Description

[0001] A PROCESSING MACHINE FOR CUTTING PVC PROFILES INTO PREDETERMINED SHAPES

[0002] TECHNICAL FIELD

[0003] The invention relates to a processing machine comprising at least one processing unit for cutting workpieces in the form of PVC profiles into predetermined shapes, at least one cutting unit on said processing unit and at least one feeding unit for transporting the workpiece to the processing unit, and having at least one holder for fixing the workpiece during cutting.

[0004] PRIOR ART

[0005] PVC cutting machine is a type of industrial machine used to cut PVC (polyvinyl chloride) material. PVC is a rigid and durable plastic material that is usually found in the form of pipes, profiles, sheets or plates. PVC cutting machines are designed to cut PVC material accurately and precisely. These machines have a wide range of applications in various industries, from the construction sector to the automotive industry. They can be used to cut PVC pipes or profiles into specific lengths, to divide PVC sheets or plates into pieces according to dimensions, or to cut them into customized shapes.

[0006] PVC cutting machines often comprise special cutting blades, control systems for adjusting the cutting speed, and holders to ensure that the material is placed safely and neatly. Some PVC cutting machines can be used manually, while more advanced models can operate automatically and have CNC (Computer Numerical Control) systems. PVC cutting machines are a valuable piece of equipment used to improve work efficiency, reduce material waste, and make cutting processes more precise.

[0007] Application No. CN115256498A, known in the literature, relates to an intelligent machining robot for door and window auxiliary frames with PVC-based profile. The object of the invention is to provide an intelligent machining robot for PVC-based profiles. The intelligent machining robot for PVC-based profile is composed of a workbench and a support frame. The workbench is provided with a cutting groove. The upper part of the support frame is provided with a height adjustment apparatus. The height adjustment apparatus is connected with a concentric square-shaped plate. First angle adjustment device; the first angle adjustment apparatus is connected to a second connecting shaft and a third connecting shaft. The base of the third connecting shaft is associated with a second angle adjustment apparatus. The second angle adjustment apparatus provides connection to a first connecting shaft. The second connecting shaft and the first connecting shaft are connected to a mounting frame in a fixed manner. The drive motors are mounted on the mounting frame, and the two drive motors are arranged opposite each other. The output end of the drive motor is connected with a cutting blade in a fixed manner. In this way, it is possible to work with multiple cutting modes. With the help of angle adjustment, profiles can be cut at various angles.

[0008] Application No. RS1141 U, known in the literature, relates to a structure for cutting PVC moldings at an angle on a rotating work table with pneumatic holders. The object of the invention is to solve the problem of how to cut the PVC moldings exactly in the dimensions of windows, doors, etc. with the structure formed and to ensure that the frame made easily fits into the desired window, door, etc. opening. According to the invention, it consists of a rotary saw of standard design, driven by an electric motor of intended power. The blade of the saw, which can be articulated vertically with its handle, is mounted laterally relative to the electric motor, so that the cutting of PVC can be controlled very precisely. By rotating it vertically, the saw is mounted on a base that is connected to the base of the device. The base plates to the left and right of the work table are fixed to the base. Under the base plates is a round plate with a slot through which the saw blade passes. The handle moves the round plate together with the housing in such a way that it can take any position at a precise angle between degrees.

[0009] One of the biggest problems is that PVC cutting machines have a low cutting ability. Some of the disadvantages caused by this problem are as follows;

[0010] - Decrease in Cutting Quality: Low cutting ability can lead to the inability to cut PVC material neatly and smoothly. Skewing, notches, chips, or incorrect cut lines may appear in the cuts. This can cause problems during installation or use when the PVC does not conform to the desired dimensions. Decrease in Work Efficiency: The low cutting ability of PVC cutting machines can affect work efficiency. Insufficient cutting capabilities of the machine may require more manual intervention, causing cuts to be repeated or corrected. This can lead to slowing down of work processes and loss of time.

[0011] - Increase in Material Waste: Low cutting ability can lead to unnecessary waste of PVC material. Incorrect cuts or irregular cutting lines can result in parts that cannot be used or are discarded. This, in turn, can lead to increased material costs and wasted resources.

[0012] - Safety Problems: Low cutting ability in PVC cutting machines can lead to safety problems. Failure to handle material during the cutting process properly or uncontrolled cutting lines can result in injury to operators or accidents. This can lead to increased safety risks in the workplace.

[0013] - Customer Dissatisfaction: If the products made of PVC material do not meet the desired quality standard due to low cutting quality and cutting errors, it may lead to customer dissatisfaction. Customers may reject faulty or low-quality products, which may affect customer relations and the company's reputation.

[0014] As a result, all the above-mentioned problems have made it imperative to make an innovation in the relevant technical field.

[0015] SUMMARY OF THE INVENTION

[0016] The present invention relates to a processing machine to eliminate the above- mentioned disadvantages and bring the new advantages to the relevant technical field.

[0017] An object of the invention is to produce PVC processing machine with increased cutting ability.

[0018] Another object of the invention is to produce a PVC processing machine that allows V, Y, Arrowhead cutting. In order to achieve all the objects mentioned above and arising from the detailed explanation below, the present invention is a processing machine comprising at least one processing unit for cutting workpieces in the form of PVC profiles into predetermined shapes, at least one cutting unit on said processing unit and at least one feeding unit for transporting the workpiece to the processing unit, and having at least one holder for fixing the workpiece during cutting and allowing Arrowhead cutting. Accordingly, its novelty is that in order to allow V,Y, Arrowhead cutting, the cutting unit comprises at least one upper cutter and at least one lower cutter positioned in the same direction on a first axis, at least one first lower cutter and at least one second lower cutter positioned at a predetermined angle between thereof on said lower cutter, at least one first movement mechanism to move the lower cutter on the first axis, and at least one second movement mechanism to move the lower cutter towards the workpiece on the third axis. Therefore, it is possible to V, Y, Arrowhead cut the workpiece in the processing machine.

[0019] A possible embodiment of the invention is characterized in that the lower cutter is stationary in the second axis. Thus, when the workpiece is moved by the feeding unit, the cutting process is carried out by keeping the lower cutter stationary.

[0020] Another possible embodiment of the invention is characterized in that said first movement mechanism comprises at least one first movement motor, at least one first worm gear shaft at the end of said first movement motor, and at least one first carriage displaceable in the first axis by rotation of said first worm gear shaft around itself. Thus, the workpiece can be cut into the desired shapes with the lower cutter connected to the first carriage moving on the first axis.

[0021] Another possible embodiment of the invention is characterized in that said second movement mechanism comprises at least one second movement motor, at least one second worm gear shaft at the end of said first movement motor, and at least one second carriage displaceable in the second axis by rotation of said second worm gear shaft around itself. Thus, the workpiece has the ability to cut at different angles with the lower cutter connected to the second carriage moving on the third axis. Another possible embodiment of the invention is characterized in that it comprises at least one drilling unit adjacent to the cutting unit. Thus, the processing machine can create the desired holes by drilling the determined positions on the workpiece.

[0022] Another possible embodiment of the invention is that it comprises adjacent to the feeding unit at least one holding unit for holding the workpiece. Thus, the workpiece can be kept ready for processing in the holding unit before being processed, or can be held in stacks while being discharged after being processed.

[0023] Another possible embodiment of the invention is characterized in that the lower cutter and the upper cutter comprise at least one cylindrical blade and at least one blade drive element to rotate said cylindrical blade around itself. Thus, the cutting unit performs the cutting process with the rotation of the cylindrical blades and cuts the workpiece accurately and precisely.

[0024] Another possible embodiment of the invention is characterized in that there are two holders on opposite sides of the cutting unit, and said holder (133) is movable in order to carry out Arrowhead cutting processes. Thus, the workpiece is gripped symmetrically on both sides of the holder, ensuring a stable grip. This allows the workpiece to be supported more evenly during the cutting process and to reduce unwanted vibrations.

[0030] DETAILED DESCRIPTION OF THE INVENTION

[0031] In this detailed description, the subject of the invention is explained by way of example only for a better understanding of the subject, which shall not create any limiting effect.

[0032] Fig. 1 shows a representative perspective view of the processing machine (10) of the invention. Accordingly, the processing machine has a structure specially designed for (10) PVC (polyvinyl chloride) material cutting. Processing machine (10) is used to accurately and precisely cut PVC pipes, profiles, sheets or plates. Processing machine (10) is used in a variety of applications in the construction industry, such as cutting PVC pipes to specific lengths, dividing PVC profiles into pieces according to dimensions, or cutting PVC sheets into customized shapes. The processing machine

[0033] (10) essentially comprises at least one processing unit (13), at least one feeding unit

[0034] (11 ) and at least one holding unit (12). Said holding unit (12) allows the workpiece to be kept ready for processing on the processing machine before being processed or to be held in stacks while being discharged after being processed. Said feeding unit (11) allows the workpieces to be transferred to the processing unit (13) to be processed and to be positioned as desired.

[0035] Fig. 2 shows a representative perspective view of the processing unit (13) in the processing machine (10) of the invention. Accordingly, the processing unit (13) allows the workpiece to be formed into predetermined shapes. There is at least one cutting unit (14) and at least one drilling unit (131) in the processing unit (13). Said drilling unit (131 ) is capable of drilling the predetermined positions on the workpiece. For this purpose, there are multiple drillers (132) positioned at different angles in the drilling unit (131 ). There is at least one holder (133) in the processing unit (13). (See Fig. 5) Said holder (133) is preferably pneumatically moved and allows the workpiece to be clamped by positioning it in a predetermined position before processes such as cutting and drilling. There are two holders (133), preferably on two opposite sides of the cutting unit (14). In addition, the holder (133) has at least a partially moving structure in order to perform Arrowhead cutting. This therefore enables precise cutting on the processing machine (13). Said cutting unit (14) is capable of performing cutting processes such as V, Y, straight cutting, angled cutting, etc. on the workpiece at a predetermined position. For this purpose, there is at least one lower cutter (144) and at least one upper cutter (141) on the cutting unit (14). Said lower cutter (144) and said upper cutter (141 ) are positioned one above the other, allowing the workpiece to be formed in series. There is a cylindrical blade (142) on the lower cutter (144) and the upper cutters (141) on the cutting unit (14). Said cylindrical blades (142) are rotated around themselves by means of a blade drive element (143) to perform the cutting process. The upper cutter (141) is capable of straight cutting and angled cutting on the workpiece. The upper cutter (141 ) is configured such that it is at least partially displaced on a first axis (I) (in the up-down direction when viewed from opposite sides). In addition, the upper cutter (141 ) can be rotated at least partially around itself, allowing for angled cutting.

[0036] Fig. 3 shows a representative perspective view of the cutting unit (14) in the processing machine (10) of the invention. Accordingly, the lower cutter (144) allows V and Y cuts to be made on the workpiece. As mentioned, the lower cutter (144) is located adjacent to the lower part of the upper cutter (141 ). There are two cylindrical blades (142) on the lower cutter (144), including at least a first lower cutter (145) and at least a second lower cutter (146). In order to control these cylindrical blades (142), there are preferably individual blade drive elements (143). With the first lower cutter (145) and the second lower cutter (146) being present on the lower cutter (144), cutting simultaneously from different angles is possible. The lower cutter (144) has the ability to be at least partially displaced in the direction of the first axis (I). In addition, the lower cutter (144) also has the ability to be at least partially displaced in a second axis (II) (the direction of extension in which the workpiece is assumed to be parallel to the ground). For this purpose, the lower cutter (144) comprises at least one first movement mechanism (15) and at least one second movement mechanism (16). The first movement mechanism (15) allows the lower cutter (144) to be displaced on the first axis (I), while the second movement mechanism (16) allows the lower cutter (144) to be displaced on the third axis (III) (the other axis which is parallel to the ground plane and perpendicular to the second axis (II)).

[0037] Fig. 4 shows another representative perspective view of the cutting unit (14) in the processing machine (10) of the invention. Accordingly, the lower cutter (144) is positioned on at least one strut (147) in the cutting unit (14). In the cutting unit (14) first movement mechanism (15) comprises at least one first movement motor (151), at least one first worm gear shaft (152) at the end of said first movement motor (151 ), and at least one first carriage (153) displaceable in the first axis (I) by rotation of said first worm gear shaft (152) around itself. Said first carriage (153) is at least partially displaced in the direction of the extension of said strut (147). The first carriage (153) includes at least one first slide (154) on the strut (147) in order to move linearly on the strut (147).

[0038] In the cutting unit (14) second movement mechanism (16) comprises at least one second movement motor (161), at least one second worm gear shaft (162) at the end of said second movement motor (161), and at least one second carriage (163) displaceable in the third axis (III) by rotation of said second worm gear shaft (162) around itself. Said second carriage (163) is at least partially displaced on the third axis (III) relative to said strut (147). The second carriage (163) includes at least one second slide (164) on the first carriage (153) in order to move on the third axis (III) relative to the strut (147). For the displacement movement required in the cutting unit (14) on the second axis (II), the lower cutter (144) is fixed and the workpiece is moved by the feeding unit (11 ).

[0039] In a possible usage scenario of the invention; the cutting of the welding grooves in which the center bars on the PVC profiles are welded, is carried out by the processing machine (10). Unlike other manufacturers, the lower cutter (144) which cuts in a V- shape, is positioned in the same direction as the upper cutter (141 ) on the first axis (I) and different cuttings can be made simultaneously. In this way, time and energy savings are achieved by preventing separate time losses for two different cutting stations. With this processing machine (10) structure, it is possible to perform cutting processes beyond the cuttings known in the technique and to open the welding grooves. In the same way, in the Y cut type, which supports the butt-to-butt weld, the cutting process can be completed by the cooperation of the lower cutter (144) and the upper cutter (141). In the processing machine (10), the upper cutter (141 ), again in the same way, can perform the cutting process by working on the same axis conjugately in the Arrowhead cutting type through the lower cutter (144) and the movable holder (133). Thus, with the use of the processing machine (10) of the invention, time and labor savings as well as energy savings are achieved. The scope of protection of the invention is specified in the appended claims and cannot be limited to what is described for illustrative purposes in this detailed description. It is clear that a person skilled in the art can produce similar embodiments in the light of what is explained above, without deviating from the main theme of the invention.
