Description

Technical Field

[0001] The invention relates to the technical field of straightening machine equipment, in particular to a split type cutting and straightening machine. Background Art

[0002] Straightening machine is also called wire straightening machine, wire straightening and cutting machine or wire straightening and cutting machine. Straightening machine is mainly used to process coiled iron wire, stainless steel wire, aluminum wire, cold drawn wire, plastic coated steel wire and other materials. It mainly includes wire feeding mechanism, straightening mechanism and cutting mechanism. The wire feeding mechanism feeds the coiled workpiece to be processed into the straightening mechanism, the straightening mechanism straightens the workpiece and feeds it into the cutting mechanism, and finally the cutting mechanism cuts the workpiece into a fixed length, so as to meet the production requirements, facilitate further processing of the workpiece and facilitate operation.

[0003] At present, straightening machines are generally integrated, with all mechanisms arranged on the same frame. This structure leaves too long tail material left after processing one roll, wasting raw materials. Therefore, people have developed a split straightening machine, which separates the cutting mechanism and sets it accordingly. For example, Chinese patent application number CN201120306095.1 discloses a split-type steel bar straightening and cutting machine. Although it solves the problem of steel bar bending caused by obstruction when passing through, in actual processing, the straightening mechanism always has friction on the workpiece to rotate when straightening. When there is a lot of workpiece left, the workpiece is wrapped around the material tray and constrained and will not rotate. However, when the workpiece is processed to only the tail material, since the tail material is not wrapped around the material tray and is not constrained, the tail material rotates, and the tail material and the blade in the cutting mechanism produce friction, which increases the wear rate, makes the blade no longer sharp, and reduces the service life; similarly, the tail material and the wire feeding wheel in the wire feeding mechanism will also produce friction, causing wear, increasing the gap between the wire feeding wheels, reducing friction, easy slipping, slow wire feeding efficiency, and reducing processing efficiency.

[0028] At both ends of the first guide rail 61, mounting plates 7 are respectively fixed. The two mounting plates 7 are respectively fixed to the first frame 1 and the second frame 2 by screws. Preferably, there are two first guide rails 61, and the two first guide rails 61 are arranged in parallel and at intervals, and the first guide rails 61 are all arranged parallel to the direction of workpiece movement. A sliding bearing 8 corresponding to the first guide rail 61 is fixed to the bottom of the carriage 62, and the sliding bearing 8 is sleeved on the first guide rail 61 to ensure the smooth movement of the carriage 62.

[0029] A guiding boss 621 is provided on the carriage 62, and the upper pressing plate 63 and the lower pressing plate 64 are respectively in sliding fit with the guiding boss 621. Step grooves 67 are respectively formed on the upper pressing plate 63 and the lower pressing plate 64, and the two step grooves 67 are correspondingly arranged and form a gap.

[0030] Specifically, limit pins 9 are respectively protruded on both sides of the upper pressing plate 63 and the lower pressing plate 64, and the limit pins 9 respectively abut against the side surfaces of the guiding boss 621 to ensure the smooth movement of the upper pressing plate 63 and the lower pressing plate 64 during movement and prevent them from sliding out of the carriage 62.

[0031] An adjusting device 68 is further provided on the carriage 62. The adjusting device 68 includes an adjusting screw 681 and a limit bolt 682.

When the oil cylinder 55 drives the movable knife 532 to move downward and completes a cutting action, the movable knife 532 returns to its original position under the elastic force of the fifth spring 58, thereby improving work efficiency.

The sensing rod 563 is movably arranged in the screw sleeve 564, and the front end of the sensing rod 563 passes through the limit sleeve 565 and is exposed outside the screw sleeve 564. The front end of the sensing rod 563 is arranged corresponding to the workpiece, and the rear end of the sensing rod 563 is arranged corresponding to the sensing switch 566.

[0049] The sensing switch 566 is electrically connected to the oil cylinder 55. When the workpiece hits the sensing rod 563, the sensing rod 563 overcomes the elastic force of the fourth spring 567 and slides in the screw sleeve 564 until the rear end of the sensing rod 563 hits the sensing switch 566.

[0050] Specifically, a motor for driving the straightening mechanism 4 and the wire feeding mechanism 3 on the first frame 1 is provided in the first frame 1, and the straightening mechanism 4 is driven by a pulley, and the corresponding driving wheel 321 is driven by a sprocket; a motor for driving the wire feeding mechanism 3 on the second frame 2 is also provided in the second frame 2, and the corresponding driving wheel 321 is also driven by a sprocket; a hydraulic control system and a pneumatic control system are also provided in the first frame 1 or the second frame 2.

[0051] The working principle of the present invention is as follows: the workpiece enters from the wire feeding mechanism 3 on the first frame 1, and the workpiece moves forward through the cooperation of the wire feeding wheel 32, and the workpiece enters the straightening mechanism 4, and passes through the stepped groove 67 after straightening. The clamping cylinder 65 works to clamp the workpiece. Since the workpiece always has a tendency to move forward under the action of the wire feeding mechanism 3 and the straightening mechanism 4, the slide 62 is driven to move toward the position of the second frame 2, until the slide 62 hits the travel switch on the second frame 2, the clamping cylinder 65 retracts, releases the workpiece, and the push cylinder 66 works to push the push rod 69, so that the slide 62 moves to the initial position of the first frame 1, until the slide 62 hits the travel switch on the first frame 1, the push cylinder 66 retracts, the clamping cylinder 65 works, and the workpiece is clamped again, thereby repeating the cycle, so that the workpiece keeps moving forward and is always in a clamped state. ; The workpiece continues to move forward, passes through the wire feeding mechanism 3 on the second frame 2, and moves into the cutting mechanism 5. The workpiece passes through the through hole 533. When the workpiece reaches the sensing rod 563, the sensing rod 563 overcomes the elastic force of the fourth spring 567 and slides in the screw sleeve 564 until the rear end of the sensing rod 563 reaches the sensing switch 566. The cylinder 55 starts to work, causing the movable knife 532 to move downward to cut the workpiece. At the same time, the workpiece is clamped with the cooperation of the movable knife 532 and the fixed knife 531, so that the slide 52 overcomes the elastic force of the third spring 54 and slides along the second guide rail 51. After the workpiece is cut off and falls, the cylinder 55 is reset, and the movable knife 532 returns to its original position under the elastic force of the fifth spring 58, the slide 52 returns to its original position under the elastic force of the third spring 54, and the sensing rod 563 returns to its original position under the elastic force of the fourth spring 567, and the next cutting action is continued.
