Polymer plate folding test equipment with positioning mechanism

Abstract

The application provides a high polymer plate folding test equipment with a positioning mechanism, and relates to the technical field of plate processing equipment. The equipment comprises a support body, fixed seats are arranged on the left and right sides of the top of the support body, a follow-up rotating shaft is rotatably arranged on the fixed seat, and a limiting piece is fixedly arranged on the front end of the follow-up rotating shaft. The two ends of the plate to be tested can be automatically lifted after the middle part of the plate is pressed, effectively avoiding the interference of the traditional positioning structure on the folding rate test accuracy of the plate caused by the limitation of the free deformation of the end part of the plate, ensuring the authenticity of the test data, and solving the problem that the two ends of the plate should naturally be lifted in a V shape after the middle part of the plate is stressed to truly reflect the folding deformation process of the plate. However, the rigid constraint of the fixed positioning mechanism on the two ends of the plate limits the free lifting of the end part of the plate, which easily leads to the unexpected bending or breaking of the plate at the clamping position of the positioning mechanism.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plate processing equipment, and particularly relates to a high polymer plate folding resistance testing equipment with a positioning mechanism. BACKGROUND

[0002] ‌High polymer plates are widely used in many fields such as chemical industry and building materials due to their multiple excellent properties such as wear resistance, corrosion resistance and high toughness. In order to strictly control the factory quality and ensure that the performance meets the actual use requirements, the folding resistance of the high polymer plate is usually detected by a folding resistance testing equipment after the production is completed, so as to accurately evaluate the product quality.

[0003] In the operation process of the existing high polymer plate folding resistance testing equipment, in order to prevent the plate from shifting during testing, a positioning mechanism is generally used to fix both ends of the plate, and then a stamping mechanism is used to press downward from the middle of the plate to complete the test. However, the positioning mechanism of the existing equipment is mostly fixed design. According to the physical characteristics of the folding resistance test of the plate, when the stamping mechanism presses the middle of the plate, the two ends of the plate should naturally be V-shaped and raised after being stressed in the middle, so as to truly reflect the folding deformation process. However, due to the rigid constraint of the fixed positioning mechanism on both ends of the plate, the end of the plate cannot be freely raised, which not only easily leads to unexpected bending or breaking of the plate at the clamping position of the positioning mechanism (which does not match the actual folding failure scenario), but also interferes with the test data due to the limited deformation of the end, resulting in a large deviation of the folding resistance test result of the plate, and the real folding resistance of the plate cannot be accurately reflected. SUMMARY

[0004] The present application relates to the technical field of plate processing equipment, and particularly relates to a high polymer plate folding resistance testing equipment with a positioning mechanism.

[0006] Wherein, the inner end of the stress groove is of an inclined structure; the front end of the transmission rod is of an inclined structure; the inclined surface of the transmission rod is in contact with the inclined surface of the stress groove; one end of a spring B is embeddedly installed on the front side of the driven push disc; the other end of the spring B is embeddedly installed on the rear side wall of the limiting piece; the bending push piece is located above the to-be-tested plate; the connecting rod is also slidingly installed on the supporting plate; the transmission column is of a cylindrical structure.

[0007] Wherein, the guide rod is of a cylindrical structure; one end of a spring C is embeddedly installed in the inner part of the transmission push piece; the other end of the spring C is embeddedly installed on the rear side wall of the supporting plate; the transmission groove is composed of an inclined groove and a vertical groove, and the lowest end of the inclined groove is in communication with the highest end of the vertical groove; the transmission column is also slidingly installed in the inner part of the transmission groove.

[0008] Wherein, the push ring is of a circular ring structure; the push ring is also slidingly installed on the follow-up rotating shaft; the push ring is located at the rear side of the driven push disc; force-reducing balls are rotatably installed on the front side of the push ring; the outer wall of the force-reducing balls is in contact with the rear side wall of the driven push disc; when the bending push cylinder moves downward with the bending push piece, the bending push piece will move downward with the connecting rod and the transmission column.

[0009] The transmission column moves downward and converts the downward force into forward force to provide the transmission plate and the transmission push piece with the forward force through the inclined groove part of the transmission groove; the transmission push piece moves forward, and the push ring and the flow resistance ball on the transmission push piece push the driven push disc forward; the inclined surface of the transmission rod on the driven push disc pushes the inclined surface of the force receiving groove when the driven push disc moves forward; the inclined surface of the force receiving groove moves inward with the clamping piece after being pushed.

[0011] 1. The folding test equipment is provided with a limiting piece, and the two ends of the plate to be tested are clamped in the limiting piece during use. When the middle part of the plate to be tested is pushed and pressed by the bending push piece, the two ends of the plate to be tested can be automatically lifted due to the fact that the limiting piece is installed on the fixed seat through the follow-up rotating shaft, so that the interference on the folding rate test accuracy of the plate caused by the traditional positioning structure which limits the free deformation of the end part of the plate is effectively avoided, and it is ensured that the test data can truly reflect the folding resistance performance of the plate.

[0012] 2. The folding test equipment is also provided with a clamping piece. When the bending push cylinder drives the bending push piece to move downward, the transmission push piece and the push ring will forwardly push the driven push disc and the transmission rod under the cooperation of multiple components; the transmission rod is immediately matched with the force receiving groove, and drives the entire clamping piece to move inward, so that the limiting and fixing of the two ends of the plate to be tested are realized through the inward movement of the clamping piece, thereby ensuring the position stability of the plate to be tested in the whole folding test process and preventing the test deviation caused by the displacement of the plate.
