In the device known in this field the adjustment in transverse and inclined directions has been performed up till now by means of four adjusting bolts. The adjustment herewith is very time consuming, especially with respect to the adjustment in a more or less inclined position of the holding means, which is necessary, because it is a well known fact, that the topside of the shaft of the bolt to be treated, i.e., at its head, mostly shows the tendency to become thicker than its bottomside. This is the consequence of the fact that when a screwthread is rolled the material at the bottomside can somewhat flow in its longitudinal direction.
The result is, that a greater force is exerted on the two topmost adjusting bolts than on the two lowermost bolts, so that said bolts penetrate into the material of the holder and form small pits therein and the adjusted position is altered. Then a further adjustment of the holding means becomes necessary.
In order to obviate the disadvantages mentioned above and to simplify the adjusting operation, in the device according to the present invention the holding means is provided in its longitudinal direction parallel to the direction of movement of the reciprocable rolling tool, with a cleft ending at its bottom side in a slitshaped bore also extending in its longitudinal direction, and is provided at its topside with a groove in which an adjustable member is provided for controlling the width of said groove.
In an embodiment of the device according to the invention the groove in the topside of the holding means has at least one hollow side wall extending conically and in said groove a wedge which is adjustable in longitudinal direction is provided, the shape of said wedge being adapted to the shape of said groove.
In another embodiment of the device according to the invention the means for carrying into effect the right diameter of the screwthread exist of at least two adjacent adjustable wedges positioned between the holding means and the frame of the device.
In the device according to the invention the preferably vertically adjustable wedges are transversely curved at the side of the holding means, said curved sides cooperating with correspondingly curved parts of the holding means.
In the drawings the device as was used up till now and an embodiment of the device according to the invention are illustrated by way of example.
FIG. 1 shows a side elevation of a prior art machine with a partial cross-section along the line I-I in FIG. 2 of the important portion of the known machine.
FIG. 2 shows a cross-section of the prior art machine along the line iI-ll in FIG. 1.
FIG. 3 shows a plan view of the important portion of the embodiment according to the invention.
FIG. 4 shows a vertical cross-section along the line lV-lV in FIG. 3.
FIG. 5 shows a vertical section along the line V-V in FIG. 3.
FIG. 6 shows a side elevation of the holding means of the stationary roller.
FIG. 7 shows a plan view of the holding means of the stationary roller.
In the known embodiment of a prior art machine as shown in FIGS. 1 and 2 the transverse and inclined adjustment of the block 1, in which the stationary screwthread roller 2 is positioned, takes place by means of the four adjustment bolts 3, 4, 5, 6 and two drawbolts 7, 8. Last-mentioned bolts cooperate with nutshaped members 9 and 10 rotatable within said block, said nut-shaped members having an exterior of cylinders. The reciprocable screwthread roller is indicated with Ill. Said roller 11 is arranged in the carriage 12. A treated bolt is indicated with 13. Furthermore the holding means 1 is fastened in its adjusted position by the bolt 14. The adjustment of the holder 1 in vertical direction takes place by means of the wedges 15 and 16.
The adjusting operation of the parts mentioned above is very time-consuming, especially for the more or less inclined adjustment of the holding means. For, said inclined adjustment is necessary because it is a known fact that the top side of the shaft of the bolt to be treated, i.e., its head, mostly shows the tendency to become thicker than its bottom side. This is the consequence of the fact that the material at the bottom side can flow a little lengthwise.
The result is that a greater force is exerted on the two topmost adjusting bolts than on the two lowermost bolts, so that said bolts penetrate into the material of the holding means and form small pits therein and the adjusted position is altered again. Then a further adjustment of the holding means becomes necessary.
In the embodiment of the device according to the invention the reciprocable, non-adjustable screwthread roller 11 is also fastened in the carriage 12 which is adapted to carry out a reciprocable movement in a known manner by means of a connecting rod 17.
When an object 13 to be rolled is moved to the screwthread rollers 2 and 4 through the inserting finger 34 after being supplied by the supply ridges i8, 19, said rollers will carry said object along and provide same in a rotating manner with screwthread.
The stationary roller block 2 is adjustably fastened in the holding means I in the frame 22 by means of clamping members 20, 21.
Said holding means 1 in the form of a block, (FIGS. 6 and 7) is provided over its entire length parallel to the direction of movement of the reciprocable screwthread roller 11 with a longitudinal cleft 23 extending into or ending at the bottom side as seen in FIG. 6 in a slitshaped bore 24. Furthermore said holding means 1 is provided at its topside with a ball-shaped groove 25 having a arcuate-shaped sides, an adjusting wedge 26 adapted to the shape of the groove 25, said wedge being lengthwise adjustable by means of an adjusting bolt 27 as seen in FIG. 3.
If said adjustment of the wedge 26 is carried out and said wedge e.g., is adjusted to the lefthand side as seen in FIG. 3, it will be clear that the portion of the holding means 1 in which the screwthread roller 2 is fastened, will spread out while resiliently pivoting about an imaginary pivot x (FIG. 6), said pivot thus lying underneath the rolling member 2.
Thereby the roller member 2 will spread out more at its topside than at its bottom side so that said roller member 2 will be placed more or less inclined.
As to the adjustment to the right screwthread diameter to be rolled there are two conical adjusting wedges 28 and 29 which are adapted to adjust the holding means 1 forwardly and backwardly by means of adjusting bolts 30 and 31. Said adjusting wedges 28 and 29 together form a supporting surface that is sufficiently large, so that a maladjustment by the formation of pits is not possible.
Because of the provision of the two adjusting wedges 28 and 29 the holding means 1 needs only to be fastened by a single bolt 32. Besides the fact that said bolt 32 pulls the holding means 1, with the insertion of the two adjusting wedges 28 and 29, against the frame 22, said holding means 1 is also pressed downwardly onto the frame 22 by the conical shape of said adjusting wedges 28 and 29, said two wedges and 16 being positioned for that purpose underneath said screwthread roller in the frame 22.
The adjusting operation of the device according to the present invention takes place as follows.
If it appears that the rolled screwthread of the article 13 has not the same diameter everywhere, then it will be necessary to give a more or less inclination to the stationary block 1. For that purpose, after the bolt 32 has been unscrewed a little, only the adjusting bolt 27 needs to be rotated, so that the adjusting wedge 26 is moved lengthwise and the portion of the holding means 1, in which the roller member 2 is fastened, is placed more or less inclined. Thereafter only the bolt 32 needs to be refastened.
If it is necessary to readjust the screwthread diameter of the article 13 to be rolled, only the two adjusting bolts 30 and 31 need to be rotated after the bolt 32 has been unscrewed, so that the. wedges 28 and 29 are adjusted vertically to displace the holding means 1 rearwardly or forwardly and the roller 2 is positioned nearer to or further from the roller 11.
In order to adjust the pitch, after the bolt 32 is unscrewed, the adjusting wedge 15 underneath the holding means 1 is adjusted lengthwise by means of the bolt 33, so that the holding means 1 is adjusted vertically.
From the above it will be clear that more particularly the adjustment of inclination of the stationary rolling member 2 has become much more simple and can be carried out much quicker. in the known holding means first three bolts must be unscrewed before the inclination can be adjusted by means of four adjusting bolts. In the novel device this operation is carried out after only one bolt has been unscrewed by means of only one adjusting bolt. Also the displacement in a forward or a rearward direction is much more simple. Formerly this could only take place by unscrewing three bolts and the adjustment by means of four bolts. According to the present invention this operation is carried out by means of only two adjusting bolts and after that only one bolt has been unscrewed.
Furthermore it is impossible that through the formation of pits in the material of the holding means a maladjustment can take place, because the two wedges 28 and 29 together form a surface that is sufficiently large to absorb the acting forces, so that no formation of pits is possible.
