Description

Technical Field

[0001] The utility model relates to the technical field of die steel processing, in particular to a polishing device for die steel processing. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. In the later stage of mold steel production, due to the presence of many burrs on the surface of the mold steel, a mold steel grinder is required to grind and polish the surface of the mold steel.

[0003] At present, a Chinese patent discloses a mold steel grinder (publication number CN220372858U). By setting a protective collection mechanism, the debris and sparks generated by the mold steel grinder when grinding and polishing the mold steel are first blocked in the processing chamber to ensure the safety of the operator. At the same time, the vacuum fan extracts the air in the placement groove, so that there is a pressure difference between the placement groove and the processing chamber, so that the debris and sparks in the processing chamber are sucked into the debris collection box through the chip discharge groove, which is easy to operate.

[0004] Since the collection box is arranged on the air inlet side of the vacuum pump, if the vacuum pump is to be able to quickly extract the air inside the placement tank, a sufficient gap must be set between the vacuum pump and the collection box. During this process, dust, debris and other impurities will inevitably be sucked into the gap. Although the above-mentioned device has a protective net at the air inlet end of the vacuum pump, impurities will also be retained on the dustproof net, and the staff still needs to clean it, which increases the labor intensity of the staff.

[0005] Therefore, a polishing device for die steel processing is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a polishing device for mold steel processing in order to solve the above-mentioned problem, which improves the problem that the existing mold steel processing polishing device with a debris cleaning function has a poor cleaning effect and still requires staff to take the initiative to clean.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, a polishing device for mold steel processing, comprising: a protective box, a grid plate, an electric rotating clamp and a polishing machine, the grid plate, the electric rotating clamp and the polishing machine are all installed inside the protective box, and one end of the electric rotating clamp passes through the outside of the protective box; a cleaning device, the cleaning device is installed inside the protective box, and one end of the cleaning device passes through the outside of the protective box.

[0008] Preferably, the cleaning device includes a collection box, an air pump and a sealing mechanism, the collection box is inserted between the protection box and the grille plate, one end of the collection box is embedded with a dustproof mesh plate, the air inlet end of the air pump is fixedly connected and connected to a first air duct, one end of the first air duct passes through the interior of the protection box and is in contact with and connected to the dustproof mesh plate, the sealing mechanism is installed on the surface of the grille plate, the air pump can suck impurities inside the protection box into the collection box by tightly attaching to the dustproof mesh plate, and the dustproof mesh plate can filter and intercept impurities in the passing airflow, so that the impurities are always inside the collection box, which effectively reduces the probability of impurities flowing to the outside of the collection box, thereby reducing the intensity of subsequent cleaning and maintenance by the staff.

[0009] Preferably, the surface of the first air duct is fixedly connected and communicated with a uniformly distributed first air scoop, one end of which passes through the interior of the protective box and contacts and communicates with the dustproof mesh plate, which can increase the air suction range of the air pump to improve the attraction rate of impurities.

[0010] Preferably, one end of the first air guide hopper is fixedly connected to a rubber sealing ring, and one end of the rubber sealing ring is in contact with the dustproof mesh plate, which can make the first air guide hopper and the dustproof mesh plate contact more closely to reduce the probability of a gap between the first air guide hopper and the dustproof mesh plate.

[0011] Preferably, the air outlet end of the air pump is fixedly connected and communicated with a second air duct, and one end of the second air duct is fixedly connected and communicated with the inner top wall of the protective box. This can drive the airflow inside the protective box to always flow from top to bottom, effectively reducing the probability of impurities floating and suspended inside the protective box, and can accelerate the flow rate of the airflow inside the protective box, further improving the collection rate of impurities.

[0012] Preferably, the surface of the second air duct is fixedly connected and communicated with evenly distributed second air scoops, and one end of the second air scoop is fixedly connected and communicated with the inner top wall of the protective box, which expands the gas distribution range of the reflux gas and expands the range of restriction and collection.

[0014] Preferably, the inside of the adjusting airbag is fixedly connected with evenly distributed rubber springs, and the rubber springs are perpendicular to the adjusting strip. When the protective box door is separated from the adjusting strip, the rubber springs can quickly reset the adjusting airbag and the adjusting strip. The adjusting airbag then draws back the gas inside the frame-shaped airbag, causing the frame-shaped airbag to quickly deflate and retract into the first installation cavity, so that the staff can normally pull out the collection box.

[0015] Preferably, a rectangular groove connected to the first installation cavity is opened on the top of the collection box, and the vertical cross-section of the rectangular groove is arc-shaped, which can increase the contact strength and contact area between the square-shaped airbag and the collection box when it is inflated, and lock the collection box in the protective box more stably.

[0016] The beneficial effects of the utility model are:

[0017] 1. The air pump can suck the impurities inside the protective box into the collection box by sticking to the dustproof mesh plate, and the dustproof mesh plate filters and intercepts the impurities in the passing airflow, so that the impurities are always inside the collection box, effectively reducing the probability of impurities flowing to the outside of the collection box, thereby reducing the intensity of subsequent cleaning and maintenance by the staff;

[0018] 2. When the worker closes the door of the protection box, the sealing mechanism expands automatically and seals the gap between the protection box and the grille plate, which further reduces the probability of airflow passing through the gap between the protection box and the grille plate, and further reduces the probability of impurities falling outside the collection box.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on 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.

[0026] When implementing: Figure 1-5 As shown, a polishing device for mold steel processing includes: a protection box 1, a grid plate 2, an electric rotating fixture 3 and a polishing machine 4, wherein the grid plate 2, the electric rotating fixture 3 and the polishing machine 4 are all installed inside the protection box 1, and one end of the electric rotating fixture 3 penetrates to the outside of the protection box 1; a cleaning device 5, which is installed inside the protection box 1, and one end of the cleaning device 5 penetrates to the outside of the protection box 1;

[0027] The electric rotating clamp 3 includes two clamping electric push rods which are rotatably connected to two vertical inner walls of the protection box 1. The opposite ends of the two clamping electric push rods are fixedly connected to clamping plates. One end of one of the clamping electric push rods is fixedly connected to a servo motor fixedly connected to the protection box 1. When the staff puts the mold steel between the two clamping plates and then manually controls the two clamping electric push rods to extend, the clamping electric push rods drive the clamping plates to approach the mold steel until the two clamping plates clamp the two ends of the mold steel. When the staff needs to rotate and polish the mold steel, the staff manually controls the servo motor to rotate, and the servo motor The machine drives the clamping electric push rod connected to it to rotate, and the clamping electric push rod drives the mold steel to rotate through the clamping plate connected to it, so that the polishing machine 4 can grind different surfaces of the mold steel; the inner top wall of the protective box 1 is fixedly connected with a horizontal electric push rod, one end of the horizontal electric push rod is fixedly connected with a vertical electric push rod, and the bottom of the vertical electric push rod is fixedly connected to the polishing machine 4. The staff can adjust the horizontal polishing position of the polishing machine 4 by manually controlling the extension and retraction of the horizontal electric push rod, and adjust the vertical polishing position of the polishing machine 4 by manually controlling the extension and retraction of the vertical electric push rod, so that the polishing machine 4 can polish different positions of the mold steel.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cleaning device 5 includes a collection box 51, an air pump 52 and a sealing mechanism 53. The collection box 51 is inserted between the protection box 1 and the grid plate 2. One end of the collection box 51 is embedded with a dustproof mesh plate 54. The air inlet end of the air pump 52 is fixedly connected and connected with a first air guide pipe 55. One end of the first air guide pipe 55 passes through the interior of the protection box 1 and contacts and communicates with the dustproof mesh plate 54. The sealing mechanism 53 is installed on the surface of the grid plate 2; the surface of the first air guide pipe 55 is fixedly connected and connected with uniformly distributed first air guide hoppers 56. The first air guide hoppers 55 are fixedly connected and connected with the first air guide hoppers 56. One end of the first air guide 56 penetrates into the interior of the protective box 1 and contacts and communicates with the dustproof mesh plate 54; one end of the first air guide 56 is fixedly connected to a rubber sealing ring 57, and one end of the rubber sealing ring 57 contacts the dustproof mesh plate 54; the air outlet end of the air pump 52 is fixedly connected to and communicates with a second air guide pipe 58, and one end of the second air guide pipe 58 is fixedly connected to and communicates with the inner top wall of the protective box 1; the surface of the second air guide pipe 58 is fixedly connected and communicated with uniformly distributed second air guide hoppers 59, and one end of the second air guide hopper 59 is fixedly connected to and communicates with the inner top wall of the protective box 1;

[0029] After the air flow passes through the air pump 52, the air flow is introduced into the second air duct 58 by the air pump 52. The second air duct 58 transports the air flow from top to bottom into the protective box 1 through the second air hopper 59. This can drive the air flow inside the protective box 1 to always flow from top to bottom, effectively reducing the probability of impurities floating and suspended inside the protective box 1, and can accelerate the flow rate of the air flow inside the protective box 1, further improving the collection rate of impurities.

[0030] like Figure 4 and Figure 5 As shown, a first mounting cavity 21 is provided at the bottom of the grille plate 2, a second mounting cavity 22 communicating with the first mounting cavity 21 is provided on the surface of the grille plate 2, a sealing mechanism 53 comprises a square frame-shaped airbag 531 fixedly connected to the inner top wall of the first mounting cavity 21, a connecting tube 532 is fixedly connected and communicated with the surface of the square frame-shaped airbag 531, one end of the connecting tube 532 is fixedly connected and communicated with an adjusting airbag 533, one end of the adjusting airbag 533 is fixedly connected to an adjusting strip 534 slidably connected to the second mounting cavity 22, one end of the adjusting strip 534 passes through the outside of the second mounting cavity 22; uniformly distributed rubber springs 535 are fixedly connected to the inside of the adjusting airbag 533, and the rubber springs 535 are perpendicular to the adjusting strip 534; a rectangular groove 511 communicating with the first mounting cavity 21 is provided on the top of the collecting box 51, and the vertical cross-section of the rectangular groove 511 is in the shape of an arc;

[0031] When the staff is closing the door of the protective box 1, the door of the protective box 1 will contact the adjustment strip 534 and squeeze it into the second installation cavity 22. The adjustment strip 534 squeezes the adjustment airbag 533. The adjustment airbag 533 squeezes the gas inside it into the frame-shaped airbag 531 through the connecting tube 532. At this time, the frame-shaped airbag 531 expands downward along the first installation cavity 21 until it contacts the rectangular groove 511. At this time, the gap between the protective box 1 and the grille plate 2 is sealed, which further reduces the probability of airflow passing through the gap between the protective box 1 and the grille plate 2, and further reduces the probability of impurities falling to the outside of the collection box 51.

[0032] When the utility model is in use, during the normal polishing of the mold steel by the polishing machine 4, the air pump 52 directly draws the air inside the collection box 51 through the first air guide pipe 55 and the first air guide hopper 56 through the dustproof mesh plate 54, which effectively reduces the probability of the airflow flowing along the gap between the collection box 51 and the grille plate 2, and reduces the probability of impurities falling to the outside of the collection box 51. At this time, an air pressure difference is generated inside and outside the collection box 51, and the air inside the protective box 1 will be sucked into the collection box 51. During this process, the airflow can carry impurities such as debris and dust polished by the polishing machine 4 into the collection box 51, and the dustproof mesh plate 54 filters and intercepts impurities in the passing airflow, so that the impurities are always inside the collection box 51, further reducing the probability of impurities flowing to the outside of the collection box 51, thereby reducing the intensity of subsequent cleaning and maintenance by the staff.

[0033] It should be noted that the clamping electric push rod, servo motor, horizontal electric push rod, vertical electric push rod, polishing machine 4 and air pump 52 in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the clamping electric push rod, servo motor, horizontal electric push rod, vertical electric push rod, polishing machine 4 and air pump 52 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
