Description

Technical Field

[0001] The utility model relates to the technical field of V-belt production equipment, in particular to a pressurizing device of a V-belt vulcanizing machine. Background Art

[0002] V-belt refers to a transmission belt with an isosceles trapezoid or an approximately isosceles trapezoidal cross section. Vulcanization is one of the main processes in the processing of rubber V-belts that directly affects the performance and life of the product. The existing V-belt production process generally includes a vulcanization process. There are three main existing vulcanization processes: flat plate vulcanization, round die vulcanization, and drum vulcanization. Among them, round die vulcanization has the advantages of uniformity, beauty, and high efficiency. Round die vulcanization is to put the already prepared V-belt on the mold in sequence, then put on the rubber sleeve, hang it into the vulcanization tank, cover the cover plate, close the tank cover, and vulcanize and compress it. In the process of putting the V-belt on the mold in sequence, after the V-belt is molded in the round mold, it is necessary to pressurize the round mold, tighten the fastening screws and fix the round mold. However, there is no special vulcanization mold pressurization device in the V-belt production process, and it is difficult to effectively pressurize the vulcanization mold, which not only reduces the mold efficiency of the V-belt, but also makes the mold pressurization pressure uneven, affecting the subsequent vulcanization effect of the V-belt. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a pressurizing device for a V-belt vulcanizer.

[0004] The purpose of the utility model is achieved through the following technical scheme: it includes a support frame, on which a hydraulic cylinder and a template assembly are arranged, an articulated seat is fixedly arranged at the output end of the hydraulic cylinder, the articulated seat and the template assembly are transmission-connected via a pressure rod assembly, scissor-type mechanisms are arranged on both sides of the template assembly, and the pressure rod assembly is hinged to the support frame.

[0005] Preferably, the pressure rod assembly includes a push rod, an upper push rod and a lower push rod, the upper end of the upper push rod is hinged to the support frame, the lower end of the lower push rod is hinged to the template assembly, the lower end of the upper push rod is hinged to the upper end of the lower push rod, one end of the push rod is hinged to the hinge seat, and the other end is hinged to the connecting position of the upper push rod and the lower push rod.

[0006] Preferably, the template assembly includes an upper template, a middle template and a lower template, the upper template is hinged to one end of the lower push rod away from the push rod, the upper template, the middle template and the lower template are connected by a scissors-type mechanism, and the upper template, the middle template and the lower template are hinged to the upper end, the middle part and the lower end of the scissors-type mechanism respectively.

[0008] Preferably, two ends of the first connecting rod group are respectively hinged to the upper template and the lower template, and two ends of the second connecting rod group are respectively hinged to the upper template and the lower template through an upper hinge block and a lower hinge block.

[0009] Preferably, the hinge seat is arranged in a cross shape.

[0010] Preferably, a limiting rod is provided on the support frame, and the upper template and the middle template are both slidably arranged on the limiting rod.

[0011] The utility model has the following advantages:

[0012] 1. When the upper template, the middle template and the lower template are in contact, the output end of the hydraulic cylinder continues to press down, pushing the push rod to rotate and move downward relative to the hinge seat, and the push rod pushes the hinge point between the upper ejector rod and the lower ejector rod to move away from the hinge seat. When the push rod rotates to a horizontal state, the upper ejector rod and the lower ejector rod rotate to a vertical state at the same time, and the upper ejector rod and the lower ejector rod form a self-locking state to ensure the tightness and stability between the upper template, the middle template and the lower template. In this process, the template assembly is pressurized.

[0013] 2. The cross-shaped hinge seat applies uniform force to the upper template through multiple pressure rod assemblies, and the force application position is close to the edge of the upper template, thereby ensuring that the template assembly is evenly pressurized.

[0014] 2. By setting up a scissor-type mechanism, when the V-belt needs to be installed, all the V-belts can be placed on the template assembly for mold loading and pressurization at the same time, thereby improving the mold loading efficiency of the V-belt; when the V-belt needs to be removed, the upper template, the middle template and the lower template can be opened at the same time, and the staff can remove the V-belt, thereby improving work efficiency.

[0022] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0023] like Figures 1 to 3As shown, a pressurizing device of a V-belt vulcanizer comprises a support frame 1, on which a hydraulic cylinder 2 and a template assembly 3 are arranged, an articulated seat 21 is fixedly arranged at the output end of the hydraulic cylinder 2, the articulated seat 21 and the template assembly 3 are connected by a pressurizing rod assembly, scissor-type mechanisms 34 are arranged on both sides of the template assembly 3, and the pressurizing rod assembly is hinged to the support frame 1. The lower surface of the upper template 31, the upper and lower surfaces of the middle template 32 and the upper surface of the lower template 33 are provided with grooves for placing the V-belt. The prepared V-belt is placed in the grooves on the upper surfaces of the middle template 32 and the lower template 33 respectively. Then the hydraulic cylinder 2 is started, and the hydraulic cylinder 2 pushes the push rod 22 downward through the hinge seat 21. The push rod 22 pushes the lower push rod 24 downward, and the lower push rod 24 pushes the upper template 31 and the middle template 32 to move downward at the same time. At the same time, the angle between the upper push rod 23 and the lower push rod 24 increases, and the push rod 22 gradually tends to horizontal from vertical until the upper template 31, the middle template 32 and the lower template 33 are in contact at the same time to complete the V-belt molding. At this time, it is necessary to pressurize the template assembly 3, and the output end of the hydraulic cylinder 2 continues to press downward. The hinge seat 21 pushes the push rod 22 to rotate to a horizontal state, and at the same time, the upper push rod 23 and the lower push rod 24 rotate to a vertical state to form a self-locking state, thereby ensuring the stability between the upper template 31, the middle template 32 and the lower template 33.

[0024] Furthermore, the pressure rod assembly includes a push rod 22, an upper push rod 23 and a lower push rod 24, the upper end of the upper push rod 23 is hinged to the support frame 1, the lower end of the lower push rod 24 is hinged to the template assembly 3, the lower end of the upper push rod 23 is hinged to the upper end of the lower push rod 24, one end of the push rod 22 is hinged to the hinge seat 21, and the other end is hinged to the connection position of the upper push rod 23 and the lower push rod 24. In this embodiment, the upper end of the upper push rod 23 is hingedly set on the support frame 1. During the downward movement of the push rod 22, the upper push rod 23 is pushed to rotate with the hinge point between the upper push rod 23 and the support frame 1 as a fulcrum, and the lower push rod 24 is pushed to move downward and rotate relative to the upper template 31, thereby pushing the upper template 31 downward. When the upper template 31, the middle template 32 and the lower template 33 are in contact at the same time, the output end of the hydraulic cylinder 2 continues to press downward, pushing the push rod 22 to rotate and move downward relative to the hinge seat 21, and the push rod 22 pushes the hinge point between the upper push rod 23 and the lower push rod 24 to move away from the hinge seat 21. When the push rod 22 rotates to a horizontal state, the upper push rod 23 and the lower push rod 24 rotate to a vertical state at the same time. In this process, the pressurization of the template assembly 3 is completed.

[0025] Further, the template assembly 3 includes an upper template 31, a middle template 32 and a lower template 33, the upper template 31 is hinged to one end of the lower push rod 24 away from the push rod 22, the upper template 31, the middle template 32 and the lower template 33 are connected by a scissor-type mechanism 34, and the upper template 31, the middle template 32 and the lower template 33 are respectively hinged to the upper end, the middle part and the lower end of the scissor-type mechanism 34. In this embodiment, the spacing between the upper template 31 and the middle template 32 is the same as the spacing between the middle template 32 and the lower template 33. The scissor-type mechanism 34 is used to achieve that when the upper template 31 moves downward, the middle template 32 moves downward at half the speed of the upper template 31, so that the upper template 31, the middle template 32 and the lower template 33 can finally contact at the same time. By setting up the scissor-type mechanism 34, when the V-belt needs to be installed, all the V-belts can be placed on the template assembly 3 for mold loading and pressurization at the same time, thereby improving the mold loading efficiency of the V-belt; when the V-belt needs to be removed, the upper template 31, the middle template 32 and the lower template 33 can be opened at the same time, and the V-belt can be removed by the staff, thereby improving work efficiency.

[0026] Further, the scissor-type mechanism 34 includes a first connecting rod group 341 and a second connecting rod group 342, and the middle parts of the first connecting rod group 341 and the second connecting rod group 342 are both hinged to the middle template 32. In this embodiment, the first connecting rod group 341 and the second connecting rod group 342 are both composed of two short rods and a long rod, one end of the two short rods is respectively hinged to the two ends of the long rod, and the other end is respectively hinged to the upper template 31 and the lower template 33, and the middle part of the long rod is hinged to the middle template 32.

[0027] Furthermore, the two ends of the first connecting rod group 341 are respectively hinged to the upper template 31 and the lower template 33, and the two ends of the second connecting rod group 342 are respectively hinged to the upper template 31 and the lower template 33 through the upper hinge block 311 and the lower hinge block 331.

[0028] Furthermore, the articulated seat 21 is configured in a cross shape. In this embodiment, each protruding leg of the cross-shaped articulated seat 21 is hinged to the pressure rod assembly as a hinge point, so that when the articulated seat 21 descends, a plurality of pressure rod assemblies can be used to evenly apply force to the upper template 31, and the force application position is close to the edge of the upper template 31, thereby ensuring that the template assembly 3 is evenly pressed.

[0029] Furthermore, a limiting rod 11 is provided on the support frame 1, and the upper mold plate 31 and the middle mold plate 32 are both slidably provided on the limiting rod 11. In this embodiment, the limiting rod 11 is used to limit the movement track of the upper mold plate 31 and the middle mold plate 32, so as to ensure that the upper mold plate 31, the middle mold plate 32 and the lower mold plate will not deviate or tilt, thereby ensuring the quality of the V-belt vulcanization.

[0030] When implementing:

[0031] The V-belt that has been made is placed in the grooves on the upper surfaces of the middle template 32 and the lower template 33 respectively, and then the hydraulic cylinder 2 is started. The hydraulic cylinder 2 pushes the push rod 22 downward through the hinge seat 21. During the downward movement of the push rod 22, the upper push rod 23 is rotated by using the hinge point between the upper push rod 23 and the support frame 1 as a fulcrum, and the lower push rod 24 is pushed downward and rotated relative to the upper template 31, thereby pushing the upper template 31 and the middle template 32 to move downward at the same time. At the same time, the angle between the upper push rod 23 and the lower push rod 24 increases, and the push rod 22 gradually tends to be horizontal from vertical , until the upper template 31, the middle template 32 and the lower template 33 are in contact at the same time, the output end of the hydraulic cylinder 2 continues to press down, pushing the push rod 22 to rotate and move downward relative to the hinge seat 21, and the push rod 22 pushes the hinge point between the upper push rod 23 and the lower push rod 24 to move away from the hinge seat 21. When the push rod 22 rotates to a horizontal state, the upper push rod 23 and the lower push rod 24 rotate to a vertical state at the same time, forming a self-locking state, ensuring the stability between the upper template 31, the middle template 32 and the lower template 33, and completing the pressurization of the template assembly 3 in this process.
