Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic motors, in particular to a pneumatic press with an easily replaceable pressure head. Background Art

[0002] Pneumatic presses are suitable for electronics, instruments, meters, cameras, jewelry, small hardware, clothing, shoes and hats industries; they can perform shearing, punching, blanking, forming, bending, riveting and other processes on thin plates, strips and coils; they are suitable for the processing of non-ferrous metals, plastic parts, etc. However, different processing tasks may require different types and specifications of press heads. Through the device with easy-to-replace press heads, the working mode of the gas press can be quickly adjusted to meet different processing needs;

[0003] Traditional pneumatic presses with easily replaceable pressure heads usually adjust the clamping force on the pressure head by rotating or adjusting bolts, nuts and other parts, and then rotate the nuts in the opposite direction to remove and replace them;

[0004] The traditional pneumatic press with easily replaceable pressure heads has the following problems: since the clamping force needs to be adjusted by manual rotation of bolts, nuts and other parts, the adjustment time may be long, especially when the clamping force needs to be adjusted frequently, which will affect the production efficiency. At the same time, after long-term use, the adjustment of the clamping force of bolts, nuts and other parts is prone to unstable. For this reason, we propose a pneumatic press with easily replaceable pressure heads. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a pneumatic press with an easily replaceable pressure head, which can replace pressure heads of different specifications or types more quickly and flexibly to meet different production needs. At the same time, it can ensure that the workpiece will not be positionally offset or vibrated during the processing, improve the processing accuracy and surface quality, and effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pneumatic press with an easily replaceable pressure head, comprising a base and a screw;

[0007] Base: a placement plate is fixedly connected to the upper surface thereof;

[0008] Screw: It is rotatably connected to the rear end of the upper surface of the base, the top of the screw is fixedly connected with a knob, the middle of the screw is threadedly connected with a fixing plate, a cylinder is provided in the middle of the front end of the fixing plate, the telescopic end of the cylinder is fixedly connected with a supporting plate, a quick release mechanism is provided on the lower surface of the supporting plate, and a pressure head is provided inside the quick release mechanism;

[0009] Among them: it also includes a single-chip microcomputer, which is arranged at the right end of the upper surface of the base. The output end of the single-chip microcomputer is electrically connected to the input end of the cylinder. The pressure heads of different specifications or types can be replaced more quickly and flexibly to adapt to different production needs. At the same time, it can ensure that the workpiece will not have position displacement or vibration during the processing, thereby improving the processing accuracy and surface quality.

[0010] Furthermore, it also includes a control switch, which is respectively arranged on the left and right sides of the front end of the upper surface of the base, and the output ends of the control switches are electrically connected to the input ends of the single-chip microcomputer to avoid accidents caused by erroneous operation by staff.

[0011] Furthermore, it also includes limiting columns, which are fixedly connected to the left and right sides of the rear end of the upper surface of the base, and the upper ends of the limiting columns are slidably connected to the left and right ends of a fixed plate to maintain a stable movement trajectory.

[0012] Furthermore, it also includes a pillar, which is fixedly connected to the rear end of the fixed plate. A guide groove is opened inside the pillar. The inner wall of the guide groove is slidably connected with a fixing rod. The bottom end of the fixing rod is fixedly connected to the rear end of the upper surface of the support plate, which can effectively reduce vibration and shaking.

[0013] Furthermore, the quick-release mechanism includes a fixed cylinder, a sliding groove, an inclined pressure block and a rubber pad. The fixed cylinder is fixedly connected to the front end of the lower surface of the support plate, and the outer surface of the fixed cylinder is provided with evenly distributed sliding grooves. The inner walls of the sliding grooves are slidably connected with inclined pressure blocks, and the inner sides of the inclined pressure blocks are provided with rubber pads. The rubber pads are in contact with the outer surface of a pressure head, thereby improving a more stable clamping force.

[0014] Furthermore, the quick-release mechanism also includes a sliding column and a spring. The sliding columns are slidably connected to the sliding holes at the upper and lower ends of the inner wall of the slide groove. The inner ends of the sliding columns are fixedly connected to the upper and lower ends of the outer side surfaces of the adjacent inclined pressure blocks. Springs are fixedly connected between the upper and lower ends of the outer side surfaces of the inclined pressure blocks and the upper and lower ends of the inner wall of the adjacent slide groove. The springs are sleeved on the outer surface of the sliding column, making it faster and more flexible.

[0015] Furthermore, the quick release mechanism also includes an internal thread ring and a thread groove, the thread groove is opened on the outer surface of the fixing tube, the inner wall of the thread groove is threadedly connected with the internal thread ring, and the internal thread ring is installed in cooperation with evenly distributed inclined pressure blocks to drive the quick release mechanism.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] When the pressure head needs to be replaced after being used for a long time, the internal thread ring is rotated. By rotating the internal thread ring, the internal thread ring moves upward along the thread groove on the fixed cylinder, thereby causing the inner wall of the internal thread ring to gradually separate from the inclined surface on the inclined surface pressure block. When the inner wall of the internal thread ring is completely separated from the inclined surface of the inclined surface pressure block, the spring will rebound outward through its action force, and at the same time drive the sliding column and the inclined surface pressure block to move outward along the inner wall of the sliding groove. As the sliding column and the inclined surface pressure block move outward, the rubber pad on the inclined surface pressure block is gradually separated from the pressure head, ensuring that the pressure head and the rubber pad can be easily detached from the equipment when the pressure head is replaced. Finally, when the rubber pad on the inclined surface pressure block is completely separated from the pressure head, the operator can easily take out the pressure head for replacement or maintenance work, thereby making it faster and more flexible to replace pressure heads of different specifications or types, and adapting to different production needs. At the same time, improving the more stable clamping force can ensure that the workpiece will not have position displacement or vibration during the processing process, thereby improving the processing accuracy and surface quality.

The quick release mechanism 5 includes a fixed cylinder 51, a slide groove 54, an inclined pressure block 57 and a rubber pad 58. The fixed cylinder 51 is fixedly connected to the front end of the lower surface of the support plate 6. The outer surface of the fixed cylinder 51 is provided with evenly distributed slide grooves 54. The inner walls of the slide grooves 54 are slidably connected with inclined pressure blocks 57. The inner sides of the inclined pressure blocks 57 are provided with rubber pads 58. The rubber pads 58 are in contact with the outer surface of a pressure head 4. The quick release mechanism 5 also includes a slide column 55 and a spring 56. The slide column 55 is slidably connected to the sliding holes at the upper and lower ends of the inner wall of the slide groove 54. The inner side ends of the slide column 55 are fixedly connected to the upper and lower ends of the outer side surfaces of the adjacent inclined pressure blocks 57. The upper and lower ends of the outer side surfaces of the inclined pressure blocks 57 are connected to the inner wall of the adjacent slide groove 54. A spring 56 is fixedly connected between the upper and lower ends of the wall, and the spring 56 is sleeved on the outer surface of the sliding column 55. The quick-release mechanism 5 also includes an internal thread ring 52 and a thread groove 53. The thread groove 53 is arranged on the outer surface of the fixed cylinder 51. The inner wall of the thread groove 53 is threadedly connected with the internal thread ring 52. The internal thread ring 52 is installed in conjunction with evenly distributed inclined surface pressure blocks 57. Then the telescopic end of the cylinder 8 drives the support plate 6 to move downward, and the support plate 6 drives the pressure head 4 fixed between the inclined surface pressure blocks 57 to move downward to apply pressure on the workpiece, so as to realize the forming, punching, stamping and other processing operations on the workpiece. When the support plate 6 moves downward, it drives the fixed rod 14 to slide on the inner wall of the guide groove, and then the support plate 6 is moved in During the pressing process, a stable motion trajectory can be maintained, which can effectively reduce vibration and shaking, ensure that the pressure head 4 applies uniform pressure to the workpiece, and improve the processing quality and precision. When the distance between the cylinder 8 and the workpiece needs to be adjusted, the knob 9 is rotated, and the knob 9 drives the screw 12 to rotate. The screw 12 is threadedly connected with the fixed plate 10, thereby driving the fixed plate 10 to move downward and slide on the outer surfaces of the two limit columns 11, thereby driving the cylinder 8 and the pressure head 4 in the quick-release mechanism 5 to move downward, which can achieve precise adjustment of the distance between the cylinder and the workpiece, and can ensure accuracy during the adjustment process to meet the requirements of different workpiece processing. When the pressure head 4 needs to be replaced after long-term use, the internal thread ring 52 is rotated. By rotating the internal thread ring 52,The internal thread ring 52 moves upward along the thread groove 53 on the fixed cylinder 51, thereby causing the inner wall of the internal thread ring 52 to gradually separate from the inclined surface of the inclined surface pressure block 57. When the inner wall of the internal thread ring 52 is completely separated from the inclined surface of the inclined surface pressure block 57, the spring 56 will rebound outward through its action force, and at the same time drive the sliding column 55 and the inclined surface pressure block 57 to move outward along the inner wall of the sliding groove 54. As the sliding column 55 and the inclined surface pressure block 57 move outward, the rubber pad 58 on the inclined surface pressure block 57 is gradually separated from the pressure head 4, ensuring that the pressure head 4 and the rubber pad 58 can be easily separated from the equipment when the pressure head 4 is replaced. Finally, when the rubber pad 58 on the inclined surface pressure block 57 is completely separated from the pressure head 4, the operator can easily take out the pressure head 4 for replacement or maintenance. Replacing pressure heads of different specifications or types becomes faster and more flexible, adapting to different production needs. At the same time, the more stable clamping force is improved to ensure that the workpiece will not have position displacement or vibration during the processing, thereby improving the processing accuracy and surface quality.

[0026] The single chip microcomputer 13 is also included. The single chip microcomputer 13 is arranged at the right end of the upper surface of the base 2. The output end of the single chip microcomputer 13 is electrically connected to the input end of the cylinder 8.

[0027] The working principle of a pneumatic press with an easily replaceable pressure head provided by the utility model is as follows: a workpiece to be processed is placed on a placement plate 1, and then the single-chip microcomputer 13 is regulated to operate by pressing the control switches 3 on both sides, and the single-chip microcomputer 13 receives signals to regulate the operation of the cylinder 8. By setting two control switches 3, accidents caused by erroneous operation by staff can be avoided. For example, two control switches 3 need to be pressed at the same time to start the pneumatic press. This design can effectively reduce the risk of false triggering and improve operational safety. Then the telescopic end of the cylinder 8 drives the support plate 6 to move downward, and the support plate 6 drives the pressure head 4 fixed between the inclined pressure block 57 to move downward to apply pressure. On the workpiece, forming, punching, stamping and other processing operations are carried out on the workpiece. When the support plate 6 moves downward, it drives the fixing rod 14 and slides on the inner wall of the guide groove. Then, the fixing rod 14 slides on the inner wall of the guide groove, and the support plate 6 can maintain a stable movement trajectory during the pressing process, which can effectively reduce vibration and shaking, ensure that the pressure head 4 applies uniform pressure to the workpiece, and improve the processing quality and accuracy. When it is necessary to adjust the distance between the cylinder 8 and the workpiece, the knob 9 is rotated, and the knob 9 drives the screw 12 to rotate. The screw 12 is threadedly connected with the fixing plate 10, thereby driving the fixing plate 10 to move downward and slide on the outer surfaces of the two limit columns 11, thereby bringing The moving cylinder 8 and the pressure head 4 in the quick-release mechanism 5 move downward, which can realize the precise adjustment of the distance between the cylinder and the workpiece, and can ensure the accuracy of the adjustment process to meet the requirements of different workpiece processing. When the pressure head 4 needs to be replaced after long-term use, the internal thread ring 52 is rotated. By rotating the internal thread ring 52, the internal thread ring 52 moves upward along the thread groove 53 on the fixed cylinder 51, thereby causing the inner wall of the internal thread ring 52 to gradually separate from the inclined surface of the inclined surface pressure block 57. When the inner wall of the internal thread ring 52 is completely separated from the inclined surface of the inclined surface pressure block 57, the spring 56 will rebound outward through its action force, and at the same time drive the sliding column 55 and the inclined surface pressure block 57 7 moves outward along the inner wall of the slide groove 54. As the slide column 55 and the inclined surface pressing block 57 move outward, the rubber pad 58 on the inclined surface pressing block 57 is gradually separated from the pressure head 4, ensuring that when the pressure head 4 is replaced, the pressure head 4 and the rubber pad 58 can be easily separated from the equipment. Finally, when the rubber pad 58 on the inclined surface pressing block 57 is completely separated from the pressure head 4, the operator can easily take out the pressure head 4 for replacement or maintenance. Replacing pressure heads of different specifications or types becomes faster and more flexible, adapting to different production needs. At the same time, the more stable clamping force is improved to ensure that the workpiece will not be positionally offset or vibrated during the processing, thereby improving the processing accuracy and surface quality.
