Description

Technical Field

[0001] The utility model belongs to the technical field of impact toughness testing, in particular to a forging impact toughness testing device. Background Art

[0002] Forgings are metal workpieces or blanks made by forging. The characteristics of forgings include high strength, high plasticity, high toughness and high hardness. These characteristics make forgings very popular in the fields of industry and machinery manufacturing. They are widely used in many fields such as automobiles, railways, aviation, agricultural machinery, highways and bridges. During the production process of forgings, the impact toughness of forgings needs to be tested to evaluate their quality and performance.

[0003] After searching, the casting impact toughness tester disclosed in publication number CN218121643U includes a tester body, and an impact pendulum is rotatably installed on the top of the front end surface of the tester body. Although the above device helps to provide a certain protection for the impact pendulum when in use, when the staff is placing the workpiece, the impact pendulum may be accidentally operated by an outsider and fall, which may easily cause harm to the human body. Therefore, a forging impact toughness testing device is proposed. Utility Model Content

[0004] The utility model aims to provide a forging impact toughness testing device, which can avoid misoperation of the impact pendulum and the situation that the impact pendulum falls and injures workers when the workpiece is placed by moving the support plate to the rotation path of the impact pendulum, thereby improving the safety of use. At the same time, a baffle is installed between the first protective frame and the second protective frame, and the movement of the baffle is synchronized with the movement of the support plate, so that when the baffle is not closed, the impact pendulum cannot fall, which is convenient for people to operate and solves the existing technical problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] A forging impact toughness testing device comprises: a base, a tester body is mounted on the surface of the base, an impact pendulum for testing is mounted on one side of the tester body, a first protective frame and a second protective frame for protection are mounted on both sides of the base, a gap is provided between the first protective frame and the second protective frame for placing a workpiece, and a protective component for preventing the impact pendulum from falling is mounted above the first protective frame;

[0007] The protection assembly includes two first guide rails, which are both fixed above the first protection frame and symmetrically arranged, a group of first sliding blocks are slidably connected in the first guide rails, sliding rods are fixedly connected between the tops of the first sliding blocks in the same group, guide rods are fixedly connected to the tops of the sliding rods, and a support plate for supporting the impact pendulum is slidably connected between the two guide rods. By installing the support plate above the first protection frame, the support plate can be displaced. When placing the workpiece, the support plate can be moved to the rotation path of the impact pendulum, thereby avoiding misoperation of the impact pendulum, which may cause the impact pendulum to fall and injure the staff, thereby improving the safety of use.

[0008] As a further solution of the utility model, a second guide rail is fixedly connected to the surface of the second protective frame, a group of second sliders are slidably connected in the second guide rail, and a baffle for blocking the gap between the first protective frame and the second protective frame is fixedly connected between the second sliders. By installing the baffle between the first protective frame and the second protective frame, the movement of the baffle is synchronized with the movement of the support plate, and thus when the baffle is not closed, the impact pendulum cannot fall, making it convenient for people to operate.

[0009] As a further solution of the present invention, a connecting plate is fixedly connected between one of the first sliding blocks and one of the second sliding blocks.

[0010] As a further solution of the utility model, a first spring is provided on the circumference of the guide rod. The first spring is located between the slide rod and the support plate and is used to buffer the downward pressure of the support plate.

[0011] As a further solution of the utility model, a second spring is fixedly connected between the top of the guide rod and the surface of the support plate, and the second spring is used to buffer the upward pressure of the support plate.

[0012] As a further solution of the utility model, a handle is fixedly connected to one side of the baffle.

[0013] As a further solution of the utility model, a limiting plate for limiting the position of the second sliding block is fixedly connected to the bottom inner wall of the second guide rail.

[0014] In the utility model, when in use, the baffle is in a closed state, first the impact pendulum is raised, and then the baffle is opened. When opening, the baffle drives the second slider to move, and the second slider drives the slide rod and the support plate to move through the connecting plate, so that the support plate moves to the moving path of the impact pendulum, and then the workpiece is fixed above the base. During the placement of the workpiece, when the impact pendulum rotates accidentally, it can be blocked by the support plate to avoid direct fall and damage to the hands of the staff. At the same time, the first spring can be used to buffer the fall of the impact pendulum, thereby improving the service life of the device. After the workpiece is placed, the baffle is reset to block the gap between the first protective frame and the second protective frame. At the same time, the baffle is reset to drive the support plate to leave the moving path of the impact pendulum, and then the impact pendulum is operated to fall, and the first protective frame, the second protective frame and the baffle are used to block the broken workpiece, thereby improving the safety of use.

[0015] The embodiments of the present invention have the following beneficial effects:

[0016] In the utility model, by installing a support plate above the first protection frame, the support plate can be displaced. When placing a workpiece, the support plate can be moved to the rotation path of the impact pendulum, thereby avoiding the situation where the impact pendulum falls and injures workers due to misoperation of the impact pendulum, thereby improving the safety of use;

[0017] In the utility model, by installing a baffle between the first protection frame and the second protection frame, the movement of the baffle is synchronized with the movement of the support plate, and then when the baffle is not closed, the impact pendulum cannot fall, which is convenient for people to operate;

[0018] In the utility model, when placing a workpiece, the support plate can be moved to the rotation path of the impact pendulum, thereby avoiding misoperation of the impact pendulum, which may cause the impact pendulum to fall and injure workers, thereby improving the safety of use. At the same time, a baffle is installed between the first protective frame and the second protective frame, and the movement of the baffle is synchronized with the movement of the support plate, so that when the baffle is not closed, the impact pendulum cannot fall, which is convenient for people to operate.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
