Description

Four-column type fast energy-saving single action hydraulic stamping press

Technical field

The utility model relates to a kind of sheet stamping equipment, relates in particular to four-column type fast energy-saving single action hydraulic stamping press.

Background technology

General four-column type single action hydraulic stamping press is made of parts such as column, upper beam, slide block, base, travelling table, master cylinder, adjusting nut and locking nuts, wherein four root posts by the rectangular distribution, upper beam, slide block and base are sleeved on the column from top to bottom successively, wherein upper beam and base are fixed on the upper/lower terminal of column respectively by adjusting nut and locking nut, slide block is installed on the guide pillar face, this slide block is connected with upper beam by two master cylinders, and slide block is controlled by master cylinder moving up and down of vertical direction.Travelling table is installed in the top of base, and can move forward and backward on horizontal plane, so that place sheet material to be processed and the plate of machine-shaping is taken out.Because two master cylinders that existing four post single action sheet stamping machines are adopted are piston cylinder, the idle running of slide block descends speed will overcome the resistance of two piston cylinder cavity of resorption area pressure oil and the flow that cavity area under two piston cylinders is passed through in backhaul soon like this, so speed is all slower, wherein idle running descends soon that speed is approximately 100-250mm/s, opening speed is approximately 60-180mm/s, therefore causes efficiency of equipment lower; Simultaneously, because two piston cylinders all have the factor of following cavity area during the descending and backhaul of idle running, cause the energy consumption of equipment higher.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of idle running to descend speed and opening speed is very fast, energy consumption is lower four-column type fast energy-saving single action hydraulic stamping press soon.

The technical solution of the utility model is as follows: a kind of four-column type fast energy-saving single action hydraulic stamping press, comprise column, put the beams in place, slide block, base, travelling table and master cylinder, wherein four root posts by the rectangular distribution, upper beam and base are respectively on column, following two ends, fix by adjusting nut and locking nut, slide block is between upper beam and base, and can on the sliding surface of column, do operation up and down, its key is: described master cylinder is a piston cylinder, the cylinder body of this piston cylinder is fixed on the corresponding positions, center central and four rectangles that column forms of putting the beams in place, the piston rod of piston cylinder straight down, and the central authorities of the lower end of piston rod and slide block fixedly connected; Respectively be provided with an auxiliary cylinder in the both sides of described master cylinder, this auxiliary cylinder is a plunger case, and the cylinder body of plunger case is fixed on the upper beam, and the plunger of plunger case and is fixedlyed connected with described slide block straight down.

Adopt above technical scheme, put the beams in place with slide block between be connected by three oil cylinders, wherein Zhong Jian master cylinder is a piston cylinder, the auxiliary cylinder of both sides is a plunger case, slide block is mainly provided by piston cylinder along the upper and lower executing agency that moves of column, two plunger cases help out, and the idle running of slide block descends speed to rise to 250-450mm/s by the 100-250mm/s of former equipment on year-on-year basis soon like this, about being doubled; The opening speed of slide block rises to 120-220mm/s by the 60-180mm/s of former equipment on year-on-year basis, has also improved about 50%.Simultaneously, have only piston cylinder of master cylinder that following cavity area is arranged during backhaul, thereby greatly reduce the energy consumption of equipment.

Slide block operates steadily when guaranteeing oil cylinder work, net synchronization capability is good, and above-mentioned two auxiliary cylinders are symmetrical distribution in the both sides of master cylinder, and three's axial line is in same plane.

Beneficial effect: the utility model can improve the idle running of slide block greatly and descend speed and opening speed soon, when reducing equipment energy consumption, has effectively improved efficiency of equipment, has characteristics such as design is ingenious, enforcement is easy, is suitable for large-scale promotion and uses.
