Detailed Implementation
[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] See Figures 1-4 This utility model provides a technical solution:
[0028] Example:
[0029] like Figures 1-4 As shown, an automatic combination line for forming, stamping and cutting of door frame bottom section includes a feeding rack 1, a shape forming device 2, a punching forming device 3 and a cutting device 4, wherein the feeding rack 1, the shape forming device 2, the punching forming device 3 and the cutting device 4 are arranged in sequence.
[0030] It also includes at least two lifting and protective material components 5, which are arranged sequentially along the feeding direction of the punching and forming device 3. The lifting and protective material components 5 are used to lift the profile 6 (after being formed by the profile forming device 2) before punching, so that there is a gap between the profile 6 and the lower die of the punching and forming device 3. During punching, the lifting and protective material components 5 move down synchronously with the profile 6 until the profile 6 contacts the lower die.
[0031] The lifting protective material assembly 5 includes an ear plate 7, a support member 8, a support horizontal shaft 9, and two support vertical shafts 10. The ear plate 7 includes a horizontal part and two vertical parts disposed on the horizontal part. The horizontal part and the two vertical parts form an inverted U-shaped structure. The two support vertical shafts 10 are respectively located on the outer sides of the two vertical parts.
[0032] The vertical part is provided with a waist-shaped groove 11 along the vertical direction. The two ends of the supporting horizontal shaft 9 pass through the waist-shaped grooves 11 of the two vertical parts respectively and are slidably sleeved on the supporting vertical shaft 10 (wherein, the end of the supporting horizontal shaft 9 is provided with a sliding hole coaxial with the supporting vertical shaft 10, and the supporting horizontal shaft 9 is slidably sleeved on the outside of the supporting vertical shaft 10 through the sliding hole).
[0033] The support member 8 is disposed on the support horizontal shaft 9, and the top surface of the support member 8 is higher than the top surface of the lower mold. An elastic reset member 12 is provided on the outside of the support vertical shaft 10. (The two ends of the elastic reset member 12 are located between the support horizontal shaft 9 and the horizontal part).
[0034] The support member 8 is a roller, and the support member 8 is rotatably mounted on the support horizontal shaft 9.
[0035] The elastic reset element 12 is a spring.
[0036] Wherein; 1, the shape forming device 2 is a roll forming machine, the feeding rack 1, and the punching forming device 3 is a punch press (the specific structure and principle are existing technologies and will not be described in detail here).
[0037] Working principle: Before forming, the profile 6 (a sheet material) is fed into the shape forming device 2 after being fed by the feeding rack 1. The shape forming device 2 shapes the sheet material into the shape outline of the profile 6.
[0038] After the profile 6 has been shaped, it enters the punching and forming device 3, which punches holes in the profile 6 to form the final profile 6 (in this embodiment, the punching is done twice, corresponding to two holes of the same or different shapes). After punching, it enters the cutting device 4 for cutting, and the target profile 6 is obtained after cutting.
[0039] Before the profile 6 enters the punching and forming device 3, it first passes through the lifting and guarding assembly 5, and the lifting and guarding assembly 5 lifts the profile 6 so that the bottom surface of the profile 6 is higher than the top surface of the lower mold. When the profile 6 passes through the lower mold or is above the upper mold, there is a gap between the profile 6 and the lower mold. Due to the existence of this gap, no friction is generated between the profile 6 and the lower mold.
[0040] During stamping, the upper die of the stamping forming device presses down on the profile 6, the profile 6 squeezes the support member 8, the support member 8 squeezes the spring and causes the support horizontal shaft 9 to slide downward in the oblong hole, thereby providing displacement space for the downward movement of the profile 6 and avoiding interference. At the same time, when the profile 6 moves on the support member 8, the support member 8 rolls, and there is rolling friction between the support member 8 and the profile 6, which has low frictional resistance and a small contact area between the support member 8 and the profile 6.
[0041] This utility model, by setting up a lifting and protective material assembly 5, can lift the profile 6 before it enters the stamping forming device, thereby preventing the profile 6 from contacting the lower mold and causing scratches when it enters the stamping forming device, which can effectively ensure the surface quality of the product; at the same time, it can also prevent the front end of the profile 6 from falling down and colliding with the lower mold.
[0042] Furthermore, such as Figure 3 and Figure 4As shown, the cutting device 4 includes a frame 13, a cutting mold 14, and a cutter 15. The cutter 15 is vertically arranged and driven by a telescopic component (the telescopic component is a cylinder or a hydraulic cylinder). The telescopic component is arranged on the frame 13. The cutting mold 14 is provided with a cavity that matches the cross-section of the profile 6. The cavity is arranged along the feeding direction of the punching and forming device 3 and extends through both sides of the cutting mold 14.
[0043] The top of the cutting mold 14 is provided with a cutting groove that is adapted to the cutter 15, and the cutting groove penetrates the cavity vertically.
[0044] The cutting die is also provided with a guide hole, which penetrates the cutting die along the feeding direction perpendicular to the punching forming device 3;
[0045] The guide hole has guide blocks 16 at both ends that can move along the axial direction of the guide hole (the guide blocks 16 are used to straighten the profile 6 and guide the profile 6, and the guide blocks 16 are adapted to the side shape of the profile 6). The guide blocks 16 are driven by cylinders.
[0046] After being stamped, the profile enters the cavity. During this process, the guide block straightens and guides the profile to prevent it from swaying and to allow it to pass through smoothly. After the profile passes through the cavity smoothly (for longer profiles, one end needs to pass through the cavity and reach the cutting length), the guide block exits the cavity, and the telescopic component drives the cutter to cut the profile through the cutting groove.
[0047] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
