Abstract

The utility model provides a double-hole hedging die with an automatic discharging suspension arm, which comprises two protruding moulds and a hanging arm sunk mould as well as a material unloading device composed of an overrunning clutch and a material unloading device; wherein, the overrunning clutch is composed of a free gear, a star wheel, a column rotor, a top pin, and a spring; the star wheel is arranged at the center of the free gear; the column rotor and the top which is connected with the spring is arranged inside the space of the star wheel; and the material unloading device is composed of racks meshing with the free gear on the overrunning clutch as well as a material unloading rod and a material unloading board fixed on the star wheel. The clutch device is used for automatic material unloading of the pressed products with a reasonable structure design, a high automatization, and effectively reducing the work intensity of workers; the workpieces are arranged on a bracket of the hanging arm for punching, and the structure of the mould is simple, and two corresponding holes can be punched at the supporting wall in a stroke, which can save the work time with a high efficiency; the products can make the tube material have a plastic deformation with the sunken mould and the protruding mould and prevent pits at the punching places on the products, and the product quality is high.

Description

Automatically the discharging cantilever diplopore mould that liquidates
Technical field
The utility model relates to tubing radially towards the device of diplopore, relates in particular to the diplopore mould that liquidates of the cantilever with automatic discharging.
Background technology
The method in processing type hole mainly is a machining on tubing, comprises boring, hole milling etc.During production in enormous quantities, the hole on the tubing part replaces methods such as boring, hole milling with the method for punching, has the productivity ratio height, advantages such as product surface aesthetic.Simultaneously, the tubing punching does not need special installation, gets final product punching out on general punch press, and mould structure is simple, thereby becomes conventional production technology.At present, the mould of home and abroad tubing punching mainly contains following two kinds:
1, the punching technology in opposite directions of no die is characterized in that tubing does not have die when stamping-out, have only punch.Tubing is in the holding pad forceful action, two in opposite directions under the impact of punch gradually attenuation reach fracture, formation type hole; Its shortcoming is owing to there is not die to support, go out the hole around form pit, only be applicable to that therefore permission is had the part of pit around the punching.
2, the cantilever mould that liquidates, its working part mainly is made up of two punch and a cantilever die.It at first is contained in tubing on the cantilever die, and so latter two punch carries out punching press the other way around, obtains the required type of product hole; Its shortcoming is that after the stamping-out because product punching position deforms, and locking was difficult to take off on the cantilever die after the product punching press was finished.
The content of utility model
At the cantilever of the existing hole punching on circular duct device mould above shortcomings that liquidate, the purpose of this utility model provides a kind of cantilever based on the freewheel clutch discharging with Automatic Charging Device diplopore mould that liquidates.
The purpose of this utility model is achieved in that the cantilever of the automatic discharging diplopore mould that liquidates, comprise two punch and a cantilever die, it is characterized in that: also comprise the device for discharging of forming by freewheel clutch and shedding mechanism, described freewheel clutch is made up of free gear, star-wheel, cylindrical roller, ejector pin and spring, star-wheel is located at the center of free gear, and cylindrical roller and the ejector pin that is connected with spring are located in the space of star-wheel; Described shedding mechanism is by forming with the tooth bar of freewheel clutch free gear engagement, discharge arm and the stripper that is fixed on the star-wheel, and stripper is through on the cantilever die and leans against on the discharge arm.
Described discharge arm is connected with spring and is spacing by spacer pin.
Compared to existing technology, the utlity model has following advantage:
1, adopt clutch apparatus to punching press after product carry out automatic discharging, reasonable in design, the automaticity height effectively reduces working strength of workers;
2, workpiece is installed on the support of cantilever and carries out punching, and mould structure is simple, and one stroke can be gone out two relative holes on barrel, can save man-hour, and efficient is higher;
3, product utilization die and punch make tubing produce plastic deformation simultaneously, have avoided product punching place pit to occur, the product quality height.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the freewheel clutch structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, 2, automatically the discharging cantilever diplopore mould that liquidates, comprise 1,4 and cantilever dies 2 of two punch, also comprise the device for discharging of forming by freewheel clutch and shedding mechanism, described freewheel clutch is made up of free gear 9, star-wheel 10, cylindrical roller 16, ejector pin 17 and spring 18, star-wheel 10 is located at the center of free gear 9, and cylindrical roller 16 and the ejector pin 17 that is connected with spring 18 are located in the space of star-wheel 10; Described shedding mechanism is by forming with the tooth bar 8 of freewheel clutch free gear 9 engagement, discharge arm 11 and the stripper 7 that is fixed on the star-wheel 10, and stripper 7 is located with being through on the cantilever die 2 and leaning against on the discharge arm 11.Described discharge arm 11 is connected with spring 13 and is spacing by spacer pin 12.
Referring to Fig. 2, have the cantilever of freewheel clutch discharging, its freewheel clutch is made up of free gear 9, star-wheel 10, cylindrical roller 16, ejector pin 17 and spring 18.When free gear 9 when tooth bar 8 drives and is rotated counterclockwise, with spring 18 compressions, cylindrical roller is in the maximum interspace place to cylindrical roller 16 by ejector pin 17, star-wheel 10 separates with free gear 9 and does not carry out rotating; When free gear 9 when tooth bar 8 drives and turns clockwise, cylindrical roller 16 is under the effect of the elastic force of spring 18 and frictional force, between free gear and star-like body, gear drives star body by roller and rotates together by wedging.This shows, when the stripper 7 of the utility model device falls, drive the rotation of freewheel clutch and don't rotate, workpiece is pushed away, realized that workpiece drops voluntarily thereby when stripper 7 rises, rotate by the freewheel clutch driven gear as for driven gear 9.
The utility model operating procedure is as follows:
1, pipe fitting 3 is enclosed within on the cantilever die 2, and last punch 4 is descending under the forcing press effect, and holding pad 5 is pushed down cylindrical member;
2, free gear 9 engagements of tooth bar 8 on freewheel clutch are rotated, and star-wheel 10 keeps motionless because freewheel clutch is in the state of separation;
3, along with forcing press is descending, be contained in last punch 4 punching press pipe fittings 3 and cantilever die 2 on the punch retainer 6, make it descending, pipe fitting is pushed down the lower punch 1 that is contained on the lower punch fixed head 15, and cylindrical member 3 is finished punching under last punch 4 and lower punch 1 and 2 actings in conjunction of cantilever die;
4, after stamping-out was finished, last punch 4 and holding pad 5 were up under forcing press drives, and it is up together that tooth bar 8 is followed punch 4, and the free gear 9 and the star-wheel 10 that drive on the freewheel clutch rotate together;
5, discharge arm 11 rotations that are fixed on the star-wheel 10 cause stripper 7 to left movement cylindrical member 3 to be released from cantilever die 2.
6, after the discharging action is finished, tooth bar 8 continues to separate with free gear 9, and discharge arm 11 is got back to initial position at spring 13 and leaned against on the spacer pin 12.
