Description

Technical Field

[0001] The invention relates to the field of material testing, and in particular to a protective universal material testing machine. Background Art

[0002] With the development of science and technology, people have higher and higher requirements for the durability of materials. For example, after some non-metallic materials are produced, they need to be bent to detect the bending properties of non-metallic materials. In order to test the ultimate bending properties of the test materials, force is often applied to the test materials until the test materials bend and break during the test. The break may produce a large amount of debris, which will produce obvious splashing due to the collapse of the material. The existing technology for the protection of the test process is generally to surround the entire test area of ​​the test machine through a large-scale isolation cover. Although it can prevent the debris from splashing into the external environment, the isolation cover is formally surrounded together with some structures of the test machine itself. The fragments splashed by the collapse will impact the inner wall of the protective cover, the test machine table and other locations, resulting in secondary splashing, resulting in the probability that the debris will splash onto the component structure of the test machine, affecting the operation and experiment of the test machine, and increasing the maintenance frequency of the test machine itself. Summary of the invention

[0003] In order to overcome the shortcomings of existing testing equipment that lacks a corresponding collection structure and that debris often splashes everywhere, resulting in a probability that the debris will splash onto the component structure of the testing machine, affecting the operation and experiment of the testing machine and increasing the maintenance frequency of the testing machine itself, the present invention provides a protective universal material testing machine.

[0005] More preferably, the fixing components include a mounting frame, a mounting plate and a pressing plate; the mounting frame is fixedly connected to the testing machine; the mounting plate is fixedly connected to the mounting frame; a receiving groove for receiving the material to be tested is opened on the mounting plate, and the receiving groove is connected to the collection frame; a plurality of pressing plates are connected to the mounting plate, and the pressing plates are used to fix the material to be tested; the mounting frame is fixedly connected to all the connecting plates.

[0006] More preferably, the rubber rod is arranged in an inclined upward posture.

[0007] More preferably, the collecting frame is arranged in an inverted cone structure that is larger at the top and smaller at the bottom.

[0008] More preferably, a cleaning assembly is also included, which includes a cover and a nozzle; the cover is fixedly connected to the pressure head; a plurality of nozzles are penetrated on the collection frame; and the rubber pad is penetrated by the nozzle.

[0009] More preferably, a plurality of spring pieces in an annular array are arranged on the cover shell, and the cover shell has deformation capability.

[0013] More preferably, the surface of the rubber pad is coated with a coating that reduces friction.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The present invention blocks flaky debris and strip-shaped debris by a rubber rod to reduce the number of collisions between the flaky debris and strip-shaped debris, and the rubber rod is set to be tilted upward, which can reduce the probability of the flaky debris and strip-shaped debris hooking on the rubber rod and then detaching, and can also increase the bending angle of the rubber rod, and improve the ability of the rubber rod to attract the kinetic energy of the flaky debris and strip-shaped debris to splash, so that the debris stops moving in the shortest possible time;

[0016] 2. The present invention uses a nozzle to inject airflow to disturb the flaky debris and strip debris caught on the rubber rod, so that the flaky debris and strip debris limited thereon are separated from the rubber rod and fall onto the electric door, so there is no need to manually use a toggle lever to toggle the rubber rod. The debris, flaky debris and strip debris can be preliminarily distinguished through the filter screen, thereby reducing the labor intensity of manually separating the mixed components and simplifying the collection work;

[0017] 3. The rubber rod in the bent state has less obstruction to flaky debris and strip-shaped debris. Flaky debris and strip-shaped debris are more likely to slide along the rubber rod under the disturbance of airflow and detach from the rubber rod from the free end of the rubber rod. After a certain period of time, the electromagnet is controlled to stop energizing so that the electromagnet loses its magnetism. Under the elastic force of the rubber rod, the rubber rod drives the metal sleeve to rebound and make the rubber rod shake. The flaky debris and strip-shaped debris detach from the limit of the rubber rod by shaking, further cleaning the flaky debris and strip-shaped debris at the upper limit of the rubber rod, simplifying the debris separation work.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1

[0028] A protective universal material testing machine, such as Figure 1-4 As shown, it includes a testing machine 1, a connecting plate 7 and a fixing component; the fixing component is installed on the testing machine 1; two symmetrically arranged connecting plates 7 are fixedly connected to the fixing component; a sliding plate 3 is slidably connected to the body of the testing machine 1; and a pressure head 4 is fixedly connected to the sliding plate 3;

[0029] It also includes a collection frame 8, a rubber pad 9, a rubber rod 10 and an electric door 12; all the connecting plates 7 are fixedly connected to the collection frame 8; a rubber pad 9 is installed on the inner wall of the collection frame 8; a number of rubber rods 10 are fixedly connected to the rubber pad 9; and two symmetrically arranged electric doors 12 are rotatably connected to the collection frame 8.

[0030] The fixing parts include a mounting frame 2, a mounting plate 5 and a pressing plate 6; the mounting frame 2 is fixedly connected to the testing machine 1; the mounting plate 5 is bolted to the mounting frame 2; a receiving groove for receiving the material to be tested is opened on the mounting plate 5, and the receiving groove is connected to the collecting frame 8; two symmetrically arranged pressing plates 6 are connected to the mounting plate 5, and the pressing plates 6 are used to fix the material to be tested; the mounting frame 2 is fixedly connected to all the connecting plates 7.

[0031] The rubber rod 10 is disposed in an inclined upward posture.

[0032] The collecting frame 8 is arranged in an inverted cone-shaped structure with a larger upper portion and a smaller lower portion, and is used to collect the debris and fragments generated by the fracture.

[0033] First, the staff installs the protective universal material testing machine at the location where it is needed, and then the staff places the test material on the mounting plate 5, and then the staff tightens the limit bolts on the pressure plate 6 to make the pressure plate 6 contact and fix the test material, and then controls the test machine 1 to drive the sliding plate 3 to slide downward, and the sliding plate 3 drives the pressure head 4 to move downward to apply pressure to the test material on the mounting plate 5 until the test material breaks, and collects the change data of the test material itself during the pressure application process, and the debris generated by the broken test material moves downward into the collection frame 8, and the debris is allowed to enter the collection frame 8 by setting up a collection frame 8 at the bottom, and even if debris splashing occurs, it will basically only move inside the collection frame 8, and the debris is avoided from splashing onto the component structure of the test machine itself to the greatest extent, thereby greatly reducing the possibility of debris affecting the normal operation of the test machine, and the test machine does not require high-frequency maintenance, which improves the safety of equipment operation; the debris entering the collection frame 8 will contact the rubber pad 9 and the rubber rod 10, and the rubber pad 9 buffers the splashing debris and reduces the number of rebounds caused by hitting the inner wall of the collection frame 8, and the flaky debris and strip debris are more In the first step, due to its large size and length, it is easier to hook onto the surface of the rubber rod 10. The rubber rod 10 is limited by the bendable characteristics of the rubber rod 10 itself, and the kinetic energy of the splashing of the flaky debris and the strip-shaped debris can be absorbed. The flaky debris and the strip-shaped debris are blocked by the rubber rod 10 to reduce the number of collisions between the flaky debris and the strip-shaped debris. The rubber rod 10 is set to be tilted upward, which can reduce the probability of the flaky debris and the strip-shaped debris hooking on the rubber rod 10 and then detaching, and can also increase the bendable angle of the rubber rod 10, thereby improving the ability of the rubber rod 10 to absorb the flaky debris and the strip-shaped debris. The ability of the flaky debris and strip-shaped debris to splash kinetic energy; and then stop the movement of the flaky debris and strip-shaped debris in the shortest possible time, and limit the flaky debris and strip-shaped debris by the rubber rod 10. These flaky debris and strip-shaped debris are more easily confined in the area where the rubber rod 10 is located, which is convenient for subsequent collection work. After completing a test, the electric door 12 is controlled to open, and then the staff uses the toggle rod to toggle the rubber rod 10 to make the flaky debris and strip-shaped debris on the rubber rod 10 break away from its limit, and then discharge them through the channel opened by the electric door 12.

[0034] Example 2

[0035] On the basis of the above-mentioned embodiment 1, Figure 5-6 As shown, a cleaning assembly is also included, which includes a cover 101 and a nozzle 102; the cover 101 is fixedly connected to the outer periphery of the pressure head 4; four nozzles 102 distributed in a rectangular shape are penetrated on the collecting frame 8; and the rubber pad 9 is penetrated by the nozzle 102.

[0036] Four spring pieces 101a in a circular array are arranged on the cover 101. The cover 101 has a deformation capability to facilitate cleaning of the generated debris.

[0037] The nozzle of the nozzle 102 is oriented in a direction parallel to the surface of the rubber pad 9 so that the ejected airflow flows along the rubber pad 9 .

[0038] The electric door 12 is provided with a filter 12a for filtering debris generated by the separation test.

[0039] In the process of the sliding plate 3 driving the pressure head 4 to move downward to apply force to the test material, the pressure head 4 drives the cover 101 to contact the mounting plate 5, and the cover 101 isolates the fragments of the test material splashing upward to prevent the debris from splashing outside the equipment, so that the debris is limited to a certain range, reducing the difficulty of subsequent collection; then the spring piece 101a on the cover 101 is compressed, and then the test machine 1 is controlled to drive the sliding plate 3 to move upward, the sliding plate 3 drives the pressure head 4 to move upward, and the pressure head 4 drives the cover 101 to move upward, so that the compressed spring piece 101a is restored, that is, the spring piece 101a drives the cover 101 to shake, so that the debris adhering to the cover 101 is separated and falls onto the mounting plate 5, which is convenient for the staff to collect the debris;

[0040] Before collecting the debris in the collection frame 8, personnel are required to connect the external gas injection equipment with the nozzle 102. After completing a test, the external gas injection equipment is controlled to inject airflow into the nozzle 102, and then it is ejected through the nozzle 102. The airflow helps to disturb the flaky debris and strip-shaped debris blocked on the rubber rod 10, so that the flaky debris and strip-shaped debris limited thereon break away from the rubber rod 10 and fall onto the electric door 12. There is no need for manual labor to use a toggle lever to toggle the rubber rod 10. The debris can be preliminarily distinguished from the flaky debris and strip-shaped debris through the filter screen 12a, thereby reducing the workload of manual separation of the mixed components and simplifying the collection work.

[0041] Example 3

[0042] Based on the above embodiment 2, Figure 7As shown, a separation component is also included, which includes a metal sleeve 11 and an electromagnet 201 ; a plurality of electromagnets 201 are provided on the rubber pad 9 ; and each rubber rod 10 is covered with a metal sleeve 11 .

[0043] The surface of the rubber pad 9 is coated with a friction reducing coating to make it easier for the flaky debris and strip-shaped debris to slide down.

[0044] In the process of the nozzle 102 ejecting airflow to disturb the flaky debris and strip-shaped debris, the electromagnet 201 is controlled to be energized to generate magnetism, and the metal sleeve 11 on the rubber rod 10 is adsorbed to make the rubber rod 10 bend downward, and the free end of the rubber rod 10 is directed toward the electric door 12. The rubber rod 10 in the bent state has less obstruction to the flaky debris and strip-shaped debris, and the flaky debris and strip-shaped debris are more likely to slide along the rubber rod 10 under the disturbance of the airflow and separate from the rubber rod 10 from the free end of the rubber rod 10. After a certain period of time, the electromagnet 201 is controlled to stop energizing to make the electromagnet 201 lose its magnetism. Under the elastic force of the rubber rod 10, the rubber rod 10 drives the metal sleeve 11 to rebound, so that the rubber rod 10 shakes. The flaky debris and strip-shaped debris are separated from the limit of the rubber rod 10 by shaking, and the flaky debris and strip-shaped debris at the upper limit of the rubber rod 10 are further cleaned, thereby improving the simplicity of the debris separation work.
