Description

Technical Field

[0001] The invention relates to the technical field of switch socket processing, in particular to a switch socket accessory forming processing device. Background Art

[0002] Switches and sockets are devices in electrical equipment used to control the on and off of circuits and provide power interfaces for electrical appliances. Switches and sockets include accessories such as middle plates, panels, junction boxes, terminal blocks and grounding wires. Among them, the middle plate plays an important role in switches and sockets. It is usually located between the junction box in the wall and the panel visible to the outside. It is part of the electrical device and is used to ensure that the wires are correctly connected to the switch or socket and provide a stable installation platform.

[0003] Usually, the middle plate is formed on the metal plate by a stamping process. The metal plate is fed intermittently and equidistantly from left to right, and three stamping steps are performed simultaneously in sequence to finally form the required middle plate. The stamping operation mainly includes three stamping steps. The first stamping operation forms the mounting holes around the top of the metal plate and the square groove in the middle area. The second stamping operation forms the front and rear sides and the designated areas on the left and right sides of the metal plate into the required shape. The third stamping operation punches out waist-shaped grooves in the designated shape areas on the front and rear sides of the metal plate. Finally, the formed middle plates are cut from the metal plate one by one.

[0004] However, the following problems exist during the above-mentioned stamping operation: although the unstamped part of the metal plate is pressed up and down before stamping, the metal plate is only limited and fixed in the up and down directions. The limiting effect of the metal plate is not sufficient, and the metal plate is prone to position deviation during the stamping process. At the same time, the metal plate is also prone to deviation in the process of moving to the next stamping point after completing a single stamping operation, resulting in the loss of the stamping reference and the stamping position deviating from the designated stamping area on the metal plate.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 and Figure 2 As shown, a switch socket accessory forming and processing device comprises: a base 1, wherein four support columns 2 arranged in a rectangular shape and with vertical axes are fixedly arranged on the upper end surface of the base 1, a stamping seat 3 is provided on all the support columns 2 for sliding up and down together, the stamping seat 3 is driven by an external hydraulic cylinder (not shown in the figure) to move up and down, and three stamping dies 30 arranged equidistantly from left to right are fixedly provided on the lower end surface of the stamping seat 3, the three stamping dies 30 correspond to three stamping steps respectively, and the adjacent spacings between the three stamping dies 30 are equal to the length of the middle plate.

[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the base 1 is provided with a guiding mechanism 4 for guiding the limiting and stamping process of the metal plate, and the guiding mechanism 4 includes a fixed column 40. Four groups of column groups equidistantly arranged from left to right are fixedly provided on the upper end surface of the base 1, and the column group includes two fixed columns 40 distributed front and back and with vertical axes. A moving bar 400 sliding up and down is provided on the fixed column 40, and a pressure plate 401 is commonly provided between the two moving bars 400 on the leftmost side, and L-shaped guide plates 402 are fixedly provided on the left and right sides of the remaining moving bars 400. The four guide plates 402 corresponding to the same column group together constitute a limiting station, and the inner corner of the guide plate 402 faces the middle of the limiting station, and the limiting stations and the stamping dies 30 are alternately distributed, and the alternating distribution starts with the stamping dies 30.

[0036] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Fig.10 and Fig.11 As shown, V-shaped plates 403 are provided on both sides of the upper end face of the base 1 for sliding up and down through connecting shafts, and the two V-shaped plates 403 are symmetrical front to back, and the two ends of the V-shaped plates 403 are respectively fixedly connected to the two middle moving bars 400, and the leftmost moving bar 400 and the rightmost moving bar 400 are both fixedly provided with reinforcing plates 404 between their respective adjacent moving bars 400, and the base 1 is provided with a fixing unit 47 for fixing the reinforcing plates 404 and the V-shaped plates 403, and the reinforcing plates 404 and the V-shaped plates 403 are locked by the fixing unit 47 to form a stable guiding reference for multiple triangular frames.

[0037] It should be noted that the metal plate as the raw material is intermittently conveyed from left to right by an existing external conveying equipment, and the intermittent conveying distance is the length of a single middle plate in the left-right direction. Secondly, after completing the above three stamping steps, the formed middle plate is cut and separated from the metal plate by an existing external slitting tool on the right side of the base 1, so as to carry out continuous processing of the middle plate.

[0038] The three stamping dies 30 correspond from left to right to the stamping of the surrounding mounting holes and the middle square groove, the stamping of the specified shape areas on the front and rear sides and the left and right sides, and the stamping of the waist-shaped grooves in the specified shape areas on the front and rear sides. The mounting holes are used for the subsequent installation of the middle plate, and the waist-shaped grooves are used to install other accessories in the switch socket.

[0039] During operation, the metal plate stops moving after being transported from left to right to the designated position. At this time, the external hydraulic cylinder works to move the stamping seat 3 downward. During the downward movement of the stamping seat 3, the V-shaped plate 403, the reinforcing plate 404, the pressure plate 401 and the guide plate 402 are driven to move downward synchronously, so as to limit and guide the metal plate in each limit station, and the metal plates on the left and right sides of the stamping position are pressed tightly on the base 1 to ensure the stability and flatness of the metal plate before the stamping operation. Then, as the stamping seat 3 continues to move downward, the fixed unit 47 locks the V-shaped plate 403 and the reinforcing plate 404, so that the guide plate 402, the pressure plate 401, the V-shaped plate 403 and the reinforcing plate 404 jointly form a limit guide reference of multiple triangular frames to ensure the stability of the limit process. Then, the stamping seat 3 drives the stamping die 30 to move downward to perform the corresponding stamping steps. After the stamping is completed, the external existing conveying equipment works to drive the metal plate to continue to move right intermittently.

[0040] In summary, by providing sufficient limiting guidance for the metal plates on the left and right sides of each stamping position, it is ensured that the stamping area on the metal plate can be accurately moved to directly below the stamping die 30, thereby improving the accuracy of the stamping operation. At the same time, the stability of the stamping process is improved by the above-mentioned process of limiting and pressing the metal plate, thereby improving the forming quality of the middle plate.

[0041] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a transverse frame 41 is fixedly provided on the movable bar 400 on the far left and the far right, and the transverse frame 41 is slidably sleeved on the adjacent support column 2 up and down, a spring 410 sleeved on the support column 2 is fixedly provided between the transverse frame 41 and the stamping seat 3, and a return spring 411 sleeved on the corresponding fixed column 40 is fixedly provided between the movable bar 400 and the base 1.

[0042] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a reference cylinder 42 sleeved on the support column 2 is fixedly provided on the lower end surface of the transverse frame 41. When the reference cylinder 42 moves downward and finally contacts with the upper end surface of the base 1, the guiding process is completed.

[0043] like Figure 4 and Fig. 9 As shown, the lower end surface of the guide plate 402 is chamfered, and the two surfaces of the positive corner area of ​​the guide plate 402 are fixedly provided with a pressing block 43 .

[0044] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Fig. 9 , Fig.10 and Fig.11 As shown, a guide column 44 with a vertical axis is fixedly provided on the lower end surface of the lower pressing block 43. The lower end surface of the guide column 44 is chamfered. When the lower pressing block 43 presses the metal plate, the guide column 44 is inserted into the mounting hole at the corresponding position on the metal plate to guide and limit the metal plate.

[0045] During operation, as the punching seat 3 continues to move downward, the punching seat 3 presses spring 410 downward so that spring 410 is compressed, and the return spring 411 is also compressed. The elastic force generated by the compression deformation of spring 410 causes the transverse frame 41 to drive all the moving bars 400 to move downward synchronously. During this process, the support column 2 not only guides the downward movement of the punching seat 3, but also guides the downward movement of the transverse frame 41, the moving bar 400, the pressure plate 401 and the guide plate 402, to ensure that the guide plate 402 can be accurately moved to the specified guide position.

[0046] As the stamping seat 3 continues to move downward, the four guide plates 402 in the same limiting station move downward to the corresponding guide area, which is a square groove formed after the first stamping die 30 is stamped. The chamfering treatment on the guide plate 402 facilitates the guide plate 402 to move downward into the square groove, and the square groove is limited by the cooperation between the corresponding four guide plates 402. As the guide plate 402 continues to move downward, the lower pressing block 43 on the guide plate 402 presses the metal plate downward onto the base 1, that is, the metal plate is pressed and limited in the up and down directions. At the same time, the guide column 44 on the lower pressing block 43 is inserted into the mounting hole at the corresponding position for limiting, and at the same time, the pressure plate 401 on the left moves down to press the metal plate; when the stamping operation is completed, the elastic force generated by the deformation of the spring 1 410 and the reset spring 411 causes the guide plate 402 and the guide column 44 to move up and reset, and the metal plate resumes feeding.

[0047] like Figure 6 , Figure 7 and Figure 8 As shown, the opposite surfaces of the two leftmost movable bars 400 are fixedly provided with connecting frames 1 45, and the opposite surfaces of the other two front and rear opposite movable bars 400 are fixedly provided with connecting frames 2 450, and the two ends of the connecting frames 2 450 are respectively fixedly connected to the corresponding guide plates 402, and the lower end surfaces of all the connecting frames 2 450 in the two right-side limit stations are fixedly provided with auxiliary pressure blocks 451 through square blocks, and the lower end surfaces of the auxiliary pressure blocks 451 are fixedly provided with two left-and-right distributed plug-in columns 452.

[0048] like Figure 1 , Figure 6 , Figure 7 , Figure 8 , Fig.10 and Fig.11As shown, the length of the plug-in column 452 on the auxiliary pressure block 451 on the left is smaller than the length of the plug-in column 452 on the auxiliary pressure block 451 on the right, and an auxiliary pressure circular plate 453 is provided on the plug-in column 452. The auxiliary pressure circular plate 453 corresponding to the auxiliary pressure block 451 on the left is fixedly sleeved on the lower end of the corresponding plug-in column 452, and the auxiliary pressure circular plate 453 corresponding to the auxiliary pressure block 451 on the right is fixedly sleeved on the upper end of the corresponding plug-in column 452. The lower end surface of the plug-in column 452 on the right auxiliary pressure block 451 is chamfered.

[0049] During operation, as the stamping seat 3 continues to move downward, the connecting frame 2 450 drives the corresponding auxiliary pressure block 451 and the plug-in column 452 to move downward synchronously. After completing the second stamping step, the front and rear sides of the square groove are punched out with installation areas of specified shapes, and in the third stamping step, the installation area is punched to form the required waist-shaped groove. The auxiliary pressure block 451 drives the auxiliary pressure circular plate 453 to move downward and press the installation area on the metal plate on the right side of the workstation corresponding to the second stamping step. The auxiliary pressure circular plate 453 on the right side of the workstation corresponding to the third stamping step also presses the corresponding installation area on the metal plate. At the same time, the corresponding plug-in column 452 on the auxiliary pressure circular plate 453 passes through the corresponding waist-shaped groove, thereby limiting and fixing it again.

[0050] In summary, according to the shape of the corresponding area on the metal plate after each stamping operation, the limit fixation in the left and right areas of the workstation corresponding to each stamping step is achieved to ensure the accuracy and stability of the metal plate stamping process.

[0051] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, a side plate 46 is fixedly provided on the right end face of the connecting frame 45, a pressure plate 401 is fixedly provided on the lower end face of the side plate 46, guide grooves 460 are provided on the end faces of the side plate 46 and all guide plates 402 facing the adjacent stamping dies 30, and guide blocks 461 cooperating with the corresponding guide grooves 460 are fixedly provided on the stamping dies 30.

[0052] When the limiting guidance of the corresponding metal plate is completed and the fixing unit 47 is locked, the designated stamping area on the metal plate is located directly below the stamping die 30. As the stamping seat 3 continues to move downward, the stamping die 30 is driven to move downward synchronously. During the downward movement of the stamping die 30, the guide block 461 on the stamping die 30 is inserted into the corresponding guide groove 460, thereby guiding and limiting the downward stamping process of the stamping die 30 in the above manner, ensuring the accuracy of the stamping process and improving the stamping processing quality.

[0053] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the fixing unit 47 includes a fixing rod 470, and two fixing rods 470 distributed left and right and with axes extending from front to back are fixedly provided on the front and rear end surfaces of the base 1, and sliding blocks 471 are provided on the fixing rod 470 for sliding forward and backward. A fixing strip 472 is commonly provided on the two sliding blocks 471 on the same side, and four clamping blocks 473 arranged from left to right are fixedly provided on the opposite surfaces of the two fixing strips 472, and the clamping blocks 473 are chamfered toward the lower end of the stamping die 30, and the upper end surfaces of the V-shaped plate 403 and the reinforcing plate 404 are provided with clamping grooves 474.

[0054] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Fig.10 and Fig.11 As shown, the fixing unit 47 also includes a lower pressure strip 475, and the front and rear end surfaces of the stamping seat 3 are fixedly provided with the lower pressure strip 475 through an L-shaped frame, and a wedge block 476 is fixedly provided between the sliding block 471 and the corresponding fixing strip 472, and the inclined surface of the wedge block 476 is inclined from top to bottom in the direction away from the base 1, and the lower end surface of the lower pressure strip 475 cooperates with the inclined surface of the corresponding wedge block 476, and a spring 477 mounted on the fixing rod 470 is fixedly provided between the sliding block 471 and the base 1.

[0055] After the metal plate is limited and guided, the slots 474 on the V-shaped plate 403 and the reinforcing plate 404 and the corresponding blocks 473 are located in the same horizontal plane. As the stamping seat 3 continues to move downward, the stamping seat 3 drives the lower pressing strip 475 thereon to move downward synchronously. The lower pressing strip 475 cooperates with the inclined surface on the corresponding wedge block 476, so that the wedge block 476 drives the corresponding sliding block 471 to move synchronously close to the base 1, the spring 477 is compressed, and the fixing strip 472 drives the corresponding The block 473 should be inserted into the corresponding slot 474 to lock all the V-shaped plates 403, the reinforcing plates 404, the guide plates 402 and the pressure plates 401. Then the stamping seat 3 is continuously moved downward for stamping processing, and during this process, the lower pressure strip 475 is continuously moved downward to cooperate with the vertical surface of the wedge block 476, so that the block 473 remains stuck in the corresponding slot 474; the chamfered part on the block 473 facilitates the cooperation between the block 473 and the corresponding slot 474.

[0056] After the stamping operation is completed, the stamping seat 3 is reset, and the elastic force generated by the deformation of the spring 2 477 resets the sliding block 471, while unlocking all the V-shaped plates 403 and reinforcing plates 404, so that the subsequent reset process of the V-shaped plates 403 and reinforcing plates 404 can proceed smoothly.
