Technical Field

The invention belongs to the technical field of sheet metal part machining, and relates to a device for cutting a sheet metal part.

Background

In the process of machining a white automobile body of an automobile, various sheet metal parts are often used, and redundant parts on the sheet metal parts need to be cut off after the sheet metal parts are machined. At present, the cutting method of the sheet metal part mainly comprises grinding sheet cutting, shearing machine cutting, stamping cutting, laser cutting and the like.

The grinding disc has high cutting noise and irregular cutting surface, and the completeness of the cutting surface cannot be guaranteed, so that the grinding disc can be generally used only in a common machining workshop and cannot be applied to a workshop with a higher standard; the shearing machine and the stamping cutting equipment have large volumes, cannot work on a sheet metal assembly with a local or special angle, and need high difficulty in non-standard design and installation, and cannot be used on the assembly after the sequence process is finished; although the laser cutting equipment has a good cutting effect, the equipment cost and the maintenance cost are high, the dropped waste materials cannot be conveyed, isolation treatment is needed in stations, and the occupied area is large.

Disclosure of Invention

The object of the present invention is to overcome the above-mentioned drawbacks of the prior art by providing a device for cutting sheet metal parts.

The purpose of the invention can be realized by the following technical scheme:

the utility model provides a device for sheet metal component cutting, the device include the base and set up riding wheel mechanism, cutting wheel mechanism and waste material fixture in the base side respectively, cutting wheel mechanism and riding wheel mechanism looks adaptation, the center pin of cutting wheel mechanism be higher than the center pin of riding wheel mechanism, and the bottom of cutting wheel mechanism be less than the top of riding wheel mechanism, the sheet metal component by the extrusion between cutting wheel mechanism and riding wheel mechanism and cut off.

Furthermore, the side of base still be equipped with the sheet metal component removal direction platform with sheet metal component looks adaptation. The sheet metal component removes the bending deformation of sheet metal component part after the guide table can avoid the cutting.

Furthermore, the riding wheel mechanism comprises a riding wheel fixing pin shaft inserted into the side face of the base along the horizontal direction, a riding wheel rolling bearing sleeved on the riding wheel fixing pin shaft and a riding wheel sleeved on the riding wheel rolling bearing. The riding wheels can support the sheet metal part from below and roll on the lower surface of the sheet metal part in the cutting process.

Furthermore, a supporting roller rolling bearing adjusting clamping sleeve is further sleeved on the supporting roller fixing pin shaft and is positioned between the supporting roller rolling bearing and the base. The riding wheel rolling bearing adjusting clamping sleeve can avoid the moving dislocation of the riding wheel rolling bearing in the cutting process, and the position of the riding wheel rolling bearing on the riding wheel fixed pin shaft is easy to adjust.

Furthermore, the cutting wheel mechanism comprises a cutting wheel fixing pin shaft inserted in the side face of the base along the horizontal direction, a cutting wheel rolling bearing sleeved on the cutting wheel fixing pin shaft and a cutting wheel sleeved on the cutting wheel rolling bearing. The cutting wheel is matched with the riding wheel to extrude and cut the sheet metal part.

Furthermore, a cutting wheel rolling bearing adjusting clamping sleeve is further sleeved on the cutting wheel fixing pin shaft and located between the cutting wheel rolling bearing and the base. The cutting wheel rolling bearing adjusting clamp sleeve can avoid the moving dislocation of the cutting wheel rolling bearing in the cutting process, and the position of the cutting wheel rolling bearing on the cutting wheel fixed pin shaft is easy to adjust.

Furthermore, the cutting wheel fixing pin shaft is higher than the riding wheel fixing pin shaft, and the bottom end of the cutting wheel is lower than the top end of the riding wheel.

Furthermore, a cutting gap is arranged between the cutting wheel and the riding wheel. By adjusting the cutting clearance, the thickness change of the sheet metal part which can be adapted to extrusion cutting is ensured, and the cutting surface is smooth.

Further, the cutting wheel overlap with the projection part of riding wheel on the base side, guarantee to pass through the device when the sheet metal component is, the cutting wheel can mutually support with the riding wheel and cut the sheet metal component.

Further, waste material fixture include set up the cylinder in the base side and with the clamping jaw of cylinder transmission connection. The cylinder drives the clamping jaw to move, and the cut waste is clamped. The waste material fixture also can adopt an electromagnetic clamping mode to clamp sheet metal part waste materials with different sizes.

When in actual application, can design corresponding base and waste material fixture according to the concrete shape of sheet metal component, guarantee going on smoothly of cutting process. The diameters of the riding wheel and the cutting wheel can be adjusted according to the thickness and the space size of the sheet metal part.

When the device is applied, the device is arranged on a robot or other tools and moves towards the direction of a sheet metal part along with the robot or other tools; the bottom of the sheet metal part is firstly contacted with the riding wheel, and then the cutting wheel is matched with the riding wheel to extrude and cut the sheet metal part along with the continuous movement of the device; when the sheet metal part is completely cut off, the waste material clamping mechanism grabs the waste material of the sheet metal part; the device continues to move to a scrap box to discard the sheet metal piece scrap.

Compared with the prior art, the invention has the following characteristics:

1) the application range is wide: according to the specific shape of the sheet metal part, a corresponding base and a waste clamping mechanism are designed, so that the device can be used for cutting sheet metal parts in various complex positions and peculiar shapes;
