Automatic mold change device of multi-station cold heading machine

Abstract

The invention discloses an automatic mold change device of a multi-station cold heading machine. The device comprises a mounting frame; the mounting frame is provided with a first pneumatic finger forextracting molds and a second pneumatic finger for clamping the molds; a connecting plate is arranged between the first pneumatic finger and the second pneumatic finger; and the mounting frame is provided with a first driving mechanism for driving the first pneumatic finger and the second pneumatic finger to move in the width direction of the mounting frame, a second driving mechanism moving in the length direction of the mounting frame, and a third driving mechanism moving the height direction of the mounting frame. The device has the following beneficial effects: the first pneumatic fingerand the second pneumatic finger move in three dimensions of length, width and height of the mounting frame, and are aligned to target molds; and the molds are extracted out from a mold cavity throughthe first pneumatic finger and clamped through the second pneumatic finger to realize automatic mold change of the cold heading machine.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to an automatic mold changing device for a multi-station cold pier machine. Background technique [0002] The cold pier machine is a fast stamping processing machine. Its processing adopts the processing technology of less cutting and no cutting, and has the characteristics of high efficiency, green and energy saving. [0003] Most of the domestic cold heading machine mold change work is manually replaced by workers, and the manual replacement of cold heading machine molds has the following problems: the current cold heading machine models are generally compact in structure, and the space for workers to change molds is small, making workers It is inconvenient to operate; the molds of cold heading machines are mostly cylinders with large mass, and the appearance is smooth, and there is no suitable force point, so it is difficult to hold with bare hands and easy to slip, which ...

Problems solved by technology

[0003] Most of the domestic cold heading machine mold change work is manually replaced by workers, and the manual replacement of cold heading machine molds has the following problems: the current cold heading machine models are generally compact in structure, and the space for workers to change molds is small, making workers It is inconvenient to operate; the molds of cold heading machines are mostly cylinders with large mass, and the appearance is smooth, and there is no suitable point of force, so it is difficult to hold with bare hands and easy to slip, which poses a large safety hazard; The mold change method of the cold heading machine is mostly a single single-station mold change. After a set of molds are replaced, the equipment will have a long downtime, which seriously affects the production efficiency.

Foreign cold heading machines have a high degree of automation, and use multi-joint coordinate robots to complete the mold change, which is fast and accurate, but the cost of the whole set of equipment is relatively high, and it needs to occupy a large installation space
