A rod cutting machine for fastener production

Abstract

The present invention relates to the technical field of fastener production, and specifically to a rod cutting machine for fastener production, comprising: a machine platform; a protective cover fixedly mounted on the machine platform; and a cooling mechanism for cooling the rods during cutting. In the present invention, a nozzle can spray coolant onto the cutting disc and the rod cutting area from both sides of the cutting disc at the same time, resulting in a better cooling effect. By setting up a protective box, the cutting area can be covered, reducing the cutting area and, to a certain extent, reducing the range in which the high-speed rotating cutting disc throws out the coolant and waste chips generated by cutting. This not only prevents the coolant from being mixed with waste chips and being thrown onto the machine platform and the inner wall of the protective cover over a large area by the centrifugal force of the cutting disc, causing cleaning difficulties, but also ensures that the coolant can quickly flow back to the cooling box, ensuring the circulation process of the coolant.

Description

Technical Field

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

[0002] Fasteners are a general term for a type of mechanical parts used to fasten two or more parts (or components) into a whole. They are widely used in many fields such as machinery, equipment, vehicles, ships, railways, bridges, and construction. When producing fasteners, a cutting machine is required to cut the rods into different lengths.

[0003] A Chinese patent application numbered CN202222713384.4 discloses a stainless steel rod cutting machine, which belongs to the field of cutting machines and includes a cutting platform. The cutting platform is provided with a cutting machine body on the upper portion thereof. A saw blade slot is provided on the upper surface of the cutting platform. A chip wiping assembly is provided on one side of the saw blade slot. The chip wiping assembly 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 a chip wiping bristle is provided on the inner arc surface of the chip wiping rubber sleeve. Through the chip wiping assembly, during the process of the stainless steel rod passing through and out of the chip wiping rubber sleeve, the chip wiping bristles evenly arranged on the inner wall of the chip wiping rubber sleeve can wipe away waste chips attached to the surface of the stainless steel rod. Through the provided bundling device, the stainless steel short rod pushed out from the positioning sleeve falls into the steel rod receiving chamber of the steel rod receiving frame. The bundling strap is preset inside the steel rod receiving frame, so that the stainless steel short rods can be concentrated above the bundling strap, providing convenience for subsequent rapid bundling.

[0004] When existing cutting devices cut rods, they need 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 waste chips generated by cutting. 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 difficulty of cleaning.

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

[0006] The object of the present invention is to provide a rod cutting machine for fastener production that can effectively solve the above technical problems.

[0007] In order to achieve the purpose of the present invention, the following technical solutions are adopted:

[0042] like Figures 1 to 10 As shown, the present invention is a rod cutting machine for fastener production, comprising: a machine platform 1; a protective cover 2 fixedly mounted on the machine platform 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.

[0043] The cooling mechanism 5 includes: a cooling box 51 fixedly installed in the machine 1, a partition fixedly installed in the cooling box 51, and the cooling box 51 can be divided into two independent spaces by the partition, the space at the top of the partition is used to store 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 1; a pump body 53 fixedly installed in the cooling box 51; a collecting pipe 54 fixedly installed in the protective box 52, two collecting pipes 54 are provided, and are symmetrically arranged in the protective box 52; a nozzle 55 connected to the collecting pipe 54, a plurality of nozzles 55 are provided, and the liquid outlet end of the nozzle 55 points to the cutting point of the rod; a filtering component 57 for filtering the coolant; and a switching component 56 for switching the flow direction of the coolant.

[0044] The cooling box 51 is connected to the protective box 52. A cutting opening is provided on the protective box 52. Circular openings are symmetrically provided on the side walls of the protective box 52. When cutting the rod, the rod is passed through the two circular openings and fixed by the fixing mechanism 4 to prevent the rod from being displaced during cutting, thereby affecting the cutting accuracy.

[0045] The liquid inlet end of the pump body 53 is installed with a liquid inlet pipe, and the liquid inlet pipe is plugged and installed on the partition. The liquid outlet end of the pump body 53 is connected to the switching component 56 through the liquid outlet pipe.

[0046] 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 that drives the sliding block 562 to return to its original position, one end of the linkage spring 563 is fixedly connected to the sliding block 562, and the other end of the linkage spring 563 is 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 passes through the side wall of the fixed shell 561, and the linkage block 564 is close to the sliding block 562. 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 to the liquid collecting chamber 565, and the liquid guiding chamber 1 566 matches the liquid guiding hole 1 568, and the liquid guiding chamber 2 567 matches the liquid guiding hole 2 569.

[0047] The liquid outlet end of the liquid outlet pipe is communicated with the liquid collecting chamber 565 .

[0048] Liquid guide hole 1 568 is connected to liquid guide tube 1, liquid guide hole 2 569 is connected to liquid guide tube 2, and liquid guide tube 2 is connected to both liquid collecting tubes 54.

[0049] In the initial state, that is, when the rod is not cut, the first liquid guide cavity 566 is completely aligned with the first liquid guide hole 568, and the second liquid guide cavity 567 is completely staggered with the second liquid guide hole 569.

[0050] As attached Figure 3 As shown, when one end of the rod passes through the two circular openings from left to right, it can abut and squeeze the arcuate side of the linkage block 564, thereby driving the linkage block 564 to move into the fixed shell 561. 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.

[0051] 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 wrapping around the cutting disk 32 or clogging the cutting area.

[0052] Since there are two collecting pipes 54 and they are symmetrically arranged in the protective 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 part of the rod from both sides at the same time, which has a better cooling effect.

[0053] 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 disc 32 that throws out the coolant and waste chips generated by cutting is reduced to a certain extent. It not only prevents the coolant mixed with waste chips from being thrown onto the inner wall of the protective cover 2 in a large range by the centrifugal force of the cutting disc 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.

[0054] It should be noted that in the present invention, when the rod is cut, the rod with the smallest diameter cut from left to right passes through the two circular openings, which can abut and squeeze the curved side of the linkage block 564, thereby driving the linkage block 564 to move into the fixed housing 561. The linkage block 564 drives the sliding block 562 to move downward, and the first liquid guide cavity 566 and the first liquid guide hole 568 are completely offset, and the second liquid guide cavity 567 and the second liquid guide hole 569 are connected.

[0055] As 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 greater, the connecting portion between the second liquid guide cavity 567 and the second liquid guide hole 569 becomes larger, and the amount of cooling entering the collecting pipe 54 increases, thereby increasing the amount of coolant ejected from the nozzle 1 55. As the diameter of the rod increases, more cutting heat and friction heat are generated during cutting, and a larger coolant flow rate is required to effectively take away the heat, thereby preventing the cutting disc 32 from overheating and material performance degradation.

[0056] 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 to the filter screen 572 and the partition; a turbine 578 fixedly installed on the rotating rod 574; a rotating plate 575 fixedly mounted on the rotating rod 574; the electromagnet 571 is ring-shaped, and the interior of the electromagnet 571 is arc-shaped; the rotating plate 575 is petal-shaped, and the top of the rotating plate 575 is arc-shaped.

[0057] While the rod is being cut, the electromagnet 571 is energized, causing the electromagnet 571 to generate magnetism. In the present invention, the rod being cut is made of iron, and the cutting waste is iron chips, which can be adsorbed by the electromagnet 571 .

[0058] 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, which can guide the coolant, 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. The waste chips in the coolant can be adsorbed by the electromagnet 571, thereby filtering the coolant.

[0059] By setting the curved 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 concentratedly to the middle part of the filter screen 1 572, which is convenient for the subsequent cleaning unit 2 577 to collect waste chips.

[0060] The coolant filtered by the electromagnet 571 is filtered again by the filter 572 and flows to the top of the partition, thereby achieving double filtration of the coolant and improving the filtering effect of the coolant.

[0061] 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 2 5762 hingedly installed on the annular tube 5761, and a plurality of nozzles 2 5762 are provided, and the plurality of nozzles 2 5762 are evenly distributed along the circumference of the annular tube 5761; a reset spring 5763 for driving the nozzle 2 5762 to reset, one end of the reset spring 5763 is fixedly connected to the nozzle 2 5762, and the other end of the reset spring 5763 is fixedly connected to the annular tube 5761; the annular tube 5761 and the nozzle 2 5762 are connected through a liquid guide tube 3.

[0062] When the rod is cut, it is removed from the circular opening. At this time, the rod no longer has an extrusion 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 staggered with the liquid guide hole 2 569.

[0063] At the same time, the electromagnet 571 is powered off, and the electromagnet 571 has no magnetism and cannot absorb the waste chips.

[0064] At this time, the coolant transported by the pump body 53 to the liquid collecting chamber 565 enters the annular tube 5761 through the liquid guide chamber 1 566, the liquid guide hole 1 568, and the liquid guide tube 1, and is sprayed out through the plurality of nozzles 2 5762. The coolant is sprayed on the curved surface of the electromagnet 571. By spraying the coolant on the curved surface of the electromagnet 571, the waste chips adsorbed on the curved surface of the electromagnet 571 are washed away, thereby cleaning the curved surface of the electromagnet 571.

[0065] At the same time, the rotation of the rotating plate 575 drives the second nozzle 5762 to move along its petal-shaped edge, and cooperates with the elastic force of the reset spring 5763 to make multiple second nozzles 5762 synchronously retract inward or expand outward, that is, the swing of the second nozzle 5762 is realized, thereby expanding the spraying range of the second nozzle 5762, so that the curved surface of the electromagnet 571 can be fully flushed, thereby improving the cleaning effect of the electromagnet 571 and preparing for subsequent use.

[0066] The filter assembly 57 also includes: a cleaning unit 2 577 for cleaning the filter screen; the cleaning unit 2 577 includes: a collection pipe 5774, a plurality of collection pipes 5774 are provided, and the plurality of collection pipes 5774 are evenly distributed along the circumference of the rotating rod 574; a scraper 5775 fixedly mounted on the collection pipe 5774, a guide plate 5776, and a second filter screen 5777, the bottom of the scraper 5775 abuts against the first filter screen 572, two guide plates 5776 are provided, and the second filter screen 577 7 is located at the bottom of the collection pipe 5774. The collection pipe 5774 is provided with a collection opening 1 and a collection opening 2. The collection opening 1 is located between the two guide plates 5776, and the collection opening 2 is located at the top of the scraper 5775. A connecting shell 5771 is fixedly installed on the rotating rod 574, and a positioning rod 5773 is fixedly installed in the connecting shell 5771. A connecting block 5772 is fixedly installed at the end of the collection pipe 5774, and a positioning hole matching the positioning rod 5773 is opened on the connecting block 5772.

[0067] Under normal conditions, that is, when the filter 572 is to be cleaned, 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 tube 5774 to rotate. At this time, the scraper 5775 can scrape up the waste on the top of the filter 572, and allow the waste to enter the collecting tube 5774 through the collecting opening 2 along the top of the scraper 5775 for collection. The coolant mixed in the waste is filtered out through the filter 2 5777, thereby realizing the cleaning of the filter 572 and ensuring the filtering effect of the filter 572.

[0068] In addition, when the waste chips on the curved surface of the electromagnet 571 are washed away, the waste chips mixed with the coolant flow to the filter 572. At this time, the wash-off waste chips and coolant can be collected through the cooperation of the guide plate 5776 on the collection pipe 5774 and the collection opening 1, thereby reducing the waste chips falling on the top of the filter 572 and improving the cleaning efficiency of the filter 572.

[0069] When a certain amount of waste chips are collected in the collection pipe 5774, a sealing door is installed on the side wall of the cooling box 51 near the collection pipe 5774. At this time, the sealing door is opened and the connecting block 5772 is pulled upward 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 box 51, and the waste chips in the collection pipe 5774 can be cleaned. At this time, the sealing door is closed, and the coolant can continue to be filtered through the filter net 572. After cleaning, the collection pipe 5774 can be restored to its normal state.

[0070] From the above, it can be seen that the provision of the cleaning unit 2 577 facilitates the cleaning of the filter 1 572 without the need to disassemble the filter 1 572 and without the need to shut down the machine for a long time for cleaning, thereby improving the convenience of using the cutting machine.

[0071] The stirring blade 58 is fixedly mounted on the rotating rod 574 .

[0072] The cooling box 51 is externally connected to a refrigeration unit, so that the coolant can be cooled, thereby ensuring the cooling effect of the coolant.

[0073] When the rotating rod 574 rotates, it can drive the stirring blade 58 to rotate, thereby stirring the coolant, so that the coolant is cooled evenly, thereby further ensuring the cooling effect of the coolant.

[0074] The cutting mechanism 3 includes: a power source 1 33 fixedly mounted on the protective cover 2; a mounting base 34 fixedly mounted on the movable end of the power source 1 33; a power source 2 31 fixedly mounted on the mounting base 34; and a cutting disc 32 fixedly mounted on the output shaft of the power source 2 31.

[0075] When cutting the rod, start power source 2 31 to drive the cutting disc 32 to rotate, and start power source 1 33 to drive the mounting base 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, thereby achieving cutting of the rod.

[0076] It should be added that the power source 1 33 is preferably a telescopic cylinder; the power source 2 31 is preferably a motor.

[0077] The fixing mechanism 4 includes: a guide rod 42 fixedly mounted on the machine 1; a sliding frame 41 slidably mounted on the guide rod 42; a power source 3 43 for driving the sliding frame 41 to move; a clamping assembly 44 mounted on the sliding frame 41; a rotating assembly 45 for driving the clamping assembly 44 to rotate; the rotating assembly 45 includes: a power source 5 451 fixedly mounted on the sliding frame 41; a connecting member 452 for linking the power source 5 451 with the rotating drum 441; the clamping assembly 44 includes: a rotating drum 441 rotatably mounted on the sliding frame 41; a fixing bar 442 fixedly mounted on the rotating drum 441; a guide groove 443 provided on the fixing bar 442; and a setting There are two rotating frames 444 in the rotating drum 441, and they are symmetrically arranged in the rotating drum 441; there are multiple guide grooves 445 opened on the rotating frame 444; there are multiple connecting rods 446 fixedly installed on the rotating frame 444, and both ends of the multiple connecting rods 446 are fixedly connected to the adjacent rotating frames 444; there are multiple clamping rods 447 slidably installed in the guide grooves 443 and the guide grooves 445; there are multiple clamping rods 447; there is a power source four 448 hingedly installed in the rotating drum 441; the movable end of the power source four 448 is rotatably connected to the connecting rod 446.

[0078] In the present invention, two groups of fixing mechanisms 4 are provided, and are symmetrically arranged on both sides of the protection box 52 .

[0079] When fixing the rod, one end of the rod is passed through the two sets of fixing mechanisms 4 and the two circular openings from left to right in sequence.

[0080] At this time, the power source 448 is started to extend and drive the connecting rod 446 to move, and the connecting rod 446 drives the two rotating frames 444 to rotate. Driven by the guide 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 are close to each other and pressed against the rod, thereby achieving clamping and fixing of the rod.

[0081] Since the multiple clamping rods 447 clamp and fix the rod from different directions, the clamping stability of the rod is improved, displacement during cutting is avoided, and cutting accuracy is guaranteed.

[0082] The multiple clamping rods 447 can be synchronously moved closer to or farther away from each other, thereby clamping and fixing rods of different diameters, thereby improving the adaptability of the cutting machine.

[0083] When the length of the rod is short, the power source 3 43 is started to drive the sliding frame 41 to move axially along the guide rod 42, and the sliding frame 41 is close to the protective box 52, so that the clamping assembly 44 is close to the protective box 52, thereby realizing the adjustment of the distance between the two sets of fixing mechanisms 4, thereby facilitating the clamping and fixing of rods of different lengths, further improving the adaptability of the cutting machine.

[0084] In addition, when the diameter of the rod is large and the cutting disk 32 cannot be cut from top to bottom at one time, the cutting disk 32 is now cut downward beyond the radius of the rod, and the two power sources 451 are started at the same time to drive the adjacent connecting parts 452 to rotate, and the connecting parts 452 drive the rotating drum 441 to rotate, thereby driving the rod to rotate. When the rod rotates one circle, the cutting disk 32 completes the cutting, which makes it easier for the cutting disk 32 to cut rods of different diameters, further improving the adaptability of the cutting machine.

[0085] It is added here that power source three 43 and power source four 448 are preferably telescopic cylinders; power source five 451 is preferably a motor; and the connecting member 452 is preferably a belt, a pulley or a chain, a sprocket; for example, when using a belt or a pulley, two pulleys, one of which is fixedly mounted on the output end of power source four 448, and the other pulley is fixedly mounted on the rotating drum 441, and the two pulleys are driven by a belt, and there is at least one belt.
