Description

Technical Field

[0001] The present invention relates to the technical field of stamping production line equipment, and particularly to a blank station. Background Art

[0002] The products produced by the automated stamping line have diverse structures. With the increasing degree of automation, more and more outer panel parts, inner door panel parts, door frame parts, structural parts, etc. are gradually popularized for automated stamping production; moreover, with the continuous improvement of die process technology, the previous production mode of multi-stage dies such as five-stage for a single product has gradually been improved to four-stage or three-stage, and even two-stage production modes. The redundant blank processes in automated stamping line production require blank stations to replace the transfer process parts.

[0003] In the prior art, traditional dedicated blank stations have problems such as single use, high construction cost, high maintenance cost, large storage space requirements, inconvenient production switching and installation, etc.; at the same time, during the process of the robot end effector grasping and transferring, the dedicated blank station bracket is deformed during long-term use, resulting in problems such as material placement misalignment and dropping parts, which in turn lead to faults such as shutdown, product scrapping, and blocked waste pits by dropped parts; such problems not only restrict the production rhythm of the whole line, but also have great uncertainties, seriously restricting the production efficiency of the whole line and wasting energy. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a blank station, aiming to solve the technical problem of single use existing in the dedicated blank station in the prior art.

[0005] To achieve the above purpose, the present invention is implemented by the following technical solutions: a blank station, including a chassis, a placement platform provided on the chassis, and a driving component provided between the chassis and the placement platform.

A transmission gear set 40 is arranged between the transmission shaft 36 and the screw sleeve 38. Compared with the empty working station in the prior art, in the present invention, a driving component 30 is arranged between the placing platform 10 and the chassis 20 to adjust the height of the placing platform 10. By setting the coordinated feeding of the ball screw 37 and the screw sleeve 38, the precision control during height adjustment is ensured. At the same time, the empty working station in the present invention further includes a measuring component. The measuring component includes a scale 50 arranged on the chassis 20. One end of the scale 50 away from the chassis 20 is arranged close to the placing platform 10. It can be understood that when stamping products of the same model, the height data required for different products can be stored and retrieved to quickly adjust the height of the ball screw 37. However, after long-term use, the bracket is prone to deformation, resulting in the actual height of the placing platform 10 not reaching the preset height, affecting the processing of subsequent products. By setting the above-mentioned scale 50, after each use and when the ball screw 37 is reset, by observing whether there is a deviation between the placing platform 10 and the chassis 20, and specifically through the deviation value on the scale 50, the parameter feed amount is correspondingly adjusted or the product is disassembled and maintained to ensure the processing quality.

A plurality of pin holes 12 are opened on opposite sides of the plate body. Specifically, in some application scenarios of this embodiment, the above-mentioned positioning seats 11 are used to quickly align with the positioning pins of the storage table when placing the storage table. The above-mentioned storage table is used to place the workpieces required for stamping. The above-mentioned pin holes 12 are used for parts with a relatively large radian in the shaping structure. Through the above-mentioned pin holes 12, a special plug rod is used to support the workpiece. The plate body uses a 1mm thick skin plate.

[0030] In addition, in this embodiment, the above-mentioned empty working station further includes a plurality of hook brackets 70 arranged on the chassis 20. The above-mentioned hook brackets 70 are used to be tied with a steel wire rope during transportation to hoist it onto the equipment workbench.

[0031] Furthermore, in this embodiment, the placement platform 10 further includes a reinforcement structure disposed on one side of the plate body, the reinforcement structure includes a reinforcement tube 13 staggeredly disposed on one side of the plate body, and a fixing frame 14 for connecting with the ball screw 37 is fixed to one side of the reinforcement tube 13. Specifically, in this embodiment, the tube body includes a plurality of 40 square tubes and 40 angle steels staggeredly welded, and the fixing frame 14 is made of 80 angle steel, which is mainly used to withstand the bending moment generated by the eccentric load and lateral force.

[0032] Specifically, in this embodiment, the base frame 20 includes a bottom frame 21, and a support column 22 disposed on the bottom frame 21, a receiving groove is provided in the support column 22, a guide sleeve 61 is provided in the receiving groove, a guide shaft 62 is provided in the guide sleeve 61, and the guide shaft 62 is connected to the fixing frame 14.

However, after long-term use, the bracket is prone to deformation, resulting in the actual height of the placement platform 10 not reaching the preset height, which affects the processing of subsequent products. By providing the above-mentioned scale 50, after each use and when the ball screw 37 is reset, by observing whether there is a deviation between the placement platform 10 and the chassis 20, and specifically through the deviation value on the scale 50, the parameter feed amount is correspondingly adjusted or the product is disassembled and maintained to ensure the processing quality. By providing the above-mentioned reduction gear 32 and right-angle reduction gear 35, the rotation speed is reduced. While ensuring the stable movement of the ball screw 37, the torque of the driving component 30 is increased to improve the equipment load.
