Description

Technical Field

[0001] This utility model relates to the field of cold press technology, and more specifically, to a positioning structure for a cold press. Background Technology

[0002] A sheet metal cold press is a device that applies pressure to a sheet metal at room temperature using a mold, causing it to undergo plastic deformation to obtain parts of the desired shape. It is widely used in industries such as automobiles and home appliances, and features high production efficiency, good product strength, and excellent surface quality.

[0003] A search revealed CN222201955U, which discloses a cold press with sheet metal positioning function. The cold press includes a placement plate with a positioning structure on its top and a cold pressing structure on its top. The positioning structure includes a positioning box on the top of the placement plate, adjusting screws on both sides of the positioning box, and two sliding grooves inside the positioning box. This invention provides a cold press with sheet metal positioning function. By rotating the adjusting screws, a connecting rod moves, which in turn moves a moving block, thus positioning the sheet metal. This device has a simple structure and effectively solves the problem of inconvenient positioning of the sheet metal to be cold-pressed, which can lead to misalignment during the cold pressing process, resulting in the sheet metal's shape and size not meeting requirements. Furthermore, the lack of sheet metal positioning can lead to more time and effort being spent adjusting the sheet metal's position, thus affecting production efficiency.

[0004] However, this type of cold press with sheet positioning function still has some shortcomings. For example, although the sheet material to be processed can be fixed and limited by adjusting the reverse movement of the moving block, the moving block can only fix the sheet material from one or both sides, and cannot restrain the displacement of the sheet material perpendicular to the moving direction. This means that even when processing sheets of the same specification, insufficient positioning accuracy can easily affect the consistency of the pressing effect, ultimately damaging the quality of the finished product. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a positioning structure for a cold press, so as to solve the problem that the positioning structure of the cold press in the prior art is not perfect, cannot fully restrict the displacement of the sheet metal, resulting in poor processing consistency of workpieces of the same specification and affecting the quality of finished products.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a positioning structure for a cold press, comprising...

[0007] A base plate, a processing table is fixedly installed on the top left side of the base plate, a bracket is fixedly installed on the top of the processing table, a hydraulic cylinder is fixedly installed on the top of the bracket, a cold pressing plate is fixedly installed at the bottom end of the hydraulic cylinder, and a clamping mechanism is provided in the middle of the top of the processing table.

[0008] An auxiliary positioning component is installed on the surface of the bottom of the bracket. The auxiliary positioning component includes a housing, which is fixedly installed on the outer surface of the bottom of the bracket. A motor is fixedly installed on the outer surface of the middle part of the housing. A gear is fixedly installed on the output end of the motor. Two racks mesh with the outer edge of the gear. The outer surfaces of the two racks are slidably installed with the inner surface of the housing and are diagonally symmetrical about the center of the gear. A connecting plate is fixedly installed on the end of the rack away from the motor. A positioning plate is installed on the side of the connecting plate.

[0009] The connecting plate has a connecting rod and a second motor fixedly installed on its side near the rack. The outer surface of the connecting rod is slidably sleeved with the inner surface of the bottom end of the bracket. The output end of the second motor is fixedly installed with the outer surface of the end of the positioning plate. A connecting ring is fixedly installed on the side of the connecting plate away from the rack. The outer surface of the connecting ring is rotatably installed with the inner surface of the end of the positioning plate.

[0010] The top of both sides of the processing table is fixedly equipped with marking lines, and the marking lines are aligned with the side edge of the cold-pressed plate.

[0011] A feeding assembly is installed on the top right side of the base plate.

[0012] The unloading assembly includes side plates, a third motor, and tracks. Two side plates are provided, with their bottoms fixedly installed to the top of the base plate. A support plate is slidably installed in the middle of the two side plates. Threaded rods are rotatably installed on the inner surfaces of the two side plates near the processing table. A transmission wheel is fixedly sleeved at the bottom end of each of the two threaded rods, and the two transmission wheels are connected via the tracks. The third motor is fixedly installed on the top of the side plates, and its output end is fixedly installed to the top of one of the threaded rods. Slider blocks are fixedly installed at the four corners of the support plate. The outer surfaces of the four sliders are slidably installed to the inner surfaces of the two side plates, and the inner surfaces of the two sliders near the processing table are threadedly connected to the outer surfaces of the two threaded rods. A retaining mechanism is provided at the end of the side plate away from the processing table.

[0013] The enclosure mechanism includes a baffle and an adjusting block. The baffle is hinged to the end of the side plate away from the processing table. A spring is fixedly connected to the lower surface of one end of the adjusting block, and a post is fixedly installed on the lower surface of the other end. The bottom end of the spring is fixedly connected to the inner surface of the side plate, and the outer surface of the bottom end of the post is inserted into the inner surface of the top of the baffle.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, auxiliary positioning components and other structures are incorporated. During sheet metal cold pressing, the sheet metal is first placed in the center of the processing table. A motor is started, driving a gear to rotate, causing two meshing racks to slide towards each other along the outer shell. This pulls the connecting plate and positioning plate to clamp the sheet metal from both sides. After initial positioning, the clamping mechanism secures the sheet metal. The positioning plate is then moved out of the marked line area to prevent interference when the cold pressing plate is pressed down. This method, through the combination of auxiliary positioning and clamping, improves positioning accuracy and processing consistency.

[0016] In the above scheme, a feeding assembly and other structures are set up. After cold pressing, the new sheet material is fed from left to right, pushing the formed sheet material to slide down the feeding assembly and onto the support plate. The motor starts to drive the three-drive threaded rod to rotate, which drives another threaded rod to rotate synchronously through the track, causing the slider to move down. The support plate then drops a certain height, facilitating the subsequent layering of sheet material and achieving orderly collection and centralized feeding. Attached Figure Description

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a positioning structure for a cold press, including...

[0025] A base plate 1 is provided. A processing table 2 is fixedly installed on the top left side of the base plate 1. A bracket 3 is fixedly installed on the top of the processing table 2. A hydraulic cylinder 4 is fixedly installed on the top of the bracket 3. A cold pressing plate 5 is fixedly installed at the bottom end of the hydraulic cylinder 4. A clamping mechanism 7 is provided in the middle of the top of the processing table 2.

[0026] An auxiliary positioning component 8 is installed on the bottom surface of the bracket 3. The auxiliary positioning component 8 includes a housing 80, which is fixedly installed on the outer surface of the bottom of the bracket 3. A motor 81 is fixedly installed on the outer surface of the middle part of the housing 80. A gear 82 is fixedly installed at the output end of the motor 81. Two racks 83 mesh with the outer edge of the gear 82. The outer surfaces of the two racks 83 are slidably installed with the inner surface of the housing 80 and are diagonally symmetrical about the center of the gear 82. A connecting plate 84 is fixedly installed at the end of the rack 83 away from the motor 81. A positioning plate 88 is installed on the side of the connecting plate 84.

[0027] Among them, a connecting rod 85 and a second motor 86 are fixedly installed on the side of the connecting plate 84 near the rack 83. The outer surface of the connecting rod 85 is slidably sleeved with the inner surface of the bottom end of the bracket 3. The output end of the second motor 86 is fixedly installed with the outer surface of the end of the positioning plate 88. A connecting ring 87 is fixedly installed on the side of the connecting plate 84 away from the rack 83. The outer surface of the connecting ring 87 is rotatably installed with the inner surface of the end of the positioning plate 88.

[0028] By setting up structures such as motor 86, when the sheet material is loaded and unloaded in the left and right direction, the positioning plate 88 connected to the output end of motor 86 can be rotated by starting motor 86, and rotated along the outer surface of the connecting ring 87 connected to the side of the connecting plate 84. This allows the positioning plate 88 to be adjusted to a vertical position on the side of the bracket 3, thus avoiding lateral interference to the loading and unloading.

[0029] The top of both sides of the processing table 2 is fixedly equipped with marking lines 6, and the marking lines 6 are aligned with the side edges of the cold press plate 5.

[0030] Among them, the material feeding assembly 9 is installed on the top right side of the base plate 1.

[0031] The unloading assembly 9 includes side plates 90, motor 92, and track 95. There are two side plates 90, and their bottoms are fixedly installed to the top of the base plate 1. A support plate 91 is slidably installed in the middle of the two side plates 90. Threaded rods 93 are rotatably installed on the inner surface of the two side plates 90 near the processing table 2. A transmission wheel 94 is fixedly sleeved at the bottom of the two threaded rods 93. The two transmission wheels 94 are connected by the track 95. Motor 92 is fixedly installed on the top of the side plate 90. The output end of motor 92 is fixedly installed to the top of one threaded rod 93. Slider 96 is fixedly installed at the four corners of the support plate 91. The outer surfaces of the four sliders 96 are slidably installed to the inner surfaces of the two side plates 90. The inner surfaces of the two sliders 96 near the processing table 2 are threadedly connected to the outer surfaces of the two threaded rods 93. A barrier mechanism 97 is provided at the end of the side plate 90 away from the processing table 2.

[0032] The enclosure mechanism 97 includes a baffle 970 and an adjusting block 971. The baffle 970 is hinged to the end of the side plate 90 away from the processing table 2. A spring 972 is fixedly connected to the lower surface of one end of the adjusting block 971, and a plug 973 is fixedly installed on the lower surface of the other end. The bottom end of the spring 972 is fixedly connected to the inner surface of the side plate 90, and the outer surface of the bottom end of the plug 973 is inserted into the inner surface of the top of the baffle 970.

[0033] By setting up the enclosure mechanism 97, when the support plate 91 collects the sheet material, the baffle 970 that is attached to the surface of the support plate 91 can be closed to block the sheet material and prevent it from falling off. Furthermore, by adjusting the adjusting block 971 upwards, the connected spring 972 can be pulled to stretch, and the insert 973 can be moved out from the inner surface of the baffle 970, thereby unlocking the baffle 970 that is hinged to the surface of the side plate 90, making it easier to export the sheet material collected on the support plate 91.

[0034] The working process of this utility model is as follows:

[0035] When cold pressing sheet metal, after placing the sheet metal in the middle area of ​​the top of the processing table 2, first control the motor 81 to drive the gear 82 connected to the output end to rotate, driving the two racks 83 meshing on the upper and lower edges of the gear 82 to move, so that the two racks 83 slide along the inside of the outer shell 80 and move closer to each other, further pulling the connecting plate 84 connected to the end and the positioning plate 88 connected to the side of the connecting plate 84 closer to the left and right sides of the sheet metal. Then, after the sheet metal, which is positioned left and right by the auxiliary positioning component 8, is clamped and fixed by the clamping mechanism 7, the positioning plate 88 is adjusted to be outside the range of the marking line 6 set on the processing table 2 to avoid interference when the cold pressing plate 5 is pressed down. Thus, by pre-positioning the left and right sides of the sheet metal by the auxiliary positioning component 8 and then clamping it by the clamping mechanism 7, the positioning accuracy of the sheet metal can be improved and the processing consistency of sheet metal of the same specification can be maintained.

[0036] After the sheet metal is cold-pressed, new sheet metal can be fed from left to right along the upper surface of the processing table 2. During the feeding process, the formed sheet metal can be pushed down towards the feeding assembly 9, so that the formed sheet metal falls on the surface of the support plate 91. Then, the motor 3 92 can be controlled to drive the threaded rod 93 connected to the output end to rotate, which drives the transmission wheel 94 connected to the bottom end to rotate. Through the track 95, the other transmission wheel 94 and the threaded rod 93 are rotated, which drives the slider 96 connected to the threaded rod 93 to slide down, so that the support plate 91 carries the formed sheet metal to a certain height, so that the sheet metal can be collected and stacked by the feeding assembly 9 for subsequent centralized feeding processing.
