As an embodiment of the present invention, the lower end surface of the steady state retainer 555 is provided with a lubrication pad 5520.

The working principle and the beneficial effects of the technical scheme are as follows: when the cutting machine is used for cutting materials, the cutting machine can meet the requirement for adjusting the placing angle of the cutting die according to production and manufacturing requirements. That is to say, based on the principle of not wasting materials, the placing angle of the cutting die can be adjusted within a certain range (0-90 degrees) in real time in the cutting process. In order to realize the real-time angle adjustment of the cutting die, an angle adjusting device 5 is additionally arranged between the hydraulic cylinder and the cutting die, wherein the intermediate transition frame 51 serves as an intermediate connecting member and serves as a rotary mounting member, the intermediate connecting member serves to connect the cutting die 34 to the hydraulic cylinder 32, and the rotary mounting member serves to provide mounting positions for the rotary adjusting gear 52 and the rotary adjusting motor 53. The rotation adjusting motor 53 drives the rotation adjusting gear 52 to rotate through gear engagement connection, so as to drive the cutting die 34 to rotate, and after the rotation reaches a specified angle, the rotation adjusting motor 53 stops operating, so that the angle adjusting action of the cutting die 34 can be completed.

However, in the daily production process, when a piece of material is cut, the angle of the cutting die 34 is often required to be adjusted for several times, and when the angle adjusting device 5 is used for adjustment, a more obvious problem exists: namely, when the cutting die 34 is rotated to a designated angle, the fixing of the cutting die 34 is achieved only by means of the first gear 54 and the stoppage of the rotation adjusting motor 53. Specifically, the cutting die 34 is inevitably subjected to a rotational force caused by an external force or material wrinkles during the downward pressing cutting process, so that the angle of the cutting die 34 is deviated, which may cause a defective product to be cut, and the effect of resisting the external force by merely stopping the rotation of the rotation adjusting motor 53 is not good. In order to overcome this drawback, a steady locking assembly 55 is additionally provided in the angle adjustment device 5, so that the cutting die 34 can be locked in a steady state after the angle adjustment is completed. The constant state locking assembly 55 has two states: the free state and the constant state locking state are separated, and the angle adjustment and the locking of the cutting die 34 are realized under the switching of the two states.

Separation free state: when the cutting die 34 finishes cutting and needs to be adjusted in angle, the constant state locking assembly 55 enters the separation free state from the previous constant state locking state. In this state switching, the telescopic cylinder 5514 is extended to drive the state switching cap 558 to deflect clockwise through the connecting rod 5513, and when the state switching cap 558 deflects, the contact post 5511 is driven to deflect clockwise, so that the front end of the contact post 5511 contacts the right side of the double-end state switching block 557, and accordingly, the pawl tooth surface 557a on the right side of the double-end state switching block 557 is in contact fit with the ratchet tooth surface 552 a. After the state switching cover 558 is deflected, the locking motor 554 rotates forward to drive the locking power ring 552 to rotate counterclockwise through the transmission belt 553. Because the locking power ring 552 and the constant-state retainer 555 are in meshing transmission connection through the ratchet tooth surface 552a and the pawl tooth surface 557a on the right side of the double-head state switching block 557, the constant-state retainer 555 rotates anticlockwise. When the steady state holder 555 rotates counterclockwise, the synchronizing shaft 5515 fixed to the lower end thereof rotates synchronously, and the spline nut 5516 in threaded fit with the synchronizing shaft 5515 slides downward under the restriction of the spline groove 5517, so that the annular steady state locking frame 5518 is in a free state, and the annular steady state locking frame 5518 does not limit the rotation adjusting gear 52 in this state. At this time, the constant locking assembly 55 is driven by the rotation adjusting motor 53 to perform the angular adjustment even if the separation free state is completely entered.

The constant locking state: the movement of each component in the constant locking state is opposite to the movement of each component in the separation free state, and the description is omitted. The spline nut 5516 slides upwards under the action of each component to tightly press the annular constant state locking frame 5518 on the locking housing 551, so that the rotary adjusting gear 52 is in constant state locking under the action of the constant state locking assembly 55, and the cutter die 34 is not fixed only by stopping the rotation of the rotary adjusting motor 53.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
