Description

Technical Field

[0001] The present invention belongs to the technical field of sheet metal processing, and specifically relates to a vertical machine tool for sheet metal part processing. Background Art

[0002] Sheet metal processing is a process of making metal sheets into required-shaped and sized parts or finished products through processes such as cutting, bending, and stamping. This processing method is widely used in the manufacturing industry, including fields such as automobiles, electronics, and construction. Among them, stamping is a processing form that uses a punching press and a die to perform pressure processing on metal sheets to form various holes or complex shapes. Most of the existing sheet metal processing equipment is horizontal machine tools. However, for some metal parts, such as vertical equipment like building baffles and household appliance casings, horizontal sheet metal equipment requires a large amount of horizontal space for layout, and secondly, the feeding and discharging directions are completely opposite to the usage direction of the profiles. Therefore, it is necessary to flip them once again. This process will reduce the assembly efficiency of the parts and may also cause damage problems during the flipping process.

[0005] Preferably, the feeding assembly includes two columns, three first hydraulic rods are fixedly connected to the inner sides of the two columns, the telescopic ends of the three first hydraulic rods are movably hinged with arc-shaped blocks, the fronts of the three arc-shaped blocks are fixedly connected with square shells, and multiple first rollers are rotatably installed in the three square shells, and the multiple first rollers are all driven by electric motors.

[0006] Preferably, the guiding assembly includes two vertical plates. The tops of the two vertical plates are fixedly connected to two fixing blocks. Four long grooves are formed in the front surfaces of the two vertical plates. A second roller is rotatably installed in each of the four groups of long grooves.

[0007] Preferably, the two front connecting rods are fixedly connected to the front vertical plate, and the left side of the mold is fixedly connected to the other vertical plate.

[0008] Preferably, the stamping assembly includes two groups of support rods. The two groups of support rods are fixedly installed on the right sides of the two vertical plates. The two groups of support rods are arranged in an X shape. Connecting rods are fixedly connected to the inner sides of the two groups of support rods. A trapezoidal column is fixedly installed at the middle position of the two front support rods. Three second hydraulic rods are fixedly connected to the back of the trapezoidal column.

[0011] The beneficial effects of the present invention are as follows: 1. By installing a synchronous drive assembly in the present invention, two symmetrically installed first motors rotate clockwise. The rotational force is transmitted to the second runner through the drive belt by the two first runners. When the two first motors rotate, the bevel gear sets on their tops also play a synchronous role, ensuring that the symmetrically arranged second runners can rotate synchronously and at the same speed clockwise. The drive assembly drives multiple second rollers to rotate, clamping the sheet in this area, and moving the sheet to the right at a constant speed through the frictional force between the rollers and the sheet. When the sheet is vertically placed, it can also move to the right at a constant speed for sheet metal stamping, solving the problems that the traditional horizontal sheet metal equipment will reduce the assembly efficiency of parts and cause damage during the flipping process.

[0012] 2. The present invention installs a stamping component with an X-shaped bracket. The three second hydraulic rods increase the stroke. The U-shaped block drives the extrusion block to move from front to back. The extrusion block will perform a stamping on the sheet along the die. After stamping, the second hydraulic rods shorten the stroke. The sheet is driven by the second roller driven by the driving component and moves a certain distance again. The stroke of the second hydraulic rods is increased again to complete a stamping. This process is repeated. The X-shaped bracket can still maintain a high longitudinal supporting force after multiple stampings, reducing equipment deviation.

[0013] 3. The present invention installs a V-shaped discharging component. The eccentric motor rotates, driving the entire rectangular block to perform eccentric periodic motion. The rectangular block uses the circular shaft as one of the fulcrums, and the two opposite rubber pads perform periodic motion along an elliptical trajectory. When the two rubber pads approach each other, they clamp the sheet and provide a rightward moving force, thus assisting the processed sheet to be discharged. BRIEF DESCRIPTION OF THE DRAWINGS

A synchronizing rod 46 is fixedly connected between the two conical gear sets 45. Two fixing blocks 47 are movably sleeved on the outer edge of the synchronizing rod 46; When the two symmetrically installed first motors 41 rotate clockwise, the rotational force is transmitted to the second runners 44 through the transmission belts 43 by the two first runners 42. When the two first motors 41 rotate, the conical gear sets 45 at their tops also play a synchronizing role to ensure that the symmetrically arranged second runners 44 can rotate clockwise synchronously and at the same speed. The driving assembly 4 drives multiple second rollers 33 to rotate, and the sheet material can be clamped in this area, and the sheet material is uniformly moved to the right through the frictional force of contact between the rollers and the sheet material; Among them, the feeding assembly 2 includes two columns 21. Three first hydraulic rods 22 are fixedly connected to the inner sides of the two columns 21. The telescopic ends of the three groups of first hydraulic rods 22 are movably hinged with arc-shaped blocks 23. Square shells 24 are fixedly connected to the front sides of the three groups of arc-shaped blocks 23. Multiple first rollers 25 are rotatably installed in the three groups of square shells 24. The multiple first rollers 25 are all driven by electric motors; When the strokes of the multiple first hydraulic rods 22 increase, the arc-shaped blocks 23 hinged thereto will rotate a certain distance along the vertical plate 31, and the two square shells 24 will approach each other. The symmetrically arranged multiple first rollers 25 will clamp the sheet material in the vertical direction. At this time, the electric motors in the first rollers 25 are driven to drive the sheet material to feed from left to right; Among them, the guiding component 3 includes two vertical plates 31. The tops of the two vertical plates 31 are fixedly connected to two fixed blocks 47. Four long slots 32 are provided on the front surfaces of the two vertical plates 31.

A crawler 35 is movably sleeved on the outer edges of the two groups of rotating rods 34. The left outer edges of the two vertical plates 31 are movably hinged to three arc-shaped blocks 23. The top output shafts of the four groups of second rollers 33 penetrate through the vertical plates 31 and are fixedly connected to the bottoms of the second rotating wheels 44. The crawler 35 on the left side of the vertical plate 31 will first come into contact with the moving plate. The two crawlers 35 rotate along the rotating rods 34. The driving component 4 drives the rotation of multiple second rollers 33, which will firmly fix the plate in this area and move it to the right at a constant speed. Among them, the stamping component 5 includes two groups of support rods 51. The two groups of support rods 51 are fixedly installed on the right sides of the two vertical plates 31. The two groups of support rods 51 are arranged in an X shape. Connecting rods 52 are fixedly connected to the inner sides of the two groups of support rods 51.

The front ends of the back two connecting rods 52 are fixedly connected to a mold 57. The front two connecting rods 52 are fixedly connected to the front vertical plate (31). The left side of the mold 57 is fixedly connected to the other vertical plate 31. The three second hydraulic rods 54 increase the stroke. The extrusion block 56 is driven by the U-shaped block 55 to move from front to back. The extrusion block 56 will perform a stamping on the plate along the mold 57. After stamping, the second hydraulic rods 54 shorten the stroke. The plate is driven by the second rollers 33 driven by the driving component 4 to move a certain distance again. The stroke of the second hydraulic rods 54 is increased again to complete a stamping, and so on. Among them, the discharging component 6 includes two outer shells 61. The two outer shells 61 are both fixedly installed on the right sides of the two groups of support rods 51. The two outer shells 61 are arranged in a V shape.

The output shafts of the two eccentric motors 64 are fixedly connected to the inner walls of the outer shells 61. Rubber pads 65 are fixedly connected to the other ends of the two rectangular blocks 63. The two discharging components 6 in a V shape will perform a step-by-step clamping and discharging on the plate. The eccentric motor 64 rotates, driving the entire rectangular block 63 to perform an eccentric periodic motion. The rectangular block 63 uses the circular shaft 62 as one of the fulcrums. The two opposite rubber pads 65 perform a periodic motion along an elliptical trajectory. When the two rubber pads 65 approach each other, they clamp the plate and provide a moving force to the right.

[0018] Working principle: When using this device, first feed the sheet metal to be processed into the feeding assembly 2. The multiple first hydraulic rods 22 increase their strokes. The arc-shaped blocks 23 hinged to them will rotate a certain distance along the vertical plate 31. The two square shells 24 will approach each other. The multiple symmetric first rollers 25 will clamp the sheet in the vertical direction. At this time, driven by the electric motors in the first rollers 25, the sheet will be fed from left to right; When the sheet reaches the position of the guiding assembly 3, the crawlers 35 on the left side of the vertical plate 31 will first come into contact with the moving sheet. The two crawlers 35 rotate along the rotating rod 34. At this time, start the driving assembly 4. The two symmetrically installed first motors 41 rotate clockwise. The rotational force is transmitted to the second runner 44 through the transmission belt 43 by the two first runners 42. While the two first motors 41 are rotating, the bevel gear sets 45 on their tops will also play a synchronous role to ensure that the symmetric second runners 44 on the left and right can rotate synchronously and at the same speed clockwise; The driving assembly 4 drives the multiple second rollers 33 to rotate, clamping the sheet in this area. Through the frictional force between the rollers and the sheet, the sheet is moved to the right at a constant speed. When the right side of the sheet moves beyond the vertical plate 31 and reaches the stamping assembly 5, the three second hydraulic rods 54 increase their strokes. The U-shaped block 55 drives the extrusion block 56 to move from front to back. The extrusion block 56 will stamp the sheet along the die 57. After stamping, the second hydraulic rods 54 shorten their strokes. The sheet is driven by the second rollers 33 driven by the driving assembly 4 to move a certain distance again. Increase the stroke of the second hydraulic rods 54 again to complete one stamping, and so on; When the right side of the sheet is stamped and transported by the guiding assembly 3 away from the stamping assembly 5 to the discharging assembly 6, discharging is carried out. The two V-shaped discharging assemblies 6 will stepwise clamp and discharge the sheet. The eccentric motor 64 rotates, driving the entire rectangular block 63 to perform eccentric periodic motion. The rectangular block 63 takes the round shaft 62 as one of the fulcrums, and the two opposite rubber pads 65 perform periodic motion along an elliptical trajectory. When the two rubber pads 65 approach each other, they clamp the sheet and provide a rightward moving force. Thus, the working process ends.
