Description

Technical Field

[0001] The utility model relates to the technical field of inclined wedge moulds, in particular to an inclined wedge mechanism. Background Art

[0002] The inclined wedge mechanism is a mechanism used for stamping processing. Due to the complex and changeable shapes of the workpiece, it is impossible to achieve complete processing in the same direction. Sometimes when the work content is at a certain angle to the stamping direction of the overall mold, the workpiece cannot be directly processed and formed. It is necessary to use an inclined wedge mechanism to change the force in the stamping direction and convert the vertical force into a force at a certain angle to the stamping direction, thereby facilitating the processing and manufacturing of the workpiece.

[0003] In order to increase the stability of the sliding cooperation with the slider, the existing inclined wedge mechanism generally restricts the slider to the outside while maintaining a sliding connection with the slider. It is inconvenient to remove the slider after it is installed on the outside of the inclined wedge. When the slider or the inclined wedge is damaged or worn, it is affected by the connection of another structure, which makes it inconvenient to perform maintenance, repair and other operations, which is very inconvenient. Utility Model Content

[0022] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] See also Figure 1-4 The utility model discloses an inclined wedge mechanism, comprising an inclined wedge 1, a guide sleeve 2 installed on the inner side of the inclined wedge 1, and a slider 9 installed on the outer side of the guide sleeve 2. Threaded holes 12 are arranged at both ends of the inner side of the inclined wedge 1, and threaded tracks are arranged at both ends of the inner side of the guide sleeve 2. The two threaded tracks are arranged in reverse directions. A first threaded member and a second threaded member connecting the two threaded holes 12 are respectively installed in the two threaded tracks. A transmission structure engaging the first threaded member and the second threaded member is installed in the guide sleeve 2. The transmission structure controls the first threaded member and the second threaded member to move in opposite directions at the same time by rotating, and simultaneously performs extension and contraction adjustment along the threaded tracks.

[0025] See also Figure 2A movable groove 11 is provided on the outer side of the inclined wedge 1, and threaded holes 12 are opened in the center of both ends of the inner wall of the movable groove 11, one of the threaded holes 12 passes through the inclined wedge 1. The setting of the threaded hole 12 passing through the inclined wedge 1 makes it convenient for the staff to control the second threaded sleeve 4 by connecting the installation groove 8 through a tool.

[0026] See also Figure 4 The guide sleeve 2 is installed between the two ends of the inner wall of the movable groove 11. A through hole 21 is arranged in the center of both ends of the guide sleeve 2. The diameter of the through hole 21 is smaller than the diameter of the inner side of the guide sleeve 2. The setting of the through hole 21 can allow the first thread head 31 and the second thread head 41 to pass through and extend to the outside of the guide sleeve 2 for connection, and can also limit the first thread sleeve 3 and the second thread sleeve 4 to prevent them from moving and falling off from the guide sleeve 2. A spacer ring 22 is arranged in the center of the inner side of the guide sleeve 2. The thread track is composed of a first thread groove 23 and a second thread groove 24. The first thread groove The first thread groove 23 and the second thread groove 24 are respectively arranged between one end of the inner wall of the guide sleeve 2 and the spacer ring 22. The first thread groove 23 and the second thread groove 24 are arranged in reverse direction and have the same rotation direction as the adjacent threaded hole 12. The reverse arrangement of the first thread groove 23 and the second thread groove 24 limits the rotational activity direction of the first threaded sleeve 3 and the second threaded sleeve 4. When the first threaded sleeve 3 and the second threaded sleeve 4 rotate in the same direction, the first threaded sleeve 3 and the second threaded sleeve 4 will move in opposite directions, thereby cooperating with the guide sleeve 2 and the threaded hole 12 to be stored and installed at the same time.

[0027] See also Figure 3 The first threaded member is composed of a first threaded sleeve 3 and a first threaded head 31. The first threaded sleeve 3 is installed in the first threaded groove 23. The first threaded head 31 is arranged at the center of the end of the first threaded sleeve 3 away from the spacer ring 22 and passes through the through hole 21. The first threaded head 31 is threadedly connected with the threaded hole 12 near the first threaded groove 23. The second threaded member is composed of a second threaded sleeve 4 and a second threaded head 41. The second threaded sleeve 4 is installed in the second threaded groove 24. The second threaded head 41 is arranged at the center of the end of the second threaded sleeve 4 away from the spacer ring 22 and passes through the through hole 21. The second threaded head 41 is threadedly connected with the threaded hole 12 near the second threaded groove 2 The first thread head 31 and the second thread head 41 have the same thread direction as the first thread sleeve 3 and the second thread sleeve 4. The first thread sleeve 3 and the second thread sleeve 4 can be connected or connected to the threaded holes 12 with the same thread direction through the first thread head 31 and the second thread head 41 at one end during the rotation along the first thread groove 23 and the second thread groove 24, saving operation steps and having a fixing effect on the guide sleeve 2. The first thread head 31 and the second thread head 41 can also be separated from the connected threaded holes 12 during the rotation of the first thread sleeve 3 and the second thread sleeve 4.

[0028] See also Figure 4The first threaded sleeve 3 and the second threaded sleeve 4 are both provided with a tooth groove 5 in the center of one end close to each other, and the first threaded sleeve 3 and the second threaded sleeve 4 are both provided with a regular hexagonal installation groove 8 in the center of one end away from each other. The installation groove 8 is convenient for the staff to control the second threaded sleeve 4 or the first threaded sleeve 3 to rotate through props such as a wrench. The transmission structure is composed of a rotating shaft 6 and a gear 7. The rotating shaft 6 is installed on the inner side of the spacer ring 22, and the gear 7 is installed at both ends of the rotating shaft 6 and meshes with the tooth grooves 5 of the first threaded sleeve 3 and the second threaded sleeve 4. When the staff controls the second threaded sleeve 4 to rotate and move along the second threaded groove 24, the second threaded sleeve 4 can mesh with the gear 7 through the inner tooth groove 5 to drive the gear 7 to rotate. When the wheel 7 rotates, the gear 7 engages with the tooth groove 5 on the inner side of the first threaded sleeve 3, driving the first threaded sleeve 3 to rotate and move in the first threaded groove 23. When the first threaded sleeve 3 and the second threaded sleeve 4 rotate on the outside of the gear 7, they will move vertically without conflicting with the gear 7. Affected by the opposite directions of the first threaded groove 23 and the second threaded groove 24, when the first threaded sleeve 3 and the second threaded sleeve 4 rotate in the same direction, the first threaded sleeve 3 and the second threaded sleeve 4 will move toward the threaded hole 12 at the same time or move toward the spacer ring 22 at the same time, which makes it convenient for the first threaded sleeve 3 and the second threaded sleeve 4 to be connected and fixed to the threaded hole 12 at the same time, or to be simultaneously received in the guide sleeve 2 and disassembled with the wedge 1 for removal.

[0029] When it is necessary to remove the slider 9, first connect the mounting groove 8 at one end of the second threaded head 41 with a wrench, and control the second threaded sleeve 4 to rotate. The second threaded sleeve 4 can drive the gear 7 and the rotating shaft 6 to rotate through the meshing of the inner tooth groove 5 with the gear 7. The gear 7 drives the first threaded sleeve 3 to rotate and move in the first thread groove 23 through the meshing of the inner tooth groove 5 with the first threaded sleeve 3. Affected by the different thread directions of the first thread groove 23 and the second thread groove 24, the first threaded sleeve 3 and the second threaded sleeve 4 will move toward the spacer ring 22 at the same time. During the process, the first threaded sleeve 3 and the second threaded sleeve 4 move vertically on the outside of the tooth block. The first threaded head 31 and the second threaded head 41 at one end of the first threaded sleeve 3 and the second threaded sleeve 4 will also be separated from the threaded hole 12 with the same thread direction during the rotation process until the first threaded sleeve 3, the second threaded sleeve 4, the first threaded head 31 and the second threaded head 41 are completely received in the guide sleeve 2. At this time, the guide sleeve 2 loses its connection and fixation with the inclined wedge 1, and the slider 9 can be removed.
