Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to a connecting rod type edge wrapping unit. Background Art

[0002] Hot pressing hemming is a common processing technology for automobile parts. The edges of automobile parts are hemmed by hot pressing to increase their wear resistance, aesthetics and service life. Automobile parts are usually made of various materials, such as plastic, rubber, leather, etc. Their edges need to be processed during the production process to prevent burrs, fluffing or cracks in the corners of the plastic. For hot pressing hemming molds, the hemming unit is the core structure of this mold. Due to the structural limitations of the product, some places cannot be automatically hemmed and need to be manually processed later. For example, in narrow places where the product is relatively narrow, there is not enough space to arrange the hemming unit, so the automatic hemming of this part has to be abandoned, and it has to be manually hemmed, which greatly increases the cost, and the consistency of the product cannot be guaranteed, affecting the efficiency and effect of the product hemming.

[0026] Reference Figure 1-Figure 2 The utility model provides a technical solution: a connecting rod type hemming unit, including a mounting base 1 and a connecting rod hemming mechanism, a mounting seat 2 is installed on the top of the mounting base 1, and when the mounting base 1 cooperates with the mounting base 2 to work, the mounting base 2 can move toward the external workpiece to perform contact hemming work, and when performing mobile hemming, the workpiece surface can be hemmed at multiple angles, thereby improving the efficiency of workpiece hemming and avoiding the situation where it is difficult to hem at multiple angles during the workpiece processing process, thereby improving the efficiency and effect of workpiece hemming.

[0027] Reference Figure 1-Figure 2In a preferred embodiment, the connecting rod hemming mechanism includes a left connecting rod 3, which is installed on the left side of the front side of the mounting seat 2 through a hinge support, and the outer side of the left connecting rod 3 is installed with a left hemming block 4 through a hinge support, and the right connecting rod 5 is installed on the right side of the front side of the mounting seat 2 through a hinge support, and the outer side of the right connecting rod 5 is installed with a right hemming block 6 through a hinge support, and the main hemming block 7 is installed on the front side of the mounting seat 2. The mounting seat 2 pushes the left hemming block 4, the right hemming block 6 and the main hemming block 7 through the left connecting rod 3 and the right connecting rod 5 to move toward the workpiece direction. The left guide rail 8 is installed on the left side of the top of the mounting base 1, and the top of the left guide rail 8 is slidably connected with the bottom of the left hemming block 4. When the left connecting rod 3 cooperates with the left hemming block 4 to work, the left hemming block 4 and the mounting base 1 can be actively guided to avoid position deviation of the left hemming block 4 when working, resulting in irrational hemming effect, thereby improving the working stability of the left hemming block 4.

[0028] Reference Figure 1-Figure 2 In a preferred embodiment, a right guide rail 9 is installed on the right side of the top of the mounting base 1, and the top of the right guide rail 9 is slidably connected to the bottom of the right edging block 6. When the mounting base 2 pushes the right edging block 6 to work through the right connecting rod 5, the right edging block 6 and the mounting base 2 can be guided and connected during the movement to avoid the position shaking of the right edging block 6 when it moves, thereby improving the movement stability of the right edging block 6. A main guide rail 10 is installed on the front side of the top of the mounting base 1, and the top of the main guide rail 10 is slidably connected to the bottom of the main edging block 7. When the mounting base 2 pushes the main edging block 7 bracket, the movement trajectory of the main edging block 7 at the top of the mounting base 1 after being pushed by the mounting base 2 can be guided and restricted to avoid the misalignment of the main edging block 7 when it moves, thereby improving the working stability of the main edging block 7.

[0029] Reference Figure 1-Figure 2In a preferred embodiment, a cylinder 11 is installed on the rear side of the top of the mounting base 1, and a floating connector 12 is installed on the output end of the cylinder 11. The front side of the floating connector 12 is connected to the rear side of the mounting base 2. When the mounting base 2 cooperates with the left edge block 4, the right edge block 6 and the main edge block 7, the mounting base 2 can be provided with moving power. At the same time, the floating joint ensures the connection effect between the cylinder 11 and the mounting base 2, avoiding the situation that the mounting base 2 is difficult to effectively cooperate with the left edge block 4, the right edge block 6 and the main edge block 7 to complete the work when the mounting base 2 is working, thereby providing In order to improve the pushing effect of the mounting seat 2, a collision block 13 located on the left side of the mounting seat 2 is arranged on the top of the mounting base 1, and the right side of the collision block 13 is fixedly connected to the left side of the mounting seat 2. When the cylinder 11 cooperates with the mounting seat 2 through the floating connector 12, the front limit block 15 and the rear limit block 14 can be used to limit the front and rear movement distance of the mounting seat 2 in a contact manner, so as to ensure that the mounting seat 2 is moved and fixed during operation to perform moving work, and avoid excessive movement of the mounting seat 2 during operation, thereby improving the convenience of movement restriction of the mounting seat 2.

[0030] Reference Figure 1-Figure 2 In a preferred embodiment, a rear limit block 14 is installed on the rear side of the left side of the top of the mounting base 1, and the rear limit block 14 is located on the rear side of the impact block 13. When the impact block 13 cooperates with the mounting seat 2 to work, the rearward movement of the impact block 13 can be blocked and limited, thereby avoiding the situation where it is difficult to limit the rearward movement distance of the mounting seat 2 when the impact block 13 is working, thereby improving the rearward movement limiting effect of the impact block 13 on the mounting seat 2. A front limit block 15 is installed on the left side of the top of the mounting base 1, and the front limit block 15 is located on the front side of the impact block 13. The front limit block 15 contacts the impact block 13, and can provide the impact block 13 with a medium for limiting the forward movement of the mounting seat 2 when the impact block 13 cooperates with the mounting seat 2 to work, thereby avoiding the situation where it is difficult to effectively limit the forward movement of the mounting seat 2 when the impact block 13 is working, thereby improving the forward movement limiting effect of the impact block 13 on the mounting seat 2.

[0031] Specifically, the working process or working principle of this kind of connecting rod type hemming unit is as follows: when in use, first determine the moving stroke of the mounting seat 2 according to the actual hemming requirements of the workpiece to be processed, and then install the front limit block 15 and the rear limit block 14 on the top of the left side of the mounting base 1 according to the actual stroke of the mounting seat 2, and make the impact block 13 located on the inner side of the front limit block 15 and the rear limit block 14. It should be noted that the distance between the front limit block 15 and the rear limit block 14 minus the length of the impact block 13 is the moving stroke distance of the mounting seat 2. Subsequently, connect the cylinder 11 to an external controllable air source so that the cylinder 11 can provide a controllable translational driving force to the mounting seat 2 through a floating joint. Then, determine the hemming position of the workpiece so that the workpiece is in a stable state during the hemming process. This operation can be performed according to In actual situation, it is completed with the help of a clamp or a processing base, and then the cylinder 11 is used in conjunction with the floating joint to apply a forward thrust to the mounting base 2. The mounting base 2 is subjected to force through the left connecting rod 3 and the right connecting rod 5 to push the left edging block 4, the right edging block 6 and the front side of the main edging block 7 to move and contact the workpiece. Since the positions of the left edging block 4, the right edging block 6 and the main edging block 7 are different, when they come into contact with the workpiece, the surface of the workpiece can be contacted and hemmed at multiple angles to improve the hemming efficiency of the workpiece. During this process, the left guide rail 8 and the right guide rail 9 cooperate with the main guide rail 10 to guide and limit the moving trajectory of the left edging block 4, the right edging block 6 and the main edging block 7 during the moving process, to ensure that the left edging block 4, the right edging block 6 and the main edging block 7 move on a relatively fixed trajectory when moving for hemming work.

[0032] It should be noted that the cylinder 11 and the floating joint are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
