Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to upsetting test technology, specifically a multi-station sample delivery mechanism for upsetting process. Background Technology

[0002] Upsetting tests on metallic materials involve applying pressure along the axial direction of the metal sample at room temperature or under hot conditions to compress the sample. This tests the metal's ability to withstand upsetting plastic deformation at a specified forging ratio and reveals surface defects. It is primarily used to study the quality of metallic materials during mass production of molded parts.

[0003] Upsetting testing machines and rapid upsetting testing machines are commonly used devices for upsetting tests. However, these devices generally only have one station, which cannot meet the needs of rapid testing of batch products. Especially in the hot upsetting process, the single-station upsetting test will have a large temperature difference for metal parts taken out from the same batch, which will affect the accuracy of the test. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-station sample feeding mechanism for upsetting process. This multi-station sample feeding mechanism for upsetting process aims to solve the technical problem that the large temperature difference in the hot upsetting process of the existing single-station upsetting test machine affects the accuracy of the test.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-station sample feeding mechanism for upsetting process includes a frame, a worktable at the lower part of the frame, and an equipment platform at the upper part of the frame. A drive device is mounted on the upper side of the equipment platform, and an equipment hole is provided in the middle of the equipment platform. The output shaft of the drive device passes downward through the equipment hole and extends to the lower part of the equipment platform. A pressing head is provided at the lower end of the output shaft of the drive device. Two first slide rails are arranged parallel to each other on the upper side of the worktable along its length. A pressing plate is mounted above the two first slide rails and below the pressing head. Two first sliding blocks are provided at the bottom of the pressing plate, and each first sliding block has a first sliding groove at its bottom. The first slide rails are respectively fitted into the first sliding grooves. The sliding groove and the first slide rail form a sliding pair. A second slide rail is provided along the extension line of one end of any of the first slide rails. At least two cylinders are provided above the second slide rails. A second sliding block is provided at the bottom of any of the cylinders. A second sliding groove is provided at the bottom of the second sliding block. The second slide rail is fitted in the second sliding groove. The second slide rail and the second sliding groove form a sliding pair. A first support platform is provided at the bottom of the second slide rail. The first support platform is connected to one side of the worktable. The piston rod of any of the cylinders faces the lower pressure plate. In any two adjacent cylinders, the front end of the output shaft of the rear cylinder is connected to the tail end of the front cylinder. The front end of the output shaft of the foremost cylinder is connected to one side of the lower pressure plate. The piston rod of any of the cylinders shown is parallel to the second slide rail shown.

[0007] Furthermore, the number of cylinders is three.

[0008] Furthermore, the other end of the first slide rail extends to the outside of the worktable, and a second support platform is provided on the other side of the worktable, with the second support platform located below the first slide rail.

[0009] Furthermore, the frame also includes a base and supports. The base is located on the lower side of the workbench, and there are four supports, which are positioned between the workbench and the equipment platform.

[0010] Working principle:

[0011] The test specimens are placed on the lower pressure plate in sequence. Multiple cylinders push the lower pressure plate in stages, pushing the specimens on the lower pressure plate to the bottom of the lower pressure head in sequence. The driving device pushes the lower pressure head downward to apply pressure to the specimen.

[0012] Compared with the prior art, the advantages of this utility model are: multiple samples can be placed at one time to quickly complete upsetting; during hot upsetting, the sample temperature drop is small, which improves the accuracy of the test. Attached Figure Description
