Description

Technical Field

[0001] This application relates to the field of automotive parts processing technology, and in particular to a stamping induction device. Background Technology

[0002] Currently in the automotive manufacturing industry, the shape design of automotive exhaust pipes is quite unique, usually presenting a special structure with one end rectangular and the other end round. This special shape design is to meet the connection requirements of different components in the automotive engine exhaust system and to optimize exhaust performance.

[0003] In current manufacturing processes, the production of automotive exhaust pipes generally involves first creating a cylindrical exhaust pipe using conventional pipe processing methods. This process is relatively mature and stable, ensuring the basic dimensional accuracy and quality of the exhaust pipe. Then, one end of the processed exhaust pipe is fitted onto a pre-made rectangular block. The stamping machine is equipped with guide posts and a stamping head. The guide posts drive the stamping head to make stable up-and-down reciprocating movements, while the stamping head stamps and shapes the exhaust pipe fitted onto the rectangular block.

[0004] In the actual processing, the exhaust pipe is mainly placed on the rectangular block by manual operation. However, manual operation has many uncontrollable factors. Due to the deviation of visual judgment, the difference in hand strength and stability, the depth of the exhaust pipe placed on the rectangular block is inconsistent each time, which affects the position of the exhaust pipe being stamped and thus directly affects the quality of the exhaust pipe after forming. There are areas for improvement. Utility Model Content

[0005] In order to improve the quality of exhaust pipe stamping, this application provides a stamping induction device.

[0006] This application provides a stamping induction device, which adopts the following technical solution:

[0007] A stamping sensing device includes a frame and a fixing block disposed below a stamping machine. The fixing block is disposed on the frame and has a plug for inserting into an exhaust pipe. The plug is connected to an actuating component for controlling the downward pressing of the stamping machine.

[0008] By adopting the above technical solution, the insertion block and the exhaust pipe are connected to form a plug-in fit, which realizes stable support and precise positioning of the exhaust pipe; the fixed block and the insertion block form a detachable connection, which makes it convenient for the staff to maintain the insertion block or replace the insertion block with different specifications, thereby adapting to the insertion of exhaust pipes of different specifications; when the exhaust pipe is inserted into place, the trigger component controls the stamping machine to press down the exhaust pipe, which effectively solves the problem of inconsistent insertion depth of exhaust pipe caused by manual operation, thereby improving the quality and consistency of exhaust pipe stamping.

[0009] Preferably, the trigger assembly includes a trigger spring rod, a trigger switch, and a mounting bracket for fixing the trigger switch. The mounting bracket is connected to the side of the fixing block away from the exhaust pipe. The trigger switch is mounted on the mounting bracket. The trigger spring rod passes through the fixing block and the mounting bracket in sequence. The trigger spring rod and the mounting bracket form an insertion engagement. One end of the trigger spring rod forms an abutment engagement with the trigger switch, and the other end forms an abutment engagement with the exhaust pipe.

[0010] By adopting the above technical solution, when the exhaust pipe is correctly placed and the touch spring rod is pushed to abut against the touch switch, the touch spring rod can trigger the touch switch, thereby controlling the press to press down the exhaust pipe, thus realizing the precise linkage between the exhaust pipe and the press.

[0011] Preferably, the fixing block is provided with an oblong hole, the trigger spring rod is slidably disposed in the oblong hole on the fixing block along its axial direction, and the fixing bracket is slidably disposed on the fixing block along the radial direction of the trigger spring rod.

[0012] By adopting the above technical solution and utilizing the waist-shaped hole, the waist-shaped hole provides sliding space for the trigger spring rod and the fixing bracket, enabling the trigger spring rod to better adapt to the push of exhaust pipes of different specifications, thereby enhancing the versatility and flexibility of the device.

[0013] Preferably, the insert includes a connecting part that snaps onto the fixing block and a supporting part for supporting the exhaust pipe. The connecting part and the supporting part are integrally formed, and the connecting part is provided with a clearance hole for avoiding the sliding of the fixing frame.

[0014] By adopting the above technical solution, the connecting part of the insert block and the fixing block are engaged in a snap-fit, and the connecting part and the supporting part are integrally formed. Thus, the connecting part provides reliable support for the supporting part, improving the overall structural strength and stability of the insert block. At the same time, the setting of the clearance hole allows the sliding of the fixing frame to proceed smoothly.

[0015] Preferably, the frame is symmetrically provided with clamping components for clamping the exhaust pipe.

[0016] By adopting the above technical solution and utilizing the clamping component, the clamping component can firmly clamp the exhaust pipe, effectively preventing deformation or damage to the exhaust pipe due to instability during the stamping process, ensuring the smooth progress of the stamping operation, further improving the quality of stamping, and also improving the safety of the production process.

[0017] Preferably, any of the clamping components includes an electric cylinder and a clamping plate. The electric cylinder is mounted on the frame, and the piston rod of the electric cylinder is connected to the clamping plate. The side of the clamping plate opposite to the electric cylinder forms an abutment fit with the side wall of the exhaust pipe.

[0018] By adopting the above technical solution, and utilizing the electric cylinder and clamping plate, precise clamping and rapid release of the exhaust pipe are achieved. During the stamping process, the electric cylinder can provide a stable clamping force to ensure that the exhaust pipe remains fixed during the stamping process.

[0019] Preferably, guide blocks are symmetrically arranged on the frame, and any one of the guide frames is provided with a guide groove for inserting and engaging with the guide post.

[0020] By adopting the above technical solution, the guide column and guide groove form an interlocking fit, so that the stamping machine maintains a stable and accurate movement trajectory during the pressing process, thereby avoiding the stamping head from deviating or shaking during the pressing process.

[0021] Preferably, the frame is provided with a buffer spring rod for protecting the exhaust pipe during the stamping process.

[0022] By adopting the above technical solution and utilizing the buffer spring rod, the buffer spring rod can play a buffering and protective role for the exhaust pipe during the stamping process, ensuring the quality of the exhaust pipe after stamping and extending the service life of the exhaust pipe.

[0024] 1. By using the insert block to form a plug-in fit with the exhaust pipe, stable support and precise positioning of the exhaust pipe are achieved; by using the fixed block to form a detachable connection with the insert block, it is convenient for workers to maintain the insert block or replace it with insert blocks of different specifications, thereby adapting to the insertion of exhaust pipes of different specifications; when the exhaust pipe is inserted into place, the trigger component controls the stamping machine to press down the exhaust pipe, effectively solving the problem of inconsistent exhaust pipe insertion depth caused by manual operation, thereby improving the quality and consistency of exhaust pipe stamping;

[0025] 2.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0033] This application discloses a stamping induction device.

[0034] Reference Figure 1 and Figure 2 A stamping sensing device includes a frame 1 and a fixing block 2 disposed below a stamping machine. The frame 1 is placed on the ground, and the fixing block 2 is vertically welded to the frame 1. A plug 3 is detachably disposed on the fixing block 2. The plug 3 is disposed perpendicular to the fixing block 2 and forms a plug-in fit with the exhaust pipe, thereby achieving stable support and precise positioning of the exhaust pipe.

[0035] Reference Figure 1 and Figure 3 The insert 3 includes a T-shaped connecting part 31 and a rectangular supporting part 32. The connecting part 31 and the supporting part 32 are integrally formed. The fixing block 2 has a snap-fit ​​groove 21. The connecting part 31 and the snap-fit ​​groove 21 form a snap-fit ​​engagement. The connecting part 31 is fixed to the fixing block 2 by bolts. The supporting part 32 forms an insertion engagement with the inner wall of the exhaust pipe. Thus, the connecting part 31 provides reliable support for the supporting part 32, which improves the overall structural strength and stability of the insert 3. This reduces the possibility of deviation in the stamping position of the exhaust pipe due to the instability of the insert 3 structure during the stamping process.

[0036] Reference Figure 2 and Figure 3The insert block 3 is connected to an actuation component 4 for controlling the downward pressure of the press. The actuation component 4 includes an actuation spring rod 41, an actuation switch 42, and a fixing frame 43. The fixing frame 43 is fixed to the side of the fixing block 2 away from the exhaust pipe by bolts. The actuation spring rod 41 is inserted into the fixing frame 43 along its axial direction. The actuation switch 42 is embedded in the fixing frame 43 and electrically connected to the press control system.

[0037] Reference Figure 3 A waist-shaped hole 22 is provided on the fixing block 2 parallel to the insertion direction of the exhaust pipe. The waist-shaped hole 22 is used to adjust the radial position of the trigger spring rod 41. The waist-shaped hole 22 provides sliding space for the trigger spring rod 41 and the fixing bracket 43, so the fixing bracket 43 can slide on the fixing block 2 along the radial direction of the trigger spring rod 41.

[0038] Reference Figure 3 and Figure 4 The connecting part 31 is provided with a clearance hole 311 for avoiding the sliding of the fixing frame 43 and a stop block 312 for limiting the sliding direction of the fixing frame 43. The stop blocks 312 are symmetrically arranged in the clearance hole 311, and any one of the stop blocks 312 is integrally formed on the connecting part 31. Thus, a limiting space is formed between the stop block 312 and the fixing block 2 to restrict the sliding of the fixing frame 43. The trigger spring rod 41 passes through the waist-shaped hole 22 of the fixing block 2, the fixing frame 43 and the clearance hole 311 of the connecting part 31 in sequence. One end of the trigger spring rod 41 forms an abutting fit with the trigger switch 42, and the other end forms an abutting fit with the end face of the exhaust pipe.

[0039] Reference Figure 3 and Figure 4 When in use, the trigger spring rod 41 drives the fixing bracket 43 to slide to a suitable position radially according to the specifications of the exhaust pipe, so that the trigger spring rod 41 can better adapt to the pushing of exhaust pipes of different specifications. After the position is determined, the fixing bracket 43 is fixed to the fixing block 2 by bolts, which further improves the applicability of the device.

[0040] Reference Figure 3 and Figure 4 During operation, the exhaust pipe pushes the trigger spring rod 41 backward. When the exhaust pipe is fully inserted into the insert block 3, that is, when the trigger spring rod 41 abuts against the trigger switch 42, the trigger switch 42 controls the stamping machine to press down the exhaust pipe, realizing the precise linkage between the exhaust pipe and the stamping machine. This structure ensures that the stamping machine will only start when the exhaust pipe is in the correct position, avoiding stamping failure or damage caused by inaccurate exhaust pipe position, and further improving the reliability of the stamping process and the controllability of product quality.

[0041] Reference Figure 1 and Figure 2The frame 1 is symmetrically provided with clamping components 11 for clamping the outer wall of the exhaust pipe. Since the structure and connection method of the two clamping components 11 are the same, we will now describe one of the clamping components 11 as an example.

[0042] Reference Figure 1 and Figure 2 The clamping assembly 11 includes an electric cylinder 111 and a clamping plate 112. The electric cylinder 111 is horizontally mounted on the frame 1 by bolts and is electrically connected to the touch switch 42. The piston rod of the electric cylinder 111 is connected to the clamping plate 112. The side of the clamping plate 112 away from the electric cylinder 111 forms an abutment fit with the outer wall of the exhaust pipe.

[0043] Reference Figure 1 and Figure 2 Before the stamping machine, the touch switch 42 first controls the electric cylinder 111 to drive the clamping plate 112 to clamp the outer wall of the exhaust pipe, ensuring that the exhaust pipe remains in a stable position during the stamping process. Then, the stamping machine is controlled to press down the exhaust pipe, ensuring the smooth progress of the stamping operation, further improving the quality of the exhaust pipe stamping, and also improving the safety of the production process.

[0044] Reference Figure 1 and Figure 2 A guide block 12 is vertically arranged on the frame 1. Two guide blocks 12 are symmetrically arranged in terms of position and number corresponding to the guide columns. Each guide block 12 has a guide groove 121 opened along its height direction. The guide column and the corresponding guide groove 121 form an interlocking fit to ensure that the stamping head of the stamping machine presses down along the preset trajectory, which effectively improves the stamping accuracy and quality, reduces the deformation or damage of the exhaust pipe caused by the inaccurate position of the stamping head, and further improves the quality of the exhaust pipe and production efficiency.

[0045] Reference Figure 1 and Figure 2 A buffer spring rod 13 is symmetrically arranged on the frame 1. Any buffer spring rod 13 is vertically installed on the frame 1. During stamping, the top of the stamping head and the buffer spring rod 13 form an abutment fit. When the stamping machine presses down, the buffer spring rod 13 can absorb part of the impact force, reduce the instantaneous impact of the stamping head on the exhaust pipe during the stamping process, thereby avoiding quality problems such as cracks and deformation of the exhaust pipe due to excessive force, and extending the service life of the exhaust pipe.

[0046] The implementation principle of this application embodiment is as follows: In actual operation, the operator first selects a suitable insert block 3 according to the specifications of the exhaust pipe, inserts the connecting part 31 of the insert block 3 into the snap-fit ​​groove 21 of the fixing block 2, and then inserts the exhaust pipe onto the support part 32 of the insert block 3. Then, the operator adjusts the position of the fixing frame 43 and the trigger spring rod 41 on the fixing block 2 by turning the bolts to ensure that the fixing frame 43 is installed stably. Then, the operator pushes the exhaust pipe on the support part 32 until the exhaust pipe pushes the trigger spring rod 41 to trigger the trigger switch 42. The trigger switch 42 first automatically controls the electric cylinder 111 to drive the clamping plate 112 to clamp the exhaust pipe, and then automatically controls the stamping machine to press down, thereby completing the stamping and shaping of the exhaust pipe.

[0047] After the stamping is completed, the stamping machine moves up and resets. The electric cylinder 111 drives the clamping plate 112 to retract and release the exhaust pipe. At this time, the spring rod 41 is triggered and bounces away from the trigger switch 42. The worker takes out the formed exhaust pipe and prepares for the next stamping operation.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
