Problems solved by technology

However, the cost of the above-mentioned processing method is high, and the requirements for equipment are also high, and it has the advantage of high processing accuracy.
However, for parts that do not require high edge dimensional accuracy, the above-mentioned processing method will result in waste of cost. Therefore, a simple edge trimming method needs to be considered

Embodiment Construction

[0011] Such as figure 1 As shown, the inverted mold chuck of the present invention includes a base 1, on which a vertical sleeve 2 is arranged, the open end of the sleeve 2 passes through the base 1, and a hole is provided at the open end to prevent the sleeve 2 from coming out of the base 1. Card platform, a push rod is installed in the sleeve 2, a top 3 is provided at the end of the push rod, and a spring 4 is arranged between the top 3 and the sleeve 2 on the push rod; two supports are fixed on the base 1 5. The support 5 is symmetrically arranged on both sides of the sleeve 2. The inner side of the support 5 is hinged with a chuck 6. The upper end of the chuck 6 is in contact with the top 3. The lower end of the chuck 6 is provided with a workpiece clamping groove, and the workpiece clamping groove There is a neck for clamping the workpiece. The lower end surface of the chuck 6 protrudes from the lower end surface of the support 5 . This setting can facilitate the blanki...

Abstract

The invention discloses an inverted die chuck. A vertical sleeve is arranged on a base, a spring in the sleeve can function in returning and pressing an ejector rod, the end of the ejector rod contacts with the chuck, the chuck can be fixedly extruded, a workpiece in the chuck is clamped, and a fixing function is achieved. Furthermore, a support can simultaneously serve as a punching female die and is matched with a corresponding punching male die, so that clamping and edge punching can be finished together. By the clamping and punching mode, the edge of the workpiece can be conveniently treated, the inverted die chuck is simple and rapid in machining, excessive labor cannot be consumed, and cost is saved.

Description

technical field [0001] The invention relates to a mechanical processing device, in particular to an inverted mold chuck. Background technique [0002] The 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 precision of stamping parts mainly depend on the quality and precision 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 shapes, sizes, precision, production batches and production conditions of blanking parts, the structure types of blanking dies are also different. The blanking die is mainly used for blanking and blanking of various plates. The working part of the die is the cutting edge of the convex and concave dies. When the cutting edge is wo...
