DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0026] Please refer to Figures 1 to 6 , the longitudinal shearing machine tool withdrawal device, comprising a fixed platform 1, the fixed platform 1 is fixedly installed with a fixed end 2, the fixed platform 1 is slidably installed with a sliding end 3, the fixed end 2 is rotatably installed with an upper knife shaft 4 and a lower knife shaft 5, and the upper knife shaft 4 and the lower knife shaft 5 are installed with a washer 6 and a blade 7.

[0027] The upper knife shaft 4 and the lower knife shaft 5 should be installed with corresponding limiting devices (achieved by machine screws or other ways) at the edge position. Since it is prior art, no further description is given here.

[0028] Under normal circumstances, the two ends of the upper knife shaft 4 and the lower knife shaft 5 are respectively in contact with the fixed end 2 and the sliding end 3, and cutting activity is achieved by rotation. When it is necessary to replace or adjust the gasket 6 and the blade 7, the sliding end 3 is moved to smoothly leave a space for operation at the end of the upper knife shaft 4 and the lower knife shaft 5 in contact with the sliding end 3, so that the knife withdrawal and knife arrangement work can be smoothly carried out.

[0029] Since the movement of the sliding end 3 is prior art, no specific limitation is given here.

[0030] The fixed platform 1 is fixedly installed with a fixed plate 8, and the fixed plate 8 and the fixed platform 1 are slidably installed with a sliding frame 10. The fixed plate 8 is provided with a power mechanism, which can move the sliding frame 10, facilitating subsequent knife withdrawal and knife arrangement work.

[0031] The sliding frame 10 is slidably installed with two approaching plates 15, and the sliding frame 10 is internally provided with a driving clamping mechanism. The sliding frame 10 can make the two approaching plates 15 approach each other, thereby clamping the gasket 6 on the upper knife shaft 4 and the lower knife shaft 5. Then the sliding frame 10 moves to drive the gasket 6 and the blade 7 to move synchronously, thereby achieving the knife withdrawal or knife arrangement activity.

[0032] The approaching plate 15 is provided with an adjusting mechanism, which can simultaneously or separately move the gasket 6 and the blade 7 on the upper knife shaft 4 and the lower knife shaft 5 for adjustment and control, facilitating daily use.

[0033] The number of adjusting mechanisms is four, and the number of adjusting mechanisms on each approaching plate 15 is two. The two adjusting mechanisms at the same height together constitute a working group corresponding to the upper knife shaft 4 or the lower knife shaft 5.

[0034] The adjusting mechanism includes an internally threaded cylinder 22 fixedly installed on the approaching plate 15, and a rotating rod 17 threadedly rotatably installed on the internally threaded cylinder 22. The side of the rotating rod 17 away from the approaching plate 15 is fixedly installed with a rotating block 21, and the other side of the rotating rod 17 is fixedly installed with a contact pad 18.

[0035] The operator can rotate the rotating block 21 to make the rotating rod 17 rotate in the internally threaded cylinder 22, so that the rotating rod 17 can advance or retreat, and the contact pad 18 moves synchronously. The contact pad 18 has two states in total, one is extended, and the other is retracted. It is worth noting that during use, the two contact pads 18 on the same working group need to maintain the same state.

[0036] When the working group corresponding to the upper knife shaft 4 is in the extended state, and the working group corresponding to the lower knife shaft 5 is in the extended state, at this time, the movement of the sliding frame 10 can make the upper knife shaft 4 and the lower knife shaft 5 move synchronously with the gasket 6 and the blade 7, realize synchronous tool withdrawal or tool arrangement.

[0037] When the working group corresponding to the upper knife shaft 4 is in the extended state, and the working group corresponding to the lower knife shaft 5 is in the retracted state, at this time, the movement of the sliding frame 10 can only make the upper knife shaft 4 move synchronously with the gasket 6 and the blade 7, realize the separate tool withdrawal and tool arrangement of the upper knife shaft 4.

[0038] When the working group corresponding to the upper knife shaft 4 is in the retracted state, and the working group corresponding to the lower knife shaft 5 is in the extended state, at this time, the movement of the sliding frame 10 can only make the lower knife shaft 5 move synchronously with the gasket 6 and the blade 7, realize the separate tool withdrawal and tool arrangement of the lower knife shaft 5.

[0039] The power mechanism includes a driving motor 9, the driving motor 9 is installed on the fixed platform 1, the shaft output end of the driving motor 9 is fixedly installed with a lead screw 13, the lead screw 13 is threadedly installed with a lead screw nut 14, the lead screw nut 14 is fixedly connected with the sliding frame 10, and the lead screw 13 is rotatably installed on the fixed plate 8.

[0040] When the driving motor 9 starts, the lead screw 13 can rotate, and then the lead screw 13 drives the lead screw nut 14 to move forward or backward, and the movement of the sliding frame 10 can realize the tool withdrawal or tool arrangement activity in cooperation with the subsequent device.

[0041] The driving clamping mechanism includes a servo motor 16, the servo motor 16 is installed on the sliding frame 10, the shaft output end of the servo motor 16 is fixedly installed with a bidirectional threaded rod 19, the bidirectional threaded rod 19 is threadedly installed with two threaded sleeves 20, the two threaded sleeves 20 are respectively located on the bidirectional threaded rod 19 in different threaded directions, the threaded sleeve 20 is fixedly connected with the corresponding approaching plate 15, and the threaded sleeve 20 can only move translationally on the sliding frame 10 and cannot tilt.

[0042] When clamping is needed, the servo motor 16 starts to rotate, and then the two threaded sleeves 20 move close to each other, so that the two approaching plates 15 move close to each other, at this time, the extended contact pad 18 can smoothly contact and clamp the gasket 6, and the retracted contact pad 18 cannot contact the gasket 6, thereby realizing separate tool withdrawal and tool arrangement.

[0043] The rotating rod 17 is fixedly installed with two positioning rings 23, the thread on the rotating rod 17 is between the two positioning rings 23, and the diameters of the two positioning rings 23 are all greater than the diameter of the inner threaded cylinder 22.

[0044] The positioning rings 23 can limit the movable range of the rotating rod 17, and when different positioning rings 23 abut against different surfaces of the inner threaded cylinder 22 (so that the rotating rod 17 cannot continue to rotate), the contact pads 18 correspondingly extend and retract in two states.

[0045] When the center of the rotating rod 17 is in the same plane as the center of the corresponding upper blade shaft 4 or lower blade shaft 5, the clamping effect of the contact pads 18 on the gasket 6 in the same working group can be ensured, so that the translation of the gasket 6 is smoother.

[0046] The fixed platform 1 is fixedly installed with a placing cabinet 11, the inside of the placing cabinet 11 is provided with placing layers 12, which provide storage space for tools and accessories, and users only need to simply turn around to place or take activities, which is convenient to use, and multiple placing layers 12 make the tools and accessories orderly classified storage, which is convenient to find and manage.

[0047] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
