Existing flying shear machines often experience issues with waste material not being discharged during operation, affecting the cleanliness of the working environment and the normal operation of the equipment. Furthermore, they cannot quickly adjust mold types, are cumbersome to operate, and have low work efficiency. Therefore, we provide a flying shear mechanism for flying shear machines to solve the above problems. Utility Model Content

[0030] Example 1

[0031] Please see Figures 1 to 6 This utility model is a flying shear mechanism for a flying shear machine, including a base 100 and mounting plates 102 installed at both ends of its upper surface. External fixing plates 105 are installed at the front and rear ends of adjacent mounting plates 102. Slide seats 106 are installed at both ends of adjacent front and rear external fixing plates 105. An inner sliding assembly 200 is provided between adjacent front and rear external fixing plates 105. The inner sliding assembly 200 includes an inner upper plate 201 located directly above the base 100, and a first support plate 202 and a second support plate 203 installed on the side walls of the inner upper plate 201. An intermediate shaft 204 is installed through the lower part between the first support plate 202 and the second support plate 203.

[0032] Specifically, side plates 103 are installed at both the front and rear ends of adjacent mounting plates 102, and a servo motor 104 is installed in the middle of one side wall of the mounting plate 102; a reducer 104a is installed on the output shaft of the servo motor 104, and the bottom of the slide block 106 is slidably connected to the top of the mounting plate 102 via a transverse slide rail; the front and rear ends of the first support plate 202 and the second support plate 203 are slidably connected to the inner wall of the adjacent outer fixed plate 105 via a longitudinal slide rail, and the two ends of the outer wall of the intermediate shaft 204 are rotatably fitted with first bushings 204a; the first bushings 204a are bolted to the first support plate 202 and the second support plate 103. On the inner wall of 203, a first crank plate 205 is installed at one end of the intermediate shaft 204; the top of the outer wall of the first crank plate 205 is installed on the output shaft of the reducer 104a, and a second crank plate 206 is installed at the other end of the intermediate shaft 204; an auxiliary shaft 207 is installed at the top of the outer wall of the second crank plate 206, and the other end of the auxiliary shaft 207 is rotatably installed inside the second bushing 207a; the second bushing 207a is installed on the inner wall of the adjacent mounting plate 102 by bolts, and conical lubricating nozzles 204b are installed on the outer walls of both the first bushing 204a and the second bushing 207a.

[0033] Furthermore, the mounting plate 102, side plate 103, outer fixing plate 105 and slide block 106 are all provided in two sets. The servo motor 104, reducer 104a, mold, etc. are all existing technologies, so they will not be described in detail here. The first support plate 202 and the second support plate 203 are symmetrically arranged. The slide block 106 is slidably mounted on the top plate of the mounting plate 102. The first support plate 202 and the second support plate 203 are slidably mounted on the inner wall of the outer fixing plate 105.

[0034] The operation process of this embodiment is as follows: The power of the entire mechanism comes from the servo motor 104. The servo motor 104 drives the reducer 104a to rotate through the output shaft. The output shaft speed of the reducer 104a is reduced proportionally according to the reduction ratio. The output shaft of the reducer 104a drives the first crank plate 205 to rotate. The output shaft of the reducer 104a is connected to the first crank plate 205 by a key. At the same time, the first crank plate 205 is also connected to the intermediate shaft 204 by a key. The first crank plate 205 drives the inner sliding assembly 200. The intermediate shaft 204 rotates, causing it to move in a circular motion around the output shaft of the reducer 104a. The intermediate shaft 204 is connected to the inner sliding assembly 200 via cylindrical roller bearings. When the intermediate shaft 204 moves in a circular motion, the inner sliding assembly 200, limited by the transverse and longitudinal slide rails, makes a similar circular motion to the intermediate shaft 204. The complete work cycle for each punching or cutting is as follows: Assuming the inner sliding assembly 200 is at its highest point, the intermediate shaft 204 moves in a circular motion under the drive of the servo motor 104. The rotation of the pressure needle causes the inner sliding assembly 200 to descend as a whole. As it approaches the lowest point, the inner sliding assembly 200 begins to press against the upper end of the mold. Upon reaching the lowest point, it punches or cuts the keel. Once the intermediate shaft 204 exceeds the lowest point, it causes the inner sliding assembly 200 to rise as a whole, gradually reducing the pressure on the mold. Following the rotation of the servo motor 104, the inner sliding assembly 200 reaches the highest point again, forming a complete cycle. The crankshaft of this mechanism mainly consists of the first crank plate 205, the intermediate shaft 204, and the... The mechanism consists of two crank-rotor plates 206. To prevent material from getting stuck during punching or cutting, the tangential speed of the intermediate shaft 204 must be equal to the linear speed of the material during operation. Therefore, the crank radius must be adapted according to the linear speed. The flying cutter mechanism operates continuously during punching or cutting. To ensure good lubrication of the cylindrical roller bearings, the first bushing 204a and the second bushing 207a have holes on their sides that lead directly to the cylindrical roller bearings. A tapered lubricating nozzle 204b is installed on the outside for easy lubrication.

[0035] Example 2

[0036] Please see Figure 2 and Figure 4Based on Embodiment 1, but different from the first embodiment, a guide plate 101 and a mold plate 300 are provided. The bottom front and rear ends of the mold plate 300 are equipped with a discharge plate 301, which solves the problem that the waste generated by the flying punch and flying shear mechanism of the existing flying shear machine cannot be discharged during use, affecting the cleanliness of the working environment and the normal operation of the equipment. At the same time, it is impossible to quickly adjust the mold type, the operation is cumbersome, and the work efficiency is low.

[0037] Furthermore, both the feeding plate 301 and the guide plate 101 are provided in two sets. The feeding plate 301 and the guide plate 101 play a guiding role for the waste material and prevent the waste material from accumulating.

[0038] The operation process of this embodiment is as follows: The intermediate shaft 204 of this mechanism runs through both sides, and the blanking plate 301 is installed below the mold plate 300. A guide plate 101 is installed on each side below the blanking plate 301 to ensure that the waste material after punching is discharged from the opening of the base 100, so as to avoid the waste material accumulating on the surface of the base 100, affecting the cleanliness of the environment and the normal operation of the equipment. The mold used in this mechanism can be selected to install a punching mold or a cutting mold according to the purpose of use. The size and position of the threaded fixing hole and the pin hole of the two molds are the same, which makes it easy for the staff to quickly adjust and change the mold type. The operation is convenient and the work efficiency is high.
