A kind of sheet metal bar folder for construction site, is related to technical field of building construction, and the solution is to bend sheet metal at the construction field (site).The bar folder includes bottom plate, upper mold；The top surface left part of the bottom plate is fixed with a hinged-support, and the top surface right part of bottom plate is fixed with a lever bracket, and the top surface of bottom plate sets that there are two the lower dies that can be slid back and forth；There is a lever, the left end of the lever and hinged-support are pivotally connected, and the right part of lever is shelved on lever bracket on the hinged-support；Described two lower dies are placed in the front and rear sides of upper mold, and the top surface of bottom plate is fixed with multiple adjusting supports, each to adjust on support equipped with the adjusting bolt for fixing two lower dies；The upper mold is the triangular support body of an apex angle upward, and between hinged-support and lever bracket, the top corner part of upper mold is pivotally connected in a manner of being freely rotated with lever upper mold.Bar folder provided by the invention, the sheet metal suitable for construction site are bent.
Description
Technical field
The present invention relates to building construction technologies, more particularly to a kind of skill of sheet metal bar folder for construction site
Art.
Background technique
Construction site often involves a need to the problem of reusing after bending sheet metal.Currently, common sheet metal is curved
It rolls over there are two types of solutions:
The first scheme is to transport construction site to again after sheet metal is bent to set angle by factory in advance, but bend
Steel plate transport afterwards is inconvenient, and needs to occupy biggish space, can not adapt to the actual size variation of construction site；
Second scheme be carry out at the construction field (site) it is hand-made, but currently without corresponding sheet metal bending device,
Sheet metal can only be bent by artificial hammering way, with the low defect of large labor intensity, operating efficiency, and bend quality
Unstable, the bending angle error of sheet metal is larger.
Summary of the invention
For above-mentioned defect existing in the prior art, can be reduced technical problem to be solved by the invention is to provide a kind of
Labor intensity improves operating efficiency and operation quality, adapt to the actual size variation of construction site for construction site
Sheet metal bar folder.
In order to solve the above-mentioned technical problem, a kind of sheet metal bar folder for construction site provided by the present invention,
It is characterized in that: including bottom plate, upper mold；
The top surface left part of the bottom plate is fixed with a hinged-support, and the top surface right part of bottom plate is fixed with a lever bracket；
Have one pivotable lever, the left end of the lever and hinged-support can be pivotally connected up and down on the hinged-support, the right side of lever
Portion is shelved on lever bracket, and is fixed with one handle in the right end of lever；
The top surface of the bottom plate is set there are two the lower die that can slide back and forth, which is placed in the front and back two of upper mold
Side, the top surface of bottom plate is fixed with multiple adjusting supports, each to adjust on support equipped with the adjusting bolt for fixing two lower dies；
The upper mold is the triangular support body of an apex angle upward, and upper mold is between hinged-support and lever bracket, the top of upper mold
Corner is pivotally connected in a manner of being freely rotated with lever, and its pivot axis is parallel to the pivot axis of lever, the base vertical of upper mold
In the pivot axis of lever.
Further, the flat hole of a bar shaped is offered on the lever, the pivot of upper mold top corner part is arranged in the flat hole of the bar shaped
In.
Lever is applied smaller outer provided by the present invention for the sheet metal bar folder of construction site using lever principle
Power can easily realize steel plate bending under the cooperation of upper die and lower die, by adjusting the spacing between two lower dies, can adjust steel
The bending angle of plate, thus the actual size variation of construction site is also adapted to, the sheet metal especially suitable for construction site is curved
Folding.
Detailed description of the invention
Fig. 1 is the perspective view of the sheet metal bar folder for construction site of the embodiment of the present invention；
Fig. 2 is the main view of the sheet metal bar folder for construction site of the embodiment of the present invention；
Fig. 3 is the top view of the sheet metal bar folder for construction site of the embodiment of the present invention.
Specific embodiment
The embodiment of the present invention is described in further detail below in conjunction with Detailed description of the invention, but the present embodiment is not used to limit
The system present invention, it is all using similar structure and its similar variation of the invention, protection scope of the present invention should all be included in.
As shown in Figure 1-Figure 3, a kind of sheet metal bar folder for construction site provided by the embodiment of the present invention, it is special
Sign is: including bottom plate 2, upper mold 6；
The top surface left part of the bottom plate 2 is fixed with a hinged-support 3, and the top surface right part of bottom plate is fixed with a lever bracket 4, bottom plate
2 bottom surface quadrangle is respectively fixed with a support leg 9；
Have one pivotable lever 1, the left end of the lever 1 and hinged-support 3 can be pivotally connected up and down on the hinged-support 3, lever 1
Right part be shelved on lever bracket 4, and be fixed with one handle 10 in the right end of lever 1；
The top surface of the bottom plate 2 is set there are two the lower die 5 that can slide back and forth, which is placed in the front and back of upper mold 6
Two sides, the top surface of bottom plate 2 is fixed with multiple adjusting supports 7, each to adjust on support 7 equipped with the tune for fixing two lower dies 5
Save bolt 8；
The upper mold 6 is the triangular support body of an apex angle upward, and upper mold 6 is between hinged-support 3 and lever bracket 4, upper mold 6
Top corner part be pivotally connected in a manner of being freely rotated with lever 1, and its pivot axis is parallel to the pivot axis of lever 1, the bottom of upper mold 6
While perpendicular to the pivot axis of lever 1.
In the embodiment of the present invention, the left part of lever 1 is arranged in the upper mold 6, and it is flat to offer a bar shaped on the lever 1
The pivot in hole, 6 top corner part of upper mold is arranged in the flat hole of the bar shaped.
The usage mode of the embodiment of the present invention is as follows:
First according to steel plate the to be bent angle to be bent, two lower dies are adjusted using the adjusting bolt 8 adjusted on support 7
Spacing between 5 to appropriate spacing, and make the spacing between two lower dies 5 and upper mold 6 it is identical (i.e. upper mold be located at two lower dies it
Between center), then lever 1 is pivoted up to the bottom edge of upper mold 6 and is higher than two lower dies 5, then steel plate to be bent set
On two lower dies 5, and it is aligned the folding line of steel plate to be bent and the bottom edge of upper mold 6, then presses handle 10 still further below,
So that lever 1 pivots downwards, upper mold 6 also applies uniformly distributed line pressure to the steel plate in two lower dies 5 by its bottom edge immediately, makes steel
Plate is bent to specified angle.
