Description

Technical Field

[0001] This utility model relates to the field of performance testing technology for die-cast parts, and in particular to a device for testing the mechanical properties of large die-cast parts in multiple regions. Background Technology

[0002] Die castings are parts produced by pressure casting. They are made using a pressure casting machine equipped with a casting mold. Molten metal such as copper, zinc, aluminum, or aluminum alloy is poured into the machine's feed inlet, and then pressed and cast to produce copper, zinc, aluminum, or aluminum alloy parts of the shape and size specified by the mold. These parts are commonly called die castings. Die castings have different names in different places, such as die-cast parts, pressure castings, die castings, die-cast aluminum, die-cast zinc, die-cast copper, copper die castings, zinc die castings, aluminum die castings, aluminum alloy die castings, and aluminum alloy die casting parts.

[0003] In the present technology, die-cast parts need to undergo pressure testing after production to check whether the stress meets the standard. However, traditional pressure testing requires manual operation, which results in low testing efficiency and slow speed, and cannot improve production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a multi-area mechanical property testing device for large die-cast parts, which solves the problem that traditional pressure testing requires manual operation and therefore has low testing efficiency.

[0005] To achieve the above objectives, a multi-area mechanical property testing device for large die-cast parts is provided, comprising: a testing frame, with support columns fixedly connected to both ends of the rear side of the testing frame, a top plate fixedly connected to the top of the support columns, hydraulic cylinders fixedly connected to both ends of the bottom of the top plate, a lower pressure plate fixedly connected to the extended end of the hydraulic cylinders, a bidirectional screw rotatably connected to the center of the testing frame, threaded blocks threadedly connected to both sides of the center of the bidirectional screw, a support block fixedly connected to the top of the threaded block, and a lifting plate supported above the support block.

[0006] As a preferred embodiment of this utility model, a second cylinder is fixedly connected inside the detection frame, and the extended end of the second cylinder is fixedly connected to the lifting plate.

[0007] As a preferred embodiment of this utility model, a first cylinder is fixedly connected to both sides of the bottom end of the lifting plate, and a drive roller is rotatably connected to the extended end of the first cylinder. A hub motor is installed inside the drive roller.

[0008] As a preferred embodiment of this utility model, pressure sensors are fixedly connected to both sides of the inner side of the lower pressure plate.

[0009] As a preferred embodiment of this utility model, several conveying rollers are rotatably connected to both ends of the testing frame, and pulleys are fixedly connected to both ends of the conveying rollers.

[0010] As a preferred embodiment of this utility model, a belt body is sleeved on the outer side of the pulley, and a first motor is fixedly connected to the outer end of the detection frame, with the drive end of the first motor fixedly connected to the pulley.

[0011] As a preferred embodiment of this utility model, both ends of the top of the lifting plate are fixedly connected to support seats.

[0012] As a preferred embodiment of this utility model, a second motor is fixedly connected to one side of the bottom center of the testing frame, and the drive end of the second motor is fixedly connected to a bidirectional screw.

[0013] The above-mentioned solution has the following beneficial effects: This utility model comprises a first motor, a pulley, a belt body, and conveyor rollers. The first motor drives the pulley to rotate, and the belt body, when fitted together, enables multiple conveyor rollers to move in the same direction, thus completing the conveying operation of large die-cast parts. When the large die-cast part is conveyed to the middle of the inspection frame, the drive rollers rotate, and the drive rollers stop rotating after the large die-cast part is in the middle position. Then, the first cylinder electrically retracts the large die-cast part and places it above the support seat. This structure achieves automated stopping of the conveying, facilitating pressure testing operations.

[0014] This utility model is equipped with a second motor, a bidirectional screw, a support block, and a lifting plate. The second motor drives the bidirectional screw to rotate, and after rotation, it engages with the threaded block to achieve threaded movement of the support block. After the support block is positioned below the support seat, the second cylinder descends, causing the lifting plate and support block to come into contact and support each other. At this time, the hydraulic cylinder extends and lowers the pressure plate. Through pressure sensing by the pressure sensor, pressure detection operation of large die-cast parts can be performed.

[0019] Reference Figure 1-4 The present invention relates to a multi-area mechanical property testing device for large die-cast parts, comprising: a testing frame 1, with support columns 18 fixedly connected to both ends of the rear side of the testing frame 1, a top plate 4 fixedly connected to the top of the support columns 18, hydraulic cylinders 5 fixedly connected to both ends of the bottom of the top plate 4, a lower pressure plate 7 fixedly connected to the extended end of the hydraulic cylinder 5, a bidirectional screw 9 rotatably connected to the center of the interior of the testing frame 1, threaded blocks 10 threadedly connected to both sides of the center of the bidirectional screw 9, a support block 11 fixedly connected to the top of the threaded block 10, a lifting plate 19 supported above the support block 11, a second cylinder 15 descending to bring the lifting plate 19 and the support block 11 into contact and support, at which time the hydraulic cylinder 5 extends to lower the lower pressure plate 7, and the pressure is sensed by the pressure sensor 6.

[0020] A second cylinder 15 is fixedly connected to the center of the inspection frame 1. The second cylinder 15 extends electrically to lift the lifting plate 19 and the large die-cast part. The extended end of the second cylinder 15 is fixedly connected to the lifting plate 19. The bottom two sides of the lifting plate 19 are fixedly connected to the first cylinder 13. The second motor 8 rotates in the opposite direction to disengage the support block 11 from the lifting plate 19. Then the first cylinder 13 extends to lift and drive the drive roller 14 to transport the large die-cast part, completing the unloading operation. The extended end of the first cylinder 13 is rotatably connected to the drive roller 14. When the part is transported to the middle position of the inspection frame 1, the drive roller 14 stops rotating. Then the first cylinder 13 retracts electrically to place the large die-cast part above the support seat 12. The drive roller 14 is equipped with a hub motor. Pressure sensors 6 are fixedly connected to both sides of the lower pressure plate 7. Several pressure sensors 6 are rotatably connected to the inside of both ends of the inspection frame 1. The conveyor roller 2 is used to transport large die-cast parts. Both ends of the conveyor roller 2 are fixedly connected to pulleys 16. A belt body 17 is sleeved on the outside of the pulleys 16. The outer end of the inspection frame 1 is fixedly connected to the first motor 3. Driven by the first motor 3, the pulleys 16 are rotated. Through the sleeve of the belt body 17, multiple conveyor rollers 2 can move in the same direction. The drive end of the first motor 3 is fixedly connected to the pulleys 16. Both ends of the top of the lifting plate 19 are fixedly connected to the support seats 12. The bottom middle of the inspection frame 1 is fixedly connected to the second motor 8. Driven by the second motor 8, the bidirectional screw 9 is rotated. After rotation, it engages with the threaded block 10, which moves the support block 11. After the support block 11 is below the support seat 12, the second cylinder 15 descends. The drive end of the second motor 8 is fixedly connected to the bidirectional screw 9.

[0021] Working Principle: During operation, large die-cast parts are conveyed above the conveyor rollers 2. This is driven by the first motor 3, which rotates the pulley 16. Through the engagement of the belt body 17, multiple conveyor rollers 2 move in the same direction, thus conveying the large die-cast parts. Once the parts reach the middle of the inspection frame 1, the drive roller 14 stops rotating. Then, the first cylinder 13 electrically retracts, placing the large die-cast part above the support base 12. The second cylinder 15 electrically extends, lifting the lifting plate 19 and the large die-cast part. After lifting, the second motor 8 drives the lifting plate 19 to... Rotating the screw 9 engages with the threaded block 10, allowing the support block 11 to move threadedly. Once the support block 11 is positioned below the support seat 12, the second cylinder 15 descends, bringing the lifting plate 19 and the support block 11 into contact and support. At this time, the hydraulic cylinder 5 extends, lowering the lower pressure plate 7. Pressure is detected by the pressure sensor 6, enabling pressure testing of the large die-casting part. After the test is completed, the second motor 8 rotates in the opposite direction, disengaging the support block 11 from the lifting plate 19. Subsequently, the first cylinder 13 extends, lifting and driving the drive roller 14 to transport the large die-casting part, completing the unloading process.
