Embodiment 1

[0014] exist figure 1 Among them, the cylinder beating device includes nine beating rods 6, which all penetrate the body of the slider 1 from top to bottom.

[0015] An air reservoir 2 is fixed on the side end surface of the slider 1, and is arranged transversely according to the length of the cylinder.

[0016] Nine beating cylinders 4 are fixed on the same horizontal line on the slide block side end face below the air reservoir 2 .

[0017] exist figure 2 Among them, the feeding cylinder 4 is composed of a loam cake 401, a cylinder body 402, and a lower cover 403 to form a cylinder, which is fixed on the side end surface of the slide block 1 vertically by stud screws corresponding to the feeding rod and the cylinder body.

[0018] A piston 404 is arranged in the air chamber of the cylinder, and the piston rod 5 connected with the piston 404 extends out of the cylinder. Such as figure 2 As shown, the upper cover 401 and the cylinder body 402 are sealed by an O-ring 405 ...

Embodiment 2

[0023] The cylinder feeding device also includes a feeding rod that runs through the slider body from top to bottom, an air storage tank fixed on the side end surface of the slider, a feeding cylinder fixed on the side end surface of the slider below the air storage tank, and a connected air storage tank. The connecting pipeline with the cylinder air chamber and the piston rod extending out of the cylinder and connected with the piston in the cylinder air chamber. Its component structure, installation location and connection relationship are the same as those in Embodiment 1, so I won't repeat them here.

[0024] One difference from the embodiment is that because the product molds of various manufacturers are different, the punching positions are also different, so the position of the punching rod needs to be set according to different molds. Therefore, the piston rod of the material beating cylinder cannot be in one-to-one correspondence with the material beating rod.

Abstract

The invention relates to a pressure machine cylinder knockout device, which comprises a knockout rod penetrating through a slider body from top to bottom, and is characterized in that an air reservoir is fixed on the side end face of a slider; a plurality of knockout cylinders are fixed in the same horizontal line on the side end face of the slider below the air reservoir; the air reservoir is respectively communicated with an air chamber of each knockout cylinder through a connecting line; a piston is arranged in the air chamber of each knockout cylinder; piston rods connected with the pistons extend out of the cylinders to drive the knockout rod to descend to carry out knockout; the strokes of the piston rods in the knockout cylinders make the knockout rod extend out of the outer side of an upper mould below the slider to separate a molding stamping part which is glued together with the upper mould from the upper mould. The invention has even force application, soft knockout force, stable knockout, reliable working, low noise and high product yield.

Description

technical field [0001] The invention relates to a discharge device of a press, in particular to a press cylinder discharge device for separating a molded workpiece on a mold from the mold. Background technique [0002] We know that after the press presses the workpiece, the slider drives the upper mold upward. Due to the high pressing force of the stamping parts during the pressing process, the formed stamping parts usually fit on the lower side of the upper mold under the slider. , cannot fall off freely from the upper mold, so it is necessary to set up a feeding mechanism to knock off the stamping parts from the upper mold, so as to prepare for continuous work or next stamping. The beating device usually adopted in the existing press is a rigid beating device. For example, CN201244927Y Chinese Invention Patent Specification published on May 27, 2009 discloses a "rigid feeding device for a press", which includes a feeding screw screwed at one end and capped, a connecting p...
