Description

Technical Field

[0001] This utility model relates to the field of muffler manufacturing technology, and in particular to the field of muffler flange stamping technology. Background Technology

[0002] In the production of mufflers, flanges are typically required for connection and assembly. Existing muffler flanges are mainly manufactured by stamping sheet metal. Most flanges are ring-shaped with multiple evenly distributed fixing holes for easy fixing between flanges. When manufacturing flanges using stamping methods, to avoid deformation of the sheet metal or to process holes of different sizes, punching and shaping are required in stages, necessitating processing on different stamping presses. Traditional flange stamping, involving two stamping processes, primarily relies on manual handling of the flanges, resulting in high labor intensity, low production efficiency, and high labor costs. Summary of the Invention

[0003] The purpose of this utility model is to provide a conveying device for two-stage flange stamping, which replaces manual labor with machinery, effectively solves the above-mentioned technical problems, improves production efficiency, and reduces labor costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The flange double-stamping conveyor includes a first punch and a second punch, which are connected by a conveyor mechanism. The conveyor mechanism has a chute and a conveyor belt connected in sequence. The chute is connected to the first punch, and a follow-up receiving shovel that adaptively adjusts its advance and retreat according to the stamping movement of the first punch is provided at the receiving end of the chute. The follow-up receiving shovel receives the flanges provided by the first punch and conveys them to the conveyor belt through the chute. The discharge end of the conveyor belt is connected to the second punch, and a feeding mechanism is provided at the discharge end of the conveyor belt. The feeding mechanism feeds the flanges conveyed by the conveyor belt to the second punch one by one.

[0005] A further aspect of the above scheme is that the chute is inclined, one end of the follower receiving shovel overlaps the chute and can move relative to it, while the other end of the follower receiving shovel extends upward and is connected to the first punch press through a swing mechanism. The swing mechanism follows the punching motion of the first punch press to drive the follower receiving shovel, enabling the follower receiving shovel to establish a receiving state and a clearance state. In the receiving state, when the upper die of the first punch press moves upward and picks up the flange, the follower receiving shovel extends under the upper die of the first punch press and receives the flange that the upper die automatically retracts. In the clearance state, when the upper die of the first punch press moves downward to punch, the follower receiving shovel retracts from under the upper die to make way.

[0006] The above-mentioned solution is further described as follows: the swing mechanism has a first connecting arm, a second connecting arm, a first auxiliary rod, and a second auxiliary rod. The first connecting arm and the second connecting arm are hinged together in an X-shape. One end of the first connecting arm is hinged to the first punch press and moves up and down with the upper die, while the other end of the first connecting arm is hinged to the first auxiliary rod. One end of the second connecting arm is hinged to the first punch press, while the other end of the second connecting arm is hinged to the second auxiliary rod. The end of the second auxiliary rod is hinged together with the end of the first auxiliary rod on the follower receiving shovel, so that the first connecting arm, the second connecting arm, the first auxiliary rod, and the second auxiliary rod form a movable quadrilateral. A positioning protrusion is provided at the cross-hinged part of the first connecting arm and the second connecting arm. The positioning protrusion is inserted into a pre-set guide groove on the follower receiving shovel, and the movement of the follower receiving shovel is guided by the cooperation of the positioning protrusion and the guide groove.

[0007] The above scheme is further described as follows: the feeding mechanism includes a baffle plate, a feeding cylinder, a push block, and a dividing baffle plate. The baffle plate is set on the discharge end of the conveyor belt and directly stops the flange conveyed on the conveyor belt. The push block is set on one side of the discharge end of the conveyor belt and is driven to reciprocate by the feeding cylinder, so that the push block pushes the flange on the conveyor belt from one side of the conveyor belt's conveying direction and sends the flange to the second punch. The movement direction of the push block is perpendicular to the conveying direction of the conveyor belt. The dividing baffle plate and the push block form a linkage relationship, so that when the push block pushes the flange, the dividing baffle plate follows and inserts into the upper side of the conveyor belt to stop the next flange.

[0008] A further improvement of the above scheme is that upward-protruding guardrails are provided on the left and right sides of the conveyor belt in the direction of conveying.

[0009] A further improvement in the above scheme is that the baffle plate is equipped with a sensor, which is used to sense whether the baffle plate is blocking the flange and output a signal to control the operation of the feeding cylinder.

[0010] This invention enables the flanges processed by the first punch press to be received by a follow-up receiving shovel and conveyed to a conveyor belt via a chute. The discharge end of the conveyor belt is connected to the second punch press, and a feeding mechanism is provided on the discharge end of the conveyor belt. The feeding mechanism delivers the flanges conveyed by the conveyor belt to the second punch press one by one. This realizes the automatic transfer and feeding of flanges between the two punching processes. Mechanized transfer replaces manual handling, meets the needs of automated production, improves production efficiency, and reduces labor costs. Attached Figure Description

Detailed Implementation

[0012] The following will further explain the concept, specific structure and technical effects of the utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the utility model.

[0013] It should be noted that in the description of this utility model, the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These terms are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] See Figure 1 , 2 Figures 3, 4, and 5 are schematic diagrams of a preferred embodiment of this utility model. This utility model relates to a conveying device for double-stamping of flanges, including a first punch press 1 and a second punch press 2 arranged at intervals. The first punch press 1 and the second punch press 2 respectively process different parts or structural features of the flange. For example, the first punch press 1 is used to punch the flange shape from the sheet metal and punch holes in the flange, while the second punch press 2 is used for flange shaping and stamping, etc. This embodiment addresses the double-stamping process of the flange. The first punch press 1 and the second punch press 2 used in this embodiment are existing technologies, and their structural principles will not be described in detail here. The first punch press 1 and the second punch press 2 are connected by a conveying mechanism to achieve automatic flange conveying. To facilitate the installation and positioning of the conveying mechanism, appropriate support structures can be added, and corresponding connection space can be reserved on the first punch press 1 and the second punch press 2. The conveying mechanism has a chute 3 and a conveyor belt 4 connected in sequence. The chute 3 is connected to the first punch press 1, and a follow-up receiving shovel 31 is provided at the receiving end of the chute 3. The follow-up receiving shovel 31 is self-adjusting to advance and retreat in accordance with the punching movement of the first punch press 1. The follow-up receiving shovel 31 receives the flanges provided by the first punch press 1 and conveys them to the conveyor belt 4 through the chute 3. The conveyor belt 4 is driven by a power mechanism such as a motor to realize the conveying work. The discharge end of the conveyor belt 4 is connected to the second punch press 2, and a feeding mechanism 6 is provided at the discharge end of the conveyor belt 4. The feeding mechanism 6 sends the flanges conveyed by the conveyor belt 4 to the second punch press 2 one by one.

[0015] Furthermore, the chute 3 is inclined to allow the flange to slide automatically onto the conveyor belt 4. The conveyor belt 4 is horizontally positioned, and upward-protruding guardrails 7 are provided on the left and right sides of the conveyor belt 4 in the conveying direction. The guardrails 7 serve a protective function to prevent the flange from falling off the side of the conveyor belt 4. One end of the follow-up receiving shovel 31 is attached to the chute 3 and can move relative to it, while the other end of the follow-up receiving shovel 31 extends upward and is connected to the first punch press 1 through a swing mechanism 5. The swing mechanism 5 follows the punching motion of the first punch press 1 to drive the follow-up receiving shovel 31, enabling the follow-up receiving shovel 31 to establish a receiving state and an avoidance state. In the receiving state, when the upper die of the first punch press 1 moves upward and simultaneously removes the stamped flange, the follower receiving shovel 31 extends below the upper die of the first punch press 1 and receives the flange that automatically exits from the upper die. The specific actions of the upper die removing the flange and automatically exiting the flange are existing technologies and will not be described in detail here. In the clearance state, when the upper die of the first punch press 1 moves downward to perform stamping, the follower receiving shovel 31 exits from below the upper die to make way, thereby achieving clearance and ensuring that the upper die can normally descend and stamp.

[0016] Furthermore, the swing mechanism 5 has a first connecting arm 51, a second connecting arm 52, a first auxiliary rod 53, and a second auxiliary rod 54. The first connecting arm 51 and the second connecting arm 52 are hinged together in an X-shape. One end of the first connecting arm 51 is hinged to the first punch press 1 and moves up and down with the upper die. The other end of the first connecting arm 51 is hinged to the first auxiliary rod 53. One end of the second connecting arm 52 is hinged to the first punch press 1 in a relatively positioned state. The other end of the second connecting arm 52 is hinged to the second auxiliary rod 54. The end of the second auxiliary rod 54 is hinged together with the end of the first auxiliary rod 53 on the follower receiving shovel 31, so that the first connecting arm 51, the second connecting arm 52, the first auxiliary rod 53, and the second auxiliary rod 54 form a movable quadrilateral. The extension and retraction dynamics are obtained through the change of this quadrilateral, thereby driving the follower receiving shovel 31 to move. Meanwhile, the cross hinge portion of the first connecting arm 51 and the second connecting arm 52 is provided with a positioning protrusion 55. The positioning protrusion 55 is inserted into the pre-set guide groove 311 on the follower receiving shovel 31. The positioning protrusion 55 and the guide groove 311 cooperate to guide the movement of the follower receiving shovel 31, thereby improving the accuracy and effectiveness of the movement.

[0017] The feeding mechanism 6 includes a baffle plate 61, a feeding cylinder 62, a pusher block 63, and a separating baffle plate 64. The baffle plate 61 is located on the discharge end of the conveyor belt 4 and directly blocks the flanges conveyed on the conveyor belt 4. The pusher block 63 is located on one side of the discharge end of the conveyor belt 4 and is driven to reciprocate by the feeding cylinder 62, so that the pusher block 63 pushes the flange on the conveyor belt from one side of the conveying direction of the conveyor belt 4 and sends the flange to the second punch press 2. The movement direction of the pusher block 63 is perpendicular to the conveying direction of the conveyor belt 4. The separating baffle plate 64 is linked with the pusher block 63, so that when the pusher block 63 pushes the flange, the separating baffle plate 64 follows and inserts into the upper side of the conveyor belt 4 to stop the next flange, so that the flanges are sent to the second punch press 2 one by one. A sensor 65 is added to the baffle plate 61. The sensor 65 senses the contact and outputs a signal. The sensor 65 is used to sense whether the baffle plate stops the flange and outputs a signal to control the operation of the feeding cylinder 62, thereby improving the efficiency of the operation. In this embodiment, a PLC controller can be introduced to receive the signal output by the sensor 65, and then the PLC controller can output instructions to control the feeding cylinder 62 to work.

[0018] This invention enables the flanges processed by the first punch press to be received by a follow-up receiving shovel and conveyed to a conveyor belt via a chute. The discharge end of the conveyor belt is connected to the second punch press, and a feeding mechanism is provided on the discharge end of the conveyor belt. The feeding mechanism delivers the flanges conveyed by the conveyor belt to the second punch press one by one. This realizes the automatic transfer and feeding of flanges between the two punching processes. Mechanized transfer replaces manual handling, meets the needs of automated production, improves production efficiency, and reduces labor costs.

[0019] While the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to the same structure and operation as described above and the accompanying drawings. For those skilled in the art, many equivalent improvements and variations can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and variations should all fall within the scope of protection claimed by the present invention.
