Description

Technical Field

[0002] Screws are commonly used fasteners, widely used in various fields due to their advantages such as self-locking, simple manufacturing, mass production, low cost, and interchangeability. Screws consist of two parts: a nut and a pointed screw. The screw has an external thread. As the screw rotates, the threads, under pressure, automatically penetrate into the threaded bottom hole on the workpiece. The external thread on the screw achieves axial self-locking. After production, screws require heat treatment to enhance their strength. Existing screw heat treatment equipment is mostly heat treatment furnaces.

[0003] When the screws are cooled, they are usually immersed in a cooling pool in a barreled manner. Due to the stacking of the bolts, contact surfaces are easily generated between the bolts. Due to the generation of contact surfaces, the screws are easily cooled incompletely, which ultimately leads to a decrease in screw performance.

Through the sliding connection with the slide rail 221, the output rod of the two-way cylinder 222 is not subjected to force, preventing the output rod from bending under force. The output end of the hydraulic push rod 1 223 is fixedly installed with a splint 1 225, and the output end of the hydraulic push rod 2 224 is fixedly installed with a splint 2 226. A rotating clamp 12 is slidably installed on the frame 1, and a rotating clamp 2 13 is slidably installed on the shell 2. The rotating clamp 12 and the rotating clamp 2 13 are symmetrically arranged. The rotating clamp 12 and the rotating clamp 2 13 clamp and rotate the pallet so that the bolts can fall into the cooling pool 3.

[0025] The linear slide 21 includes a slide seat 211 , and the slide rail 221 is fixedly connected to the slide seat 211 . The slide seat 211 drives the slide rail 221 to move, thereby driving subsequent components to move.

[0026] The output ends of the bidirectional cylinder 222 are fixedly connected to slide 227 and slide 3 228 respectively. Slide 227 is fixedly connected to hydraulic push rod 1 223, and slide 3 228 is fixedly connected to hydraulic push rod 2 224.

By setting the slide rod 2 19, the output end of the electric push rod 2 17 is prevented from being subjected to force.

[0029] The cooling pool 3 is provided with a second conveyor 31, which is a mesh conveyor. The water flows back into the cooling pool 3 through the mesh. The conveyor 31 is provided with multiple baffles 32, through which the bolts fall into the cooling pool 3. By immersing the bolts and adjusting the conveying speed of the second conveyor 31, the immersion cooling time of the bolts is guaranteed.

[0030] The specific operation is as follows: the pallet with the bolts is moved from one side of the conveyor 11 to the bottom of the shell 2, the controller controls the clamping device 22 to clamp the pallet, the linear slide 21 moves the slide rail 221, and the two-way cylinder 222 shortens the distance between the hydraulic push rod 1 223 and the hydraulic push rod 2 224. The hydraulic push rod 1 223 and the hydraulic push rod 2 224 respectively push the clamping plate 1 225 and the clamping plate 2 226 at the output end to clamp the pallet. After clamping the pallet, the controller controls the linear slide 21 to move to the top of the cooling pool 3, and the hydraulic push rod 1 223 and the hydraulic push rod 2 224 lower the height of the pallet. The electric push rod 16 and the electric push rod 224 are used to press the pallet. Push rod 2 17 pushes rotating jaw 12 and rotating jaw 2 13, so that rotating jaw 12 and rotating jaw 2 13 can clamp the pallet. At this time, the two-way cylinder 222 is actuated to make clamp plate 1 225 and clamp plate 2 226 not clamp the pallet. Rotating jaw 12 and rotating jaw 2 13 drive the pallet to rotate. The speed at which the bolt falls into the cooling pool 3 can be controlled by adjusting the rotation speed. After rotating jaw 12 and rotating jaw 2 13 drive the pallet to rotate and reset, clamp plate 1 225 and clamp plate 2 226 re-clamp the pallet and place it on conveyor 11 to transport the pallet. The operation is repeated for subsequent pallets.
