Description

Technical Field

[0001] This invention relates to the field of automotive steel processing technology, specifically to equipment and methods for processing automotive frame steel. Background Technology

[0002] In the automotive market, when users make daily car selections, the exterior design of the car is particularly important, which also involves the processing of the car frame. The car frame is generally made of steel, and the processing of the frame steel usually requires the use of a stamping device to stamp the steel. Existing stamping devices generally consist of a connecting plate, a stamping table, an electric telescopic rod, and a stamper.

[0003] Chinese patent CN220144453U discloses a processing device for automotive frame steel, including a connecting plate and a placement frame. The connecting plate has a fixing plate at its top, an electric telescopic rod at its bottom, a stamping device at its bottom, a base at the bottom of the connecting plate, a hollow metal block at its top, and a lifting device on the inner bottom wall of the hollow metal block. The placement frame has fixing devices on both sides. This automotive frame steel processing device allows the lifting device to be adjusted to a suitable height according to the operator's height. The steel is then placed in the placement frame and secured by the fixing devices. The electric telescopic rod moves the stamping device downwards to stamp the steel, resulting in better stamping effect and improved practicality of the stamping device.

[0004] In the process of developing this application, the following problems were discovered with the technology: the device lacks an automatic loading and unloading function for the steel awaiting stamping in the placement frame. Since the placement frame is directly below the stamping press, if the stamping equipment is not effectively and promptly shut off during processing, workers may accidentally drop the stamping press, directly or indirectly causing worker injury, if they manually or indirectly load the steel using contact tools (such as pliers). Therefore, to solve the aforementioned problems, it is necessary to invent a processing device and method for automotive frame steel. Summary of the Invention

[0057] The steel is placed on the transfer table. After the transfer table moves to the working position, the extrusion wheel of the clamping mechanism clamps the steel. Then, the position of the steel remains unchanged, and the stamping table moves to the working position.

[0058] In this embodiment, a transfer table and a stamping table are provided.

The other end of the fixed section and the other end of the telescopic section are respectively fixed to the stamping table and the rear plate.

[0064] Example 3

[0065] The structure and principle of Embodiment 3 are similar to those of Embodiments 1 and 2, except that: in order to prevent the steel from moving on the transfer table during the process of the drive assembly driving the transfer table to move in the chute; an electromagnetic plate 18 is fixedly provided at the edge of the transfer table near the front plate, and the electromagnetic plate extends straight into the interior of the transfer table; a corrugated pipe 19 with built-in power transmission line is also provided on the front plate, one end of the corrugated pipe is connected to the electromagnetic plate, and the other end of the corrugated pipe is fixed at the edge of the front plate.

[0066] In embodiments 1-3, a preferred structural form of the clamping mechanism is given, the clamping mechanism including...

[0067] Chassis 9, the chassis is fixedly located directly below the platform structure, and an installation cavity is provided inside the chassis;

[0068] The passive gear 20 is rotatably mounted in the mounting cavity of the chassis, and the bottom of the passive gear is rotatably connected to the chassis via a bearing; multiple arc-shaped grooves 25 are provided circumferentially on the passive gear.

[0069] The driving gear 21 and the second motor are connected to the driving gear, and the driving gear and the driven gear mesh.

[0070] The movable rod 23 has multiple guide sleeves 22 at the bottom of the chassis located on the driven gear. The position of the guide sleeves matches the position of the arc groove, and the movable rod is placed inside the guide sleeves.

[0071] The protruding rod 24 is vertically fixed at one end of the movable rod. The cross-sectional dimensions of the protruding rod match the dimensions of the arc groove, and it slides within the arc groove.

[0072] The connecting rod 26 is vertically fixed at the other end of the movable rod. The platform structure has inclined grooves 27 that match the number and position of the arc grooves. The length of the inclined groove is determined according to the size of the arc groove, and the width of the inclined groove matches the cross-section of the connecting rod. The connecting rod protrudes from the platform structure through the inclined groove and is slidably installed in the inclined groove. A pressing wheel facing the center of the platform structure is rotatably installed at the inner end of the protruding part of the connecting rod. The number of pressing wheels matches the number of arc grooves.

[0073] Preferably, two extrusion rollers are provided on each side of the slide groove of the platform structure, the four extrusion rollers are located at the four corners of the rectangle, and the center of the four extrusion rollers and the punch are located on the same vertical line.

[0074] In the above embodiment, in order to increase the height of the platform structure and facilitate the operation of the staff, a support platform 7 is fixedly provided between the chassis and the base plate.

[0075] In this embodiment, after the steel is transferred to the middle of the platform structure by the transfer table, the second motor is started to drive the drive gear to rotate clockwise. At this time, the drive gear will mesh with the driven gear and rotate counterclockwise, which will cause the arc-shaped groove on the driven gear to move counterclockwise circumferentially. At this time, since the guide sleeve guides and limits the movable rod, and the protrusion above the inner end of the movable rod slides in the arc-shaped groove, the arc-shaped groove moving counterclockwise circumferentially will squeeze and drive the protrusion to move towards the center of the driven gear. This will drive the connecting rods above the outer ends of the four movable rods to move closer to the center of the steel. At this time, the extrusion wheel on the inner side of the connecting rod will approach the steel and force the steel to be centered while clamping and fixing it, in preparation for stamping.

[0076] Example 4

[0077] The structure and principle of Embodiment 4 are similar to those of Embodiments 1 and 3, except that: a preferred form of lifting mechanism is given. Lifting mechanism is a relatively mature structure. This embodiment provides a preferred form, but other forms of lifting mechanism can also be used. The lifting mechanism includes lifting block 3, hydraulic rod 4, and connecting plate 5. Lifting grooves are provided on the side rails on both sides. The lifting block is slidably installed in the lifting groove. The top end of the hydraulic rod is fixedly installed on the top of the lifting groove. The extended end of the hydraulic rod is fixedly connected to the top of the lifting block 3. The two ends of the connecting plate are fixedly connected to the inner sides of the two lifting blocks. The stamping device is fixedly installed at the bottom of the connecting plate.

[0078] This invention also provides a method for processing automotive frame steel, using any of the automotive frame steel processing equipment described above, comprising the following steps:

[0079] Place the steel on the transfer table;

[0080] The drive component propels the transfer stage to the working position;

[0081] The clamping mechanism clamps and fixes the steel located at the center point, and the load-bearing component of the steel is switched from the transfer table to the clamping mechanism;

[0082] The drive component drives the transfer table away from the working point, and the reset component pushes the stamping table back to the working point.

[0083] The lifting assembly moves down, moving the stamper to the steel at the working point, and the stamper is started to complete the stamping work;

[0084] After the stamping process is completed, the above operation is repeated in reverse to transfer the stamped steel to the transfer table, where workers will remove it.

[0085] Specifically, firstly, when the automotive frame steel needs to be placed on the stamping table for stamping, the steel is first placed on a transfer table. At this point, the transfer table is not directly below the stamping press, thus ensuring safety. Next, the power is turned on to energize the electromagnetic plate, causing it to become magnetic, which then attracts and fixes the steel on the transfer table. Then, the first motor is started, driving the lead screw to rotate, causing the transfer table to move backward, pressing against the stamping table. When the transfer table reaches the middle of the table, the stamping table will then compress the rear reset assembly, causing it to retract and move to the rear of the table body.

[0086] Following the above, after the steel is transferred to the center of the platform, the second motor is started, driving the drive gear to rotate clockwise. At this time, the drive gear meshes with the driven gear and rotates counterclockwise, causing the arc-shaped groove on the driven gear to move counterclockwise circumferentially. Because the guide sleeve guides and limits the movable rod, and the protrusion above the inner end of the movable rod slides within the arc-shaped groove, the counterclockwise circumferential movement of the arc-shaped groove compresses and drives the protrusion towards the center of the driven gear, thereby causing the connecting rods above the outer ends of the four movable rods to move closer to the center of the steel. At this time, the pressing wheel on the inner side of the connecting rod approaches the steel and forcibly compresses and centers the steel, simultaneously clamping and fixing it in preparation for stamping.

[0087] After the steel is clamped and fixed by the extrusion rollers, the power supply to the electromagnetic plate is turned off, at which point the electromagnetic plate loses its magnetic attraction to the steel. Next, the first motor is started, driving the lead screw to rotate in the opposite direction, causing the slider to move the transfer table back to its original position. At this point, the stamping table loses the resistance of the transfer table and returns to the center of the platform under the rebound of the reset assembly. The clamped steel then falls above the stamping table. Finally, the hydraulic rod is activated, causing the lifting block to move the stamper at the bottom of the connecting plate above the steel, and the stamper is activated to perform the stamping process. After processing, following the same principle, the transfer table moves backward again to extrude the stamping table from the bottom of the steel, replacing the stamping table's position. The steel then falls back above the transfer table, and the clamping rollers are released, moving the steel back to its original position. Then, the power is turned on again to energize the electromagnetic plate, which then magnetically attracts the processed steel. The transfer table is then started to return to the front of the platform, allowing the processed steel to be removed from directly below the stamping press. In this design, the placement and removal of the steel are both done mechanically, and the operation avoids the position directly below the stamping press, thereby improving the safety of workers during processing.

[0088] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
