Existing this beam tube mould, when to clamp shape of cross section be the automobile stabilizer bar termination of rectangle, usually there will be six pieces of calibration blocks and clamps not strongly loosening phenomenon by causing, and then affect the product qualified rate bent.
Summary of the invention
It can stable holding shape of cross section be the beam tube mould of the automobile stabilizer bar termination of rectangle that technical problem to be solved in the utility model is to provide a kind of in Cold Roll Forming Process.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
For the beam tube mould of automobile stabilizer bar, comprise six pieces of calibration blocks, these six pieces of calibration blocks circumferentially arrange, and each calibration block can radially move between released position and clip position, and each calibration block comprises the outer face of circular arc and the clamping face for the termination that clamps automobile stabilizer bar; When six pieces of calibration blocks are all in clip position, the outer face of these six pieces of calibration blocks is positioned at circumferentially same, and the clamping face of these six pieces of calibration blocks surround one can the rectangular channel of termination of accommodating automobile stabilizer bar; Wherein, six pieces of calibration blocks comprise the first calibration block, the second calibration block, the 3rd calibration block, the 4th calibration block, the 5th calibration block and the 6th calibration block; Toward each other, and the clamping face of the first calibration block and the second calibration block is plane for first calibration block and the second calibration block; 3rd calibration block and the 4th calibration block lay respectively at the both sides of the first calibration block, 5th calibration block and the 6th calibration block lay respectively at the both sides of the second calibration block, three, the clamping face of the 4th, the 5th and the 6th calibration block is all rectangular in shape, three, the clamping face of the 4th, the 5th and the 6th calibration block forms four angles of rectangular channel respectively, its feature is, the width of the clamping face of the first calibration block and the second calibration block is 3/1 to five/2nds of the width of the termination of automobile stabilizer bar.
Adopting after technique scheme, increasing the first calibration block and the second calibration block when clamping and the contact area of automobile stabilizer bar termination, improve and stability is bent to automobile stabilizer bar, thus the product qualified rate bent is increased dramatically.
Accompanying drawing explanation
Six pieces of calibration blocks that Fig. 1 shows existing beam tube mould are in cross-sectional view during clip position.
Fig. 2 shows cross-sectional view when being in clip position according to six pieces of calibration blocks of the beam tube mould of the utility model one embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Applicant by carefully analyzing existing beam tube mould, find the first calibration block of existing beam tube mould and the clamping face of the second calibration block and the contact area of automobile stabilizer bar termination too small be cause clamping not strongly the main cause leaned on.Because in clamping process, the side being easy to the clamping face that there will be the 3rd, the 4th, the 5th and the 6th calibration block has touched the termination 7 of automobile stabilizer bar, thus stop motion, and the upper and lower faces of the clamping face of the 3rd, the 4th, the 5th and the 6th calibration block is not closely contacted to the phenomenon of the termination 7 of automobile stabilizer bar.The first calibration block is now only had to contact with the upper and lower surface of termination 7 respectively with the clamping face of the second calibration block.And as shown in Figure 1, existing first calibration block and the clamping face of the second calibration block and the contact area of workpiece 7 very little, the width of the clamping face of the first calibration block and the second calibration block is all approximately 5 percent of the width of termination 7, equipment cannot be exerted oneself conducts completely on termination 7, thus causing clamping unstable, the location of termination 7 is unreliable.
Refer to Fig. 2.According to the beam tube mould for automobile stabilizer bar of the utility model one embodiment, comprise the first calibration block 1, second calibration block 2, the 3rd calibration block 3, the 4th calibration block 4, the 5th calibration block 5 and the 6th calibration block 6.These six pieces of calibration blocks circumferentially arrange, and each calibration block can radially move between released position and clip position, and each calibration block comprises the outer face 10a of circular arc and the clamping face 10b for the termination 7 that clamps automobile stabilizer bar.When six pieces of calibration blocks are all in clip position, the outer face 10a of these six pieces of calibration blocks is positioned at circumferentially same, and the clamping face 10b of these six pieces of calibration blocks surround one can the rectangular channel 9 of termination of accommodating described automobile stabilizer bar.Wherein, toward each other, and the clamping face of the first calibration block 1 and the second calibration block 2 is plane for the first calibration block 1 and the second calibration block 2; 3rd calibration block 3 and the 4th calibration block 4 lay respectively at the both sides of the first calibration block 1,5th calibration block 5 and the 6th calibration block 6 lay respectively at the both sides of the second calibration block 2, three, the clamping face of the 4th, the 5th and the 6th calibration block is all rectangular in shape, and the clamping face of the 3rd, the 4th, the 5th and the 6th calibration block forms four angles of rectangular channel 9 respectively.The width of the clamping face of the first calibration block and the second calibration block is 3/1 to five/2nds of the width W of the termination 7 of automobile stabilizer bar.
In the present embodiment, symmetrically, the width of the clamping face of the first calibration block 1 and the second calibration block 2 is also equal, is L, i.e. L=W/2 ~ 3W/5 for the first calibration block 1 and the second calibration block 2.3rd calibration block 3 and the 4th calibration block 4 lay respectively at the both sides of the first calibration block 1 with being mutually symmetrical, and the 5th calibration block 5 and the 6th calibration block 6 lay respectively at the both sides of the second calibration block 2 with being mutually symmetrical.
Compared with existing beam tube mould, the utility model passes through the width of the clamping face of increase first calibration block 1 and the second calibration block 2, increase the first calibration block and the second calibration block when clamping and the contact area of automobile stabilizer bar termination, improve and stability is bent to automobile stabilizer bar, thus the product qualified rate bent is increased dramatically.
