Abstract

The utility model discloses a dustpan puncher, which comprises a fixing plate, a punching female die, a guide needle and a punching male die, wherein the punching female die is arranged on the fixing plate; and the guide needle is used for guiding, so that the effect of centering is achieved, and the punching female die and the punching male die are prevented form being damaged by misplacement. The utility model has the advantages that: the dustpan puncher is convenient to use; during use, a specified working environment is not required; in a general small-batch manufacturing process, the requirements of an entire manufacturing process can be met by putting one set of dustpan puncher into use; manufacturing cost is low; manufacturing can be finished by using a high-hardness material of 4 kilograms; in a manufacturing process, only two persons are required for completing the entire flow of dustpan punching; a punching process of a dustpan can be finished within one minute; and oxygen and acetylene can be saved, the environment is not polluted, and cost is reduced.

Description

A kind of winnowing pan piercer

Technical field

The utility model relates to a kind of hole punched device, is a kind of winnowing pan piercer specifically.

Background technology

When winnowing pan is made when making the elevator winnowing pan; Need winnowing pan is dashed four shrinkage pools, formerly beat into shrinkage pool to winnowing pan heating back with iron hammer with oxygen-acetylene before this, such manufacture craft is given personnel's workload increase; Beaing the time that a winnowing pan shrinkage pool taken is 20 minutes; The efficient of making winnowing pan can not improve, and wastes more oxygen-acetylene, makes a winnowing pan and need waste 0.033 bottle of oxygen and acetylene.The shortcoming of the method for this punching of adopting at present is: 1) making winnowing pan piercer material requirements hardness is higher; 2) need man-hour to carry out machined to material adding with lathe; 3) in use, improper like method for using, cause the piercer male model to split off easily.

The utility model content

Goal of the invention: in order to overcome the deficiency of prior art, the purpose of the utility model has been to provide a kind of easy to use, non-environmental-pollution, can have improved the winnowing pan piercer of the operating efficiency of making winnowing pan.

Technical scheme: for realizing above-mentioned technical problem; The technical scheme that the utility model adopts is: a kind of winnowing pan piercer comprises fixed head, punching concave die, guide pin, piercing punch; Said punching concave die is located on the fixed head, and said punching concave die links to each other with piercing punch through guide pin.

In order conveniently to beat when the punching, be fixedly connected with handle in the outside of said piercing punch.

In order to make the depth unanimity of shrinkage pool, said handle welds with said piercing punch is vertical.

Said piercing punch be located at said punching concave die above, the bottom of said guide pin, top are installed in respectively in punching concave die, the piercing punch.

Beneficial effect: compared with prior art; The utility model has the advantages that: easy to use, in use, need not specific working environment; In the general small lot manufacturing process; Only need to satisfy whole making flow process, and cost of manufacture is lower, only needs the higher material of 4KG hardness just can accomplish making once overlapping to come into operation; In the manufacturing process, only need two people operation, just can accomplish the whole flow process of winnowing pan punching; A winnowing pan only needed 1 minute just can accomplish punch process; Ability conserve oxygen and acetylene, free from environmental pollution, thus can minimizing expense expenditure.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done explanation further.

As shown in Figure 1, a kind of winnowing pan piercer comprises fixed head 1; Punching concave die 2, guide pin 3, piercing punch 4; Punching concave die 2 is located on the fixed head 1, piercing punch 4 be located at punching concave die 2 above, the bottom of guide pin 3, top are installed in respectively in punching concave die 2, the piercing punch 4; In order to make guide pin 3 easy for installation, in punching concave die 2, be provided with and the suitable blind hole in the bottom of guide pin 3, in piercing punch 4, be provided with and suitable hole, the top of guide pin 3, and guide pin 3 is vertically installed; Be fixedly connected with handle 5 in the outside of piercing punch 4, handle 5 and piercing punch 4 vertical welding.

In manufacturing process; Winnowing pan is placed on above the punching concave die 2; Beat the handle 5 of piercing punch 4 then with hammer gently, just can form a shrinkage pool, utilize guide pin 3 to lead in this process; Reach effect, and prevent that punching concave die 2 and piercing punch 4 from damaging because of dislocation from alignment.The utility model has not only been saved oxygen-acetylene, and saves human resources, and make efficiency also can significantly be risen.

The above only is the preferred implementation of the utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be regarded as belonging to the protection domain of the utility model.
