The utility model discloses to the high -usage of sheet metal, avoided the waste, and work efficiency is high.
Description
Technical field
The utility model relates to the bending field of rod, section bar or pipe, is specifically related to a kind of thin plate bending device.
Background technology
In mechanical processing process, often need to process thin plate, make the thin plate after processing be circular arc.Traditional was adopt the processing of punch press blanking to the processing method of thin plate in the past.Punch press is a punching type forcing press.Blanking refers to and utilizes stamping-out to obtain the product of certain profile or the process for stamping of blank.Stamping-out utilizes punch die to make portion of material or operation and another part material, workpiece or a kind of stamping procedure be separated that given up.Stamping-out utilizes the cutting edge of punch die to make plate produce detrusion along certain outline line and be separated.So utilize the anti-method of punch press blanking to add man-hour to thin plate bending, needs will carry out cutting to thin plate, and the utilization rate of material is low, waste is serious.
Utility model content
The purpose of this utility model is providing a kind of thin plate utilization rate high, avoids wasting and the high thin plate bending device of efficiency.
For achieving the above object, the technical solution of the utility model is as follows: a kind of thin plate bending device, comprises workbench, frame, compression hydraulic cylinder, counterdie and bending hydraulic cylinder; Described workbench is arranged in frame, and described compression hydraulic cylinder is arranged on upper rack, and described compression hydraulic cylinder piston rod is connected with patrix, and described bending hydraulic cylinder is arranged in frame and described bending hydraulic cylinder is vertical with described compression hydraulic cylinder; Described bending hydraulic cylinder piston rod is connected with counterdie; Described counterdie is arranged on the table.
Operation principle of the present utility model is as follows: compress hydraulic cylinder body and be vertically fixed in frame, and compress hydraulic cylinder piston rod and be connected with patrix, patrix can only move up and down in the guide rail of frame.Compress hydraulic cylinder to be compressed on the table by thin plate by patrix, bending hydraulic cylinder body is fixed in frame, and bending hydraulic cylinder piston rod is connected with counterdie.Counterdie moves left and right on the table, when counterdie moves to thin plate direction, to thin plate force, by thin plate bending.
The beneficial effects of the utility model are: be respectively equipped with in frame and compress hydraulic cylinder and bending hydraulic cylinder, and it is vertical with bending hydraulic cylinder to compress hydraulic cylinder.Compress hydraulic cylinder to compress thin plate, bending hydraulic cylinder directly exerts a force thin plate bending to thin plate.Compared with traditional punch press blanking, the utility model directly carries out bending to thin plate, without the need to carrying out cutting to thin plate after blanking, avoiding waste and saving the time, improve operating efficiency.
Further, described compression hydraulic cylinder is double acting hydraulic cylinder, and double acting hydraulic cylinder can control the motion of both direction, is convenient to move the gap controlled between upper die and lower die by controlling patrix, guarantees that workpiece can only at bending Direction distortion, wrinkle resistant.
Further, described bending hydraulic cylinder is double-action hydraulic, and be convenient to accurately control width of the workpiece size, repeatable accuracy is high.
Further, described compression hydraulic cylinder top is provided with screw rod, and screw flight is connected with the adjusting nut of adjustable hydraulic cylinder travel, and for accurately controlling the stroke compressing hydraulic cylinder, repeatable accuracy is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model thin plate bending device embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: 1-frame; 2-workbench; 3-compresses hydraulic cylinder; 4-patrix; 5-counterdie; 6-bending hydraulic cylinder.
Embodiment is substantially as shown in Figure 1: a kind of thin plate bending device, comprises workbench 2, frame 1, compresses hydraulic cylinder 3, patrix 4, counterdie 5 and bending hydraulic cylinder 6.Workbench 2 is connected by screw in frame 1.Because there is the power of horizontal direction between workbench 2 and counterdie 5, workbench 2 and frame 1, with while being threaded, need add location finger setting.Compress hydraulic cylinder 3 and be fixed on frame 1 top, compress hydraulic cylinder 3 piston rod and be connected with patrix 4, bending hydraulic cylinder 6 is bolted in frame 1 and bending hydraulic cylinder 6 is vertical with compressing hydraulic cylinder 3; Bending hydraulic cylinder 6 piston rod is connected with counterdie 5.Compressing hydraulic cylinder 3 be double acting hydraulic cylinder, is convenient to the gap between control upper die and lower die, guarantees that workpiece can only at bending Direction distortion, wrinkle resistant.Bending hydraulic cylinder 6 is double-action hydraulic, and be convenient to accurately control width of the workpiece size, repeatable accuracy is high.Compress hydraulic cylinder top and be provided with screw rod, screw rod is through frame, and screw flight is connected with the adjusting nut of adjustable hydraulic cylinder travel, and for accurately controlling the stroke compressing hydraulic cylinder, repeatable accuracy is high.
Compressing hydraulic cylinder 3 cylinder body is vertically fixed in frame 1, and compress hydraulic cylinder 3 piston rod and be connected with patrix 4, patrix 4 can only move up and down in the guide rail of frame 1.Compressing hydraulic cylinder 3 is pressed on workbench 2 by patrix 4 by thin plate, and bending hydraulic cylinder 6 is fixed in frame 1, and bending hydraulic cylinder 6 piston rod is connected with counterdie 5.Counterdie 5 moves left and right on workbench 2, when counterdie 5 moves to thin plate direction, to thin plate force, by thin plate bending.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
