Description

Technical Field

[0001] This utility model relates to the field of stone-avoiding slab processing, and in particular to a stone-avoiding slab end processing tool. Background Technology

[0002] Stone-avoiding slabs are tools used to remove stones stuck between the rear wheels of mining trucks. They are made of wear-resistant, rigid raw material sheets. During production, the ends of the raw material sheets need to be cut into rounded shapes to prevent scratching the tires when removing stones. Furthermore, for easy transport, a hole needs to be drilled at one end of the sheet to allow it to be hung under the truck bed. In current stone-avoiding slab production processes, the cutting and drilling are done separately, typically requiring two different types of punch presses—a drilling punch and a trimming punch—to operate simultaneously. This process is cumbersome, inefficient, and increases labor and time costs. Utility Model Content

[0045] Reference Figures 1 to 3 As shown, a tooling for processing the end of a stone slab is used in practical applications to simultaneously drill holes and cut and trim the edges of the raw material slab. It includes an upper template 1, an upper knife holder 2, a lower template 3, a lower knife holder 4, and a pressing mechanism 5.

[0046] Specifically, the upper template 1 is connected to the hydraulic press, and a mold handle 11 is fixedly provided at the top of the upper template 1. The mold handle 11 is used for positioning the upper template 1 when it is installed on the hydraulic press. For example, the upper template 1 is fixedly connected to the drive mechanism of the hydraulic press, so that the upper template 1 is driven to move up and down reciprocally under the action of the hydraulic press.

[0047] The upper knife holder 2 is disposed at the bottom end of the upper template 1. The upper knife holder 2 and the upper template 1 are detachably connected by bolts. A punch 21 is installed on the bottom end of the upper knife holder 2. The punch 21 is used to punch holes in the raw material sheet. An upper cutting blade 22 is also disposed on the bottom end of the upper knife holder 2. The upper cutting blade 22 is used to cut and trim the raw material sheet.

[0048] The lower template 3 is located below the upper blade holder 2, and the lower template 3 is adapted to the upper template 1, meaning that the lower template 3 and the upper template 1 have the same shape and size to improve fitting accuracy, ensure uniform force distribution during stamping operations, and reduce stress concentration. The lower blade holder 4 is located at the top of the lower template 3 and below the upper blade holder 2. The lower blade holder 4 is detachably connected to the lower template 3 by bolts, allowing workers to quickly replace the lower blade holder 4. A lower cutting blade 42 is installed on the lower blade holder 4, and the lower cutting blade 42 is adapted to the upper cutting blade 22. That is, when the raw material sheet needs to be cut, the upper cutting blade 22 and the lower cutting blade 42 cooperate to complete the cutting and trimming of the raw material sheet. The lower blade holder 4 is also provided with a die 41 adapted to the punch 21. The die 41 is a through hole penetrating the lower blade holder 4 and the lower template 3, allowing waste material generated after punching the raw material sheet to flow out.

[0049] In some preferred embodiments, a blade pad 43 is also provided on the lower blade holder 4. The blade pad 43 is fixed to the top of the lower blade holder 4 by bolts and is located on one side of the lower cutting blade 42. When the raw material plate is cut and trimmed, the blade pad 43 reduces the impact on the raw material plate, thereby reducing the risk of chipping of the upper cutting blade 22 and the lower cutting blade 42.

[0050] In some preferred embodiments, an inclined groove is provided at one end of the lower template 3 and the lower cutter holder 4. The inclined groove is a material discharge groove, so that the waste generated after the raw material plate is cut and trimmed can flow out from the material discharge groove for collection and treatment.

[0051] More specifically, the punch 21 is a columnar structure adapted to the opening on the raw material sheet. One end of the punch 21 is fixed to the bottom of the upper cutter holder 2 by bolts. The punch 21 is made of high-toughness mold steel to increase its service life. The upper cutting blade 22 is fixedly mounted on the upper cutter holder 2 and is located on one side of the punch 21. The upper cutting blade 22 has a double-blade configuration, meaning that both sides of the upper cutting blade 22 are curved blades adapted to the arc-shaped portion of the raw material sheet that needs to be cut and trimmed, facilitating quick replacement of the blade when one of the upper cutting blades is severely worn or damaged. The lower cutting blade 42 is an arc-shaped cutter disc adapted to the portion of the raw material sheet that needs to be retained, allowing the raw material sheet to be cut and trimmed in cooperation with the upper cutting blade 22 and the lower cutting blade 42.

[0052] In this embodiment, the pressing mechanism 5 is disposed on the upper template 1 and located between the upper cutter holder 2 and the lower cutter holder 4. The pressing mechanism 5 is used to press the raw material sheet during the punching operation and to demold the raw material sheet after the punching operation is completed. It can be understood that the punching operation refers to the general term for punching and cutting trimming operations on the raw material sheet. Specifically, the pressing mechanism 5 includes a pressing plate 51, two elastic components 52, and several pressure plate guide pillars 53.

[0053] The pressure plate 51 is disposed between the upper cutting blade 22 and the lower cutting blade 42. During the punching operation of the raw material sheet, it presses the raw material sheet onto the lower cutting blade 42 to prevent it from moving due to impact force, thus improving punching accuracy. The pressure plate 51 has a notch at its center that matches the punch 21 and the upper cutting blade 22 to prevent collisions and damage during punching. Preferably, the pressure plate 51 has an inwardly recessed mounting groove at its center, within which an inner unloading plate 511 is disposed. The inner unloading plate 511 is detachably connected to the pressure plate 51 by bolts. The inner unloading plate 511 is also provided with a guide hole, which is a through hole adapted to the punch 21. The guide hole is used to guide the movement of the punch 21 and to provide lateral support for the punch 21 during the stamping operation, thereby reducing the possibility of the punch 21 breaking or bending due to uneven force.

[0054] Two elastic components 52 are symmetrically arranged at both ends of the upper template 1, and both elastic components 52 are connected to the pressure plate 51. The elastic components 52 are used to apply elastic force to the pressure plate 51, so that the pressure plate 51 can press and demold the raw material sheet through the elastic force. Specifically, for ease of explanation, one elastic component 52 will be described here. The elastic component 52 includes a spring seat plate 521, a pressure plate spring 522, and a spring guide rod 523. The spring seat plate 521 is fixedly arranged at the bottom end of the upper template 1, and spring seats are also provided at both ends of the spring seat plate 521. The pressure plate spring 522 is arranged between the spring seat and the pressure plate 51, that is, the two ends of the pressure plate spring 522 are fixedly connected to the spring seat and the pressure plate 51 respectively. The spring guide rod 523 is arranged between the spring seat and the pressure plate 51, and the spring guide rod 523 passes through the pressure plate 51 and is threadedly connected to the spring seat. The spring guide rod 523 is a bolt structure, consisting of a threaded rod and a hexagonal head. The rod is threaded to the spring seat, while the head is located at the bottom of the pressure plate 51 to prevent it from falling off. In this embodiment, the distance between the upper template 1 and the pressure plate 51 is adjusted by rotating the spring guide rod 523 to adjust the depth of its screw-in into the spring seat, and simultaneously the length compression of the pressure plate spring 522 is adjusted, thereby adjusting the elastic force on the pressure plate 51. For example, when it is necessary to reduce the distance between the upper template 1 and the pressure plate 51, this can be achieved by rotating the spring guide rod 523 clockwise to increase its screw-in depth.

[0055] In this embodiment, when the upper template 1 moves toward the lower template 3, the upper template 1 drives the pressure plate 51 to move. At this time, the pressure plate 51 contacts the raw material sheet before the punch 21 and the upper cutting blade 22. When the pressure plate 51 contacts the raw material sheet, the pressure plate 51 is pressed and squeezes the pressure spring 522, causing the pressure spring 522 to contract and deform, generating an upward elastic force on the pressure plate 51. At this time, the raw material sheet is pressed downward by the combined force of the weight of the pressure plate 51 and the elastic force of the pressure spring 522, so that the pressure plate 51 firmly holds the raw material sheet. The punch 21 and the upper cutting blade 22 are pressed onto the lower cutting blade 42. When the punching and cutting are completed and the upper template 1 moves upward, the punch 21 and the upper cutting blade 22 are the first to move upward and separate from the raw material plate. Since the position of the pressure plate 51 is lower than the punch 21 and the upper cutting blade 22 (that is, the distance between the upper template 1 and the pressure plate 51 is greater than the length of the punch 21 and the thickness of the upper cutting blade 22), the pressure plate spring 522 is still in a compressed state and continues to apply downward pressure to the pressure plate 51, so that the pressure plate 51 continues to press the raw material plate, assisting it to complete the demolding process and preventing the plate from sticking to the punch 21 or the blade.

[0056] The tooling also includes a guiding mechanism 6, which is disposed between the upper template 1 and the lower template 3 to guide the movement trajectory of the upper template 1, prevent it from deviating, and improve machining accuracy. Specifically, the guiding mechanism 6 includes a guide sleeve 61 and a guide post 62. The guide sleeve 61 is disposed at the bottom end of the upper template 1, and the guide post 62 is disposed at the top end of the lower template 3 and is adapted to the guide sleeve 61. When the upper template 1 moves downward, the guide sleeve 61 is fitted onto the guide post 62, causing the upper template 1 to move along the guide post 62.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
