Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a strip edge processing device.

[0002]

[Prior Art]

 When a wide strip steel plate is made into a narrow strip steel plate by a slitter, a flat grindstone or a cutting tool has been conventionally used as a device for removing the edge burrs.

[0003]

[Problems to be solved by the device]

 However, when the material width changes, it takes time to adjust the position. Moreover, it was not possible to cope with meandering of the strip steel plate or local unevenness.

The present invention solves the above-mentioned problems and provides an edge processing device for a strip that can easily cope with a change in the width of the strip and can immediately deal with meandering of the strip and local unevenness. The porpose is to do.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned subject, the composition of the present invention is as follows. In the first configuration, a guide bar is provided on a fixed base via a bracket so as to extend in a direction perpendicular to the passing plate, and a pair of left and right nut members are slidably engaged with the guide bar so as to move toward and away from each other. A feed screw rod extends in the direction perpendicular to the threaded plate and is screwed into these nut members, and both ends of the feed screw rod pass through the through holes of the bracket and are prevented from coming off. That is, the processing roller is installed.

The second configuration is that in addition to the first configuration, a pair of pinch rolls is provided on the upstream side and / or the downstream side in the sheet passing direction with the pair of processing rollers interposed therebetween.

The third configuration is that the entire first configuration is taken as one set, and a plurality of these sets are arranged in parallel in the sheet passing direction. The fourth configuration is the first or second or third configuration. In addition, in the processing roller, two annular bodies having chamfered outer peripheral corners are concentrically and removably coupled.

A fifth configuration is that, in addition to the first, second, third, or fourth configuration, the processing roller is made of wear-resistant metal.

[0009]

[Action]

 Rotate the feed screw rod and slide the nut member to sandwich the edge of the strip steel plate between the circumferential grooves of the processing roller. In this state, the strip steel plate is fed from the coil and continuously fed. The processing roller rotates freely accordingly. The burrs on the edges of the strip steel plate are broken or crushed by the circumferential groove of the processing roller to remove the burrs.

If there is meandering of the strip steel plate or local unevenness of the edge, the processing roller support unit is integrated with the nut member and the feed screw rod and slides left and right along the guide bar, which is impossible. Power does not work.

In the pinch roll portion, the upper and lower rolls freely rotate as the strip steel plate advances, and the strip steel plate is smoothly fed by the gravity of the upper roll without being bent vertically.

【Example】

 An embodiment of the present invention will be described below based on an embodiment shown in the drawings.

In FIGS. 1, 2, and 3, the strip plate A passes in the front-rear direction (hereinafter referred to as the sheet passing direction) as indicated by the arrow P. Two guide bars 3 are provided on the fixed base 1 via a bracket 2 so as to be spaced apart in the sheet passing direction and extend in a direction perpendicular to the sheet passing direction (hereinafter referred to as a sheet passing direction). A pair of rectangular parallelepiped block-shaped nut members 4 on the left and right (in the direction perpendicular to the plate) are slidably engaged between the guide bars 3 and 3 so as to move toward and away from each other, and are prevented from rotating.

A feed screw rod 5 extends in a direction perpendicular to the plate passing through these nut members 4, and is screwed with screw portions 5a and 5b which are opposite to each other. The vicinity of both ends of the feed screw rod 5 penetrates the interchange hole 2a of the bracket 2, and a handle 7 is fixed to one end (left end) and a stopper 8 is fixed to the other end (right end). As a result, the feed screw rod 5 and the nut member 4 are integrated with each other, and can be slidable between the brackets 2 and 2 along the guide bars 3 and 3 in the direction perpendicular to the passing plate.

On the upper surfaces of the nut members 4 and 4, processing roller supporting portions 10 and 10 having a pair of left and right processing rollers 14 and 14 are installed. That is, a rectangular annular mounting frame 11 is fixed to the upper surface of the nut member 4, a roller shaft 12 consisting of bolts vertically penetrating the mounting frame is inserted from the top to the bottom, and screwed with a screw portion at the lower end. To be done. A processing roller 14 having a V-shaped circumferential groove 14a is rotatably fitted into the roller shaft via a bearing 13. In the processing roller 14, two ring-shaped main bodies 14b 1 made of high hardness tool steel are sandwiched between upper and lower sleeves 14c and 14d, and are concentrically coupled by a set screw 14e. The outer peripheral corners of the roller body 14b are chamfered.

A pair of pinch rolls 20 and 20 are provided on the upstream side and the downstream side in the sheet passing direction with the pair of processing roller support portions 10 and 10 interposed therebetween. That is, in FIGS. 3 and 4, the freely rotating lower roll 22 is supported by the lower bracket 21, the freely rotating upper roll 25 is supported by the upper bracket 23, and the two bolts 25 erected on the lower bracket 21 are erected on the upper bracket. 23 is penetrated through, and a pressing plate 26 penetrates near the upper ends of these bolts 25, 25, and is fixed by upper and lower nuts 27, 28. Further, the pressing screw 29 penetrates from the top to the bottom in the middle portion of the pressing plate to press the upper surface of the upper bracket 23.

The above-mentioned whole is taken as one set, and these three sets are arranged in parallel in the sheet passing direction.

The operation state will be described above. 1 and 2, according to the width of the strip steel plate A, the handle 7 is rotated, the feed screw rod 5 is rotated, and the nut members 4 and 4 are slid so that the edge of the strip steel plate A is the circumference of the processing roller 14. Insert it between the grooves. In this state, the strip steel plate A is fed from the coil and continuously fed. The processing roller 14 rotates freely accordingly. The edge burrs of the steel strip A are bent or crushed by the circumferential groove of the processing roller 14 to remove the burrs.

If there is meandering of the strip steel plate A or local unevenness of the edge, the processing roller support portion 10 becomes integral with the nut member 4 and the feed screw rod 5 and slides left and right along the guide bar 3. Because it moves, it does not work with undue force.

In the pinch rolls 20 and 20, the upper and lower rolls 24 and 22 freely rotate as the strip steel plate A advances, and the strip steel plate A is vertically moved by the pressing force of the cap screw 29 and the gravity of the upper roll 24. It is sent smoothly without bending.

The processing roller may be an integral member or a circular grindstone.

The present invention is not limited to the above-described embodiments and embodiments, and includes various modifications without departing from the spirit and scope of the utility model registration request.

[0023]

[Effect of the device]

 According to the first configuration of the present invention, even if the width of the strip changes, the interval between the processing rollers can be easily adjusted in a short time, and even if the strip has meandering or local unevenness, an unreasonable force acts. I don't get tired.

With the second configuration, in addition to the effect of the first configuration, even if the vertical undulation phenomenon of the strip occurs, the work can be performed without any trouble.

With the third configuration, it is possible to uniformly process both edge portions.

According to the fourth configuration, even if the processing roller body is worn, it can be reused as a new one by replacing the two parts upside down.

With the fifth configuration, the processing roller has excellent wear resistance and withstands long-term use.
