Description

Technical Field

[0001] The utility model belongs to the technical field of casting equipment, and in particular relates to a fully automatic quantitative feeding equipment for casting. Background Art

[0002] The feeding process is an important link in the casting process, especially in the casting process of precision structural parts. The requirements for the feeding process are particularly strict, and the deviation of the feeding weight is often controlled below 0.5% of the feeding amount.

[0003] The traditional feeding method is to use manual labor to complete the four feeding steps of material distribution, weighing, transportation, and feeding. Under the premise that the main casting process is getting shorter and shorter, manual feeding obviously cannot meet the requirements of the casting process for the efficiency of the feeding process. Taking the die-casting of small precision structural parts as an example, the die-casting machine only takes 90 to 120 seconds to normally inject one mold, while a single person needs at least 3 to 5 minutes to complete the material distribution, weighing, transportation, and feeding. Therefore, when using traditional manual feeding, 3 to 5 people are often required at the feeding station. Excessive use of manual feeding not only leads to a sharp increase in costs, but also the weight of the feed varies from person to person (the deviation of each person's weighing is different), and the weight of the feed of the same batch will have a large deviation, which is difficult to meet the requirements for feeding consistency. With the improvement of the existing technology, the work of material distribution and weighing in the feeding process can be completed by quantitative combination weighers, which can greatly improve the consistency and efficiency of material distribution-weighing. However, there are still many problems that cannot be automated in terms of transportation and feeding, resulting in the current feeding equipment in the casting field mostly using quantitative combination weighers + manual methods, and the feeding process has not been fully automated. There is no research on full automation of the above-mentioned processes in the prior art, and there is almost no improvement in the efficiency of material sorting, weighing, transportation and feeding in the casting field. Summary of the invention

[0004] The utility model aims to provide a fully automatic quantitative feeding device for casting, aiming to solve the technical problem that the feeding process in the casting process in the prior art cannot be fully automated.

[0005] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is as follows:

[0006] The utility model provides a fully automatic quantitative feeding equipment for casting, including a frame as a fixed installation frame of the equipment and a control system for controlling the feeding process, including a cup feeding mechanism, a quantitative combination scale, a translation mechanism, a clamping mechanism and a turnover assembly; an empty material cup enters through the cup feeding mechanism and moves to the drop port of the quantitative combination scale, the quantitative combination scale weighs the raw material of a set weight and puts it into the empty material cup, the translation mechanism moves the material cup filled with the raw material to the clamping station, and the clamping mechanism transfers the material cup filled with the raw material to the turnover assembly;

[0007] It also includes a clamping slide rail group arranged on the frame and on both sides of the clamping mechanism. The clamping mechanism is provided with a clamping slider group and a power mechanism adapted thereto. The clamping mechanism performs reciprocating motion along the clamping slide rail group to transfer the material cup.

[0008] The utility model divides the quantitative feeding process into four sub-sections: cup feeding, weighing, cup transfer, and turnover. The feeding equipment and feeding method in the utility model are compatible with the precision casting process. The casting of each mold has precise requirements on the quality of raw material feeding, so a single cup feeding method is adopted, and the equipment and method in the utility model are used in conjunction with the single cup feeding method.

[0009] Preferably, the cup feeding mechanism includes a cup feeding channel, a cup feeding belt, a limit block group arranged on both sides of the cup feeding belt, and an empty cup clamping mechanism; the feeding end of the cup feeding belt receives the empty cup, and the discharging end is the feeding end of the cup feeding channel, and the empty cup falls into the empty cup clamping mechanism from the cup feeding channel and is clamped to the dropping port of the quantitative combination weigher; the empty cup clamping mechanism is a mechanical clamp.

[0010] The cup feeding mechanism in the utility model adopts a single cup feeding method to transport empty cups, and the cup feeding belt cooperates with the empty cup clamping mechanism to complete the automatic cup feeding. The cups adapted to the device and method in the utility model preferably adopt plastic cups with a thickness greater than 1mm and good strength and toughness. Such cups are not only low in cost, light, and easy to stack during transportation, but also will not cause damage to the equipment if they collide with the equipment.

[0011] Preferably, the translation mechanism includes a fixed plate arranged at the bottom and a cup-dropping fixing platform fixedly connected thereto; elastic clamping components are arranged on both sides of the cup-dropping fixing platform, and an elastic cup clamping station is arranged on the elastic clamping component for clamping the material cup dropped on the cup-dropping fixing platform; one end of the cup-dropping fixing platform is set as the first elastic cup clamping station below the dropping port of the quantitative combination weigher, and the other end is set as a clamping station, and a sensor is arranged at the clamping station; the bottom of the elastic clamping component is fixedly connected to the cup feeding slider group, and the fixed plate is provided with a cup feeding slide rail group matched therewith, and the elastic clamping mechanism is driven by the power mechanism of the cup feeding slider group to reciprocate from the first elastic cup clamping station to the clamping station.

[0012] The fixed plate in the translation mechanism and the cup-dropping fixing platform are connected fixed structures, which are fixed in position and are used to carry and guide the movement of the material cup. The elastic clamping assembly is used to push the material cup to move on the cup-dropping fixing platform, so that the loaded material cup moves step by step to the clamping station according to the settings.

[0013] Preferably, the table top of the cup dropping fixing table and the fixing plate are inclined at an angle of 2-5°, which is more conducive to the material cup having an inclination in the movement direction and more conducive to the material cup moving from the elastic cup clamping station to the clamping station.

[0014] Preferably, the elastic clamping assembly in the utility model constitutes a total of 3 elastic cup clamping stations, and the elastic clamping assembly is composed of a first elastic clamping part and a second elastic clamping part of a symmetrical structure. The elastic clamping assembly includes a first elastic clamping part and a second elastic clamping part, and the first elastic clamping part and the second elastic clamping part form an elastic cup clamping station after closing; there are 3 elastic cup clamping stations, namely the first elastic cup clamping station, the second elastic cup clamping station and the third elastic cup clamping station; the opening and closing directions of the first elastic clamping part and the second elastic clamping part are perpendicular to the movement direction of the material cup. Theoretically, setting up one elastic cup clamping station or two elastic cup clamping stations can complete the action of cup transfer, but in actual operation, setting up one elastic cup clamping station will greatly reduce the efficiency of cup transfer, losing the original intention of developing automatic feeding equipment. Setting two elastic cup clamping stations seems to be able to solve the above problems, but in actual use, it is found that only setting two elastic cup clamping stations will cause interference between the elastic clamping assembly and the clamping mechanism, thereby causing instability and vibration during the cup transfer process. Increasing the number of elastic cup clamping stations to three will solve all the problems. Setting more elastic cup clamping stations will only increase the moving distance and will not bring obvious advantages. Therefore, the present invention chooses to set three elastic cup clamping stations.

[0015] Preferably, the bottom of the elastic clamping assembly is a bottom plate, and the two ends of the elastic clamping assembly are also provided with an elastic slider group and an elastic slide rail group for controlling the opening and closing of the first elastic clamping part and the second elastic clamping part, and the elastic slide rail group is fixedly mounted on the bottom plate; the middle part of the elastic clamping assembly is also provided with an elastic cylinder for providing power for opening and closing the first elastic clamping part and the second elastic clamping part. The elastic slider-slide rail group independently controls the opening and closing of the elastic clamping assembly, and the elastic cylinder provides power for it.

[0016] Preferably, in order to increase the stability of the elastic clamping assembly, the first elastic clamping part is fixedly mounted on the first elastic clamping part mounting block, and the second elastic clamping part is fixedly mounted on the second elastic clamping part mounting block; an elastic slider is fixedly mounted at both ends of the bottom of the first elastic clamping part mounting block and the second elastic clamping part mounting block, and the above-mentioned elastic sliders together constitute the elastic slider group; the lower end of the elastic slider group is provided with an elastic slide rail group with a length matching it.

[0018] Preferably, the clamping mechanism comprises a clamping beam, a clamping assembly and a motion control device of the clamping assembly, and the motion control device comprises a horizontal slider-horizontal slide rail assembly and a vertical slider-vertical slide rail assembly;

[0019] The two ends of the clamping beam are provided with clamping slider groups, which are compatible with the clamping slide rail group on the frame; the front side of the clamping beam is provided with a horizontal slider-horizontal slide rail assembly to control the movement of the clamping assembly along the clamping beam in the horizontal direction, the horizontal slide rail is fixedly installed on the front side of the clamping beam, and the horizontal slide rail is provided with a horizontal slider compatible with it; the non-slip surface side of the horizontal slider is fixedly connected to the vertical slide rail, and the vertical slide rail is provided with a vertical slider compatible with it, the movement direction of the vertical slider is perpendicular to the clamping beam, and the vertical slide rail and the vertical slider constitute a vertical slider-vertical slide rail assembly to control the movement of the clamping assembly in the vertical direction;

[0020] The clamping assembly comprises a clamping jaw and a clamping jaw mounting block fixedly connected thereto, and the clamping jaw mounting block is fixedly mounted on the vertical sliding block.

[0021] The above structure enables the clamping mechanism to move not only horizontally along the clamping beam, but also vertically to place and stack the material cups.

[0022] Preferably, the turnover assembly includes a movable orifice plate and a fixed orifice plate separately stacked on the bottom of the movable orifice plate, the movable orifice plate and the fixed orifice plate have the same shape, and are provided with array-type cup-dropping holes on the plate bodies, the inner diameter of the cup-dropping holes is larger than the outer diameter of the material cup; the fixed orifice plate is fixedly installed on the frame, and inclined top cylinders are provided on both sides of the movable orifice plate.

[0023] The fully automatic quantitative feeding method using the above-mentioned feeding equipment comprises the following steps:

[0024] S1, the first material cup enters through the cup inlet channel, and then is moved to the material outlet of the quantitative combination weigher by the empty cup clamping mechanism;

[0025] S2, the quantitative combination weigher weighs the alloy raw material according to the set weight, and then drops the raw material into the first material cup;

[0051] In order to make the purpose, technical scheme and technical effect of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model is clearly and completely described. The embodiments described below are part of the embodiments of the utility model, not all of the embodiments. In combination with the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. If the specific conditions are not specified in the embodiments, they are carried out according to the conventional conditions or the conditions recommended by the manufacturer; the reagents or instruments used without indicating the manufacturer are all conventional products that can be purchased commercially.

[0052] Unless the context clearly states otherwise, expressions in the singular form of a word should be understood to include the plural form of the word. The terms "include" or "have" are intended to specify the presence of a feature, quantity, step, operation, element, part, or combination thereof, but are not used to exclude the presence or possible addition of one or more other features, quantities, steps, operations, elements, parts, or combinations thereof.

[0053] The embodiment of the utility model provides a fully automatic quantitative feeding device for casting, and its overall structure diagram is shown in the accompanying drawings.

[0054] The feeding device provided in the embodiment includes a frame 110 as a fixed installation frame of the device and a control system (not shown in the figure) for controlling the feeding process. Figure 1What can be seen in the figure is the control system display screen 106, and the operation of the feeding process can be performed by touching the display screen 106. The control system in this embodiment can use a computer software control system, a PLC or other common control device, which will not be described in detail here.

[0055] Specifically, the feeding equipment includes a cup feeding mechanism, a quantitative combination weigher, a translation mechanism, a clamping mechanism, and a turnover assembly. The cup feeding mechanism is used to sequentially introduce empty material cups, the quantitative combination weigher is used to quantitatively weigh the raw materials and pour them into the material cups, the translation mechanism is used to transfer the material cups to the turnover assembly, and the turnover assembly is used to batch turnover of the material cups. Furthermore, the empty material cups enter through the cup feeding mechanism and move to the drop port 104 of the quantitative combination weigher, the quantitative combination weigher weighs the set weight of raw materials and puts them into the empty material cups, the translation mechanism moves the material cups filled with raw materials to the clamping station, and the clamping mechanism transfers the material cups filled with raw materials to the turnover assembly.

[0056] The quantitative combination weigher in this embodiment adopts a commercially available product, as long as it is a combination weighing product that meets the quantitative weighing requirements of the utility model. Therefore, in the drawings of the utility model, the quantitative combination weigher is not drawn, and only the drop port 104 is used to indicate its relative position.

[0057] Furthermore, it also includes a clamping slide rail group 105 arranged on the frame 110 and on both sides of the clamping mechanism. The clamping mechanism is provided with a clamping slider group 202 and its power mechanism adapted thereto. The clamping mechanism reciprocates along the clamping slide rail group 105 to transfer the material cup.

[0058] It should be noted that, since there are many loading equipment components in this embodiment, and the slide rails and sliders are mostly used in pairs or groups, in order to make the drawings clear, only one of the slide rails or slider groups is marked in the drawings of this embodiment. Those skilled in the art should be able to see without a doubt that another one or more will be provided on the opposite side or in a relative position. Moreover, in the process of explaining the structure of this embodiment, one marked slide rail or slider is used to represent the group of slide rails or sliders. The above description method should also be clear to those skilled in the art. Figure 1 Taking the clamping rail assembly 105 and the clamping slider assembly 202 in the figure as an example, it can be known without a doubt that on the other side of the clamping mechanism (within the dotted circle) there are rails and sliders set up opposite to 105 and 202 marked in the figure.

[0059] Another thing that needs to be explained is that the "horizontal direction" and "vertical direction" described in the present invention are more used to explain the relative positions between components, rather than the absolute positions of components. Therefore, the position of the components in the present invention should not be limited to the absolute "horizontal" or "vertical", but should be limited in combination with the relative positions of the components constituting the components and the functions to be achieved.

[0060] Furthermore, the cup feeding mechanism includes a cup feeding channel 101, a cup feeding belt 103, a limit block group 102 arranged on both sides of the cup feeding belt 103, and an empty cup clamping mechanism ( Figure 1 Not shown in the figure). The feeding end of the cup feeding belt 103 receives the empty cup, and the discharging end is the feeding end of the cup feeding channel 101. The empty cup falls directly into the empty cup clamping mechanism from the cup feeding channel 101 under the action of gravity, and is clamped to the drop port 104 of the quantitative combination weigher. The empty cup clamping mechanism is a mechanical clamp, or other manipulator devices with clamping function can also be used. In the cup feeding mechanism, a single cup enters the device from the cup feeding belt 103, and the limit block groups 102 on both sides make the cup only move along the belt until it falls into the cup feeding channel 101. The cup feeding channel 101 can adopt an open upright trough structure, such as the attached Figure 1 The U-shaped open trough structure.

[0061] The empty material cup enters the cup feeding mechanism and moves to the material drop port 104 of the quantitative combination weigher. The quantitative combination weigher takes the set weight of raw materials and puts them into the empty material cup. The translation mechanism moves the material cup filled with raw materials to the clamping station. Figure 2 To Attachment Figure 6 shown.

[0062] From the attached Figure 2 As can be seen in the figure, the translation mechanism includes a fixed plate 309 arranged at the bottom and a cup-dropping fixed platform 307 fixedly connected thereto. Elastic clamping components are arranged on both sides of the cup-dropping fixed platform 307, and an elastic cup clamping station is arranged on the elastic clamping component to clamp the material cup dropped on the cup-dropping fixed platform 307. One end of the cup-dropping fixed platform 307 is set as the first elastic cup clamping station (the position of the first material cup 301 in the figure) below the drop port of the quantitative combination weigher, and the other end is set as a clamping station 305, and a sensor 304 is arranged at the clamping station, which is a position sensor. When the sensor 304 senses that there is an object here, the clamping mechanism is started. The bottom of the elastic clamping component is fixedly connected to the cup-delivering slider group 306, and a cup-delivering slide rail group 308 adapted thereto is arranged on the fixed plate 309. The elastic clamping mechanism reciprocates from the first elastic cup clamping station 301 to the clamping station 305 under the drive of the cup-delivering slider group power mechanism 310 (translation power cylinder).

[0063] By the attached Figure 2 To Attachment Figure 6 It can be seen that the cup-feeding slider group 306 not only includes the Figure 3 The pair of sliders appearing in the translation mechanism also includes a pair of sliders set opposite to each other on the other side of the translation mechanism. Figure 3 The slide rail that can be seen in the figure also includes a slide rail set up on the other side of the translation mechanism, and the slide rail is provided with a pair of sliders set up on the other side that are not seen, and the structure is similar to the attached Figure 3306 and 308 shown in the middle have the same position and structure.

[0064] It is further preferred that the table top of the cup-dropping fixing table 307 and the fixing plate 309 have an inclination angle of 2 to 5 degrees, that is, the first elastic cup clamping station 301 is located a little higher, which is more conducive to the material cup having a tendency in the movement direction and more conducive to the material cup moving from the elastic cup clamping station to the clamping station.

[0065] As attached Figure 4 To Attachment Figure 6 The elastic clamping assembly includes a first elastic clamping part 312 and a second elastic clamping part 313. The first elastic clamping part 312 and the second elastic clamping part 313 are closed to form an elastic cup clamping station. There are three elastic cup clamping stations, namely the first elastic cup clamping station 301, the second elastic cup clamping station 302 and the third elastic cup clamping station 303. The opening and closing directions of the first elastic clamping part 312 and the second elastic clamping part 313 are perpendicular to the movement direction of the material cup.

[0066] The bottom of the elastic clamping assembly is a bottom plate 311. The two ends of the elastic clamping assembly are also provided with an elastic slider group and an elastic slide rail group for controlling the opening and closing of the first elastic clamping part 312 and the second elastic clamping part 313. The elastic slide rail group is fixedly mounted on the bottom plate 311. The middle part of the elastic clamping assembly is also provided with an elastic cylinder 320 for providing power for opening and closing the first elastic clamping part 312 and the second elastic clamping part 313. The elastic cylinder 320 in this embodiment is a telescopic cylinder.

[0067] The first elastic clamping part 312 is fixedly mounted on the first elastic clamping part mounting block 314, and the second elastic clamping part 313 is fixedly mounted on the second elastic clamping part mounting block 315. An elastic slider is fixedly mounted at each of the bottom ends of the first elastic clamping part mounting block 314 and the second elastic clamping part mounting block 315, which are respectively the first elastic slider 316 (including the elastic slider in the figure and the elastic slider at the opposite side of the lower end of the first elastic clamping part) and the second elastic slider 317 (including the elastic slider in the figure and the elastic slider at the opposite side of the lower end of the first elastic clamping part). The above four elastic sliders together constitute an elastic slider group. The lower end of the elastic slider group is provided with an elastic slide rail group of a length matching the elastic slider group, including the first elastic slide rail 318 and the second elastic slide rail 319. The middle parts of the first elastic clamping part mounting block 314 and the second elastic clamping part mounting block 315 are fixedly connected to the cylinder connecting block 321 , and the elastic cylinder 320 is fixedly connected to the cylinder connecting block 321 .

[0068] Attached Figure 6The structure of a single elastic clamping part is shown in the figure: the elastic clamping part includes three clamping blocks fixedly installed on the elastic clamping part mounting block 314 at equal distances, namely the first clamping block 3134, the second clamping block 3135, and the third clamping block 3136. Each clamping block is installed with a clamping head with a semicircular arc inside, namely the first clamping head 3131, the second clamping head 3132, and the third clamping head 3133. Each clamping block is connected to the corresponding clamping head through a spring device, such as the first clamping head 3131 and the first clamping block are connected through a spring 3137. Such a structure enables the elastic clamping part to maintain elastic clamping when clamping the material cup, making the material cup more stable during movement, and also enables the clamping mechanism to adapt to a variety of material cups with different outer diameters.

[0069] As attached Figure 7 To Attachment Fig. 9 The clamping mechanism includes a clamping beam 201, a clamping assembly, and a motion control device for the clamping assembly, and the motion control device includes a horizontal slider-horizontal slide rail assembly and a vertical slider-vertical slide rail assembly. In this embodiment, 203 is a wire trough, and the power line of the equipment can be installed in the wire trough.

[0070] The clamping beam is provided with a clamping slider group 202 at both ends, which is compatible with the clamping slide rail group 105 on the frame. A horizontal slider-horizontal slide rail assembly is provided on the front side of the clamping beam to control the movement of the clamping assembly along the clamping beam in the horizontal direction. The horizontal slide rail 204 is fixedly installed on the front side of the clamping beam, and a horizontal slider 210 adapted thereto is provided on the horizontal slide rail. The non-slip surface side of the horizontal slider 210 is fixedly connected to the vertical slide rail 205, and the vertical slide rail 205 is provided with a vertical slider 206 adapted thereto. The movement direction of the vertical slider 206 is perpendicular to the clamping beam 201. The vertical slide rail 205 and the vertical slider 206 constitute a vertical slider-vertical slide rail assembly to control the movement of the clamping assembly in the vertical direction. The clamping assembly also includes a clamping jaw 208 and a clamping jaw mounting block 207 fixedly connected thereto, and the clamping jaw mounting block 207 is fixedly installed on the vertical slider 206. The clamping jaw 208 is used to clamp the cup body 209.

[0071] As attached Figure 1 The turnover assembly includes a movable orifice plate 107 and a fixed orifice plate 108 which is separately stacked on the bottom of the movable orifice plate 107, that is, the fixed orifice plate 108 is fixed on the frame 110, and the movable orifice plate 107 can be provided with movable mechanisms on both sides to drive the movable orifice plate 107 to move up and down, so as to change the height of the movable orifice plate according to needs. The movable orifice plate 107 and the fixed orifice plate 108 have the same shape, and are provided with array-type cup-dropping holes on the plate body. The inner diameter of the cup-dropping holes is larger than the outer diameter of the material cup, and the cup-dropping holes play the role of limiting the material cup. There are also inclined top cylinders 109 on both sides of the movable orifice plate 107, and the inclined top cylinders can be as shown in the attached Figure 1 As shown, the movable orifice plate 107 is lifted up to facilitate taking out the material cups that have been divided and stacked on the fixed orifice plate.
