Abstract

The utility model disclosing a press belonging to the technical field of general machine tools comprises a crankshaft which comprises a main shaft and cranks, connecting bars, a press body, a slide rail which is arranged on the press body, and an upper slide block which is connected with the upper ends of the connecting rods by a bearing, wherein, both ends of the main shaft are fixed to the machine body by bearings, and the cranks are connected with the lower ends of the connecting rods by the bearing; the upper slide block is arranged in the slide rail which is in the same direction with the axial line of the connecting rods; two cranks are provided and are arranged symmetrically on both sides of the main shaft; each of the two sides of the upper slide block is provided with a connecting rod. The press further comprises a lower slide block, cam wheels and a lower slide rail, wherein, two cam wheels which are fixed to the main shaft are provided; two bearings which are fixedly arranged on the left side and the right side of the lower slide block are respectively against the working surfaces of the two cam wheels; the lower slide block is arranged in the lower slide rail which is arranged in the press body. The utility model has the advantages of compact structure, less working stations, small processing space and high efficiency and processing precision.

Description

A kind of forcing press

Technical field

The utility model relates to a kind of forcing press, belongs to the universal machine tools technical field.

Background technology

In the prior art, a kind of single sliding block forcing press is arranged, comprise bent axle, connecting rod, fuselage, slide rail and top shoe, described bent axle comprises main shaft and crank, described crank has two and be symmetricly set in the main shaft both sides, the main shaft two ends by bearing fixing on fuselage, small end is connected with crank by bearing, the connecting rod lower end is connected with slide block, and top shoe is arranged in direction and connecting rod axis slide rail in the same way, also is provided with workbench on the fuselage, during use, the patrix of mould is fixed on the top shoe, the counterdie of mould is fixed on the workbench, bent axle rotates under external force, the drivening rod motion, connecting rod drives top shoe and pumps along slide rail, and workpiece is put into, between the counterdie, patrix moves downward with counterdie contact position place workpiece is pressed into required form.Its weak point is: the workpiece punch forming is often needed multiple working procedure, and its station divides spreading, and requisite space is big.

The utility model content

The purpose of this utility model provides a kind of forcing press, makes its compact conformation, and station is few, and processing space is little, efficient and machining accuracy height.

The purpose of this utility model is achieved in that a kind of forcing press, comprise bent axle, connecting rod, fuselage, slide rail and top shoe, described bent axle comprises main shaft and crank, the main shaft two ends by bearing fixing on fuselage, crank is connected by bearing with the connecting rod lower end, small end is connected with top shoe by bearing, top shoe is arranged in direction and connecting rod axis slide rail in the same way, described slide rail is arranged on the fuselage, described crank has two and be symmetricly set in the main shaft both sides, described top shoe both sides respectively are provided with a connecting rod, described forcing press also comprises sliding block, cam and glidepath, cam have two and be fixed on the main shaft, and the sliding block left and right sides is fixed with bearing respectively, two bearings on the described sliding block is conflicted respectively on two cam working faces, and sliding block is positioned at the glidepath that is arranged on the fuselage.

During the utility model work, the patrix of mould is fixed on the top shoe, the counterdie of mould is fixed on the sliding block, bent axle rotates under external force, the drivening rod motion, and connecting rod drives top shoe and pumps along slide rail, simultaneously, cam rotates with bent axle, and cam promotes counterdie and also pumps the upper die and lower die acting in conjunction, can be simultaneously from last, following both direction works the work piece into type, therefore, the utility model station is few, compact conformation, owing to reduced the transfer of workpiece between each station, also promptly reduced the location number of times, therefore, machining accuracy has been improved.

As further improvement of the utility model, described slide rail extends downwards and glidepath is connected as a single entity.The shared slide rail of last top shoe and sliding block can make processing easier, can save manufacturing cost.

Description of drawings

Fig. 1 is the utility model structural representation.

Wherein, 1 top shoe, 2 connecting rods, 3, sliding block, 4 cams, 5 main shafts, 6 cranks, 7 bearings, 8 fuselages, 9 slide rails.

The specific embodiment

As figure, a kind of forcing press, mainly by bent axle, connecting rod 2, fuselage 8, slide rail 9, top shoe 1, sliding block 3, cam 4 formations such as grade, described bent axle is made of main shaft 5 and crank 6, crank 6 has two and be symmetricly set in the both sides of main shaft 5, main shaft 5 two ends by bearing fixing on fuselage 8, top shoe 1 both sides respectively are provided with a connecting rod 2, two cranks 6 are connected by bearing with two connecting rods, 2 lower ends, connecting rod 2 upper ends are connected with top shoe 1 by bearing, top shoe 1 is arranged in the axis slide rail 9 in the same way of direction and connecting rod 2, and described slide rail 9 is arranged on the fuselage 8, and slide rail 9 extends downward sliding block 3 both sides, cam 4 has two and be fixed on the main shaft 5, sliding block about 3 two downsides are fixed with bearing 7 respectively, and the two bearings 7 on the described sliding block is conflicted respectively on the working face of two cams 4, and sliding block 3 is positioned at described slide rail 9.
