Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of leather punching machines, and particularly relates to a double-group five-head leather punching machine. Background Art
[0002] The dual-group, five-head leather punching machine combines CNC, electronics, and software technologies. Through high-precision mechanical components and an advanced control system, it enables fast and precise punching of materials like leather. Its dual-group design allows two stations to operate simultaneously or alternately, significantly improving production efficiency. Furthermore, the five-head configuration means each station can perform five punching operations simultaneously, further increasing processing speed.
[0003] The dual-group, five-head leather punching machine features a dedicated support plate to stably support the leather during processing. During operation, the leather is first placed on this support plate. A worker then carefully moves the leather along the plate until it reaches the bottom of the punch head, ensuring precise punching.
[0004] However, it's worth noting that the placement plate design of some dual-group, five-head leather punching machines currently on the market has a significant shortcoming: they lack a mechanism to effectively limit the movement of the leather. This design deficiency presents significant operational challenges. If the operator isn't careful when pushing the leather, or if other external factors interfere, the leather's feeding path can easily deviate.
[0005] Even the slightest deviation in this trajectory can significantly impact the final punching result. It can lead to inaccurate punch placement, holes that don't match the intended shape and size, and even damage or waste the leather material. All of these issues ultimately result in a product that fails to meet established quality standards, impacting not only its aesthetics and practicality but also potentially negatively impacting production efficiency and cost control. Utility Model Content
[0006] The purpose of this utility model is to provide a double-group five-head leather punching machine. This machine aims to address a significant shortcoming in the placement plate design of some current double-group five-head leather punching machines on the market: they lack a mechanism to effectively limit the movement trajectory of the leather. This design deficiency presents significant operational challenges. If the operator is not careful when pushing the leather, or if other external factors interfere, the leather's feeding trajectory can easily deviate.
[0007] Even the slightest deviation in this trajectory can significantly impact the final punching result. It can lead to inaccurate punch placement, holes that don't match the intended shape and size, and even damage or waste the leather material. All of these issues ultimately result in a product that fails to meet established quality standards, impacting not only its aesthetics and practicality but also potentially negatively impacting production efficiency and cost control.
[0008] To achieve the above-mentioned object, the present utility model provides the following technical solution: a double-group five-head leather punching machine, comprising a punching machine, wherein a placement plate is installed in the punching area of the punching machine;
[0009] The relevant parameters of the punching machine are as follows:
[0010] Punching speed (holes / minute) is: 2000-2600, number of punch rods: 5x2, number of rotating rods: 5x2, aperture range (mm): 0.8-12, material thickness (mm): 1-6, punching accuracy (mm): ±0.2, machine power (kW): 220v / 3kw, power supply frequency (Hz): 50 / 60, compressed air (bar): 5-6, machine net weight (kg): 1530, machine size (mxmxm): 2.56x1.85x1.6.
[0011] A first slide groove is provided on the surface of one side of the placement plate, and a second slide groove is also provided on the surface of the placement plate near the bottom of the punch end of the punching machine. Adjustment plates are provided on the surfaces of the first slide groove and the second slide groove. An end plate is fixedly installed at one end of the adjustment plate, a bottom plate is fixedly installed at the bottom of the end plate, and an adjustment bolt is installed through the top of the end of the adjustment plate away from the end plate.
[0012] To ensure sufficient lateral movement of the two middle adjustment plates, the first and second chutes are preferably parallel to each other in a double-group five-head leather punching machine of the present invention. Three groups of first and second chutes are provided on the placement plate, and the lateral length of the middle group of first and second chutes is twice that of the first and second chutes on both sides. Two adjustment plates are provided in parallel on the first and second chutes in the middle group of the placement plate.
[0013] In order to enable the adjustment plate to be effectively docked with the placement plate, as a preferred double-group five-head leather punching machine of the present invention, the adjustment plate is located at the bottom of the upper end of the second slide groove and two L-shaped plates are symmetrically installed. The adjustment plate is located at the bottom of the upper end of the first slide groove and is fixedly installed with a slider, and a threaded hole is opened through the adjustment plate between the two L-shaped plates.
[0014] In order to prevent the bottom plate from sinking after long-term use, a double-group five-head leather punching machine is preferably used in the present invention. A sliding tongue is fixedly installed on one side of the bottom plate, and the sliding tongue is movably installed inside the sliding mouth. The sliding tongue is opened on the outer wall of one side of the placement plate.
[0015] In order to enable one end of the adjustment plate to maintain a relatively fixed state with the second slide groove, as a preferred double-group five-head leather punching machine of the utility model, an extrusion head is fixedly installed at the bottom of the adjustment bolt, and the adjustment bolt passes through the threaded hole so that the extrusion head is squeezed on the inner wall of the second slide groove.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] When the leather needs to be punched, the corresponding set of adjustment plates that have been re-adjusted twice are adjusted to a position that matches the width of the leather. The adjustment process is as follows:
[0018] Loosen the adjusting bolt and then move the bottom plate. When the bottom plate moves, it will drive the corresponding adjusting plate to move through the end plate, so that the distance between the two adjustment plates can be adjusted. After the adjustment plate is adjusted, turn the adjusting bolt downward so that the extrusion head at the bottom of the adjusting bolt is squeezed on the inner wall of the second slide groove, so that the adjusted adjustment plate can be fixed. When punching, move the leather along the track formed between the two adjustment plates to the bottom of the punch of the punching machine, so that the structure can achieve the function of precise feeding when in use.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] See also Figure 1-5 The utility model provides the following technical solutions: a double-group five-head leather punching machine, comprising a punching machine 1, a placement plate 2 is installed on the punching area of the punching machine 1, the punching machine 1 is provided with a double-group five-head punch, and a punching area is opened on the placement plate 2 at the bottom of each group of punches;
[0028] A first slide groove 3 is provided on the surface of one side of the placing plate 2, and a second slide groove 8 is also provided on the surface of the bottom of the punch end of the placing plate 2 close to the punching machine 1. An adjustment plate 4 is provided on the surfaces of the first slide groove 3 and the second slide groove 8. An end plate 5 is fixedly installed at one end of the adjusting plate 4, and a bottom plate 6 is fixedly installed at the bottom of the end plate 5. An adjusting bolt 7 is installed through the top of the end of the adjusting plate 4 away from the end plate 5.
[0029] Preferably, the first and second chutes 3, 8 are parallel to each other, and three groups of first and second chutes 3, 8 are provided on the placement plate 2. The horizontal length of the middle group of first and second chutes 3, 8 is twice the length of the side first and second chutes 3, 8. Two adjustment plates 4 are provided parallel to the middle group of first and second chutes 3, 8 on the placement plate 2. An extrusion head 701 is fixedly mounted on the bottom of the adjustment bolt 7. The adjustment bolt 7 extends through the threaded hole 403, causing the extrusion head 701 to press against the inner wall of the second chutes 8.
[0030] When in use, the distance between the two adjustment plates 4 at the bottom of the corresponding punch is adjusted according to the size of the leather with the punch hole. The specific adjustment process of the adjustment plate 4 is as follows:
[0031] Take the longitudinal midline at the bottom of the punch as the center line, measure the dimensions that need to be adjusted of the two adjustment plates 4, and when adjusting, first loosen the adjustment bolt 7 on one of the adjustment plates 4, then move the bottom plate 6. When the bottom plate 6 moves, it will drive the end plate 5 to move, and when the end plate 5 moves, it will drive the adjustment plate 4 to move. Move the adjustment plate 4 to the measured position. After the adjustment plate 4 moves, turn the adjustment bolt 7 downward. When the adjustment bolt 7 moves downward, it will drive the extrusion head 701 to move downward.
[0032] When the bottom of the extrusion head 701 is completely pressed against the inner wall of the second chute 8, the adjustment plate 4 is subjected to upward tension. At this time, the two L-shaped plates 401 on the adjustment plate 4 generate a resistance because of the hook inside the second chute 8, thereby achieving the fixation of the adjustment plate 4. The other adjustment plate 4 can be adjusted in the same way.
[0033] After adjustment in the above manner, the two adjustment plates 4 will form a fixed leather movement track on the surface of the placement plate 2. During actual processing, the operator pushes the leather along the leather movement track on the placement plate 2 to the bottom of the punch for processing. This can effectively prevent the leather from being offset when pushed to the bottom of the punch, thereby improving the accuracy of punching.
[0034] Preferably: two L-shaped plates 401 are symmetrically installed at the bottom of the adjustment plate 4 located at the upper end of the second slide groove 8, a slider 402 is fixedly installed at the bottom of the adjustment plate 4 located at the upper end of the first slide groove 3, and a threaded hole 403 is opened through the adjustment plate 4 between the two L-shaped plates 401.
[0035] When in use, an indentation is provided on both sides of the inner wall of the second chute 8, and the second chute 8 is a "cross" structure when viewed from the side, and each lateral end of the L-shaped plate 401 is movably connected to one of the indentations;
[0036] A side ear is fixedly installed on both sides of the slider 402, and the side view of the first slide groove 3 also has a "cross" structure. The side ears of the slider 402 are movably connected to the horizontal opening on the first slide groove 3.
[0037] Preferably, a sliding tongue 601 is fixedly installed on one side of the bottom plate 6 , and the sliding tongue 601 is movably installed inside the sliding opening 602 , and the sliding tongue 601 is opened on the outer wall of one side of the placement plate 2 .
[0038] During specific use, the weight of the end plate 5 will be transferred to the sliding tongue 601 through the bottom plate 6. Since the sliding tongue 601 is arranged inside the sliding mouth 602, the weight of the end plate 5 and the bottom plate 6 will be received by the placement plate 2, and when the bottom plate 6 moves, it can also move along the trajectory of the sliding mouth 602 through the sliding tongue 601 to ensure the stability of the moving trajectory of the bottom plate 6.
[0039] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
