Problems solved by technology

[0003] The flat bending of round tubes is currently produced through secondary molding (first flattening, second bending) to achieve flat bending of round tubes. Due to multiple positioning of the product, the positioning reference changes, and the accuracy of the product is not high. And the production cost is greatly increased

Embodiment Construction

[0030] Such as Figure 1-3 As shown, a round tube flat bending mold according to an embodiment of the present invention includes: an upper mold 4 fixedly mounted on the bottom of the upper mold frame 1 , and a through hole is processed in the middle of the upper mold 4 . Gas spring A2, gas spring A2 is installed in the inside of patrix 1, and the bottom of gas spring A2 installs locating plate 3, and locating plate 3 passes the middle through hole of patrix 4. Positioning block 5, positioning block 5 is installed on both sides of upper mold 4; Lower mold 7, lower mold 7 is installed on the top of lower mold frame 9, corresponds to upper mold 4, and lower mold frame is fixed on the base 10; Rear positioning seat 6 , the rear positioning seat 6 is located at the right rear side of the lower mold 7, and is fixed with the lower mold frame 9 by bolts. Positioning groove 8, positioning groove 8 is positioned at the both sides of lower mold 7, and position corresponds to positioning...

Abstract

The invention relates to a flat bending mold of a round pipe. A sliding mechanism comprises a triangular frame, wherein a slide way is mounted on the inclined plane of the triangular frame through a bolt; a sliding seat is located in the slide way; a flat mechanism comprises a bracket; a spring frame is fixed at the upper part of the bracket through a bolt; a spring shaft is mounted at the high part of the spring frame; the upper ends of two springs are fixed at the two ends of the spring shaft respectively; and a flat template shaft is arranged at the lower ends of the two springs on one side of the bracket and is connected with the two ends of the flat template shaft. The flat mechanism is combined with the sliding mechanism so that flat bending of the round pipe is realized by one-step molding and a product is positioned in one step; the punching precision of the product is improved; and meanwhile, the production efficiency is improved. The resistance is reduced and the design is reasonable. By utilizing regular motion of the flat template shaft in a sliding groove, the front end of the flat template shaft is located in an inner cavity of the pipe and moves along the bending of the pipe, and the movement precision is improved; and meanwhile, the resetting is rapid and powerful, and the front end of a flat template can be conveniently released from the pipe.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a round tube flat bending die. Background technique [0002] At present, due to the low cost of stamping products, as the application of punching machines is becoming more and more popular at home and abroad, and the stamping accuracy is improved, many products are produced by stamping, and many workpieces with complex shapes are also produced by stamping. Production In order to improve the precision of the product and reduce the production cost of the product, the manufacturer has fully improved the mold. [0003] The flat bending of round tubes is currently produced through secondary molding (first flattening, second bending) to achieve flat bending of round tubes. Due to multiple positioning of the product, the positioning reference changes, and the accuracy of the product is not high. And the production cost is greatly improved. Contents of the invention [0004] In...
