Description
Technical field
The utility model relates to a kind of mould, more particularly, is the concealed waste knife mechanism of a kind of edger.
Background technology
in stamping factory, especially in automated production, often when producing stamping parts, because the size of raw steel plate is more much bigger than the size of stamping parts, so all trimming operation can be related in process of production.Occur that trimming waste material is stuck in the problem on mould in order to prevent the waste material excised in process of production because of oversize, so shaving die four weekly assembly is designed with the waste knife of many handles, therefore before excision excess stock, can first cut off unnecessary material, unnecessary material is cut into multistage, then unnecessary material is being excised from stamping parts, like this, just can effectively prevent trimming waste material to be stuck in problem on mould.
Although this can solve trimming waste material well and be stuck in problem on mould, also bring very large trouble to production.At present, edger is substantially all, after employing is first cut into some sections unnecessary steel plate materials, excising again.But, after steel plate materials is first cut into some sections, the integral rigidity of these unnecessary steel plate materialses can be caused to decline, thus in the process of excision excess stock, steel plate materials can attach the useless stage in shear stage---tear the stage.The surface of steel plate materials can be torn in the stage of tearing, thus produce a large amount of iron filings, these iron filings can drop along with moving upward of patrix in the profile of counterdie, when continuing punching production, stamping parts below can be made to produce a large amount of convex closures, thus cause reprocessing in enormous quantities of stamping parts, cause once rolling off the production line the significantly reduction of qualification rate, reduce the quality of product, the particularly exigent exterior panel of Surface Quality, when being difficult to reprocess because convex closure occurs in batch, process can only being scrapped to stamping parts, increasing production cost widely.
Utility model content
The utility model is brought on punch to solve the iron filings produced in trimming operation, thus causes stamping parts to occur a large amount of convex closures, causes the problem of reprocessing in enormous quantities of stamping parts, proposes the concealed waste knife mechanism of a kind of edger.
To achieve these goals, the utility model is by the following technical solutions:
A kind of concealed waste knife mechanism of edger, comprise main edge-trimming cutter, back-moving spring, main cutoff tool, it is characterized in that, also comprise movable edge-trimming cutter and limited block, the main cutting edge of described main edge-trimming cutter, movable edge-trimming cutter and main cutoff tool is close together, and connects into a line, the composition edge-trimming cutter edge of a knife, main cutoff tool side is the cutoff tool edge of a knife, and movable edge-trimming cutter is between main edge-trimming cutter and main cutoff tool, is formed and is vertically slidably matched.After raw material punch forming, trimming and cut-out can be carried out to excess stock simultaneously, avoid the process of tearing, prevent iron filings.
As preferably, main edge-trimming cutter is connected and fixed by bolt and patrix, and its edge of a knife is straight line.
As preferably, main cutoff tool is connected and fixed by bolt and patrix, its edge-trimming cutter edge of a knife is straight line, and its cutoff tool edge of a knife is straight line, and mutually vertical, main cutoff tool is connected and fixed by bolt and patrix, its edge-trimming cutter edge of a knife is straight line, and its cutoff tool edge of a knife is straight line, and mutually vertical, main cutoff tool as edge-trimming cutter, also will should use as cutoff tool.
As preferably, movable edge-trimming cutter is arranged between main edge-trimming cutter and main cutoff tool, during as edge-trimming cutter, edge of a knife front is a plane, bottom surface is also a plane, and two planes become vertical plane, during as cutoff tool, the upwards indentation of active edges cutter, depth of cut space when leaving cut-out to main cutoff tool.
As preferably, back-moving spring is arranged on the top of movable edge-trimming cutter, is fixed on patrix, and in its natural state, movable edge-trimming cutter, main edge-trimming cutter and main cutoff tool front and bottom surface all form smooth flat to back-moving spring.
As preferably, limited block is bolted on patrix, is close to movable edge-trimming cutter, is formed and is vertically slidably matched, and movable edge-trimming cutter can only slide by vertical direction.
As preferably, main edge-trimming cutter and main cutoff tool are equipped with step with the contact surface of movable edge-trimming cutter, reduce contact surface area, reduce frictional force, length of bench is greater than the counterdie waste knife depth of cut, ensure that the smoothness that movable edge-trimming cutter vertically slides.
As preferably, back-moving spring is nitrogen spring.It is little that nitrogen spring has volume, and elastic force is large, and the life-span is long, the feature that elastic force pressure is constant, and volume I saves die space, and life-span length can reduce mold repair number of times.
Therefore, the utility model has following beneficial effect:
Trimming is cut off two procedures and is carried out simultaneously, avoids the process of tearing, eliminates the generation of iron filings, reduce repair rate and the scrappage of stamping parts, also reduce production cost and improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: 1. main edge-trimming cutter, 2. back-moving spring, 3. movable edge-trimming cutter, 4. main cutoff tool, 5 limited blocks.
Detailed description of the invention
embodiment 1
The concealed waste knife mechanism of a kind of edger as shown in Figure 1, comprise main edge-trimming cutter 1, back-moving spring 2, main cutoff tool 4, characterized by further comprising movable edge-trimming cutter 3 and limited block 5, the main cutting edge of described main edge-trimming cutter 1, movable edge-trimming cutter 3 and main cutoff tool 4 is close together, connect into a line, the composition edge-trimming cutter edge of a knife, main cutoff tool 4 medial surface is the cutoff tool edge of a knife, movable edge-trimming cutter 3 is between main edge-trimming cutter 1 and main cutoff tool 4, is formed and is vertically slidably matched.Main edge-trimming cutter 1 is bolted on patrix, and its edge of a knife is straight line.Main cutoff tool 4 is connected and fixed by bolt and patrix, and its edge-trimming cutter edge of a knife is straight line, and its cutoff tool edge of a knife is straight line, and mutually vertical.Spring is arranged on the top of movable edge-trimming cutter 3, is fixed on patrix.Limited block is bolted on patrix, is close to movable edge-trimming cutter 3, is formed and is vertically slidably matched.Main edge-trimming cutter 1 and main cutoff tool 4 are equipped with step with the contact surface of movable edge-trimming cutter 3, and length of bench is greater than the counterdie waste knife depth of cut.Back-moving spring is nitrogen spring.
After raw material punch forming, patrix continues to walk downward, and touches raw material, trimming and cut-out operation are carried out simultaneously, movable edge-trimming cutter 3 is subject to the effect of counterdie waste knife power, upward sliding, and back-moving spring 2 compresses, trimming and cut-out work complete, excess waste falls, and patrix is up walked, and back-moving spring 2 recovers nature, movable edge-trimming cutter 3 slides down to home position, repeats this process.Trimming and cut-out operation are carried out simultaneously, avoid the process of tearing, prevent the generation of iron filings.
