Description

Technical Field

[0001] This disclosure relates to the field of press technology for can lid production, and more particularly to a worktable structure suitable for presses. Background Technology

[0002] like Figure 1 The diagram shows a partial structural schematic of a press for producing can lids (only a portion of the structure is shown to avoid excessive disclosure). The press has a worktable 10 for mounting the lower mold (not shown), wherein the worktable 10 is directly fastened to the base plate 40 of the forming area 20 of the machine body 30 by screws.

[0003] Regarding the installation style and structure of the aforementioned workbench 10, when designing and constructing the machine body 30, although the can lid itself has a thin wall and the required forming pressure is much smaller than other thick-walled products, directly fastening the pressure-bearing workbench 10 to the base plate 40 is equivalent to directly transferring the pressure to the base plate 40. For presses used to produce can lids, the machine body 30 is generally assembled from metal plates and is not directly die-cast as a whole. This requires the base plate 40, as a component of the machine body 30, to have sufficient pressure-bearing capacity. The base plate 40 is forced to form an ultra-thick plate. In addition, the overall size of the base plate 40 is not small. Thus, the base plate 40 is both thick and large, which naturally increases the cost. More importantly, for the machine body 30, the setting of a single ultra-thick walled large plate is not conducive to the design requirement of uniform wall thickness of the machine body 30.

[0004] Based on this, this disclosure optimizes and improves the design of the workbench structure, including the workbench body and the supporting components. Summary of the Invention

[0005] This disclosure aims to address at least one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, this disclosure provides a workbench structure suitable for a press, including a workbench, a base plate disposed in the forming area of ​​the machine body, and a connecting base. The base plate has a positioning and mounting hole, and a main support plate is symmetrically disposed at the bottom of the base plate near the end of the positioning and mounting hole along the width direction. The connecting base is disposed in the positioning and mounting hole and supported on the main support plate, and the workbench is fastened to the connecting base.

[0007] In one feasible implementation, the bottom of the connecting base has a protruding positioning mounting hole, the main support plate has a main mounting slot, and the part of the connecting base with the protruding positioning mounting hole is located at the main mounting slot and is engaged in the main mounting slot.

[0008] In one feasible implementation, the part of the connecting base with the protruding positioning and mounting hole is provided with symmetrical clamping plates on both sides at the main mounting slot, and the clamping plates are fastened to the main support plate at the main mounting slot.

[0009] Preferably, an elongated connecting hole is provided along the width direction on the main support plate at the main mounting slot, and a circular mounting hole is provided on the card plate to match and connect with the elongated connecting hole.

[0010] Preferably, the card plate is a T-shaped structure that is wider at the top and narrower at the bottom, with the upper and lower parts of the T-shaped structure connected by a concave arc transition.

[0011] In one possible implementation, the connecting base extends outward along its top edge to form an extended edge that overlaps the top of the base plate.

[0012] Preferably, the extended edge is equipped with a downwardly inclined blanking plate along its length, and the blanking plate has limiting stops on both sides.

[0013] In one feasible implementation, the thickness of the base plate and the main support plate is consistent.

[0014] In one feasible implementation, a secondary support plate is symmetrically provided at the bottom of the base plate at the end of the positioning mounting hole along the length direction. The secondary support plate is provided with a secondary mounting slot at the top, and the part of the connecting base end at the secondary mounting slot is engaged in the secondary mounting slot.

[0015] Compared with the prior art, this disclosure has at least the following beneficial effects: The base plate of this disclosure has positioning and mounting holes, and a connecting base and a main support plate are added. The connecting base can be fitted into the positioning and mounting holes and supported by the main support plate, and the worktable can be firmly installed on the connecting base. This realizes the installation of the worktable and avoids the direct fastening to the base plate as in the prior art. As a result, the load of the base plate is distributed by the main support plate, the base plate can be set with normal wall thickness, avoids setting excessively thick walls, and maintains a uniform wall thickness of the entire machine body.

Detailed Implementation

[0026] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0028] Currently, in presses used for producing can lids, the worktable used to install the lower mold is directly fastened to the base plate of the forming area of ​​the machine body with screws. The base plate bears all the loading pressure and is constructed into an ultra-thick wall structure, which increases the overall cost and does not meet the design requirements for uniform wall thickness of the machine body.

[0029] Based on this, the present disclosure provides a worktable structure suitable for a press. The base plate of the present disclosure has positioning and mounting holes, and a connecting base and a main support plate are added. The connecting base can be fitted into the positioning and mounting holes and supported by the main support plate, and the worktable can be fastened to the connecting base. This realizes the installation of the worktable and avoids the direct fastening to the base plate as in the prior art. Thus, the load of the base plate is distributed by the main support plate, and the base plate can be set with normal wall thickness, avoiding excessively thick wall setting and maintaining a uniform overall wall thickness of the machine body.

[0030] The following detailed description of the worktable structure suitable for a press is provided through specific embodiments:

[0031] Reference Figures 1 to 6 As shown, this disclosure provides a workbench structure suitable for a press, including a workbench 10, a connecting base 50, and a base plate 40 disposed in the forming area 20 of the machine body 30. The base plate 40 is a long rectangular plate structure located at the bottom of the forming area 20, with a positioning mounting hole 401 in its middle. The size and shape of the positioning mounting hole 401 match the size and shape of the connecting base 50. At the bottom of the base plate 40 near both ends of the positioning mounting hole 401, main support plates 60 are respectively provided along the width direction, thus forming two main support plates 60. These two main support plates 60 are symmetrically arranged along the length direction of the positioning mounting hole 401 to maintain balanced load-bearing. The connecting base 50 is disposed in the positioning mounting hole 401 and supported on the two main support plates 60, and the workbench 10 is securely mounted on the top of the connecting base 50. It should be noted that the bottom of the two main support plates 60 extends downward to the bottom of the machine body 30, thereby obtaining stable support capacity.

[0032] Based on the optimization and improvement of the workbench structure described above, this disclosure completes the overall installation of the workbench 10. By opening positioning mounting holes 401 on the base plate 40 and adding a connecting base 50 and a main support plate 60, the connecting base 50, which can mount the workbench 10 on top, can be positioned and mounted onto the positioning mounting holes 401 and the main support plate 60. This effectively transfers the load-bearing pressure of the base plate 40 to the main support plate 60, thereby reducing the cost of the base plate 40 from an ultra-thick plate to a conventional thickness. Furthermore, the wall thickness of the base plate 40 can be comparable to the wall thickness of the main support plate 60, making the overall wall thickness of the machine body 30 as uniform as possible. It should be noted that there are two main support plates 60, which are symmetrically arranged along the length of the positioning mounting holes 401, balancing the load-bearing pressure. As long as the workbench 10 is not excessively offset from the connecting base 50, the two main support plates 60 can effectively support and bear the pressure of the connecting base 50. In addition, this disclosure separately adds a connecting base 50. After the worktable 10 is positioned and installed using the connecting base 50, it avoids directly positioning and installing the worktable 10 in the positioning mounting hole 401. As a result, the outer dimensions of the worktable 10 are not limited by the positioning mounting hole 401. Therefore, the connecting base 50 can match worktables 10 of different sizes.

[0033] In this embodiment, to appropriately reduce the load-bearing pressure on the two main support plates 60, and considering that the base plate 40 still has a certain load-bearing capacity after being constructed with a conventional plate thickness, specifically, the connecting base 50 extends outward along its top edge to construct an extended edge 501. The extended edge 501 is attached to the top of the base plate 40, thereby making full use of the load-bearing capacity of the base plate 40. The load-bearing pressure is shared by the base plate 40 and the two main support plates 60, forming a more balanced and distributed load-bearing capacity. The overall structure is more stable and reliable, and the load-bearing capacity is also enhanced.

[0034] Furthermore, since the matching press is used in a fully automated production line, after the can lid is formed in the upper and lower molds, the robot arm picks up the material and puts it into the common conveyor line next to the press. The robot arm is not only responsible for picking up the material from the press, but also for feeding other equipment on the common conveyor line. Therefore, in this embodiment, the workbench 10 is equipped with a downwardly inclined material dropping plate 70 on its side along the length direction. The material dropping plate 70 includes a mounting side 701 and an inclined plate body 702.

[0035] Based on the aforementioned material feeding plate 70, after the robot arm picks up material from the press, it can quickly and directly place the can lid directly into the material feeding plate 70. The material feeding plate 70 itself is inclined, allowing the can lid to fall onto the common conveyor line below under its own weight. This saves the robot arm's unloading time, freeing up time to operate other equipment. It should be noted that after setting the material feeding plate 70, its inclined lower end extends directly above the common conveyor line.

[0036] In this embodiment, the bottom of the connecting base 50 has a protruding positioning mounting hole 401, and the main support plate 60 has a main mounting slot 601. The portion of the connecting base 50 with the protruding positioning mounting hole 401 is located in the main mounting slot 601 and is engaged in the main mounting slot 601. Based on the setting of the main mounting slot 601, the connecting base 50 is engaged in a semi-hugging state. Compared with the connecting base 50 being placed directly on a flat top wall, the semi-hugging engagement structure of this disclosure can more securely position and engage the connecting base 50.

[0037] To ensure that the connecting base 50 is connected to the main support plate 60 as a whole after positioning and mounting, in this embodiment, the portion of the connecting base 50 protruding from the positioning mounting hole 401 is symmetrically provided with clamping plates 80 on both sides of the main mounting slot 601. The clamping plates 80 are fastened to the main support plate 60 at the main mounting slot 601. Specifically, in this embodiment, the fastening connection is preferably achieved in the following manner: an elongated connecting hole 602 is provided along the width direction on the main support plate 60 at the main mounting slot 601, and the clamping plate is provided with a circular mounting hole that matches and connects to the elongated connecting hole.

[0038] This disclosure utilizes the clamping plate 80 to securely connect the connecting base 50 to the top of the main support plate 60, promoting the connection of the connecting base 50 into a single integrated structure and facilitating reliable assembly of the worktable 10. The elongated connecting hole 602 allows for a wide range of options for the placement of the circular mounting hole in the width direction; even a slight offset in the width direction allows for fastening to the elongated connecting hole 602 with bolts and nuts.

[0039] Regarding the structural optimization of the card plate 80, in this embodiment, the card plate 80 is a T-shaped structure that is wider at the top and narrower at the bottom, with the upper and lower parts of the T-shaped structure connected by a concave arc transition. This structure of the card plate 80 has a large span in the upper width direction, resulting in a large contact area with the top of the main support plate 60, which helps to enhance the connection strength. Meanwhile, the lower part narrows in the width direction, preventing the card plate from appearing too large and wasting material. At the same time, the concave arc transition connection eliminates sharp right-angle connections, resulting in a smooth connection and avoiding localized stress concentration caused by right-angle edges.

[0040] In this embodiment, symmetrical secondary support plates 90 are also provided at the bottom of the base plate 40 at both ends of the positioning mounting hole 401, running along the length direction. The secondary support plates 90 are provided with secondary mounting slots 901 at their tops, and the end portion of the connecting base 50 at the secondary mounting slot 901 is engaged in the secondary mounting slot 901. The connecting base 50 of this disclosure is also supported by the secondary support plates 90 at its length end, thereby effectively supporting the connecting base 50 in both its length and width directions.

[0041] Based on the above-mentioned workbench structure, the thickness of the base plate 40, the main support plate 60, and the secondary support plate 90 can be kept consistent, and a plate structure of conventional thickness can be constructed, which is conducive to the formation of a uniform wall thickness of the machine body 30.
