Description

Technical Field

[0001] This invention relates to the field of cold heading machine technology, specifically to an environmentally friendly and intelligent cold heading forming machine. Background Technology

[0002] Cold heading machines are commonly used in the fastener industry. They are specialized equipment used for the mass production of fasteners such as nuts and bolts, with the main function of upsetting. Cold heading is a forging method that uses a die to upset metal bars at room temperature. During the processing, the cold heading machine needs to use lubricating oil to lubricate the mechanical parts, reduce friction and wear, and ensure the machine's working efficiency and lifespan. In addition, the cold heading machine generates heat during operation, which needs to be dissipated through cooling water to prevent the machine from overheating and being damaged.

[0003] Current cold heading machines require a constant supply of coolant to dissipate heat during operation. This necessitates a continuous circulation of coolant and the addition of lubricating oil to protect the equipment. If the coolant and lubricating oil mix together after use and cannot be recycled, it leads to high energy consumption and is not environmentally friendly.

[0004] To address this, China Patent Network published an energy-saving cold heading machine with publication number CN213670827U. The machine includes a main body with a base plate fixedly connected to its bottom. A cleaning box is located on one side of the top of the base plate, and a horizontal pipe is fixedly embedded on one side of the top of the cleaning box. Multiple heat-conducting pipes are fixedly connected to one side wall of the horizontal pipe. A heating plate is fixedly installed on one side of the top of the base plate. By using multiple heat-conducting pipes on one side of the top of the cleaning box, along with the heating box, extraction pipe, and connecting pipe, the lubricating oil floating on the water surface during cleaning can be extracted, allowing the remaining water to be used for multiple cleaning cycles. Simultaneously, the extracted lubricating oil is heated to remove water, thus obtaining pure lubricating oil that can be reused, making it more environmentally friendly and energy-efficient.

[0005] The aforementioned public documents state that although the lubricating oil in the coolant can be separated and recycled, additional energy-consuming equipment is required to clean and separate the workpieces when separating the mixed liquids. This indirectly increases the energy consumption of the equipment during processing, resulting in high energy consumption and making it neither energy-efficient nor environmentally friendly. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an environmentally friendly intelligent cold heading forming machine, which can effectively solve the problems of inconvenience in separating and recycling the mixed liquid after cold heading processing in the existing technology, and the energy consumption of separation and recycling.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides an environmentally friendly intelligent cold heading forming machine, including a cold heading machine body and a circulating liquid spraying assembly disposed thereon, and further comprising:

[0009] The discharge assembly is used to collect workpieces and rotate them out when they reach a certain weight. The discharge assembly includes a loading plate rotatably connected to the main body of the cold heading machine and a counterweight block set on the loading plate. The rotation shaft on the loading plate is located on the side close to the counterweight block.

[0010] The separation tank is used to collect the liquid mixed in the main body of the cold heading machine and store it separately. The separation tank is equipped with a partition plate 1 and a partition plate 2 to divide it into multiple storage chambers. An L-shaped movable plate for guiding the flow of liquid is movably installed on the separation tank.

[0011] A separation assembly is used to separate lubricating oil and coolant in a separation tank by the power generated by the unloading of the discharge assembly. The separation assembly includes a deflector for separating liquids and an arc-shaped bar movably mounted on the main body of the cold heading machine and powered by the deflector. The separation assembly also includes a rack disposed on an L-shaped movable plate and powered by the arc-shaped bar.

[0012] Furthermore, the carrier plate is provided with a fishbone-shaped liquid guiding groove and multiple sets of drainage grooves connected to the fishbone-shaped liquid guiding groove for draining liquid from the carrier plate; the side of the carrier plate away from the counterweight is provided with an interconnected liquid collecting groove and a liquid draining hole for collecting liquid that is not drained from the carrier plate in time and draining it when the carrier plate is unloaded; the discharge assembly is movably mounted with an arc-shaped movable plate covering the liquid draining hole and a filter screen covering the liquid collecting groove. The arc-shaped movable plate is used to open the liquid draining hole to discharge liquid when the carrier plate is tilted, and the filter screen is used to prevent the workpiece from entering the liquid collecting groove when the carrier plate is tilted.

[0013] Furthermore, the main body of the cold heading machine is provided with a protective component to prevent the workpiece from falling when the discharge assembly is not rotating. The discharge assembly is initially tilted, and the end of the discharge assembly near the protective component is lower than the end with the counterweight. A telescopic plate is slidably installed inside the protective component, and the size of the telescopic plate is smaller than the gap between the arc-shaped movable plates after they are fully tilted. This is to prevent the workpiece from sliding out during the tilting process of the arc-shaped movable plate and to ensure that the workpiece is smoothly unloaded after the arc-shaped movable plate reaches its limit position.

[0014] Furthermore, the partition plate and the L-shaped movable plate divide the separation tank into a collection chamber, a coolant chamber, a separation chamber, and a lubricating oil chamber, which are used to store the mixed liquid, coolant, liquid being separated, and lubricating oil respectively, and the coolant chamber and the separation chamber are respectively connected to the collection chamber.

[0015] Furthermore, the second partition plate is lower than the first partition plate. The L-shaped movable plate is initially flush with the first L-shaped movable plate, with its bottom end located above the through hole between the collection chamber and the separation chamber. When the L-shaped movable plate descends to be flush with the second partition plate, the bottom of the L-shaped movable plate covers the through hole between the collection chamber and the separation chamber.

[0016] Furthermore, the dial plate is rotatably mounted on the cold heading machine body, and a gear is provided on one side of the dial plate. The arc-shaped strip is provided with teeth that mesh with the gear, and an elastic element for resetting is provided on the arc-shaped strip. The separation assembly also includes a rack that is movably mounted on the cold heading machine body and meshes with the gear, and the rack is connected to an L-shaped movable plate.

[0017] Furthermore, the dial plate and gear are unidirectionally rotatably connected, so that when the arc-shaped bar is squeezed by the carrying plate, the dial plate and gear slide relative to each other, and when the arc-shaped bar is reset under the action of the elastic element, it drives the dial plate to rotate counterclockwise.

[0018] Furthermore, the circulating spraying assembly is provided with two sets and is respectively connected to the coolant chamber and the lubricating oil chamber, and the liquid outlet is located near the stamping punch and the cutting assembly, which is used to add lubricating oil during extrusion molding and to spray coolant to cool down the workpiece during cutting. The circulating spraying assembly is provided with an elastic filling bladder for buffering liquid and increasing the discharge pressure when the discharge end is opened. Beneficial effects

[0019] The technical solution provided by this invention has the following advantages compared with known public technologies:

[0020] 1. The timing discharge of the discharge assembly drives the rotating plate to separate the lubricating oil and coolant in the mixed liquid. At the same time, the rack and pinion and the moving L-shaped movable plate cause the lubricating oil in the separation chamber to be introduced into the lubricating oil chamber when the L-shaped movable plate descends, and when it rises, it squeezes the coolant in the separation chamber into the liquid collection chamber. Then, the lubricating oil on the upper surface of the separation chamber is introduced into the lubricating oil chamber, which achieves precise separation of lubricating oil. At the same time, no additional energy-consuming equipment is required, reducing energy consumption and making it energy-saving and environmentally friendly.

[0021] Second, by using the combination of the carrying plate and the counterweight, the material is fed into the gap between the batches. When the liquid generated during processing is introduced into the separation tank, the impact force of the liquid entering the separation tank is reduced, preventing the liquid from mixing together and making it difficult to separate. This reduces the difficulty of liquid separation and also prevents the processed workpiece from being damaged due to falling from too high, thus protecting the workpiece. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] The present invention will be further described below with reference to embodiments. Example

[0035] Environmentally friendly intelligent cold heading machine, see attached document. Figure 1-9 It includes the main body 1 of the cold heading machine and the circulating liquid spraying assembly 11 disposed above it.

[0036] Specifically, the circulating spray assembly 11 has two sets, which are respectively connected to the coolant chamber 302 and the lubricating oil chamber 304. The liquid outlet is located near the stamping punch and the cutting assembly. The two sets of circulating spray assemblies 11 circulate and extract the filtered coolant and lubricating oil and spray them onto the equipment. This is used to add lubricating oil during the extrusion molding process and to spray coolant to cool down the workpiece during cutting. The circulating spray assembly 11 is equipped with an elastic filling bladder 111 for buffering the liquid and increasing the discharge pressure when the discharge end is opened. After the liquid is sucked in by the circulating pump, the circulating spray assembly 11 sprays the liquid only when the equipment is extruding or the workpiece is being cut. This saves energy and improves the utilization efficiency of the liquid. It does not need to spray the liquid continuously. On the other hand, when the spray end is closed, the elastic filling bladder 111 expands due to the continuous input of the circulating pump. When the spray end is opened, it can quickly discharge the liquid and make contact with the equipment. At the same time, it will guide the airflow to accelerate the dissipation of heat.

[0037] Also includes:

[0038] The discharge assembly 2 is used to collect workpieces and rotate to unload them when the workpieces reach a certain weight. The discharge assembly 2 includes a carrying plate 21 rotatably connected to the main body 1 of the cold heading machine and a counterweight 24 set on the carrying plate 21. The rotating shaft on the carrying plate 21 is located on the side close to the counterweight 24. Through the setting of the counterweight 24 and the eccentric rotating shaft on the carrying plate 21, the carrying plate 21 automatically flips to unload and collect the workpiece when collecting a certain weight of material, and automatically resets after the workpiece is unloaded. When not unloading, it helps to remove liquid from the workpiece.

[0039] Specifically, the main body 1 of the cold heading machine is provided with a protective component 12 to prevent the workpiece from falling when the discharge assembly 2 is not rotating. The discharge assembly 2 is initially tilted, and the end of the discharge assembly 2 near the protective component 12 is lower than the end with the counterweight 24. In the initial state, the discharge assembly 2 is pressed against the protective component 12 by the counterweight 24. A telescopic plate is slidably installed inside the protective component 12, and the size of the telescopic plate is smaller than the gap size between the arc-shaped movable plates 22 after they are fully tilted. This is to prevent the workpiece from sliding out during the tilting process of the arc-shaped movable plates 22, so that the telescopic plate can remain in contact with the carrying plate 21 during the initial time of the discharge assembly 2's rotation, and ensure that the workpiece is smoothly unloaded after the arc-shaped movable plates 22 are in the extreme position.

[0040] Furthermore, the carrier plate 21 is provided with a fishbone-shaped liquid guiding groove 211 and multiple sets of drainage grooves 212 connected to the fishbone-shaped liquid guiding groove 211 for draining the liquid on the carrier plate 21. The fishbone-shaped liquid guiding groove 211 and drainage groove 212 guide the liquid generated during equipment processing to the side wall of the cold heading machine body 1 and flow into the separation tank 3, reducing the impact force when the liquid enters the separation tank 3, thereby effectively preventing the coolant and lubricating oil from mixing, facilitating stratification and separation. At the same time, the workpiece is tilted out by the carrier plate 21, reducing the probability of workpiece impact damage. The side of the carrier plate 21 away from the counterweight 24 is provided with an interconnected liquid collection groove 2. 13 and drain hole 214 are used to collect liquid that is not discharged in time on the carrier plate 21 and discharge it when the carrier plate 21 is unloaded. Since the carrier plate 21 is tilted in the initial state, when the liquid on the carrier plate 21 cannot be discharged in time, the liquid will be discharged into the liquid collection tank 213. The discharge assembly 2 is movably installed with an arc-shaped movable plate 22 covering the drain hole 214 and a filter screen 23 covering the liquid collection tank 213. The arc-shaped movable plate 22 is used to open the drain hole 214 to discharge the liquid when the carrier plate 21 is tilted, and then the liquid is introduced into the separation tank 3. The filter screen 23 is used to prevent the workpiece from entering the liquid collection tank 213 when the carrier plate 21 is tilted.

[0041] In the above technical solution, the material group is fed through the cooperation of the carrier plate 21 and the counterweight block 24. When the liquid generated during processing is introduced into the separation tank 3, the impact force when the liquid enters the separation tank 3 is reduced, the liquid is prevented from mixing together and making it difficult to separate, the difficulty of liquid separation is reduced, and the processed workpiece is protected from damage caused by falling too high.

[0042] Separation tank 3 is used to collect the liquid mixed in the main body 1 of the cold heading machine and store it separately. Separation tank 3 is provided with a first partition plate 31 and a second partition plate 311 to divide it into multiple storage chambers. An L-shaped movable plate 32 for guiding the flow of liquid is movably installed on separation tank 3.

[0043] The separator 31 and the L-shaped movable plate 32 divide the separation tank 3 into a collection chamber 301, a coolant chamber 302, a separation chamber 303, and a lubricating oil chamber 304, which are used to store the mixed liquid, coolant, liquid being separated, and lubricating oil respectively. The coolant chamber 302 and the separation chamber 303 are respectively connected to the collection chamber 301. The collection chamber 301 is located directly below the discharge assembly 2. The coolant chamber 302 and the lubricating oil chamber 304 are respectively located inside the cold heading machine body 1 to prevent liquid from entering the coolant chamber 302 and the lubricating oil chamber 304 during collection.

[0044] Additionally, the second partition plate 311 is lower than the first partition plate 31. The L-shaped movable plate 32 is initially flush with the first partition plate 31, with its bottom end positioned above the through-hole between the collecting chamber 301 and the separating chamber 303. When the L-shaped movable plate 32 descends to be flush with the second partition plate 311, the lubricating oil floating above the liquid surface in the separating chamber 303 is guided into the lubricating oil chamber 304 for circulation. At this time, the bottom of the L-shaped movable plate 32 covers the through-hole between the collecting chamber 301 and the separating chamber 303, preventing coolant in the collecting chamber 301 from entering the separating chamber 303. After the movable plate 32 rises and becomes flush with the partition plate 31, it separates the separation chamber 303 from the lubricating oil chamber 304. At this time, the lever plate 45 rotates to push the lubricating oil on the upper surface of the liquid collection chamber 301 into the separation chamber 303, so that the liquid level in the separation chamber 303 is higher than that in the liquid collection chamber 301. As the L-shaped movable plate 32 rises, the bottom of the L-shaped movable plate 32 is misaligned with the through hole between the liquid collection chamber 301 and the separation chamber 303. The liquid in the separation chamber 303 will squeeze the coolant at the bottom into the liquid collection chamber 301, thereby preventing coolant from entering the lubricating oil chamber 304 during the process of liquid being introduced from the separation chamber 303.

[0045] In the above technical solution, through the cooperation of the liquid collection chamber 301, coolant chamber 302, separation chamber 303 and lubricating oil chamber 304 inside the separation tank 3, as well as the L-shaped movable plate 32, the lubricating oil floating on the upper surface of the mixed liquid is separated from the coolant in a cyclic manner, and the coolant and lubricating oil are separated into different storage chambers for processing cycle use, with good separation effect.

[0046] The separation component 4 is used to separate the lubricating oil and coolant in the separation tank 3 by the power generated by the unloading of the discharge component 2. The separation component 4 includes a deflector 45 for separating liquids and an arc-shaped bar 41 that is movably mounted on the cold heading machine body 1 and poweredly connected to the deflector 45. The separation component 4 also includes a rack 44 that is mounted on an L-shaped movable plate 32 and poweredly connected to the arc-shaped bar 41.

[0047] Specifically, the lever 45 is rotatably mounted on the cold heading machine body 1. The lever 45 consists of a rotating column and fixed bars arranged in a ring array on the rotating column. The rotating column is rotatably mounted on the cold heading machine body 1, and a gear 43 is provided on one side of the lever 45. The arc-shaped bar 41 is provided with teeth that mesh with the gear 43. The arc-shaped bar 41 moves under the pressure of the carrying plate 21, and at the same time drives the gear 43 to rotate. The arc-shaped bar 41 is provided with an elastic element 42 for resetting. After the workpiece is unloaded from the carrying plate 21, it is used to reset the arc-shaped bar 41 and drive the gear 43 to rotate in the opposite direction again. The separation component 4 also includes a rack 44 movably mounted on the cold heading machine body 1 and meshing with the gear 43. The rack 44 is connected to the L-shaped movable plate 32. Under the rotation of the gear 43, the rack 44 moves vertically upward and downward, thereby driving the L-shaped movable plate 32 to move, so as to realize the connection and separation of the separation chamber 303 with the liquid collection chamber 301 and the lubricating oil chamber 304 respectively.

[0048] It is worth noting that the lever 45 and the gear 43 are unidirectionally rotatably connected. When the arc-shaped bar 41 is squeezed by the carrier plate 21, the lever 45 and the gear 43 slide relative to each other, so that the lubricating oil floating on the upper surface of the liquid collection chamber 301 will not be scraped to the side away from the separation chamber 303. This makes it easier for the lever 45 to scrape the lubricating oil into the separation chamber 303. When the arc-shaped bar 41 is reset under the action of the elastic element 42, it drives the lever 45 to rotate counterclockwise.

[0049] In the above technical solution, the motion of the rotating unloading plate 21 is converted into a driving force for the push plate 45 by the arc-shaped bar 41. The rotation of the push plate 45 scrapes the lubricating oil in the mixed liquid into the separation chamber 303. At the same time, the rack 44 moves the L-shaped movable plate 32. When the L-shaped movable plate 32 descends, it guides the lubricating oil on the upper surface of the separation chamber 303 into the lubricating oil chamber 304. When the L-shaped movable plate 32 rises, it squeezes the coolant at the bottom of the separation chamber 303 into the collection chamber 301. After the lubricating oil is pushed into the separation chamber 303 through the collection chamber 301, the lubricating oil on the upper surface of the separation chamber 303 is then guided into the lubricating oil chamber 304. This achieves precise separation of the lubricating oil without the need for additional energy-consuming equipment, reducing energy consumption and making it energy-saving and environmentally friendly.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
