Description
Technical field:
The present invention relates to the folded block processing technique field, specifically is a kind of grinding technics of folded block.
Background technology:
Folded block refers to have the metal blocks of certain bending shape, and shape is comparatively complicated, exists more gradient and connects gradient, and gradient connects the characteristics at R angle.In the prior art, a kind of folded block is arranged, the external form of folded block is that side's body lacks one jiao, connects a gradient again for gradient connects the R angle on one jiao the cross section of disappearance, and the R angle is all tangent in the gradient of both sides, transitions smooth.To connect when the R angle connects the folded block of gradient more all be the mode that adopts the line cutting to this gradient of processing in the prior art, it is chronic that the mode of line cutting spends, the cost height, tangent plane is rough, precision is not high, working (machining) efficiency is very low, therefore can find abrasive method to process this folded block, just can improve machining accuracy and the working (machining) efficiency of folded block greatly.
Summary of the invention:
Technical problem to be solved by this invention is to provide the grinding technics of the folded block that a kind of process velocity is fast, precision is high.
A kind of grinding technics of folded block is characterized in that: comprising:
(1) selects materials: select square or be the metal derby of rectangular shape;
(2) make boost line;
(3) trimming wheel
(4) grind.
Described being specially as boost line chosen any summit of metal derby and is made as the B point, is to choose respectively at 2 on two side seamed edges on summit to be made as A and C respectively with the B point again; Cross A point and make part gradient ∠ BAE comprising side that A point and C order, make part gradient ∠ BCE comprising the side mistake C point that A point and C order, AE meets at the E point in CE; Get the H point at AE, cross the H point and make straight line OH, make OH ⊥ AE, get an I at CE, cross the I point and make straight line OI, make OI ⊥ CE, OI hands over OH in the O point, and OI=OH; Cross the C point and make CD ∥ AE and hand over AB in the D point, cross D and make DG ⊥ AE and hand over AE in the G point, cross E point and make EF ∥ BC and hand over AB in the F point, cross B and make BK ⊥ CD friendship CD in the K point.
Described trimming wheel is, use the gradient device to repair the gradient of (180 °-∠ AEC) size at emery wheel, and guarantee that this gradient area is not less than the area of section of the gradient of part, the gradient face of emery wheel can cover the required gradient cross section of grinding off of folded block fully when guaranteeing to grind, and practical R angle trimmer repairs the fillet of ∠ AEC size on the gradient of emery wheel.
Described grinding was before crushing, this part is placed on the gradient platform of ∠ BCD size and fixing, part after fixing is placed on the grinding machine magnetic platform, the B point is touched in the emery wheel bottom, the electronic ruler of grinding machine makes zero up and down, the length of BK under the emery wheel, △ BCD is partly ground off, keep the motionless below that on the gradient platform gradient platform is placed on the emery wheel that trims that is placed on of part, the gradient size of gradient platform is adjusted into ∠ AEF size, this moment, the cross section at CD place was parallel with the magnetic platform of grinding machine, touch the cross section of CD with the bottom of emery wheel, the grinding machine electronic ruler makes zero up and down, DG length under the emery wheel, touch part D point grinding machine left and right sides electronic ruler with the inclined-plane of emery wheel and make zero, emery wheel is advanced the length of CD.
The invention has the beneficial effects as follows: the present invention can improve process velocity and the machining accuracy of folded block greatly, and cost of manufacture is low, and the product quality height is conducive to increase economic benefit.
Description of drawings:
Fig. 1 is folded block structural representation of the present invention.
Fig. 2 makes the boost line schematic diagram for the present invention.
The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and be easy to understand in effect, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, 2,
A kind of grinding technics of folded block, folded block are that a gradient 1 connects the folded block that the R2 angle connects gradient 3 again, comprising:
(1) selects materials: select square or be the metal derby of rectangular shape;
(2) make boost line;
(3) trimming wheel
(4) grind.
Being specially as boost line and choosing any summit of metal derby and to be made as the B point, is to choose respectively at 2 on two side seamed edges on summit to be made as A and C respectively with the B point again; Cross A point and make part gradient ∠ BAE comprising side that A point and C order, make part gradient ∠ BCE comprising the side mistake C point that A point and C order, AE meets at the E point in CE; Get the H point at AE, cross the H point and make straight line OH, make OH ⊥ AE, get an I at CE, cross the I point and make straight line OI, make OI ⊥ CE, OI hands over OH in the O point, and OI=OH; Cross the C point and make CD ∥ AE and hand over AB in the D point, cross D and make DG ⊥ AE and hand over AE in the G point, cross E point and make EF ∥ BC and hand over AB in the F point, cross B and make BK ⊥ CD friendship CD in the K point.
Trimming wheel is, use the gradient device to repair the gradient of (180 °-∠ AEC) size at emery wheel, and guarantee that this gradient area is not less than the area of section of the gradient of part, the gradient face of emery wheel can cover the required gradient cross section of grinding off of folded block fully when guaranteeing to grind, and practical R angle trimmer repairs the fillet of ∠ AEC size on the gradient of emery wheel.
Grind to before crushing, this part is placed on the gradient platform of ∠ BCD size and fixing, part after fixing is placed on the grinding machine magnetic platform, the B point is touched in the emery wheel bottom, the electronic ruler of grinding machine makes zero up and down, the length of BK under the emery wheel, △ BCD is partly ground off, keep the motionless below that on the gradient platform gradient platform is placed on the emery wheel that trims that is placed on of part, the gradient size of gradient platform is adjusted into ∠ AEF size, this moment, the cross section at CD place was parallel with the magnetic platform of grinding machine, touch the cross section of CD with the bottom of emery wheel, the grinding machine electronic ruler makes zero up and down, DG length under the emery wheel, touch part D point grinding machine left and right sides electronic ruler with the inclined-plane of emery wheel and make zero, emery wheel is advanced the length of CD.
