Description

Technical Field

[0001] The utility model relates to the field of plastic parts processing, in particular to a punching and cutting structure for plastic parts processing. Background Art

[0002] Plastic parts are various parts or components made of plastic materials, and are widely used in manufacturing industries such as automobiles, electronics, toys, home appliances, instruments and meters, wires and cables, construction equipment, communications electronics, aerospace, and daily hardware.

[0003] The stamping and cutting structure used for plastic parts processing is a mechanical equipment structure specially used for plastic parts processing. It combines the two processes of stamping and cutting, and realizes the precise cutting and forming of plastic parts through a specific mechanical structure and movement mode.

[0004] Patent application number 202322376514.4 discloses a punching machine for processing plastic products, which relates to the technical field of punching equipment. The utility model comprises a frame, a slide bar, and a tool holder. Brackets located at the front end of a collection trough are fixedly mounted on both sides of the frame, and limit screws are threadedly connected to both sides of the brackets.

[0005] However, the traditional stamping and cutting structure used in plastic parts processing is prone to vibration caused by the contact between the cutter and the plastic part during punching, which is aggravated by its own elastic buffering effect. It is easy to cause the cutting line to deviate and the shape to be distorted, resulting in inaccurate cutting. Workers who need to touch the cutting area are prone to injury, posing an obvious safety hazard. Utility Model Content

[0006] The utility model discloses a punching and cutting structure for processing plastic parts, which aims to solve the technical problem that the vibration generated when the cutter contacts the plastic part at the moment of punching and cutting will be aggravated by its own elastic buffering effect, which may easily cause the deviation of the cutting line and the distortion of the shape, resulting in inaccurate cutting. In addition, the workers may be easily injured when they need to contact the cutting area, which poses obvious safety hazards.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A punching and cutting structure for processing plastic parts, comprising an operating table and:

[0009] Fixing mechanism: The fixing mechanism is arranged on the top outer wall of the operating table;

[0010] Cutting mechanism: The cutting mechanism is arranged inside the operating table, and a lower cutting component is provided inside the operating table. The lower cutting component includes an assembly bin, a second telescopic rod is provided on the bottom inner wall of the assembly bin, and a lower blade is fixed to the output end of the second telescopic rod. A collecting groove is provided on the top outer wall of the operating table, an assembly seam is provided on the bottom inner wall of the collecting groove, and an upper cutting component is provided on the top outer wall of the operating table.

[0011] In this case, the method of simultaneous cutting from top to bottom is adopted. By increasing the number and distribution of cutting points, the vibration generated during the cutting process is dispersed and balanced, making the cutting force more uniform, and more accurately controlling the straightness and verticality of the cutting line, reducing the deviation caused by vibration, making the cutting process more stable, and ensuring the best cutting effect.

[0012] In a preferred embodiment, the upper cutting assembly includes an assembly frame, which is arranged on the top outer wall of the operating table, and a first telescopic rod is arranged on the top inner wall of the assembly frame, one end of the first telescopic rod is connected to an air pump, a sliding rod is arranged on the top outer wall of the operating table, a mounting plate is slidably mounted on the circumferential outer wall of the sliding rod, an upper blade is arranged on the bottom outer wall of the mounting plate, and the output end of the first telescopic rod is connected to the top outer wall of the mounting plate.

[0013] The upper cutting assembly is set on the operating table, and the air pump provides power to the first telescopic rod. The power drives the upper blade on the mounting plate and the bottom outer wall to slide on the outer wall of the slide rod and adjust to the required cutting position. At the same time, the lower blade is driven by the second telescopic rod, passes through the assembly seam and rises to a position opposite to the upper blade. The blades of the two are set relative to each other to ensure that they can be precisely aligned during the cutting operation, thereby achieving efficient and accurate cutting effects.

[0014] In a preferred solution, the fixing mechanism includes two connecting rods, both of which are arranged on the top outer wall of the operating table, and one end of the connecting rod is connected to the inner wall of one side of the assembly frame, a slide groove is provided on the top outer wall of the connecting rod, a slider is slidably installed on the inner wall of the slide groove, a support frame is connected to the top outer wall of the slider, two sets of fixing frames are provided on the top outer wall of the support frame, and an installation groove is provided on the top outer wall of the fixing frame.

[0015] The plastic parts to be cut are clamped by the mounting groove on the fixed frame, avoiding cutting errors caused by movement or offset of the plastic parts during the cutting process. The slider then drives the support frame to slide in the slide groove on the top of the connecting rod, ensuring that the plastic parts to be cut move along the predetermined path to the cutting area, thereby achieving efficient and accurate cutting, avoiding direct contact between workers and the cutting area, thereby greatly reducing the risk of cutting fingers and improving safety of use.

[0016] As can be seen from the above, a stamping and cutting structure for processing plastic parts includes an operating table, and also includes: a fixing mechanism: the fixing mechanism is arranged on the top outer wall of the operating table; a cutting mechanism: the cutting mechanism is arranged inside the operating table, and a lower cutting assembly is provided inside the operating table.

The stamping and cutting structure for processing plastic parts provided by the utility model has the technical effect of improving cutting accuracy and safety of use.

[0027] The upper cutting assembly and the lower cutting assembly are used in conjunction with each other.

[0028] In a specific embodiment, a method of simultaneous cutting up and down is adopted, and the number and distribution of cutting points are increased to disperse and balance the vibration generated during the cutting process, so that the cutting force is more uniform, the straightness and verticality of the cutting line are more accurately controlled, and the deviation caused by vibration is reduced, making the cutting process more stable and ensuring the best cutting effect.

[0029] Reference Figure 2 、 Figure 3 and Figure 4In a preferred embodiment, the upper cutting assembly includes an assembly frame 3, which is arranged on the top outer wall of the operating table 1, and a first telescopic rod 15 is provided on the top inner wall of the assembly frame 3, one end of the first telescopic rod 15 is connected to the air pump 9, and a sliding rod 10 is provided on the top outer wall of the operating table 1, and a mounting plate 11 is slidably mounted on the circumferential outer wall of the sliding rod 10, and an upper blade 12 is provided on the bottom outer wall of the mounting plate 11, and the output end of the first telescopic rod 15 is connected to the top outer wall of the mounting plate 11.

The power drives the mounting plate 11 and the upper blade 12 on the bottom outer wall thereof to slide on the outer wall of the slide rod 10 and adjust to the required cutting position. At the same time, the lower blade 16 is driven by the second telescopic rod 17, passes through the assembly seam 13 and rises to a position opposite to the upper blade 12, performing simultaneous cutting up and down. After cutting, the plastic part can fall into the collection trough 18 through the leakage hole at the top of the support frame 5 and slide out smoothly along its inclined surface.
