Description

Technical Field

[0001] This invention relates to the field of iron mold sand casting technology, and in particular to an iron mold sand-coated slow cooling line changing device. Background Technology

[0002] With the promotion of iron mold sand-coated casting ball production lines and the continuous improvement of equipment technology, as well as the general increase in the skill level of workers, the production capacity of single lines in the wear-resistant casting industry has been greatly improved. The large number of casting products requires a larger area for storage, which directly increases the workload of workers in collection, hoisting, and cleaning; at the same time, the shortening of the online solidification time of the casting balls will seriously affect the internal forming quality of the casting balls.

[0003] The entire casting production line sequentially completes the processes of sand coating, mold closing, pouring, cooling, and demolding. The cast products require a certain solidification time. In batch casting production, the cooling area is limited, which restricts production efficiency. Therefore, the cast products are clamped and transferred to a separately set cooling line for cooling. Existing clamping devices have limited transfer capacity and cannot work in coordination with the casting production line and cooling line, resulting in relatively low line change efficiency. For example, patent CN203830710U discloses a cooling machine for iron mold sand coating casting. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a sand-coated slow-cooling line-changing device for iron molds, thereby achieving efficient cooling and line-changing for casting products.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: This application provides a slow cooling line changing device for iron mold sand coating production line, which is set up with a slow cooling line for continued cooling of casting products in the iron mold sand coating production line. The iron mold sand coating slow cooling line changing device is set up in association with the iron mold sand coating production line and the slow cooling line. The iron mold sand coating slow cooling line changing device includes a clamping mechanism that can smoothly transfer the casting products to the new line for continued cooling.

[0006] Further or preferred: The iron mold sand coating slow cooling line changing device includes a device frame, one part of which corresponds to the roller conveyor of the iron mold sand coating production line, and the other part of which corresponds to the operating area of ​​the slow cooling line.

[0007] The slow cooling line is equipped with a product slow cooling frame for storing the casting products for further cooling, and the device frame is equipped with a locking mechanism to lock the product slow cooling frame.

[0008] The product slow-cooling frame is suspended and runs on the slow-cooling line. The bottom of the product slow-cooling frame is equipped with a positioning rod, and the locking mechanism is a clamping structure used to hold the positioning rod.

[0009] The clamping structure includes a support, a locking drive cylinder mounted on the support, and a pair of locking arms. The support is fixed to the device frame, and the locking drive cylinder drives the pair of locking arms to move relative to each other.

[0010] The top of the device frame is a frame structure, and a reciprocating mechanism that can move horizontally is provided inside the frame structure. A lifting mechanism is provided on the reciprocating mechanism, and a clamping mechanism is located at the lower end of the lifting mechanism.

[0011] The reciprocating operating mechanism includes a translation vehicle, which is equipped with a reciprocating drive motor and a lifting drive motor. The frame structure is equipped with a horizontal rack, and the lifting mechanism is equipped with a vertical rack. The reciprocating drive motor is equipped with a horizontal drive gear that meshes with the horizontal rack, and the lifting drive motor is equipped with a lifting drive gear that meshes with the vertical rack.

[0012] The clamping mechanism includes a clamping mounting plate and a clamping drive cylinder, a pair of drive arms, and a pair of clamping arms mounted on the clamping mounting plate. The clamping mounting plate is fixed to the lower end of the lifting mechanism. The piston rod end of the clamping drive cylinder is hinged to one end of a pair of drive arms, and the other end of the drive arm is hinged to one end of the corresponding clamping arm. The other end of the pair of clamping arms forms a clamping end.

[0013] The clamping mounting plate and the pair of clamping arms are both horizontally arranged, and the pair of drive arms and the pair of clamping arms are both located below the clamping mounting plate.

[0014] Compared with the prior art, the present invention has the following advantages: The iron mold sand coating slow cooling line changing device has a reasonable structural design. It is associated with the cleaning part of the iron mold sand coating casting ball production line and the sand coating line circulation slow cooling line. The device's clamping mechanism can quickly transfer the casting products, that is, automatically clamp the products and place them smoothly on the product frame for continued cooling.

[0022] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0023] Although the invention has been shown and described herein with reference to specific embodiments, it is not intended to be limited to the details shown. Rather, various modifications in detail may be made within the equivalent scope and scope of the claims without departing from the invention. In the drawings, the same item numbers refer to the same elements.

[0024] Throughout this disclosure, various terms are used to describe the physical shape or arrangement of features. Many of these terms are used to describe features conforming to a cylindrical or generally cylindrical geometry with the feature as its radius and a central axis perpendicular to that radius. Unless otherwise specified, the terms are given the following meanings: The terms “longitudinal,” “longitudinal,” “axial,” and “axial” refer to a direction, dimension, or orientation parallel to the central axis. The terms “radial” and “radially” refer to a direction, dimension, or orientation perpendicular to the central axis. The terms “inward” and “inner” refer to a direction, dimension, or orientation extending radially toward the central axis. The terms “outward” and “outer” refer to a direction, dimension, or orientation extending radially away from the central axis.

[0025] In this specification, relative terms such as “horizontal,” “vertical,” “upward,” “downward,” “top,” and “bottom,” and their derivatives (e.g., “horizontal,” “downward,” “upward,” etc.) should be interpreted as referring to the direction described or the direction shown in the accompanying drawings. These relative terms are for ease of description and are not generally intended to require a specific direction.

[0026] Casting products on the casting production line require a certain cooling time; in batch casting production, the cooling area is limited, which restricts production efficiency; therefore, the casting products are picked up and transferred to a separately set cooling line for cooling; the existing picking device has limited transfer capacity and cannot work in coordination with the casting production line and cooling line, resulting in relatively low line changeover efficiency.

[0027] In response to the above technical problems, such as Figures 1 to 6 As shown, this application provides a slow cooling line changing device for iron mold sand coating production line, which is set up with a slow cooling line for the continued cooling of the casting products in the iron mold sand coating production line. The iron mold sand coating slow cooling line changing device is set up in association with the iron mold sand coating production line and the slow cooling line. The iron mold sand coating slow cooling line changing device includes a clamping mechanism that can smoothly transfer the casting products to the new line for continued cooling.

[0028] The main casting conveyor line does not require an extended cooling roller conveyor. The main line is mainly responsible for sand covering, mold closing, and pouring operations, effectively reducing the factory area occupied by the main production line and solving the problems of large footprint and reduced production efficiency of traditional cooling stations.

[0029] With the addition of the slow cooling line, the main production cycle is no longer limited by the cooling time of the cast balls. The main production line can continuously carry out casting operations in a cycle. The slow cooling line can buffer high-temperature cast balls in batches for sufficient cooling. Workers can flexibly control the dwell time on the slow cooling line according to the specifications of the cast balls to achieve controllable slow cooling. Its production efficiency is improved.

[0030] like Figure 1 As shown, the iron mold sand coating slow cooling line changing device includes a device frame 9. One part of the device frame 9 corresponds to the roller conveyor of the iron mold sand coating production line, and the other part of the device frame corresponds to the operating area of ​​the slow cooling line. The three are set up in conjunction and work together.

[0031] The roller conveyor 1 of the iron mold sand coating production line passes through the device frame 9, and another part of the device frame extends into the operating area of ​​the slow cooling line; the slow cooling line is equipped with a product slow cooling frame 7 for storing casting products for continued cooling, which facilitates the transfer of the casting balls 3 on the iron mold sand coating production line roller conveyor to the product slow cooling frame.

[0032] The slow cooling line includes a slow cooling line support 4, a circular track 5, and a suspension structure 6. The circular track is located below the top of the slow cooling line support, and the suspension structure is mounted on the circular track via a roller structure to enable cyclic movement. The top of the product slow cooling frame 7 is connected to the suspension structure.

[0033] The frame 9 connects to the main production line roller conveyor and the slow cooling line work area respectively. The frame spans the two conveyor lines and does not require a large area of ​​independent installation space. The main conveyor roller conveyor directly passes through the frame, and the frame extends partially into the slow cooling work area. This can reduce the transfer distance between the two production lines, shorten the travel distance for casting line change, and simplify the structural layout, making it convenient for on-site plant planning.

[0034] The frame enables the main production line roller conveyor, line changing device and slow cooling line to work together in a coordinated manner. After the casting is poured, it is transferred away from the main line by the clamping mechanism. The main line can carry out the pouring operation without interruption and will not be forced to stop and wait due to the cooling time of the high temperature casting. The slow cooling line buffers high temperature castings in batches. The production cycle does not interfere with each other and the overall production line operation efficiency is improved.

[0035] In some embodiments, such as Figures 2 to 4 As shown, the device frame 9 is equipped with a locking mechanism 8 to lock the product slow cooling frame, which prevents the product slow cooling frame from shaking when transferring the casting, and ensures stable and reliable transfer. The product slow-cooling frame is suspended and runs on the slow-cooling line. The bottom of the product slow-cooling frame is equipped with a positioning rod, and the locking mechanism is a clamping structure used to hold the positioning rod.

[0036] The clamping structure includes a support 801, a locking drive cylinder 802 mounted on the support, and a pair of locking arms. The support is fixed to the device frame, and the locking drive cylinder drives the pair of locking arms to move relative to each other.

[0037] Specifically, a pair of rotating shafts are arranged side by side on the support, and each rotating shaft has a gear at its end. The two gears at the ends of the pair of rotating shafts mesh with each other. One rotating shaft has a locking active arm 805, and the other rotating shaft has a locking driven arm 804. The locking active arm and the locking driven arm are aligned and opposite to each other. The piston rod end of the locking drive cylinder is hinged to the locking active arm. The locking active arm and the locking driven arm work together to clamp stably and reliably.

[0038] The locking mechanism is specifically designed to clamp and lock the bottom positioning rod, avoiding the high-temperature outer wall of the frame. The locking positioning reference is stable and reliable. The locking drive cylinder only needs to push the locking active arm, which drives the locking driven arm to swing synchronously in the opposite direction through the meshing end gears. The two locking arms move towards each other and the opening and closing strokes are consistent, and the clamping force is balanced. This can effectively prevent the frame from shifting or tilting on one side when the product is slowly cooled, and the frame is not easy to shake during the transfer of castings.

[0039] In some embodiments, such as Figure 6 As shown, the top of the device frame 9 is a frame structure, and a reciprocating mechanism 10 that can move horizontally is provided inside the frame structure. A lifting mechanism 11 is provided on the reciprocating mechanism, and a clamping mechanism is provided at the lower end of the lifting mechanism.

[0040] The reciprocating mechanism includes a translation car, which is equipped with a reciprocating drive motor 13 and a lifting drive motor 12. The frame structure is equipped with a horizontal rack 15 and a slide rail 14. The translation car can slide on the slide rail. The lifting mechanism is equipped with a vertical rack 16. The reciprocating drive motor is equipped with a horizontal drive gear that meshes with the horizontal rack, and the lifting drive motor is equipped with a lifting drive gear that meshes with the vertical rack.

[0041] The top of the device frame uses a frame structure to support the entire transfer assembly, with a compact and reasonable overall layout. The frame frees up the working space below and does not interfere with the lower roller conveyor or the slow-cooling frame conveyor path; the reciprocating mechanism is arranged in the upper part, and the clamping mechanism completes the gripping of castings from top to bottom, with a simple transfer path and saving installation space on the workshop floor.

[0042] The reciprocating drive motor drives the horizontal drive gear to mesh with the horizontal rack, thus driving the translation car to move precisely laterally; the lifting drive motor relies on the vertical rack to control the up and down movement of the clamping mechanism. The rack and gear meshing transmission eliminates slippage, the translation and lifting positions are controllable, the start and stop response is rapid, and it can accurately position the casting to the casting picking and unloading points, ensuring accurate clamping position for casting line changes.

[0043] The power components are centrally mounted on the translation vehicle, resulting in a high degree of equipment integration and facilitating automated control. The translation vehicle integrates two drive motors, allowing for independent operation of the translation and lifting actions. The gripping mechanism can be controlled separately for lateral reciprocating motion and vertical lifting, simplifying control.

[0044] In some embodiments, such as Figure 5 As shown, the clamping mechanism 2 includes a clamping mounting plate 201 and a clamping drive cylinder 202, a pair of drive arms 203 and a pair of clamping arms 204 disposed on the clamping mounting plate; the clamping mounting plate is fixed to the lower end of the lifting mechanism, the piston rod end of the clamping drive cylinder is hinged to one end of the pair of drive arms, the other end of the drive arm is hinged to one end of the corresponding clamping arm, and the other end of the pair of clamping arms forms a clamping end.

[0045] The clamping mounting plate and a pair of clamping arms are both horizontally positioned, and the pair of drive arms and the pair of clamping arms are both located below the clamping mounting plate.

[0046] The hinge positions are flexible, and the horizontal clamping arm is suitable for lateral clamping of castings. All components are integrated on a single clamping mounting plate, allowing for overall disassembly and maintenance. Different specifications of clamping arms can also be replaced to accommodate castings of various sizes. The structure is simple and reliable, and there are fewer potential failures in high-temperature environments.

[0047] The iron mold sand coating slow cooling line changing device of this application has a reasonable structural design. The slow cooling line changing device and the sand coating line circulation slow cooling line are set in conjunction with the part cleaning point of the iron mold sand coating casting ball production line. The device can quickly transfer the casting products through the clamping mechanism, that is, automatically clamp the products and place them smoothly on the product frame for continued cooling. All mechanisms work together to make the casting product cooling line changing highly efficient.

[0048] The above description is merely an illustration of preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0049] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
