Description

Technical Field

[0001] This invention relates to the field of steel support processing technology, specifically to a processing device for a steel support frame for a school desk. Background Technology

[0002] In the production and processing of steel frames for school desks, flat steel is one of the core raw materials. It needs to be cut to a predetermined length according to the design dimensions of the steel frame before subsequent bending, welding, and other processes. Currently, most processing equipment on the market for cutting flat steel has only a single cutting function; it can only cut the flat steel and cannot simultaneously complete length detection and chip removal.

[0003] In actual processing, operators need to use additional measuring tools to mark the flat steel to a fixed length before sending the marked flat steel to the cutting equipment for cutting. This not only increases the amount of manual labor, but also makes it easy for manual length marking to be inaccurate, resulting in the flat steel not meeting the requirements after cutting and causing material waste.

[0004] Meanwhile, the chips generated during the cutting process will accumulate on the equipment's tracks, blades, and other parts. If they are not cleaned in time, they will affect the feeding accuracy and cutting quality of the flat steel, and may also lead to accelerated blade wear and frequent equipment failures. Regular shutdowns for cleaning are required, which seriously affects processing efficiency and cannot meet the needs of large-scale production of school desk steel frames.

[0005] In view of this, we propose a processing equipment for steel supports for school desks. Summary of the Invention

[0006] The purpose of this invention is to provide a processing device for steel desk supports, to solve the problems mentioned in the background art regarding existing flat steel processing equipment for steel desk supports, such as single cutting, the need for manual length adjustment, and chip accumulation affecting processing efficiency and quality. To achieve the above objective, this invention provides the following technical solution: a processing device for steel desk supports, comprising a cabinet, a track frame fixedly mounted on the cabinet via a bracket, a slot for fitting flat steel for steel desk supports on the top of the track frame, a vertically adjustable cutting machine fixedly mounted on one side of the cabinet, and a notch in the middle of the track frame for the cutting machine blade to pass through.

[0007] An inner frame adapted to the track frame is provided in the notch. A chip groove is provided on the bottom wall of the inner frame. A slide plate is slidably embedded in the chip groove. A top spring for lifting the slide plate is fixedly connected to the bottom of the chip groove.

[0008] The inner bottom wall of the inner frame has a column hole that communicates with the chip groove, and a column pin is slidably embedded in the column hole.

[0009] The inner wall of the track frame on the cut side of the flat steel is fixedly embedded with a magnetic strip, and the inner bottom wall of the track frame on the cut side is provided with a bottom groove, and the end of the bottom groove is provided with a slope.

[0010] The notch has a top-opening structure, and the inner frame is vertically slidably connected to the inner wall of the notch via a slide rail. A return spring that pushes the inner frame upward is fixedly connected to the bottom of the notch.

[0011] The outer frame covering the blade is fixedly installed on the outer shell of the cutting machine, and the lower end face of the outer frame corresponds to the upper end face of the inner frame.

[0012] The inner frame sidewall has an inclined groove aligned with the top edge of the chip groove, and the lower side of the notch sidewall has an opening that communicates with the chip collection structure inside the cabinet.

[0013] Preferably, the elasticity of the top spring is matched with the weight of the chips generated by cutting the flat steel of the desk steel frame, ensuring that the slide can be pushed down when the chips accumulate to a preset amount.

[0014] Preferably, when the slide plate moves downward, it can compress the air in the chip groove. The compressed air pushes the pin upward along the pin hole, so that the top of the pin is inserted into the flat steel cutting opening to temporarily limit the flat steel.

[0015] Preferably, the length of the magnetic strip is adapted to the preset forward movement distance after the flat steel is cut, so that the flat steel passing through the inner frame cutting point can acquire temporary magnetism.

[0016] Preferably, the depth of the bottom groove is adapted to the preset amount of chips to be adsorbed, the extension direction of the ramp is consistent with the feeding direction of the flat steel, and the flat steel moves to the ramp position and leaves the magnetization range of the magnetic strip and loses its magnetism.

[0017] Preferably, the spring force of the return spring is greater than the weight of the inner frame itself, ensuring that the inner frame is flush with the top surface of the track frame when no external force is applied.

[0018] Preferably, when the cutting machine blade moves down, the outer frame first contacts the inner frame and pushes the inner frame down, so that the top surface of the inner frame is lower than the top surface of the track frame to completely expose the flat steel to be cut.

[0019] Preferably, the inclined groove is tilted towards the inside of the notch. When the inner frame moves down to the cutting position, the inclined groove and the through opening are precisely aligned, which can discharge the excess chips that are higher than the top edge in the chip groove to the chip collection structure.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. It integrates flat steel cutting, length detection, and chip control, eliminating the need for additional length detection and chip removal devices. The structure is simple and the manufacturing cost is low. It solves the problems of existing equipment requiring manual assistance for length determination and chip accumulation affecting processing. It significantly improves the automation and processing accuracy of flat steel processing for school desk steel frames, reduces manual intervention costs, avoids material waste caused by length deviation, and is suitable for the large-scale production needs of school desk steel frames.

[0022] 2. By combining the top spring, sliding plate, and pin with compressed air, and utilizing the correlation between the amount of chips generated during cutting and the forward movement of the flat steel, automatic detection and abnormality alerts for flat steel length can be achieved. No manual measurement or marking is required, making operation convenient and detection accuracy high, effectively ensuring the consistency of flat steel cutting length.

[0023] 3. By using magnetic strips to temporarily magnetize the flat steel, combined with the bottom groove and slope structure, the chips are automatically adsorbed, transferred and discharged, keeping the processing area clean, avoiding chip residue from affecting the feeding accuracy and cutting quality of the flat steel, reducing the workload of manual chip cleaning, and the collected chips can be recycled and reused, which is in line with the concept of green processing.

[0024] 4. Through the linkage structure of the outer frame and the inner frame, it is ensured that the flat steel to be cut is fully exposed during cutting, avoiding problems such as uneven cut and incomplete cutting caused by the inner frame blocking the cut. This improves the processing quality of the flat steel cut of the desk steel frame, reduces the subsequent grinding process, and lowers the processing cost.

[0025] The reset spring allows for automatic reset of the inner frame, ensuring smooth feeding of the flat steel.

[0026] 5. The design of the inclined groove and the through-hole can accurately control the amount of chips in the chip groove, avoiding excessive or insufficient chip accumulation that may affect the accuracy of fixed length detection. At the same time, it can realize the timely discharge of excess chips, reduce the situation of chips wrapping around the tool, extend the tool life, and reduce equipment maintenance costs.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 8 The present invention provides a technical solution: a processing equipment for a steel support frame for a school desk, including a cabinet 1, a track frame 3 fixedly mounted on the cabinet 1 by a bracket 2, and a slot 4 for a flat steel for the steel support frame for the school desk opened on the top of the track frame 3. The flat steel can be pushed forward smoothly along the slot 4 to ensure feeding accuracy. The width of the slot 4 is slightly larger than the thickness of the flat steel to ensure that the flat steel does not deviate when moving forward, and at the same time avoids excessive gaps that affect feeding stability.

[0038] A vertically adjustable cutting machine 5 is fixedly installed on one side of the cabinet 1. The cutting machine 5 is a CNC lifting cutting machine, and the blade is made of high-speed steel to meet the needs of flat steel cutting operations. The blade of the cutting machine 5 corresponds to the middle position of the track frame 3. The middle of the track frame 3 has a notch 6 to allow the blade of the cutting machine 5 to pass smoothly. The width of the notch 6 is slightly larger than the thickness of the blade to ensure smooth and interference-free cutting, while also ensuring the overall structural strength of the track frame 3.

[0039] An inner frame 7, adapted to the track frame 3, is installed within the notch 6. The shape of the inner frame 7 matches that of the notch 6. A chip groove 8 is formed on the inner bottom wall of the inner frame 7. The length of the chip groove 8 is adapted to the width of the track frame 3. A sliding plate 9 is slidably embedded inside the chip groove 8. The outer wall of the sliding plate 9 is fitted against the inner wall of the chip groove 8 to ensure stable compression of the air inside the groove during the sliding process of the sliding plate 9. A top spring 10, which is a cylindrical helical spring, is fixedly installed at the bottom of the chip groove 8 to lift the sliding plate 9. The elastic force matches the weight of the chips generated by cutting the flat steel of the desk steel frame, achieving a precise match between the chip accumulation and the forward movement length of the flat steel.

[0040] The inner bottom wall of the inner frame 7 has a column hole 11 that connects to the chip groove 8. A pin 12 is slidably embedded inside the column hole 11. The top of the pin 12 is rounded to prevent scratching the flat steel cross-section during the cutting process. The slide plate 9 moves down to compress the air inside the chip groove 8. The compressed air pushes the pin 12 upward along the column hole 11, causing the top of the pin 12 to extend and insert into the flat steel cutting position. This limits and stops the flat steel from moving beyond the preset length, preventing it from being transported beyond its travel range.

[0041] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, a magnetic strip 13 is embedded and fixed on the inner wall of the track frame 3 on the side where the flat steel is cut. The magnetic strip 13 is a permanent magnet structure, and its length matches the preset forward movement distance of the flat steel before cutting. When the flat steel passes through the cutting position, it can be instantly magnetized and obtain temporary magnetic attraction. The embedded end face of the magnetic strip 13 is flush with the inner wall of the track frame 3, so it will not hinder the linear transport of the flat steel.

[0042] The inner bottom wall of the cutting side of the track frame 3 has a bottom groove 14 to accommodate the small amount of chips generated during the cutting operation. When the magnetized flat steel is conveyed forward, the bottom can attract the chips in the chip groove 8 and carry them into the bottom groove 14. Due to the space limitation of the bottom groove 14, the amount of chips attracted by the flat steel in a single operation is constant. When the chips in the chip groove 8 are completely attracted and carried away by the flat steel, it means that the forward movement distance of the flat steel has reached the preset cutting length. The slide plate 9 loses the chip load and moves upward to reset under the drive of the top spring 10. The air pressure inside the chip groove 8 returns to normal, the pin 12 falls back to reset, the restriction on the flat steel is released, and the flat steel can be conveyed normally.

[0043] If the forward movement distance of the flat steel is insufficient, chips remain inside the chip groove 8, the slide plate 9 cannot be reset, the pin 12 remains in the ejection limit state, locking the flat steel conveying and realizing self-inspection of abnormal cutting length.

[0044] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8As shown, the bottom groove 14 has a ramp 15 formed at its end. The inclination angle of the ramp 15 is set to 35°-45°, and the inclination direction of the ramp 15 is consistent with the flat steel conveying direction. When the flat steel is conveyed to the position of the ramp 15, it is out of the magnetization range of the magnetic strip 13, the magnetism fades, and the chips adsorbed at the bottom of the flat steel automatically fall off and slide down the ramp 15 into the chip collection structure inside the cabinet 1, realizing automatic chip collection. The chip collection structure is a drawer-type chip collection box, which is convenient for workers to disassemble and clean.

[0045] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, notch 6 is an open-top structure. The inner frame 7 is vertically slidably assembled with the inner wall of notch 6 via a linear slide rail. A return spring 16 is fixedly installed at the bottom of notch 6. The return spring 16 is a cylindrical helical spring with a spring force greater than the weight of the inner frame 7. When there is no external load, the return spring 16 pushes the inner frame 7 upward, making the top surface of the inner frame 7 flush with the top surface of the track frame 3, ensuring smooth and even flat steel conveying.

[0046] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, an outer frame 17 is fixedly installed on the outer shell of the cutting machine 5. The outer frame 17 is formed by bending steel plate and covers the outside of the blade, serving both protective and linkage transmission functions. The lower end face of the outer frame 17 corresponds to the upper end face of the inner frame 7. When the cutting machine 5 moves downward to cut, the outer frame 17 first contacts the inner frame 7 and presses down on the inner frame 7, so that the top surface of the inner frame 7 is lower than the top surface of the track frame 3, fully exposing the flat steel to be cut, ensuring a flat and unobstructed cut. After cutting, the cutting machine 5 moves upward to reset, the outer frame 17 disengages from the inner frame 7, and the inner frame 7 returns to its original position via the return spring 16.

[0047] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, the inner frame 7 has a sloping groove 18 on its side wall. The opening of the sloping groove 18 is aligned with the top edge of the chip groove 8. The sloping groove 18 has an inclination angle of 40°-45° and is inclined towards the inside of the notch 6. When excessive chips accumulate in the chip groove 8, the chips that exceed the top edge of the groove can be discharged outward along the sloping groove 18. The lower side of the notch 6 has an opening 19 that connects to the chip collection structure of the cabinet 1. The size of the opening 19 matches the discharge end of the sloping groove 18. When the inner frame 7 descends for cutting, the sloping groove 18 and the opening 19 are precisely aligned. Excess chips are guided into the chip collection structure through the sloping groove 18 and the opening 19, which stably controls the amount of chips stored inside the chip groove 8, ensures the accuracy of fixed-length detection, and prevents chips from wrapping around the blade and causing equipment failure.

[0048] A method for using a processing equipment for a steel frame for a school desk includes the following steps:

[0049] S1. Place the flat steel for processing the steel frame of the desk into the slot 4 of the track frame 3, and push the flat steel forward along the slot 4 so that the cutting position of the flat steel moves to the top of the inner frame 7, thus completing the material positioning before cutting.

[0050] S2. Start the cutting machine 5. The cutting machine 5 drives the blade downward. The outer frame 17 first presses down the inner frame 7, causing the inner frame 7 to sink and expose the flat steel to be cut. The blade passes through the notch 6 to complete the cutting of the flat steel.

[0051] The chips generated during cutting fall into the chip groove 8 and accumulate on the surface of the slide plate 9. When the chips accumulate to a preset weight, the slide plate 9 is pressed down and moves downward, compressing the air inside the chip groove 8. The compressed air drives the pin 12 to move upward and push out, locking into the cutting surface of the flat steel to stop and limit the movement of the flat steel.

[0052] S3. After the cutting is completed, the cutting machine 5 moves upward and resets. The inner frame 7 springs back and resets under the action of the reset spring 16, and then continues to push the flat steel forward. When the flat steel passes the magnetic strip 13, it is magnetized and the residual chips inside the chip groove 8 are adsorbed at the bottom.

[0053] When the flat steel moves forward to the preset length, the chips inside the chip groove 8 are completely absorbed and carried away, the load on the slide plate 9 disappears and moves upward to reset under the action of the top spring 10, the air pressure in the groove is restored, the pin 12 falls back, the flat steel limit is released, and the equipment returns to normal feeding state.

[0054] If the forward movement of the flat steel is insufficient, the residual chips in the chip groove 8 will cause the pin 12 to continuously push out, locking the flat steel conveying and indicating an abnormal equipment length.

[0055] S4. When the magnetized flat steel is continuously conveyed to the slope 15 at the end of the bottom groove 14, it is separated from the magnetization area of ​​the magnetic strip 13 and the magnetism is deactivated. The chips adsorbed at the bottom of the flat steel automatically fall off and slide down the slope 15 into the chip collection structure.

[0056] Meanwhile, excessive chips accumulated inside the chip groove 8 can be guided into the chip collection structure through the inclined groove 18 and the through-hole 19 to continuously maintain the cleanliness inside the equipment and complete a single cutting cycle. Repeating the above steps can achieve continuous cutting operations.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
