Description

Technical Field

[0001] The present invention relates to the technical field of mold steel cleaning, and specifically provides a pre-cleaning device for the processing of mold steel billets. Background Art

[0002] Mold steel billets are the basic materials for precision mold manufacturing. Before processing, they usually exist in the form of rolled steel plates and are widely used in high-precision industries such as automobiles, aerospace, and electronics. Their surface quality directly affects the life and performance of the molds. Before processing, the billets need to go through multiple processes such as forging, cutting, and heat treatment. During rolling, storage, and transportation, oxide scales will form on the surface, and contaminants such as cutting fluid, rust preventive oil, and dust will adhere to it. If not thoroughly removed, impurities will accelerate tool wear, cause micro-cracks on the processing surface, and even lead to defects such as pores or stress concentration in the finished mold. Therefore, pre-cleaning is the core link connecting billet preparation and finishing. Traditional cleaning mostly relies on manual spraying for cleaning.

[0003] However, in current technologies, it is difficult for manual spraying to accurately cover the cleaning surface of mold steel billets, which easily causes surface residues or local over-flushing damage, resulting in problems of reduced cleaning uniformity and cleaning efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a pre-cleaning device for the processing of mold steel billets, which solves the problems of easy surface residues or local over-flushing damage, resulting in reduced cleaning uniformity and cleaning efficiency.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A pre-cleaning device for the processing of mold steel billets includes a housing.

The outer wall of the transmission column is fixedly connected with a first moving gear. The outer wall of the first moving gear is meshed with a first rack. The inner wall of the moving frame is fixedly connected with a guide rail. The outer wall of the guide rail is slidably connected with a positioning block.

The outer wall of the second moving gear is meshed with a second rack. A cleaning component is arranged on the upper surface of the housing.

[0006] By adopting the above technical solution: the support frame is fixedly supported by the outer shell, the support frame provides a sliding guide for the moving frame, the moving frame fixes the first motor, the first motor drives the rotating column to rotate, and drives the transmission shaft to be linked by the first bevel gear engaging the second bevel gear, so that the first moving gear and the first rack are engaged and transmitted. Based on the reverse force, the moving frame slides laterally along the support frame, and synchronously pulls the scraper assembly to move. The guide rail fixed on the moving frame supports the sliding of the positioning block, and the second motor drives the longitudinal movement of the positioning block by engaging the second moving gear with the second rack. Through the dual-axis coordination of the first motor and the second motor, the cleaning assembly is driven to achieve lateral and longitudinal multi-degree-of-freedom movement, accurately control the spraying or brushing trajectory, solve the problem of blind spots in fixed path cleaning, and improve the flexibility and uniformity of pollution residue removal. At the same time, it reduces manual intervention and adapts to the continuous operation requirements of automated production lines.

[0007] Preferably, the scraper assembly includes a side frame, the outer wall of the side frame is fixedly connected to the outer wall of the movable frame, the inner wall of the side frame is slidably connected to two movable plates, and the two movable plates on the inner wall of the side frame are both provided with brushes, and the brushes are used to clean the waste on the surface of the mold steel blank.

[0008] Preferably, a positioning column is fixedly connected to the lower surface of the movable plate on the lower side of the inner wall of the side frame, a sleeve is slidably connected to the outer wall of the positioning column, a diamond plate is fixedly connected to the bottom end of the sleeve, the lower surface of the diamond plate is slidably connected to the inner wall of the outer shell, inclined grooves are provided on both sides of the inner wall of the outer shell, and a material receiving trough is fixedly connected to the lower surface of the outer shell.

[0009] Preferably, the outer wall of the shell is fixedly connected to a hydraulic cylinder, the output end of the hydraulic cylinder is fixedly provided with a guide frame, the inner wall of the guide frame is rotatably connected to a connecting plate, and the interior of the connecting plate is rotatably connected to a support column.

[0010] Preferably, the outer wall of the support column is fixedly connected with a first clamping plate, and the outer wall of the first clamping plate is slidably connected to the inner wall of the support frame.

[0011] Preferably, the outer wall of the first clamping plate is fixedly connected to a linkage plate, the outer wall of the linkage plate is slidably connected to the inside of the movable plate, the outer wall of the linkage plate is fixedly connected to a second clamping plate, and the outer wall of the second clamping plate is slidably connected to the inner wall of the shell.

[0012] Preferably, both side outer walls of the shell are fixedly connected with ventilation racks, the inner wall of the ventilation rack is provided with a fan, the inner wall of the ventilation rack is provided with a filter plate, and two slots are opened inside the filter plate.

[0013] Preferably, two fixed boxes are fixedly connected to the upper surface of the ventilation rack. A pressure plate is slidably connected to the inner wall of the fixed box. A limiting inclined block is fixedly connected to the lower surface of the pressure plate, and the outer wall of the limiting inclined block is arranged on the inner wall of the clamping groove.

[0014] Preferably, a pull plate is fixedly connected to the outer wall of the pressure plate, a spring is fixedly connected to the upper surface of the pressure plate, and the top end of the spring is fixedly connected to the inner wall of the fixed box.

[0015] Working principle: When the equipment is needed, first send the mold steel blank to be cleaned from the front end of the opening of the outer shell to the upper surface of the second clamping plate until the other end of the mold steel blank is located on the upper surface of the first clamping plate. At this time, start the hydraulic cylinder, and the output end of the hydraulic cylinder can drive the guide frame to move backward. Thus, the connecting plate pulls the first clamping plates at the upper and lower ends through the support columns to slide centeringly on the inner wall of the support frame until the first clamping plates at the upper and lower ends are in close contact with the upper and lower surfaces of the mold steel blank. The second clamping plate at the opening of the outer shell can be driven by the first clamping plate through the linkage plate to be in close contact with the upper and lower surfaces of the mold steel blank synchronously, realizing the fixation of the mold steel blank, thereby ensuring the stability of the mold steel blank during cleaning. And the linkage plate can drive the moving plate to slide on the inner wall of the side frame, driving the brush on the moving plate to be in positioning contact with the surface of the mold steel blank, thereby eliminating the crosstalk during the processing of the blank and ensuring the uniform cleaning of the surface oxide layer or residues by the brush; After the mold steel blank is fixed, the high-pressure pump in the liquid storage tank transmits the stored cleaning liquid to the nozzle through the high-pressure pipe to spray the surface of the mold steel blank. During the spraying process, start the first motor, and the output end of the first motor drives the rotating column to rotate. Then, the rotating column drives the second bevel gears at both ends to rotate synchronously through the first bevel gear. The rotation of the second bevel gear can drive the transmission column to rotate. After that, the transmission column drives the first moving gear to rotate. And the first moving gear drives the moving frame to move on the upper surface of the support frame through the reverse force with the first rack, driving the nozzle to position the cleaning position of the mold steel blank. At the same time, start the second motor, and the output end of the second motor drives the second moving gear to rotate. The second moving gear drives the fixing plate to move through the positioning block through the reverse force with the second rack, thereby further increasing the spraying range of the nozzle. By the technical personnel controlling the start of the first motor and the second motor, multi-axis positioning cleaning of the nozzle is realized, improving the cleaning effect; While the moving frame slides on the upper surface of the support frame, the side frames on both sides can be driven to slide synchronously, so that the side frames drive the moving plate to move, so as to drive the brush to clean the waste and waste liquid on the surface of the mold steel blank. Then, the moving plate drives the diamond plate to slide on the inner wall of the shell through the positioning column and the sleeve, and pushes the waste liquid on the lower inner wall of the shell into the chute on both sides. The waste is transported to the receiving trough through the guidance of the chute, so as to achieve the effect of synchronous cleaning and waste recovery. After cleaning one side of the mold steel blank, the mold steel blank is taken out and turned over for secondary cleaning. After cleaning, turn on the fans on both sides. The fans quickly pass the external air into the interior of the shell through the filter plate to form convection, and quickly dry the surface of the mold steel blank. When the filter plate needs to be cleaned later, pull the pull plate to drive the limiting bevel block to separate from the inner wall of the slot through the pressure plate, and pull the handle outside the filter plate to remove the filter plate from the inner wall of the ventilation frame. At the same time, when installing the filter plate, push the filter plate into the inner wall of the ventilation frame. At this time, release the pull plate, and the spring rebounds to push the limiting bevel block to contact the inner wall of the slot through the pressure plate, thereby realizing the fixed installation of the filter plate, ensuring the air quality during air drying, and preventing external air impurities from interfering with the air drying effect.

[0016] The present invention provides a pre-cleaning device for processing mold steel blanks. It has the following beneficial effects: 1. The present invention starts the first motor to drive the rotating column to rotate, and links the transmission columns on both sides through the bevel gear set to drive the driving gear to engage with the rack, so that the movable frame moves laterally, and at the same time starts the second motor to drive and push the fixed plate to move longitudinally, expand the coverage range of the nozzle, realize the multi-axis coordinated movement of the nozzle, complete the dynamic and precise cleaning of the surface of the blank, and effectively improve the cleaning uniformity and efficiency.

[0017] 2. The present invention starts the hydraulic cylinder to drive the guide frame to move backward, and the upper and lower first clamps are linked by the connecting plate and the support column to slide in the center, clamping the upper and lower surfaces of the blank, and the linkage plate synchronously drives the second clamp to clamp, so as to fix the blank. At the same time, the linkage plate drives the moving plate in the side frame to slide, so that the brush can accurately contact the surface of the blank, inhibit processing movement, ensure that the oxide layer and residue are evenly cleaned, and improve the cleaning stability and cleaning effect.

[0018] 3. The present invention drives the side frames on both sides to move synchronously when the moving frame slides. The side frames are linked to the moving plate and the brush to clean the waste material and waste liquid on the surface of the blank. The moving plate drives the diamond plate to slide along the inner wall of the shell through the positioning column and the sleeve, and pushes the bottom waste liquid into the inclined grooves on both sides. The inclined groove guides the waste material into the receiving groove through the inclination angle, thereby realizing the synchronous operation of cleaning and waste material recovery, avoiding secondary pollution and improving the cleaning efficiency.

[0019] 4. In the present invention, by starting the two-side fans, the external air enters the housing through the filter plate to form convection, quickly air-drying the surface of the blank. After that, the pull plate is pulled to disengage the limiting inclined block from the card slot, and the filter plate is taken out. During installation, the filter plate is pushed in, and after releasing the pull plate, the spring rebounds, and the inclined block is snapped into the card slot for fixation, ensuring clean air and avoiding interference of impurities with the air-drying effect.
