Description

Technical Field

[0001] The utility model relates to the field of die-changing tooling equipment, in particular to a die-changing vehicle. Background Art

[0002] Punch presses are widely used in the stamping industry to manufacture various metal products, such as home appliance components and electronic product casings. These products often require different molds to complete the corresponding stamping process. To meet the production needs of different products, punch presses need to frequently change molds.

[0003] For example, the patent application number 202120808168.0 provides a tower punch die-changing tooling, which includes a movable frame structure, including a frame body, a plurality of universal wheel structures arranged at the bottom of the frame body, and a support plate structure arranged on the frame body; a universal ball array, including a plurality of universal balls, a plurality of said universal balls are fixedly arranged on the support plate structure and arranged in an array; a plurality of detachable guardrails, detachably arranged on the frame body, to provide protection in at least three directions above the support plate structure. This patent can disperse the force borne by the transport structure to the entire support plate, with a large support area, effectively reducing the impact of pressure on the support structure. At the same time, since the guardrail structure of this patent is a detachable structure, the mold can be removed in multiple directions, and the environmental applicability is improved.

[0004] However, the support plate structure and the die in the aforementioned patent are connected by universal wheels. This results in the die being easily offset relative to the support plate structure due to the die's own inertia during the pushing process, especially at the start and end of the pushing process. Although the aforementioned patent includes a guardrail structure, it only prevents the die from completely falling out of the support plate structure. During this period, the guardrail structure and the die may collide and cause damage to the die. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a die-changing vehicle, which retains structures such as a universal ball to facilitate the subsequent transportation of the die to the punching machine, and has made some improvements to ensure that the die does not slide significantly relative to the die-changing vehicle during transportation, thereby ensuring the safety of the die and surrounding construction personnel during transportation.

[0006] The utility model is realized through the following technical solutions:

[0007] A die-changing vehicle comprises: a vehicle body, comprising a base, a supporting plate arranged on the top of the base, and several rollers arranged at the bottom of the base, wherein the base and the supporting plate are connected by several support columns; the supporting plate comprises a supporting surface for supporting the die, and the supporting surface is provided with several universal balls; several detachable limit fences, the detachable limit fence comprises a limit rod and a mounting block arranged at the bottom of the limit rod, and the limit rod is provided with a limit surface that fits the die; wherein, the supporting plate is provided with several mounting openings, and an adaptive first clamping structure is provided between the mounting opening and the mounting block, so that the detachable limit fence can be installed on the vehicle body and limit the die in at least four directions on the supporting surface.

[0008] As a further improvement of the present invention, the limiting rod includes a main rod and a limiting block arranged on the main rod. When the detachable limiting fence is installed, the limiting surface on the limiting block fits and contacts the die.

[0009] As a further improvement of the present invention, the limiting block includes an inclined surface structure, and a first angle is formed between the inclined surface structure and the limiting surface, and the first angle is an acute angle.

[0010] As a further improvement of the present invention, it is characterized in that the limit block is movably installed on the main rod through an installation kit.

[0011] As a further improvement of the present invention, the installation kit includes a clamping block, a clamping opening is provided on the clamping block, a clamping space is provided in the clamping block, the clamping space is connected to the clamping opening, and the clamping space and the clamping opening are adapted to the main rod.

[0012] As a further improvement of the present invention, the outer wall of the clamping block is fixedly connected to the limiting block, and when the limiting surface faces the die, the clamping opening faces downward.

[0013] As a further improvement of the present invention, the mounting block includes two sub-mounting blocks arranged at the bottom of the limit rod and close to the end of the limit rod; four groups of mounting openings are provided on the supporting plate, which are respectively placed at the four corners of the supporting surface, and a single mounting opening includes two mounting sub-openings, and an adaptive second clamping structure is provided between the mounting sub-opening and the sub-mounting block.

[0014] As a further improvement of the present invention, a plurality of connecting blocks are provided on at least one side wall of the supporting plate, for fixing the relative position between the supporting plate and the punch press.

[0015] As a further improvement of the present invention, the plurality of universal balls are distributed in a polygonal array.

[0016] As a further improvement of the present invention, a trolley handle component is also provided on the main body of the changing cart.

[0017] The beneficial effects of the present invention are as follows: first, during transportation, a plurality of detachable limiting rods can come into contact with the die, thereby achieving a limiting and fixing effect on the die placed on the support plate, ensuring that during this period, the die will not slide significantly relative to the support plate due to its own inertia. Secondly, when the die exchange vehicle moves to the designated position next to the punch press, the detachable limiting bar close to the side of the punch press can be removed. At this time, since the die and the support surface are in contact through the universal ball joint, the friction between the two is still small, and the construction personnel can easily push the die directly onto the punch press.

[0029] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0030] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0031] In this embodiment, the bottom of the die is a rectangular parallelepiped structure, so the structures of the various components of the die-changing vehicle provided in this embodiment are compatible with the structure of the die.

[0032] Example 1:

[0033] In this embodiment, if Figures 1 and 2 As shown, the die changing vehicle includes a changing vehicle body 1 and four detachable limit bars 2.

[0034] Among them, such as Figure 1 As shown, the body 1 of the replacement vehicle includes a base 101, a supporting plate 102 arranged on the top of the base 101, and four sets of rollers 103 arranged at the bottom of the base 101. The base 101 and the supporting plate 102 are connected by four support columns 104. In this embodiment, the four support columns 104 are respectively connected to the bottom of the four corners of the supporting plate 102.

[0035] A supporting surface 102-1 is also provided on the supporting plate 102, and a plurality of universal balls 102-2 are installed on the supporting surface 102-1. When the die is placed in the die changing vehicle, the bottom of the die directly contacts the universal balls 102-2, and the friction between the two is small, thus facilitating the rapid loading and unloading of the die on the die changing vehicle. Figure 3 As shown, the supporting plate 102 is also provided with eight mounting openings 102-3, all of which are used to mount the detachable limiting fence 2. Figure 4 As shown, the detachable limit bar 2 includes a limit rod 201 and a mounting block 202 disposed at the bottom of the limit rod 201. The mounting block 202 is adapted to fit within the mounting opening 102-3 and can be inserted into the mounting opening 102-3 from top to bottom. Once inserted, the mounting block 202 is unlikely to deviate horizontally within the mounting opening 102-3. In this embodiment, the mounting block 202 is located in the middle of the limit rod 201.

[0036] In actual use, construction personnel can select different specifications of detachable limit bars 2 according to the different sizes of the die and install them on the appropriate installation opening 102-3. The ultimate purpose is as follows: Figure 5 As shown, it mainly ensures that the limiting surfaces of the four detachable limiting fences 2 can be combined to form a limiting space, which can accommodate the die, but at the same time the four limiting surfaces are all in contact with the die, which ensures that the detachable limiting fence can prevent the die from shifting on the horizontal plane.

[0037] The different specifications of the detachable limiting fence 2 are mainly reflected in the different distances between the upper limit surface of the limiting rod 201 and the mounting block 202 and the different heights of the limiting surface.

[0038] Specifically, the spacing between the limiting surfaces and the mounting block 202 ensures that the limiting surfaces of the detachable limiting fence 2 are aligned with the die when the die is installed. In this embodiment, there are eight mounting openings 102-3, and the positions of the mounting openings 102-3 are relatively fixed. Therefore, when the die is small and is placed far from the mounting openings 102-3, a detachable limiting fence 2 with a larger spacing between the limiting surfaces and the mounting block 202 can be used to ensure that the limiting space formed by the four detachable limiting fences 2 can accommodate and restrain the small die. This further ensures that the die will not shift horizontally relative to the support plate 102 during movement with the die-changing vehicle.

[0039] The role of the limit surface height is mainly reflected in the transportation of large-sized dies. The higher limit surface height ensures that when the four detachable limit bars 2 are installed, there will be a larger contact area between the limit surface and the die. This ensures that the die will not tip over due to its own inertia during the movement with the die-changing vehicle, especially at the start and end of the movement, and effectively enhances the stability of the die placement.

[0040] When the die is transported to the designated location next to the punch press, the construction worker can remove the detachable limit fence 2 closest to the punch press. At this time, since the bottom of the die is directly in contact with the universal ball 102-2, the contact area between the two is small, so the friction is small, and the construction worker can easily push the die to the punch press to complete the final transfer work. Conversely, when the die is unloaded, the construction worker can also easily push the die to the die exchange vehicle to quickly complete the die replacement work.

[0041] Preferably, if Figures 1-3As shown, in this embodiment, two connecting blocks 105 are provided on each of the three side walls of the support plate 102. The connecting blocks 105 are used to fix the relative position between the support plate 102 and the punch press. Therefore, in the structure of this embodiment, the support plate 102 has three directions to facilitate the fixation between the die-changing vehicle and the punch press. That is, the construction personnel can fix the die to the punch press from the front, right, and left sides of the support plate 102, and then can also unload or load the die from these three directions, greatly improving the flexibility of the die-changing vehicle.

[0042] Preferably, if Figure 3 As shown, the universal balls 102-2 are distributed in a rectangular array, which makes the force more uniform when the supporting plate 102 is loaded with a die. In this embodiment, in order to avoid the installation of the detachable limit bar 2, the universal balls 102-2 will not be installed in some positions.

[0043] Preferably, if Figures 1-3 Shown, also be provided with pushcart handle member 106 on the change car main body 1, so that construction personnel promotes the die change car.In the present embodiment, pushcart handle member 106 is arranged at the rear side of supporting plate 102, therefore the loading and unloading work of die is not affected.

[0044] Example 2:

[0045] The difference between this embodiment and embodiment 1 is that, in this embodiment, Figure 6 As shown, the limiting rod 201 includes a main rod 201-1 and two limiting blocks 201-2 arranged on the main rod 201-1. When the detachable limiting fence 2 is installed, it fits and contacts the die through the limiting blocks 201-2, and the limiting surface is formed on the limiting blocks 201-2.

[0046] With this structure, the different sizes of the detachable limiting fence 2 described in Example 1 are reflected in the different sizes of the limiting block 201-2 in this embodiment. Specifically, the length of the limiting block 201-2 in this embodiment affects the distance between the limiting surface and the mounting block 202, while the height of the limiting block 201-2 affects the height of the limiting surface.

[0047] The aforementioned structural changes allow the production of the limiting rod 201 to initially produce a plurality of main rods 201-1 of the same dimensions. Subsequently, limiting blocks 201-2 of varying dimensions can be movably or fixedly mounted on the main rods 201-1 to form detachable limiting fences 2 of varying dimensions. This allows for greater flexibility in the production of the limiting rod 201, enabling faster and more flexible production of detachable limiting fences 2 of desired dimensions using the newly added die.

[0048] Preferably, if Figures 7 and 8As shown, the stop block 201-2 further includes an inclined surface structure 201-2a. This inclined surface structure 201-2a forms a first angle α with the stop surface, and the first angle α is an acute angle. The inclined surface structure 201-2a provides support for the stop surface. In particular, when the die tends to deflect and slide, the inclined surface structure 201-2a can disperse and reduce the impact force on the stop surface, thereby improving the overall support capacity of the detachable stop bar 2.

[0049] Preferably, the limit block 201-2 is movably mounted on the main rod 201-1 via the mounting kit 201-3. With this structure, during the use of the die-changing vehicle, only four main rods 201-1 of fixed specifications can be machined. By then machining limit blocks 201-2 of different specifications and mounting them on the main rods 201-1, the position fixing requirements for dies of different sizes can be achieved, further reducing the production cost of the die-changing vehicle while also increasing its flexibility.

[0050] Preferably, if Figures 7 and 8 As shown, the installation kit 201-3 includes a clamping block 201-3a, a clamping opening 201-3b is defined on the clamping block 201-3a, and a clamping space 201-3c is defined in the clamping block 201-3a. The clamping space 201-3c is connected to the clamping opening 201-3b. The clamping space 201-3c and the clamping opening 201-3b are adapted to the main rod 201-1. Specifically, the clamping opening 201-3b can allow the main rod 201-1 to pass through and be placed in the clamping space 201-3c, while the clamping space 201-3c can accommodate the main rod 201-1 and form a clamping effect to fix the limit block 201-2. This structure is more conducive to the rapid replacement of the limit block 201-2.

[0051] Preferably, if Figures 7 and 8 As shown, the outer wall of the clamping block 201-3a is fixedly connected to the limit block 201-2. When the limit surface faces the die, the clamping opening 201-3b faces downward. Under this structure, the clamping block 201-3a opens downward and can be directly installed on the main rod 201-1 from top to bottom in the vertical direction.

[0052] On the one hand, this structure allows construction workers to first install the main rod 201-1 during the process of limiting and fixing the die, and then select the limiting block 201-2 of appropriate size and install it on the main rod 201-1, which optimizes the process of limiting and fixing the die, reduces the trial and error time cost of selecting the limiting block 201-2, and speeds up the limiting and fixing speed of the die.

[0053] On the other hand, with this structure, the fixed position of the die on the support plate 102 is more variable, and the combination with the connecting block 105 can further speed up the replacement of the die. Specifically, after the die is placed on the support plate 102, the construction personnel can first install the remaining components of the detachable limit fence 2 except the limit block 201-2; then adjust the relative position of the die and the connecting block 105; finally, without changing the position of the die, select and install the limit block 201-2 of appropriate specifications based on the distance between the die edge and the main rod 201-1 to complete the limit and fixation of the die.

[0054] When the die is replaced, the newly replaced die needs to be placed in the corresponding position of the punch press and then fine-tuned. The friction force encountered by the die when moving on the punch press is large, so fine-tuning is usually time-consuming and inconvenient. In the structure of this embodiment, since the connecting block 105 is used to fix the relative position between the supporting plate 102 and the punch press, the position of the die is properly adjusted based on the connecting block 105, and the supporting plate 102 and the punch press are fixed. The position of the die and the punch press are already adapted. At this time, after the die is pushed into the punch press, the subsequent fine-tuning operation of the die position can be minimized, thereby reducing the overall time spent on changing the die.

[0055] At the same time, if Figure 9 As shown in , if the die is pushed out from side A, the limit blocks 201-2 on sides B and D always maintain a clamping effect on the die during the pushing process, which actually plays a partial guiding role, further avoiding the deviation of the moving path of the die during the pushing process and increasing the workload of subsequent fine-tuning.

[0056] Preferably, if Figure 10 As shown, the mounting block 202 includes two sub-mounting blocks 202-1 disposed at the bottom of the limiting rod 201 and near the end of the limiting rod 201; the supporting plate 102 is provided with four groups of mounting openings 102-3, each group of mounting openings 102-3 including two mounting sub-openings 102-3-1. The mounting sub-openings 102-3-1 are adapted to the sub-mounting blocks 202-1, and the sub-mounting blocks 202-1 can be smoothly inserted into the mounting sub-openings 102-3-1 without shifting in the horizontal plane within the mounting sub-openings 102-3-1. In this embodiment, when the limiting block 201-2 is squeezed by the die, the impact force can be transmitted to the main rod 201-1, and the main rod 201-1 disperses the impact force to both ends, reducing the impact force on the individual sub-mounting blocks 202-1, enhancing the overall impact resistance of the detachable limiting fence 2, and improving the limiting and fixing effect on the die.

[0057] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
