Abstract
Door of elevator manufacturing technology field is the utility model is related to, more particularly to a kind of connecting mold of door of elevator corner.A kind of door of elevator corner designed by the utility model is without riveting connecting mold, including mold and lower mould, mold relative lower dies vertical up-or-down movement；The lower end of mold is punch, and the lower end of punch is arc surface, and the upper end of lower mould is top, and top both sides are equipped with blade, and blade is connected by spring screw with lower die head clamping piece；The top is overlapped positioned at the underface of punch, the center line of top with the center line of punch, and blade coordinates with top for non-gap, and the height of blade is higher than top.Flanging is come directly towards the resistance of upward supporting role and two side blades by lower mould at the same time during punching press, flanging, which is formed down, to be recessed and gradually extends to both sides, so that the thickness of flanging is slowly thinning, two pieces of flangings are firmly bonded together due to material ductility itself up and down after reaching to a certain degree, so as to complete no riveting connection.
Description
Technical field
Door of elevator manufacturing technology field is the utility model is related to, more particularly to a kind of connection mould of door of elevator corner
Tool.
Background technology
Door of elevator is four inside bendings in side by one block of steel plate in process, in the corner of door of elevator position
Put, the flanging of vertical and horizontal needs to link together.Existing processing technology be by two sides by rivet interlacement, by
Needed in rivet interlacement by manual operation, can not realize mechanization and automation, thus high labor cost, low production efficiency.
Connecting mold of the exploitation automation without riveting attachment device is particularly significant to the performance and quality of door of elevator.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided a kind of production efficiency is high, bonding strength is big,
The door of elevator corner that product quality is stablized is without riveting connecting mold.
In order to achieve the above object, a kind of door of elevator corner designed by the utility model is without riveting connecting mold, including
Mold and lower mould, mold relative lower dies vertical up-or-down movement；The mold includes upper die head and upper die head clamps
Part, the upper end of upper die head are connected with upper die head clamping piece, and the lower end of upper die head is punch, and the lower face of punch is arc surface；Institute
Stating lower mould includes lower die head and lower die head clamping piece, and lower die head is fixed in lower die head clamping piece, and the upper end of lower die head is top
Head, top both sides are equipped with blade, and blade is connected by spring screw with lower die head clamping piece；It is described top positioned at punch just under
Side, the center line of top are overlapped with the center line of punch, and blade coordinates with top for non-gap, and the height of blade is higher than top.
In order to avoid abrasion of the punch to steel surface, preferably, the lower end of upper die head is equipped with rubber sleeve, punch is placed in
In rubber sleeve.
To ensure the bonding strength of two flangings, the flanging thickness of junction need to be made very small, therefore preferably, two side tools
The distance between piece is 2mm.
During utility model works, the flanging of door of elevator is between upper/lower die, mold vertical downward movement, on
The downward punching press flanging of punch of mould, flanging is come directly towards upward supporting role and both sides by lower mould at the same time during punching press
The resistance of blade, under the action of three punch, top and blade direction force, flanging, which is formed down, to be recessed and gradually prolongs to both sides
Exhibition so that the thickness of flanging is slowly thinning, reaches two pieces of flangings up and down rear to a certain degree due to material ductility itself
Firmly it is bonded together, so as to complete no riveting connection.
Therefore, it has the characteristics that simple in structure, design is reasonable and easy to use.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of door of elevator corner of the present embodiment description is without riveting connecting mold, including mold and lower die
Tool, mold relative lower dies vertical up-or-down movement；The mold includes upper die head and upper die head clamping piece 1, upper die head
Upper end is connected with upper die head clamping piece, and the lower end of upper die head is punch 2, and the lower face of punch is arc surface；The lower mould bag
Lower die head and lower die head clamping piece 3 are included, lower die head is fixed in lower die head clamping piece, and the upper end of lower die head is top 4, comes directly towards two
Side is equipped with blade 5, and blade is connected by spring screw 6 with lower die head clamping piece；The top is positioned at the underface of punch, top
Center line overlapped with the center line of punch, blade coordinates with top for non-gap, and the height of blade is higher than top, two side blades
The distance between be 2mm；The lower end of the upper die head is equipped with rubber sleeve, and punch is placed in rubber sleeve.
