Description

Technical Field

[0001] This utility model relates to the field of flying shear technology, specifically a short material conveying structure for a flying shear. Background Technology

[0002] In the field of sheet metal shearing, traditional flying shears have a separate rear belt from the blade holder, with the belt remaining stationary. When shearing short pieces less than 200mm in length, the sheared sheet metal is prone to falling into the gap between the flying shear and the belt, causing jamming or requiring additional processing, increasing costs and efficiency losses.

[0003] While existing technologies avoid collisions by increasing the distance between the belt and the cutter head, the presence of gaps limits the shearing capacity for short materials. No effective solution to this problem has yet been found in the industry; therefore, a new short material conveying structure for flying shears is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a short material conveying structure for a flying shear machine to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A short material feeding structure for a flying shear machine includes:

[0007] The upper tool holder and the lower tool holder are connected to gear one and gear two respectively via eccentric shaft one and eccentric shaft two;

[0008] The guide rail bracket is connected to the upper tool holder by bolts and is slidably connected to the lower tool holder by linear guide rail two.

[0009] The guide frame is fixed on the guide rail frame and has a groove inside;

[0010] The roller frame and rollers are slidably embedded in the grooves of the guide frame, and the roller frame is fixed to the belt support frame by a connecting plate;

[0011] The belt telescopic frame is hinged to the belt support frame by a pin, and the belt telescopic frame is equipped with belt conveyor shaft one and belt conveyor shaft five;

[0012] The belt fixing frame is slidably connected to the belt telescopic frame via a linear guide rail one. The belt fixing frame is equipped with belt shaft two, belt shaft three, and belt shaft four.

[0013] The belt is wrapped around belt conveyor shaft 1, belt conveyor shaft 2, belt conveyor shaft 3, belt conveyor shaft 4, and belt conveyor shaft 5. The belt telescopic frame moves horizontally back and forth with the rotation of the upper and lower tool holders, driving the belt to extend and retract synchronously.

[0014] Furthermore, a fixing block is welded onto the belt support frame to limit the range of movement of the pin.

[0015] Furthermore, the belt conveyor shaft one and belt conveyor shaft five are connected to the belt telescopic frame via bearings.

[0016] Furthermore, the belt is made of wear-resistant rubber and has anti-slip textures on its surface.

[0017] Furthermore, the groove of the guide frame is provided with a lubricating coating to reduce the sliding resistance of the rollers.

[0018] The beneficial effects of this utility model are:

[0019] In this invention, the dynamic linkage design between the blade holder and the belt completely eliminates the problem of short material falling due to fixed gaps in traditional equipment, filling the gap in short material handling technology for flying shear machines in China.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Please see Figures 1 to 7 In this embodiment of the utility model, a short material conveying structure for a flying shear machine includes:

[0033] The upper tool holder 1 and the lower tool holder 6 are connected to gear 3 and gear 22 respectively via eccentric shaft 1 2 and eccentric shaft 2 5;

[0034] The guide rail frame 7 is connected to the upper tool holder 1 by bolts and is slidably connected to the lower tool holder 6 by linear guide rail 23;

[0035] The guide frame 10 is fixed on the guide rail frame 7 and has a groove inside;

[0036] The roller frame 8 and the roller 9 are slidably embedded in the groove of the guide frame 10. The roller frame 8 is fixed to the belt support frame 12 by the connecting plate 11.

[0037] The belt telescopic frame 13 is hinged to the belt support frame 12 via a pin 24, and the belt telescopic frame 13 is equipped with belt conveyor shaft 17 and belt conveyor shaft 26.

[0038] The belt fixing frame 16 is slidably connected to the belt telescopic frame 13 via linear guide rail 14. The belt fixing frame 16 is equipped with belt conveyor shaft 2 18, belt conveyor shaft 3 19 and belt conveyor shaft 4 20.

[0039] The belt 21 is wrapped around the belt conveyor shaft 17, belt conveyor shaft 28, belt conveyor shaft 319, belt conveyor shaft 420, and belt conveyor shaft 526. The belt telescopic frame 13 moves horizontally back and forth with the rotation of the upper cutter holder 1 and the lower cutter holder 6, driving the belt 21 to extend and retract synchronously.

[0040] The belt support frame 12 is welded with a fixing block 25 to limit the movement range of the pin 24.

[0041] Among them, belt conveyor shaft 17 and belt conveyor shaft 26 are connected to belt telescopic frame 13 through bearings.

[0042] When using this utility model:

[0043] When the flying shear machine starts, the electric motor drives gear 3 and gear 22 to rotate synchronously with a 1:1 meshing ratio. Eccentric shafts 2 and 5 drive the upper blade holder 1 and lower blade holder 6 to perform periodic rotary motion, respectively. During this process, the guide rail frame 7 is rigidly connected to the upper blade holder 1 by bolts, and forms a sliding pair with the lower blade holder 6 through the linear guide rail 23, converting the vertical rotary motion of the upper blade holder into horizontal displacement.

[0044] The roller frame 8 is fixed to the guide rail frame 7 by bolts, and the roller 9 below it is embedded in the groove of the guide frame 10, converting vertical motion into horizontal thrust.

[0045] One end of the connecting plate 11 is fixed to the roller frame 8, and the other end is connected to the belt support frame 12 by bolts, thereby transmitting the horizontal thrust to the belt support frame 12.

[0046] The belt support frame 12 is slidably connected to the belt fixing frame 16 via linear guide rail 14 and hinged to the belt telescopic frame 13 via pin 24. When the tool holder rotates, the belt support frame 12 reciprocates in the horizontal direction, driving the belt telescopic frame 13 to extend and retract along the linear guide rail 14, causing the belt conveyor shaft 17 and belt conveyor shaft 26 fixed thereon to move synchronously. The belt 21 is wound around belt conveyor shaft 17, belt conveyor shaft 28, belt conveyor shaft 319, belt conveyor shaft 420, and belt conveyor shaft 26, forming a closed-loop transmission structure.

[0047] The displacement of the belt telescopic frame 13 is controlled by the clearance fit between the fixing block 25 and the pin 24, ensuring that the belt 21 always maintains dynamic contact with the tool holder, eliminating the 3-5mm fixing gap in traditional equipment.

[0048] Therefore, this utility model completely eliminates the problem of short material falling due to fixed gaps in traditional equipment by using the dynamic linkage design between the blade holder and the belt, filling the gap in short material handling technology for flying shear machines in China.

[0049] The belt 21 is made of wear-resistant rubber with anti-slip textures on its surface. These anti-slip textures improve the stability of the conveying process.

[0050] The guide frame 10 has a lubricating coating in its groove to reduce the sliding resistance of the roller 9.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
