[0006] Specifically, the connecting piece comprises a connecting plate, the two sides of the water storage chamber adjacent to the quenching furnace are fixedly connected with the connecting plates, the connecting plates are provided between the quenching furnace and the connecting plates, the connecting plates are fixedly connected with the quenching furnace, one side of the connecting plate facing the gasket is provided with a plurality of uniformly arranged small holes, the side of the gasket facing the connecting plate is uniformly provided with a plurality of screw holes aligned with the small holes, the small holes are provided with screws, and one end of the screw is threadedly connected in the screw hole.

[0007] Specifically, the lower surface of the rubber plate is pasted with a heat insulation plate through glue, the movable end of the electric push rod is fixedly connected with the heat insulation plate, and the bottom of the bottom box is provided with a vertical hole, and the movable end of the electric push rod penetrates through the vertical hole.

[0008] Specifically, the upper surface of the bottom cover is provided with a through hole at the middle position, and the through hole is arranged in the water storage chamber.

[0009] Specifically, the upper surface of the floating block is concave downward to form a positioning hole, and the lower end of the rectangular rod is pasted in the positioning hole through glue.

[0010] Specifically, the upper surface of the baffle is fixedly connected with the edge plate at both edges, the edge plate and the baffle are an integral molding structure, and the baffle and the supporting plate are an integral molding structure.

[0011] The beneficial effects of the present application are as follows:

[0012] 1. Place the fasteners in two vibratory feeders. When the feeders are working, the fasteners enter the straight groove one by one. Under the vibration of the vibrator, the fasteners in the straight groove move to the sliding groove. Then, the fasteners roll laterally down the inclined sliding groove into the quenching chamber of the quenching furnace. That is, the fasteners move laterally onto the support plate, so that the fasteners entering the quenching chamber do not overlap each other. The fasteners enter the quenching chamber in a rolling state, which is conducive to heating different areas of the fasteners. The fasteners do not overlap each other, so the fasteners are heated evenly, which is beneficial to improving the quenching quality of the fasteners.

[0013] 2. The baffle prevents the rolling fasteners from slipping off the support plate due to inertia. The baffle and the chute work together to confine the fasteners to the support plate. The electric push rod is retracted, which drives the rubber plate downward, allowing the water in the water storage chamber to flow back into the bottom tank. At this time, the float falls with the drop in water level, and the height of the support roller decreases, causing the baffle to change from an upward tilted state to a horizontal state. At this time, the end of the support plate away from the chute tilts downward, making it easier to remove the heated fasteners. After the electric push rod is extended, the support plate returns to a horizontal state, and the baffle returns to an upward tilted state.

[0014] 3. By causing water to reciprocate between the water storage chamber and the bottom tank, the height of the support roller changes under the action of buoyancy. On the one hand, the water, rubber plate, and heat insulation plate work together to block heat and prevent heat from the baffle from being transferred to the electric push rod and causing damage to it. On the other hand, when the fasteners squeeze the structure formed by the support plate and baffle, the position of the float changes in the water, achieving the purpose of buffering. The rectangular rod and the rectangular hole cooperate with each other to prevent the support roller from rotating. The elbow is installed on the top cover, which facilitates water replenishment through the elbow and helps to maintain the same air pressure inside and outside the water storage chamber.

[0015] 4. Align the small holes on the connecting plate with the screw holes on the pad, then screw the screws through the small holes and into the screw holes to complete the assembly of the water storage chamber and the quenching furnace, thereby locally increasing the thickness of the screw mounting area of ​​the quenching furnace.

[0016] 5. Installing a bottom box at the bottom of the water storage chamber and arranging the bottom box horizontally, as well as arranging the water storage chamber vertically, helps to reduce the height occupied by the structure formed by the bottom box and the water storage chamber.
