Description

Technical Field

[0001] The utility model relates to the field of stamping, and more specifically, to a high-efficiency stamping device with adjustable hardware bending angle. Background Art

[0002] In the metal stamping and bending process, first of all, it is necessary to make suitable punching dies and bending dies according to the design requirements and install them on the punch press. Then, the metal sheet is placed on the workbench of the punch press and clamped by a clamp to keep it stable. Next, the punch impacts the metal sheet by applying pressure to cut out the required outer contour shape. At the same time, the punch can also perform a perforation operation through the internal hole die. After the impact operation is completed, the bending equipment on the punch press will bend the metal sheet.

[0003] In the above process, since the punching die and the bending die are fixed one at the top and the other at the bottom, if the bending angle needs to be adjusted, the punching die and the bending die must be removed and replaced at the same time, and the structure of the punching die and the bending die needs to be redesigned. There is no doubt that such a process will not only increase a lot of costs, but also delay the construction period.

[0004] To this end, a high-efficiency hardware stamping device with adjustable bending angle is proposed to solve some problems existing in the above-mentioned prior art. Utility Model Content

[0005] 1. Technical problem to be solved: How to change the bending angle by using the original punching die and bending die without redesigning the punching die and bending die.

[0006] 2. Technical solution: A high-efficiency hardware stamping device with adjustable bending angle, including a lower component and an upper component, the lower component including a base plate, the top of the base plate is symmetrically connected to two connecting plates, the top of the connecting plate is installed with a bracket and a lifting component symmetrical about the bracket, the upper component includes a horizontal plate installed on the top of the lifting component, which is symmetrical about the bracket and perpendicular to it, the inner sides of the horizontal plate and the bracket are connected to metal columns, a columnar die is arranged between one group of left-right symmetrical metal columns, a columnar bending die is arranged between the two metal columns, clamping components are arranged between the metal columns, the columnar bending die and the columnar die, and an adjustment component is arranged on the base plate.

[0007] 3. Beneficial effects

[0008] Compared with the prior art, the advantages of the present invention are:

[0009] (1) The utility model can adjust the distance between one connecting plate and the other connecting plate under the action of the adjustment component. At this time, the distance between the metal column on the connecting plate and the metal column on the other connecting plate can be changed. Under this condition, because the column bending die and the column punching die are both engaged by the engaging component arranged between the left and right metal columns, the column bending die and the column punching die can be removed after the distance between the left and right metal columns is changed. In this way, when it is necessary to change the bending angle, it is only necessary to replace the column bending die of different diameters, and the column punching die only needs to adaptively adjust and replace the distance between the column bending dies through multiple evenly distributed metal columns on the cross plate.

[0010] (2) The utility model sets two cylindrical punching dies front and back below the cylindrical bending die. The two cylindrical punching dies not only provide a punching effect, but also play a supporting effect on the plate, so there is no need for an additional clamp structure to clamp the plate to be bent.

The upper component includes a horizontal plate 5 installed at the top of the lifting component 4, which is symmetrical about the bracket 3 and perpendicular to it, and the inner sides of the horizontal plate 5 and the bracket 3 are connected to metal columns 6. On the one hand, there are multiple metal columns 6 on the horizontal plate 5, and they are evenly distributed along the length direction. Among these metal columns 6, a columnar die 8 is set between one group of metal columns 6 that are symmetrical on the left and right. On the other hand, there is one metal column 6 on the bracket 3, and a columnar bending die 7 is set between the two metal columns 6. A clamping component 9 is set between the metal column 6, the columnar bending die 7 and the columnar die 8.

[0021] See also Figure 3 and Figure 4 The snap-fit ​​assembly 9 includes rectangular grooves 901 opened at both ends of the cylindrical bending die 7 and the cylindrical punching die 8, and the inner side of each metal column 6 is connected to a rectangular block 902 adapted to the rectangular groove 901. An adjustment assembly 10 for adjusting the horizontal distance between one connecting plate 2 and another connecting plate 2 is provided on the bottom plate 1.

[0022] See also Figure 3The adjustment assembly 10 includes an upper hole 1001 through which one of the connecting plates 2 is opened, and two rows of lower holes 1002 are opened on the bottom plate 1, which are adapted to the upper holes 1001 and have different distances from the other connecting plate 2. The connecting plate 2 and the bottom plate 1 are connected by connecting bolts 1003 through the upper holes 1001 and the lower holes 1002. The bolts 1003 are composed of a head and a bolt body. A metal or rubber gasket located between the head and the connecting plate 2 can be sleeved on the outer peripheral side of the bolt body to prevent slipping. Under the initial condition, the corresponding A connecting plate 2 is fixed by bolts 1003 in a lower hole 1002 close to another connecting plate 2. The distance between the metal columns 6 on both sides is just enough to clamp the column bending die 7 and the column punching die 8 through the clamping assembly 9. When the connecting plate 2 is fixed in the lower hole 1002 away from the other connecting plate 2, the clamping assembly 9 is separated. In this way, the column bending die 7 is replaced with structures of different diameters, and the column punching die 8 is adjusted on the cross plate 5 to adapt to different diameters. The bending angle can be changed by only replacing the column bending die 7.
