Description

Technical Field

[0001] The present invention relates to the technical field of wear-resistant lining plate testing, and in particular, to a pendulum impact testing machine for wear-resistant lining plates. Background Art

[0002] Wear-resistant lining plates are a widely used type of protective plate, mainly installed in various equipment parts that are vulnerable to strong impact and wear by materials. The materials used for their production are mostly high manganese steel, alloy wear-resistant steel, rubber, ceramics, etc. These materials endow the wear-resistant lining plates with excellent wear resistance, and can effectively resist the friction and impact of materials on the inner wall of the equipment during transportation, grinding, etc., greatly extending the service life of the equipment, reducing the frequency of equipment maintenance and maintenance costs, and ensuring the continuity and stability of industrial production. However, the wear-resistant lining plate materials of existing bulk mineral transfer equipment (such as high manganese steel, ordinary alloy cast iron, etc.) face problems such as insufficient wear resistance, limited impact resistance, and short service life during long-term use. For this reason, a new wear-resistant lining plate material with excellent wear resistance, impact resistance, and long service life is provided based on a steel-based material system, introducing key alloying elements such as chromium, titanium, nickel, etc. for multi-element alloying design. Chromium elements form stable chromium carbide wear-resistant phases, titanium elements refine the grain structure, nickel elements enhance the chemical stability of the material, and an innovative preparation process of vacuum induction melting, powder metallurgy near-net shaping, and precise temperature control heat treatment is adopted. In order to verify the wear resistance and impact resistance of the new material, it is particularly necessary to carry out tests with a pendulum impact testing machine.

Since the one-way screw 14 is threadedly connected to the lifting plate 10, and the guide rod 11 plays a limiting and guiding role for the lifting plate 10, the lifting plate 10 will move up and down along the guide rod 11, thereby driving the folding protective cover 9 to expand or contract, thereby realizing protection of the test area and preventing the fragments of the pendulum impact from injuring the human body; A quick installation and disassembly assembly is provided on the outer wall of the fixing frame 29; The center of gravity adjustable component is arranged on the outer wall of the pendulum column 7 The adjustable component is arranged on the inner wall of the base 1 .

[0021] like Figures 4-6 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the quick installation and disassembly assembly includes a telescopic rod 27 uniformly fixedly connected to the outer wall of the fixing frame 29, the end of the telescopic rod 27 away from the fixing frame 29 is fixedly connected to the toggle plate 41, and the toggle plate 41 is slidably connected to the fixing frame 29, the outer wall of the fixing frame 29 is fixedly connected to the mounting seat 22, the outer wall of the mounting seat 22 is slidably connected to the connecting seat 23, the outer wall of the connecting seat 23 is fixedly connected to the pendulum body 24, and the outer walls of the connecting seat 23 and the mounting seat 22 are both provided with a limiting hole 40, The outer wall of the toggle plate 41 is fixedly connected with symmetrically distributed limit columns 25, and the limit columns 25 are slidably connected to the limit holes 40. When the pendulum body 24 needs to be installed, the toggle plate 41 is pushed through the hidden groove 26 to move the limit columns 25, align the connecting seat 23 with the mounting seat 22, and then the toggle plate 41 is released. Under the action of the strong spring A28, the limit columns 25 are inserted into the limit holes 40 to achieve rapid installation of the pendulum body 24. When disassembling, the toggle plate 41 is pushed again to disengage the limit columns 25 from the limit holes 40, and the pendulum body 24 can be removed.

[0022] like Figures 7-9As shown, as a preferred embodiment, on the basis of the above method, further, the center-of-gravity adjustable assembly includes a guide block 30 slidably connected to the outer wall of the pendulum column 7. A fixed disk 31 is fixedly connected to the outer wall of the guide block 30. A driving disk 32 is rotatably connected to the outer wall of the fixed disk 31.

Then, the counterweight block 33 is pushed to slide on the pendulum column 7 through the guide block 30, so as to change the position of the counterweight block 33 and achieve the adjustment of the center of gravity. When the appropriate position is adjusted, the driving disk 32 is rotated to drive the extrusion groove 34 to press its pressing rod 35 to drive the sliding limit block 39 to slide into the limit groove 20, thereby completing the limit fixation of the position of the counterweight block 33. During the rotation of the driving disk 32, the clamping block 37 is always pressed and the strong spring B38 is compressed, so that the clamping block 37 is disengaged from the card slot 36.

Since the bidirectional screw rod 16 is threadedly connected to the test clamping plates 18, and the test clamping plates 18 are slidably connected to the base 1 and the workbench 15, the two test clamping plates 18 will move towards or away from each other along the bidirectional screw rod 16, so as to support the wear-resistant lining body 19 according to its size for impact testing.

[0024] As Figure 2 shown, as a preferred embodiment, on the basis of the above method, further, symmetrically distributed guide rods 11 are fixedly connected to the outer wall of the mounting plate 8, and the guide rods 11 are slidably connected to the lifting plate 10.

[0029] like Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the outer wall of the toggle plate 41 is provided with symmetrically distributed hidden grooves 26 , and the hidden grooves 26 facilitate pulling the toggle plate 41 .

[0030] Specifically, when the pendulum impact tester for wear-resistant lining plate is used: the drive motor 13 is started, and its output end drives the one-way screw 14 to rotate. Since the one-way screw 14 is threadedly connected to the lifting plate 10, and the guide rod 11 plays a limiting and guiding role for the lifting plate 10, the lifting plate 10 will move up and down along the guide rod 11, thereby driving the folding protective cover 9 to expand or contract, thereby protecting the test area and preventing the fragments of the pendulum impact from injuring the human body; when the pendulum body 24 needs to be installed, the dial is pushed through the hidden groove 26.

Under the action of the strong spring A28, the limit column 25 is inserted into the limit hole 40, so that the pendulum body 24 can be quickly installed. When disassembling, the toggle plate 41 is pushed again to disengage the limit column 25 from the limit hole 40, and the pendulum body 24 can be removed; the driving plate 32 is rotated, and the extrusion groove 34 will push the sliding limit block 39 to slide in the limit groove 20 through the extrusion rod 35, releasing the limit block 39 and the limit groove 20. After the counterweight 33 is connected, the counterweight 33 is pushed to slide on the pendulum column 7 through the guide block 30, so as to change the position of the counterweight 33 and adjust the center of gravity. When it is adjusted to a suitable position, the driving disk 32 is rotated to drive the extrusion groove 34 to squeeze its extrusion rod 35 to drive the sliding limit block 39 to slide into the limit groove 20, thereby completing the limit fixation of the position of the counterweight 33. During the rotation of the driving disk 32, the card block 37 is always pressed and the strong spring B38 is compressed to make the card block 37 disengage from the card slot 36. When the limit block 39 is inserted into the limit groove At 20, release the block 37 and push the block 37 into the slot 36 under the action of the strong spring B38 to fix the position of the drive disk 32 and the counterweight block 33; turn the knob 17 to drive the bidirectional screw 16 to rotate. Since the bidirectional screw 16 is threadedly connected to the test clamp 18, and the test clamp 18 is slidingly connected to the base 1 and the workbench 15, the two test clamps 18 will move toward or in the opposite direction along the bidirectional screw 16, so that the wear-resistant lining body 19 can be supported according to its size for impact testing.
