Description

Technical Field

[0001] This utility model belongs to the technical field of top hammer processing equipment, and particularly relates to a processing equipment for the small inclined surface of a cemented carbide top hammer. Background Technology

[0002] The carbide top hammer is a critical and vulnerable component in a six-sided top press. Under high temperature and pressure, its four small beveled surfaces are highly susceptible to the adhesion of impurities such as sintered pyrophyllite. These deposits can damage the seal between the top hammer and the hinge beam, leading to oil leaks, unstable pressure, and even serious safety accidents such as explosions. Therefore, it is crucial to clean the small beveled surfaces of the top hammer promptly before and after use.

[0003] Currently, manual scraping and wire brush polishing are commonly used. These methods rely heavily on the experience and physical strength of the operators, resulting in high labor intensity, slow cleaning speed, and difficulty in meeting the rapid maintenance needs of large-scale production lines. Furthermore, the cleaning effect is poor and damage is easily caused. In addition, the pyrophyllite dust generated during the cleaning process permeates the air, posing a certain degree of harm to the respiratory system of the operators.

[0004] To address the shortcomings of existing technologies, this utility model discloses a processing device for the small inclined surface of a cemented carbide top hammer. By setting a sleeve that fits into the main body of the top hammer, and setting a cleaning and processing mechanism for cleaning the small inclined surface of the top hammer and a dust collection mechanism for dust recovery inside the sleeve, a high degree of automation, good cleaning effect, minimal damage to the top hammer body, and dust collection are achieved.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention provides a treatment device for the small inclined surface of a cemented carbide top hammer. By setting a sleeve that is sleeved with the main body of the top hammer, and setting a cleaning treatment mechanism for cleaning the small inclined surface of the top hammer and a dust collection mechanism for dust collection inside the sleeve, the device achieves a high degree of automation, good cleaning effect, minimal damage to the top hammer body, and dust collection.

[0017] (2) The present invention provides a treatment device for the small inclined surface of a cemented carbide top hammer. By setting up a cleaning and treatment mechanism, the four cleaning brushes rotate synchronously, in the same direction and at the same speed, ensuring that the force applied to the four small inclined surfaces of the top hammer and the cleaning stroke are consistent, avoiding the problem of uneven sealing surface caused by uneven cleaning, and the cleaning effect is uniform. Moreover, the brush bristles are all made of flexible abrasive filaments, which contact the small inclined surface of the top hammer under the preset mechanical structure, and can reduce the wear caused to the cemented carbide body when removing the attached pyrophyllite.

[0018] (3) The present invention provides a treatment device for the small inclined surface of a hard alloy top hammer. By setting up a dust suction mechanism and an abutting air guide, when the dust suction mechanism is working, the external airflow can flow into the large inclined surface of the top hammer through the air guide channel on the abutting air guide. When passing through the small inclined surface of the top hammer, it can bring the dust in this area into the collection chamber. The cleaning and dust suction process is completed in a relatively closed system, which avoids the escape of dust, improves the working environment, and prevents operators from inhaling harmful dust.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] This utility model provides a device for processing the small inclined surface of a cemented carbide top hammer, for reference. Figure 1-3 As shown, the device includes a sleeve 1. The front end of the sleeve 1 has a first chamber 3 for engaging with the top hammer body 2. A circular seat 4 is coaxially arranged inside the first chamber 3. A frustum-shaped opening 5 extends through the circular seat 4 from front to back. The larger diameter end of the frustum-shaped opening 5 is positioned close to the top hammer body 2. Four abutment air guides 7 are respectively provided on the four inner walls of the frustum-shaped opening 4 for abutting against the four large inclined surfaces 6 of the top hammer. A rectangular groove 8 is provided on the rear end face of the circular seat 4 along the edge of the smaller diameter end of the frustum-shaped opening 5. The rectangular groove 8 is equipped with a cleaning mechanism 10 for treating the deposits on the small inclined surface 9 of the top hammer. The rear end of the sleeve 1 has a collection chamber 11, inside which a dust collection mechanism 12 is installed. A handle 13 is also provided on the outer side of the rear end of the sleeve 1. The handle 13 has a collection chamber inside, which communicates with the collection chamber 11 and contains a dust collection box 14. The handle 13 also has a switch 15 for controlling the operation of the cleaning mechanism 10 and the dust collection mechanism 12. The frustum-shaped opening 5 and the abutment strip 71 are designed to create a funnel effect. The operator only needs to roughly fit the device onto the top hammer body 2, and the structure will guide the frustum-shaped opening 5 to align with the large inclined surface 6 of the top hammer, positioning the cleaning mechanism 10 at the small inclined surface 9 of the top hammer, reducing operational difficulty and fatigue. The cleaning, dust collection, and vacuuming functions are highly integrated into a single handheld device, avoiding the hassle of dragging an external vacuum hose, making it very convenient to move and use.

[0027] The abutment air guide 7 includes several abutment strips 71 arranged along the slope direction of the frustum-shaped opening 5. The end face of each abutment strip 71 away from the frustum-shaped opening 5 abuts against the large inclined surface 6 of the top hammer. A guide channel 72 for allowing air to enter the collection chamber 11 is formed between pairs of adjacent abutment strips 71. (Reference) Figure 3 The air guide component 7 consists of several abutment strips 71 arranged along the slope direction of the frustum-shaped opening 5. The abutment strips 71 abut against the large inclined surface 6 of the top hammer, serving both a centering and positioning function and forming pre-set air guide channels 72 between each pair of abutment strips 71. This arrangement facilitates the entry of outside air; outside air can only enter through these specific air guide channels, far from the cleaning area, and after flowing through the large inclined surface 6 of the top hammer, it finally flows into the collection chamber 11. This airflow effectively prevents dust from diffusing outside the equipment and directs it entirely into the collection chamber 11.

[0028] The cleaning mechanism 10 includes a first cleaning brush 101, a second cleaning brush 102, a third cleaning brush 103, and a fourth cleaning brush 104 arranged sequentially along the circumference of the rectangular groove 8. These four brushes form a square shape, simultaneously cleaning the four small inclined surfaces of the top hammer's small inclined surface 9. One end of the first cleaning brush 101 rotates around an axis via a motor 105, and this end is connected to the fourth cleaning brush 104 via a first bevel gear pair. The other end of the first cleaning brush 101 is connected to the second cleaning brush 102 via a second bevel gear pair, and the other end of the fourth cleaning brush 104 is connected to the third cleaning brush 103 via a third bevel gear pair. The cleaning mechanism 10 consists of four cleaning brushes arranged in a square, linked together by a set of bevel gear pairs. Only one motor 105 drives the first cleaning brush, and the power is then transmitted sequentially to the fourth cleaning brush 104, the second cleaning brush 102, and the third cleaning brush 103 via the first, second, and third bevel gear pairs. This ensures that the four brushes rotate synchronously, in the same direction, and at the same speed. This results in consistent cleaning force on the four small bevels, leading to uniform and efficient cleaning, and avoids additional stress caused by asynchrony, thus protecting the top hammer. The rotational motion of the brush bristles effectively cleans the complex contours and tiny pits on the surface of the top hammer's small bevel 9, superior to the linear motion of manual scraping. The four cleaning brushes are linked by precise gear pairs, simultaneously processing all four top hammer small bevels 9, which is at least four times more efficient than cleaning each surface manually. From fitting the top hammer body 2 to turning on the switch, the entire process requires no heavy physical labor or complex skills, making it easy for ordinary workers to operate.

[0029] The first cleaning brush 101 includes a first transmission rod, on which a first brush cylinder is coaxially mounted, and the first brush cylinder is provided with first bristles. The upper and lower ends of the first transmission rod are respectively connected to the bottom of the rectangular groove 8 through a first bearing, and the lower end of the first transmission rod is coaxially connected to the rotating shaft of the motor 105.

[0030] The second sweeping brush 102 includes a second transmission rod, on which a second brush cylinder is coaxially mounted, and the second brush cylinder is provided with second bristles. The left and right ends of the second transmission rod are respectively connected to the bottom of the rectangular groove 8 through second bearings. The third sweeping brush 103 includes a third transmission rod, on which a third brush cylinder is coaxially mounted, and the third brush cylinder is provided with third bristles. The upper and lower ends of the third transmission rod are respectively connected to the bottom of the rectangular groove 8 through third bearings. The fourth sweeping brush 104 includes a fourth transmission rod, on which a fourth brush cylinder is coaxially mounted, and the fourth brush cylinder is provided with fourth bristles. The left and right ends of the fourth transmission rod are respectively connected to the bottom of the rectangular groove 8 through fourth bearings.

[0031] The first, second, third, and fourth bristles are flexible abrasive filaments, made of nylon or polyester fiber, with embedded abrasive particles most commonly silicon carbide or alumina. The flexible filaments bend upon contact with the hard surface of the top hammer. This bending results in very low actual contact pressure between the abrasive grains and the workpiece surface. Brush cleaning relies primarily on the numerous micro-scratching actions of the abrasive grains. Its material removal rate is extremely low; it is not designed for dimensional cutting but rather for removing surface deposits. Pyrophyllite has a low hardness, far lower than cemented carbide and abrasive. Therefore, during cleaning, the abrasive particles preferentially remove the lower-hardness pyrophyllite deposits. Only after the pyrophyllite is removed will the abrasive grains directly contact the cemented carbide body. Due to the low contact pressure, even with direct contact, the removal rate is negligible, producing only a very slight finishing effect, insufficient to change the geometry and precision of the top hammer, let alone cause damage. Employing flexible bristles and operating under constant force, it removes deposits without damaging the cemented carbide substrate, effectively protecting the expensive top hammer.

[0032] The first bevel gear pair includes a first bevel gear and a second bevel gear, with the first bevel gear coaxially mounted on the first transmission rod and the second bevel gear coaxially mounted on the fourth transmission rod; the second bevel gear pair includes a third bevel gear and a fourth bevel gear, with the third bevel gear coaxially mounted on the first transmission rod and the fourth bevel gear coaxially mounted on the second transmission rod; the third bevel gear pair includes a fifth bevel gear and a sixth bevel gear, with the fifth bevel gear coaxially mounted on the fourth transmission rod and the sixth bevel gear coaxially mounted on the third transmission rod.

[0033] The dust collection mechanism 12 includes a fan 121 located at the rear end of the collection chamber 11. A filter screen 122 is coaxially arranged inside the collection chamber 11 at the air inlet end of the fan 121, and the filter screen 122 is located behind the handle part 13. An air outlet is provided at the rear end of the sleeve 1 at the air outlet end of the fan 121, and a protective net 123 is provided inside the air outlet.

[0034] The upper end of the dust collection box 14 is open, and the lower end of the handle 13 is provided with a cover. By using the built-in fan 105 and the dust collection box 14, the cleaning, dust suction and collection are integrated. The dust generated during cleaning is instantly sucked into the collection chamber 11, filtered by the filter screen 122, clean air is discharged, and the dust falls into the dust collection box 14. The whole process is completely closed and no dust escapes.

[0035] The switching component 15 includes a first switch for controlling the operation of the motor 105 and a second switch for controlling the operation of the fan 121.

[0036] Working principle: The operator holds the handle 13 of the device, aligns the opening at the front end of the sleeve 1 with the top hammer to be cleaned, and gently pushes the device forward to fit the top hammer body 2 into the first chamber 3. At this time, the four large inclined surfaces of the top hammer will slide in along the inclined surfaces of the frustum-shaped opening 5 and fit with the internal abutting air guide 7, and the operator will feel a clear sense of positioning. Then, press the switch 15 on the handle 13 (usually designed to start the motor 105 and the fan 121 at the same time), and the device will start working. Keep the device stable on the top hammer, and clean it by relying on the flexibility of the bristles themselves without applying additional pressure. After cleaning is completed, release the switch to stop the motor 105 and fan 121 from working. Pull the device straight back from the top hammer to remove it. After each use, open the cover at the bottom of the handle 13, take out the dust collection box 14, and pour the collected dust into the designated waste recycling container.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
