Description

Technical Field

[0001] The utility model relates to the technical field of metal material detection, in particular to a toughness detector for metal materials. Background Technique

[0002] Metal materials generally refer to pure metals or alloys in industrial applications. The properties of metal materials are generally divided into two categories: processing properties and service properties. Toughness represents the ability of a material to absorb energy during plastic deformation and fracture. The ability of a metal to resist damage under impact load is called impact toughness.

[0003] After retrieval, as disclosed in a Chinese patent document for a device for detecting the toughness of metal materials [Application No.: CN202121940682.6]. In this device for detecting the toughness of metal materials, a receiving seat is arranged above the device seat, and the receiving seat is connected to the device seat by screws. An extrusion head is arranged above the receiving seat. Second chutes are arranged on both sides of the receiving seat, and the second chutes are arranged on the device seat. A motor is arranged on one side of the device seat, and the motor is connected to the device seat by screws. A support seat is arranged above the second chute. A second slider is arranged below the support seat. One end of the second slider extends into the interior of the second chute. A bidirectional threaded rod is arranged in the interior of the second chute, and the bidirectional threaded rod is threadedly connected to the second slider.

[0004] When the device disclosed in this patent is in use, it can clamp metal materials. However, when this device is in use, since the bottom of the extrusion head is designed in a conical shape, it is inconvenient for the extrusion head to stably extrude cylindrical materials. During the extrusion process, the materials are prone to skew movement and other situations due to force deviation. Moreover, when this device is in use, the spring rod has a certain supporting force on the first slider. This supporting force is opposite to the acting force of the downward pressing device, and the elastic force of the spring rod on the support of the first slider can directly affect the dynamic force sensor. Therefore, the setting of the spring rod is prone to affect the detection data. Summary of the Utility Model

The surface of the lifting plate 8 is in contact with the inner wall of the support. Guide mechanisms 9 are arranged on both sides of the bottom of the lifting plate 8. An upper clamping frame 10 is installed at the bottom of the guide mechanism 9. Ear plates 11 are fixedly connected to the surfaces of both sides of the upper clamping frame 10. The vertical rods 5 slide through the ear plates 11. Limiting mechanisms 14 are arranged on both sides of the top of the lifting plate 8. A cross plate 15 is installed on the surface of the limiting mechanism 14. A sensor 16 is arranged on the top of the cross plate 15. A fixed frame 17 is fixedly connected to the bottom of the cross plate 15. A through groove is opened on the top of the lifting plate 8.

A protective plate 20 is fixedly connected to the top of the hollow frame 1 and is located below the adjusting mechanism 21. More preferably, the staff can electrically connect the sensor 16 to an external controller to observe data changes.

[0026] The driving mechanism 2 includes a motor 201, a lead screw 202 and a moving plate 203. The motor 201 is fixedly connected to the surface of the hollow frame 1. One end of the lead screw 202 is rotatably connected to the inner wall of the hollow frame 1. The other end of the lead screw 202 rotatably penetrates the hollow frame 1 and is fixedly connected to the output shaft of the motor 201. The number of moving plates 203 is two. The surfaces of the moving plates 203 are slidably connected to the inner wall of the hollow frame 1. The two moving plates 203 are respectively threadedly sleeved on the surface of the lead screw 202. The rectangular block 3 is fixedly connected to the top of the moving plate 203. When the staff starts the motor 201, the lead screw 202 rotates and can drive the two moving plates 203 to move towards the opposite sides, and the rectangular block 3 can drive the lower clamping frame 4 to move.

[0027] The guiding mechanism 9 includes a hollow cylinder 91, an extension rod 92, and a first compression spring 93. The top of the hollow cylinder 91 is in contact with the bottom of the lifting plate 8. The extension rod 92 slides through the bottom of the hollow cylinder 91. The first compression spring 93 is arranged inside the hollow cylinder 91. The two ends of the first compression spring 93 are respectively fixedly connected to the top of the inner wall of the hollow cylinder 91 and the top of the extension rod 92. The upper clamping frame 10 is fixedly connected to the bottom of the extension rod 92. A T-shaped plate 12 is installed at the top of the hollow cylinder 91. T-shaped grooves 13 are provided on both sides of the bottom of the lifting plate 8. The surface of the T-shaped plate 12 is in contact with the inner wall of the T-shaped groove 13. Through the setting of the guiding mechanism 9, when the lifting plate 8 descends, it can facilitate the extrusion of the upper clamping frame 10, and the guiding mechanism 9 can continuously strengthen the fixing effect of the upper clamping frame 10 on the metal material during the continuous descent of the lifting plate 8.

[0028] The limiting mechanism 14 includes a limiting rod 141, a bottom plate 142, and a top plate 143. The limiting rod 141 slides through the lifting plate 8. The bottom plate 142 and the top plate 143 are respectively fixedly connected to the two ends of the limiting rod 141. The surface of the cross plate 15 is fixedly connected to the surface of the top plate 143. The limiting mechanism 14 can guide the movement of the cross plate 15 and limit the movement range of the cross plate 15.

[0029] The positioning mechanism 18 includes a sliding rod 181, a lifting plate 182, a second compression spring 183, and a positioning block 184. The surface of the sliding rod 181 is slidably matched with the inner wall of the cavity. The lifting plate 182 is fixedly connected to the bottom of the sliding rod 181. The second compression spring 183 is arranged inside the cavity. The two ends of the second compression spring 183 are respectively fixedly connected to the inner wall of the cavity and the top of the sliding rod 181. The positioning block 184 is fixedly connected to the bottom of the lifting plate 182. The surface of the lifting plate 182 is in contact with the inner wall of the fixed frame 17. When the staff moves the lifting plate 182, the positioning block 184 can be driven to move. At this time, the second compression spring 183 is stressed and shortened, so that the fixing of the positioning block 184 on the adjusting mechanism 21 can be released. Thereafter, under the action of the elastic force of the second compression spring 183, the sliding rod 181 drives the positioning block 184 to descend through the lifting plate 182 to limit the position of the adjusting mechanism 21.

[0030] The adjusting mechanism 21 includes an adjusting block 211, a pressing plate 212, a shroud plate 213 and a convex block 214. The adjusting block 211 is rotatably sleeved on the surface of the rotating shaft 19. The pressing plate 212 is fixedly connected to the surface of one side of the adjusting block 211. The shroud plate 213 is fixedly connected to the surface of the other side of the adjusting block 211. The convex block 214 is embedded in the inner wall of the shroud plate 213. Positioning grooves are formed on the surfaces of the other two sides of the adjusting block 211. The surface of the positioning block 184 is in contact with the inner wall of the positioning groove. The cooperation of the positioning block 184 and the positioning groove can facilitate the staff to fix the state of the adjusting block 211. The adjusting block 211 can press the relatively flat metal material. The cooperation of the shroud plate 213 and the convex block 214 can press the cylindrical metal material to detect the toughness of the metal material.

[0031] Working principle: The staff first adjusts the state of the adjusting mechanism 21 according to the shape of the metal material. When the metal material is relatively flat, the staff can rotate the adjusting block 211 while pulling the lifting plate 182 so that the pressing plate 212 faces downward. When the metal material is cylindrical, the staff can rotate the adjusting block 211 and adjust the shroud plate 213 to the Figure 1 state shown. Subsequently, under the action of the elastic force of the second compression spring 183, the positioning block 184 descends and cooperates with the positioning groove to fix the position of the adjusting block 211;

[0032] The staff can first adjust the position of the lower clamping frame 4 according to the length of the metal material, that is, the staff starts the motor 201, the lead screw 202 rotates accordingly and drives the two rectangular blocks 3 to move simultaneously through the two moving plates 203, and the lower clamping frame 4 drives the vertical rod 5 to move accordingly. The position of the upper clamping frame 10 is adjusted along with the movement of the lower clamping frame 4. Thereafter, the staff starts the electric push rod 6, the connecting plate 7 drives the lifting plate 8 to descend, and the guiding mechanism 9 drives the upper clamping frame 10 to descend accordingly. The upper clamping frame 10 and the lower clamping frame 4 cooperate to clamp and fix both ends of the metal material. The connecting plate 7 continuously drives the lifting plate 8 to descend, the first compression spring 93 is compressed and shortened, and the fixed frame 17 continuously descends until the adjusting mechanism 21 can contact the metal material. The fixed frame 17 continues to descend along with the lifting plate 8, and the adjusting mechanism 21 can press the metal material. During this process, the fixed frame 17 drives the cross plate 15 to lift, and the top of the sensor 16 contacts the bottom of the disc. Thereafter, the piston rod of the electric push rod 6 continuously extends, and the sensor 16 is stressed to obtain the detection data. During this process, when the metal material is bent to a certain extent, the protection plate 20 can support the metal material to reduce the impact of the fracture of the metal material on the driving mechanism 2. Thus, the operation of detecting the toughness of the metal material can be completed.
