Abstract
The utility model discloses a forming die for processing a saddle curve connecting pipe. The die comprises a punch and a concave die, wherein the punch is connected with a punch base plate by a punch shank, the concave die consists of an upper die and a lower die, the front end of the punch is an extrusion molding surface forming a cylindrical convex surface, and the concave die comprises a forming cavity consisting of a forming inner cavity and an auxiliary forming inner cavity; a forming groove fitting with the extrusion molding surface of the punch is arranged on the inner wall of one end of the forming inner cavity, the end is communicated with the auxiliary forming inner cavity, the crossed edges form saddle-shaped curves, and the auxiliary forming inner cavity is a compression molding surface fitting with the extrusion molding surface of the punch. The utility model has the characteristics of simple structure, low cost, short production work hours and convenient die maintenance. The forming die is suitable for muffler industry.
Description
Technical field
The utility model belongs to mould.
Background technology
Existing tube-end forming to tubular part in the gas extraction system is to adopt mold for extruding and forming, but for the higher tubular part of complexity, especially the end is the tubular part of different form, as saddle curve tube connector etc., its mold for extruding and forming not only complex structure, cost is higher, and it is longer to produce man-hour.
Summary of the invention
The purpose of this utility model is to provide a kind of shaping dies that is used to process saddle curve tube connector at above-mentioned deficiency, to realize that mould structure is simple, cost is low and to produce short purpose in man-hour.
In order to realize above purpose, a kind of shaping dies that is used to process saddle curve tube connector that the utility model provides, comprise the punch that is connected with the punch seat board by die shank, the die of forming by upper die and lower die, the front end of described punch is the extrusion molding face of cylindrical convex surface, described die comprises the forming cavity that is made of shaping inner chamber and assist formation inner chamber, wherein, the inwall of shaping inner chamber one end is provided with the grooving that matches with the extrusion molding face of punch, this end is communicated with and intersects the edge with the assist formation inner chamber and is saddle-shaped curve, the pressurized forming face of assist formation inner chamber for matching with the extrusion molding face of punch.The extrusion molding face of punch pushes mutually with the inwall of the forming cavity of die, and the tube connector pressurized is shaped.
The other end of described shaping inner chamber is provided with locating ring.
The cylindrical concave surface of described pressurized forming face.
The front end of described punch is provided with the guiding correcting block that is used to lead and proofreaies and correct the part flange height that is formed, and this guiding correcting block is used for the guiding of punch early stage being shaped, and is used to proofread and correct the height of part flange of being formed in the later stage that is shaped, and guarantees that it is in error range.
The utility model not only has simple in structure, and cost is low, produces short characteristics in man-hour, and has mould characteristics easy to maintenance.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 takes the plan structure schematic diagram of patrix off for Fig. 1.
Structural representation when Fig. 3 works for the utility model.
Among the figure: 1-die shank, 2-punch seat board, 3-punch, 4-die (41-patrix, 42-counterdie, 43-shaping inner chamber, 44-assist formation inner chamber, 45-grooving), 5-locating ring, 6-guiding correcting block, 7-saddle curve tube connector.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment: a kind of shaping dies that is used to process saddle curve tube connector, comprise the punch 3 that is connected with punch seat board 2 by die shank 1, the die of forming by patrix 41 and counterdie 42 4, the front end of described punch 3 is the extrusion molding face of cylindrical convex surface, described die 4 comprises the forming cavity that is made of shaping inner chamber 43 and assist formation inner chamber 44, wherein, the inwall of shaping inner chamber 43 1 ends is provided with the grooving 45 that matches with the extrusion molding face of punch 3, this end is communicated with assist formation inner chamber 44 and crossing edge is saddle-shaped curve, the pressurized forming face of assist formation inner chamber 44 for matching with the extrusion molding face of punch 3.The other end of described shaping inner chamber 43 is provided with locating ring 5.The cylindrical concave surface of described pressurized forming face.The front end of described punch 3 is provided with the guiding correcting block 6 that is used to lead and proofreaies and correct the part flange height that is formed, and this guiding correcting block 6 is used for the guiding of punch 3 early stage being shaped, and is used to proofread and correct the height of part flange of being formed in the later stage that is shaped, and guarantees that it is in error range.
During use, at first, after punch 3, patrix 41 and counterdie 42 are opened respectively, put into counterdie 42 bodies with to be formed, and the location.The starting device switch closes up patrix 41 and counterdie 42 earlier then, punch 3 is closed up again, and the extrusion molding face of punch 3 pushes mutually with the inwall of the forming cavity of die 4, and to be formed port is formed.Punch 3 is return at last again, carried on the patrix 41, opening and taking out drip molding is saddle curve tube connector 7.
