Embodiment Construction

[0021] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0022] Such as Figure 1-3 As shown, a multi-station lower ejecting device for cold extrusion includes a cam assembly, a transmission assembly, an ejection assembly and a pneumatic assembly. The cam assembly drives the ejection assembly to rotate simultaneously through the transmission assembly and the pneumatic assembly. The cam assembly includes a transmission cam 1, a cam rocker 2 and a cam roller 3, one end of the cam rocker 2 is fixed by a fixed shaft 16, the cam roller 3 is fixed in the middle of the cam rocker 2, and the transmission cam 1 is set Under the cam roller 3 and against the cam roller 3, the transmission cam 1 is installed on the main transm...

Abstract

The invention relates to a multi-station lower ejection device for cold extruding. The device comprises a cam assembly, a transmission assembly, an ejection assembly and a pneumatic assembly, wherein the cam assembly drives the ejection assembly to rotate by the transmission assembly and the pneumatic assembly, so that a workpiece can be ejected out of a mould. After the multi-station lower ejection device for cold extruding is used, the problems in the prior art that the ejection stroke is not enough, the ejection device is rigidly impacted, the ejection stroke is not matched with the movement of a sliding block of a cold extruding machine very well, and a cold extrusion part is difficult to guide out from a mold cavity can be solved, and the operation stability and the matching property of the system can be guaranteed.

Description

technical field [0001] The invention relates to the field of cold extrusion, in particular to a multi-station bottom jacking device for cold extrusion. Background technique [0002] Cold extrusion is a metal plastic forming processing method, which is to put the metal blank in the cold extrusion die cavity, and at room temperature, apply pressure to the blank through the fixed punch on the cold extrusion machine, so that the metal blank produces plastic deformation And the processing method of the parts. Therefore, the metal blank is forced to form in the mold cavity by means of strong pressure and a certain speed, and finally obtains the desired shape and size. In the process of forming the metal blank in the mold cavity, due to the large unit flow pressure, the mold will produce a large elastic deformation at this time. After the extrusion is completed, the extruded workpiece will often be stuck in the mold cavity. In the process, if the extruded workpiece is to be taken...
