Technical Field
[0001] The utility model relates to the technical field of shearing machines, in particular to a shearing piece collecting device for shearing machines. Background Art
[0002] Shearing machine is a device that uses a movable upper blade and a fixed lower blade to shear metal plates. Most of the plates required for the tricycle frame are first sheared by the shearing machine. During the shearing operation, the original plate is manually fed from the feeding platform on the shearing machine. The original plate is pressed against the rear stop mechanism for length positioning. After pressing the start switch, the upper blade is driven down to shear the original plate; the sheared pieces fall into the shearing machine. In order to facilitate the collection and transportation of sheared pieces, such as Fig.10 As shown, the inventors set up a discharge ramp below the shearing position, and placed a turnover box for collection at the lower end of the discharge ramp. The sheared pieces slide down along the discharge ramp into the turnover box to be collected. However, in actual use, it was found that the cut sheared pieces would only be randomly stacked at one end of the turnover box close to the discharge ramp, and the other positions in the turnover box were empty, and the turnover box was obviously overweight as a whole. Because the sheared pieces are metal workpieces with heavy weight, it is not easy to spread the disorderly stacked sheared pieces manually, so the turnover box can only be transferred by a forklift in a heavy state with one end full of sheared pieces. The forklift forking process is prone to the risk of overturning the box due to the overweight, and the fork picking is difficult, and the turnover box space is obviously wasted, and the turnover frequency increases. For this reason, it is necessary to further improve the collection method of the sheared pieces to improve the above situation. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a shearing piece collecting device for a shearing machine, which can significantly reduce the generation of eccentric weight, facilitate smooth forking, and has a high turnover box space utilization rate, thereby helping to reduce the turnover frequency.
[0004] In order to solve the above technical problems, the technical solution of the utility model is: a shearing piece collection device for a shearing machine comprises a discharging inclined platform fixedly arranged in the shearing machine and located below the shearing mechanism, a horizontally arranged fixed guide platform is fixedly arranged in the shearing machine and located directly below the discharging inclined platform, a movable guide platform with a pitch and swing setting is installed on the end of the fixed guide platform extending out of the lower end of the discharging inclined platform, an elastic supporting mechanism is connected at the free end of the movable guide platform, and a horizontal limiting structure is provided between the movable guide platform and the fixed guide platform; a fixed side guide rail is installed on the fixed guide platform, a movable side guide rail corresponding to the fixed side guide rail is installed on the movable guide platform, a collecting trolley is installed on the movable side guide rail and the fixed side guide rail, and the collecting trolley is used to carry a turnover box.
[0005] As a preferred technical solution, the elastic support mechanism includes a support seat fixedly arranged relative to the shearing machine, a support screw is fixedly provided on the support seat, a support screw sleeve is installed on the support screw, and a support spring is installed between the support screw sleeve and the bottom surface of the movable guide platform.
[0006] As a preferred technical solution, the horizontal limit structure includes horizontal limit end surfaces respectively arranged at the proximal ends of the movable guide platform and the fixed guide platform, and the horizontal limit end surface on the movable guide platform is used to abut against the horizontal limit end surface on the fixed guide platform when the movable guide platform is horizontal.
[0007] As a preferred technical solution, an anti-drop-out platform for preventing the collecting trolley from falling out is fixedly provided on the free end of the movable guide platform.
[0008] As a preferred technical solution, the fixed side guide rail is a fixed side strip fixedly welded on the fixed guide platform, and the movable side guide rail is a movable side strip fixedly welded on the movable guide platform.
[0009] As a preferred technical solution, the collection trolley includes a bearing platform, and wheel ear plates are fixedly welded on both sides of the bearing platform, and the trolley wheels are rotatably mounted on the wheel ear plates.
[0010] Due to the adoption of the above technical solution, the shearing machine sheared piece collection device includes a discharge ramp fixedly arranged in the shearing machine and located below the shearing mechanism, a horizontally arranged fixed guide platform is fixedly arranged in the shearing machine and located directly below the discharge ramp, a movable guide platform with a pitching and swinging arrangement is installed on the end of the fixed guide platform extending out of the lower end of the discharge ramp, an elastic support mechanism is connected to the free end of the movable guide platform, and a horizontal limiting structure is provided between the movable guide platform and the fixed guide platform; a fixed side guide rail is installed on the fixed guide platform, a movable side guide rail corresponding to the fixed side guide rail is installed on the movable guide platform, a collection trolley is installed on the movable side guide rail and the fixed side guide rail, and the collection trolley is used to carry the turnover box arrangement. The utility model adds a fixed guide platform and a movable guide platform in the shearing machine, and elastically supports them with the elastic support mechanism. After the turnover box is delivered, it is first placed on the collection trolley, and then pushed directly under the discharge ramp, so that only one end of the turnover box is exposed outside the discharge ramp, and the collection trolley spans between the movable guide platform and the fixed guide platform. The gravity torque of the turnover box and the collection trolley at this time is not enough to overcome the elastic force torque of the elastic support mechanism, so the movable guide platform is in a horizontal state, and the outer end position of the turnover box is used to collect the shearing pieces that slide down the discharge ramp. After a certain amount of shearing pieces are stacked at the outer end of the turnover box, its gravity torque increases to a level greater than the elastic force torque of the elastic support mechanism, and the movable guide platform swings forward, and the collection trolley starts to move along the inclined movable guide platform. During this process, the middle part of the turnover box will receive a small amount of shearing pieces, and finally the outer end of the collection trolley reaches the free end of the movable guide platform and stops, and the inner end of the turnover box is at the discharge ramp to continue receiving shearing pieces. Finally, the outer and inner ends of the turnover box are significantly stacked with sheared pieces, which significantly reduces the problem of weight imbalance and facilitates smooth forking. The turnover box can collect sheared pieces about twice the original weight at a time, which has high space utilization and helps reduce turnover frequency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.
[0024] like Figures 1 to 9As shown together, the shearing piece collection device of the shearing machine includes a discharge ramp 2 fixedly arranged in the shearing machine 1 and located below the shearing mechanism. The discharge ramp 2 is usually formed by a steel plate with a large surface area fixed in the shearing machine 1 by fixed welding or bolt connection. This is a well-known technology and will not be repeated here. Based on the large opening on the main back of the shearing machine 1, when the discharge ramp 2 is set, this embodiment takes the space enclosed between the discharge ramp 2 and the shearing machine 1 as the inner side, and the outer space as the outer side, so as to define the end of the turnover box 3 in this embodiment in the inner space as the inner end, and the end in the outer space as the outer end, so as to achieve the purpose of clearly explaining the structural principle, but not to limit the scope of protection.
[0025] A horizontally arranged fixed guide platform 4 is fixedly provided in the shearing machine 1 directly below the discharging inclined platform 2. A movable guide platform 5 with a pitching and swinging arrangement is installed on the end of the fixed guide platform 4 extending out of the lower end of the discharging inclined platform 2. An elastic support mechanism 6 is connected to the free end of the movable guide platform 5. A horizontal limit structure 7 is provided between the movable guide platform 5 and the fixed guide platform 4; a fixed side guide rail 41 is installed on the fixed guide platform 4, and a movable side guide rail 51 corresponding to the fixed side guide rail 41 is installed on the movable guide platform 5. A collection trolley 8 is installed on the movable side guide rail 51 and the fixed side guide rail 41, and the collection trolley 8 is used to carry the turnover box 3.
[0026] When in use, the turnover box 3 is placed on the collection trolley 8 by a forklift or other equipment, and the collection trolley 8 is pushed under the discharge ramp 2 by manpower or by using the fork on the forklift. Figure 2 As shown, only the outer end of the turnover box 3 is exposed outside the discharge ramp 2, and the collecting trolley 8 is in a state of straddling the movable guide platform 5 and the fixed guide platform 4 at the same time. When no shearing pieces 9 are collected or a small number of shearing pieces 9 are collected, the gravity torque of the turnover box 3 and the collecting trolley 8 is not enough to overcome the elastic force torque of the elastic support mechanism 6, so the movable guide platform 5 is in a horizontal state, and the outer end position of the turnover box 3 is used to collect the shearing pieces 9 that slide down the discharge ramp 2. After a certain amount of shearing pieces 9 are stacked at the outer end of the turnover box 3, its gravity torque increases to a level greater than the elastic force torque of the elastic support mechanism 6, as shown in FIG. Figure 6 As shown, the movable guide platform 5 swings in a downward direction, and the collecting trolley 8 starts to move along the inclined movable guide platform 5. In this process, Figure 8 As shown, the middle of the turnover box 3 will receive a small amount of sheared pieces 9, and finally the outer end of the collecting trolley 8 reaches the free end of the movable guide platform 5 and stops, and the inner end of the turnover box 3 is at the discharge ramp 2 to continue receiving the sheared pieces 9. Fig. 9As shown, the outer and inner ends of the turnover box 3 are significantly stacked with shear pieces 9, so there is no obvious weight imbalance when the forklift picks them up, which facilitates smooth forking. In addition, the turnover box 3 can collect shear pieces 9 of about twice the original weight at one time, which has high space utilization and helps reduce turnover frequency.
[0027] The elastic support mechanism 6 is used to elastically support the free end of the movable guide platform 5, and can be pressed down after the shearing pieces 9 of a specified weight are stacked at the outer end of the turnover box 3. The elastic support mechanism 6 of this embodiment includes a support seat 61 fixedly arranged relative to the shearing machine 1, and the support seat 61 can be directly fixed on the ground with anchor bolts; a support screw 62 is fixedly arranged on the support seat 61, and a support screw sleeve 63 is installed on the support screw 62, and a support spring 64 is installed between the support screw sleeve 63 and the bottom surface of the movable guide platform 5.
[0028] The horizontal limit structure 7 is used to rigidly limit the movable guide platform 5 to be in a horizontal state when the movable guide platform 5 is driven to be upward by the elastic force. The horizontal limit structure 7 of this embodiment includes horizontal limit end faces respectively arranged at the proximal ends of the movable guide platform 5 and the fixed guide platform 4. The horizontal limit end face on the movable guide platform 5 is used to abut against the horizontal limit end face on the fixed guide platform 4 when the movable guide platform 5 is horizontal. The rigid limit is formed by the abutment of the end faces. This rigid limit method is simple and easy to implement.
[0029] In the above structure, the height position of the support screw sleeve 63 can be adjusted by rotating it, so that the support spring 64 generates different initial spring forces. When not collected and used, the initial spring force cooperates with the horizontal limit structure 7 to keep the movable guide platform 5 in a horizontal state. By adjusting this spring force to the required spring force, it is easy to overcome this spring force and realize the tilting swing of the movable guide platform 5 after the outer end of the turnover box 3 is stacked with the shearing pieces 9 of the required weight; the adjustment of the above required spring force can be achieved by rotating the support screw sleeve 63 when the shearing pieces 9 are collected at the outer end of the turnover box 3 and the required weight is reached, until the movable guide platform 5 is observed to swing tilted, and no further adjustment is required afterwards. This spring force adjustment can be obtained by those skilled in the art in combination with the description and conventional technical means, and will not be repeated here.
[0030] The fixed side guide rail 41 in this embodiment is a fixed side strip fixedly welded on the fixed guide platform 4, and the movable side guide rail 51 is a movable side strip fixedly welded on the movable guide platform 5. Both the fixed side strip and the movable side strip can be formed by cutting out long strips of steel and welding them on the corresponding guide platforms, and the structure is simple and easy to implement.
[0031] The collection trolley 8 includes a load-bearing platform 81, and wheel lugs 82 are fixedly welded on both sides of the load-bearing platform 81, and trolley wheels 83 are rotatably mounted on the wheel lugs 82. With this simple trolley structure, the load-bearing platform 81 is at a relatively low height, so that the discharging ramp 2 can maintain a good inclination angle, which facilitates the placement of the turnover box 3 under the discharging ramp 2. The trolley wheels 83 on both sides should be between the guide rails on both sides or outside the guide rails on both sides, so that the guide rails play a guiding role.
[0032] Preferably, an anti-dropping platform 52 is fixedly provided on the free end of the movable guide platform 5 to prevent the collecting trolley 8 from falling out, so as to avoid the collecting trolley 8 moving out of the movable guide platform 5 when moving outward, thereby ensuring that the inner end of the turnover box 3 can finally continue to collect the sheared pieces 9 at the discharge ramp 2.
[0033] In this embodiment, the fixed guide platform 4 and the movable guide platform 5 form a platform, so that after the outer end of the turnover box 3 collects the shearing pieces 9 of specified weight, it can move outward automatically, so as to achieve the purpose of collecting more shearing pieces 9 at both the inner and outer ends of the turnover box 3, so that the problem of unbalanced weight of the turnover box 3 when forking is significantly reduced, and the single collection amount is significantly increased, which is conducive to reducing the turnover frequency.
[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
