Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment, and in particular to an automobile parts stamping equipment for quickly replacing dies and a replacement method thereof. Background Art

[0002] Auto parts are the various units that constitute the overall processing of auto parts and the products that serve the processing of auto parts. In the production of auto parts, a large amount of stamping technology is needed for production, and stamping equipment is needed to control the stamping die to process the material into parts or semi-finished products. In the stamping process, the stamping die is generally installed on the workbench of the stamping equipment, and the upper and lower dies of the die are respectively connected to the upper and lower slides of the punch press by tightening the pressure plate, so that the sheet material is then placed between the upper and lower dies, and the upper die is moved down and combined with the lower die through the punch press to make the product. In actual work, the cost of stamping equipment is relatively high. One stamping equipment corresponds to one die, which will cause waste of resources and increase costs. Therefore, according to production needs, the die on a stamping equipment needs to be replaced frequently to correspond to the production of different products.

[0003] In the prior art, when replacing the mold, the mold is generally required to be placed in the middle position on the workbench. In particular, when placing the continuous mold, since one side of the continuous mold needs to step the material belt, the feed end of the continuous mold needs to be aligned with the feeding device, and the continuous mold needs to be straightened to avoid the continuous mold from tilting, so that the material belt can be smoothly fed in. When replacing the existing mold, the mold is generally picked up by a forklift and placed on the workbench of the punch press. However, due to the limitations of the forklift placement, the mold can only be placed in an approximate position, and then it needs to be further moved manually to put the mold in place. However, due to the heavy weight of the mold, it is difficult to operate manually when moving the mold, which affects the efficiency of mold installation.

[0004] In view of the above technical problems, the present invention discloses an automobile parts stamping equipment for quickly replacing molds and a replacement method thereof. The present invention has the advantages of setting a guide block, so that after a forklift places the mold on the table of a punch press, the mold can be guided to the placement position and the mold can be straightened by pressing down the upper slider, without the need for manual movement, avoiding the mold being too heavy and making it difficult for manual movement, thereby improving the mold replacement speed and the like. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an automobile parts stamping equipment for quickly replacing molds, so as to solve the problem that in the prior art, when the existing mold is replaced, the mold is generally picked up by a forklift and placed on the workbench of the punch press. The placement limitation of the forklift means that the mold can only be placed in an approximate position, and then it needs to be further moved manually to put the mold in place. Since the mold is heavy, it is difficult to operate when manually moving the mold, which affects the efficiency of mold installation. The present invention has the advantages of setting a guide block, so that after the forklift places the mold on the table of the punch press, the mold can be guided to the placement position and the mold can be straightened by pressing down the upper slider, without the need for manual movement, avoiding the mold being too heavy and making it difficult to move the mold manually, thereby improving the speed of mold replacement.

DETAILED DESCRIPTION

[0017] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given. However, the protection scope of the present invention is not limited to the following embodiments. In the description of the present invention, words indicating directions or positional relationships such as "front", "rear", "left", and "right" are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0018] The embodiment discloses an automobile parts stamping equipment with a quick die change, such as Figure 1-Figure 7 As shown, it includes a punch press 1 and a guide mechanism 2 arranged on the table of the punch press 1, wherein Figure 1 As shown, the punch press 1 includes a body 101, a slider component 102, a connecting platform 103, a guide rail component 104, a workbench 105 and a stamping die 106. The body 101 is used to support and connect other components of the punch press 1, and the slider component 102 is a component that cooperates with the die, and its up and down movement can punch the metal material into different shapes. The body 101 is provided with other driving components for controlling the up and down movement of the slider component 102, such as transmission components, control components, cylinder components and lubrication components, which are all prior arts and are not described one by one here. The up and down movement of the slider component 102 is limited by the guide rail component 104, and a connecting platform 103 for fixedly connecting the upper die 161 of the die is provided below the slider component 102, and a workbench 105 is provided below the connecting platform 103. The workbench 105 is fixedly connected to the body 101, and the workbench 105 is in a fixed state. The stamping die 106 is installed on the workbench 105; In actual operation, the upper die 161 of the mold is connected to the connecting platform 103 above through the fastening plate 3, and the lower die 162 is connected to the workbench 105 through the fastening plate 3. Then, when the punch press 1 is running, the slider component 102 moves up and down to drive the upper die 161 of the mold to move up and down, and the lower die 162 is fixed on the workbench 105. When the upper die 161 moves downward, it is combined with the lower die 162 to punch and process the material sheet. When the upper die 161 moves upward, the upper and lower dies 162 are separated, and the manufactured product is taken out to complete the processing.

[0019] like Figure 1-Figure 3As shown, the stamping die 106 includes an upper die 161, a lower die 162, an upper pad 163, a lower pad 164 and a lower pad 165, wherein the upper die 161 is detachably connected to the upper pad 163 by screws, and both sides of the upper pad 163 are provided with key slots 12 for fastening the pressure plate 3, and the lower die 162 is also detachably connected to the lower pad 164 by screws, and there are three lower pads 164, with space left between the lower pads 164 for the forklift of the forklift to be inserted, and the space between the lower pads 164 can be used for waste discharge, and in addition, the lower pad 164 is connected to the lower pad 165 by screws, and both sides of the lower pad 165 are also provided with key slots 12.

[0020] It should be noted that both the connecting platform 103 and the workbench 105 are provided with pressure plate grooves 4 for plugging in the screws of the fastening pressure plate 3, and there are two groups of pressure plate grooves 4 on the connecting platform 103, which are specifically located on both sides of the connecting platform 103. The pressure plate grooves 4 on the connecting platform 103 pass through its lower end face and front and rear end faces, while the pressure plate grooves 4 on the workbench 105 pass through its upper end face and both side end faces.

[0021] In actual work, when the stamping die 106 is installed, the stamping die 106 is generally forked by a forklift and placed on the workbench 105. Then the staff uses a tool such as a crowbar to further move the die by manpower, so that the stamping die 106 is straightened and moved to the placement position. For example, when placing the continuous die, the feed port of the continuous die is aligned with the feeding device on one side of the punch press 1. After the placement is completed, the staff first adjusts the height of the slider component 102 so that after the slider component 102 moves to the lower limit, the distance between the connecting table 103 and the workbench 105 is consistent with the height of the stamping die 106. The heights are matched, so that after the connecting platform 103 moves to the lower limit, the connecting platform 103 can contact the upper end surface of the stamping die 106, and the convex and concave dies of the upper die 161 and the lower die 162 are clamped, and then the upper die 161 is connected to the connecting platform 103 by tightening the pressing plate 3, and then the lower die 162 is connected to the workbench 105 by tightening the pressing plate 3, so that the upper and lower dies 162 will not be offset after separation, and further displacement of the stamping die 106 by manual operation will be difficult to operate due to the heavy weight of the stamping die 106, affecting the efficiency of die replacement, in order to improve the installation speed of the stamping die 106; In this embodiment, by setting the guide mechanism 2, after the stamping die 106 is forked by a forklift and placed on the workbench 105, there is no need to manually move the stamping die 106. The staff can directly adjust the slider component 102, and then move the slider component 102 downward, so that the connecting table 103 moves down and contacts the upper surface of the stamping die 106. In this process, through the setting of the guide block 201, the stamping die 106 can be further displaced with the help of the downward movement of the slider component 102, so that the stamping die 106 can be straightened and moved to the placement position, thereby completing the installation of the die, avoiding the operator's lack of strength to move the stamping die 106 and affecting the replacement efficiency.

[0022] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the guide mechanism 2 includes a guide block 201 and a plug-in block 202, wherein the guide block 201 is arranged below the connecting platform 103 and connected to the connecting platform 103, and the guide block 201 is located below the connecting platform 103 close to its front end face, and the guide block 201 is arranged to have a right-angled trapezoidal cross section, but the inclined surface thereof faces downward, and more specifically, the front end face, rear end face, and upper end face of the guide block 201 are all planes, and the lower end face of the guide block 201 is arranged to be an inclined surface, and the inclined surface of the lower end face of the guide block 201 is configured to extend from the lowest point of the front end face of the guide block 201 toward the high position of the rear end face, so that when the slider component 102 moves downward to drive the connecting platform 103 to move downward, the inclined surface of the lower end face of the guide block 201 can contact the edge where the upper end face and the front end face of the stamping die 106 intersect, so that the guide block 201 moves downward while the stamping die 106 moves backward, thereby allowing the operator to easily move the stamping die 106.

[0023] It should be noted that, in other embodiments, the guide block 201 may be installed below the connecting platform 103 at a position close to the rear end surface, so that during operation, if the stamping die 106 needs to be moved forward, the guide block 201 only needs to be installed at the rear end of the stamping die 106, with the inclined surface facing the direction of the stamping die 106; It should also be noted that when it is necessary to move the guide block 201 downward so as to displace the stamping die 106, the punch press 1 device needs to be adjusted to the inching mode, and then the operator can press the operation button to allow the connecting table 103 to move downward in an inching manner, making the installation of the stamping die 106 more stable. In addition, it is also possible to slow down the downward movement speed of the slider component 102 of the punch press 1 device.

[0024] Therefore, it is necessary to make the guide block 201 detachable. In order to facilitate the installation and removal of the guide block 201, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a plug-in block 202 is fixedly arranged above the guide block 201, and the cross-section of the plug-in block 202 is set to be convex, and a plug-in slot 5 for the plug-in block 202 to be plugged in is opened inside the connecting platform 103, and the plug-in block 202 is slidably plugged into the plug-in slot 5. It should be noted that the plug-in slot 5 is set to be in an inverted convex shape, and then the plug-in block 202 is limited when it is plugged into the plug-in slot 5 and cannot fall, and the plug-in slot 5 runs through the two side end surfaces of the connecting platform 103 and the lower end surface of the connecting platform 103, that is, the plug-in slot 5 is horizontally opened on the connecting platform 103, and the plug-in block The front and rear end faces of 202 are respectively fitted and slidably matched with the front and rear inner walls of the plug-in slot 5. Therefore, when the plug-in block 202 is plugged into the plug-in slot 5, since the guide block 201 moves downward and contacts the edge of the stamping die 106 to push the stamping die 106 forward and backward, the force exerted on the guide block 201 is in the front-to-back direction. Therefore, the guide block 201 will not move forward and backward through the limiting of the plug-in block 202 and the plug-in slot 5, and the installation and disassembly of the plug-in block 202 is also facilitated by the lateral plug-in. The installation can be completed by simply plugging the plug-in block 202 into the plug-in slot 5.

[0025] In addition, the number of the plug-in slots 5 is set to at least two. In the present embodiment, the number of the plug-in slots 5 is set to three, and the three plug-in slots 5 are all opened on the connecting platform 103 close to the front end surface, and the three plug-in slots 5 are arranged equidistantly along the front and rear directions of the connecting platform 103. Thus, by setting a plurality of plug-in slots 5, the position of the guide block 201 can be adjusted to cover more areas, so that when the stamping die 106 is placed, the placement area is larger, and the cross-sectional shape and size of the pressure plate slot 4 are set to be the same as the plug-in slot 5, so that the fastening pressure plate 3 can also be installed through the plug-in slot 5, and the pressure plate slot 4 can also be installed with the guide block 201.

[0026] Correspondingly, a plug-in slot 5 (not shown in the figure) is provided at the rear end of the connecting platform 103 , so that the guide block 201 can be installed at the rear end below the connecting platform 103 .

[0027] When the stamping die 106 is placed by a forklift, in order to facilitate the rapid placement of the stamping die 106, such as Figure 1-Figure 2As shown, a marking area 13 is also provided on the upper end surface of the workbench 105. Specifically, the marking area 13 is set as a color coating area and is a rectangular mark, and the marking area 13 is set on the upper end surface of the workbench 105 close to its front end surface, and the marking area 13 corresponds to the position of the upper plug-in slot 5. More specifically, when the plug-in block 202 of the guide block 201 is plugged into the plug-in slot 5 at the front end of the connecting platform 103, the front end edge line of the marking area 13 is aligned with the front end surface of the guide block 201 at this time, and when the plug-in block 202 of the guide block 201 is plugged into the plug-in slot 5 at the front end of the connecting platform 103, the front end edge line of the marking area 13 is aligned with the front end surface of the guide block 201 at this time. When the forklift is inserted into the insertion slot 5 at the rear end of the connection platform 103, the rear end edge line of the marking area 13 is aligned with the rear end surface of the guide block 201. In other words, when the forklift is placing the stamping die 106, it is only necessary to place the stamping die 106 within the front end edge line and the rear end edge line of the marking area to ensure that the guide block 201 contacts the upper edge of the stamping die 106 when moving downward, thereby adjusting the displacement of the stamping die 106, facilitating the operation of the forklift when placing the stamping die 106, and improving the replacement speed of the stamping die 106.

[0028] In addition, the distance between the front and rear faces of the guide block 201 is greater than the distance between the center lines of two adjacent plug-in slots 5, so that the stamping die 106 can be gradually moved toward the rear end by changing the position of the guide block 201, so that the moving range of the stamping die 106 is larger.

[0029] Since the stamping die 106 needs to be adjusted in the rear end direction as well as in the left and right directions on the workbench 105, so that the stamping die 106 can be in the best installation position, in order to complete the position adjustment of the stamping die 106 in one step when the slider component 102 moves downward, as shown in FIG. Figure 2 , Figure 6 and Figure 7 As shown, a guide plate 6 is provided at the rear end of the lower pad 165 of the lower die 162, and correspondingly, a guide column 9 matching with the guide plate 6 is provided on the workbench 105; Specifically, the guide plate 6 is used to make the stamping die 106 move laterally by cooperating with the guide column 9 when the stamping die 106 moves backward. Further, the guide plate 6 is in a right-angle trapezoidal shape in a top view, and the rear end surface of the guide plate 6 is set as an inclined surface, the left side of the guide plate 6 is a short side, and the right side is a long side, and the guide plate 6 and the lower pad 165 are set to be movably connected. In addition, the guide column 9 and the workbench 105 are also set to be movably connected; More specifically, a limiting plug block 8 is fixedly provided on the front end face of the guide plate 6, and a limiting slot 7 which is plugged into and cooperates with the limiting plug block 8 is provided on the rear end face of the lower pad 165, and the limiting slot 7 passes through the upper and lower end faces and the rear end face of the lower pad 165, and the top views of the limiting slot 7 and the limiting plug block 8 are both set to a convex shape, and then through the cooperation of the limiting plug block 8 and the limiting slot 7, the guide plate 6 and the lower pad 165 are movably connected and laterally limited, and a socket 10 is provided on the upper end face of the workbench 105, and correspondingly, a plug-in column 11 is fixedly provided on the bottom end of the guide column 9, and the plug-in column 11 is movably plugged into and cooperates with the socket 10, and in addition, the outer diameter of the plug-in column 11 is smaller than the outer diameter of the guide column 9, so that the guide column 9 can be movably connected to the workbench 105.

[0030] Therefore, when the stamping die 106 moves backward under the guidance of the guide block 201 , the contact between the inclined surface of the guide plate 6 and the guide column 9 causes the stamping die 106 to move laterally synchronously, thereby adjusting the position of the stamping die 106 .

[0031] It should be noted that there are at least two limit slots 7. In the present embodiment, there are three limit slots 7, and the three limit slots 7 are arranged equidistantly along the length direction of the stamping die 106. By setting the three limit slots 7, the position of the guide plate 6 can be adjusted, so that the horizontal placement area is larger when the forklift places the stamping die 106.

[0032] It should also be noted that when the stamping die 106 is placed by a forklift, the stamping die 106 is at the front end above the workbench 105, so that when the position is adjusted laterally, it is only necessary to move the stamping die 106 backward for adjustment. Correspondingly, in the horizontal position, the stamping die 106 is located on the left side above the workbench 105, and then when the position is adjusted laterally, it is only necessary to move the stamping die 106 in one direction to increase the replacement speed.

[0033] A method for replacing a stamping device for automobile parts with a quick die replacement method comprises the following steps: Step 1: Remove the stamping die 106 that needs to be replaced from the workbench 105 by a forklift, and place the stamping die 106 that needs to be produced later on the workbench 105 by a forklift, and when placing the stamping die 106, make the edge of the front bottom of the stamping die 106 be in the marking area; Step 2: Adjust the height of the slider of the slider component 102 of the punch press 1 according to the height of the punching die 106, and adjust the mode of the punch press 1 to the inching mode; Step 3: Install the guide block 201 under the connecting platform 103 through the plug-in block 202, and make the inclined surface face the upper edge of the front end of the stamping die 106, and plug the guide column 9 into the inside of the plug hole 10, and then connect the guide plate 6 to the bottom plate 165 through the cooperation of the limiting plug block 8 and the limiting slot 7, and make the inclined surface of the rear end of the guide plate 6 face the guide column 9; Step 4: Press the control button to make the slider component 102 move downward in a jog manner, so that the connecting platform 103 drives the guide block 201 to move downward. The guide block 201 moves downward and moves the stamping die 106 backward through the contact between the inclined surface and the upper edge of the stamping die 106. At the same time, when the stamping die 106 moves backward, the contact between the guide plate 6 and the guide column 9 makes the stamping die 106 move laterally, and then the position of the stamping die 106 is adjusted. It should be noted that when the front and rear positions of the stamping die 106 are adjusted, if the lateral position is not in place, the guide block 201 can be installed on one side of the stamping die 106 through the pressure plate slot 4 on the connecting platform 103, and the inclined surface faces the side of the stamping die 106, and then the stamping die 106 is guided and moved laterally through the guide block 201. After the adjustment is completed, remove the guide block 201, the guide plate 6 and the guide column 9.
