Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fire fighting equipment, in particular to a fire detection tube self-sealing processing device. BACKGROUND

[0002] The fire detection tube is a new type of fire extinguishing device, which has the characteristics of simple structure and high reliability. It can not only automatically detect and extinguish fire, but also does not need power supply and traditional fire alarm control components, greatly improving the reliability of the fire extinguishing device.

[0003] At present, the common sealing method of the fire detection tube is to connect a pipe plug at the end of the pipeline. The pipe plug and the fire detection tube are connected through screwing. The metal nut extrudes the plastic pipe material and deforms to tightly attach the metal pipe joint, thereby achieving the sealing effect. In some specific occasions, such as the fire detection tube fire extinguishing system applied in new energy battery packs, the sealing method of the pipe plug needs to consider the design of the fixing structure of the pipe plug, which has a complex structure and safety hazards. Therefore, a self-sealing method is developed to seal the fire detection tube, and a processing device is developed for this sealing method. SUMMARY

[0004] In view of the problems in the prior art, the utility model provides a fire detection tube self-sealing processing device which is easy to operate, has high production efficiency and good sealing processing effect.

The hot pressing upper die and the hot pressing lower die are respectively provided with upper and lower pressing grooves. The upper and lower pressing grooves are respectively provided with protrusions that are misaligned.

[0006] Based on the above, when the fire detection tube is processed, the fire detection tube is placed on the lower pressing groove. Then the hot pressing upper die and the hot pressing lower die cooperate to heat and soften the fire detection tube, and press the fire detection tube. When pressing, the protrusions on the hot pressing upper die and the hot pressing lower die are misaligned, which improves the sealing performance of the fire detection tube. The overall structure of the processing device is simple and easy to operate. The auxiliary limiting is achieved by the detachable limiting block, which improves the processing efficiency and ensures the self-sealing effect of the fire detection tube.

[0007] Further, the rack comprises a base, a support rod and a cylinder mounting plate. The driving device is fixedly installed on the cylinder mounting plate.

[0008] Further, one end of the lower pressing groove is fixedly matched with a detachable limiting block, and one end of the upper pressing groove is provided with a avoiding groove matched with the detachable limiting block.

[0009] Based on the above, when sealing processing is performed, the detachable limiting block is quickly and auxiliary limited, the processing efficiency is improved, meanwhile, each product can be processed to the same area, and the overall quality of the product is improved.

[0010] Further, the upper surface of the hot pressing upper die is provided with an upper heat conduction plate and an upper heat insulation plate, the lower surface of the hot pressing lower die is provided with a lower heat conduction plate and a lower heat insulation plate, the upper heat conduction plate and the lower heat conduction plate are both matched with a plurality of heating rods through heating holes, the upper end of the upper heat insulation plate is connected with the output shaft of the driving device, and the lower end of the lower heat insulation plate is fixedly matched with the upper surface of the base.

[0011] Based on the above, the plurality of heating rods are equidistantly and uniformly distributed, so that the hot pressing upper die and the hot pressing lower die can be uniformly and simultaneously heated, the temperature difference of different positions is avoided, and the processing quality is affected.

[0012] Further, the upper heat conduction plate and the lower heat conduction plate are further provided with temperature sensors, and the temperature sensors are connected with the electrical unit in the control box.

[0013] Based on the above, the sensor can transmit the temperature on the heating die to the control box in real time, and the control box can regulate the temperature of the heating rod after receiving the signal.

[0014] Further, the processing surface of the hot pressing die is provided with a circular arc transition surface which is separated in the direction of the arc surface.

[0015] Based on the above, when the fire tube is pressed, the circular arc transition surface plays a role in deformation transition, and prevents the pipe from being broken due to excessive local stress.

[0016] Further, the hot pressing upper die and the hot pressing lower die are further provided with a guide rod.

[0017] Based on the above, when the hot pressing upper die is pressed downward, the guide rod guides the hot pressing upper die, so that the operation of the device is more stable, the service life of the device is improved while the product quality is ensured.

[0018] In order to make the above features of the utility model and the purposes to be achieved more clearly, the utility model will be further described in combination with the drawings and specific embodiments. BRIEF DESCRIPTION OF DRAWINGS
