Background
When the stroke of the existing press machine is designed, an integral type eccentric sleeve structure is usually adopted, and due to the fact that the eccentric sleeve is integral, when the stroke of the existing press machine is large in demand, the size of the eccentric sleeve needs to be correspondingly enlarged, the size of an eccentric part and the size of a mechanism at the large end of a connecting rod are enlarged, the size of the whole press machine is large, and the economical efficiency and the attractiveness of the whole press machine are affected. In addition, the eccentric diameter is enlarged, so that the friction torque is increased, and the product processing is influenced, therefore, the existing eccentric structure of the press machine cannot adapt to the requirements of larger and larger press machine stroke.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in view of the above problems, the present invention provides an eccentric structure of a large stroke press, which makes the structure more compact and improves the working stability of the whole press.
The technical scheme is as follows: the utility model provides a large-stroke press eccentric structure, includes dabber, gland, rotator, connecting axle, the dabber is equipped with two, and coaxial symmetry interval sets up, two the end that departs mutually of dabber is respectively through one the gland is connected with the fuselage of press, the looks remote site respectively with one the rotator is connected, makes two the rotator symmetry interval sets up, the connecting axle sets up in two between the rotator, its both ends are worn to locate two respectively in the rotator and fixed, the axis of connecting axle with eccentric volume A has between the axis of dabber, the link assembly cover of press is located on the connecting axle and rather than being connected.
The eccentric sleeve is eliminated, the rotating body is additionally provided with the connecting shaft to form the processing eccentric amount of the press, the two mandrels are arranged to form a sectional mandrel structure, the processing is simple, the structure cost is lower, the eccentric amount is the distance between the central axis of the connecting shaft and the central axis of the mandrels, the eccentric amount can be set according to the diameter size of the connecting shaft and the installation position on the rotating body according to the requirements of customers, and the operation is convenient and fast; the original connecting rod assembly of the press is arranged on the connecting shaft, and the connecting rod on the connecting rod assembly moves up and down under the driving of the connecting shaft, so that the purpose of large stroke required by customers is achieved.
Furthermore, dabber one end wear to locate in the fuselage, the gland with the terminal surface laminating of dabber and with the fuselage overlap joint, the fuselage, the dabber respectively through the screw with the gland is connected.
Furthermore, the rotator is the gear, the middle part of rotator is worn to locate the one end of dabber, the rotator pass through the key with the dabber is connected.
Further, the connecting shaft is a crankshaft.
Preferably, the connecting shaft is a straight-column crankshaft.
Has the advantages that: compared with the prior art, the utility model has the advantages that: the eccentric sleeve is eliminated, the eccentric amount of the press machine is formed by additionally arranging the connecting shaft on the rotating body, the structural size is optimized, the eccentric sleeve structure which is difficult to process and guarantee is eliminated, the structural layout of a transmission part is simplified, and the structural size of the whole press machine equipment is optimized; a sectional mandrel structure is adopted, so that the processing is simple and easy, and the structural cost is lower; the structural size of the core part and the big end of the connecting rod is correspondingly reduced, and the friction torque is reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further elucidated with reference to the drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention.
An eccentric structure of a large-stroke press is shown in figure 1 and comprises a mandrel 1, a gland 2, a rotating body 3 and a connecting shaft 4, wherein the rotating body 3 is a gear, and the connecting shaft 4 is a straight-column type crankshaft.
Dabber 1 is equipped with two, coaxial symmetry interval sets up and is a straight line, the fuselage 5 of press is worn to locate respectively by the end of separating mutually of two dabbers 1, every dabber 1 all is connected with fuselage 5 through a gland 2, gland 2 and dabber 1's terminal surface laminating and with 5 overlap joints of fuselage, fuselage 5, dabber 1 is connected with gland 2 through the screw respectively, two dabber 1's looks remote site respectively with a rotator 3 connection, the one end of dabber 1 is worn to locate at the middle part of rotator 3, rotator 3 is connected with 1 outer peripheral face of dabber through the key.
Two 3 symmetry intervals of rotator set up, and connecting axle 4 sets up between two rotators 3, and its both ends wear to locate in two rotators 3 respectively and fix, and connecting axle 4 is parallel with dabber 1, has eccentric volume A between the axis of connecting axle 4 and the axis of dabber 1, and connecting axle 4 is located to the link assembly 6 cover of press and is connected with it.
This eccentric structure cancellation eccentric bushing, add the processing eccentric volume of establishing the connecting axle and forming the press through the rotator, set up two dabbers, form sectional type dabber structure, processing is simple and easy, and structure cost is lower, has reduced the processing manufacturing cost and the processing degree of difficulty, very big retrench eccentric structure, the eccentric volume is the interval between the axis of connecting axle and dabber promptly, can set up the eccentric volume through the diameter size that sets up the connecting axle and the mounted position on the rotator according to the customer demand, convenient and fast.
The original connecting rod assembly of the press is arranged on the connecting shaft, and the connecting rod on the connecting rod assembly moves up and down under the driving of the connecting shaft, so that the aim of large stroke required by a customer is fulfilled; the straight-column crankshaft is adopted, no crank throw is arranged, the processing difficulty is reduced, the structural sizes of the eccentric part and the big end of the connecting rod are correspondingly reduced, and the friction torque is reduced accordingly.
