Description

Technical Field

[0001] This utility model belongs to the field of automotive cold stamping die technology. Specifically, this utility model relates to a cylinder mounting block mechanism. Background Technology

[0002] In the side-flipping and side-forming processes of automotive cold stamping dies, the cylinder is a key power component. It needs to be connected to the wedge via a mounting block. The cylinder is fixed on the lower die base. During operation, compressed air pushes the piston rod to extend and retract, thereby driving the wedge to move and converting axial power into lateral stamping power to complete the side bending, shaping, and other forming operations of the parts. Traditional cylinder mounting blocks are mostly one-piece structures, directly and rigidly fixed to the wedge, with the cylinder piston rod locked to the mounting block by bolts or pins. When the cylinder needs to be disassembled for repair or replacement, the entire wedge must first be lifted out of the die using hoisting equipment to release the mounting block's constraint on the piston rod and complete the cylinder separation. After repair, the wedge must be lifted back into the die and its position recalibrated, making cylinder disassembly inconvenient.

[0003] Chinese Patent (Publication No.: 103785750A) discloses an anti-loosening device for connecting a drive cylinder and a side-pull wedge, comprising a side-pull wedge, a retaining plate, a connecting block, a drive cylinder, and a drive piston rod; the side-pull wedge is fixedly connected to the retaining plate; the connecting block and the piston rod of the drive cylinder are threaded together; a T-shaped boss is provided at the connection end between the side-pull wedge and the retaining plate, and a groove is provided inside the retaining plate; the groove contains the transverse side of the T-shaped boss and one end of the connecting block. This structure makes it inconvenient to disassemble the cylinder. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a cylinder mounting block mechanism that facilitates cylinder disassembly. To achieve the above objective, the technical solution adopted by this utility model is as follows: a cylinder mounting block mechanism, including a cylinder and a wedge, wherein the cylinder is connected to the wedge, and includes a mounting seat, wherein the mounting seat is connected to the wedge, and the mounting seat is provided with a disassembly structure, wherein the cylinder piston rod cooperates with the disassembly structure.

[0005] The easy-to-disassemble structure includes a mounting key, and the mounting base has a connecting groove that mates with the mounting key. The mounting key is disposed in the connecting groove, and the mounting base has a locking structure that mates with the mounting key.

[0006] The locking structure includes a screw, which is connected to the mounting base, and the end of the screw abuts against the mounting key.

[0007] The mounting base includes a first mounting block and a second mounting block, which are disposed on the wedge. The two ends of the mounting key are respectively disposed on the first mounting block and the second mounting block, and screws are disposed on both the first mounting block and the second mounting block.

[0008] The mounting key has an arched through hole.

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0015] like Figures 1-2As shown, a cylinder mounting block mechanism includes a cylinder and a wedge, with the cylinder connected to the wedge. The mechanism includes a mounting base 1 connected to the wedge, and a removable structure 2 on the mounting base 1. The cylinder piston rod engages with the removable structure 2. The cylinder is mounted on a lower mold base and fixed thereon. When the cylinder operates, compressed air drives the piston rod, causing the wedge to move. The mounting base 1 is fixed to the wedge, and the removable structure 2 is mounted on the mounting base 1. The mounting base 1 and the removable structure 2 engage with the cylinder piston rod, restricting the piston rod displacement and allowing the piston rod to extend and retract in a specified direction. Simultaneously, when the cylinder needs to be disassembled, the removable structure 2 on the mounting base 1 allows for quick removal, releasing the restriction on the cylinder piston's Z-axis movement. This eliminates the need to lift the wedge out of the mold, allowing the cylinder to be removed easily by the user.

[0016] The easy-to-disassemble structure 2 includes a mounting key 201. A connecting groove 202 is provided on the mounting base 1 to mate with the mounting key 201. The mounting key 201 is disposed within the connecting groove 202. A locking structure 3 is provided on the mounting base 1, which mates with the mounting key 201. The mounting base 1 is fixed to the wedge, and the mounting key 201 is locked to the mounting base 1 by the locking structure 3. The mounting key 201 restricts the Z-axis movement of the cylinder piston, allowing the cylinder piston to move in a specified direction. Simultaneously, by opening the locking structure 3, the mounting key 201 can be removed from the mounting base 1, releasing the Z-axis restriction on the cylinder piston and facilitating subsequent cylinder disassembly. The cylinder can be disassembled without lifting the wedge out of the mold, making it convenient for users. The mounting key 201 is set in the connecting groove 202. When installing the mounting key 201, the mounting key 201 is placed in the connecting groove 202. The connecting groove 202 cooperates with the mounting key 201. After the mounting key 201 is installed in place, it can prevent the mounting key 201 from wobbling left and right. Then, the locking structure 3 can completely fix the mounting key 201.

[0017] The locking structure 3 includes a screw 301, which is connected to the mounting base 1. The end of the screw 301 abuts against the mounting key 201. The mounting key 201 is placed in the connecting groove 202, with one end of the mounting key 201 located at the end of the connecting groove 202 and the other end flush with the mounting base 1. By tightening the screw 301 on the mounting base 1, the end of the screw 301 abuts against the groove, completely fixing the mounting key 201. The mounting key 201 serves as an intermediate structure connecting the cylinder piston rod and the wedge. The mounting key 201 cooperates with the cylinder piston rod, allowing the cylinder piston rod to extend and retract in a specified direction without deviation or wobbling, ensuring that the cylinder maintains accurate positioning and does not loosen during frequent operation.

[0018] Mounting base 1 includes a first mounting block 101 and a second mounting block 102, which are disposed on the wedge. A mounting key 201 is disposed at both ends on the first mounting block 101 and the second mounting block 102, respectively. Screws 301 are provided on both the first mounting block 101 and the second mounting block 102. The original single mounting block is split into the first mounting block 101 and the second mounting block 102. Connecting grooves 202 are provided on the first mounting block 101 and the second mounting block 102. The two ends of the mounting key 201 are embedded into the first mounting block 101 and the second mounting block 102 through the connecting grooves 202, respectively. Screws 301 are connected to both the first mounting block 101 and the second mounting block 102, with the ends of the screws 301 abutting against the mounting key 201, thus connecting the entire structure together. The mounting block mechanism is mounted on the wedge, and the mounting key 201 cooperates with the piston rod of the cylinder.

[0019] The mounting key 201 has an arched through hole 6. The arched through hole 6 inside the mounting key 201 is adapted to the cylindrical outer circumference of the cylinder piston rod, which facilitates the limiting of the cylinder piston rod, ensures the accurate movement trajectory of the cylinder piston rod, and ensures that the cylinder maintains accurate position and does not loosen during frequent operation.

[0020] The mounting base 1 is provided with weight-reducing fixing holes 4. The weight-reducing fixing holes 4 are provided on the mounting base 1 to reduce the overall weight of the mounting base 1 and save materials. By screwing bolts into the weight-reducing fixing holes 4 and fixing them with wedges, and the fact that the weight-reducing fixing holes 4 are arranged in parallel on the mounting base 1, the locking force can be distributed to avoid stress concentration, making the installation more stable and reliable, and better able to cope with the large vibration and impact forces generated during the processing.

[0021] A washer 5 is provided between the screw 301 and the mounting base 1, and the washer 5 abuts against the mounting key 201. The washer 5 is installed between the head of the screw 301 and the contact surface of the mounting base 1, and a portion of the washer 5 abuts against the mounting key 201. This prevents direct wear between the screw 301 and the mounting base 1 and the mounting key 201, protecting the mounting base 1 and the mounting key 201, extending their service life, and preventing the screw 301 from loosening, making the screw 301 more securely fixed to the mounting key 201. At the same time, the vibration of the piston rod during the stamping process is transmitted to the mounting key 201, and the washer 5 can reduce the vibration transmitted to the screw 301 and buffer the impact force of the vibration.

[0022] The mounting key 201 is embedded into the first mounting block 101 and the second mounting block 102 respectively through connecting grooves 202. Screws 301 are connected to both the first and second mounting blocks 101, with the ends of the screws 301 abutting against the mounting key 201, connecting the entire structure together. The cylinder fixed to the lower mold base pushes the piston rod to extend and retract via compressed air. The piston rod engages with the arched through hole 6 of the mounting key 201 via the mounting base 1. The mounting key 201 ensures that the piston rod moves in the specified direction without deviation. For disassembly, the cylinder can be disassembled by unscrewing the screws 301 and removing the washer 5 and the mounting key 201. Removing the mounting key 201 releases the Z-axis restriction on the cylinder piston, facilitating subsequent cylinder disassembly. The cylinder can be disassembled without lifting the wedge out of the mold, making it convenient for users. A single person can complete the cylinder disassembly, reducing equipment downtime. During disassembly, the wedge remains fixed to the mold, eliminating the need for recalibrating its position.
