Problems solved by technology

However, the material of the thin plate itself is easy to cut and process. During processing, the sheet metal part is often cut into a size that meets the processing size, and then extruded to obtain the required workpiece. This method separates cutting and extrusion. Invisibly increase the processing time and reduce the processing efficiency

Embodiment Construction

[0011] Such as figure 1 As shown, the continuous feeding extrusion molding mechanism of the present invention includes a base 1 on which a vertical concave mold 2 is provided, and the upper end surface of the concave mold 2 is a curved surface. The base 1 is also provided with two roller racks 3, the two roller racks 3 are symmetrically arranged on both sides of the die 2. The top of the roller rack 3 is hinged with a transmission roller 4; the base 1 also includes a die 5, The mold 5 is located directly above the concave mold 2, and a convex surface matching the arc surface of the concave mold 2 is provided under the pressing mold 5. The roller frame 3 is fixed on the base 1 by countersunk screws 6. A jack 7 penetrating the base 1 is fixed at the lower end of the concave mold 2. An installation key block 8 is provided on the roller frame 3. The installation key block 8 is provided, and a suitable cutting punch can be installed through the installation key block 8 to adapt t...

Abstract

The invention relates to a continuous feeding extrusion forming mechanism. A plate is fed in the mechanism till the whole end of the plate enters a work position, a press mold is operated to extrude the plate downwards, and work-pieces of the required shapes are machined under the action of the press mold and a female mold. By means of the mechanism, input plates can be guided and supported through rollers, so that the whole mechanism can perform intermittent punching on the continuous plates; by the fitting of a corresponding blanking die, punching can be completed immediately after extrusion forming through one step, and the extrusion formed work-pieces can be blanked; forming and blanking are combined, so that the problem of consuming of time and labor of traditional step-by-step machining is solved, blanking can be completed after extrusion forming, and the machining efficiency is improved.

Description

Technical field [0001] The invention relates to an extrusion molding mechanism, in particular to a continuous feeding extrusion molding mechanism. Background technique [0002] Blanking die is an indispensable process equipment in stamping production, and a good die structure is a reliable guarantee for the realization of the process plan. The quality and accuracy of stamping parts mainly depend on the quality and accuracy of the punching die. Whether the structure of the punching die is reasonable and advanced will directly affect the production efficiency, the service life of the punching die itself, and the safety and convenience of operation. Due to the different shape, size, precision, production batch and production conditions of the blanking parts, the structure of the blanking die is also different. The punching die is mainly used for blanking and punching of various plates. The working part of the die is the cutting edge of the convex and concave molds. The cutting edg...
