Abstract
The utility model relates to a crankshaft connecting rod system of a warm forging press machine. The crankshaft connecting rod system comprises a crankshaft and a connection rod, wherein the crankshaft is formed by a main shaft neck and a connecting rod shaft neck. The crankshaft is characterized in that the connecting rod shaft neck is formed by a first connecting rod shaft neck and a second connecting rod shaft neck possessing the same shaft diameter, wherein the first and the second connecting rod shaft necks are respectively co-axially and eccentrically arranged on the main shaft neck at a preset interval. The connecting rod is formed by a first connecting rod and a second connecting rod, wherein the first connecting rod and the second connecting rod are respectively arranged on the corresponding first connecting rod shaft neck and the second connecting rod shaft neck in slide cooperation way according to a normal structure. With a separated arrangement of the two connecting rod shaft necks, eccentric quality of the crankshaft is reduced and centrifugal force of the crankshaft is reduced but intensity of the crankshaft is remained unaffected; and by the use of the crankshaft connecting rod system on the warm forging press machine, overall rigidity of the press machine is enhanced, friction torque of the press machine is reduced and external size of a press machine clutch is decreased.
Description
Technical field
The utility model relates to press technologies field, and especially a kind of crankshaft connecting rod system of warm forging forcing press is made automated press line for the cold warm forging of multistation.
Background technology
Traditional press connecting rod method for designing is plain connecting rod, and the double link of two-point press is mounted on two bent axles or two eccentric gears.And warm forging automated press line requires the integral rigidity of forcing press very high, use double-crankshaft and two eccentric gear all cannot meet the rigidity requirement of cold warm forging.And use single axle, monotroded bar cannot solve the problem of forcing press unbalance loading.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, provide a kind of reasonable in design, simple in structure, operate steadily, can reduce forcing press friction torque, dwindle the crankshaft connecting rod system of the warm forging forcing press of press machine clutch volume.
The utility model solves the technical scheme that its technical problem adopts: a kind of crankshaft connecting rod system of warm forging forcing press, it comprises crankshaft-and-connecting-rod, described bent axle is comprised of trunnion and rod journal, it is characterized in that: described rod journal is comprised of first connecting rod axle journal and the second connecting rod axle journal of the identical diameter of axle, described first connecting rod axle journal and second connecting rod axle journal are respectively by default spacing, coaxially be eccentrically set on trunnion, described connecting rod is comprised of first connecting rod and second connecting rod, described first connecting rod, second connecting rod respectively routinely structure be slidably fitted in corresponding first connecting rod axle journal, on second connecting rod axle journal.
The utility model be on same bent axle by default spacing, coaxial eccentric setting two rod journals, connecting rod, two connecting rods respectively routinely structural correspondence be slidably fitted on two rod journals.Two rod journals divide the structure being arranged, and have alleviated the eccentric mass of bent axle, have reduced the centrifugal force of bent axle, and do not affect the intensity of bent axle.The utlity model has reasonable in designly, simple in structure, operate steadily, be applied to, on warm forging forcing press, can reduce the friction torque of forcing press, dwindle press machine clutch overall dimensions.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further.
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1. bent axle, 101. trunnions, 102. rod journals, 1021. first connecting rod axle journals, 1022. second connecting rod axle journals, 2. connecting rod, 201. first connecting rods, 202. first connecting rods.
The specific embodiment
As shown in Figure 1, a kind of crankshaft connecting rod system of warm forging forcing press, it comprises bent axle 1 and connecting rod 2.
In Fig. 1, bent axle 1 is comprised of trunnion 101 and rod journal 102.
Rod journal 102 is comprised of first connecting rod axle journal 1021 and the second connecting rod axle journal 1022 of the identical diameter of axle, and as shown in Figure 1, first connecting rod axle journal 1021 and second connecting rod axle journal 1022 are respectively by default spacing, be coaxially eccentrically set on trunnion 101.
Connecting rod 2 is comprised of first connecting rod 201 and second connecting rod 202, first connecting rod 201, second connecting rod 202 respectively routinely structure be slidably fitted on corresponding first connecting rod axle journal 1021, second connecting rod axle journal 1022.
The conventional structure that first connecting rod 201, second connecting rod 202 and first connecting rod axle journal 1021, second connecting rod axle journal 1022 are slidably matched is all: shaft and the connecting rod cap of connecting rod are connected as one by connecting-rod bolts, between tie rod holes seat and rod journal, connecting rod bearing shell are installed.
The utility model two rod journals divide and are arranged, and have alleviated the eccentric mass of bent axle, have reduced the centrifugal force of bent axle, and have not affected the intensity of bent axle.The utility model is applied to, on warm forging forcing press, improve the integral rigidity of forcing press, reduces the friction torque of forcing press, dwindles the overall dimensions of press machine clutch.
