Hollow square tube character pressing device

Abstract

The invention relates to a hollow square tube character pressing device. The hollow square tube character pressing device is characterized by comprises a lower mold plate, a wedge block support, an upper mold assembly and a demolding tapered wedge which are used in cooperation; the lower mold plate is provided with a side positioning stopping part and an end positioning stopping part; the wedge block support comprises an upper wedge block and a lower wedge block, self-locking slopes which are matched with each other are machined at the lower portion of the upper wedge block and the upper portion of the lower wedge block, and the upper wedge block is provided with a square hole where the demolding tapered wedge is inserted; and the upper mold assembly comprises a fixing plate, an initial block and a pressing plate, the fixing plate is arranged at the bottom of the pressing plate, and the initial block is installed in a character block square hole in the middle of the bottom face of the fixing plate. The hollow square tube character pressing device is fastened into a hollow square tube in a wedged manner, looseness caused by slippage of the upper wedge block during pressing printing can be avoided, the beneficial effects of being large in support body strength, simple in operation and convenient are achieved, deep type permanent marker pressing can be achieved, and pressing printing deformation can be avoided.

Description

technical field [0001] The invention relates to pipe embossing, in particular to a hollow square pipe embossing and word embossing device. Background technique [0002] With the market's increasing requirements for the traceability of the product manufacturing process, it is necessary to leave traceable marks such as the manufacturer, production date, and serial number on the product or component. permanent marker. Now the permanent mark manufacturing generally adopts the engraving process of the engraving machine, and its depth is usually less than 0.3mm; when the depth requirement is greater than 0.3mm, the molding process is required. Some railway wagons require permanent marks with a depth of 0.8mm to be pressed on the hollow pipe, such as a 100X140X6 rectangular hollow square pipe. Due to the high molding pressure, the rectangular square pipe will bulge and collapse when stamped with a traditional stamping die. and other deformations, resulting in unclear embossing an...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the defects of insufficient strength of the hollow square tube itself and easy deformation of embossing, the present invention provides a hollow square tube embossing device, which uses the principle of self-locking wedges to wedge tightly in the hollow square tube, and can avoid wedges during embossing The block slips and loosens, and has the characteristics of strong support body, simple operation and convenience, and can realize the pressing of deep permanent marks without causing deformation of the embossing
