Description

Technical Field

[0001] The present invention relates to the technical field of fastener production, and particularly relates to a bar cutting machine for fastener production. Background Art

[0002] Fasteners are a general term for a class of mechanical parts used to firmly connect two or more parts (or components) into a whole, and are widely used in many fields such as machinery, equipment, vehicles, ships, railways, bridges, and buildings. When producing fasteners, a cutting machine is needed to cut bars into different lengths.

[0003] A Chinese patent with the application number CN202222713384.4 discloses a stainless steel bar cutting machine, belonging to the field of cutting machines, including a cutting platform. A cutting machine body is arranged on the upper part of the cutting platform. A saw blade through groove is opened on the upper surface of the cutting platform. A chip wiping component is arranged on one side surface of the cutting platform at one side of the saw blade through groove. The chip wiping component includes a positioning sleeve, a chip wiping rubber sleeve, and chip wiping bristles. A chip wiping rubber sleeve is fixedly installed inside the positioning sleeve, and chip wiping bristles are arranged on the inner arc surface of the chip wiping rubber sleeve. Through the arranged chip wiping component, during the process of the stainless steel bar passing through and out of the chip wiping rubber sleeve, the chip wiping bristles uniformly arranged on the inner wall of the chip wiping rubber sleeve can wipe off the waste chips adhered to the surface of the stainless steel bar. Through the arranged bundling device, the cut stainless steel short bars pushed out from the positioning sleeve fall into the steel bar receiving chamber of the steel bar receiving frame. The bundling straps are preset inside the steel bar receiving frame, so that the stainless steel short bars can be concentrated above the bundling straps, facilitating subsequent rapid bundling.

[0004] When the existing cutting device cuts a bar, it is necessary to spray coolant to reduce the temperature of the cutting area to protect the equipment and materials. The high-speed rotating cutter head not only generates a large amount of heat, but also throws out the coolant and the waste chips generated by cutting together. The waste chips are thrown onto the inner wall of the equipment along with the coolant, which not only affects the cleanliness of the equipment, but also increases the cleaning difficulty.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above defects. Summary of the Invention

A connecting shell is fixedly installed on the rotating rod, a positioning rod is fixedly installed inside the connecting shell, a connecting block is fixedly installed at the end of the collecting pipe, and a positioning hole matching the positioning rod is formed on the connecting block.

[0012] Furthermore, the cooling mechanism further includes: a switching component for switching the flow direction of the coolant.

[0023] As Figures 1 to 10 shown, a rod cutting machine for fastener production according to the present invention includes: a machine table 1; a protective cover 2 fixedly installed on the machine table 1; a fixing mechanism 4 for fixing the rod; a cutting mechanism 3 for cutting the rod; and a cooling mechanism 5 for cooling the rod during cutting.

[0024] The cooling mechanism 5 includes: a cooling tank 51 fixedly installed in the machine table 1, a partition is fixedly installed in the cooling tank 51, and the cooling tank 51 can be divided into two independent spaces by the partition. The space at the top of the partition is used to store the coolant, and the space at the bottom of the partition is used to install other equipment; a protective box 52 fixedly installed on the machine table 1; a pump body 53 fixedly installed in the cooling tank 51; a liquid collecting pipe 54 fixedly installed in the protective box 52, there are two liquid collecting pipes 54, and they are symmetrically arranged in the protective box 52; a first spray head 55 communicated with the liquid collecting pipe 54, there are several first spray heads 55, and the liquid outlet end of the first spray head 55 points to the cutting place of the rod; a filtering component 57 for filtering the coolant; and a switching component 56 for switching the flow direction of the coolant.

[0025] The cooling tank 51 is communicated with the protective box 52, a cutting opening is provided on the protective box 52, and circular openings are symmetrically provided on the side wall of the protective box 52. When cutting the rod, the rod passes through the two circular openings, and the rod is fixed by the fixing mechanism 4 to prevent the rod from shifting during cutting and affecting the cutting accuracy.

[0026] The liquid inlet end of the pump body 53 is installed with a liquid inlet pipe, and the liquid inlet pipe is inserted and installed on the partition, and the liquid outlet end of the pump body 53 is communicated with the switching component 56 through a liquid outlet pipe.

[0027] The switching assembly 56 includes: a fixed shell 561 fixedly mounted on the protective box 52; a sliding block 562 slidably mounted in the fixed shell 561; a linkage spring 563 for driving the sliding block 562 to return to its original position, one end of the linkage spring 563 being fixedly connected to the sliding block 562, and the other end of the linkage spring 563 being fixedly connected to the inner wall of the fixed shell 561; a linkage block 564 fixedly mounted on the sliding block 562, the top of the linkage block 564 passing through the side wall of the fixed shell 561, and the linkage block 564 being close to the inner wall of the fixed shell 561. One side of the protective box 52 is arranged in an arc shape; a liquid collecting chamber 565, a liquid guiding chamber 1 566, and a liquid guiding chamber 2 567 are provided on the sliding block 562; a liquid guiding hole 1 568 and a liquid guiding hole 2 569 are provided on the fixed shell 561; the liquid guiding hole 1 568 is a round hole, and the liquid guiding hole 2 569 is a waist hole, and the liquid guiding chamber 1 566 and the liquid guiding chamber 2 567 are both connected with the liquid collecting chamber 565, and the liquid guiding chamber 1 566 matches with the liquid guiding hole 1 568, and the liquid guiding chamber 2 567 matches with the liquid guiding hole 2 569.

[0028] The liquid outlet end of the liquid outlet pipe is communicated with the liquid collecting chamber 565 .

[0029] Liquid guiding hole 1 568 is connected to liquid guiding tube 1, liquid guiding hole 2 569 is connected to liquid guiding tube 2, and liquid guiding tube 2 is connected to both liquid collecting tubes 54 .

[0030] In the initial state, that is, when the rod is not cut, the first liquid guiding cavity 566 is completely aligned with the first liquid guiding hole 568, and the second liquid guiding cavity 567 is completely offset from the second liquid guiding hole 569.

[0031] As attached Figure 3 As shown, when one end of the rod passes through the two circular openings from left to right, the arc-shaped side of the linkage block 564 can be abutted and squeezed, thereby driving the linkage block 564 to move into the fixed shell 561, and the linkage block 564 drives the sliding block 562 to move downward and drives the linkage spring 563 to be compressed, so that the liquid guide cavity 1 566 and the liquid guide hole 1 568 are completely offset, and the liquid guide cavity 2 567 and the liquid guide hole 2 569 have a connecting part.

[0032] When the rod is fixed, the cutting mechanism 3 is started to cut the rod. At the same time, the pump body 53 is started to suck out the coolant and transport it to the liquid collecting chamber 565 through the liquid outlet pipe. At this time, the liquid guide chamber 1 566 and the liquid guide hole 1 568 are completely staggered, and the liquid guide chamber 2 567 and the liquid guide hole 2 569 are connected. The coolant enters the liquid collecting pipe 54 through the liquid guide chamber 2 567, the liquid guide hole 2 569, and the liquid guide pipe 2, and is sprayed on the cutting part of the rod through the nozzle 1 55. On the one hand, the cutting disk 32 and the rod can be cooled to avoid the friction between the cutting disk 32 and the rod to generate a lot of heat, which affects the cutting accuracy. On the other hand, the coolant can discharge the waste chips generated during cutting to avoid the waste chips from entangled with the cutting disk 32 or blocking the cutting area.

[0033] Since there are two collecting pipes 54 and they are symmetrically arranged in the protection box 52, when cutting, the cutting disc 32 is located between the two collecting pipes 54, so that the nozzle 1 55 can spray coolant to the cutting disc 32 and the cutting position of the rod from both sides at the same time, and the cooling effect is better.

[0034] By setting up the protective box 52, the cutting area can be covered, the cutting area is reduced, and the range of the high-speed rotating cutting disk 32 that throws out the coolant and the waste chips generated by cutting is reduced to a certain extent. It not only prevents the coolant mixed with the waste chips from being thrown onto the inner wall of the protective cover 2 in a large range due to the centrifugal force of the cutting disk 32, causing cleaning difficulties, but also ensures that the coolant can quickly flow back to the cooling box 51, ensuring the circulation process of the coolant.

[0035] It is to be added that, in the present invention, when the rod is cut, when the rod with the smallest diameter cut passes through the two circular openings from left to right, the arc-shaped side of the linkage block 564 can be abutted and squeezed, thereby driving the linkage block 564 to move into the fixed shell 561, and the linkage block 564 drives the sliding block 562 to move downward, so that the first liquid guide cavity 566 and the first liquid guide hole 568 are completely staggered, and the second liquid guide cavity 567 and the second liquid guide hole 569 have a connecting part; When the diameter of the rod being cut gradually increases, the distance that the linkage block 564 drives the sliding block 562 to move downward becomes larger, the connecting part between the liquid guide cavity 567 and the liquid guide hole 569 becomes larger, and the cooling amount entering the collecting pipe 54 increases, so that the spraying amount of the coolant from the nozzle 55 increases. Since the larger the diameter of the rod, the more cutting heat and friction heat are generated during cutting, a larger coolant flow rate is needed to effectively take away the heat, thereby preventing the cutting disk 32 from overheating and material performance degradation.

[0036] The filter assembly 57 includes: an electromagnet 571 and a filter screen 572 fixedly installed in the cooling box 51; a liquid collecting shell 573 fixedly installed in the cooling box 51, and the liquid collecting shell 573 is connected to the liquid outlet pipe; a rotating rod 574 rotatably installed on the liquid collecting shell 573, and the rotating rod 574 is rotatably connected with the filter screen 572 and the partition; a turbine 578 fixedly installed on the rotating rod 574; a rotating plate 575 fixedly sleeved on the rotating rod 574; the electromagnet 571 is ring-shaped, and the interior of the electromagnet 571 is arranged in an arc shape; the rotating plate 575 is petal-shaped, and the top of the rotating plate 575 is arranged in an arc shape.

[0037] While the rod is being cut, the electromagnet 571 is energized to generate magnetism. The rod to be cut in the present invention is made of iron, and the cutting waste is iron filings, which can be adsorbed by the electromagnet 571 .

[0038] When the rod is cut, the pump body 53 is started to deliver the coolant, and the flow of the coolant can drive the turbine 578 to rotate, the turbine 578 drives the rotating rod 574 to rotate, and the rotating rod 574 drives the rotating plate 575 to rotate. When the coolant enters the cooling box 51, it first contacts the top of the rotating plate 575. The top of the rotating plate 575 is arranged in an arc shape, so that the coolant can be guided, so that the coolant flows from the center of the top of the rotating plate 575 to the edge, and through the rotation of the rotating plate 575, the coolant is sprinkled onto the arc surface of the electromagnet 571 by the action of centrifugal force, and the waste chips in the coolant can be adsorbed by the electromagnet 571, thereby filtering the coolant.

[0039] By setting the arc surface of the electromagnet 571, on the one hand, the adsorption area of ​​the electromagnet 571 in the coolant is expanded, thereby improving the filtering effect of the coolant; on the other hand, it plays a role in guiding the coolant, so that the coolant flows to the middle part of the filter screen 572, which is convenient for the subsequent cleaning unit 2 577 to collect waste chips.

[0040] The coolant filtered by the electromagnet 571 is filtered again by the filter screen 572 and flows to the top of the partition, thereby realizing double filtering of the coolant and improving the filtering effect of the coolant.

[0041] The filter assembly 57 also includes: a cleaning unit 576 for cleaning the electromagnet 571; the cleaning unit 576 includes: an annular tube 5761 fixedly installed in the cooling box 51; a nozzle 5762 hingedly installed on the annular tube 5761, a plurality of nozzles 5762 are provided, and the plurality of nozzles 5762 are evenly distributed along the circumference of the annular tube 5761; a reset spring 5763 for driving the nozzle 5762 to reset, one end of the reset spring 5763 is fixedly connected to the nozzle 5762, and the other end of the reset spring 5763 is fixedly connected to the annular tube 5761; the annular tube 5761 is connected to the nozzle 5762 through a liquid guide tube 3.

[0042] When the rod is cut, it is taken out from the circular opening. At this time, the rod has no squeezing effect on the linkage block 564. The elastic force of the linkage spring 563 can drive the sliding block 562 to return to its initial state, that is, the liquid guide cavity 1 566 is completely aligned with the liquid guide hole 1 568, and the liquid guide cavity 2 567 is completely offset from the liquid guide hole 2 569.

[0043] At the same time, the electromagnet 571 is powered off, and the electromagnet 571 has no magnetism and cannot absorb the waste chips.

[0044] At this time, the coolant transported by the pump body 53 into the liquid collection cavity 565 enters the annular pipe 5761 through the first liquid guide cavity 566, the first liquid guide hole 568, and the first liquid guide pipe, and is ejected through a plurality of second nozzles 5762. The coolant is sprayed on the arc surface of the electromagnet 571. Through the spraying of the coolant on the arc surface of the electromagnet 571, the waste chips adsorbed on the arc surface of the electromagnet 571 are washed and dropped, thus playing a role in cleaning the arc surface of the electromagnet 571.

[0045] At the same time, the rotating plate 575 rotates to drive the second nozzles 5762 to move along the petal-shaped edge thereof, and with the elastic force of the return spring 5763, a plurality of second nozzles 5762 are synchronously closed inward or expanded outward, that is, the swinging of the second nozzles 5762 is realized, thereby expanding the spraying range of the second nozzles 5762, so that the arc surface of the electromagnet 571 can be comprehensively washed, improving the cleaning effect of the electromagnet 571 and preparing for subsequent use.

[0046] The filtering assembly 57 further includes: a second cleaning unit 577 for cleaning the first filter screen 572; the second cleaning unit 577 includes: a plurality of collecting pipes 5774, which are arranged along the circumferential direction of the rotating rod 574; a scraper 5775, a diversion plate 5776, and a second filter screen 5777 fixedly installed on the collecting pipe 5774. The bottom of the scraper 5775 abuts against the first filter screen 572. Two diversion plates 5776 are provided. The second filter screen 5777 is located at the bottom of the collecting pipe 5774. The collecting pipe 5774 is provided with a first collecting opening and a second collecting opening. The first collecting opening is located between the two diversion plates 5776, and the second collecting opening is located at the top of the scraper 5775; a connecting shell 5771 is fixedly installed on the rotating rod 574, a positioning rod 5773 is fixedly installed in the connecting shell 5771, and an end of the collecting pipe 5774 is fixedly installed with a connecting block 5772, and the connecting block 5772 is provided with a positioning hole matching the positioning rod 5773.

[0047] Under normal conditions, that is, when cleaning the first filter screen 572, the connecting block 5772 is inserted into the connecting shell 5771, and the positioning rod 5773 is inserted into the positioning hole. At this time, when the rotating rod 574 rotates, it can drive the connecting shell 5771 to rotate, thereby driving the collecting pipe 5774 to rotate. At this time, the scraper 5775 can scrape up the waste chips on the top of the first filter screen 572, and the waste chips can enter the collecting pipe 5774 through the second collecting opening along the top of the scraper 5775 for collection. The coolant mixed in the waste chips is filtered out through the second filter screen 5777, thus realizing the cleaning of the first filter screen 572 and ensuring the filtering effect of the first filter screen 572.

[0048] In addition, when the waste chips on the arc surface of the electromagnet 571 are washed away, the waste chips mixed with the coolant flow towards the first filter screen 572. At this time, through the cooperation of the guide plate 5776 on the collection pipe 5774 and the first collection opening, the washed waste chips and coolant can be collected, thereby reducing the waste chips from falling on the top of the first filter screen 572 and improving the cleaning efficiency of the first filter screen 572.

[0049] When a certain amount of waste chips are collected in the collection pipe 5774, a sealing door is installed at a position on the side wall of the cooling tank 51 close to the collection pipe 5774. At this time, open the sealing door and pull up the connecting block 5772 to separate the connecting block 5772 from the connecting shell 5771. At this time, the collection pipe 5774 can be disassembled, so that the collection pipe 5774 can be taken out of the cooling tank 51, and then the waste chips in the collection pipe 5774 can be cleaned. At this time, close the sealing door, and the filtration of the coolant can continue through the first filter screen 572. After the cleaning is completed, restore the collection pipe 5774 to its normal state.

[0050] As can be seen from the above, through the setting of the second cleaning unit 577, it is convenient to clean the first filter screen 572 without disassembling the first filter screen 572 and without long-term shutdown for cleaning, thereby improving the convenience of using the cutting machine.

[0051] A stirring blade 58 is fixedly installed on the rotating rod 574.

[0052] The cooling tank 51 is externally connected with a refrigeration unit, so as to refrigerate the coolant and ensure the refrigeration effect of the coolant.

[0053] When the rotating rod 574 rotates, it can drive the stirring blade 58 to rotate, so as to stir the coolant and make the coolant cool evenly, thereby further ensuring the refrigeration effect of the coolant.

[0055] When cutting a rod, start the second power source 31 to drive the cutting disc 32 to rotate, and start the first power source 33 to drive the mounting seat 34 to move downward, thereby driving the cutting disc 32 to move downward. The cutting disc 32 passes through the cutting opening and enters the protective box 52, and then the cutting of the rod is realized.

[0056] It should be added here that the first power source 33 is preferably a telescopic cylinder; the second power source 31 is preferably a motor.

[0058] In the present invention, two sets of fixing mechanisms 4 are provided and symmetrically arranged on both sides of the protection box 52.

[0059] When fixing the rod member, one end of the rod member is sequentially passed through the two circular openings in the two sets of fixing mechanisms 4 from left to right.

[0060] At this time, start the fourth power source 448 to extend and drive the linkage rod 446 to move. The linkage rod 446 drives the two rotating frames 444 to rotate. Driven by the guiding groove 445, the clamping rod 447 can be driven to move along the path of the guide groove 443, so that the multiple clamping rods 447 approach each other and tightly press against the rod member, thereby realizing the clamping and fixing of the rod member.

[0061] Since the multiple clamping rods 447 clamp and fix the rod member from different directions, the clamping stability of the rod member is improved, displacement during cutting is avoided, and the cutting accuracy is guaranteed.

[0062] The multiple clamping rods 447 can approach or move away from each other synchronously, so that rod members with different diameters can be clamped and fixed, improving the adaptability of the cutting machine.

[0063] When the length of the rod member is short, start the third power source 43 to drive the sliding frame 41 to move axially along the guide rod 42, and make the sliding frame 41 approach the protection box 52, so that the clamping assembly 44 approaches the protection box 52, thereby realizing the adjustment of the distance between the two sets of fixing mechanisms 4, facilitating the clamping and fixing of rod members with different lengths, and further improving the adaptability of the cutting machine.

[0064] In addition, when the diameter of the rod is large, resulting in the cutting disc 32 being unable to cut through the rod from top to bottom in one go, first cut the cutting disc 32 downward beyond the radius of the rod, and at the same time start two power sources five 451 to drive the adjacent linkage 452 to rotate. The linkage 452 drives the rotating cylinder 441 to rotate, thereby driving the rod to rotate. When the rod rotates one week, the cutting disc 32 completes the cutting, which makes it convenient for the cutting disc 32 to cut rods with different diameters, further improving the adaptability of the cutting machine.

[0065] It should be added here that the power source three 43 and the power source four 448 are both preferably telescopic cylinders; the power source five 451 is preferably a motor; the linkage 452 is preferably a belt, a pulley or a chain, a sprocket; for example, when using a belt and a pulley, two pulleys, one of which is fixedly installed at the output end of the power source four 448, and the other is fixedly installed on the rotating cylinder 441. The two pulleys are driven by a belt, and there is at least one belt.
