Problems solved by technology

[0004] However, in the actual operation process, the worker places the unstamped steel strip on the mold after one stamping, and at the same time needs to aim with the naked eye to control the stamping position of the steel strip, so as to realize the next stamping, resulting in low production efficiency. Low

Embodiment 1

[0036] Embodiment 1: a kind of feeding device for stamping machine, such as figure 1 As shown, it includes a vertically placed frame 1, and the frame 1 is a rectangular parallelepiped frame. The frame 1 is fixed on the workbench of the stamping machine by bolts, and is positioned at the front end of the workbench. Two sliding slots 11 with a rectangular cross section are opened on the side wall of the frame 1, and the sliding slots 11 are arranged along the vertical direction. A guide block 12 arranged as a cuboid is slidably connected in each chute 11 . The cylindrical second pressing roller 22 is rotatably connected to the guide block 12 so that the second pressing roller 22 is placed horizontally.

[0037] Such as figure 1 with image 3As shown, the screw rod 13 is rotatably connected to the frame 1 through bearings, the threaded part of the screw rod 13 is placed in the above-mentioned chute 11, and the screw rod 13 is placed vertically. A cylindrical drive pipe 14 is...

Embodiment 2

[0045] Embodiment 2: a kind of feeding device for stamping machine, such as Figure 5 As shown, the difference from Embodiment 1 is that the setting of the first thread 741 and the second thread 751 is omitted (see figure 1 ).

[0046] The crankshaft 8 is fixed on the adjusting rod 76, the first connecting rod 81 and the second connecting rod 82 are hinged on the crankshaft 8, the end of the first connecting rod 81 away from the crankshaft 8 is hinged with the first positioning block 74, and the second connecting rod One end of the rod 82 away from the crankshaft 8 is hinged to the second positioning block 75 .

[0047] When in use, the adjusting rod 76 is rotated to drive the crankshaft 8 to rotate, and through the pulling force of the first connecting rod 81 and the second connecting rod 82, the first positioning block 74 and the second positioning block 75 can be moved towards the direction of mutual approaching at the same time. Moving, at the same time, the guide groove...

Embodiment 3

[0048] Embodiment 3: a kind of feeding device for stamping machine, such as Image 6 As shown, the difference from Embodiment 1 is that the setting of the first thread 741 and the second thread 751 is omitted (see figure 1 ).

[0049] A first gear 91 is fixed on the adjusting rod 76, and a second gear 92 is rotatably connected to the frame 1, and the first gear 91 and the second gear 92 are meshed. A first rack 93 is fixed on the first positioning block 74, a second rack 94 is fixed on the second positioning block 75, the first gear 91 is meshed with the first rack 93, and the second gear 92 and the second gear 92 are engaged. Two tooth racks 94 mesh.

[0050] During use, the adjusting lever 76 is rotated, and the adjusting lever 76 drives the first gear 91 to rotate. At the same time, the first gear 91 drives the second gear 92 to rotate, the second gear 92 drives the second rack 94 to move, and the first gear 91 drives the second gear A rack 93 moves. Thus, the simultane...

Abstract

The invention discloses a feeding device for a punch. The feeding device comprises a frame fixed to a worktable. A first compression roller and a second compression roller, which abut against the upper and lower surfaces of a steel strip, respectively, are rotatably connected to the frame. A ratchet wheel is fixed to an end portion of the first compression roller. A drive sleeve is rotatably connected to the first compression roller. A ratchet is hinged to the inner wall of the drive sleeve, and the ratchet is connected to the drive sleeve by means of a first elastic part. A first connecting rod is fixed to an outer wall of the drive sleeve. A second connecting rod is hinged to the first connecting rod. One end, far away from the first connecting rod, of the second connecting rod is hinged to a flywheel. Thus, the purpose of improving the production efficiency is achieved.

Description

technical field [0001] The present invention relates to a punching machine, and more particularly, it relates to a feeding device for a punching machine. Background technique [0002] The punching machine is a kind of motor that drives the flywheel to rotate, and drives the crank linkage mechanism through the clutch and transmission gear to move the slider up and down, so that the punch on the slider exerts an impact on the steel belt and punches the steel belt. [0003] At present, in the process of manufacturing gaskets, when the existing stamping machine is stamping the steel strip, the worker places the steel strip on the workbench of the stamping machine, installs the mold on the workbench, and can press the steel strip by moving the punch down. The washer is punched out, and then the worker pushes the steel strip along the length direction to facilitate the next stamping of the punch. [0004] However, in the actual operation process, the worker places the unstamped s...
