Abstract

The invention discloses a riveting and decompressing tool for a windshield wiper arm of an automobile and with a dimpling connection structure. A bracket is placed on a tool inner core block and positioned; a fork-shaped piece is driven to move by an upper die plate, and transfers force to two slide blocks through an angle surface C and an angle surface D to push the slide blocks to move in a groove of a base simultaneously and oppositely, so that the bracket is decompressed and wrapped on an arm rod; the fork-shaped piece descends continuously; the slide blocks stop moving and enter a pressure maintaining stage; the upper die plate drives a punch to dimple on the decompressed bracket till the upper die plate is contacted, closed and limited with the slide blocks; at the moment, a closed cavity is formed at a windshield wiper arm component by the left and right slide blocks and the core block; a riveting part of the windshield wiper arm component is adjusted and shaped; a spring bounces up the upper die plate and the fork-shaped piece after an equipment return stroke external force is removed; slide block springs push the slide blocks away from the core block; the windshield wiper arm component is taken out freely; and riveting is accomplished. When riveting and dimpling are accomplished, a riveting structure is shaped; the product quality is ensured; decompressing and dimpling of the bracket of a windscreen windshield wiper and the arm rod can be accomplished simultaneously by one-step clamping; and the working efficiency is high.

Description

Rush the riveted joint of nest syndeton automobile wiper arm and receive the pressure frock

Technical field

The present invention relates to the automobile wiper arm riveted joint and receive the pressure frock, particularly a kind of nest syndeton automobile wiper arm riveted joint receipts of rushing are pressed frock.

Background technology:

Receive the scraping arm processing that pressure is rushed the nest syndeton for wiper bracket (arm plate), armed lever, the prior art scheme is:

Figure 2012104976875100002DEST_PATH_IMAGE002

Utilize first hydraulic press to press frock to receive riveting wiper bracket (arm plate), the connection of armed lever realization parcel with being connected;

Figure 2012104976875100002DEST_PATH_IMAGE004

And then by vice or other special-purpose locking fixture under the condition that arm plate, armed lever parcel is good, to wiper bracket (arm plate) in the pcketing of armed lever hole site.This scheme is complex process not only, and inefficiency, and product quality is difficult to guarantee, is not suitable for batch production.

Summary of the invention:

The objective of the invention is: design a frock, only need clamped one time, can finish simultaneously wiper bracket (arm plate), armed lever receipts pressure and arm plate and rush nest.

Namely this frock is by the inclined sliding block structure power transmission, and cope match-plate pattern drives fork-shaped piece (having angle faces), utilize angle faces up and down vertical stroke be converted into the transverse movement of left and right sides slide block, receive and press the parcel motion.Continue descendingly, receive to press the package structure pressurize, cope match-plate pattern drives drift and finishes the nest that rushes to wiper bracket (arm plate).At last, the frock closure is spacing, and proofreaies and correct shaping to receiving riveting.

Formation of the present invention: a kind of nest syndeton automobile wiper arm riveted joint receipts of rushing are pressed frock, by cope match-plate pattern, guide pillar, slide block, Y-piece, spring, support, armed lever, base, drift, pellet and sliding block spring form, it is characterized in that: stentplacement pellet in frock is located, drive the left and right sides Y-piece motion with certain angle by cope match-plate pattern, this Y-piece is by angle faces C, D passes to the left and right sides slipper push slide block that has equally with the Y-piece angle automatching with power and moves in the groove of base, two slide blocks simultaneously move toward one another are wrapped in support receipts pressure on the armed lever, until angle part finishes, Y-piece continues descending, the slide block stop motion enters packing stage, cope match-plate pattern drives drift pcketing on the support of receiving after pressing, until that cope match-plate pattern contacts with slide block is closed spacing, form enclosed cavity by left and right sides slide block and pellet scraping the arm component place this moment, and the scraping arm assembly staking is partly proofreaied and correct shaping; Equipment backhaul external force is removed rear spring cope match-plate pattern and Y-piece is upspring, and sliding block spring pushes away pellet with slide block, scrapes arm component and freely takes out, and finishes the receipts riveting.

Compared with the prior art, the present invention has the following advantages:

1, this frock changes the Y-piece design on the basis of original receipts riveting tool, increases positioning guide column and rushes the nest drift, and tool structure is simple, and working service is easy.

2, Y-piece is designed to angle faces and straight flange face two parts, carries out shaping to receiving the riveting knot structure when finishing the receipts riveting, rushing nest.Both guarantee the attractive in appearance of profile, and greatly reduced again to receive the scraping arm torsional angle distortion that compressive strain causes, guaranteed product quality.

3, clamped one time can be finished simultaneously wiper bracket, armed lever receipts pressure and rush nest, and operating efficiency is improved.

The specific embodiment:

Shown in Fig. 1-11, a kind of nest syndeton automobile wiper arm riveted joint receipts of rushing are pressed frock, by cope match-plate pattern, guide pillar, slide block, Y-piece, spring, support, armed lever, base, drift, pellet and sliding block spring form, it is characterized in that: support 6 is placed in the frock and locates on the pellet 10, drive left and right sides Y-piece 4 motions with certain angle by cope match-plate pattern 1, this Y-piece 4 is by angle faces C, D passes to the left and right sides slide block 3 promotion slide blocks that have equally with the Y-piece angle automatching with power and moves in the groove of base 8, two slide blocks 3 simultaneously move toward one another are wrapped in support 6 receipts pressures on the armed lever 7, until angle part finishes, Y-piece 4 continues descending, slide block 3 stop motions enter packing stage, cope match-plate pattern 1 drives drift 9 pcketing on the support 6 of receiving after pressing, until that cope match-plate pattern 1 contacts with slide block 3 is closed spacing, form enclosed cavity by left and right sides slide block 3 and pellet 10 scraping the arm component place this moment, and the scraping arm assembly staking is partly proofreaied and correct shaping; Equipment backhaul external force is removed rear spring 5 cope match-plate pattern 1 and Y-piece 4 is upspring, and sliding block spring 11 pushes away pellet 10 with slide block 3, scrapes arm component and freely takes out, and finishes the receipts riveting.
