Description

Technical Field

[0001] The utility model relates to the technical field of heavy track plate stamping dies, in particular to a heavy track plate stamping die with an adjustment structure. Background Art

[0002] Track shoes are one of the chassis parts of construction machinery and are a kind of vulnerable parts of the construction machinery used. They are often used in construction machinery such as excavators, bulldozers, crawler cranes, and pavers. Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the required parts.

[0003] For example, the utility model with application number 202020716690.1 discloses a track plate stamping die with adjustable rib positioning. The track plate stamping die with adjustable rib positioning involved in the utility model forms a stamping cavity for stamping the track plate by an upper die stamping assembly connected to an upper die base and a lower die stamping assembly connected to a lower die base. Since the structure of the stamping cavity is fully compatible with the structure of the track plate, it can be effectively stamped, thus overcoming the defects of the prior art that the track plate is difficult to position and stamp, and the stamping effect is poor.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This type of track shoe stamping die with adjustable rib positioning can effectively position the track shoe and improve the stamping effect, but it does not lubricate the guide structure well. Repeated downward stamping of the upper die causes frequent friction between the guide tube and the guide rod, resulting in wear of both and reduced guiding accuracy. In addition, manual lubrication oil must be replenished regularly, which is very inconvenient to use.

[0006] Therefore, a heavy-duty track shoe stamping die with an adjustment structure is designed to optimize the above-mentioned problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a heavy track shoe stamping die with an adjustment structure to solve the related technical problems raised in the above background technology.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] A heavy-duty track shoe stamping die with an adjustment structure comprises a lower die base, an upper die base is arranged on the top of the lower die base, a lower die is installed on the top of the lower die base, an upper die is installed on the bottom of the upper die base, guide columns are evenly arranged on the top of the lower die base, buffer springs are sleeved on the outer sides of the guide columns, guide tubes are sleeved on the outer sides of the guide columns, and the top of the guide tube is fixedly connected to the bottom of the upper die base, oil storage ports aligned with the guide tubes are evenly opened on the top of the upper die base, a sealing bolt is threadedly installed on the top of the oil storage port, a movable rod is slidably installed on the bottom of the oil storage port, a reset spring is sleeved on the outer side of the movable rod, and a conical hole is opened on the top of the movable rod.

[0010] Preferably: a fixed seat is symmetrically installed at the bottom of the lower mold base, an adjusting shaft is rotatably installed between the fixed seats, a positioning block is symmetrically threadedly installed on the outer side of the adjusting shaft, a movable seat is fixed on the top of the positioning block, a limiting roller is evenly rotatably installed on the top of the movable seat, a limiting hole is provided at the connection between the lower mold base and the movable seat, a sliding groove is provided at the connection between the lower mold base and the limiting roller, a limiting rod is rotatably installed on the top of the limiting roller, and a movable opening is provided at the connection between the upper mold base and the limiting rod.

[0011] Preferably, a movable block is fixed to the top end of the guide column, and balls are evenly arranged on the outer side of the movable block.

[0012] Preferably, a rotating block is fixed on the top of the sealing plug, and the rotating block is an anti-slip rotating block.

[0013] Preferably, both ends of the adjusting shaft are fixed with a rotating handle, and an anti-slip layer is provided on the rotating handle.

[0014] Preferably, a buffer layer is provided at the bottom of the movable rod, and the buffer layer is a rubber layer.

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a heavy track shoe stamping die with an adjustment structure. Through the coordinated use of a lower die base, an upper die base, a guide column, a buffer spring, a guide tube, an oil storage port, a sealing bolt, a movable rod, a tapered hole, a reset spring, an upper die and a lower die, the guide column and the guide tube can be lubricated during the stamping of the heavy track shoe, so that the stamping process of the lower die base and the upper die base is more stable. No manual or power source is required for regular lubrication, which saves manpower and material resources, thereby improving the convenience of the heavy track shoe stamping die with an adjustment structure.

[0017] Through the coordinated use of the adjusting shaft, positioning block, movable seat, limiting hole, fixed seat, slide groove, limiting roller, limiting rod and movable mouth, the adjusting shaft is rotated to drive the positioning block and the movable seat to move toward the middle under the limiting effect of the limiting hole, so that the top limiting roller is close to both sides of the heavy track shoe to limit it at the same time, and the heavy track shoe is moved forward to limit it through the limiting roller, which is convenient for unloading and taking materials. There is no need to frequently rotate the adjusting shaft to adjust the spacing of the limiting rollers, which is more convenient to use and can be uniformly adjusted according to the width of the heavy track shoe, with better flexibility.

[0018] Through the coordinated use of the movable block and the ball, the movable block and the ball on the top of the guide column contact the inside of the guide tube when the guide tube moves up and down, and the up and down hard friction is changed into rolling friction, which reduces the friction loss caused by friction force, thereby improving the protective effect of the heavy-duty track shoe stamping die with an adjustment structure.

A return spring 10 is sleeved on the outer side of the movable rod 8, a conical hole 9 is opened on the top of the movable rod 8, a fixed seat 17 is symmetrically installed on the bottom of the lower mold base 1, an adjusting shaft 13 is rotatably installed between the fixed seats 17, a positioning block 14 is symmetrically threadedly installed on the outer side of the adjusting shaft 13, a movable seat 15 is fixed on the top of the positioning block 14, a limiting roller 19 is evenly rotatably installed on the top of the movable seat 15, a limiting hole 16 is opened at the connection between the lower mold base 1 and the movable seat 15, a sliding groove 18 is opened at the connection between the lower mold base 1 and the limiting roller 19, a limiting rod 20 is rotatably installed on the top of the limiting roller 19, and a movable opening 21 is opened at the connection between the upper mold base 2 and the limiting rod 20.

[0026] When the upper die base 2 is punched downward, it drives the guide tube 5 to move downward along the outside of the guide column 3 at the same time, until the top of the guide column 3 contacts and pushes the movable rod 8 to move upward, so that the movable rod 8 squeezes the inside of the oil storage port 6 upward, and the lubricating oil inside the oil storage port 6 is squeezed out through the tapered hole 9 and flows to between the guide column 3 and the guide tube 5 to play a lubricating role. The rotating adjusting shaft 13 drives the positioning block 14 and the movable seat 15 to move toward the middle under the limiting action of the limiting hole 16, so that the top limiting roller 19 is close to both sides of the heavy track shoe to limit it at the same time, and the heavy track shoe is recommended to move forward to limit it through the limiting roller 19, which is convenient for its discharge and removal.
