Description

Technical Field

[0001] The invention belongs to the technical field of rubber processing, and in particular relates to a wear-resistant rubber lining pressure molding device. Background Art

[0002] Wear-resistant rubber lining is a kind of equipment protection material made of high-quality rubber. It has high wear resistance, impact resistance and corrosion resistance. It is installed inside various equipment to effectively reduce equipment wear, extend equipment service life and reduce maintenance costs. Wear-resistant rubber lining needs to go through the steps of mixing, rubber mixing, pressure molding and vulcanization treatment during the production process. Pressure molding equipment is also required in the pressure molding process, such as the patent authorization announcement number CN115027025B, a wear-resistant rubber lining molding equipment.

[0003] At present, in the pressure forming process of wear-resistant rubber lining, the kneaded blank needs to be placed in the forming mold. In order to ensure complete forming, the blank fed into the mold is mostly excessive. After forming, the excess scraps need to be manually cut off and recycled. However, this processing method is cumbersome and inconvenient, affecting the efficiency and convenience of pressure forming. At the same time, the rubber scraps need to be crushed and re-kneaded after recycling, which can easily cause changes in the molecular structure of rubber, resulting in a decrease in the strength and elasticity of the rubber, which in turn affects the quality of subsequent wear-resistant rubber linings.

[0004] In addition, after the wear-resistant rubber lining is extruded in the molding die, it takes time to wait for cooling to increase the hardness of the wear-resistant rubber and ensure that the lining will not be damaged when the staff takes it out. However, this waiting for cooling process further affects the efficiency and convenience of the wear-resistant rubber lining pressure molding process.

[0016] Compared with the existing technology, the advantages of a wear-resistant rubber lining pressure forming equipment are:

[0017] Through the pressure forming mechanism, hollow bottom plate and forming mold frame, when the wear-resistant rubber lining is produced, the kneaded wear-resistant rubber lining blank is first quantitatively squeezed into the center of the forming mold frame just below the adjustment cover through the conveying equipment, and the wear-resistant rubber lining blank is supported by the upper surface of the hollow bottom plate. At this time, the PLC controller controls the pressure forming mechanism to work. After each retraction of the electric hydraulic rod in the pressure forming mechanism, the PLC controller controls the servo motor to drive the forming mold frame to rotate 60 degrees, so that the wear-resistant rubber lining blank is sequentially subjected to the pre-extrusion treatment, extrusion treatment and other treatments of the adjusting cover.

[0018] Through the set temperature regulating mechanism, the wear-resistant rubber lining pressure molding equipment controls the temperature regulating mechanism to work while molding the wear-resistant rubber lining, and generates hot air and low-temperature air. The hot air is transported to the ventilation cavity of the hollow bottom plate and the adjustment cover, and finally the hot air can be blown to the periphery of the wear-resistant rubber lining blank to avoid the surface temperature of the wear-resistant rubber lining blank from lowering and hardening, and to ensure the elongation of the wear-resistant rubber lining blank, thereby ensuring that the wear-resistant rubber lining blank can fully fill the molding mold frame during extrusion molding, thereby ensuring the quality of the wear-resistant rubber lining molding process. This mechanism enables the wear-resistant rubber lining pressure molding equipment to have the function of heat preservation of the wear-resistant rubber lining blank, avoids the occurrence of stratification defects during the molding of the wear-resistant rubber lining, and can improve the quality of the wear-resistant rubber lining molding process.

[0019] By means of the set temperature regulating mechanism and air guide assembly, when the formed wear-resistant rubber lining is transported by the forming mold frame to the cooling plate on the upper surface of the hollow bottom plate for cooling, the low-temperature air generated by the temperature regulating mechanism is transported to the cooling plate and the hollow block respectively through the first air pipe and the second air pipe, the low-temperature cooling plate cools the bottom of the wear-resistant rubber lining, and the low-temperature air sprayed by the hollow block cools the top of the formed wear-resistant rubber lining, and the hardness of the wear-resistant rubber lining is improved by cooling, and then the suspended wear-resistant rubber lining rotated out of the forming mold frame is automatically demoulded under the action of its own gravity and the airflow sprayed by the demoulding air pipe, which saves time and effort. The mechanism enables the wear-resistant rubber lining pressure molding equipment to have the functions of automatic demoulding of the wear-resistant rubber lining and rapid cooling to increase the hardness of the rubber, and can improve the convenience and efficiency of the wear-resistant rubber lining molding process.

[0033] The outer wall of the heat insulation box 72 located in the cooling zone 77 is fixedly connected to an air guide component 9, and the air guide component 9 includes a first air pipe 91 and a second air pipe 92. The air inlet ends of the first air pipe 91 and the second air pipe 92 are fixedly connected to the outer wall of the cooling zone 77 of the heat insulation box 72, the top end of the first air pipe 91 is fixedly connected to the outer wall of the cooling zone 14 of the hollow bottom plate 1, the top end of the second air pipe 92 is fixedly connected to a hollow block 93, the lower surface of the hollow block 93 is provided with a mounting hole, and the hole wall of the mounting hole is fixedly connected to a porous air permeable plate 94, and the outer wall of the hollow bottom plate 1 located in the cooling zone 14 is fixedly connected to a demolding air pipe 95.

[0034] The electric hydraulic rod 61, the electric heating tube 82, the servo motor 11, the one-way air pump 18 and the normally closed solenoid valve 19 are all electrically connected to the input end of the PLC controller 710 through wires, and the temperature sensor 79 is electrically connected to the input end of the PLC controller 710 through wires. These powered devices and electrical connections are all existing technologies and will not be repeated here.

[0035] The operating principle of the present invention is described as follows: when the wear-resistant rubber lining is produced, the kneaded wear-resistant rubber lining blank is first quantitatively squeezed into the center of the forming mold frame 5 just below the adjustment cover 64 through the conveying equipment, and the wear-resistant rubber lining blank is supported by the upper surface of the hollow bottom plate 1. At this time, the PLC controller 710 controls the pressure forming mechanism 6 to work. While the pressure forming mechanism 6 is working, the cooling zone 14 of the hollow bottom plate 1 is also cooled by the temperature adjustment mechanism 7 to speed up the molding efficiency of the wear-resistant rubber lining. Specifically, the PLC controller 710 controls the electric hydraulic The movable end of the rod 61 extends, and the movable end of the electric hydraulic rod 61 pushes the adjustment cover 64 and the extrusion template 63 downward through the connecting frame 62. After the adjustment cover 64 moves downward, the wear-resistant rubber lining blank located below the adjustment cover 64 can be pre-extruded. During the pre-extrusion process of the wear-resistant rubber lining blank, the irregular wear-resistant rubber lining blank is squeezed by the adjustment cover 64 to become a wear-resistant rubber lining semi-finished product. Because the adjustment cover 64 is directly above the center of the forming mold frame 5, the wear-resistant rubber lining semi-finished product is located at the center of the forming mold frame 5. At this time, the four side walls of the wear-resistant rubber lining semi-finished product are aligned with the inner wall of the forming mold frame 5. There is a filling space reserved in between, and the distances between the four side walls of the semi-finished product and the inner wall of the forming mold frame 5 are the same, so that the wear-resistant rubber lining semi-finished product can be evenly filled with the reserved filling space when it is extruded by the extrusion template 63. Specifically, in the initial stage of the final pressure forming of the wear-resistant rubber lining semi-finished product in the forming mold frame 5 when the extrusion template 63 moves downward, the blank at the top of the wear-resistant rubber lining semi-finished product is forced to move downward, and the blank at the bottom of the wear-resistant rubber lining semi-finished product is spread toward the inner wall of the forming mold frame 5 under the action of pressure due to the strong extensibility of the rubber blank. As the extrusion template 63 moves downward, the rubber blank has a strong extensibility and spreads toward the inner wall of the forming mold frame 5. As the pressure of the wear-resistant rubber lining increases, the blank at the bottom of the semi-finished product of the wear-resistant rubber lining is continuously subjected to the extrusion force and will gradually fill the reserved filling space. When the extrusion template 63 contacts the top of the molding die frame 5, the blank at the top of the semi-finished product of the wear-resistant rubber lining will be replaced to the position of the original blank at the bottom of the semi-finished product. At the same time, the blank at the original bottom of the semi-finished product of the wear-resistant rubber lining will extend outwards to fully fill the reserved filling space, thereby completing the pressure molding of the wear-resistant rubber lining. In addition, due to the constraints of the molding die frame 5 and the extrusion template 63, it is possible to prevent the rubber blank of the wear-resistant rubber lining from overflowing the molding die frame 5 and generating scrap waste.

[0036] After the adjusting cover 64 is squeezed into place, the PLC controller 710 controls the electric hydraulic rod 61 to retract. After the moving end of the electric hydraulic rod 61 is retracted, the PLC controller 710 then controls the output end of the servo motor 11 to rotate 60 degrees. The servo motor 11 drives the forming mold frame 5 to rotate 60 degrees through the rotating block 4. The process of the forming mold frame 5 rotating 60 degrees will drive the pre-extruded wear-resistant rubber lining blank to be transported to the bottom of the extrusion template 63. The next forming mold frame 5 is simultaneously transported to the bottom of the adjusting cover 64, and it is convenient for the next wear-resistant rubber lining blank to fall into the forming mold frame 5 located under the adjusting cover 64. This cycle ensures the processing speed of the wear-resistant rubber lining. After the output end of the servo motor 11 rotates 60 degrees, the PLC controller 710 controls the moving end of the electric hydraulic rod 61 to move downward. The electric hydraulic rod 61 pushes the adjusting cover 64 and the extrusion template 63 downward again through the connecting frame 62. The adjusting cover 64 repeats the above steps to pre-extrude the wear-resistant rubber lining blank, and the extrusion template 63 can The wear-resistant rubber lining blank is then extruded and formed, wherein the materials of the hollow bottom plate 1, the forming mold frame 5, the extrusion template 63, the adjustment cover 64 and the cooling plate 15 are all silicon carbide ceramics, and the silicon carbide ceramics have high hardness and strength due to the compact crystal structure and strong interatomic bonding force, and the special electronic and crystal structure inside the silicon carbide makes it have good thermal conductivity, and the silicon carbide ceramics also have the characteristics of smooth surface, stable chemical properties and low surface energy, so that the silicon carbide ceramics and the high-temperature soft rubber are not easy to adhere to each other due to the lack of adhesion and mechanical interlocking force after contact, avoiding the high-temperature wear-resistant rubber lining blank from adhesion and unable to be formed normally. At the same time, the pre-extruded wear-resistant rubber lining blank can be fully and evenly dispersed under the constraints of the forming mold frame 5, the hollow bottom plate 1 and the extrusion template 63, and there will be no excess wear-resistant rubber lining raw materials overflowing into scraps, so there is no need to manually trim the scraps of the wear-resistant rubber lining, and there is no need to recycle the scraps for reuse, and there will be no situation where the quality of the wear-resistant rubber lining is reduced due to the recycling of the recycled rubber;

[0037] After the extrusion template 63 is extruded into place, the PLC controller 710 controls the moving end of the electric hydraulic rod 61 to retract. At the same time, the PLC controller 710 controls the output end of the servo motor 11 to rotate 60 degrees. After the output end of the servo motor 11 drives the forming mold frame 5 to rotate 60 degrees, the forming mold frame 5 can transfer the pressure-formed wear-resistant rubber lining to the cooling plate 15, and further blow low-temperature air through the temperature regulating mechanism 7 to cool the formed wear-resistant rubber lining, and can improve the hardness of the wear-resistant rubber lining. This mechanism enables the wear-resistant rubber lining pressure forming equipment to have the functions of pre-extrusion and high-precision pressure forming of wear-resistant rubber lining blanks, and also has the function of quickly cooling the wear-resistant rubber lining to improve the hardness of rubber, avoiding the generation of scraps during the forming process of the wear-resistant rubber lining, which can effectively reduce the labor intensity of the staff, and can effectively improve the efficiency and convenience of the wear-resistant rubber lining forming process.

[0038] While the wear-resistant rubber lining is being formed by pressure, the PLC controller 710 also controls the one-way air pump 18 to start, and the one-way air pump 18 inflates the air storage box 17 for 1 minute to increase the air pressure in the air storage box 17. Then the PLC controller 710 controls the normally closed solenoid valve 19 to be energized and opened, and the high-pressure air in the air storage box 17 is transported to the air inlet area 75 of the heat insulation box 72 through the conduit 71, and then the high-pressure air enters the vortex tube 74, and the high-pressure air rotates at a high speed in the vortex tube 74, and forms a high-speed vortex in the tube. At the same time, due to the action of centrifugal force, the air The vortex tube 74 is radially divided into an inner and outer part. The inner and outer airflows will produce friction due to the different angular velocities, and there is a pressure gradient in the vortex tube 74, which eventually reduces the pressure of the inner and outer airflows in the vortex tube 74, and the temperature drops rapidly to become low-temperature air. The pressure of the inner airflow increases, and the temperature increases to become hot air. In this way, hot air and low-temperature air are generated at both ends of the vortex tube 74, respectively. The temperature of the hot air is in the range of 45-56 degrees Celsius, and the temperature of the low-temperature air is in the range of 2-10 degrees Celsius. The low-temperature air passes through the first air pipe 91 and the second air pipe 92. The two air pipes 92 are transported to the cooling zone 14 of the hollow bottom plate 1 and the hollow block 93. The low-temperature air in the cooling zone 14 of the hollow bottom plate 1 reduces the surface temperature of the cooling plate 15. The low-temperature cooling plate 15 can easily cool the bottom of the wear-resistant rubber lining and increase the hardness of the wear-resistant rubber lining. The cold air sprayed from the porous air permeable plate 94 of the hollow block 93 flows to the top of the wear-resistant rubber lining, further accelerating the cooling of the wear-resistant rubber lining. Moreover, since the porous air permeable plate 94 is far away from the top of the wear-resistant rubber lining, the cold air can be sprayed to the top of the wear-resistant rubber lining more evenly. The wear-resistant rubber lining is ensured to be cooled uniformly on the top of the wear-resistant rubber lining, and the wear-resistant rubber lining is accelerated to cool and harden. The cooled wear-resistant rubber lining is transferred to the demoulding area outside the hollow bottom plate 1 by the forming mold frame 5. At the same time, the cold air in the cooling area 14 of the hollow bottom plate 1 is discharged through the demoulding air pipe 95. The demoulding air pipe 95 guides the airflow to the top of the demoulding area. Then, the wear-resistant rubber lining formed in the forming mold frame 5 is directly dropped from the suspended forming mold frame 5 by the gravity and the thrust of the airflow ejected by the demoulding air pipe 95, so that the wear-resistant rubber lining is automatically demoulded, saving time and effort.

[0039] The hot air is input into the insulation area 13 of the hollow bottom plate 1 through the air inlet pipe 78 of the insulation box 72. At the same time, the temperature sensor 79 monitors the temperature of the hot air. The temperature sensor 79 transmits the detection result to the PLC controller 710 in the form of an electrical signal. When the detected hot air temperature does not reach the temperature threshold preset by the PLC controller 710, the PLC controller 710 controls the electric heating tube 82 to work. The electric heating tube 82 generates heat to increase the temperature of the hot air through the heat-conducting mesh plate 81, so that the temperature of the hot air reaches 160 degrees Celsius. At this time, the PLC controller 710 controls the heating power of the electric heating tube 82 according to the temperature signal detected by the temperature sensor 79, and ensures that the temperature of the hot air is always maintained at 160 degrees Celsius. In addition, the hot air at 160 degrees Celsius is connected to the hose 6 7 is transported to the ventilation cavity 65 and the ventilation hole 66 of the adjustment cover 64, so that the hot air can be distributed around the wear-resistant rubber lining blank, and then the surface of the wear-resistant rubber lining blank hardens due to cooling, the soft wear-resistant rubber lining blank has extensibility, and can fully fill the molding cavity, and the surface of the wear-resistant rubber lining blank maintained at a relatively high temperature will not cause the outer wall of the wear-resistant rubber lining to produce stratification defects due to hardening, which can ensure the quality of the wear-resistant rubber lining. This mechanism enables the wear-resistant rubber lining pressure molding equipment to have the functions of heat preservation of the wear-resistant rubber lining blank and automatic demolding of the wear-resistant rubber lining, avoiding stratification defects during the molding of the wear-resistant rubber lining, which can not only improve the quality of the wear-resistant rubber lining molding process, but also improve the convenience and efficiency of the wear-resistant rubber lining molding process.
