Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, and particularly relates to a continuous sintering furnace. Background Art

[0002] The pump tube material plays a crucial role in the automobile cooling system. As a key component connecting various parts, its quality and performance directly affect the stability and efficiency of the entire system. Therefore, in order to ensure that the pump tube material can work effectively for a long time and extend its service life, a series of fine processing procedures must be carried out on it.

[0003] Among these procedures, spraying a wear-resistant coating on the surface of the pump tube material is a crucial step. This process can not only improve the wear resistance of the pump tube, but also enhance its corrosion resistance to a certain extent, so as to maintain the integrity and functionality of the pump tube in a harsh working environment. In order to ensure that the wear-resistant coating can be evenly and firmly attached to the surface of the pump tube, a series of preparatory work needs to be carried out. For example, when sintering the wear-resistant coating on the surface of the pump tube material, the surface of the pump tube needs to be dried first.

[0004] At present, sintering and drying need to be carried out on two different devices, namely a drying oven and a sintering furnace respectively. After the pump tube is dried, the material needs to be transferred to the sintering furnace for sintering, with low efficiency and complex steps. In addition, currently, the pump tubes need to be manually placed horizontally. Since the width of the sintering furnace is generally up to one meter, when placing the pump tubes on the far side of the conveyor belt, the operating distance is far, the operating speed is slow, and the operating difficulty is great.

[0032] The following Figures 1 to 3 describes the embodiments of the present utility model.

[0033] This embodiment relates to a continuous sintering furnace, which can conveniently and evenly distribute the feeding in the width direction of the conveyor belt.

[0034] The continuous sintering furnace in this embodiment includes:

[0035] A frame 1;

[0036] A furnace body 2, the furnace body 2 is provided on the frame 1, the furnace body 2 includes a first heating zone and a second heating zone, the furnace body 2 further includes a first conveyor belt (not shown in the figure), the first heating zone is used for drying the pump tube, and the second heating zone is used for sintering the pump tube;

[0037] A feeding mechanism, the feeding mechanism includes a feeding conveyor belt 31 and a discharging assembly, the discharging assembly is provided beside the feeding conveyor belt 31, and the discharging assembly is used for arranging the pump tubes at intervals on the feeding conveyor belt 31.

[0038] This continuous sintering furnace realizes the automatic arrangement of the pump tubes at intervals through the configuration of the feeding mechanism, so that when supplied to the tunnel furnace, the surfaces of each pump tube are evenly heated, ensuring the heat treatment effect of the pump tube. During operation, the pump tubes are arranged along the width direction of the feeding conveyor belt 31 by using the discharging assembly, and under the drive of the feeding conveyor belt 31, the first

[0039] Drying and sintering are two different processes. Although both drying and sintering process the pump tube by heating as a whole, the heating temperature for drying generally ranges from 50°C to 80°C, and the sintering temperature varies depending on the sintered powder material, usually between 600°C and 1000°C. Taking the sintering of a copper-based material on the surface of the pump tube to increase wear resistance as an example, the sintering temperature is preferably around 850°C. After the pump tube material is cleaned, it is sent to the first heating zone for drying and then enters the second heating zone for sintering, finally obtaining a surface-strengthened pump tube.

[0040] The feeding mechanism further includes a plurality of arranging channels 30 formed by baffles 32. The arranging channels 30 include an inlet and an outlet. The inlets are arranged at intervals along the feeding direction of the feeding conveyor belt 31, and the outlets are arranged at intervals along the width direction of the feeding conveyor belt 31. The inlets of the plurality of arranging channels 30 are arranged along the feeding direction, while the outlets are arranged along the width direction. The operator feeds materials on both sides of the feeding conveyor belt 31 in the feeding direction. The pump tubes can be placed into different inlets of the arranging channels 30 to realize the arrangement of the pump tubes along the width direction, reducing the operation difficulty of the operator.

[0041] The baffle 32 includes a plurality of plate bodies. The plurality of plate bodies are sequentially hinged through a locking structure. The locking structure includes a screw 51, a nut (not shown in the figure), a connecting cylinder 52, and a connecting block 53. The connecting cylinder 52 and the connecting block 53 are respectively arranged on two different plate bodies. The connecting cylinder 52 and the connecting block 53 are jointly penetrated by a through hole. The screw 51 passes through the through hole and is threadedly connected to the nut to clamp and fix the connecting cylinder 52 and the connecting block 53. The baffle 32 is arranged as a plurality of plate bodies connected by a locking structure, and the locking structure enables the angle of the plate bodies to be adjusted so as to adjust the position of the outlet of the arranging channel 30 in the width direction of the conveyor belt to adapt to pump tubes of different sizes.

[0042] Specifically, the baffle 32 includes a first sub-plate 321 and a second sub-plate 322. The connecting cylinder 52 is arranged on the first sub-plate 321, and the connecting block 53 is arranged on the second sub-plate 322. In this embodiment, the first sub-plate 321 and the second sub-plate 322 rotate around the screw 51 passing through the through hole to change the relative positions of the first sub-plate 321 and the second sub-plate 322, and the position of the end of the arranging channel 30 in the width direction of the conveyor belt can be adjusted to adjust the position of the pump tube flowing out of the arranging channel 30. In this embodiment, the first sub-plate 321 is locked to the truss through the screw 51.

[0043] Further, a brush 42 is provided on the second sub-board 322, and the brush 42 is provided on one side of the second sub-board 322 in the arrangement channel 30. By providing the brush 42 on the second sub-board 322, the pump tube can be cleaned, and impurities on the outer surface of the pump tube can be reduced. In this embodiment, a copper-based material needs to be sintered on the inner surface of the pump tube. Before sintering, the copper-based material powder is impregnated with an adhesive and bonded to the inner side of the pump tube. Then, when the pump tube is fed into the tunnel furnace, under the action of high temperature, the copper-based material is directly sintered on the inner side of the pump tube.

[0044] Further, the continuous sintering furnace further includes a dust suction mechanism, and the dust suction mechanism is provided on one side of the second sub-board 322 along the conveying direction of the conveyor belt. After the dust suction mechanism is provided, the dust brushed up by the brush 42 can be sucked into the pump tube, ensuring a clean environment.

[0045] The dust suction mechanism includes a dust suction hood 41, a negative pressure pump, and a connecting pipe. The dust suction hood 41 is at the end of the second sub-board 322, the negative pressure pump is provided on the frame 1, and the negative pressure pump is communicated with the dust suction hood 41 through the connecting pipe. When the negative pressure pump works, it sucks dust at the end of the second sub-board 322, that is, the end of the arrangement channel 30, through the connecting pipe, avoiding the dust from spreading in the air. This structure can conveniently realize the function of negative pressure dust suction.
