Description

Technical Field

[0001] The utility model relates to the technical field of production and processing equipment, in particular to a continuous stamping precision monitoring device. Background Art

[0002] The parts are produced by continuous stamping dies. The materials are usually steel plates or steel strips. The materials enter from one end of the continuous stamping die through a conveying device. The materials are stamped at different positions in the continuous stamping die, gradually formed and finally blanked. The remaining materials pass through the other end of the stamping die and are cut.

[0003] When the same part of the material is stamped at different positions in the continuous stamping die, the stamping accuracy will decrease. Figure 1 In the actual production process, when the material moves in its length direction, the feed speed often increases, which causes the position of the material to change when it is stamped at different positions of the continuous stamping film. This is the decrease in stamping accuracy. The result of the decrease in stamping accuracy is the appearance of waste parts or defective parts, which are mixed with the qualified parts produced before. How to monitor the decrease in stamping accuracy and distinguish waste or defective parts from qualified parts in time is a problem that needs to be solved. Summary of the invention

[0065] See also Figures 1 to 8 The present embodiment provides a continuous stamping precision monitoring device, including: a mounting column 10, a connecting rod 12, a contact rod 13, a first limit block 14, a stopper 121, a spring 15, a fixing column 16, a pressure sensor sensing sheet and a controller.

[0066] The mounting column 10 is arranged on one side of the continuous stamping die, and a coaxial mounting hole 11 is provided at the upper end of the mounting column 10. Specifically, a mounting groove along the circumferential direction is provided on the inner wall of the mounting hole 11, and a mounting ring is sleeved at the lower end of the connecting rod 12, and the mounting ring is clearance-matched with the mounting groove, so that the connecting rod 12 can rotate in the mounting hole 11 and will not be separated from the mounting hole 11.

[0067] The connecting rod 12 is arranged vertically, and its lower end is rotatably arranged in the mounting hole 11. The contact rod 13 is arranged horizontally, one end of which is connected to the upper end of the connecting rod 12, and the other end of which is used to abut against the material 60 output by the continuous stamping die. The first limit block 14 is connected to the upper end of the mounting column 10. The stopper 121 is connected to the connecting rod 12. The spring 15 is connected to the first limit block 14. One end of the fixed column 16 is connected to the end of the spring 15 away from the first limit block 14. The pressure sensor sensing sheet is installed at the end of the fixed column 16 away from the spring 15, and the pressure sensor sensing sheet is used to collect the pressure between the stopper 121 and the fixed column 16 in real time. The controller is electrically connected to the pressure sensor sensing sheet, and the controller is electrically connected to an alarm. The controller receives the pressure data uploaded by the pressure sensor sensing sheet, and compares the pressure data received by the controller with the built-in pressure threshold. When the pressure data received by the controller is greater than the built-in pressure threshold, the controller sends an alarm signal to the alarm. The pressure sensor sensing sheet and the controller are not shown in the figure. Specifically, a signal amplifier module is also provided. The signal amplifier module is electrically connected to the controller, and the signal amplifier module is electrically connected to the pressure sensor sensing sheet.

[0068] In this embodiment, the contact rod 13 is placed on the material 60 output by the continuous stamping die, and the contact rod 13 and the material 60 are in contact with each other and are not subjected to force. The material 60 is output in a step-by-step manner. In actual production, due to the conveying of the conveying device, when the material 60 is output from the continuous stamping die, the material 60 located outside the continuous stamping die will exceed its normal length. Since the material 60 exceeds its normal length, the contact rod 13 that is in contact with it is triggered, and the controller receives the pressure increase detected at the pressure sensor sensing sheet, and the controller compares the received pressure data with the built-in pressure threshold. When the pressure data received by the controller is greater than the built-in pressure threshold, it means that the conveying speed of the material 60 exceeds the normal range, and the controller sends an alarm signal to the alarm. The stamping accuracy is monitored to decrease in the above manner, and the parts at this time are defective or waste. The worker can stop the stamping machine and take out the parts being stamped at this time to avoid mixing defective parts or waste parts with qualified parts.

[0069] The continuous stamping precision monitoring device also includes a second limit block connected to the upper end of the mounting column 10 and a guide tube.

[0070] The second limit block is connected to the upper end of the mounting column 10, and the guide tube is sleeved outside the spring 15, and one end of the guide tube is connected to the stopper 121. The stopper 121 is located between the first limit block 14 and the second limit block. Under the action of the spring 15, the stopper 121 abuts against the second limit block. The first limit block 14 and the second limit block extend radially along the connecting rod 12 on the end surface of the mounting column 10, and the axis of the spring 15 is an arc. The axis of the guide tube is also an arc, and the pressure sensor sensing sheet and the fixed column 16 are located in the guide tube. The axis of the guide ring and the axis of the spring 15 are both arcs, in order to match the rotation trajectory of the stopper 121.

[0071] In one embodiment, the continuous stamping precision monitoring device further includes: a support tube 17 , a plurality of fixed flaps 18 and a fixed sleeve 19 .

[0072] The support tube 17 is sleeved outside the mounting column 10, and a plurality of circumferentially distributed fixed windows 171 are provided on its outer wall. The outer wall of the mounting column 10 is clearance-matched with the inner wall of the support tube 17, and the mounting column 10 can move up and down and rotate in the support tube 17.

[0073] The fixed flap 18 is located in the corresponding fixed window 171, the upper end of the fixed flap 18 is connected to the inner wall of the upper end of the fixed window 171, and the lower end of the fixed flap 18 protrudes out of the outer wall of the support tube 17. The thickness of the lower end of the fixed flap 18 is greater than the thickness of the upper end.

[0074] The fixing sleeve 19 is sleeved outside the supporting tube 17 , and the inner wall of the upper end thereof can be threadedly connected to the supporting tube 17 , and the lower end thereof can be pressed against the outer sides of the plurality of fixing flaps 18 to drive the inner sides of the plurality of fixing flaps 18 to be pressed against the outer wall of the mounting column 10 .

[0075] In this embodiment, after the fixing sleeve 19 is rotated to disconnect the threaded connection between the fixing sleeve 19 and the support tube 17, the fixing sleeve 19 can move upward outside the support, and the fixing flap 18 is separated from the fixing sleeve 19, and the mounting column 10 in the support tube 17 can move up and down and rotate. Thus, the contact rod 13 can adapt to the situation where the material 60 is at different heights when the continuous stamping die is replaced. The mounting column 10 can rotate to adjust the angle of the contact rod 13 when it contacts the material 60, so as to avoid interference between the contact rod 13 and the structure of the continuous stamping die or the stamping machine.

[0076] In one embodiment, the continuous stamping accuracy monitoring device further includes: a base 20 , a sliding seat 30 and a fixing assembly 40 .

[0077] The base 20 is arranged on one side of the continuous stamping die. The sliding seat 30 is slidably arranged on the base 20, and the sliding seat 30 is used to support the support tube 17. The fixing assembly 40 is used to fix the sliding seat 30 and the base 20. Specifically, the sliding seat 30 can drive the support tube 17 together with the contact rod 13 to approach or move away from the end of the material 60. When different continuous stamping dies are replaced and different parts are stamped, the length of the material 60 extending relative to the continuous stamping die is different, and the sliding seat 30 drives the contact rod 13 to move to adapt to different continuous stamping dies.

[0078] In one embodiment, the base 20 includes two support blocks 21 parallel to each other, and both support blocks 21 are in a bar shape.

[0079] The sliding seat 30 includes a base 31 and two sliding arms 32 .

[0080] The base 31 is located above the support block 21, and a mounting groove 311 with an opening facing downward is provided at the lower end of the base 31. The base 31 is used to support the support tube 17. Two sliding arms 32 are respectively connected to the two ends of the base 31. The two sliding arms 32 are located outside the two support blocks 21 and slide with the corresponding support blocks 21. Specifically, a slide groove is provided outside the two support blocks 21, and a slider is provided on the two sliding arms 32, and the slider slides with the corresponding slide groove.

[0081] The fixing assembly 40 includes: a plurality of mutually parallel first fixing plates 41 , a fixing block 42 , and a plurality of mutually parallel second fixing plates 43 .

[0082] A plurality of mutually parallel first fixing pieces 41 are all located between the two support blocks 21, and both ends of each first fixing piece 41 are respectively connected to the corresponding support block 21. The fixing block 42 is vertically slidably arranged in the mounting groove 311. Specifically, a plurality of vertical slide grooves are provided on the inner peripheral wall of the mounting groove 311, and a plurality of sliders are connected to the outer wall of the fixing block 42. The sliders are slidably matched with the corresponding slide grooves, so that the fixing block 42 can slide up and down in the mounting groove 311 without being separated from the mounting groove 311.

[0083] A plurality of mutually parallel second fixing pieces 43 are connected to the lower end of the fixing block 42, and a fixing groove 44 for accommodating the first fixing piece 41 is formed between two adjacent second fixing pieces 43. The width of the fixing groove 44 is substantially the same as that of the first fixing piece 41, so that the first fixing piece 41 is fixed in the fixing groove 44 after being inserted into the fixing groove 44.

[0084] In this embodiment, the base 31 slides on the two support blocks 21, driving the contact rod 13 to approach or move away from the continuous stamping die. In the above process, when the fixed block 42 rises in the installation groove 311, the second fixed plate 43 is separated from the first fixed plate 41 (the first fixed plate 41 is separated from the fixed groove 44). The base 31 can slide on the support block 21. When the contact rod 13 contacts the material 60, the fixed block 42 moves down and approaches the corresponding first fixed plate 41, and the first fixed plate 41 is inserted into the fixed groove 44 to achieve locking of the fixed block 42 and the base 31.

[0085] In one embodiment, a vertical connection channel 312 is further provided at the upper end of the base 31, and the connection channel 312 is communicated with the mounting groove 311. More than one connection channel 312 is provided.

[0086] The fixing assembly 40 further includes a connecting rod 45 and a connecting ring 46.

[0087] The lower end of the connecting rod 45 passes through the connecting channel 312 and is connected to the fixed block 42. Two connecting rods 45 can be provided, and correspondingly, two connecting channels 312 can also be provided. The connecting ring 46 is coaxially rotatably connected to the fixed sleeve 19, and the lower end of the connecting ring 46 is connected to the upper end of the connecting rod 45. Specifically, there can be many ways to rotatably connect the connecting ring 46 to the fixed sleeve 19, for example, the connecting ring 46 is sleeved with a bearing, and the bearing is sleeved on the outer wall of the lower end of the fixed sleeve 19. It is also possible to connect a rotating ring to the upper end of the connecting ring 46, and to open a circumferential sliding groove on the inner wall of the rotating ring, and to connect a matching ring to the lower end of the fixed sleeve 19, and the outer wall of the matching ring is slidably matched with the sliding groove.

[0088] In this embodiment, the fixing sleeve 19 can fix or release the support tube 17 and the mounting column 10, and can also fix or release the base 31 and the support block 21. When the fixing sleeve 19 is loosened and moved upward, the connecting rod 45 is pulled up, thereby driving the fixing block 42 to move upward, the first fixing sheet 41 is separated from the fixing groove 44, and the base 31 can slide on the support block 21. Conversely, after the fixing sleeve 19 is moved downward, the first fixing sheet 41 is inserted into the corresponding fixing groove 44 to achieve locking.

[0089] In one embodiment, the continuous stamping precision monitoring device further includes a fine-tuning frame 50 , a sliding block 51 and a driving rod 52 .

[0090] The fine-tuning frame 50 is connected to the upper end of the base 31 . Specifically, the fine-tuning frame 50 is a rectangular frame.

[0091] The sliding block 51 is slidably arranged on the fine-tuning frame 50, and the sliding direction of the sliding block 51 is the same as the sliding direction of the base 31. A driving hole along the sliding direction is provided on the sliding block 51, and the upper end of the sliding block 51 is connected to the lower end of the support tube 17. Slide blocks are provided on both sides of the sliding block 51, and a slide groove is provided at the corresponding position of the fine-tuning frame 50. Through the cooperation of the slide groove and the sliding block, the sliding block 51 can slide on the fine-tuning frame 50. The driving rod 52 is rotatably arranged on the fine-tuning frame 50, and the driving rod 52 is threadedly connected to the driving hole. Specifically, two coaxial through holes are provided on the fine-tuning frame 50, and the two ends of the driving rod 52 are rotatably arranged in the corresponding through holes, and the ends of the driving rod 52 are also connected to a handle.

[0092] In this embodiment, after the base 31 is fixed on the support block 21, the handle can be rotated to drive the driving rod 52 to rotate, thereby enabling the sliding block 51 to slide relative to the base 31, thereby fine-tuning the distance between the contact rod 13 and the material 60.

[0093] In one embodiment, the opposite ends of the first fixing sheet 41 and the second fixing sheet 43 are contracted into a cutting edge. The opposite ends of the first fixing sheet 41 and the second fixing sheet 43 are thinned, which facilitates the first fixing sheet 41 to be inserted into the corresponding fixing groove 44.

[0094] In one embodiment, the length of all the second fixing pieces 43 along the sliding direction of the base 31 is greater than the distance between two adjacent first fixing pieces 41. The overall length of the second fixing pieces 43 densely distributed at the lower end of the fixing block 42 is greater than the distance between two adjacent first fixing pieces 41 to ensure that when the fixing block 42 moves downward, there is always a fixing groove 44 that can fit with the first fixing piece 41 for fixing.

However, it is understood that the embodiments of the present utility model can be practiced without these specific details.
