Description

Technical Field

[0001] The utility model relates to the field of fixtures for cutting aluminum alloy bars, and specifically to a tooling fixture suitable for automatic cutting of aluminum alloy bars by a bench band saw / wire saw. Background Art

[0002] With the development of aluminum alloy forging, the quality requirements for the extruded bar blank materials in aluminum alloy forging are getting higher and higher. The tensile property requirement of the extruded bar blank material is one of the important quality indicators. In the industry, it is necessary to cut the bar into 4 samples by centering, and make test bars from the center of 1 / 4 of the bar. However, it is very difficult to divide the bar along the extrusion straightening direction with the existing ordinary bench band saws and wire saws on the market. Not only can the flatness of the cutting section after cutting not be guaranteed, but also manual operation is prone to dangers such as mechanical injury and flying materials. Summary of the Utility Model

[0003] The utility model provides a tooling fixture suitable for automatic cutting of aluminum alloy bars by a bench band saw / wire saw, so as to solve the problem of danger caused by manual operation when the existing ordinary bench band saws and wire saws cut aluminum alloy bars.

[0004] In order to achieve the above object, the technical solution adopted by the utility model is as follows:

[0005] A tooling fixture suitable for automatic cutting of aluminum alloy bars by a bench band saw / wire saw, including the workbench of the bench band saw / wire saw, in which a cutting saw is vertically and penetratingly installed. It is characterized in that a blank holder is horizontally and linearly movably installed on the top surface of the workbench, and the aluminum alloy bar to be cut is axially and horizontally fixed in the blank holder, and a part of the aluminum alloy bar to be cut protrudes from the blank holder; a horizontal linear motion driving mechanism is installed on the top surface of the workbench, and the blank holder is driven by the horizontal linear motion driving mechanism to move horizontally in a straight line, so as to drive the aluminum alloy bar to be cut to move horizontally in a straight line through the blank holder; the cutting saw is located on the horizontal linear motion path of the part of the aluminum alloy bar to be cut that protrudes from the blank holder.

[0006] Further, a trolley is provided on the top surface of the workbench. The bottom of the trolley has a slider, and a guide groove is also provided on the top surface of the workbench. The slider at the bottom of the trolley is slidably installed in the guide groove, and the wheels of the trolley are in contact with the top surface of the workbench. The blank holder is fixed on the top of the trolley, and the horizontal linear motion driving mechanism drives the trolley and the blank holder to move horizontally in a straight line as a whole.

[0007] Further, the horizontal linear motion driving mechanism is a lead screw slider mechanism, and the slider in the lead screw slider mechanism is fixedly connected to the blank holder or the trolley.

[0008] Furthermore, the blank holder is a horizontally placed U-shaped frame. The aluminum alloy bar to be cut is axially and horizontally placed in the U-shaped opening of the blank holder, and a part of the aluminum alloy bar to be cut protrudes from the U-shaped opening of the blank holder.

[0009] Furthermore, a threaded through hole is provided on one U-shaped wall of the blank holder, and a positioning bolt is installed through the threaded through hole. The axially extending end of the positioning bolt in the blank holder abuts against the corresponding end of the aluminum alloy bar to be cut axially, thereby fixing the aluminum alloy bar to be cut in the blank holder.

[0010] The structure of the present utility model is simple and effective. By making the blank holder move horizontally and linearly at a constant speed on the top surface of the workbench, the part of the aluminum alloy bar to be cut protruding from the blank holder moves horizontally and linearly at a constant speed. When the part of the aluminum alloy bar to be cut protruding from the blank holder contacts the cutting saw, the part of the aluminum alloy bar to be cut protruding from the blank holder is cut by the cutting saw. Thus, the present utility model can realize uniform cutting operation, ensure the flatness of the cutting section, thereby eliminating manual participation in sawing, reducing the possibility of mechanical injury, and improving cutting quality and cutting safety.

[0011] A bolt is installed on one side of the blank holder of the present utility model, and the aluminum alloy bar to be cut is positioned and fixed by the positioning bolt. For aluminum alloy bars to be cut with different axial lengths, only the length of the positioning bolt extending into the blank holder needs to be adjusted. Thus, it can be applied to cutting blank materials of aluminum alloy bars to be cut with various shapes and lengths, and the installation and operation are quick and simple, and accurate uniform cutting of the bars can be carried out.

[0014] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0015] Such as Figure 1 、 Figure 2As shown in the figure, this embodiment discloses a tooling fixture applicable to automatic cutting of aluminum alloy bars by a bench band saw / wire saw, including a workbench 1 of the bench band saw / wire saw, in which a cutting saw 2 is vertically and penetratingly installed. A blank holder 3 is horizontally and linearly movably installed on the top surface of the workbench 1. The aluminum alloy bar 4 to be cut is axially and horizontally fixed in the blank holder 3, and a part of the aluminum alloy bar 4 to be cut protrudes from the blank holder 3. A horizontal linear motion driving mechanism 5 is installed on the top surface of the workbench 1. The blank holder 3 is driven by the horizontal linear motion driving mechanism 5 to perform horizontal linear motion on the top surface of the workbench 1. Thus, the aluminum alloy bar 4 to be cut is driven by the blank holder 3 to perform horizontal linear motion. The cutting saw 2 is located on the horizontal linear motion path of the part of the aluminum alloy bar 4 to be cut that protrudes from the blank holder 3. When the aluminum alloy bar 4 to be cut moves horizontally and linearly to contact the cutting saw 2, the cutting saw 2 completes the cutting of the part of the aluminum alloy bar 4 to be cut that protrudes from the blank holder 3.

[0016] In this embodiment, a moving platform is further provided on the top surface of the workbench 1. The moving platform is horizontally and linearly slidably installed on the top surface of the workbench 1. The blank holder 3 is fixed on the moving platform. The horizontal linear motion driving mechanism 5 is fixedly connected to the blank holder 3 or the moving platform. Thus, the moving platform and the blank holder 3 are driven by the horizontal linear motion driving mechanism 5 to perform overall horizontal linear motion.

[0017] Specifically, the moving platform is a trolley 6 provided on the top surface of the workbench 1. The bottom of the trolley 6 has sliders. A guiding groove 7 is further provided on the top surface of the workbench 6. The sliders at the bottom of the trolley 6 are slidably installed in the guiding groove 7. The wheels of the trolley 6 are in contact with the top surface of the workbench 1. The blank holder 3 is fixed on the top of the trolley. The horizontal linear motion driving machine 5 is fixedly connected to the blank holder 3 or the trolley 6. The blank holder 3 and the trolley 6 are driven by the horizontal linear motion driving machine 5 to perform overall horizontal linear motion.

[0018] In this embodiment, the horizontal linear motion driving machine 5 is a cylinder or a hydraulic cylinder. When the horizontal linear motion driving machine 5 is a cylinder or a hydraulic cylinder, the end of the piston rod of the cylinder or the hydraulic cylinder is fixedly connected to the blank holder 3 or the moving platform.

[0019] In this embodiment, the horizontal linear motion driving machine 5 can also adopt a lead screw slider mechanism.

The nut 5.2 is fixedly connected to the moving platform, or the nut 5.2 is fixedly connected to the blank holder 3 through a structurally stable triangular connecting block. Thus, the nut 5.2 is restricted from rotating, and thus forms a lead screw slider mechanism with the lead screw 5.1. When the motor 5.3 drives the lead screw 5.1 to rotate, the nut 5.2 drives the blank holder 3 and the moving platform to perform overall horizontal linear motion.

[0020] In this embodiment, the blank holder 3 is a horizontally placed U-shaped frame. The aluminum alloy bar 4 to be cut is axially horizontally placed in the U-shaped opening of the blank holder 3, and a part of the aluminum alloy bar 4 to be cut protrudes from the U-shaped opening of the blank holder 3. A threaded through hole 3.1 is provided on one U-shaped wall of the blank holder 3. A positioning bolt 3.2 is installed through the threaded through hole 3.1. The axially extending end of the positioning bolt 3.2 in the blank holder 3 abuts against the corresponding end of the aluminum alloy bar 4 to be cut axially. Thus, the aluminum alloy bar 4 to be cut is fixed in the blank holder 3 by the positioning bolt 3.2. For aluminum alloy bars 4 to be cut with different axial lengths, only the length of the part of the positioning bolt 3.2 extending into the blank holder 3 needs to be adjusted to be applicable to aluminum alloy bars 4 to be cut with different axial lengths.
