Description

Technical Field

[0001] The present utility model relates to the technical field of hardness detection, and specifically relates to a hardness detection device for metal products. Background Technique

[0002] Metal is a substance with luster (i.e., strong reflection of visible light), malleability, easy electrical conductivity, heat conductivity, etc. The above characteristics of metals are all related to the free electrons contained in the metal crystal lattice. In nature, the vast majority of metals exist in the form of compounds, and a few metals such as gold, platinum, silver, and bismuth exist in the free state. Most metal minerals are oxides and sulfides. Other forms of existence include chlorides, sulfates, carbonates, and silicates. The connection between metals is a metallic bond, so the position can be randomly changed and the connection can be re-established, which is also the reason for the good malleability of metals. Metal elements usually only show positive valence in compounds. Those with relatively large relative atomic mass are called heavy metals.

[0003] Metal hardness detection is the quickest, most economical, and simplest test method for evaluating the mechanical properties of metals. The main purpose of hardness detection is to determine the applicability of materials, or the effect of special hardening or softening treatments carried out on materials for use purposes.

[0004] However, the existing technology has the following problems:

[0005] 1. The existing hardness detection devices are not easy to detect the hardness of different parts of the same metal. If different parts need to be detected, the position of the metal needs to be manually moved, and the practicability is relatively low;

[0006] 2. For the existing hardness detection devices, due to the different structures of the metals to be detected, they are not fixed during detection. If the metal to be detected moves during the detection by the detection cone head, it will affect the detection result and make the detection result inaccurate. Content of the Utility Model

[0007] The purpose of the present utility model is to provide a hardness detection device for metal products to solve the problems of difficult detection of different parts and non - fixation of the metal to be detected as mentioned above.

[0008] To achieve the above purpose, the present utility model provides the following technical solution: A hardness detection device for metal products, including a support bottom plate, support legs are installed below the support bottom plate, vertical plates are installed at both ends above the support bottom plate, a T - shaped slide rail is installed between the two vertical plates through bolts, an inverted U - shaped mounting column is installed above the T - shaped slide rail, a detection cone head is installed below the inverted U - shaped mounting column, a workbench is installed at the middle position above the support bottom plate, a large hydraulic cylinder is installed at the middle position inside the workbench, and a placement plate is installed above the large hydraulic cylinder.

[0009] As a further solution of the utility model: One - way sliders are respectively slidably connected to the two T - shaped sliding rails.

The inverted U - shaped mounting column is used to install the detection cone head. The one - way electric push rods are used to provide pushing and pulling forces for the back - and - forth movement of the inverted U - shaped mounting column.

[0010] As a further solution of the utility model: A two - way slider is slidably connected to the bottom column of the inverted U - shaped mounting column. A push plate is installed at the top right end of the two - way slider. Above the right edge of the bottom column of the inverted U - shaped mounting column, a fixing plate is installed. Inside the fixing plate, a two - way electric push rod is installed. The output end of the two - way electric push rod is connected to the push plate. The two - way slider is used to drive the detection cone head to move left and right. The fixing plate is used to fix the two - way electric push rod. The two - way electric push rod cooperates with the push plate to provide pushing and pulling forces for the left - and - right movement of the two - way slider.

[0011] As a further solution of the utility model: Two small hydraulic cylinders are symmetrically installed below the two - way slider. The output ends of the small hydraulic cylinders are connected to a cross - plate. A detection cone head is installed at the middle position below the cross - plate.

[0013] As a further solution of the utility model: A placement groove is installed inside the placement plate. Installation grooves are respectively opened at both ends of most of the placement grooves. The placement grooves are used to place the metal to be detected. The installation grooves are used to install clamping hydraulic cylinders.

[0014] As a further solution of the utility model: Clamping hydraulic cylinders are installed in the two installation grooves. Clamping plates are installed at the front ends of the clamping hydraulic cylinders. The clamping hydraulic cylinders cooperate with the clamping plates to clamp the metal to be detected.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:
