Description

Technical Field

[0001] This utility model belongs to the field of high-precision roller bearing outer ring production technology, and in particular relates to a stamping forming device for producing high-precision roller bearing outer rings. Background Technology

[0002] The stamping forming device for producing high-precision roller bearing outer rings is a key piece of equipment specifically designed for manufacturing high-precision, high-strength bearing outer rings through stamping processes.

[0003] Traditional bearing outer ring stamping equipment typically uses a hydraulic system to push the upper die downwards, which works in conjunction with the lower die to stamp the material. However, when stamping bearing outer rings of different sizes, the upper and lower dies need to be replaced. When replacing the upper die, due to its heavy weight, multiple people are required to lift it for installation or disassembly. This is not only difficult to operate and inefficient, but also can easily lead to arm pain from prolonged lifting, causing the upper die to fall and pose a safety hazard. Furthermore, if it falls and is bumped, it can damage the die, resulting in economic losses. Utility Model Content

[0004] The purpose of this invention is to provide a stamping forming device for producing high-precision roller bearing outer rings. By setting a support mechanism, specifically by positioning the upper die on the stamping base, the rotating support block and the square insert block are simultaneously inserted into the slot. Then, the rotating support block is rotated to misalign with the slot. At this time, the rotating support block restricts and supports the upper die, allowing the upper die to be released without continuous support, facilitating subsequent locking operations. Even during disassembly, prolonged support is not required, improving safety. This solves the problem that traditional stamping equipment requires multiple people to lift and support the heavy upper die during installation or disassembly, making it difficult to operate.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a stamping forming device for producing high-precision roller bearing outer rings, comprising a worktable, a lower die positioned on the top of the worktable, a hydraulic system mounted on the back of the worktable, a stamping seat mounted on the hydraulic system, an upper die disposed at the bottom of the stamping seat, and further comprising:

[0007] The support mechanism is located at the bottom of the stamping base. The support mechanism includes two square blocks fixedly connected to the bottom of the stamping base. A fixed shaft is fixedly connected to the bottom of the square blocks. A rotating support block is rotatably connected to the fixed shaft. Slots are provided on the left and right sides of the upper mold, and insertion holes are provided at the four corners of the upper mold.

[0008] The square insert block and the rotating support block are connected to the upper mold through a slot, and the rotating support block can be rotated on a fixed shaft to adjust its position.

[0009] Furthermore, mounting plates are fixedly connected to the left and right sides of the lower mold, two positioning grooves are opened at the bottom of the lower mold, and two positioning blocks are fixedly connected to the top of the worktable;

[0010] The positioning block corresponds to the positioning groove, the lower mold is inserted into the positioning block through the positioning groove, and the mounting plate is used to insert bolts.

[0011] Furthermore, a threaded shaft is provided inside the insertion hole, the top of the threaded shaft is fixedly connected to the bottom of the stamping seat, a nut is threadedly connected to the outside of the threaded shaft, positioning rods are fixedly connected to the four corners of the top of the upper mold, and four positioning holes are opened at the bottom of the stamping seat.

[0012] Furthermore, the positioning rod is inserted into the stamping seat through the positioning hole, and the positioning rod and the positioning hole are used to position and install the upper mold, and the nut and the threaded shaft are used to lock and fix the upper mold.

[0013] Furthermore, a circular groove is provided at the center of the lower mold, and a demolding push block is slidably connected in the circular groove of the lower mold. A limit rod is slidably connected to the bottom of the demolding push block, and the bottom of the limit rod is fixedly connected to the bottom of the inner wall of the lower mold. A spring is sleeved on the outside of the limit rod. The demolding push block is I-shaped and is used to push out the waste material.

[0014] Furthermore, the top of the spring is fixedly connected to the bottom of the demolding push block, and the bottom of the spring is fixedly connected to the bottom of the inner wall of the lower mold. The spring is used to apply an upward pushing force to the demolding push block.

[0015] This utility model has the following beneficial effects:

[0016] This utility model, by setting up a support mechanism, specifically by positioning and installing the upper mold on the stamping base, allows the rotating support block and the square insert block to be inserted into the slot simultaneously. Then, the rotating support block is rotated to make it misaligned with the slot. At this time, the rotating support block will restrict and support the upper mold, thus releasing the upper mold without the need for continuous support. This facilitates subsequent locking work and also improves safety by eliminating the need for prolonged support during disassembly.

[0017] This invention features a demolding pusher. Specifically, during the stamping process, the demolding pusher is pushed downwards and simultaneously compresses a spring. After stamping is completed, the demolding pusher springs back upwards under the action of elasticity, thus pushing out the waste material. This makes it easier for workers to remove the waste material and improves the forming efficiency of stamping.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a stamping forming device for producing high-precision roller bearing outer rings, including a worktable 1, a lower die 11 positioned on the top of the worktable 1, a hydraulic system 12 installed on the back of the worktable 1, a stamping seat 13 installed on the hydraulic system 12, an upper die 131 provided at the bottom of the stamping seat 13, and further including:

[0030] Support mechanism 2 is located at the bottom of stamping base 13. Support mechanism 2 includes two square inserts 21 fixedly connected to the bottom of stamping base 13. A fixed shaft 22 is fixedly connected to the bottom of the square inserts 21. A rotating support block 23 is rotatably connected to the fixed shaft 22. Slots 311 are provided on the left and right sides of the upper mold 131, and insertion holes 312 are provided at the four corners of the upper mold 131. When the upper mold 131 is positioned and installed on the stamping base 13, the rotating support block 23 and the square inserts 21 will be inserted into the slots 311 at the same time. Then, the rotating support block 23 is rotated to make it misaligned with the slots 311. At this time, the rotating support block 23 will restrict and support the upper mold 131, so the upper mold 131 can be released without continuous support. This facilitates subsequent locking work and also improves safety by eliminating the need for prolonged support during disassembly.

[0031] The square insert 21 and the rotating support block 23 are connected to the upper mold 131 through the slot 311. The rotating support block 23 can be rotated on the fixed shaft 22 to adjust its position.

[0032] The lower mold 11 has mounting plates 111 fixedly connected to its left and right sides. The bottom of the lower mold 11 has two positioning grooves 112, and the top of the worktable 1 has two positioning blocks 14 fixedly connected to its top.

[0033] The positioning block 14 corresponds to the positioning groove 112. The lower mold 11 is inserted into the positioning block 14 through the positioning groove 112. The mounting plate 111 is used to insert bolts.

[0034] The insertion hole 312 is provided with a threaded shaft 132. The top of the threaded shaft 132 is fixedly connected to the bottom of the stamping seat 13. The threaded shaft 132 is threadedly connected to a nut 321. The four corners of the top of the upper mold 131 are fixedly connected with positioning rods 313. The bottom of the stamping seat 13 is provided with four positioning holes 133.

[0035] The positioning rod 313 is inserted into the stamping seat 13 through the positioning hole 133. The positioning rod 313 and the positioning hole 133 cooperate to position and install the upper mold 131. The nut 321 cooperates with the threaded shaft 132 to lock and fix the upper mold 131.

[0036] A circular groove is provided at the center of the lower mold 11. A demolding push block 3 is slidably connected in the circular groove of the lower mold 11. A limit rod 31 is slidably connected to the bottom of the demolding push block 3. The bottom of the limit rod 31 is fixedly connected to the bottom of the inner wall of the lower mold 11. A spring 32 is sleeved on the outside of the limit rod 31. The demolding push block 3 is I-shaped and is used to push out the waste material. During the stamping process, the demolding push block 3 is pushed downward and squeezes the spring 32. After the stamping is completed, the demolding push block 3 is springed back to its original position by the action of the elastic force, and the demolding push block 3 pushes out the waste material, which makes it convenient for the workers to remove the waste material and improves the forming efficiency of the stamping.

[0037] The top of the spring 32 is fixedly connected to the bottom of the demolding push block 3, and the bottom of the spring 32 is fixedly connected to the bottom of the inner wall of the lower mold 11. The spring 32 is used to apply an upward pushing force to the demolding push block 3.

[0038] One specific application of this embodiment is:

[0039] In use, the lower mold 11 is positioned and inserted into the positioning block 14 through the positioning groove 112 at the bottom, thereby positioning the lower mold 11 on the worktable 1. Then, bolts are inserted into the mounting plate 111 and threaded into the worktable 1 to install and fix the lower mold 11. When installing the upper mold 131, the upper mold 131 is inserted into the positioning hole 133 on the stamping seat 13 through the positioning rod 313 at the top, positioning and installing the upper mold 131. At the same time, the threaded shaft 132 is inserted into the insertion hole 312, and the rotating support block 23 and the square insertion block 21 are simultaneously inserted into the slot 311. When the upper mold... When the top of the upper die 131 contacts the bottom of the stamping base 13, the rotating support block 23 moves to the bottom of the upper die 131. Then the rotating support block 23 is rotated to make the rotating support block 23 misaligned with the slot 311. The rotating support block 23 then rotates on the fixed shaft 22. At this time, the rotating support block 23 will restrict the upper die 131, and the upper die 131 can be released without supporting it. This method can support the upper die 131 during installation, which is convenient for subsequent locking work. Finally, the nut 321 is threaded onto the threaded shaft 132 to lock and fix the upper die 131.

[0040] When stamping is required, the metal material is placed on the lower die 11. Then, the hydraulic cylinder in the hydraulic system 12 drives the stamping seat 13 to move downward. The hydraulic system 12 includes a power source (gear pump), an actuator (hydraulic cylinder), a control and adjustment device (directional control valve, pressure control valve, flow control valve), and auxiliary components (oil tank, filter, pipeline, seal, accumulator, cooler / heater). The upper die 131 will cooperate with the lower die 11 to stamp the metal material. The protrusion at the bottom of the upper die 131 will enter the interior of the lower die 11, and at the same time, push the stamped scrap into the lower die 11. At this time, the demolding push block 3 will be pushed downward and slide on the limit rod 31. At the same time, the demolding push block 3 will squeeze the spring 32. After the stamping is completed, the demolding push block 3 will spring back to its original position under the action of the elastic force, and the demolding push block 3 will push out the scrap, making it convenient for the workers to remove the scrap and improving the forming efficiency of stamping.
