Description

Technical Field

[0001] The present invention relates to the field of belt buckles, and particularly to a production device and a slag removal and separation method for zinc alloy belt buckles. Background Art

[0002] With the increasing improvement of living standards, zinc alloy belt buckle castings have the following special structures in production: 1. There are small slag discharges at the bottom of the product part of the casting; 2. The large slag discharge of the casting has an upper and lower two-layer structure and the product part is a hollow structure; 3. The product part of the casting has raised feet; 4. The product parts are distributed on the left and right sides of the pouring gate and are close to the pouring gate. Therefore, for a long time, only manual production can be relied on to separate the slag on the belt buckle casting. However, the connection strengths between the small slag discharge and the large slag discharge and the casting are different. When separating the casting, the labor intensity of manual operation is very high, wasting manpower and material resources, and it is easy to pollute the environment and the production efficiency is low.

[0003] Reference Figure 9 And Figure 10 are the schematic structural diagrams of casting 6. After the casting 6 is formed in the mold, it includes a shunt nozzle 61 protruding upward in the middle, runners 62 arranged on both sides of the shunt nozzle 61, a pouring gate 63 connected to the runners 62, a belt buckle product part 64 connected to the pouring gate 63, a large slag discharge 65 connected to the side edge of the belt buckle product part 64, and a small slag discharge 66 connected to the bottom of the product part. Summary of the Invention

[0004] Therefore, in view of the above problems, the present invention proposes a production device for zinc alloy belt buckles. It solves the technical problem of low production efficiency of belt buckles.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A production device for zinc alloy belt buckles includes a frame. A separation mechanism is provided on the frame. The separation mechanism includes an ultrasonic transducer and a vibration head that can be lifted and lowered on the frame, an ultrasonic generator connected to the ultrasonic transducer, a first lifting mechanism for driving the ultrasonic transducer and the vibration head to lift and lower, and a mounting seat provided on the frame. The ultrasonic transducer is connected to the vibration head. The ultrasonic transducer is of an inverted horn type. The vibration head is arranged above the mounting seat. A profiling die is provided on the mounting seat. At least one first vibration plate and at least one second vibration plate are provided on the profiling die. Elastic materials are respectively installed below the first vibration plate and the second vibration plate. The elastic modulus of the elastic material below the first vibration plate is greater than that of the elastic material below the second vibration plate.

[0007] Furthermore:

[0008] The frame is provided with a clamping mechanism, which includes a slide rail horizontally arranged on the frame, at least one slider slidably arranged on the slide rail, a driving mechanism for driving the transmission slider to slide, a second lifting mechanism arranged on the slider, a lifting seat liftably arranged on the second lifting mechanism, and a clamping device arranged on the lifting seat, and the clamping device can be moved above the mounting seat.

[0009] The slide rail is located on one side of the separation mechanism, and the lifting seat is an L-shaped structure.

[0010] The frame is provided with a conveying mechanism, and the conveying mechanism is provided with a casting positioning mechanism, the positioning mechanism includes two first telescopic cylinders symmetrically arranged on the frame, and squaring plates arranged on the two first telescopic cylinders, and a squaring area is formed between the two squaring plates, the positioning mechanism includes a casting in-place sensor arranged on the frame, the positioning mechanism includes a second telescopic cylinder arranged on the frame, and a baffle connected to the second telescopic cylinder, the baffle can be abutted against the end of the conveying mechanism, and the baffle can move along the conveying direction.

[0011] The elastic material under the first vibration plate is a hard spring, there is one first vibration plate, and the first vibration plate is arranged in the middle of the mold; the elastic material of the second vibration plate is a soft spring, there are two second vibration plates, and the second vibration plates are arranged on both sides of the mold.

[0012] The mounting seat is provided with at least one product drop port, and a slag discharge mechanism is provided below the mounting seat, and the slag discharge mechanism includes a guide plate obliquely arranged on the frame, the top end of the guide plate is the feed end, and the bottom end of the guide plate is the discharge end, and at least one vibration device is provided on the guide plate, and at least one leakage trough is provided on the guide plate, and a reverse slope is connected to the edge of the leakage trough close to the discharge end, and the reverse slope is inclined downward toward the feed end, and at least one slag discharge frame is provided on the frame below the leakage trough; and a collecting frame is provided on the frame at the lower end of the discharge end.

[0013] The ultrasonic generator is a high-power automatic frequency tracking phase-locked generator.

[0014] The working center frequency of the ultrasonic generator is 15kHz.

[0015] The elastic modulus of the elastic material under the first vibration plate is relatively large, so that the vibration head can press the flow channel of the casting, and the ultrasonic energy is well coupled to the flow channel of the casting and transmitted as a transverse wave. The elastic modulus of the elastic material under the second vibration plate is relatively small, so that the vibration head only contacts the large slag of the casting but does not press it, and the ultrasonic energy is not coupled to the large slag of the casting, and continuously hits the large slag of the casting at high speed to perform longitudinal wave vibration.

[0016] A concave hole is provided at the bottom of the vibration head to avoid the runner of the casting. On both sides of the concave hole at the bottom of the vibration head, there are protrusions for pressing the runner of the casting and protrusions for impacting the large slag discharge of the casting.

[0017] The present invention also provides a slag discharge separation method based on the above-mentioned zinc alloy belt buckle production device, including the following steps:

[0018] (1) The casting is placed in the mold on the mounting seat. The first lifting mechanism drives the vibration head to press down. There are protrusions at the bottom of the vibration head. The protrusions of the vibration head for pressing the runner of the casting press the runner of the casting. The protrusions of the vibration head for impacting the large slag discharge of the casting contact the large slag discharge. The elastic modulus of the elastic material below the first vibration plate must be relatively large so that the vibration head can press the runner of the casting, and the ultrasonic energy can be well coupled into the runner of the casting and conduct as transverse waves. The elastic modulus of the elastic material below the second vibration plate must be relatively small so that the vibration head only contacts the large slag discharge of the casting without pressing it, and the ultrasonic energy is not coupled into the large slag discharge of the casting, and continuously impacts the large slag discharge of the casting at high speed to perform longitudinal wave vibration;

[0019] (2) The ultrasonic generator outputs an ultrasonic signal to the ultrasonic transducer. The ultrasonic transducer conducts the ultrasonic wave to the vibration head. The vibration head conducts the ultrasonic wave onto the casting. The protrusion of the vibration head at the second vibration plate contacts the large slag discharge of the casting but does not press it. The large slag discharge of the casting is continuously impacted by the longitudinal wave vibration of the ultrasonic wave, causing it to break due to metal fatigue, separating the large slag discharge from the product part; avoiding the deformation of the product part of the casting with a double-layer hollow structure due to being squeezed up and down by the large slag discharge;

[0020] (3) The protrusion of the ultrasonic vibration head at the first vibration plate presses the runner of the casting, couples the ultrasonic energy into the runner of the casting and conducts as transverse waves. Utilizing the stress concentration effect of the shear stress generated by the transverse wave conduction of the ultrasonic wave, the ultrasonic transverse wave first melts the weakest connection part on the casting, and then melts from the weakest part to the stronger part on the casting in sequence. Since the small slag discharge at the bottom of the product part of the casting has the weakest connection, the ultrasonic transverse wave will first melt the small slag discharge at the bottom of the product part, and then melt the belt buckle product part; the ultrasonic transverse wave and the ultrasonic longitudinal wave act on the large slag discharge of the casting at the same time, causing it to separate from the product part of the casting first, realizing the sequential separation of the small slag discharge, large slag discharge and belt buckle product part of the casting.

[0021] Furthermore:

[0022] The time for ultrasonic separation of large slag discharge is 1 second to 2 seconds, the time for ultrasonic fusing of small slag discharge is 0.3 second to 1 second, the small slag discharge is fused prior to the large slag discharge, and finally the product part of the casting is fused. Therefore, the area where the vibrating head presses against the casting runner must be controlled below 0.2 square centimeters to control the ultrasonic energy coupled to the casting runner and prevent the product part of the casting from being fused prior to the large slag discharge.

[0023] When the vibrating head presses down, the elastic material below the first vibrating plate is compressed by 50%, and the elastic material below the second vibrating plate is compressed by 25%.

[0024] By adopting the foregoing technical solutions, the beneficial effects of the present invention are as follows:

[0025] The separation mechanism of the present invention can separate large slag discharge, small slag discharge, waste materials, and belt buckle products on the casting, realizing automatic separation of the equipment, improving production efficiency, and saving a large amount of labor costs; the setting of the first vibrating plate, due to the relatively large elastic modulus of the elastic material below the first vibrating plate, can ensure that the protrusion of the vibrating head presses tightly against the runner of the casting, and ultrasonic energy can be well coupled into the runner of the casting. Ultrasonic transverse wave conduction occurs in the casting, and the stress concentration effect generated by the shear stress of the transverse wave conduction sequentially fuses the small slag discharge and the product part in the casting, and has a certain shock absorption effect to prevent the equipment from being damaged by hard impacts; due to the relatively small elastic modulus of the elastic material below the second vibrating plate, this structure allows the protrusion of the vibrating head to not only contact the large slag discharge of the casting and separate the large slag discharge of the casting by using ultrasonic longitudinal waves, but also not squeeze the large slag discharge of the double-layer structure to prevent the large slag discharge from driving the product part of the hollow structure to deform. The separation of large slag discharge, small slag discharge, waste materials, and belt buckle product parts on the casting is realized; further, the clamping mechanism can clamp and place the casting in the mold on the mounting seat and clamp the separated waste materials away from the mold on the mounting seat, realizing automated production; further, the conveying mechanism conveys the casting, and the positioning mechanism can align the casting conveyed on the conveying mechanism so that the clamping device can accurately clamp the casting. At the same time, when the clamping device fails to pick up the casting, the positioning mechanism can move the in-place baffle away to prevent the unclamped casting from colliding with subsequent castings and piling up at the in-place baffle; further, the belt buckle products on the slag discharge mechanism can fall into the collection box, and the large slag discharge and small slag discharge fall from the leakage trough into the slag discharge box, realizing the separation of belt buckle product parts, large slag discharge, and small slag discharge.

[0038] The clamping mechanism 3 includes a slide rail 31 horizontally arranged on the frame 1, two sliders 32 slidably arranged on the slide rail 31, a driving mechanism 33 driving the transmission slider 32 to slide, a second lifting mechanism 34 arranged on the slider 32, a lifting seat 35 slidably arranged on the second lifting mechanism 34, and a clamping device 36 arranged on the lifting seat 35, and the clamping device 36 can be moved to the top of the mounting seat 25. The slide rail 31 is located on one side of the separation mechanism, and the lifting seat 35 is an L-shaped structure.

[0039] A positioning mechanism is provided on the conveying mechanism 4, and the positioning mechanism includes a straightening cylinder 41 and a blocking cylinder 42. The straightening cylinder 41 includes two first telescopic cylinders 411 symmetrically arranged on the frame 1, and a straightening plate 412 arranged on the two first telescopic cylinders 411, and a straightening area is formed between the two straightening plates 412. The blocking cylinder 42 includes a second telescopic cylinder 421 arranged on the frame 1, and a baffle 422 connected to the second telescopic cylinder 421. The baffle 422 can be abutted against the end of the conveying mechanism 4, and the baffle 422 can move along the conveying direction.

[0040] The above-mentioned positioning mechanism may be provided with a casting in-place sensor 43 for sensing the position of the casting, which is a well-known device and will not be described in detail here.

[0041] The slag discharge mechanism is arranged below the mounting base 25, and the slag discharge mechanism includes a guide plate 51 obliquely arranged on the frame 1, the top end of the guide plate 51 is the feed end, the bottom end of the guide plate 51 is the discharge end, a vibration device 52 is provided on the guide plate 51, a plurality of leakage grooves 53 are provided on the guide plate 51, and a reverse slope 54 is connected to the edge of the leakage groove 53 close to the discharge end, and the reverse slope 54 is inclined downward toward the feed end. A slag discharge frame 55 is provided on the frame 1 below the leakage groove 53; a collection frame 56 is provided on the frame 1 at the lower end of the discharge end.

[0042] The clamping device 36 is a well-known device and will not be described in detail here.

[0043] The above-mentioned backing mold is located on the mounting base 25. The backing mold is a template that can be used to install the first vibration plate and the second vibration plate. The backing mold is provided with a hole slightly smaller than the product drop opening 250. The backing mold can also have other structures. The backing mold can also be integrally formed with the mounting base 25 and be a part of the mounting base 25. It is a well-known structure and will not be repeated here.

[0044] The casting may also be other structures. The number of the first vibration plates 26 may be one, two, three or even more, and the number of the second vibration plates 27 may be one, two, three or even more, depending on the structure of the casting 6 .

[0045] The above ultrasonic generator usually adopts an externally excited high-power automatic frequency tracking and phase-locked generator, or can also adopt a self-excited ultrasonic generator or other ultrasonic generators, which are well-known devices. Since the large slag discharge of the casting only contacts the vibration head and is not pressed tightly, the large slag discharge of the casting must be separated prior to the product part of the casting to prevent the unseparated large slag discharge from falling together with the product part of the casting. However, because the large slag discharge of the casting has a double-layer hollow structure, there must be a certain time delay in separating the upper layer of slag discharge first and then the lower layer of slag discharge. The higher the working center frequency of the ultrasonic wave, the greater the energy carried by the ultrasonic wave, and the greater the energy coupled into the casting through the flow channel of the casting. The shorter the time for the shear stress concentration effect generated by the ultrasonic wave transmitted by the transverse wave to fuse the joints of the casting in sequence. It is difficult to ensure that the large slag discharge of the casting is separated prior to the product part of the casting at a higher working frequency. Therefore, the working center frequency usually adopts 15 kHz, or can also be other frequencies, which are specifically set according to the situation.

[0046] The above elastic material can be a hard spring, a soft spring or other elastic components. The hard spring and soft spring can be made of steel springs, which are well-known components and will not be elaborated here. When the vibration head presses down, the elastic material under the first vibration plate is usually compressed by 50%, and the elastic material under the second vibration plate is usually compressed by 25%, or can also be other compression percentage values, which are specifically set according to the situation.

[0047] The above first lifting mechanism 24, second lifting mechanism 34, and driving mechanism 33 can adopt cylinders, oil cylinders, linear motors or other linear motion mechanisms, which are well-known devices and will not be elaborated here.

[0048] The above conveying mechanism 4 can be a conveyor belt or other conveying mechanisms 4, which are well-known devices and will not be elaborated here.

[0049] The present invention also provides a slag discharge separation method based on the above-mentioned zinc alloy belt buckle production device, including the following methods:

[0050] (1) After the casting 6 is formed in the mold and is conveyed by the conveying mechanism 4, when the casting 6 is located in the positioning area, the casting in-place sensor 43 acts, and then triggers the two first telescopic cylinders 411 to drive the alignment plate 412 to move, clamp the casting 6 correctly, so that the shunt nozzle of the casting 6 is located at a suitable position on the conveyor belt. The conveyor belt transports the casting 6 to the baffle 422. One of the clamping devices 36 of the clamping mechanism clamps the casting 6 on the conveying mechanism 4 and moves it into the profile in the mounting seat 25. At the same time, the other clamping device 36 of the clamping mechanism clamps the waste in the profile in the mounting seat 25 and moves it into the waste collection box 56.

[0051] (2) The casting 6 is located in the master mold on the mounting seat 25, the first lifting mechanism 24 drives the vibration head 22 to press down, the diverter nozzle 61 is inserted into the concave hole 222, and the vibration head 22 is pressed down to press against the flow channel 62 of the casting 6. The flow channel 62 of the casting 6 located at the first vibration plate 261 is pressed between the vibration head 22 and the first vibration plate 261;

[0052] (3) The ultrasonic generator 23 outputs an ultrasonic signal to the ultrasonic transducer 21, and the ultrasonic transducer transmits the ultrasonic wave to the vibration head 22. The vibration head 22 transmits the ultrasonic wave to the flow channel 62 of the casting 6. The vibration head 22 located at the second vibration plate 271 contacts the large slag 65 of the casting 6 but does not press the large slag 65 of the casting 6. The large slag 65 of the casting 6 at this position has longitudinal vibration. The large slag 65 of the casting 6 is continuously impacted by the ultrasonic longitudinal wave vibration, so that it breaks due to metal fatigue, and the large slag 65 is separated from the product part. The time for the ultrasonic longitudinal wave to separate the large slag 65 is 1 second to 2 seconds; Figure 10 The large slag discharge 65 includes an upper slag discharge 651 and a lower slag discharge 652 arranged up and down. When the large slag discharge is separated, the vibration head 22 first separates the upper slag discharge 651 by longitudinal waves, and then the vibration head 22 contacts the lower slag discharge 652 to separate the lower slag discharge 652.

[0053] (4) The ultrasonic wave is transmitted laterally on the casting 6, and the stress concentration effect of the shear stress generated by the transverse wave transmission of the ultrasonic wave is utilized. The ultrasonic transverse wave first melts the weakest part of the casting connection, and then melts from the weak part to the strong part on the casting 6. The ultrasonic transverse wave melts the small slag 66 at the bottom of the casting 6, and then melts the belt buckle product part 64; the ultrasonic transverse wave and the ultrasonic longitudinal wave act on the large slag 65 on the casting 6 at the same time, and separate the large slag 65 on the casting 6 from the belt buckle product part 64 of the casting. The time for the ultrasonic transverse wave to melt the small slag 66 is 0.3 seconds to 1 second, and the small slag 65 melts before the large slag 66; finally, the product part 64 melts.

[0054] (5) The large slag 65, the small slag 66, and the belt buckle product 64 fall onto the guide plate 51 through the product drop opening 250 on the mounting plate. The vibrating device 52 on the guide plate 51 vibrates, and the large slag 65, the small slag 66, and the belt buckle product 64 slide downward. The large slag 65 and the small slag 66 pass through the material leakage trough 53 and fall onto the slag discharge frame 55. The belt buckle product 64 can pass over the material leakage trough 53 and fall onto the collection frame 56.

[0055] (6) At this time, the waste is placed in the mold on the mounting seat 25, and one of the clamping devices 36 of the clamping mechanism clamps the casting 6 on the conveyor belt and moves it to the mold on the mounting seat 25. At the same time, another clamping device 36 of the clamping mechanism clamps the waste of the casting 6 in the mold on the mounting seat 25 and moves it to the waste collection frame 56 for the next round of process.

[0056] Although the present invention has been specifically shown and described in connection with preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in form and detail without departing from the spirit and scope of the present invention defined by the appended claims, and all such changes are within the scope of protection of the present invention.
