Description

Technical Field

[0001] This utility model relates to the technical field of mold steel strength testing devices, and in particular to a strength testing device for mold steel processing. Background Technology

[0002] Die steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting molds. Its strength and hardness directly affect the service life and processing quality of the molds. Therefore, accurate strength testing of die steel is an indispensable part of the mold manufacturing process.

[0003] In the prior art, according to Chinese patent application number 202410797245.5, a strength testing device and method for mold steel is disclosed. This device includes a frame, a clamping assembly, a moving assembly, a pressure head assembly, a reference assembly, and a testing assembly. The clamping assembly is used to hold the workpiece to be tested. The moving assembly is mounted on the frame and is used to drive the clamping assembly to move in a horizontal plane. The pressure head assembly is mounted on the frame and located above the clamping assembly. The pressure head assembly includes a first support frame and a hardened steel ball. This invention, with its pressure head assembly, reference assembly, and testing assembly, compared to the prior art, ensures no overlap between adjacent testing points when the density of testing points on the workpiece is high. Therefore, the accuracy of the testing results is high, and after Brinell hardness conversion, it can more accurately reflect the actual strength of the workpiece.

[0004] In the prior art, according to Chinese patent application number 202410797245.5, a strength testing device and method for mold steel are disclosed. This method involves supporting and adjusting the testing device from one side, and then using the device to test the hardness of the mold steel. However, because the support is only on one side, applying pressure to the testing device can easily lead to uneven stress on one side, thus affecting the accuracy of the test results. Therefore, we propose a strength testing device for mold steel processing to solve the above problems. Utility Model Content

Motor 71 is installed on one side of lifting ring 1, and the shaft end of motor 71 is connected to one end of screw B 73. Motor 71 is connected to the power supply and controller through wires. Motor 71 drives screw B 73 to rotate, which drives screw A 72 and screw C 74 to rotate synchronously through bevel gear transmission. Screws A / B 73 drive the corresponding adjusting blocks to move axially. Screw C 74 constrains the rotational freedom of lifting ring 1 through support rod 77, realizing precise position adjustment of A / B adjusting rings 5.

The upper end of linkage column 68 is connected to the shaft end of hydraulic actuator 61. 61 connects to the power supply and controller via wires. The hydraulic actuator 61 moves up and down along with the linkage column 68. The linkage column 68 drives the moving column 66 to move, which in turn moves the pressure ball 3. The pressure ball 3 then performs a bottom inspection on the mold steel. An industrial camera is then installed on the device to measure the indentation on the mold steel and determine the hardness data. By using two pressure balls 3 to inspect the mold steel simultaneously, different positions on the cross-section of the mold steel can be inspected, which can better determine the overall processing status of the cross-section, improve the inspection effect, and improve the data collection efficiency by inspecting two positions at the same time.

[0053] Operating principle:

[0054] The mold steel is installed on the moving plate 2 by the positioning unit 9. The moving mechanism moves the moving plate 2 with the mold steel to the detection position. Then the adjusting unit 7 adjusts the position of the two pressure balls 3. The lifting mechanism moves the lifting ring 1 up and down to make the pressure balls 3 contact the mold steel. The pressing unit 6 is in a suitable position. Finally, the pressing unit 6 makes the pressure balls 3 press down on the mold steel for detection.
