Description

Technical Field

[0001] The utility model relates to the field of metal material processing, in particular to a device for quickly detecting the hardness of rod-shaped metal materials. Background Art

[0002] Metal raw materials can be made into finished products after processing. The materials need to be tested for hardness. The reason for the hardness test is that before the metal materials are processed, they may be mixed with impurities, resulting in uneven material strength. Some materials may not meet the quality requirements after processing. Therefore, the materials need to be tested for hardness. There are many types of materials and shapes. The most common ones are rods, plates, and blocks. For rod-shaped materials, due to their slender shape, each interval of length may have different hardness. When performing hardness testing, single-position testing cannot be performed. Traditional hardness testing equipment requires frequent clamping and loosening of the material, and lacks the means to quickly collect data. Therefore, multi-segment hardness testing of rod-shaped metal materials is very time-consuming and troublesome. Utility Model Content

[0003] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a testing device that can conveniently clamp and release materials to facilitate multi-position hardness testing, and can also intuitively view the data.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 5 As shown, the embodiment of the utility model preferably provides a rapid hardness detection device for rod-shaped metal materials, including a base 1, a cylinder 2 arranged on the base 1 for applying pressure to the material, a mounting channel 3 for accommodating and positioning the material is provided on the base 1, an adjustment structure 4 for adjusting the width of the mounting channel 3, and a quick adjustment structure 5 for quickly expanding and contracting the width of the mounting channel 3 are also provided, and a detection device 6 for detecting the feed amount of the cylinder 2 and a digital display center 7 for displaying the detection data are also provided on the base 1.

[0023] The cylinder is used to apply pressure to the material to perform hardness testing based on the molecular fracture of the material after being pressed. The installation channel is a straight channel as a whole, used to place rod-shaped metal materials. The width of the installation channel can be adjusted through the adjustment structure to accommodate more materials of different widths. The quick-adjustment structure can quickly expand or contract the width of the installation channel without using the adjustment structure, so that the material in the installation channel can be easily aligned with the cylinder at different locations, so as to achieve hardness testing at multiple locations on a single material, allowing for more accurate control of the quality of metal materials. The detection device can measure the feed depth of the cylinder on the material and display the data on the digital display center, allowing users to intuitively record and analyze the data of each hardness test.

[0024] The movable end of the cylinder 2 in the present invention is provided with a pressure head 21. The pressure head is used to press the material, and can be made of hard metal and chamfered on the periphery of the wall facing the material to reduce the accelerated breakage of material molecules caused by sharp edges, resulting in inaccurate measurement.

[0025] The installation channel 3 described in the present invention includes vertical plates 31 arranged on the left and right sides of the surface of the base 1. A gap is left between the two vertical plates 31 for the movable end of the cylinder 2 to pass through. Fasteners 32 are installed on the side close to the top of the two vertical plates 31, and sheet metal connectors 33 are provided on both sides of the rear end face of the base 1. The vertical plates are used to facilitate positioning of the material to the selected position. The gap allows the cylinder to pass through and apply pressure. The fasteners are used to connect and fix the two vertical plates so that both ends of the material can be completely limited by the vertical plates. The fasteners can be removed according to actual conditions to match the shape of the material. Under normal circumstances, sheet metal connectors are used to connect tooling baffles. Since the material is restricted between the vertical plates and the tooling baffles to achieve positioning, when materials with irregular shapes appear, they can be adapted by using tooling baffles of different shapes and adjusting the vertical plates.

[0026] The sheet metal connector 33 is provided with a tooling baffle 8. The material is restricted between the vertical plate and the tooling baffle to achieve positioning.

[0027] The adjustment structure 4 described in the present invention includes adjustment seats 41 fixed to the left and right sides of the base 1. A screw hole is defined at the top of the adjustment seat 41, into which a screw rod 42 is threadedly inserted. A hexagonal screw hole 43 is defined at the front end of the screw rod 42, and the rear end of the screw rod 42 is hinged to the side wall of the vertical plate 31. During adjustment, a tool can be inserted into the hexagonal screw hole and rotated, allowing the screw rod to rotate in the screw hole to move the screw rod forward and backward, thereby causing the vertical plate to move forward and backward. The connection between the vertical plate and the screw rod is hinged, which can be achieved by using a multi-directional hinge.

[0028] The quick-adjustment structure 5 described in the present invention includes a sliding groove 51 provided on the left and right sides of the surface of the base 1. A plurality of grooves 52 are provided on the bottom wall of the sliding groove 51, and the edges of the grooves 52 are inclined surfaces 53. A sliding member 54 is provided in the sliding groove 51, which can slide linearly along its trajectory. A plurality of protrusions 55 are provided on the bottom wall of the sliding member 54, which can be accommodated in the grooves 52 or moved into the sliding groove 51 via the inclined surfaces 53. A plurality of teeth 56 are provided on the outer surface of the screw 42, and a rack 57 is provided on the surface of the sliding member 54 to engage with the teeth 56. A hand handle 58 is also provided at the outer end of the sliding member 54. The sliding groove is a straight groove. In this technical solution, two grooves are provided in the sliding groove, and the grooves are provided with inclined surfaces on the left and right outer edges of the base. The grooves are used to accommodate the protrusions, and the inclined surfaces allow the protrusions to slide from the grooves to the position of the sliding groove. When the user pulls the handle, the raised element transitions from a groove into a sliding slot, and the slider rises from flush with the base surface to above it. As the handle continues to pull, the rack engages the teeth, rotating the screw and pulling the vertical plate, widening the installation channel. Similarly, reversing the slider narrows the installation channel and resets the vertical plate. This quick-adjust mechanism allows the installation channel to be quickly expanded or retracted, making it easy to move or exchange materials.

[0029] The detection device 6 described in this utility model comprises a detection platform 61 mounted on a base 1 and positioned to one side of the cylinder 2. A rotatable swing arm 62 is hinged to the detection platform 61, with a torsion spring 63 installed at the hinged position. A counting roller 64 is hinged to the swing arm 62, which can rotate at a fixed point. A rolling end surface 65 is provided on the side of the movable end of the cylinder 2, against which the counting roller 64 is pressed by the torsion spring 63. A roller counter 66 is connected to the swing arm 62 and positioned to one side of the counting roller 64. The swing arm is moved toward the movable end of the cylinder by the torsion spring, allowing the counting roller on it to press against the rolling end surface. The movable end of the cylinder starts in close contact with the material, and the depth at which it can be fed is used to calculate the hardness. As the movable end of the cylinder gradually extends as pressure is applied, the number of revolutions of the counting roller is recorded and counted by the roller counter. The technologies for both the counting roller and the roller counter are both currently available, and this device is widely used to measure stroke feed.

[0030] The digital display center 7 in this utility model includes a display screen 71 and operation buttons 72 mounted on the swing arm 62. The display screen 71 is connected to the roller counter 66. The data calculated by the roller counter is displayed on the display screen, and the operation buttons can be used to perform simple operations such as clearing numbers and multiplying numbers. The user can intuitively observe the display screen during hardness testing, quickly obtaining test results for easy recording.

[0031] In more embodiments of the present invention, the sheet metal connector 33 can be connected to the sheet metal connector 33 of another hardness rapid testing device that is the same as the present device. In addition to being connected to the tooling baffle, the sheet metal connector can also be connected to the sheet metal connector of another hardness rapid testing device that is the same as the present device, thereby achieving simultaneous pressure application on both sides of a wide material.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
