Problems solved by technology

The supporting device adopted in this application is still greatly affected by the length of the plate to be processed. When the length of the plate is short, the supporting device cannot be used to support the material, so that the processing accuracy cannot be guaranteed. There is a large gap between the plates, which causes the sheet material generated by shearing to be easily inserted into the above gap, and needs to be manually removed, which is troublesome to operate

Embodiment 1

[0046] combine Figure 1-Figure 4 , a four-point pneumatic supporting device for a plate shearing machine in this embodiment includes a supporting frame 5, a supporting rod 7 and a supporting frame 8, wherein one end of the supporting rod 7 and the supporting frame 8 is connected to the supporting frame 5 Hinged, the other ends of the support rod 7 and the support frame 8 are hinged with the workbench 1, and the swing of the support rod 7 and the support frame 8 drives the support frame 5 to swing up and down, thereby realizing the support and unloading of the sheet material 3 to be processed. material. The material supporting device of this embodiment can set the length of the material supporting frame 5 according to the distance between the rear baffle and the workbench, so that the material supporting distance between the material supporting frame 5 and the blade can be effectively reduced to 8- 12mm, compared with the existing supporting device, the supporting gap is grea...

Embodiment 2

[0048] combine Figure 1-Figure 4 , a four-point pneumatic material support device for a shearing machine in this embodiment, its structure is basically the same as in Embodiment 1, the difference is that: the back of the workbench 1 is equipped with a transmission shaft 11 through a bracket, and the transmission shaft 11 is connected to the The driving device is connected, and one end of the support frame 8 is fixedly connected with the transmission shaft 11 . The driving device drives the transmission shaft 11 to rotate, thereby driving the support frame 8 to rotate, and under the joint action of the support frame 8 and the support rod 7, the support frame 5 is driven to swing up and down. Through the function of the transmission shaft 11, the entire material supporting device can be driven to perform synchronous movement, thereby ensuring the shearing accuracy of the plate and reducing errors.

[0049] The above-mentioned support frame 8 and support rod 7 are the key compo...

Embodiment 3

[0052] combine Figure 1-Figure 4 , a four-point pneumatic material support device for a shearing machine of this embodiment, its structure is basically the same as that of Embodiment 2, the difference is that the driving device of this embodiment includes a swing rod 12 and a cylinder 13, wherein one end of the swing rod 12 It is fixedly connected with the transmission shaft 11 , and its other end is hinged with the piston rod of the cylinder 13 , and the cylinder body of the cylinder 13 is hinged to the workbench 1 through the cylinder bracket 15 . The telescopic drive of the piston rod of the cylinder 13 drives the swing rod 12 to rotate, thereby driving the transmission shaft 11 to rotate, and further driving the support frame 5 to swing up and down.

[0053] In this embodiment, the distance between point A and the end of the support frame 5 near the workbench 1 is 1 / 3 of the total length of the support frame 5, and the distance between point B and the end of the support f...

Abstract

The invention discloses a four-point pneumatic supporting device and method for a plate shearing machine and belongs to the technical field of plate shearing machines. The four-point pneumatic supporting device for the plate shearing machine comprises a supporting frame, a support rod and a support frame. One end of the support rod and one end of the support frame are both hinged to the supportingframe. The other end of the support rod and the other end of the support frame are both hinged to a workbench. The support rod and the support frame swing to drive the supporting frame to swing up and down so as to achieve supporting and discharging of plates to be processed. The four-point pneumatic supporting device is used for supporting the plates to be processed, and a gap between the supporting plate and the workbench can be reduced effectively, so that the use requirements of the to-be-sheared plates with different lengths are met, and accordingly the shearing quality and accuracy of the plates can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of shearing machines, and more specifically relates to a four-point pneumatic material supporting device and method for shearing machines. Background technique [0002] In the machinery manufacturing industry, the shearing machine is a commonly used processing equipment. It is mainly used for shearing and blanking of plate workpieces. It has the characteristics of easy operation and high work efficiency. The shearing machine has been widely used in general machinery manufacturing, automobile , container manufacturing, switching electrical appliances and light industry industries such as cutting parts processing. Although there are many types of shearing machines currently in use, they are basically similar in terms of working principles and structural types. Generally, the lower tool rest is fixed, and the workpiece to be processed is sent to the upper blade and the lower blade by the shearing machine workbe...
