Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to an automatic feeding mechanism for punching machine profiles. Background Art

[0002] During the process of upgrading and renovating production equipment, manufacturing and processing enterprises often encounter large-scale mechanical processing equipment, such as punching machines, whose service life is far from reaching its service life. These old-fashioned punching machines have a relatively simple structural design and can only be loaded, stamped, and unloaded manually, and cannot be integrated into automated production lines.

[0003] In particular, in the process of stamping and forming the coiled material profile, if workers manually withdraw the material, it is impossible to ensure that the progress of each pushing is the same, resulting in more waste and increasing production costs. For example, the Chinese patent with the announcement number CN210877005U discloses a slicing device with a clamping function, including a slicing device with a clamping function, including a winding device and a knife holder, on which a knife seat is installed; also including a limit seat, a lower pressure piece is arranged on the knife seat, and the limit seat is provided with an elastic button directly below the lower pressure piece, and one end of the elastic button passes through the limit seat; the limit seat is provided with a vertical clamping part in the conveying direction of the copper strip, and the vertical clamping part includes a first clamping block and a first clamping seat arranged up and down, the first clamping seat is arranged on the fixed seat, and an upper elastic member is arranged between the first clamping block and the first clamping seat; an upper pressing rod is arranged on the side of the first clamping block facing the first clamping seat, the upper pressing rod passes through the limit seat, and a pressing plate is fixed to one end of the upper pressing rod located below the limit seat, and the pressing plate extends to the bottom of the elastic button.

[0004] The above structure cannot effectively meet the feeding requirements of coil profile stamping, and cannot quickly adjust the interval of each feeding according to the size of the stamped parts, so it is difficult to meet the use requirements. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide an automatic feeding mechanism for punch press profiles, which can automatically feed the coils in a quantitative manner, thereby reducing labor costs, improving the accuracy of the quantitative feeding of the coils, and reducing the waste of the coils, thereby achieving the purpose of reducing production costs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic feeding mechanism for a punching machine profile, comprising a mounting frame, on which an upper die and a lower die are mounted. When in use, the mounting frame is mounted on a punching machine, and the upper die is connected to a hydraulic device of the punching machine, and the upper die can be driven to move toward the lower die by the hydraulic device.

[0007] It also includes a feeding mechanism, which includes two groups of two feeding rollers respectively installed on both sides of the lower mold, and the feeding rollers can move the profile;

[0008] It also includes a driving mechanism, the driving mechanism includes a driving shaft mounted on a mounting frame, and a driving wheel is mounted on the driving shaft, and one of the feeding rollers of the two groups of feeding rollers is connected by a belt;

[0009] It also includes an adjustment mechanism, which can adjust the feed roller connected to the drive wheel through the belt to rotate a preset number of times each time the upper mold and the lower mold are in contact;

[0010] The two feeding rollers in the same group are meshed with gears, and when the upper mold moves away from the lower mold, the driving shaft can be driven to rotate, and when the upper mold moves toward the lower mold, the driving shaft will not be driven to rotate.

[0011] As a preferred technical solution of the utility model, the driving mechanism includes a one-way bearing, the outer ring of the one-way bearing is fixedly connected to the driving wheel, and the inner ring of the one-way bearing is fixedly connected to the driving shaft.

[0012] As a preferred technical solution of the utility model, the driving mechanism also includes a driving gear fixed on the driving shaft, and a rack meshing with the driving gear is installed on the upper mold, and the one-way bearing can only rotate when the rack moves downward.

[0013] The one-way bearing can only rotate in one direction. Therefore, when the upper mold approaches the lower mold, the bearing will rotate. However, since the driving wheel is connected to the feed roller through a belt, the driving wheel will not rotate. When the upper mold moves away from the lower mold, the bearing is locked, so it is fixed to the driving wheel, thereby driving the driving wheel to rotate and realize the feeding of the coil.

[0014] As a preferred technical solution of the utility model, the surface of the feeding roller is provided with anti-skid patterns.

[0015] The anti-slip texture can increase the friction between it and the coil, thereby improving the pushing effect on the coil and avoiding sliding during the feeding process.

[0016] As a preferred technical solution of the utility model, the adjusting mechanism includes a hollow shaft installed on a feed roller connected to a driving shaft through a belt, the hollow shaft has a plurality of sliding holes distributed along its axis, a rotating rod rotatably installed on the driving shaft is coaxially installed inside the hollow shaft, and the rotating rod is provided with two sections of threads with opposite rotation directions, and the two sections of threads are matched with moving blocks, the adjusting mechanism also includes a plurality of adjusting plates with the same number and sliding holes, and two connecting rods are rotatably installed on the adjusting plates, the two connecting rods are respectively rotatably connected to the two moving blocks, and the driving shaft and the plurality of adjusting plates are connected by belts.

[0017] By setting a rotating rod, a moving block and a connecting rod, when it is necessary to adjust the distance that the coil moves each time, the rotating rod is rotated to adjust the spacing between the two moving blocks, thereby achieving a corresponding adjustment of the axial spacing between multiple adjustment plates and the rotating rod, thereby changing the diameter formed by the multiple adjustment plates, and utilizing the elasticity of the belt to achieve different numbers of adjustments of the feed roller under the premise of rotating the same number of driving wheels, so that rapid adjustments can be made according to different stamping parts.

[0018] As a preferred technical solution of the utility model, the adjustment plates are all arc-shaped with their openings facing the driving shaft.

[0019] The arc opening can fit the belt more closely, increase the contact area with the belt, further improve the friction, and avoid the belt slipping during feeding.

[0020] As a preferred technical solution of the utility model, baffles are installed at both ends of the adjustment plate.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The relative movement between the molds is used to achieve quantitative feeding of the coil material, which reduces the manufacturing cost and improves the accuracy of feeding the coil material, avoiding the large gap changes caused by manual feeding and the large amount of waste generated, thereby reducing the production cost.

[0023] Rapid adjustment according to different stamping parts further improves the use effect of the device and enhances the versatility of the device, while reducing the cost and time required to replace the feeding mechanism and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

When in use, the mounting frame 3 is mounted on a punching machine, and the upper die 1 is connected to a hydraulic device of the punching machine, through which the upper die 1 can be driven to move toward the lower die 2, and a feeding mechanism is also included, the feeding mechanism comprising two groups of two feeding rollers 4 respectively mounted on both sides of the lower die 2, the feeding rollers 4 can move the profile, the punching profile is a coil, and when in use, one end of the coil is fed between the two feeding rollers 4 on one side, and the rotation of the feeding rollers 4 can drive the coil to move, and a driving mechanism is also included, the driving mechanism The driving mechanism includes a driving shaft 7 mounted on the mounting frame 3, and a driving wheel 9 is mounted on the driving shaft 7. One of the feeding rollers 4 of the two groups of feeding rollers 4 is connected by a belt, and the two feeding rollers 4 of the same group are meshed by a gear 5. In this way, the two feeding rollers 4 can rotate in relative directions. It also includes an adjustment mechanism, which can adjust the feeding roller 4 connected to the driving wheel 9 through the belt to rotate a preset number of times each time the upper mold 1 and the lower mold 2 come into contact. The adjustment mechanism includes a hollow shaft 10 installed on the feeding roller 4 connected to the driving shaft 7 through a belt, and the hollow shaft 10 is provided with a hollow shaft 10 along its axis. The hollow shaft 10 is coaxially provided with a rotating rod 11 rotatably mounted on the driving shaft 7, and the rotating rod 11 is provided with two sections of threads with opposite rotation directions, and the two sections of threads are matched with moving blocks 15, and the adjusting mechanism also includes a plurality of adjusting plates 13 with the same number as the sliding holes 17, and two connecting rods 16 are rotatably mounted on the adjusting plates 13, and the two connecting rods 16 are respectively rotatably connected with the two moving blocks 15, and the driving shaft 7 is connected with the plurality of adjusting plates 13 through a belt, and when in use, the belt connects the driving wheel 9 and the plurality of adjusting plates 13, and the driving mechanism also includes a plurality of adjusting plates 13 fixed to the driving shaft 7. The upper mold 1 is provided with a rack 6 meshing with the driving gear 5. The rack 6 is driven to move when the upper mold 1 moves toward the lower mold 2 through the above structure. At the same time, the meshing of the rack 6 and the driving gear 5 causes the driving gear 5 to rotate. The driving mechanism includes a one-way bearing 8. The outer ring of the one-way bearing 8 is fixedly connected to the driving wheel 9, and the inner ring of the one-way bearing 8 is fixedly connected to the driving shaft 7. The one-way bearing 8 (the one-way bearing 8 is a bearing that can rotate freely in one direction and is locked in another direction. The one-way bearing 8 is also called an overrunning clutch, which is named according to different industries and functions.The metal shell of the one-way bearing 8 contains many rollers, needle rollers or balls, and the shape of its rolling seat (hole) makes it roll only in one direction, and it will produce great resistance in the other direction). It has the function of only one-way rotation. Therefore, when the upper mold 1 approaches the lower mold 2, the bearing will rotate at this time, but because the driving wheel 9 is connected to the feeding roller 4 through a belt, the driving wheel 9 will not rotate at this time. When the upper mold 1 moves away from the lower mold 2, the bearing is locked at this time, so it is fixed to the driving wheel 9, thereby driving the driving wheel 9 to rotate, realizing the feeding of the coiled material, and utilizing the relative movement between the molds to realize the quantitative feeding of the coiled material, thereby reducing the manufacturing cost and improving the feeding of the coiled material. The accuracy of the material is improved, and the situation that the gap variation caused by manual feeding is large and the waste material is generated is avoided, and the production cost is reduced. In order to be suitable for the stamping of profiles with different gaps during use, a rotating rod 11, a moving block 15 and a connecting rod 16 are set. When it is necessary to adjust the distance of each movement of the coil, the rotating rod 11 is rotated to adjust the spacing between the two moving blocks 15, so that the axial spacing between the multiple adjustment plates 13 and the rotating rod 11 is adjusted accordingly, thereby changing the diameter formed by the multiple adjustment plates 13, and utilizing the elasticity of the belt to achieve different numbers of adjustments of the feed roller 4 under the premise of rotating the same number of circles of the driving wheel 9, and to make rapid adjustments according to different stamping parts, further improving the use effect of the device and enhancing the versatility of the device.

[0033] For other specific implementation schemes of the present invention, see Figure 1-7 The surface of the feed roller 4 is provided with anti-skid patterns, which can increase the friction between it and the coiled material, thereby improving the pushing effect on the coiled material, avoiding sliding during the feeding process, and further improving the accuracy of the feeding process. The adjustment plates 13 are all arc-shaped with openings facing the drive shaft 7. The arc openings can fit the belt more closely, increase the contact area between the belt and the belt, further improve the friction, and avoid the belt slipping during the feeding process. Baffles 14 are installed at both ends of the adjustment plate 13, and the baffles 14 can limit the belt.

[0034] The relative movement between the molds is used to achieve quantitative feeding of the coil material, which reduces the manufacturing cost and improves the accuracy of feeding the coil material, avoiding the large gap changes caused by manual feeding and the large amount of waste generated, thereby reducing the production cost.

[0035] Rapid adjustment according to different stamping parts further improves the use effect of the device and enhances the versatility of the device, while reducing the cost and time required to replace the feeding mechanism and improving production efficiency.
