Description

Technical Field

[0001] This utility model belongs to the field of copper waterstop processing technology, and relates to a tool holder for processing and manufacturing T-shaped copper waterstops. Background Technology

[0002] Copper waterstops, also known as copper waterstop sheets, are a highly stable, low-maintenance roofing and curtain wall material. They are environmentally friendly, safe to use, easy to process, and extremely corrosion-resistant. Their yield strength and elongation are inversely proportional; the hardness of copper plates increases significantly after processing and bending, but this can be reduced through heat treatment. Among all building metal materials, copper's elongation properties offer a significant advantage in adapting to architectural shapes. Copper plates are not limited by processing temperature; they do not become brittle at low temperatures, and at high melting points, they can be welded using hot-melt methods such as oxygen blowing. Even in highly corrosive atmospheric environments, copper plates form a strong, non-toxic passivation protective layer, commonly known as "verdigris." Its chemical composition depends on the air conditions of the region, but the protective effect of various "verdigris" on copper plates is essentially the same. This passivation film is very stable, can automatically repair itself when damaged, and is indistinguishable to the naked eye.

[0003] Copper waterstops possess excellent corrosion resistance, high compressive strength, and good deformability, making them suitable for foundation waterstops and dam waterstops in advanced hydraulic structures. They are widely used in most infrastructure projects. However, existing copper waterstop processing tools are complex in structure, have high manufacturing costs, and require significant procurement expenses. Therefore, construction sites typically have them processed at specialized copper waterstop shops. However, most construction sites are far from towns, and towns generally lack copper waterstop processing shops. Even if copper waterstops are processed elsewhere and delivered to the site, proper storage is difficult. The required length of copper waterstops for each use is uncertain, leading to numerous cutting operations, increased welding joints, and significant copper waste during subsequent use. Utility Model Content

[0004] The purpose of this invention is to provide a tool holder for processing and manufacturing T-shaped copper waterstops, which solves the problem that existing T-shaped copper waterstop tool holders are complex in structure and difficult to manufacture.

[0005] The technical solution adopted in this utility model is a tool holder for processing and manufacturing T-shaped copper waterstops, including a fixed frame. Inside the fixed frame, from top to bottom, a fixed tool holder body, a movable tool groove body, two hydraulic jacks, and a fixed base plate are installed sequentially. The fixed tool holder body is fixed on the fixed frame. The fixed tool holder body includes a tool holder top beam channel steel, a cutting edge round steel bar, and two pressure steel plates. The two pressure steel plates are fixed relative to each other on the bottom surface of the tool holder top beam channel steel. The cutting edge round steel bar is fixed to the bottom end of the two pressure steel plates. One end of the pressure steel plate is an arc-shaped cutting head end, and the other end is square. The movable tool groove body is slidably connected to the fixed frame. A tool groove is provided in the middle of the movable tool groove body. The cutting edge round steel bar is arranged vertically opposite to the tool groove. The free ends of the pistons of the two hydraulic jacks are fixed on opposite sides of the bottom surface of the movable tool groove body. The bottoms of the two hydraulic jacks are fixed on the fixed base plate.

[0006] The fixed gantry is a square frame structure formed by welding steel profiles, including columns and beams.

[0007] The movable cutter groove body includes two cutter groove channels and two corner limiting steel plates. The cutter groove is located between the two cutter groove channels. The two cutter groove channels are connected and fixed by the two corner limiting steel plates, which are respectively fixed at the bottom of opposite ends of the cutter groove channels.

[0008] The four corner limiting steel plates have right-angle limiting grooves at their ends, and the columns that fix the gantry are located in the right-angle limiting grooves.

[0009] Two cutting channel steels are fixed to the bottom of the connecting channel steels, which are located between two corner limiting steel plates.

[0010] Two hydraulic jacks are fixed near the two ends of the cutter groove.

[0011] The base plate is welded and fixed to the fixed gantry.

[0012] The fixed base plate is formed by welding multiple channel steel pieces side by side.

[0013] The stroke of the hydraulic jack cylinder is greater than the height difference between the upper surface of the cutter slot channel steel and the lower surface of the cutter holder top beam channel steel.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By sequentially installing a fixed knife holder body, a movable knife groove body, two hydraulic jacks and a fixed base plate inside the fixed frame, a knife holder for processing and manufacturing T-shaped copper waterstops is formed. The structure is simple and easy to manufacture. Materials can be sourced locally on the construction site. It is economical and practical. It solves the problem that most construction sites are far from towns and towns generally do not have a special pressing machine for shaping and pressing copper waterstops. It requires long-distance external processing, which saves a lot of trouble caused by external processing and saves high processing fees and round-trip transportation fees.

[0016] (2) The fixed tool holder body includes a tool holder top beam channel steel, a cutting edge round steel bar and two pressure steel plates. The two pressure steel plates are fixed to the bottom surface of the tool holder top beam channel steel. The cutting edge round steel bar is fixed to the bottom end of the two pressure steel plates. One end of the pressure steel plate is an arc-shaped cutting head end and the other end is square. The arc-shaped cutting head end and the cutting edge round steel bar ensure that the copper sheet is gradually pressed during the processing of copper waterstop. Under the pressure of the blunt cutting edge, the copper sheet is not crushed or damaged. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] A tool holder for machining T-shaped copper waterstops, see [link / reference]. Figures 1-3The system includes a fixed gantry 1. Inside the fixed gantry 1, from top to bottom, are a fixed blade holder body 2, a movable blade groove body 3, two hydraulic jacks 4, and a fixed base plate 5. The fixed blade holder body 2 is fixed to the fixed gantry 1. The fixed blade holder body 2 includes a blade holder top beam channel steel 21, a blade edge round steel bar 23, and two pressure blade steel plates 22. The two pressure blade steel plates 22 are fixed to the bottom surface of the blade holder top beam channel steel 21. The blade edge round steel bar 23 is fixed to the bottom end of the two pressure blade steel plates 22. One end of the pressure blade steel plate 22 is an arc-shaped blade head end, and the other end is square. The movable blade groove body 3 is slidably connected to the fixed gantry 1. A blade groove 34 is provided in the middle of the movable blade groove body 3. The blade edge round steel bar 23 and the blade groove 34 are arranged vertically opposite each other. The free ends of the pistons of the two hydraulic jacks 4 are fixed to opposite sides of the bottom surface of the movable blade groove body 3. The bottoms of the two hydraulic jacks 4 are fixed to the fixed base plate 5.

[0028] This utility model consists of a fixed tool holder, a movable tool groove, two hydraulic jacks, and a fixed base plate installed sequentially inside a fixed frame to form a tool holder for processing T-shaped copper waterstops. The structure is simple, easy to manufacture, and allows for the use of locally sourced materials, making it economical and practical. It solves the problem that most construction sites are far from towns, where there are generally no dedicated copper waterstop shaping and pressing machines available, requiring long-distance outsourcing for processing. This invention eliminates the hassle of outsourcing and saves on high processing and transportation costs.

[0029] With a self-made T-shaped copper waterstop cutting tool holder on-site, copper sheets can be processed as needed, in any quantity and length required. When not in use, the copper sheets can be stored in a warehouse for easy handling. If copper waterstops are outsourced for processing, transportation limitations generally result in shorter cutting lengths, more cutting operations, and increased welding joints during subsequent use, leading to significant copper waste. Having a self-made T-shaped copper waterstop cutting tool holder on-site allows for on-site cutting to the required length in one go, reducing copper waste.

[0066] When using this utility model to process and manufacture a T-shaped copper waterstop, the copper sheet roll is unrolled according to the required amount. Along the center line of the fixed tool holder 2 and the movable tool groove 3, the copper sheet is passed through the movable space of the fixed tool holder 2 and the movable tool groove 3 when the hydraulic jack is not pressurized. The center line of the copper sheet is aligned with the center lines of the fixed tool holder 2 and the movable tool groove 3. After slightly fixing the copper sheet, the hydraulic jack is pressed down. Under the gradual increase of pressure from the hydraulic jack, the fixed tool holder 2, the movable tool groove 3, and the copper sheet are tightly fitted together. Under the bidirectional forced force of the socket-type pressing tool and the tool groove, the center of the copper sheet is pressed into the tool groove along with the pressing tool. After the external force is released, the copper sheet maintains its own rigidity and cannot return to its original planar state after deformation. The center line then forms the T-shaped nose we need. The movable tool groove 3 falls down, and the pressed and formed T-shaped copper waterstop 6 is removed. The T-shaped copper waterstop processing and manufacturing is thus completed. (See below) Figure 7 .
