Description

Hand hemming equipment with bottom part combined}

The present invention relates to a lower part integral hand hemming device, and more particularly to a lower part integral hand hemming device that is coupled to the front of the hydraulic cylinder in the lower part integral body, which can be hemmed by hand without a separate lower jig. will be.

In general, as described in the prior art in Korean Patent Publication No. 10-0782744, until a car manufacturer produces a car, a number of parts are sequentially assembled and completed. Particularly, assembling of the vehicle body is the first step in the assembly process, after producing product panels through various kinds of press devices, and then moving to the car body factory, each part of the product panels is assembled to form a white body (BIW) body. .

As described above, in order to mold automobile panels, pressing processes such as trimming, piercing, flanging, hemming, etc. Cutting, hole machining, bending, bending and other processing will be performed.

In addition, Patent No. 10-0782744 discloses a hemming apparatus, which is a hemming apparatus for hemming processing of a vehicle inner panel and an outer panel, wherein the outer panel is folded to the inside of the inner panel. A clamp for pressing downward; A clamp arm having one end fixed to an upper surface of the clamp; The front end of the bottom is hinged to the other end of the clamp arm, the front side end of the bottom hemming body is coupled to the locator for guiding the working direction of the clamp; A drive shaft penetrating the side of the hemming body and having a front portion hinged to the clamp arm to move forward and backward; It comprises a hemming bearing made by the clamping hemming operation, the drive shaft is the hydraulic pressure is driven by a hydraulic cylinder which is operated according to the hydraulic pressure controlled by the controller, the front of the clamp, The upper surface of the clamp leads to the lower surface of the clamp in a curved form, and is formed flat to the rear of the clamp at the position of the clamp lower surface of the first clamper to bend the panel to be worked, and the curved primary clamper ends It consists of a secondary clamper for pressing the panel bent flat by the primary clamper flat, the inner panel and the outer panel is seated on the upper surface of the hemming support is made by the clamping, the lower surface of the hemming support A guide groove having a shape is formed so that a protrusion formed on an upper surface of the locator is formed in the guide groove. As automobile panel hemming and wherein the mouth is slid and is made public.

However, in the prior art, due to the clearance of the lower guide groove in the hemming process, the clamp is not parallel to the upper surface of the lower jig, resulting in poor quality of the panel.

In addition, the elastic member was installed for the vertical movement of the clamp of the vehicle panel hemming device, the vehicle panel hemming device is a facility that must be transported by the operator's hand, so that the operator has difficulty in manual operation due to the weight increase.

In addition, both handles of the vehicle panel hemming device also have a problem in that the weight of the product is increased, and the overall weight of the vehicle panel hemming device is reduced and the high quality of the panel is required when the vehicle exterior panel hemming work is performed.

On the other hand, Patent No. 10-0610840 Heming device for hemming the panel having a flat section and the slope section at the same time, the main base mounted on the bottom of the work space; A first guide member vertically mounted on the main base; A first cam driver mounted on the upper mold to move up and down along the longitudinal direction of the first guide member; A first cam driver plate mounted and moved to the first cam driver; A first link plate mounted on one side of the base and rotatably mounted in a sliding movement of the first cam driver plate; A movement base mounted to enable the slide movement by the rotation of the first link plate; A plurality of second guide members vertically mounted to the moving base; A second cam driver mounted to the upper mold and lifted by being guided by the second guide member; A third cam driver mounted on the upper mold and lifted by being guided by the second guide member, the third cam driver being rotatably mounted in the inclined surface direction of the panel; A second / third cam driver plate mounted on the second / third cam driver and being elevated;

A second / third link plate rotatably mounted to the second / third cam driver plate in a sliding movement; A first hemming cam which performs a hemming operation of the planar section of the panel by the movement of the second link plate; And a second hemming cam for hemming the inclined section of the panel by the movement of the third link plate. The hemming apparatus of the panel having the inclined portion is disclosed.

In addition, Korean Patent Laid-Open Publication No. 10-2005-0116857 discloses a hemming apparatus for bending an edge of a lower panel to be combined with an upper panel, the lower die being placed on which the lower panel is placed; An upper die located at an upper portion of the lower die, the upper die having a fixing part moving in a lower direction to temporarily fix the upper panel to the lower panel; A pressing member which moves in a horizontal direction with respect to the lower panel and applies a pressing force to the edge of the lower panel to bend the edge of the lower panel so as to cover the edge of the upper panel and then retract in the horizontal direction; A punch member installed to be movable up and down with the upper die, and moving in a lower direction after the pressing member is evacuated to press the edge of the lower panel covering the upper panel to finish the hemming process; And a conveying means for moving the pressing member in a horizontal direction, wherein the pressing member has a pressing surface having a width that can include the front edge of the lower panel to be pressed, and the pressing surface has a horizontal direction in which the pressing surface is pressed. A hemming processing apparatus is disclosed which has an inclination with respect to.

However, since the handles are formed on both sides of the panel hemming device, the prior art increases the weight of the hemming device, and also has a disadvantage in that a separate lower mold jig is to be installed. .

Therefore, the present invention was conceived to solve the above problems, after placing the workpiece between the clamp end and the lower body integral body upper surface without a separate lower jig, the operator holding the handle with one hand and pressing the switch with the other hand Is to provide a lower body integral hand hemming device that can facilitate the operation by holding the cylinder body, can reduce the weight of the hand hemming device.
