Description

Technical Field

[0001] The utility model relates to the field of product processing equipment, in particular to an adjustable sheet metal bending machine. Background Art

[0002] Existing sheet metal parts can be bent using a bending machine, that is, a mechanical structure is used to apply force to the sheet metal parts to bend them into the required specific shape. Due to the structural limitations of the mechanical equipment, the parts of the existing bending machines used to place the sheet metal parts are generally fixed. In this way, when sheet metal parts with different bending degrees are required, other bending machines need to be used or tools such as pads need to be used to change the bending angle. The entire bending process will become more difficult due to the change in the bending angle. In addition, since the bending parts used in the existing bending machines apply an unchangeable pressure to the sheet metal parts during feeding, the effects produced when facing sheet metal parts of different thicknesses are different. For example, a thick sheet metal part may not be bent enough, and a thin sheet metal part may be overstressed at the bending point during the bending process, causing it to break.

[0003] Therefore, the existing sheet metal bending machines need to be further improved. Utility Model Content

Through the characteristic that the connecting rod can move back and forth linearly in the sleeve, the thread on the connecting rod is used for the sleeve to be inserted, and after the sleeve is inserted, the movable space of the sleeve can be limited by the positioning nut, and the movable space of the sleeve is between the outer end of the connecting rod and the nut, and the position of the sleeve can determine the length of the connecting rod extending from the inner side of the sleeve, thereby changing the distance between the upper ends of the two base plates.

[0024] The connecting rod 32 described in the utility model is hinged to the top of the base plate 21. After the connecting rod and the base plate are hinged, when the distance between the two connecting rods changes, the angle formed by the two base plates also changes.

[0025] The base support 1 in the utility model is provided with a top support 11, and the bending part 4 and the pressure regulating device 5 are provided on the top support 11. The top support is used to carry the bending part and the pressure regulating device.

The bottom of the bending pressure head 42 is an angle that can fit the substrate 21, and an air pipe 43 that can be connected to the air pressure device is arranged on one side of the cylinder 41. The cylinder is connected to the air pressure device through the outside of the air pipe. The cylinder can be extended and retracted by deflating or collecting air from the air pressure device, so that the bending pressure head can be pressed downward and retracted upward, so that the sheet metal part can be bent.

The working principle of the pressure regulating device is to narrow the air pipe to reduce the amount of air passing through the air pipe, so as to slow down the speed of the cylinder's expansion and contraction during this time period, thereby achieving the adjustment of the feed pressure. The specific adjustment steps are to adjust the thread depth of the locking screw on the vertical plate so that the locking screw presses the movable pressure block, and the movable pressure block moves toward the fixed pressure block until the notch of the movable pressure block narrows the air pipe. The fixed pressure block is fixed and the notch fits one side of the air pipe. When the movable pressure block approaches, the notches of the two can cooperate to compress the air pipe.
