[0002] The bar and wire cooling bed is an important link in the production process. After the finished bars are rolled, they need to be put on the cooling bed for natural cooling. During the production process, if the temperature is not well controlled or affected by the ambient temperature, the heads and tails of the bars on the cooling bed will bend. However, the bending of the heads and tails of the bars will cause the following problems: 1. The bending of the heads and tails of the finished products will affect the appearance quality and cause quality objections; 2. The bending of the heads and tails of the finished products will affect the yield rate and the cut-to-length rate indicators, and a large amount of loss will increase the processing cost; 3. The bending of the heads and tails will affect the entire production rhythm during the cut-to-length shearing process; 4. The bending of the heads and tails will cause the bars to pop out of the groove during the collection process, damaging the equipment and increasing safety risks.

[0019] Preferably, tooth grooves 6 are provided on the side walls on the opposite sides of the two clamping blocks 3. The design of the tooth grooves 6 facilitates the clamping blocks 3 to better clamp the head and tail ends of the rod.

[0020] Preferably, a plurality of first compression springs 7 are evenly spaced on the baffle plate on one side of the clamping block 3, and a stop plate 8 is connected to the end of the first compression spring 7 facing away from the baffle plate. The displacement sensor is arranged on the stop plate 8. The arrangement of the first compression spring 7 and the stop plate 8 facilitates the first compression spring 7 to have a certain buffering effect on the rod head when the rod head reaches the stop plate 8.

[0021] Preferably, the inverted L-shaped bases 1 on both sides of the double-headed cylinder 5 are vertically connected to support rods 9, and long strip-shaped cushion blocks 10 are horizontally provided at the ends of the two support rods 9.

[0022] The inverted L-shaped base 1 on both sides of the preferred double-head cylinder 5 is provided with a through hole suitable for the movement of the support rod 9. The two support rods 9 pass through the through holes and extend to the outside of the bottom end of the inverted L-shaped base 1.

[0023] Working principle: When the rod reaches the baffle 8 from one end of the rod wire cooling bed, the elastic rod buffer provided by the first compression spring 7 stops. At this time, the displacement sensor receives the signal and transmits it to the controller, and the controller controls the two double-headed cylinders 5 at both ends of the cooling bed to start quickly. The output shafts at both ends of the double-headed cylinder 5 pull the two connecting rods 4 connected to it. At this time, the two clamping blocks 3 at the head and tail ends of the cooling bed can move relative to each other and clamp and straighten the head and tail ends of the rod, so as to avoid bending at the head and tail ends of the rod to ensure the quality of the rod.
