Description

Technical Field

[0001] This utility model relates to the field of tooling equipment technology, and in particular to a spiral roller core-pulling tool. Background Technology

[0002] In the production of rubber spiral rollers, in addition to upper and lower molds, a mandrel is also required. The pre-formed material of the spiral roller is fitted onto the mandrel, and then the entire assembly is placed between the upper and lower molds for compression molding and vulcanization. After vulcanization, the mandrel and the spiral roller adhere together with strong adhesion, making separation difficult. Currently, the most common method is manual separation of the mandrel from the spiral roller. While simple, this method is labor-intensive, time-consuming, and results in high worker fatigue, low efficiency, and certain safety hazards. Utility Model Content

[0008] The spiral roller core-pulling fixture according to the embodiments of this utility model has at least the following beneficial effects:

[0009] In this embodiment, after the product is formed, the product spiral roller can be installed through the mounting position of the mounting part. The mounting part limits the spiral roller in a first direction, and then the limiting component is connected to the mandrel. The limiting component limits the mandrel in a first direction. Then, the mounting part is driven to move away from the limiting component by the driving device. Since the spiral roller and the mandrel are limited by the mounting part and the limiting component respectively, when the mounting part moves away from the limiting component, it can drive the spiral roller to move until it separates from the mandrel. Thus, the separation of the product spiral roller from the mandrel is realized. Compared with the traditional manual operation, it saves time and effort and has high work efficiency.

[0010] According to some embodiments of the present invention, the upper end face of the mounting part is provided with a downward recess to form the mounting position, and the two ends of the recess along the first direction are respectively provided with stop surfaces, which are perpendicular to the first direction and parallel to the vertical direction.

[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Therefore, they should not be construed as limitations on this utility model.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0043] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0044] In the production of rubber spiral rollers, in addition to upper and lower molds, a mandrel is also required. The pre-formed material of the spiral roller is fitted onto the mandrel, and then the entire assembly is placed between the upper and lower molds for compression molding and vulcanization. After vulcanization, the mandrel and the spiral roller adhere together with strong adhesion, making separation difficult. Currently, the most common method is manual separation of the mandrel from the spiral roller. While simple, this method is labor-intensive, time-consuming, and results in high worker fatigue, low efficiency, and certain safety hazards.

[0045] Based on this, the present invention proposes a spiral roller core-pulling tool, which can effectively improve the above-mentioned problems.

[0046] The following is a reference to the appendix. Figure 1 To be continued Figure 7 This invention describes a spiral roller core-pulling tool according to an embodiment of the present invention.

[0047] Reference Figure 1 and Figure 2 As shown, a spiral roller core-pulling fixture according to an embodiment of the present invention includes: an installation part 100, a limiting component 200, and a driving device 300.

[0048] The mounting part 100 defines a mounting position for mounting the spiral roller 10 and restricting the displacement of the spiral roller 10 relative to the mounting part 100 in a first direction. When the spiral roller 10 is mounted in the mounting position, the first direction is parallel to the axial direction of the spiral roller 10.

[0049] The limiting component 200 is used to connect with the spindle 20 and limit the displacement of the spindle 20 relative to the limiting component 200 in a first direction. Obviously, the limiting component 200 can disconnect from the spindle 20.

[0050] The drive unit 300 is connected to the mounting part 100 in a transmission manner. The drive unit 300 can drive the mounting part 100 to move away from the limiting component 200 in a first direction, so as to drive the spiral roller 10 to move until it separates from the spindle 20.

[0051] In this embodiment of the utility model, after the product is formed, the spiral roller 10 can be installed through the mounting position of the mounting part 100. The mounting part 100 limits the spiral roller 10 in a first direction. Then, the limiting component 200 is connected to the mandrel 20, and the limiting component 200 limits the mandrel 20 in a first direction. Then, the driving device 300 drives the mounting part 100 to move away from the limiting component 200. Since the spiral roller 10 and the mandrel 20 are limited by the mounting part 100 and the limiting component 200 respectively, when the mounting part 100 moves away from the limiting component 200, it can drive the spiral roller 10 to move until it separates from the mandrel 20. Thus, the separation of the product spiral roller 10 from the mandrel 20 is achieved. Compared with traditional manual operation, it saves time and effort and has high work efficiency.

[0052] Reference Figure 3 As shown, in some embodiments of this utility model, the upper end face of the mounting part 100 is provided with a downward recess 101 to form a mounting position. The two ends of the recess 101 along the first direction are respectively provided with stop surfaces 102. The stop surfaces 102 are perpendicular to the first direction and parallel to the vertical direction. With the above arrangement, as long as the spiral roller 10 is embedded in the recess 101, the relative positioning of the spiral roller 10 and the mounting part 100 in the first direction can be achieved. The structure is simple and practical.

[0053] It should be noted that multiple spiral rollers 10 may need to be formed on a single mandrel 20, therefore the recess 101 must be set in a one-to-one correspondence with the spiral rollers 10.

[0054] In addition, it is understandable that, referring to Figure 3 As shown, multiple sets of mounting positions can be spaced apart on the mounting section 100 along a second direction perpendicular to the first direction to facilitate the simultaneous separation of multiple sets of spiral rollers 10 and mandrels 20, thereby improving work efficiency. Of course, the limiting assembly 200 must meet the requirement of being able to connect to multiple mandrels 20 simultaneously.

[0055] Reference Figures 1 to 3 As shown, in some embodiments of this utility model, one end of the mandrel 20 is provided with a connecting hole 21; the limiting component 200 includes a mounting base 210 and a limiting rod 220. Multiple mounting bases 210 are provided, spaced apart along a second direction, and each mounting base 210 is provided with an insertion hole 211 extending along the second direction, which is perpendicular to the first direction; the limiting rod 220 is used to pass through the insertion hole 211 and the connecting hole 21 to connect with the mandrel 20. In use, after the product is formed, the product spiral roller 10 can be installed through the mounting position of the mounting part 100. The mounting part 100 limits the spiral roller 10 in the first direction. Then, the driving device 300 drives the mounting part 100 to move until the connecting hole 21 of the mandrel 20 is aligned with the insertion hole 211 of the mounting base 210. Then, the limiting rod 220 is inserted into the connecting hole 21 and the insertion hole 211 to realize the connection between the limiting rod 220 and the mandrel 20. Then, the driving device 300 drives the mounting part 100 to move away from the limiting component 200, causing the spiral roller 10 to move until it separates from the mandrel 20.

[0056] In this embodiment, by setting the limiting rod 220 and the insertion hole 211, it is easy to connect or separate from the mandrel 20. The structure is simple and the operation is very convenient, which can improve work efficiency.

[0057] In some specific embodiments, both the first direction and the second direction are horizontal. For example, the first direction may be the front-back direction, and the second direction may be the left-right direction.

[0058] In some specific embodiments, one end of the mandrel 20 is provided with an annular structure to form a connecting hole 21.

[0059] Reference Figure 3 As shown, in some embodiments of this utility model, the cross-sectional dimension of the insertion hole 211 is larger than the cross-sectional dimension of the limiting rod 220. This operation provides a certain amount of flexibility, making it easy for the limiting rod 220 to pass through both the insertion hole 211 and the connecting hole 21 at the same time.

[0060] Reference Figure 1 and Figure 2As shown, in some embodiments of this utility model, the spiral roller core-pulling fixture further includes a frame 400 and a movable seat 500; the frame 400 provides an installation and support carrier for each component; the movable seat 500 is disposed on the frame 400 and connected to the output end of the drive device 300, and the movable seat 500 can move along a first direction under the drive of the drive device 300; wherein, the mounting part 100 is mounted on the movable seat 500, for example, the mounting part 100 can be connected to the movable seat 500 by fasteners. In this embodiment, by setting the movable seat 500 as an intermediate part between the drive device 300 and the mounting part 100, the direct connection between the mounting part 100 and the drive device 300 is avoided, which can improve the convenience of maintenance and reduce maintenance costs.

[0061] In some embodiments, the mounting base 210 is mounted on the rack 400.

[0062] Reference Figure 4 As shown, in some embodiments of this utility model, the frame 400 is provided with a support platform 410, and the bottom of the movable seat 500 is rotatably provided with multiple rollers 510. The movable seat 500 is supported on the support platform 410 by the multiple rollers 510, that is, the outer peripheral wall of the rollers 510 is in contact with the support platform 410, and the rotation axis of the rollers 510 extends along the second direction. The second direction, the first direction, and the vertical direction are perpendicular to each other. In this embodiment, by providing rollers 510 at the bottom of the movable seat 500 and supporting it on the support platform 410 by the rollers 510, the movable seat 500 is provided with stable support on the one hand, and the friction force when the movable seat 500 moves can be reduced on the other hand.

[0063] It is conceivable that the roller 510 is detachably mounted on the movable seat 500; of course, the roller 510 can also be replaced by a wheel.

[0064] It is conceivable that the drive unit 300 can be a hydraulic cylinder, or of course, a pneumatic cylinder.

[0065] In some embodiments of this utility model, a guide component is provided between the frame 400 and the movable seat 500 to provide guidance for the movement of the movable seat 500 along the first direction, prevent the movable seat 500 from deviating during the movement, and ensure high reliability.

[0066] Reference Figure 1As shown, in some specific embodiments, the guide assembly includes two sets of guide wheels 420, which are respectively disposed on opposite sides of the frame 400 along the second direction. Each set of guide wheels 420 includes a plurality of guide wheels 420 spaced apart along the first direction. The guide wheels 420 are rotatably disposed on the frame 400, and the rotation axis of the guide wheels 420 extends vertically. The vertical direction, the first direction, and the second direction are perpendicular to each other. The outer peripheral wall of the guide wheel 420 is used to contact the side wall of the movable seat 500. By setting the guide wheels 420, not only can the movement of the movable seat 500 be guided, but the friction between the guide wheels and the movable seat 500 can also be reduced.

[0067] Reference Figures 1 to 3 As shown, in some embodiments of this utility model, the mounting part 100 is the lower mold for forming the spiral roller 10, and the aforementioned recess 101 is the lower cavity of the lower mold. Additionally, the lower mold is also provided with a groove for the mandrel 20 to be inserted. In this embodiment, using the lower mold for forming the spiral roller 10 as the mounting part 100 allows for direct separation of the spiral roller 10 and mandrel 20 after automatic demolding, eliminating the need to remove them for further separation and improving production efficiency. It should be noted that, to avoid interference, the limiting component 200 needs to be positioned away from the product processing location (i.e., the location where the mold forms the product). For example, Figure 7 The diagram shows the state of the spiral roller core-pulling tool in this embodiment when the lower mold is in the processing position.

[0068] Reference Figure 3 and Figure 7 As shown, in some embodiments of this utility model, the mounting part 100 (lower mold) is provided with a detachable stop part. When the spiral roller 10 is mounted in the mounting position and sleeved on the mandrel 20, the stop part can limit the upward displacement of the mandrel 20 relative to the mounting part 100 and avoid the movement path of the mandrel 20 relative to the mounting part 100 in the first direction. By providing the stop part, the product is prevented from being carried away from the lower mold by the upper mold when the equipment automatically ejects the mold.

[0069] In some specific embodiments, the mounting part 100 (lower mold) is provided with supports 110 at both ends along the first direction. The supports 110 are provided with mounting holes that extend along the second direction. The stop part is provided with a stop rod 120 that passes through the mounting hole, making it easy to assemble and disassemble.

[0070] The following describes the operation process of a spiral roller core-pulling tooling according to an embodiment of the present invention, taking the mounting part 100 as the lower mold of the forming spiral roller 10 as an example.

[0071] When loading materials, refer to Figure 5 and Figure 6First, a pre-formed material 30 (for forming the spiral roller 10) is fitted onto the mandrel 20. Then, the connecting hole 21 of the mandrel 20 is aligned with the insertion hole 211 on the mounting base 210, and the mandrel 20 is positioned on the side of the mounting base 210 away from the mounting part 100 (lower mold). Then, a limiting rod 220 is inserted. Then, the moving seat 500 is driven to move close to the mounting base 210 to the set position by the driving device 300. The stop rod 120 is removed, and the mandrel 20 is rotated around the limiting rod 220 to install the pre-formed material 30 on the mandrel 20 onto the mounting part 100. Then, the limiting rod 220 is removed and the stop rod 120 is installed. The mounting part 100 (lower mold) is driven to move to the processing position by the driving device 300 for mold closing processing.

[0072] After molding, the equipment automatically ejects the mold. Then, the drive device 300 drives the moving seat 500 to move until the connecting hole 21 on the mandrel 20 is aligned with the insertion hole 211 on the mounting seat 210. Then, the limiting rod 220 is inserted. Finally, the drive device 300 drives the moving seat 500 to move away from the limiting rod 220 so that the spiral roller 10 is separated from the mandrel 20.
