And through the arranged adjusting mechanism, an operator can conveniently and automatically move the positioning mechanism up and down to detect whether the reinforcement cage is in a vertical and non-inclined state or not and straighten the reinforcement cage, and therefore the using effect of the device can be effectively improved.

A machine for forming knotted fence mesh has a plurality of side by side knot boxes. Each knot box is for forming a knot at an intersection between a line-wire and a stay-wire. Each of the knot boxes has a first pair of formers configured to move towards the line-wire-stay-wire intersection from a front side forming a knot at the line-wire-stay-wire intersection at each operation of the knot box, and a second pair of formers configured to move towards the line-wire-stay-wire intersection from a rear side at each operation of the knot box. The machine has a cam drive system configured to move a plurality of the first pair of formers and the second pair of formers at each operation of the knot boxes. The cam drive system has a front cam assembly having a front pair of cams associated with the first pair of formers and a rear cam assembly having a rear pair of cams associated with the second pair of formers, wherein each of the cams has a respective profile. The profiles of each of the front pair of cams associated are configured such that during a sector of a rotation of the front pair of cams associated, one of the first pair of formers accelerates while the other of the first pair of formers simultaneously decelerates.

A portable fence wrapping machine (20) comprising: a rotating element (1); a wire holder (15) which can hold the required wire length inside / outside the machine; a spiral tube (4) which is rotatably connected to the rotating element and which houses in its hollow interior a rotating thin plate which forms the fence from the wire by motor rotation; a semi-hollow tube (10) which connects the fence wire to the previously developed mesh wires in order to produce the fence in the required length; a cutting tool (6) positioned between the spiral tube and the semi-hollow tube, which precisely cuts the rolled wires after they have been connected to the wire mesh and can be operated by manually pressing the handle; A fence storage rod (11) that holds the long fence in roll form by rotating the rotating blade; A coolant system (17) prevents heat buildup during the winding process and avoids material damage due to excessive heat. The coolant pipe directs the coolant into the spiral tube area to regulate the temperature during material deformation.

The plate grid forming mold of the present invention includes: a frame, a worktable, a pressing demolding mechanism, supporting side plates, a wire assembly plate, a long guide rod assembly, a short guide rod, a middle mold assembly, a side mold assembly, an end pressure plate, and a support platform. The middle mold assembly includes: a middle template and several fixed columns, with several upper through holes at the upper end of the middle template. The side mold assembly includes: a side pressure rod, an upper pressure plate, a lower pressure plate, a pin, a side pressure wheel or side pressure block, and a spring. The long guide rod assembly includes: a push rod, a long guide plate, and a push rod connector. Two long guide plates are fixed on the worktables on both sides of the side mold assembly. The push rod connector and two push rods move between the two long guide plates. The two push rods push the other side of the side pressure rod, causing the side pressure wheel or side pressure block to pass through the side through groove and press against the lead-clad aluminum wire. A material drop groove is opened in the center of the worktable. The supporting side plates move from the center of the worktable to both sides. The pressing demolding mechanism descends and inserts into the upper through holes, causing the lead-clad aluminum wire to fall from the fixed columns into the wire assembly grid of the wire assembly plate.

This application provides a steel cable tie curling and tightening fixture and a steel cable tie curling and tightening method. The steel cable tie curling and tightening fixture is designed to include: an operating mechanism and a spiral rod; wherein: the operating mechanism includes a first handle, a second handle, a transmission mechanism, and a sleeve structure, the sleeve structure and the transmission mechanism are connected by transmission, the sleeve structure is exposed on one side of the first handle, the second handle is rotatably connected to the first handle by a fixing screw and is also connected by transmission to the transmission mechanism, the second handle reciprocating relative to the first handle can drive the sleeve structure to rotate in a preset direction through the transmission mechanism; the spiral rod includes a connected adjusting rod and a tuning fork rod, the end of the adjusting rod is used to connect to the sleeve structure, the sleeve structure can drive the tuning fork rod to rotate through the adjusting rod.

To provide an apparatus for manufacturing reinforcement mesh, and a spinning station therefor.SOLUTION: A spinning station of the present invention includes: a spinner head unit; an upper wire coil and a lower wire coil; a support body; feeding means; a first rod; a first guide wheel; and a cylinder unit. The first guide wheel functions as a wire brake. The cylinder unit acts on the first rod to position the first guide wheel at a first position where a part of a first wire is relatively tightened and position the first guide wheel at a second position where a part of the first wire extending between the spinner head unit and the first guide wheel is relatively loosened.SELECTED DRAWING: Figure 1

The present invention relates to a device for feeding cross wires (1) up and down a production line for a mesh mat (3) consisting of welded cross and longitudinal wires, the device comprising an upper cross wire feeder having a guideway (5) and arranged at a first position in which the cross wire is fed along the guideway of the production line, and a lower cross wire feeder (7) capable of transporting the cross wire to the production line from below, the device being provided with a lower cross wire storage section (8) from which the cross wire can be taken out by the lower cross wire feeder, the upper cross wire feeder being designed as a cross wire exchanger (4) that can be pivoted to at least a second position, by means of which the cross wire exchanger in the second position can load the cross wire into the lower cross wire storage section.

Ensuring a high level of security, particularly with regard to burglary or damage, is currently quite complex for fences, especially those covering large areas. A barred steel fence unit (10) is provided, formed from steel wire (11) arranged to form at least one barred steel mesh (12), wherein the steel wire (11) runs in several spatial directions, and intersecting steel wire sections (12.1) are bonded together to form a semi-finished product (13). According to the invention, the barred steel mesh (12) is formed from thermally hardenable steel wire, and the barred steel fence unit (10) is a hardened barred steel fence unit with a predefined minimum Rockwell hardness. This hardness is achieved by hardening the semi-finished product (13) to at least 45 HRC, such that the barred steel mesh (12) is materially resistant to external influences by means of hardening processes below 45 HRC.The present invention also relates to a bar steel mesh fence assembly (40) and to a system comprising the assembly and at least one detector unit. The present invention also relates to corresponding methods and uses.
