Description

Technical Field

[0001] This utility model belongs to the field of welding technology, specifically relating to a test plate welding clamping device. Background Technology

[0002] In the development and evaluation of welding processes, test plate welding experiments are typically conducted to assess welding quality, determine the optimal welding process, and apply it to welding production tasks. Many factors influence welding quality, such as ambient temperature, test plate assembly quality, welding parameters, and welding speed. Existing test plate welding clamping devices are often too simple, resulting in insecure test plate fixation, easy displacement during welding, and compromised welding quality. Some devices even rely solely on simple clamping methods, lacking monitoring and adjustment functions for other influencing factors during welding, such as welding temperature and deformation. This can cause the experimental process to deviate from actual production conditions, affecting the effectiveness of the final welding procedure specification. Therefore, there is an urgent need for a tool that facilitates test plate clamping and temperature adjustment, utilizing the adjustability of the device to simulate actual production conditions, thereby obtaining welding test data that more closely approximates production realities.

[0009] Multiple temperature control elements are installed in the temperature control element mounting holes of the base and connected to the temperature control system. The temperature control system monitors the temperature and controls the working status of each temperature control element, keeping the temperature of the base and the test plate to be welded at the preset temperature. This simulates the welding environment temperature, the preheating temperature of the test plate before welding, and the slow cooling temperature after welding. It also regulates the post-weld cooling rate of the weld and the heat-affected zone, ensuring the performance of the test plate weld.

[0014] Furthermore, the side wall of the back protective block of the weld is provided with a vent hole that communicates with the gas supply hole on the base. By connecting with the protective gas supply system, it can provide protective gas to the high-temperature metal on the back of the weld of the test plate during welding, ensuring the formation of the back weld and the welding quality.

[0015] Furthermore, countersunk holes are machined at the upper part of both ends of the back protective block of the weld, and deformation adjustment screws are installed in the countersunk holes.

[0027] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0028] This embodiment proposes a test plate welding clamping device, the overall structure of which is as follows: Figures 1-3 As shown, the test plate welding clamping device mainly includes a base 1, a clamping plate 2, a quick-locking pin 3, a fastening screw 4, a weld back protection block 5, a deformation adjustment screw 6, a locking screw 7, a temperature control element, and a temperature control system.

[0029] like Figure 4 and 5As shown, base 1 is a rectangular plate structure made of high-strength steel. A rectangular test plate mounting slot is machined on base 1, and a weld back protection block mounting slot is further machined on the test plate mounting slot. The bottom surface of the weld back protection block mounting slot is lower than the bottom surface of the test plate mounting slot, and a protection block removal hole is machined on the bottom surface of the weld back protection block mounting slot. Multiple through-hole clamping holes are machined on the top of both sides of the test plate mounting slot. Multiple air supply holes, multiple locking screw mounting holes, and multiple temperature control element mounting holes are machined on the side walls of base 1. To facilitate the removal of the welded test plate, a plate removal slot communicating with the test plate mounting slot is also machined on the side walls of base 1, allowing tools to be inserted to pry the test plate up and remove it from the bottom.

[0030] The weld back protection block 5 is made of materials such as copper or stainless steel. The appropriate material and processing technology are selected based on the welding test plate material and welding requirements. Copper or stainless steel is used when welding aluminum alloy test plates; copper is used when welding steel test plates. The shape of the weld back protection block mounting groove is determined according to the requirements for weld back forming, ensuring that the weld metal does not adhere to or fuse with the weld back protection block 5 during welding. The weld back protection block 5 is installed in the weld back protection block mounting groove of the base 1 through a transition fit. After installation, the top of the weld back protection block 5 is lower than the bottom surface of the test plate mounting groove. Figure 6 As shown.

[0031] Two test plates to be welded can be installed in the test plate mounting slot and positioned above the weld back protection block 5. A flux pad can be installed in the weld back protection block mounting slot as needed. The side wall of the weld back protection block 5 is provided with a vent hole that communicates with the gas supply hole on the base 1. By connecting to the shielding gas supply system, shielding gas can be provided to the high-temperature metal on the back of the test plate weld during welding, ensuring the formation and quality of the back weld.

[0032] The upper ends of the weld back protection block 5 are machined with countersunk holes, and deformation adjustment screws 6 are installed in the countersunk holes. By controlling the height of the deformation adjustment screws 6, the angle of the test plate can be adjusted to achieve reverse deformation control of the test plate (when reverse deformation control is not required, the deformation adjustment screws 6 are installed in the countersunk holes of the weld back protection block 5 and do not affect the welding of the test plate). When replacing the weld back protection block 5, it is removed by tapping with a tool through the two disassembly holes located on the base 1.

[0033] Multiple locking screws 7 are respectively installed in the locking screw mounting holes on both sides of the base 1 to adjust the gap between the two test plates to be welded. Depending on the test requirements, if the area to be welded on the test plate does not require a gap, or if different gaps need to be controlled, the gap control requirements of the test plates to be welded can be achieved by cooperating the locking screws 7 with a feeler gauge (or gap gauge).

[0034] Four clamping plates 2 are fixedly installed at the clamping mounting holes of the base 1 by quick-locking pins 3. Each clamping plate 2 has a fastening screw 4 installed at the top front end. After the test plate is installed into the test plate mounting slot, the test plate to be welded is pressed and fixed from above by adjusting the fastening screw 4.

[0035] The temperature control element includes multiple heating units 8 and multiple cooling units 9. The heating units 8 and cooling units 9 are respectively installed in the temperature control element mounting holes of the base 1. The heating units 8 and cooling units 9 are spaced apart and symmetrically distributed to ensure consistent temperature control on both sides of the test plate during welding. The heating units 8 and cooling units 9 are connected to a temperature control system, which monitors the temperature and controls the operating status of each heating unit 8 and cooling unit 9, maintaining the temperature of the base 1 and the test plate to be welded at a preset temperature. This simulates the welding environment temperature, the preheating temperature of the test plate before welding, and the slow cooling temperature after welding, regulating the post-weld cooling rate of the weld and heat-affected zone to ensure the performance of the test plate weld.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
