[Detailed Description of the Invention] [Industrial application] The present invention relates to a device for applying a label, an end surface grinding, an end surface engraving, etc. to an end of a material having a circular cross section such as a round bar and a pipe material. is there.

[Conventional technology]

As a conventionally known device, the chamfering device shown below is known as one of end processing devices for circular members having different diameters. That is, these are, for example, Japanese Utility Model No. 60-42553 and Japanese Utility Model No. 63-67061. The former has, in front of the rotary grindstone 6, a screw thread 31 having a high spiral height and a screw thread 33 having a high spiral height and a low screw height 33 having a spiral shape formed on the outer peripheral portion. A plurality of spiral rollers are arranged rotatably, and a stopper member 7 is arranged above the grindstone 6 in parallel with the axis of the rotary grindstone 6 (see FIGS. 4 and 5). ).

The latter has, instead of the spiral roller, at least two spiral rollers 3 and 32 having spiral threads 31 and 33 on the outer peripheral portion thereof, and the pitches of the threads 31 and 33 are different from each other, and these spiral rollers 3 and 32. Holds the roller so that it can be moved up and down, and at least two spiral rollers 3,
One of the 32 spiral rollers 3 or 32 is replaced with a roller switching device 34 for switching to a round bar supporting position at a constant height position (FIGS. 6, 7, and 8). reference).

Each of these conventional devices is provided, for example, independently of a refining line of a steelmaking factory.

Therefore, for the machining process such as chamfering, after carrying with a crane etc. from inside the adjusting line one by one, after chamfering etc.,
In addition, it was said to return to the adjustment line.

[Problems to be solved by the invention]

However, in the above example, the provision of an end processing step such as chamfering independently of the trimming line stagnates the flow of the trimming line here.

Therefore, I would like to somehow eliminate this stagnation and improve the efficiency of the adjustment.

Then, as a result of various studies, the inventors of the present invention succeeded in placing this in the adjusting line.

[Means for solving problems]

The present invention provides the above-mentioned conventional chamfering and other processing equipment between the walking beams of the trimming line, and smoothly chamfers circular cross-section materials of various diameters flowing in the trimming line by using the same walking beam. It is designed to be capable of processing end portions such as, and the gist thereof is as follows. That is, a pedestal in which a plurality of circular cross-section members are arranged in parallel at the same time, and at the end of the pedestal, among the circular cross-section members handled by the pedestal, a groove shape having a pitch substantially the same as the diameter of a thin round member, Between a walking beam for traverse feed (including Rechen), which extends in a direction orthogonal to the axis of the circular member having a circular cross section and is arranged so as to be able to traverse at the same time, which is arranged in parallel with the frame, and between the walking beams. A thread having an axis parallel to the extending direction of the walking beam, the pitch of at least one thread being approximately the same as the groove pitch of the walking beam, and the other thread having a multiple pitch thereof. It is a spiral roller that is both ridged and rotatable and has different pitches, or consists of rollers with different pitches of threads, and these rollers with different pitches can be moved up and down. Spiral rollers of different rotatable threads with a switching device that can be held at a position lower than the rising limit of the walking beam when selected and raised between rollers of different pitches, and groove of the walking beam. The pitch is the same as the multiple pitch of the shape and has a plurality of groove shapes, and at the position where the groove shape of the thread of the spiral roller coincides with the groove shape when descending, and the walking beam itself Alternatively, a groove shape changing lifter provided between the mounts, which is a separate body and is capable of rising to a position higher than the thread of the spiral roller and lower than the rising limit of the walking beam, and the spiral. The end face processing device is provided in front of the thrust of the circular cross section member placed on the roller in the direction of the component force of the circular cross section member. It is an apparatus for processing an end portion of a circular cross-section material having various diameters during transfer, which is characterized in that:

[Action]

According to the present invention, in the end face processing apparatus for a circular material having various diameters during transportation, a plurality of thin circular materials are simultaneously placed in parallel on a platform such as a skid rail, and a traverse walking beam (rechen) at the end portion thereof. , And the whole number is transferred at the same time by the movement of the walking beam.

Then, a spiral roller having the same pitch as the walking beam is selected, and it is raised and held at a position lower than the rising limit of the walking beam. Then, the spiral roller is rotated by the drive of the motor, and the circular cross-section members mounted between the screw threads are transferred while rolling. At this time, each of the circular cross-section members moves forward while rolling in a certain direction of the rotary grindstone by the thrust component of the thrust force of the spiral roller, contacts the stopper member, and contacts the outer peripheral surface of the rotary grindstone. , All of them are subjected to edge processing such as chamfering grinding at the same time. Then, the working beam is carried out to the next step.

Further, next, a circular cross-section material having a diameter larger than that of the circular cross-section material is formed on the roll gang as a mount at the same time as one of the grooves
Alternately, a number of straight lines are placed straight at the same time.

At this time, the lifter having a groove-shaped pitch twice that of the roll gang bite has been raised in advance, and the walking beam thereby acts only every other groove-shaped groove. Such a walking beam is actuated to ensure that every other circular member with a large diameter on the roll gang is scooped into the groove of the corresponding walking beam, placed, and laterally fed. It

Next, a spiral roller having the same pitch as that of the walking beam is selected in advance, and the spiral roller is raised, and while the walking beam descends between the threads of the spiral roller, the circular cross section material having the large diameter is formed. However, each is surely placed. As a result, the circular cross-section members are transferred while being rolled by the spiral roller that is driven by the motor in advance. As a result, the circular cross-section members with large diameters are advanced in the grindstone direction without contacting each other, and end portions such as chamfering are performed on the outer peripheral surface of the rotating grindstone while contacting the stopper member. .
Next, the walking beam is laterally fed while being placed in every other groove shape, and sent to the next step such as brush processing.

[Effect of device]

As described above, since the present invention is configured as described above, during the walking beam of the adjustment line,
An edge processing device such as a chamfering device is inserted, and a circular cross-section material of various diameters flowing in the conditioning line can be smoothly processed by utilizing the same walking beam.

By not using lifters (groove pitches corresponding to circular materials with different diameters), it is possible to use all of the groove shapes for fine circles, and by using this lifter, By arranging every other shape or every two shapes, it is possible to process the end portion of the circular cross-section material having a large diameter adapted thereto.

If there is no lifter for every other one, the thick round bar will not be surely placed one by one in the planned groove of the walking beam, such as every other round. Is 1
There is a risk that the end of the groove will be processed while it is placed in the groove on the front side and the groove on the rear side one behind the groove. Also, since the relationship between the movement of the walking beam and the stop position of the spiral roller is not always constant and may move slightly back and forth, even in this case, it is surely transferred in the planned groove of the walking beam. There can be things that cannot be done.

However, by providing this lifter, materials of various cross-sectional diameters can be reliably transferred into the groove of the planned walking beam, and chamfering etc. for each rod, whether thick or thin, is possible. The end part can be processed.

〔Example〕

Next, one embodiment of the present invention will be described with reference to the drawings.

1 and 2 are a plan view and a side view of an embodiment of the present invention. FIG. 3 is a front view for explaining a main part (lifter part).

Reference numeral 1 is a roll gang having a large number of groove shapes, and there is a motor for driving the roll gang.

Reference numeral 2 denotes a walking beam that extends parallel to the axis of the roll gang 1 at the end of the row of the roll gang 1 and that operates by drawing a substantially rectangular locus in a vertical cross section. Reference numeral 21 denotes a transverse feed, and the groove 21 has substantially the same groove shape as that of the roll gang 1. A plurality of driving devices are provided on the upper side of the walking beam 2 and drive the walking beam 2.

Reference numeral 3 is a spiral roller for a thick circle which is provided between the walking beams 2 and 2 so as to have an axis line parallel to the walking beam 2. Reference numeral 31 is a thread of the thick roller and has a pitch twice that of the roll gang 1. Reference numeral 32 is a thin round spiral roller provided in parallel with the thick circle, 33 is a thread thereof, and the pitch thereof is substantially the same as that of the roll gang 1. 34 is a seesaw type switching device for switching between a thick circle and a thin circle for raising. 35 is
A motor that drives the spiral rollers 3 and 32.

4 is a first lifter, which is above the walking beam 2 and in parallel with the walking beam 2.
Further, it is mounted so that it can be moved up and down in the longitudinal direction by the switching cylinder 42 and can be moved up and down, and the groove shape 41 provided on the upper part thereof is the thread of the spiral roller 3 for thick circles.
It is the same as the pitch of 31 and is twice the pitch of the groove shape of the roll gang 1.

Reference numeral 5 denotes a second lifter, which has a groove shape 51 having the same pitch as that of the first lifter 4 and which is attached to the walking beam 2 so as to be able to move up and down so as to perform the walking beam simultaneously with the beam 2. is there. This is for transferring from the portion of the spiral roller 3 and the walking beam 2 for supplying the processing material W to the grindstone 6 described later onto the spiral roll 3 of the portion for supplying the brush 8 described later.

Reference numeral 6 denotes a rotating cylindrical grindstone, which has an axial center line parallel to the roll gang 1 and the spiral rollers 3 and 32, and which has the thrust of the circular cross-section material W placed on the spiral roller 3 or 32. It is provided in front of the axial direction of the component W of the processed material W. Reference numeral 61 is a motor for driving the grindstone 6.

Reference numeral 7 denotes a stopper member, which is provided above the grindstone 6 substantially parallel to the axis of the grindstone 6.

Reference numeral 8 is a flat circular rotary brush, and the head end face portion 81 of the circular cross-section material W transferred by the spiral roller 3 or 32 is provided on the lower side of the processing flow of the grindstone 6 so that the head end surface portion 81 can come into contact therewith. There is a motor for driving the flat circular rotary brush 8.

Reference numeral 9 is a cylindrical thrusting roller for increasing the thrust force, which has a shaft center between the spiral rollers 3 and 3 and parallel to the shaft center of these rollers 3, and between the screw threads 31 and 31 thereof. The upper portion of the circular member W having a circular cross section placed on the upper portion abuts on the lower surface of the circular member W to give a forward force.

Next, the operation and effect of the above embodiment will be described. In the embodiment, the circular cross-section material W is a round bar steel material having a diameter of 19 to 120 mm, and an example in a refining treatment line at a steelmaking factory will be described. 16 ~
46mmφ is processed as a thin round material WA and 47-120mmφ is processed as a thick circular material WB.

First, a large number of thin circles WA are cold shears (not shown)
It is cut by, and is placed in each groove on the roll gang 1, and is moved straight to the right in FIG. 1 by the drive motor. Then, the thin round material WA abuts on the stopper 12 at the final end of the roll gang 1.

As a result, the walking beam 2 moves up, and the thin round members WA on the roll gang 1 are picked up one by one in the groove shapes 21, 21, respectively, and fed laterally, and then the walking beam 2 descends. .

As a result of this lowering, one screw is placed between the threads 33, 33 of the thin round spiral roller 32 that has been selected and raised and held in advance.

The group of the placed thin round materials WA rolls by the spiral rollers 32, 32 rotated by the motor 35 and also advances in the axial direction.

The group of the forward-advanced round members WA rolls while the head 81 thereof is in contact with the front stopper member 7. Therefore, the end face of the group of fine circles WA contacts the outer peripheral surface of the rotary grindstone 6 and is ground. As a result, burrs generated when cutting with the cold shear described above are ground and the end faces are cut into corners. As a result, when processing in the next process,
The handling of thin round material WA becomes easy.

Then, subsequently, still further, the spiral roller 32 continues the rolling and the advance in the axial direction of the group of thin round members WA.

A flat circular rotary brush 8 provided on the lower side of the grindstone 6 is driven by a motor 82.
Since the group of finely ground material WA that has been ground rolls while contacting the flat surface of the brush 8, the ground end surface is brush-polished.

This group of finely rounded materials, WA, is the spiral roller
Roll over 32 to the lower side.

Then, after the processing of the thin round material WA group is completed, the thick round material WB group is processed in the same manner as the thin round material WA group. In the following, only the points different from the thin round material WA will be described.

The switching cylinder 42 is urged to move forward to advance to the first
The lifter 4 is raised, and the groove shape of the wing beam 2 is changed every other groove.

Therefore, the thick round bar WB group is picked up from the roll gang 1 into the grooves 41 of the changed walking beam 2 one by one.

Further, the spiral roller is also switched in advance by the switching device 34 to the thick circle roller 3. Therefore, the thick round material WB group unloaded from the walking beam 2 is also transferred one by one between the screw threads 31, 31 of the pitch for thick round. As a result, the thick round material WB group when contacting the grindstone 6 surely contacts the grindstone 6 at a predetermined pitch and at an angle that is orthogonal to the axis of the grindstone 6, so that end face grinding is also possible. The end face of the plan will also be cut at the planned corner. That is, the thick head WB does not come into contact with the grindstone 6 in the side groove in the front groove in the traveling direction and in the rear groove in the rear portion,
In addition, one is adjacent to each of the grooves for fine circles, but on the other hand, in some cases, there is a gap of two or three and they are transferred to the spots, and the grindstone 6 is overloaded. , I no longer said that I could not grind well because it was too blank.

Further, the thick round material WB group processed by the grindstone 6 is polished by the brush 8. Also at this time, the second lifter 5 is raised and the spiral roller is also switched to the thicker 3 in advance. Therefore, as in the case of the thick round material WB group at the grindstone 6, every other one is transferred. Therefore, the brush polishing is performed smoothly as in the above.

As described above in detail, according to the above-described embodiment, the thick round material WB group and the thin round material WA group are sequentially flown, and the lifter and the spiral roller for each time are preselected. , By this, the fine round material is provided in all of the grooves for fine round, or
The thick round material is scooped into the thick round groove (every other thin round groove),
Or, since it is lowered, the end face can be processed without difficulty and evenly. Also, it is no longer necessary to manually make corrections. As a result, it became possible to perform end face machining without stagnation on the finishing line.

The present invention is not limited to the above-described embodiment, and can be added and modified as long as it does not violate the gist described in the claims of the invention. For example, instead of the roll gang 1, a skid rail, or Even if they are placed in a single stage on a fixed type such as a spiral roller or a movable type stand,
It can be processed in the same manner, and the same can be done by using Rechen instead of the walking beam, and the first and second lifters are also separately attached even if they are not attached to the walking beam. The same effect can be obtained even if the same exercise as the walking beam is performed, or if it is an up-and-down type in which every other one is placed when lowered to the walking beam.

In addition, the spiral roller, even in the case of a screw thread coexisting type of different pitch, has a long length, and the screw threads of the first half and the second half are reversed to advance the axial section of the circular material to be transferred. Since the directions are opposite, it is also within the scope of the present invention that the grindstone and the brush are not placed in one as in the above-mentioned embodiment, but are placed on both, and the head is ground and the rear end is ground and polished. It is what is done.
