Description

Automatic positioning feeding cutting machine

Technical Field

The invention relates to the technical field of laser welding, in particular to an automatic positioning feeding cutting machine.

Background

In the cold rolling continuous production process, in order to form continuous strip steel rolling, the very important point is that the tail end of a forward plate material and the head of a subsequent plate material are welded into a whole, before laser welding, the subsequent plate material is positioned by a positioning device so as to align the front end of the subsequent plate material with the tail end of the forward plate material, and then the front end of the subsequent plate material is transversely cut, so that opposite edges are flattened, and a better welding effect is achieved; and finally, the head of the subsequent plate is sent into a welding device through a transfer device. The transfer device is mainly used for pressing the plate on the material supporting arm through the constant pressure mechanism and then pulling the plate to advance towards the welding device. However, when the sheet is pulled to advance towards the welding device, in order to enable the front end of the subsequent sheet to be connected with the welding device and the material supporting support arm not to interfere with the welding device, the front end of the sheet exceeds the front end of the material supporting support arm, so that the front end of the sheet is bent downwards due to no support, the problem of shell blocking easily occurs when the front end of the sheet is connected with the welding device, namely, the sheet interferes with parts of the welding device, and the normal transmission path of the sheet is changed.

When the device works, a plate material is firstly transited to the supporting support arm c4 from the positioning device until the plate material is completely pressed on the supporting strip c72 and the supporting support arm c4, and at the moment, the front end part of the plate material is supported by the supporting strip c72, as shown in fig. 5, so that the front end part of the plate material is prevented from bending downwards under the action of gravity, and the front end part of the plate material is ensured to be always kept in a horizontally unfolded state in the transferring process; then, the constant pressure mechanism c5 compresses the plate on the supporting arm c4, and finally the traction mechanism c3 drives the sliding frame c2 to enable the plate to advance towards the welding device.

In order to control the avoidance of the carrier strip c72, as shown in fig. 4 and 6, a first travel switch c81, a second travel switch c82, a third travel switch c83 and a fourth travel switch c84 are sequentially arranged on the frame a from back to front; the first travel switch c81, the second travel switch c82, the third travel switch c83 and the fourth travel switch c84 are all electrically connected with the control system, a front trigger piece c85 and a rear trigger piece c86 for triggering the travel switch are arranged on the carriage c2, the front trigger piece c85 is installed on the front end face of the carriage c2, and the rear trigger piece c86 is installed on the rear end face of the carriage c 2. In the initial state, the rear trigger piece c86 triggers the first travel switch c81, which indicates that the carriage c2 is located at the initial position; under the drive of the traction mechanism c3, the carriage c2 advances towards the direction of the plate cutting module, when the second travel switch c82 is triggered by the front trigger piece c85, the plate is indicated to move to the leveling cutting area, the second travel switch c82 feeds back a signal to the control system, the control system controls the traction mechanism to stop acting, but at the moment, the supporting strip c72 is in an extending state, and the plate cutting module cuts and levels the front end of the plate; then the front trigger piece c85 triggers the third travel switch c83, which indicates that the supporting strip c72 is very close to the welding device, the third travel switch c83 feeds back a signal to the control system, the control system controls the avoiding cylinder c73, the avoiding cylinder c73 drives the supporting strip c72 to retract to let, the collision between the supporting strip c72 and the welding device in the continuous advancing process of the sliding frame c2 is avoided, meanwhile, the sliding frame c2 continues to advance, the plate is smoothly and horizontally fed into the welding device, so that the problem of shell blocking when the front end of the plate is connected with the welding device is avoided, the current trigger piece triggers the fourth travel switch c84, which indicates that the plate is moved in place, the welding device welds the head of the plate and the tail of the plate at the downstream, and after the welding is completed, the constant pressure mechanism c5 loosens the plate; then the traction mechanism c3 drives the sliding frame c2 to move backwards for resetting, although the rear trigger piece c86 triggers the third travel switch c83, the supporting strip c72 is in a backward retracted state and cannot act, then the rear trigger piece c86 triggers the second travel switch c82, and the second travel switch c82 feeds back a signal to the control system, so that the avoidance cylinder c73 drives the supporting strip c72 to extend forwards again; when the rear trigger piece c86 triggers the first travel switch c81, the carriage c2 is reset to the home position.

In this embodiment, the guide seats c74 are provided with two linear bearing seats, and the guide rod c75 is a cylindrical shaft and penetrates through the two guide seats c74 laterally. The two linear bearing seats are arranged to share the downward pressure of the guide rod, so that the guide rod and the supporting strip are better supported, the guide rod and the linear bearing seats are matched to slide, and the guide rod is ensured to slide transversely and smoothly.

Preferably, the material supporting support arm c4 is formed by processing square tubes, so that purchasing and processing are facilitated, and the manufacturing cost is low. The top surfaces of the supporting arms form smooth supporting surfaces, and the plate materials are flattened on the supporting surfaces of the supporting arms; the bottom of the front end part of the supporting arm c4 is provided with a notch c41 to make the whole supporting arm be in shapeThe side of the support arm c4 is provided with a plurality of mounting holes, and a worker can put the screw into the support arm through the notch c41 and is matched with the mounting holes to assemble.

In order to ensure smooth movement of the carriage c2, a guide rail a4 extending in the front-rear direction is arranged on each first square tube a1, and the bottom of the carriage c2 is slidably connected with the guide rail a4 through a sliding block a 5.

Further, two groups of limiting assemblies c9 for limiting the forward and backward travel of the carriage c2 are arranged on the frame; each group of limiting assemblies c9 comprises a limiting seat c91, a hydraulic buffer c92 arranged on the limiting seat c91 and a limiting adjusting screw c93 arranged on the limiting seat c 91. When the carriage c2 is about to be in place, the carriage c2 is firstly contacted with the hydraulic buffer c92, the hydraulic buffer c92 absorbs moving inertial impact, the carriage c2 is decelerated and then abuts against the end part of the limit adjusting screw c93, the final stop position of the carriage c2 can be adjusted by screwing the limit adjusting screw c93, and the effects of adjusting the transfer distance of the plate material and the initial position of the carriage c2 are achieved.

In this embodiment, the traction mechanism c3 drives the carriage to move back and forth by adopting a transmission mode of a synchronous belt, and certainly, the carriage can also be driven to move by adopting a transmission mode of a chain transmission, a belt transmission or a linear module.

Further, the carriage c2 is provided with a liftout roller c61 located upstream of the stock supporting arm and a lift driving mechanism for driving the liftout roller to move up and down. The jacking rollers c61 extend transversely, the jacking driving mechanism comprises two jacking air cylinders c62 which are arranged upwards, the output ends of the two jacking air cylinders c62 are respectively connected with two ends of the jacking rollers c61, the roller ends of the jacking rollers c61 are fixed on the jacking air cylinders c62 through locking screws, and the jacking air cylinders c62 are fixed on the sliding frame c2 through mounting supports. In the initial state, the height of the ejector roller c61 is flush with the height of the carrier arm c 4. After the liftout cylinder c62 drives the liftout roller c61 to complete the up-down reciprocating motion within the set time, the liftout cylinder c62 enables the liftout roller c61 to maintain the liftout state, that is, the height of the liftout roller c61 is higher than that of the supporting arm c4, by means of the arrangement, the height of the plate positioned between the plate positioning module b and the supporting arm c4 can be improved to the greatest extent, and the influence on the product quality caused by the fact that the plate at the part bends downwards due to gravity and rubs with the corners of the sliding frame c2 in the transferring process is avoided. After the constant pressure mechanism c5 clamps the plate, the ejection cylinder c62 drives the ejection roller c61 to reset to the initial position. It should be understood that the control system controls the action time of the jacking driving mechanism, and can be realized by setting the existing control program.

In practical application, the height of the material supporting roller B2 is slightly higher than the top surface of the material supporting square tube B131, and the gap between the material supporting roller B2 and the groove wall of the U-shaped groove B133 is extremely narrow, so that the front edge of the plate material can smoothly fall onto the top surface of the material supporting square tube B131 after leaving the material supporting roller B2, and the plate material cannot be blocked into the gap between the material supporting roller B2 and the groove wall of the U-shaped groove B133 to form interference, so that the problem of shell blockage of the plate material in the positioning process is avoided.

When searching for edges, the material pulling driving device brings a movable grip b42 on the material pulling sliding seat b41 to move towards the side edge of the plate material; the pulling slide b41 is slidably connected with the guiding connecting rod b12, when the first edge searching sensing assembly b7 senses the side edge of the plate, the movable gripper b42 clamps the plate, and the movable gripper b42 on the pulling slide b41 pulls the side edge of the plate to move towards the positioning flange assembly b3 under the traction of the pulling driving device.

In this embodiment, referring to fig. 16, the movable gripper b42 includes a base b421 fixed on the pulling slide b41, a swinging base b422 rotatably disposed on the base b421, and a gripping cylinder b423 disposed vertically downward on the swinging base b 422; the output end of the grabbing cylinder b423 is provided with a first clamping block b424, and the swinging seat b422 is fixedly provided with a second clamping block b425 matched with the first clamping block b 424; the first edge finding sensing component is arranged on the swinging seat b 422. In the initial state, the first gripper block b424 and the second gripper block b425 on the movable grip b42 are separated from each other to form a grip opening.

When the first edge finding sensing assembly b7 senses the plate d, the movable gripper b42 is indicated to find the edge successfully, the clamping opening is very close to the side edge of the plate, the material pulling driving device continuously drives the movable gripper b42 to move towards the plate according to a set control program, so that the side edge of the plate stretches into the clamping opening and the edge of the plate abuts against the swinging seat b422, then the material grabbing cylinder b423 drives the first clamping block b424 to act, the first clamping block b424 and the second clamping block b425 clamp the plate together smoothly, at the moment, the extending direction of the side edge of the plate is parallel to the length extending direction of the first clamping block b424, and the plate does not drive the swinging seat b422 to swing.
