Description

Technical Field

[0001] This utility model relates to the field of upsetting testing machines, and specifically to a support device for upsetting testing machines. Background Technology

[0002] In the field of metal processing and testing, upsetting is a commonly used testing method to evaluate the plastic deformation capacity and weldability of materials. During the upsetting test, the specimen (material) needs to be precisely clamped and positioned in a designated location on the testing machine so that the hydraulic rod can apply pressure to perform the upsetting operation. However, traditional upsetting testing machine support devices have some problems that affect the accuracy and efficiency of the test.

[0003] First, the traditional support device's workbench design is often relatively simple and lacks the necessary positioning and correction functions, which makes the sample prone to displacement or tilting during the test, thus affecting the accuracy of the test results.

[0004] Therefore, in order to solve the above-mentioned problems, a support device for upsetting testing machine was designed. Utility Model Content

[0005] This invention addresses the problems mentioned above by designing a support device for an upsetting testing machine. This device can clamp and position small-sized test materials, making the experimental data more accurate.

[0006] To achieve the above objectives, this utility model provides a support device for an upsetting testing machine, comprising: a worktable, a clamping and straightening device, a driving device, and a base. The worktable is cylindrical, and the base is fixedly connected to the worktable surface of the testing machine and located below the hydraulic rod of the testing machine. The worktable is fixedly connected to the base, and the material is placed on the worktable. The driving device is annular, and is fixedly connected to the base and arranged around the periphery of the worktable. There are several clamping and straightening devices arranged in a circumferential array on the worktable. One end of each clamping and straightening device is connected to the driving device, and the other end is in contact with the side of the material.

[0007] In the above manner, the material is placed on the worktable, and the clamping and straightening device is driven by the drive device to move closer to the inside of the worktable to straighten and position the material. Then it is withdrawn and reset to avoid the working range of the hydraulic rod of the testing machine.

[0008] Furthermore, the workbench includes: a positioning plate, an extension portion, and an installation notch. The positioning plate is fixedly connected to the top surface of the workbench. The extension portion has four parts arranged in a circumferential array on the edge of the positioning plate, and the installation notch is provided on the extension portion.

[0009] Furthermore, the clamping and straightening device includes: a threaded rod, a limiting rod, a slider, and a driven gear. The threaded rod is rotatably connected within the mounting notch, the limiting rod is fixedly connected within the mounting notch, the slider is threadedly connected to the threaded rod and slidably connected to the limiting rod, the slider is provided with a clamp that abuts against the material, the driven gear is located at the end of the extension portion and is fixedly connected to the threaded rod, and the driven gear is connected to the driving device.

[0010] Furthermore, the clamp on the slider includes a support plate, a connecting rod, and an arc-shaped plate. The support plate is fixedly connected to the slider, one end of the connecting rod is fixedly connected to the support plate, and the other end is fixedly connected to the arc-shaped plate. The arc-shaped plate is in contact with the side of the material.

[0011] In this way, the slider is slidably connected to the worktable through the lead screw mechanism, and the fixture moves under the drive of the slider to position and correct the material.

[0012] Furthermore, the driving device includes: an outer ring gear, a support platform, a support column, and a motor. The support column is disposed on the base, the support platform is fixedly connected to the support column, the outer ring gear is rotatably connected to the support platform, the outer ring gear is connected to the clamping and straightening device, and the motor is mounted on the base with its output end connected to the inner surface of the outer ring gear.

[0013] In this way, the outer ring gear rotates under the drive of the motor, which in turn drives the driven gear to rotate. The driven gear then drives the threaded rod to rotate, which in turn drives the slider to move.

[0014] Furthermore, the height of the arc-shaped plate is less than the height of the material.

[0015] In summary, this utility model has the following advantages and beneficial technical effects:

[0016] 1. The present invention provides a support device for an upsetting test machine that can correct the position of the material to be upsetting, so that the material is located in the center of the worktable, making the force more uniform and improving the accuracy of the test.

[0017] 2. The support device for an upsetting testing machine of this utility model synchronously drives four clamping and straightening devices through a drive device, resulting in higher precision;

[0018] 3. The support device for an upsetting test machine of this utility model can clamp and position small test materials, making the experimental data more accurate. Attached Figure Description
