Abstract
The utility model relates to an edge-coiling machining die, in particular to a railway-vehicle sliding-plug-door hinge edge-coiling molding die, belonging to the edge-coiling die technological field. The railway-vehicle sliding-plug-door hinge edge-coiling molding die is composed of a pre-bending head die and a hinge molding die. The pre-bending head die consists of an upper module and a low module. The lower surface of the upper module has a wedge-shaped flange, and the upper surface of the lower module has a groove buckled with the wedge-shaped flange. A positioning baffle plate is disposed at the outer side of the lower module. The hinge molding die is composed of an oil-hydraulic-press pressure head and a lower molding die. The lower molding die has a step shape with an upper step and a lower step. A bean sprout-shaped groove is provided at a position where the upper step and the lower step are connected, with the large end thereof being downwardly oriented. The utility model has the beneficial effects that the railway-vehicle sliding-plug-door hinge edge-coiling molding die, with a simple structure, is convenient to operate and allows edge-coiling treatment of medium and heavy plates with a thickness greater than 3 mm; and a hinge bore has good roundness and is not likely to change abruptly, thereby guaranteeing the free rotation of a hinge rotating shaft, improving the production efficiency and the yield rate and reducing the production cost.
Description
Technical field
The utility model relates to a kind of volume circle processing mold, and especially a kind of rail truck plug sliding door hinge coiling mould belongs to volume circle technical field of mold.
Background technology
In the railway transportation, the hinge that connects rail truck plug sliding door needs the sheet bending moulding to make usually, but therefore the general easy mistake circle of the workpiece that manually-operated obtains need be rolled up circle to sheet material and handle, to satisfy the needs of hinge operate as normal.In the existing volume circle technology, the mode of the flexible normal employing of volume of hinge is: the end of locating piece and plug interaction clamping sheet material at first is the center then with the plug, and the rolling through spheronizator makes workpiece along the circumferential direction move, and realizes the round moulding of volume.Yet this method is only applicable to the sheet material of thickness less than 3mm, for thickness greater than among the 3mm, heavy-gauge sheeting uses this method to roll up bowlder; Because sheet material is thicker relatively; It is bigger to add the resistance that runs into man-hour, makes the sheet material sudden change of sliding easily, thereby causes the hinge endoporus to lose circle; The product defect rate is high, and production efficiency is low.
The utility model content
The purpose of the utility model is: to the problem that above-mentioned prior art exists, proposes a kind of simple in structurely, can the centering heavy-gauge sheeting roll up circle and handle, and the high rail truck plug sliding door hinge coiling mould of yield rate.
In order to reach above purpose; The rail truck plug sliding door hinge coiling mould of the utility model is made up of pre-bending head mould tool and hinge mould, and its improvements are; Said pre-bending head mould tool is made up of upper module and lower module; The lower surface of said upper module has wedge-shaped bead, and the upper surface of said lower module has the groove that is interlocked with wedge-shaped bead, and the outside of said lower module has positioning baffle; Said hinge mould is made up of hydraulic press pressure head and compacted under mould, and it is stepped that said compacted under mould goes to upper and lower two-stage, and the junction of said upper and lower ladder is shaped on big end bean sprouts shape (both J-shapeds) groove down.
The utility model further improves, and a side angle of said wedge-shaped bead is an arc angle, is cambered surface with the corresponding side of the arc angle of wedge-shaped bead on the said groove.
The utility model further improves, and the downstairs of said compacted under mould is provided with the backstop that clamps push rod and match with the clamping push rod.
The beneficial effect of the utility model is: the rail truck plug sliding door hinge coiling mould of the utility model, and simple in structure, easy to operate; Can accurately and easily roll up circle greater than the cut deal material of 3mm to thickness and handle, make that the flap after the moulding can meet design requirement well, and the circularity of hinge endoporus be better; Be difficult for undergoing mutation; Thereby the rotating shaft that has guaranteed hinge rotates freely, and has improved the yield rate of production efficiency and product, has reduced production cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the pre-bending head mould of the utility model structure sketch map of signing an undertaking.
Fig. 2 is the hinge forming die structure sketch map of the utility model.
The specific embodiment
Embodiment one
The rail truck plug sliding door hinge coiling mould of present embodiment; Structure is as depicted in figs. 1 and 2, is made up of pre-bending head mould tool and hinge mould, and wherein pre-bending head mould tool is made up of upper module 1 and lower module 2; The lower surface of upper module 1 has wedge-shaped bead 4; The upper surface of lower module 2 has the groove 5 that is interlocked with wedge-shaped bead 4, and a side angle of wedge-shaped bead 4 is an arc angle, is cambered surface with the corresponding side of the arc angle of wedge-shaped bead on the groove 5; The outside of lower module 2 has positioning baffle 3, and promptly positioning baffle 3 is set in place in the prominent edge in the lower module 2 upper groove cambered surfaces outside last.The hinge mould is that the hydraulic press pressure head 6 of inverted T shape is formed with compacted under mould 7 by the cross section; It is stepped that compacted under mould 7 goes to upper and lower two-stage; The junction of upper and lower ladder is shaped on big end bean sprouts shape (both J-shapeds) groove 8 down, and on downstairs, is provided with the backstop 10 that clamps push rod 9 and match with clamping push rod 9.
During real work; This hinge coiling mould utilizes pre-bending head mould tool that rake angle and bending are carried out in the end of workpiece; Suppress the one section elbow identical with the hinge diameter, this elbow can form guiding in follow-up hinge forming process, and guarantees the shape and the size of hinge end.Simultaneously; In the backstop 10 of hinge mould and clamp under the acting in conjunction of push rod 9; The workpiece that pre-bending is good is fixed on the hinge mould; The elbow that guarantees workpiece sinks in the bean sprouts connected in star 8 of hinge mould, and hydraulic press pressure head 6 is exerted pressure by the top and made workpiece utilize the brake forming in the connected in star of bean sprouts that is directed at of elbow, processes hinge.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
