Abstract

The utility model discloses an automatic water-cooling device for a ring rolling machine, which comprises a water pump M, a spraying pipe, a guide rail and a material gathering rod. A pulley wheel of the material gathering rod is installed on the guide rail, and the water pump is connected with a zero line L and a live wire N of a power supply. The automatic water-cooling device for the ring rolling machine is characterized in that a normally closed travel switch SQ1 is arranged on the guide rail between a pneumatic hammer and the ring rolling machine, a normally opened travel switch SQ2 is arranged on the guide rail between the ring rolling machine and a press machine, and a solenoid valve is arranged on the spraying pipe. The normally closed travel switch SQ1, the normally opened travel switch SQ2 and an intermediate relay KA are connected in series and then connected with the water pump M in parallel, a normally opened contact KA-1 of the intermediate relay KA is connected with the normally opened travel switch SQ2 in parallel, and a normally opened contact KA-2 of the intermediate relay KA is connected with a coil C of the solenoid valve in series and then connected with the water pump M in parallel. The automatic water-cooling device for the ring rolling machine is simple in structure and convenient to use, performs intermittent spraying and cooling to a rolling shaft of the ring rolling machine, does not reduce processing temperature of workpieces and improves processing efficiency and quality.

Description

Ring Rolling Machine is used automatic water-cooling apparatus

Technical field

The utility model relates to the improvement of a kind of Ring Rolling Machine with water cooling plant, and specifically a kind of Ring Rolling Machine is used automatic water-cooling apparatus.

Background technology

At present, Ring Rolling Machine adds man-hour to workpiece, generally needs pneumatic hammer that workpiece is forged earlier, after waiting to forge completion; Provoke workpiece with gathering iron, move to Ring Rolling Machine along guide rail and carry out reaming, after reaming is accomplished; By gathering iron workpiece is transported to forcing press again and processes, gathering iron turns back to the pneumatic hammer place along guide rail once more and transports next time, in entire work process; Because the rolling axle on the Ring Rolling Machine needs cooling, generally uses water pump to draw water and carries out water-cooled, this water cooling plant comprises water pump and shower; The water pump commentaries on classics of not stopping transport uninterruptedly sprays cooling with shower to the rolling axle on the Ring Rolling Machine all the time, and its weak point is: because shower uninterruptedly sprays the rolling axle on the Ring Rolling Machine; When gathering iron was transported to workpiece and transports Ring Rolling Machine, shower always sprayed water on the workpiece, causes workpiece cooling in various degree; Oxide skin comes off unclean, goes into the secondary oxidation skin, has reduced crudy.

Summary of the invention

It is a kind of simple in structure, easy to use that the purpose of the utility model is to provide, and the rolling axle of Ring Rolling Machine is carried out the intermittent shower cooling, can not reduce the Ring Rolling Machine of workpiece processing temperature and use automatic water-cooling apparatus.

In order to reach above purpose; The technical scheme that the utility model adopted is: Ring Rolling Machine is used automatic water-cooling apparatus; Comprise water pump M, shower, guide rail and gathering iron; The pulley of gathering iron is installed on the guide rail, and water pump M meets the zero line L and the live wire N of power supply, it is characterized in that: on the guide rail between pneumatic hammer and the Ring Rolling Machine, be provided with normally closed travel switch SQ ₁, on the guide rail between Ring Rolling Machine and the forcing press, be provided with and often start Cheng KaiguanS Q ₂, on shower, be provided with magnetic valve, normally closed travel switch SQ ₁, often start Cheng KaiguanS Q ₂After auxiliary reclay KA series connection, parallelly connected with water pump M again, the normally opened contact KA-1 of auxiliary reclay KA and often start Cheng KaiguanS Q ₂Parallel connection, the normally opened contact KA-2 of auxiliary reclay KA is with after the coil C of magnetic valve connects, and is parallelly connected with water pump M again.

The beneficial effect of the utility model is: simple in structure, easy to use, the rolling axle of Ring Rolling Machine is carried out the intermittent shower cooling, and can not reduce the workpiece processing temperature, improved working (machining) efficiency and quality.

Description of drawings

Fig. 1 looks sketch map for the structure master of the utility model;

Fig. 2 is the circuit theory diagrams of the utility model;

Among the figure: 1, water pump M; 2, magnetic valve; 3, shower; 4, normally closed travel switch SQ ₁5, often start Cheng KaiguanS Q ₂6, pneumatic hammer; 7, forcing press; 8, Ring Rolling Machine; 9, guide rail; 10, gathering iron.

The specific embodiment

Make the utility model with reference to accompanying drawing 1,2.This Ring Rolling Machine is used automatic water-cooling apparatus; Comprise water pump M1, shower 3, guide rail 9 and gathering iron 10; The pulley of gathering iron 10 is installed on the guide rail 9, transports workpiece so that gathering iron 10 can slide along guide rail 9, and water pump M1 meets the zero line L and the live wire N of power supply; Water pump M1 is in normally open like this, it is characterized in that: on the guide rail 9 between pneumatic hammer 6 and the Ring Rolling Machine 8, be provided with normally closed travel switch SQ ₁4, on the guide rail 9 between Ring Rolling Machine 8 and the forcing press 7, be provided with and often start Cheng KaiguanS Q ₂5, on shower 3, be provided with magnetic valve 2, normally closed travel switch SQ ₁4, often start Cheng KaiguanS Q ₂5 with auxiliary reclay KA series connection after, parallelly connected with water pump M1 again, the normally opened contact KA-1 of auxiliary reclay KA and often start Cheng KaiguanS Q ₂5 parallel connections, the normally opened contact KA-2 of auxiliary reclay KA is with after the coil C of magnetic valve 2 connects, and is parallelly connected with water pump M1 again.

During work, water pump M1 moves all the time, and gathering iron 10 is provoked workpiece and moved to Ring Rolling Machine 8 from pneumatic hammer 6, meets normally closed travel switch SQ ₁4, normally closed travel switch SQ ₁4 break off then closure of back, run into and often start Cheng KaiguanS Q ₂5, often start Cheng KaiguanS Q ₂5 closed energisings, auxiliary reclay KA energising makes normally opened contact KA-1 and the closed energising of normally opened contact KA-2 of auxiliary reclay KA; Make the coil C energising of magnetic valve 2; Open the valve of magnetic valve 2, shower 3 water sprays cool to Ring Rolling Machine 8, after gathering iron 10 is transported to forcing press 7 with material; Gathering iron 10 returns along guide rail 9, earlier through often starting Cheng KaiguanS Q ₂5, pass through normally closed travel switch SQ again ₁4, at this moment, normally closed travel switch SQ ₁4 break off, and make auxiliary reclay KA outage, and normally opened contact KA-1 and the normally opened contact KA-2 of auxiliary reclay KA become off-state by closure state; The coil C outage of magnetic valve 2, magnetic valve 2 valve-offs, shower 3 are no longer sprayed water; Like this, gathering iron 10 turns back to pneumatic hammer 6 places once more, carries out next operation; So move in circles, improved the crudy of workpiece.
