Description

Technical Field

[0001] This application relates to the field of punch presses, and more particularly to a punch press for oil pipe flanges. Background Technology

[0002] A punch press is a mechanical device that applies pressure to materials through a stamping die to achieve processing such as cutting, forming, and stretching. Its core function is to quickly process raw materials into parts of a specific shape.

[0003] Although refueling hoses are mostly bent pipes, the connecting flanges at the pipe ends need to be processed by a punch press. These components need to be punched by a punch press to ensure that they can be securely assembled with the vehicle body or fuel tank.

[0004] When performing punching operations, operators need to put their hands or arms into the dangerous working area of ​​the punch press. If the equipment malfunctions, the foot switch fails to control, or the operator is not focused, is fatigued, or makes a mistake, it can easily lead to serious work-related accidents. Utility Model Content

[0005] To ensure the personal safety of workers, this application provides a punch press for oil pipe flanges.

[0006] This application provides a punch press for oil pipe flanges, which adopts the following technical solution: A punch press for oil pipe flanges includes a punch press body, a moving die, a fixed die, and a guide. The fixed die is disposed on the worktable of the punch press body, and the moving die is located directly above the fixed die and disposed at the drive end of the punch press body. The fixed die includes a fixed die base and a sliding base. The fixed die base is disposed on the punch press body, and the sliding base is slidably connected to the fixed die base in a horizontal direction. The sliding base has a placement groove for placing flanges. The guide includes a guide frame and a guide post. The guide frame has a first sliding groove, which is inclined. The guide post is disposed on the sliding base and located within the first sliding groove. When the guide post is located at the lower end of the first sliding groove, the sliding base is located directly below the moving die. When the guide post is located at the upper end of the first sliding groove, the sliding base and the moving die are misaligned.

[0007] By adopting the above technical solution, the guide column cooperates with the inclined first sliding groove to drive the sliding seat to slide horizontally along the fixed mold seat, so as to achieve precise alignment or misalignment between the sliding seat and the moving mold. When the sliding seat and the moving mold are misaligned, the operator can place and remove the flange outside the dangerous working area of ​​the punch press, avoiding the need to put hands into the dangerous area to reduce the risk of work injury. At the same time, there is no need to manually adjust the position of the sliding seat, which effectively improves the processing efficiency of the oil pipe flange.

[0008] Optionally, the guide frame is provided with a second sliding groove, which is vertically arranged. The lower end of the second sliding groove is connected to the upper end of the first sliding groove. The second sliding groove is for the guide column to enter. When the guide column is located at the top of the second sliding groove, the moving mold and the fixed mold are in the mold closing state.

[0009] By adopting the above technical solution, the vertically set second sliding groove on the guide frame is connected to the upper end of the first sliding groove. After the guide column enters the second sliding groove, it can limit the horizontal displacement of the sliding seat, ensuring accurate positioning when the moving mold and the fixed mold are closed, and improving the punching accuracy of the flange. At the same time, the vertical second sliding groove can provide stable guidance for the moving mold closing process, reduce equipment shaking during mold closing, ensure the stability of the entire processing process, and further optimize the punching quality.

[0010] Optionally, the bottom of the placement groove is provided with a release hole to facilitate the removal of punching waste.

[0011] By adopting the above technical solution, the release hole opened at the bottom of the fixed mold sliding seat placement groove can serve as a discharge channel for punching waste, avoiding the accumulation of waste in the placement groove and affecting subsequent flange processing. It eliminates the need for frequent manual cleaning of waste, improving processing continuity. At the same time, the waste can be quickly released through the release hole, reducing friction or squeezing between the waste and the flange processing surface, avoiding damage to the flange surface, and ensuring the product quality of the oil pipe flange.

[0012] Optionally, a receiving groove is provided on the side wall of the sliding seat. The receiving groove is located below the placement groove and extends horizontally. The receiving groove communicates with the release hole, and a receiving frame for receiving waste is placed inside the receiving groove.

[0013] By adopting the above technical solution, the receiving groove on the side wall of the sliding seat is connected to the release hole, and the receiving frame placed in the receiving groove can collect the punching waste falling from the release hole, preventing the waste from scattering and polluting the equipment or working environment, and facilitating the unified treatment of waste in the future; at the same time, the receiving groove extends in the horizontal direction, so that the receiving frame can be quickly pulled out and unloaded, reducing the difficulty of waste treatment and further improving the overall processing efficiency.

[0014] Optionally, the placement groove extends through one side wall of the sliding seat.

[0015] By adopting the above technical solution, the slot is placed through one side wall of the sliding seat to form a channel for side loading and unloading of flanges. Operators can quickly place and remove flanges from the side, simplifying the operation process. At the same time, combined with the function of misalignment between the sliding seat and the moving mold, the side opening can further expand the operating space, avoid interference with other parts of the punch press when loading and unloading flanges, and improve the convenience of operation.

[0016] Optionally, the sidewall of the placement groove is provided with a plurality of mounting grooves, which are distributed along the axial direction of the flange, and the mounting grooves are used to place magnets.

[0017] By adopting the above technical solution, the magnet placed in the mounting groove can magnetically attract the oil pipe flange, preventing the flange from shifting due to vibration during the stamping process and ensuring the accuracy of the punching position; moreover, magnetic attraction eliminates the need for additional clamping structures, simplifying the fixing and disassembly steps of the flange, while avoiding clamping force from damaging the flange and effectively protecting the surface quality of the flange.

[0018] Optionally, a limiting block is provided on the moving mold base. When the fixed mold and the sliding seat are closed, the limiting block is located in the placement groove, and the limiting block is used to abut against the side wall of the flange that is not in contact with the placement groove.

[0019] By adopting the above technical solution, the limiting block on the moving mold base extends into the placement groove when the fixed mold and the sliding seat are closed, and abuts against the side wall of the flange that is not in contact with the placement groove. It cooperates with the placement groove to form a two-way positioning of the flange, further restricting the displacement of the flange and improving the punching accuracy. At the same time, the all-round positioning can reduce the deformation of the flange during the stamping process, ensure the dimensional consistency of the flanges processed in batches, and meet the accuracy requirements for subsequent assembly with the body or fuel tank.

[0020] Optionally, the limiting block is provided with a guide slope to facilitate the guide flange to abut against the side wall of the placement groove.

[0021] By adopting the above technical solution, the guide ramp on the limiting block can provide guidance when placing the flange, helping operators to quickly and accurately fit the flange into the side wall of the placement slot, reducing the difficulty of flange positioning and improving operating efficiency; at the same time, the guide ramp can reduce bumps or jamming during flange placement, avoid processing errors caused by improper positioning, and further ensure the processing quality of the flange.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the sliding structure and the misalignment design of the moving die, combined with the optimization of the lateral pick-up and drop-off channel, operators can pick up and drop off the flange outside the dangerous working area of ​​the punch press, without having to put their hands or arms into the high-risk area between the moving die and the fixed die, which greatly reduces the safety hazards in the stamping process and provides operators with a safer working environment; 2. A collaborative guarantee is formed from three dimensions: mold closing and positioning, workpiece fixing, and multi-directional limiting: The horizontal displacement of sliding parts is limited by a specific structure to ensure accurate alignment during mold closing; the workpiece is fixed by magnetic adsorption to avoid displacement caused by stamping vibration; and the cooperation between the limiting parts and the placement groove achieves bidirectional positioning, which not only effectively avoids punching deviation, but also reduces problems such as clamping force damage and scrap friction damage, ensuring the consistency of flange dimensions and surface quality, and meeting the precision requirements for subsequent stable assembly with the vehicle body or fuel tank; 3. The automatic waste discharge channel design eliminates the need for manual cleaning of accumulated waste; the pull-out waste collection structure simplifies waste handling steps; the guide ramp assists in quick workpiece positioning, reducing operational difficulty; and the sliding component position can be automatically adjusted without manual adjustment, achieving automated alignment.

The guide post 42 is fixedly installed on the corresponding two side walls of the sliding seat 32. It is slidably connected to the first sliding groove 43 and the second sliding groove 44 of the corresponding guide frame 41. When the guide post 42 is located at the lower end of the first sliding groove 43, the orthographic projection of the sliding seat 32 and the moving mold 2 is misaligned. When the guide post 42 is located at the upper end of the first sliding groove 43, the sliding seat 32 is located directly below the moving mold 2. When the guide post 42 is located at the upper end of the second sliding groove 44, the sliding seat 32 and the moving mold 2 are in the mold closing state.

[0031] Reference Figure 2 and Figure 3 The sliding seat 32 has a placement groove 321 extending vertically and penetrating one side wall of the sliding seat 32. The placement groove 321 is used to place a flange. Six release holes 322 are provided at the bottom of the groove 321, evenly distributed circumferentially along the axis of the side wall of the groove used for attaching the flange.
