Description

Metal sheet stock automatic positioning pay-off stamping device

Technical Field

The utility model belongs to the technical field of the hardware processing technique and specifically relates to a metal sheet material automatic positioning pay-off stamping device.

Background

In the process of making small metal parts, a stamping press is typically used to punch a sheet of material suitable for processing from a coil. These sheets are generally regular circles, ovals and rectangles. Among the prior art, in order to make the coiled material comparatively laminate the lower mould in punching press station department, generally be provided with a pair of spacing roller respectively in the front and back of lower mould, can prevent through spacing roller that the coiled material of punching press station from taking place the displacement by a wide margin of about arbitrary direction when receiving the drift impact. But the defects of the prior art are as follows: after the coiled material is punched, the sheet material and the coiled material are not fixedly connected, part of the sheet material is driven to slightly protrude out of the coiled material when the punch is reset, and when the section of the coiled material carrying the sheet material passes through the pair of limiting rollers at the back, the sheet material can be clamped between the limiting rollers.

In addition, although the sheet material is already in a fixed connection with the coil by punching, the sheet material does not necessarily automatically separate from the coil due to friction because of contact between the sheet material and the coil.

Disclosure of Invention

the utility model provides a metal sheet stamping device who is difficult to block, takes off the material easily to the not enough of prior art.

The technical scheme of the utility model is that:

The utility model provides a metal sheet material automatic positioning pay-off stamping device, it includes base, punching machine, lower mould, material blowing, receipts material book, preceding spacing roller set and back spacing roller set, its characterized in that: the base is welded with a first support, a second support, a third support, a fourth support and a fifth support from front to back in sequence on two sides, the two first supports are used for installing a material placing roll together, the two second supports are used for installing a front limiting roller set together, the two third supports are used for installing a punching machine together, the two fourth supports are used for installing a rear limiting roller set together, the two fifth supports are used for installing a material collecting roll together, a lower die is installed on the base and positioned below the punching machine, a pressure sensitive adhesive block is adhered to the position, between the punching machine and the rear limiting roller set, of the top surface of the base, a plastic basket is placed on the pressure sensitive adhesive block and used for collecting sheet materials separated from the coiled materials, a motor is installed at the tail end of the base, the coiled core of the material collecting roll extends out of the fifth support, a rotating shaft of the motor is connected with the coiled core through a transmission chain to realize the rotation of the material collecting roll, and, install a compression roller on the bracket, the bottom surface of compression roller flushes with the bottom surface of the last roller in the preceding spacing roller set, the bottom surface of compression roller is less than the top surface of the lower roll in the back spacing roller set, and its effect is: the punched sheet material is brought to the press roller by the sheet material, and because of the height difference between the press roller and the rear limiting roller group, the sheet material and the sheet material are influenced by the arc-shaped surface of the press roller, and the sheet material is also deformed along the surface of the press roller by the pulling force of the receiving roller, but the sheet material and the sheet material have no fixed connection relationship and have higher hardness, so that the sheet material is extruded out of the bent sheet material by the arc-shaped surface of the press roller equivalently, and then the bent sheet material falls into a plastic basket.

specifically, the front limiting roller set and the rear limiting roller set are different only in installation position.

Specifically, the front limiting roller set comprises two rollers, one roller is an upper roller, the other roller is a lower roller, and the two rollers are arranged in the mounting frame in parallel. The upper and lower rollers limit the web fluttering up and down.

Specifically, the roll surfaces of the front limiting roll group and the rear limiting roll group are coated with pressure-sensitive adhesive layers, and the pressure-sensitive adhesive is pressed to generate large friction force after the coiled material contacts the pressure-sensitive adhesive, so that the left and right offset amplitude of the coiled material under extreme conditions is reduced.

Specifically, the compression roller is positioned above the plastic basket, so that the sheet materials separated from the coiled materials can fall into the plastic basket conveniently.

Specifically, the motor is frequency conversion gear motor, can the manual control rotational speed to make the rolling comparatively even, also can realize full-automatic rolling control with equipment such as extension tension controller, encoder, of course, these are not the utility model discloses a protection scope.

Specifically, adopt detachable the connection between material roll and the first support, be convenient for change the material.

The utility model has the advantages that: even if the sheet material protrudes out of the coiled material after being stamped, the sheet material can be extruded out of the coiled material by the compression roller before entering the rear limiting roller set, so that the two purposes are achieved, the rear limiting roller set cannot be clamped, and the sheet material can be automatically blanked.
