Abstract
The utility model relates to a crankshaft bearing mechanism of a pressing machine, which relates to a crankshaft front-back bearing mechanism of the pressing machine, a punching machine and other processing machinery; the utility model is one part of the pressing machine, the punching machine and other processing machinery, and belongs to technology field of processing machinery; the utility model is the improvement to the crankshaft bearing mechanism of the existing pressing machine, and the characteristics are as follows: the original copper sleeve bearing of the crankshaft front-back supporting necks is changed into the co-bearing of the copper sleeve and the bearing, in this way, the rigid bearing of the bearing is provided, therefore, the utility model facilitates not only increasing the rigidity of the copper sleeve, but also increasing the service life of the copper sleeve, and increasing the machining precision during the blanking of the pressing machine, and reducing the maintenance cost and the using cost; the utility model has simple structure, good practicability, and facilitates increasing the product quality for manufacturing enterprises, and is suitable for the pressing machine, the punching machine and other blanking processing machinery.
Description
Technical field
The utility model relates to crankshaft support mechanism in a kind of forcing press, relates to the bent axle front and back supporting device of processing equipments such as forcing press, punch press, is the some in the stamping-out processing equipments such as forcing press, punch press, belongs to the processing equipment technical field.
Background technology
The preceding supporting neck of two supporting necks is by the copper sheathing supporting in preceding supporting and the preceding supporting before and after the bent axle in the processing equipments such as existing forcing press, punch press, back supporting neck is by the corresponding vestibule and the supporting of the copper sheathing in the vestibule of fuselage, this main main deficiency that is existed by the crankshaft support mechanism of copper sheathing structure is, the rotation of the high speed of press crankshaft and repeatedly during stamping-out the rigidity of copper sheathing obviously not enough, since the wearing and tearing of copper sheathing, the precision in the time of can not guaranteeing forcing press, punch press stamping-out fully.
Summary of the invention
The purpose of this utility model provides crankshaft support mechanism in a kind of forcing press, solve existing press crankshaft supporting device because of reasons in structure, the rigidity deficiency of copper sheathing when having the forcing press stamping-out, and can not guarantee the deficiency of the precision of forcing press stamping-out fully, realize helping improving the rigidity and the service life of copper sheathing by the utility model, thus the machining accuracy when helping improving forcing press, punch press stamping-out.
The purpose of this utility model is achieved through the following technical solutions, and crankshaft support mechanism comprises bent axle in a kind of forcing press, supporting neck is nested with before the bent axle preceding supporting and preceding copper sheathing, the preceding gland that the front end face of crankshaft front end face fixed end caps, preceding supporting is fixing; The back copper sheathing that supporting neck is nested with behind the bent axle, rear pressing cover is characterized in that, the copper sheathing outer end of supporting neck is nested with bearing before and after the bent axle.
Between the bearing top circle face that supporting neck is nested with before the described bent axle and the respective face of preceding supporting sealing ring is set.
In the rear pressing cover of the bearing outer face that supporting neck is nested with behind the described bent axle oil sealing is set.
The utility model is the improvement to existing press crankshaft supporting device structure, main feature is to only depend on the copper sheathing supporting to change copper sheathing into to add bearing and support jointly with supporting neck before and after the bent axle is former, like this, owing to had the non-yielding prop of bearing, both helped improving the rigidity of copper sheathing, help improving the service life of copper sheathing again, machining accuracy when helping improving the forcing press stamping-out, maintenance cost and use cost have been reduced, the utility model is simple in structure, have very strong practicality, help the quality that product improves in manufacturing enterprise, the utility model is applicable to forcing press, stamping-out processing equipments such as punch press.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure, 1 preceding gland, 2 end caps, 3 bearings, 4 sealing rings, 5 preceding copper sheathings, 6 preceding supportings, 7 bent axles, 8 back copper sheathings, 9 bearings, 10 rear pressing covers, 11 oil sealings.
The specific embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the utility model comprises bent axle 7, supporting neck is nested with before the bent axle 7 preceding supporting 6, preceding copper sheathing 5 and bearing 3, the preceding gland 1 that the front end face of bent axle 7 front end face fixed end caps 2, preceding supporting 6 is fixing; Back copper sheathing 8 that supporting neck is nested with behind the bent axle and bearing 9; Bearing 3,9 is nested with copper sheathing 5,8 outer ends at bent axle 7 front and back supporting necks respectively. and be provided with between bearing 3 peripheries that supporting neck is nested with before the bent axle 7 and the respective face of preceding supporting 6 in the rear pressing cover 10 of bearing 9 outer faces that sealing ring 4. bent axles 7 back supporting necks are nested with oil sealing 11. is set
Claims (3)
