Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of drop hammer test device, and particularly relates to a drop hammer test device for rapidly testing the quality of zinc alloy ingot. BACKGROUND

[0002] Due to the low melting point and good fluidity of zinc alloy, the zinc alloy is often used to press cast thin-walled parts. In the process of zinc alloy press casting, the quality of the alloy is crucial to the press casting forming, which requires the quality of the zinc alloy to be controlled from the source.

[0003] At present, in the national standards GB / T 13818 "Zinc Alloy for Die Casting", GB / T 13821 "Zinc Alloy Die Castings", and GB / T 8738 "Zinc Alloy Ingot for Casting", only the composition and surface quality of the zinc alloy ingot for die casting are required. However, in the actual production process, the downstream press casting enterprises find that under the same press casting process, when the mold is scattered and the toughness of the press castings is low, the zinc alloy ingot is also considered to have low toughness. This is because the impurities in the alloy ingot are high, and the zinc slag is not completely removed during the melting of the zinc alloy. When the alloy ingot is remelted, it is still wrapped in the alloy liquid and pressed into products, resulting in low toughness of the products, easy breaking, and even mold scattering during the press casting process.

[0004] In actual production, the zinc alloy press casting enterprises often use a simple way to judge the quality of the zinc alloy ingot. That is, a piece of zinc alloy ingot is placed on the ground, and another piece of zinc alloy ingot is used to impact the zinc alloy ingot on the ground from a certain height. If the zinc alloy ingot on the ground breaks, it is considered to have low toughness, that is, the alloy ingot is brittle, and the impurities in the alloy ingot are indirectly inferred. However, this method not only has safety hazards, but also has a simple and rough testing method. Moreover, the toughness and weight of different zinc alloy grades are different, and the test has a large contingency and lacks repeatability. SUMMARY

[0005] The purpose of the present application is to solve the problem that in actual production, the zinc alloy press casting enterprises often use a simple way to test the toughness of the zinc alloy ingot. That is, a piece of zinc alloy ingot is placed on the ground, and another piece of zinc alloy ingot is used to impact the zinc alloy ingot on the ground from a certain height. If the zinc alloy ingot on the ground breaks, it is considered to have low toughness, that is, the alloy ingot is brittle, and the impurities in the alloy ingot are indirectly inferred. However, this method not only has safety hazards, but also has a simple and rough testing method. Moreover, the toughness and weight of different zinc alloy grades are different, and the test has a large contingency and lacks repeatability.

[0006] To achieve the above objectives, the present invention employs the following technical solution: a drop hammer test device for rapidly inspecting the quality of zinc alloy ingots, comprising:

[0007] The base has several guide pillars and a zinc alloy ingot placement area. Guide pillar sleeves are fitted on the guide pillars. A hook is set on the top of the guide pillar sleeve, and a weight is set on the bottom of the guide pillar sleeve. A hammer is set on the bottom of the weight.

[0008] The beam is adjustable and connected between several guide posts, with hooks attached to it.

[0009] Furthermore, limit plates are provided on both sides of the base, and the zinc alloy ingot placement area is located between the limit plates.

[0010] Furthermore, the aforementioned base is provided with several fixing holes.

[0011] Furthermore, the guide post is provided with several vertically arranged mounting holes, and the two sides of the crossbeam are connected to the mounting holes.

[0012] Furthermore, the base is provided with a hollow hole, which is located in the middle of the zinc alloy ingot placement area.

[0013] Furthermore, the present invention also provides a rapid drop hammer test method for inspecting the quality of zinc alloy ingots, comprising the following steps:

[0014] S1: Fix the base of the test device to the ground, and put the guide column with weights and hammers onto the guide column of the test device;

[0015] S2: Install the crossbeam and attach the hooks on the guide post sleeve to the crossbeam;

[0016] S3: Place the zinc alloy ingot in the zinc alloy ingot placement area, with the center of the zinc alloy ingot suspended above the hollow hole.

[0017] S4: Remove the hook from under the beam, allowing the hammer with the weight to fall freely. The hammer hits the middle of the zinc alloy ingot. The toughness of the zinc alloy ingot is judged based on whether it breaks or its state after the impact, thereby indirectly judging whether its impurity content meets the requirements.

[0018] S5: Adjust the height of the crossbeam so that the hammerhead falls freely from different heights. Judge the toughness of the zinc alloy ingot based on whether it breaks or its condition after being impacted.

[0019] S6: Replace the hammer with different weights and perform free fall at different heights. Determine the toughness of the zinc alloy ingot based on whether it breaks or its condition after impact.

[0020] This invention provides a rapid drop hammer test device for inspecting the quality of zinc alloy ingots. It involves setting a guide column on a base, installing an adjustable-height crossbeam on the guide column, and fitting a sleeve around the guide column to allow it to move along the column. When no test is needed, a hook on the guide column sleeve is attached to the crossbeam. When a test is required, the zinc alloy ingot is placed on the base with its center suspended. The hook is removed from the crossbeam, allowing the weight of a weight to cause a hammer to fall freely, striking the center of the zinc alloy ingot. The test is performed based on whether the ingot breaks after the impact. The toughness of zinc alloy ingots can be determined by cracks or their condition, thereby indirectly determining whether the impurity content meets the requirements. In addition, mounting holes at different heights are set on the crossbeam, allowing the crossbeam to be installed at different heights as needed, allowing the hammer to fall freely. At the same time, different weights can be replaced with different hammers, enabling combined tests of multiple hammer weights and multiple crossbeam heights. This allows for drop hammer impact tests on different grades of zinc alloy ingots. Through this device and test method, the toughness of die-cast zinc alloys can be qualitatively tested, thereby determining whether the impurities are too high and whether they meet the requirements for downstream zinc alloy die casting.

[0021] Therefore, this embodiment has the following advantages compared to the prior art:

[0022] A rapid drop hammer test device for inspecting the quality of zinc alloy ingots solves the problem of a common, simplistic method used by zinc alloy die-casting companies to assess the strength and toughness of zinc alloy ingots in actual production. This method involves placing one zinc alloy ingot on the ground and allowing another ingot to fall freely from a certain height to impact the first ingot. If the ingot on the ground breaks, it is considered to have low strength and toughness, meaning it is brittle, and this indirectly infers the presence of impurities. However, this method not only poses safety hazards but is also crude and unreliable. Furthermore, given the differences in toughness and weight between different zinc alloy grades, this test method is highly unpredictable and lacks repeatability. Attached Figure Description
