[0024] A self-propelled sheet metal forming press, the overall structure diagram is as follows Figures 1 to 3As shown, it includes an embedded plate 7, a press 1, a lifting device 2, a moving device 4 and a moving bracket 6. The embedded plate is fixedly installed on the ground. The press includes a pillar 103 and a press body installed on the pillar. A plurality of moving roller devices 3 corresponding to the pillars are installed on the embedded plate. The lifting device is installed between the pillars and the corresponding moving roller devices to lift the press. The moving device is used to drive the press to move after being lifted. There are two moving brackets located on both sides of the press. The upper part of one end of the two moving brackets is hinged to the press, and the bottom of the other end is equipped with a moving bracket support wheel 601 that rolls on the embedded plate.

[0025] Multiple self-propelled sheet metal forming presses will be installed on the unwinding continuous stamping automatic production line. When the position of the self-propelled sheet metal forming press needs to be adjusted due to the production of parts of different lengths, the corresponding pillars can be lifted up by the jacking device, and the press can be pushed by the moving device and the moving bracket can be driven to move horizontally, thereby realizing the overall movement of the self-propelled sheet metal forming press to meet the production needs of parts of different lengths.

[0026] Here, four columns can be provided, which are located at the four corners of the press body.

[0027] The optimized press body includes an upper crossbeam 101, a lower crossbeam 102, a slider 104 and a main oil cylinder 105. The upper crossbeam and the lower crossbeam are respectively fixedly mounted on the pillars, the main oil cylinder is fixedly mounted on the upper crossbeam, and the slider is driven by the main oil cylinder to move up and down along the column.

[0028] Here, the number of master cylinders can be set as needed. In addition, slide rails can be set on the column, and the four corners of the slider are respectively installed on the slide rails, so that the master cylinder drives the slider to move more smoothly.

[0029] The optimized schematic diagram of the lifting device structure is as follows: Figure 4 As shown, it includes a lifting cylinder and a cylinder mouth flange 203. A clearance gap is provided on the side of the pillar. The cylinder body 201 of the lifting cylinder is fixedly installed at the clearance gap. The lower end of the piston 202 of the lifting cylinder is connected to the moving roller device. The cylinder mouth flange is fixedly installed at the cylinder mouth of the lower end of the cylinder body of the lifting cylinder.

[0030] When the position of the self-propelled sheet metal forming press needs to be adjusted due to the production of parts of different lengths, oil is injected into the upper chamber of the jacking cylinder, the piston of the jacking cylinder and the moving roller device remain stationary, the cylinder body of the jacking cylinder rises and the stroke of all the jacking cylinders is consistent, and it stops when the piston rod reaches the cylinder mouth flange. Since there is a clearance gap on the side of the support, the cylinder body of the jacking cylinder is fixedly installed at the clearance gap. When the cylinder body of the jacking cylinder rises, it will reach the clearance gap, thereby ensuring that the press is lifted as a whole and the press is kept stable as a whole. After the press is lifted as a whole, it is pushed by the moving device and drives the moving bracket to move in the horizontal direction, thereby realizing the overall movement of the self-propelled sheet metal forming press to meet the production needs of parts of different lengths, and the movement is relatively stable and labor-saving.

[0031] The optimized structure diagram of the mobile device and the detection device is as follows: Figure 5 As shown, the mobile device includes a rack 401, a mobile device gear shaft 402, a mobile device gear 403, a rotating rod 404 and an extension rod 405, the rack is fixedly mounted on the embedded plate, the mobile device gear shaft is rotatably mounted on the pillar, the mobile device gear is mounted on the inner side of the mobile device gear shaft and meshes with the rack, the rotating rod is mounted on the outer side of the mobile device gear shaft, and the extension rod is sleeved on the rotating rod.

[0032] When the press is lifted up as a whole, the operator rotates the extension rod, which drives the mobile device gear shaft and the mobile device gear to rotate. Since the mobile device gear is engaged with the rack, the rotation of the mobile device gear drives the mobile device gear shaft to move horizontally, thereby driving the entire press to move horizontally.

[0033] The rotating lever here can be designed in the form of a ratchet wrench, allowing forward or reverse rotation.

[0034] Furthermore, the movable roller device includes a movable roller guide plate 303, a movable roller bracket 302 and a movable roller 301. The movable roller guide plate is fixedly installed on the press, and the movable roller is installed on the movable roller bracket. The movable roller bracket is clamped in the movable roller guide plate and moves along the movable roller guide plate. Each movable roller bracket is guided by the guide plate, which can prevent the press from tilting during the jacking process.

[0035] Furthermore, a locating pin 10 is provided on the side of the press body, and the embedded plate is evenly provided with a plurality of locating pin holes 11. When the press is moved to the desired position, the locating pin is inserted into the corresponding locating pin hole to lock the press and prevent the press from slipping during the production process.

[0036] Furthermore, it also includes a mold 8, the mold structure diagram is as follows Figure 6As shown, a mold guide groove 801 is provided on the lower surface of the mold, and a mold guide roller 12 and a floating guide rail 13 are installed on the lower crossbeam, and the mold guide roller is located in the mold guide groove.

[0037] During the production process, the mold is supported by the mold guide rollers. When the mold needs to be replaced, the lifting cylinder of the floating guide rail lifts the rollers of the floating guide rail, so that the top of the mold guide groove is separated from the mold guide rollers and suspended on the rollers of the floating guide rail. The two sides of the mold guide groove are in contact with the mold guide rollers, which plays a good guiding role and facilitates the removal of the mold from the press, saving time and effort.

[0038] Furthermore, rollers 602 are provided on the upper surface of the movable bracket, and smooth strips 603 are provided on both inner and outer sides of the movable bracket along the extension direction, and the distance between the smooth strips on both sides is adjustable.

[0039] Specifically, a fixed bracket 606 can be fixedly installed on the movable bracket. The fixed bracket is equipped with multiple adjustment bolts 604. The ends of the adjustment bolts are fixed to the sides of the flow strips. The adjustment bolts are equipped with adjustment nuts 605 on the inside and outside of the fixed bracket. When the spacing between the two flow strips needs to be adjusted, the position of the adjustment bolts can be adjusted.

[0040] When the mold needs to be replaced, the mold will be moved out and moved along the smooth strips to the mobile bracket. The rollers on the upper surface of the mobile bracket will support the mold and reduce the friction between the mold and the mobile bracket. The smooth strips on both sides can provide guidance for the sides of the mold during movement. The spacing between the smooth strips on both sides is adjustable, which can adapt to molds of different widths and ensure the stability of the mold during movement. During the production process, the mobile bracket plays the role of supporting the plate.

[0041] Furthermore, it also includes a detection device 5, which includes a detection device gear shaft 501, a detection device gear 502 and a digital position indicator 503. The detection device gear shaft is rotatably mounted on the pillar, the detection device gear is mounted on the inner side of the detection device gear shaft and engages with the moving device gear, and the digital position indicator is mounted on the detection device gear shaft.

[0042] When the gear of the moving device rotates, it will drive the gear of the detection device and the gear shaft of the detection device to rotate together, thereby driving the inner ring of the connecting sleeve of the digital position indicator to rotate together, thereby feeding back the rotation angle to the data processing unit of the digital position indicator. The data processing unit of the digital position indicator establishes a mapping relationship between the moving distance of the press and the rotation angle of the gear shaft of the detection device based on the transmission ratio between the gear of the moving device and the rack, and the transmission ratio between the gear of the moving device and the gear of the detection device, and then intuitively displays the position information of the press on the digital display screen of the digital position indicator, thereby providing the operator with clear body position feedback.

[0043] Furthermore, a support plate 15 is fixedly installed at the bottom of the pillar, and a plurality of guide rollers 9 are arranged on both sides of the support plate. Figure 7 As shown, the guide roller guide plate 14 can be fixedly installed on the embedded plate, and the multiple guide rollers on each side of the support plate are installed on the corresponding guide roller guide plate, which is convenient for providing guidance when the press moves, and further prevents the center of the press from shifting during movement.

[0044] In summary, the self-propelled sheet metal forming press provided by the present invention can adjust the position of the press according to the requirements of the uncoiling continuous stamping automatic production line for parts of different lengths, thereby improving the production flexibility of the uncoiling continuous stamping automatic production line and making the adjustment smooth and labor-saving.
