Description

Technical Field

[0001] The utility model relates to the technical field of shearing tools, in particular to a shearing tool for a PU pipe. Background Art

[0003] PU tubes need to be cut into equal lengths during some production processes, and currently most of the cutting is done manually;

[0004] However, the existing manual cutting requires marking on the hose to be cut before cutting, and cutting one end before cutting the other end. This cutting method has low precision, high labor intensity, and is time-consuming and labor-intensive. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a cutting tool for PU tubes, which overcomes the deficiencies in the prior art and effectively solves the problem that manual cutting in the prior art requires marking on the hose to be cut before cutting, cutting one end before cutting the other end, and this cutting method has low precision, high manual labor intensity, and is time-consuming and labor-intensive.

[0008] The PU tube is inserted into the groove at the top of the fixing seat and one end of the PU tube is extended into the fixing frame. The top of the PU tube is abutted by two pressure rollers to provide a limit guide for the movement of the PU tube in the groove. The fixing seat is driven to move on the bottom plate by the first push rod motor to adjust the cutting length of the PU tube. The first servo motor drives the screw to rotate, and the rotating screw drives the movable block to move along the connecting frame toward the fixing frame. When the bottom ends of the two splints move into the fixing frame, the second servo motor drives the bidirectional screw to rotate, and the rotating bidirectional screw The rod drives the two clamps to move closer to each other and clamp the PU tube, and then the first servo motor drives the clamping mechanism to move away, thereby pulling the clamped PU tube out of the groove of the fixing seat. When the clamping mechanism drives the PU tube to move to the other end of the screw, the second push rod motor extends downward to drive the cutter to contact the bottom of the fixing frame, so as to cut off the PU tube extending from the groove. Then the second servo motor drives the two clamps to move away from each other to loosen the PU tube. The cut PU tube falls down through the drop chute to prevent too many PU tubes from piling up on the top of the bottom plate.

[0009] Preferably, a groove is formed on the top of the fixing seat, and the bottom of the fixing seat forms a sliding fit with the top of the base plate.

[0010] The PU tube is transported in the groove of the fixing seat, and the fixing seat is driven to move on the bottom plate by the first push rod motor, so that the cutting length of the PU tube can be adjusted.

[0011] Preferably, the bottom of the fixing frame is aligned with the bottom of the groove, and the bottom end of the clamping plate is aligned with the bottom of the fixing frame.

[0012] The second push rod motor extends downward to drive the cutter downward to contact the bottom of the fixed frame, so as to cut off the PU tube extending from the groove. The bottom of the clamping plate extends into the fixed frame, so as to clamp the cut PU tube.

[0013] Preferably, a material drop groove is provided on the top of the bottom plate, and the length of the material drop groove is the same as the length of the screw.

[0014] The provided drop chute allows the cut PU tube to fall downward, thereby preventing excessive PU tubes from piling up on the top of the bottom plate.

[0015] Preferably, a first servo motor is installed at one end of the connecting frame, and the output shaft of the first servo motor is connected and fixed to one end of the screw rod, and the movable block forms a sliding fit with the connecting frame.

[0016] The first servo motor drives the screw rod to rotate, and the rotating screw rod drives the movable block to move along the connecting frame, thereby driving the clamping mechanism to pull out the clamped PU tube.

[0017] Preferably, a second servo motor is installed on an outer wall of one side of the mounting plate, and the output shaft of the second servo motor is connected and fixed to one end of the bidirectional screw rod, and the clamping plate and the mounting plate form a sliding fit.

[0018] The second servo motor drives the bidirectional screw to rotate, and the rotating bidirectional screw drives the two clamping plates to move closer to or away from each other, thereby clamping or loosening the PU tube.

[0019] The beneficial effects of the utility model are:

[0020] The PU tube is inserted into the groove at the top of the fixing seat and one end of it extends into the fixing frame, and the fixing seat is driven to move on the bottom plate by the first push rod motor to adjust the cutting length of the PU tube. When the bottom ends of the two clamps are driven by the first servo motor to move into the fixing frame, the two clamps are brought close to each other by the second servo motor and clamp the PU tube. Then the clamped PU tube is pulled out of the groove of the fixing seat, and the PU tube extending from the groove is cut downward with the help of the cutter. Then the two clamps move away from each other to release the PU tube, and the cut PU tube falls downward through the blanking chute to prevent too many PU tubes from piling up on the top of the bottom plate. This effectively solves the problem that manual cutting in the prior art requires marking on the hose to be cut before cutting, and cutting one end before cutting the other end. This cutting method has low precision, high labor intensity, and is time-consuming and labor-intensive. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A groove is provided at the top of the fixing seat 4, and the bottom of the fixing seat 4 forms a sliding fit with the top of the bottom plate 1. The PU tube is transported in the groove of the fixing seat 4. The fixing seat 4 is driven to move on the bottom plate 1 by the first push rod motor 3, and the cutting length of the PU tube can be adjusted. The bottom of the fixing frame 7 is aligned with the bottom of the groove, and the bottom end of the clamping plate 19 is aligned with the bottom of the fixing frame 7. The second push rod motor 8 extends downward to drive the cutter 9 to contact the bottom of the fixing frame 7 downward, so as to cut off the PU tube extending from the groove. The bottom of the clamping plate 19 extends into the fixing frame 7, so as to clamp the cut PU tube. A blanking trough 10 is provided at the top of the bottom plate 1. The length of the blanking trough 10 is the same as the length of the screw 12.
