Automatic punching device of vehicle door outer pressing bar

Abstract

Disclosed is an automatic punching device of a vehicle door outer pressing bar. The automatic punching device of the vehicle door outer pressing bar comprises a rack, the rack comprises an upper layer rack and a lower layer rack, a descending station is arranged at one end of the upper layer rack, an ascending station is disposed at the other end of the upper layer rack, a material pick-and-place station, a plurality of punch dies and at least one or more reserved station are sequentially disposed between the ascending station and the descending station, the automatic punching device further comprises a clamping device and a claming driving mechanism, a descending mechanism and a descending driving mechanism are mounted on the lower layer rack located below the descending station, an ascending mechanism and an ascending driving mechanism are disposed on the lower layer rack located below the ascending station, a conveying belt and a conveying belt driving mechanism are disposed between the descending mechanism and the ascending mechanism, one end of the conveying belt, which is close to the descending mechanism, is provided with a first saw cutting mechanism, and one end of the conveying belt, which is close to the ascending mechanism, is provided with a second saw cutting mechanism. The automatic punching device of the vehicle door outer pressing bar has the advantages that the operation is convenient, the repeatability of the produced outer pressing bar is good, the machining accuracy and the machining efficiency are high, and the costs are low.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an automatic punching device for inner and outer beading of a car door. Background technique [0002] The outside bead of the car door is one of the important parts of the car, and the quality of this part directly affects the customer's perception of the quality of the car. In the production process, the outer bead of the car door needs to be punched and sawed. If there is a gap or a shape on the outer bead that needs to be made, a pair of molds are needed for punching. There are multiple gaps or If there are multiple shapes, then multiple sets of molds are required for heavy punching. After punching, both ends of the outer bead need to be sawed, and the process is very complicated. At present, the production of the outer bead is processed manually, punching dies and sawing mechanisms. Each processing needs to be positioned, and the positioning is done manually. Every time ...

Problems solved by technology

In the production process, the outer bead of the car door needs to be punched and sawed. If there is a gap or a shape on the outer bead that needs to be made, a pair of molds are needed for punching. There are multiple gaps or If there are multiple shapes, then multiple sets of molds are required for heavy punching. After punching, both ends of the outer bead need to be sawed, and the process is very complicated.

At present, the production of the outer bead is processed manually, punching dies and sawing mechanisms. Each processing needs to be positioned, and the positioning is done manually. Every time each person positions it There are certain errors, and the repeatability of the external bead completed by the sawing mechanism or punching die each time is poor, which can easily affect the customer's sense of use

Although it is processed by a punching die and a sawing mechanism, the efficiency of manual positioning is also very low, especially when the number of gaps on the outer bead is large or the shape is diverse, the greater the error of the outer bead produced, the easier it is to use When problems occur, customer complaints will also increase, and the repair rate will increase. At the same time, when there are multiple gaps or multiple shapes, multiple employees are required to complete the production of an outer bead, which is not only inefficient, but also high labor costs.
