Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, and in particular to a sintering apparatus for powder metallurgy. Background Technology

[0002] Powder metallurgy is a process technology that uses metal powder (or a mixture of metal powder and non-metal powder) as raw material and processes it into metal materials, composite materials and various types of products through forming and sintering. Its basic principle is to generate atomic metals by uniformly mixing metal powder, non-metal powder and additives, and then to achieve the specified size and shape and good performance through forming and sintering steps.

[0003] Existing powder metallurgy sintering equipment typically places the billet to be sintered in a placement tray, which is then placed on a conveyor belt. The conveyor belt then carries the billet into the sintering furnace for heating and cooling. After sintering, the placement tray and the sintered billet on it need to be removed manually. However, since the billet has just cooled, the placement tray cannot be guaranteed to be at room temperature. Operators need to directly contact the placement tray, and the high temperature of the tray can cause burns to their skin. After the billet reaches room temperature, the billet on the placement tray needs to be removed one by one and stored in the tray, which takes a lot of time and effort and further reduces production efficiency.

[0004] Therefore, it is necessary to provide a new sintering apparatus for powder metallurgy to solve the above-mentioned technical problems. Summary of the Invention

A push plate for pushing the blank on the placement tray to the belt conveyor is provided on the surface of the vertical plate, which can be moved back and forth. A positioning rod for positioning the placement tray is provided on the surface of the vertical plate and behind the push plate. A collection box for collecting the placement tray is provided at the rear end of the crawler conveyor belt, and a receiving tray is provided above the inner cavity of the collection box.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of a preferred embodiment of a sintering apparatus for powder metallurgy provided by this utility model; Figure 2 for Figure 1 The diagram shows the side structure. Figure 3 for Figure 1 The diagram shows a top view of the storage box. A sintering device for powder metallurgy includes a tracked conveyor belt 1, a sintering furnace 2 disposed in the middle of the tracked conveyor belt 1, and a plurality of placement trays 19 for placing blanks are placed at intervals on the tracked conveyor belt 1, with thicknesses at both ends of the placement trays 19;

[0022] Two limiting rods 3 are provided on one side of the upper rear end of the crawler conveyor belt 1 for limiting the placement tray 19. A belt conveyor belt 10 is provided on one side of the rear end of the crawler conveyor belt 1. A vertical plate 4 is provided on the other side of the rear end of the crawler conveyor belt 1. A push plate 5 is provided on the surface of the vertical plate 4 for pushing the blank on the placement tray 19 to the belt conveyor belt 10. A positioning rod 6 for positioning the placement tray 19 is provided on the surface of the vertical plate 4 and behind the push plate 5. A collection box 8 for collecting the placement tray 19 is provided at the rear end of the crawler conveyor belt 1. A receiving tray 16 is provided above the inner cavity of the collection box 8.

[0023] The tracked conveyor belt 1 is responsible for transporting the placement tray 19 containing the blanks from one end to the other, passing through the sintering furnace 2 for heating treatment along the way.

[0024] The placement tray 19 has thicknesses at both ends to ensure that after the material is unloaded, it can be manually removed by hand.

[0025] The purpose of not setting thickness on both sides of the placement tray 19 is so that when the placement tray 19 moves to the rear end of the crawler conveyor belt 1, the blanks on the placement tray 19 can be pushed out by the push plate 5 on one side, eliminating the need for manual removal of them one by one, thus improving work efficiency.

[0026] The limiting rod 3 is used to prevent the placement plate 19 from moving synchronously with the limit rod 3 when the blank needs to be pushed out when the placement plate 19 moves to the rear end.

[0027] When the positioning rod 6 descends to fit against the placement tray 19, it is used to position the placement tray 19 at the rear end of the crawler conveyor belt 1 and push the blank on the placement tray 19 onto the belt conveyor belt 10.

[0028] After the material is unloaded, it rises via the positioning rod 6, and then moves backward via the crawler conveyor belt 1 to the placement tray 19, thus falling onto the receiving tray 16.

[0029] The storage box 8 is used to collect empty placement trays 19, and the receiving tray 16 is used to receive the placement trays 19. When the placement tray 19 falls onto the receiving tray 16, the placement tray 19 can be pulled into the storage box 8 by retracting the receiving tray 16, so that they can be arranged.

[0030] The blank is placed on the placement tray 19 and then transported to the sintering furnace 2 for heating via the crawler conveyor belt 1. After sintering, the drive positioning rod 6 is lowered to be flush with the placement tray 19. Then, the drive push plate 5 pushes the blank from the placement tray 19 onto the belt conveyor belt 10. Then, the positioning rod 6 is raised, and the empty placement tray 19 is driven to fall into the receiving frame 8 via the crawler conveyor belt 1. Then, the blank is arranged by the receiving tray 16.

[0031] A first electric telescopic rod 13 is horizontally arranged at the rear end of the middle part of the vertical plate 4, and the push plate 5 is fixedly connected to one end of the first electric telescopic rod 13.

[0032] The first electric telescopic rod 13 is activated to extend and retract, which drives the push plate 5 to move forward. The push plate 5 pushes the blank on the placement plate 19 onto the belt conveyor 10.

[0033] The rear side of the vertical plate 4 is provided with an elongated groove, and an electric slide rail 11 is provided in the elongated groove. A sliding block 12 is slidably provided on the surface of the electric slide rail 11, and the positioning rod 6 is fixedly connected to the surface of the sliding block 12.

[0034] When it is necessary to unload the blank on the placement tray 19, the sliding block 12 is driven to slide by controlling the electric slide rail 11, thereby driving the positioning rod 6 to slide along its length direction, and driving the positioning rod 6 to descend to fit against the placement tray 19, thereby positioning it.

[0035] After the material is unloaded, the sliding block 12 is moved by controlling the electric slide rail 11, which in turn moves the positioning rod 6 along its length and causes the positioning rod 6 to rise, thereby releasing it from the positioning.

[0036] Both sides of the tracked conveyor belt 1 are inclinedly provided with horizontal plates 7 extending into the storage box 8. Several rotating rollers 15 are rotatably arranged between the two horizontal plates 7. Each horizontal plate 7 is provided with a baffle 14 on its side. The rear side of the tracked conveyor belt 1 is inclinedly provided with a guide plate 9 extending into the belt conveyor belt 10.

[0037] The placement tray 19 is placed on the crawler conveyor belt 1 and conveyed forward with the movement of the crawler conveyor belt 1. When the placement tray 19 reaches the end of the crawler conveyor belt 1, it slides down along the cross plate 7 under the action of gravity. The material is conveyed on the cross plate 7 by the auxiliary conveying of the rotating roller 15, which further reduces the friction between the material and the cross plate 7 and improves the conveying efficiency.

[0038] Baffles 14 are also provided on both sides of the guide plate 9 to prevent it from flowing out from the sides when falling.

[0039] The billet slides down the horizontal plate 7 through the push plate 5 into the storage box 8, completing the collection of the billet. It does not require manual removal of the billet one by one, which improves work efficiency and reduces manual labor.

[0040] The receiving tray 16 extends to the outside of the storage box 8 and is fixedly connected to a connecting plate 17. A second electric telescopic rod 18 is horizontally arranged on the side wall of the storage box 8, and one end of the second electric telescopic rod 18 is fixedly connected to the surface of the connecting plate 17.

[0041] When the placement tray 19 falls onto the receiving tray 16, the second electric telescopic rod 18 is activated to extend, thereby moving the receiving tray 16 outward. Since the placement tray 19 is in contact with the inner wall of the receiving box 8, the placement tray 19 falls into the receiving box 8 for storage and arrangement. After the placement tray 19 falls into the receiving box 8, the second electric telescopic rod 18 is then retracted to move the receiving tray 16 back to its original position to receive the next placement tray 19.

[0042] The sintering furnace 2 is equipped with a waste gas outlet pipe 20 at the top.

[0043] The main purpose of the exhaust gas outlet pipe 20 is to discharge the exhaust gas generated by the sintering furnace 2 during the sintering process into the external environment, so as to ensure air circulation and exhaust gas treatment inside the sintering furnace.

[0044] The working principle of the sintering device for powder metallurgy provided by this utility model is as follows:

[0045] First, the blank is placed on the placement tray 19, and then transported to the sintering furnace 2 for heating treatment by the crawler conveyor belt 1. After sintering, the drive positioning rod 6 is lowered to be flush with the placement tray 19. Then, the drive push plate 5 pushes the blank from the placement tray 19 onto the belt conveyor belt 10. Then, the positioning rod 6 is raised, and the empty placement tray 19 is driven to fall into the receiving frame 8 by the crawler conveyor belt 1. Then, the blank is arranged by the receiving tray 16.

[0046] Compared with related technologies, the sintering apparatus for powder metallurgy provided by this utility model has the following beneficial effects:

[0047] This invention provides a sintering device for powder metallurgy. First, the blank is placed on the placement tray 19, and then transported to the sintering furnace 2 for heating via the crawler conveyor belt 1.

This reduces direct contact between personnel and the high-temperature sintering furnace, reduces the risk of workplace injuries, and reduces the time and cost of manual handling, thereby improving overall production efficiency.
