Description

Technical Field

[0001] This utility model relates to the field of tappet manufacturing technology, specifically to a tappet manufacturing annealing device. Background Technology

[0002] Tappets play a role in transmitting force in the valve train. As the follower of the cam, the tappet's function is to transmit the motion and force from the cam to the pushrod or valve. It also bears the lateral force applied by the cam and transmits it to the engine block or cylinder head. Tappets are made of materials such as carbon steel, alloy steel, nickel-chromium alloy cast iron, and chilled alloy cast iron. Tappets can be divided into two main categories: mechanical tappets and hydraulic tappets. Each category has various structural forms such as planar tappets and hydraulic tappets.

[0003] During production, tappets require annealing, a metal heat treatment process that involves slowly heating the metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. Traditionally, tappets employ two cooling methods during annealing: one is furnace cooling, which requires a long waiting time and is inefficient for production; the other is spray cooling, but this method typically only cools one side of the tappet, resulting in uneven annealing and reduced production efficiency.

[0032] The working principle is as follows:

[0033] In use, after the tappet is heated in the furnace, it is placed between two arc-shaped clamping plates 803. By activating two electric push rods 802, the two arc-shaped clamping plates 803 clamp and fix the heated tappet. Then, the displacement motor 301 is activated, driving the threaded rod 302 to rotate. The threaded rod 302 drives the threaded sleeve 303 to move to the left, thus inserting the tappet into the annealing box 1 through the feed port 6. Then, the coolant is delivered to the spray nozzle 5 via the water pipe 4 for spraying the tappet with coolant during annealing. Simultaneously, the tilting motor 702 is activated, driving the tilting plate 703 to rotate, which in turn drives the concave frame 80... 1. Rotation causes the clamped and positioned tappet to flip, allowing coolant to be evenly sprayed onto its outer surface, improving the annealing effect. After annealing, displacement motor 301 drives threaded rod 302 to rotate in the opposite direction, moving the tappet out of the annealing chamber 1. Finally, steering motor 1101 drives drive gear 1104 to rotate, which in turn drives driven gear 1103 to rotate. Driven gear 1103 then drives transmission rod 1102 to rotate, turning the tappet to the right. This facilitates its movement to the next machining step, improving the tappet's machining efficiency.

[0034] In summary, this tappet annealing device, through the clamping assembly 8, can clamp and fix the heated tappet. Through the displacement assembly 3, it can drive the tappet to be inserted into the annealing box 1 from the feed port 6. The water supply pipe 4 and the nozzle 5 spray coolant onto the tappet for annealing. Through the flipping assembly 7, it can drive the tappet to flip, so that the outer surface of the tappet can be evenly sprayed with coolant, improving the annealing effect. Through the steering assembly 11, it can drive the annealed tappet to rotate, so that it can be easily moved to the next processing step by the displacement assembly 3, improving the processing efficiency of the tappet.
