Description

Technical Field

[0001] The utility model relates to the field of lead brick production equipment, and specifically discloses a lead brick production cold extrusion equipment. Background Art

[0002] Lead bricks are made of the highest quality lead with standard hardness and a flat and smooth surface, allowing for perfectly flush installation even at sharp angles. They are primarily used to provide protection against radioactive radiation in laboratories and work environments (wall mounting).

[0003] In the process of extruding lead ingots through lead brick molds, the existing cold extrusion equipment used for lead brick production cannot directly push out and unload the formed lead bricks through the cold pressing rod. When the lead bricks are taken out of the lead brick mold, they will produce friction with the forming surface of the lead brick mold, which will easily cause cracks on the surface of the lead bricks. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, the present application aims to provide a cold extrusion equipment for lead brick production, comprising a lead brick mold fixedly mounted on the extrusion equipment and a feed cavity arranged inside the lead brick mold, wherein the outer side of the lead brick mold is fixedly mounted with a first forming mechanism and a second forming mechanism slidably connected to the inner side of the lead brick mold through an opening and closing mechanism, and the outer side of the lead brick mold is provided with two symmetrically distributed fixed seats located on one side of the opening and closing mechanism, the interior of the fixed seat is fixedly sleeved with a push-pull mechanism located on one side of the lead brick mold, and one side of the push-pull mechanism is fixedly mounted with a cold pressing rod adapted to the feed cavity through an extension rod.

[0005] Preferably, the first forming mechanism comprises a first L-shaped frame fixedly mounted on the inner side of the opening and closing mechanism, and the first L-shaped frame is respectively provided with vertically distributed first slide rails and first forming blocks.

[0006] Preferably, the second forming mechanism includes a second L-shaped frame fixedly installed on the inner side of the opening and closing mechanism, and the second L-shaped frame is respectively provided with a vertically distributed second slide rail and a second forming block, and the second L-shaped frame, the lead brick mold, the second forming block, the first L-shaped frame and the first forming block form a forming cavity for the lead brick.

[0007] Preferably, the push-pull mechanism includes a fixed rod fixedly sleeved inside the fixed seat, a second fixed frame is fixedly sleeved on the outer side of one end of the fixed rod, a second hydraulic cylinder is fixedly sleeved inside the second fixed frame, and a mounting plate is fixedly sleeved on the outer side of one end of the second hydraulic cylinder, which is movably sleeved on the outer side of the fixed rod and fixedly mounted on one side of the extension rod.

[0008] Preferably, the opening and closing mechanism includes a first guide rod and a second guide rod which are arranged on the outside of the lead brick mold and movably sleeved inside the first L-shaped frame and the second L-shaped frame, one end of the first guide rod and the second guide rod are commonly fixedly sleeved with a first fixing frame, and the interior of the first fixing frame is fixedly sleeved with a first hydraulic cylinder whose one end is respectively fixedly sleeved inside one side of the first L-shaped frame and the second L-shaped frame.

[0009] Preferably, a slide groove adapted to the first slide rail and the second slide rail is provided on the inner side of the lead brick mold.

[0010] Beneficial effects:

[0011] 1. The lead brick production cold extrusion equipment can drive the cold pressing rod through the extension rod to extrude the lead ingot placed inside the feed chamber through the drive of the second hydraulic cylinder. After the lead brick is formed, the first hydraulic cylinder can drive the first L-shaped frame and the second L-shaped frame to move, thereby opening the forming cavity surrounded by the first L-shaped frame, the first forming block, the second L-shaped frame, the second forming block and the lead brick mold. Under the further drive of the second hydraulic cylinder, the formed lead brick is directly pushed out from the inside of the feed chamber to the conveyor line on the extrusion equipment through the cold pressing rod. The use of this mechanism makes it convenient to directly unload the lead brick after it is formed.

[0012] 2. The cold extrusion equipment for lead brick production can reduce the contact area with the lead brick by opening the first L-shaped frame and the second L-shaped frame, so that the friction between the lead brick and the feed cavity is reduced when the lead brick is moved out from the inner side of the lead brick mold, and the lead brick is easily pushed out and unloaded by the cold pressing rod, and the force area of the lead brick is reduced, making it less likely to crack on its surface during unloading.

[0026] Among them, the push-pull mechanism 7 includes a fixed rod 71 fixedly sleeved inside the fixed seat 6, a second fixed frame 72 is fixedly sleeved on the outer side of one end of the fixed rod 71, and a second hydraulic cylinder 73 is fixedly sleeved inside the second fixed frame 72. The outer side of one end of the second hydraulic cylinder 73 is fixedly sleeved with a mounting plate 74 that is movably sleeved on the outer side of the fixed rod 71 and fixedly mounted on one side of the extension rod 8. The drive of the second hydraulic cylinder 73 can drive the cold pressing rod 9 to move, thereby realizing the forming and automatic unloading of lead bricks.

[0027] Among them, the opening and closing mechanism 3 includes a first guide rod 31 and a second guide rod 32 arranged on the outside of the lead brick mold 1 and movably sleeved on the inside of the first L-shaped frame 41 and the second L-shaped frame 51.

After the lead brick is formed, the first hydraulic cylinder 34 is started, and the cold pressing rod 9 is driven by the first hydraulic cylinder 34 to move the lead ingot. The first L-shaped frame 41 and the second L-shaped frame 51 are moved to open the formed forming cavity, and the second hydraulic cylinder 73 is started. The cold pressing rod 9 is driven by the second hydraulic cylinder 73 to push the lead brick from the inner side of the lead brick mold 1 to the conveyor line on the extrusion equipment.
