Abstract
The utility model aims to provide a combined bending tool, which effectively avoids tool jamming in the prior art, and comprises a tool bit and a main clamp. The combined bending tool is technically characterized in that the tool bit is a single body made of a carbon spring steel plate and is assembled between a clamping block made of 45C carbon structural steel and the main clamp, and the tool bit is fixedly combined together with the clamping block and the main clamp by the aid of a fastening bolt. The combined bending tool is reasonable in design, simple in structure, easy in assembly and convenient in maintenance and adjustment, precious metal is saved, the quality of workpieces is improved remarkably, and cost is lowered.
Description
Technical field
The utility model relates to and a kind ofly sheet metal is carried out the mould that the bending operation is used, particularly a kind of patrix that is directly installed on operation on the hydraulic bending press, i.e. combined type bending cutter.It is mainly used in the bending behind the sheet metal processing bending groove, also can be applied to the direct bending of thin metal blank.
Background technology
Panel beating is at present carried out the most hydraulic bending press that use of bending operation to sheet metal, carries out operation through the special-purpose or general upper and lower mould that is installed on the hydraulic bending press.Patrix adopts and to be commonly called as the monoblock type bending cutter (shown in Fig. 3) into " bending cutter ", counterdie adopt with processed workpiece bending and molding after the corresponding to V mouth of shape counterdie.Wherein the cramping body of monoblock type bending cutter and cutter head adopt same precious metal Cr12MoV material to process one, form through the surface hardening heat treatment process.In process, require to possess less outside bending fillet after some workpiece bending, also require to have enough plate face intensity simultaneously.Therefore, the operational method that adopts usually is to process bending groove (being commonly called as channeling) at the sheet metal bending part, to reduce the material thickness of sheet metal bending part, utilizes special use or general upper and lower mould on bender, to carry out operation then.Because the bending groove is in the bending process; If the angle design of the thickness of cutter head and point of a knife is improper, when the distortion of bending groove arrives to a certain degree, will contact (being commonly called as the folder cutter) so with " bending cutter "; Cause the mass defect of bending workpieces easily, even cause workpiece to scrap.
The utility model content
The purpose of the utility model provides a kind of combined type bending cutter, and it has avoided the generation of the folder cutter phenomenon of prior art existence effectively, and it is reasonable in design; Simple in structure, assembling is easy, maintenance, easy to adjust; Save precious metal, significantly improve workpiece quality, reduce cost.
The technical scheme that the utility model adopted is: this combined type bending cutter comprises cutter head and main cramping body; Its technical essential is: the monomer that said cutter head adopts carbon spring steel sheet material to process; Cutter head is assembled in and adopts between the clamp and main cramping body that No. 45 structural carbon steels process, and utilizes fastening bolt that cutter head and clamp are in the same place with main cramping body secure bond.
The thickness of said cutter head less than the bending groove bending of workpiece after the 0.2mm of theoretical width of rebate, the angle that point of a knife forms is 86 °.
Advantage and the good effect that the utlity model has are: because the structure of the utility model is on general bending cutter basis, to improve, the monomer that cutter head adopts normal carbon spring steel sheet material to process, cutter head are assembled in and adopt between the clamp and main cramping body that common No. 45 structural carbon steels process; And utilize fastening bolt that cutter head and clamp are in the same place with main cramping body secure bond; Active force contacts with " bending groove " bottom of sheet material through " cutter head " and fulfils assignment, and wherein cutter head adopts the normal carbon spring steel to make, and handles through heat-treatment quenching; So it is not only reasonable in design; Simple in structure, assembling is easy, maintenance, easy to adjust; And the saving precious metal, manufacturing expense is also more much lower than existing general integrated formula bending cutter expense.Existing " bending cutter " whole Cr12MoV processing and fabricating that adopts is handled Quenching Treatment through surface heat again, and Master Cost and manufacturing cost are far above the expense of novel combination type bending cutter.
The selection of the thickness of cutter head and the angle of point of a knife, cutter head height etc. should increase and decrease according to the thickness of institute's machining sheet, to accomplish the bending of opening " bending groove " sheet material of different-thickness.Therefore, the thickness of cutter head should be selected the 0.2mm less than theoretical width of rebate after workpiece " fluting bending " moulding, and clamping cutter head phenomenon just can not take place during bending so; If the angle that point of a knife forms is designed to 86 °, just can solve the problem of deformation resilience; Select the sheet material of the corresponding different-thickness of different cutter head height, can guarantee that the sheet material inner surface does not contact with main cramping body and clamp in the bending overall process.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of structural representation of the utility model;
Fig. 2 is the structural representation of sheet material processing bending groove;
Fig. 3 is existing monoblock type bending knife structure sketch map.
Sequence number explanation among the figure: 1 main cramping body, 2 clamps, 3 cutter heads, 4 fastening bolts, 5 workpiece.
The specific embodiment
Specify the concrete structure of the utility model according to Fig. 1～3.This combined type bending cutter is that sheet metal is carried out the patrix that the bending operation is used, counterdie adopt with processed workpiece bending and molding after the general counterdie of the corresponding to V mouth of shape.
This combined type bending cutter comprises parts such as cutter head 3, main cramping body 1 and clamp 2.Wherein cutter head 3 adopts the monomer that normal carbon spring steel sheet material is processed, and the selection of the thickness of cutter head 3 and the angle of point of a knife, cutter head 3 height etc. should increase and decrease according to the sheet metal thickness of workpiece 5, to accomplish the bending of opening " bending groove " of different-thickness sheet material.Clamp 2 adopts common No. 45 structural carbon steels to process with main cramping body 1.Cutter head 3 is assembled between clamp 2 and the main cramping body 1, and utilizes fastening bolt 4 that cutter head 3 and clamp 2 are in the same place with main cramping body 1 secure bond.In order to make workpiece 5 not press from both sides the cutter phenomenon when the bending, can the thickness of cutter head 3 be processed into 0.2mm less than theoretical width of rebate after the bending groove bending of workpiece 5.The angle that point of a knife forms is 86 °, can solve the problem of deformation resilience.
Suitable cutter head 3 height can guarantee in the bending deformation process after the bending workpiece 5 not with main cramping body 1 and clamp 2 contact-impacts.After accomplishing the bending operation, because the deadweight of workpiece 5 after the bending makes it when the bending cutter rises, cutter head 3 breaks away from workpiece 5 naturally.
When carrying out operation, should select the cutter head of proper height, with clamp 2 cutter head 3 is fastened on the main cramping body 1, accomplish the assembling of combined type bending cutter with interior hexagonal fastening bolt 4 according to the sheet thickness of workpiece 5; It is installed on the bender again, selects the general counterdie of 8-10mmV mouth, the bending groove center line of cutter head 3 center line alignment pieces 5 according to common bending operation rules operation, can be accomplished the bending operation.
