Abstract

The invention discloses a chain type die clamping device. The device comprises a cylinder, wherein the cylinder comprises a cylinder body, and a piston rod arranged in the cylinder body. The device further comprises a chain guide seat, a chain, a chain wheel and a die clamper; the bottom part of the cylinder body is fixed to the chain guide seat; an arc-shaped through groove for guiding the chain moving track is formed in the chain guide seat; one end of the chain extends out of the arc-shaped through groove and is fixedly connected to the die clamper, and the other end of the chain bypasses the piston rod to be fixedly connected to the cylinder body; the chain wheel is fixed to a head part of the piston rod and is engaged with the chain. According to the chain type die clamping device, the chain guide seat is fixed to a table tray edge of a punching machine, and the chain vertically moves to drive the die clamper to horizontally move so as to achieve the effect of pushing and pulling the die clamper to the side edge of a die; meanwhile, a chain driving part is mounted at the outer part of the side edge of the punching machine, so that the space of the table top of the punching machine is not occupied for the chain driving part, and as a result, the influence on the use of a big die is avoided.

Description

technical field

[0001] The invention relates to a die clamp for a punch press, in particular to a chain type clamp. Background technique

[0002] At present, in the quick mold change industry of punch presses, self-propelled clamps are fixed on the punch presses to clamp the molds on the punch presses. The self-propelled clamps currently used are in the form of cylinder push-pull, but such a method The cylinder needs to be installed on the table top of the punch press, which takes up a lot of space and makes it impossible to use larger molds. Contents of the invention

[0003] The technical problem solved by the invention is to provide a chain clamp that does not occupy the space on the punch table and does not affect the use of large molds.

[0004] The technical solution adopted by the present invention to solve the technical problem is: the chain mold clamp includes a cylinder, the cylinder includes a cylinder body and a piston rod arranged in the cylinder body, and al...
