Description

Technical Field

[0001] This utility model relates to the technical field of metal part testing experimental sample trays, specifically a sample tray with multiple specification adaptation functions. Background Technology

[0002] There are various testing experiments for metal parts, including the flattening test. Common workpiece materials for the flattening test are pipes and other tubular materials. The flattening test is a method used to evaluate the mechanical and forming properties of metal pipes, profiles, and other materials with specific shapes. Workpiece materials include seamless and welded steel pipes, as well as metal profiles with special cross-sections, such as I-beams, channel steel, and angle steel. These special cross-section profiles may be subjected to various complex loads during processing and use. The flattening test can verify the stability of their cross-sectional shape under compression, as well as the material's local deformation capacity, providing a basis for the design and use of the profiles.

[0003] In existing flattening tests, a clamp is installed on the testing machine to position and clamp the workpiece, and then a hydraulic system is used to achieve the downward pressing action from top to bottom. For example, CN201621190598.6 describes an online flattening test device for sharp-angled steel pipes. The existing sample tray has the following problems:

[0004] 1) Firstly, the placement of the workpiece is limited by the support blocks on both sides. However, the two sides use springs to quickly abut against the workpiece. After a long period of use, it is impossible to guarantee that the two sets of springs can maintain the clamping effect. Moreover, even if it can clamp, it will not be symmetrical from left to right depending on the placement position.

[0005] 2) Secondly, in the existing experiments, it was found that there are many different sizes of the same type of workpiece. When the flattened deformation is broken, a large or rapid impact will occur, causing the support block to be damaged quickly.

[0006] 3) Currently, after placing the workpiece, it is mostly observed by the naked eye whether it is horizontal. Although a vertical ruler is set in the existing technology, it is still necessary to observe whether the workpiece is placed horizontally. It cannot effectively make the workpiece symmetrical along the center line on the two sets of support plates.

[0007] To address these issues, we provide a sample tray with multiple size compatibility features. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sample tray with multiple specification adaptability functions to solve the problem that it is difficult to ensure that the workpiece is on the center line of the sample base plate and reduce the adverse effect of effective flattening caused by tilting.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sample tray with multiple specification adaptability functions, comprising:

[0010] The sample base plate has a transverse track and an installation groove at the bottom.

[0011] The support blocks are arranged in two sets symmetrically, and the two sides facing each other are provided with inclined surfaces, which are suitable for abutting against the two sides of the workpiece.

[0012] The bottom cavity contains a magnet; there are two sets of mounting grooves, with the bottom cavity located between the two sets of mounting grooves.

[0013] A lateral tie rod is provided, comprising a lateral rod and a boundary protrusion on the side of the sample base plate. One end of the lateral rod is adapted to penetrate the boundary protrusion, and the other end of the lateral rod is connected to the side of the support block opposite to the workpiece.

[0014] Multiple sets of laterally distributed positioning holes are provided on the sample base plate. Positioning elements are detachably installed in the positioning holes. The positioning elements are located on the side of the support block facing away from the workpiece and are suitable for limiting the movement limit position of the support block.

[0015] In a further technical solution, two sets of horizontal rails are respectively provided on the horizontal rails, both located at the bottom of the support block. The horizontal rails are respectively provided with a first protrusion and a first groove, both arranged horizontally. A slide rail plate is installed at the bottom of the support block. The slide rail plate is respectively provided with a second protrusion and a second groove. The first protrusion is adapted to the second groove, and the second protrusion is adapted to the first groove.

[0016] In a further technical solution, an indicator plate is slidably installed on the outer end of the transverse track. The indicator plate is C-shaped and open upwards, with vertical dimension markings at both ends and fitted with sliding claws. A transverse strip is provided between the two sets of sliding claws.

[0017] In a further technical solution, the positioning component includes a bottom screw and an end cap. The end cap is conical and installed on the sample base plate, and the bottom screw is installed at the bottom. The bottom screw is adapted to be threaded to the positioning hole and threaded upward to the bottom of the end cap.

[0018] The top of the end cap is higher than the bottom of the support block.

[0019] In a further technical solution, the lateral tie member also includes a return spring, one end of which is fixedly connected to the boundary protrusion and the other end is fixedly connected to the support block.

[0020] In a further technical solution, the support block has an installation opening on the side facing away from the workpiece, and the inner diameter of the installation opening is adapted to the diameter of the reset spring.

[0021] In a further technical solution, a vertical rod is fixedly connected to the middle of the indicator plate, a fixed plate is integrally provided at the bottom of the vertical rod, and a movable plate is installed on the rod body; a vertical spring is installed between the movable plate and the fixed plate, and a pressure column is detachably installed on the side of the movable plate opposite to the workpiece.

[0022] The vertical rod is a threaded rod, and an adjusting nut is installed on the vertical rod on the moving plate. The adjusting nut is threadedly connected to the vertical rod.

[0023] In a further technical solution, the sample base plate on the magnet is provided with a high-strength zone, and a high-strength wear-resistant plate is provided in the high-strength zone. Transition holes are opened on both sides of the high-strength wear-resistant plate, and two sets of magnets are provided at the bottom of the high-strength wear-resistant plate.

[0024] Compared with existing technologies, it has the following advantages:

[0025] In this embodiment, a transverse track and a slide rail plate are connected by a protruding strip and a recessed groove. The connection between the protruding strip and the recessed groove restricts the slide rail plate to slide on the transverse track, causing the top to move the support block. The connection between the transverse track and the slide rail plate ensures the predictability of the support block's movement direction. A magnet is used to attract the workpiece material, reducing the likelihood of workpiece wobbling. End caps are provided to prevent sudden deformation of the metal workpiece from causing lateral impacts and destructive results. The C-shaped indicator plate facilitates the vertical movement of the transverse strip and allows for quick observation of whether the workpiece is installed horizontally, offering convenience and practicality. A pressure column that can move along a vertical rod is installed on the indicator plate to ensure the workpiece's installation position. Attached Figure Description

[0043] The lateral tie rod includes a lateral rod 6. A boundary protrusion 7 is provided on the side of the sample base plate 1. One end of the lateral rod 6 is adapted to penetrate the boundary protrusion 7; the other end of the lateral rod 6 is connected to the side of the support block 4 facing away from the workpiece 100.

[0044] Multiple sets of laterally distributed positioning holes 8 are provided on the sample base plate 1. Positioning components are detachably installed in the positioning holes 8.

The transverse track 2 is respectively provided with a protruding strip 9 and a recessed groove 10, both arranged transversely. A slide rail plate 11 is installed at the bottom of the support block 4. The slide rail plate 11 is respectively provided with a protruding strip 12 and a recessed groove 13. The protruding strip 9 and the recessed groove 13 are adapted to each other, and the protruding strip 12 and the recessed groove 10 are adapted to each other.

[0046] like Figure 1 As shown, an indicator plate 14 is slidably installed on the outer end of the transverse track 2. The indicator plate 14 is C-shaped and open upwards, with vertical dimension markings at both ends and fitted with sliding claws 15.
