Abstract
The utility model provides an automatic cutting-off device in a material strip mold of a wiper, which consists of a punch, a cylinder, a spring and a plunging port, wherein the cylinder is mounted on the side surface of a fixed plate of a punching mold, the top end of the punch and the top end of a piston rod of the cylinder are correspondingly mounted in the fixed plate of the punching mold above the automatic cutting-off device, one end with the small diameter of the spring, sheathed at the upper part of the punch, is arranged in the fixed plate, and a concave die of the plunging port is arranged on the edge at the outer end of a lower template of the punching mold which is arranged at the lower part of the automatic cutting-off device. The adoption of the structure of arranging the automatic cutting-off device in the punching mold can automatically cut off a punched material strip of a punched product when completing the punching process, thereby greatly reducing the labor intensity of production.
Description
Technical field
The utility model relates to window, windshield or the similar device of vehicle, is meant automatic disconnecting device in a kind of rain brush strip mould especially.
Background technology
Windshield wiper is to be installed on being used for scraping rainy day and sweeping the car windscreen rainwater so that help human pilot to see the requisite device of road clearly of car windscreen.Existing rain brush production is mainly adopted press machine to carry out punch process and is made, because punching press rear windscreen wiper strip mostly adopts manual cutting off, operation labour intensity is big, production efficiency is low, is unfavorable for that manufacturing enterprise raises labour productivity, saves production cost.
Summary of the invention
Technical problem to be solved in the utility model just is to overcome the defective that existing rain brush production Sheet Metal Forming Technology exists, and automatic disconnecting device in a kind of rain brush strip mould that the automatic disconnecting device structure is set in the diel of rain brush production is provided.
Automatic disconnecting device is made up of drift, cylinder, spring and the following edge of a knife in the rain brush strip mould of the present utility model, cylinder is installed in the fixed head side of diel, the drift top is corresponding with the cylinder piston rod top to be installed in the diel fixed head of automatic disconnecting device top, spring housing is loaded in the fixed head at minor diameter one end on drift top, and following edge of a knife die is loaded on the diel lower bolster outer end edges of automatic disconnecting device bottom.Cylinder diameter is φ 10mm, operating pressure 0.5MPa, and piston stroke 3-8mm, cylinder is 65-70mm at the total length that piston rod stretches out shape; The spring length of static shape is 10mm.
Automatic disconnecting device can realize that strip cuts off automatically according to needed product length in the rain brush strip mould, during punching operation, strip passes mould, behind the closed number of times of mould through regulation, counter sends signal, and gas circuit is connected, and drift is ejected by cylinder piston rod, when patrix is descending, at drift be fixed under the acting in conjunction of the following edge of a knife on the lower bolster and cut off strip; When patrix was up to peak, counter sent signal, and gas circuit is closed, and cylinder piston rod is return, and drift is withdrawn into initial position under the effect of spring force.
Advantage of the present utility model just is simple in structure, adopted the structure that automatic disconnecting device is set in diel, the punching press strip of stamping products can when finishing, punching course be cut off automatically, greatly reduce productive labor intensity, further improve labor productivity and production efficiency, saved production cost.Thereby automatic disconnecting device has broad prospect for its application in the rain brush strip mould of the present utility model.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing;
Fig. 1 is the structural representation of automatic disconnecting device in the utility model rain brush strip mould.
With reference to accompanying drawing, 1, drift, 2, cylinder, 3, spring, 4, the edge of a knife down; Letter b is the cylinder air inlet, and A is the inblock cylinder gas port, and C is the diel fixed head, and D is the diel lower bolster.
The specific embodiment
Below be embodiments of the invention, the actual use of the present invention is not limited to embodiment.
Embodiment 1, automatic disconnecting device in the rain brush strip mould
Adopt the interior automatic disconnecting device of rain brush strip mould of the utility model structure.Consult accompanying drawing, automatic disconnecting device is made up of drift 1, cylinder 2, spring 3 and the following edge of a knife 4 in the rain brush strip mould, cylinder 2 is installed in the fixed head C side of diel, drift 1 top is corresponding with the cylinder piston rod top to be installed in the diel fixed head C of automatic disconnecting device top, minor diameter one end that spring 3 is enclosed within drift 1 top is loaded in the fixed head C, and the following edge of a knife 4 dies are loaded on the diel lower bolster D outer end edges of automatic disconnecting device bottom.Cylinder diameter is φ 10mm, operating pressure 0.5MPa, and piston stroke 3-8mm, cylinder is 65-70mm at the total length that piston rod stretches out shape; The spring length of static shape is 10mm.
Original rain brush is produced pressing equipment to be transformed, draw the Air Valve Control line in PLC from the press machine electrical control cabinet (full name Programmable Logic Controller the is a Programmable Logic Controller) lead-out terminal, adjusting the PLC program increases the control program that strip cuts off automatically, with the logic basis of lathe down stroke number as the connection of Air Valve Control line terminals.During punching production, strip passes mould, and behind the closed number of times of mould through regulation, counter sends signal, and gas circuit is connected, and drift is ejected by cylinder piston rod, when patrix is descending, at drift be fixed under the acting in conjunction of the following edge of a knife on the lower bolster and cut off strip; When patrix was up to peak, counter sent signal, and gas circuit is closed, and cylinder piston rod is return, and drift is withdrawn into initial position under the effect of spring force.Length that so just can be as required realizes the automatic cut-out of strip.
Operating position is good.
