Abstract

The utility model discloses a punching shear die for a square steel pipe, which comprises an upper die and a lower die, wherein an upper die cutting edge is formed on the lower end surface of the upper die, and a plurality of bolt holes are formed on a main body of the upper die; a hanging block is arranged on the lower die; a lower die cutting edge corresponding to the upper die cutting edge is formed in the hanging block; and fastening holes are formed on the main body of the lower die. The punching shear die can punch a notch of the square steel pipe by combining a punch and the upper die as well as the lower die, is simple and feasible, saves extensive processing workload, lowers the manufacturing cost, and guarantees the product quality.

Description

A kind of square steel pipe punching and shearing die

Technical field

The utility model belongs to plant equipment manufacturing technology field, relates to a kind of square steel pipe punching and shearing die.

Background technology

During welding structural elements such as tolerance for wire rod cooling bed roller are made, often run into and if adopt existing processing method to implement processing, then need take slotting machine (not allowing the angle, garden) to the situation of square steel pipe machining gap (tooth plate patchhole), waste time and energy; If adopt oxy-acetylene to cut and do not reach the drawing requirement, such as, its cutting surface quality is relatively poor, the gas cutting linearity is poor, the gas cutting slag is cleared up difficulty etc., has seriously influenced the assembly quality of product.

Summary of the invention

The purpose of this utility model provides a kind of square steel pipe punching and shearing die, and it is promptly time-consuming to have solved the processing of existing square steel pipe breach, the problem that the machining hole dimensional accuracy is low.

The technical scheme that the utility model adopted is, a kind of square steel pipe punching and shearing die comprises upper die and lower die, and the lower surface of described patrix is provided with the patrix cutting edge, and the main body of patrix is provided with some bolts hole; Described counterdie is provided with a suspended block, has in this suspended block and the corresponding counterdie cutting edge of patrix cutting edge, and the main body of counterdie is provided with joint hole.

Square steel pipe punching and shearing die of the present utility model, its feature also be,

The upper surface of described counterdie and suspended block is positioned at same horizontal plane.

Square steel pipe punching and shearing die of the present utility model, simple in structure, can easily be used with punch press, guaranteed the machining accuracy of square steel pipe, reduced production cost.

Among the figure, 1. patrix, 2. patrix cutting edge, 3. bolt hole, 4. counterdie, 5. counterdie cutting edge, 6. joint hole, 7. square steel pipe part, the 8. breach that becomes of punching out, 9. working face on the punch press, 10. working face under the punch press, 11. bolts, 12. closing bolt.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Square steel pipe punching and shearing die of the present utility model, its structure are to comprise patrix 1 and counterdie 4.As Fig. 1, the lower surface of patrix 1 is provided with patrix cutting edge 2, is vertically installed with some bolts hole 3 on the main body of patrix 1.As Fig. 2, Fig. 3, counterdie 4 is provided with a suspended block, and the upper surface of this suspended block and counterdie 4 is positioned at same horizontal plane, has in this suspended block and the corresponding counterdie cutting edge 5 of patrix cutting edge 2 sizes, guarantee patrix cutting edge 2 and the 5 realization punchings of counterdie cutting edge, be vertically installed with joint hole 6 on the main body of counterdie 4.Patrix 1 and counterdie 4 all adopt the T8 steel, machine-shaping after quenching.

As Fig. 4, be the part schematic diagram of square steel pipe palpus machining gap, at the sidewall of square steel pipe part 7, need the breach 8 of processing punching out.

As Fig. 5, mould of the present utility model in use, at first patrix 1 is fastenedly connected by working face 9 on the punch press of bolt 11 and 60 tons, adjust the counterdie horizontal level, make upper and lower mould cutting edge cooperate smoothly, counterdie 4 is fastenedly connected by the following working face 10 that handle closes bolt 12 fastening means and punch press.Then, after the square steel pipe of required machining gap being inserted counterdie cutting edge 5 one ends of counterdie 4 tape shapes, seam location, bottom, and the adjustment square steel pipe equates the startup punch press with the gap of counterdie 4 both sides, after treating patrix 1 and counterdie 4 contacting and thrusts, square steel pipe is taken out, insert required another side again, readjust square steel pipe and equate with gap between the counterdie both sides towards breach, start punch press, square steel pipe another side breach is finished with regard to punching out.

The mode that punching and shearing die of the present utility model adopts punch press to combine with mould, during punching out square steel pipe breach, the upper and lower mould cutting edge size of patrix and counterdie is provided with as required flexibly, simple, save a large amount of labor contents, reduce production costs, guaranteed product quality.
