Description

Technical Field

[0001] The invention relates to the technical field of conveyor belts, and more particularly to a steel wire conveyor belt die detection device. Background Art

[0002] At present, in the manufacturing process of conveyor belts, it is necessary to add steel wire ropes to the conveyor belts to improve the strength of the conveyor belts. However, in the production process, the vulcanization process of the rubber will directly affect the connection strength between the steel wire rope and the rubber. Poor vulcanization effect will lead to separation between the rubber and the steel wire rope, which will further affect the carrying capacity and service life of the conveyor belt. Therefore, the process parameters need to be verified before mass production. Specifically, the raw rubber is placed in a mold with a steel wire rope, and then the mold is placed in a flat vulcanizer for heating and pressurization to mature the raw rubber and integrate it with the steel wire rope. The rubber with the steel wire rope is then subjected to a tensile test. The process can be put into mass production only when the test results meet the corresponding standards.

[0003] However, since the raw rubber added to the mold is in block form, when the raw rubber is added to the mold, the raw rubber will support the mold, making the upper and lower molds non-parallel. At this time, during the pressurization process of the flat vulcanizer, the upper and lower molds will be misaligned, causing the molds to gnaw at each other, thereby causing damage to the mold, and even damaging the mold, and affecting the subsequent use of the mold.

[0004] Therefore, how to provide a wire rope conveyor belt die detection device that can prevent the die dies from biting each other and protect the die is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of this, the present invention provides a wire rope conveyor belt die detection device, which aims to solve the problem of upper die and lower die biting each other in the prior art and overcome the damage to the die during the die pressing process.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A die detection device for a steel wire rope conveyor belt, comprising: an upper die, a lower die and a guiding part. A plurality of mounting holes and a plurality of positioning holes are provided on the lower surface of the upper die and the upper surface of the lower die. The mounting holes on the upper die correspond to the positioning holes on the lower die, and the positioning holes on the upper die correspond to the mounting holes on the lower die. The guiding part includes a telescopic guiding member and a guiding assembly. Each of the mounting holes on the upper die and the lower die is provided with the telescopic guiding member. The telescopic guiding member includes a positioning pin, a limiting sleeve and a spring. The limiting sleeve is embedded in one end of the mounting hole close to the opening. One end of the positioning pin is clamped with one end of the spring located in the mounting hole close to the limiting sleeve. The other end of the positioning pin penetrates through the limiting sleeve and extends outside the mounting hole to cooperate with the corresponding positioning hole. The guiding assembly includes a guiding block and a guiding groove. The guiding groove is formed by splicing two fixing plates on the side wall of the lower die. The guiding block is fixed on the side wall of the upper die, and the guiding block is adapted to the guiding groove.

[0008] Further, the die detection device for the steel wire rope conveyor belt further includes a detachable sleeve. The detachable sleeve is embedded in the positioning hole, and the part of the positioning pin extending outside the mounting hole is adapted to the corresponding detachable sleeve.

[0009] Furthermore, the positioning pin includes a clamping section, a protruding section and an inserting section. The clamping section, the protruding section and the inserting section are connected in sequence and integrally formed. The inserting section penetrates through the limiting sleeve and extends outside the mounting hole. The inserting section is adapted to the detachable sleeve, and the protruding section is adapted to the inner wall of the mounting hole.

[0010] Further, the guiding assembly further includes a first backing plate and a second backing plate. The first backing plate and the second backing plate have the same thickness. The first backing plate is detachably connected to the side wall of the upper die. The guiding block is detachably connected to the first backing plate. The second backing plate is detachably connected to the side wall of the lower die. The two fixing plates are detachably connected to the second backing plate.

[0011] Further, the upper surface of the lower die has a first die cavity, a protruding part and a first groove. There are two protruding parts, and the two protruding parts are symmetrically arranged on both sides of the first die cavity. The first groove extends from the protruding part on one side of the first die cavity to the protruding part on the opposite side. The upper die is provided with a recess adapted to the protruding part, a second die cavity corresponding to the first die cavity, and a second groove corresponding to the first groove. The first groove and the second groove cooperate to form a receiving cavity for receiving the steel wire rope.

[0012] Furthermore, there are a plurality of the first die cavities and the second die cavities. The plurality of first die cavities and the plurality of second die cavities are arranged at intervals and correspond to each other one by one.

[0013] Further, a plurality of the first grooves and a plurality of the second grooves are provided. The plurality of the first grooves are arranged at intervals along the length direction of the convex portion, and the plurality of the second grooves are arranged at intervals along the length direction of the concave portion. The plurality of the second grooves correspond to the plurality of the first grooves one by one.

[0014] Further, a handheld portion is provided on both the upper mold and the lower mold.

[0015] As can be seen from the above technical solutions, compared with the prior art, the present invention discloses a die detection device for a steel wire rope conveyor belt. By means of the telescopic guiding members provided on the upper mold and the lower mold, a block-shaped raw rubber to be cured can be assembled in the mold. The block-shaped raw rubber supports the upper mold. At this time, the upper mold and the lower mold are in a non-parallel state. The positioning pins extend into the corresponding positioning holes. During the initial compression process of the flat vulcanizing machine, the telescopic guiding members first perform guiding and positioning, thereby being able to solve the problem of mutual gnawing between the upper mold and the lower mold when they are in a non-parallel state. When the flat vulcanizing machine further compresses to make the upper mold and the lower mold parallel, the guiding components on the side walls of the mold start to function, and the guiding blocks extend into the guiding grooves for guiding. During the later compression process of the flat vulcanizing machine, the positioning pins and the guiding blocks jointly act to guide the movement between the upper mold and the lower mold. At the same time, a part of the positioning pins is compressed into the mounting holes, thereby realizing the protection of the mold and preventing damage to the mold caused by mutual gnawing.
