Abstract
The utility model provides a fan drum flange punching device, which comprises a cantilever bracket, an ultrahigh pressure oil pump, a balancer, a puncher, a punching die, a flange die and a rotating platform, wherein the balancer is hung on the cantilever bracket; the puncher is mounted below the balancer in a hung manner; the punching die is vertically downwards mounted in an oil cavity of the puncher and is connected with the puncher at the tail end of a punch of the punching die through a restoring spring; a high pressure oil pipe of the ultrahigh pressure oil pump is vertically downwards introduced into the oil cavity of the puncher; the rotating platform is placed below the puncher and is used for placing a fan drum flange to be punched; and the flange die is fixedly mounted above the fan drum flange to be punched. Compared with the existing punching device, the fan drum flange punching device provided by the utility model has the advantages that a) the processing efficiency is improved by 3 times; b) the floor area is reduced by a half; c) the fan drum flange has no bur after being punched and follow-up polishing treatment is not needed; d) the requirement on operating personnel is lowered and the operating personal can be employed to operate the fan drum flange punching device after being simply trained; e) the labor intensity is greatly reduced; and f) the processing cost is low.
Description
Technical field
The utility model relates to a kind of air duct flange hole punched device, is mainly used in the punching processing of propeller fan air duct flange.
Background technology
Blower fan is one of most popular electromechanical equipment in the industrial production, and it generally is connected with miscellaneous equipment by flange.Along with the continuous progress of process technology and the requirement of cost efficiency, the air duct of propeller fan is improved to Flange by original welded flange, welded flange elder generation batch machining flange hole, then with the air duct welding, but the flange cost is higher and the welding job amount is large, production efficiency is low; Flange then needs first flange, then holes at Flange, and welding and processing cost are low.Use traditional rig-radial drill to add in the prior art to take up room man-hour greatly, labour intensity is high, efficient is low, subsequent handling is many, and equipment is expensive.Therefore, develop a kind of efficient drilling efficiency that reaches, can satisfy again the low-cost perforating press that requires, just become an urgent demand of propeller fan manufacturing enterprise.
Summary of the invention
The technical problem that solves
The problem that exists for solving prior art the utility model proposes a kind of air duct flange hole punched device.
Technical scheme
The technical solution of the utility model is:
Described a kind of air duct flange hole punched device is characterized in that: comprise pole bracket, superpressure oil pump, balancer, piercer, punch die, flange mould and rotation platform; Balancer is suspended on the pole bracket, and piercer hangs and is installed in the balancer below, and punch die is installed in the oil pocket of piercer straight down, and is connected by recovering spring with piercer at the drift tail end of punch die; The high-pressure oil pipe of superpressure oil pump passes into the oil pocket of piercer straight down; Rotation platform is placed on the piercer below, is used for placing the air duct flange for the treatment of punching; The flange mould is fixedly mounted on the air duct flange top for the treatment of punching.
Beneficial effect
The flange hole punched device that the utility model proposes, screw rod by the adjustment device, make piercer lifting and swing under null-gravity state, when stepping on the floor push of superpressure oil pump, the pressure of superpressure oil pump passes to piercer by high-pressure rubber pipe, piercer is started working, and the drift of punch die is moved down along the pilot hole of flange mould by the hydraulic oil effect, finishes punch operation.When unclamping floor push, drift is recovered spring action and is moved upwards up to initial position, prepares next punch operation.
The utility model is with respect to the advantage of existing drilling equipment: a) working (machining) efficiency improves 3 times; B) floor space is dwindled half; C) after the punching without burr, need not follow-up grinding process; D) operating personnel are required to reduce, get final product operation on duty through simple training; E) greatly reduced labour intensity; F) processing cost is low.
Description of drawings
Fig. 1 flange hole punched device structural representation;
Wherein: 1-pole bracket, 2-superpressure oil pump, 3-high-pressure rubber pipe, 4-floor push, 5-balancer, 6-piercer, 7-punch die, 8-flange mould, 9-clamp, 10-rotation platform.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described:
With reference to accompanying drawing 1, the air duct flange hole punched device in the present embodiment comprises pole bracket 1, superpressure oil pump 2, balancer 5, piercer 6, punch die 7, flange mould 8 and rotation platform 10.
Pole bracket 1 fixes on the ground, and balancer 5 is suspended on the pole bracket, and piercer 6 hangs and is installed in the balancer below, by adjusting balancer, piercer 6 is worked according to piercer weight under null-gravity state.Punch die 7 is installed in the oil pocket of piercer straight down, and is connected by recovering spring with piercer at the drift tail end of punch die.
Rotation platform 10 is placed on the piercer below, is used for placing the air duct flange for the treatment of punching; Flange mould 8 is fixedly mounted on the air duct flange top for the treatment of punching, by clamp 9 with flange mould 8 and the air duct flange clamping for the treatment of punching.
Selected punch die 7 designs according to different flange thicknesses and aperture with reference to the punch die handbook, guarantees that the hole is without the precision of burr and punching; Selected balancer 5 should be selected according to the weight of piercer 6, can work under null-gravity state to guarantee piercer 6, reduces labour intensity; The range of selected superpressure oil pump 2 and high-pressure rubber pipe 3 is determined according to the operating pressure of piercer 6.
By each parts of installation shown in Figure 1.First pole bracket 1 is fixed on the ground, balancer 5 is suspended on the pole bracket 1, piercer 6 is suspended on balancer 5 lower ends, connect by high-pressure rubber pipe 3 between superpressure oil pump 2 and the piercer 6, punch die 7 is installed on the piercer 6, use clamp 9 clampings between flange mould 8 and to be processed, to be processed is placed on the rotation platform 10.
During work, drag piercer 6 trim locations with hand, make the pilot hole of the drift alignment flange mould 8 of punch die 7, the floor push 4 that then tramps with one's feet is finished punch operation, unclamp floor push 4 after, the drift of punch die 7 is recovered spring action and is got back to initial position.
