Description
Technical field
The utility model relates to a kind of punching machine mold, relates in particular to a kind of punching machine mold that is used to make open type pipe end protective sleeve.
Background technology
The protection problem of steel pipe in transport process is the mandatory requirement of standard and technical specification; As pipe-line; Convenience when steel pipe is installed butt joint in the building site and ensuring the quality of products all requires steel pipe dispatching from the factory before, process bevel for welding, but unloads the steel pipe end face of can damaging unavoidably in the process transporting and lift; Thereby the influence construction is so must adopt protective sleeve to protect when dispatching from the factory.Because the dimensions of steel pipe is a lot, and the steel pipe of every kind of different-diameter different wall requires adapted different protection cover, and so, the dimensions of protective sleeve is also a lot, and this must bring many troubles to production.Occur a kind of protective sleeve at present, it is the open type tube-in-tube structure that adopts sidewall opening, the opening two ends is linked together again, and the protective sleeve of this structure is applicable to the steel pipe of plurality of specifications.The mode together that opening two ends on the open type sleeve lateral wall are connected has a lot, as at the opening two ends recess being set respectively, between two recesses, clamping wedge again and carries out fastening.But, the punch press that designs to the protective sleeve of this structure appears in the market as yet, though the recess at the structure split shed two ends of this protective sleeve adopts common in the market punch press also can realize, inefficiency, wastes time and energy.
The utility model content
The purpose of the utility model is exactly for fear of the prior art deficiency a kind of punching machine mold that is used to make open type pipe end protective sleeve to be provided.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of punching machine mold; Comprise die holder, die, jacking block, punch, holddown spring and positioner; Said bottom of female die is fixedly connected on the said die holder, and the center of said die has through hole, and said holddown spring and said jacking block all are arranged in the through hole of said die; And the top of said holddown spring is positioned at the below of said jacking block; The bottom of said holddown spring is positioned at said die holder top, is provided with convexity in the top center position of said jacking block, and said punch is arranged on the top of said die; And said punch position is corresponding with said jacking block raised position, and said die is provided with the positioner that is used for fixing workpiece.
Further, the bottom centre of said jacking block has groove, and the top of said holddown spring is positioned at said groove.
The beneficial effect of the utility model is; The utility model punching machine mold can be used for making open type pipe end protective sleeve; Jacking block in punch and die and the die cooperatively interacts, directly the recess at the sidewall opening two ends of punch forming open type pipe end protective sleeve.The utility model punching machine mold is simple in structure, reasonable in design, has improved the operating efficiency when manufacturing open type pipe end protective sleeve, and is time saving and energy saving.
Description of drawings
Fig. 1 is the structural representation of the utility model punching machine mold;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As depicted in figs. 1 and 2, a kind of punching machine mold comprises die holder 1, die 2, jacking block 3, punch 4, holddown spring 5 and positioner 6; The bottom of die 2 is fixedly connected on the die holder 1, and the center of die 2 has through hole 20, and holddown spring 5 all is arranged in the through hole 20 of die 2 with jacking block 3; The bottom centre of jacking block 3 has groove 30; The top of holddown spring 5 is positioned at groove 30,, the bottom of holddown spring 5 is positioned at die holder 1 top; Be provided with protruding 30 in the center at jacking block 3 tops; Punch 4 is arranged on the top of die 2, and punch 4 positions are corresponding with convexity 30 positions on the jacking block 3, and die 2 is provided with the positioner 6 that is used for fixing workpiece.
The utility model punching machine mold in use; With two sheet metal workpiece A, B is separately fixed at the convexity 30 at jacking block 3 tops through positioner 6 both sides after crimping is handled; And make the both sides of two sheet metal workpiece A, B and convexity 30 fit tightly; Drive punch 4 through hydraulic power unit and move downward, punch 4, die 2, jacking block 3, holddown spring 5 cooperatively interact, at two sheet metal workpiece A, the last recess that stamps out open type pipe end protective sleeve sidewall opening place of B.
In order to raise the efficiency; Stamping Die Design becomes to be washed into two open type pipe end protective sleeves twice; Promptly be close together the right-hand member of the left end of sheet metal workpiece A and sheet metal workpiece B for the first time and dash, be close together the left end of the right-hand member of sheet metal workpiece A and sheet metal workpiece B for the second time and dash.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
