Description

Technical Field

[0001] This utility model belongs to the field of welding equipment, specifically relating to a tooling suitable for pulse welding. Background Technology

[0002] A thermal simulation testing machine is a dynamic simulation testing device that dynamically simulates the thermal deformation process of metals during hot working, intuitively and quickly reproducing the hot working phenomena of metallic materials. Thermal simulation testing machines are mainly used for dynamic thermo-mechanical simulation testing of materials and for sample preparation in process physics. They can control the hot working and force of materials and record mechanical property parameters such as temperature, stress, and displacement in real time.

[0003] The existing fixture was designed for standard specimens (Φ8mm*12mm). The specimen was clamped under pressure in a 20mm diameter fixture, heated to different temperatures at a specific heating rate, and then compressed to the desired compression rate. Now, a thermal simulation testing machine is needed to simulate pulse welding of two specimens with a diameter of 40mm and a height of 55mm, ensuring a strong weld. Due to the excessively large size of the specimens, the existing fixture is no longer suitable.

[0004] Therefore, a new set of tooling needs to be fabricated for the process testing of this pulse welding. Utility Model Content

[0016] The following description fully illustrates specific embodiments of the present invention to enable those skilled in the art to practice and reproduce it.

[0017] like Figure 1 The diagram shown is a structural schematic of the pulse welding fixture in this utility model.

[0018] The fixture for pulse welding includes: two opposing clamping fixtures 1, each clamping fixture 1 including: two clamping parts 7, the two clamping parts 7 being positioned opposite each other, and the inner side of each clamping part 7 having an arc surface; clamps 3 are respectively provided on both sides of the two clamping fixtures 1, the clamps 3 having threaded holes, and fastening bolts 2 are installed on the threaded holes.

[0019] The pad 5 is located between the fixture 3 and the clamping fixture 1.

[0020] The inner arc surface of the clamping assembly 7 is aligned with the diameter of the sample 4. The clamping fixture 1 is used to fix and clamp the sample 4, ensuring that the two samples 4 remain coaxial.

[0021] The clamp 3 tightens and loosens the fastening bolt 2 to clamp the fixture 1, and the other end is pressed against the inner cavity of the testing machine.

[0022] The spacer 5 is made of 30mm×6mm×50mm mold steel. It is used to fix the specimen, and both specimens are continuously subjected to force during pulse application.

[0023] Usage process: Weld thermocouple 6 to one end of sample 4, clamp the clamping fixture 1 on sample 4 and place it into the testing machine cavity, adjust the fastening bolt 2 to place fixture 3 into the testing machine cavity, adjust the fastening bolt 2 to make fixture 3 contact with clamping fixture 1, then place pad 5 between sample 4 and fixture 3, and adjust the fastening bolt 2 again to firmly fix all parts together.
