Description

The general fitting device of self-clinching stud

Technical field

The utility model relates to the device of self-clinching stud.

Background technology

In automotive field, the screw fitting device that presses is generally fixed (only being applicable to a kind of public rail prepackage, perhaps a kind of female rail rail prepackage such as the width of cloth frock that presses).One width of cloth fitting device can not be taken into account the public affairs of other types simultaneously, and female rail screw presses or the screw of other parts presses.When producing according to the frequent die change of the different needs of product and wasteful time (particularly sample stage: wide in variety, amount is few again).

The utility model content

The purpose of the utility model is to provide a kind of self-clinching stud general fitting device, and it has good versatility.

For the general fitting device of the self-clinching stud of realizing said purpose, be characterized in, comprise upper die and lower die, the pressure head of on patrix, installing, the pedestal of on counterdie, installing that presses, be installed in liftout in the pedestal that presses, be installed in the pressing mold pedestal core rod, disk spring and be installed in the lead between the upper die and lower die; Pressure head is fixedly mounted on the patrix through locating piece adjustably; The pressing mold pedestal also is fixedly mounted on the counterdie through locating piece adjustably, and the pressing mold pedestal has cavity, places disk spring in the cavity; The lower end of liftout is inserted in the center of disk spring and is accepted by disk spring; Core rod is fixed on the pressing mold pedestal and is positioned at the top of this cavity, and liftout interts the endoporus of core rod from the lower end of core rod, and there is the perforation that connects this endoporus the upper end of core rod; This perforation is used to receive screw; Lead is installed between the upper die and lower die, and the lower end of lead is fixed on the counterdie, and the upper end is received by the pilot hole of patrix.

Patrix is descending, and pressure head presses down screw, so that screw is pressed in the workpiece; The head of screw and the head of liftout are replaced; Give the disk spring imposed load, patrix is up subsequently, accomplishes the discharge process of screw in the effect of disk spring; The screw that this structure is fit to most part presses, and has good versatility.

Description of drawings

Fig. 1 is the stereogram of the general fitting device of self-clinching stud.

Fig. 2 to Fig. 4 is the cutaway view of cutting open along the broken line A-A-A among Fig. 1, and wherein Fig. 2 is the descending sketch map of patrix, and Fig. 3 is the sketch map of the process of pressing, and Fig. 4 is the up sketch map of patrix.

The specific embodiment

To shown in Figure 4, the general fitting device of self-clinching stud comprises patrix 1, counterdie 2 like Fig. 1, at the pressure head of installing on the patrix 16, at the liftout of installing on the counterdie 24, be installed in core rod and disk spring 5 on the counterdie 2.

Counterdie 2 is installed with the pedestal 9 that presses through each locating

piece

21,22,8 etc., and the pedestal 9 that presses has cavity, places disk spring 5 in the cavity; Liftout 4 is column, and its lower end is inserted into the center of disk spring 5, and if liftout 4 is descending; Will imposed load to disk spring 5 so that disk spring 5 distortion, disk spring 5 correspondingly applies reaction force to liftout 4; It can make liftout 4 up after discharging external force, in embodiment as shown in Figure 2, disk spring 5 be with liftout 4 on radially boss interact; The below of disk spring 5 is porose, can supply the lower end of liftout 4 to insert, to increase the descending stroke of liftout 4.

The outside of liftout 4 is with core rod 3; Core rod 3 is removably to be fixedly mounted on the pedestal 9 that presses; Be positioned at aforementioned cavity top, core rod 3 has the endoporus that receives liftout 4, and there is perforation the upper end of core rod 3; Perforation and endoporus communicate, and the screw 31 that passes workpiece 32 (for example being female rail or public rail) penetrates and touch the top of liftout 4 downwards from this perforation.

Pressure head 6 is installed on the patrix 1, and pressure head 6 has protuberance, and this protuberance can be inserted in the workpiece 32, to touch screw 31.As shown in Figure 2, pressure head 6 also is to be fixed on the patrix 1 adjustably and removably through each locating

piece

12,11 etc.

Between patrix 1 and the counterdie 2 lead 7 is installed, lead 7 is fixed on the counterdie 2, and patrix 1 has perforation 13 to receive lead 7; Lead 7 can slide in perforation 13; The outside of lead 7 is with back-moving spring 71, and counterdie is in descending process, and back-moving spring 71 is compressed; Counterdie is in up process, and the spring force of back-moving spring 71 helps to make patrix 1 to quickly recover to initial position.

To shown in Figure 4, the general fitting device of this self-clinching stud is according to the difference of workpiece 32 like Fig. 1, and the difference of screw 31 positions is regulated pressure head 6 (horizontal direction, longitudinal direction); And regulate the pedestal 9 (horizontal direction or longitudinal direction) that presses.

As shown in Figures 2 and 3, the patrix 2 descending binders that carry out.Mould presses down and makes screw 31 be pressed into part 32.Screw 31 heads withstand liftout 4 loads disk spring 5.

As shown in Figure 3, pressure head 6 rises and is applied to the power unloading on the screw 31.Disk spring 5 resets to make on the liftout 4 and lifts, and cooperates the appropriate diameter of core rod 3, thereby accomplishes the discharge process of screw 31.

The diameter of the perforation through core rod 3 in the binder process is eliminated screw 31 and has been pressed later burr, improves the distortion that part should press and produce through the angles on core rod 3 surfaces.
