The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0015] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of this invention herein are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0017] Please refer to Figures 1 to 4 , a horizontal feeding mechanism for an open-close die cold heading machine provided by the present invention, includes a nail bridge 10 for receiving blank A transported by a lifting hopper, a horizontal feeding mechanism 20 for receiving blank A falling from the nail bridge 10, a pushing structure 30 for receiving the blank transported by the horizontal feeding mechanism 20 and pushing it above a die B, and an up-down feeding structure 40 for feeding the blank pushed by the pushing mechanism 30 into the die B. In this embodiment, the lifting hopper feeds the blanks into the nail bridge one by one. The blanks fall onto the horizontal feeding mechanism after passing through the nail bridge, and are fed step by step into the pushing mechanism by the horizontal feeding mechanism (onto the forming groove of the pushing plate, which will be elaborated in detail below), and then the blanks are fed into the die B by the up-down feeding structure.

[0018] In this embodiment, the nail bridge 10 includes two parallel side plates 11 and a baffle 12 located above the two side plates 11, so that the blank can slide down between the two side plates 11, and under the action of the baffle 12, the blank can be blocked from sliding out of the outside of the two side plates.

[0019] The horizontal feeding mechanism 20 includes a mounting base 21, an eccentric shaft mounting plate 22 fixed to the mounting base 21, two eccentric shafts 23 rotatably mounted at both ends of the eccentric shaft mounting plate 22, a chain assembly 24 for driving and connecting the two eccentric shafts 23, a motor 25 fixed to the mounting base 21 for driving the two eccentric shafts 23 to rotate, a fixed feeding bridge 26 fixed to the eccentric shaft mounting plate 22, two movable feeding bridges 27 respectively located on both sides of the feeding bridge 26, and a transition structure 28 arranged at the end of the fixed feeding bridge 26 for transitioning the blank to the pushing structure 30. The eccentric shaft 23 is connected to the bearing The seat 29 is in contact with or fixed to the two movable feeding bridges 27, and the two eccentric shafts 23 drive the two movable feeding bridges 27 to perform an upward arc offset relative to the fixed feeding bridge 26 and then reset, so that the blanks that fall into the fixed feeding bridge 26 can be gradually pushed forward by the two movable feeding bridges 27. It is worth mentioning that one of the eccentric shafts 23 is equipped with a pulley 231, and the motor shaft of the motor 25 is connected to the pulley 231 through a belt 251. Since the two eccentric shafts 23 are connected by a chain assembly 24, when the motor 25 rotates, it can simultaneously drive the two eccentric shafts 23 to rotate.

[0020] The transition structure 28 includes an inclined unloading bridge 281 docking with the fixed feeding bridge 26 and a pressure plate 282 fixed above the unloading bridge 281. The pressure plate 282 is fixed to the mounting base 21 through a fixed plate 283. The material enters the unloading bridge through the push of the movable feeding bridge 27, slides down through the unloading bridge to the corresponding position, and is prevented from flipping over by the pressure plate above.

[0021] It should be noted that both the fixed feeding bridge 26 and the movable feeding bridge 27 are provided with grooves D for receiving the blanks so that the materials can fall stably.

[0022] In this embodiment, the pushing structure 30 includes a pushing knife 31 located below the unloading bridge 281, a pressure plate 32 fixed on the fuselage C, a drag plate 33 movably inserted in the pressure plate 32 and connected to the pushing knife 31, and a swing rod mechanism 34 for pushing the drag plate 33 to move. The pushing knife 31 is provided with a forming groove 311 so that the fallen blank can be positioned.

[0023] The swing lever mechanism 34 is a conventional means in the art, including a transmission shaft, a swing lever connected to the transmission shaft, and the swing lever is movably connected to the carriage. It is driven by a motor to swing, and the carriage 33 is dragged back and forth by the swing mechanism 34 .

[0024] The up-and-down feeding structure 40 includes a support hollow plate 41, two guide rail pairs 42 mounted on the front side of the support hollow plate 41, a clamping slider 43 connected to the sliders of the two guide rail pairs 42, and a clamping clip 44 mounted on the clamping slider 43. The back of the clamping slider 43 is also connected to a power swing lever 45. The power swing lever 45 is fixed to the machine body C through a lever seat 451, and the power swing lever is connected to a rotating shaft or other mechanisms that can cause it to swing, so as to drive the swing lever to drive the clamping slider to move back and forth on the support hollow plate 41.

[0025] What the present invention aims to achieve is that the eccentric shaft of the horizontal feeding mechanism drives two movable feeding bridges to move relative to the fixed feeding bridge, so as to drive the blank on the fixed feeding bridge to gradually advance forward and be sent into the pushing knife of the pushing structure through the transition structure. Then, after the pushing knife advances, the blank is pushed into the mold through the up-and-down feeding structure. The present invention can stably feed the blank horizontally into the mold, effectively improve the production efficiency, and is simple to maintain and convenient to use.

[0026] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
