Abstract

The utility model relates to a multipurpose plate bending machine for bending a metal plate with a thin wall, comprising a machine frame and an upper knife frame arranged on the machine frame. The both ends of the upper knife frame are connected with the both ends of the machine frame through positioning screws, and a limiting screw is arranged on the upper knife frame. A bearing is arranged in close vicinity to the lower side of the upper knife frame in the longitudinal direction in the both sides of the machine frame. When the positioning screws are loosened, the upper knife frame can move along the bearing. A lower basal frame is in movable connection with the machine frame and can vertically move in the machine frame. The utility model has simple structure and small size, is especially used for making an air pipe, can finish the overall process of making the air pipe, can make the air pipe with a small caliber one time and can bend a straight line.

Description

The multipurpose squeezer

The utility model relates to a kind of multipurpose squeezer, and belonging to metal blank does not have machining shaping operation machinery.

The squeezer that uses comprises that the upper tool post and that frame, is loaded in the frame is loaded on frame interior following pedestal and clamping driving apparatus at present.This class squeezer, its clamping mode mainly contain two kinds, and a kind of is that bevel type gear clamps, another kind is that eccentric wheel clamps, usually its size all needs to make quite greatly, can not finish the making of little airduct once, more impossiblely takes out case type workpiece easily.Because turnover panel is fixed on down on the pedestal, so can only be with workpiece bending to a fixed angle.

The purpose of this utility model provides a kind of multi-functional squeezer that is applicable to the bending of thin-wall metal sheet material, this squeezer can overcome the shortcoming that prior art exists, simple in structure, volume is little, is particularly useful for the making of ventilation shaft, can finish the overall process that ventilation shaft is made, and but once-forming ground makes small-bore airduct, also can do the straight line bending, as add and put other mould, can do the processing of box-like product.

A kind of multipurpose squeezer that the utility model provides, comprise frame, be loaded on upper tool post in the frame, be loaded on blade on the upper tool post, be loaded on down band handle on the pedestal turnover panel, be loaded on the following pedestal in the frame and be loaded on the interior clamping driving apparatus of frame, it is characterized in that: the upper tool post two ends are connected with set screw with the frame two ends, are provided with a limited screw between the upper tool post upper spider; Vertically nestle up the upper tool post below in the body of frame and be provided with bearing, upper tool post can move along bearing; Being connected between following pedestal and the frame is movable, and following pedestal can vertically move in frame.

Multi-functional squeezer according to the utility model provides is characterized in that: be provided with the downward countersunk head groove of twice on the appropriate location of 10 in following base; The angle of blade both sides is respectively 90 ° and obtuse angle; Be provided with a cover calutron in the following pedestal 10; Clamping driving apparatus is made up of jack, transmission bracket, height regulating rod; Frame is provided with power switch 16.

The multi-functional squeezer that the utility model provides compared with prior art, has following advantage: but once-forming ground makes small-bore airduct, and after finishing, can take out manufactured goods expediently; Because upper tool post does not remake and moves both vertically, and has dwindled the volume of squeezer, is convenient to mobile operating; Sheet material can be bent into the workpiece of 90 ° or other obtuse angle angle.

Below in conjunction with drawings and Examples, further specify characteristics of the present utility model, in the accompanying drawing:

Fig. 1 is the front view of multipurpose squeezer;

Fig. 2 is movable upper tool post schematic diagram;

Fig. 3 is a turnover panel double schematic diagram;

Fig. 4 is to countersunk head groove schematic diagram under the following pedestal

Fig. 1 is the front view of multipurpose squeezer of the present utility model.This multipurpose squeezer by the turnover panel 5 of frame 3, upper tool post 7, blade 9, band handle, down pedestal 10, transmission bracket 17, can regulate pole 18, jack 19 and foot-operated 20 is formed.Wherein upper tool post 7 is connected with set screw 1, set screw 12 with frame 3 both sides, and a limited screw 8 is arranged on the upper tool post 7, frame 3 both sides vertically in nestle up upper tool post 7 below a roller bearing 4 is arranged.As shown in Figure 2, after the making of finishing small-bore airduct 21, it is close-shaped that airduct has become, detachably descends set screw 12, and upper tool post 7 can promptly withdraw from along roller bearing 4 pullings.When upper tool post retreated to limited screw 8 places, small-bore airduct 21 can take out easily.The turnover panel 5 of band handle is connected with following pedestal 10 usefulness rotating shafts 13, and the axle core of rotating shaft 13 can be twitched, and turnover panel 5 can be installed on down pedestal 10 both sides as required, as shown in Figure 3.The angle of blade 9 both sides can be respectively 90 ° and obtuse angle; As in the present embodiment, the angle of blade 9 both sides, a side are 90 °, and opposite side is 150 °, make squeezer can process 90 ° or 150 ° of workpiece with interior various angles.Following pedestal 10 is loaded in the frame 3 movably, makes it vertically to move along frame.

As shown in Figure 4, in following appropriate location, pedestal 10 two ends, the size place that deducts the single twoport that needs folding with sheet material length is provided with down to the countersunk head groove, in the process of making airduct, be about to single upright mouthful 23, two upright mouthful 24 and place the countersunk head groove, not in the bending work that hinders sheet material.Clamping driving apparatus is made of transmission bracket 17, height regulating rod 18, jack 19, foot-operated 20.Jack 19 passes to down the power of a point by transmission bracket 17 on whole of pedestal.Jack 19 usefulness are ridden 20 liters of tops.Be provided with a cover calutron in the following pedestal 10,, promptly be provided with 6 solenoids 25 in the pedestal 10 down, behind the power-on switch 16, make solenoid 25 energisings produce electromagnetic attraction, can make down pedestal 10 clamping work pieces securely as in the present embodiment.Also be provided with power switch 16 on the frame.When needs loosen workpiece, only need disconnecting power switch 16, unclamp jack with riding 20, the then whole weight of pedestal 10 down descends it naturally, easily conversion work.
