Description

Technical Field

[0001] This utility model belongs to the field of gantry punch press technology, and relates to a feeding mechanism for a high-speed crankshaft gantry punch press. Background Technology

[0002] In traditional crankshaft gantry press machining, synchronizing the feeder and the press often faces numerous challenges. Previously, a common method relied on a complex gearbox structure for power transmission and synchronization. This approach not only resulted in a cumbersome overall transmission structure and complex installation process, requiring significant time and effort from professionals for debugging and installation, but also led to wear and tear on the numerous meshing gears within the gearbox over long-term use. This reduced transmission accuracy, affected feeding precision, and consequently negatively impacted product quality.

[0003] Meanwhile, the complex gearbox structure increases the processing cost of the equipment, with relatively high costs for both initial manufacturing and subsequent maintenance and replacement of parts. Furthermore, traditional feeding methods struggle to achieve precise step-by-step feeding, resulting in poor material fixation during punching and a tendency for displacement, severely hindering production efficiency.

[0034] Please see Figures 1-8 In this embodiment of the present invention, a feeding mechanism for a high-speed crankshaft gantry punch press includes: a feeder body 3 disposed on the crankshaft gantry punch press 1 and a transmission system 2, wherein the transmission system 2 achieves the effect of synchronous operation between the feeder and the crankshaft gantry punch press 1 during processing.

[0035] The transmission system 2 includes: a drive wheel 21, a transmission wheel 23, a power shaft 25, a transmission bevel gear 24, and a driven bevel gear 26, all aligned with the crankshaft axis of the crankshaft gantry punch press 1.

[0036] The drive wheel 21 and the transmission wheel 23 are connected by a belt. The transmission wheel 23 and the transmission cone are both mounted on the power shaft 25. The transmission cone tooth 24 and the driven cone tooth 26 are vertically distributed. The driven cone tooth 26 is mounted on the drive shaft of the feeder body 3. Thus, a transmission system 2 is formed between the drive wheel 21 and the driven cone tooth 26.

[0037] In this transmission system 2, the drive wheel 21, transmission wheel 23 and power shaft 25 are in the same axial direction as the crankshaft of the crankshaft gantry punch press 1. The drive wheel 21 is coaxially arranged with the crankshaft of the crankshaft gantry punch press 1, thereby achieving the effect of synchronous and coordinated feeding of the feeder body 3 when the crankshaft gantry punch press 1 is working.

[0038] Furthermore, the feeder body 3 consists of a feeding unit 5 and feeding rails 4 and 6 located at the front and rear ends of the feeding unit 5.

[0039] During processing, the sheet material to be processed is fed into the feed rail 4 and guided by the feed rail 4; while the feeding rail 6 extends towards the processing position of the punch press to guide the feeding; and the feeding unit 5 serves as the driving unit for feeding, and is synchronized with the crankshaft gantry punch press 1 through the transmission system 2.

[0040] The feeding unit 5 includes a camshaft 9, a feeding clamping group 7, and a processing clamping group 8. The camshaft 9 is the drive shaft of the feeder body 3, and the driven bevel gear 26 is mounted on the camshaft 9.

[0041] The camshaft 9 is connected to the feeding clamping group 7 and the processing clamping group 8 for transmission. During processing, the camshaft 9 drives the feeding clamping group 7 to feed the sheet material by clamping. During punching, the processing clamping group 8 is used to fix the material during processing, achieving a step-by-step feeding processing effect.

[0042] Furthermore, the feeding clamping assembly 7 includes: a feeding clamp 71, a feeding mechanism for driving the feeding clamp 71 to move back and forth, and a clamping mechanism for clamping and opening / closing.

[0043] The feeding mechanism includes a driven base 75 and a driven turntable 77 mounted on the driven base 75. The driven turntable 77 is provided with a driven roller 76 that is in drive cooperation with the camshaft 9. During the rotation of the camshaft 9, the driven roller 76 can drive the driven turntable 77 to rotate and reset in a cycle.

[0044] A swing block 710 is mounted on the driven turntable 77. One end of the swing block 710 extends to the lower end of the feeding clamp 71, and a connecting block 79 is mounted on the swing block 710 at this position. The lower end of the feeding clamp 71 is formed with a guide groove for the connecting block 79 to be embedded. When the driven turntable 77 rotates, the swing block 710 swings along the rotation direction of the driven turntable 77, forcing the connecting block 79 to slide continuously in the guide groove. Through the principle of the crank-slider mechanism, the swing of the swing block 710 is converted into the linear movement of the feeding clamp 71 in a specific direction, realizing the feeding action. When the driven turntable 77 resets, the swing block 710 also resets synchronously, causing the feeding clamp 71 to return to the initial position. In order to improve the stability of the sliding of the connecting block 79, a sliding guide shaft 78 is also provided in the guide groove along its length. The connecting block 79 is nested on the sliding guide shaft 78, and the sliding guide shaft 78 realizes the guiding work during the sliding process.

[0045] The clamping mechanism includes: a first cam block 711 and a second cam block 714 disposed at the front and rear ends of the driven base 75, and a clamping pull rod 712 disposed between the first cam block 711 and the second cam block 714;

[0046] The middle sections of the first cam block 711 and the second cam block 714 are fixed by a rotating shaft. The upper ends of the first cam block 711 and the second cam block 714 are hinged to both ends of the clamping pull rod 712. The lower end of the first cam block 711 is driven by the camshaft 9.

[0047] The clamping rod 712 passes through the feeding clamp seat 71, and the feeding clamp seat 71 is provided with a clamping slider 713 that can move up and down in the feeding clamp seat 71. The clamping slider 713 is fitted onto the clamping rod 712.

[0048] The feeding clamp 71 is provided with a fixed upper clamping block 74 and a movable lower clamping block 72; the upper end of the clamping slider 713 extends out and connects to the movable lower clamping block 72; during operation, the camshaft 9 rotates to push the first cam block 711 to swing around the rotating shaft, which drives the second cam block 714 fixed thereto to move synchronously, causing the clamping pull rod 712 to move and change its angle, and through the clamping pull rod 712, the clamping slider 713 in the feeding clamp 71 moves up and down, and the operation is carried out by the opening and closing of the fixed upper clamping block 74 and the movable lower clamping block 72.

[0049] In actual processing, the feeding mechanism and the clamping mechanism work together. First, the clamping mechanism drives the fixed upper clamping block 74 and the movable lower clamping block 72 to clamp the sheet material. Then, the feeding mechanism drives the feeding clamp seat 71 to be fed forward. After that, the clamping mechanism releases the clamping and the feeding mechanism drives the reset, completing one feeding action. This process is repeated to achieve step-by-step sheet material feeding.

[0050] Furthermore, the feeding mechanism also includes two sets of parallel feeding guide rails 73, with the two ends of the feeding clamp 71 nested on the feeding guide rails 73; the feeding guide rails 73 are used to guide the feeding process.

[0051] Furthermore, the processing clamping assembly 8 includes: a fixed upper clamping seat 81, a movable lower clamping seat 82, and a third cam block 83; the middle section of the third cam block 83 is fixed by a rotating shaft, one end is connected to the movable lower clamping seat 82, and the other end is driven by the camshaft 9; during processing, the camshaft 9 drives the movable lower clamping seat 82 to rise through the third cam block 83, thereby achieving the clamping of the sheet material.

[0052] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
