The invention discloses a chrome steel shot and a production method, which belongs to the technical field of chrome steel shot production. The steps include: heating the semi-finished chrome steel shot to 840°C in a continuous rotating drum heat treatment furnace for 20-40 minutes, performing a first quenching treatment by air cooling quenching, and performing a tempering treatment at 450-500°C for 50-80 minutes; then performing a second cold quenching by spraying water mist, and finally placing the shot in a 200-230°C furnace for 3-5 hours and then taking the shot out of the furnace for air cooling to obtain the finished chrome steel shot. The beneficial effects of the invention are: adding vanadium to the formula to obtain chrome steel shots with superior toughness, strength and wear resistance compared to high carbon cast steel shots and alloy steel shots; using CO / N 2 The mixed gas is used for the first quenching treatment by air cooling, which can make the added vanadium in the CO / N 2 Under the action of high temperature, nano-scale V (C, N) matrix grains are uniformly formed, which further greatly improves the strength and toughness and has better overall wear resistance.

The utility model discloses a spring connecting rod tool and relates to the technical field of spring connecting rods. The utility model discloses a spring connecting rod tool. Comprising a lower mounting disc, a middle mounting disc arranged above the lower mounting disc, an upper mounting disc arranged above the middle mounting disc, a connecting rod which is arranged on the lower mounting disc and penetrates through the middle mounting disc, an upper supporting block and a lower supporting block which are arranged on the outer side of the connecting rod, and a spring which is arranged between the upper supporting block and the lower supporting block and surrounds the connecting rod, the extension rod is fixed to the top of the connecting rod and penetrates through the upper mounting disc, the upper supporting block supports the middle mounting disc, a jack space is formed between the middle mounting disc and the upper mounting disc, a lead screw penetrating through the middle mounting disc and the upper mounting disc is fixedly mounted on the lower mounting disc, and the outer side of the lead screw is in threaded connection with nuts located at the top of the middle mounting disc and the top of the upper mounting disc.
