[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0024] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0027] Combined with Figure 1-4, an automatic hydraulic shearing machine for waste strips of the present embodiment is arranged at the waste strip outlet of the punch press, including a workbench 1, a shearing mechanism 2 and a blanking slope 3 are arranged on the workbench 1, the inclination angle of the blanking slope 3 is 10°, the shearing mechanism 2 is arranged between the punch press and the blanking slope 3, and the waste strips generated during punching are moved to the top of the blanking slope 3 through the shearing mechanism 2, and also includes a controller, which is electrically connected to the punch press and the shearing mechanism 2 respectively, and the controller controls the shearing frequency of the shearing mechanism 2 according to the punching frequency of the punch press. Specifically, the number of punching times of the punch press can be calculated according to the length of the strip cut and the feeding length of the punch press. The controller sets the number of punching times of the punch press. After the set number of punching times is reached, the punch press stops working and the shearing mechanism 2 starts working at the same time. After the shearing mechanism 2 cuts the strip, the working speed is completed within 2.5S, and the punch press automatically starts working again, avoiding the occurrence of quality problems and also solving the problem of waste cutting. For example, if the length of the waste strip after cutting needs to be 50 cm and the range of each punching is 10 cm, then cutting is performed once after five punchings.

[0028] As a preferred embodiment of the present utility model, the shearing mechanism 2 includes a hydraulic cylinder 21, an upper sliding knife body 22 and a lower fixed knife body 23. The upper sliding knife body 22 is arranged above the lower fixed knife body 23. The cutting edges of the upper sliding knife body 22 and the lower fixed knife body 23 are arranged facing each other. The lower fixed knife body 23 is fixedly connected to the workbench 1. The hydraulic cylinder 21 controls the upper sliding knife body 22 to move up and down relative to the lower fixed knife body 23, thereby realizing the cutting action of the waste strips.

[0029] As a preferred solution of the utility model, the upper sliding blade body 22 and the lower fixed blade body 23 have a width of 420 mm and are made of Cr12MoV, which can achieve the cutting of strips with a thickness of 4-8 mm, a material of 40Cr, and a width of ≤300 mm.

[0030] As a preferred solution of the utility model, the lower side of the material dropping slope 3 is a waste material dropping opening, and a waste material basket is provided below the waste material dropping opening. The waste materials fall from the waste material dropping opening into the waste material basket below for collection.

[0031] As a preferred embodiment of the utility model, a drop baffle 31 is provided at the waste material drop-off opening, and also includes a first driving member for controlling the movement of the drop baffle 31 to open and close the waste material drop-off opening. The first driving member can be an existing driving member such as a motor or a cylinder that can control the drop baffle 31 to leave the waste material drop-off opening. When the drop baffle 31 is located at the waste material drop-off opening, the waste material will slide along the drop slope 3 to the waste material drop-off opening and will abut against the drop baffle 31, so that the entire waste material will fall together, and the falling height and time will be consistent. Otherwise, it will be tilted when it falls into the waste basket, resulting in a messy placement of the waste basket.

[0032] As a preferred solution of the utility model, two pressure sensing structures 4 are provided on the side of the blanking baffle 31 close to the blanking slope 3. The two pressure sensing structures 4 are respectively provided at the two ends of the blanking baffle 31. The pressure sensing structure 4 is electrically connected to the first driving member 32. Only when the two pressure sensing structures 4 sense pressure, the driving member 32 is allowed to work to open the waste material drop opening to make the waste material fall. Otherwise, if only one pressure sensing structure 4 senses pressure, it means that the waste material is not both ends against the blanking baffle 31 at this time, and manual intervention is required to adjust the posture of the waste material to ensure that it falls into the waste basket in an orderly manner.

[0033] As a preferred solution of the utility model, the pressure sensing structure 4 includes a pressure sensor 41 and a pressure plate 42. The area of ​​the pressure plate 42 is larger than the force-bearing area of ​​the pressure sensor 41. The pressure sensor 41 is arranged between the blanking baffle 31 and the pressure plate 42. The pressure plate 42 replaces the pressure sensor 41 to contact the waste strip material, which disperses the force generated by the impact, thereby increasing the service life of the pressure sensor 41 and increasing the detection range of the pressure sensor 41. There is no need to set multiple pressure sensors 41 at the same end at the same time.

[0034] As a preferred solution of the utility model, a push plate 5 is provided on one side of the blanking slope 3 close to the shearing mechanism 2, and a second driving member for pushing the push plate 5 to move back and forth along the width direction of the blanking slope 3. The second driving member is an existing driving member such as a cylinder. When the posture of the waste strip material does not meet the requirements (only sensed by a pressure sensing structure 4), the push plate 5 moves to the side of the blanking baffle 31 away from the shearing mechanism 2 to push the waste strip material off the blanking slope 3, thereby reducing the frequency of manual intervention and will not affect the next shearing action.

[0035] As a preferred solution of the utility model, a pad is provided under the shearing mechanism 2, and a groove is provided on the pad for matching with the push plate 5. The shearing mechanism 2 is arranged at the upper end of the pad, and the rear end face of the pad is flush with the rear end face of the shearing mechanism 2. The push plate 5 is embedded in the groove when not in use, thereby preventing the waste strips from falling onto the push plate 5, resulting in the push plate 5 being unable to push the waste strips.

[0036] As a preferred solution of the utility model, the upper end of the push plate 5 is connected with a horizontally arranged limit plate 6, and the limit plate 6 is arranged vertically to the push plate 5, mainly to prevent the waste strips from going out of the upper end of the push plate 5 during the pushing process.

[0037] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
