Summary of the invention
The object of the present invention is to provide a kind of aluminium strip leftover pieces rolling-up mechanism, can automatically collect sheet metal strip, the particularly aluminium strip leftover pieces after punching press.
Aluminium strip leftover pieces rolling-up mechanism of the present invention, comprise unidirectional intermittent drive mechanism, pedestal, Scroll and active, driven deflector roll, initiatively, driven deflector roll is arranged on pedestal up and down abreast, can be with respect to pedestal around its axis rotation, an end of the roll shaft of active deflector roll and driven deflector roll be fixed with respectively driving gear and with the driven gear of this driving gear engagement, be fixed with driven wheel of differential at the other end of the roll shaft of active deflector roll.
Described unidirectional intermittent drive mechanism comprises driving rotating disk, connecting rod, output shaft and ratchet assembly, output shaft is arranged on pedestal, can be with respect to pedestal around its axis rotation, be fixed with the drive bevel gear with described driven wheel of differential engagement on output shaft, one end Eccentric-hinge of connecting rod is connected on and drives on rotating disk, and the other end and ratchet assembly are hinged, and ratchet assembly is arranged on output shaft, under the drive that drives rotating disk, but ratchet assembly driver output axle carries out unidirectional intermittent rotary.
Described Scroll is arranged on pedestal, and it is positioned at discharging one side of active deflector roll and driven deflector roll, and can be with respect to pedestal around its axis rotation, and the roll shaft of described active deflector roll or driven deflector roll is connected with Scroll by the belt pulley transmission mechanism.
Described ratchet assembly is interior mesh ratchet gear assembly, comprises internal tooth ratchet and the pawl disk that coordinates with this internal tooth ratchet, and the internal tooth ratchet sleeve is contained on described output shaft, and pawl disk is fixed on output shaft, and the other end of described connecting rod and internal tooth ratchet are hinged.
Be fixed with fork on the internal tooth ratchet of described ratchet assembly, the other end of described connecting rod and this fork are hinged.
During use, this aluminium strip leftover pieces rolling-up mechanism is arranged on discharging one side of diel on stamping machine by its pedestal, make the sheet metal strip leftover pieces pass and make its front end to be fixed on Scroll between active, driven deflector roll, the driving rotating disk is fixed on an end of stamping machine crank axle.
The operation principle of this rolling-up mechanism is: by unidirectional intermittent drive mechanism, first utilize the crank rocker mode, the rotation that drives rotating disk is converted into the reciprocally swinging of internal tooth ratchet in ratchet assembly, and the unidirectional intermittent rotary of pawl disk, ratchet assembly is passed to Scroll with power one-way intermittent ground by relevant transmission mechanism, and the metal edges corner material after making Scroll to punching press is reeled.
the course of work is: when stamping machine is worked, the stamping machine crank axle rotarily drive the driving turntable rotation, the internal tooth ratchet that drives ratchet assembly by connecting rod is again made reciprocally swinging, in the reciprocally swinging process, the internal tooth ratchet drives pawl disk by the ratchet on pawl disk and makes unidirectional intermittent rotary, pawl disk drives output shaft again and makes unidirectional intermittent rotary, and by active, driven wheel of differential drives the active deflector roll and makes unidirectional intermittent rotary, initiatively deflector roll is by active, driven gear drives driven deflector roll and makes unidirectional intermittent rotary, initiatively deflector roll or driven deflector roll drive the Scroll rotation by the belt pulley transmission mechanism again, thereby the metal edges corner material after punching press is wrapped on Scroll.
This aluminium strip leftover pieces rolling-up mechanism need guarantee the transmission frequency of power at its and the punching press Frequency Synchronization of stamping machine at unidirectional intermittence, i.e. ratchet assembly in this mechanism, initiatively deflector roll, driven deflector roll and the rotational frequency of Scroll and the punching press Frequency Synchronization of stamping machine, when the every punching press of stamping machine once, Scroll rotates once simultaneously, and Scroll rotates the metal edges corner material is wound around, and makes sheet metal strip move forward a punching press station on mould.When work, sheet metal strip continues mobile in the mode of advancing-stopping-readvancing-stopping, discharge through between active deflector roll and driven deflector roll, and be wound around on Scroll, forms the leftover pieces volume.
Aluminium strip leftover pieces rolling-up mechanism of the present invention need not additionally arrange drive source for it owing to having this kind structure, can automatically the metal edges corner material after punching press be collected rolling, has realized the automation that after the punching press, the metal edges corner material is collected; Owing to need not labor cleaning's metal edges corner material, thus alleviated the workman labour intensity, saved disposal costs; And after punching press, the metal edges corner material is collected rolling, can not occupy production site, makes production site hygiene more.
The specific embodiment
The present invention is further elaborated below in conjunction with drawings and Examples:
as Fig. 1, Fig. 2, aluminium strip leftover pieces rolling-up mechanism shown in Figure 3, comprise unidirectional intermittent drive mechanism, pedestal 1, Scroll 4 and active, driven deflector roll 2,3, initiatively, driven deflector roll 2,3 is arranged on pedestal 1 up and down abreast, can be with respect to pedestal around its axis rotation, an end of the roll shaft of active deflector roll 2 and driven deflector roll 3 be fixed with respectively driving gear 5 and with the driven gear 6 of these driving gear 5 engagements, be fixed with driven wheel of differential 8 at the other end of the roll shaft of active deflector roll 2, described unidirectional intermittent drive mechanism comprises driving rotating disk 9, connecting rod 10, output shaft 11 and ratchet assembly 12, output shaft 11 is arranged on pedestal 1, can be with respect to pedestal around its axis rotation, be fixed with the drive bevel gear 7 with described driven wheel of differential 8 engagements on output shaft 11, ratchet assembly 12 is interior mesh ratchet gear assembly, comprise internal tooth ratchet 12a and the pawl disk 12b that coordinates with this internal tooth ratchet, internal tooth ratchet 12a is sleeved on described output shaft 11, pawl disk 12b is fixed on output shaft 11, be fixed with fork 16 on internal tooth ratchet 12a, one end Eccentric-hinge of connecting rod 10 is connected on and drives on rotating disk 9, the other end and this fork 16 are hinged, under the drive that drives rotating disk 9, but ratchet assembly driver output axle 11 carries out unidirectional intermittent rotary, described Scroll 4 is arranged on pedestal 1, it is positioned at discharging one side of active deflector roll 2 and driven deflector roll 3, and can be with respect to pedestal around its axis rotation, the roll shaft of driven deflector roll 3 is connected with Scroll 4 by the belt pulley transmission mechanism, this belt pulley transmission mechanism comprises the driving pulley 13 and the driven pulley 14 that is fixed on Scroll 4 on the roll shaft that is fixed on driven deflector roll 3, is connected with driving-belt 15 at driving pulley 13 and 14 covers of driven pulley.
During use, this aluminium strip leftover pieces rolling-up mechanism is arranged on discharging one side of diel on stamping machine by its pedestal 1, make the sheet metal strip leftover pieces pass and make its front end to be fixed on Scroll 4 between active, driven deflector roll 2,3, driving rotating disk 9 is fixed on an end of stamping machine crank axle.
Aluminium strip leftover pieces rolling-up mechanism is when work, be hinged on the connecting rod 10 that drives on rotating disk 9 and back and forth pull fork 16, make internal tooth ratchet 12a back rotation at a certain angle, by the pawl disk 12b that coordinates to internal tooth ratchet 12a, power one-way intermittent ground is passed to Scroll 4 by relevant transmission mechanism, leftover pieces 17 are by active deflector roll 2 and 3 discharges of driven deflector roll, and are wound and are collected on Scroll 4.
