Detailed Embodiment

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] In an embodiment of the present application, by providing a precision cutting and positioning stamping die for the chassis of an air conditioner outdoor unit, the problems that the existing positioning stamping die cannot detect the inclination state of the upper die table 2 and does not have the function of trimming the edge of the die are solved. When in use, by utilizing the principle that the second resistance block 55 and the first resistance block 54 move away from each other, a resistance value change is generated between the two. Thus, according to the magnitude of the resistance value, the inclination angle of the upper die table 2 can be judged, and the detection accuracy is higher.

[0028] The technical solution in the embodiment of the present application for solving the above technical problems has the following general idea:

[0029] Refer to Figures 1-6 , an embodiment provided by the present utility model: a precision cutting and positioning stamping die for the chassis of an air conditioner outdoor unit, including a die frame 1, an upper die table 2 and a lower die table 3, further including a positioning component 4 and a measuring and moving component 5; a fitting plate 6 is installed at the top of the upper die table 2, plate grooves 7 are respectively opened on both sides of the top of the fitting plate 6, transverse grooves 8 are respectively opened at the front and rear parts of the top of the plate grooves 7, threaded rods 9 are slidably arranged in the transverse grooves 8, carbide tips 10 are welded to the bottom ends of the threaded rods 9, and the threaded rods 9 are fixed to the fitting plate 6 through nuts, and the carbide tips 10 are used for trimming the facing of the pressing materials remaining on both sides of the edge of the chassis of the air conditioner outdoor unit during stamping; the positioning component 4 is used for aligning the upper die table 2 and the lower die table 3 during the stamping stage; the measuring and moving component 5 is used for detecting the inclination state of the upper die table 2; the upper die table 2, the lower die table 3, the positioning component 4 and the measuring and moving component 5 are all connected to the die frame 1.

[0030] By providing the fitting plate 6, the plate grooves 7, the transverse grooves 8, the threaded rods 9 and the carbide tips 10, first, by using the plate grooves 7 opened on the fitting plate 6 and the transverse grooves 8 opened at the front and rear parts of the plate grooves 7 as moving points, the position of the threaded rods 9 in the transverse grooves 8 is adjusted, so that the carbide tips 10 welded to the bottom ends of the threaded rods 9 are close to the left and right sides of the upper die table 2. Moreover, through the plate grooves 7 and the transverse grooves 8, the two sides of the upper die table 2 with a certain width can be closely attached, and then the carbide tips 10 are used for trimming the facing of the pressing materials remaining on both sides of the edge of the chassis of the air conditioner outdoor unit during stamping.

[0031] Refer to Figure 2 , the positioning component 4 includes positioning sleeves 41 fixed at the four corners of the bottom end of the fitting plate 6, positioning posts 42 are arranged at the bottoms of the positioning sleeves 41, the positioning posts 42 are all slidably connected to fixed posts 43, and one ends of springs 44 are fixedly connected to the bottom ends of the positioning posts 42.

[0032] Further, the fixed posts 43 are installed at the four corners of the top end of the support table 11, springs 44 are sleeved outside the positioning posts 42, and the other ends of the springs 44 are all connected to the top of the support table 11.

[0033] By utilizing the relationship between the positioning sleeve 41 and the positioning post 42 in the positioning component 4, during the stamping process of the upper die table 2 and the lower die table 3, the position accuracy of the two can be ensured, and the problem of stamping deviation can be avoided.

[0034] Referring to Figures 1-2 , a support table 11 is fixedly installed on the bottom wall of the mold rack 1. A lower die table 3 is arranged on the top of the support table 11, and air cylinders 12 are fixedly installed at the four corners of the bottom wall of the support table 11. The telescopic ends of the air cylinders 12 penetrate through the top wall of the support table 11 and are fixedly connected to the bottom of the lower die table 3. Air cylinders 13 are installed at the four corners of the top wall of the mold rack 1, and the telescopic ends of the air cylinders 13 are all connected to the top end of the fitting plate 6. By utilizing the downward movement of the air cylinder 13, the fitting plate 6 and the upper die table 2 installed thereon are driven to perform stamping operations with the lower die table 3 below.

[0035] Referring to Figures 5-6 , the measuring and moving component 5 includes a detection box 51 fixedly connected to the middle of the top end of the fitting plate 6. An inner cavity box 52 is installed on the top wall of the detection box 51. A long strip rheostat 53 is installed in the middle of the rear wall of the inner cavity box 52. A first resistor block 54 and a second resistor block 55 are slidably installed on the upper and lower parts of the long strip rheostat 53 respectively. Wings 56 are installed on the left and right sides of the second resistor block 55. The top ends of the wings 56 are connected to one end of an insulating rope 57. The other end of the insulating rope 57 passes through a fixed pulley 58 fixed to the upper part of the inner cavity box 52 and is connected to the left and right sides of the top end of the first resistor block 54. By utilizing the change in the resistance value between the second resistor block 55 and the first resistor block 54, according to the resistance value, the inclination angle of the upper die table 2 is judged, and the detection accuracy is higher.

[0036] Furthermore, the wings 56 are all slid on the slide rails 59. The two slide rails 59 are respectively installed on the left and right sides of the middle of the rear wall of the detection box 51. The bottom of the wing 56 is connected to one end of a return spring 510, and the other end of the return spring 510 is connected to the raised part at the bottom of the slide rail 59. By utilizing the slide rail 59, the sliding of the wing 56 and the movement of the second resistor block 55 connected to the wing 56 are made more stable, and by utilizing the return spring 510, it can return to a stable state after the gravity ball 513 does not tilt in the subsequent state.

[0037] Furthermore, one end of a suspension rope 511 is fixedly connected to the bottom end of the second resistor block 55. The other end of the suspension rope 511 passes through the middle of a clamping wheel 512 fixed to the bottom wall of the inner cavity box 52 and penetrates through the bottom wall of the detection box 51 and is connected to the top of a gravity ball 513. The gravity ball 513 is arranged at the lower side inside the detection box 51. By utilizing the functions of the suspension rope 511, the clamping wheel 512 and the gravity ball 513, the tilting state of the upper die table 2 can be dynamically sensed in real time. Among them, the function of the clamping wheel 512 is to make the movement of the suspension rope 511 more stable.

[0038] Furthermore, an electrical contact 514 is installed at the top of the detection box 51. Both the first resistance block 54 and the second resistance block 55 are electrically connected to the electrical contact 514. By using the electrical contact 514, the change in the resistance value between the second resistance block 55 and the first resistance block 54 can be better transmitted to the detection device, so as to quickly identify the inclination state of the upper die table 2.

[0039] Working principle: First, by using the plate groove 7 opened on the assembly plate 6 and the transverse grooves 8 opened at the front and rear parts of the plate groove 7 as moving points, the position of the threaded rod 9 in the transverse groove 8 is adjusted, so that the cemented carbide sheet 10 welded to the bottom of the threaded rod 9 closely adheres to the left and right sides of the upper die table 2. And through the plate groove 7 and the transverse groove 8, it can adapt to the two sides of the upper die table 2 with a certain width to be closely attached. Furthermore, the cemented carbide sheet 10 is used to cut the pressed materials remaining on the two side edges of the air conditioner outdoor unit chassis during stamping. Secondly, the inclination condition of the upper die table 2 can be monitored by using the detection assembly 5. When the upper die table 2 has an inclination problem, the gravity ball 513 suspended by the suspension rope 511 in the detection box 51 will shift with the inclination of the upper die table 2, and then pull the suspension rope 511. After the suspension rope 511 is pulled, it will drive the connected second resistance block 55 to slide downward on the long strip variable resistor 53. And the second resistance block 55 will also drive the connected two wing blocks 56 to move downward synchronously. The wing blocks 56 can slide stably on the slide rail 59. And the downward movement of the wing blocks 56 will also affect the insulating rope 57 connected to the top, and through the insulating rope 57 and the action of the passing fixed pulley 58, the first resistance block 54 connected to the other end of the insulating rope 57 is pulled upward, so that the second resistance block 55 and the first resistance block 54 move away from each other, and then the resistance value between the second resistance block 55 and the first resistance block 54 changes, and is transmitted to the external detection device through the electrical contact 514. Thus, according to the size of the resistance value, the inclination angle of the upper die table 2 can be judged, and the detection accuracy is higher.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
