Abstract
The invention discloses an improved structure of a radiator pipe gate drawing die, belongs to a drawing die, and aims at providing the pipe gate drawing die which can form horizontal lap joint teeth at the left end of a pipe gate and the right end of the pipe gate through one-time drawing forming. The improved structure comprises a drawing male die fixed to an upper die plate, and a drawing female die fixed to a lower die plate. A T-shaped sliding groove (8) communicated with a female die cavity (9) is formed in the drawing female die (1). A movable insert (5) matched with the sliding groove is arranged in the sliding groove. A screw (4) connected with the movable insert is arranged below the movable insert. The screw is ejected by a spring (3) fixed into the lower die plate (2). The improved structure overcomes the defect that an outward-turned flange can not be formed through an existing drawing die, has the advantages of being simple in structure, convenient to use, high in efficiency and the like, and is used for the drawing die of the radiator pipe gate.
Description
Technical field
The present invention relates to a kind of Drawing Die, relate in particular to a kind of radiator tube grid Drawing Die and improve structure.
Background technology
Pipe grid are for sealing the vitals of radiator water chamber.The edge of pipe grid, with some rectangular teeths that are square-wave-shaped, can seal 90 ° of the inside bendings of this rectangular teeth by hydroecium rivet clasp by Special riveting frock when pipe grid and hydroecium fastening.Yet, due to positioning datum not being set, usually cause pipe grid and hydroecium dislocation, cause leaking.Occurred that a kind of two ends, left and right at pipe grid are with the New pipe grid of a level overlap joint tooth of outwards routing up for this reason, utilized this level overlap joint tooth can realize the accurate location between pipe grid and hydroecium, thereby guarantee hydroecium positiver sealing.Yet because the two ends, left and right at pipe grid have increased level overlap joint tooth, pipe grid Drawing Die originally can not be used, and need to carry out reasonable reformation to it.
Summary of the invention
In order to overcome the defect existing in prior art, the present invention aims to provide the radiator tube grid Drawing Die improvement structure that a kind of once drawing and forming can form at pipe two ends, grid left and right level overlap joint tooth.
To achieve these goals, the present invention by the following technical solutions: it comprises the pull and stretch punch that is fixed on cope match-plate pattern, is fixed on the pull and stretch die on lower bolster; On pull and stretch die, have the T font chute being communicated with concave die cavity, have adaptive with it loose plug in this chute, there is the screw being attached thereto the below of this loose plug, and this screw is by the spring top clamping being fixed in lower bolster.
Compared with the prior art, the present invention is owing to having adopted technique scheme, on the basis of original structure, increased T font chute, and in this chute, increased the loose plug by spring top clamping, therefore the level overlap joint tooth that can outwards rout up in one of each self-forming of two ends of pipe grid in once drawing and forming process, has solved the defect that original drawing die cannot form the flange that turns up.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that A in Fig. 1 is to view;
Fig. 3 is the pipe grid structural representation with level overlap joint tooth;
Fig. 4 is the top view of Fig. 3.
In figure: pull and stretch die 1, lower bolster 2, spring 3, screw 4, loose plug 5, plate 6, pull and stretch punch 7, chute 8, concave die cavity 9, level overlap joint tooth 10, workpiece 11.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As shown in Fig. 1～4: pull and stretch punch 7 is fixed in cope match-plate pattern (not shown), there is the pull and stretch die 1 being fixed on lower bolster 2 below of pull and stretch punch 7; There is the T font chute 8 being communicated with concave die cavity 9 on the surface of this this pull and stretch die, has the adaptive with it loose plug 5 that can slide up and down in this chute; There is the screw 4 being attached thereto the below of this loose plug, and this screw is held out against by the spring 3 being fixed in lower bolster 2.
Operation principle: while forming disk-like structure when being placed in that the surperficial plate 6 of pull and stretch die 1 is pressed into pull and stretch die 1 concave die cavity 9 by pull and stretch punch 7, the level at two ends, left and right overlap joint tooth 10 is out of shape and is upturned; When pull and stretch punch 7 continues to move downward, level overlap joint tooth 10 is pressed between pull and stretch die 1 and loose plug 5 and the flange that formation is outwards routed up gradually; When pull and stretch punch 7 promotes that loose plugs 5 move downward and while touching pull and stretch die 1, level overlap joint tooth 10 just can be flattened by pull and stretch punch 7 and pull and stretch die 1.When pull and stretch punch 7 rises, loose plug 5 by screw 4 spring 3 by upwards jack-up and discharging of workpiece 11 (pipe grid).
Claims (1)
1. radiator tube grid Drawing Die is improved a structure, comprises the pull and stretch punch that is fixed on cope match-plate pattern, is fixed on the pull and stretch die on lower bolster; It is characterized in that: on pull and stretch die (1), have the T font chute (8) being communicated with concave die cavity (9), in this chute, there is adaptive with it loose plug (5), there is the screw (4) being attached thereto the below of this loose plug, and this screw is held out against by the spring (3) being fixed in lower bolster (2).
