Abstract
The invention discloses a supporting device used for pressing the large-scale screw. The supporting device comprises a lead screw, a driving mechanism of the lead screw, a fixing nut arranged on the lead screw and a fixing support used for supporting the driving mechanism, wherein the top of the lead screw supports the large-scale screw; and the driving mechanism is connected with the lower end of the lead screw. The supporting device adopts a screw pair composed of the lead screw and the fixing nut, the lead screw is driven by the driving mechanism and the lead screw rotates while performing axial movement, thus the aim of adjusting the height of the top of the lead screw can be achieved. Therefore, the central hole on the lower cross beam of the hydraulic press can hold different lengths of large-scale screws, the hydraulic press can use one mould to prepare different lengths of large-scale screws, the number of replacements of the production mould can be reduced and the production efficiency of the hydraulic press for pressing the large-scale screw can be increased.
Description
Technical field
The present invention relates to a kind of bracing or strutting arrangement, particularly a kind of bracing or strutting arrangement that is used to suppress large-scale screw.
Background technology
Along with world energy sources is advocated low-carbon (LC), various novel energy forms also constantly develop and reform, wherein the development of wind-power electricity generation dazzling nova in the green energy resource especially.In wind power plant, the type of attachment of wind turbine and generator is the bottleneck of puzzlement wind-power electricity generation development always, and along with the use of high-strength screw, wind-power electricity generation is progressively gone on new level.
In today of wind-power electricity generation fast development, the large-scale production that improves each parts is very important, and this will guarantee the raising of whole wind-driven generator production efficiency, the reduction of production cost.At present, the large-scale screw that is used for wind-driven generator normally behind the open die forging again by machined remove surface scale, machining screw forms.There is following problem in said method: 1) metal structure of part changes needs the time longer; 2) need to reserve bigger allowance, material consumption is more; 3) part precision is poor; 4) production efficiency is lower.Free forging process is for the screw that uses in the general operating mode, and is still applicable, but for high-strength screw, just can't satisfy batch production requirement.In order to address the above problem, produced the large-scale screw technology of hot pressing multi-ram forging, realized the hot pressing multi-ram forging of large-scale screw, but the large-scale screw of different length need be changed different production moulds, operation is very complicated, and operating efficiency is very low.
Summary of the invention
The present invention provides a kind of bracing or strutting arrangement that is used to suppress large-scale screw for solving the technical problem that exists in the known technology, uses the hydraulic press of this device need not change the compacting that production mould just can be finished the large-scale screw of different length.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of bracing or strutting arrangement that is used to suppress large-scale screw, comprise the described large-scale screw of apical support leading screw and driving mechanism thereof, be installed in the Fixed Nut on the leading screw and support the fixed support of described driving mechanism, described driving mechanism is connected the lower end of described leading screw.
The present invention can also adopt following technical scheme: described driving mechanism comprises transmission mechanism and drive motors thereof; Described transmission mechanism comprise the worm screw that is connected with drive motors and with the worm gear of described worm engaging, the lower end of described worm gear is connected with guide pin bushing, the described guide pin bushing upper edge direction parallel with described leading screw offers the twice guide groove, be provided with in the per pass guide groove one with the affixed guide pad in lower end of described leading screw.
Advantage and good effect that the present invention has are: adopt the screw pair of being made up of leading screw and Fixed Nut, use the drive mechanism leading screw, double axially moving when leading screw rotates, thereby reach the purpose of regulating leading screw top height, make accommodation hole on the hydraulic press sill can hold the large-scale screw of different length, hydraulic press uses same mould just can make the large-scale screw of different length, has reduced the replacing number of times of production mould, has improved the production efficiency that hydraulic press is suppressed large-scale screw.

Among the figure: 1, punch, 2, right half die, 3, sill, 4, leading screw, 5, left half die, 6, large-scale screw, 7, feed inlet and outlet, 8, Fixed Nut, 9, worm gear, 10, protective cover, 11, guide pin bushing, 11-1,11-2, guide groove, 12, guide pad, 13, worm screw, 14, drive motors, 15, fixed mount.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, now exemplify following examples, and conjunction with figs. is described in detail as follows: see also Fig. 1～Fig. 2, use forging mold and make the course of work of large-scale screw: large-scale screw 6 is before compacting, heat its bar-shaped stock upper end, bar-shaped stock after the heating is put into accommodation hole on the hydraulic press sill from the feed inlet and outlet 7 on the hydraulic press sill 3, and bar-shaped stock is vertical with sill 3, and its lower end is supported by leading screw 4.Bar upper end after the heating has the good metal flowability, and left and right sides two halves die 5,2 under the driving of clamping and positioning oil cylinder, carries out matched moulds respectively, and the lower cavity die of two halves combination clamps the bar-shaped stock of screw.Punch 1 is installed on the slide block of hydraulic press, and the slide block of hydraulic press drives the upper end of 1 pair of bar-shaped stock of screw of punch and pushes, and mould overcomes owing to the branch mould power that expansion of metal brought, and the head of screw after the assurance compression moulding reaches the shape of regulation.
Present embodiment is a kind of bracing or strutting arrangement of suppressing large-scale screw, this bracing or strutting arrangement comprises above-mentioned leading screw 4 and driving mechanism and the Fixed Nut 8 that is installed on the leading screw 4, the large-scale screw 6 of the apical support of leading screw 4, be connected with driving mechanism and Fixed Nut 8 on the leading screw 4, driving mechanism is connected the lower end of leading screw 4.Driving mechanism comprises transmission mechanism and the drive motors 14 thereof that is connected with leading screw 4, and transmission mechanism and drive motors 14 thereof are installed on the fixed mount 15.In order to make compact conformation, stable drive, in the present embodiment, transmission mechanism comprises worm screw 13 that is connected with drive motors 14 and the worm gear 9 that meshes with worm screw 13, the lower end of worm gear 9 is connected with guide pin bushing 11, guide pin bushing 11 upper edges and leading screw 4 parallel directions offer twice guide groove 11-1,11-2, are provided with a guide pad 12 that is fixed in leading screw 4 lower ends in the per pass guide groove.
In order to guarantee transmission safety, above-mentioned worm screw 13 and worm gear 9 are installed in the protective cover 10, and protective cover 10 is fixed on the fixed mount 15.
