Description

Technical Field

[0001] The utility model relates to the technical field of safe production, and more specifically, to a variable module forming machine. Background Art

[0002] In the production of safes, the steel coils need to be stretched into steel plates of appropriate thickness, and then go through multiple processes such as cutting and punching. The cold pressing process generally uses a pair of rollers to press the steel plates at low temperatures. After completing all the processes, the steel plates are bent and welded, and the cabinet body is initially formed.

[0003] For example, application number CN201821356712.7 discloses a rib cold bending machine for steel plate processing, including a bottom plate, the top two sides of the bottom plate are welded to the cross frame through symmetrically arranged support plates, a slide groove is opened at the horizontal end of the inner edge of the cross frame, a movable roller is arranged at the horizontal end of the inner edge of the cross frame, and both sides of the movable roller are rotatably connected to the bearing through a rotating shaft, and the bearing is embedded in the slide groove. The connecting roller is driven to rotate by a stepper motor, and rollers of different diameters can be selected to be located directly above the steel plate, and then the second hydraulic cylinder controls the telescopic rod to push the roller downward, and finally contact and press the upper surface of the steel plate to complete the cold bending process. Through this structure, rollers of different diameters can be selected to cold press the steel plate, so that the cold pressing curvature on the upper surface of the steel plate can be accurately controlled, which improves the quality of the cold pressing process and has the characteristics of simple structure and strong practicality.

[0004] However, the existing cold pressing equipment generally disassembles and replaces the corresponding rollers to the specified position in advance according to the planned production size of the steel plate. The process is cumbersome and requires re-calibration, which is time-consuming and labor-intensive, affecting the production progress; the steel plate feeding end is generally a simple receiving platform, which needs to be guided manually or by rollers in the future, and the design is unreasonable; the roller sizes on the existing rollers are generally uniform, and special processes require customized rollers of special sizes. In addition, the rollers at the external transmission force introduction end need to withstand the greatest stress and need special improvements, otherwise it will easily affect the traction efficiency.

[0026] Example:

[0027] The following is combined with Figure 1-2 The utility model is described in further detail.

[0028] Variable modular molding machines, such as Figure 1-2 As shown, the main body is a frame 1, and a position for installing a transmission mechanism is reserved on the left side of the frame 1. The frame 1 is divided into three sections: front, middle and rear. The front end is a driving end, that is, a power end that outputs external force and drives the traction steel plate 6 for transmission; the rear end is a driven end, that is, the steel plate 6 that is already in a transmission state after traction drives the subsequent cold pressing action. Since the driving end continuously outputs power, the steel plate 6 is also in a state of continuous transmission. In theory, the driven end of the cold pressing part will also continue to perform roller cold pressing on the steel plate 6.

[0029] The initial position of the driving end is a positioning rack 2 that does not participate in the transmission. The positioning rack 2 is at the front end of the entire frame 1, and is mainly composed of two slidable limit racks 21. A special screw assembly 22 is provided below. The limit rack 21 is connected to the sliding part of the screw assembly 22. The positions of the two limit racks 21 (corresponding to determining the cold pressing line) and the distance between the two limit racks 21 (corresponding to determining the width of the cold pressed steel plate 6) can be quickly and conveniently adjusted through the screw assembly 22. The limit rack 21 plays a role in guiding and correcting positioning.

[0030] The next part of the driving end is the traction roller group 3 that plays the role of traction drive. The traction roller group 3 is located at the rear end of the positioning material rack 2. Generally, there are six groups. The first two groups have driving motors, and the last four groups are transmission matching groups involved in traction. Each group of traction roller groups 3 is composed of two upper and lower rollers 4 that can be adjusted to move closer or farther away from each other. On the left side of these six groups of traction roller groups 3, that is, the position reserved for the transmission mechanism, the corresponding traction transmission assembly 5 is installed, which includes two drive motors and a belt or chain transmission mechanism. The transmission mechanism is connected to each roller 4 of the traction roller group 3 to form a complete drive and transmission structure.

[0031] Next comes the main part of cold pressing, the cold pressing roller group at the driven end. There are generally nine groups of cold pressing roller groups, which are evenly spaced together with the previous six groups of traction roller groups 3 on the frame 1. The structure and connection method of the cold pressing roller group are similar to those of the traction roller group 3, except that the cold pressing roller group participates in the transmission with the help of the transmission steel plate 6, and there is no need for an independently set transmission component.

[0032] There are also installation grooves 11 that pass through the left and right sides of the frame 1 corresponding to the traction roller group 3 or the cold pressing roller group. A screw seat 13 is provided at the top of the installation groove 11, and a mounting seat 12 that can slide up and down is provided inside the installation groove 11. An adjusting screw 14 that is threadedly connected to the screw seat 13 is passed through the screw seat 13, and the end of the adjusting screw 14 is embedded in the mounting seat 12, which only ensures that the adjusting screw can rotate relative to the mounting seat 12 but cannot move up and down relative to the mounting seat 12, that is, movement in the vertical direction. The adjusting screw 14 must be synchronized with the mounting seat 12. After the mounting seat 12 is fixed in position, a reinforcing nut will be provided on different sides of the screw seat 13 to limit the rotation and displacement of the adjusting screw 14.

[0033] The roller 4 is composed of a plurality of detachable roller segments 41, which are connected by threaded connection or screw connection. There is a margin on the connection between the two ends of the roller 4 and the mounting seat 12, that is, the existing fixation of the roller 4 can be released, and it can be moved to the left or right for a certain length to achieve the removal of a certain roller segment 41, and the corresponding split rollers 42 can be installed as needed to fill the length gap of the original roller segment 41, and reset and reused. Generally, detachable split rollers 42 are added between adjacent roller segments 41 in the cold pressing zone, and they are installed according to the required size and quantity. The above operation can also be performed in the traction section in theory. The number and model of split rollers 42 installed on each roller 4 are not unique and do not need to be symmetrical. That is to say, split rollers 42 of different sizes and models can be installed on the same roller 4, and the number of split rollers 42 on different rollers 4 can be different, and the positions can also be misaligned. Everything is based on actual production needs. The leftmost end of the roller 4 is provided with a main roller 43. Considering the particularity of the position of the main roller 43 and the functionality of assuming the main power transmission, the main roller 43 will be thicker in the horizontal direction than the sub-roller 42, and adopts a left narrow and wide structure, and is overall streamlined, which scientifically and rationally improves the transmission efficiency and protects the components. The traction transmission component 5 outputs power, which is transmitted to the traction roller group 3, driving the two relative rollers 4 to rotate in the opposite direction, transmitting the introduced steel plate 6 backward, and the steel plate 6 in the transmission state drives the cold pressing zone roller group with adjusted spacing to achieve cold pressing. The module of the entire roller 4 is variable, and there is no need to dismantle the entire roller 4, and it is sufficient to adjust two adjacent roller segments 41.

[0034] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
