Description
Technical Field
[0001] The present invention relates to the technical field of rubber cloth inspection, and specifically to a rotorless curing meter and method for rubber cloth testing. Background Art
[0002] A rotorless curing meter is an important instrument used to detect the vulcanization characteristics of rubber in industries such as rubber processing. A rubber specimen is placed in an almost completely enclosed mold cavity and maintained at the test temperature. The mold cavity has upper and lower parts, and the lower part moves linearly back and forth slightly (oscillates), and the oscillation causes shear strain in the specimen.
[0003] In a conventional rotorless curing meter, the middle and lower parts only oscillate along a specific trajectory. In actual use, rubber products may be subjected to various forces in different directions and forms. However, only oscillating along a specific trajectory can only simulate a single direction or a specific form of shear stress, making it difficult to comprehensively and truly reflect the complex stress state that rubber bears under actual working conditions, resulting in a deviation between the test results and the actual use situation, and it is impossible to accurately evaluate the performance of rubber products in a complex environment.

Apply shear force to the rubber cloth from different angles. Each time the rubber cloth is tested, the rubber cloth is replaced. The pulling force angles of the rubber cloth by the shear force pulling member are different, but the direction of the force is a horizontal pulling force. The rubber cloth usually has a certain directionality, and its mechanical properties in different directions may vary. By applying shear force from different angles, the shear strength, elastic modulus and other performance indicators of the rubber cloth in all directions can be comprehensively detected, accurately revealing its anisotropic characteristics, providing more detailed data support for the application and design of the material. In actual use, the rubber cloth often receives forces from different directions, rather than simple unidirectional stretching or shearing. By changing the shear force angle, the complex mechanical environment that the rubber cloth bears in different application scenarios can be simulated, making the test results closer to the actual use situation and providing a more reliable basis for the design and selection of products.
[0018] 2. The piston rods of multiple second electric push rods are used to push the structure composed of the clamping plate and the L-shaped angle iron to move, and the structure composed of the L-shaped angle iron and the clamping plate is used to push the rubber cloth to move, so as to realize the positioning of the rubber cloth and ensure that the rubber cloth is located at the center position of the upper surface of the shear force pulling member. Making the rubber cloth located at the center position of the upper surface of the shear force pulling member can ensure that the shear force received by the rubber cloth is evenly distributed during the detection. If the position of the rubber cloth is offset, it may cause excessive or insufficient local stress, affecting the authenticity and accuracy of the detection data. Precise positioning can make the shear force act evenly on the rubber cloth, resulting in a more reliable tensile test result. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0034] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0035] Please refer to Figures 1 to 14 , the present invention provides a technical solution: a rotorless curing meter for rubber cloth testing and its method, including a curing meter body 1, two vertical guide rods 2 are vertically installed on the curing meter body 1, an upper movable pressing plate 3 is movably installed along the axial direction on the two vertical guide rods 2, and a lower fixed pressing plate 4 is fixedly installed along the axial direction. The vertical guide rods 2 are used for guiding the up and down movement of the upper movable pressing plate 3; The upper movable pressing plate 3 and the lower fixed pressing plate 4 form a fully enclosed structure for rubber cloth experiments; A shear force pulling member 5 is movably installed in the lower fixed pressing plate 4, and a bottom fixed plate 6 is provided at the bottom of the shear force pulling member 5 for support and fixation; A first driving mechanism 7 is provided below the bottom fixed plate 6, and the first driving mechanism 7 is used to control the bottom fixed plate 6 and the shear force pulling member 5 to reciprocate slightly along a preset direction; The control system can precisely control the start, stop, rotation speed, and rotation direction of the driving part, and then accurately manipulate parameters such as the moving speed, moving distance, and reciprocating motion frequency of the bottom fixed disk 6 and the shear force pulling part 5. Through programming settings, the control system can make the driving mechanism move the bottom fixed disk 6 and the shear force pulling part 5 reciprocally in a specific direction according to a certain time interval and speed pattern. The distance of each movement and the staying time can be precisely adjusted according to experimental requirements.
[0036] A second driving mechanism 8 is arranged below the first driving mechanism 7, and the second driving mechanism 8 is used to change the reciprocating movement direction of the first driving mechanism 7, the bottom fixed disk 6 on the first driving mechanism 7, and the shear force pulling part 5.
[0037] The reciprocating movement distance of the shear force pulling part 5 within the lower fixed compression disk 4 is less than the size of the gap between the lower fixed compression disk 4 and the shear force pulling part 5.
[0038] A first electric push rod 9 is arranged at the top of the vulcanizer body 1, and the piston rod of the first electric push rod 9 is fixedly installed at the central position of the top of the upper movable pressing disk 3; The first electric push rod 9 exerts a thrust and a pull force on the upper movable pressing disk 3 along the axial direction of the vertical guide rod 2.
[0039] The vertical guide rod 2 plays a guiding role for the upper movable pressing disk 3. When the upper movable pressing disk 3 moves along the axial direction of the vertical guide rod 2, the vertical guide rod 2 can limit its movement trajectory, enabling it to move only in the vertical direction, ensuring the movement accuracy and stability of the upper movable pressing disk 3. The thrust and pull force exerted by the first electric push rod 9 are along the axial direction of the vertical guide rod 2, cooperating with the guiding role of the guide rod, enabling the upper movable pressing disk 3 to accurately move in the predetermined direction.
[0040] The first driving mechanism 7 includes an assembly frame 701 fixedly installed on the vulcanizer body 1. A first servo motor 702 is fixedly installed at the central position of the assembly frame 701, and an elliptical pressure wheel 703 is fixedly installed on the output shaft of the first servo motor 702; The upper surface of the assembly frame 701 is provided with a mounted guide rail 704. A telescopic pressure rod 705 is movably installed within the mounted guide rail 704. The telescopic pressure rod 705 is fixedly installed at the corresponding position at the bottom of the bottom fixed disk 6. A buffer spring 706 that exerts a reset elastic force on the telescopic pressure rod 705 is installed between the telescopic pressure rod 705 and the mounted guide rail 704.
[0041] When the bottom fixed plate 6 is subjected to external force from above (such as shear force pulling member 5), it will drive the telescopic pressure rod 705 to move along the mounting guide rail 704. During this process, the telescopic pressure rod 705 will compress the buffer spring 706. The elastic potential energy of the buffer spring 706 will gradually increase, playing a role in buffering and absorbing energy, thereby reducing the impact of the external force on the entire structure. When the external force disappears, the buffer spring 706 will try to return to its original shape due to the stored elastic potential energy, thereby applying a reset elastic force to the telescopic pressure rod 705. This elastic force will push the telescopic pressure rod 705 to move along the mounting guide rail 704, so that the bottom fixed plate 6 returns to its original position, thereby realizing the reset function of the entire structure.
[0042] A positioning seat 707 is fixedly installed in the mounting guide rail 704 , and an anti-skid wheel 708 is provided on the upper surface of the positioning seat 707 . The anti-skid wheel 708 is rollingly connected to the telescopic pressure rod 705 . The positioning seat 707 is located in a groove body opened on the telescopic pressure rod 705 .
[0043] The second driving mechanism 8 includes a positioning card 801, which is fixedly mounted on the outer wall of the first driving mechanism 7, and the positioning card 801 is distributed in a circular array with the center of the assembly frame 701 as the array center, and an assembly ring 802 is arranged below the assembly frame 701, and an elastic positioning piece 803 is arranged above the assembly ring 802 and distributed in a circular array with the center of the assembly ring 802 as the array center; The number of the elastic positioning pieces 803 corresponds to the number of the positioning clamps 801, and the elastic positioning pieces 803 are engaged at the corresponding positions at the bottom of the positioning clamps 801; A second servo motor 804 is disposed in the vulcanizer body 1 , and the output shaft of the second servo motor 804 is transmission-connected with the first servo motor 702 for changing the reciprocating angle of the bottom fixing plate 6 on the assembly ring 802 .
[0044] The reciprocating angle of the bottom fixing plate 6 can be flexibly changed by the cooperation of the second servo motor 804 and the first servo motor 702. In the rubber vulcanization experiment or other related tests, different experimental purposes may require the bottom fixing plate 6 to reciprocate at different angles to simulate different actual working conditions or test the performance of rubber under different force angles. This adjustable angle setting can greatly improve the experimental adaptability of the vulcanizer and meet diverse experimental needs.
[0045] A heating mechanism 10 is provided in both the upper movable pressing plate 3 and the shear force pulling member 5, and the heating mechanism 10 is used to heat the upper movable pressing plate 3 and the shear force pulling member 5; The heating mechanism 10 includes two end plates 1001, and a connecting rod 1002 is arranged between the two end plates 1001 for connection. Structures composed of heating tapes 1003 and heating fins 1004 are installed on the upper movable pressure plate 3 and the end plate 1001 on the side close to the shear force pulling member 5.
[0046] A plurality of positioning mechanisms 11 are arranged around the lower fixed pressure plate 4 of the vulcanization instrument body 1, and the plurality of positioning mechanisms 11 are distributed in an annular array centered on the lower fixed pressure plate 4; The positioning mechanism 11 includes a second electric push rod 1101 fixedly installed on the vulcanization instrument body 1. An L-shaped angle iron 1102 is fixedly installed on the piston rod of the second electric push rod 1101. A clamping plate 1103 is fixedly installed on the L-shaped angle iron 1102 through a locking bolt 1104. The clamping plate 1103 and the locking bolt 1104 form a pushing member corresponding to the rubber cloth.
[0047] When positioning the rubber cloth is required, the control system sends an instruction to the second electric push rod 1101, the driving motor starts to work, the motor drives the lead screw to rotate, and the piston rod makes a linear motion. If it is necessary to push the rubber cloth, the piston rod of the second electric push rod 1101 extends, driving the L-shaped angle iron 1102 to move forward, and the clamping plate 1103 fixed on the L-shaped angle iron 1102 also moves forward accordingly, thereby pushing the rubber cloth to the specified position; if it is necessary to retract the pushing member, the piston rod retracts, driving the entire pushing member back to the initial position.
[0048] A method for using a non-rotor vulcanization instrument for rubber cloth testing includes the following steps: S1: According to the tensile test requirements of the rubber cloth, adjust the angle of the shear force pulling member in the lower fixed pressure plate, and the output shaft of the second servo motor changes the angle of the shear force pulling member.
[0049] S2: Place the rubber cloth to be tested on the upper surface of the shear force pulling member in the lower fixed pressure plate, and push the rubber cloth to move and position it through the piston rods of a plurality of second electric push rods. The rubber cloth is located at the center position on the upper surface of the shear force pulling member.
[0050] S3: Heat the end plate 1001 through the structure composed of the clamping plate 1103 and the locking bolt 1104, and the structure composed of the upper movable pressure plate 3 and the vertical guide rod 2 seals the rubber cloth to achieve sealed heating of the rubber cloth.
[0051] S4: Drive the elliptical pressure wheel 703 to rotate through the output shaft of the first servo motor 702. The elliptical pressure wheel 703 drives the shear force pulling member 5 to reciprocate in the lower fixed pressure plate 4. The shear force pulling member 5 applies a pulling force to the bottom of the rubber cloth from below to detect the shear strain of the vulcanized cloth.
[0052] Working principle: Step 1: According to the stretching detection requirements of the rubber cloth, detect the effect of the rubber cloth under shear force without setting an angle. Each time the rubber cloth is detected, the rubber cloth is replaced. The pulling angles of the shear force pulling member on the rubber cloth are different, but the rubber cloth has unidirectional vibration. The unidirectional vibration can generate stable shear strain. Compared with traditional detection equipment, the function of changing the angle of the unidirectional vibration member is added to detect the difference in the unidirectional vibration received by different positions of the rubber cloth, and to adjust the angle of the shear force pulling member 5 in the lower fixed compression plate 4. The rotation angle of the output shaft of the second servo motor 804 can be controlled by the machine to achieve the control of the rotation angle of the bottom fixed plate 6 and the structure above the bottom fixed plate 6. The output shaft of the second servo motor 804 drives the assembly frame 701 to rotate, thereby driving the shear force pulling member 5 above the assembly frame 701 to rotate in the lower fixed compression plate 4. Every time the shear force pulling member 5 rotates 9 degrees by the first electric push rod, the positioning card member 801 presses the elastic positioning piece 803, causing the elastic positioning piece 803 to deform. After the elastic positioning piece 803 deforms, the positioning card member 801 is engaged in the next elastic positioning piece 803 to achieve the positioning and fixing after the rotation of the assembly frame 701.
[0053] Step 2: Place the rubber cloth to be tested on the upper surface of the shear force pulling member 5 in the lower fixed compression plate 4. The piston rods of multiple second electric push rods 1101 push the L-shaped angle iron 1102 to move. When the L-shaped angle iron 1102 moves, it drives the structure composed of the clamping plate 1103 and the L-shaped angle iron 1102 to move. The L-shaped angle iron 1102 lifts the edge of the rubber cloth, and the edge of the rubber cloth is engaged in the structure composed of the L-shaped angle iron 1102 and the clamping plate 1103. The structure composed of the L-shaped angle iron 1102 and the clamping plate 1103 pushes the rubber cloth to move, thereby realizing the positioning of the rubber cloth and ensuring that the rubber cloth is located at the central position on the upper surface of the shear force pulling member 5.
[0054] Step 3: Heat the end plate 1001 through the structure composed of the clamping plate 1103 and the locking bolt 1104. The piston rod of the first electric push rod 9 drives the upper movable compression plate 3 to descend. The upper movable compression plate 3 moves on the vertical guide rod 2. The upper movable compression plate 3 approaches the vertical guide rod 2. The structure composed of the upper movable compression plate 3 and the vertical guide rod 2 seals the rubber cloth to achieve the sealed heating of the rubber cloth to assist the subsequent detection of the rubber cloth.
[0055] Step 4: Drive the elliptical pressure wheel 703 to rotate through the output shaft of the first servo motor 702, apply pressure to the end of the telescopic pressure rod 705 through the rotation of the elliptical pressure wheel 703. After the end of the telescopic pressure rod 705 is pressed, transfer the pressure to the buffer spring 706. Assist the reset of the telescopic pressure rod 705 through the elastic force generated by the deformation of the buffer spring 706. The elliptical pressure wheel 703 pushes the telescopic pressure rod 705 to reciprocate within the mounting guide rail 704, thereby driving the shear force pulling member 5 to move radially within the lower fixed pressure receiving disc 4. The shear force pulling member 5 applies a pulling force to the bottom of the rubber cloth from below to detect the shear strain of the vulcanized cloth.
[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
