Abstract
The invention discloses a method for manufacturing knurled channel type bridges. The method includes steps of discharging, leveling, punching, forming, shearing, knurling and the like. The method has the advantages that an upper row of knurled channels and a lower row of knurled channels are formed in two side edges of a channel type bridge by means of rolling, so that the strength of the channel type bridge can be greatly improved, and raw material and energy consumption can be reduced.
Description
Technical field
The invention belongs to cable testing bridge production field, be specifically related to a kind of annular knurl trough type bridge frame production method.
Background technology
Cable testing bridge is divided into step type cable bridge frame, tray type cable bridge, channel-type cable bridge, large span cable bridge rack, composite cable bridge-rack, and wherein channel-type cable bridge is a kind of Totally-enclosed-type cable testing bridge.It is best suited for control cables laying computer cable, communication cable, thermocouple cable and other Highly Sensitive Systems etc.In its shielding interference to control cables and heavy corrosion, the protection of environment cable has good effect.
The traditional production method of trough type bridge frame is blowing, smoothing, punching, moulding, shearing, and the trough type bridge frame processing through these several procedures, exists insufficient strength large, under same intensity prerequisite, consumes more raw material and the energy.The invention provides a kind of novel annular knurl trough type bridge frame and production method, add the step of annular knurl, roll out two rows annular knurl groove at the dual-side of trough type bridge frame, do not increasing under the prerequisite of cost, greatly strengthen the intensity of traditional trough type bridge frame, reduce raw material and energy resource consumption.
Summary of the invention
Technical problem solved by the invention is to have overcome trough type bridge frame insufficient strength, the defect that raw material and energy resource consumption are bigger than normal.The present invention uses edge knurling machine to suppress intensive annular knurl groove at the side plate of trough type bridge frame, and sheet material and energy consumption that the trough type bridge frame that makes the sheet material of condition of equivalent thickness have larger intensity or equality strength uses reduce greatly.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of annular knurl trough type bridge frame production method, comprises blowing, smoothing, punching, moulding, shearing etc., further comprising the steps of:
Annular knurl, rolls out two rows annular knurl groove at the dual-side of trough type bridge frame.
Preferred scheme, the two or more passes of punching punching press simultaneously.
Preferred scheme, edge knurling machine mainly comprises guide frame, knurled portion, smoothing part, running part.
Guide frame: be the guider of plate, to guarantee that the straight centering of plate enters forming section
Knurled portion: mainly formed by frame, left side plate, upper and lower knurled shaft, hydraulic drive etc.Knurled portion: knurled shaft is 400 steel, modified rear finish turning, fine grinding, finishing impression form, and matching part size is accurate, and bending and amount of deflection are functional.
Effect of the present invention is: can strengthen the intensity of trough type bridge frame, reduce raw material and energy resource consumption.
The specific embodiment
The present invention is described further below.
A kind of annular knurl trough type bridge frame production method, comprises blowing, smoothing, punching, moulding, shearing etc., further comprising the steps of:
Annular knurl, rolls out two rows annular knurl groove at the dual-side of trough type bridge frame.Wherein three kinds of passes of punching punching press simultaneously, edge knurling machine mainly comprises guide frame, knurled portion, smoothing part, running part.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
