The automobile exhaust pipe consists of an air inlet joint 4, a corrugated pipe 5 and an air outlet joint 6. The utility model discloses the use of frock makes the course of working replace traditional welding process, can not only realize the synchronous withholding that blast pipe both ends connect, has still improved assembly efficiency, has reduced manufacturing cost, withholds effectual moreover, has improved the connection quality of car pipeline.
Description
Technical Field
The utility model relates to an automobile parts makes the field, especially relates to a frock that car thin wall pipe withheld.
Background
With the continuous development of the automobile industry, the quality pursuit of automobile parts is higher and higher. The automobile exhaust pipe is mostly made of stainless steel, the pipe wall is usually thin (generally below 2 mm), and the automobile exhaust pipe is composed of a corrugated pipe, an air inlet joint and an air outlet joint. The existing bellows and the access joint are usually welded together by laser welding and then brazed. However, the precision of the assembly size is difficult to control by the forming process of the thin-wall pipe, so that quality problems such as poor welding, desoldering, leakage of the exhaust pipe and the like are easily caused.
Disclosure of Invention
In order to avoid above-mentioned prior art's defect and not enough, the utility model provides a withhold frock of thin wall pipe replaces traditional welding process, can not only realize the synchronous withhold of blast pipe both ends joint, has still improved assembly efficiency, has reduced manufacturing cost, withholds effectual moreover, has improved the connection quality of car pipeline.
The utility model provides a pair of withhold frock of thin wall pipe is by bottom plate 1, lower mould locating plate 2, withhold lower mould 3, riser 7, withhold and go up mould 8, go up mould locating plate 9, sliding location board 10, cylinder connector 11, upper plate 12, cylinder 13, back reinforcing plate 14, preceding reinforcing plate 15, side reinforcing plate 16, sliding location bottom plate 17, slide rail 18 and constitute. The automobile exhaust pipe consists of an air inlet joint 4, a corrugated pipe 5 and an air outlet joint 6. The lower die positioning plate 2 is fixed on the bottom plate 1, and two buckling lower dies 3 are fixed on the lower die positioning plate 2 and correspond to the buckling upper dies 8 up and down. The upper buckling mould 8 is fixed on the upper mould positioning plate 9 and is connected with the sliding positioning plate 10. The slide positioning plate 10 is fixed on the slide positioning bottom plate 17 and can slide up and down repeatedly through the slide rail 18. The cylinder 13 is fixed on the upper plate 12, the cylinder connector 11 is connected with the sliding positioning plate 10 and the cylinder 13, and the cylinder 13 can drive the crimping upper die 8, the upper die positioning plate 9 and the sliding positioning plate 10 to do vertical linear motion through the cylinder connector 11, so that the die assembly of the crimping lower die 3 and the crimping upper die 8 is realized, and the crimping operation is completed. The rear reinforcing plate 14 is used for reinforcing the connection between the fixed bottom plate 1 and the vertical plate 7, the front reinforcing plate 15 is used for reinforcing the connection between the fixed sliding positioning plate 10 and the sliding positioning bottom plate 17, and the side reinforcing plate 16 is used for reinforcing the connection between the fixed upper plate 12 and the vertical plate 7.
The utility model discloses the beneficial effect of frock: the novel assembling mode of the automobile exhaust corrugated pipe is low in cost compared with the traditional welding process, flexible to operate and good in buckling effect, the connecting quality of automobile pipelines is improved, and the qualified rate is greatly improved.
Drawings
Fig. 1 is the utility model discloses frock structure schematic diagram.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Firstly, the utility model discloses frock is made and is examined after accepting qualified, fixes its installation on professional equipment, through detecting qualified back, just can withhold work. The process personnel formulate a corresponding operation instruction book, wherein the specific operation steps, parameters and the like of the station are explicitly displayed.
As shown in fig. 1, when the corrugated pipe buckling operation is performed, an operator firstly places the air inlet joint 4, the corrugated pipe 5 and the air outlet joint 6 at corresponding positions of the tool, and then starts an equipment button. The cylinder 13 drives the crimping upper die 8, the upper die positioning plate 9, the sliding positioning plate 10 and the sliding positioning bottom plate 17 through the cylinder connector 11, and moves downwards along the sliding rail 18, so that the lower die 3 and the upper die 8 are crimped, the teeth of the upper die and the lower die are crimped on parts, the product parts are locally deformed, the clearance fit is changed into interference fit, and the corrugated pipe is connected with other parts. After the buckling, the cylinder 13 retracts upwards to drive the buckling upper die 8, the upper die positioning plate 9, the sliding positioning plate 10 and the sliding positioning bottom plate 17 to move upwards along the sliding rail 18, an operator takes down the buckled product to check whether the buckling is firm or not, and the buckling work is finished.
