Description

Technical Field

[0001] This utility model relates to the field of solid wheel spoke plate stamping die technology, and more specifically, this utility model relates to an anti-deformation die for wheel spoke stamping. Background Technology

[0002] Wheel spokes are devices that protect the wheel rims and spokes of a vehicle. In the processing of solid wheel spoke plates, stamping dies are used to stamp them. However, after a long period of use, the upper die head in the die will wear out. When the die head wears out, it will affect the quality of the solid wheel spoke plates and the die head needs to be replaced. However, the connection between the existing upper die and the die head is relatively complex, making the replacement operation difficult and not quick, thus affecting the processing efficiency.

[0003] To address the aforementioned issues, patent document publication number CN222607744U discloses a solid spoke plate stamping die, comprising a base, a top plate at the top of the support column, a hydraulic cylinder on the top plate, a fixing plate at the bottom of the hydraulic cylinder, a connecting seat at the bottom of the fixing plate connected by a fixing member, an upper die at the bottom of the connecting seat, a connecting groove at the bottom of the upper die, and a die head slidably mounted on the inner wall of the connecting groove.

[0004] However, it still has some drawbacks in actual use. For example, when changing the mold head, the device requires "firmly gripping the U-shaped rod and the connecting rod" and performing multiple steps (pressing down the connecting rod, pulling the U-shaped rod, changing the mold head, and releasing the connecting rod). The process is cumbersome and requires coordination of both hands. It is easy to make mistakes in noisy factory environments, which reduces the practicality of the device to some extent. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a deformation-resistant mold for wheel spoke stamping, so as to solve the problem that the mold head replacement process of the prior art is still inconvenient.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a deformation-resistant mold for wheel spoke stamping, comprising a top plate, a hydraulic cylinder being disposed on the top of the top plate, a fixing plate being fixedly connected to the output end of the hydraulic cylinder, and a connecting seat being disposed at the bottom of the fixing plate; the deformation-resistant mold for wheel spoke stamping further includes...

[0007] The upper mold is fixedly installed at the bottom of the connecting seat. A mold head is detachably installed at the bottom of the upper mold. The left and right sides of the mold head are provided with fixing grooves.

[0008] A rotating sleeve is rotatably mounted on the outer wall of the bottom of the connecting seat. The inner wall of the rotating sleeve is provided with a rough surface structure, and a ring gear is fixedly mounted on the surface of the rotating sleeve.

[0009] Connecting column one, which is slidably mounted on the top surface of the upper mold, has a rack on one side in the width direction, and the outer edge of the rack meshes with the outer edge of the ring gear;

[0010] The mounting block is fixedly installed on one side of the connecting column along its length. A movable plate is provided on the surface of the mounting block opposite to the connecting column. The top of the movable plate is in contact with the top surface of the upper mold. A snap-fit ​​plate is fixedly connected to the bottom of the movable plate. The snap-fit ​​plate passes through the side wall of the upper mold and snaps into the inside of the fixing groove.

[0011] It also includes fastening components, which are disposed opposite to each other on the left and right sides of the upper mold.

[0012] The fastening assembly includes a fixed rod, a movable column, a spring, a second connecting column, a torsion spring, a mounting end, a column, and a fastening roller. The fixed rod is fixedly installed on the inner wall of the upper mold side. The movable column is movably installed on the surface of the fixed rod, with the side of the movable column fitting against the inner wall of the upper mold. The spring is movably sleeved on the outside of the fixed rod, with its top end fixedly connected to the top of the fixed rod and its bottom end fixedly connected to the top surface of the movable column. The second connecting column is located on one side along the length of the movable column. One end of the torsion spring is fixedly connected to the inside of the end of the second connecting column, and the other end of the torsion spring is fixedly connected to the inside of the mounting end. The inner wall of the mounting end is rotatably connected to the outside of the end of the second connecting column. The fastening roller is fixedly connected to the surface of the mounting end via the column, and the surface of the fastening roller abuts against the top of the movable plate.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] In the above scheme, when disassembling the mold head, the rotating sleeve set outside the connecting seat is manually rotated, so that the ring gear installed on the surface of the rotating sleeve rotates synchronously. Through the meshing of the ring gear and the rack, the two connecting columns connected to the two racks can move towards each other on the top surface of the upper mold, thereby driving the two moving plates to move to the left and right sides of the upper mold respectively. At this time, the snap-fit ​​plate set on the surface of the moving plate moves synchronously and disengages from the fixing groove on the side of the mold head. Then the mold head can be moved horizontally out of the upper mold, thus completing the disassembly of the upper mold. This simplifies the transmission structure set in the original device. The snap-fit ​​plate can be separated from the fixing groove by the meshing transmission of the ring gear and the two racks, so as to disassemble the mold head. This reduces the cumbersomeness of the disassembly process, eliminates the need for coordinated operation of both hands, and improves the practicality of the device.

[0015] After the snap-fit ​​plate is snapped and fixed to the mold head, the column is deflected at a certain angle around the mounting end. At this time, the torsion spring set between the connecting column and the mounting end deforms, and the fastening roller rotates to a vertical angle and is located at the top of the moving plate. Then, the elastic structure of the spring drives the movable column to move down, so that the fastening roller moves down synchronously and abuts against the top of the moving plate. At this time, the torsion spring returns to its original deformation and provides force to the fastening roller, so that the fastening roller abuts against the top of the moving plate more tightly. Thus, while simplifying the transmission structure, it can also ensure the fastening of the moving plate and avoid the mold head from being accidentally deviated, which would cause uneven force on the mold and deformation.

[0022] As attached Figure 1 To be continued Figure 3 An embodiment of this utility model provides an anti-deformation mold for wheel spoke stamping, including a top plate 1, a hydraulic cylinder 2 disposed on the top of the top plate 1, a fixed plate 3 fixedly connected to the output end of the hydraulic cylinder 2, and a connecting seat 4 disposed at the bottom of the fixed plate 3. The anti-deformation mold for wheel spoke stamping also includes...

[0023] The upper mold 6 is fixedly installed at the bottom of the connecting seat 4. The bottom of the upper mold 6 is detachably equipped with a mold head 7. The left and right sides of the mold head 7 are provided with fixing grooves 8.

[0024] Rotary sleeve 9 is rotatably mounted on the outer wall of the bottom of the connecting seat 4. The inner wall of the rotating sleeve 9 is set with a rough surface structure. A ring gear 10 is fixedly mounted on the surface of the rotating sleeve 9. The ring gear 10 is set with a hollow ring structure so that it can be sleeved on the surface of the rotating sleeve 9. It is an existing structure. Due to the rough surface structure of its inner wall, the rotating sleeve 9 has a large frictional force with the connecting seat 4 during rotation. The frictional force can also fix the snap-fit ​​plate 15 that is snapped with the die head 7, so as to prevent it from moving accidentally during the operation of the equipment.

[0025] Connecting post 11 is slidably mounted on the top surface of the upper mold 6. A rack 12 is provided on one side of the connecting post 11 in the width direction. The outer edge of the rack 12 meshes with the outer edge of the ring gear 10.

[0026] Mounting block 13 is fixedly installed on one side of the connecting column 11 along its length. A movable plate 14 is provided on the side of the mounting block 13 opposite to the connecting column 11. The top of the movable plate 14 is in contact with the top surface of the upper mold 6. A snap-fit ​​plate 15 is fixedly connected to the bottom of the movable plate 14. The snap-fit ​​plate 15 passes through the side wall of the upper mold 6 and snaps into the inside of the fixing groove 8.

[0027] It also includes a fastening assembly 16, which is disposed opposite to the left and right sides of the upper mold 6.

[0028] The fastening assembly 16 includes a fixed rod 161, a movable column 162, a spring 163, a connecting column 164, a torsion spring 165, a mounting end 166, a column 167, and a fastening roller 168. The fixed rod 161 is fixedly installed on the inner wall of the side of the upper mold 6. The movable column 162 is movably installed on the surface of the fixed rod 161, with its side fitting against the inner wall of the upper mold 6. The spring 163 is movably sleeved on the outside of the fixed rod 161, with its top end fixedly connected to the top of the fixed rod 161 and its bottom end fixedly connected to the top surface of the movable column 162. The connecting column 164 is located on one side of the movable column 162 along its length. The torsion spring 165... One end of 5 is fixedly connected to the inside of the end of the connecting column 164, and the other end of the torsion spring 165 is fixedly connected to the inside of the mounting end 166. The inner wall of the mounting end 166 is rotatably connected to the outside of the end of the connecting column 164. The fastening roller 168 is fixedly connected to the surface of the mounting end 166 through the column 167. The surface of the fastening roller 168 abuts against the top of the moving plate 14. Through the torsion spring 165, it can apply a steering force to the column 167, so that when the fastening roller 168 abuts against the top of the moving plate 14, it provides a horizontal pushing force to the moving plate 14, thereby cooperating with the friction between the rotating sleeve 9 and the connecting seat 4 to further fasten the snap-fit ​​plate 15.

[0029] The working process of this utility model is as follows: When disassembling the mold head 7, the rotating sleeve 9 set outside the connecting seat 4 is rotated manually, so that the ring gear 10 installed on the surface of the rotating sleeve 9 rotates synchronously. Through the meshing of the ring gear 10 and the rack 12, the two connecting columns 11 connected to the two racks 12 respectively can move towards each other on the top surface of the upper mold 6, thereby driving the two moving plates 14 to move to the left and right sides of the upper mold 6 respectively. At this time, the snap-fit ​​plate 15 set on the surface of the moving plate 14 moves synchronously and disengages from the fixing groove 8 on the side of the mold head 7. Then the mold head 7 can be moved horizontally out of the upper mold 6, thus completing the disassembly of the upper mold 6.
