Description
Technical Field
The utility model provides a circle plate-shaped blank positioner that punches a hole belongs to metal stamping technical field.
Background
At present, the spoke of the motor vehicle is finished by adopting a stamping process, the spoke adopts a thicker steel plate as a raw material, firstly a circular blank is cut by utilizing a gas cutting mode, and then stamping forming is carried out on stamping equipment. During stamping, the blank and the die must be concentric. The pre-hole punching positioning mode adopts positioning disc positioning, the positioning disc is matched with the female die, and the size of the positioning disc is matched with the outer diameter of a workpiece, so that the workpiece is accurately positioned. However, because the outer circle of the blank is formed by gas cutting, the surface roughness is poor, and accumulated lumps exist frequently, so that the workpiece can not be placed into the positioning disc frequently, the blank and the female die can not be concentric, waste products are formed during stamping, and the production progress is severely restricted.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's not enough, provide a gas cutting plectane blank positioner that punches a hole, its simple structure can solve effectively because of gas cutting plectane material surface accumulation tumour, quality are poor, and influence the problem of production.
The problem is solved through following technical scheme:
a punching positioning device for a gas cutting circular plate blank comprises a lower template and a female die, wherein the female die is fixed on the lower template, and the punching positioning device also comprises a hinge rod, a positioning mandrel, a positioning roller, a sliding block and a turntable; the upper end of the positioning mandrel is connected with a positioning roller, the positioning roller is circular, the positioning mandrel is fixed on a sliding block, and the sliding block is embedded in the sliding rail; the positioning mandrel is connected with one end of the hinge rod, and the other end of the hinge rod is hinged with the turntable; the number of the positioning rollers is three, and the three positioning rollers are uniformly distributed.
According to the punching positioning device for the gas cutting circular plate blank, the slide rails are rectangular linear slide rails, and the number of the slide rails is three, and the slide rails are respectively fixed on the panel of the lower template.
According to the punching positioning device for the gas cutting circular plate blank, the handle is arranged on the rotary plate.
According to the punching positioning device for the gas cutting circular plate blank, the three or more cushion blocks are distributed around the female die fixing plate and connected with the lower template through bolts, and the rotary table is connected to the upper surface of the cushion block.
The utility model discloses a turning handle adjusts the position of three registration roller, can satisfy the location of different external diameter's circle sheet material to and then realize the fixed to the circle sheet material. Because the centers of the circular arcs passing through the three positioning rollers are adjusted to be coincident with the circle center of the female die in advance, the circle center of the blank is concentric with the female die. The utility model discloses compare with the mode of changing the positioning disk at present, abandoned the change process, alleviateed intensity of labour. The utility model is simple in operation, safe and reliable, practicality and suitability are strong.
Drawings
Fig. 1 is a top view of the present invention;
fig. 2 is a sectional view of the present invention.
In the drawings, the respective reference numerals denote: 1. the die comprises a lower template, a female die, a rotary table, a sliding block, a hinge rod, a positioning core shaft, a positioning roller, a handle, a sliding rail and a cushion block, wherein the lower template comprises 2 parts of a female die, 3 parts of a rotary table, 4 parts of a sliding block, 5 parts of a hinge rod, 6 parts of a positioning core shaft, 7 parts of a positioning roller, 8 parts.
Detailed Description
Referring to fig. 1 and 2, the principle evenly distributed that the registration roller 7 adopted the center of a circle of three points is in the three position of carousel, and every registration roller 7 differs 120, puts the blank on die 2, through promoting handle 8, drives carousel 3, makes the three registration roller linkage of being connected with carousel 3, and three registration roller moves to centre of a circle direction along the slide rail, promotes the work piece and carries out the center location, guarantees the concentricity of blank and mould die.
The utility model discloses in slide rail 9 when having guaranteed that registration roller 7 is the motion of retreating that gos forward along the linear direction, also reduced frictional force for registration roller 7's removal, saved staff's strength.
The utility model discloses in cushion 10 aim at keep carousel 3 and hinge bar 5 on same water flat line, and then realize the accurate positioning to the blank.
