end of the hot air outlet pipe 2. The infrared temperature sensor 6 monitors the surface temperature of the titanium alloy casting 10 and the local anti-acid paint 11 in real time by emitting infrared temperature measurement light, and sends the monitored temperature value to the main control chip through the signal transmission module.

[0021] The display module includes a temperature display screen 8 installed on the front surface of the hot air gun 1. The main control chip sends the received temperature value to the temperature display screen 8 for real-time display of the temperature of the titanium alloy casting 10 and the surface of the local anti-acid paint 11 during cleaning.

[0022] The reminder module includes a temperature determination module and a reminder warning light 12. The reminder warning light 12 is installed on the top surface of the hot air gun 1. The temperature determination module is used to determine the temperature value measured by the infrared temperature sensor 6 in real time. If the temperature value exceeds the previously set range, the reminder warning light 12 will be lit to remind the user.

[0023] The control module includes a start / stop module and a timing module. The timing module can start timing when the temperature determination module determines that the temperature exceeds the range value. If the temperature exceeds the set value for a longer period of time, the hot air gun 1 will be shut down through the start / stop module to prevent the titanium alloy casting 10 from being damaged by the excessively high temperature for a long time.

[0024] The hot air gun 1 has a handle 3 on its rear surface, and a switch 5 is located at the bottom of the handle 3.

[0025] In summary, during actual operation, the operator can hold the handle 3 and aim the hot air outlet 2 at the front of the hot air gun 1 at the local acid-resistant paint 11, then press the switch 5 to allow the hot air outlet 2 to spray hot air normally to heat the local acid-resistant paint 11. At this time, the infrared temperature sensor 6 will also emit infrared temperature measurement light to monitor the surface temperature of the titanium alloy casting 10 and the local acid-resistant paint 11 in real time, and send the monitored temperature value to the main control chip through the signal transmission module. The temperature value is then displayed on the temperature display screen 8, allowing the operator to accurately control the heating temperature. When the temperature reaches... When the temperature is suitable, the acid-resistant paint 11 can be scraped off and cleaned by the scraper 7, improving cleaning efficiency. During this process, if the temperature of the heated titanium alloy casting 10 and the local acid-resistant paint 11 is too high, the warning light 12 will be lit to remind the operator so that the operator can make timely adjustments. If the operator does not make adjustments and the temperature is too high for a longer period of time than the set value, the start-stop module will shut down the hot air gun 1 to prevent the titanium alloy casting 10 from being damaged by the high temperature for a long time, thereby ensuring the accuracy and stability of the entire cleaning process.

[0026] Example 2

[0027] Please see Figures 1 to 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the detachment structure 9 can be used to achieve quick disassembly and replacement of the blade 7, improving the overall ease of use of the tool and facilitating subsequent replacement of the blade 7.

[0028] Specifically, a disassembly and assembly structure 9 is provided between the scraper 7 and the hot air gun 1. The disassembly and assembly structure 9 includes an insertion port 91 and a side movable hole 92 at the bottom left end of the hot air gun 1. The end of the scraper 7 is slidably inserted into the insertion port 91. A pressing block 93 is movably inserted through the side movable hole 92. The top end of the pressing block 93 extends through to the inside of the hot air gun 1 and is fixed with an inner movable plate 94. A limit block 95 is welded and fixed at the bottom left end of the inner movable plate 94. The end of the scraper 7 is also provided with a limit hole 96 corresponding to the limit block 95. The bottom end of the limit block 95 extends through the limit hole 96. A movable structure 97 is provided between the pressing block 93 and the side movable hole 92.

[0029] The movable structure 97 includes a side groove 971, a spring 972, and a support plate 973. A side groove 971 is formed on one side surface of the pressing block 93. A support plate 973 is fixed to one inner wall of the side movable hole 92, with the end of the support plate 973 extending into the side groove 971. The spring 972 is installed between the support plate 973 and one inner wall of the side groove 971. When the scraper 7 needs to be removed for replacement, the operator simply presses the pressing block 93, causing it to move upwards and compressing the spring 972. This causes the inner movable plate 94, along with the limiting block 95, to move upwards, resulting in the bottom end of the limiting block 95 moving out of the limiting hole 96, releasing the horizontal limitation on the scraper 7. At this point, simply move the scraper 7 to the side, allowing its end to slide out of the insertion port 91, and the scraper 7 can be quickly removed for replacement. The same principle applies to subsequent installation of the scraper 7.

[0030] The inner walls of both sides of the insertion port 91 are fixed with strip-shaped side guide blocks, and the ends of the scraper 7 are provided with strip-shaped side guide grooves corresponding to the strip-shaped side guide blocks. The strip-shaped side guide blocks slide into the strip-shaped side guide grooves, so that the scraper 7 can only be assembled and disassembled by horizontal sliding. Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
