Description

Technical Field

[0001] The invention belongs to the technical field of alloy hardness testing, and in particular relates to a hardness testing device for alloy production. Background Art

[0002] The hardness of an alloy refers to the ability of an alloy material to resist puncture or scratching of the surface, and is usually used to evaluate the mechanical properties of the material when subjected to force. The hardness of an alloy is usually measured by hardness test methods (such as Rockwell hardness, Barcol hardness, Vickers hardness, etc.), which can reflect important characteristics of the alloy such as strength, wear resistance and processing adaptability. Hardness testing is usually measured by applying standardized pressure or load to form a hardness mark on the surface of the material. The hardness value can be a unitless value or expressed in standardized measurement units. Generally speaking, the higher the hardness of an alloy, the stronger its ability to resist deformation and wear. The hardness of an alloy has an important influence on material selection, engineering design, and material processing. Different alloy compositions and treatment methods can significantly affect their hardness, making them suitable for different industrial applications, such as manufacturing mechanical parts, tools, aerospace components, etc.

[0003] During the alloy production process, the alloy needs to be sampled and tested for hardness to ensure that the alloy meets the product standards. The existing alloy testing requires manual sampling of samples and sending them to the laboratory for testing, which is inefficient. At the same time, during the alloy hardness testing process, it is necessary to apply large and long-term pressure to the alloy surface. It is difficult to apply large and long-term pressure to the alloy that has been moving on the assembly line. If the test is to be carried out, the alloy needs to be kept still for a long time, which causes the assembly line to stop working at irregular intervals. Therefore, it is not suitable for large-scale assembly line production. At the same time, the metal undergoing hardness testing is not suitable for subsequent processing because the surface has undergone plastic deformation. It needs to be removed from the assembly line to avoid subsequent processing operations that may result in poor performance of the finished product. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a hardness testing device for alloy production.

[0005] The technical solution adopted to solve the above technical problems is: a hardness testing device for alloy production, comprising a support frame, the upper end of the support frame is fixedly connected to a conveyor belt, one end side of the conveyor belt is fixedly connected to a console, the side of the end of the conveyor belt close to the console is fixedly connected to a push-out mechanism, the end of the conveyor belt away from the console is slidably connected to a mobile test bench, a fixing mechanism is arranged on the mobile test bench, and a material discharge chute is fixedly connected to the side of the conveyor belt away from the push-out mechanism; The conveyor belt includes a pair of side plates fixedly connected to the support frame, the mobile test bench includes a first fixed plate fixedly connected between the pair of side plates, a slide bar is fixedly connected to the first fixed plate, a mobile platform is slidably connected to the slide bar, and a fixing mechanism is fixedly connected to the lower end of the mobile platform; One end of the slide bar away from the first fixed plate is fixedly connected to the second fixed plate, and both ends of the second fixed plate are fixedly connected to guide plates, and a guide slideway is provided on the inner side of the guide plate.

[0006] Through the above technical solution, the motor drives the belt to rotate, and the belt drives the mobile test bench to move with the alloy through the cooperation of the first wedge block and the second wedge block. At this time, the test punch is pushed down by the hydraulic cylinder to form a deformation mark on the surface of the alloy. After that, when the mobile test bench touches the second button, the deformation mark is photographed and measured by the camera. Finally, the push plate is driven by the first cylinder to push the alloy into the unloading chute, so that the hardness of the alloy can be tested without stopping the assembly line, which greatly improves the production efficiency.

[0007] Furthermore, a plurality of rollers are rotatably connected between the side panels, a strip hole is provided on the side panel, a pair of first grooves is provided on the roller, a motor is fixedly connected to the side surface of one end of the side panel, a gearbox is fixedly connected to the motor, a belt is provided on the outer sleeve of the roller, a plurality of pairs of first wedge blocks are fixedly connected to the inner side of the belt, and the outer sides of the side panels are fixedly connected to first slide rails.

[0008] Through the above technical solution, the first groove can be set to avoid interference between the first wedge block and the roller during the rotation of the belt, and the strip hole can be set to enable the mobile test platform to move inside the belt.

[0009] Furthermore, the console includes a control panel fixedly connected to the side panel, a plurality of first buttons are fixedly connected to the upper surface of the control panel, and a display is fixedly connected to the upper surface of the control panel.

[0010] Through the above technical solution, the whole system can be controlled through the control panel and the camera measurement data can be viewed through the display.

[0011] Furthermore, the ejection mechanism includes a first fixed frame fixedly connected to the side plate, a second fixed frame fixedly connected to the upper surface of the first fixed frame, a camera fixedly connected to the second fixed frame, a first cylinder fixedly connected to the upper surface of the first fixed frame, a push plate fixedly connected to the output end of the first cylinder, and a second button fixedly connected to the side of the second fixed frame close to the mobile test bench.

[0012] Through the above technical solution, when the sliding frame moves to one end of the first slide rail and touches the second button, after a delay of several seconds, when the alloy moves to directly below the camera under the drive of the belt, the camera takes a picture of the upper surface of the alloy to obtain the width of the mark. The hardness of the alloy can be obtained by the width and the pressure of the hydraulic cylinder. Then, the first cylinder drives the push plate to push the alloy to the unloading chute, thereby discharging the alloy.

[0013] Furthermore, a tension spring is arranged between the first fixed plate and the movable platform, a bracket is fixedly connected to the lower surface of the movable platform, the upper end of the bracket passes through and is fixedly connected to a hydraulic cylinder, a plurality of springs are fixedly connected in the movable platform, the lower end of the spring is fixedly connected to a lifting plate, the upper surface of the lifting plate is fixedly connected to a second wedge block, both ends of the lifting plate are fixedly connected to a limiting rod, the second wedge block passes through and is slidably connected to the movable platform, a guide groove is opened on the upper surface of the movable platform, both ends of the guide groove are flared, the first wedge block and the second wedge block are engaged with each other, and a test punch is fixedly connected to the output end of the hydraulic cylinder.

[0014] Through the above technical scheme, the first wedge block on the belt can be clamped with the second wedge block, so that the belt drives the mobile platform to move, and the mobile test platform moves synchronously with the belt. The test punch is driven down by the hydraulic cylinder and the pressure is maintained for several seconds to press an imprint on the alloy surface. The first wedge block and the second wedge block can be engaged with each other by the expansion setting at both ends of the guide groove.

[0015] Furthermore, the guide slide includes a first slide opened on the inner side of the guide plate, a second slide opened on one end of the guide plate close to the second fixed plate, and a third slide opened on the guide plate close to the lower end of the second slide. A fourth slide is opened on the end of the guide plate away from the second slide, and a fifth slide is opened on the guide plate close to the fourth slide. A one-way door is rotatably connected to a position on the guide plate close to the junction of the first slide and the fifth slide. The first slide, the second slide, the third slide, the fourth slide and the fifth slide are connected to each other, and the first slide, the second slide, the third slide, the fourth slide and the fifth slide are all slidably matched with the limit rod.

[0016] Through the above technical solution, when the mobile test bench is moved by the belt, the limit rod moves in the first slide. When it moves to the end, the limit rod moves downward under the action of the spring and enters the third slide through the second slide, thereby disengaging the first wedge block from the second wedge block, so that the mobile test bench is reset under the action of the tension spring, which is convenient for the next test. The use of a one-way door can prevent the limit rod from falling into the fourth slide during the movement.

[0017] Furthermore, the fixing mechanism includes a second slide rail fixedly connected to the lower end of the first fixed plate, the lower end of the first fixed plate is fixedly connected to a second cylinder, the output end of the second cylinder is fixedly connected to a movable plate, both ends of the movable plate are rotatably connected to a first connecting rod, the end of the first connecting rod away from the movable plate is rotatably connected to a sliding frame, and the sliding frame and the second slide rail slide in cooperation with each other.

[0018] Through the above technical solution, the second cylinder drives the movable plate to move, the movable plate drives the first connecting rod to rotate, and the first connecting rod drives the sliding frame to move along the second slide rail.

[0019] Furthermore, a second connecting rod is fixedly connected to the sliding frame, and both ends of the second connecting rod are rotatably connected to a third connecting rod, an end of the third connecting rod close to the second cylinder is rotatably connected to a fourth connecting rod, an end of the third connecting rod away from the fourth connecting rod is rotatably connected to a fifth connecting rod, an end of the fifth connecting rod away from the third connecting rod is rotatably connected to a mounting plate, the mounting plate and the first sliding rail slidably cooperate with each other, a guide rod is slidably connected to the mounting plate, an end of the guide rod away from the mounting plate is fixedly connected to a clamping plate, the clamping plate is rotatably connected to the fourth connecting rod, and an electrode sheet is fixedly connected to the inner side of the clamping plate.

[0020] Through the above technical scheme, the sliding frame can drive the second connecting rod to move inward, the second connecting rod can drive the third connecting rod to rotate, and the third connecting rod can drive the clamping plate to move inward along the guide rod through the limiting cooperation of the fourth connecting rod and the fifth connecting rod. At this time, if no current is generated between the electrode sheets on the clamping plates, no alloy will exist between the surface clamping plates. If alloy exists between the clamping plates, the alloy will conduct electricity to generate current between the electrode sheets. At the same time, the alloy can be centered and clamped by the clamping plates moving closer together.

[0021] The beneficial effects of the present invention are as follows: (1) The present invention arranges a conveyor belt and a mobile test bench so that the motor drives the belt to rotate, and the belt drives the mobile test bench to move with the alloy through the cooperation of the first wedge block and the second wedge block. At this time, the test punch is pushed down by the hydraulic cylinder to form a deformation mark on the surface of the alloy. After that, when the mobile test bench touches the second button, the deformation mark is photographed and measured by the camera, and finally the push plate is driven by the first cylinder to push the alloy into the unloading slide, so that the hardness of the alloy is tested without stopping the production line, which greatly improves the production efficiency. (2) The present invention uses a fixing mechanism to push the moving plate to move through the second cylinder, and the moving plate drives the sliding frame to move through the first connecting rod, and the sliding frame is driven by the second connecting rod and the third connecting rod. The connecting rod, the fourth connecting rod and the fifth connecting rod drive the clamping plates to move inward to clamp the alloy. At this time, if there is alloy between the electrode plates, the alloy can be conducted to generate current between the electrode plates. If no current is generated, it means that there is no alloy between the clamping plates, so that it can be judged whether the position of the alloy is correct. At the same time, the alloy can be centered and fixed by clamping the clamping plates, so as to facilitate the hardness test of the alloy; (3) The present invention uses a guide slide and a mobile test bench. When the mobile test bench is driven by a belt, the limit rod moves in the first slide. When it moves to the head, the limit rod moves downward under the action of the spring and enters the third slide through the second slide, so that the first wedge block is separated from the second wedge block, and the mobile test bench is reset under the action of the tension spring, so as to facilitate the next test.

The belt 25 transports the alloy to the position of the mobile test platform 5.

[0032] The sliding frame 65 is fixedly connected with a second connecting rod 66, and both ends of the second connecting rod 66 are rotatably connected with a third connecting rod 67. The end of the third connecting rod 67 close to the second cylinder 62 is rotatably connected with a fourth connecting rod 68, and the end of the third connecting rod 67 away from the fourth connecting rod 68 is rotatably connected with a fifth connecting rod 69. The end of the fifth connecting rod 69 away from the third connecting rod 67 is rotatably connected with a mounting plate 610. The mounting plate 610 and the first slide rail 29 are slidably matched with each other. The mounting plate 610 is slidably connected with a guide rod 611. The end of the guide rod 611 away from the mounting plate 610 is fixedly connected with a clamping plate 612. The clamping plate 612 and the fourth connecting rod 68 are fixedly connected. Rotational connection, an electrode sheet 613 is fixedly connected to the inner side of the splint 612, the sliding frame 65 drives the second connecting rod 66 to move inward, the second connecting rod 66 drives the third connecting rod 67 to rotate, and the third connecting rod 67 drives the splint 612 to move inward along the guide rod 611 through the limiting cooperation of the fourth connecting rod 68 and the fifth connecting rod 69.

If there is alloy between the splints 612, the alloy conducts electricity to generate current between the electrode sheets 613. At the same time, the alloy can be centered and clamped by the approach of the splint 612.

[0033] like Fig.14 and Fig.15As shown, a guide slide 7 is provided on the inner side of the guide plate 54, and the guide slide 7 includes a first slide 71 provided on the inner side of the guide plate 54, a second slide 72 is provided on one end of the guide plate 54 close to the second fixed plate 53, and a third slide 73 is provided on the guide plate 54 close to the lower end of the second slide 72. A fourth slide 74 is provided on the end of the guide plate 54 away from the second slide 72, and a fifth slide 75 is provided on the guide plate 54 close to the fourth slide 74. A one-way door 76 is rotatably connected to the position of the guide plate 54 close to the intersection of the first slide 71 and the fifth slide 75. The first slide 71, the second slide 72, the third slide 73, the fourth slide 74 and the fifth slide 75 are connected, and the first slide 71, the second slide 72, the third slide 73, the fourth slide 74 and the fifth slide 75 are all slidably matched with the limit rod 510, and the belt 25 passes through the first wedge When the block 26 drives the moving platform 56 to move, the limit rod 510 moves in the first slideway 71. When it moves to the end of the first slideway 71, the spring 57 pushes the lifting plate 58 to move downward, so that the lifting plate 58 drives the limit rod 510 to move down along the second slideway 72 to the third slideway 73. At this time, the lifting plate 58 drives the second wedge block 59 to move downward and break away from the contact with the first wedge block 26, so that the tension spring 55 drives the moving platform 56 to return along the second slideway 72. When the moving platform 56 returns to the end of the third slideway 73, the limit rod 510 moves along the fourth slideway 74, lifts the lifting plate 58, resets the second wedge block 59, and pushes open the one-way door 76 to enter the fifth slideway 75, waiting for the next time the first wedge block 26 is stuck in the second wedge block 59. At this time, due to the obstruction of the one-way door 76, the limit rod 510 re-enters the first slideway 71 instead of entering the fourth slideway 74.

[0034] The working principle of this embodiment is as follows: the motor 28 drives the roller 23 to rotate through the gearbox 27, and the roller 23 drives the belt 25 to rotate. The belt 25 transports the alloy to the position of the mobile test platform 5. At this time, the first wedge block 26 on the belt 25 clamps the second wedge block 59, so that the belt 25 drives the mobile platform 56 to move, so that the mobile test platform 5 and the belt 25 move synchronously; Then the second cylinder 62 drives the moving plate 63 to move, the moving plate 63 drives the first connecting rod 64 to rotate, the first connecting rod 64 drives the sliding frame 65 to move along the second slide rail 61, the sliding frame 65 drives the second connecting rod 66 to move inward, the second connecting rod 66 drives the third connecting rod 67 to rotate, and the third connecting rod 67 drives the clamping plate 612 to move inward along the guide rod 611 through the limiting cooperation of the fourth connecting rod 68 and the fifth connecting rod 69. At this time, if no current is generated between the electrode sheets 613 on the clamping plate 612, there is no alloy between the surface clamping plates 612. If there is alloy between the clamping plates 612, the alloy conducts electricity to generate current between the electrode sheets 613, and at the same time, the clamping plates 612 move closer together to allow the alloy to be centered and clamped. Then, the hydraulic cylinder 512 drives the test punch 513 to press down and maintain the pressure for several seconds, so as to press a mark on the surface of the alloy. Then, the second cylinder 62 drives the moving plate 63 to move in the opposite direction, so that the clamping plate 612 releases the alloy, and the sliding frame 65 touches the second button 46 when it moves to one end of the first slide rail 29. After a delay of several seconds, when the alloy moves to the bottom of the camera 43 under the drive of the belt 25, the camera 43 takes a picture of the upper surface of the alloy, so as to obtain the width of the mark. The hardness of the alloy can be obtained by the width and the applied pressure. Then, the first cylinder 44 drives the push plate 45 to push the alloy to the unloading slide 8, so as to discharge the alloy. When the belt 25 drives the movable platform 56 to move through the first wedge block 26, the limit rod 510 moves in the first slideway 71. When it moves to the end of the first slideway 71, the spring 57 pushes the lifting plate 58 to move downward, so that the lifting plate 58 drives the limit rod 510 to move down along the second slideway 72 to the third slideway 73. At this time, the lifting plate 58 drives the second wedge block 59 to move downward and break away from the contact with the first wedge block 26, so that the tension spring 55 drives the movable platform 56 to return along the second slideway 72. When the movable platform 56 returns to the end of the third slideway 73, the limit rod 510 moves along the fourth slideway 74, lifts the lifting plate 58, resets the second wedge block 59, and pushes open the one-way door 76 to enter the fifth slideway 75, waiting for the next time the first wedge block 26 is stuck in the second wedge block 59. At this time, due to the obstruction of the one-way door 76, the limit rod 510 re-enters the first slideway 71 instead of entering the fourth slideway 74.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
