Description

Technical Field

[0001] This invention relates to the technical field of shipbuilding, specifically to a combination mold for a rib cold bending machine, and more particularly to a combination mold applicable to different types of rib cold bending machines. Background Technology

[0002] In existing technology, during rib cold bending machine processing, the two ends of the rib to be bent rest on the side dies, and the middle rests on the middle die. When the middle die is stressed, the rib bends and deforms under the support of the side dies. During the bending process, the rib is close to the side die heads at both ends and the middle die head in the middle, thus forming a three-point support pattern. Currently, a single die is used for bulb flats, angle steel, and T-shaped steel. Different dies must be used to bend different profiles, thus limiting the type and size range of ribs. To accommodate different types and sizes of ribs, the entire set of dies must be changed, which is time-consuming and labor-intensive.

[0003] In addition, the commonly used molds currently lack detection functions, making it impossible to effectively control the feed rate of the ribs and prevent jamming.

[0004] Therefore, how to design a modular mold with detection function and easy mold head replacement is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide an improved combination mold for a rib cold bending machine. Through improvements to the middle mold and the side mold, the middle mold head and the side mold head in the mold combination can be easily disassembled and replaced to suit the needs of different rib models, thus having a wide range of applications. At the same time, it can detect the feed amount of the rib to prevent jamming.

[0006] To achieve the above objectives, the technical solution of the present invention is: a combined mold for a rib cold bending machine, comprising a middle mold and a set of side molds that cooperate with the middle mold, characterized in that: the middle mold includes a middle mold base and a middle mold head that is detachably connected to the middle mold base, the middle mold head can be reversed in direction during installation, a set of springs and a set of proximity sensors are provided between the middle mold head and the middle mold base, and an adjustment mechanism is provided at one end of the middle mold head to adjust the extension amount of the springs; the side molds include a side mold base, the side mold base is provided with a side mold head mounting groove, a detachable side mold head is provided on one side of the side mold head mounting groove, the side mold head can be reversed in direction during installation, and a support block that cooperates with the side mold head is provided on the other side.

[0007] Preferably, the adjustment mechanism includes a connecting block with two fixing holes and one adjustment hole. The fixing holes are provided with fixing bolts, and the adjustment mechanism is fixedly connected to the middle mold base through the fixing bolts. The adjustment hole is provided with an adjustable bolt. The shape of the connecting block matches the end of the middle mold head. Rotating the adjustment bolt can adjust the amount by which the end of the middle mold head extends beyond the end of the middle mold base.

[0008] Preferably, a middle mold side plate is provided on one side of the middle mold base, a middle mold head mounting cavity is provided on the lower side of the middle mold base, and a middle mold side plate auxiliary plate that matches the shape of the middle mold head is provided on the top of the middle mold head mounting cavity. The middle mold side plate auxiliary plate and the middle mold base are fixedly connected by auxiliary plate bolts.

[0009] Furthermore, one side of the middle mold head is a connecting surface, and the other side is an outwardly bulging arc-shaped working surface. The connecting surface is used to connect with the middle mold base. A spring setting groove is provided in the middle of the connecting surface. A sensor working groove that cooperates with the proximity sensor is provided at both ends of the spring setting groove. One end of the proximity sensor is fixedly connected to the middle mold base, and the other end extends into the sensor working groove. The upper side of the working surface is rounded and the lower side is beveled.

[0010] Furthermore, one end of the intermediate mold head has an adjustment setting groove that cooperates with the adjustment mechanism. The adjustment mechanism is locked in the adjustment setting groove. A blocking block is provided at the bottom of the adjustment setting groove. The adjustable bolt abuts against the blocking block. By rotating the adjusting bolt, the blocking block can be moved. The blocking block is fixedly connected to the intermediate mold head.

[0011] Furthermore, the side mold head is fixedly connected to the side mold head mounting groove via side mold bolts set within the side mold head mounting groove. The working surface of the side mold head corresponds to the support block, and the working surface is a convex arc shape. The upper side edge of the working surface is rounded, and the lower side edge is beveled.

[0012] Compared with the prior art, the technical solution of the present invention not only improves the overall technical solution, but also includes many improvements in details. Specifically, it has the following beneficial effects:

[0013] 1. The improved solution of the present invention includes a middle mold base and a middle mold head that are detachably connected to the middle mold base. The middle mold head can be reversed in direction during installation. The side mold is provided with a detachable side mold head, which can also be reversed in direction during installation. The side mold head and the middle mold head can be easily replaced to adapt to different types of rib processing needs. At the same time, the mold head can be reversed in direction during installation, which makes it more compatible with the type of rib. One mold head can provide two modes of fitting with the rib, which is versatile and has a wide range of applications.

[0014] 2. In the technical solution of the present invention, a set of springs and a set of proximity sensors are provided between the middle mold head and the middle mold base. One end of the middle mold head is provided with an adjustment mechanism to adjust the extension amount of the spring. The movement variable of the middle mold head being pressed in by the rib can be directly measured by the proximity sensor, thereby controlling the rib processing speed and preventing jamming.

[0015] 3. In the structure of the present invention, the adjustment mechanism is fixedly connected to the middle mold base by a fixing bolt. An adjustable bolt is provided in the adjustment hole. By rotating the adjusting bolt, the extension of the end of the middle mold head relative to the end of the middle mold base can be adjusted. This allows for a more appropriate pressing force in terms of angle and strength to be applied to the rib during the rib processing, ensuring the pressing effect of the rib, making it faster, more efficient, and with a high yield.

[0016] 4. This invention has a simple structure, is easy to operate, and has a wide range of applications. It can adjust the force points when pressing the ribs, making the curvature of the pressed ribs more natural, less prone to breakage, and resulting in a higher yield. Attached Figure Description

[0051] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] This invention provides a combined mold for a rib cold bending machine, see details below. Figure 1 The invention includes a central mold and a set of side molds that cooperate with the central mold. Its difference from existing technologies lies in the following: the central mold includes a central mold base and a central mold head that is detachably connected to the central mold base. The central mold head can be reversed in direction during installation. A set of springs and a set of proximity sensors are provided between the central mold head and the central mold base. The proximity sensors can detect the distance the central mold head is pressed in in real time. One end of the central mold head is provided with an adjustment mechanism to adjust the extension of the springs. The side molds include a side mold base with a side mold head mounting groove. A detachable side mold head is provided on one side of the side mold head mounting groove, and the side mold head can be reversed in direction during installation. A support block that cooperates with the side mold head is provided on the other side.

[0053] In use, two side molds are positioned on either side of the central mold. The ribs to be processed are held within the central and side molds. The central mold provides an upward lifting force, while the side molds provide a downward pressing force. Through their combined action, the ribs are bent to the required bending angle. Since both the central and side mold heads used in this invention are easily disassembled, different mold heads can be used to process different types of ribs, resulting in a wide range of applications. This also ensures better fit with the ribs, facilitating rib shaping. Furthermore, each central or side mold head can be reversed in orientation. Due to the different chamfer settings on the upper and lower sides, the magnitude and point of force applied to the ribs differ, resulting in a more precise pressing effect and ensuring optimal rib bending.

[0054] Example 1

[0055] In the technical solution described in this embodiment, a central mold 20 and two side molds 19 are provided. The central mold 20 includes a central mold base 7 and a central mold head 15 detachably connected to the central mold base. The central mold head can be reversed in direction during installation, and one central mold head can provide two different external chamfer forms to meet the pressing requirements of the ribs. A set of springs 10 and a set of proximity sensors 9 are provided between the central mold head and the central mold base. The proximity sensors can detect the distance variable of the central mold head being pressed in in real time. An adjustment mechanism 11 is provided at one end of the central mold head to adjust the springs. The extension amount; the side mold 19 includes a side mold base 1, on which a side mold head mounting groove is provided. A detachable side mold head 4 is provided on one side of the side mold head mounting groove. The side mold head can be reversed in the up and down direction during installation. By reversing the installation direction, one side mold head can provide two different external chamfer forms to meet the pressing needs of the rib. The other side is provided with a support block 3 that cooperates with the side mold head. The support block cooperates with the side mold head to better bend the two ends of the rib, ensure the bending angle, and minimize the damage to the rib during the pressing process.

[0056] In a specific embodiment, the adjustment mechanism 11 includes a connecting block 12, which has two fixing holes and one adjustment hole. The fixing holes are provided with fixing bolts 14. The adjustment mechanism is fixedly connected to the middle mold base 7 through the fixing bolts 14. The adjustment hole is provided with an adjustable bolt 13. The shape of the connecting block 12 matches the end of the middle mold head 15. Rotating the adjustment bolt will push the middle mold head to move along the middle mold head mounting cavity on the lower side of the middle mold base, which can adjust the amount of extension of the end of the middle mold head relative to the end of the middle mold base.

[0057] Furthermore, a middle mold side plate 6 is provided on one side of the middle mold base. The middle mold side plate can increase the distance between the middle mold and the middle mold auxiliary mold, thus making it more suitable for processing ribs of different types and sizes. A middle mold head mounting cavity is provided on the lower side of the middle mold base. A middle mold side plate auxiliary plate 17 that matches the shape of the middle mold head is provided on the top of the middle mold head mounting cavity. The middle mold side plate auxiliary plate 17 is fixedly connected to the middle mold base by three evenly distributed auxiliary plate bolts 8.

[0058] Furthermore, one side of the intermediate mold head 15 is a connecting surface, and the other side is an outwardly bulging arc-shaped working surface. This arc-shaped working surface directly cooperates with the rib, providing support for the middle part of the rib. The connecting surface is used to connect with the intermediate mold base 7. A spring setting groove 16 is provided in the middle of the connecting surface. A sensor working groove 18 that cooperates with a proximity sensor is provided at both ends of the spring setting groove 16. One end of the proximity sensor 9 is fixedly connected to the intermediate mold base, and the other end extends into the sensor working groove 18. Here, the proximity sensor 9 can measure the displacement value of the intermediate mold head being pressed in by the middle of the rib in real time, so as to determine whether the pressing speed is reasonable and whether there is a risk of jamming (when the displacement value displayed by the proximity sensor 9 remains unchanged, it is judged to be jamming). The upper side of the working surface is rounded and the lower side is beveled. The beveled angle of the lower side is 45-65 degrees, with a preferred value of 60 degrees. When the mold head flips up and down for assembly, it can be applied to ribs 5 with different shapes and structures, and better fits the outer surface of the rib 5, ensuring the effect and precision of rib processing.

[0059] Meanwhile, one end of the middle mold head 15 is fitted with an adjustment setting groove that cooperates with the adjustment mechanism. The adjustment mechanism is locked in the adjustment setting groove. The inner side of the adjustment setting groove cooperates with the adjustable bolt. This inner side is a blocking slope. The angle between the blocking slope and the inner side of the middle mold head is 10-20 degrees. By rotating the adjustment bolt, the blocking slope can be pushed, which in turn pushes the middle mold head to make a fine adjustment displacement along the middle mold head mounting cavity. This can effectively adjust the extension amount of the outer part of the middle mold relative to the outer part of the middle mold seat, thereby adjusting the extension amount of the spring.

[0060] Furthermore, the side mold head 4 is fixedly connected to the side mold head mounting groove by side mold bolts 2 set in the side mold head mounting groove. The working surface of the side mold head is correspondingly set with the support block. The working surface is a convex arc shape, with a rounded chamfer on the upper side and a beveled angle on the lower side, with a bevel angle of 40-70 degrees, preferably 65 degrees. Inside the side mold head mounting groove, the inner surface corresponding to the support block is an arc surface. The function of the support block 3 is to support both ends of the rib and ensure the rigidity of the rib in the vertical direction during bending.

[0061] Example 2

[0062] The specific embodiments of the present invention are as follows:

[0063] The connection relationships involved in the side mold are as follows: the side mold base 1 is fixedly connected to the side mold head 4 through the side mold bolt 2, and the side mold base 1 is fixedly connected to the support block 3.

[0064] The connection relationships involved in the middle mold are as follows: the middle mold side plate 6 is fixedly connected to the middle mold base 7; the middle mold base 7 is fixedly connected to the middle mold side plate auxiliary plate 17 through the auxiliary plate bolt 8; the proximity sensor 9 is fixedly connected to the middle mold head 15; one end of the spring 10 is fixedly connected to the middle mold base 7, and the other end is fixedly connected to the middle mold head 15; in the adjustment mechanism 11, the connecting block 12 is fixedly connected to the middle mold base 7 through the fixing bolt 14, and the connecting block 12 is fixedly connected to the middle mold head 15 through the adjustable bolt 13.

[0065] The specific steps for using this invention are as follows:

[0066] 1. For example Figure 1 As shown, the two ends of the rib to be bent rest on the side molds, and the middle rests on the middle mold. When the middle mold is subjected to force, the rib bends and deforms under the support of the side molds. During the bending process, the rib is in close contact with the side mold head 4 of the side mold and the middle mold head 15 of the middle mold.

[0067] 2. Depending on the type (e.g., T-profile, bulb flat, angle steel, etc.) and size of the ribs, the side die head 4 and the middle die head 15 can be manually replaced, as shown in section 2. Figure 3 , Figure 10 as well as Figure 11 As shown;

[0068] 3. The side mold head 4 and the middle mold head 15 are asymmetrical, with rounded corners on the top and chamfered corners on the bottom, as shown below. Figure 5 , Figure 6 , Figure 12 as well as Figure 13 As shown, this allows the installation direction of the side mold head 4 and the middle mold head 15 to be changed, thereby adapting to different types and sizes of ribs;

[0069] 4. The support block 3 in the side mold can support both ends of the rib, ensuring the rigidity of the rib in the vertical direction during bending;

[0070] 5. Inside the intermediate mold, there is an elongated hole between the adjustable bolt 13 and the connecting block 12. Therefore, by adjusting the installation position of the adjustable bolt 13, the position of the intermediate mold head 15 can be adjusted, thereby adjusting the extension amount of the spring 10.

[0071] 6. Inside the intermediate mold, the proximity sensor 9 can sense the displacement of the intermediate mold head 15 as it is pressed in by the ribs, and thus send a signal to the control unit to adjust the feed speed of the ribs. If the displacement of the intermediate mold head 15 as it is pressed in by the ribs is too large, there is a risk of jamming. At this time, the proximity sensor 9 sends a signal to the control unit to adjust the feed speed of the ribs.

[0072] 7. After removing the side plate 6 of the middle mold, the size of the middle mold and its auxiliary mold (such as...) can be increased. Figure 1The distance between (as shown) is adjusted to accommodate different types and sizes of ribs.

[0073] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
