Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of automotive parts processing technology, and more specifically, to a standby open-type fixed table press for stamping automotive rear covers. Background Technology
[0002] Traditional open-type fixed-table presses have revealed many problems when faced with the task of stamping and manufacturing car rear covers. In the material placement and positioning stage, most presses rely on manual placement of blanks, which is not only inefficient but also difficult to guarantee positioning accuracy. Deviations in the placement of blanks will cause deviations in the dimensional accuracy of the stamped car rear covers, increasing the defect rate and raising production costs.
[0003] From the perspective of material feeding operation, the material placement area layout of conventional presses is fixed and lacks the function of flexible adjustment. When it is necessary to change different specifications of car rear cover blanks in batches, or to make fine adjustments to the position of the blanks during the stamping process, operators often need to spend a lot of time rearranging the materials, which seriously affects the continuity of production and overall efficiency, and can also cause personnel injuries. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a standby open fixed table press for stamping automobile rear covers. This solves the problem that, from the perspective of material feeding operation, conventional presses have a fixed layout of material placement area and lack flexible adjustment function. When it is necessary to change different specifications of automobile rear cover blanks in batches, or to make fine adjustments to the position of the blanks during the stamping process, operators often need to spend a lot of time rearranging the materials, which seriously affects the continuity of production and overall efficiency, and can also cause technical problems such as accidental injury to personnel.

A rotating disk is disposed on the side wall of the processing table, a swing frame is disposed on the side wall of the rotating disk, a telescopic frame is disposed on the side wall of the swing frame, a movable frame is fitted on the telescopic frame, and a material placement tray is disposed at the bottom of the movable frame. The material placement tray is attached to the force-bearing platform.
[0010] As a further technical solution, a positioning groove is provided on the force-bearing platform, and a positioning strip is provided at the bottom of the material placement tray, with the positioning strip embedded inside the positioning groove.

A connecting plate is fixedly mounted on the pressing shaft. A sliding column is disposed between the processing table and the pressing platform, and the connecting plate is mounted on the sliding column.
[0012] As a further technical solution, a pressing head is provided on the lower end face of the connecting plate, and the pressing head corresponds to the position of the force-bearing platform.
[0013] As a further technical solution, the end of the swing frame is provided with a mounting plate, and the telescopic frame is disposed on the inner side wall of the mounting plate.
[0014] As a further technical solution, the side wall of the movable frame is provided with a linkage frame, which is fixedly connected to the material placement tray, and the material placement tray is provided with a placement layer.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:
[0018] In this disclosure, the rotary feeding assembly's rotating disk, swing frame, and telescopic frame work together to enable flexible switching of the material placement tray at different positions around the processing table. When it is necessary to change to different specifications of automotive rear cover blanks, or to make fine adjustments to the blank position during the stamping process, the operator does not need to rearrange the entire material placement area as with traditional presses. The operation can be completed quickly simply by controlling the movement of each component.

[0030] like Figures 1-3 As shown, it illustrates a spare open-type fixed-table press for stamping automobile rear covers according to this disclosure, comprising:
[0031] Processing table 1, with a pressure table 2 installed on it;
[0032] Rotary feeding assembly 3 is disposed on the upper surface of processing table 1;
[0033] Pressing processing component 4 is mounted on the pressing table 2;
[0034] The rotary feeding assembly 3 includes a force-bearing platform 3-1, which is located on the upper surface of the processing table 1. A rotating disk 3-2 is provided on the side wall of the processing table 1. A swing frame 3-3 is provided on the side wall of the rotating disk 3-2. A telescopic frame 3-4 is provided on the side wall of the swing frame 3-3. A movable frame 3-5 is fitted on the telescopic frame 3-4. A material placement tray 3-6 is provided at the bottom of the movable frame 3-5. The material placement tray 3-6 is attached to the force-bearing platform 3-1.
[0035] The pressing processing component 4 includes a pressing shaft 4-1, which is mounted on the pressing table 2. A connecting plate 4-2 is fixedly mounted on the pressing shaft 4-1. A sliding column 4-3 is provided between the processing table 1 and the pressing table 2, and the connecting plate 4-2 is mounted on the sliding column 4-3.
[0036] In some examples, the processing table 1, as the basic support structure of the entire press, needs to have sufficient strength and stability to bear the forces of the subsequently installed components and the stamping process. It can be made of high-strength steel, and precision machining ensures its surface flatness and dimensional accuracy of each installation part. The lower press table 2 is installed on the processing table 1, and the two can be fixed together by bolts or welding to ensure a strong connection. The lower press table 2 is used to install the lower pressing processing component 4. Its material and processing technology are similar to those of the processing table 1, and the corresponding mounting holes and positioning structures need to be precisely drilled according to the installation requirements of the lower pressing processing component 4. The force-bearing table 3-1 is installed on the upper surface of the processing table 1. During installation, the upper surface of the force-bearing table 3-1 must be kept submerged in water. The rotating disk 3-2 is mounted on the side wall of the processing table 1 and is tightly and firmly connected to the processing table 1. Sealant or anti-loosening gaskets can be applied to the contact surface between the force-bearing platform 3-1 and the processing table 1 to prevent loosening during equipment operation. The rotating disk 3-2 is mounted on the side wall of the processing table 1 and can be rotatably connected to the processing table 1 through bearings to reduce friction during rotation. The swing frame 3-3 is mounted on the side wall of the rotating disk 3-2. The two can be connected by welding or bolts. The connection part must be strong enough to withstand the tension and torque generated by the swing frame 3-3 during movement. The length and angle of the swing frame 3-3 need to be designed according to the overall layout of the equipment and the movement trajectory of the material placement tray 3-6 to ensure that the swing frame 3-3 can drive the material placement tray 3-6 to move accurately to the required position.
[0037] The lower pressure shaft 4-1 is mounted on the lower pressure table 2. The lower pressure shaft 4-1 and the lower pressure table 2 are connected by bearings, allowing the lower pressure shaft 4-1 to rotate freely. The connecting disc 4-2 is fixedly mounted on the lower pressure shaft 4-1. The fixing method can be a key connection or an interference fit, ensuring that the connecting disc 4-2 can rotate synchronously with the lower pressure shaft 4-1. The size and structure of the connecting disc 4-2 must be designed according to the stamping requirements of the equipment to ensure that it can stably transmit power during rotation, driving the lower pressure head 4-4 to perform the stamping operation. This is located on the upper end of the processing table 1. Sliding columns 4-3 are installed at the four corners of the machine. The sliding columns 4-3 are connected to the processing table 1 by a bearing assembly. The bearing selection should be determined according to the load-bearing capacity and operating speed of the equipment to ensure that the sliding columns 4-3 can rotate flexibly. The top of the sliding columns 4-3 is also connected to the lower press table 2 by a bearing assembly, so that the lower press table 2 can slide up and down on the sliding columns 4-3. The height and diameter of the sliding columns 4-3 need to be designed according to the overall structure of the equipment and the stamping stroke to ensure the stability and accuracy of the lower press table 2 during the sliding process.
[0038] like Figures 1-3 As shown in the figure, this embodiment proposes that the force-bearing platform 3-1 is provided with a positioning groove 3-7, and the bottom of the material placement tray 3-6 is provided with a positioning strip 3-8, which is embedded in the interior of the positioning groove 3-7.
[0039] In some examples, the positioning groove 3-7 on the force-bearing platform 3-1 needs to be precisely machined according to the size and shape of the positioning strip 3-8 at the bottom of the material placement tray 3-6. The depth and width of the positioning groove 3-7 must ensure that the positioning strip 3-8 can be smoothly embedded, and after embedding, there is a certain degree of fit accuracy, so as to achieve accurate positioning of the material placement tray 3-6, and allow for fine adjustment within a certain range.
[0040] For example, such as Figure 1 As shown, a pressing head 4-4 is provided on the lower end face of the connecting plate 4-2, and the pressing head 4-4 corresponds to the position of the force-bearing platform 3-1.
[0041] In some examples, a lower pressure head 4-4 is installed on the lower end face of the connecting plate 4-2 at the lower end of the lower pressure shaft 4-1. The lower pressure head 4-4 and the connecting plate 4-2 can be connected by bolts or welding. The connection part must ensure strength and be able to withstand the huge pressure during stamping. The shape and size of the lower pressure head 4-4 should be designed according to the stamping die of the car rear cover to ensure that the lower pressure head 4-4 can act accurately on the die to realize the stamping processing of the car rear cover blank. After installation, the position of the lower pressure head 4-4 needs to be adjusted to ensure that the lower pressure head 4-4 corresponds to the position of the material placement plate 3-6 on the force table 3-1 and can press down vertically during the stamping process to avoid the phenomenon of bias pressure.
[0042] For example, such as Figure 1 As shown, the end of the swing frame 3-3 is provided with a mounting plate 5, and the telescopic frame 3-4 is provided on the inner side wall of the mounting plate 5.
[0043] In some examples, a telescopic frame 3-4 is installed on the inner wall of the mounting plate 5 at the end of the swing frame 3-3. The telescopic frame 3-4 can be in the form of an electric telescopic rod or a hydraulic telescopic rod. If an electric telescopic rod is used, a power supply and control system need to be connected to ensure that the telescopic rod can extend and retract accurately according to the command. The movable frame 3-5 is fitted on the telescopic frame 3-4, and the movable frame 3-5 and the telescopic frame 3-4 can be in a sliding fit.
[0044] For example, such as Figure 2 As shown, a linkage frame 6 is provided on the side wall of the movable frame 3-5. The linkage frame 6 is fixedly connected to the material placement tray 3-6, and a placement layer 7 is provided on the material placement tray 3-6.
[0045] In some examples, a linkage frame 6 is installed on the side wall of the movable frame 3-5. The linkage frame 6 is fixedly connected to the material placement tray 3-6. The fixing method can be welding or bolt connection. The positioning strip 3-8 at the bottom of the material placement tray 3-6 should be precisely machined to ensure accurate matching with the positioning groove 3-7 on the force-bearing table 3-1. The placement layer 7 on the material placement tray 3-6 can be made of rubber or other materials with certain cushioning and anti-slip properties to protect the car rear cover blank placed on it and prevent the blank from shifting during processing.
[0046] For example, such as Figure 1 As shown, the sliding column 4-3 is located at the four corners of the upper end face of the processing table 1. The structure of the processing table 1 and the lower pressure table 2 are matched. The sliding column 4-3 and the processing table 1 are connected by a bearing. The top of the sliding column 4-3 and the lower pressure table 2 are connected by a bearing.
[0047] In use, the car rear cover blank is placed on the placement layer 7 of the material placement tray 3-6. The cushioning and anti-slip material of the placement layer 7 ensures that the blank is placed stably. Then, by controlling the extension of the telescopic frame 3-4, the linkage frame 6 drives the movable frame 3-5 to slide along the telescopic frame 3-4, so that the material placement tray 3-6 is away from the end of the swing frame 3-3. Next, the swing frame 3-3 swings around the connection point with the rotating disk 3-2, moving the material placement tray 3-6 above the force-bearing platform 3-1. Then, the telescopic frame 3-4 is controlled to retract, so that the positioning strip 3-8 at the bottom of the material placement tray 3-6 is embedded in the positioning groove 3-7 on the force-bearing platform 3-1, completing the precise initial positioning of the blank.
[0048] When it is necessary to change the blanks on the material placement tray 3-6 or adjust their position, the rotating tray 3-2 rotates around the bearing connected to the processing table 1 under the drive of the drive device (such as a motor via a transmission belt or gear set). When the rotating tray 3-2 rotates, it drives the swing frame 3-3, the telescopic frame 3-4, the movable frame 3-5 and the material placement tray 3-6 to rotate together, so as to realize the switching of the material placement tray 3-6 in different positions around the processing table 1, which is convenient for operators to perform loading and unloading operations, and can also rationally plan the working space around the equipment.
[0049] The lower pressure shaft 4-1 begins to rotate under the drive of a power source (such as a motor via a coupling or other transmission components). Since the connecting plate 4-2 is fixedly mounted on the lower pressure shaft 4-1 via a key connection or interference fit, the connecting plate 4-2 rotates synchronously with the lower pressure shaft 4-1. When the connecting plate 4-2 rotates, the lower pressure head 4-4 on its lower end face also rotates. Simultaneously, the lower pressure table 2 slides up and down on the sliding column 4-3. The bearing connection between the sliding column 4-3 and the processing table 1 and the lower pressure table 2 ensures the flexibility and stability of the sliding of the lower pressure table 2. When material is placed on the tray 3-6... After the blank is positioned, the lower press table 2 slides down along the sliding column 4-3, causing the lower press shaft 4-1 and the connecting plate 4-2 to descend together. The lower press head 4-4 gradually approaches the blank. When the lower press head 4-4 contacts the stamping die above the blank, the continuous rotation of the lower press shaft 4-1 causes the connecting plate 4-2 to drive the lower press head 4-4 to apply pressure to the die, thereby stamping the blank. During the stamping process, the sliding column 4-3 provides guidance and support for the lower press table 2, ensuring that the lower press head 4-4 can stamp the blank vertically and stably, thus ensuring stamping accuracy and product quality.
[0050] After stamping is completed, the lower pressing shaft 4-1 stops rotating and starts to rotate in the opposite direction under the reverse drive of the power source, driving the connecting plate 4-2 and the lower pressing head 4-4 to move upward. At the same time, the lower pressing table 2 slides upward and resets along the sliding column 4-3. At this time, the material placement plate 3-6 that has been stamped can be removed by controlling the rotating feeding component 3, and a new material placement plate 3-6 containing blanks can be placed on it. The above process is repeated to realize the continuous stamping preparation of the car rear cover.
[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
