Description

Technical Field

[0001] This utility model relates to the field of computer saw blade cutting technology, and in particular to a computer saw blade cutting machine. Background Technology

[0002] In existing computer-controlled saw blade cutting machines, a fixed baffle is typically installed vertically at the feed inlet to prevent cutting debris from splashing out. However, this design has significant drawbacks: First, raising and lowering the baffle requires considerable driving force. If the baffle is slightly deformed due to long-term use or debris accumulation, it is difficult to close completely, reducing its splash-proof effect. Second, cleaning and maintenance require lifting the entire baffle. Even if there is debris accumulation in a localized area, frequent operation of the entire baffle is still necessary, increasing downtime and potentially allowing debris to seep out from the gaps at the bottom of the baffle. Third, disassembling and maintaining the entire baffle requires multiple people, making the operation complex and posing safety hazards. Furthermore, the lateral movement of the traditional saw blade assembly relies on a single motor drive, which is prone to positional shifts during cutting due to inertia or load changes, affecting cutting accuracy.

[0003] Therefore, the inventors designed a computer-controlled saw blade cutting machine to solve the above problems. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, this utility model provides a computer saw blade cutting machine, which aims to solve the problems of poor anti-splash effect of the overall baffle, inconvenient maintenance, and easy to affect the cutting accuracy of traditional saw blade assemblies in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a computer-controlled saw blade cutting machine, comprising a processing table and an auxiliary frame. The processing table has symmetrically arranged outwardly extending extension plates on both sides, and the auxiliary frame spans above the two extension plates. A transversely penetrating cutting groove is formed in the middle of the processing table near the material input port. A transverse saw blade assembly is located below the cutting groove, comprising a liftable saw blade, the top of which can pass through the cutting groove for cutting operations. The auxiliary frame contains a plate clamping assembly and a segmented anti-splash assembly. The segmented anti-splash assembly includes several independent baffle units arranged transversely along the material input port, and a clamping and lifting unit corresponding to drive each independent baffle unit. The clamping and lifting unit includes an outward-expanding cylinder and a gear-driven clamp. Each independent baffle unit has a rack cavity inside, and the outward-expanding cylinder drives the gear-driven clamp to mesh with the rack cavity to control the baffle lifting.

[0006] Based on the above, the beneficial effects of a computer-controlled saw blade cutting machine are that it solves the problems of poor anti-splash effect of the overall baffle, inconvenient maintenance, and easy impact on the cutting accuracy of traditional saw blade assemblies in the existing technology; mainly reflected in:

[0007] 1. By setting up a segmented anti-splash component, each independent baffle unit can be raised and lowered independently under the control of the outward expansion cylinder and gear drive clamp. This not only reduces the driving force required for the raising and lowering of the independent baffle unit, but also ensures that even if individual independent baffle units are deformed due to long-term use, the overall anti-splash effect will not be affected.

[0008] 2. This utility model adopts a segmented independent baffle unit. When cleaning or maintenance is required, only the relevant independent baffle unit needs to be operated, without lifting the entire baffle, which reduces downtime. In addition, the bottom of the independent baffle unit is equipped with a wear-resistant buffer rubber strip, which further prevents the problem of debris seeping out from the bottom gap.

[0009] 3. The transverse saw blade assembly of this utility model adopts a design of transverse drive component, vertical drive cylinder and saw blade component. The transverse drive component includes transverse drive motor, lead screw and internal thread block. Compared with traditional single motor drive cutting, this structure can effectively reduce position displacement caused by inertia or load changes during the cutting process, and improve the cutting accuracy and stability.

[0010] Furthermore, the gear drive clamp includes two symmetrically arranged jaws, and each jaw has several drive gears arranged axially at intervals on its inner side. The drive gears are driven by a gear motor, and adjacent drive gears form a synchronous transmission structure through a transmission belt. The inner walls on both sides of the rack cavity are provided with rack structures that mesh with the drive gears.

[0011] Based on the above, the beneficial effect of multiple drive gears and rack structures meshing is that it enables the upward control of independent baffle units, thereby improving their positional accuracy during the upward process. This not only ensures that the independent baffle units can accurately protect the required positions, but also reduces operational errors caused by mechanical errors. The beneficial effect of the synchronous transmission structure formed by the transmission belt between adjacent drive gears is that it enables all drive gears to maintain a consistent speed and direction, avoiding slippage or loss of synchronization that may occur with a single drive gear.

[0012] Furthermore, when the expansion cylinder is not activated, the gear drive clamp disengages from the rack structure, and the independent baffle unit naturally moves down to the material plate input port under gravity to form protection; when the expansion cylinder is activated, the drive gear of the gear drive clamp meshes with the upper end of the rack structure, and the independent baffle unit is driven to rise through the gear motor.

[0013] Based on the above, the beneficial effects of the independent baffle unit naturally moving downward under gravity after the gear drive clamp disengages from the rack structure are that it simplifies the operation process of the equipment, improves the flexibility and response speed of the equipment, and only performs the meshing operation when the baffle needs to be raised, thus extending the service life of key components and reducing maintenance costs.

[0014] Furthermore, the transverse saw blade assembly includes a transverse drive component, a vertical drive cylinder, and a saw blade assembly. The transverse drive component includes a transverse drive motor, a lead screw, and an internal thread block. The lead screw is located at the output end of the transverse drive motor, and the internal thread block is threaded onto the lead screw. The vertical drive cylinder is located at the upper end of the internal thread block, and the saw blade assembly is located at the output end of the vertical drive cylinder.

[0015] Based on the above, the beneficial effect of the screw and the internal thread block threaded engagement is to achieve precise positioning of the saw blade assembly in the lateral direction; the beneficial effect of the vertical drive cylinder is to flexibly adjust the height of the saw blade according to different processing requirements, which not only improves the adaptability of the equipment, but also meets the cutting requirements of plates of different thicknesses, thus enhancing the multi-functionality of the equipment.

[0016] Furthermore, the saw blade assembly includes a saw blade motor and a saw blade disposed at the output end of the saw blade motor, the saw blade passing through the cutting groove to cut the material plate.

[0017] Furthermore, the processing machine is also equipped with several parallel sliding rails and several pushing cylinders. The sliding rails are perpendicular to the inner side of the cutting groove in the horizontal direction. Sliding plates are slidably fitted on the sliding rails. Several material plate pushing blocks are evenly arranged on the upper end of the sliding plates. Each material plate pushing block is connected to the output end of one of the pushing cylinders.

[0018] Based on the above, the beneficial effect of controlling each material plate pusher block with an independent pusher cylinder is to achieve point-by-point pushing. Compared with the traditional large-area pushing method, it is easy to cause uneven local force, which can lead to material plate displacement or jamming and affect feeding accuracy.

[0019] Furthermore, the bottom of each independent baffle unit is provided with a wear-resistant buffer rubber strip, and the gap between each independent baffle unit is 0.3-0.5mm.

[0020] Based on the above, the beneficial effect of the wear-resistant buffer rubber strip is to fill the tiny gaps between the independent baffle unit and the processing table, preventing the chips generated during the cutting process from seeping out from the bottom, thereby improving the overall anti-splashing effect; the beneficial effect of setting the gap between each independent baffle unit to 0.3-0.5mm is to ensure sufficient flexibility and freedom of movement, while avoiding chip leakage problems caused by excessive gaps.

[0021] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the following description, in conjunction with the accompanying drawings and specific embodiments, will further explain this utility model. Attached Figure Description

Detailed Implementation

[0028] like Figures 1-5As shown, a computer-controlled saw blade cutting machine includes a processing table 1 and an auxiliary frame 2. The processing table 1 has symmetrically arranged outwardly extending extension plates on both sides, and the auxiliary frame 2 spans above the two extension plates. A transversely penetrating cutting groove 11 is formed in the middle of the processing table 1 near the material input port. A transverse saw blade assembly 3 is located below the cutting groove 11. The transverse saw blade assembly 3 includes a liftable saw blade 332, the top of which can pass through the cutting groove 11 for cutting operations. The auxiliary frame 2 is equipped with a plate clamping assembly 6 and a segmented anti-splash assembly 7. The segmented anti-splash assembly 7 includes several independent baffle units 71 arranged laterally along the material plate input port, and a clamping and lifting unit 72 that drives each independent baffle unit 71. The clamping and lifting unit 72 includes an outward expansion cylinder 721 and a gear drive clamp 722. The independent baffle unit 71 has a rack cavity 711 inside. The outward expansion cylinder 721 drives the gear drive clamp 722 to mesh with the rack cavity 711 to control the baffle lifting.

[0029] The gear drive clamp 722 includes two symmetrically arranged jaws 7221. Each jaw 7221 has a plurality of drive gears 7222 arranged axially on its inner side. The drive gears 7222 are driven by a gear motor 7223. Adjacent drive gears are connected by a transmission belt 7224 to form a synchronous transmission structure. The inner walls of both sides of the rack cavity 711 are provided with rack structures 7111 that mesh with the drive gears 7222.

[0030] When the expansion cylinder 721 is not activated, the gear drive clamp 722 disengages from the rack structure 7111, and the independent baffle unit 71 naturally moves down to the material plate input port under the action of gravity to form protection; when the expansion cylinder 721 is activated, the drive gear 7222 of the gear drive clamp 722 meshes with the upper end of the rack structure 7111, and drives the independent baffle unit 71 to rise through the gear motor 7223.

[0031] The transverse saw blade assembly 3 includes a transverse drive component 31, a vertical drive cylinder 32, and a saw blade assembly 33. The transverse drive component 31 includes a transverse drive motor 311, a lead screw 312, and an internal thread block 313. The lead screw 312 is located at the output end of the transverse drive motor 311, and the internal thread block 313 is threaded onto the lead screw 312. The vertical drive cylinder 32 is located at the upper end of the internal thread block 313, and the saw blade assembly 33 is located at the output end of the vertical drive cylinder 32.

[0032] The saw blade assembly 33 includes a saw blade motor 331 and a saw blade 332 disposed at the output end of the saw blade motor 331. The saw blade 332 passes through the cutting groove 11 to cut the material plate.

[0033] The processing machine table 1 is also provided with several parallel sliding rails 12 and several pushing cylinders 14. The sliding rails 12 are perpendicular to the inner side of the cutting groove 11 in the horizontal direction. Sliding plates 13 are slidably fitted on the sliding rails 12. Several material plate pushing blocks 131 are evenly arranged on the upper end of the sliding plates 13. Each material plate pushing block 131 is connected to the output end of a pushing cylinder 14.

[0034] The bottom of the independent baffle unit 71 is provided with a wear-resistant buffer rubber strip 712, and the gap between each independent baffle unit 71 is 0.3-0.5mm.

[0035] In summary, the specific implementation of this utility model is as follows: After 18 sheets of material number 1.582 are positioned along the left side of the processing table 1, they are manually pushed into the processing table 1. After the sheet is in place, the independent baffle unit 71 of the segmented anti-splash component 7 falls naturally after the gear driven by the expansion cylinder 721 of the clamping lifting unit 72 is released. The material plate input port is closed by the wear-resistant buffer rubber strip 712 at the bottom. At this time, the horizontal drive motor 311 of the transverse saw blade assembly device 3 drives the lead screw 312 to drive the internal thread block 313 to move laterally. The vertical drive cylinder 32 lifts the saw blade assembly 33, and the saw blade 332 passes through the cutting groove 11 to complete the first cut (i.e., remove the excess length first).

[0036] After the initial cut, the expansion cylinder 721 of the clamping and lifting unit 72 is activated, and the gear drive clamp 722 meshes with the upper part of the rack inner cavity 711. The gear motor 7223 lifts the independent baffle unit 71 of the corresponding width through the drive gear 7222. At the same time, the pushing cylinder 14 drives the material plate pusher 131 of the sliding plate 13 to push the plate to the secondary cutting position. At this time, the user removes the excess length of the plate. The expansion cylinder 721 drives the gear drive clamp 722 to release the independent baffle unit 71 again. After the independent baffle unit 71 closes again... Then, the saw blade 332 performs a second cut. After the second cut is completed, the outward expansion cylinder 721 drives the gear drive clamp 722 to clamp the independent baffle unit 71. The gear drive clamp 722 meshes with the upper part of the rack inner cavity 711 and is driven to rise by the gear motor 7223. The material plate pusher 131 continues to push the plate to the third cut position. The user takes away the plate that has been cut in the first cut. The saw blade 332 completes the third cut. Finally, the pusher cylinder 14 drives the material plate pusher 131 to push out the remaining plate in sections. The user takes away the cut finished products in sequence.

[0037] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
