Description

Technical Field

[0001] The utility model relates to the technical field of insulating board processing, in particular to an insulating board testing press. Background Art

[0002] Due to the problem of process level or operation, the plate with serious warping needs to be re-pressed to eliminate stress for subsequent flattening. When hot pressing and flattening the warped plate, the pressure and heating temperature need to be controlled.

[0003] In the prior art, there is an insulating board leveling device with publication number: CN220742115U, which includes a base, a bearing plate is provided at the center of the upper end surface of the base, first movable grooves are provided on both sides of the upper end surface of the base, and leveling components are provided in the two first movable grooves, and a clamping component is provided on the bearing plate; the leveling component includes a first motor installed in the two movable grooves, the output ends of the two first motors are connected to a first threaded rod, and the ends of the two first threaded rods away from the first motor are provided with a first bearing, ... The end of the limit rod extending out of the second cavity is fixedly connected to a clamping plate, and a buffer spring is sleeved on the limit rod. When the device is in use, it can only level one insulating board, and the efficiency is low. At the same time, it lacks a heating function, and the leveling effect is not good.

[0004] For another example, the experimental press for a polyester fiber insulation board with the publication number CN203766054U comprises a frame, a hydraulic cylinder, an upper support plate, an upper high-temperature resistant buffer pad, an upper heating plate, an upper hot pressing panel, a lower support plate, a lower high-temperature resistant buffer pad, a lower heating plate, a lower hot pressing panel, a pressure gauge and a control panel; the hydraulic cylinder is fixedly mounted on the frame, the lower support plate is mounted on the movable rod of the hydraulic cylinder, and the lower high-temperature resistant buffer pad is mounted on the lower support plate, the lower heating plate is mounted on the lower high-temperature resistant buffer pad, and the lower hot pressing panel is mounted on the lower heating plate; the upper support plate is fixedly mounted on the frame, opposite to the lower support plate, and the upper high-temperature resistant buffer pad is mounted on the upper support plate, the upper heating plate is mounted on the upper high-temperature resistant buffer pad, the upper hot pressing panel is mounted on the upper heating plate, and the upper hot pressing panel is opposite to the lower hot pressing panel; a pressure gauge for detecting the pressure generated by the hydraulic cylinder is mounted on the frame, and a control panel is mounted on one side of the frame to control the pressure of the hydraulic cylinder and the temperature of the upper heating plate and the lower heating plate. The equipment can perform secondary processing on warped plates to achieve flattening of the plates, but when in use, it can only perform secondary processing and flattening on one insulating board. At the same time, it is also relatively inaccurate to infer the pressure between the hot pressing panels by detecting the pressure generated by the hydraulic cylinder through a pressure gauge.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-2 As shown, the insulating board test press of this embodiment includes a box body 1, and a plurality of lifting plates 2 are arranged longitudinally and equidistantly above the inner cavity of the box body 1. The plurality of lifting plates 2 can hot press a plurality of insulating boards. A hot pressing plate 3 and a hot pressing groove 4 are arranged on one side of the lifting plates 2 close to each other. A guide rod 5 is fixedly installed in the box body 1. The lifting plates 2 penetrate the guide rod 5 and are slidably connected with the guide rod 5. The outer wall of the guide rod 5 is provided with a spring 6 between adjacent lifting plates 2. The spring 6 can allow a spacing between the lifting plates 2, which is convenient for placing or removing the insulating board. A hydraulic cylinder 7 is fixedly installed at the bottom position of the inner cavity of the box body 1. One end of the top of the hydraulic cylinder 7 is fixedly connected to the lifting plate 2 at the bottom layer. A fixed rod 8 is fixedly installed at the top position of the inner cavity of the box body 1. A pressure sensor 9 is fixedly installed at the bottom position of the fixed rod 8. The pressure sensor 9 can detect the pressure. A hot oil heating mechanism 10 for heating the lifting plates 2 is also installed on the box body 1. The hot oil heating mechanism 10 is used to heat the inner cavity of the hot pressing groove 4 and the hot pressing plate 3.

[0023] Furthermore, the hot oil heating mechanism 10 includes a liquid inlet pipe 1001 , a liquid return pipe 002 , an oil tank 1003 and a circulating pump 1004 , an oil channel is provided in the hot pressing plate 3 , and a heating rod is provided in the oil tank 1003 .

[0024] Furthermore, a thermometer 11 is provided on the liquid inlet pipe (001) for detecting the temperature of the hot oil in the oil tank 1003.

[0025] Furthermore, a switch door 12 is installed on one side of the front of the box body 1.

[0026] Working principle: The individual insulating boards to be leveled are placed in the hot pressing tank 4 respectively. The hot oil heating mechanism 10 is used to heat the inner cavity of the hot pressing tank 4 and the hot pressing plate 3, and the plates inside the hot pressing tank 4 are heated. When the hydraulic cylinder 7 drives the lifting plate 2 to rise, the distance between the adjacent lifting plates 2 becomes smaller, and the hot pressing plate 3 re-presses the plates inside the hot pressing tank 4 to eliminate stress. The pressure sensor 9 can obtain the pressure of the top lifting plate 2 on the pressure sensor 9, and obtain the pressure of the hot pressing plate 3 on the hot pressing tank 4 (the elastic force of the spring 6 is relatively small and can be ignored). After a certain period of hot pressing, the hydraulic cylinder 7 is reset, and the re-hot pressed plates can be taken out.
