Description

Technical Field

[0001] The utility model belongs to the technical field of bending machines, and in particular relates to a foldable front supporting device for a bending machine. Background Art

[0002] In the field of sheet metal processing, bending machines are usually used. In order to assist the sheet metal bending operation, a front support device is installed on the front vertical plate of the bending machine to assist in supporting the steel plate. At present, the front support of the bending machine is commonly used for sliding front supports with linear guides. That is, a horizontal linear guide is installed on the front vertical plate of the bending machine, and a support rack is installed on the slider. This kind of front support usually uses a tightening bolt to clamp the guide rail to fix it. After this kind of sliding front support is fixed, if there is a restriction on production or personnel movement, it is necessary to loosen the screws and remove the front support device. After the support is restored to its position, it needs to be locked again, which is more cumbersome to operate. In addition, this kind of sliding front support generally requires a parking space to be reserved on the outside of the front vertical plate of the bending machine, that is, the front support needs to be completely moved out of the length range of the front vertical plate to meet specific production needs. This results in the guide rail of the sliding front support being longer than the front vertical plate, which has a certain impact on the overall layout of the bending machine. Utility Model Content

[0003] The utility model aims to provide a foldable front support device for a bending machine to solve the problems existing in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foldable front support device of a bending machine, comprising a hinged seat, a first connecting rod, a second connecting rod, a third connecting rod and a support plate, one end of the first connecting rod and the second connecting rod are respectively hinged to the two ends of the hinged seat, the middle parts of the first connecting rod and the second connecting rod are hinged through a hinge shaft, the other end of the second connecting rod is hinged to the end of the support plate, the other end of the first connecting rod is hinged to one end of the third connecting rod, and the other end of the third connecting rod is hinged to the middle part of the support plate.

[0005] Preferably, the second connecting rod is longer than the first connecting rod.

[0006] Preferably, the cross section of the supporting plate is U-shaped.

[0007] Preferably, there are at least two sets of front supporting devices.

[0008] The beneficial effect of the utility model is that the device can conveniently realize the unfolding and folding of the support plate, and can also be installed on a linear guide rail to realize the avoidance function of the front support without moving the front support.

[0009] It can also be further designed to use two sets of front support mechanisms side by side, and connect the upper support plates together to form a workbench, realizing the function of a foldable work surface. It is suitable for some small bending machines. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0012] like Figure 1 As shown, a foldable front support device for a bending machine, an articulated seat 2 is installed on the front vertical plate 1 of the bending machine, and the fixing holes of the articulated seat 2 and the front vertical plate 1 of the bending machine are long holes, and the installation position of the articulated seat 2 on the front vertical plate 1 of the bending machine can be adjusted. The upper part of the articulated seat 2 is hinged to the first connecting rod 3. The middle part of the first connecting rod 3 is hinged to the second connecting rod 4, and the end of the first connecting rod 3 is hinged to the third connecting rod 5. The other ends of the second connecting rod 4 and the third connecting rod 5 are hinged to the support plate 6. The first connecting rod 3, the second connecting rod 4, the third connecting rod 5 and the support plate 6 form a four-bar mechanism. The pin shaft at the lower end of the second connecting rod 4 protrudes to both sides and is stuck in the holder at the lower part of the articulated seat 2. The holder at the lower end of the articulated seat 2 has an opening in the oblique upward direction, and the width of the opening is slightly larger than the pin shaft protruding from the lower end of the second connecting rod 4.

[0013] When folding the front support, the support plate 6 is moved upward, which will drive the pin shaft at the lower end of the second connecting rod 4 to move upward along the seat opening at the lower end of the hinge seat 2. When the pin shaft moves out of the opening, the support plate 6 can be slowly lowered downward. The connecting rods of the front support will be folded together, and at this time, the front support will be vertically attached to the front vertical plate 1 of the bending machine.

[0014] When the front support is unfolded, the support plate 6 is moved upward again, so that the pin at the lower end of the second connecting rod 4 is re-engaged in the opening of the holder at the lower end of the hinge seat 2. When the front support carries heavy objects, the pin at the lower end of the second connecting rod 4 is pressed against the holder at the lower end of the hinge seat 2 by force, thereby ensuring the safety of the mechanism.

[0015] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
