Description

Processing die of wood structure anchor rod

Technical Field

The utility model relates to a processing die of a wood anchor rod.

Background

The hardware stamping process is a process for deforming or breaking stainless steel, iron, aluminum, copper and other plates and special materials by using a punch and a die to achieve a certain shape and size. The hardware stamping processing has convenient operation and high production efficiency, is easy to realize mechanization and automation, and is an indispensable important production process for hardware manufacturers. The hardware stamping process flow is generally as follows:

1. preparing materials: the required mould material of different products also differs, and suitable mould material is selected according to the product characteristics, such as a mould handle, an upper cover plate, an upper male clamp, a stripper plate, a lower mould plate, a backing plate and a bottom plate.

2. Rough machining: after the material is selected, the plane and the side surface are preliminarily processed by a milling machine. The common use of male clamping plates, stripper plates, lower die plates and backing plates, bottom plates, upper cover plates and ejector plates is required.

3. Fine processing: the plane and four corners need to be processed by a grinding machine to form right angles. And (3) grinding the surfaces of the male clamping plate, the stripper plate, the lower die plate and the base plate to form right angles, and then grinding the surfaces of the bottom plate and the upper cover plate to form the grinding plane.

4. Scribing: placing the ground and right-angled die plate on a scribing table, scribing by using a scribing height ruler according to a die manufacturing drawing, and finally dotting, drilling and tapping the scribed die plate.

5. And (3) heat treatment: the plate with the hardness improved by the lower template and the module which need to be heat-treated is subjected to high-temperature quenching, tempering, quenching and tempering, annealing, further fine machining, plane grinding and right angle punching, and then linear cutting machining.

6. Assembling and testing a mold: and (3) selecting a die set or a matched guide pillar and a guide sleeve to finish die assembly, mounting the assembled die on a punching machine to perform debugging and punching, and finally measuring the punched die to confirm whether the die meets the requirements of the product or not to finish the whole punching processing. For wood structure hardware, the existing stamping die is heavy in weight and high in cost, and sometimes, multiple test attempts or replacement of the die are required for producing the wood structure connecting piece meeting the requirements, so that the production efficiency is not high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provide a processing die of a wood structure anchor rod, wherein a stamping trial-manufacturing die and a stamping and shaping die are adopted, so that the situation that the defective product rate of waste products is high or the dies are scrapped due to the direct adoption of the stamping die is avoided, and a wood structure connecting piece meeting the requirements can be manufactured by trial more quickly; the stamping trial-manufacturing die and the stamping shaping die are of different structures of normal installation and inverted installation, so that the cost can be saved, and particularly the cost of standard parts of pressure sources required by the movable die plate can be saved.

In order to achieve the purpose, the utility model adopts the technical scheme that the processing die for the wood anchor rod comprises a stamping trial-manufacturing die and a stamping shaping die, wherein the stamping trial-manufacturing die is used for stamping and forming an anchor rod bottom plate, a screw, a connecting pipe and a bottom beam supporting piece of the wood anchor rod, the stamping trial-manufacturing die is of an inverted structure with a male die on the lower part and a female die on the upper part, and the stamping shaping die is of a forward structure with the male die on the upper part and the female die on the lower part, which is used for saving cost. The female die and the male die are positioned through the matched insert block and the slot which are respectively arranged on the female die and the male die; or the positioning and fastening are realized by a guide groove which is arranged on the side end face of the female die or the male die in a protruding way and a positioning pin on a fixed seat of the punching machine, which is the prior art in the field and is not described any more. And the screw and the connecting pipe are subjected to punch forming and then are turned, milled, tapped or rasped to form the required external thread or threaded hole. The two sets of the stamping trial-manufacturing die and the stamping shaping die are adopted, so that the situation that the defective product rate of waste products is high or the dies are scrapped due to the fact that the stamping die is directly adopted is avoided, and the wood structure connecting piece meeting the requirements can be manufactured in a trial mode more quickly; the different structures of the positive installation and the inverse installation of the stamping trial-manufacture die and the stamping shaping die can save the cost, particularly the cost of the standard part of the pressure source required by the movable die plate. The condition of die scrap can be reduced by adopting a trial-manufacture stamping die, two sets of dies are generally trial-manufactured, the first set can generally meet the requirements after being modified without meeting the requirements, the trial-manufacture stamping die is used for pre-stamping, the stamping and shaping die is a second process, all parts of the wood-structure anchor are formed after stamping is completed, and then all the parts are welded, tapped and the like to form a final finished product.

As the stamping oil plays a critical role in the stamping process, the good cooling performance and the extreme pressure antiwear performance have a qualitative leap on the service life of a die and the improvement of the workpiece precision. According to different materials of workpieces, the emphasis points of the performance of the stamping oil during selection are different. Because the wood structural connecting piece is mostly made of stainless steel, and the stainless steel plate is a material which is easy to harden, tensile oil with high oil film strength and good sintering resistance is required to be used. Generally, the stamping oil containing the sulfur-chlorine composite additive is used, so that the extreme pressure performance is ensured, and meanwhile, the problems of burrs, breakage and the like of workpieces are avoided. If the two dies are divided into four sets of dies respectively corresponding to the anchor rod bottom plate, the screw rod, the connecting pipe and the bottom beam support piece, the stress condition can be conveniently analyzed and set according to the shape condition of each part, and the distribution setting condition of the rib plates on the back of the movable die can be conveniently adjusted (the distribution of six radial rib plates is more suitable for the setting of the movable die of the anchor rod bottom plate, the rib plates of other parts are respectively and preferably used for analyzing the stress condition of the movable die according to the shape of each part and then adjusting the number and the distribution form of the rib plates so as to reduce the weight of the movable die).

The utility model has the advantages and beneficial effects that: the two sets of the stamping trial-manufacturing die and the stamping shaping die are adopted, so that the situation that the defective product rate of waste products is high or the dies are scrapped due to the fact that the stamping die is directly adopted is avoided, and the wood structure connecting piece meeting the requirements can be manufactured in a trial mode more quickly; the different structures of the positive installation and the inverse installation of the stamping trial-manufacture die and the stamping shaping die can save the cost, particularly the cost of the standard part of the pressure source required by the movable die plate.
