Abstract

The utility model relates to an improved bending mold of a metal plate, which is characterized in that horizontal forming through slots are symmetrically arranged on the upper sections of a left and a right inclined planes of a v-shaped slot of a lower mold along the length direction of the lower mold, the forming through slots have cross sections in the shape approximating to a circle or a rectangle and forming embedded strips are correspondingly embedded in every forming through slot. The cross sections of the forming through slots are made into a circular or a rectangular shape, the forming embedded strips and the lower mold are embedded as a whole, and partial forming embedded strips exposed out of the gaps of the forming through slot are higher than the left and the right inclined planes of the v-shaped slot. The bending surfaces of metal materials can move along the exposed surfaces of the forming embedded strips in the process of bending the metal materials, the forming embedded strips can be gradually deformed via compression, the bending surfaces of the metal materials can not directly contact with the metal part of the lower mold, and thus the aim that the bending surfaces of the metal materials have no pressing mark is obtained, the quality and the grade of products bent from the metal materials are raised and the qualified rate of the products is increased.

Description

No impression mould

Technical field:

The utility model belongs to the shaping jig of metallic plate extruding, especially a kind of mould of metallic plate extrusion modling.

Background technology:

Metal blank, especially the sheet metal of thickness below 2mm, on dedicated extruded bender during Bending Processing, metallic plate pushes in the process that enters existing mould bending and directly contacts with mould metal position, the normal bending impression that produces in its bending surface, easily make the bending surface tear of metallic plate and influence the quality and the outward appearance of product, reduced the class and the qualification rate of product.

Summary of the invention:

The purpose of this utility model provides a kind of improved metallic plate Bending Mould, and metallic plate extruding is entered in the mould bending process, and the no impression in the bending of metallic plate surface improves quality, class and the qualification rate of metallic plate bending product effectively.

The purpose of this utility model is achieved like this: a kind of by patrix, counterdie, the no impression mould that die shoe is formed, it is characterized in that being positioned at the left side of the V-shaped groove mouth of counterdie, the epimere position of right tilted surface, press the length direction of counterdie, on counterdie, respectively offer the moulding groove of level symmetrically, the cross section of this moulding groove is sub-circular or approximate rectangle, equal setting-in moulding filler rod correspondingly in each moulding groove, the cross section of this moulding filler rod correspondingly is processed into circle or rectangle, adopt polyurethane, excellent power blob of viscose is processed into, polyurethane, excellent power blob of viscose is all flexible, toughness and wearability, moulding filler rod and counterdie setting-in are integral, and locally-shaped filler rod exposes to the gap of moulding groove, exceeds the left side of V-shaped groove mouth, right tilted surface; When the metal blank bending, to go up earlier, counterdie, the die shoe clamping is fixed on the special-purpose bender, adjust, the center of counterdie, select for use suitable metal blank to place on the last plane of counterdie V-shaped groove according to the size of counterdie V-type notch, adjust the pressure of bender then, stroke, just can start bender work, patrix is descending, make metal blank in the bending process, the bending surface of metal blank is along the moulding filler rod distortion of moving and gradually reduce of the exposed surface of moulding filler rod, the bending surface of metal blank does not directly contact with the metal position of counterdie, thereby reach the purpose of the no impression in bending surface of metal blank, improve the quality of metal blank bending product effectively, class and qualification rate.

The no impression mould structure that the utility model is carried is reasonable, safe and reliable, improves quality, class and the qualification rate of metal blank bending product effectively.

The no impression mould of the utility model being carried below in conjunction with drawings and Examples is further described.

Description of drawings:

Fig. 1 is one of schematic diagram of the no impression mould carried of the utility model.

Fig. 2 be the no impression mould carried of the utility model schematic diagram two.

The specific embodiment:

From Fig. 1, among Fig. 2 as can be seen: a kind of by patrix 1, counterdie 5, the no impression mould that die shoe 6 is formed, it is characterized in that being positioned at the left side of the V-shaped groove mouth of counterdie 5, the epimere position of right tilted surface, press the length direction of counterdie 5, on counterdie 5, respectively offer the moulding groove 3 of level symmetrically, the cross section of this moulding groove 3 is sub-circular or approximate rectangle, equal setting-in moulding filler rod 4 correspondingly in each moulding groove 3, the cross section of this moulding filler rod 4 is processed into circle or rectangle accordingly, when the cross section of moulding groove 3 is sub-circular, wherein corresponding setting-in cross section is circular moulding filler rod 4, when the cross section of moulding groove 3 during for approximate rectangle, wherein corresponding setting-in cross section is rectangular moulding filler rod 4, moulding filler rod 4 adopts polyurethane, excellent power blob of viscose is processed into, polyurethane, excellent power blob of viscose is all flexible, toughness and wearability, moulding filler rod 4 is integral with counterdie 5 setting-ins, and local moulding filler rod 4 exposes to the gap of moulding groove 3 and exceeds the left side of V-shaped groove mouth, right tilted surface; When metal blank 2 bendings, to go up earlier, counterdie 1,5, die shoe 6 clampings are fixed on the special-purpose bender, adjust, counterdie 1,5 center, select for use suitable metal blank 2 to place on the last plane of V-shaped groove of counterdie 5 according to the size of the V-type notch of counterdie 5, adjust the pressure of bender then, stroke, just can start bender work, patrix 1 is descending, make metal blank 2 in the bending process, the bending surface of metal blank 2 is along moulding filler rod 4 distortion of moving and gradually reduce of the exposed surface of moulding filler rod 4, the bending surface of metal blank 2 does not directly contact with the metal position of counterdie 5, thereby reach the purpose of the no impression in bending surface of metal blank, improve the quality of metal blank bending product effectively, class and qualification rate.
